ENCYCLICAL  LETTER 

OF 

OUR  HOLY  FATHER 

BY    DIVINE    PROVIDENCE 

POPE    LEO    XIII. 

ON 

THE    RESTORATION    OF    CHRISTIAN 
PHILOSOPHY, 

ACCORDING    TO    THE    MIND    OF 

ST.  THOMAS  AQUINAS,  THE  ANGELIC  DOCTOR 


To  His  Venerable  Brethren,  all  the  Patriarchs,  Primates, 
Archbishops,  and  Bishops  of  the  Catholic  World,  in 
favour  and  communion  with  the  Apostolic  See, 

POPE  LEO  XIII. 

Venerable  Brethren, 

Health  and  Apostolic  Benediction. 
The  Only-begotten  Son  of  the  Eternal  Father  appeared 
on  earth  to  bring  salvation  and  the  light  of  the  wisdom  of 
God  to  the  human  race.  As  He  was  ascending  to  Heaven 
He  bestowed  on  the  world  a  blessing,  truly  great  and 
wondrous,  when,  commanding  His  Apostles  to  '  go  and 
teach  all  nations,'*  He  left  a  Church,  founded  by  Himself, 
as  the  universal  and  supreme  mistress  of  all  people.  Man, 
''whom  the  truth  had  set  free,  was  to  be  kept  safe  by  the  truth. 
Indeed,  the  fruits  of  heavenly  doctrine,  by  which  salvation 
was  gained  for  man,  could  not  have  endured  for  long  unless 
Christ  our  Lord  had  set  up  a  perpetual  teaching  authority 
{magisterium)  for  the  instruction  of  souls  in  the  faith.  This 
Church,  then,  not  only  built  on  the  promises  of  its  Divine 
Author,  but  following  in  His  love,  has  kept  His  commands. 
She  has  always  looked  to  one  end,  and  desired  it  with  great 
desire  ;  that  is,  to  teach  the  true  religion  and  wage  ceaseless 
war  with  error.  For  this  there  have  been  the  watchful 
labours  of  Bishops,  each  in  his  own  place  ;  and  for  this 
Councils  have  made  laws  and  decrees.  More  than  all,  for 
this  there  has  been  the  daily  anxiety  of  the  Roman  Pontiffs. 
They  are  the  successors  of  Blessed  Peter,  the  Prince  of  the 
Apostles,  in  his  Primacy,  and  therefore  it  is  their  right  and 

*  Matt,  xxviii.  19.

X  THE  *'  SUMMA  THEOLOGICA  " 

their  duty  to  teach  the  brethren,  and  confirm  them  in  the 
faith. 

Now,  the  Apostle  warns  us  that  the  faithful  of  Christ  are 
often  deceived  in  mind  '  by  philosophy  and  vain  deceit,'* 
and  that  thus  the  sincerity  of  faith  is  corrupted  in  men. 
For  this  reason  the  Supreme  Pastors  of  the  Church  have 
always  held  that  it  is  part  of  their  office  to  advance,  with 
all  their  power,  knowledge  truly  so  called  ;  but  at  the  same 
time  to  watch  with  the  greatest  care  that  all  human  learning 
shall  be  imparted  according  to  the  rule  of  the  Catholic 
faith.  Especially  is  this  true  of  'philosophy,'  on  which 
the  right  treatment  of  other  sciences  depends  in  great 
measure.  We  Ourselves  spoke  to  you  shortly  of  this,  among 
other  things,  Venerable  Brothers,  when  first  We  addressed 
you  all  by  an  Encyclical  Letter.  Now,  by  the  importance 
of  this  matter,  and  by  the  state  of  the  times.  We  are  forced 
again  to  write  to  you,  that  you  may  so  organize  the  course 
of  philosophical  studies  as  to  insure  their  perfect  correspon- 
dence with  the  gift  of  Faith,  and  also  their  agreement  with 
the  dignity  of  human  knowledge. 

If  anyone  look  carefully  at  the  bitterness  of  our  times, 
and  if,  further,  he  consider  earnestly  the  cause  of  those 
things  that  are  done  in  public  and  in  private,  he  will  dis- 
cover with  certainty  the  fruitful  root  of  the  evils  which  are 
now  overwhelming  us,  and  of  the  evils  which  we  greatly 
fear.  The  cause  he  will  find  to  consist  in  this — evil  teaching 
about  things,  human  and  divine,  has  come  forth  from  the 
schools  of  philosophers  ;  it  has  crept  into  all  the  orders  of 
the  State  ;  and  it  has  been  received  with  the  common  ap- 
plause of  very  many.  Now,  it  has  been  implanted  in  man 
by  Nature  to  follow  reason  as  the  guide  of  his  actions,  and 
therefore,  if  the  understanding  go  wrong  in  anything,  the 
will  easily  follows.  Hence  it  comes  about  that  wicked 
opinions  in  the  understanding,  flow  into  human  actions 
and  make  them  bad.  On  the  other  hand,  if  the  mind  of 
man  be  healthy,  and  strongly  grounded  in  solid  and  true 
principles,  it  will  assuredly  be  the  source  of  great  blessings, 

*  Col.  ii.  8.

both  as  regards  the  good  of  individuals  and  as  regards  the 
common  weal. 

We  do  not,  indeed,  attribute  to  human  philosophy  such 
force  and  authority  as  to  judge  it  sufficient  for  the  utter 
shutting  out  and  uprooting  of  all  errors.  When  the  Chris- 
tian religion  was  first  established  by  the  wondrous  light  of 
Faith  shed  abroad,  '  not  in  the  persuasive  words  of  human 
wisdom,*  but  in  showing  of  the  Spirit  and  power,'  the  whole 
world  was  restored  to  its  primeval  dignity.  So  also  now, 
chiefly  from  the  almighty  power  and  help  of  God,  we  may 
hope  that  the  darkness  of  error  will  be  taken  away  from  the 
minds  of  men,  and  that  they  will  repent.  But  we  must  not 
despise  or  undervalue  those  natural  helps  which  are  given 
to  man  by  the  kindness  and  wisdom  of  God,  Who  strongly 
and  sweetly  orders  all  things  ;  and  it  stands  to  reason  that 
a  right  use  of  philosophy  is  the  greatest  of  these  helps.  For 
God  did  not  give  the  light  of  reason  in  vain  to  the  soul  of 
man,  nor  does  the  superadded  light  of  Faith  quench,  or  even 
lessen,  the  strength  of  the  understanding.  Its  effect  is  far 
from  this.  It  perfects  the  understanding,  gives  it  new 
strength,  and  makes  it  fit  for  greater  works.  The  very 
nature  of  the  providence  of  God  Himself,  therefore,  makes 
it  needful  for  us  to  seek  a  safeguard  in  human  knowledge 
when  we  strive  to  bring  back  the  people  to  Faith  and  salva- 
tion. The  records  of  antiquity  bear  witness  that  this 
method,  both  probable  and  wise,  was  used  habitually  by 
the  most  illustrious  Fathers  of  the  Church.  They,  in  truth, 
were  wont  to  give  to  reason  offices  neither  few  nor  small ; 
and  these  the  great  Augustine  has  summed  up  very  shortly  : 
'  Attributing  to  this  science  .  .  .  that  by  which  the  life- 
giving  Faith  ...  is  begotten,  nourished,  guarded,  and 
strengthened.' 

In  the  first  place,  then,  if  philosophy  be  rightly  and  wisely 
used,  it  is  able  in  a  certain  measure  to  pave  and  to  guard 
the  road  to  the  true  Faith ;  and  is  able,  also,  to  prepare  the 
minds  of  its  followers  in  a  fitting  way  for  the  receiving  of 
revelation.     Hence  it  has  not  untruly  been  called  by  the 

♦  I  Cor.  ii.  4. 


xii  THE  "  SUMMA  THEOLOGICA  " 

ancients  *  an  education  leading  to  the  Christian  Faith,'  '  a 
prelude  and  help  of  Christianity,'  '  a  schoolmaster  for  the 
Gospel.' 

In  truth,  the  loving-kindness  of  God,  with  regard  to  the 
things  concerning  Himself,  has  not  only  made  known  by  the 
light  of  Faith  many  truths  beyond  the  reach  of  the  human 
understanding,  but  has  also  revealed  some  which  are  not 
altogether  beyond  the  power  of  reason  to  find  out.  Such 
truths,  when  the  authority  of  God  is  thus  added,  become 
known  to  all  both  at  once  and  without  any  mixture  of 
error.  This  being  so,  certain  truths,  either  divinely  revealed 
to  us  for  our  belief,  or  bound  up  closely  with  the  doctrine 
of  the  Faith,  were  known  to  wise  men  among  the  Gentiles, 
who  were  guided  only  by  the  light  of  natural  reason.  By 
fitting  arguments  they  vindicated  and  demonstrated  these 
truths.  St.  Paul  says  :  '  The  invisible  things  of  Him,  from 
the  creation  of  the  world,  are  clearly  seen,  being  understood 
by  the  things  that  are  made  ;  His  eternal  power  also  and 
divinity.'  Again  :  '  The  Gentiles,  who  have  not  the  law,' 
nevertheless  *  show  the  work  of  the  law  written  in  their 
hearts.' 

It  is  opportune,  therefore,  in  a  high  degree  to  use,  for  the 
good  and  the  advantage  of  revealed  truth,  these  other  truths 
that  were  known  even  to  wise  heathens  ;  for  thus  human 
wisdom,  and  the  very  testimony  of  the  adversaries,  give 
their  witness  to  the  Catholic  Faith.  Further,  it  is  plain  that 
this  way  of  treating  the  question  is  not  a  thing  newly 
devised,  but  an  ancient  way  very  much  used  by  the  holy 
Fathers  of  the  Church.  Moreover,  these  venerable  wit- 
nesses and  guardians  of  holy  traditions  see  a  kind  of  form 
of  this,  and  almost  a  type  of  it,  in  one  action  of  the  Hebrews  ; 
who,  as  they  were  going  out  of  Egypt,  were  commanded  to 
take  with  them  vessels  of  silver  and  of  gold,  with  precious 
garments  of  the  Egyptians.  This  was  done  that,  by  a  use 
suddenly  changed,  the  riches  which  had  ministered  to  super- 
stition and  to  rites  of  ignominy  might  be  dedicated  to  the 
service  of  the  true  God.  Gregory  of  Neocaesaraea  praises 
Origen  for  this  very  reason,  that,  skilfully  gathering  together 


ENCYCLICAL  OF  LEO  XIIL  xiii 

much  of  the  teaching  of  the  Gentiles  for  the  defence  of 
Christian  wisdom,  and  for  the  destruction  of  superstition, 
he  used  these  things  as  weapons  taken  from  the  enemy,  and 
with  wondrous  power  hurled  them  back.  Both  Gregory 
Nazianzen  and  Gregory  of  Nyssa  approve  and  praise  this 
manner  of  teaching  in  Basil  the  Great.  So  also  Jerome 
greatly  commends  the  same  thing  in  Quadratus,  a  disciple 
of  the  Apostles ;  in  Aristides,  in  Justin,  in  Irenseus,  and  in 
very  many  others.  Augustine  also  says  :  *  Do  we  not  see 
how  Cyprian,  that  doctor  of  great  sweetness  and  that 
mart5n:  of  great  blessedness,  was  laden  with  gold  and  silver 
and  raiment  when  he  went  forth  from  Egypt  ?  Was  it  not 
so  with  Lactantius,  with  Victorinus,  Optatus,  and  Hilary  ? 
Not  to  speak  of  the  living,  was  it  not  so  with  coimtless 
Greeks  ?*  If,  then,  natural  reason  produced  so  rich  a 
crop  of  learning  as  this  before  it  was  fertilized  by  the 
power  and  working  of  Christ,  much  more  abundant  will 
be  its  harvests  now,  when  the  grace  of  the  Saviour  renews 
and  increases  the  inborn  powers  of  the  mind  of  man.  Is 
there,  indeed,  anyone  who  does  not  see  that  a  plain  and 
easy  road  is  opened  to  the  Faith  by  philosophy  such  as 
this  ? 

The  usefulness,  however,  which  springs  from  such  a  way 
of  studying  philosophy  is  not  confined  within  these  limits  ; 
for  in  truth  severe  reproof  is  given,  in  the  words  of  the 
wisdom  of  God,  to  the  foolishness  of  those  men  who,  '  by 
these  good  things  that  are  seen,  could  not  understand  Him 
that  is  ;  neither,  by  attending  to  the  works,  have  acknow- 
ledged (Him)  who  was  the  workman.' 

In  the  first  place,  then,  this  great  and  glorious  fruit  is 
gathered  from  human  reason — namely,  that  it  demonstrates 
the  existence  of  God  :  '  By  the  greatness  of  the  beauty  and 
of  the  creature  the  Creator  of  them  may  be  seen,  so  as  to 
be  known  thereby.' 

In  the  next  place,  reason  shows  that  God,  in  a  way 
belonging  only  to  Himself,  excels  by  the  sum  of  all  per- 
fections— that  is,  by  an  infinite  wisdom,  from  which  nothing 
can  be  hidden  ;  and  also  by  a  supreme  justice  which  no 


xiv  THE  "SUMMA  THEOLOGICA  " 

affection  of  evil  can  touch.  Hence  reason  proves  that  God 
is  not  only  true,  but  the  very  Truth  itself,  which  cannot 
deceive  or  be  deceived.  Further,  it  is  a  clear  consequence 
from  this  that  the  human  reason  obtains  for  the  word  of 
God  full  belief  and  authority. 

In  like  manner  reason  declares  that  the  evangelical  doc- 
trine has  shone  as  the  light  from  its  very  beginning,  by 
signs  and  miracles  which  are  infallible  proofs  of  infallible 
truth  ;  and  that  therefore  they  who  receive  the  Faith  by  the 
Gospel  do  not  act  rashly,  as  if  they  had  '  followed  cunningly 
devised  fables,'  but,  by  an  obedience  that  is  altogether 
reasonable,  submit  their  understanding  and  their  judgment 
to  the  authority  of  God. 

Further,  not  less  than  these  things  in  value  is  it  that 
reason  clearly  shows  us  the  truth  about  the  Church  instituted 
by  Christ.  That  Church,  as  the  Vatican  Synod  decreed — ■ 
'  because  of  the  wonderful  way  in  which  it  spreads  ;  be- 
cause of  its  great  holiness  and  inexhaustible  fruitfulness 
in  all  places  ;  because  of  its  Catholic  unity  and  invincible 
stability — is  in  itself  a  great  and  perpetual  motive  of 
credibility,  and  an  unanswerable  argument  for  its  own 
Divine  legation.' 

The  foundations,  then,  having  been  laid  in  the  most  solid 
way,  there  is  needed,  further,  a  use  of  philosophy,  both  per- 
petual and  manifold,  in  order  that  Sacred  Theology  may 
assume  and  put  on  the  nature,  habit,  and  character  of  true 
science.  For  in  this  noblest  kind  of  learning  it  is  above 
everything  necessary  that  the  parts  of  heavenly  doctrine, 
being  many  and  different,  should  be  gathered  together,  as 
it  were,  into  one  body.  Thus  they  are  united  by  a  union 
of  harmony  among  themselves,  all  the  parts  being  fittingly 
arranged,  and  derived  from  their  own  proper  principles. 
Lastly,  all  of  these  parts,  and  each  of  them,  must  be 
strengthened  by  unanswerable  arguments  suited  to  each 
case. 

Nor  must  we  pass  by  in  silence,  or  reckon  of  little  account, 
that  fuller  knowledge  of  our  belief,  and,  as  far  as  may  be, 
that  clearer  understanding  of  the  mysteries  of  the  faith 


ENCYCLICAL  OF  LEO  XIIL  xv 

which  Augustine  and  other  Fathers  praised,  and  laboured 
to  attain,  and  which  the  Vatican  Synod  itself  decreed  to  be 
very  fruitful.  Such  krK»wledge  and  understanding  are  cer- 
tainly acquired  more  fully  and  more  easily  by  those  who, 
to  integrity  of  life  and  study  of  the  faith,  join  a  mind  that 
has  been  disciplined  by  philosophical  culture.  Specially  is 
this  so  since  the  same  Vatican  Synod  teaches  that  we 
ought  to  seek  for  understanding  of  holy  dogmas  of  that 
kind  '  both  from  the  analogy  of  the  things  which  naturally 
are  known,  and  also  from  the  way  in  which  the  mysteries 
themselves  are  related  to  one  another,  and  also  to  the  Icist 
end  of  man.' 

Lastly,  it  pertains  to  philosophical  discipline  to  guard 
with  religious  care  all  truths  that  come  to  us  by  Divine 
tradition,  and  to  resist  those  who  dare  to  attack  them. 
Now,  as  regards  this  point,  the  praise  of  philosophy  is  great, 
in  that  it  is  reckoned  a  bulwark  of  the  faith,  and  as  a  strong 
defence  of  religion.  *  The  doctrine  of  our  Saviour,'  as 
Clement  of  Alexandria  bears  witness,  *  is  indeed  perfect  in 
itself,  and  has  need  of  nothing,  forasmuch  as  it  is  the  power 
and  the  wisdom  of  God.  But  Greek  philosophy,  though  it 
does  not  by  its  approach  make  the  truth  more  powerful, 
has  yet  been  called  a  fit  hedge  and  ditch  for  the  vineyard, 
because  it  weakens  the  arguments  of  sophists  against  the 
truth,  and  wards  off  the  crafty  tricks  of  those  by  whom  the 
truth  is  attacked.' 

In  fact,  as  the  enemies  of  the  Catholic  name  borrow  their 
warlike  preparations  from  philosophic  method,  when  they 
begin  their  attacks  on  religion,  so  the  defenders  of  the  science 
of  God  borrow  many  weapons  from  the  stores  of  philosophy, 
by  which  to  defend  the  dogmas  of  revelation.  Again,  we 
must  count  it  no  small  victory  for  the  Christian  Faith,  that 
human  reason  powerfully  and  promptly  wards  off  those  very 
weapons  of  the  enemy  which  have  been  got  together  by  the 
skill  of  the  same  human  reason  for  purposes  of  harm. 
St.  Jerome,  writing  to  Magnus,  shows  how  the  Apostle  of 
the  Gentiles  himself  adopted  this  kind  of  argument.  '  Paul, 
the  leader  of  the  Christian  army  and  the  unanswered  speaker. 


kvi  THE  "  SUMMA  THEOLOGICA  '- 

pleading  a  cause  for  Christ,  turns  skilfully  even  a  chance 
inscription  into  an  argument  for  the  faith.  From  the  true 
David  he  had  learnt  indeed  how  to  pluck  the  weapon  from 
the  hands  of  his  enemies,  and  how  to  cut  off  the  head  of 
Goliath  in  his  greatest  pride  with  his  own  sword.' 

Nay,  more  ;  the  Church  herself  not  only  advises  Christian 
teachers,  but  commands  them  to  draw  this  safeguard  from 
philosophy.  For  the  fifth  Lateran  Council  decreed  that 
*  every  assertion  contrary  to  a  truth  of  enlightened  faith  is 
altogether  false,  because  the  truth  cannot  possibly  contra- 
dict the  truth ':  and  then  it  commands  doctors  of  philo- 
sophy to  apply  themselves  studiously  to  the  refutation  of 
fallacious  arguments ;  for  St.  Augustine  says :  '  If  any 
reason  be  given  against  the  authority  of  the  Holy  Scrip- 
tures, then,  however  subtle  it  may  be,  it  deceives  by  its 
likeness  to  the  truth  ;  for  true  it  cannot  possibly  be.' 

But  if  philosophy  has  to  be  found  equal  to  the  work  of 
bringing  forth  such  precious  fruits  as  We  have  mentioned, 
it  must,  above  everything,  take  care  never  to  wander  from 
the  path  trodden  by  the  venerable  antiquity  of  the  Fathers, 
and  approved  in  the  Vatican  Synod  by  the  solemn  suffrage 
of  authority.  It  is  plainly  seen  that  we  must  accept  many 
truths  in  the  supernatural  order  which  far  surpass  the  power 
of  any  intellect.  The  human  reason,  therefore,  conscious 
of  its  own  weakness,  must  not  dare  to  handle  things  greater 
than  itself  ;  nor  to  deny  these  truths.  Again,  it  must  not 
measure  them  by  its  own  strength,  or  interpret  them  at  its 
own  will.  Rather  let  it  receive  them  in  the  fulness  and 
humility  of  Faith  ;  reckoning  this  its  greatest  honour,  that 
by  the  goodness  of  God  it  is  allowed  as  a  handmaid  and 
servant  to  be  busied  about  heavenly  doctrines,  and  in  a 
certain  measure  to  reach  them. 

In  those  heads  of  doctrine,  however,  which  the  human 
understanding  naturally  can  take  in,  it  is  clearly  just  that 
philosophy  should  use  its  own  method,  its  own  principles, 
and  its  own  arguments  ;  yet  not  so  as  to  seem  to  draw  itself 
away  with  audacity  from  the  authority  of  God.  So,  also, 
when  it  is  plain  that  things  known  to  us  by  revelation  are 


ENCYCLICAL  OF  LEO  XIIL  xvij 

most  certainly  true,  and  that  the  arguments  brought  against 
the  Faith  are  not  in  accord  with  right  reason,  the  CathoHc 
philosopher  should  bear  in  mind  that  he  will  violate  the 
rights  both  of  Faith  and  reason,  if  he  embrace  any  conclusion 
which  he  understands  to  be  contrary  to  revealed  doctrine. 

We  know  indeed  that  there  are  to  be  found  men  who, 
exalting  too  highly  the  powers  of  human  nature,  contend 
that  the  understanding  of  man  falls  from  its  native  dignity 
when  it  becomes  subject  to  Divine  authority,  and  that  being 
thus  bound,  as  it  were,  in  a  yoke  of  slavery,  it  is  greatly 
retarded  and  hindered  from  reaching  the  heights  of  truth 
and  excellence.  Such  teaching  as  that  is  full  of  error  and 
falsehood.  The  end  of  it  is  that  men,  in  the  height  of  folly 
and  sinful  thanklessness,  reject  all  higher  truths.  They 
deliberately  cast  away  the  Divine  blessings  of  faith,  from 
which  the  streams  of  all  good  flow,  even  to  civil  society. 
Now,  the  mind  of  man  is  shut  up  and  held  in  certain  bounds, 
and  narrow  enough  those  boundaries  are.  The  consequence 
is  that  it  falls  into  many  mistakes  and  is  ignorant  of  many 
things.  On  the  other  hand,  the  Christian  Faith,  resting  as 
it  does  on  the  authority  of  God,  is  the  certain  teacher  of 
truth.  He  who  follows  this  guidance  is  neither  entangled 
in  the  nets  of  error  nor  tossed  about  on  the  waves  of  doubt. 
Hence  the  best  philosophers  are  they  who  join  philosophical 
study  with  the  obedience  of  the  Christian  Faith.  Then  the 
brightness  of  Christian  truths  falls  on  the  mind,  and  by  that 
brightness  the  understanding  itself  is  helped.  This  takes 
nothing  from  the  dignity  of  the  reason  ;  nay,  rather,  it  adds 
to  the  reason  a  great  deal  of  grandeur  and  subtlety  and 
strength. 

Worthily  and  most  fruitfully  do  we  use  the  keenness  of 
the  understanding  when  we  set  ourselves  to  refute  opinions 
against  the  Faith,  and  to  prove  those  things  which  agree 
with  it.  For  in  disproving  errors  we  ascertain  their  causes, 
and  then  show  the  falsity  of  the  arguments  by  which  they 
are  bolstered  up  ;  while  in  proving  truths  we  use  the  force 
of  the  reasons  by  which  they  are  demonstrated  with  cer- 
tainty, and  by  which  all  prudent  men  are  persuaded.     If, 


xviii  THE  "  SUMMA  THEOLOGICA  " 

then,  anyone  deny  that  the  riches  of  the  mmd  are  increased 
and  its  powers  extended  by  studies  and  arguments  such  as 
these,  he  must  of  necessity  contend  absurdly  that  the  dis- 
crimination of  truth  and  falsehood  does  not  in  any  way 
help  towards  intellectual  advancement.  Rightly,  therefore, 
does  the  Vatican  Synod  mention  in  the  following  words  the 
great  benefits  which  are  received  by  Faith  from  reason  : 
'  Faith  frees  the  reason  from  error,  and  guards  it,  and 
instructs  it  with  a  manifold  knowledge.'  If,  then,  man 
were  wise,  he  would  not  blame  Faith  as  being  hostile  to 
reason  and  natural  truths.  Rather  he  would  give  hearty 
thanks  to  God  and  rejoice  greatly  that,  among  so  many 
causes  of  ignorance  and  in  the  midst  of  such  floods  of  error, 
the  most  holy  Faith  shines  brightly  on  him  ;  for,  like  a 
friendly  star,  that  Faith  points  out  to  him  the  harbour  of 
truth,  so  that  he  can  have  no  fear  of  going  out  of  his 
course. 

If,  then.  Venerable  Brothers,  you  look  back  at  the  history 
of  philosophy,  you  will  see  that  all  the  words  which  We  have 
spoken  are  approved  by  the  facts.  Certainly,  among  the 
ancient  philosophers,  living  without  the  Faith,  they  who 
were  reckoned  the  wisest  erred  most  harmfully  in  many 
things.  Though  they  taught  the  truth  about  some  things, 
yet  you  know  how  often  they  taught  that  which  was  false 
and  absurd.  You  know  how  many  uncertain  things  and 
doubtful  things  they  handed  down  about  the  true  nature 
of  the  Godhead,  the  first  beginning  of  creation,  the  govern- 
ment of  the  world,  God's  knowledge  of  the  future,  the  cause 
and  principle  of  evil,  the  last  end  of  man,  everlasting  beati- 
tude, virtues  and  vices,  as  also  about  other  subjects,  of 
which  a  true  and  certain  knowledge  is  above  everything 
necessary  for  man. 

On  the  other  hand,  the  first  Fathers  and  Doctors  of  the 
Church  understood  clearly  from  the  counsel  of  the  will  of 
God  that  the  restorer  of  human  knowledge  is  Christ,  who 
is  the  *  power  of  God  and  the  wisdom  of  God,'  and  *  in 
whom  are  hidden  all  the  treasures  of  wisdom  and  know- 
ledge.'    They  undertook  to  examine  thoroughly  the  books 


ENCYCLICAL  OF  LEO  XIII.  xix 

of  these  wise  men  of  old,  and  to  compare  their  opinions  with 
the  teaching  of  Revelation.  With  prudent  choice  they 
accepted  all  the  true  words  and  wise  thoughts  with  which 
they  met ;  but  the  rest  they  either  set  right  or  cast  utterly 
away.  As  God,  in  His  careful  foresight  for  the  defence  of 
His  Church  against  the  rage  of  tyrants,  raised  up  the 
martyrs,  very  strong  and  lavish  of  their  mighty  souls  ;  so 
against  philosophers,  falsely  so  called,  and  against  heretics. 
He  raised  up  men  great  in  wisdom  to  defend  even  by  the 
help  of  human  reason  the  treasure  of  revealed  truth.  From 
the  very  beginning  of  the  Church,  indeed.  Catholic  doctrine 
has  found  enemies  most  hostile  to  it,  who  have  derided  the 
dogmas  and  teachings  of  Christians.  They  have  laid  down 
such  doctrines  as  these  :  That  there  are  many  gods  ;  that 
the  matter  of  which  the  world  is  made  has  neither  beginning 
nor  cause  ;  that  the  course  of  events  is  governed  by  a  certain 
blind  force  and  inevitable  necessity  ;  and  that  it  is  not  ruled 
by  the  counsel  of  the  providence  of  God.  Wise  men,  whom 
we  call  Apologists,  have  in  due  course  attacked  these 
teachers  of  insane  doctrine,  and,  with  Faith  for  their  guide, 
have  drawn  arguments  from  human  wisdom  itself.  They 
have  in  this  way  proved  that  one  God,  highest  in  every  kind 
of  perfection,  is  to  be  worshipped  ;  that  all  things  have  been 
made  out  of  nothing  by  His  almighty  power  ;  that  they  are 
all  sustained  by  His  wisdom  ;  and  that  each  one  is  directed 
and  moved  towards  its  own  end. 

Among  these,  St.  Justin  MsLTtyv  claims  for  himself  the 
first  place.  Having  frequented  the  most  celebrated  schools 
of  learning  among  the  Greeks  that  he  might  try  what  they 
were,  he  learned,  as  he  himself  acknowledges,  that  he  could 
drink  in  the  truth  with  full  mouth  only  from  revealed  doc- 
trines. These  he  embraced  with  all  the  eagerness  of  his 
soul ;  stripped  off  the  calumnies  that  hung  round  them  ; 
defended  them  vigorously  and  fully  before  the  Roman 
Emperors  ;  and  reconciled  with  them  many  sayings  of  the 
Greek  philosophers.  In  that  time  the  same  work  was  also 
done  exceedingly  well  by  Quadratus,  Aristides,  Hermias, 
and  Atlienagoras.     In  the  same  cause  glory  not  less  than 


XX  THE  "  SUMMA  THEOLOGICA  " 

theirs  was  gained  by  the  Bishop  of  Lyons,  Irenseus,  the 
invincible  martyr.  He  refuted  with  power  the  wicked 
teaching  of  the  Easterns,  scattered  as  it  was  by  the  help 
of  the  Gnostics  throughout  the  bounds  of  the  Roman 
Empire.  St.  Jerome  says  of  him  :  *  He  explained  .  .  . 
the  beginnings  of  heresies  one  by  one,  and  pointed  out  from 
what  fountains  of  the  philosophers  they  flowed.' 

Again,  there  is  no  one  who  does  not  know  the  disputa- 
tions of  Clement  of  Alexandria,  which  the  same  St.  Jerome 
thus  mentions  with  honour  :  '  Is  there  anything  that  is 
not  learned  in  them  ?  Is  there  anything  not  drawn  from 
the  depth  of  philosophy  ?'  He  himself  also  wrote  books 
of  an  incredible  variety,  which  are  of  the  greatest  use  in 
building  up  a  history  of  philosophy,  in  rightly  exercising 
the  art  of  dialectics,  and  in  establishing  the  harmony  that 
exists  between  reason  and  faith.  Origen  followed  him, 
renowned  among  the  teachers  of  the  Alexandrine  school, 
and  deeply  learned  in  the  doctrine  of  the  Greeks  and  the 
Easterns.  He  wrote  a  very  great  number  of  books,  and 
spent  much  labour  upon  them.  Wondrously,  just  at  the 
right  time,  they  explained  the  Holy  Scriptures,  and  threw 
light  on  our  sacred  dogmas.  It  is  true  that  these  books, 
at  least  in  their  present  state,  are  not  altogether  free  from 
errors  ;  yet  they  embrace  great  force  of  teaching,  by  which 
natural  truths  are  increased  in  number  and  in  strength. 
Tertullian,  too,  fights  against  the  heretics  by  the  authority 
of  Scripture.  Then  changing  his  weapons,  he  fights  against 
the  philosophers  with  arguments  of  philosophy.  With  so 
much  acuteness  and  learning  does  he  refute  them,  that  he 
answers  them  openly  and  confidently  :  '  Neither  about 
science  nor  about  learning  are  we,  as  you  think,  on  an 
equal  footing.'  Amobius  also  in  his  books  against  the 
Gentiles,  and  Lactantius  in  his  Institutions  especially,  strive 
earnestly  with  like  eloquence  and  strength  to  persuade  men 
to  accept  the  dogmas  and  commands  of  Catholic  wisdom. 
They  do  not  overthrow  philosophy,  according  to  the  way 
of  the  Academy  ;  but  partly  by  their  own  weapons,  and 
partly  by  weapons  taken  from  the  agreement  of  philosophers 


ENCYCLICAL  OF  LEO  XIIL  xxi 

among  themselves,  they  convince  them.  The  great 
Athanasius  and  Chrysostom,  first  of  preachers,  have  left 
writings  about  the  soul  of  man,  about  the  Attributes  of 
God,  and  other  questions  of  the  greatest  moment.  These 
in  the  judgment  of  all  are  so  excellent  that  it  seems  as  if 
scarcely  anything  could  be  added  to  their  subtlety  and 
exhaustiveness.  Not  to  be  too  prolix  in  mentioning  them 
one  by  one,  we  add  to  the  number  of  these  most  illustrious 
men  of  whom  we  have  spoken  the  great  Basil  and  the  two 
Gregories.  From  Athens,  then  the  home  of  the  highest 
culture,  they  went  forth  equipped  with  the  panoply  of 
philosophy.  Having  acquired  all  their  riches  of  learning 
by  most  ardent  study,  they  used  them  to  refute  the  heretic, 
and  to  build  up  the  faithful. 

But  it  is  Augustine  who  seems  to  have  borne  away  the 
palm  from  all.  With  a  towering  intellect,  and  a  mind  full 
to  overflowing  of  sacred  and  profane  learning,  he  fought 
resolutely  against  all  the  errors  of  his  age,  with  the  greatest 
faith  and  equal  knowledge.  What  teaching  of  philosophy 
did  he  pass  over  ?  Nay,  what  was  there  into  which  he  did 
not  search  thoroughly  ?  Did  he  not  do  this  when  he  was 
explaining  to  believers  the  deepest  mysteries  of  the  Faith, 
and  defending  them  against  the  furious  attacks  of  the 
adversaries  ?  or  when,  after  destroying  the  fictions  of 
Academics  and  Manichseans,  he  made  safe  the  foundations 
of  human  knowledge  and  their  certainty,  searching  out  also 
to  the  furthest  point  the  reason  and  origin  and  causes  of 
those  evils  by  which  man  is  oppressed  ?  With  what  copious- 
ness and  with  what  subtlety  did  he  write  about  the  angels,  and 
the  soul,  and  the  human  mind  ;  about  the  will  and  free-will ; 
about  religion  and  the  blessed  life  ;  about  time  and  eternity  ; 
about  the  nature  of  all  changeable  bodies  !  Afterwards, 
among  the  Easterns,  John  of  Damascus  followed  in  the 
footsteps  of  Basil  and  Gregory  Nazianzen  ;  while  in  the 
West,  Boethius  and  Anselm,  setting  forth  the  doctrines  of 
Augustine,  greatly  enriched  the  domain  of  philosophy. 

Then  the  Doctors  of  the  Middle  Ages,  whom  we  call 
Scholastics,   set   themselves  to  do   a  work  of  very  great 


xxii  THE  "  SUMMA  THEOLOGICA  " 

magnitude.  There  are  rich  and  fruitful  crops  of  doctrine 
scattered  everywhere  in  the  mighty  volumes  of  the  Holy 
Fathers.  The  aim  of  the  Scholastics  was  to  gather  these 
together  diligently,  and  to  store  them  up,  as  it  were,  in 
one  place,  for  the  use  and  convenience  of  those  that  come 
after. 

What  the  origin  of  the  Scholastic  discipline  was,  what 
were  also  its  characteristics  and  its  value,  it  will  be  well. 
Venerable  Brothers,  to  set  forth  more  fully  here  in  the 
words  of  a  man  of  the  greatest  wisdom — our  predecessor 
Sixtus  V. :  'By  the  Divine  gift  of  Him, Who  alone  gives  the 
spirit  of  knowledge  and  wisdom  and  understanding,  and 
Who,  through  the  ages,  according  to  her  needs,  enriches  His 
Church  with  new  gifts,  and  surrounds  her  with  new  safe- 
guards, our  ancestors,  being  men  exceedingly  wise,  developed 
the  study  of  Scholastic  Theology.  There  were  especially 
two  glorious  Doctors,  teachers  of  this  famous  science — that 
is,  the  angelic  St.  Thomas,  and  the  seraphic  St.  Bonaventure. 
With  surpassing  abilities,  with  ceaseless  study,  with  labor- 
ious toil  and  long  watchings,  they  worked  it  out  and  adorned 
it.  They  arranged  it  in  the  very  best  way,  unfolded  it 
brilliantly  in  many  methods,  and  then  handed  it  on  to  their 
successors.' 

The  knowledge  and  the  exercise  of  this  science  of  salvation 
have  certainly  always  brought  the  very  greatest  help  to  the 
Church  ;  whether  it  be  for  the  right  understanding  and 
interpretation  of  Scripture,  or  for  reading  and  expounding 
the  Fathers  with  greater  safety  and  profit,  or  for  laying 
bare  and  answering  different  errors  and  heresies.  This 
doctrine  flows  from  the  brimming  fountain  of  the  Sacred 
Scriptures,  of  the  Supreme  Pontiffs,  and  of  Holy  Fathers 
and  Councils.  Now,  indeed,  in  these  last  days,  it  is  in  the 
highest  degree  necessary  to  refute  heresies  and  confirm  the 
dogmas  of  the  Catholic  faith.  For  now  have  come  those 
dangerous  times  of  which  the  Apostle  speaks.  Now  men, 
blasphemous,  proud,  deceivers,  go  from  bad  to  worse,  wan- 
dering from  the  truth  themselves  and  leading  others  into 
erj-or.     These   words   might   seem   to   embrace    only   the 


ENCYCLICAL  OF  LEO  XIIL  xxiii 

Scholastic  Theology ;  but  it  is  plain  that  they  are  also  to  be 
taken  in  reference  to  philosophy  and  its  praise. 

Scholastic  Theology  has  splendid  gifts,  which  make  it 
very  formidable  to  enemies  of  the  truth  ;  as  the  same  Pontiff 
tells  us.  '  It  has,'  he  ,says,  *  an  apt  coherence  of  facts  and 
causes,  connected  with  one  another  ;  an  order  and  arrange- 
ment, like  soldiers  drawn  up  in  battle  array  ;  definitions 
and  distinctions  very  lucid  ;  unanswerableness  of  argument 
and  acute  disputations.  By  these  the  light  is  divided  from 
the  darkness,  and  truth  from  falsehood.  The  lies  of  heretics, 
wrapped  up  in  many  wiles  and  fallacies,  being  stripped  of 
their  coverings,  are  bared  and  laid  open.*  But  these  great 
and  wondrous  gifts  can  only  be  found  in  a  right  use  of  that 
philosophy  which  the  masters  of  Scholasticism,  of  set  purpose 
and  with  wise  counsel,  were  everywhere  accustomed  to  use 
even  in  their  theological  disputations.' 

Moreover,  it  is  the  proper  and  singular  gift  of  Scholastic 
theologians  to  bind  together  human  knowledge  and  Divine 
knowledge  in  the  very  closest  bonds.  For  this  reason,  truly 
the  theology  in  which  they  excelled  could  never  have  gained 
so  much  honour  and  praise  from  the  judgment  of  men  as  it 
did,  if  they  had  used  a  system  of  philosophy  which  was 
maimed,  or  imperfect,  or  shallow. 

Now  far  above  all  other  Scholastic  Doctors  towers  Thomas 
Aquinas,  their  master  and  prince.  Cajetan  says  truly  of 
him  :  *  So  great  was  his  veneration  for  the  ancient  and 
sacred  Doctors  that  he  may  be  said  to  have  gained  a  perfect 
understanding  of  them  all.'  Thomas  gathered  together 
their  doctrines  like  the  scattered  limbs  of  a  body,  and 
moulded  them  into  a  whole.  He  arranged  them  in  so 
wonderful  an  order,  and  increased  them  with  such  great 
additions,  that  rightly  and  deservedly  he  is  reckoned  a 
singular  safeguard  and  glory  of  the  Catholic  Churchr.  His 
intellect  was  docile  and  subtle  ;  his  memory  was  ready  and 
tenacious  ;  his  life  was  most  holy  ;  and  he  loved  the  truth 
alone.  Greatly  enriched  as  he  was  with  the  science  of  God 
and  the  science  of  man,  he  is  likened  to  the  sun  ;  for  he 
warmed  the  whole  earth  with  the  fire  of  his  holiness,  and 


xxiv  THE  "  SUMMA  THEOLOGICA  " 

filled  the  whole  earth  with  the  splendour  of  his  teaching. 
There  is  no  part  of  philosophy  which  he  did  not  handle  with 
acuteness  and  solidity.  He  wrote  about  the  laws  of  reason- 
ing ;  about  God  and  incorporeal  substances  ;  about  man  and 
other  things  of  sense  ;  and  about  human  acts  and  their 
principles.  What  is  more,  he  wrote  on  these  subjects  in 
such  a  way  that  in  him  not  one  of  the  following  perfections 
is  wanting  :  a  full  selection  of  subjects  ;  a  beautiful  arrange- 
ment of  their  divisions  ;  the  best  method  of  treating  them  ; 
certainty  of  principles  ;  strength  of  argument ;  perspicuity 
and  propriety  in  language  ;  and  the  power  of  explaining 
deep  mysteries. 

Beside  these  questions  and  the  like,  the  Angelic  Doctor, 
in  his  speculations,  drew  certain  philosophical  conclusions 
as  to  the  reasons  and  principles  of  created  things.  These 
conclusions  have  the  very  widest  reach,  and  contain,  as  it 
were,  in  their  bosom  the  seeds  of  truths  wellnigh  infinite 
in  number.  These  have  to  be  unfolded  with  most  abundant 
fruits  in  their  own  time  by  the  teachers  who  come  after 
him.  As  he  used  his  method  of  philosophizing,  not  only 
in  teaching  the  truth,  but  also  in  refuting  error,  he  has  gained 
this  prerogative  for  himself.  With  his  own  hand  he  van- 
quished all  errors  of  ancient  times  ;  and  still  he  supplies  an 
armoury  of  weapons  which  brings  us  certain  victory  in  the 
conflict  with  falsehoods  ever  springing  up  in  the  course  of 
years. 

Moreover,  carefully  distinguishing  reason  from  Faith,  as 
is  right,  and  yet  joining  them  together  in  a  harmony  of 
friendship,  he  so  guarded  the  rights  of  each,  and  so  watched 
over  the  dignity  of  each,  that,  as  far  as  man  is  concerned, 
reason  can  now  hardly  rise  higher  than  she  rose,  borne  up 
in  the  flight  of  Thomas  ;  and  Faith  can  hardly  gain  more 
helps  and  greater  helps  from  reason  than  those  which 
Thomas  gave  her. 

For  these  causes,  especially  in  former  days,  men  of  the 
greatest  learning  and  worthy  of  the  highest  praise  both  in 
theology  and  philosophy,  having  sought  out  with  incredible 
diligence   the   immortal   writings   of  Thomas,   surrendered 


ENCYCLICAL  OF  LEO  XIIL  xxv 

themselves  to  his  angelic  wisdom,  not  so  much  to  be  taught 
by  his  words,  as  to  be  altogether  nourished  by  them.  It  is 
plain  also  that  nearly  all  founders  and  lawgivers  of  religious 
Orders  have  bidden  their  children  study  the  doctrines  of 
Thomas,  and  very  religiously  adhere  to  them,  giving  a 
caution  that  it  will  be  allowed  to  none  to  deviate  ever  so 
little  from  the  footsteps  of  so  great  a  man.  To  pass  by  the 
Dominican  family  which,  as  it  were,  by  a  right  of  its  own, 
glories  in  this  greatest  of  teachers,  the  statutes  of  each  Order 
testify  that  Benedictines,  Carmelites,  Augustinians,  the 
Society  of  Jesus,  and  many  other  holy  Orders,  are  bound 
by  this  law. 

Now  our  mind  flies  with  great  delight  to  those  very 
celebrated  universities  and  schools  which  formerly  flourished 
in  Europe :  such  as  Paris,  Salamanca,  Alcala,  Douai, 
Toulouse,  Louvain,  Padua,  Bologna,  Naples,  Coimbra,  and 
very  many  others.  No  one  is  ignorant  that  the  reputation 
of  these  imiversities  grew  by  age  ;  that  their  opinions  were 
asked  when  weighty  issues  were  at  stake  ;  and  that  those 
opinions  had  great  influence  everywhere.  But  it  is  also 
well  known  that,  in  those  illustrious  abodes  of  human 
learning,  Thomas  reigned  as  a  ruler  in  his  own  kingdom. 
The  minds  of  all,  both  teachers  and  hearers,  with  wondrous 
consent  found  rest  in  the  guidance  and  authority  of  one 
Angelic  Doctor. 

But  further — and  this  is  of  greater  importance — the 
Roman  Pontiffs,  our  predecessors,  bore  witness  to  the 
wisdom  of  Thomas  x\quinas  with  praises  singularly  strong, 
and  with  most  abundant  testimonies.  Clement  VI., 
Nicholas  V.,  Benedict  XIIL,  and  others,  testify  that  the 
whole  Church  was  enlightened  by  his  admirable  teaching. 
Pius  V.  acknowledges  that  heresies  are  confounded  and 
exposed  and  scattered  by  his  doctrine,  and  that  by  it  the 
whole  world  is  daily  freed  from  pestilent  errors.  Others, 
with  Clement  XI I. ,  say  that  most  fruitful  blessings  have 
flowed  from  his  writings  on  the  whole  Church.  They  affirm 
also  that  the  same  honour  has  to  be  given  to  him  as  to  the 
greatest  Doctors  of  the  Church,  such  as  Gregory  and  Am- 


xxvi  THE  "  SUMMA  THEOLOGICA  " 

brose,  and  Augustine  and  Jerome.  Others  did  not  hesitate 
to  set  forth  St.  Thomas  as  a  standard  and  teacher  to  uni- 
versities and  great  schools  of  learning,  saying  that  they 
might  safely  follow  him.  On  this  point  the  words  of  Blessed 
Urban  V.  to  the  University  of  Toulouse  seem  to  be  most 
worthy  of  mention  :  *  It  is  our  will,  and  by  the  authority 
of  these  letters  we  enjoin  on  you,  that  you  follow  the  doctrine 
of  Blessed  Thomas  as  true  and  Catholic,  and  strive  to  unfold 
it  with  your  whole  strength.*  This  example  of  Urban  was 
followed  by  Innocent  XII.  in  the  University  of  Louvain, 
and  by  Benedict  XIV.  in  the  Dionysian  College  of  Granada. 
To  these  judgments  of  the  Pontiffs  about  Thomas  there  is 
added,  as  a  crown,  the  testimony  of  Innocent  VI.:  'His 
doctrine  above  all  other  doctrine,  with  the  one  exception 
of  the  Holy  Scriptures,  has  such  a  propriety  of  words,  such 
a  method  of  explanation,  such  a  truth  of  opinions,  that  no 
one  who  holds  it  will  ever  be  found  to  have  strayed  from  the 
path  of  truth  ;  whereas  anyone  who  has  attacked  it  has 
always  been  suspected  as  to  the  truth. 

Moreover,  (Ecumenical  Councils,  made  glorious  by  the 
flower  of  wisdom  gathered  from  the  whole  world,  always 
strove  with  great  care  to  give  singular  honour  to  Thomas 
Aquinas.  In  the  Councils  of  Lyons,  of  Vienne,  of  Florence, 
of  the  Vatican,  you  may  say  that  Thomas  was  present  at 
the  deliberations  and  decrees  of  the  Fathers,  and  almost 
that  he  presided  at  them,  contending  against  the  errors  of 
Greeks  and  heretics  and  rationalists,  with  a  power  from 
which  there  was  no  escape,  and  with  a  most  auspicious 
result. 

But  we  now  come  to  the  greatest  glory  of  Thomas — a 
glory  which  is  altogether  his  own,  and  shared  with  no  other 
Catholic  Doctor.  In  the  midst  of  the  Council  of  Trent,  the 
assembled  Fathers  so  willing  it,  the  Summu  of  Thomas 
Aquinas  lay  open  on  the  altar,  with  the  Holy  Scriptures  and 
the  decrees  of  the  Supreme  Pontiffs,  that  from  it  might  be 
sought  counsel  and  reasons  and  answers. 

Lastly,  another  crown  seems  to  have  been  kept  for  this 
peerless  man — that  is,  the  way  in  which  he  extorts  homage, 


ENCYCLICAL  OF  LEO  XIIL  xxvii 

praise,  and  admiration  even  from  the  enemies  of  the  Catholic 
name.  It  is  well  known  that  there  have  not  been  wanting 
heresiarchs  who  openly  said  that,  if  the  doctrine  of  Thomas 
Aquinas  could  only  be  got  rid  of,  they  could  *  easily  give 
battle  to  other  Catholic  Doctors,  and  overcome  them,  and 
so  scatter  the  Church.'  A  vain  hope  indeed,  but  no  vain 
testimony  ! 

For  these  reasons,  Venerable  Brothers,  so  often  as  We 
look  at  the  goodness,  the  force,  and  the  exceedingly  great 
usefulness  of  that  philosophical  doctrine  in  which  our  fathers 
took  such  delight,  We  judge  that  it  has  been  rashly  done 
when  this  doctrine  has  not  always,  and  everywhere,  been 
held  in  its  own  rightful  honour.  Especially  do  We  judge 
this  to  be  the  case,  since  it  is  plain  that  long  use  and  the 
judgment  of  the  greatest  men,  and,  what  is  more  than  all, 
the  consent  of  the  Church,  have  favoured  the  Scholastic 
method.  Here  and  there  a  certain  new  kind  of  philosophy 
has  taken  the  place  of  the  old  doctrine ;  and  because  of  this, 
men  have  not  gathered  those  desirable  and  wholesome  fruits 
which  the  Church  and  civil  society  itself  could  have  wished. 
The  aggressive  innovators  of  the  sixteenth  century  have 
not  hesitated  to  philosophize  without  any  regard  whatever 
to  the  Faith,  asking,  and  conceding  in  return,  the  right  to 
invent  anything  that  they  can  think  of,  and  anything  that 
they  please.  From  this  it  quickly  followed,  of  course,  that 
systems  of  philosophy  were  multiplied  beyond  all  reason, 
and  that  there  sprang  up  conflicting  opinions  and  diverse 
opinions  even  about  some  of  the  chief  things  which  are 
within  human  knowledge.  From  a  multitude  of  opinions 
men  very  often  pass  to  uncertainty  and  doubt ;  while  there 
is  no  one  who  does  not  see  how  easily  their  minds  glide  from 
doubt  into  error. 

But,  since  man  is  drawn  by  imitation,  we  have  seen  these 
novelties  lay  hold  of  the  minds  of  some  Catholic  philosophers, 
who,  undervaluing  the  inheritance  of  ancient  wisdom,  have 
chosen  rather  to  invent  new  things  than  to  extend  and 
perfect  the  old  by  new  truths,  and  that  certainly  with  unwise 
counsel,  and  not  without  loss  to  science  ;  for  such  a  manifold 


xxviii  THE  "  SUMMA  THEOLOGICA  " 

kind  of  doctrine  has  only  a  shifting  foundation,  resting  as 
it  does  on  the  authority  and  will  of  individual  teachers. 
For  this  reason  it  does  not  make  philosophy  firm  and  strong 
and  solid,  like  the  old  philosophy,  but,  on  the  contrary, 
makes  it  weak  and  shallow. 

When  We  say  this,  however.  We  do  not  condemn  those 
learned  and  able  men  who  bring  their  industry  and  their 
knowledge,  and  the  riches  of  new  discoveries,  to  the  aid  of 
philosophy  ;  for  We  clearly  see  that  such  a  course  tends  to 
the  increase  of  learning.  But  with  great  care  we  must 
guard  against  spending  the  whole  of  our  attention,  or  even 
the  chief  part  of  it,  on  such  studies  as  these,  and  on  such 
instruction. 

Let  the  same  judgment  be  formed  about  Sacred  Theology. 
This  may  well  be  aided  arid  illustrated  by  many  helps  of 
erudition  ;  but  it  is  altogether  necessary  that  it  should  be 
treated  in  the  weighty  manner  of  the  Scholastics,  in  order 
that  it  may  continue  to  be  the  '  unassailable  bulwark  of  the 
faith,'  by  the  forces  of  reason  and  revelation  thus  united 
in  it. 

Students  of  philosophy,  therefore,  not  a  few,  giving  their 
minds  lately  to  the  task  of  setting  philosophy  on  a  surer 
footing,  have  done  their  utmost,  and  are  doing  their  utmost, 
to  restore  to  its  place  the  glorious  teaching  of  Thomas 
Aquinas,  and  to  win  for  it  again  its  former  renown. 

That  many  of  your  order.  Venerable  Brothers,  are  with 
like  will  following  promptly  and  cheerfully  in  the  same 
path,  We  know  to  the  great  gladness  of  Our  heart.  While 
We  praise  these  much.  We  exhort  them  to  go  on  in  the  way 
that  they  have  begun.  To  the  rest  of  you,  one  by  one, 
We  give  this  word  of  counsel :  there  is  nothing  which  We 
have  longer  wished  for  and  desired  than  that  you  should 
give  largely  and  abundantly  to  youths  engaged  in  study 
the  pure  streams  of  wisdom  which  flow  from  the  Angelic 
Doctor  as  from  a  perennial  and  copious  spring. 

Our  reasons  for  wishing  this  so  earnestly  as  We  do  are 
many. 

First,   in  our  times,  the   Christian  Faith   is  commonly 


ENCYCLICAL  OF  LEO  XIIL  xxix 

opposed  by  the  wiles  and  craft  of  a  certain  deceitful  kind 
of  wisdom.  All  young  men,  therefore,  and  especially  those 
who  are  growing  up  as  the  hope  of  the  Church,  ought  to  be 
fed  with  healthful  and  strong  food  of  doctrine.  Thus, 
being  mighty  in  strength,  and  possessing  an  armoury  in 
which  all  needful  weapons  may  be  found,  they  will  learn  by 
experience  to  treat  the  cause  of  religion  with  power  and 
wisdom,  according  to  the  admonition  of  the  Apostle,  '  being 
ready  always  to  satisfy  everyone  that  asketh  you  a  reason 
of  that  hope  which  is  in  you ':  and  being  *  able  to  exhort  in 
sound  doctrine  and  to  convince  the  gainsayers.' 

Next,  there  are  many  who,  with  minds  alienated  from  the 
Faith,  hate  all  Catholic  teaching,  and  say  that  reason  alone 
is  their  teacher  and  guide.  To  heal  these  men  of  their  un- 
belief, and  to  bring  them  to  grace  and  the  Catholic  Faith, 
We  think  that  nothing,  after  the  supernatural  help  of  God, 
can  be  more  useful  in  these  days  than  the  solid  doctrine  of 
the  Fathers  and  the  Scholastics.  They  teach  firm  founda- 
tions of  Faith,  its  Divine  origin,  its  certain  truth,  the  argu- 
ments by  which  it  is  commended  to  men,  the  benefits  that 
it  has  conferred  on  the  himian  race,  and  its  perfect  harmony 
with  reason.  They  teach  all  such  truths  with  a  weight  of 
evidence  and  a  force  that  may  well  persuade  even  minds 
unwilling  and  hostile  in  the  highest  degree. 

Again,  we  all  see  the  great  dangers  which  threaten  family 
life,  and  even  civil  society  itself,  because  of  the  pestilence 
of  perverse  opinions.  Truly  all  civil  society  would  be 
much  more  tranquil  and  much  safer  if  healthier  teaching 
were  given  in  universities  and  schools  ;  a  doctrine  more  in 
unison  with  the  perpetual  teaching  office  {magisterium)  of 
the  Church,  such  as  is  contained  in  the  volumes  of  Thomas 
Aquinas.  He  disputes  about  the  true  nature  of  liberty, 
which,  in  these  days,  is  passing  into  lawlessness  ;  about  the 
Divine  origin  of  all  authority  ;  about  laws  and  their  binding 
force  ;  about  the  paternal  and  just  government  of  sovereign 
princes,  with  our  obedience  to  higher  powers,  and  the 
common  love  that  should  be  among  all.  The  words  of 
Thomas  about  these  things,  and  others  of  a  like  nature,  have 


XXX  THE  *'  SUMMA  THEOLOGICA  " 

the  greatest  strength,  indeed  a  resistless  strength,  to  over- 
throw the  principles  of  this  new  jurisprudence,  which  is 
manifestly  dangerous  to  the  peaceful  order  of  society  and 
to  public  safety. 

Lastly,  from  the  restoration  of  philosophical  teaching  as 
it  has  been  set  forth  by  Us,  all  human  sciences  ought  to  gather 
hope  of  improvement,  and  the  promise  of  a  very  great 
safeguard.  For  from  philosophy,  as  from  a  guiding  wisdom, 
the  beneficent  arts  have  hitherto  derived  a  healthy  method 
and  a  right  measure.  They  have,  moreover,  drunk  a  vital 
spirit  from  it  as  from  a  common  fountain  of  life.  It  is 
proved  by  fact  and  constant  experience  that  the  liberal  arts 
have  been  most  flourishing  when  the  honour  of  philosophy 
has  stood  inviolate,  and  when  its  judgment  has  been  held 
for  wisdom  :  but  that  they  have  lain  neglected  and  almost 
obliterated  when  declining  philosophy  has  been  enveloped 
in  errors  and  absurdities. 

Hence,  also,  the  physical  sciences,  which  now  are  held 
in  so  much  repute,  and  everywhere  draw  to  themselves  a 
singular  admiration,  because  of  the  many  wonderful  dis- 
coveries made  in  them,  would  not  only  take  no  harm  from 
a  restoration  of  the  philosophy  of  the  ancients,  but  would 
derive  great  protection  from  it.  For  the  fruitful  exercise 
and  increase  of  these  sciences  it  is  not  enough  that  we  con- 
sider facts  and  contemplate  Nature.  When  the  facts  are 
well  known  we  must  rise  higher,  and  give  our  thoughts  with 
great  care  to  understanding  the  nature  of  corporeal  things, 
as  well  as  to  the  investigation  of  the  laws  which  they  obey, 
and  of  the  principles  from  which  spring  their  order,  their 
unity  in  variety,  and  their  common  likeness  in  diversity. 
It  is  marvellous  what  power  and  light  and  help  are  given 
to  these  investigations  by  Scholastic  philosophy,  if  it  be 
wisely  used. 

On  this  point  it  is  well  to  call  one  thing  to  your  minds. 
It  is  only  by  the  highest  injustice  that  any  jealousy  of  the 
progress  and  increase  of  natural  sciences  is  laid,  as  a  fault,  at 
the  door  of  that  philosophy.  When  the  Scholastics,  following 
the  teaching  of  the  Holy  Fathers,  everywhere  taught  through- 


ENCYCLICAL  OF  LEO  XIIL  xxxi 

out  their  anthropology  that  the  human  understanding  can 
only  rise  to  the  knowledge  of  immaterial  things  by  things 
of  sense,  nothing  could  be  more  useful  for  the  philosopher 
than  to  investigate  carefully  the  secrets  of  Nature,  and  to 
be  conversant,  long  and  laboriously,  with  the  study  of 
physical  science.  Indeed,  they  themselves  prove  this  by 
their  works.  Thomas,  and  Blessed  Albert  the  Great, 
and  other  princes  of  the  Scholastics,  did  not  so  give  them- 
selves up  to  the  study  of  philosophy,  as  to  have  little  care 
for  the  knowledge  of  natural  things.  Nay,  on  this  matter 
there  are  not  a  few  of  their  words  and  discoveries  which 
modern  teachers  approve  and  acknowledge  to  be  in  harmony 
with  truth.  Besides,  in  this  very  age,  many  distinguished 
teachers  of  physical  sciences  openly  bear  witness  that  there 
is  no  contradiction,  truly  so  called,  between  the  certain  and 
proved  conclusions  of  recent  physics,  and  the  philosophical 
principles  of  the  Schools. 

We,  therefore,  while  We  declare  that  everything  wisely 
said  should  be  received  with  willing  and  glad  mind,  as  well 
as  everything  profitably  discovered  or  thought  out,  exhort 
all  of  you.  Venerable  Brothers,  with  the  greatest  earnestness 
to  restore  the  golden  wisdom  of  St.  Thomas,  and  to  spread 
it  as  far  as  you  can,  for  the  safety  and  glory  of  the  Catholic 
Faith,  for  the  good  of  society,  and  for  the  increase  of  all  the 
sciences.  We  say  the  wisdom  of  St.  Thomas ;  for  it  is  not 
by  any  means  in  our  mind  to  set  before  this  age,  as  a  stan- 
dard, those  things  which  may  have  been  inquired  into  by 
Scholastic  Doctors  with  too  great  subtlety  ;  or  anything 
taught  by  them  with  too  little  consideration,  not  agreeing 
with  the  investigations  of  a  later  age ;  or,  lastly,  anything 
that  is  not  probable. 

Let,  then,  teachers  carefully  chosen  by  you  do  their  best 
to  instil  the  doctrine  of  Thomas  Aquinas  into  the  minds  of 
their  hearers  ;  and  let  them  clearly  point  out  its  soliditv 
and  excellence  above  all  other  teaching.  Let  this  doctrine 
be  the  light  of  all  places  of  learning  which  you  may  have 
already  opened,  or  may  hereafter  open.  Let  it  be  used  for 
the  refutation  of  errors  that  are  gaining  groimd. 

I.  c

But  lest  the  false  should  be  drunk  instead  of  the  true  ;  oi 
lest  that  which  is  unwholesome  should  be  drunk  instead  of 
that  which  is  pure  ;  take  care  that  the  wisdom  of  Thomas 
be  drawn  from  his  own  fountain,  or  at  any  rate  from  those 
streams  which,  in  the  certain  and  unanimous  opinion  of 
learned  men,  yet  flow  whole  and  untainted,  inasmuch  as  they 
are  led  from  the  fountain  itself.  Take  care,  moreover,  that 
the  minds  of  the  young  be  kept  from  streams  which  are  said 
to  have  flowed  from  thence,  but  in  reality  have  been  fed 
by  unhealthy  waters  from  other  springs. 

Well  do  we  know  that  all  our  work  will  be  vain,  unless, 
Venerable  Brothers,  He  bless  our  common  efforts,  Who  in 
the  Divine  Scriptures  is  called  the  '  God  of  all  know- 
ledge.' By  those  same  Scriptures  we  are  warned,  that 
*  every  best  gift  and  every  perfect  gift  is  from  above,  coming 
down  from  the  Father  of  lights.'  Again,  *If  any  of  you 
want  wisdom,  let  him  ask  of  God,  who  giveth  to  all  men 
abundantly  and  upbraideth  not ;  and  it  shall  be  given  him.' 

In  this  matter,  then,  let  us  follow  the  example  of  the 
Angelic  Doctor,  who  never  began  to  read  or  to  write  without 
seeking  for  God's  help  by  prayer ;  and  who  in  simplicity 
acknowledged  that  all  his  learning  had  come  to  him,  not 
so  much  from  his  own  study  and  toil,  as  immediately  from 
God.  With  humble  and  united  prayer,  therefore,  let  us 
all  together  beseech  God  fervently  to  pour  out  the  spirit 
of  knowledge  and  understanding  on  the  sons  of  the  Church, 
and  to  open  their  minds  to  the  understanding  of  wisdom. 

Also,  that  we  may  receive  more  abundant  fruits  of  the 
goodness  of  God,  use  that  patronage  which  is  most  powerful 
with  Him ;  that  is,  the  patronage  of  the  Blessed  Virgin 
Mary,  who  is  called  the  Seat  of  Wisdom.  Secure  also,  as 
intercessors,  Blessed  Joseph,  the  pure  Spouse  of  the  Virgin  ; 
and  Peter  and  Paul,  the  chiefs  of  the  Apostles,  who  renewed 
the  whole  world  with  truth,  when  it  was  corrupted  by  the 
uncleanness  and  the  contagion  of  errors,  and  who  filled  it 
with  the  light  of  the  wisdom  which  is  from  Heaven. 

Lastly,  in  hope,  trusting  to  the  help  of  God  and  relying 
on  your  pastoral  zeal,  to  all  of  you.  Venerable  Brothers,  to 
all  the  clergy,  and  all  the  people  committed  to  the  care  of 


ENCYCLICAL  OF  LEO  XIIL  xxxiii 

each,  we  give,  with  great  love  in  the  Lord,  our  Apostolical 
blessing,  the  earnest  of  heavenly  gifts,  and  the  witness  of  our 
special  goodwill.

THE  NEW  CODEX  OF  CANON  LAW. 

Issued  by  Authority  of  Pope  Benedict  XV.,  1917. 

Canon  589:  Religious  who  have  already  studied  their 
humanities  should  devote  themselves  for  two  years  at  least 
to  philosophy  and  for  four  years  to  theology,  following  the 
teaching  of  S.  Thomas  (cf.  Canon  1366,  §  2)  in  accordance 
with  the  instructions  of  the  Holy  See. 

Canon  1366,  §  2 :  The  study  of  philosophy  and  theology 
and  the  teaching  of  these  sciences  to  their  students  must  be 
accurately  carried  out  by  Professors  [in  seminaries,  etc.] 
according  to  the  arguments,  doctrine,  and  principles  of 
S.  Thomas  which  they  are  inviolately  to  hold. 


THE  LEONINE  EDITION. 

In  the  year  1879  Pope  Leo  XIIL  addressed  a  letter,  dated 
October  15,  to  Cardinal  de  Luca,  Prefect  of  the  Congregation 
of  Studies,  to  found  the  Academy  of  St.  Thomas.  In  this 
letter  the  Pope  mentions  his  intention  of  bringing  out  a 
new  edition  of  all  the  Saint's  works.  He  speaks  of  it  as 
an  edition,  *  quse  cuncta  omnino  Sancti  Doctoris  scripta 
complectatur  optimis  quoad  fieri  potest  formis  litterarum 
expressa  accurataque  emendata ;  iis  etiam  adhibitis  codi- 
cum  manuscriptorum  subsidiis,  quae  setate  hac  nostra  in 
lucem  et  usum  prolata  sunt.  Conjunctim  vero  edendas 
curabimus  clarissiraorum  ejus  interpretum,  ut  Thomae  de 
Vio  Cardinali  Cajetani  et  Ferrariensis,  lucubrationes  per  quas, 
tanquam  per  uberes  riviculos,  tanti  viri  doctrina  decurrit.' 
The  Motu  Propria  for  the  new  edition  appeared  January  18, 
1880.  In  this  it  was  ordered  that  the  new  edition  should 
be  reserved   to  the  Propaganda   Press.     The  edition  was 


xxxiv  THE  "  SUMMA  THEOLOGICA  " 

confided  to  Cardinal  de  Luca,  Cardinal  Simeoni,  and  Cardinal 
Zigliara.  With  the  works  of  St.  Thomas  they  were  directed 
to  edit  Cajetan  on  the  *  Summa  Theologica,*  and  Ferrariensis 
on  the  '  Contra  Gentiles.' 

Cardinal  Zigliara,  in  the  Preface  to  the  first  Volume,  says 
that,  in  obedience  to  the  command  of  His  Holiness,  *  Magister 
Generalis  Ordinis  Praedicatorum  cui  demandata  est  a 
Leone  XIII.,  cura  hujus  editionis  operum  Sti.  Thomae, 
quosdam  religiosos  in  scientiis  simul  et  arte  paleographica 
eruditos  designavit,  qui  bibliothecas  perlustrant,  codices 
optimae  notae  inquirunt,  scripta  S.  Thomae  inedita  diligenter 
investigant,  atque  omnia  scripta  notata  aliis  religiosis 
Romae  degentibus  et  novam  hanc  editionem  curantibus 
transmittant.' 

The  groundwork  of  the  new  edition  is  that  of  St.  Pius  V. 
(1570).  Little  is  known  of  the  history  of  this  edition. 
Several  learned  Dominicans  were  employed  in  it,  and 
among  them  Remigius  Nanni,  Cardinal  Justiniani,  and 
Thomas  Marriques,  S.P.A.  Magister.  It  is  the  best  of  all 
the  editions  of  the  '  Opera  Omnia '  published  up  to  the  time 
of  Leo  XIII.  As  the  Pope  says  in  his  letter  to  Cardinal  de 
Luca  :  '  Coetera  enim,  cum  veteres  timi  recentiores,  partim 
quod  non  omnia  S.  Thomae  scripta  exhibent,  partim  quod 
optimorum,  ejus  interpretum  atque  explanatorum  careant 
commentariis,  partim  quod  minus  diligenter  adornatae  sint, 
non  omnia  tulisse  punctum  videntur.' 

This  Piana,  or  Roman,  Edition,  however,  seems  to  have 
been  made  with  the  help  of  earlier  editions  rather  than  of  the 
manuscripts. 

The  first  Volume  of  the  Leonine  Edition  comprises  the 
*  Dissertation  of  De  Rubeis  on  the  Life  and  Writings  of  St. 
Thomas,'  also  the  '  Commentaries  of  the  Saint  on  Aristotle's 
Works,'  *  Peri  Hermenias,'  and  '  Posteriora  Analytica.' 
As  St.  Thomas's  Commentaries  on  the  former  terminate  at 
the  end  of  the  Second  Book,  Cajetan's  Commentary  on  the 
remainder  has  been  given. 

The  Greek  text  of  Aristotle  (Didot's  edition)  has  been 
inserted  in  place  of  the  second  Latin  version  given  by  the 
Piana,  synopses  of  each  lesson  and  copious  notes  being  added. 


THE  LEONINE  EDITION  xxxv 

The  second  Volume  gives  the  Commentaries  on  the  eight 
books  of  Aristotle's '  Physics/  and  the  third  Volume  contains 
those  on  the  treatises,  '  De  Coelo  et  Mundo/  *  De  Generatione 
et  Corruptione,*  and  the  '  Meteorologia.* 

It  is  worthy  of  note  that  up  to  the  time  when  the  new 
edition  was  undertaken,  the  Commentary  on  both  of  the 
books,  '  De  Generatione  et  Corruptione,'  was  looked  upon  as 
genuine  work  of  St.  Thomas  ;  but  by  means  of  the  manu- 
scripts, as  well  as  from  internal  evidence  and  discovery  of 
their  origin  and  source,  it  has  been  proved  in  the  Preface  to 
the  third  Volume,  that  only  the  first  seventeen  lessons  of 
the  Commentary  on  the  First  Book  are  by  St.  Thomas,  the 
remainder  on  the  First  Book,  and  all  on  the  Second,  being 
drawn  from  Albertus  Magnus. 

Discoveries  were  also  made  concerning  the  Commentary 
on  the  books  of  the  *  Meteorologia,'  as  may  be  seen  in  the 
Preface.  That  on  the  Third  and  Fourth  were  known  to  be 
spurious.  That  on  the  Third  Book  is  taken  from  Peter  of 
Alvernia  ;  that  in  the  Leonine  Edition,  the  Commentary  on 
the  last  lesson  of  the  Second  Book,  is  also  shown  to  be 
taken  from  Albertus  Magnus. 

On  the  publication  of  the  third  Volume,  the  Pope 
addressed  a  Letter  to  Cardinals  Simeoni  and  Zigliara 
(Cardinal  de  Luca  had  died),  dated  October  ii,  1886,  ex- 
pressing his  wish  that  the  '  Summa  Theologica '  and  *  Summa 
Contra  Gentes '  should  be  the  next  edited  and  published. 

Of  the  former,  up  to  this  time  (1906)  nine  volumes  have 
been  published,  containing  almost  all  that  St.  Thomas  wrote 
before  his  death.  With  these  appears  the  Commentary  of 
Cajetan.  The  text  of  St.  Thomas  has  been  compared  with 
manuscripts  and  early  editions ;  quotations  have  been 
verified.  Each  manuscript  used  in  the  edition  has  been 
read  through,  and  when  it  differs  from  the  Plana,  a  note  is 
made  of  the  variant.  In  composing  the  second  Volume  no 
less  than  20,000  variants  were  marked. 

The  printing  of  the  work  was  done  at  the  Propaganda 
Press.  The  work  was  confided  wholly  to  the  Dominican 
Order  by  Pope  Leo  XIII.  before  his  death.

PROLOGUE 

Because  the  doctor  of  catholic  truth  ought  not  only  to 
teach  the  proficient,  but  also  to  instruct  beginners  (according 
to  the  Apostle:  As  unto  little  ones  in  Christ,  I  gave  you  milk 
to  drink,  not  meat — i  Cor.  iii.  i,  2),  we  purpose  in  this  book 
to  treat  of  whatever  belongs  to  the  Christian  religion,  in 
such  a  way  as  may  tend  to  the  instruction  of  beginners. 
We  have  considered  that  students  in  this  doctrine  have  not 
seldom  been  hampered  by  what  they  have  found  written 
by  other  authors,  partly  on  account  of  the  multiplication 
of  useless  questions,  articles,  and  arguments,  partly  also 
because  those  things  that  are  needful  for  them  to  know 
are  not  taught  according  to  the  order  of  the  subject-matter, 
but  according  as  the  plan  of  the  book  might  require,  or 
the  occasion  of  the  argument  offer,  partly,  too,  because 
frequent  repetition  brought  weariness  and  confusion  to  the 
minds  of  the  readers. 

Endeavouring  to  avoid  these  and  other  Hke  faults,  we 
shall  try,  by  God's  help,  to  set  forth  whatever  is  included 
in  this  sacred  doctrine  as  briefly  and  clearly  as  the  matter 
itself  may  allow.

THE  "SUMMA  THEOLOGIGA " 


FIRST    PART. 

QUESTION  I. 

THE  NATURE  AND  EXTENT  OF  SACRED  DOCTRINE. 

{In  Ten  Articles.) 

To  place  our  purpose  within  proper  limits,  we  first  endeavour 
to  investigate  the  nature  and  extent  of  this  sacred  doctrine. 
Concerning  this  there  are  ten  points  of  inquiry : — 

(i)  Whether  it  is  necessary  ?  (2)  Whether  it  is  a 
science  ?  (3)  Whether  it  is  one  or  many  ?  (4)  Whether 
it  is  speculative  or  practical  ?  (5)  How  it  is  compared  with 
other  sciences  ?  (6)  Whether  it  is  the  same  as  wisdom  ? 
(7)  Whether  God  is  its  subj  ect-matter  ?  (8)  Whether  it 
is  a  matter  of  argument  ?  (9)  Whether  it  rightly  employs 
metaphors  and  similes  ?  (10)  Whether  the  Sacred  Scripture 
of  this  doctrine  may  be  expounded  in, different  senses  ?j 

First  Article. 

whether,  besides  philosophy,  any  further  doctrine  is 

required  ? 

We  proceed  thus  to  the  First  Article  : — ■ 

Objection  i.  It  seems  that,  besides  philosophical  science, 
we  have  no  need  of  any  further  knowledge.  For  man  should 
not  seek  to  know  what  is  above  reason:  Seek  not  the  things 
that  are  too  high  for  thee  (Ecclus.  iii.  22).  But  whatever  is 
not  above  reason  is  fully  treated  ofjin  philosophical  science* 
I.  t 


Q.  I.  Art.  i     THE  "  SUMMA  THEOLOGICA  "  2 

Therefore  any  other  knowledge  besides  philosophical  science 
is  superfluous. 

Obj.  2.  Further,  knowledge  can  be  concerned  only  with 
being,  for  nothing  can  be  known,  save  what  is  true;  and  all 
that  is,  is  true.  But  everything  that  is,  is  treated  of  in 
philosophical  science — even  God  Himself;  so  that  there  is 
a  part  of  philosophy  called  theology,  or  the  divine  science, 
as  Aristotle  has  proved  (Metaph.  vi.).  Therefore,  besides 
philosophical  science,  there  is  no  need  of  any  further  know- 
ledge. ^^, 

On  the  contrary,  It  is  written  (2  Tim.  iii.  16) :  All  Scripture 
inspired  oj  God,  is  profitable  to  teach,  to  reprove,  to  correct,  to 
instruct  injustice.  Now  Scripture,  inspired  of  God,  is  no  part 
of  philosophical  science,  which  has  been  built  up  by  human 
reason.  Therefore  it  is  useful  that  besides  philosophical 
science  there  should  be  other  knowledge — i.e.,  inspired  of 
God. 

/  answer  that.  It  was  necessary  for  man's  salvation  that 
there  should  be  a  knowledge  revealed  by  God,  besides 
philosophical  science  built  up  by  human  reason.  Firstly, 
indeed,  'because  man  is  directed  to  God,  as  to  an  end  that 
surpasses  the  grasp  of  his  reason;  The  eye  hath  not  seen, 
0  God,  besides  Thee,  whfit  things  Thou  hast  prepared  for  them 
that  wait  for  Thee  (Isa.'lxiv.  4).  But  the  end  must  first  be 
known  by  men  who  are  to  direct  their  thoughts  and  actions 
to  the  end.  Hence  it  was  necessary  for  the  salvation  of 
man  that  certain  truths  which  exceed  human  reason  should 
be  made  known  to  him  by  divine  revelation.  Even  as 
regards  those  truths  about  God  which  human  reason  could 
have  discovered,  it  was  necessary  that  man  should  be  taught 
by  a  divine  revelation;  because  the  truth  about  God  such  as 
reason  could  discover,  would  only  be  known  by  a  few,  and 
that  after  a  long  time,  and  with  the  admixture  of  many  errors. 
Whereas  man's  whole  salvation,  which  is  in  God,  depends 
upon  the  knowledge  of  this  truth.  Therefore,  in  order  that 
the  salvation  of  men  might  be  brought  about  more  fitly 
and  more  surely,  it  was  necessary  that  they  should  be  taught 
divine  truths  by  divine  revelation.    It  was  therefore  neces-

sary  that,  Ibesides  philosophical  science  built  up  by  reason, 
there  shouH  be  a  sacred  science  learnt  through  revelation.( 

Reply  Obj.  i.  Although  those  things  which  are  beyond 
man's  knowledge  may  not  be  sought  for  by  man  through 
his  reason,  nevertheless,  once  they  are  revealed  by  God, 
they  must  be  accepted  by  faith.  Hence  the  sacred  text  ^ 
continues.  For  many  things  are  shown  to  thee  above  the  under- 
standing of  man  (Ecclus.  iii.  25).  And  in  this  the  sacred" 
science  consists.  ^^^^ 

Reply  Obj.  2.  Sciences  are  differentiated  according  to  the 
rarious  means  through  which  knowledge  is  obtained.  For 
the  astronomer  and  the  physicist  both  may  prove  the  same 
conclusion — that  the  earth,  for  instance,  is  round:  the 
astronomer  by  means  of  mathematics  {i.e.,  abstracting 
from  matter),  but  the  physicist  by  means  of  matter  itself. 
Hence  there  is  no  reason  why  those  things  which  may  be 
learnt  from  philosophical  science,  so  far  as  they  can  be 
known  by  natural  reason,  may  not  also  be  taught  us  by 
another  science  so  far  as  they  fall  within  revelation.  Hence 
theology  included  in  sacred  doctrine  differs  in  kind  from 
that  theology  which  is  part  of  philosophy. 

Second  Article, 
whether  sacred  doctrine  is  a  science  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  sacred  doctrine  is  not  a  science 
For  every  science  proceeds  from  self-evident  principles. 
But  sacred  doctrine  proceeds  from  articles  of  faith  which 
are  not  self-evident,  since  their  truth  is  not  admitted  by 
all:  For  all  men  have  not  faith  (2  Thess.  iii.  2).  Therefore 
sacred  doctrine  is  not  a  science. 

Obj.  2.  Further,  no  science  deals  with  individual  facts. 
But  this  sacred  science  treats  of  individual  facts,  such  as 
the  deeds  of  Abraham,  Isaac,  and  Jacob,  and  such  like. 
Therefore  sacred  doctrine  is  not  a  science. 

On  the  contrary,  Augustine  says  (De  Trin.  xiv.  i),  ^  this 
science  alone  belongs  that  whereby  saving  faith  is  begotten, 


Q.  I.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  4 

nourished,  protected,  and  strengthened.  But  this  can  be  said 
of  no  science  except  sacred  doctrine.  Therefore  sacred 
doctrine  is  a  science. 

/  answer  that,  Sacred  doctrine  is  a  science.  We  must 
bear  in  mind  that  there  are  two  kinds  of  sciences.  There  are 
some  which  proceed  from  a  principle  known  by  the  natural 
light  of  the  intelligence,  such  as  arithmetic  and  geometry  and 
the  like.  There  are  some  which  proceed  from  principles  known 
by  the  light  of  a  higher  science :  thus  the  science  of  perspec- 
tive proceeds  from  principles  established  by  geometry,  and 
^usic  from  principles  established  by  arithmetic.  So  it  is 
that  sacred  doctrine  is  a  science,  because  it  proceeds  from 
I  principles  established  by  the  light  of  a  higher  science, 
|namely,  the  science  of  God  and  the  blessed.  Hence,  just 
as  the  musician  accepts  on  authority  the  principles  taught 
him  by  the  mathematician,  so  sacred  science  is  established 
on  principles  revealed  by  God. 

Reply  Obj.  i.  The  principles  of  any  science  are  either  in 
themselves  self-evident,  or  reducible  to  the  conclusions  of  a 
higher  science;  and  such,  as  we  have  said,  are  the  principles 
of  sacred  doctrine. 

Reply  Obj.  2.  Individual  facts  are  treated  of  in  sacred 
doctrine,  not  because  it  is  concerned  with  them  principally : 
but  they  are  introduced  rather  both  as  examples  to  be 
followed  in  our  lives  (as  in  moral  sciences),  and  in  order  to 
establish  the  authority  of  those  men  through  whom  the 
divine  revelation,  on  which  this  sacred  scripture  or  doctrine 
is  based,  has  come  down  to  us. 

Third  Article, 
whether  sacred  doctrine  is  one  science  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  sacred  doctrine  is  not  one 
science;  for  according  to  the  Philosopher  (Poster,  i.)  that 
science  is  one  which  treats  only  of  one  class  of  subjects.  But  the 
creator  and  the  creature,  both  of  whom  arfe  tredtfed  of  in 
sacred   doctrine,   cannot  be  grouped   together   under  one 


5  NATURE  OF  SACRED  DOCTRINE     Q.  i.  Art.  3 

class  of  subjects.     Therefore  sacred  doctrine   is  not  one 
science. 

Ohj.  2.  Further,  in  sacred  doctrine  we  treat  of  angels, 
corporeal  creatures,  and  human  morality.  But  these  belong 
to  separate  philosophical  sciences.  Therefore  sacred  doc- 
trine cannot  be  one  science. 

On  the  contrary,  Holy  Scripture  speaks  of  it  as  one  science : 
Wisdom  gave  him  the  knowledge  [scientiam]  of  holy  things 
(Wisd.  X.  10). 

I  answer  that,  sacred  doctrine  is  one  science.  The  unity  of 
a  faculty  or  habit  is  to  be  gauged  by  its  object,  not  indeed, 
in  its  material  aspect,  but  as  regards  the  precise  formality 
under  which  it  is  an  object.  For  example,  man,  ass,  stone, 
agree  in  the  one  precise  formality  of  being  coloured;  and 
colour  is  the  formal  object  of  sight.  Therefore,  because 
Sacred  Scripture  considers  things  precisely  under  the 
formality  of  being  divinely  revealed,  whatever  has  been 
divinely  revealed  possesses  the  one  precise  formality  of  the 
object  of  this  science;  and  therefore  is  included  under  sacred 
doctrine  as  under  one  science.  -===" 

Reply  Ohj.  i.  Sacred  doctrine  does  not  treat  of  God  and 
creatures  equally,  but  of  God  primarily;  and  of  creatures 
only  so  far  as  they  are  referable  to  God  as  their  beginning  or 
end.     Hence  the  unity  of  this  science  is  not  impaired. 

Reply  Ohj.  2.  Nothing  prevents  inferior  faculties  or  habits 
from  being  differentiated  by  something  which  falls  under  a 
higher  faculty  or  habit  as  well;  because  the  higher  faculty 
or  habit  regards  the  object  in  its  more  universal  formality, 
as  the  object  of  the  common  sense  is  whatever  affects  the 
senses,  including,  therefore,  whatever  is  visible  or  audible. 
Hence  the  common  sense,  although  one  faculty,  extends 
to  all  the  objects  of  the  five  senses.  Similarly,  objects 
which  are  the  subject-matter  of  different  philosophical 
sciences  can  yet  be  treated  of  by  this  one  single  sacred 
science  under  one  aspect  precisely  so  far  as  they  can  be 
included  in  revelation.  So  that  in  this  way  sacred  doctrine 
bears,  as  it  were,  the  stamp  of  the  divine  science,  which 
is  one  and  simple,  yet  extends  to  everything.

Fourth  Article, 
whether  sacred  doctrine  is  a  practical  science  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  sacred  doctrine  is  a  practical 
science;  for  a  practical  science  is  that  which  ends  in  action 
according  to  the  Philosopher  (Metaph.  ii.).  But  sacred 
doctrine  is  ordained  to  action;  \Be  ye  doers  of  the  word,  and 
not  hearers  only  (Jas.  i.  22).  Therefore  sacred  doctrine  is  a 
practical  science.-  -     ^ 

Obj.  2.  Further,  sacred  doctrine  is  divided  into  the  Old 
and  the  New  Law.  But  law  implies  a  moral  science,  which 
is  a  practical  science.  Therefore  sacred  doctrine  is  a  prac- 
tical science. 

On  the  contrary,  Every  practical  science  is  concerned  with 
human  operations;  as  moral  science  is  concerned  with 
human  acts,  and  architecture  with  buildings.  But  sacred 
doctrine  is  chiefly  concerned  with  God,  whose  handiwork 
is  especially  man.  Therefore  it  is  not  a  practical  but  a 
speculative  science. 

/  answer  that,  Sacred  doctrine,  being  one,  extends  to 
things  which  belong  to  different  philosophical  sciences, 
because  it 'considers  in  each  the  same  formal  aspect,  namely 
so  far  as  they  can  be  known  through  divine  revelation. 
Hence,  although  among  the  philosophical  sciences  one  is 
speculative  and  another  practical,  nevertheless  sacred 
doctrine  includes  both;  as  God,  by  one  and  the  same 
science,  knows  both  Himself  and  His  works.  Still,  it  is 
speculative  rather  than  practical,  because  it  is  more  con- 
cerned with  divine  things  than  with  human  acts;  though  it 
does  treat  even  of  these  latter,  inasmuch  as  man  is  ordained 
by  them  to  the  perfect  knowledge  of  God,  in  which  consists 
eternal  bliss.     This  is  a  sufficient  answer  to  the  Objections.

Fifth  Article. 

whether  sacred  doctrine  is  nobler  than  other 

sciences  ? 

We  proceed  thus  to  the  Fifth  Article  : — 

Objection  i.  It  seems  that  sacred  doctrine  is  not  nobler 
than  other  sciences;  for  the  nobility  of  a  science  depends 
on  the  certitude  it  establishes.  But  other  sciences,  the 
principles  of  which  cannot  be  doubted,  seem  to  be  more 
certain  than  sacred  doctrine;  for  its  principles — namely, 
articles  of  faith — can  be  doubted.  Therefore  other  sciences 
seem  to  be  nobler. 

Ohj.  2.  Further,  it  is  the  sign  of  a  lower  science  to  depend 
upon  a  higher;  as  music  depends  upon  arithmetic.  But 
sacred  doctrine  does  in  a  sense  depend  upon  the  philo- 
sophical sciences;  for  Jerome  observes,  in  his  Epistle  to 
Magnus,  that  the  ancient  doctors  so  enriched  their  books  with 
the  ideas  and  phrases  of  the  philosophers,  that  thou  knowest 
not  what  more  to  admire  in  them,  their  profane  erudition  or 
their  scriptural  learning.  Therefore  sacred  doctrine  is 
inferior  to  other  sciences. 

On  the  contrary.  Other  sciences  are  called  the  handmaidens  of 
this  one :  Wisdom  sent  her  maids  to  invite  to  the  tower  (Prov.  ix.3). 

I  answer  that,  Since  this  science  is  partly  speculative  and 
partly  practical,  it  transcends  all  others  speculative  and_J 
practical.  Now  one  speculative  science  is  said  to  be  nobler 
than  another,  either  by  reason  of  its  greater  certitude,  or 
by  reason  of  the  higher  worth  of  its  subject-matter.  In 
both  these  respects  this  science  surpasses  other  speculative 
sciences;  in  point  of  greater  certitude,  because  other  sciences 
derive  their  certitude  from  the  natural  light  of  human 
reason,  which  can  err;  whereas  this  derives  its  certitude 
from  the  light  of  the  divine  knowledge,  which  cannot  be 
misled:  in  point  of  the  higher  worth  of  its  subject-matter, 
because  this  science  treats  chiefly  of  those  things  which  by 
their  sublimity  transcend  human  reason;  while  other  sciences 
consider  only  those  things  which  are  within  reason's  grasp. 
Of  the  practical  sciences,  that  one  is  nobler  which  is  ordained 


Q.  I.  Art.  6    THE  "  SUMMA  THEOLOGICA  "  S 

to  a  further  purpose,  as  political  science  is  nobler  than  mili- 
tary science;  for  the  good  of  the  army  is  directed  to  the  good 
of  the  State.    But  the  purpose  of  this  science,  in  so  far  as  it  is 
practical,  is  eternal  bliss ;  to  which  as  to  an  ultimate  end  the 
purposes  of  every  practical  science  are  directed.     Hence  it  is 
clear  that  from  every  standpoint  it  is  nobler  than  other  sciences. 
Reply  Ohj.  i.  It  may  well  happen  that  what  is  in  itself 
the  more  certain  may  seem  to  us  the  less  certain  on  account 
of  the  weakness  of  our  intelligence,  "which  is  dazzled  by  the 
clearest  objects  of  nature;  as  the  owl  is  dazzled  by  the  light 
of  the  sun  "  (Metaph.  ii.,  led.  i.).    Hence  the  fact  that  some 
happen  to  doubt  about  articles  of  faith  is  not  due  to  the 
uncertain  nature  of  the  truths,  but  to  the  weakness  of  human 
intelligence;    yet   the  slenderest   knowledge  that  may  be 
obtained  of  the  highest  things  is  more  desirable  than  the 
most  certain  knowledge  obtained  of  lesser  things,  as  is  said 
in  de  Animalibus  xi. 

Reply  Ohj.  2.  This  science  can  in  a  sense  depend  upon  the 
philosophical  sciences,  not  as  though  it  stood  in  need  of  them, 
but  only  in  order  to  make  its  teaching  clearer.  For  it  accepts 
its  principles  not  from  other  sciences;  but  immediately 
from  God,  by  revelation.  Therefore  it  does  not  depend 
upon  other  sciences  as  upon  the  higher,  but  makes  use  of 
them  as  of  the  lesser,  and  as  handmaidens:  even  so  the 
master  sciences  make  use  of  the  sciences  that  supply  their 
materials,  as  political  of  military  science.  That  it  thus  uses 
them  is  not  due  to  its  own  defect  or  insufficiency,  but  to  the 
defect  of  our  intelligence,  which  is  more  easily  led  by  what 
is  known  through  natural  reason  (from  which  proceed  the 
other  sciences),  to  that  which  is  above  reason,  such  as  aire 
the  teachings  of  this  science. 

Sixth  Article, 
whether  this  doctrine  is  the  same  as  wisdom  ? 

}Ve  proceed  thus  to  the  Sixth  Article  : — 
Objection  i.  It  seems  that  this  doctrine  is  not  the  same 
as  wisdom.     For  no  doctrine  which  borrows  its  principles 


9  NATURE  OF  SACRED  DOCTRINE    Q.  i.Art.6 

is  worthy  of  the  name  of  wisdom;  seeing  that  the  wise  man 
directs,  and  is  not  directed  [Metaph.  i.).     But  this  doctrine, 
borrows  its  principles.     Therefore  this  science  is  not  wisdom. 

Ohj.  2.  Further,  it  is  a  part  of  wisdom  to  prove  the  principles 
of  other  sciences.  Hence  it  is  called  the  chief  of  sciences,  as  is 
clear  in  Ethic  vi.  But  this  doctrine  does  not  prove  the  princi- 
ples of  other  sciences.    Therefore  it  is  not  the  same  as  wisdom. 

Ohj.  3.  Further,  this  doctrine  is  acquired  by  study, 
whereas  wisdom  is  acquired  by  God's  inspiration;  so  that 
it  is  numbered  among  the  gifts  of  the  Holy  Spirit  (Isa.  xi.  2). 
Therefore  this  doctrine  is  not  the  same  as  wisdom. 

On  the  contrary,  It  is  written  (Deut.  iv.  6) :  This  is  your 
wisdom  and  understanding  in  the  sight  of  nations.  .— ^ 

/  answer  that,  This  doctrine  is  wisdom  above  all  human 
wisdom;  not  merely  in  any  one  order,  but  absolutely.  For 
since  it  is  the  part  of  a  wise  man  to  arrange  and  to  judge, 
and  since  lesser  matters  should  be  judged  in  the  light  of 
some  higher  principle,  he  is  said  to  be  wise  in  any  one  order , 
who  considers  the  highest  principle  in  that  order:  thus 
in  the  order  of  building  he  who  plans  the  form  of  the  house 
is  called  wise  and  architect,  in  opposition  to  the  inferior 
labourers  who  trim  the  wood  and  make  ready  the  stones: 
As  a  wise  architect  I  have  laid  the  foundation  (i  Cor.  iii.  10). 
Again,  in  the  order  of  all  human  Hfe,  the  prudent  man  is 
called  wise,  inasmuch  as  he  directs  his  acts  to  a  fitting 
end:  Wisdom  is  prudence  to  a  man  (Pro v.  x.  23).  There- 
fore he  who  considers  absolutely  the  highest  cause  of  the 
whole  universe,  namely  God,  is  most  of  all  called  wise. 
Hence  wisdom  is  said  to  be  the  knowledge  of  divine  things, 
as  Augustine  says  [De  Trin.  xii.  14).  But  sacred  doctrine 
essentially  treats  of  God  viewed  as  the  highest  cause — ■ 
not  only  so  far  as  He  can  be  known  through  creatures  just 
as  philosophers  knew  Him — That  which  is  known  of  God  is 
manifest  in  them  (Rom.  i.  19) — but  also  so  far  as  He  is  known 
to  Himself  alone  and  revealed  to  others.  Hence  sacred 
doctrine  is  especially  called  wisdom. 

Reply  Ohj,  i.  Sacred  doctrine  derives  its  principles 
not    from  any  human  knowledge,    but   from  the   divine 


Q.  I.  Art  7      THE  "  SUMMA  THEOLOGICA  "  10 

knowledge,  through  which,  as  through  the  highest  wisdom, 
all  our  knowledge  is  set  in  order. 

Reply  Ohj.  2.  The  principles  of  other  sciences  either  are 
evident  and  cannot  be  proved,  or  are  proved  by  natural 
reason  through  some  other  science.  But  the  knowledge 
proper  to  this  science  comes  through  revelation,  and  not 
through  natural  reason.  Therefore  it  has  no  concern  to 
prove  the  principles  of  other  sciences,  but  only  to  judge  of 
them.  Whatsoever  is  found  in  other  sciences  contrary  to 
any  truth  of  this  science,  must  be  condemned  as  false: 
Destroying  counsels  and  every  height  that  exalteth  itself  against 
the  knowledge  of  God  (2  Cor.  x.  4,  5). 

Reply  Ohj.  3.  Since  judgment  appertains  to  wisdom,  the 
twofold  manner  of  judging  produces  a  twofold  wisdom.  A 
man  may  judge  in  one  way  by  inclination,  as  whoever  has 
the  habit  of  a  virtue  judges  rightly  of  what  concerns  that 
virtue  by  his  very  inclination  towards  it.  Hence  it  is  the 
virtuous  man,  as  we  read,  who  is  the  measure  and  rule 
of  human  acts.  In  another  way,  by  knowledge,  just  as 
a  man  learned  in  moral  science  might  be  able  to  judge 
rightly  about  virtuous  acts,  though  he  had  not  the  virtue. 
The  first  manner  of  judging  divine  things  belongs  to  that 
wisdom  which  is  set  down  among  the  gifts  of  the  Holy 
Ghost:  The  spiritual  man  judgeth  all  things  (i  Cor.  ii.  15). 
And  Dionysius  says  (Div.  Norn,  ii.):  Hierotheus  is  taught 
not  by  mere  learning,  hut  hy  experience  of  divine  things.  The 
second  manner  of  judging  belongs  to  this  doctrine,  which  is 
acquired  by  study,  though  its  principles  are  obtained  by 
revelation. 


Seventh  Article, 
whether  god  is  the  object  of  this  science  ? 

We  proceed  thus  to  the  Seventh  Article  : — 

Ohjection  i.  It  seems  that  God  is  not  the  object  of  this 
science.  For  in  every  science  the  nature  of  its  object  is 
presupposed.  But  this  science  cannot  presuppose  the 
essence  of  God,  for  Damascene  says  [De  Fid.  Orth.  I  iv.): 


11  NATURE  OF  SACRED  DOCTRINE    Q.i.Art.7 

It  is  impossible  to  define  the  essence  of  God.     Therefore  God 
is  not  the  object  of  this  science. 

Ohj.  2.  Further,  whatever  conclusions  are  reached  in  any 
science  must  be  comprehended  under  the  object  of  the 
science.  But  in  Holy  Writ  we  reach  conclusions  not  only 
concerning  God,  but  concerning  many  other  things,  such  as 
creatures  and  human  morality.  Therefore  God  is  not  the 
object  of  this  science. 

On  the  contrary.  The  object  of  the  science  is  that  of  which 
it  principally  treats.  But  in  this  science  the  treatment  is 
mainly  about  God;  for  it  is  called  theology,  as  treating  of 
God.     Therefore  God  is  the  object  of  this  science. 

/  answer  that,  God  is  the  object  of  this  science.     The 
relation  between  a  science  and  its  object  is  the  same  as  that 
between  a  habit  or  faculty  and  its  object.     Now  properly 
speaking  the  object  of  a  faculty  or  habit  is  the  thing  under 
the  aspect  of  which  all  things  are  referred  to  that  faculty  or 
habit,  as  man  and  stone  are  referred  to  the  faculty  of  sight 
in  that  they  are  coloured.     Hence  coloured  things  are  the 
proper  objects  of  sight.     But  in  sacred  science  all  things  are 
treated  of  under  the  aspect  of  God;  either  because  they 
are  God  Himself;  or  because  they  refer  to  God  as  their  begin- 
ning and  end.     Hence  it  follows  that  God  is  in  very  truth 
the  object    of    this   science.     This  is  clear   also  from  the 
principles  of  this  science,  namely,  the  articles  of  faith,  for 
faith  is  about  God.     The  object  of  the  principles  and  of 
the  whole  science  must  be  the  same,  since  the  whole  science 
is  contained  virtually  in  its  principles.     Some,  however, 
looking  to  what  is  treated  of  in  this  science,  and  not  to  the 
aspect  under  which  it  is  treated,  have  asserted  the  object 
of  this  science  to  be  something  other  than  God — that  is, 
either  things  and  signs;  or  the  works  of  salvation;  or  the 
whole  Christ,  as  the  head  and  members.     Of  all  these  things, 
in  truth,  we  treat  in  this  science,  but  so  far  as  they  have 
reference  to  God. 

Reply  Ohj.  i.  Although  we  cannot  know  in  what  consists 
the  essence  of  God,  nevertheless  in  this  science  we  make 
use  of  His  effects,  either  of  nature  or  of  grace,  in  place  of  a 


Q.  I.  Art.  8    THE  "  SUMMA  THEOLOGICA  "  12 

definition,  in  regard  to  whatever  is  treated  of  in  this  science 
concerning  God;  even  as  in  some  philosophical  sciences  we 
demonstrate  something  about  a  cause  from  its  effect,  by 
taking  the  effect  in  place  of  a  definition  of  the  cause. 

Reply  Ohj.  2.  Whatever  other  conclusions  are  reached  in 
this  sacred  science  are  comprehended  under  God,  not  as 
parts  or  species  or  accidents,  but  as  in  some  way  related 
to  Him.

We  proceed  thus  to  the  Eighth  Article  : — 

Objection  i.  It  seems  this  doctrine  is  not  a  matter  of 
argument.  For  Ambrose  says  [De  Fide,  i) :  Put  arguments 
aside  where  faith  is  sought.  But  in  this  doctrine  faith  espe- 
cially is  sought:  But  these  things  are  written  that  you  may 
believe  (John  xx.  31).  Therefore  sacred  doctrine  is  not  a 
matter  of  argument. 

Obj.  2.  Further,  if  it  is  a  matter  of  argument,  the  argu- 
ment is  either  from  authority  or  from  reason.  If  it  is  from 
authority,  it  seems  unbefitting  its  dignity,  for  the  proof 
from  authority  is  the  weakest  form  of  proof.  But  if  from 
reason,  this  is  unbefitting  its  end,  because,  according  to 
Gregory  (Homil.  26),  faith  has  no  merit  in  those  things  of 
which  human  reason  brings  its  own  experience.  Therefore 
sacred  doctrine  is  not  a  matter  of  argument. 

On  the  contrary,  The  Scripture  says  that  a  bishop  should 
embrace  that  faithful  word  which  is  according  to  doctrine, 
that  he  may  be  able  to  exhort  in  sound  doctrine  and  to  convince 
the  gainsay ers  (Tit.  i.  9). 

/  answer  that.  As  other  sciences  do  not  argue  in  proof 
of  their  principles,  but  argue  from  their  principles  to  demon- 
strate other  truths  in  these  sciences:  so  this  doctrine  does 
not  argue  in  proof  of  its  principles,  which  are  the  articles  of 
faith,  but  from  them  it  goes  on  to  prove  something  else; 
as  the  Apostle  from  the  resurrection  of  Christ  argues  in 
proof  of  the  general  resurrection  (i  Cor.  xv.).     However,  it 


13  NATURE  OF  SACRED  DOCTRINE  Q.  i.  Art.  8 

is  to  be  borne  in  mind,  in  regard  to  the  philosophical  sciences, 
that  the  inferior  sciences  neither  prove  their  principles  nor 
dispute  with  those  who  deny  them,  but  leave  this  to  a  higher 
science;  whereas  the  highest  of  them,  viz.,  metaphysics,  can 
dispute  with  one  who  denies  its  principles,  if  only  the  oppo- 
nent will  make  some  concession;  but  if  he  concede  nothing, 
it  can  have  no  dispute  with  him,  though  it  can  answer  his 
objections.  Hence  Sacred  Scripture,  since  it  has  no  science 
above  itself,  can  dispute  with  one  who  denies  its  principles 
only  if  the  opponent  admits  some  at  least  of  the  truths 
obtained  through  divine  revelation;  thus  we  can  argue  with 
heretics  from  texts  in  Holy  Writ,  and  against  those  who 
deny  one  article  of  faith  we  can  argue  from  another.  If 
our  opponent  believes  nothing  of  divine  revelation,  there 
is  no  longer  any  means  of  proving  the  articles  of  faith  by 
reasoning,  but  only  of  answering  his  objections — if  he  has 
any — against  faith.  Since  faith  rests  upon  infallible  truth,, 
and  since  the  contrary  of  a  truth  can  never  be  demonstrated,] 
it  is  clear  that  the  arguments  brought  against  faith  cannotfp 
be  demonstrations,  but  are  difficulties  that  can  be  answered/ 

Reply  Ohj.  i.  Although  arguments  from  human  reason 
cannot  avail  to  prove  what  must  be  received  on  faith, 
nevertheless  this  doctrine  argues  from  articles  of  faith  to 
other  truths. 

Reply  Ohj.  2.  This  doctrine  is  especially  based  upon 
arguments  from  authority,  inasmuch  as  its  principles  are 
obtained  by  revelation:  thus  we  ought  to  believe  on  the 
authority  of  those  to  whom  the  revelation  has  been  made. 
Nor  does  this  take  away  from  the  dignity  of  this  doctrine, 
for  although  the  argument  from  authority  based  on  human 
reason  is  the  weakest,  yet  the  argument  from  authority 
based  on  divine  revelation  is  the  strongest.  But  sacred 
doctrine  makes  use  even  of  human  reason,  not,  indeed, 
to  prove  faith  (for  thereby  the  merit  of  faith  would  come 
to  an  end),  but  to  make  clear  other  things  that  are  put 
forward  in  this  doctrine.  Since  therefore  grace  does  not 
destroy  nature,  but  perfects  it,  natural  reason  should  minister 
to  faith  as  the  natural  bent  of  the  will  ministers  to  charity; 


g.  I.  Art.  9    THE  "  SUMMA  THEOLOGICA  "  14 

Hence  the  Apostle  says:  Bringing  into  captivity  every  under- 
standing unto  the  obedience  of  Christ  (2  Cor.  x.  5).  Hence 
sacred  doctrine  makes  use  also  of  the  authority  of  philoso- 
phers in  those  questions  in  which  they  were  able  to  know  the 
truth  by  natural  reason,  as  Paul  quotes  a  saying  of  Aratus : 
As  some  also  of  your  own  poets  said;  For  we  are  also  His 
offspring  (Acts  xvii.  28).  Nevertheless,  sacred  doctrine 
makes  use  of  these  authorities  as  extrinsic  and  probable 
arguments ;  but  properly  uses  the  authority  of  the  canonical 
Scriptures  as  an  incontrovertible  proof,  and  the  authority 
of  the  doctors  of  the  Church  as  one  that  may  properly  be 
used,  yet  merely  as  probable.  For  our  faith  rests  upon  the 
revelation  made  to  the  apostles  and  prophets,  who  wrote 
the  canonical  books,  and  not  on  the  revelations  (if  any  such 
there  are)  made  to  other  doctors.  Hence  Augustine  says 
(Epist.  ad  Hieron.  xix.  i.) :  Only  those  books  of  Scripture 
which  are  called  canonical  have  I  learnt  to  hold  in  such  honour 
as  to  believe  their  authors  have  not  erred  in  any  way  in  writing 
them.  But  other  authors  I  so  read  as  not  to  deem  anything 
in  their  works  to  be  true,  merely  on  account  of  their  having  so 
thought  and  written,  whatever  may  have  been  their  holiness 
and  learning. 

Ninth  Article, 
whether  holy  scripture  should  use  metaphors  ? 

We  proceed  thus  to  the  Ninth  Article : — 

Objection  i.  It  seems  that  Holy  Scripture  should  not  use 
metaphors.  For  that  which  is  proper  to  the  lowest  science 
seems  not  to  befit  this  science,  which  holds  the  highest  place 
of  all.  But  to  proceed  by  the  aid  of  various  similitudes  and 
figures  is  proper  to  poetry,  the  least  of  all  the  sciences. 
Therefore  it  is  not  fitting  that  this  science  should  make  use 
of  such  similitudes. 

Obj.  2.  Further,  this  doctrine  seems  to  be  intended  to 
make  truth  clear.  Hence  a  reward  is  held  out  to  those  who 
manifest  it:  They  that  explain  me  shall  have  life  everlasting 
(Ecclus.  xxiv.  31).     But  by  such  similitudes  truth  is  ob- 


15  NATURE  OF  SACRED  DOCTRINE     Q.  i.  Art.  o 

scured.     Therefore  to  put  forward  divine  truths  by  liken- 
ing them  to  corporeal  things  does  not  befit  this  science. 

Obj.  3.  Further,  the  higher  creatures  are,  the  nearer  they 
approach  to  the  divine  likeness.  If  therefore  any  creature 
be  taken  to  represent  God,  this  representation  ought  chiefly 
to  be  taken  from  the  higher  creatures,  and  not  from  the 
lower;  yet  this  is  often  found  in  the  Scriptures. 

On  the  contrary,  It  is  written  (Osee  xii.  10) :  /  have  ^nuUiplied 
visions,  and  I  have  used  similitudes  by  the  ministry  of  the 
prophets.  But  to  put  forward  anything  by  means  of  simili- 
tudes is  to  use  metaphors.  Therefore  this  sacred  science 
may  use  metaphors. 

/  answer  that.  It  is  befitting  Holy  Writ  to  put  forward 
divine  and  spiritual  truths  by  means  of  comparisons  with 
material  things.  For  God  provides  for  everything  accord- 
ing to  the  capacity  of  its  nature.  Now  it  is  natural  to  man 
to  attain  to  intellectual  truths  through  sensible  objects, 
because  all  our  knowledge  originates  from  sense.  Hence  in 
Holy  Writ  spiritual  truths  are  fittingly  taught  under  the 
likeness  of  material  things.  This  is  what  Dionysius  says 
(CcBlest.  Hierarch.  i.):  We  cannot  be  enlightened  by  the  divine 
rays  except  they  be  hidden  within  the  covering  of  many  sacred 
veils.  It  is  also  befitting  Holy  Writ,  which  is  proposed  to 
all  without  distinction  of  persons — To  the  wise  and  to  the 
unwise  I  am  a  debtor  (Rom.  i.  I4)~that  spiritual  truths 
be  expounded  by  means  of  figures  taken  from  corporeal 
things,  in  order  that  thereby  even  the  simple  who  are  unable 
by  themselves  to  grasp  intellectual  things  may  be  able  to 
understand  it. 

Reply  Obj.  i.  Poetry  makes  use  of  metaphors  to  produce 
a  representation,  for  it  is  natural  to  man  to  be  pleased  with 
representations.  But  sacred  doctrine  makes  use  of  metaphors 
as  both  necessary  and  useful. 

Reply  Obj.  2.  The  ray  of  divine  revelation  is  not  ex- 
tinguished by  the  sensible  imagery  wherewith  it  is  veiled,  as 
Dionysius  says  (Ccelest.  Hierarch.  i.) ;  and  its  truth  so  far 
remains  that  it  does  not  allow  the  minds  of  those  to  whom 
the  revelation   has  been  made,  to  rest  in  the  metaphors. 


IX 


Q.  I  Art.  io    THE  "  SUMMA  THEOLOGICA  "  i6 

but  raises  them  to  the  knowledge  of  truths;  and  through 
those  to  whom  the  revelation  has  been  made  others  also 
may  receive  instruction  in  these  matters.  Hence  those 
things  that  are  taught  metaphorically  in  one  part  of  Scrip- 
ture, in  other  parts  are  taught  more  openly.  The  very 
hiding  of  truth  in  figures  is  useful  for  the  exercise  of  thought- 
ful minds,  and  as  a  defence  against  the  ridicule  of  the 
impious,  according  to  the  words  Give  not  that  which  is  holy  to 
dogs  (Matth.  vii.  6). 

Reply  Obj.  3.  As  Dionysius  says,  (loc.  cit.)  it  is  more 
fitting  that  divine  truths  should  be  expounded  under  the 
figure  of  less  noble  than  of  nobler  bodies,  and  this  for  three 
reasons.  Firstly,  because  thereby  men's  minds  are  the  better 
preserved  from  error.  For  then  it  is  clear  that  these  things 
are  not  literal  descriptions  of  divine  truths,  which  might 
have  been  open  to  doubt  had  they  been  expressed  under  the 
figure  of  nobler  bodies,  especially  for  those  who  could 
think  of  nothing  nobler  than  bodies.  Secondly,  because 
this  is  more  befitting  the  knowledge  of  God  that  we 
have  in  this  life.  For  what  He  is  not  is  clearer  to  us 
than  what  He  is.  Therefore  similitudes  drawn  from  things 
farthest  away  from  God  form  within  us  a  truer  estimate 
that  God  is  above  whatsoever  we  may  say  or  think  of  Him. 
Thirdly,  because  thereby  divine  truths  are  the  better 
hidden  from  the  unworthy. 

Tenth  Article, 
whether  in  holy  scripture  a  word  may  have  several 

SENSES  ? 

We  proceed  thus  to  the  Tenth  Article : — 

Objection  i.  It  seems  that  in  Holy  Writ  a  word  cannot 
have  several  senses,  historical  or  literal,  allegorical,  tropo- 
logical  or  moral,  and  anagogical.  For  many  different 
senses  in  one  text  produce  confusion  and  deception  and 
destroy  all  force  of  argument.  Hence  no  argument,  but 
only  fallacies,  can  be  deduced  from  a  multipUcity  of  pro- 
positions.    But  Holy  Writ  ought  to  be  able  to  state  the 


17  ^rATURE  OF  SACREf)  DOCTRINE    Q.  i.  Art.  id- 

truth  without  any  fallacy.    Therefore  in  it  there  cannot 
be  several  senses  to  a  word. 

Obj.  2.  Further,  Augustine  says  (De  util.  cred.  iii.)  that  the 
Old  Testament  has  a  fourfold  division  as  to  history,  etiology, 
analogy,  and  allegory.  Now  these  four  seem  altogether 
different  from  the  four  divisions  mentioned  in  the  first 
objection.  Therefore  it  does  not  seem  fitting  to  explain  the 
same  word  of  Holy  Writ  according  to  the  four  different 
senses  mentioned  above. 

Obj.  3.  Further,  besides  these  senses,  there  is  the  para- 
bolical, which  is  not  one  of  these  four. 

On  the  contrary,  Gregory  says  {Moral,  xx.,  i) :  Holy  Writ 
by  the  manner  of  its  speech  transcends  every  science,  because 
in  one  and  the  same  sentence,  while  it  describes  a  fact,  it  reveals 
a  fnystery. 

I  answer  that,  The  author  of  Holy  Writ  is  God,  in  whose 
power  it  is  to  signify  His  meaning,  not  by  words  only  (as 
man  also  can  do),  but  also  by  things  themselves.  So, 
whereas  in  every  other  science  things  are  signified  by  words, 
this  science  has  the  property,  that  the  things  signified  by 
the  words  have  themselves  also  a  signification.  Therefore 
that  first  signification  whereby  words  signify  things  belongs 
to  the  first  sense,  the  historical  or  literal.  That  significa- 
tion whereby  things  signified  by  words  have  themselves 
also  a  signification  is  called  the  spiritual  sense,  which  is 
based  on  the  literal,  and  presupposes  it.  Now  this 
spiritual  sense  has  a  threefold  division.  For  as  the  Apostle 
says  (Heb.  x.  i)  the  Old  Law  is  a  figure  of  the  New  Law, 
and  Dionysius  says  {Ccel.  Hier  i.)  the  New  Law  itself  is  a 
figure  of  future  glory.  Again,  in  the  New  Law,  whatever 
our  Head  has  done  is  a  type  of  what  we  ought  to  do.  There- 
fore, so  far  as  the  things  of  the  Old  Law  signify  the  things 
of  the  New  Law,  there  is  the  allegorical  sense ;  so  far  as  the 
things  done  in  Christ,  or  so  far  as  the  things  which  signify 
Christ,  are  types  of  what  we  ought  to  do,  there  is  the  moral 
sense.  But  so  far  as  they  signify  what  relates  to  eternal  glory, 
there  is  the  analogical  sense.  Since  the  literal  sense  is  that 
which  the  author  intends,  and  since  the  author  of  Holy 
I.  2 


Q.  I.  AtiT.  ID     THE  "  SUMMA  THEOLOGICA  "  i8 

Writ  is  God,  Who  by  one  act  comprehends  all  things  by 
His  intellect,  it  is  not  unfitting,  as  Augustine  says  (Confess. 
xii.),  if,  even  according  to  the  literal  sense,  one  word  in 
Holy  Writ  should  have  several  senses. 

Reply  Obj.  i.  The  multiplicity  of  these  senses  does  not 
produce  equivocation  or  any  other  kind  of  multiplicity, 
seeing  that  these  senses  are  not  multiplied  because  one  word 
signifies  several  things;  but  because  the  things  signified 
by  the  words  can  be  themselves  types  of  other  things. 
Thus  in  Holy  Writ  no  confusion  results,  for  all  the  senses 
are  founded  on  one— the  literal — from  which  alone  can 
any  argument  be  drawn,  and  not  from  those  intended  in 
allegory,  as  Augustine  says  (Epist.  xlviii.)  Nevertheless, 
nothing  of  Holy  Scripture  perishes  on  account  of  this,  since 
nothing  necessary  to  faith  is  contained  under  the  spiritual 
sense  which  is  not  elsewhere  put  forward  by  the  Scripture 
in  its  literal  sense. 

Reply  Ohj.  2.  These  three — history,  etiology,  analogy — ■ 
are  grouped  under  the  literal  sense.  For  it  is  called  history, 
as  Augustine  expounds  (loc.  cit.),  whenever  anything  is 
simply  related ;  it  is  called  etiology  when  its  cause  is  assigned, 
as  when  Our  Lord  gave  the  reason  why  Moses  allowed  the 
putting  away  of  wives — namely,  on  account  of  the  hard- 
ness of  men's  hearts;  it  is  called  analogy  whenever  the 
truth  of  one  text  of  Scripture  is  shown  not  to  contradict 
the  truth  of  another.  Of  these  four,  allegory  alone  stands 
for  the  three  spiritual  senses.  Thus  Hugh  of  S.  Victor 
(Sacram.  iv.  4  Prolog.)  includes  the  anagogical  under  the 
allegorical  sense,  laying  down  three  senses  only — the  his- 
torical, the  allegorical,  and  the  tropological. 

Reply  Ohj.  3.  The  parabolical  sense  is  contained  in  the 
literal,  for  by  words  things  are  signified  properly  and  figura- 
tively. Nor  is  the  figure  itself,  but  that  which  is  figured, 
the  literal  sense.  When  Scripture  speaks  of  God's  arm, 
the  literal  sense  is  not  that  God  has  such  a  member,  but 
only  what  is  signified  by  this  member,  namely,  operative 
power.  Hence  it  is  plain  that  nothing  false  can  ever  under- 
lie the  literal  sense  of  Holy  Writ. 


QUESTION  11. 

THE  EXISTENCE  OF  GOD. 

{In  Three  Articles.) 

Because  the  chief  aim  of  sacred  doctrine  is  to  teach  the 
knowledge  of  God,  not  only  as  He  is  in  Himself,  but  also 
as  He  is  the  beginning  of  things  and  their  last  end,  and 
especially  of  rational  creatures,  as  is  clear  from  what  has 
been  already  said,  therefore,  in  our  endeavour  to  expound 
this  science,  we  shall  treat:  (i)  Of  God:  (2)  Of  the  rational 
creature's  advance  towards   God:  (3)  Of  Christ,   Who  as 
man,  is  our  way  to  God. 
In  treating  of  God  there  will  be  a  threefold  division:— 
For  we  shall  consider  (i)  whatever  concerns  the  Divine 
Essence.     (2)  Whatever  concerns  the  distinctions  of  Persons. 
(3)  Whatever  concerns  the  procession  of  creatures  from  Him. 
Concerning  the  Divine  Essence,  we  must  consider: — 
(i)  Whether  God  exists  ?     (2)  The  manner  of  His  exist- 
ence, or,  rather,  what  is  not  the  manner  of  His  existence. 
(3)  Whatever  concerns  His  operations — namely,  His  know- 
ledge, will,  power. 

Concerning  the  first,  there  are  three  points  of  inquiry: — 

(i)  Whether  the  proposition  '  God  exists  '  is  self-evident  ? 

(2)  Whether  it  is  demonstrable  ?     (3)  Whether  God  exists  ? 

First  Article, 
whether  the  existence  of  god  is  self-evident  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  the  existence  of  God  is  sell-      \ 
evident.     Now  those  things  are  said  to  be  self-evident  to  us- 
the  knowledge  of  which  is  naturally  implanted  in  us,  as- 

19 


Q.  2.  Art.  i        THE  "  SUMMA  'i  HEOLOGICA  "  20 

we  can  see  in  regard  to  first  principles.  But  as  Damascene 
says  (De  Fid.  Orth.  i.  i,  3),  the  knowledge  of  God  is  naturally 
implanted  in  all.  Therefore  the  existence  of  God  is  self- 
evident. 

Ohj.  2.  Further,  those  things  are  said  to  be  self-evident 
which  are  known  as  soon  as  the  terms  are  known,  which  the 
Philosopher  (i  Poster,  iii.)  says  is  true  of  the  first  principles 
of  demonstration.  Thus,  when  the  nature  of  a  whole  and 
of  a  part  is  known,  it  is  at  once  recognized  that  every  whole 
(is  greater  than  its  part.  But  as  soon  as  the  signification  of 
the  word  *  God '  is  understood,  it  is  at  once  seen  that  God 
exists.  For  by  this  word  is  signified  that  thing  than  wiiich 
nothing  greater  can  be  conceived.  But  that  which  exists 
actually  and  mentally  is  greater  than  that  which  exists 
nly  mentally.  Therefore,  since  as  soon  as  the  word 
*  God  *  is  understood  it  exists  mentally,  it  also  follows 
t^d.t  it  exists  actually.  Therefore  the  proposition  '  God 
exists '  is  self-evident. 

Ohj.  3.  Further,  the  existence  of  truth  is  self-evident. 
For  whoever  denies  the  existence  of  truth  grants  that 
truth  does  not  exist :  and,  if  truth  does  not  exist,  then  the 
proposition  '  Truth  does  not  exist '  is  true :  and  if  there  is 
anything  true,  there  must  be  truth.  But  God  is  truth 
itself:  /  am  the  way,  the  truth,  and  the  life  (John  xiv.  6). 
Therefore  '  God  exists'  is  self-evident. 

On  the  contrary,  No  one  can  mentally  admit  the  opposite 
of  what  is  self-evident;  as  the  Philosopher  (Metaph.  iv., 
lect.  vi.)  states  concerning  the  first  principles  of  demon- 
stration. But  the  opposite  of  the  proposition  '  God  is' 
can  be  mentally  admitted:  The  fool  said  in  his  heart, 
There  is  no  God  (Ps.  Iii.  i).  Therefore,  that  God  exists  is 
not  self-evident. 

/  answer  that,  A  thing  can  be  self-evident  in  either  of 
two  ways;  on  the  one  hand,  self-evident  in  itself,  though 
not  to  us;  on  the  other,  self-evident  in  itself,  and  to  us. 
A  proposition  is  self-evident  because  the  predicate  is  in- 
cluded in  the  essence  of  the  subject,  as  '  Man  is  an  animal,' 
for  animal  is  contained  in  the  essence  of  man.    If,  therefore. 


21  THE  EXISTENCE  OF  GOD        Q.  2.  Art.  i 

the  essence  of  the  predicate  and  subject  be  known  to  all, 
the  proposition  will  be  self-evident  to  all;  as  is  clear  with 
regard  to  the  first  principles  of  demonstration,  the  terms  of 
which  are  common  things  that  no  one  is  ignorant  of,  such 
as  being  and  non-being,  whole    and   part,   and    suchlike. 
^  If,  however,  there  are  some  to  whom  the  essence  of  the 
predicate  and  subject  is  unknown,  the  proposition  will  be 
self-evident  in  itself,  but  not  to  those  who  do  not  know  the 
meaning  of  the  predicate  and  subject  of  the  proposition. 
Therefore,  it  happens,  as  Boethins  says  (Hebdom.,  the  title  of 
which  is  : '  Whether  all  that  is,  is  good '),  *  that  there  are  some 
mental  concepts  self-evident  only  to  the  learned,  as  that 
incorporeal  substances  are  not  in  space.'     Therefore  I  say  ; 
that  this  proposition,  '  God  exists,'  of  itself  is  self-evident;^  I 
for  the  predicate  is  the  same  as  the  subject;  because  God-i^  V 
is  His  own  existence  as  will  be  hereafter  shown  (Q.  III.,  A.  4).  ]  /\ 
Now  because  we  do  hot  know  the  essence  of  God,  the  pro- 
position is  not  self-evident  to  us;  but  needs  to  be  demon- 
strated by  things  that  are  more  known  to  us,  though  less 
known  in  their  nature — namely,  by  effects. 

Reply  Ob],  i.  To  know  that  God  exists  in  a  general 
and  confused  way  is  implanted  in  us  bj'  nature,  inasmuch 
as  God  is  man's  beatitude.  For  man  naturally  desires 
happiness,  and  what  is  naturally  desired  by  man  must 
be  naturally  known  to  him.  This,  however,  is  not  to  know 
absolutely  that  God  exists;  just  as  to  know  that  some- 
one is  approaching  is  not  the  same  as  to  know  that  Peter 
is  approaching,  even  though  it  is  Peter  who  is  approaching ; 
for  many  there  are  who  imagine  that  man's  perfect  good 
which  is  happiness,  consists  in  riches,  and  others  in  pleasures, 
and  others  in  something  else. 

Reply  Obj.  2.  Perhaps  not  everyone  who  hears  this  word 
*  God '  understands  it  to  signify  something  than  which 
nothing  greater  can  be  thought,  seeing  that  some  have 
believed  God  to  be  a  body.  Yet,  granted  that  everyone 
understands  that  by  this  word  '  God  '  is  signified  something 
than  which  nothing  greater  can  be  thought,  nevertheless, 
it  does  not  therefore  follow  that  he  understands  that  what 


Q.  2.  Art.  2       THE  "  SUMMA  THEOLOGICA  "  22 

the  word  signifies  exists  actually,  but  only  that  it  exists 
mentally.  Nor  can  it  be  argued  that  it  actually  exists, 
unless  it  be  admitted  that  there  actually  exists  something 
thati  which  nothing  greater  can  be  thought ;  and  this  precisely 
is  not  admitted  by  those  who  hold  that  God  does  not  exist.

Second  Article, 
whether  it  can  be  demonstrated  that  god  exists  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  the  existence  of  God  cannot 
be  demonstrated.  For  it  is  an  article  of  faith  that  God 
exists.  But  what  is  of  faith  cannot  be  demonstrated, 
because  a  demonstration  produces  scientific  knowledge; 
whereas  faith  is  of  the  unseen  (Heb.  xi.  i).  Therefore  it 
cannot  be  demonstrated  that  God  exists. 

Ohj.  2.  Further,  the  essence  is  the  middle  term  of  demon- 
stration. But  we  cannot  know  in  what  God's  essence 
consists,  but  solely  in  what  it  does  not  consist ;  as  Dama- 
scene says  (De  Fid.  Orth.  i.  4.).  Therefore  we  cannot  de- 
monstrate that  God  exists. 

Ohj.  3.  Further,  if  the  existence  of  God  were  demon- 
strated, this  could  only  be  from  His  effects.  But  His 
effects  are  not  proportionate  to  Him,  since  He  is  infinite 
and  His  effects  are  finite ;  and  between  the  finite  and  infinite 
there  is  no  proportion.  Therefore,  since  a  cause  cannot  be 
demonstrated  by  an  effect  not  proportionate  to  it,  it  seems 
that  the  existence  of  God  cannot  be  demonstrated. 

On  the  contrary,  The  Apostle  says:  The  invisible  things 
oj  Him  are  clearly  seen,  heing  understood  by  the  things  that 
are  made  (Rom.  i.  20).  But  this  would  not  be  unless  the 
existence  of  God  could  be  demonstrated  through  the  things 
that  are  made ;  for  the  first  thing  we  must  know  of  anything 
is,  whether  it  exists. 

/  answer  that.  Demonstration  can  be  made  in  two  ways: 
One  is  through  the  cause,  and  is  called  a  priori,  and  this 


23  THE  EXISTENCE  OF  GOD        Q.  2.  Art.  2 

is  to  argue  from  what  is  prior  absolutely.  The  other  is 
through  the  effect,  and  is  called  a  demonstration  a  pos- 
teriori; this  is  to  argue  from  what  is  prior  relatively  only 
to  us.  When  an  effect  is  better  known  to  us  than  its  cause, 
IfonTthe  efiect  we  proceed  to  the  knowledge  of  the  cause. 
And  from  every  effect  the  existence  of  its  proper  cause 
can  be  demonstrated,  so  long  as  its  effects  are  better 
known  to  us;  because  since  every  e^ect  depends  upon  — 
its  cause,  if^the  effect  exists,  the  cau§^  must  pre-exist. 
Hence  the  existence  of  God,  in  so  far  as  it  is  not  self-evident 
to  us,  can  be  demonstrated  from  those  of  His  effects  which 
are  known  to  us.  "" 

Reply  Obj.  i.  The  existence  of  God  and  other  like  truths 
about  God,  which  can  be  known  by  natural  reason,  are 
not  articles  of  faith,  but  are  preambles  to  the  articles;  for 
f^ith  presupposes  natural  knowledge,  even  as  grace  pre- 
supposes nature,  and  perfection  supposes  something  that   ^^1 
can  be  perfected.     Nevertheless,  there  is  nothing  to  prevent  '''\' 
a  man,  who  cannot  grasp  a  proof,  accepting,  as  a  matter 
of   faith,   something  which  in  itself  is  capable  of   being j-^ 
scientifically  known  and  demonstrated.  -^ 

Reply  Obj.  2.  When  the  existence  of  a  cause  is  demon- 
strated from  an  effect,  this^effect  jtakes„,.the  place  of  the 
definition  of  ,lhe-  cause-  in  proof  of  the  cause's  existence. 
This  is  especially  the  case  in  regard  to  God,  because,  in 
order  to  prove  the  existence  of  anything,  it  is  necessary 
to  accept  as  a  middle  term  the  meaning  of  the  word,  and 
not  its  essence,  for  the  question  of  its  essence  follows  oh 
the  question  of  its  exist enceTrNow  the  names  given  to  God 
are  derived  from  His  effects^;  consequently,  in  demon- 
strating the  existence  of  God  from  His  effects,  we  may  take 
for  the  middle  term  the  meaning  of  the  word  *  God  .' 

Reply  Obj.  3.  From  effects  not  proportionate  to  the 
cause  jio  perfect,  .knowledge  of  that  cause  can  be  obtained. 
Yet  from  every  effect  the  existence  of  the  cause  can  be 
clearly  demonstrated,  and  ^~we~  can  demonstrate  the 
existence  of  God  from  His  effects ;  though  from  them  we 
cannot  perfectly  know  God  as  He  is  in  His  essence.

Third  Article. 
''  whether  god  exists  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  1.  It  seems  that  God  does  not  exist;  because 
if  one  of  two  contraries  be  infinite,  the  other  would  ,,be 
altogether  destroyed.  But  the  word  '  God '  means  that 
He  is  infinite  goodness.  If,  therefore,  God  existed,  there 
would  be  no  evil  discoverable;  but  there  is  evil  in  the  world.  ^ 
Therefore  God  does  not  exist. 

Obj.  2.  Further,  it  is  superfluous  to  suppose  that  what 
can  be  accounted  for  by  a  few  principles  has  been  pro- 
duced by  many.  But  it  seems  that  everything  we  see 
in  the  world  can  be  accounted  for  by  other  principles, 
supposing  God  did  not  exist.  For  all  natural  things  can 
be  reduced  to  one  principle,  which  is  nature;  and  all 
voluntary  things  can  be  reduced  to  one  principle,  which 
is  human  reason,  or  will.  Therefore  there  is  no  need  to  '| 
suppose  God's  existence.  i 

On  the  contrary,  It  is  said  in  the  person  of  God:  /  am  Who    * 
am  (Exod.  iii.  14). 

/  answer  that,  The  existence  of  God  can  be  proved  in  five 
ways. 
•,  The  first  and  more  manifest  way  is  the  argument  from 
motion.  It  is  certain,  and  evident  to  our  senses,  that  in  the 
world  some  things  are  in  motion.  Now  whatever  is  in 
motion  is  put  in  motion  by  another,  for  nothing  can  be  in 
motion  except  it  is  in  potentiality  to  that  towards  which  it  is 
in  motion;  whereas  a  thing  moves  inasmuch  as  it  is  in 
act.  For  motion  is  nothing  else  than  the  reduction  of 
something  from  potentiality  to  actuality.  But  nothing 
I;  can  be  reduced  from  potentiality  to  actuality,  except 
Lby  something  in  a  state  of  actuality.  Thus  that  which 
is  actually  hot,  as  fire,  makes  wood,  which  is  potentially 
hot,  to  be  actually  hot,  and  thereby  moves  and  changes 
it.  Now  it  is  not  possible  that  the  same  thing  should 
bel  at   once   in   actuality    and   potentiality   in   the   same 


25  THE  EXISTENCE  OF  GOD      Q.  2.  Art.  3 

respect,   but    only   in   different    respects.      For    what    is 
actually  hot    cannot    simultaneously  be   potentially   hot; 
but  it  is  simultaneously  potentially  cold.      It  is  therefore^ 
impossible   that   in   the   same   respect   and   in   the   same  I 
way  a  thing  should  be  both  mover  and  moved,  i.e.,  that  \ 
it  should  move  itself.     Therefore,  whatever  is  in  motiori 
must   be  put   in  motion  by  another.     If  that  by  which 
it  is  put  in  motion  be  itself  put    in   motion,  then   this 
also  must  needs  be  put  in  motion  by  another,  and  that 
by  another  again.     But  this  cannot  go  on  to  infinity, 
because  then  there  would  be  no  first  mover,  and,  conse- 
quently, no  other  mover;  seeing  that  subsequent  movers 
move  only  inasmuch  as  they  are  put  in  motion  by  the  first 
•mover;  as  the  staff  moves  only  because  it  is  put  in  motion 
by  the  hand.      Therefore  it  is  necessary  to  arrive  at  a  first 
mover,  put  in  motion  by  no  other;  and  this  everyone  under- 
b^stands  to  be  God.  ^' 
^g^  Jhe  second  way  is  from  the  nature  of  the  efiicient  cause. (2) 

he  world  of  sense  we  find  there  is  an  order  of  efficient 
causes.  There  is  no  case  known  (neither  is  it,  indeed, 
ipossible)  in  which  a^thing  is  found  to  be  the  efficient  cause 
of  itself;  for  so  it  would  be  prior  to  itself,  which  is  impossible.^ 
Now  in  efficient  causes  it  is  not  possible  to  go  on  to  infinity, 
because  in  all  efficient  causes  following  in  order,  the  first  is 
the  cause  of  the  intermediate  cause,  and  the  intermediate 
is  the  cause  of  the  ultimate  cause,  whether  the  intermediate 
cause  be  sjjj^eral,  or  one  only.  Now  to  take  away  the  cause 
js  to^take, a^ayjhe.^£e.ct.  TheFefore,Tf  there  be  no  first 
cause  among  efficient  causes,  there  will  be  no  ultimate,  nor 
any  intermediate  cause.  But  if  in  efiicient  causes  it  is 
possible  to  go  on  to  infinity,  there  will  be  no  first  efficient 
cause,  neither  will  there  be  an  ultimate  effect,  nor  any  inter- 
mediate efficient  causes;  all  of  which  is  plainly  false.  There- 
fore it  is  necessary  to  admit  a  first  efficient  cause,  to  which 
everyone  gives  the  name  of  God. 

The  third  way  is  taken  from  possibility  and  necessity,  ^ 
and  runs  thus.    We  find  in  nature  things  that  are  possible  to 
be  and  not  to  be,  since  they  are  found  to  be  generated,  and 


Q.  2.  Art.  3        THE  "  SUMMA  THEOLOGICA  "  26 

to  corrupt,  and  consequently,  they  are  possible  to  be  and 
not  to  be.  But  it  is  impossible  for  these  always  to  exist, 
for  that  which  is  possible  not  to  be,  at  some  time  is  not. 
Therefore,  if  everything  isjossible  not  to  be,  then  at 
one  time  there  could  have  been  nothing  in  existence. 
Now  if  this  were  true,  even  now  there  would  be  nothing 
in  existence,  because  that  which  does  not  exist  only 
^begins  to  exist  by  something  already  existing.  Therefore, 
_if  at  one  time  nothing  was  in  existence,  it  would  have 
been  impossible  for  anything  to  have  begun  to  exist;  and 
thus  even  now  nothing  would  be  in  existence — which  is 
\  absurd.  Therefore,  not  all  beings  are  merely  possible,  but 
there  must  exist  something  the  existence  of  which  is  neces- 
sary. But  every  necessary  thing  either  has  its  necessity 
caused  by  another,  or  not.  Now  it  is  impossible  to  go  on 
to  infinity  in  necessary  things  which  have  their  necessity 
caused  by  another,  as  has  been  already  proved  in  regard 
±0  efficient  causes.  Therefore  we  cannot  but  postulate 
tlie  existence  of  some  being  having  of  itself  its  own  neces- 
sity, and  not  receiving  it  from  another,  but  rather  ^causing 
in  others  their  necessity.    This  all  men  speak  of  as  God. 

The  fourth  way  is  taken  from  the  gradation  to  be  found 
in  things.    Among  beings  there  are  some  more  and  some 
less  good,   true,   noble,   and  the  like.     But   '  more '   and 
'  less '  are  predicated  of  different  things,  according  as  they 
resemble  in  their  different  ways  something  which  is  the 
maximum,  as  a  thing  is  said  to  be  hotter  according  as  it 
more  nearly  resembles  that  which  is  hottest ;  so  that  there  is 
something    which    is    truest,    something    best,    something 
noblest,  and,  consequently,  something  which  is  uttermost 
being ;  for  those  things  that  are  greatest  in  truth  are  great- 
est  in  being,  as  it  is  written   in   Metaph.   ii.     Now  the 
j maximum  in  any  genus  is  the  cause  of  all  in  that  genus;  as 
fire,  which  is  the  maximum  of  heat,  is  the  cause  of  all  hot 
[]  things.  ^Therefore  there  must  also  be  something  which  is 
'to  all  beings  the  cause  of  their  being,  goodness,  and  every 
lother  perfection ;  and  this  we  call  God. 

The  fifth  way  is  taken  from  the  governance  of  the  world. 


27  THE  EXISTENCE  OF  GOD        Q.  2.  Art.  3 

We  see  that  things  which  lack  intelligence,  such  as  natural 
bodies,  act  for  an  end,  and  this  is  evident  from  their  acting 
always,  or  nearly  always,  in  the  same  way,  so  as  to  obtain 
the  best  result.  Hence  it  is  plain  that  not  fortuitously, 
but  designedly,  do  they  achieve  their  end.  Now  whatever 
lacks  intelligence  cannot  move  towards  an  end,  unless  it 
be  directed  by  some  being  endowed  with  knowledge  and 
intelligence;  as  the  arrow  is  shot  to  its  mark  by  the  archer^ 
Therefore  some  intelligent  being  exists  by  whom  all  natural! 
things  are  directed  to  their  end ;  and  this  being  we  call  GodM- 

Reply  Ohj.  i.  As  Augustine  says  [Enchir.  xi.) :  Since  God  is 
the  highest  good.  He  would  not  allow  any  evil  to  exist  in  His 
works,  unless  His  omnipotence  and  goodness  were  such  as  to 
bring  good  even  out  of  evil.  This  is  part  of  the  infinite  good- 
ness of  God,  that  He  should  allow  evil  to  exist,  and  out  of  it 
produce  good. 

Reply  Ohj.  2.  Since  nature  works  for  a  determinate  end 
under  the  direction  of  a  higher  agent,  whatever  is  done 
by  nature  must  needs  be  traced  back  to  God,  as  to  its  first 
cause.  So  also  whatever  is  done  voluntarily  must  also  be 
traced  back  to  some  higher  cause  other  than  human  reason 
or  will,  since  these  can  change  and  fail ;  for  all  things  that  are 
changeable  and  capable  of  defect  must  be  traced  back  to  an 
immovable  and  self-necessary  first  principle,  as  was  shown 
in  the  body  of  the  Article. 


QUESTION  III. 

OF  THE  SIMPLICITY  OF  GOD. 
{In  Eight  Articles.) 

When  the  existence  of  a  thing  has  been  ascertained  there 
remains  the  further  question  of  the  manner  of  its  existence, 
in  order  that  we  may  know  its  essence.  Now,  because 
we  cannot  know  what  God  is,  but  rather  what  He  is  not, 
we  have  no  means  for  considering  how  God  is,  but  rather 
how  He  is  not. 

Therefore,  we  must  consider  (i)  How  He  is  not :  (2)  How 
He  is  known  by  us :  (3)  How  He  is  named. 

Now  it  can  be  shown  how  God  is  not,  by  denying  of  Him 
whatever  is  opposed  to  the  idea  of  Him — viz.,  composition, 
motion,  and  the  like.  Therefore  (i)  we  must  discuss  His 
simpHcity,  whereby  we  deny  composition  in  Him:  and 
because  whatever  is  simple  in  material  things  is  imperfect 
and  a  part  of  something  else,  we  shall  discuss  (2)  His 
perfection :  (3)  His  infinity :  (4)  His  immutability :  (5)  His 
unit  37. 

Concerning  His  simplicity,  there  are  eight  points  of 
inquiry:  (i)  Whether  God  is  a  body  ?  (2)  Whether  He  is 
composed  of  matter  and  form  ?  (3)  Whether  in  Him 
there  is  composition  of  quiddity,  essence  or  nature, 
and  subject  ?  (4)  Whether  He  is  composed  of  essence 
and  existence  ?  (5)  Whether  He  is  composed  of  genus 
and  difference  ?  (6)  Whether  He  is  composed  of  sub- 
ject and  accident  ?  (7)  Whether  He  is  in  any  way 
composite,  or  wholly  simple  ?  (8)  Whether  He  enters 
into  composition  with  other  things  ? 

28 


29  THE  SIMPLICITY  OF  GOD        Q.  3.  Art.  1 

First  Article, 
whether  god  is  a  body  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  God  is  a  body.  For  a  body 
is  that  which  has  the  three  dimensions.  But  Holy  Scripture 
attributes  the  three  dimensions  to  God,  for  it  is  written: 
He  is  higher  than  Heaven,  and  what  wilt  thou  do  ?  He 
is  deeper  than  Hell,  and  how  wilt  thou  know  ?  The  measure 
of  Him  is  longer  than  the  earth  and  broader  than  the  sea  (Job 
xi.  8,  9) .    Therefore  God  is  a  body. 

Obj.  2.  Further,  everything  that  has  figure  is  a  body, 
since  figure  is  a  quahty  of  quantity.  But  God  seems  to 
have  figure,  for  it  is  written:  Let  us  make  7nan  to  our 
image  and  likeness  (Gen.  i.  26).  Now  a  figure  is  called  an 
image,  according  to  the  text:  Who  being  the  brightness  of 
His  glory  and  the  figure  i.e.,  the  image  of  His  substance 
(Heb.  i.  3).     Therefore  God  is  a  body. 

Obj.  3.  Further,  whatever  has  corporeal  parts  is  a  body. 
Now  Scripture  attributes  corporeal  parts  to  God.  Hast  thou 
an  arm  like  God  ?  (Job  xl.  4) ;  and  The  eyes  of  the  Lord  are  upon 
the  just  (Ps.  xxxiii.  16) ;  and  The  right  hand  of  the  Lord  hath 
wrought  strength  (Ps.  cxvii.  16).    Therefore  God  is  a  body. 

Obj.  4.  Further,  posture  belongs  only  to  bodies.  But 
something  which  supposes  posture  is  said  of  God  in  the 
Scriptures:  /  saw  the  Lord  sitting  (Isa.  vi.  i),  and  He  standeth 
up  to  judge  (Isa.  iii.  13).     Therefore  God  is  a  body. 

Obj.  5.  Further,  only  bodies  or  things  corporeal  can  be 
a  local  term  wherefrom  or  whereto.  But  in  the  Scriptures 
God  is  spoken  of  as  a  local  term  whereto,  according  to 
the  words,  Come  ye  to  Him  and  be  enlightened  (Ps.  xxxiii.  6), 
and  as  a  term  wherefrom:  All  they  that  depart  from  Thee  shall 
be  written  in  the  earth  (Jer.  xvii.  13).  Therefore  God  is  a 
body. 

On  the  contrary,  It  is  written  in  the  Gospel  of  St.  John 
(iv.  24) :  God  is  a  spirit. 

I  answer  that,  It  is  absolutely^true  that  God  is  not  a  body; 


Q.  3.  Art.  i      THE  "  SUMMA  THEOLOGICA  "  30 

and  this  can  be  shown  in  three  ways.  First,  because  no 
body  is  in  motion  unless  it  be  put  in  motion,  as  is  evident 
from  induction.  Now  it  has  been  akeady  proved  (Q.  ii.,,. 
A.  3),  that  God  is  the  First  Mover,  and  is  Himself  unmoved.l  • 
Therefore  it  is  clear  that  God  is  not  a  body.  Secondly, 
because  the  first  being  must  of  necessity  be  in  act,  and  in  no 
way  in  potentiality.  For  although  in  any  single  tiling  that 
passes  from  potentiality  to  actuality,  the  potentiality  is  prior 
in  time  to  the  actuality;  nevertheless,  absolutely  speaking, 
actuality  is  prior  to  potentiality;  for  whatever  is  in  poten- 
tiahty  can  be  reduced  into  actuality  only  by  some  being 
in  actuality.  Now  it  has  been  already  proved  that  God 
is  the  First  Being.  It  is  therefore  impossible  that  in  God 
there  should  be  any  potentiality.  But  every  body  is  in 
potentiaUty,  because  the  continuous,  as  such  is  divisible 
to  infinity;  it  is  therefore  impossible  that  God  should 
be  a  body.  Thirdly,  because  God  is  the  most  noble 
of  beings.  Now  it  is  impossible  for  a  body  to  be  the 
most  noble  of  beings;  for  a  body  must  be  either  animate 
or  inanimate;  and  an  animate  body  is  manifestly  nobler 
than  any  inanimate  body.  But  an  animate  body  is  not 
animate  precisely  as  body;  otherwise  all  bodies  would 
be  animate.  Therefore  its  animation  depends  upon  some 
other  thing,  as  our  body  depends  for  its  animation  on  the 
soul.  Hence  that  by  which  a  body  becomes  animated  must 
be  nobler  than  the  body.  Therefore  it  is  impossible  that 
God  should  be  a  body. 

Reply  Obj.  i.  As  we  have  said  above  (Q.  i.,  A.  9,),  Holy 
Writ  puts  before  us  spiritual  and  divine  things  under  the 
comparison  of  corporeal  things.  Hence,  when  it  attributes 
to  God  the  three  dimensions  under  the  comparison  of  cor- 
poreal quantity,  it  implies  His  virtual  quantity;  thus,  by 
depth,  it  signifies  His  power  of  knowing  hidden  things ;  by 
height,  the  transcendence  of  His  excelling  power;  by  length, 
the  duration  of  His  existence;  by  breadth.  His  act  of 
love  for  all.  Or,  as  says  Dionysius  {Div.  Nom.  ix.),  by  the 
depth  of  God  is  meant  the  incomprehensibihty  of  His  essence, 
by  length,  the  procession  of  His  all-pervading  power,  by 


31  THE  SIMPLICITY  OF  GOD        Q.  3.  Art.  2 

breadth,  His  overspreading  all  things,  inasmuch  as  all  things 
lie  under  His  protection. 

Reply  Obj.  2.  Man  is  said  to  be  after  the  image  of  God, 
not  as  regards  his  body,  but  as  regards  that  whereby  he 
excels  other  animals.  Hence,  when  it  is  said,  Let  us  make 
man  to  our  image  and  likeness,  it  is  added.  And  let  him  have 
dominion  over  the  fishes  of  the  sea  (Gen.  i.  26).  Now  man 
excels  all  animals  by  his  reason  and  intelligence;  hence 
it  is  according  to  his  intelHgence  and  reason,  which  are 
incorporeal,  that  man  is  said  to  be  according  to  the  image 
of  God. 

Reply  Obj.  3.  Corporeal  parts  are  attributed  to  God  in 
Scripture  on  account  of  His  actions,  and  this  is  owing  to 
a  certain  parallel.  For  instance  the  act  of  the  eye  is  to  see; 
hence  the  eye  attributed  to  God  signifies  His  power  of  seeing 
intellectually,  not  sensibly ;  and  so  on  with  the  other  parts. 

Reply  Obj.  4.  Whatever  pertains  to  posture,  also,  is 
only  attributed  to  God  by  some  sort  of  parallel.  He  is 
spoken  of  as  sitting,  on  account  of  His  unchangeableness 
and  dominion;  and  as  standing,  on  account  of  His  power 
of  overcoming  whatever  withstands  Him. 

Reply  Obj.  5.  We  draw  near  to  God  by  no  corporeal 
steps,  since  He  is  everywhere,  but  by  the  affections  of  our 
soul,  and  by  the  actions  of  that  same  soul  do  we  withdraw 
from  Him ;  thus,  to  draw  near  or  to  withdraw  signifies  merely 
spiritual  actions  based  on  the  metaphor  of  local  motion. 

Second  Article, 
whether  god  is  composed  of  matter  and  form  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  God  is  composed  of  matter 
and  form.  For  whatever  has  a  soul  is  composed  of  matter 
and  form;  since  the  soul  is  the  form  of  the  body.  But  Scrip- 
ture attributes  a  soul  to  God;  for  it  is  mentioned  in  Hebrews 
(x.  38),  where  God  says:  But  My  just  man  liveth  by  faith; 
but  if  he  withdraw  himself,  he  shall  ?wt  please  My  soul.  There- 
fore God  is  composed  of  matter  and  form. 


Q.  3.  Art.  2       THE  ''  SUMMA  THEOLOGICA  "  32 

Ohj,  2.  Further,  anger,  joy,  and  the  Hke  are  passions 
of  the  composite.  But  these  are  attributed  to  God  in 
Scripture:  The  Lord  was  exceeding  angry  with  His  people 
(Ps.  cv.  40) .  Therefore  God  is  composed  of  matter  and  form. 
Obj.  3.  Further,  matter  is  the  principle  of  individuali- 
zation. But  God  seems  to  be  individual,  for  He  cannot 
be  predicated  of  many.  Therefore  He  is  composed  of  matter 
and  form. 

On  the  contrary,  Whatever  is  composed  of  matter  and 
form  is  a  body ;  for  dimensive  quantity  is  the  first  property 
of  matter.    But  God  is  not  a  body  as  proved  in  the  preceding 
Article;  therefore  He  is  not  composed  of  matter  and  form. 
/  answer  that,  It  is  impossible  that  matter  should  exist 
A   in  God.     First,  because  matter  is  in  potentiality.     But 
•^'    we  have  shown  (Q.  ii.,  A.  3)  that  God  is  pure  act,  with- 
out any  potentiality.    Hence  it  is  impossible  that  God 
should  be  composed  of  matter  and  form.     Secondly,  because 
everything  composed  of  matter  and  form  owes  its  perfection 
and  goodness  to  its  form;  therefore  its  goadness  is  partici- 
pated, inasmuch  as  matter  participates  the  form.    Now  the 
first  good  and  the  best — viz.  God — is  not  a  participated  good, 
because  the  essential  good  is  prior  to  the  participated  good. 
Hence  it  is  impossible  that  God  should  be  composed  of 
matter  and  form.     Thirdly,  because  every  agent  acts  by 
its  form;  hence  the  manner  in  which  it  has  its  form  is  the 
manner  in  which  it  is  an  agent.     Therefore  whatever  is 
primarily  and  essentially  an  agent  must  be  primarily  and 
^-essentially  form.     Now  God  is  the  first  agent,  since  He  is 
1    the  first  efficient  cause.     He  is  therefore  of  His  essence 
\   a  form;  and  not  composed  of  matter  and  form. 

Reply  Ohj.  i.  A  soul  is  attributed  to  God  because  His 
acts  resemble  the  acts  of  a  soul;  for,  that  we  will  anything, 
is  due  to  our  soul.  Hence  what  is  pleasing  to  His  will  is 
said  to  be  pleasing  to  His  soul. 

Reply  Ohj  2.  Anger  and  the  like  are  attributed  to  God 
on  account  of  a  simihtude  of  effect.  Thus,  because  to 
punish  is  properly  the  act  of  an  angry  man,  God's  punish- 
ment is  metaphorically  spoken  of  as  His  anger. 


33  THE  SIMPLICITY  OF  GOD        Q.  3.  Art.  3 

Reply  Ohj.  3.  Forms  which  can  be  received  in  matter  are 
individualized  by  matter,  which  cannot  be  in  another  as 
in  a  subject  since  it  is  the  first  underlying  subject;  although 
form  of  itself,  unless  something  else  prevents  it,  can  be 
received  by  many.  But  that  form  which  cannot  be  received 
in  matter,  but  is  self-subsisting,  is  individualized  precisely 
because  it  cannot  be  received  in  a  subject;  and  such  a  form 
is  God.    Hence  it  does  not  follow  that  matter  exists  in  God 


Third  Article, 
whether  god  is  the  same  as  his  essence  or  nature  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  God  is  not  the  same  as  His 
essence  or  nature.  For  nothing  can  be  in  itself.  But  the 
substance  or  nature  of  God — i.e.,  the  Godhead — is  said  to 
be  in  God.  Therefore  it  seems  that  God  is  not  the  same  as 
His  essence  or  nature. 

Ohj.  2.  Further,  the  effect  is  assimilated  to  its  cause;  for 
every  agent  produces  its  like.  But  in  created  things  the 
suppositum  is  not  identical  with  its  nature ;  for  a  man  is  not 
the  same  as  his  humanity.  Therefore  God  is  not  the  same 
as  His  Godhead. 

On  the  contrary,  It  is  said  of  God  that  He  is  life  itself, 
and  not  only  that  He  is  a  living  thing :  /  am  the  way,  the 
truth,  and  the  life  (John  xiv.  6) .  Now  the  relation  between 
Godhead  and  God  is  the  same  as  the  relation  between  life 
and  a  living  thing.    Therefore  God  is  His  very  Godhead. 

/  answer  that,  God  is  the  same  as  His  essence  or  nature. 
To  understand  this,  it  must  be  noted  that  in  things  com- 
posed of  matter  and  form,  the  nature  or  essence  must 
differ  from  the  suppositum,  because  the  essence  or  nature 
connotes  only  what  is  included  in  the  definition  of  the 
species;  as,  humanity  connotes  all  that  is  included  in  the 
definition  of  man,  for  it  is  by  this  that  man  is  man,  and  it 
is  this  that  humanity  signifies,  that,  namely,  whereby  man 
is  man.  Now  individual  matter,  with  all  the  individualizing 
accidents,  is  not  included  in  the  definition  of  the  species.

For  this  particular  flesh,  these  bones,  this  blackness  or 
whiteness,  etc.,  are  not  included  in  the  definition  of  a  man. 
Therefore  this  flesh,  these  bones,  and  the  accidental  qualities 
distinguishing  this  particular  matter,  are  not  included  in 
humanity;  and  yet  they  are  included  in  the  thing  which 
is  a  man.  Hence  the  thing  which  is  a  man  has  something 
more  in  it  than  has  humanity.  Consequently  humanity 
and  a  man  are  not  wholly  identical ;  but  humanity  is  taken 
to  mean  the  formal  part  of  a  man,  because  the  principles 
whereby  a  thing  is  defined  are  regarded  as  the  formal 
constituent  in  regard  to  the  individualizing  matter.  On 
the  other  hand,  in  things  not  composed  of  matter  and  form, 
in  which  individualization  is  not  due  to  individual  matter 
— that  is  to  say,  to  this  matter — the  very  forms  being 
individualized  of  themselves, — it  is  necessary  the  forms 
themselves  should  be  subsisting  supposita.  Therefore  sup- 
positum  and  nature  in  them  are  identified.  Since  God 
then  is  not  composed  of  matter  and  form.  He  must  be  His 
own  Godhead,  His  own  Life,  and  whatever  else  is  thus 
predicated  of  Him. 

Reply  Ohj.  i.  We  can  speak  of  simple  things  only  as 
though  they  were  like  the  composite  things  from  which 
we  derive  our  knowledge.  Therefore,  in  speaking  of  God, 
we  use  concrete  nouns  to  signify  His  subsistence,  because 
with  us  only  those  things  subsist  which  are  composite;  and 
we  use  abstract  nouns  to  signify  His  simplicity.  In  saying 
therefore  that  Godhead,  or  life,  or  the  like  are  in  God,  we 
indicate  the  composite  way  in  which  our  intellect  under- 
stands, but  not  that  there  is  any  composition  in  God. 

Reply  Ohj.  2.  The  effects  of  God  do  not  imitate  Him 
perfectly,  but  only  as  far  as  they  are  able ;  and  the  imitation 
is  here  defective,  precisely  because  what  is  simple  and  one, 
can  only  be  represented  by  divers  things;  consequently 
composition  is  accidental  to  them,  and  therefore  in  them 
suppositum  is  not  the  same  as  nature. 


35  THE  SIMPLICITY  OF  GOD        Q.  3.  Art.  4 


Fourth  Article. 
whether  essence  and  existence  are  the  same 

IN   GOD  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  essence  and  existence  are  not 
the  same  in  God.  For  if  it  be  so,  then  the  divine  being 
has  nothing  added  to  it.  Now  being  to  which  no  addition 
is  made  is  universal  being  which  is  predicated  of  all  things. 
Therefore  it  foUows  that  God  is  being  in  general  which  can 
be  predicated  of  everything.  But  this  is  false:  For  men 
gave  the  incommunicable  name  to  stones  and  wood  (Wisd. 
xiv.  21).    Therefore  God's  existence  is  not  His  essence. 

Obj.  2.  Further,  we  can  know  whether  God  exists  as  said 
above  (Q.  II.,  A.  2) ;  but  we  cannot  know  what  He  is.  There- 
fore God's  existence  is  not  the  same  as  His  essence — that  is, 
as  His  quiddity  or  nature. 

On  the  contrary,  Hilary  says  (Trin.  vii.) :  In  God  existence 
is  not  an  accidental  quality,  but  subsisting  truth.  Therefore 
what  subsists  in  God  is  His  existence. 

/  answer  that,  6od  is  not  only  His  own  essence,  as  shown  ■ 
in  the  preceding  article,  but  also  His  own  existence.  This 
may  be  shown  in  several  ways.  First,  whatever  a  thing  has 
besides  its  essence  must  be  caused  either  by  the  constituent 
principles  of  that  essence  (like  a  property  that  necessarily 
accompanies  the  species — as  the  faculty  of  laughing  is 
proper  to  a  man — and  is  caused  by  the  constituent  principles 
of  the  species),  or  by  some  exterior  agent, — as  heat  is  caused 
in  water  by  fire.  Therefore,  if  the  existence  of  a  thing  differs 
from  its  essence,  this  existence  must  be  caused  either  by 
some  exterior  agent  or  by  its  essential  principles.  Now 
it  is  impossible  for  a  thing's  existence  to  be  caused  by  its 
essential  constituent  principles,  for  nothing  can  be  the 
sufficient  cause  of  its  own  existence,  if  its  existence  is 
caused.  Therefore  that  thing,  whose  existence  differs 
from  its  essence,  must  have  its  existence  caused  by 
another.     But  this  cannot  be  true  of  God;  because  we  call 


Q.  3.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  36 

God  the  first  efficient  cause.  Therefore  it  is  impossible 
that  in  God  His  existence  should  differ  from  His  essence. 
Secondly,  existence  is  that  which  makes  every  form  or 
nature  actual;  for  goodness  and  humanity  are  spoken  of  as 
actual,  only  because  they  are  spoken  of  as  existing.  There- 
fore, existence  must  be  compared  to  essence,  if  the  latter 
is  a  distinct  reality,  as  actuality  to  potentiality.  There- 
fore, since  in  God  there  is  no  potentiality,  as  shown  above 
(A.  i),  it  follows  that  in  Him  essence  does  not  differ  from 
existence.  Therefore  His  essence  is  His  existence.  Thirdly, 
because,  just  as  that  which  has  fire,  but  is  not  itself  fire,  is 
on  fire  by  participation ;  so  that  which  has  existence  but  is 
not  existence,  is  a  being  by  participation.  But  God  is  His 
own  essence,  as  shown  above  (A.  3) ;  if,  therefore.  He  is  not 
His  own  existence  He  will  be  not  essential,  but  participated 
being.  He  will  not  therefore  be  the  first  being — which  is 
absurd.  Therefore  God  is  His  own  existence,  and  not 
merely  His  own  essence. 

Reply  Obj,  i.  A  thing  that  has  nothing  added  to  it  can 
be  of  two  kinds.  Either  its  essence  precludes  any  addition  ; 
thus,  for  example,  it  is  of  the  essence  of  an  irrational  animal 
to  be  without  reason.  Or  we  may  understand  a  thing  to 
have  nothing  added  to  it,  inasmuch  as  its  essence  does  not 
require  that  anything  should  be  added  to  it ;  thus  the  genus 
animal  is  without  reason,  because  it  is  not  of  the  essence 
of  animal  in  general  to  have  reason ;  but  neither  is  it  to  lack 
reason.  And  so  the  divine  being  has  nothing  added  to  it 
in  the  first  sense ;  whereas  universal  being  has  nothing  added 
to  it  in  the  second  sense. 

Reply  Obj.  2.  To  be  can  mean  either  of  two  things.  It 
may  mean  the  act  of  essence,  or  it  may  mean  the  com- 
position of  a  proposition  effected  by  the  mind  in  joining 
a  predicate  to  a  subject.  Taking  to  be  in  the  first  sense, 
we  cannot  understand  God's  existence  nor  His  essence; 
but  only  in  the  second  sense.  We  know  that  this  proposi- 
tion which  we  form  about  God  when  we  say  God  is,  is 
true;  and  this  we  know  from  His  effects  (Q.  II.,  A.  2). 


37  THE  SIMPLICITY  OF  GOD       Q.  3  Apt  5 

Fifth  Article, 
whether  god  is  contained  in  a  genus  ? 

We  proceed  thus  to  the  Fifth  Article  : — 

Objection  1.  It  seems  that  God  is  contained  in  a  genus. 
For  a  substance  is  a  being  that  subsists  of  itself.  But  this 
is  especially  true  of  God.  Therefore  God  is  in  the  genus  of 
substance. 

Obj.  2.  Further,  nothing  can  be  measured  save  by  some- 
thing of  its  own  genus;  as  length  is  measured  by  length 
and  numbers  by  number.  But  God  is  the  measure  of  all 
substances,  as  the  Commentator  shows  (Metaph.  x.).  There- 
fore God  is  in  the  genus  of  substance. 

On  the  contrary,  In  the  mind,  genus  is  prior  to  what  it 
contains.  But  nothing  is  prior  to  God  either  really  or 
mentally.    Therefore  God  is  not  in  any  genus. 

/  answer  that,  A  thing  can  be  in  a  genus  in  two  ways; 
either  absolutely  and  properly,  as  a  species  contained  under 
a  genus;  or  as  being  reducible  to  it,  as  principles  and  pri- 
vations. For  example,  a  ptint  ami  unity  are  reduced  to 
the  genus  of  quantity,  as  its  principles;  while  blindness 
and  all  other  privations  are  reduced  to  the  genus  of  habit. 
But  in  neither  way  is  God  in  a  genus.  That  He  cannot 
be  a  species  of  any  genus  may  be  shown  in  three  ways. 
First,  because  a  species  is  constituted  of  genus  and  difference. 
Now  that  from  which  the  difference  constituting  the  species 
is  derived,  is  always  related  to  that  from  which  the  genus  is 
derived,  as  actuality  is  related  to  potentiality.  For  animal 
is  derived  from  sensitive  nature,  by  concretion  as  it  were, 
for  that  is  animal,  which  has  a  sensitive  nature.  Rational 
being,  on  the  other  hand,  is  derived  from  intellectual  nature, 
because  that  is  rational,  which  has  an  intellectual  nature, 
and  intelligence  is  compared  to  sense,  as  actuality  is  to 
potentiality.  The  same  argument  holds  good  in  other 
things.  Hence  since  in  God  actuality  is  not  added  to 
potentiality,  it  is  impossible  that  He  should  be  in  any  genus 
as  a  species.     Secondly,  since  the  existence  of  God  is  His 


Q.  3.  Art.  5    THE  ''  SUMMA  THEOLOGICA  "  38 

essence,  if  God  were  in  any  genus,  He  would  be  in  the  genus 
*  being,'  because,  since  genus  is  predicated  as  an  essential 
it  refers  to  the  essence  of  a  thing.  But  the  Philosopher  has 
shown  {Metaph.  iii.)  that  being  cannot  be  a  genus,  for  every 
genus  has  differences  distinct  from  its  generic  essence. 
Now  no  difference  can  exist  distinct  from  being;  for  non- 
being  cannot  be  a  difference.  It  follows  then  that  God  is 
not  in  a  genus.  Thirdly,  because  all  in  one  genus  agree  in 
the  quiddity  or  essence  of  the  genus  which  is  predicated 
of  them  as  an  essential,  but  they  differ  in  their  existence. 
For  the  existence  of  man  and  of  horse  is  not  the  same;  as 
also  of  this  man  and  that  man :  thus  in  every  member  of  a 
genus,  existence  and  quiddity — i.e.,  essence — must  differ. 
But  in  God  they  do  not  differ,  as  shown  in  the  preceding 
article.  Therefore  it  is  plain  that  God  is  not  in  a  genus 
as  if  He  were  a  species.  From  this  it  is  also  plain  that  He 
has  no  genus  nor  difference,  nor  can  there  be  any  definition 
of  Him;  nor,  save  through  His  effects,  a  demonstration  of 
Him:  for  a  definition  is  from  genus  and  difference;  and 
the  mean  of  a  demonstration  is  a  definition.  That  God 
is  not  in  a  genus,  as  reducible  to  it  as  its  principle,  is 
clear  from  this,  that  a  principle  reducible  to  any  genus 
does  not  extend  beyond  that  genus;  as,  a  point  is  the  prin- 
ciple of  continuous  quantity  alone;  and  unity,  of  discon- 
tinuous quantity.  But  God  is  the  principle  of  all  being. 
Therefore  He  is  not  contained  in  any  genus  as  its  principle. 

Reply  Obj.  i.  The  word  substance  signifies  not  only  what 
exists  of  itself — for  existence  cannot  of  itself  be  a  genus, 
as  shown  in  the  body  of  the  article;  but,  it  also  signifies  an 
essence  that  has  the  property  of  existing  in  this  way — -namely, 
of  existing  of  itself;  this  existence,  however,  is  not  its  essence. 
Thus  it  is  clear  that  God  is  not  in  the  genus  of  substance. 

Reply  Obj.  2.  This  objection  turns  upon  proportionate 
measure;  which  must  be  homogeneous  with  what  is 
measured.  Now,  God  is  not  a  measure  proportionate  to 
anything.  Still,  He  is  called  the  measure  of  all  things,  in 
the  sense  that  everything  has  being  only  according  as  it 
resembles  Him.

Sixth  Article. 

whether  in  god  there  are  any  accidents? 

We  proceed  thus  to  the  Sixth  Article  : — ■ 
Objection  i.  It  seems  that  there  are  accidents  in  God. 
For  substance  cannot  be  an  accident,  as  Aristotle  says 
{Physic,  i.).  Therefore  that  which  is  an  accident  in  one, 
cannot,  in  another,  be  a  substance.  Thus  it  is  proved  that 
heat  cannot  be  the  substantial  form  of  fire,  because  it  is 
an  accident  in  other  things.  But  wisdom,  virtue,  and  the 
like,  which  are  accidents  in  us,  are  attributes  of  God.  There- 
fore in  God  there  are  accidents. 

Obj.  2.  Further,  in  every  genus  there  is  a  first  principle. 
But  there  are  many  genera  of  accidents.  If,  therefore,  the 
primal  members  of  these  genera  are  not  in  God,  there  will  be 
many  primal  beings  other  than  God — which  is  absurd. 

On  the  contrary,  Every  accident  is  in  a  subject.  But  God 
cannot  be  a  subject,  for  no  simple  form  can  be  a  subject,  as 
Boethius  says  [De  Trinit).  Therefore  in  God  there  cannot 
be  any  accident. 

/  answer  that,  From  all  we  have  said,  it  is  clear  there  can 
be  no  accident  in  God.  First,  because  a  subject  is  compared 
to  its  accidents  as  potentiality  to  actuality;  for  a  subject  is 
in  some  sense  made  actual  by  its  accidents.  But  there  can 
be  no  potentiality  in  God,  as  was  shown  Q.  XL,  A.  3. 
Secondly,  because  God  is  His  own  existence;  and  as  Boe- 
thius says  (De  Hebdom.),  although  every  essence  may  have 
something  superadded  to  it,  this  cannot  apply  to  abso- 
lute being:  thus  a  heated  substance  can  have  something 
extraneous  to  heat  added  to  it,  as  whiteness,  nevertheless 
absolute  heat  can  have  nothing  else  than  heat.  Thirdly, 
because  what  is  essential  is  prior  to  what  is  accidental. 
Whence  as  God  is  absolute  primal  being,  there  can  be  in 
Him  nothing  accidental.  Neither  can  He  have  any  essential 
accidents  (as  the  capability  of  laughing  is  an  essential 
accident  of  man),  because  such  accidents  are  caused  by  the 
constituent  principles  of  the  subject.     Now  there  can  be 


Q.  3.  Art.  7     THE  "  SUMMA  THEOLOGICA  "  40 

nothing  caused  in  God,  since  He  is  the  first  cause.  Hence 
it  follows  that  there  is  no  accident  in  God. 

Reply  Obj.  i.  Virtue  and  wisdom  are  not  predicated  of 
God  and  of  us  univocally.  Hence  it  does  not  follow  that 
there  are  accidents  in  God  as  there  are  in  us. 

Reply  Obj.  2.  Since  substance  is  prior  to  its  accidents, 
the  principles  of  accidents  are  reducible  to  the  principles 
of  the  substance  as  to  that  which  is  prior;  although  God 
is  not  first  as  if  contained  in  the  genus  of  substance;  yet 
He  is  first  in  respect  to  all  being,  outside  of  every  genus. 


Seventh  Article, 
whether  god  is  altogether  simple  ? 

We  proceed  thus  to  the  Seventh  Article : — 

Objection  i.  It  seems  that  God  is  not  altogether  simple. 
For  whatever  is  from  God  must  imitate  Him.  Thus  from 
the  first  being  are  all  beings;  and  from  the  first  good  is  all 
good.  But  in  the  things  which  God  has  made,  nothing 
is  altogether  simple.  Therefore  neither  is  God  altogether 
simple. 

Obj.  2.  Further,  whatever  is  best  must  be  attributed  to 
God.  But  with  us  that  which  is  composite  is  better  than 
that  which  is  simple;  thus,  chemical  compounds  are  better 
than  simple  elements,  and  animals  than  the  parts  that  com- 
pose them.  Therefore  it  cannot  be  said  that  God  is  alto- 
gether simple. 

On  the  contrary,  Augustine  says  {De  Trin.  iv.  6,  7) :  God 
is  truly  and  absolutely  simple. 

I  answer  that,  The  absolute  simplicity  of  God  may  be 
shown  in  many  ways.  First,  from  the  previous  articles  of 
this  question.  For  there  is  neither  composition  of  quanti- 
tative parts  in  God,  since  He  is  not  a  body ;  nor  composition 
of  form  and  matter;  nor  does  His  nature  differ  from  His 
suppositum ;  nor  His  essence  from  His  existence;  neither  is 
there  in  Him  composition  of  genus  and  difference,  nor  of 
subject  and  accident.    Therefore,  it  is  clear  that  God  is 


41  THE  SIMPLICITY  OF  GOD        Q.  3.  Art.  7 

nowise  composite,  but  is  altogether  simple.  Secondly, 
because  every  composite  is  posterior  to  its  component  parts, 
and  is  dependent  on  them;  but  God  is  the  first  being,  as 
shown  above  (Q.  II.,  A.  3) .  Thirdly,  because  every  composite 
has  a  cause,  for  things  in  themselves  different  cannot  unite 
unless  something  causes  them  to  unite.  But  God  is  uncaused, 
as  shown  above  {loc.  cit),  since  He  is  the  first  efficient  cause. 
Fourthly,  because  in  every  composite  there  must  be  poten- 
tiality and  actuality ;  but  this  does  not  apply  to  God ;  for 
either  one  of  the  parts  actuates  another,  or  at  least  all  the 
parts  are  potential  to  the  whole.  Fifthly,  because  nothing 
composite  can  be  predicated  of  any  single  one  of  its  parts. 
And  this  is  evident  in  a  whole  made  up  of  dissimilar  parts ; 
for  no  part  of  a  man  is  a  man,  nor  any  of  the  parts  of  the 
foot,  a  foot.  But  in  wholes  made  up  of  similar  parts,  although 
something  which  is  predicated  of  the  whole  may  be  predicated 
of  a  part  (as  a  part  of  the  air  is  air,  and  a  part  of  water, 
water),  nevertheless  certain  things  are  predicable  of  the  whole 
which  cannot  be  predicated  of  any  of  the  parts;  for  instance, 
if  the  whole  volume  of  water  is  two  cubits,  no  part  of  it  can 
be  two  cubits.  Thus  in  every  composite  there  is  something 
which  is  not  it  itself.  But,  even  if  this  could  be  said  of 
whatever  has  a  form,  viz.,  that  it  has  something  which  is 
not  it  itself,  as  in  a  white  object  there  is  something  which 
does  not  belong  to  the  essence  of  white;  nevertheless  in  the 
form  itself,  there  is  nothing  besides  itself.  And  so,  since 
God  is  absolute  form,  or  rather  absolute  being,  He  can  be  in 
no  way  composite.  Hilary  implies  this  argument,  when  he 
says  {De  Trin.  vii.) :  God,  Who  is  strength,  is  not  made  up  of 
things  that  are  weak;  nor  is  He  Who  is  light,  composed  of  things 
that  are  dim. 

Reply  Obj.  i.  Whatever  is  from  God  imitates  Him,  as 
caused  things  imitate  the  first  cause.  But  it  is  of  the 
essence  of  a  thing  caused  to  be  in  some  sort  composite; 
because  at  least  its  existence  differs  from  its  essence,  as  will 
be  shown  hereafter,  (Q.  IV.  A.  3) . 

Reply  Obj.  2.  With  us  composite  things  are  better  than 
simple  things,  because  the  perfections  of  created  goodness 


Q.  3.  Art.  8    THE  "  SUMMA  THEOLOGICA  "  42 

cannot  be  found  in  one  simple  thing,  but  in  many  things. 
But  the  perfection  of  divine  goodness  is  found  in  one  simple 
thing  (QQ.  IV.,  A.  i,  and  VI.,  A.  2). 

Ebghth  Article, 
whether  god  enters  into  the  composition  of  other 

THINGS  ? 

We  proceed  thus  to  the  Eighth  Article  : — 

Objection  i.  It  seems  that  God  enters  into  the  composition 
of  other  things,  for  Dionysius  says  [Ccel.  Hier.  iv.) :  The 
being  of  all  things  is  that  which  is  above  being — the  Godhead. 
But  the  being  of  all  things  enters  into  the  composition  of 
everything.  Therefore  God  enters  into  the  composition 
of  other  things. 

Obj.  2.  Further,  God  is  a  form;  for  Augustine  says 
{De  Verb.  Dom.'^)  that,  the  word  of  God,  which  is  God,  is 
an  uncreated  form.  But  a  form  is  part  of  a  compound. 
Therefore  God  is  part  of  some  compound. 

Obj.  3.  Further,  whatever  things  exist,  in  no  way  differ- 
ing from  each  other,  are  the  same.  But  God  and  primary 
matter  exist,  and  in  no  way  differ  from  each  other.  There- 
fore they  are  absolutely  the  same.  But  primary  matter 
enters  into  the  composition  of  things.  Therefore  also  does 
God.  Proof  of  the  minor — whatever  things  differ,  they 
differ  by  some  differences,  and  therefore  must  be  composite. 
But  God  and  primary  matter  are  altogether  simple.  There- 
fore they  nowise  differ  from  each  other. 

On  the  contrary,  Dionysius  says  {Div.  Nom.  ii.) :  There 
can  be  no  touching  Him,  i.e.,  God,  nor  any  other  union  with 
Him  by  mingling  part  with  part. 

Further,  the  first  cause  rules  all  things  without  com- 
mingling with  them,  as  the  Philosopher  says  {De  Causis). 

I  answer  that,  On  this  point  there  have  been  three  errors. 
Some  have  affirmed  that  God  is  the  world-soul,  as  is  clear 
from  Augustine  (De  Civit.  Dei  vii.  6).  This  is  practically 
the  same  as  the  opinion  of  those  who  assert  that  God  is  the  soul 
of  the  highest  heaven.     Again,  others  have  said  that  God  is 

*  Serm.  xxxviii. 


43  THE  SIMPLICITY  OF  GOD        Q.  3.  Art.  8 

the  formal  principle  of  all  things;  and  this  was  the  theory 
of  the  Almaricians.     The  third  error  is  that  of  David  of 
Dinant,  who  most  absurdly  taught  that  God  was  primary 
matter.     Now  all  these  contain  manifest  untruth ;  since  it  is 
not  possible  for  God  to  enter  into  the  composition  of  any- 
thing,  either  as  a  formal  or  a  material  principle.     First, 
because  God  is  the  first  efficient  cause.     Now  the  efficient 
cause  is  not  identical  numerically  with  the  form  of  the 
thing  caused,  but  only  specffically:  for  man  begets  man. 
But  primary  matter  can  be  neither  numerically  nor  specifi- 
cally identical  with  an  efficient  cause;  for  the  former  is 
merely   potential,    while   the   latter   is   actual.     Secondly, 
because,  since  God  is  the  first  efficient  cause,  to  act  belongs 
to  Him  primarily  and  essentially.     But  that  which  enters 
into  composition  with  anything  does  not  act  primarily  and 
essentially,  but  rather  the  composite  so  acts;  for  the  hand 
does  not  act,  but  the  man  by  his  hand;  and,  fire  warms  by 
its   heat.     Hence   God   cannot   be   part   of   a   compound. 
Thirdly,  because  no  part  of  a  compound  can  be  absolutely 
primal  among  beings — not  even  matter,  nor  form,  though 
they  are  the  primal  parts  of  every  compound.     For  matter 
is  merely  potential;  and  potentiality  is  absolutely  posterior 
to  actuality,  as  is  clear  from  the  foregoing  (Q.  III.,  A.  i) : 
while  a  form  which  is  part  of  a  compound  is  a  participated 
form;  and  as  that  which  participates  is  posterior  to  that 
which  is  essential,  so  likewise  is  that  which  is  participated; 
as  fire  in  ignited  objects  is  posterior  to  fire  that  is  essen- 
tially such.     Now  it  has  been  proved  that  God  is  absolutely 
primal  being  (Q.  II.,  A.  3). 

Reply  Obj.  i.  The  Godhead  is  called  the  being  of  all 
things,  as  their  efficient  and  exemplar  cause,  but  not  as 
being  their  essence. 

Reply  Obj.  2.  The  Word  is  an  exemplar  form;  but  not  a 
form  that  is  part  of  a  compound. 

Reply  Obj.  3.  Simple  things  do  not  differ  by  added 
differences, — for  this  is  the  property  of  compounds.  Thus 
man  and  horse  differ  by  their  differences,  rational  and 
irrational;  which  differences,  however,  do  not  differ  from 


Q.  3.  Art.  8    THE  "  SUMMA  THEOLOGICA  "  44 

each  other  by  other  differences.  Hence,  to  be  quite  ac- 
curate, it  is  better  to  say  that  they  are,  not  different,  but 
diverse.  Hence,  according  to  the  Philosopher  (Metaph.  x.), 
things  which  are  diverse  are  absolutely  distinct,  hut  things 
which  are  different  diff^er  by  something,.  Therefore,  strictly 
speaking,  primary  matter  and  God  do  not  differ,  bi^t  are 
by  their  very  being  diverse.  Hence  it  does  not  follow  they 
are  the  same. 


gUESTION  IV. 

THE  PERFECTION  OF  GOD. 
{In  Three  Articles.) 

Having  considered  the  divine  simplicity,  we  treat  next  of 
God's  perfection.  Now  because  everything  in  so  far  as  it  is 
perfect  is  called  good,  we  shall  speak  first  of  the  divine  per- 
fection ;  secondly  of  the  divine  goodness. 

Concerning  the  first  there  are  three  points  of  inquiry : — 
(i)  Whether  God  is  perfect  ?     (2)  Whether  God  is  perfect 
universally,   as  having  in  Himself  the  perfections  of  all 
things  ?     (3)  Whether  creatures  can  be  said  to  be  like  God  ? 

First  Article, 
whether  god  is  perfect  ? 

We  proceed  thus  to  the  First  Article : — 

Objection  i.  It  seems  that  perfection  does  not  belong  to 
God.  For  we  say  a  thing  is  perfect  if  it  is  completely  made. 
But  it  does  not  befit  God  to  be  made.  Therefore  He  is 
not  perfect. 

Ohj.  2.  Further,  God  is  the  first  beginning  of  things.  But 
the  beginnings  of  things  seem  to  be  imperfect,  as  seed  is  the 
beginning  of  animal  and  vegetable  life.  Therefore  God  is 
imperfect. 

Ohj.  3.  Further,  as  shown  above  (Q.  HI.,  A.  4),  God's 
essence  is  existence.  But  existence  seems  most  imperfect, 
since  it  is  most  universal  and  receptive  of  all  modification. 
Therefore  God  is  imperfect. 

On  the  contrary,  It  is  written :  Be  you  perfect  as  also  your 
heavenly  Father  is  perfect  (Matt.  v.  48). 

/  answer  that,  As  the  Philosopher  relates  (Metaph.  xii.), 

A5 


Q.  4.  Art.  i    THE  "  SUMMA  THEOLOGICA  "  46 

some  ancient  philosophers,  namely,  the  Pythagoreans,  and 
Leucippus,  did  not  predicate  best  and  most  perfect  of  the 
first  principle.  The  reason  was  that  the  ancient  philo- 
sophers considered  only  a  material  principle;  and  a  material 
principle  is  most  imperfect.  For  since  matter  as  such  is 
merely  potential,  the  first  material  principle  must  be  simply 
potential,  and  thus  most  imperfect.  Now  God  is  the  first 
principle,  not  material,  but  in  the  order  of  efficient  cause, 
which  must  be  most  perfect.  For  just  as  matter,  as  such, 
is  merely  potential,  an  agent,  as  such,  is  in  the  state  of 
actuality.  Hence,  the  first  active  principle  must  needs  be 
most  actual,  and  therefore  most  perfect;  for  a  thing  is 
perfect  in  proportion  to  its  state  of  actuality,  because  we 
call  that  perfect jwhich  lacks  nothing  of  the  mode  of  its 
perfection.  '" 

Reply  Obj.  1.  As  Gregory  says  (Moral,  v,  26,  29):  Though 
our  lips  can  only  stammer,  we  yet  chant  the  high  things  of  God. 
For  that  which  is  not  made  is  improperly  called  perfect. 
Nevertheless  because  created  things  are  then  called 
perfect,  when  from  potentiality  they  are  brought  into 
actuality,  this  word  perfect  signifies  whatever  is  not  want- 
ing in  actuality,  whether  this  be  by  way  of  perfection, 
or  not. 

Reply  Obj.  2.  The  material  principle  which  with  us  is 
found  to  be  imperfect,  cannot  be  absolutely  primal;  but 
must  be  preceded  by  something  perfect.  For  seed,  though 
it  be  the  principle  of  animal  life  reproduced  through  seed,  has 
previous  to  it,  the  animal  or  plant  from  which  it  came. 
Because,  previous  to  that  which  is  potential,  must  be  that 
which  is  actual;  since  a  potential  being  can  only  be  reduced 
into  act  by  some  being  already  actual. 

Reply  Obj.  3.  Existence  is  the  most  perfect  of  all  things, 
for  it  is  compared  to  all  things  as  that  by  which  they  are 
made  actual;  for  nothing  has  actuality  except  so  far  as  it 
exists.  Hence  existence  is  that  which  actuates  all  things, 
even  their  forms.  Therefore  it  is  not  compared  to  other 
things  as  the  receiver  is  to  the  received ;  but  rather  as  the 
received  to  the  receiver.     When  therefore  I  speak  of  the 


47  THE  PERFECTION  OF  GOD       Q.  4.  Art.  2 

existence  of  man,  or  horse,  or  anything  else,  existence  is 
considered  a  formal  principle,  and  as  something  received; 
and  not  as  that  which  exists. 


Second  Article, 
whether  the  perfections  of  all  things  are  in  god  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  the  perfections  of  all  things  are 
not  in  God.  For  God  is  simple,  as  shown  above  (Q.  III.,  A.  7) ; 
whereas  the  perfections  of  things  are  many  and  diverse. 
Therefore  the  perfections  of  all  things  are  not  in  God. 

Obj.  2.  Further,  opposites  cannot  coexist.  Now  the  per- 
fections of  things  are  opposed  to  each  other,  for  each 
thing  is  perfected  by  its  specific  difference.  But  the  dif- 
ferences by  whidoi  genera  are  divided,  and  species  constituted, 
are  opposed  to  each  other.  Therefore,  because  opposites 
cannot  coexist  in  the  same  subject,  it  seems  that  the  per- 
fections of  all  things  are  not  in  God. 

Obj.  3.  Further,  a  living  thing  is  more  perfect  than  what 
merely  exists;  and  an  intelUgent  thing  than  what  merely 
lives.  Therefore,  life  is  more  perfect  than  existence;  and 
knowledge  than  life.  But  the  essence  of  God  is  existence 
itself.  Therefore  He  has  not  the  perfections  of  life,  and 
knowledge,  and  other  similar  perfections. 

On  the  contrary,  Dionysius  says  {Div.  Nom.  v.)  that  God 
in  His  one  existence  prepossesses  all  things, 

I  answer  that,  All  created  perfections  are  in  God.  Hence 
He  is  spoken  of  as  universally  perfect,  because  He  lacks 
not  (says  the  Commentator,  Metaph.  v.)  any  excellence 
which  may  be  found  in  any  genus.  This  may  be  seen  from 
two  considerations.  First,  because  whatever  perfection 
exists  in  an  effect  must  be  found  in  the  effective  cause; 
either  in  the  same  formality,  if  it  is  a  univocal  agent — as 
when  man  reproduces  man;  or  in  a  more  eminent  degree, 
if  it  is  an  equivocal  agent — thus  in  the  sun  is  the  likeness 
of  whatever  is  generated  by  the  sun's  power.  Now  it  is 
plain  that  the  effect   pre-exists    virtually  in  the  efficient 


Q.  4.  Art.  2    THE  '*  SUMMA  THEOLOGICA  "  48 

cause:  and  although  to  pre-exist  in  the  potentiality  of  a 
material  cause  is  to  pre-exist  in  a  more  imperfect  way, 
since  matter  as  such  is  imperfect,  and  an  agent  as  such  is 
perfect;  still  to  pre-exist  virtually  in  the  efficient  cause 
is  to  pre-exist  not  in  a  more  imperfect,  but  in  a  more  perfect 
way.  Since  therefore  God  is  the  first  effective  cause  of 
things,  the  perfections  of  all  things  must  pre-exist  in  God 
in  a  more  eminent  way.  Dionysius  implies  the  same  line 
of  argument  by  saying  of  God  {Div.  Norn,  v.) :  It  is  not  that 
He  is  this  and  not  that,  hut  that  He  is  all,  as  the  cause  of  all. 
/Secondly;  from  what  has  been  already  proved,  God  is 
['  existence  itself,  of  itself  subsistent  (Q.  III.,  A.  4).  Conse- 
quently, He  must  contain  within  Himself  the  whole  per- 
1  fection  of  being.  For  it  is  clear  that  if  some  hot  thing  has 
not  the  whole  perfection  of  heat,  this  is  because  heat  is  not 
participated  in  its  full  perfection ;  but  if  this  heat  were  self- 
subsisting,  nothing  of  the  virtue  of  heat  would  be  wanting 
to  it.  Since  therefore  God  is  subsisting  being  itself, 
nothing  of  the  perfection  of  being  can  be  wanting  to  Him. 
Now  all  created  perfections  are  included  in  the  perfection 
of  being ;  for  things  are  perfect,  precisely  so  far  as  they  have 
being  after  some  fashion.  It  follows  therefore  that  the 
perfection  of  no  one  thing  is  wanting  to  God.  This  line  of 
argument,  too,  is  implied  by  Dionysius  [loo.  cit),  when  he 
says  that,  God  exists  not  in  any  single  mode,  but  embraces 
all  being  within  Himself,  absolutely,  without  limitation,  uni- 
formly; and  afterwards  he  adds  that,  He  is  the  very  existence 
to  subsisting  things. 

Reply  Obj.  i.  Even  as  the  sun  (as  Dionysius  remarks, 
loc.  cit.),  while  remaining  one  and  shining  uniformly,  contains 
within  itself  first  and  uniformly  the  substances  of  sensible 
things,  and  many  and  diverse  quahties;  a  fortiori  should 
all  things  in  a  kind  of  natural  unity  pre-exist  in  the  cause  of 
all  things ;  and  thus  things  diverse  and  in  themselves  opposed 
to  each  other,  pre-exist  in  God  as  one,  without  injury  to 
His  simphcity. 

This  suffices  for  the  Reply  to  the  Second  Objection. 

Reply  Obj,  3.  The  same  Dionysius  says  (loc.  cit.)  that, 


49  THE  PERFECTION  OF  GOD      Q.  4.  Art.  3 

although  existence  is  more  perfect  than  Hfe,  and  life  than 
wisdom,  if  they  are  considered  as  distinguished  in  idea; 
nevertheless,  a  living  thing  is  more  perfect  than  what 
merely  exists,  because  living  things  also  exist,  and  intelli- 
gent things  both  exist  and  live.  Although  therefore  exist- 
ence does  not  include  life  and  wisdom,  because  that  which 
participates  in  existence  need  not  participate  in  every  mode 
of  existence;  nevertheless  God's  existence  includes  in  itself 
life  and  wisdom,  because  nothing  of  the  perfection  of  being 
can  be  wanting  to  Him  who  is  subsisting  being  itself. 

Third  Article, 
whether  any  creature  can  be  like  god  ? 

We  proceed  thus  to  the  Third  Article : — 

Objection  i.  It  seems  that  no  creature  can  be  like  God. 
For  it  is  written  (Ps.  Ixxxv.  8) :  There  is  none  among  the  gods 
like  unto  Thee,  0  Lord.  But  of  all  creatures  the  most  ex- 
cellent are  those  which  are  called  by  participation  gods. 
Therefore  still  less  can  other  creatures  be  said  to  be  like 
to  God. 

Obj.  2.  Further,  likeness  implies  comparison.  But  there 
can  be  no  comparison  between  things  in  a  different  genus. 
Therefore  neither  can  there  be  any  likeness.  Thus  we 
do  not  say  that  sweetness  is  like  whiteness.  But  no  creature 
is  in  the  same  gg»9ts  as  God:  since  God  is  in  no  genus,  as 
shown  above  (Q.  III.,  A.  5) .     Therefore  no  creature  is  like  God. 

Obj.  3.  Further,  we  speak  of  those  things  as  like  which 
agree  in  form.  But  nothing  can  agree  with  God  in  form; 
for,  save  in  God  alone,  essence  and  existence  differ.  There- 
fore no  creature  can  be  like  to  God. 

Obj.  4.  Further,  among  like  things  there  is  mutual  like- 
ness; for  like  is  like  to  like.  If  therefore  any  creature  is 
like  God,  God  will  be  like  some  creature,  which  is  against 
what  is  said  by  Isaias :  To  whom  have  you  likened  God  .^  (xl.  18) . 

On  the  contrary.  It  is  written:  Let  us  make  man  to  our 
image  and  likeness  (Gen.  i.  26),  and:  When  He  shall  appear 
we  shall  be  like  to  Him  {1  John  in.  2), 

I-  4 


Q.  4.  Art.  3     THE  ''  SUMMA  THEOLOGICA  "  50 

I  answer  that,  Since  likeness  is  based  upon  agreement 
or  communication  in  form,  it  varies  according  to  the  many 
modes  of  communication  in  form.  Some  things  are  said 
to  be  like,  which  communicate  in  the  same  form  according 
to  the  same  formality,  and  according  to  the  same  mode; 
and  these  are  said  to  be  not  merely  like,  but  equal  in  their 
likeness;  as  two  things  equally  white  are  said  to  be  alike  in 
whiteness;  and  this  is  the  most  perfect  likeness.  In  another 
way,  we  speak  of  things  as  alike  which  communicate  in 
form  according  to  the  same  formality,  though  not  accord- 
ing to  the  same  measure,  but  according  to  more  or  less, 
as  something  less  white  is  said  to  be  like  another  thing  more 
white;  and  this  is  imperfect  likeness.  In  a  third  way  some 
things  are  said  to  be  alike  which  communicate  in  the  same 
form,  but  not  according  to  the  same  formality;  as  we  see 
in  non-univocal  agents.  For  since  every  agent  reproduces 
itself  so  far  as  it  is  an  agent,  and  everything  acts  according 
to  the  manner  of  its  form,  the  effect  must  in  some  way 
resemble  the  form  of  the  agent.  If  therefore  the  agent 
is  contained  in  the  same  species  as  its  effect,  there  will  be 
a  likeness  in  form  between  that  which  makes  and  that  which 
is  made,  according  to  the  same  formality  of  the  species; 
as  man  reproduces  man.  If  however  the  agent  and  its 
effect  are  not  contained  in  the  same  species,  there  will  be  a 
likeness,  but  not  according  to  the  formality  of  the  same 
species;  as  things  generated  by  the  sun's  heat  may  be  in 
some  sort  spoken  of  as  like  the  sun,  not  as  though  they 
received  the  form  of  the  sun  in  its  specific  likeness,  but 
in  its  generic  likeness.  Therefore  if  there  is  an  agent  not 
contained  in  any  genus,  its  effects  will  still  more  distantly 
reproduce  the  form  of  the  agent,  not,  that  is,  so  as  to  par- 
ticipate in  the  likeness  of  the  agent's  form  according  to  the 
same  specific  or  generic  formaUty,  but  only  according  to 
some  sort  of  analogy;  as  existence  is  common  to  all.  In 
thfs  way  all  created  things,  so  far  as  they  are  beings,  are 
like  God  as  the  first  and  universal  principle  of  all  being. 

Reply  Obj.  i.  As  Dionysius  says  (Div.  Nom.  ix.),  when 
Holy  Writ  declares  that  nothing  is  like  God,  it  does  not  mean 


51  THE  PERFECTION  OF  GOD       Q.  4.  Art.  3 

to  deny  all  likeness  to  Him.  For,  the  same  things  can  he 
like  and  unlike  to  God :  like,  according  as  they  imitate  Him, 
as  far  as  He,  Who  is  not  perfectly  imitable,  can  he  imitated; 
unlike  according  as  they  fall  short  of  their  cause,  not  merely 
in  intensity  and  remission,  as  that  which  is  less  white  falls 
short  of  that  which  is  more  white ;  but  because  they  are  not 
in  agreement,  specifically  or  generically. 

Reply  Ohj.  2.  God  is  not  related  to  creatures  as  though 
belonging  to  a  different  genus,  but  as  transcending  every 
genus,  and  as  the  principle  of  all  genera. 

Reply  Ohj,  3.  Likeness  of  creatures  to  God  is  not  affirmed 
on  account  of  agreement  in  form  according  to  the  formality 
of  the  same  genus  or  species,  but  solely  according  to  analogy, 
inasmuch  as  God  is  essential  being,  whereas  other  things  are 
beings  by  participation. 

Reply  Ohj.  4.  Although  it  may  be  admitted  that  creatures 
are  in  some  sort  like  God,  it  must  nowise  be  admitted 
that  God  is  like  creatures;  because,  as  Dionysius  says 
{Div.  Nom.  ix.) ;  A  mutual  likeness  may  he  found  hetween 
things  of  the  same  order,  hut  not  hetween  a  cause  and  that 
which  is  caused.  For,  we  say  that  a  statue  is  like  a  man, 
but  not  conversely;  so  also  a  creature  can  be  spoken  of  as 
in  some  sort  like  God ;  but  not  that  God  is  like  a  creature. 


QUESTION  V. 

OF  GOODNESS  IN  GENERAL. 

[In  Six  Articles.) 

We  next  consider  goodness  : — 

First,  goodness  in  general.  Secondly,  the  goodness  of 
God. 

Under  the  first  head  there  are  six  points  of  inquiry : — 
(i)  Whether  goodness  and  being  are  the  same  really  ? 
(2)  Granted  that  they  differ  only  in  idea,  which  is  prior  in 
thought  ?  (3)  Granted  that  being  is  prior,  whether  every 
being  is  good  ?  (4)  To  what  cause  should  goodness  be 
reduced  ?  (5)  Whether  goodness  consists  in  mode,  species, 
and  order  ?  (6)  Whether  goodness  is  divided  into  the 
virtuous,  the  useful,  and  the  pleasant  ? 

First  Article, 
whether  goodness  differs  really  from  being  ? 

We  proceed  thus  to  the  First  Article : — 

Objection  i.  It  seems  that  goodness  differs  really  from 
being.  For  Boethius  says  {De  Hehdom) :  /  perceive  that 
in  nature  the  fact  that  things  are  good  is  one  thing:  that 
they  are  is  another.  Therefore  goodness  and  being  really 
differ. 

Ohj,  2.  Further,  nothing  can  be  its  own  form.  But  that 
is  called  good  which  has  the  form  of  being,  according  to  the 
commentary  on  De  Causis.  Therefore  goodness  differs 
really  from  being. 

Obj.  3.  Further,  goodness  can  be  more  or  less.  But 
being  cannot  be  more  or  less.  Therefore  goodness  differs 
really  from  being. 

52 


53  GOODNESS  IN  GENERAL        Q.  5.  Art.  i 

On  the  contrary,  Augustine  says  {De  Doctr.  Christ,  i.  42) 
that,  inasmuch  as  we  exist  we  are  good, 

I  answer  that,  Goodness  and  being  are  really  the  same, 
and  differ  only  in  idea;  which  is  clear  from  the  following 
argument.  The  essence  of  goodness  consists  in  this,  that 
it  is  in  some  way  desirable.  Hence  the  Philosopher  says 
{Ethic,  i.) :  Goodness  is  what  all  desire.  Now  it  is  clear  that 
a  thing  is  desirable  only  in  so  far  as  it  is  perfect;  for  all 
desire  their  own  perfection.  But  everything  is  perfect  so 
far  as  it  is  actual.  Therefore  it  is  clear  that  a  thing  is  perfect 
so  far  as  it  exists;  for  it  is  existence  that  makes  all  things 
actual,  as  is  clear  from  the  foregoing  (Q.  III.,  A.  4;  Q.  IV., 
A.  i).  Hence  it  is  clear  that  goodness  and  being  are  the 
same  really.  But  goodness  presents  the  aspect  of  desir- 
ableness, which  being  does  not  present. 

Reply  Obj.  i.  Although  goodness  and  being  are  the 
same  really,  nevertheless  since  they  differ  in  thought,  they 
are  not  predicated  of  a  thing  absolutely  in  the  same  way. 
Since  being  properly  signifies  that  something  actually  is, 
and  actuality  properly  correlates  to  potentiality;  a  thing 
is,  in  consequence,  said  simply  to  have  being,  accordingly 
as  it  is  primarily  distinguished  from  that  which  is  only  in 
potentiality;  and  this  is  precisely  each  thing's  substantial 
being.  Hence  by  its  substantial  being,  everything  is  said 
to  have  being  simply;  but  by  any  further  actuaUty  it  is 
said  to  have  being  relatively.  Thus  to  be  white  implies 
relative  being,  for  to  be  white  does  not  take  a  thing  out  of 
simply  potential  being;  because  only  a  thing  that  actually 
has  being  can  receive  this  mode  of  being.  But  goodness 
signifies  perfection  which  is  desirable;  and  consequently 
of  ultimate  perfection.  Hence  that  which  has  ultimate 
perfection  is  said  to  be  simply  good;  but  that  which  has 
not  the  ultimate  perfection  it  ought  to  have  (although,  in 
so  far  as  it  is  at  all  actual,  it  has  some  perfection),  is  not  said 
to  be  perfect  simply  nor  good  simply,  but  only  relatively. 
In  this  way,  therefore,  viewed  in  its  primal  {i.e.,  substantial) 
being  a  thing  is  said  to  be  simply,  and  to  be  good  relatively 
{i.e.,  in  so  far  as  it  has  being),  but  viewed  in  its  complete 


Q.  5.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  54 

actuality,  a  thing  is  said  to  be  relatively,  and  to  be  good 
simply.  Hence  the  sajdng  of  Boethius  {loc.  cit),  I  perceive 
that  in  nature  the  fact  that  things  are  good  is  one  thing,  that 
they  are  is  another,  is  to  be  referred  to  a  thing's  goodness 
simply,  and  having  being  simply.  Because,  regarded  in 
its  primal  actuality,  a  thing  simply  exists;  and  regarded 
in  its  complete  actuality,  it  is  good  simply — in  such  sort 
that  even  in  its  primal  actuality,  it  is  in  some  sort  good, 
and  even  in  its  complete  actuality,  it  in  some  sort  has  being. 

Reply  Ohj.  2.  Goodness  is  a  form  so  far  as  absolute 
goodness  signifies  complete  actuality. 

Reply  Ohj.  3.  Again,  goodness  is  spoken  of  as  more  or 
less  according  to  a  thing's  superadded  actuality,  for  example, 
as  to  knowledge  or  virtue. 


Second  Article, 
whether  goodness  is  prior  in  idea  to  being  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  goodness  is  prior  in  idea  to 
being.  For  names  are  arranged  according  to  the  arrange- 
ment of  the  things  signified  by  the  names.  But  Dionysius 
[Div,  Nom.  iii.)  assigned  the  first  place,  amongst  other 
names  of  God,  to  His  goodness  rather  than  to  His  being. 
Therefore  in  idea  goodness  is  prior  to  being. 

Ohj.  2.  Further,  that  which  is  the  more  extensive  is  prior 
in  idea.  But  goodness  is  more  extensive  than  being, 
because,  as  Dionysius  notes  (loc.  cit.  v.),  goodness  extends 
to  things  hoth  existing  and  non-existing;  whereas  existence 
extends  to  existing  things  alone.  Therefore  goodness  is  in 
idea  prior  to  being. 

Ohj.  3.  Further,  what  is  the  more  universal  is  prior  in 
idea.  But  goodness  seems  to  be  more  universal  than  being, 
since  goodness  has  the  aspect  of  desirable ;  whereas  to  some 
non-existence  is  desirable;  for  it  is  said  of  Judas:  It  were 
better  for  him,  if  that  man  had  not  been  born  (Matt.  xxvi.  24). 
Therefore  in  idea  goodness  is  prior  to  being. 

Ohj.  4.  Further,  not  only  is  existence  desirable,  but  life, 


55  GOODNESS  IN  GENERAL         Q.  5.  Art.  2 

knowledge,  and  many  other  things  besides.  Thus  it  seems 
that  existence  is  a  particular  appetible,  and  goodness  a 
universal  appetible.  Therefore,  absolutely,  goodness  is 
prior  in  idea  to  being. 

On  the  contrary,  It  is  said  by  Aristotle  {De  Causis)  that 
the  first  of  created  things  is  being. 

I  answer  that,  In  idea  being  is  prior  to  goodness.  For 
the  meaning  signified  by  the  name  of  a  thing  is  that  which 
the  mind  conceives  of  the  thing  and  intends  by  the  word 
that  stands  for  it.  Therefore,  that  is  prior  in  idea,  which  is 
first  conceived  by  the  intellect.  Now  the  first  thing  con- 
ceived by  the  intellect  is  being ;  because  everything  is  know- 
able  only  inasmuch  as  it  is  in  actuality.  Hence,  being  is  the 
proper  object  of  the  intellect,  and  is  primarily  intelligible; 
as  sound  is  that  which  is  primarily  audible.  Therefore 
in  idea  being  is  prior  to  goodness. 

Reply  Obj.  i.  Dionysius  discusses  the  Divine  Names 
(Div.  Nom.  I,  iii.)  as  implying  some  causal  relation  in  God; 
for  we  name  God,  as  he  says,  from  creatures,  as  a  cause 
from  its  effects.  But  goodness,  since  it  has  the  aspect  of 
desirable,  impHes  the  idea  of  a  final  cause,  the  causality  of 
which  is  first  among  causes,  since  an  agent  does  not  act 
except  for  some  end;  and  by  an  agent  matter  is  moved 
to  its  form.  Hence  the  end  is  called  the  cause  of  causes. 
Thus  goodness,  as  a  cause,  is  prior  to  being,  as  is  the  end  to 
the  form.  Therefore  among  the  names  signifying  the  divine 
causality,  goodness  precedes  being.  Again,  according  to 
the  Platonists,  who,  through  not  distinguishing  primary 
matter  from  privation,  said  that  matter  was  non-being, 
goodness  is  more  extensively  participated  than  being; 
for  primary  matter  participates  in  goodness  as  tending 
to  it,  for  all  seek  their  like;  but  it  does  not  participate  in 
being,  since  it  is  presumed  to  be  non-being.  Therefore 
Dionysius  says  that  goodness  extends  to  non-existence  (loc. 
cit.  Obj.  2). 

Reply  Obj.  2.  The  same  solution  is  applied  to  this  objec- 
tion. Or  it  may  be  said  that  goodness  extends  to  existing 
and  non-existing  things,  not  so  far  as  it  can  be  predicated 


Q.  5.  Art.  3     THE  "  SUMMA  THEOLOGICA  "  56 

of  them,  but  so  far  as  it  can  cause  them — if,  indeed,  by- 
non-existence  we  understand  not  simply  those  things  which 
do  not  exist,  but  those  which  are  potential,  and  not  actual. 
For  goodness  has  the  aspect  of  the  end,  in  which  not 
only  actual  things  find  their  completion,  but  also  towards 
which  tend  even  those  things  which  are  not  actual,  but 
merely  potential.  Now  being  implies  the  habitude  of  a 
formal  cause  only,  either  inherent  or  exemplar;  and  its 
causality  does  not  extend  save  to  those  things  which  are 
actual. 

Reply  Ohj.  3.  Non-being  is  desirable,  not  of  itself,  but 
only  relatively — i.e.,  inasmuch  as  the  removal  of  an  evil, 
which  can  only  be  removed  by  non-being,  is  desirable. 
Now  the  removal  of  an  evil  cannot  be  desirable,  except 
so  far  as  this  evil  deprives  a  thing  of  some  being.  Therefore 
being  is  desirable  of  itself;  and  non-being  only  relatively, 
inasmuch  as  one  seeks  some  mode  of  being  of  which  one 
cannot  bear  to  be  deprived;  thus  even  non-being  can  be 
spoken  of  as  relatively  good. 

Reply  Ohj.  4.  Life,  wisdom,  and  the  like,  are  desirable 
only  so  far  as  they  are  actual.  Hence  in  each  one  of  them 
some  sort  of  being  is  desired.  And  thus  nothing  can  be 
desired  except  being;  and  consequently  nothing  is  good 
except  being. 

Third  Article, 
whether  every  being  is  good  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  not  every  being  is  good.  For 
goodness  is  something  superadded  to  being,  as  is  clear  from 
A.  I.  But  whatever  is  added  to  being  limits  it;  as  sub- 
stance, quantity,  quality,  etc.  Therefore  goodness  limits 
being.     Therefore  not  every  being  is  good. 

Ohj.  2.  Further,  no  evil  is  good:  Woe  to  you  that  call  evil 
good,  and  good  evil  (Isa.  v.  20).  But  some  things  are  called 
evil.     Therefore  not  every  being  is  good. 

Ohj.  3.  Further,  goodness  implies  desirability.  Now 
primary  matter   does  not   imply   desirability,   but   rather 


^y  GOODNESS  IN  GENERAL  Q.  5.  Art.  3 

that  which  desires.  Therefore  primary  matter  does  not 
contain  the  formality  of  goodness.  Therefore  not  every 
being  is  good. 

Oh].  4.  Further,  the  Philosopher  notes  {Metaph.  iii.)  that 
in  mathematics  goodness  does  not  exist.  But  mathematics 
are  entities;  otherwise  there  would  be  no  science  of  mathe- 
matics.   Therefore  not  every  being  is  good. 

On  the  contrary,  Every  being  that  is  not  God,  is  God's 
creature.  Now  every  creature  of  God  is  good  (i  Tim.  iv.  4) : 
and  God  is  the  greatest  good.     Therefore  every  being  is  good. 

I  answer  that,  Every  being,  as  being,  is  good.  For  all 
being,  as  being,  has  actuality  and  is  in  some  way  perfect; 
since  every  act  implies  some  sort  of  perfection;  and  per- 
fection implies  desirability  and  goodness,  as  is  clear  from 
A.  I.     Hence  it  follows  that  every  being  as  such  is  good. 

Reply  Obj.  i.  Substance,  quantity,  quality,  and  every- 
thing included  in  them,  limit  being  by  appljdng  it  to  some 
essence  or  nature.  Now  in  this  sense,  goodness  does  not 
add  anything  to  being  beyond  the  aspect  of  desirability  and 
perfection,  which  is  also  proper  to  being,  whatever  kind  of 
nature  it  may  be.     Hence  goodness  does  not  limit  being. 

Reply  Obj.  2.  No  being  can  be  spoken  of  as  evil,  formally  |.. 
as  being,  but  only  so  far  as  it  lacks  being.  Thus  a  man  is  " 
said  to  be  evil,  because  he  lacks  some  virtue;  and  an  eye  is  ; 
said  to  be  evil,  because  it  lacks  the  power  to  see  well. 

Reply  Obj.  3.  As  primary  matter  has  only  potential  being, 
so  is  it  only  potentially  good.  Although,  according  to  the 
Platonists,  primary  matter  may  be  said  to  be  a  non-being 
on  account  of  the  privation  attaching  to  it,  nevertheless, 
it  does  participate  to  a  certain  extent  in  goodness,  viz.,  by 
its  relation  to,  or  aptitude  for,  goodness.  Consequently, 
to  be  desirable  is  not  its  property,  but  to  desire. 

Reply  Obj.  4.  Mathematical  entities  do  not  subsist  as 
realities;  because  they  would  be  in  some  sort  good  if  they 
subsisted;  but  they  have  only  logical  existence,  inasmuch 
as  they  are  abstracted  from  motion  and  matter;  thus  they 
cannot  have  the  aspect  of  an  end,  which  itself  has  the 
aspect  of  moving  another.     Nor  is  it  repugnant  that  there 


Q.  5.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  58 

should  be  in  some  logical  entity  neither  goodness  nor  form 
of  goodness;  since  the  idea  of  being  is  prior  to  the  idea 
of  goodness,  as  was  said  in  the  preceding  article. 


Fourth  Article. 

whether  goodness  has  the  aspect  of  a 
final  cause  ? 

We  proceed  thus  to  the  Fourth  Article : — 

Objection  i.  It  seems  that  goodness  has  not  the  aspect 
of  a  final  cause,  but  rather  of  the  other  causes.  For,  as 
Dionysius  says  (Div.  Noni.  iv.),  Goodness  is  praised  as  beauty. 
But  beauty  has  the  aspect  of  a  formal  cause.  Therefore 
goodness  has  the  aspect  of  a  formal  cause. 

Obj.  2.  Further,  goodness  is  self-diffusive;  for  Dionysius 
says  (loc.  cit.)  that  goodness  is  that  whereby  all  things 
subsist,  and  are.  But  to  be  self-giving  implies  the  aspect 
of  an  efficient  cause.  Therefore  goodness  has  the  aspect 
of  an  efficient  cause. 

Obj.  3.  Further,  Augustine  says  {De  Doctr.  Christ,  i.  31) 
that  we  exist,  because  God  is  good.  But  we  owe  our  existence 
to  God  as  the  efficient  cause.  Therefore  goodness  implies 
the  aspect  of  an  efficient  cause. 

On  the  contrary,  The  Philosopher  says  (Physic,  ii.)  that 
that  is  to  be  considered  as  the  end  and  the  good  of  other  things, 
for  the  sake  of  which  something  is.  Therefore  goodness  has 
the  aspect  of  a  final  cause. 

/  answer  that,  Since  goodness  is  that  which  all  things 
desire,  and  since  this  has  the  aspect  of  an  end,  it  is  clear 
that  goodness  implies  the  aspect  of  an  end.  Nevertheless, 
the  idea  of  goodness  presupposes  the  idea  of  an  efficient 
cause,  and  also  of  a  formal  cause.  For  we  see  that  what  is 
first  in  causing,  is  last  in  the  thing  caused.  Fire,  e.g.,  heats 
first  of  all  before  it  reproduces  the  form  of  fire;  though  the 
heat  in  the  fire  follows  from  its  substantial  form.  Now  in 
causing,  goodness  and  the  end  come  first,  both  of  which 
move  the  agent  to  act;  secondly,  the  action  of  the  agent 
moving  to  the  form  ;  thirdly,   comes  the  form.     Hence 


59  GOODNESS  IN  GENERAL         Q.  5.  Art.  5 

in  that  which  is  caused  the  converse  ought  to  take  place, 
so  that  there  should  be  first,  the  form  whereby  it  is  a 
being ;  secondly,  we  consider  in  it  its  effective  power,  whereby 
it  is  perfect  in  being,  for  a  thing  is  perfect  when  it  can  repro- 
duce its  like,  as  the  Philosopher  says  (Meteor,  iv.) ;  thirdly, 
there  follows  the  formality  of  goodness  which  is  the  basic 
principle  of  its  perfection. 

Reply  Ohj.  i.  Beauty  and  goodness  in  a  thing  are  identical 
fundamentally;  for  they  are  based  upon  the  same  thing, 
namely,  the  form;  and  consequently  goodness  is  praised 
as  beauty.  But  they  differ  logically,  for  goodness  properly 
relates  to  the  appetite  (goodness  being  what  all  things 
desire);  and  therefore  it  has  the  aspect  of  an  end  (the 
appetite  being  a  kind  of  movement  towards  a  thing).  On 
the  other  hand,  beauty  relates  to  the  cognitive  faculty;  for 
beautiful  things  are  those  which  please  when  seen.  Hence 
beauty  consists  in  due  proportion ;  for  the  senses  delight  in 
things  duly  proportioned,  as  in  what  is  after  their  own 
kind — because  even  sense  is  a  sort  of  reason,  just  as  is  every 
cognitive  faculty.  Now,  since  knowledge  is  by  assimilation, 
and  similarity  relates  to  form,  beauty  properly  belongs  to 
the  nature  of  a  formal  cause. 

Reply  Ohj.  2.  Goodness  is  described  as  self-diffusive  in 
the  sense  that  an  end  is  said  to  move. 

Reply  Ohj.  3.  He  who  has  a  will  is  said  to  be  good,  so  far 
as  he  has  a  good  will;  because  it  is  by  our  will  that  we 
employ  whatever  powers  we  may  have.  Hence  a  man  is 
said  to  be  good,  not  by  his  good  understanding ;  but  by  his 
good  will.  Now  the  will  relates  to  the  end  as  to  its  proper 
object.  Thus  the  saying,  we  exist  because  God  is  good  has 
reference  to  the  final  cause. 

Fifth  Article. 

whether  the  essence  of  goodness  consists  in  mode, 

species,  and  order  ? 

We  proceed  thus  to  the  Fifth  Article  : — 
Objection  i.  It  seems  that  the  essence  of  goodness  does 
not  consist  in  mode,   species,   and  order.    For  goodness 


Q.  5.  Art.  5    THE  "  SUMMA  THEOLOGICA  "  60 

and  being  differ  logically.  But  mode,  species,  and  order 
seem  to  belong  to  the  nature  of  being,  for  it  is  written: 
Thou  hast  ordered  all  things  in  measure,  and  numher,  and  weight 
(Wis.  xi.  21).  And  to  these  three  can  be  reduced  species, 
mode,  and  order,  as  Augustine  says  {Gen.  ad  lit.  iv.  3) : 
Measure  fixes  the  mode  of  everything,  number  gives  it  its  species, 
and  weight  gives  it  rest  and  stability.  Therefore  the  essence 
of  goodness  does  not  consist  in  mode,  species,  and  order. 

Obj.  2.  Further,  mode,  species,  and  order  are  themselves 
good.  Therefore  if  the  essence  of  goodness  consists  in 
mode,  species,  and  order,  then  every  mode  must  have  its 
own  mode,  species,  and  order.  The  same  would  be  the 
case  with  species  and  order  in  endless  succession. 

Obj.  3.  Further,  evil  is  the  privation  of  mode,  species,  and 
order.  But  evil  is  not  the  total  absence  of  goodness.  There- 
fore the  essence  of  goodness  does  not  consist  in  mode, 
species,  and  order. 

Obj.  4.  Further,  that  wherein  consists  the  essence  of 
goodness  cannot  be  spoken  of  as  evil.  Yet  we  can  speak  of 
an  evil  mode,  species,  and  order.  Therefore  the  essence 
of  goodness  does  not  consist  in  mode,  species,  and  order. 

Obj.  5.  Further,  mode,  species,  and  order  are  caused  by 
weight,  number,  and  measure,  as  appears  from  the  quotation 
from  Augustine.  But  not  every  good  thing  has  weight, 
number,  and  measure;  for  Ambrose  says  {Hexam.  i.  9):  It 
is  of  the  nature  of  light  not  to  have  been  created  in  number, 
weight,  and  measure.  Therefore  the  essence  of  goodness 
does  not  consist  in  mode,  species,  and  order. 

On  the  contrary,  Augustine  says  {De  Nat.  Boni  iii.) :  These 
three — mode,  species,  order — as  common  good  things,  are  in 
everything  God  has  made;  thus,  where  these  three  abound  the 
things  are  very  good;  where  they  are  less,  the  things  are  less 
good;  where  they  do  not  exist  at  all,  there  can  be  nothing  good. 
But  this  would  not  be  unless  the  essence  of  goodness  con- 
sisted in  them.  Therefore  the  essence  of  goodness  consists 
in  mode,  species,  and  order. 

/  answer  that,  Everything  is  said  to  be  good  so  far  as  it 
is  perfect;  for  in  that  way  only  is  it  desirable  (as  shown 


6i  GOODNESS  IN  GENERAL        Q.  5.  Art.  5 

above,  AA.  i,  3).  Now  a  thing  is  said  to  be  perfect  if  it 
lacks  nothing  according  to  the  mode  of  its  perfection. 
But  since  everything  is  what  it  is  by  its  form  (and  since 
the  form  presupposes  certain  things,  and  from  the  form 
certain  things  necessarily  follow),  in  order  for  a  thing  to 
be  perfect  and  good  it  must  have  a  form,  together  with 
all  that  precedes  and  follows  upon  that  form.  Now  the 
form  presupposes  determination  or  commensuration  of 
its  principles,  whether  material  or  efficient,  and  this  is 
signified  by  the  mode:  hence  it  is  said  that  the  measure 
marks  the  mode.  But  the  form  itself  is  signified  by  the 
species;  for  everything  is  placed  in  its  species  by  its  form. 
Hence  the  number  is  said  to  give  the  species,  for  definitions 
signifying  species  are  like  numbers,  according  to  the  Philo- 
sopher [Metaph.  x.) ;  for  as  a  unit  added  to,  or  taken  from, 
a  number,  changes  its  species,  so  a  difference  added  to,  or 
taken  from,  a  definition,  changes  its  species.  Further, 
upon  the  form  follows  an  inclination  to  the  end,  or  to  an 
action,  or  something  of  the  sort ;  for  everything,  in  so  far  as 
it  is  in  act,  acts  and  tends  towards  that  which  is  in  accor- 
dance with  its  form;  and  this  belongs  to  weight  and  order. 
Hence  the  essence  of  goodness,  so  far  as  it  consists  in  perfec- 
tion, consists  also  in  mode,  species,  and  order. 

Reply  Obj.  i.  These  three  only  follow  upon  being,  so  far  as 
it  is  perfect,  and  according  to  this  perfection  is  it  good. 

Reply  Obj.  2.  Mode,  species,  and  order,  are  said  to  be 
good,  and  to  be  beings,  not  as  though  they  themselves  were 
subsistences,  but  because  it  is  through  them  that  other 
things  are  both  beings  and  good.  Hence  they  have  no 
need  of  other  things  whereby  they  are  good:  for  they  are 
spoken  of  as  good,  not  as  though  formally  constituted  so 
by  something  else,  but  as  formally  constituting  others 
good :  thus  whiteness  is  not  said  to  be  a  being  as  though  it 
were  by  anything  else;  but  because,  by  it,  something  else 
has  accidental  being,  as  an  object  that  is  white. 

Reply  Obj.  3.  Every  being  is  due  to  some  form.  Hence, 
according  to  every  being  of  a  thing  is  its  mode,  species, 
order.    Thus,  a  man  has  a  mode,  species,  and  order,  as  a 


Q.  5.  Art.  6    THE  "  SUMMA  THEOLOGICA  "  62 

man;  and  another  mode,  species,  and  order,  as  he  is  white, 
virtuous,  learned,  and  so  on;  according  to  everything 
predicated  of  him.  But  evil  deprives  a  thing  of  some  sort  of 
being,  as  bHndness  deprives  us  of  that  being  which  is  sight ; 
yet  it  does  not  destroy  every  mode,  species,  and  order,  but 
only  such  as  follow  upon  the  being  of  sight. 

Reply  Obj.  4.  Augustine  says  (De  Nat.  Boni  xxiii.). 
Every  mode,  as  mode,  is  good  (and  the  same  can  be  said  of 
species  and  order).  But  an  evil  mode,  species,  and  order  are 
so  called  as  being  less  than  they  ought  to  be,  or  as  not  belonging 
to  that  to  which  they  ought  to  belong.  Therefore  they  are  called 
evil,  because  they  are  out  of  place  and  incongruous. 

Reply  Obj.  5.  The  nature  of  light  is  spoken  of  as  being 
without  number,  weight,  and  measure,  not  absolutely,  but 
in  comparison  with  corporeal  things,  because  the  power  of 
light  extends  to  all  corporeal  things;  inasmuch  as  it  is  an 
active  quality  of  the  first  body  that  causes  change,  i.e.,  the 
heavens. 

Sixth  Article. 

whether  goodness  is  rightly  divided  into  the 
virtuous,"^  the  useful,  and  the  pleasant  ? 

We  proceed  thus  to  the  Sixth  Article : — 

Objection  i.  It  seems  that  goodness  is  not  rightly  divided 
into  the  virtuous,  the  useful,  and  the  pleasant.  For  good- 
ness is  divided  by  the  ten  predicaments,  as  the  Philosopher 
says  (Ethic,  i.).  But  the  virtuous,  the  useful,  and  the 
pleasant  can  be  found  under  one  predicament.  Therefore 
goodness  is  not  rightly  divided  by  them. 

Obj.  2.  Further,  every  division  is  made  by  opposites.  But 
these  three  do  not  seem  to  be  opposites;  for  the  virtuous  is 
pleasing,  and  no  wickedness  is  useful ;  whereas  this  ought  to 
be  the  case  if  the  division  were  made  by  opposites,  for  then 
the  virtuous  and  the  useful  would  be  opposed;  and  Tully 
speaks  of  this  {De  Offic.  ii.).  Therefore  this  division  is 
incorrect. 

■^  Bonum  honestum  is  the  virtuous  good  considered   as   fitting 
Cf.  ii-ii.,  Q.  CXLL,  A.  3:  Q.  CXLV. 


63  GOODNESS  IN  GENERAL         Q.  5.  Art.  6 

Obj.  3.  Further,  where  one  thing  is  on  account  of  another, 
there  is  only  one  thing.  But  the  useful  is  not  goodness, 
except  so  far  as  it  is  pleasing  and  virtuous.  Therefore  the 
useful  ought  not  to  be  divided  against  the  pleasant  and  the 
virtuous. 

On  the  contrary,  Ambrose  makes  use  of  this  division  of 
goodness  {De  Offic.  i.  9). 

/  answer  that,  This  division  properly  concerns  human  good- 
ness. But  if  we  consider  the  nature  of  goodness  from  a 
higher  and  more  universal  point  of  view,  we  shall  find  that 
this  division  properly  concerns  goodness  as  such.  For 
everything  is  good  so  far  as  it  is  desirable,  and  is  a  term  of 
the  movement  of  the  appetite ;  the  term  of  whose  movement 
can  be  seen  from  a  consideration  of  the  movement  of  a 
natural  body.  Now  the  movement  of  a  natural  body  is 
terminated  by  the  end  absolutely;  and  relatively  by  the 
means  through  which  it  comes  to  the  end,  where  the  move- 
ment ceases;  so  a  thing  is  called  a  term  of  the  movement, 
so  far  as  it  terminates  any  part  of  that  movement.  Now 
the  ultimate  term  of  movement  can  be  taken  in  two  ways, 
either  as  the  thing  itself  towards  which  it  tends,  e.g.,  3.  place 
or  form;  or  a  state  of  rest  in  that  thing.  Thus,  in  the 
movement  of  the  appetite,  the  thing  desired  that  terminates 
the  movement  of  the  appetite  relatively,  as  a  means  by 
which  something  tends  towards  another,  is  called  the 
useful;  but  that  sought  after  as  the  last  thing  absolutely 
terminating  the  movement  of  the  appetite,  as  a  thing 
towards  which  for  its  own  sake  the  appetite  tends,  is  called 
the  virtuous;  for  the  virtuous  is  that  which  is  desired  for 
its  own  sake;  but  that  which  terminates  the  movement  of 
the  appetite  in  the  form  of  rest  in  the  thing  desired,  is 
called  the  pleasant. 

Reply  Obj.  1.  Goodness,  so  far  as  it  is  identical  with  being, 
is  divided  by  the  ten  predicaments.  But  this  division 
belongs  to  it  according  to  its  proper  formality. 

Reply  Obj.  2.  This  division  is  not  by  opposite  things; 
but  by  opposite  aspects.  Now  those  things  are  called 
pleasing  which  have  no  other  formality  under  which  they 


Q.  5.  Art.  6    THE  "  SUMMA  THEOLOGICA  "  64 

are  desirable  except  the  pleasant,  being  sometimes  hurtful 
and  contrary  to  virtue.  Whereas  the  useful  apphes  to 
such  as  have  nothing  desirable  in  themselves,  but  are 
desired  only  as  helpful  to  something  further,  as  the  taking 
of  bitter  medicine ;  while  the  virtuous  is  predicated  of  such 
as  are  desirable  in  themselves. 

Reply  Obj.  3.  Goodness  is  not  divided  into  these  three  as 
something  univocal  to  be  predicated  equally  of  them  all; 
but  as  something  analogical  to  be  predicated  of  them 
according  to  priority  and  posteriority.  Hence  it  is  pre- 
dicated chiefly  of  the  virtuous;  then  of  the  pleasant;  and 
lastly  of  the  useful. 


QUESTION  VI. 

THE  GOODNESS  OF  GOD. 
{In  Four  Articles.) 

We  next  consider  the  goodness  of  God;  under  which  head 
there  are  four  points  of  inquiry:  (i)  Whether  goodness 
belongs  to  God  ?  (2)  Whether  God  is  the  supreme  good  ? 
(3)  Whether  He  alone  is  essentially  good  ?  (4)  Whether 
all  things  are  good  by  the  divine  goodness  ? 

First  Article, 
whether  god  is  good  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  to  be  good  does  not  belong  to 
God.  For  goodness  consists  in  mode,  species,  and  order. 
But  these  do  not  seem  to  belong  to  God;  since  God  is  im- 
mense; and  is  not  ordered  to  anything  else.  Therefore  to 
be  good  does  not  belong  to  God. 

Ohj.  2.  Further,  the  good  is  what  all  things  desire.  But 
all  things  do  not  desire  God,  because  all  things  do  not  know 
Him;  and  nothing  is  desired  unless  it  is  known.  Therefore 
to  be  good  does  not  belong  to  God. 

On  the  contrary,  It  is  written  (Lam.  iii.  25) :  The  Lord  is 
good  to  them  that  hope  in  Him,  to  the  soul  that  seeketh  Him, 

I  answer  that,  To  be  good  belongs  pre-eminently  to  God. 
For  a  thing  is  good  according  to  its  desirableness.  Now 
everything  seeks  after  its  own  perfection ;  and  the  perfection 
and  form  of  an  effect  consist  in  a  certain  likeness  to  the 
agent,  since  every  agent  makes  its  like ;  and  hence  the  agent 
itself  is  desirable  and  has  the  nature  of  good.  For  the  very 
thing  which  is  desirable  in  it  is  the  participation  of  its  like- 
I-  65  5 


Q.  6.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  66 

ness.  Therefore,  since  God  is  the  first  effective  cause  of  all 
things,  it  is  manifest  that  the  aspect  of  good  and  of  desirable- 
ness belong  to  Him;  and  hence  Dionysius  {Dii>.  Norn,  iv.) 
attributes  good  to  God  as  to  the  first  efficient  cause, 
saying  that,  God  is  called  good  as  by  Whom  all  things 
subsist. 

Reply  Obj.  i.  To  have  mode,  species,  and  order,  belongs  to 
the  essence  of  caused  good;  but  good  is  in  God  as  in  its 
cause,  and  hence  it  belongs  to  Him  to  impose  mode,  species, 
and  order  on  others;  wherefore  these  three  things  are  in 
God  as  in  their  cause. 

Reply  Obj.  2.  All  things,  by  desiring  their  own  perfection, 
desire  God  Himself,  inasmuch  as  the  perfections  of  all  things 
are  so  many  similitudes  of  the  divine  being ;  as  appears  from 
what  is  said  above  (Q.  IV.,  A.  3).  And  so  of  those  things 
which  desire  God,  some  know  Him  as  He  is  Himself,  and  this 
is  proper  to  the  rational  creature :  others  know  some  partici- 
pation of  His  goodness,  and  this  belongs  also  to  sensible 
knowledge:  others,  have  a  natural  desire  without  know- 
ledge, as  being  directed  to  their  ends  by  a  higher  intelligence. 

Second  Article, 
whether  god  is  the  supreme  good  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  God  is  not  the  supreme  good. 
For  the  supreme  good  adds  something  to  good;  otherwise 
it  would  belong  to  every  good.  But  everything  which  is  an 
addition  to  anything  else  is  a  compound  thing :  therefore  the 
supreme  good  is  compound.  But  God  is  supremely  simple ; 
as  was  shown  above  (Q.  III.,  A.  7).  Therefore  God  is  not  the 
supreme  good. 

Obj.  2.  Further,  Good  is  what  all  desire,  as  the  Philosopher 
says  (Ethic,  i.  i) .  Now  what  all  desire  is  nothing  but  God, 
Who  is  the  end  of  all  things :  therefore  there  is  no  other  good 
but  God.  This  appears  also  from  what  is  said  (Luke  xviii. 
19) :  None  is  good  but  God  alone.  But  we  use  the  word 
supreme  in  comparison  with  others,  as,  e.g.,  supreme  heat 


67  THE  GOODNESS  OF  GOD         Q  6.  Art.  2 

is  used  in  comparison  with  all  other  heats.  Therefore  God 
cannot  be  called  the  supreme  good. 

Obj.  3.  Further,  supreme  implies  comparison.  But  things 
not  in  the  same  genus  are  not  comparable;  as,  sweetness 
is  not  properly  called  greater  or  less  than  a  line.  There- 
fore, since  God  is  not  in  the  same  genus  as  other  good  things, 
as  appears  above  (QQ.  IIL,  A.  5;  IV.,  A.  3)  it  seems  that 
God  cannot  be  called  the  supreme  good  in  relation  to  others. 

On  the  contrary,  Augustine  says  [De  Trin.  ii.)  that,  the 
Trinity  of  the  divine  persons  is  the  supreme  good,  discerned 
by  purified  minds. 

I  answer  that,  God  is  the  supreme  good  simply,  and  not 
only  as  existing  in  any  genus  or  order  of  things.  For  good  is 
attributed  to  God,  as  was  said  in  the  preceding  article,  inas- 
much as  all  desired  perfections  flow  from  Him  as  from  the 
first  cause.  They  do  not,  however,  flow  from  Him  as  from  a 
univocal  agent,  as  shown  above  (Q.  IV.  A.,  2) ;  but  as  from  an 
agent  which  does  not  agree  with  its  effects  either  in  species 
or  genus.  Now  the  likeness  of  an  effect  in  the  univocal 
cause  is  found  uniformly;  but  in  the  equivocal  cause  it  is 
found  more  excellently,  as,  heat  is  in  the  sun  more  excellently 
than  it  is  in  fire.  Therefore  as  good  is  in  God  as  in  the  first, 
but  not  the  univocal,  cause  of  all  things,  it  must  be  in  Him 
in  a  most  excellent  way;  and  therefore  He  is  called  the 
supreme  good. 

Reply  Obj.  i.  The  supreme  good  does  not  add  to  good 
any  absolute  thing,  but  only  a  relation.  Now  a  relation  of 
God  to  creatures,  is  not  a  reality  in  God,  but  in  the  creature; 
for  it  is  in  God  in  our  idea  only :  as,  what  is  knowable  is  so 
called  with  relation  to  knowledge,  not  that  it  depends  on 
knowledge,  but  because  knowledge  depends  on  it.  Thus 
it  is  not  necessary  that  there  should  be  composition  in  the 
supreme  good,  but  only  that  other  things  are  deficient  in 
comparison  with  it. 

Reply  Obj.  2.  When  we  say  that  good  is  what  all  desire, 
it  is  not  to  be  understood  that  every  kind  of  good  thing 
is  desired  by  all  ;  but  that  whatever  is  desired  has  the 
nature  of  good.     And  when  it  is  said,  None  is  good  but  God 


Q.  6.  Art.  3     THE  "  SUMMA  THEOLOGICA  "  68 

alone,  this  is  to  be  understood  of  essential  goodness,  as  will 
be  explained  in  the  next  article. 

Reply  Obj.  3.  Things  not  of  the  same  genus  are  in  no  way 
comparable  to  each  other  if  indeed  they  are  in  different 
genera.  Now  we  say  that  God  is  not  in  the  same  genus  with 
other  good  things;  not  that  He  is  in  any  other  genus,  but 
that  He  is  outside  genus,  and  is  the  principle  of  every  genus; 
and  thus  He  is  compared  to  others  by  excess,  and  it  is  this 
kind  of  comparison  the  supreme  good  implies. 


Third  Article, 
whether  to  be  essentially  good  belongs  to  god 

ALONE  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  to  be  essentially  good  does  not 
belong  to  God  alone.  For  as  one  is  convertible  with  being, 
so  is  good;  as  we  said  above  (Q.  V.,  A.  i).  But  every  being 
is  one  essentially,  as  appears  from  the  Philosopher  (Metaph. 
iv.) ;  therefore  every  being  is  good  essentially. 

Obj,  2.  Further,  if  good  is  what  all  things  desire,  since 
being  itself  is  desired  by  all,  then  the  being  of  each  thing  is 
its  good.  But  everything  is  a  being  essentially:  therefore 
.every  being  is  good  essentially. 

Obj.  3.  Further,  everything  is  good  by  its  own  goodness. 

Therefore  if  there  is  anything  which  is  not  good  essentially 

it  is  necessary  to  say  that  its  goodness  is  not  its  own  essence. 

Therefore  its  goodness,  since  it  is  a  being,  must  be  good; 

and  if  it  is  good  by  some  other  goodness,  the  same  question 

applies  to  that  goodness  also;  therefore  we  must  either 

proceed  to  infinity,  or  come  to  some  goodness  which  is  not 

good  by  any  other  goodness.     Therefore  the  first  supposition 

holds  good.    Therefore  everything  is  good  essentially. 

^^  On  the  contrary,  Boethius   says  (De  Hebdom),   that   all 

i  things  but  God  are  good  by  participation.    Therefore  they 

\  are  not  good  essentially. 

^    I  answer  that,  God  alone  is  good  essentially.     For  every- 
thing is  called  good  according  to  its  perfection.    Now  per- 


69  THE  GOODNESS  OF  GOD         Q.  6.  Art.  3 

f ection  of  a  thing  is  threefold :  first,  according  to  the  consti- 
tution of  its  own  being ;  secondly,  in  respect  of  any  accidents 
being  added  as  necessary  for  its  perfect  operation;  thirdly, 
perfection  consists  in  the  attaining  to  something  else  as  the 
end.  Thus,  for  instance,  the  first  perfection  of  fire  consists 
in  its  existence,  which  it  has  through  its  own  substantial 
form;  its  secondary  perfection  consists  in  heat,  lightness 
and  dryness,  and  the  like;  its  third  perfection  is  to  rest 
in  its  own  place.  This  triple  perfection  belongs  to  no 
creature  by  its  own  essence;  it  belongs  to  God  only,  in 
Whom  alone  essence  is  existence;  in  Whom  there  are  no 
accidents;  since  whatever  belongs  to  others  accidentally 
belongs  to  Him  essentially;  as,  to  be  powerful,  wise,  and 
the  like,  as  appears  from  what  is  stated  above  (Q.  HL,  A.  6) ; 
and  He  is  not  directed  to  anything  else  as  to  an  end,  but 
is  Himself  the  last  end  of  all  things.  Hence  it  is  manifest 
that  God  alone  has  every  kind  of  perfection  by  His  own 
essence ;  therefore  He  Himself  alone  is  good  essentially. 

Reply  Ohj.  i.  One  does  not  include  the  idea  of  perfection, 
but  only  of  indivision,  which  belongs  to  everything  according 
to  its  own  essence.  Now  the  essences  of  simple  things  are 
undivided  both  actually  and  potentially,  but  the  essences 
of  compound  things  are  undivided  only  actually;  and 
therefore  everything  must  be  one  essentially,  but  not  good 
essentially,  as  was  shown  above. 

Reply  Ohj.  2.  Although  everything  is  good  in  that  it  has 
being,  yet  the  essence  of  a  creature  is  not  very  being* 
and  therefore  it  does  not  follow  that  a  creature  is  good 
essentially. 

Reply  Ohj.  3.  The  goodness  of  a  creature  is  not  its  very 
essence,  but  something  superadded ;  it  is  either  its  existence, 
or  some  added  perfection,  or  the  order  to  its  end.  Still, 
the  goodness  itself  thus  added  is  good,  just  as  it  is  being. 
But  for  this  reason  is  it  called  being  because  by  it  something 
has  being,  not  because  it  itself  has  being  through  something 
else:  hence  for  this  reason  is  it  called  good  because  by  it 
something  is  good,  and  not  because  it  itself  has  some  other 
goodness  whereby  it  is  good. 


Q.  6.  Art.  4    THE  ''  SUMMA  THEOLOGICA  "  70 

Fourth  Article, 
whether  all  things  are  good  by  the  divine  goodness  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  all  things  are  good  by  the 
divine  goodness.  For  Augustine  says  {De  Trin.  viii.),  This 
and  that  are  good ;  take  away  this  and  that,  and  see  good  itself 
if  thou  canst ;  and  so  thou  shalt  see  God,  good  not  by  any  other 
good,  but  the  good  of  every  good.  But  everything  is  good  by 
its  own  good:  therefore  everything  is  good  by  that  very 
good  which  is  God. 

Obj.  2.  Further,  as  Boethius  says  (De  Hebdom.),  all  things 
are  called  good,  accordingly  as  they  are  directed  to  God, 
and  this  is  by  reason  of  the  divine  goodness:  therefore  all 
things  are  good  by  the  divine  goodness. 

On  the  contrary,  All  things  are  good,  inasmuch  as  they 
have  being.  But  they  are  not  called  beings  through  the 
divine  being,  but  through  their  own  being:  therefore  all 
things  are  not  good  by  the  divine  goodness,  but  by  their 
own  goodness. 

/  answer  that.  As  regards  relative  things,  we  may  admit 
extrinsic  denomination;  as,  a  thing  is  denominated  placed 
from  place,  and  measured  from  measure.  But  as  regards 
absolute  things  opinions  differ.  Plato  held  the  existence 
of  separate  ideas  (Q.  LXXXIV.,  A.  4)  of  all  things,  and  that 
individuals  were  denominated  by  them  as  participating  in  the 
separate  ideas;  for  instance,  that  Socrates  is  called  man 
according  to  the  separate  idea  of  man.  Now  just  as  he  laid 
down  separate  ideas  of  man  and  horse  which  he  called  absolute 
man  and  absolute  horse;  so  likewise  he  laid  down  separate 
ideas  of  being  and  of  one,  and  these  he  called  absolute  being 
and  absolute  oneness ;  and  by  participation  of  these  everything 
was  called  being  or  one  ;  and  what  was  thus  absolute  being 
and  absolute  one,  he  said  was  the  supreme  good.  And 
because  good  is  convertible  with  being,  as  one  is  also;  he 
called  God  the  absolute  good,  from  whom  all  things  are 
called  good  by  way  of  participation. 


71  THE  GOODNESS  OF  GOD        Q.  6.  Art.  4 

Although  this  opinion  appears  to  be  unreasonable  in 
affirming  separate  ideas  of  natural  things  as  subsisting  of 
themselves — -as  Aristotle  argues  in  many  ways — still,  it  is 
absolutely  true  that  there  is  first  something  which  is  essen- 
tially being  and  essentially  good,  which  we  call  God,  as 
appears  from  what  is  shown  above  (Q.  II.,  A.  3),  and 
Aristotle  agrees  with  this.  Hence  from  the  first  being, 
essentially  such,  and  good,  everything  can  be  called  good 
and  a  being,  inasmuch  as  it  participates  in  it  by  way  of  a 
certain  assimilation  which  is  far  removed  and  defective; 
as  appears  from  the  above  (Q.  IV.,  A.  3). 

Everything  is  therefore  called  good  from  the  divine  good- 
ness, as  from  the  first  exemplary  effective  and  final  principle 
of  all  goodness.  Nevertheless,  everything  is  called  good  by 
reason  of  the  similitude  of  the  divine  goodness  belonging 
to  it,  which  is  formally  its  own  goodness,  whereby  it  is 
denominated  good.  And  so  of  aU  things  there  is  one  good- 
ness, and  yet  many  goodnesses. 

This  is  a  sufficient  Reply  to  the  Objections. 


QUESTION  VII. 

THE  INFINITY  OF  GOD. 

{In  Four  Articles.) 

After  considering  the  divine  perfection  we  must  consider 
the  divine  infinity,  and  God's  existence  in  things:  for  God  is 
everywhere,  and  in  all  things,  inasmuch  as  He  is  boundless 
and  infinite. 

Concerning  the  first,  there  are  four  points  of  inquiry: 
(i)  Whether  God  is  infinite  ?  (2)  Whether  anything  besides 
Him  is  infinite  in  essence  ?  (3)  Whether  anything  can  be 
infinite  in  magnitude  ?  (4)  Whether  an  infinite  multitude 
can  exist  ? 

First  Article, 
whether  god  is  infinite  ? 

We  proceed  thus  to  the  First  Article : — 

Objection  i.  It  seems  that  God  is  not  infinite.  .For  every- 
thing infinite  is  imperfect,  as  the  Philosopher  says;  because 
it  has  parts  and  matter,  as  is  said  in  Physic,  iii.  But  God 
is  most  perfect :  therefore  He  is  not  infinite. 

Ohj.  2.  Further,  according  to  the  Philosopher  {Physic,  i.), 
finite  and  infinite  belong  to  quantity.  But  there  is  no 
quantity  in  God,  for  He  is  not  a  body,  as  was  shown  above 
(Q.  III.,  A.  i).  Therefore  it  does  not  belong  to  Him  to 
be  infinite. 

Ohj.  3.  Further,  what  is  here  in  such  a  way  as  not  to  be 
elsewhere,  is  finite  according  to  place.  Therefore  that 
which  is  a  thing  in  such  a  way  as  not  to  be  another  thing, 
is  finite  according  to  substance.  But  God  is  this,  and  not 
another;  for  He  is  not  a  stone  or  wood.  Therefore  God  is 
not  infinite  in  substance. 

72 


73  THE  INFINITY  OF  GOD  Q.  7.  Art.  1 

On  the  contrary y  Damascene  says  {De  Fide  Orth.=i.  4)  that, 
God  is  infinite  and  eternal y  and  boundless. 

I  answer  that,  All  the  ancient  philosophers  attribute  in- 
finitude to  the  first  principle,  as  is  said  (Physic,  iii.),  and  with 
reason ;  for  they  considered  that  things  flow  forth  infinitely 
from  the  first  principle.  But  because  some  erred  concern- 
ing the  nature  of  the  first  principle,  as  a  consequence  they 
erred  also  concerning  its  infinity ;  forasmuch  as  they  asserted 
that  matter  was  the  first  principle;  consequently  they 
attributed  to  the  first  principle  a  material  infinity,  to  the 
effect  that  some  infinite  body  was  the  first  principle  of 
things. 

We  must  consider  therefore  that  a  thing  is  called  infinite 
because  it  is  not  finite.  Now  matter  is  in  a  way  made  finite 
by  form,  and  the  form  by  matter.  Matter  indeed  is  made 
finite  by  form,  inasmuch  as  matter,  before  it  receives  its 
form,  is  in  potentiality  to  many  forms;  but  on  receiving 
a  form,  it  is  terminated  by  that  one.  Again,  form  is  made 
finite  by  matter,  inasmuch  as  form,  considered  in  itself, 
is  common  to  many;  but  when  received  in  matter,  the  form 
is  determined  to  this  one  particular  thing.  Now  matter 
is  perfected  by  the  form  by  which  it  is  made  finite ;  therefore 
infinite  as  attributed  to  matter,  has  the  nature  of  something 
imperfect ;  for  it  is  as  it  were  formless  matter.  On  the  other 
hand  form  is  not  made  perfect  by  matter,  but  rather  is 
contracted  by  matter;  and  hence  the  infinite,  regarded  on 
the  part  of  the  form  not  determined  by  matter,  has  the 
nature  of  something  perfect.  Now  being  is  the  most  formal 
of  all  things,  as  appears  from  what  is  shown  above  (Q.  IV., 
A.  I,  Obj.  3).  Since  therefore  the  divine  being  is  not  a  being 
received  in  anything,  but  He  is  His  own  subsistent  being  as 
was  shown  above  (Q.  III.,  A.  4),  it  is  clear  that  God  Himself 
is  infinite  and  perfect. 

From  this  appears  the  Reply  to  the  First  Objection. 

Reply  Obj.  2.  Quantity  is  terminated  by  its  form,  which 
can  be  seen  in  the  fact  that  a  figure  which  consists  in  quantity 
terminated,  is  a  kind  of  quantitative  form.  Hence  the 
infinite  of  quantity  is  the  infinite  of  matter;  such  a  kind  of 


Q.  7.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  74 

infinite  cannot  be  attributed  to  God;  as  was  said  above, 
in  this  article. 

Reply  Ohj.  3.  The  fact  that  the  being  of  God  is  self-sub- 
sisting, not  received  in  any  other,  and  is  thus  called  infinite, 
shows  Him  to  be  distinguished  from  all  other  beings,  and 
all  others  to  be  apart  from  Him.  Even  so,  were  there  such 
a  thing  as  a  self-subsisting  whiteness,  the  very  fact  that  it 
did  not  exist  in  an5^hing  else,  would  make  it  distinct  from 
every  other  whiteness  existing  in  a  subject. 


Second  Article, 
whether  anything  but  god  can  be  essentially  infinite? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  something  else  besides  God  can 
be  essentially  infinite.  For  the  power  of  anything  is  propor- 
tioned to  its  essence.  Now  if  the  essence  of  God  is  infinite, 
His  power  must  also  be  infinite.  Therefore  He  can  produce 
an  infinite  effect,  since  the  extent  of  a  power  is  known  by 
its  effect. 

Ohj,  2.  Further,  whatever  has  infinite  power,  has  an 
infinite  essence.  Now  the  created  intellect  has  an  infinite 
power;  for  it  apprehends  the  universal,  which  can  extend 
itself  to  an  infinitude  of  singular  things.  Therefore  every 
created  intellectual  substance  is  infinite. 

Ohj.  3.  Further,  primary  matter  is  something  other  than 
God,  as  was  shown  above  (Q.  III.,  A.  8).  But  primary 
matter  is  infinite.  Therefore  something  besides  God  can  be 
infinite. 

On  the  contrary,  The  infinite  cannot  have  a  beginning,  as 
said  in  Physic,  iii.  But  everything  outside  God  is  from 
God  as  from  its  first  principle.  Therefore  besides  God 
nothing  can  be  infinite. 

/  answer  that,  Things  other  than  God  can  be  relatively  in- 
finite, but  not  absolutely  infinite.  For  with  regard  to  infinite 
as  applied  to  matter,  it  is  manifest  that  everything  actually 
existing  possesses  a  form ;  and  thus  its  matter  is  determined 
by  form.     But  because  matter,  considered  as  existing  under 


n  THE  INFINITY  OF  GOD  Q.  7.  Art  2 

some  substantial  form,  remains  in  potentiality  to  many 
accidental  forms,  what  is  absolutely  finite  can  be  relatively 
infinite;  as,  for  example,  wood  is  finite  according  to  its  own 
form,  but  still  it  is  relatively  infinite,  inasmuch  as  it  is  in 
potentiality  to  an  infinite  number  of  shapes.  But  if  we 
speak  of  the  infinite  in  reference  to  form,  it  is  manifest 
that  those  things,  the  forms  of  which  are  in  matter,  are 
absolutely  finite,  and  in  no  way  infinite.  If  however  any 
created  forms  are  not  received  into  matter,  but  are  self- 
subsisting,  as  some  think  is  the  case  with  the  angels,  these 
will  be  relatively  infinite,  inasmuch  as  such  kinds  of  forms 
are  not  terminated,  nor  contracted  by  any  matter.  But 
because  a  created  form  thus  subsisting  has  being,  and  yet 
is  not  its  own  being,  it  follows  that  its  being  is  received 
and  contracted  to  a  determinate  nature.  Hence  it  cannot 
be  absolutely  infinite. 

Reply  Obj.  i.  It  is  against  the  nature  of  a  made  thing 
for  its  essence  to  be  its  existence;  because  subsisting  being 
is  not  a  created  being;  hence  it  is  against  the  nature  of  a 
made  thing  to  be  absolutely  infinite.  Therefore,  as  God, 
although  He  has  infinite  power,  cannot  make  a  thing  to 
be  not  made  (for  this  would  imply  that  two  contradictories 
are  true  at  the  same  time),  so  likewise  He  cannot  make 
anything  to  be  absolutely  infinite. 

Reply  Obj.  2.  The  fact  that  the  power  of  the  intellect 
extends  itself  in  a  way  to  infinite  things,  is  because  the 
intellect  is  a  form  not  in  matter,  but  either  wholly  sepajjfed 
from  matter,  as  is  the  angelic  substance,  or  at  le3.Wrkn 
intellectual  power,  which  is  not  the  act  of  any  organ,  in 
the  intellectual  soul  joined  to  a  body. 

Reply  Obj.  3.  Primary  matter  does  not  exist  by  itself  in 
nature,  since  it  is  not  actually  being,  but  potentially  only; 
hence  it  is  something  concreated  rather  than  created. 
Nevertheless,  primary  matter  even  as  a  potentiality  is  not 
absolutely  infinite,  but  relatively,  because  its  potentiality 
extends  onlv  to  natural  forms.

Third  Article, 
whether  an  actually  infinite  magnitude  can  exist  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  there  can  be  something  actually 
infinite  in  magnitude.  For  in  mathematics  there  is  no  error, 
since  there  is  no  lie  in  things  abstract,  as  the  Philosopher  says 
{Physic,  ii.).  But  mathematics  use  the  infinite  in  magnitude ; 
thus,  the  geometrician  in  his  demonstrations  says.  Let  this 
line  be  infinite.  Therefore  it  is  not  impossible  for  a  thing 
to  be  infinite  in  magnitude. 

Obj.  2.  Further,  what  is  not  against  the  nature  of  any- 
thing, can  agree  with  it.  Now  to  be  infinite  is  not  against 
the  nature  of  magnitude;  but  rather  both  the  finite  and  the 
infinite  seem  to  be  properties  of  quantity.  Therefore  it  is 
not  impossible  for  some  magnitude  to  be  infinite. 

Obj.  3.  Further,  magnitude  is  infinitely  divisible,  for  the 
continuous  is  defined  that  which  is  infinitely  divisible,  as  is 
clear  from  Physic,  iii.  But  contraries  are  concerned  about 
one  and  the  same  thing.  Since  therefore  addition  is  opposed 
to  division,  and  increase  is  opposed  to  diminution,  it  appears 
that  magnitude  can  be  increased  to  infinity.  Therefore 
it  is  possible  for  magnitude  to  be  infinite. 

Obj.  4.  Further,  movement  and  time  have  quantity  and 
continuity  derived  from  the  magnitude  over  which  move- 
ment passes,  as  is  said  in  Physic,  iv.  But  it  is  not  against 
the  nature  of  time  and  movement  to  be  infinite,  since  every 
determinate  indivisible  in  time  and  circular  movement  is 
both  a  beginning  and  an  end.  Therefore  neither  is  it  against 
the  nature  of  magnitude  to  be  infinite. 

On  the  contrary.  Every  body  has  a  surface.  But  every 
body  which  has  a  surface  is  finite ;  because  surface  is  the  term 
of  a  finite  body.  Tlierefore  all  bodies  are  finite.  The  same 
applies  both  to  surface  and  to  a  line.  Therefore  nothing  is 
infinite  in  magnitude. 

I  answer  that,  It  is  one  thing  to  be  infinite  in  essence,  and 
another  to  be  infinite  in  magnitude.     For  granted  that  a 


^^  THE  INFINITY  OF  GOD  Q.  7.  Art.  3 

body  exists  infinite  in  magnitude,  as  fire  or  air,  yet  this 
could  not  be  infinite  in  essence,  because  its  essence  would  be 
terminated  in  a  species  by  its  form,  and  confined  to  individu- 
ality by  matter.  And  so  assuming  from  these  premisses 
that  no  creature  is  infinite  in  essence,  it  still  remains  to 
inquire  whether  any  creature  can  be  infinite  in  magnitude. 

We  must  therefore  observe  that  a  body,  which  is  a  tom- 
plete  magnitude,  can  be  considered  in  two  ways;  mathe- 
matically, in  respect  to  its  quantity  only;  and  naturally, 
as  regards  its  matter  and  form. 

Now  it  is  manifest  that  a  natural  body  cannot  be  actually 
infinite.  For  every  natural  body  has  some  determined 
substantial  form.  Since  therefore  the  accidents  follow  upon 
the  substantial  form,  it  is  necessary  that  determinate 
accidents  should  follow  upon  a  determinate  form;  and 
among  these  accidents  is  quantity.  So  every  natural  body 
has  a  greater  or  smaller  determinate  quantity.  Hence  it  is 
impossible  for  a  natural  body  to  be  infinite.  The  same 
appears  from  movement;  because  every  natural  body  has 
some  natural  movement ;  whereas  an  infinite  body  could  not 
have  any  natural  movement ;  neither  direct,  because  nothing 
moves  naturally  by  a  direct  movement  unless  it  is  out  of  its 
place;  and  this  could  not  happen  to  an  infinite  body,  for  it 
would  occupy  every  place,  and  thus  every  place  would  be 
indifferently  its  own  place.  Neither  could  it  move  circularly ; 
forasmuch  as  circular  motion  requires  that  one  part  of  the 
body  is  necessarily  transferred  to  a  place  occupied  by 
another  part,  and  this  could  not  happen  as  regards  an  infinite 
circular  body :  for  if  two  lines  be  drawn  from  the  centre,  the 
farther  they  extend  from  the  centre,  the  farther  they  are 
from  each  other;  therefore,  if  a  body  were  infinite,  the 
lines  would  be  infinitely  distant  from  each  other;  and 
thus  one  could  never  occupy  the  place  belonging  to  any 
other. 

The  same  applies  to  a  mathematical  body.  For  if  we 
imagine  a  mathematical  body  actually  existing,  we  must 
imagine  it  under  some  form,  because  nothing  is  actual  except 
by  its  form;  hence,  since  the  form  of  quantity  as  such  is 


Q.  7.  Art.  4    THE  ''  SUMMA  THEOLOGICA  "  78 

figure,  such  a  body  must  have  some  figure,  and  so  would  be 
finite;  for  figure  is  confined  by  a  term  or  boundary. 

Reply  Obj.  1.  A  geometrician  does  not  need  to  assume 
a  line  actually  infinite,  but  takes  some  actually  finite  line, 
from  which  he  subtracts  whatever  he  finds  necessary ;  which 
line  he  calls  infinite. 

Reply  Obj.  2.  Although  the  infinite  is  not  against  the 
nature  of  magnitude  in  general,  still  it  is  against  the  nature 
of  any  species  of  it ;  thus,  for  instance,  it  is  against  the  nature 
of  a  bicubical  or  tricubical  magnitude,  whether  circular  or 
triangular,  and  so  on.  Now  what  is  not  possible  in  any 
species  cannot  exist  in  the  genus ;  hence  there  cannot  be  any 
infinite  magnitude,  since  no  species  of  magnitude  is  infinite. 

Reply  Obj.  3.  The  infinite  in  quantity,  as  was  shown 
above,  belongs  to  matter.  Now  by  division  of  the  whole  we 
approach  to  matter,  forasmuch  as  parts  have  the  aspect  of 
matter;  but  by  addition  we  approach  to  the  whole  which 
has  the  aspect  of  a  form.  Therefore  the  infinite  is  not  in 
the  addition  of  magnitude,  but  only  in  division. 

Reply  Obj.  4.  Movement  and  time  are  whole,  not  actually 
but  successively;  hence  they  have  potentiality  mixed  with 
actuality.  But  magnitude  is  an  actual  whole;  therefore  the 
infinite  in  quantity  refers  to  matter,  and  does  not  agree  with 
the  totality  of  magnitude;  yet  it  agrees  with  the  totality  of 
time  or  movement:  for  it  is  proper  to  matter  to  be  in 
potentiality. 

Fourth  Article, 
whether  an  infinite  multitude  can  exist  ? 

We  proceed  thus  to  the  Fourth  Article  : — • 

Objection  i.  It  seems  that  an  actually  infinite  multitude  is 
possible.  For  it  is  not  impossible  for  a  potentiality  to  be 
made  actual.  But  number  can  be  multiplied  to  infinity. 
Therefore  it  is  possible  for  an  infinite  multitude  actually  to 
exist. 

Obj.  2.  Further,  it  is  possible  for  any  individual  of  any 
species  to  be  made  actual.     But  the  species  of  figures  are 


79  THE  INFINITY  OF  GOD  Q.  7.  Art.  4 

infinite.  Therefore  an  infinite  number  of  actual  figures  is 
possible. 

Obj.  3.  Further,  things  not  opposed  to  each  other  do  not 
obstruct  each  other.  But  supposing  a  multitude  of  things 
to  exist,  there  can  still  be  many  others  not  opposed  to  them. 
Therefore  it  is  not  impossible  for  others  also  to  coexist  with 
them,  and  so  on  to  infinitude;  therefore  an  actual  infinite 
number  of  things  is  possible. 

On  the  contrary,  It  is  written.  Thou  hast  ordered  all  things 
in  measure,  and  number,  and  weight  (Wis.  xi.  21). 

/  answer  that,  A  twofold  opinion  exists  on  this  subject. 
Some,  as  Avicenna  and  Algazel,  said  that  it  was  impossible 
for  an  actually  infinite  multitude  to  exist  absolutely;  but 
that  an  accidentally  infinite  multitude  was  not  impossible. 
A  multitude  is  said  to  be  infinite  absolutely,  when  an  infinite 
multitude  is  necessary  that  something  may  exist.  Now  this 
is  impossible;  because  it  would  entail  something  dependent 
on  an  infinity  for  its  existence;  and  hence  its  generation 
could  never  come  to  be,  because  it  is  impossible  to  pass 
through  an  infinite  medium. 

A  multitude  is  said  to  be  accidentally  infinite  when  its 
existence  as  such  is  not  necessary,  but  accidental.  This  can 
be  shown,  for  example,  in  the  work  of  a  carpenter  requiring 
a  certain  absolute  multitude;  namely,  art  in  the  soul, 
the  movement  of  the  hand,  and  a  hammer;  and  supposing 
that  such  things  were  infinitely  multiplied,  the  carpentering 
work  would  never  be  finished,  forasmuch  as  it  would  depend 
on  an  infinite  number  of  causes.  But  the  multitude  of 
hammers,  inasmuch  as  one  may  be  broken  and  another  used, 
is  an  accidental  multitude;  for  it  happens  by  accident  that 
many  hammers  are  used,  and  it  matters  little  whether  one 
or  two,  or  many  are  used,  or  an  infinite  number,  if  the  work 
is  carried  on  for  an  infinite  time.  In  this  way  they  said  that 
there  can  be  an  accidentally  infinite  multitude. 

This,  however,  is  impossible;  since  every  kind  of  multi- 
tude must  belong  to  a  species  of  multitude.  Now  the  species 
of  multitude  are  to  be  reckoned  by  the  species  of  numbers. 
But  no  species  of  number  is  infinite;  for  every  number  is 


Q.  7.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  80 

multitude  measured  by  one.  Hence  it  is  impossible  for 
there  to  be  an  actually  infinite  multitude,  either  absolute  or 
accidental.  Likewise  multitude  in  nature  is  created;  and 
ever3d:hing  created  is  comprehended  under  some  clear  in- 
tention of  the  Creator;  for  no  agent  acts  aimlessly.  Hence 
everything  created  must  be  comprehended  in  a  certain 
number.  Therefore  it  is  impossible  for  an  actually  infinite 
multitude  to  exist,  even  accidentally.  But  a  potentially 
infinite  multitude  is  possible;  because  the  increase  of  multi- 
tude follows  upon  the  division  of  magnitude;  since  the 
more  a  thing  is  divided,  the  greater  number  of  things  result. 
Hence,  as  the  infinite  is  to  be  found  potentially  in  the 
division  of  the  continuous,  because  we  thus  approach 
matter,  as  was  shown  in  the  preceding  article,  by  the  same 
rule,  the  infinite  can  be  also  found  potentially  in  the  addition 
of  multitude. 

Reply  Obj.  1.  Every  potentiality  is  made  actual  according 
to  its  mode  of  being;  for  instance,  a  day  is  reduced  to  act 
successively,  and  not  all  at  once.  Likewise  the  infinite  in 
multitude  is  reduced  to  act  successively,  and  not  all  at  once ; 
because  every  multitude  can  be  succeeded  by  another  multi- 
tude to  infinity. 

Reply  Obj.  2.  Species  of  figures  are  infinite  by  infinitude 
of  number.  Now  there  are  various  species  of  figures,  such 
as  trilateral,  quadrilateral  and  so  on;  and  as  an  infinitely 
numerable  multitude  is  not  all  at  once  reduced  to  act,  so 
neither  is  the  multitude  of  figures. 

Reply  Obj.  3.  Although  the  supposition  of  some  things 
does  not  preclude  the  supposition  of  others,  still  the  suppo- 
sition of  an  infinite  number  is  opposed  to  any  single  species  of 
multitude.  Hence  it  is  not  possible  for  an  actually  infinite 
multitude  to  exist. 


QUESTION  VIII. 

THE  EXISTENCE  OF  GOD  IN  THINGS. 

{In  Four  Articles.) 

Since  it  evidently  belongs  to  the  infinite  to  be  present 
everywhere,  and  in  all  things,  we  now  consider  whether  this 
belongs  to  God;  and  concerning  this  there  arise  four  points 
of  inquiry:  (i)  Whether  God  is  in  all  things  ?  (2)  Whether 
God  is  everywhere  ?  (3)  Whether  God  is  everywhere  by 
essence,  power,  and  presence  ?  (4)  Whether  to  be  every- 
where belongs  to  God  alone  ? 

First  Article, 
whether  god  is  in  all  things  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  God  is  not  in  all  things.  For 
what  is  above  all  things  is  not  in  all  things.  But  God  is 
above  all,  according  to  the  Psalm  (cxii.  4),  The  Lord  is  high 
above  all  nations,  etc.     Therefore  God  is  not  in  aU  things. 

Obj.  2.  Further,  what  is  in  anything  is  thereby  contained. 
Now  God  is  not  contained  by  things,  but  rather  does  He 
contain  them.  Therefore  God  is  not  in  things;  but  things 
are  rather  in  Him.  Hence  Augustine  says  {Octog.  Tri.  QucBst. 
qti.  20),  that  in  Him  things  are,  rather  than  He  is  in  any 
place. 

Obj.  3.  Further,  the  more  powerful  an  agent  is,  the 
more  extended  is  its  action.  But  God  is  the  most  powerful 
of  all  agents.  Therefore  His  action  can  extend  to  things 
which  are  far  removed  from  Him;  nor  is  it  necessary  that 
He  should  be  in  all  things. 

i>  81  6 


Q.  8.  Art.  i    THE  *'  SUMMA  THEOLOGICA  "  82 

Obj.  4.  Further,  the  demons  are  beings.  But  God  is  not 
in  the  demons;  for  there  is  no  fellowship  between  light 
and  darkness  (2  Cor.  vi.  14).  Therefore  God  is  not  in  all 
things. 

On  the  contrary,  A  thing  is  wherever  it  operates.  But 
God  operates  in  all  things,  according  to  Isa.  xxvi.  12,  Lord  .  . . 
Thou  hast  wrought  all  our  works  in  [Vulg.,/or]  us.  Therefore 
God  is  in  all  things. 

/  answer  that,  God  is  in  all  things;  not,  indeed,  as  part  of 
their  essence,  nor  as  an  accident ;  but  as  an  agent  is  present 
to  that  upon  which  it  works.  For  an  agent  must  be  joined 
to  that  wherein  it  acts  immediately,  and  touch  it  by  its 
power;  hence  it  is  proved  in  Physic,  vii.  that  the  thing 
moved  and  the  mover  must  be  joined  together.  Now  since 
God  is  very  being  by  His  own  Qssence,  created  being  must 
be  His  proper  effect ;  as  to  ignite  is  the  proper  effect  of  fire. 
Now  God  causes  this  effect  in  things  not  only  when  they  first 
begin  to  be,  but  as  long  as  they  are  preserved  in  being;  as 
light  is  caused  in  the  air  by  the  sun  as  long  as  the  air  remains 
illuminated.  Therefore  as  long  as  a  thing  has  being,  God 
must  be  present  to  it,  according  to  its  mode  of  being.  But 
being  is  innermost  in  each  thing  and  most  fundamentally 
inherent  in  all  things  since  it  is  formal  in  respect  of  every- 
thing found  in  a  thing,  as  was  shown  above  (Q.  VH.,  A.  i). 
Hence  it  must  be  that  God  is  in  all  things,  and  innermostly. 

Reply  Obj.  i.  God  is  above  all  things  by  the  excellence 
of  His  nature;  nevertheless.  He  is  in  all  things  as  the  cause 
of  the  being  of  all  things ;  as  was  shown  above  in  this  article. 

Reply  Obj.  2.  Although  corporeal  things  are  said  to  be 
in  another  as  in  that  which  contains  them,  nevertheless 
spiritual  things  contain  those  things  in  which  they  are;  as 
the  soul  contains  the  body.  Hence  also  God  is  in  things  as 
containing  them:  nevertheless  by  a  certain  similitude  to 
corporeal  things,  it  is  said  that  all  things  are  in  God;  inas- 
much as  they  are  contained  by  Him. 

Reply  Obj.  3.  No  action  of  an  agent,  however  powerful 
it  may  be,  acts  at  a  distance,  except  through  a  medium. 
But  it  belongs  to  the  great  power  of  God  that  He  acts 


83  EXISTENCE  OF  GOD  IN  THINGS     Q.  8.  Art.  2 

immediately  in  all  things.  Hence  nothing  is  distant  from 
Him,  as  if  it  could  be  without  God  in  itself.  But  things  are 
said  to  be  distant  from  God  by  the  unlikeness  to  Him  in 
nature  or  grace;  as  also  He  is  above  all  by  the  excellence 
of  His  own  nature. 

Reply  Ohj.  4.  In  the  demons  there  is  their  nature  which 
is  from  God,  and  also  the  deformity  of  sin  which  is  not 
from  Him;  therefore,  it  is  not  to  be  absolutely  conceded 
that  God  is  in  the  demons,  except  with  the  addition,  inas- 
much as  they  are  beings.  But  in  things  not  deformed  in  their 
nature,  we  must  say  absolutely  that  God  is. 

Second  Article, 
whether  god  is  everywhere  ? 

We  proceed  thus  to  the  Second  Article  ; — 

Objection  i.  It  seems  that  God  is  not  everywhere.  For 
to  be  everywhere  means  to  be  in  every  place.  But  to  be  in 
every  place  does  not  belong  to  God,  to  Whom  it  does  not 
belong  to  be  in  place  at  all ;  for  incorporeal  things,  as  Boethius 
says  {De  Hebdom.),  are  not  in  a  place.  Therefore  God  is  not 
everywhere. 

Obj.  2.  Further,  the  relation  of  time  to  succession  is  the 
same  as  the  relation  of  place  to  permanence.  But  one  in- 
divisible part  of  action  or  movement  cannot  exist  in  different 
times ;  therefore  neither  can  one  indivisible  part  in  the  genus 
of  permanent  things  be  in  every  place.  Now  the  divine 
being  is  not  successive,  but  permanent.  Therefore  God  is 
not  in  many  places;  and  thus  He  is  not  everywhere. 

Obj.  3.  Further,  what  is  wholly  in  any  one  place  is  not 
in  part  elsewhere.  But  if  God  is  in  any  one  place  He  is  all 
there;  for  He  has  no  parts.  No  part  of  Him  then  is  else- 
where; and  therefore  God  is  not  everywhere. 

On  the  contrary,  It  is  written,  /  fill  heaven  and  earth  (Jer. 
xxiii.  24). 

/  answer  that.  Since  place  is  a  thing,  to  be  in  place  can 
be  understood  in  a  twofold  sense;  either  by  way  of  other 
things — i.e.,    as  one  thing    is   said    to    be    in    another   no 


Q.  8.  Art.  2.    THE  "  SUMMA  THEOLOGICA  "  84 

matter  how  ;  and  thus  the  accidents  of  a  place  are  in  place ; 
or  by  a  way  proper  to  place ;  and  thus  things  placed  are  in 
place.  Now  in  both  these  senses  in  some  way  God  is  in 
every  place;  and  this  is  to  be  everywhere.  First,  as  He 
is  in  all  things  as  giving  them  being,  power,  and  opera- 
tion; so  He  is  in  every  place  as  giving  it  existence  and 
locative  power.  Again,  things  placed  are  in  place,  inas- 
much as  they  fill  place;  and  God  fills  every  place;  not, 
indeed,  like  a  body,  for  a  body  is  said  to  fill  place  inasmuch 
as  it  excludes  the  co-presence  of  another  body;  whereas  by 
God  being  in  a  place,  others  are  not  thereby  excluded  from 
it ;  indeed,  by  the  very  fact  that  He  gives  being  to  the  things 
that  fill  every  place.     He  Himself  fills  every  place. 

Reply  Ohj.  i.  Incorporeal  things  are  in  place  not  by 
contact  of  dimensive  quantity,  as  bodies  are,  but  by  contact 
of  power. 

Reply  Ohj.  2.  The  indivisible  is  twofold.  One  is  the 
term  of  the  continuous ;  as  a  point  in  permanent  things,  and 
as  a  moment  in  succession;  and  this  kind  of  the  indivisible 
in  permanent  things,  forasmuch  as  it  has  a  determinate 
site,  cannot  be  in  many  parts  of  place,  or  in  many  places; 
likewise  the  indivisible  of  action  or  movement,  forasmuch 
as  it  has  a  determinate  order  in  movement  or  action, 
cannot  be  in  many  parts  of  time.  Another  kind  of  the 
indivisible  is  outside  of  the  whole  genus  of  the  continuous; 
and  in  this  way  incorporeal  substances,  like  God,  angel,  and 
soul,  are  called  indivisible.  Such  a  kind  of  indivisible  does 
not  belong  to  the  continuous,  as  a  part  of  it,  but  as  touching 
it  by  its  power;  hence,  according  as  its  power  can  extend 
itself  to  one  or  to  many,  to  a  small  thing,  or  to  a  great  one, 
in  this  way  it  is  in  one  or  in  many  places,  and  in  a  small  or 
large  place. 

Reply  Ohj.  3.  A  whole  is  so  called  with  reference  to  its 
parts.  Now  part  is  twofold:  viz.,  a  part  of  the  essence,  as 
the  form  and  the  matter  are  called  parts  of  the  composite, 
while  genus  and  difference  are  called  parts  of  species.  There 
is  also  part  of  quantity,  into  which  any  quantity  is  divided. 
What  therefore  is  whole  in  any  place  by  totality  of  quantity. 


85  EXISTENCE  OF  GOD  IN  THINGS      Q.  8.  Art.  3 

cannot  be  outside  of  that  place,  because  the  quantity  of 
anything  placed  is  commensurate  to  the  quantity  of  the 
place  ;  and  hence  there  is  no  totality  of  quantity  without 
totality  of  place.  But  totality  of  essence  is  not  commen- 
surate to  the  totality  of  place.  Hence  it  is  not  necessary 
for  that  which  is  whole  by  totality  of  essence  in  a  thing,  not 
to  be  at  all  outside  of  it.  This  appears  also  in  accidental 
forms,  which  have  accidental  quantity ;  as  an  example,  white- 
ness is  whole  in  each  part  of  the  surface  if  we  speak  of  its 
totality  of  essence;  because  according  to  the  perfect  idea 
of  its  species  it  is  found  to  exist  in  every  part  of  the  surface. 
But  if  its  totality  be  considered  according  to  quantity  which 
it  has  accidentally,  then  it  is  not  whole  in  every  part  of  the 
surface.  On  the  other  hand  incorporeal  substances  have  no 
totality  either  of  themselves  or  accidentally,  except  in  refer- 
ence to  the  perfect  idea  of  their  essence.  Hence,  as  the  soul 
is  whole  in  every  part  of  the  body,  so  is  God  whole  in  all 
things  and  in  each  one. 

Third  Article. 

whether  god  is  everywhere  by  essence,  presence, 

and  power  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  the  mode  of  God's  existence  in 
all  things  is  not  properly  described  by  way  of  essence, 
presence,  and  power.  For  what  is  by  essence  in  anything, 
is  in  it  essentially.  But  God  is  not  essentially  in  things; 
for  He  does  not  belong  to  the  essence  of  anything.  There- 
fore it  ought  not  to  be  said  that  God  is  in  things  by  essence, 
presence,  and  power. 

Ohj.  2,  Further,  to  be  present  to  anything  means  not  to  be 
absent  from  it.  Now  this  is  the  meaning  of  God  being  in 
things  by  his  essence,  that  He  is  not  absent  from  anything. 
Therefore  the  presence  of  God  in  all  things  by  essence  and 
presence  means  the  same  thing.  Therefore  it  is  superfluous 
to  say  that  God  is  present  in  things  by  His  essence,  presence, 
and  power. 

Ohj.  3.  Further,  as  God  by  His  power  is  the  principle  of 


Q.  8.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  86 

all  things,  so  He  is  the  same  likewise  by  His  knowledge  and 
will.  But  it  is  not  said  that  He  is  in  things  by  knowledge 
and  will.     Therefore  neither  is  He  present  by  His  power. 

Ohj.  4.  Further,  as  grace  is  a  perfection  added  to  the 
substance  of  a  thing,  so  many  other  perfections  are  likewise 
added.  Therefore  if  God  is  said  to  be  in  certain  persons  in 
a  special  way  by  grace,  it  seems  that  according  to  every 
perfection  there  ought  to  be  a  special  mode  of  God's  existence 
in  things. 

On  the  contrary,  A  gloss  on  the  Canticle  of  Canticles,  v., 
says  that,  God  by  a  common  mode  is  in  all  things  by  His 
presence,  power,  aitd  substance;  still  He  is  said  to  be  present 
more  familiarly  in  some  by  grace.* 

I  answer  that,  God  is  said  to  be  in  a  thing  in  two  ways ;  in 
one  way  after  the  manner  of  an  efficient  cause;  and  thus  He 
is  in  all  things  created  by  Him;  in  another  way  He  is  in 
things  as  the  object  of  operation  is  in  the  operator;  and  this 
is  proper  to  the  operations  of  the  soul,  according  as  the  thing 
known  is  in  the  one  who  knows ;  and  the  thing  desired  in  the 
one  desiring.  In  this  second  way  God  is  especially  in  the 
rational  creature,  which  knows  and  loves  Him  actually  or 
habitually.  And  because  the  rational  creature  possesses 
this  prerogative  by  grace,  as  will  be  shown  later  (Q.  XII.), 
He  is  said  to  be  thus  in  tlie  saints  by  grace. 

But  how  He  is  in  other  things  created  by  Him,  may  be 
considered  from  human  affairs.  A  king,  for  example,  is 
said  to  be  in  the  whole  kingdom  by  his  power,  although  he 
is  not  everywhere  present.  Again  a  thing  is  said  to  be  by  its 
presence  in  other  things  which  are  subject  to  its  inspection; 
as  things  in  a  house  are  said  to  be  present  to  anyone,  who 
nevertheless  may  not  be  in  substance  in  every  part  of  the 
house.  Lastly  a  thing  is  said  to  be  by  way  of  substance 
or  essence  in  that  place  in  which  its  substance  may  be.  Now 
there  were  some  (the  Manichees)  who  said  that  spiritual 
and  incorporeal  things  were  subject  to  the  divine  power; 
but  that  visible  and  corporeal  things  were  subject  to  the 

*  The  quotation  is  from  S.  Gregory  {Horn.  viii.  in  Ezech.) 


Sj         EXISTENCE  OF  GOD  IN  THINGS      Q.  8.  Art.  3 

power  of  a  contrary  principle.     Therefore  against  these  it 
is  necessary  to  say  that  God  is  in  all  things  by  His  power. 

But  others,  though  they  believed  that  all  things  were 
subject  to  the  divine  power,  still  did  not  allow  that  divine 
providence  extended  to  these  inferior  bodies,  and  in  the 
person  of  these  it  is  said,  He  walketh  about  the  poles  of  the 
heavens;  and  He  doth  not  consider  our  things  *  (Job  xxii.  14). 
Against  these  it  is  necessary  to  say  that  God  is  in  all  things 
by  His  presence. 

Further,  others  said  that,  although  all  things  are  subject 
to  God's  providence,  still  all  things  are  not  immediately 
created  by  God;  but  that  He  immediately  created  the  first 
creatures,  and  these  created  the  others.  Against  these  it  is 
necessary  to  say  that  He  is  in  all  things  by  His  essence. 

Therefore,  God  is  in  all  things  by  His  power,  inasmuch  as 
all  things  are  subject  to  His  power;  He  is  by  His  presence 
in  all  things,  as  all  things  are  bare  and  open  to  His  eyes;  He 
is  in  all  things  by  His  essence,  inasmuch  as  He  is  present 
to  all  as  the  cause  of  their  being. 

Reply  Obj.  i.  God  is  said  to  be  in  all  things  by  essence, 
not  indeed  by  the  essence  of  the  things  themselves,  as  if 
He  were  of  their  essence;  but  by  His  own  essence;  because 
His  substance  is  present  to  all  things  as  the  cause  of  their 
being. 

Reply  Obj.  2.  A  thing  can  be  said  to  be  present  to  another, 
when  in  its  sight,  though  the  thing  may  be  distant  in 
substance,  as  was  shown  in  this  article;  and  therefore  two 
modes  of  presence  are  necessary;  viz.,  by  essence,  and  by 
presence. 

Reply  Obj.  3.  Knowledge  and  will  require  that  the  thing 
known  should  be  in  the  one  who  knows,  and  the  thing 
willed  in  the  one  who  wills.  Hence  by  knowledge  and  will 
things  are  more  truly  in  God  than  God  in  things.  But 
power  is  the  principle  of  acting  on  another;  hence  by  power 
the  agent  is  related  and  applied  to  an  external  thing; 
thus  by  power  an  agent  may  be  said  to  be  present  to 
another.

Reply  Ohj.  4.  No  other  perfection,  except  grace,  added  to 
substance,  renders  God  present  in  anything  as  the  object 
known  and  loved;  therefore  only  grace  constitutes  a  special 
mode  of  God's  existence  in  things.  There  is,  however, 
another  special  mode  of  God's  existence  in  man  by  union, 
which  will  be  treated  of  in  its  own  place  (Part  III.). 


Fourth  Article, 
whether  to  be  everywhere  belongs  to  god 

ALONE  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  to  be  everywhere  does  not 
belong  to  God  alone.  For  the  universal,  according  to  the 
Philosopher  {Poster,  i.),  is  everywhere,  and  always;  primary 
matter  also,  since  it  is  in  all  bodies,  is  everywhere.  But 
neither  of  these  is  God,  as  appears  from  what  is  said  above 
(Q.  III.).  Therefore  to  be  everywhere  does  not  belong  to 
God  alone. 

Ohj.  2.  Further,  number  is  in  things  numbered.  But  the 
whole  universe  is  constituted  in  number,  as  appears  from 
the  Book  of  Wisdom  (xi.  21).  Therefore  there  is  some 
number  which  is  in  the  whole  universe,  and  is  thus  every- 
where. 

Ohj.  3.  Further,  the  universe  is  a  kind  of  a  whole  perfect 
body  [Ccel.  et  Mund.  i.).  But  the  whole  universe  is  every- 
where, because  there  is  no  place  outside  of  it.  Therefore  to 
be  everywhere  does  not  belong  to  God  alone. 

Ohj.  4.  Further,  if  any  body  were  infinite,  no  place  would 
exist  outside  of  it,  and  so  it  would  be  everywhere.  Therefore 
to  be  everywhere  does  not  appear  to  belong  to  God  alone. 

Ohj.  5.  Further,  the  soul,  as  Augustine  says  {De  Trin.  vi.  6), 
is  whole  in  the  whole  hody,  and  whole  in  every  one  of  its  parts. 
Therefore  if  there  was  only  one  animal  in  the  world,  its 
soul  would  be  everywhere;  and  thus  to  be  everywhere  does 
not  belong  to  God  alone. 

Ohj.  6.  Further,  as  Augustine  says  [Ep.  cxxxvii).  The  soul 
feels  where  it  sees,  and  lives  where  it  feels,  and  is  where  it  lives. 


89  EXISTENCE  OF  GOD  IN  THINGS     Q.  8.  Art.  4 

But  the  soul  sees  as  it  were  everywhere :  for  in  a  succession  of 
glances  it  comprehends  the  entire  space  of  the  heavens  in  its 
sight.     Therefore  the  soul  is  everywhere. 

On  the  contrary,  Ambrose  says  {De  Spir.  Sand.  i.  7): 
Who  dares  to  call  the  Holy  Ghost  a  creature,  Who  in  all  things, 
and  everywhere,  and  always  is,  which  assuredly  belongs  to  the 
divinity  alone  ? 

I  answer  that,  To  be  everywhere  primarily  and  absolutely, 
is  proper  to  God.  Now  to  be  everywhere  primarily  is 
said  of  that  which  in  its  whole  self  is  everywhere;  for  if  a 
thing  were  everywhere  according  to  its  parts  in  different 
places,  it  would  not  be  primarily  everywhere,  forasmuch 
as  what  belongs  to  anything  according  to  part  does  not 
belong  to  it  primarily ;  thus  if  a  man  has  white  teeth,  white- 
ness belongs  primarily  not  to  the  man  but  to  his  teeth. 
But  a  thing  is  everywhere  absolutely  when  it  does  not 
belong  to  it  to  be  everywhere  accidentally,  that  is,  merely 
on  some  supposition;  as  a  grain  of  millet  would  be  every- 
where, supposing  that  no  other  body  existed.  It  belongs 
therefore  to  a  thing  to  be  everywhere  absolutely  when,  on 
any  supposition,  it  must  be  everywhere;  and  this  properly 
belongs  to  God  alone.  For  whatever  number  of  places  be 
supposed,  even  if  an  infinite  number  be  supposed  besides 
what  already  exist,  it  would  be  necessary  that  God  should 
be  in  all  of  them;  for  nothing  can  exist  except  by  Him. 
Therefore  to  be  everywhere  primarily  and  absolutely, 
belongs  to  God,  and  is  proper  to  Him:  because  whatever 
number  of  places  be  supposed  to  exist,  God  must  be  in  all 
of  them,  not  as  to  a  part  of  Him,  but  as  to  His  very  self. 

Reply  Obj.  i.  The  universal,  and  also  primary  matter  are 
indeed  everywhere;  but  not  according  to  the  same  mode 
of  existence. 

Reply  Obj.  2.  Number,  since  it  is  an  accident,  does  not,  of 
itself,  exist  in  place,  but  accidentally;  neither  is  the  whole 
but  only  part  of  it  in  each  of  the  things  numbered;  hence 
it  does  not  follow  that  it  is  primarily  and  absolutely  every- 
where. 

Reply  Obj.  3.  The  whole  body  of  the  universe  is  every- 


Q.  8.  Art.  4    THE  "  SUMMA  THEOLOGICA  ''  90 

where,  but  not  primarily;  forasmuch  as  it  is  not  wholly  in 
each  place,  but  according  to  its  parts;  nor  again  is  it  every- 
where absolutely,  because,  supposing  that  other  places 
existed  besides  itself,  it  would  not  be  in  them. 

Reply  Ohj.  4.  If  an  infinite  body  existed,  it  would  be 
everywhere;  but  according  to  its  parts. 

Reply  Ohj.  5.  Were  there  one  animal  only,  its  soul  would 
be  everywhere  primarily  indeed,  but  accidentally. 

Reply  Ohj.  6.  When  it  is  said  that  the  soul  seea  anywhere, 
this  can  be  taken  in  two  senses.  In  one  sense  the  adverb 
anywhere  determines  the  act  of  seeing  on  the  part  of  the 
object;  and  in  this  sense  it  is  true  that  while  it  sees  the 
heavens,  it  sees  in  the  heavens;  and  in  the  same  way  it  feels 
in  the  heavens ;  but  it  does  not  follow  that  it  lives  or  exists  in 
the  heavens,  because  to  live  and  to  exist  do  not  import  an 
act  passing  to  an  exterior  object.  In  another  sense  it  can  be 
understood  according  as  the  adverb  determines  the  act  of 
the  seer,  as  proceeding  from  the  seer;  and  thus  it  is  true  that 
where  the  soul  feels  and  sees,  there  it  is,  and  there  it  lives 
according  to  this  mode  of  speaking;  and  thus  it  does  not 
follow  that  it  is  everywhere. 


QUESTION  IX. 

THE  IMMUTABILITY  OF  GOD. 

{In  Two  Articles.) 

We  next  consider  God's  immutability,  and  His  eternity 
following  on  His  immutability. 

On  the  immutability  of  God  there  are  two  points  of 
inquiry :  (i)  Whether  God  is  altogether  immutable  ?  (2) 
Whether  to  be  immutable  belongs  to  God  alone  ? 

First  Article, 
whether  god  is  altogether  immutable  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  God  is  not  altogether  immut- 
able. For  whatever  moves  itself  is  in  some  way  mutable. 
But,  as  Augustine  says  {Gen.  ad  lit.  viii.  20),  The  Creator 
Spirit  moves  Himself  neither  by  time,  nor  by  place.  Therefore 
God  is  in  some  way  mutable. 

Obj.  2.  Further,  it  is  said  of  Wisdom,  that  it  is  more 
mobile  than  all  things  active — Vulg.  mobilior.  (Wisd.  vii.  24). 
But  God  is  wisdom  itself;  therefore  God  is  movable. 

Obj.  3.  Further,  to  approach  and  to  recede  signify  move- 
ment. But  these  are  said  of  God  in  Scripture,  Draw  nigh  to 
God,  and  He  will  draw  nigh  to  you  (James  iv.  8).  Therefore 
God  is  mutable. 

On  the  contrary,  It  is  written,  /  am  the  Lord,  and  I  change 
not  (Mai.  iii.  6). 

/  answer  that,  From  what  precedes,  it  is  shown  that  God 
is  altogether  immutable.  First,  because  it  was  shown 
above  that  there  is  some  first  being,  whom  we  call  God; 
and  that  this  first  being  must  be  pure  act,  without  the 

91  ' 


Q.q.Art.  I    THE  "  SUMMA  THEOLOGICA  "  92 

admixture  of  any  potentiality,  for  the  reason  that,  absolutely, 
potentiality  is  posterior  to  act.  Now  everything  which 
is  in  any  way  changed,  is  in  some  way  in  potentiality. 
Hence  it  is  evident  that  it  is  impossible  for  God  to  be  in 
any  way  changeable.  Secondly,  because  everything  which 
is  moved,  remains  as  it  was  in  part,  and  passes  away  in  part ; 
as  what  is  moved  from  whiteness  to  blackness,  remains  the 
same  as  to  suibstance;  thus  in  everything  which  is  moved, 
there  is  some  kind  of  composition  to  be  found.  But  it  has 
been  shown  above  (Q.  III.  A.  7.)  that  in  God  there  is  no  com- 
position, for  He  is  altogether  simple.  Hence  it  is  manifest 
that  God  cannot  be  moved.  Thirdly,  because  everything 
which  is  moved  acquires  something  by  its  movement,  and 
attains  to  what  it  had  not  attained  previously.  But  since 
God  is  infinite,  comprehending  in  Himself  all  the  plenitude 
of  perfection  of  all  being,  He  cannot  acquire  anything  new, 
nor  extend  Himself  to  anything  whereto  He  was  not  extended 
previously.  Hence  movement  in  no  way  belongs  to  Him.  So, 
some  of  the  ancients,  constrained,  as  it  were,  by  the  truth, 
decided  that  the  first  principle  was  immovable. 

Reply  Obj.  i.  Augustine  there  speaks  in  a  similar  way 
to  Plato,  who  said  that  the  first  mover  moves  Himself; 
calling  every  operation  a  movement,  even  as  the  acts  of 
understanding,  and  willing,  and  loving,  are  called  move- 
ments. Therefore  because  God  understands  and  loves  Him- 
self, in  that  respect  they  said  that  God  moves  Himself,  not, 
however,  as  movement  and  change  belong  to  a  thing  existing 
in  potentiality,  as  we  now  speak  of  change  and  movement. 

Reply  Obj.  2.  Wisdom  is  called  mobile  by  way  of  simili- 
tude, according  as  it  diffuses  its  likeness  even  to  the  outer- 
most of  things ;  for  nothing  can  exist  which  does  not  proceed 
from  the  divine  wisdom  by  way  of  some  kind  of  imitation, 
as  from  the  first  effective  and  formal  principle;  as  also  works 
of  art  proceed  from  the  wisdom  of  the  artist.  And  so  in  the 
same  way,  inasmuch  as  the  similitude  of  the  divine  wisdom 
proceeds  in  degrees  from  the  highest  things,  which  partici- 
pate more  fully  of  its  likeness,  to  the  lowest  things  which 
participate  of  it  in  a  lesser  degree,  there  is  said  be  a  kind  of 


93  THE  IMMUTABILITY  OF  GOD        Q.  9,  art.  2 

procession  and  movement  of  the  divine  wisdom  to  things ;  as 
when  we  say  that  the  sun  proceeds  to  the  earth,  inasmuch 
as  the  ray  of  Hght  touches  the  earth.  In  this  way  Dio- 
nysius  (C<s/.  Hier.  i.)  expounds  the  matter,  that  every  pro- 
cession of  the  divine  manifestation  comes  to  us  from  the 
movement  of  the  Father  of  light. 

Reply  Obj.  3.  These  things  are  said  of  God  in  Scripture 
metaphorically.  For  as  the  sun  is  said  to  enter  a  house, 
or  to  go  out,  according  as  its  rays  reach  the  house,  so  God 
is  said  to  approach  to  us,  or  to  recede  from  us,  when  we 
receive  the  influx  of  His  goodness,  or  decline  from  Him. 


Second  Article, 
whether  to  be  immutable  belongs  to  god  alone  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  to  be  immutable  does  not  belong 
to  God  alone.  For  the  Philosopher  says  [Metaph  ii.),  that 
matter  is  in  everything  which  is  moved.  But,  according  to 
some,  certain  created  substances,  as  angels  and  souls, 
have  not  matter.  Therefore  to  be  immutable  does  not 
belong  to  God  alone. 

Obj.  2.  Further,  everything  in  motion  moves  to  some  end. 
What  therefore  has  already  attained  its  ultimate  end,  is  not 
in  motion.  But  some  creatures  have  already  attained  to 
their  ultimate  end;  as  all  the  blessed  in  heaven.  Therefore 
some  creatures  are  immovable. 

Obj.  3.  Further,  everything  which  is  mutable,  is  variable. 
But  forms  are  invariable;  for  it  is  said  (Sex  Princip.  i.)  that 
form  is  essence  consisting  of  the  simple  and  invariable.  There- 
fore it  does  not  belong  to  God  alone  to  be  immutable. 

On  the  contrary,  Augustine  says  [De  Nat.  Boni.  i.),  God 
alone  is  immutable;  and  whatever  things  He  has  made,  being 
from  nothing,  are  mutable. 

I  answer  that,  God  alone  is  altogether  immutable;  whereas, 
every  creature  is  in  some  way  mutable.  Be  it  known  there- 
fore that  a  mutable  thing  can  be  called  so  in  two  ways :  by  a 
power  in  itself;  and  by  a  power  possessed  by  another.     For 


Q.  9.  Art.  2    THE  "  SUMMA  THEOLOGICA  ''  94 

all  creatures  before  they  existed,  were  possible,  not  by  any 
created  power,  since  no  creature  is  eternal,  but  by  the 
divine  power  alone,  inasmuch  as  God  could  produce  them 
into  existence.  Thus,  as  the  production  of  a  thing  into 
existence  depends  on  the  will  of  God,  so  likewise  it  depends 
on  His  will  that  things  should  be  preserved;  for  He  does 
not  preserve  them  otherwise  than  by  ever  giving  them 
existence;  hence  if  He  took  away  His  action  from  them,  all 
things  would  be  reduced  to  nothing,  as  appears  from  Augus- 
tine {Gen.  ad  lit.  iv.  12).  Therefore  as  it  was  in  the  Creator's 
power  to  produce  them  before  they  existed  in  themselves; 
so  likewise  it  is  in  the  Creator's  power  when  they  exist  in 
themselves  to  bring  them  to  nothing.  In  this  way  therefore, 
by  the  power  of  another — namely,  of  God — they  are  mutable, 
inasmuch  as  they  are  producible  from  nothing  by  Him,  and 
are  by  Him  reducible  from  existence  to  non-existence. 

If,  however,  a  thing  is  called  mutable  by  a  power  in  itself, 
thus  also  in  some  manner  every  creature  is  mutable.  For 
every  creature  has  a  twofold  power,  active  and  passive;  and 
I  call  that  power  passive  which  enables  anything  to  attain  its 
perfection  either  in  being,  or  in  attaining  to  its  end.  Now  if 
the  mutability  of  a  thing  be  considered  according  to  its 
power  for  being,  in  that  way  all  creatures  are  not  mutable, 
but  those  only  in  which  what  is  potential  in  them  is  con- 
sistent with  non-being.  Hence,  in  the  inferior  bodies 
there  is  mutability  both  as  regards  substantial  being,  inas- 
much as  their  matter  can  exist  with  privation  of  their 
substantial  form,  and  also  as  regards  their  accidental  being, 
supposing  the  subject  to  coexist  with  privation  of  accident; 
as,  for  example,  this  subject  man  can  exist  with  not-whiteness, 
and  can  therefore  be  changed  from  white  to  not-white. 
But  supposing  the  accident  to  be  such  as  to  follow  on  the 
essential  principles  of  the  subject,  then  the  privation  of 
such  an  accident  cannot  coexist  with  the  subject.  Hence 
the  subject  cannot  be  changed  as  regards  that  kind  of 
accident;  as,  for  example,  snow  cannot  be  made  black. 
Now  in  the  celestial  bodies  matter  is  not  consistent  with 
privation   of  form,   because  the  form  perfects  the  whole 


95  THE  IMMUTABILITY  OF  GOD    Q.  9.  Art.  2 

potentiality  of  the  matter;  therefore  these  bodies  are  not 
mutable  as  to  substantial  being,  but  only  as  to  locality, 
because  the  subject  is  consistent  with  privation  of  this  or 
that  place.  On  the  other  hand  incorporeal  substances,  being 
subsistent  forms  which,  although  with  respect  to  their  own 
existence  are  as  potentiality  to  act,  are  not  consistent  with 
the  privation  of  this  act;  forasmuch  as  existence  is  conse- 
quent upon  form,  and  nothing  corrupts  except  it  lose  its 
form.  Hence  in  the  form  itself  there  is  no  power  to  non- 
existence; and  so  these  kinds  of  substances  are  immutable 
and  invariable  as  regards  their  existence.  Wherefore 
Dionysius  says  (Div.  Nom.  iv.),  that  intellectual  created  sub- 
stances are  pure  from  generation  and  from  every  variation,  as 
also  are  incorporeal  and  immaterial  substances  Still,  there 
remains  in  them  a  twofold  mutability :  one  as  regards  their 
potentiality  to  their  end;  and  in  that  way  there  is  in  them  a 
mutability  according  to  choice  from  good  to  evil,  as  Dama- 
scene says  (De  Fide,  ii.  3,  4);  the  other  as  regards  place, 
inasmuch  as  by  their  finite  power  they  attain  to  certain  fresh 
places — which  cannot  be  said  of  God,  who  by  His  infinity 
fills  all  places,  as  was  shown  above  (Q.  VIII.  A.  2.). 

Thus  in  every  creature  there  is  a  potentiahty  to  change 
either  as  regards  substantial  being  as  in  the  case  of  things 
corruptible;  or  as  regards  locality  only,  as  in  the  case  of 
the  celestial  bodies;  or  as  regards  the  order  to  their  end, 
and  the  application  of  their  powers  to  divers  objects,  as  is 
the  case  with  the  angels;  and  universally  all  creatures 
generally  are  mutable  by  the  power  of  the  Creator,  in  Whose 
power  is  their  existence  and  non-existence.  Hence  since 
God  is  in  none  of  these  ways  mutable,  it  belongs  to  Him 
alone  to  be  altogether  immutable. 

Reply  Obj.  i.  This  objection  proceeds  from  mutability 
as  regards  substantial  or  accidental  being;  for  philosophers 
treated  of  such  movement. 

Reply  Obj,  2.  The  good  angels,  besides  their  natural 
endowment  of  immutability  of  being,  have  also  immuta- 
bility of  election  by  divine  power;  nevertheless  there 
remains  in  them  mutability  as  regards  place. 


Q.  9.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  96 

Reply  Obj.  3.  Forms  are  called  invariable,  forasmuch  as 
they  cannot  be  subjects  of  variation  ;  but  they  are  subject 
to  variation  because  by  them  their  subject  is  variable. 
Hence  it  is  clear  that  they  vary  in  so  far  as  they  are;  for 
they  are  not  called  beings  as  though  they  were  the  subject 
of  being,  but  because  through  them  something  has  being. 


QUESTION  X. 

THE  ETERNITY  OF  GOD. 
{In  Six  Articles.) 

We  must  now  consider  the  eternity  of  God,  concerning 
which  arise  six  points  of  inquiry :  (i)  What  is  eternity  ?  (2) 
Whether  God  is  eternal  ?  (3)  Whether  to  be  eternal  belongs 
to  God  alone  ?  (4)  Whether  eternity  differs  from  time  ? 
(5)  The  difference  of  aeviternity  and  of  time.  (6)  Whether 
there  is  only  one  aeviternity,  as  there  is  one  time,  and  one 
eternity  ? 

First  Article. 

whether  this  is  a  good  definition  of  eternity,  '  the 
simultaneously-whole  and  perfect  possession  of 
interminable  life  '? 

We  proceed  thus  to  the  First  Article: — 

Objection  i.  It  seems  that  the  definition  of  eternity  given 
by  Boethius  {De  Consol.  v.)  is  not  a  good  one:  '  Eternity  is 
the  simultaneously-whole  and  perfect  possession  of  inter- 
minable life.'  For  the  word  interminable  is  a  negative  one. 
But  negation  only  belongs  to  what  is  defective,  and  this 
does  not  belong  to  eternity.  Therefore  in  the  definition  of 
eternity  the  word  interminable  ought  not  to  be  found. 

Obj,  2.  Further,  eternity  signifies  a  certain  kind  of 
duration.  But  duration  regards  existence  rather  than  life. 
Therefore  the  word  life  ought  not  to  come  into  the  defini- 
tion of  eternity;  but  rather  the  word  existence. 

Obj.  3.  Further,  a  whole  is  what  has  parts.  But  this  is 
alien  to  eternity,  which  is  simple.  Therefore  it  is  im- 
properly said  to  be  whole. 

T.  91  7 


Q.  lo.  Art.  i    THE  *'  SUMMA  THEOLOGICA  "  9^ 

Obj.  4.  Many  days  cannot  occur  together,  nor  can  many 
times  exist  all  at  once.  But  in  eternity  days  and  times  are 
in  the  plural,  for  it  is  said,  His  going  forth  is  from  the  begin- 
ning, from  the  days  of  eternity  (Mic.  v.  2) ;  and  also  it  is 
said,  According  to  the  revelation  of  the  mystery  hidden  from 
eternity  (Rom.  xvi.  25).  Therefore  eternity  is  not  omni- 
simultaneous. 

Obj.  5.  Further,  the  whole  and  the  perfect  are  the  same 
thing.  Supposing,  therefore,  that  it  is  whole,  it  is  super- 
fluously described  as  perfect. 

Obj.  6.  Further,  duration  does  not  imply  possession.  But 
eternity  is  a  kind  of  duration.  Therefore  eternity  is  not 
possession. 

/  answer  that,  As  we  attain  to  the  knowledge  of  simple 
things  by  way  of  compound  things,  so  we  must  reach  to  the 
knowledge  of  eternity  by  means  of  time,  which  is  nothing 
but  the  numbering  of  movement  by  before  and  after.  For 
since  succession  occurs  in  every  movement,  and  one  part 
comes  after  another,  the  fact  that  we  reckon  before  and  after 
in  movement,  makes  us  apprehend  time,  which  is  nothing 
else  but  the  measure  of  before  and  after  in  movement.  Now 
in  a  thing  bereft  of  movement,  which  is  always  the  same, 
there  is  no  before  and  after.  As  therefore  the  idea  of  time 
consists  in  the  numbering  of  before  and  after  in  movement ; 
so  likewise  in  the  apprehension  of  the  uniformity  of  what  is 
outside  of  movement,  consists  the  idea  of  eternity. 

Further,  those  things  are  said  to  be  measured  by  time 
which  have  a  beginning  and  an  end  in  time,  because  in 
everything  which  is  moved  there  is  a  beginning,  and  there 
is  an  end.  But  as  whatever  is  wholly  immutable  can  have 
no  succession,  so  it  has  no  beginning,  and  no  end. 

Thus  eternity  is  known  from  two  sources:  first,  because 
what  is  eternal  is  interminable — that  is,  has  no  beginning  nor 
end  (that  is,  no  term  either  way) ;  secondly,  because  eternity 
has  no  succession,  being  simultaneously  whole. 

Reply  Obj.  i.  Simple  things  are  usually  defined  by  way  of 
negation ;  as  *  a  point  is  that  which  has  no  parts.'  Yet  this 
is  not  to  be  taken  as  if  the  negation  belonged  to  their

essence,  but  because  our  intellect  which  first  apprehends 
compound  things,  cannot  attain  to  the  knowledge  of  simple 
things  except  by  removing  the  composite. 

Reply  Obj.  2.  What  is  truly  eternal,  is  not  only  being,  but 
also  living;  and  life  extends  to  operation,  which  is  not 
true  of  being.  Now  the  protraction  of  duration  seems  to 
belong  to  operation  rather  than  to  being ;  hence  time  is  the 
numbering  of  movement. 

Reply  Obj.  3.  Eternity  is  called  whole,  not  because  it 
has  parts,  but  because  it  is  wanting  in  nothing. 

Reply  Obj.  /\.  As  God,  although  incorporeal,  is  named  in 
Scripture  metaphorically  by  corporeal  names,  so  eternity 
though  simultaneously  whole,  is  called  by  names  implying 
time  and  succession. 

Reply  Obj.  5.  Two  things  are  to  be  considered  in  time: 
time  itself,  which  is  successive;  and  the  now  of  time,  which 
is  imperfect.  Hence  the  expression  simultaneously -whole  is 
used  to  remove  the  idea  of  time,  and  the  word  perfect  is 
used  to  exclude  the  now  of  time. 

Reply  Obj.  6.  Whatever  is  possessed,  is  held  firmly  and 
quietly ;  therefore  to  designate  the  immutability  and  perma- 
nence of  eternity,  we  use  the  word  possession. 

Second  Article, 
whether  god  is  eternal  ? 

We  proceed  thus  to  the  Second  Article : — 

Objection  i.  It  seems  that  God  is  not  eternal.  For 
nothing  made  can  be  predicated  of  God.  But  eternity  is 
a  thing  made;  for  Boethius  says  (De  Trin.  iv.)  that.  The  now 
that  flows  away  makes  time,  the  now  that  stands  still  makes 
eternity;  and  Augustine  says  (Octog.  Tri.  QucBst.qu.  28)  that 
God  is  the  author  of  eternity.     Therefore  God  is  not  eternal. 

Obj.  2.  Further,  what  is  before  eternity,  and  after  eternity, 
is  not  measured  by  eternity.  But,  as  Aristotle  says  {De  Caus) , 
God  is  before  eternity  and  He  is  after  eternity:  for  it  is  written 
that  the  Lord  shall  reign  for  eternity,  and  beyond  *  (Exod,  xv, 
18) .     Therefore  to  be  eternal  does  not  belong  to  God. 

*  Douay, — for  ever  and  ever. 


Q.  lo.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  100 

Ohj.  3.  Further,  eternity  is  a  kind  of  measure.  But  to  be 
measured  belongs  not  to  God.  Therefore  it  does  not  belong 
to  Him  to  be  eternal. 

Ohj,  4.  Further,  in  eternity  there  is  no  present,  past,  nor 
future,  since  it  is  simultaneously  whole;  as  was  said  in  the 
preceding  article.  But  words  denoting  present,  past,  and 
future  time  are  applied  to  God  in  Scripture .  Therefore  God 
is  not  eternal. 

On  the  contrary,  Athanasius  says  in  his  Creed :  The  Father 
is  eternal,  the  Son  is  eternal,  the  Holy  Ghost  is  eternal. 

I  answer  that.  The  idea  of  eternity  follows  immutability, 
as  the  idea  of  time  follows  movement,  as  appears  from  the 
preceding  article.  Hence,  as  God  is  supremely  immutable, 
it  supremely  belongs  to  Him  to  be  eternal.  Nor  is  He 
eternal  only;  but  He  is  His  own  eternity;  whereas,  no 
other  being  is  its  own  duration,  as  no  other  is  its  own  being. 
Now  God  is  His  own  uniform  being ;  and  hence,  as  He  is  His 
own  essence,  so  He  is  His  own  eternity. 

Reply  Ohj.  i.  The  now  that  stands  still,  is  said  to  make 
eternity  according  to  our  apprehension.  As  the  appre- 
hension of  time  is  caused  in  us  by  the  fact  that  we  appre- 
hend the  flow  of  the  now;  so  the  apprehension  of  eternity 
is  caused  in  us  by  our  apprehending  the  now  standing  still. 
When  Augustine  says  that  God  is  the  author  of  eternity,  this 
is  to  be  understood  of  participated  eternity.  For  God 
communicates  His  eternity  to  some  in  the  same  way  as  He 
communicates  His  immutability. 

Reply  Ohj.  2.  From  this  appears  the  answer  to  the  second 
objection.  For  God  is  said  to  be  before  eternity,  accord- 
ing as  it  is  shared  by  immaterial  substances.  Hence,  also, 
in  the  same  book,  it  is  said  that  intelligence  is  equal  to 
eternity.  In  the  words  of  Exodus,  The  Lord  shall  reign 
for  eternity,  and  heyond,  eternity  stands  for  age,  as  another 
rendering  has  it.  Thus,  it  is  said  that  the  Lord  will  reign 
beyond  eternity,  inasmuch  as  He  endures  beyond  every 
age,  that  is,  beyond  every  kind  of  given  duration.  For  age 
is  nothing  more  than  the  period  of  each  thing,  as  is  said  in 
the  book  De  Ccelo  i.     Or  to  reign  beyond  eternity  can  be

taken  to  mean  that  if  any  other  thing  were  conceived  to 
exist  for  ever,  as  the  movement  of  the  heavens  according 
to  some  philosophers,  then  God  would  still  reign  beyond, 
inasmuch  as  His  reign  is  simultaneously  whole. 

Reply  Ohj.  3.  Eternity  is  nothing  else  but  God  Himself. 
Hence  God  is  not  called  eternal,  as  if  He  were  in  any  way 
measured;  but  the  idea  of  measurement  is  there  taken 
according  to  the  apprehension  of  our  mind  alone. 

Reply  Ohj,  4.  Words  denoting  different  times  are  applied 
to  God,  because  His  eternity  includes  all  times ;  not  as  if  He 
Himself  were  altered  through  present,  past,  and  future. 

Third  Article, 
whether  to  be  eternal  belongs  to  god  alone  ? 

We  proceed  thus  to  the  Third  Article: — 

Objection  i.  It  seems  that  it  does  not  belong  to  God  alone 
to  be  eternal.  For  it  is  written,  that  those  who  instruct  many 
to  justice,  shall  be  as  stars  unto  perpetual  eternities  *  (Dan. 
xii.  3).  Now  if  God  alone  were  eternal,  there  could  not  be 
many  eternities.   Therefore  God  alone  is  not  the  only  eternal. 

Ohj.  2.  Further,  it  is  written,  Depart,  ye  cursed,  into  eternal 
(Douay,  everlasting)  fire  (Matt.  xxv.  41).  Therefore  God  is 
not  the  only  eternal. 

Ohj,  3.  Further,  every  necessary  thing  is  eternal.  But 
there  are  many  necessary  things;  as,  for  instance,  all  prin- 
ciples of  demonstration,  and  all  demonstrative  propositions. 
Therefore  God  is  not  the  only  eternal. 

On  the  contrary,  Jerome  says  (Ep.  ad  Damasum,  xv.)  that 
God  is  the  only  one  who  has  no  beginning.  Now  whatever 
has  a  beginning,  is  not  eternal.  Therefore  God  is  the  only 
one  eternal. 

/  answer  that,  Eternity  truly  and  properly  so  called  is 
in  God  alone,  because  eternity  follows  on  immutability; 
as  appears  from  the  first  article.  But  God  alone  is  alto- 
gether immutable,  as  was  shown  above  (Q.  IX.  A.  i). 
Accordingly,  however,  as  some  receive  immutability  from 

*  Douay, — for  all  eternity. 


Q.  lo.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  102 

Him,  they  share  in  His  eternity.  Thus  some  receive 
immutabihty  from  God  in  the  way  of  never  ceasing  to 
exist;  in  that  sense  it  is  said  of  the  earth,  that  it  standeth 
for  ever  (Eccl.  i.  4).  Again  some  things  are  called  eternal 
in  Scripture  because  of  the  length  of  their  duration,  although 
they  are  in  nature  corruptible;  thus  (Ps.  Ixxv.  5)  the  hills 
are  called  eternal,  and  we  read  of  the  fruits  of  the  eternal  hills 
(Deut.  xxxiii.  15).  Some  again,  share  more  fully  than  others 
in  the  nature  of  eternity,  inasmuch  as  they  possess  unchange- 
ableness  either  in  being  or  further  still  in  operation ;  like  the 
angels,  and  the  blessed,  who  enjoy  the  Word,  because  as 
regards  that  vision  of  the  Word,  no  changing  thoughts  exist  in 
the  Saints,  as  Augustine  says  (De  Trin.  xv.).  Hence  those 
who  see  God  are  said  to  have  eternal  life ;  according  to  that 
text,  This  is  eternal  life,  that  they  may  know  Thee  the  only 
true  God,  etc.  (John  xvii.  3). 

Reply  Ohj.  i.  There  are  said  to  be  many  eternities, 
accordingly  as  many  share  in  eternity,  by  the  contempla- 
tion of  God. 

Reply  Ohj.  2.  The  fire  of  hell  is  called  eternal,  only  because 
it  never  ends.  Still,  there  is  change  in  the  pains  of  the  lost, 
according  to  the  words.  To  extreme  heat  they  will  pass  from 
snowy  waters  (Job  xxiv.  19).  Hence  in  hell  true  eternity 
does  not  exist,  but  rather  time ;  according  to  the  text  of  the 
Psalm,  Their  time  will  he  for  ever  (Ps.  Ixxx.  16). 

Reply  Ohj.  3.  Necessary  means  a  certain  mode  of  truth: 
and  truth,  according  to  the  Philosopher  (Metaph.  vi.),  is  in 
the  mind.  Therefore  in  this  sense  the  true  and  necessary 
are  eternal,  because  they  are  in  the  eternal  mind,  which  is 
the  divine  intellect  alone;  hence  it  does  not  follow  that 
anything  beside  God  is  eternal. 

Fourth  Article, 
whether  eternity  differs  from  time  } 

We  proceed  thus  to  the  Fourth  Article: — 

Ohjection  i.  It  seems  that  eternity  does  not  differ  from 
time.  For  two  measures  of  duration  cannot  exist  together, 
unless  one  is  part  of  the  other;  for  instance  two  days  or  two 


103  THE  ETERNITY  OF  GOD        Q.  lo.  Art.  4 

hours  cannot  be  together;  nevertheless,  we  may  say  that  a 
day  and  an  hour  are  together,  considering  hour  as  part  of  a 
day.  But  eternity  and  time  occur  together,  each  of  which 
imports  a  certain  measure  of  duration.  Since  therefore 
eternity  is  not  a  part  of  time,  forasmuch  as  eternity  exceeds 
time,  and  includes  it,  it  seems  that  time  is  a  part  of  eternity, 
and  is  not  a  different  thing  from  eternity. 

Ohj.  2.  Further,  according  to  the  Philosopher  {Physic,  iv.), 
the  now  of  time  remains  the  same  in  the  whole  of  time.  But 
the  nature  of  eternity  seems  to  be  that  it  is  the  same  indi- 
visible thing  in  the  whole  space  of  time.  Therefore  eternity 
is  the  now  of  time.  But  the  now  of  time  is  not  substantially 
different  from  time.  Therefore  eternity  is  not  substantially 
different  from  time. 

Ohj.  3.  Further,  as  the  measure  of  the  first  movement  is 
the  measure  of  every  movement,  as  said  in  Physic,  iv.,  it  thus 
appears  that  the  measure  of  the  first  being  is  that  of  every 
being.  But  eternity  is  the  measure  of  the  first  being — that 
is,  of  the  divine  being.  Therefore  eternity  is  the  measure 
of  every  being.  But  the  being  of  things  corruptible  is 
measured  by  time.  Time  therefore  is  either  eternity,  or  is 
a  part  of  eternity. 

On  the  contrary,  Eternity  is  simultaneously  whole.  But 
time  has. a  before  and  an  after.  Therefore  time  and 
eternity  are  not  the  same  thing. 

I  answer  that,  It  is  manifest  that  time  and  eternity  are 
not  the  same.  Some  have  founded  this  difference  on  the 
fact  that  eternity  has  neither  beginning  nor  an  end;  whereas 
time  has  a  beginning  and  an  end.  This,  however,  makes  a 
merely  accidental,  and  not  an  absolute  difference;  because, 
granted  that  time  always  was  and  always  will  be,  according 
to  the  idea  of  those  who  think  the  movement  of  the  heavens 
goes  on  for  ever,  there  would  yet  remain  a  difference  between 
eternity  and  time,  as  Boethius  says  {De  Consol.  v.),  arising 
from  the  fact  that  eternity  is  simultaneously  whole;  which 
cannot  be  applied  to  time:  for  eternity  is  the  measure  of  a  v 
permanent  being ;  while  time  is  the  measure  of  movement.  ^ 
Supposing,  however,  that  the  aforesaid  difference  be  con- 


Q  lo.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  104 

sidered  on  the  part  of  the  things  measured,  and  not  as 
regards  the  measures,  then  there  is  some  reason  for  it,  inas- 
much as  that  alone  is  measured  by  time  which  has  beginning 
and  end  in  time.  Hence,  if  the  movement  of  the  heavens 
lasted  always,  time  would  not  be  its  measure  as  regards  the 
whole  of  its  duration,  since  the  infinite  is  not  measurable; 
but  it  would  be  the  measure  of  that  part  of  its  revolution 
which  has  beginning  and  end  in  time. 

Another  reason  for  the  same  can  be  taken  from  these 
measures  in  themselves,  if  we  consider  the  end  and  the 
beginning  as  potentialities;  because,  granted  also  that  time 
always  goes  on,  yet  it  is  possible  to  note  in  time  both  the 
beginning  and  the  end,  by  considering  its  parts : — thus  we 
speak  of  the  beginning  and  the  end  of  a  day,  or  of  a  year ; 
which  cannot  be  applied  to  eternity.  Still  these  differences 
follow  upon  the  essential  and  primary  differences,  that  eter- 
nity is  simultaneously  whole,  but  that  time  is  not  so. 

Reply  Obj.  i.  Such  a  reason  would  be  a  valid  one  if  time 
and  eternity  were  the  same  kind  of  measure;  but  this  is 
seen  not  to  be  the  case  when  we  consider  those  things  of 
which  the  respective  measures  are  time  and  eternity. 

Reply  Obj.  2.  The  now  of  time  is  the  same  as  regards  its 
subject  in  the  whole  course  of  time,  but  it  differs  in  aspect; 
for  inasmuch  as  time  corresponds  to  movement,  its  now  corre- 
sponds to  what  is  movable;  and  the  thing  movable  has 
the  same  one  subject  in  all  time,  but  differs  in  aspect  as  being 
here  and  there ;  and  such  alternation  is  movement.  Likewise 
the  flow  of  the  now  as  alternating  in  aspect,  is  time.  But 
eternity  remains  the  same  according  to  both  subject  and 
aspect;  and  hence  eternity  is  not  the  same  as  the  now  of 
time. 

Reply  Obj.  3.  As  eternity  is  the  proper  measure  of  per- 
manent being,  so  time  is  the  proper  measure  of  movement; 
and  hence,  according  as  any  being  recedes, from  permanence 
of  being,  and  is  subject  to  change,  it  recedes  from  eternity, 
and  is  subject  to  time.  Therefore  the  being  of  things 
corruptible,  because  it  is  changeable,  is  not  measured  by 
eternity,  but  by  time;  for  time  measures  not  only  things 


105  THE  ETERNITY  OF  GOD       Q.  lo.  Art.  5 

actually  changed,  but  also  things  changeable;  hence  it  not 
only  measures  movement,  but  it  also  measures  repose,  which 
belongs  to  whatever  is  naturally  movable,  but  is  not  actually 
in  motion. 

Fifth  Article, 
the  difference  of  ieviternity  and  time. 

We  proceed  thus  to  the  Fifth  Article : — 

Obj.  I.  It  seems  that  seviternity  is  the  same  as  time. 
For  Augustine  says  (Gen.  ad.  lit.  viii.  20,  22,  23),  that  God 
moves  the  spiritual  creature  through  time.  But  aeviternity  is 
said  to  be  the  measure  of  spiritual  substances.  Therefore 
time  is  the  same  as  aeviternity. 

Obj.  2.  Further,  it  is  essential  to  time  to  have  before 
and  after;  but  it  is  essential  to  eternity  to  be  simultaneously 
whole,  as  was  shown  above  in  the  first  article.  Now 
seviternity  is  not  eternity;  for  it  is  written  (Ecclus.i.  i), 
that  eternal  Wisdom  is  before  age.  Therefore  it  is  not 
simultaneously  whole  but  has  before  and  after;  and  thus  it 
is  the  same  as  time. 

Obj.  3.  Further,  if  there  is  no  before  and  after  in  sevi- 
ternity, it  follows  that  in  seviternal  things  there  is  no  differ- 
ence between  being,  having  been,  or  going  to  be.  Since 
then  it  is  impossible  for  seviternal  things  not  to  have  been, 
it  follows  that  it  is  impossible  for  them  not  to  be  in  the 
future;  which  is  false,  since  God  can  reduce  them  to  nothing. 

Obj.  4.  Further,  since  the  duration  of  seviternal  things  is 
infinite  as  to  subsequent  duration,  if  seviternity  is  simul- 
taneously whole,  it  follows  that  some  creature  is  actually 
infinite;  which  is  impossible.  Therefore  seviternity  does 
not  differ  from  time. 

On  the  contrary,  Boethius  says  (De.  Consol.  iii),  Who 
commandest  time  to  be  separate  from  ceviternity. 

I  answer  that,  iEviternity  differs  from  time,  and  from 
eternity,  as  the  mean  between  them  both.  This  difference 
is  explained  by  some  to  consist  in  the  fact  that  eternity 
has  neither  beginning  nor  end,  aeviternity,  a  beginning  but 
no  end,  and  time  both  beginning  and  end.     This  difference, 


Q.  lo.  Art.  5    THE  "  SUMMA  THEOLOGICA  "  106 

however,  is  but  an  accidental  one,  as  was  shown  above,  in 
the  preceding  article;  because  even  if  seviternal  things  had 
always  been,  and  would  always  be,  as  some  think,  and 
even  if  they  might  sometimes  fail  to  be,  which  is  possible 
to  God  to  allow;  even  granted  this,  aeviternity  would  still 
be  distinguished  from  eternity,  and  from  time. 

Others  assign  the  difference  between  these  three  to  consist 
in  the  fact  that  eternity  has  no  before  and  after;  but  that 
time  has  both,  together  with  innovation  and  veteration; 
and  that  aeviternity  has  before  and  after  without  innovation 
and  veteration.  This  theory,  however,  involves  a  con- 
tradiction; which  manifestly  appears  if  innovation  and 
veteration  be  referred  to  the  measure  itself.  For  since 
before  and  after  of  duration  cannot  exist  together,  if  aevi- 
ternity has  before  and  after,  it  must  follow  that  with  the 
receding  of  the  first  part  of  aeviternity,  the  after  part  of 
aeviternity  must  newly  appear ;  and  thus  innovation  would 
occur  in  aeviternity  itself,  as  it  does  in  time.  And  if  they  be 
referred  to  the  things  measured,  even  then  an  incongruity 
would  follow.  For  a  thing  which  exists  in  time  grows  old 
with  time,  because  it  has  a  changeable  existence,  and  from 
the  changeableness  of  a  thing  measured,  there  follows  before 
and  after  in  the  measure,  as  is  clear  from  Physic,  iv.  There- 
fore the  fact  that  an  aeviternal  thing  is  neither  inveterable, 
nor  subject  to  innovation,  comes  from  its  changelessness ; 
and  consequently  its  measure  does  not  contain  before  and 
after.  We  say  then  that  since  eternity  is  the  measure  of  a 
permanent  being,  in  so  far  as  anything  recedes  from  per- 
manence of  being,  it  recedes  from  eternity.  Now  some 
things  recede  from  permanence  of  being,  so  that  their 
being  is  subject  to  change,  or  consists  in  change;  and  these 
things  are  measured  by  time,  as  are  all  movements,  and 
also  the  being  of  all  things  corruptible.  But  others  recede 
less  from  permanence  of  being,  forasmuch  as  their  being 
neither  consists  in  change,  nor  is  the  subject  of  change; 
nevertheless  they  have  change  annexed  to  them  either 
actually,  or  potentially.  This  appears  in  the  heavenly 
bodies,  the  substantial  being  of  which  is  unchangeable; 


107  THE  ETERNITY  OF  GOD       Q.  lo.  Art.  5 

and  yet  with  unchangeable  being  they  have  changeable- 
ness  of  place.  The  same  applies  to  the  angels,  who  have 
an  unchangeable  being  as  regards  their  nature  with  change- 
ableness  as  regards  choice ;  moreover  they  have  changeable- 
ness  of  intelligence,  of  affections,  and  of  places,  in  their 
own  degree.  Therefore  these  are  measured  by  aeviternity, 
which  is  a  mean  between  eternity  and  time.  But  the  being 
that  is  measured  by  eternity  is  not  changeable,  nor  is  it 
annexed  to  change.  In  this  way  time  has  before  and  after; 
aeviternity  in  itself  has  no  before  and  after,  which  can, 
however,  be  annexed  to  it ;  while  eternity  has  neither  before 
nor  after,  nor  is  it  compatible  with  such  at  all. 

Reply  Obj.  i.  Spiritual  creatures  as  regards  successive 
affections  and  intelligences,  are  measured  by  time.  Hence 
also  Augustine  says  (ibid.),  that  to  be  moved  through  time, 
is  to  be  moved  by  affections.  But  as  regards  their  nature 
they  are  measured  by  aeviternity;  whereas  as  regards  the 
vision  of  glory,  they  have  a  share  of  eternity. 

Reply  Obj.  2.  ^viternity  is  simultaneously  whole;  yet  it  is 
not  eternity,  because  before  and  after  are  compatible  with  it. 

Reply  Obj.  3.  In  the  very  being  of  an  angel  considered 
absolutely,  there  is  no  difference  of  past  and  future,  but  only 
as  regards  accidental  changes.  Now  to  say  that  an  angel 
was,  or  is,  or  will  be,  is  to  be  taken  in  a  different  sense 
according  to  the  acceptation  of  our  intellect,  which  appre- 
hends the  angelic  existence  by  comparison  with  different 
parts  of  time.  But  when  we  say  that  an  angel  is,  or  was,  we 
suppose  something,  which  being  supposed,  its  opposite  is 
not  subject  to  the  divine  power.  Whereas  when  we  say  he 
will  be,  we  do  not  as  yet  suppose  anything.  Hence,  since 
the  existence  and  non-existence  of  an  angel  considered  abso- 
lutely is  subject  to  the  divine  power,  God  can  make  the 
existence  of  an  angel  not  future;  but  He  cannot  cause  him 
not  to  be  while  he  is,  or  not  to  have  been,  after  he  has  been. 

Reply  Obj.  4.  The  duration  of  aeviternity  is  infinite,  for- 
asmuch as  it  is  not  finished  by  time.  Hence,  there  is  no 
incongruity  in  saying  that  a  creature  is  infinite,  inasmuch 
as  it  is  not  ended  by  any  other  creature. 


Q.  lo.  Art.  6    THE  "  SUMMA  THEOLOGICA  "  io8 

Sixth  Article, 
whether  there  is  only  one  ^viternity  ? 

We  proceed  thus  to  the  Sixth  Article: — 

Objection  i.  It  seems  that  there  is  not  only  one  seviternity ; 
for  it  is  written  in  the  apocryphal  books  of  Esdras:  Majesty 
and  power  of  ages  are  with  Thee,  0  Lord. 

Obj.  2.  Further,  different  genera  have  different  measures. 
But  some  seviternal  things  belong  to  the  corporeal  genus,  as 
the  heavenly  bodies;  and  others  are  spiritual  substances,  as 
the  angels.     Therefore  there  is  not  only  one  seviternity. 

Obj,  3.  Further,  since  seviternity  is  a  term  of  duration, 
where  there  is  one  seviternity,  there  is  also  one  duration. 
But  not  all  seviternal  things  have  one  duration,  for  some 
begin  to  exist  after  others;  as  appears  in  the  case  especially 
of  human  souls.    Therefore  there  is  not  only  one  seviternity. 

Obj.  4.  Further,  things  not  dependent  on  each  other,  do 
not  seem  to  have  one  measure  of  duration ;  for  there  appears 
to  be  one  time  for  all  temporal  things;  since  the  first  move- 
ment, measured  by  time,  is  in  some  way  the  cause  of  all 
movement.  But  seviternal  things  do  not  depend  on  each 
other,  for  one  angel  is  not  the  cause  of  another  angel. 
Therefore  there  is  not  only  one  seviternity. 

On  the  contrary,  ^Eviternity  is  a  more  simple  thing  than 
time,  and  is  nearer  to  eternity.     But  time  is  one  only 
Therefore  much  more  is  seviternity  one  only. 

/  answer  that,  A  twofold  opinion  exists  on  this  subject. 
Some  say  there  is  only  one  seviternity;  others  that  there  are 
many  seviternities.  Which  of  these  is  true,  may  be  con- 
sidered from  the  cause  why  time  is  one ;  for  we  can  rise  from 
corporeal  things  to  the  knowledge  of  spiritual  things. 

Now  some  say  that  there  is  only  one  time  for  temporal 
things,  forasmuch  as  one  number  exists  for  all  things 
numbered ;  as  time  is  a  number,  according  to  the  Philosopher 
{Physic,  iv. ).  This,  however,  is  not  a  sufficient  reason ;  because 
time  is  not  a  number  abstracted  from  the  thing  numbered, 
but  existing  in  the  thing  numbered;  otherwise  it  would 


109  THE  ETERNITY  OF  GOD        Q.  lo.  Art.  6 

not  be  continuous;  for  ten  ells  of  cloth  are  continuous  not 
by  reason  of  the  number,  but  by  reason  of  the  thing  num- 
bered.    Now  number  as  it  exists  in  the  thing  numbered,  is 
not  the  same  for  all;  but  is  different  for  different  things. 
Hence,  others  assert  that  the  unity  of  eternity  as  the  principle 
of  all  duration  is  the  cause  of  the  unity  of  time.     Thus  all 
durations  are  one  in  that  view,  in  the  light  of  their  principle, 
but  are  many  in  the  light  of  the  diversity  of  things  receiving 
duration  from  the  influx  of  the  first  principle.     On  the 
other  hand  others  assign  primary  matter  as  the  cause  why 
time  is  one ;  as  it  is  the  first  subject  of  movement,  the  measure 
of  which  is  time.     Neither  of  these  reasons,  however,  is 
sufficient;  forasmuch  as  things  which  are  one  in  principle, 
or  in  subject,  especially  if  distant,  are  not  one  absolutely, 
but   accidentally.     Therefore   the   true   reason   why   time 
is  one,  is  to  be  found  in  the  oneness  of  the  first  movement 
by  which,  since  it  is  most  simple,  all  other  movements  are 
measured.     Therefore  time  is  referred  to  that  movement,  not 
only  as  a  measure  is  to  the  thing  measured,  but  also  as 
accident  is  to  subject;  and  thus  receives  unity  from  it. 
Whereas  to  other  movements  it  is  compared  only  as  the 
measure  is  to  the  thing  measured.     Hence  it  is  not  multi- 
plied by  their  multitude,  because  by  one  separate  measure 
many  things  can  be  measured. 

This  being  established,  we  must  observe  that  a  twofold 
opinion    existed    concerning    spiritual    substances.     Some 
said  that  all  proceeded  from  God  in  a  certain  equality,  as 
Origen  said  (Peri  Archon.  i.);  or  at  least  many  of  them,  as 
some  others  thought.      Others  said  that  all  spiritual  sub- 
stances proceeded  from  God  in  a  certain  degree  and  order; 
and  Dionysius  [CcbI.  Hier.  x.)  seems  to  have  thought  so, 
when  he  said  that  among  spiritual  substances  there  are  the 
first,  the  middle,  and  the  last;  even  in  one  order  of  angels. 
Now  according  to  the  first  opinion,  it  must  be  said  that 
there  are  many  seviternities,  as  there  are  many  aeviternal 
things  of  first  degree.     But  according  to  the  second  opinion, 
it  would  be  necessary  to  say  that  there  is  one  aeviternity 
only;  because  since  each  thing  is  measured  by  the  most 


g.  lo.  Art.  6.     THE  ''  SUMMA  THEOLOGICA  "  no 

simple  element  of  its  genus,  it  must  be  that  the  existence 
of  all  seviternal  things  should  be  measured  by  the  existence 
of  the  first  ^viternal  thing,  which  is  all  the  more  simple 
the  nearer  it  is  to  the  first.  Wherefore  because  the  second 
opinion  is  the  truer,  as  will  be  shown  later  (Q.  XLVII.  A.  2) ; 
we  concede  at  present  that  there  is  only  one  seviternity. 

Reply  Obj.  i.  iEviternity  is  sometimes  taken  for  age, 
that  is,  a  space  of  a  thing's  duration;  and  thus  we  say  many 
aeviternities  when  we  mean  ages. 

Reply  Obj.  2.  Although  the  heavenly  bodies  and  spiritual 
things  differ  in  the  genus  of  their  nature,  still  they  agree  in 
having  a  changeless  being,  and  are  thus  measured  by 
seviternity. 

Reply  Obj.  3.  All  temporal  things  did  not  begin  together; 
nevertheless  there  is  one  time  for  all  of  them,  by  reason  of 
the  first  measured  by  time;  and  thus  all  seviternal  things 
have  one  aeviternity  by  reason  of  the  first,  though  all  did 
not  begin  together. 

Reply  Obj.  4.  For  things  to  be  measured  by  one,  it  is  not 
necessary  that  the  one  should  be  the  cause  of  all,  but  that  it 
be  more  simple  than  the  rest. 


QUESTION  XI. 

THE  UNITY  OF  GOD. 

{In  Four  Articles.) 

After  the  foregoing,  we  consider  the  divine  unity;  con- 
cerning which  there  are  four  points  of  inquiry:  (i)  Whether 
one  adds  anything  to  being?  (2)  Whether  one  and  many 
are  opposed  to  each  other  ?  (3)  Whether  God  is  one  ? 
(4)  Whether  He  is  in  the  highest  degree  one  ? 

First  Article, 
whether  one  adds  anything  to  being  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  one  adds  something  to  being. 
For  everything  is  in  a  determinate  genus  by  addition  to 
being,  which  penetrates  all  genera.  But  one  is  in  a  deter- 
minate genus,  for  it  is  the  principle  of  number,  which  is  a 
species  of  quantity .   Therefore  one  adds  something  to  being. 

Obj.  2.  Further,  what  divides  a  thing  common  to  all,  is 
an  addition  to  it.  But  being  is  divided  by  one  and  by 
many.     Therefore  one  is  an  addition  to  being. 

Obj.  3.  Further,  if  one  is  not  an  addition  to  being,  one 
and  being  must  have  the  same  meaning.  But  it  would  be 
nugatory  to  call  being  by  the  name  of  being :  therefore  it 
would  be  equally  so  to  call  being  one.  Now  this  is  false. 
Therefore  one  is  an  addition  to  being. 

On  the  contrary,  Dionysius  says  {Div.  Nom.  V,  ult.) :  Nothing 
which  exists  is  not  in  some  way  one,  which  would  be  false  if 
one  were  an  addition  to  being,  in  the  sense  of  limiting  it. 
Therefore  one  is  not  an  addition  to  being. 

I  answer  that,  One  does  not  add  any  reality  to  beiitg  ;  but 

III 


Q.  II.  Art.  i     THE  "  SUMMA  THEOLOGICA  "  112 

is  only  a  negation  of  division:  for  one  means  undivided 
being.  This  is  the  very  reason  why  one  is  the  same  as  being. 
Now  every  being  is  either  simple,  or  compound.  But  what 
is  simple,  is  undivided,  both  actually  and  potentially. 
Whereas  what  is  compound,  has  not  being  whilst  its 
parts  are  divided,  but  after  they  make  up  and  compose  it. 
Hence  it  is  manifest  that  the  being  of  anything  consists  in 
undivision ;  and  hence  it  is  that  everything  guards  its  unity 
as  it  guards  its  being. 

Reply  Obj.  i.  Some,   thinking  that  the  one  convertible 
with  being  is  the  same  as  the  one  which  is  the  principle  of 
number,  were  divided  into  contrary  opinions.     Pythagoras 
and  Plato,  seeing  that  the  one  convertible  with  being  did 
not  add  any  reality  to  being,  but  signified  the  substance  of 
being  as  undivided,  thought  that  the  same  applied  to  the 
one  which  is  the  principle  of  number.     And  because  number 
is  composed  of  unities,  they  thought  that  numbers  were  the 
substances  of  all  things.     Avicenna,  however,  on  the  con- 
trary, considering  that  one  which  is  the  principle  of  number, 
added  a  reality  to  the  substance  of  being  (otherwise  number 
made  of  unities  would  not  be  a  species  of  quantity),  thought 
that  the  one  convertible  with  being  added  a  reality  to  the 
substance  of  beings;  as  white  to  man.     This,  however,  is 
manifestly    false,  inasmuch    as  each  thing   is  one  by  its 
substance.     For  if  a  thing  were  one  by  anything  else  but 
by  its  substance,  since  this  again  would  be  one,  supposing 
it  were  again  one  by  another  thing,  we  should  be  driven  on 
to  infinity.     Hence  we  must  adhere  to  the  former  statement ; 
therefore  we  must  say  that  the  one  which  is  convertible 
with  being,  does  not  add  a  reality  to  being;  but  that  the 
one  which  is  the  principle  of  number,  does  add  a  reality  to 
being,  belonging  to  the  genus  of  quantity. 

Reply  Obj.  2.  There  is  nothing  to  prevent  a  thing  which 
in  one  way  is  divided,  from  being  another  way  undivided;  as 
what  is  divided  in  number,  may  be  undivided  in  species; 
thus  it  may  be  that  a  thing  is  in  one  way  one,  and  in  another 
way  many.  Still,  if  it  is  absolutely  undivided,  either  because 
it  is  so  according  to  what  belongs  to  its  essence,  though  it 


113  THE  UNITY  OF  GOD  Q.  n.  Art.  2 

may  be  divided  as  regards  what  is  outside  its  essence,  as 
what  is  one  in  subject  may  have  many  accidents;  or  because 
it  is  undivided  actually,  and  divided  potentially,  as  what  is 
one  in  the  whole,  and  is  many  in  parts;  in  such  a  case  a 
thing  will  be  one  absolutely,  and  many  accidentally.  On 
the  other  hand,  if  it  be  undivided  accidentally,  and  divided 
absolutely,  as  if  it  were  divided  in  essence  and  undivided  in 
idea  or  in  principle  or  cause,  it  will  be  many  absolutely,  and 
one  accidentally;  as  what  are  many  in  number,  and  one  in 
species,  or  one  in  principle.  Hence  in  that  way,  being  is 
divided  by  one,  and  by  many;  as  it  were  by  one  absolutely, 
and  by  many  accidentally.  For  multitude  itself  would 
not  be  contained  under  heing,  unless  it  were  in  some  way 
contained  under  one.  Thus  Dionysius  says  {Div.  Nom.,  cap. 
nit.)  that  there  is  no  kind  of  multitude  that  is  not  in  a  way  one. 
But  what  are  many  in  their  parts,  are  one  in  their  whole;  and 
what  are  many  in  accidents,  are  one  in  subject;  and  what  are 
many  in  number,  are  one  in  species;  and  what  are  many  in 
species,  are  one  in  genus;  and  what  are  many  in  processions, 
are  one  in  principle. 

Reply  Obj.  3.  It  does  not  follow  that  it  is  nugatory  to 
say  being  is  one  ;  forasmuch  as  one  adds  an  idea  to  being. 


Second  Article, 
whether  one  and  many  are  opposed  to  each  other  ? 

We  proceed  thus  to  the  Second  Article: — 

Objection  1.  It  seems  that  one  and  many  are  not  mutually 
opposed.  For  no  opposite  thing  is  predicated  of  its  oppo- 
site. But  every  multitude  is  in  a  certain  way  one,  as  appears 
from  the  preceding  article.  Therefore  one  is  not  opposed 
to  multitude, 

Obj.  2.  Further,  no  opposite  thing  is  constituted  by  its 
opposite.  But  multitude  is  constituted  by  one.  Therefore 
it  is  not  opposed  to  multitude. 

Obj.  3.  Further,  one  is  opposed  to  one.  But  the  idea  oifew 
is  opposed  to  many.     Therefore  one  is  not  opposed  to  many, 

Obj.  4.  Further,  if  one  is  opposed  to  multitude,  it  is 
I.  8 


Q.  II.  Art.  2.    THE  "  SUMMA  THEOLOGICA  "  E14 

opposed  as  the  undivided  is  to  the  divided;  and  is  thus 
opposed  to  it  as  privation  is  to  habit.  But  this  appears  to 
be  incongruous;  because  it  would  follow  that  one  comes 
after  multitude,  and  is  defined  by  it;  whereas,  on  the  con- 
trary, multitude  is  defined  by  one.  Hence  there  would 
be  a  vicious  circle  in  the  definition;  which  is  inadmissible. 
Therefore  one  and  many  are  not  opposed. 

On  the  contrary,  Things  which  are  opposed  in  idea,  are 
themselves  opposed  to  each  other.  But  the  idea  of  one 
consists  in  indivisibility;  and  the  idea  of  multitude  contains 
division.   Therefore  one  and  many  are  opposed  to  each  other. 

/  answer  that,  One  is  opposed  to  many,  but  in  various 
ways.  The  one  which  is  the  principle  of  number,  is 
opposed  to  multitude  which  is  number,  as  the  measure  is  to 
the  thing  measured.  For  one  implies  the  idea  of  a  primary 
measure;  and  number  is  multitude  measured  by  one,  as  is 
clear  from  Metaph.  x.  But  the  one  which  is  convertible 
with  being  is  opposed  to  multitude  by  way  of  privation; 
as  the  undivided  is  to  the  thing  divided. 

Reply  Ohj.  i.  No  privation  entirely  takes  away  the  being 
of  a  thing,  inasmuch  as  privation  means  negation  in  the 
subject,  according  to  the  Philosopher  (Categor.  viii.) .  Never- 
theless every  privation  takes  away  some  being;  and  so  in 
being,  by  reason  of  its  universality,  the  privation  of  being  has 
its  foundation  in  being ;  which  is  not  the  case  in  privations 
of  special  forms,  as  of  sight,  or  of  whiteness,  and  the  like. 
And  what  applies  to  being  applies  also  to  one  and  to  good, 
which  are  convertible  with  being,  for  the  privation  of  good 
is  founded  in  some  good;  likewise  the  removal  of  unity  is 
founded  in  some  one  thing.  Hence  it  happens  that  multi- 
tude is  some  one  thing ;  and  evil  is  some  good  thing,  and  non- 
being  is  some  kind  of  being.  Nevertheless,  opposite  is  not 
predicated  of  opposite;  forasmuch  as  one  is  absolute,  and 
the  other  is  relative;  for  what  is  relative  being  (as  a  po- 
tentiality) is  non-being  absolutely,  i.e.,  actually;  or  what  is 
absolute  being  in  the  genus  of  substance,  is  non-being  rela- 
tively as  regards  some  accidental  being.  In  the  same  way, 
what  is  relatively  good  is  absolutely  bad,  or  vice  versa  ; 


115  'iHE  UNITY  OF  GOD  Q.  n.  Art.  2 

likewise,  what  is  absolutely  one  is  relatively  many,  and 
vice  versa. 

Reply  Ohj.  2.  A  whole  is  twofold.  In  one  sense  it  is 
homogeneous,  composed  of  like  parts;  in  another  sense  it  is 
heterogeneous,  composed  of  dissimilar  parts.  Now  in  every 
homogeneous  whole,  the  whole  is  made  up  of  parts  having 
the  form  of  the  whole ;  as,  for  instance,  every  part  of  water 
is  water ;  and  such  is  the  constitution  of  a  continuous  thing 
made  up  of  its  parts.  In  every  heterogeneous  whole,  how- 
ever, every  part  is  wanting  in  the  form  belonging  to  the 
whole ;  as,  for  instance,  no  part  of  a  house  is  a  house,  nor  is 
any  part  of  man  a  man.  Now  multitude  is  such  a  kind 
of  whole.  Therefore  inasmuch  as  its  part  has  not  the  form 
of  the  multitude,  the  latter  is  composed  of  unities,  as  a 
house  is  composed  of  not  houses;  not,  indeed,  as  if  unities 
constituted  multitude  so  far  as  they  are  undivided,  in  which 
way  they  are  opposed  to  multitude;  but  so  far  as  they 
have  being,  as  also  the  parts  of  a  house  make  up  the  house 
by  the  fact  that  they  are  beings,  not  by  the  fact  that  they 
are  not  houses. 

Reply  Ohj.  3.  Many  is  taken  in  two  ways:  absolutely, 
and  in  that  sense  it  is  opposed  to  one  :  in  another  way  as 
importing  some  kind  of  excess,  in  which  sense  it  is  opposed 
to  fev!) :  hence  in  the  first  sense  two  are  many ;  but  not  in 
the  second  sense. 

Reply  Ohj.  4.  One  is  opposed  to  many  privatively, 
inasmuch  as  the  idea  of  many  involves  division.  Hence 
division  must  be  prior  to  unity,  not  absolutely  in  itself, 
but  according  to  our  way  of  apprehension.  For  we  appre- 
hend simple  things  by  compound  things;  and  hence  we 
define  a  point  to  be,  what  has  no  part,  or  the  beginning 
of  a  line.  Multitude  also,  in  idea,  follows  on  one  ;  because 
we  do  not  understand  divided  things  to  convey  the  idea 
of  multitude  except  by  the  fact  that  we  attribute  unity  to 
every  part.  Hence  one  is  placed  in  the  definition  of  multi- 
tude ;  but  multitude  is  not  placed  in  the  definition  of  one. 
But  division  comes  to  be  understood  from  the  very  negation 
of  being:  so  what  first  comes  to  the  mind  is  being;  secondly. 


Q.  II.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  116 

that  this  being  is  not  that  being,  and  thus  we  apprehend 
division  as  a  consequence ;  thirdly,  comes  the  notion  of  one ; 
fourthly,  the  notion  of  multitude. 


Third  Articlb. 
whether  god  is  one  ? 

We  proceed  thus  to  the  Third  A  rticle  : — 

Objection  i.  It  seems  that  God  is  not  one.  For  it 
is  written,  For  there  he  many  gods  and  many  lords  (i  Cor. 
viii.  5). 

Ohj.  2.  Further,  one,  as  the  principle  of  number,  cannot 
be  predicated  of  God,  since  quantity  is  not  predicated  of 
God;  likewise,  neither  can  one  which  is  convertible  with 
being  be  predicated  of  God,  because  it  imports  privation, 
and  every  privation  is  an  imperfection,  which  cannot  apply 
to  God.     Therefore  God  is  not  one. 

On  the  contrary,  It  is  written.  Hear,  0  Israel,  the  Lord  our 
God  is  one  Lord  (Deut.  vi.  4). 

/  answer  that.  It  can  be  shown  from  three  sources  that  God 
is  one.  First  from  His  simplicity.  For  it  is  manifest  that 
the  reason  why  any  singular  thing  is  this  particular  thing  is 
because  it  cannot  be  communicated  to  many:  since  that 
whereby  Socrates  is  a  man,  can  be  communicated  to  many ; 
whereas,  what  makes  him  this  particular  man,  is  only  com- 
municable to  one.  Therefore,  if  Socrates  were  a  man  by 
what  makes  him  to  be  this  particular  man,  as  there  cannot 
be  many  Socrates,  so  there  could  not  in  that  way  be  many 
men.  Now  this  belongs  to  God  alone;  for  God  Himself 
is  His  own  nature,  as  was  shown  above  (Q.  III.  A.  3).  There- 
fore, in  the  very  same  way  God  is  God,  and  He  is  this 
God.  Impossible  is  it  therefore  that  many  Gods  should 
exist. 

Secondly,  this  is  proved  from  the  infinity  of  His  perfection. 
For  it  was  shown  above  (Q.  IV.  A.  2)  that  God  comprehends 
in  Himself  the  whole  perfection  of  being.  If  then  many  gods 
existed,  they  would  necessarily  differ  from  each  other. 
Sorr.ething  therefore  would  belong  to  one,  which  did  not 


117  THE  UNITY  OF  GOD  Q.  ii.  Art.  3 

belong  to  another.  And  if  this  were  a  privation,  one  of 
them  would  not  be  absolutely  perfect;  but  if  a  perfection, 
one  of  them  would  be  without  it.  So  it  is  impossible  for 
many  gods  to  exist.  Hence  also  the  ancient  philosophers, 
constrained  as  it  were  by  truth,  when  they  asserted  an 
infinite  principle,  asserted  likewise  that  there  was  only  one 
such  principle. 

Thirdly,  this  is  shown  from  the  unity  of  the  world.  For  all 
things  that  exist  are  seen  to  be  ordered  to  each  other  since 
some  serve  others.  But  things  that  are  diverse  do  not 
harmonize  in  the  same  order,  unless  they  are  ordered 
thereto  by  one.  For  many  are  reduced  into  one  order  by 
one  better  than  by  many :  because  one  is  the  per  se  cause  of 
one,  and  many  are  only  the  accidental  cause  of  one,  inas- 
much as  they  are  in  some  way  one.  Since  therefore  what 
is  first  is  most  perfect,  and  is  so  per  se  and  not  accidentally, 
it  must  be  that  the  first  which  reduces  all  into  one  order 
should  be  only  one.     And  this  one  is  God. 

Reply  Ohj.  i.  Gods  are  called  many  by  the  error  of  some 
who  worshipped  many  deities,  thinking  as  they  did  that  the 
planets  and  other  stars  were  gods,  and  also  the  separate 
parts  of  the  world.  Hence  the  Apostle  adds:  Our  God  is 
one,  etc. 

Reply  Ohj.  2.  One  which  is  the  principle  of  number  is 
not  predicated  of  God,  but  only  of  material  things.  For 
one  the  principle  of  number  belongs  to  the  genus  of  mathe- 
matics, which  are  material  in  being,  and  abstracted  from 
matter  only  in  idea .  But  one  which  is  convertible  with  being 
is  a  metaphysical  entity,  and  does  not  depend  on  matter, 
in  its  being.  And  although  in  God  there  is  no  privation, 
still,  according  to  the  mode  of  our  apprehension.  He  is 
known  to  us  by  way  only  of  privation  and  remotion.  Thus 
there  is  no  reason  why  a  certain  kind  of  privation  should 
not  be  predicated  of  God;  for  instance,  that  He  is  incor- 
poreal, and  infinite;  and  in  the  same  way  it  is  said  of  God 
that  He  is  one.

Fourth  Article, 
whether  god  is  supremely  one  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  God  is  not  supremely  one. 
For  one  is  so  called  from  the  privation  of  division.  But 
privation  cannot  be  greater  or  less.  Therefore  God  is  not 
more  one  than  other  things  which  are  called  one. 

Ohj.  2.  Further,  nothing  seems  to  be  more  indivisible 
than  what  is  actually  and  potentially  indivisible;  such  as 
a  point,  and  unity.  But  a  thing  is  said  to  be  more  one 
according  as  it  is  indivisible.  Therefore  God  is  not  more 
one  than  unity  is  one  and  a  point  is  one. 

Ohj.  3.  Further,  what  is  essentially  good  is  supremely 
good.  Therefore,  what  is  essentially  one  is  supremely 
one.  But  every  being  is  essentially  one,  as  the  Philosopher 
says  {Metaph.  iv.).  Therefore  every  being  is  supremely 
one  ;  and  therefore  God  is  not  one  more  than  any  other 
being  is  one. 

On  the  contrary,  Bernard  says  (De  Consid.  v.) :  Among  all 
things  called  one,  the  unity  of  the  Divine  Trinity  holds  the  first 
place. 

I  answer  that,  Since  one  is  an  undivided  being,  if  anything 
is  supremely  one  it  must  be  supremely  being,  and  supremely 
undivided.  Now  both  of  these  belong  to  God.  For  He  is 
supremely  being,  inasmuch  as  His  being  is  not  determined 
by  any  nature  to  which  it  is  adjoined ;  since  He  is  being  itself, 
subsistent,  absolutely  undetermined.  But  He  is  supremely 
undivided  inasmuch  as  He  is  divided  neither  actually,  nor 
potentially,  by  any  mode  of  division ;  since  He  is  altogether 
simple,  as  was  shown  above  (Q.  HI.  A.  7).  Hence  it  is 
manifest  that  God  is  one  in  the  supreme  degree. 

Reply  Ohj.  i.  Although  privation  considered  in  itself  is  not 
susceptive  of  more  or  less,  still  according  as  its  opposite  is 
subject  to  more  and  less,  privation  also  can  be  considered 
itself  in  the  light  of  more  and  less.  Therefore,  according 
as  a  thing  is  more  divided,  or  is  divisible,  either  less  or  not 


119  THE  UNITY  OF  GOD  Q.  n.  Art.  4 

at  all,  in  that  degree  it  is  called  more,  or  less,  or  supremely, 
one. 

Reply  Ohj.  2.  A  point,  and  unity  which  is  the  principle  of 
number,  are  not  supremely  being,  inasmuch  as  they  have 
being  only  in  some  subject.  Hence  neither  of  them  can 
be  supremely  one.  For  as  a  subject  cannot  be  supremely 
one,  because  of  the  difference  within  it  of  accident  and 
subject,  so  neither  can  an  accident. 

Reply  Ohj.  3.  Although  every  being  is  one  by  its  substance, 
still  every  such  substance  is  not  equally  the  cause  of  unity ; 
for  the  substance  of  some  things  is  compound,  and  of  others 
simple. 


QUESTION  XII. 

HOW  GOD  IS  KNOWN  BY  US. 

{In  Thirteen  Articles.) 

As  hitherto  we  have  considered  God  as  He  is  in  Himself, 
we  now  go  on  to  consider  in  what  manner  He  is  in  the 
knowledge  of  creatures;  concerning  which  there  are 
thirteen  points  of  inquiry,  (i)  Whether  any  created 
intellect  can  see  the  essence  of  God  ?  (2)  Whether  the 
essence  of  God  is  seen  by  the  intellect  through  any 
created  image  ?  (3)  Whether  the  essence  of  God  can  be 
seen  by  the  corporeal  eye  ?  (4)  Whether  any  created  in- 
tellectual substance  is  sufficient  by  its  own  natural  powers  to 
see  the  essence  of  God  ?  (5)  Whether  the  created  intellect 
needs  any  created  light  in  order  to  see  the  essence  of  God  ? 
(6)  Whether  of  those  who  see  God,  one  sees  Him  more 
perfectly  than  another  ?  (7)  Whether  any  created  intellect 
can  comprehend  the  essence  of  God  ?  (8)  Whether  the 
created  intellect  seeing  the  essence  of  God,  knows  all  things 
in  it  ?  (9)  Whether  what  is  there  known  is  known  by  any 
similitudes  ?  (10)  Whether  the  created  intellect  knows 
all  at  once  what  it  sees  in  God  ?  (11)  Whether  in  the  state 
of  this  life  any  man  can  see  the  essence  of  God  ?  (12) 
Whether  by  natural  reason  we  can  know  God  in  this  life  ? 
(13)  Whether  there  is  in  this  life  any  knowledge  of  God 
through  grace  above  the  knowledge  of  natural  reason  ? 

First  Article, 
whether  any  created  intellect  can  see  the  essence 

OF   GOD  ? 

We  proceed  thus  to  the  First  Article  : — 
Objection  i.  It  seems  that  no  created  intellect  can  see  the 
essence  of  God.     For  Chrysostom  [Horn.  xiv.  in  Joan)  com- 

120 


121  HOW  GOD  IS  KNOWN  BY  US      Q.  12.  Art.  i 

meriting  on  John  i.  18,  No  man  hath  seen  God  at  any  time, 
says:  Not  prophets  only,  huf neither  angels  nor  archangels  have 
seen  God.  For  how  can  a  creature  see  what  is  increatable  ? 
Dionysius  also  says  (Dii),  Nom.  i.),  speaking  of  God:  Neither 
is  there  sense,  nor  image,  nor  opinion,  nor  reason,  nor  know- 
ledge of  Him. 

Ohj.  2.  Further,  everything  infinite,  as  such,  is  unknown. 
But  God  is  infinite,  as  was  shown  above  (Q.  VII.  A.  i). 
Therefore  in  Himself  He  is  unknown. 

Ohj.  3.  Further,  the  created  intellect  knows  only  existing 
things.  For  what  falls  first  under  the  apprehension  of  the 
intellect  is  being.  Now  God  is  not  something  existing;  but 
He  is  rather  super-existence,  as  Dionysius  says  {Div.  Nom. 
iv.) .    Therefore  God  is  not  intelligible ;  but  above  all  intellect. 

Ohj.  4.  Further,  there  must  be  some  proportion  between 
the  knower  and  the  known,  since  the  known  is  the  perfection 
of  the  knower.  But  no  proportion  exists  between  the 
created  intellect  and  God;  for  there  is  an  infinite  distance 
between  them.  Therefore  the  created  intellect  cannot  see 
the  essence  of  God. 

On  the  contrary,  It  is  written:  We  shall  see  Him  as  He 
is  (i  Johniii.  2). 

/  answer  that.  Since  everything  is  knowable  according  as 
it  is  actual,  God,  Who  is  pure  act  without  any  admixture 
of  potentiality,  is  in  Himself  supremely  knowable.  But 
what  is  supremely  knowable  in  itself,  may  not  be  knowable 
to  a  particular  intellect,  on  account  of  the  excess  of  the  in- 
telligible object  above  the  intellect;  as,  for  example,  the 
sun,  which  is  supremely  visible,  cannot  be  seen  by  the  bat 
by  reason  of  its  excess  of  light. 

Therefore  some  who  considered  this,  held  that  no  created 
intellect  can  see  the  essence  of  God.  This  opinion,  how- 
ever, is  not  tenable.  For  as  the  ultimate  beatitude  of  man 
consists  in  the  use  of  his  highest  function,  which  is  the  opera- 
tion of  the  intellect ;  if  we  suppose  that  the  created  intellect 
could  never  see  God,  it  would  either  never  attain  to  beatitude, 
or  its  beatitude  would  consist  in  something  else  beside  God ; 
which  is  opposed  to  faith.      For  the  ultimate    perfection 


g.  12.  Art.  I    THE  "  SUMMA  THEOLOGICA  "  122 

of  the  rational  creature  is  to  be  found  in  that  which  is  the 
principle  of  its  being ;  since  a  thing  is  perfect  so  far  as  it  attains 
to  its  principle.  Further  the  same  opinion  is  also  against 
reason.  For  there  resides  in  every  man  a  natural  desire 
to  know  the  cause  of  any  effect  which  he  sees ;  and  thence 
arises  wonder  in  men.  But  if  the  intellect  of  the  rational 
creature  could  not  reach  so  far  as  to  the  first  cause  of  things, 
the  natural  desire  would  remain  void. 

Hence  it  must  be  absolutely  granted  that  the  blessed 
see  the  essence  of  God. 

Reply  Obj.  i.  Both  of  these  authorities  speak  of  the 
vision  of  comprehension.  Hence  Dionysius  premises  im- 
mediately before  the  words  cited,  He  is  universally  to 
all  incomprehensible,  etc.  Chrysostom,  likewise  after  the 
words  quoted,  says :  He  says  this  of  the  most  certain  vision  of 
the  Father,  which  is  such  a  perfect  consideration  and  com- 
prehension as  the  Father  has  of  the  Son. 

Reply  Obj.  2.  The  infinity  of  matter  not  made  perfect  by 
form,  is  unknown  in  itself,  because  all  knowledge  comes  by 
the  form;  whereas  the  infinity  of  the  form  not  limited  by 
matter,  is  in  itself  supremely  known.  God  is  Infinite  in  this 
way,  and  not  in  the  first  way:  as  appears  from  what  was 
said  above  (Q.  VH.  A.  i). 

Reply  Obj.  3.  God  is  not  said  to  be  not  existing  as  if  He 
did  not  exist  at  all,  but  because  He  exists  above  all  that 
exists;  inasmuch  as  He  is  His  own  existence.  Hence  it 
does  not  follow  that  He  cannot  be  known  at  all,  but  that 
He  exceeds  every  kind  of  knowledge;  which  means  that  He 
is  not  comprehended. 

Reply  Obj.  4.  Proportion  is  twofold.  In  one  sense  it 
means  a  certain  relation  of  one  quantity  to  another,  according 
as  double,  treble,  and  equal  are  species  of  proportion.  In 
another  sense  every  relation  of  one  thing  to  another  is  called 
proportion.  And  in  this  sense  there  can  be  a  proportion 
of  the  creature  to  God,  inasmuch  as  it  is  related  to  Him  as 
the  effect  to  its  cause,  and  as  potentiality  to  its  act ;  and  in 
this  way  the  created  intellect  can  be  proportioned  to  know 
God.

Second  Article. 

whether  the  essence  of  god  is  seen  by  the  created 
intellect  through  an  image  ? 

We  proceed  thus  to  the  Second  Article : — 

Objection  i.  It  seems  that  the  essence  of  God  is  seen 
through  an  image  by  the  created  intellect.  For  it  is 
written:  We  know  that  when  He  shall  appear,  we  shall  he  like 
to  Him,  and  (Vulg.,  because)  we  shall  see  Him  as  He  is 
(i  John  iii.  2). 

Obj.  2.  Further,  Augustine  says  (De  Trin,  v.):  When 
we  know  God,  some  likeness  of  God  is  made  in  us. 

Obj.  3.  Further,  the  intellect  in  act  is  the  actual  in- 
telligible; as  sense  in  act  is  the  actual  sensible.  But  this 
comes  about  inasmuch  as  sense  is  informed  with  the  likeness 
of  the  sensible  object,  and  the  intellect  with  the  likeness  of  the 
thing  understood.  Therefore,  if  God  is  seen  by  the  created  in- 
tellect in  act,  it  must  be  that  He  is  seen  by  some  similitude. 

On  the  contrary,  Augustine  says  {De  Trin.  xv.),  that  when 
the  Apostle  says,  *  We  see  through  a  glass  and  in  an  enigma,'* 
by  the  terms  *  glass  '  and  '  enigma  '  certain  similitudes  are 
signified  by  him,  which  are  accommodated  to  the  vision  of  God. 
But  to  see  the  essence  of  God  is  not  an  enigmatic  nor  a  specu- 
lative vision,  but  is,  on  the  contrary,  of  an  opposite  kind. 
Therefore  the  divine  essence  is  not  seen  through  a  similitude. 

/  answer  that,  Two  things  are  required  both  for  sensible 
and  for  intellectual  vision — viz.,  power  of  sight,  and  union  of 
the  thing  seen  with  the  sight.  For  vision  is  made  actual  only 
when  the  thing  seen  is  in  a  certain  way  in  the  seer.  Now  in 
corporeal  things  it  is  clear  that  the  thing  seen  cannot  be 
by  its  essence  in  the  seer,  but  only  by  its  likeness;  as  the 
similitude  of  a  stone  is  in  the  eye,  whereby  the  vision  is 
made  actual;  whereas  the  substance  of  the  stone  is  not  there. 
But  if  the  principle  of  the  visual  power  and  the  thing  seen 
were  one  and  the  same  thing,  it  would  necessarily  follow 
that  the  seer  would  receive  both  the  visual  power  and  the 
form  whereby  it  sees,  from  that  one  same  thing. 
*  Douay, — in  a  dark  manner. 


Q.  12.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  124 

Now  it  is  manifest  both  that  God  is  the  author  of  the  in- 
tellectual power,  and  that  He  can  be  seen  by  the  intellect. 
And  since  the  intellective  power  of  the  creature  is  not  the 
essence  of  God,  it  follows  that  it  is  some  kind  of  participated 
likeness  of  Him  who  is  the  first  intellect.  Hence  also  the 
intellectual  power  of  the  creature  is  called  an  intelligible 
light,  as  it  were,  derived  from  the  first  light,  whether  this  be 
understood  of  the  natural  power,  or  of  some  perfection 
superadded  of  grace  or  of  glory.  Therefore,  in  order  to  see 
God,  there  must  be  some  similitude  of  God  on  the  part  of  the 
visual  faculty,  whereby  the  intellect  is  made  capable  of 
seeing  God.  But  on  the  part  of  the  object  seen,  which  must 
necessarily  be  united  to  the  seer,  the  essence  of  God  cannot  be 
seen  by  any  created  similitude.  First,  because,  as  Dionysius 
says  {Div.  Nom.  i.),  by  the  similitudes  of  the  inferior  order 
of  things,  the  superior  can  in  no  way  he  known  ;  as  by  the  like- 
ness of  a  body  the  essence  of  an  incorporeal  thing  cannot 
be  known.  Much  less  therefore  can  the  essence  of  God  be 
seen  by  any  created  likeness  whatever.  Secondly,  because 
the  essence  of  God  is  His  own  very  existence,  as  was  shown 
above  (Q.  III.  A.  4),  which  cannot  be  said  of  any  created  form ; 
and  so  no  created  form  can  be  the  similitude  representing 
the  essence  of  God  to  the  seer.  Thirdly,  because  the  divine 
essence  is  uncircumscribed,  and  contains  in  itself  super- 
eminently whatever  can  be  signified  or  understood  by  the 
created  intellect.  Now  this  cannot  in  any  way  be  repre- 
sented by  any  created  likeness;  for  every  created  form  is 
determined  according  to  some  aspect  of  wisdom,  or  of  power^ 
or  of  being  itself,  or  of  some  like  thing.  Hence  to  say  that 
God  is  seen  by  some  similitude,  is  to  say  that  the  divine 
essence  is  not  seen  at  all;  which  is  false. 

Therefore  it  must  be  said  that  to  see  the  essence  of  God 
there  is  required  some  similitude  in  the  visual  faculty,  namely, 
the  light  of  glory  strengthening  the  intellect  to  see  God,  which 
is  spoken  of  in  the  Psalm  (xxxv.  10),  In  Thy  light  we  shall 
see  light.  The  essence  of  God,  however,  cannot  be  seen  by 
any  created  similitude  representing  the  divine  essence  itself 
as  it  really  is.

Third  Article. 

whether  the  essence  of  god  can  be  seen  with  the 

bodily  eye  ? 

We  proceed  thus  to  the  Third  Article : — ■ 

Objection  1.  It  seems  that  the  essence  of  God  can  be  seen 
by  the  corporeal  eye.  For  it  is  written  (Job  xix.  26):  In 
my  flesh  I  shall  see  .  .  .  God,  and  (ibid.  xlii.  5),  With  the 
hearing  of  the  ear  I  have  heard  Thee,  but  now  my  eye  seeth  Thee. 

Obj.  2.  Further,  Augustine  says  [De  Civ.  Dei  xxix.  29): 
Those  eyes  [namely  of  the  glorified]  will  therefore  have  a 
greater  power  of  sight,  not  so  much  to  see  more  keenly,  as  some 
report  of  the  sight  of  serpents  or  of  eagles  {for  whatever  acute- 
ness  of  vision  is  possessed  by  these  creatures,  they  can  see  only 
corporeal  things)  but  to  see  even  incorporeal  things.  Now 
whoever  can  see  incorporeal  things,  can  be  raised  up  to 
see  God.     Therefore  the  glorified  eye  can  see  God. 

Obj.  3.  Further,  God  can  be  seen  by  man  through  a  vision 
of  the  imagination.  For  it  is  written:  /  saw  the  Lord  sitting 
upon  a  throne,  etc.  (Isa.  vi.  i).  But  an  imaginary  vision 
originates  from  sense ;  for  the  imagination  is  moved  by  sense 
to  act.     Therefore  God  can  be  seen  by  a  vision  of  sense. 

On  the,  contrary,  Augustine  says  {De  Vid.  Deum,  Ep. 
cxlvii) :  No  one  has  ever  seen  God  either  in  this  life,  as  He  is, 
nor  in  the  angelic  life,  as  visible  things  are  seen  by  corporeal 
vision. 


Q.  12.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  126 

7  answer  that,  It  is  impossible  for  God  to  be  seen  by  the 
sense  of  sight,  or  by  any  other  sense,  or  faculty  of  the  sensi- 
tive power.  For  every  such  kind  of  power  is  the  act  of  a 
corporeal  organ,  as  will  be  shown  later  (Q.  LXXVIIL). 
Now  act  is  proportional  to  the  nature  which  possesses  it. 
Hence  no  power  of  that  kind  can  go  beyond  corporeal  things. 
For  God  is  incorporeal,  as  was  shown  above  (Q.  IH.  A.  i). 
Hence  He  cannot  be  seen  by  the  sense  or  the  imagination, 
but  only  by  the  intellect. 

Reply  Obj.  i.  The  words.  In  my  flesh  I  shall  see  God  my 
Saviour,  do  not  mean  that  God  will  be  seen  with  the  eye  of 
flesh,  but  that  man  existing  in  the  flesh  after  the  resurrection 
will  see  God.  Likewise  the  words.  Now  my  eye  seeth  Thee, 
are  to  be  understood  of  the  mind's  eye,  as  the  Apostle 
says:  May  He  give  unto  you  the  spirit  of  wisdom  .  .  .  in 
the  knowledge  of  Him,  that  the  eyes  of  your  heart  may  be 
enlightened  (Eph.  i.  17,  18). 

Reply  Obj.  2.  Augustine  speaks  as  one  inquiring,  and 
conditionally.  This  appears  from  what  he  says  previously: 
Therefore  they  will  have  an  altogether  different  power  [viz., 
the  glorified  eyes],  if  they  shall  see  that  incorporeal  nature  ; 
and  afterwards  he  explains  this,  saying:  It  is  very  credible, 
that  we  shall  so  see  the  mundane  bodies  of  the  new  heaven  and 
the  new  earth,  as  to  see  most  clearly  God  everywhere  present, 
governing  all  corporeal  things,  not  as  we  now  see  the  invisible 
things  of  God  as  understood  by  what  is  made  ;  but  as  when 
we  see  men  among  whom  we  live,  living  and  exercising  the 
functions  of  human  life,  we  do  not  believe  they  live,  but  see  it. 
Hence  it  is  evident  how  the  glorified  eyes  will  see  God,  as 
now  our  eyes  see  the  life  of  another.  But  life  is  not  seen  with 
the  corporeal  eye,  as  a  thing  in  itself  visible,  but  as  the 
indirect  object  of  the  sense;  which  indeed  is  not  known  by 
sense,  but  at  once,  together  with  sense,  by  some  other 
cognitive  power.  But  that  the  divine  presence  is  known 
by  the  intellect  immediately  on  the  sight  of,  and  through, 
corporeal  things,  happens  from  two  causes — viz.,  from  the 
perspicuity  of  the  intellect,  and  from  the  refulgence  of  the 
divine  glory  infused  into  the  body  after  its  renovation.

Reply  Ohj.  3.  The  essence  of  God  is  not  seen  in  a  vision 
of  the  imagination ;  but  the  imagination  receives  some  form 
representing  God  according  to  some  mode  of  similitude; 
as  in  divine  Scripture  divine  things  are  metaphorically 
described  by  means  of  sensible  things. 


Fourth  Article. 

whether  any  created  intellect  by  its  natural  power  s 
can  see  the  divine  essence  ? 

We  proceed  thus  to  the  Fourth  Article : — 

Objection  i.  It  seems  that  a  created  intellect  can  see  the 
divine  essence  by  its  own  natural  power.  For  Dionysius 
says  [Div.  Nom.  iv.):  An  angel  is  a  pure  mirror,  most  clear, 
receiving,  if  it  is  right  to  say  so,  the  whole  beauty  of  God.  But 
if  a  reflection  is  seen,  the  original  thing  is  seen.  Therefore, 
since  an  angel  by  his  natural  power  understands  himself, 
it  seems  that  by  his  own  natural  power  he  understands  the 
divine  essence. 

Obj.  2.  Further,  what  is  supremely  visible,  is  made  less 
visible  to  us  by  reason  of  our  defective  corporeal  or  intel- 
lectual sight.  But  the  angelic  intellect  has  no  such  defect. 
Therefore,  since  God  is  supremely  intelligible  in  Himself,  it 
seems  that  in  like  manner  He  is  supremely  so  to  an  angel. 
Therefore,  if  he  can  understand  other  intelligible  things  by 
his  own  natural  power,  much  more  can  he  understand  God. 

Obj.  3.  Further,  corporeal  sense  cannot  be  raised  up  to 
understand  incorporeal  substance,  which  is  above  its  nature. 
Therefore  if  to  see  the  essence  of  God  is  above  the  nature  of 
every  created  intellect,  it  follows  that  no  created  intellect  can 
reach  up  to  see  the  essence  of  God  at  all.  But  this  is  false, 
as  appears  from  what  is  said  above  (A.  i).  Therefore  it 
seems  that  it  is  natural  for  a  created  intellect  to  see  the 
divine  essence. 

On  the  contrary,  It  is  written  :  The  grace  of  God  is  life  ever- 
lasting (Rom.  vi.  23).  But  life  everlasting  consists  in  the 
vision  of  the  divine  essence,  according  to  the  words:  This 
is  eternal  life,  that  they  may  know  Thee  the  only  true  God,  etc. 


Q.  12.  Art.  4     THE  "  SUMMA  THEOLOGICA  "  128 

(John  xvii.  3).     Therefore,  to  see  the  essence  of  God  is  pos- 
sible to  the  created  intellect  by  grace,  and  not  by  nature. 

/  answer  that,  It  is  impossible  for  any  created  intellect  to 
see  the  essence  of  God  by  its  own  natural  power.  For  know- 
ledge is  regulated  according  as  the  thing  known  is  in  the 
knower.  But  the  thing  known  is  in  the  knower  according 
to  the  mode  of  the  knower.  Hence  the  knowledge  of  every 
knower  is  ruled  according  to  its  own  nature.  If  therefore 
l^'the  mode  of  anything' s  being  exceeds  the  mode  of  the  knower, 
^^t  must  result  that  the  knowledge  of  that  object  is  above 
the  nature  of  the  knower.  Now  the  mode  of  being  of  things 
is  manifold.  For  some  things  have  being  only  in  this  one 
individual  matter;  as  all  bodies.  But  others  are  subsisting 
natures,  not  residing  in  matter  at  all,  which,  however, 
are  not  their  own  existence,  but  receive  it :  and  these  are  the 
incorporeal  beings,  called  angels.  But  to  God  alone  does  it 
belong  to  be  His  own  subsistent  being.  Therefore,  what 
exists  only  in  individual  matter  we  know  naturally,  foras- 
much as  our  soul,  whereby  we  know,  is  the  form  of  certain 
matter.  Now  our  soul  possesses  two  cognitive  powers; 
one  is  the  act  of  a  corporeal  organ,  which  naturally  knows 
things  existing  in  individual  matter;  hence  sense  knows 
only  the  singular.  But  there  is  another  kind  of  cognitive 
power  in  the  soul,  called  the  intellect ;  and  this  is  not  the  act 
of  any  corporeal  organ.  Wherefore  the  intellect  naturally 
knows  natures  which  exist  only  in  individual  matter;  not 
as  they  are  in  such  individual  matter,  but  according  as  they 
are  abstracted  therefrom  by  the  considering  act  of  the  intel- 
lect ;  hence  it  follows  that  through  the  intellect  we  can  under- 
stand these  objects  as  universal;  and  this  is  beyond  the 
power  of  sense.  Now  the  angelic  intellect  naturally  knows 
natures  that  are  not  in  matter ;  but  this  is  beyond  the  power 
of  the  intellect  of  our  soul  in  the  state  of  its  present  life, 
united  as  it  is  to  the  body.  It  follows  therefore  that  to  know 
self-subsistent  being  is  natural  to  the  divine  intellect  alone; 
Wand  this  is  beyond  the  natural  power  of  any  created  intellect; 
for  no  creature  is  its  own  existence,  forasmuch  as  its  existence 
is    participated.     Therefore    the    created    intellect    cannot 


129  HOW  GOD  IS  KNOWN  BY  US     Q.  12.  Art.  4 

see  the  essence  of  God,  unless  God  by  His  grace  unites 
Himself  to  the  created  intellect,  as  an  object  made  intelligible 
to  it. 

Reply  Obj.  i.  This  mode  of  knowing  God  is  natural  to  an 
angel — namely,  to  know  Him  by  His  own  likeness  reful- 
gent in  the  angel  himself.  But  to  know  God  by  any  created 
similitude  is  not  to  know  the  essence  of  God,  as  was  shov/n 
above  (A.  2).  Hence  it  does  not  follow  that  an  angel  can 
know  the  essence  of  God  by  his  own  power. 

Reply  Obj.  2.  The  angelic  intellect  is  not  defective,  if 
defect  be  taken  to  mean  privation,  as  if  it  were  without 
anything  which  it  ought  to  have.  But  if  defect  be  taken 
negatively,  in  that  sense  every  creature  is  defective,  when 
compared  with  God;  forasmuch  as  it  does  not  possess  the 
excellence  which  is  in  God. 

Reply  Obj.  3.  The  sense  of  sight,  as  being  altogether 
material,  cannot  be  raised  up  to  immateriality.  But  our 
intellect,  or  the  angelic  intellect,  inasmuch  as  it  is  elevated 
above  matter  in  its  own  nature,  can  be  raised  up  above  its 
own  nature  to  a  higher  level  by  grace.  The  proof  is,  that 
sight  cannot  in  any  way  know  abstractedly  what  it  knows 
concretely;  for  in  no  way  can  it  perceive  a  nature  except 
as  this  one  particular  nature;  whereas  our  intellect  is  able 
to  consider  abstractedly  what  it  knows  concretely.  Now 
although  it  knows  things  which  have  a  form  residing  in 
matter,  still  it  resolves  the  composite  into  both  of  these 
elements;  and  it  considers  the  form  separately  by  itself. 
Likewise,  also,  the  intellect  of  an  angel,  although  it  naturally 
knows  the  concrete  in  any  nature,  still  it  is  able  to  separate 
that  existence  by  its  intellect ;  since  it  knows  that  the  thing 
itself  is  one  thing,  and  its  existence  is  another.  Since  there- 
fore the  created  intellect  is  naturally  capable  of  apprehend- 
ing the  concrete  form,  and  the  concrete  being  abstractedly, 
by  way  of  a  kind  of  resolution  of  parts;  it  can  by  grace  be 
raised  up  to  know  separate  subsisting  substance,  and  separate 
subsisting  existence.

Fifth  Article. 

whether  the  created  intellect  needs  any  created 
light  in  order  to  see  the  essence  of  god  ? 

We  proceed  thus  to  the  Fifth  Article  : — 

Objection  i.  It  seems  that  the  created  intellect  does  not 
need  any  created  light  in  order  to  see  the  essence  of  God. 
For  what  is  of  itself  lucid  in  sensible  things  does  not  re- 
quire any  other  light  in  order  to  be  seen.  Therefore  the 
same  applies  to  intelligible  things.  Now  God  is  intelligible 
light .  Therefore  He  is  not  seen  by  the  means  of  any  created 
light. 

Obj.  2.  Further,  if  God  is  seen  through  a  medium,  He  is 
not  seen  in  His  essence.  But  if  seen  by  any  created  light. 
He  is  seen  through  a  medium.  Therefore  He  is  not  seen  in 
His  essence. 

Obj.  3.  Further,  what  is  created  can  be  natural  to  some 
creature.  Therefore,  if  the  essence  of  God  is  seen  through 
any  created  light,  such  a  light  can  be  made  natural  to 
some  other  creature;  and  thus,  that  creature  would  not 
need  any  other  light  to  see  God;  which  is  impossible. 
Therefore  it  is  not  necessary  that  every  creature  should  re- 
quire a  superadded  light  in  order  to  see  the  essence  of  God. 

On  the  contrary,  It  is  written:  In  Thy  light  we  shall  see 
light  (Ps.  XXXV.  10). 

/  answer  that,  Everything  which  is  raised  up  to  what  ex- 
ceeds its  nature,  must  be  prepared  by  some  disposition  above 
its  nature;  as,  for  example,  if  air  is  to  receive  the  form  of 
fire,  it  must  be  prepared  by  some  disposition  for  such  a 
form.  But  when  any  created  intellect  sees  the  essence  of 
God,  the  essence  of  God  itself  becomes  the  intelligible 
form  of  the  intellect.  Hence  it  is  necessary  that  some 
supernatural  disposition  should  be  added  to  the  intellect 
in  order  that  it  may  be  raised  up  to  such  a  great  and  sublime 
height.  Now  since  the  natural  power  of  the  created  intellect 
does  not  avail  to  enable  it  to  see  the  essence  of  God,  as  was 
shown  in  the  preceding  article,  it  is  necessary  that  the 


131  HOW  GOD  IS  KNOWN  BY  US     Q.  12.  Art.  6 

power  of  understanding  should  be  added  by  divine  grace. 
Now  this  increase  of  the  intellectual  powers  is  called  the 
illumination  of  the  intellect,  as  we  also  call  the  intelligible 
object  itself  by  the  name  of  light  or  illumination.  And  this 
is  the  light  spoken  of  in  the  Apocalypse  (xxi.  23) .  The  glory  of 
God  hath  enlightened  it — viz.,  the  society  of  the  blessed  who 
see  God.  By  this  light  the  blessed  are  made  deiform — that 
is,  like  to  God,  according  to  the  saying:  When  He  shall  appear 
we  shall  he  like  to  Him,  and  [Vulg.,  because]  we  shall  see  Him 
as  He  is  (i  John  iii.  2). 

Reply  Obj.  i.  The  created  light  is  necessary  to  see  the 
essence  of  God,  not  in  order  to  make  the  essence  of  God 
intelligible,  which  is  of  itself  intelligible,  but  in  order  to 
enable  the  intellect  to  understand  in  the  same  way  as  a 
habit  makes  a  power  abler  to  act.  Even  so  corporeal 
light  is  necessary  as  regards  external  sight,  inasmuch  as  it 
makes  the  medium  actually  transparent,  and  susceptible 
of  colour. 

Reply  Obj.  2.  This  light  is  required  to  see  the  divine 
essence,  not  as  a  similitude  in  which  God  is  seen,  but  as  a 
perfection  of  the  intellect,  strengthening  it  to  see  God. 
Therefore  it  may  be  said  that  this  light  is  to  be  described 
not  as  a  medium  in  which  God  is  seen,  but  as  one  by  which 
He  is  seen;  and  such  a  medium  does  not  take  away  the 
immediate  vision  of  God. 

Reply  Obj.  3.  The  disposition  to  the  form  of  fire  can  be 
natural  only  to  the  subject  of  that  form.  Hence  the  light  of 
glory  cannot  be  natural  to  a  creature  unless  the  creature  has 
a  divine  nature;  which  is  impossible.  But  by  this  light  the 
rational  creature  is  made  deiform,  as  is  said  in  this  article. 

Sixth  Article. 

whether  of  those  who  see  the  essence  of  god,  one 
sees  more  perfectly  than  another  ? 

We  proceed  thtis  to  the  Sixth  Article: — 
Objection  i.  It  seems  that  of  those  who  see  the  essence 
of  God,  one  does  not  see  more  perfectly  than  another.     For 


Q.  12.  Art.  6    THE  "  SUMMA  THEOLOGICA  "  132 

it  is  written  (i  John  iii.  2) :  We  shall  see  Him  as  He  is.  But 
He  is  only  in  one  way.  Therefore  He  will  be  seen  by  all 
in  one  way  only;  and  therefore  He  will  not  be  seen  more 
perfectly  by  one  and  less  perfectly  by  another. 

Obj.  2.  Further,  as  Augustine  says  {Octog.  Trium  Quest.: 
qu.  xxxii.):  One  person  cannot  see  one  and  the  same  thing 
more  perfectly  than  another.  But  all  who  see  the  essence  of 
God,  understand  the  divine  essence,  for  God  is  seen  by  the 
intellect  and  not  by  sense,  as  was  shown  above  (A.  3). 
Therefore,  of  those  who  see  the  divine  essence,  one  does 
not  see  more  clearly  than  another. 

Ohj.  3.  Further,  That  anything  be  seen  more  perfectly 
than  another  can  happen  in  two  ways :  either  on  the  part 
of  the  visible  object,  or  on  the  part  of  the  visual  power  of 
the  seer.  On  the  part  of  the  object,  it  may  so  happen 
because  the  object  is  received  more  perfectly  in  the  seer, 
that  is,  according  to  the  greater  perfection  of  the  simili- 
tude; but  this  does  not  apply  to  the  present  question,  for 
God  is  present  to  the  intellect  seeing  Him  not  by  way 
of  a  similitude,  but  by  His  essence.  It  follows  then  that 
if  one  sees  Him  more  perfectly  than  another,  this  happens 
according  to  the  difference  of  the  intellectual  power;  thus 
it  follows  too  that  the  one  whose  intellectual  power  is  the 
higher,  will  see  Him  the  more  clearly;  and  this  is  incon- 
gruous; since  equality  with  angels  is  promised  to  men  as 
their  beatitude. 

On  the  contrary,  Eternal  life  consists  in  the  vision  of  God, 
according  to  John  xvii.  3:  This  is  eternal  life,  that  they  may 
know  Thee  the  only  trite  God,  etc.  Therefore,  if  all  saw  the 
essence  of  God  equally  in  eternal  life,  all  would  be  equal; 
the  contrary  to  which  is  declared  by  the  Apostle:  Star 
differs  from  star  in  glory  (i  Cor.  xv.  41). 

/  answer  that,  Of  those  who  see  the  essence  of  God,  one 
sees  Him  more  perfectly  than  another.  This,  indeed,  does 
not  take  place  as  if  one  had  a  more  perfect  similitude  of 
God  than  another,  since  that  vision  will  not  spring  from  any 
similitude;  but  it  will  take  place  because  one  intellect 
will  have  a  greater  power  or  faculty  to  see  God  than  another. 


133  HOW  GOD  IS  KNOWN  BY  US    Q.  12.  Art.  6 

The  faculty  of  seeing  God,  however,  does  not  belong  to 
the  created  intellect  naturally,  but  is  given  to  it  by  the 
light  of  glory,  which  establishes  the  intellect  in  a  kind  of 
deiformity,  as  appears  from  what  is  said  above,  in  the 
preceding  article. 

Hence  the  intellect  which  has  more  of  the  light  of  glory  will 
see  God  the  more  perfectly;  and  he  will  have  a  fuller  par- 
ticipation of  the  light  of  glory  who  has  more  charity; 
because  where  there  is  the  greater  charity,  there  is  the  more 
desire ;  and  desire  in  a  certain  degree  makes  the  one  desiring 
apt  and  prepared  to  receive  the  object  desired.  Hence 
he  who  possesses  the  more  charity,  will  see  God  the  more 
perfectly,  and  will  be  the  more  beatified. 

Reply  Obj.  i.  In  the  words.  We  shall  see  Him  as  He  is, 
the  conjunction  as  determines  the  mode  of  vision  on  the  part 
of  the  object  seen,  so  that  the  meaning  is,  we  shall  see  Him 
to  be  as  He  is,  because  we  shall  see  His  existence,  which  is 
His  essence.  But  it  does  not  determine  the  mode  of  vision 
on  the  part  of  the  one  seeing ;  as  if  the  meaning  was  that  the 
mode  of  seeing  God  will  be  as  perfect  as  is  the  perfect 
mode  of  God's  existence. 

Thus  appears  the  answer  to  the  Second  Objection.  For 
when  it  is  said  that  one  intellect  does  not  understand  one 
and  the  same  thing  better  than  another,  this  would  be  true 
if  referred  to  the  mode  of  the  thing  understood,  for  whoever 
understands  it  otherwise  than  it  really  is,  does  not  truly 
understand  it,  but  not  if  referred  to  the  mode  of  under- 
standing, for  the  understanding  of  one  is  more  perfect  than 
the  understanding  of  another. 

Reply  Obj.  3.  The  diversity  of  seeing  will  not  arise  on  the 
part  of  the  object  seen,  for  the  same  object  will  be  presented 
to  all — viz.,  the  essence  of  God;  nor  will  it  arise  from  the 
diverse  participation  of  the  object  seen  by  different  simili- 
tudes; but  it  will  arise  on  the  part  of  the  diverse  faculty  of 
the  intellect,  not,  indeed,  the  natural  faculty,  but  the  glorified 
faculty.

Seventh  Article. 

whether  those  who  see  the  essence  of  god 
comprehend  him  ? 

We  proceed  thus  to  the  Seventh  Article : — 

Objection  i.  It  seems  that  those  who  see  the  divine  essence, 
comprehend  God.  For  the  Apostle  says  (Phil.  iii.  12) :  But 
I  follow  after,  if  I  may  by  any  means  comprehend  (Douay, 
apprehend).  But  the  Apostle  did  not  follow  in  vain;  for  he 
said  (i  Cor.  ix.  26):  I  ...  so  run,  not  as  at  an  uncertainty. 
Therefore  he  comprehended;  and  in  the  same  way  others 
also,  whom  he  invites  to  do  the  same,  saying:  So  run  that 
you  may  comprehend. 

Obj.  2.  Further,  Augustine  says  {De  Vid.  Deum,  Ep.  cxlvii.) : 
That  is  comprehended  which  is  so  seen  as  a  whole,  that  nothing 
of  it  is  hidden  from  the  seer.  But  if  God  is  seen  in  His 
essence,  He  is  seen  whole,  and  nothing  of  Him  is  hidden  from 
the  seer,  since  God  is  simple.  Therefore,  whoever  sees  His 
essence,  comprehends  Him. 

Obj.  3.  Further,  if  we  say  that  He  is  seen  as  a  whole,  but 
not  wholly,  it  may  be  contrarily  urged  that  wholly  refers  either 
to  the  mode  of  the  seer,  or  to  the  mode  of  the  thing  seen. 
But  he  who  sees  the  essence  of  God,  sees  Him  wholly,  if 
the  mode  of  the  thing  seen  is  considered;  forasmuch  as  he 
sees  Him  as  He  is;  also,  likewise,  he  sees  Him  wholly  if  the 
mode  of  the  seer  be  meant,  forasmuch  as  the  intellect  will 
with  its  full  power  see  the  divine  essence.  Therefore  all 
who  see  the  essence  of  God  see  Him  wholly;  therefore  they 
comprehend  Him. 

On  the  contrary,  It  is  written:  0  most  mighty,  great,  and 
powerful,  the  Lord  of  hosts  is  Thy  NamvC.  Great  in  counsel, 
and  incomprehensible  in  thought  (Jer.  xxxii.  18,  19).  There- 
fore He  cannot  be  comprehended. 

I  answer  that,  It  is  impossible  for  any  created  intellect 
to  comprehend  God;  yet  for  the  mind  to  attain  to  God  in 
some  degree  is  great  beatitude,  as  Augustine  says  {De  Verb, 
Dom.,  Serm.  xxxviii.). 


135  HOW  GOD  IS  KNOWN  BY  US     Q.  12.  Art.  7 

In  proof  of  this  we  must  consider  that  what  is  compre- 
hended is  perfectly  known;  and  that  is  perfectly  known 
which  is  known   so  far  as  it  can  be  known.      Thus,  if 
anything   which  is  capable  of  scientific  demonstration  is 
held   only  by  an  opinion  resting  on  a  probable  proof,  it 
is  not  comprehended;    as,  for  instance,  if   anyone  knows 
by  scientific  demonstration  that  a  triangle  has  three  angles 
equal   to  two  right  angles,  he  comprehends  that  truth; 
whereas    if    anyone    accepts    it    as    a    probable    opinion 
because  wise  men  or  most  men   teach  it,  he  cannot  be 
said  to  comprehend  the  thing  itself,  because  he  does  not 
attain  to  that  perfect  mode  of  knowledge  of  which  it  is 
intrinsically  capable.     But  no  created  intellect  can  attain 
to  that  perfect  mode  of  the  knowledge  of  the  divine  intellect 
whereof  it  is  intrinsically  capable.     Which  thus  appears — 
Everything  is  knowable  according  to  its  actuality.     But 
God,  whose  being  is  infinite,  as  was  shown  above  (Q.  VII.), 
is  infinitely  knowable.     Now  no  created  intellect  can  know 
God  infinitely.     For  the  created  intellect  knows  the  divine 
essence  more  or  less  perfectly  in  proportion  as  it  receives 
a  greater  or  lesser  light    of  glory.     Since  therefore   the  ■. 
created  light  of  glory  received  into  any  created  intellect  \ 
cannot  be  infinite,  it  is  clearly  impossible  for  any  created  \ 
intellect  to  know  God  in  an  infinite  degree.     Hence  it  is  i 
impossible  that  it  should  comprehend  God. 

Reply  Obj.  i.  Comprehension  is  twofold:  in  one  sense 
it  is  taken  strictly  and  properly,  according  as  something 
is  included  in  the  one  comprehending ;  and  thus  in  no  way  is 
God  comprehended  either  by  intellect,  or  in  any  other  way ; 
forasmuch  as  He  is  infinite  and  cannot  be  included  in  any 
finite  being;  so  that  no  finite  being  can  contain  Him  in- 
finitely, in  the  degree  of  His  own  infinity.  In  this  sense  we 
now  take  comprehension.  But  in  another  sense  comprehen- 
sion is  taken  more  largely  as  opposed  to  non-attai^iment ;  for 
he  who  attains  to  anyone  is  said  to  comprehend  him  when 
he  attains  to  him.  And  in  this  sense  God  is  comprehended 
by  the  blessed,  according  to  the  words,  /  held  him,  and  I  will 
not  let  him  go  (Cant.  iii.  4) ;  in  this  sense  also  are  to  be  under- 


Q.  12.  Art.  7      THE  "  SUMMA  THEOLOGICA  "  136 

stood  the  words  quoted  from  the  Apostle  concerning  com- 
prehension. And  in  this  way  comprehension  is  one  of  the 
three  prerogatives  of  the  soul,  responding  to  hope,  as  vision 
responds  to  faith,  and  fruition  responds  to  charity.  For 
even  among  ourselves  not  everything  seen  is  held  or 
possessed,  forasmuch  as  things  either  appear  sometimes 
afar  off,  or  they  are  not  in  our  power  of  attainment. 
Neither,  again,  do  we  always  enjoy  what  we  possess;  either 
because  we  find  no  pleasure  in  them,  or  because  such  things 
are  not  the  ultimate  end  of  our  desire,  so  as  to  satisfy  and 
quell  it.  But  the  blessed  possess  these  three  things  in  God; 
because  they  see  Him,  and  in  seeing  him,  possess  Him  as 
present,  having  the  power  to  see  Him  always;  and  possessing 
Him,  they  enjoy  Him  as  the  ultimate  fulfilment  of  desire. 

Reply  Obj.  2.  God  is  called  incomprehensible  not  because 
anything  of  Him  is  not  seen;  but  because  He  is  not  seen  as 
perfectly  as  He  is  capable  of  being  seen;  thus  when  any 
demonstrable  proposition  is  known  by  a  probable  reason  only, 
it  does  not  follow  that  any  part  of  it  is  unknown,  either  the 
subject,  or  the  predicate,  or  the  composition;  but  that  it 
is  not  as  perfectly  known  as  it  is  capable  of  being  known. 
Hence  Augustine,  in  his  definition  of  comprehension,  says 
the  whole  is  comprehended  when  it  is  seen  in  such  a  way 
that  nothing  of  it  is  hidden  from  the  seer,  or  when  its  boun- 
daries can  be  completely  viewed  or  traced ;  for  the  boundaries 
of  a  thing  are  said  to  be  completely  surveyed  when  the  end 
of  the  knowledge  of  it  is  attained. 

Reply  Obj.  3.  The  word  wholly  denotes  a  mode  of  the 
object;  not  that  the  whole  object  does  not  come  under 
knowledge,  but  that  the  mode  of  the  object  is  not  the 
mode  of  the  one  who  knows.  Therefore,  he  who  sees  God's 
essence,  sees  in  Him  that  He  exists  infinitely,  and  is  in- 
finitely knowable;  nevertheless,  this  infinite  mode  does 
not  extend  to  enable  the  knower  to  know  infinitely;  thus, 
for  instance,  a  person  can  have  a  probable  opinion  that  a 
proposition  is  demonstrable,  although  he  himself  does  not 
know  it  as  demonstrated. 


137  HOW  GOD  IS  KNOWN  BY  US    Q.  12.  Art.  8 

Eighth  Article, 
whether  those  who  see  the  essence  of  god  see  all 

IN   GOD  ? 

We  proceed  thus  to  the  Eighth  Article  : — 

Objection  i.  It  seems  that  those  who  see  the  essence  of 
God  see  all  things  in  God.  For  Gregory  says  {Dialog,  iv.) : 
What  do  they  not  see,  who  see  Him  Who  sees  all  things  ?  But 
God  sees  all  things.  Therefore,  those  who  see  God  see  all 
things. 

Ohj.  2.  Further,  whoever  sees  a  mirror,  sees  what  is 
reflected  in  the  mirror.  But  all  actual  or  possible  things 
shine  forth  in  God  as  in  a  mirror;  for  He  knows  all  things 
in  Himself.  Therefore,  whoever  sees  God,  sees  all  actual 
things  in  Him,  and  also  all  possible  things. 

Ohj.  3.  Further,  whoever  understands  the  greater,  can 
understand  the  least,  as  is  said  in  De  Anima  iii.  But  all 
that  God  does,  or  can  do,  are  less  than  His  essence.  There- 
fore, whoever  understands  God,  can  understand  all  that  God 
does,  or  can  do. 

Ohj.  4.  Further,  the  rational  creature  naturally  desires 
to  know  all  things.  Therefore,  if  in  seeing  God  it  does  not 
know  all  things,  its  natural  desire  will  not  rest  satisfied; 
thus,  in  seeing  God  it  will  not  be  fully  happy;  which  is 
incongruous .     Therefore,  he  who  sees  God  knows  all  things. 

On  the  contrary,  The  angels  see  the  essence  of  God;  and 
yet  do  not  know  all  things.  For,  as  Dionysius  says  [Ccel. 
Hier.  vii.),  the  inferior  angels  are  cleansed  from  ignorance  hy 
the  superior  angels.  Also  they  are  ignorant  of  future  con- 
tingent things,  and  of  secret  thoughts;  for  this  knowledge 
belongs  to  God  alone.  Therefore,  whosoever  sees  the  essence 
of  God,  does  not  know  all  things. 

/  answer  that,  The  created  intellect,  in  seeing  the  divine 
essence,  does  not  see  in  it  all  that  God  does  or  can  do. 
For  it  is  manifest  that  things  are  seen  in  God  as  they  are 
in  Him.  But  all  other  things  are  in  God  as  effects  are 
in  the  power  of  their  cause.     Therefore  all  things  are  seen 


Q.  12.  Art.  8    THE  "  SUMMA  THEOLOGICA  "  138 

in  God  as  an  effect  is  seen  in  its  cause.  Now  it  is  clear  that 
the  more  perfectly  a  cause  is  seen,  the  more  of  its  effects  can 
be  seen  in  it.  For  whoever  has  a  lofty  understanding, 
as  soon  as  one  demonstrative  principle  is  put  before  him 
can  gather  the  knowledge  of  many  conclusions ;  but  this  is 
beyond  one  of  a  weaker  intellect,  for  he  needs  things  to  be 
explained  to  him  separately.  And  so  an  intellect  can  know 
all  the  effects  of  a  cause  and  the  reasons  for  those  effects 
in  the  cause  itself,  if  it  comprehends  the  cause  wholly. 
Now  no  created  intellect  can  comprehend  God  wholly,  as 
shown  above  (A.  7) .  Therefore  no  created  intellect  in  seeing 
God  can  know  all  that  God  does  or  can  do,  for  this  would  be 
to  comprehend  His  power ;  but  of  what  God  does  or  can  do 
any  intellect  can  know  the  more,  the  more  perfectly  it  sees 
God. 

Reply  Obj.  i.  Gregory  speaks  as  regards  the  object  being 
sufficient,  namely,  God,  who  in  Himself  sufficiently  contains 
and  shows  forth  all  things ;  but  it  does  not  follow  that  who- 
ever sees  God  knows  all  things,  for  he  does  not  perfectly 
comprehend  Him. 

Reply  Obj.  2.  It  is  not  necessary  that  whoever  sees  a 
mirror  should  see  all  that  is  in  the  mirror,  unless  his  glance 
comprehends  the  mirror  itself. 

Reply  Obj.  3.  Although  it  is  more  to  see  God  than  to  see 
all  things  else,  still  it  is  a  greater  thing  to  see  Him  so  that 
all  things  are  known  in  Him,  than  to  see  Him  in  such  a  way 
that  not  all  things,  but  the  fewer  or  the  more,  are  known  in 
Him.  For  it  has  been  shown  in  this  article  that  the  more 
things  are  known  in  God  according  as  He  is  seen  more  or 
less  perfectly. 

Reply  Obj.  4.  The  natural  desire  of  the  rational  creature 
is  to  know  everything  that  belongs  to  the  perfection  of  the 
intellect,  namely,  the  species  and  genera  of  things  and  their 
types,  and  these  everyone  who  sees  the  divine  essence  will 
see  in  God.  But  to  know  other  singulars,  their  thoughts  and 
their  deeds  does  not  belong  to  the  perfection  of  the  created 
intellect  nor  does  its  natural  desire  go  out  to  these  things; 
neither,  again,  does  it  desire  to  know  things  that  exist  not  as 


139  HOW  GOD  IS  KNOWN  BY  US     Q.  12.  Art.  9 

yet,  but  which  God  can  call  into  being.  Yet  if  God  alone 
were  seen,  Who  is  the  fount  and  principle  of  all  being  and 
of  all  truth.  He  would  so  fill  the  natural  desire  of  knowledge 
that  nothing  else  would  be  desired,  and  the  seer  would  be 
completely  beatified.  Hence  Augustine  says  {Confess,  v.) : 
Unhappy  the  man  who  knoweth  all  these  (that  is,  all  creatures) 
and  knoweth  not  Thee  I  but  happy  whoso  knoweth  Thee  although 
he  know  not  these.  And  whoso  knoweth  both  Thee  and  them 
is  not  the  happier  for  them,  but  for  Thee  alone. 


Ninth  Article. 

whether  what  is  seen  in  god,  by  those  who  see  the 
divine  essence,  is  seen  through  any  similitude  ? 

We  proceed  thus  to  the  Ninth  Article : — 

Objection  i.  It  seems  that  what  is  seen  in  God  by  those 
who  see  the  divine  essence,  is  seen  by  means  of  some 
similitude.  For  every  kind  of  knowledge  comes  about  by 
the  knower  being  assimilated  to  the  object  known.  For  thus 
the  intellect  in  act  becomes  the  actual  intelligible,  and  the 
sense  in  act  becomes  the  actual  sensible,  inasmuch  as  it  is 
informed  by  a  similitude  of  the  object,  as  the  eye  by  the 
similitude  of  colour.  Therefore,  if  the  intellect  of  one  who 
sees  the  divine  essence  understands  any  creatures  in  God, 
it  must  be  informed  by  their  similitudes. 

Obj.  2.  Further,  what  we  have  seen,  we  keep  in  memory. 
But  Paul,  seeing  the  essence  of  God  whilst  in  ecstasy,  when 
he  had  ceased  to  see  the  divine  essence,  as  Augustine  says 
(Gen.  ad  lit.  xii.  28,  34),  remembered  many  of  the  things  he 
had  seen  in  the  rapture ;  hence  he  said :  I  have  heard  secret 
words  which  it  is  not  granted  to  man  to  utter  (2  Cor.  xii.  4). 
Therefore  it  must  be  said  that  certain  similitudes  of  what  he 
remembered,  remained  in  his  mind;  and  in  the  same  way, 
when  he  actually  saw  the  essence  of  God,  he  had  certain 
similitudes  or  ideas  of  what  he  actually  saw  in  it. 

071  the  contrary,  A  mirror  and  what  is  in  it  are  seen  by 
means  of  one  likeness.  But  all  things  are  seen  in  God  as 
in  an  intelligible  mirror.     Therefore,  if  God  Himself  is  not 


Q.  12.  Art.  9    THE  "  SUMMA  THEOLOGICA  ''  140 

seen  by  any  similitude  but  by  His  own  essence,  neither  are 
the  things  seen  in  Him  seen  by  any  similitudes  or  ideas. 

/  answer  that,  Those  who  see  the  divine  essence  see  what 
they  see  in  God  not  by  any  likeness,  but  by  the  divine 
essence  itself  united  to  their  intellect.  For  each  thing  is 
known  in  so  far  as  its  likeness  is  in  the  one  who  knows.  Now 
this  takes  place  in  two  ways.  For  as  things  which  are  like 
to  one  and  the  same  thing  are  like  to  each  other,  the  cog- 
nitive faculty  can  be  assimilated  to  any  knowable  object 
in  two  ways.  In  one  way  it  is  assimilated  by  the  object 
itself,  when  it  is  directly  informed  by  a  similitude,  and  then 
the  object  is  known  in  itself.  In  another  way  when  informed 
by  a  similitude  which  resembles  the  object;  and  in  this  way 
the  knowledge  is  not  of  the  thing  in  itself,  but  of  the  thing 
in  its  likeness.  For  the  knowledge  of  a  man  in  himself  differs 
from  the  knowledge  of  him  in  his  image.  Hence  to  know 
things  thus  by  their  likeness  in  the  one  who  knows,  is  to 
know  them  in  themselves  or  in  their  own  nature;  whereas 
to  know  them  by  their  similitudes  pre-existing  in  God,  is  to 
see  them  in  God.  Now  there  is  a  difference  between  these 
two  kinds  of  knowledge.  Hence,  according  to  the  knowledge 
whereby  things  are  known  by  those  who  see  the  essence  of 
God,  they  are  seen  in  God  Himself  not  by  any  other  simili- 
tudes but  by  the  divine  essence  alone  present  to  the  intellect ; 
by  which  also  God  Himself  is  seen. 

Reply  Ohj.  i.  The  created  intellect  of  one  who  sees  God 
is  assimilated  to  what  is  seen  in  God,  inasmuch  as  it  is 
united  to  the  divine  essence,  in  which  the  similitudes  of 
all  things  pre-exist. 

Reply  Ohj.  2.  Some  of  the  cognitive  faculties  form 
other  images  from  those  first  conceived;  thus  the  imagina- 
tion from  the  preconceived  images  of  a  mountain  and  of  gold 
can  form  the  likeness  of  a  golden  mountain ;  and  the  intellect, 
from  the  preconceived  ideas  of  genus  and  difference,  forms 
the  idea  of  species;  in  like  manner  from  the  similitude  of 
an  image  we  can  form  in  our  minds  the  similitude  of  the 
original  of  the  image.  Thus  Paul,  or  any  other  person  who 
sees  God,  by  the  very  vision  of  the  divine  essence,  can  form 


141  HOW  GOD  IS  KNOWN  BY  US     Q.  12.  Art.  10 

in  himself  the  simiUtudes  of  what  is  seen  in  the  divine 
essence,  which  remained  in  Paul  even  when  he  had  ceased 
to  see  the  essence  of  God.  Still  this  kind  of  vision  whereby 
things  are  seen  by  this  likeness  thus  conceived,  is  not  the 
same  as  that  whereby  things  are  seen  in  God. 


Tenth  Article. 

whether  those  who  see  the  essence  of  god   see  all 
they  see  in  it  at  the  same  time  ? 

We  proceed  thus  to  the  Tenth  Article  : — 

Objection  i.  It  seems  that  those  who  see  the  essence  of 
God  do  not  see  all  they  see  in  Him  at  one  and  the  same 
time.  For,  according  to  the  Philosopher  (Topic,  ii.) :  It 
may  happen  that  many  things  are  known,  hut  only  one  is 
understood.  But  what  is  seen  in  God,  is  understood;  for 
God  is  seen  by  the  intellect.  Therefore  those  who  see 
God  do  not  see  all  in  Him  at  the  same  time. 

Obj.  2.  Further,  Augustine  says  (Gen.  ad  lit.  viii.  22,  23), 
God  moves  the  spiritual  creature  according  to  time — that  is, 
by  intelligence  and  affection.  But  the  spiritual  creature  is 
the  angel,  who  sees  God.  Therefore  those  who  see  God 
understand  and  are  affected  successively;  for  time  means 
succession. 

On  the  contrary,  Augustine  says  (De  Trin.  xvi.):  Our 
thoughts  will  not  be  unstable,  going  to  and  fro  from  one  thing  to 
another  ;  but  we  shall  see  all  we  know  at  one  glance. 

I  answer  that,  What  is  seen  in  the  Word  is  seen  not  suc- 
cessively, but  at  the  same  time.  In  proof  whereof,  we 
ourselves  cannot  know  many  things  all  at  once,  forasmuch  as 
we  understand  many  things  by  means  of  many  ideas.  But 
our  intellect  cannot  be  actually  informed  by  many  diverse 
ideas  at  the  same  time,  so  as  to  understand  by  them;  as  one 
body  cannot  bear  different  shapes  simultaneously.  Hence, 
when  many  things  can  be  understood  by  one  idea,  they  are 
understood  at  the  same  time;  as  the  parts  of  a  whole  are 
understood  successively,  and  not  all  at  the  same  time,  if  each 
one  is  understood  by  its  own  idea;  whereas  if  all  are  under- 


Q.  12.  Art.  ii    THE  "  SUMMA  THEOLOGICA  "  142 

stood  under  the  one  idea  of  the  whole,  they  are  understood 
simultaneously.  Now  it  was  shown  above  that  things  seen 
in  God,  are  not  seen  singly  by  their  own  similitude;  but 
all  are  seen  by  the  one  essence  of  God.  Hence  they  are  seen 
simultaneously,  and  not  successively. 

Reply  Obj.  i.  We  understand  one  thing  only  when  we 
understand  by  one  idea;  but  many  things  understood 
by  one  idea  are  understood  simultaneously,  as  in  the  idea 
of  a  man  we  understand  animal  and  rational ;  and  in  the 
idea  of  a  house  we  understand  the  wall  and  the  roof. 

Reply  Obj.  2.  As  regards  their  natural  knowledge,  whereby 
they  know  things  by  diverse  ideas  given  them,  the  angels 
do  not  know  all  things  simultaneously,  and  thus  they  are 
moved  in  the  act  of  understanding  according  to  time ;  but  as 
regards  what  they  see  in  God,  they  see  all  at  the  same  time. 

Eleventh  Article, 
whether  anyone  in  this  life  can  see  the  essence  of 

GOD  ? 

We  proceed  thus  to  the  Eleventh  Article  : — 

Objection  i.  It  seems  that  one  can  in  this  life  see  the 
divine  essence.  For  Jacob  said :  /  have  seen  God  face  to  face 
(Gen.  xxxii.  30).  But  to  see  Him  face  to  face  is  to  see  His 
essence,  as  appears  from  the  words:  We  see  now  in  a  glass 
and  in  a  dark  manner,  but  then  face  to  face  (i  Cor.  xiii.  12). 
Therefore  God  can  be  seen  in  this  life  in  His  essence. 

Ohj.  2.  Further,  the  Lord  said  of  Moses:  /  speak  to  him 
mouth  to  mouth,  and  plainly,  and  not  by  riddles  and  figures 
doth  he  see  the  Lord  (Num.  xii.  8) ;  but  this  is  to  see  God  in 
His  essence.  Therefore  it  is  possible  to  see  the  essence  of 
God  in  this  life. 

Obj.  3.  Further,  that  wherein  we  know  all  other  things, 
and  whereby  we  judge  of  other  things,  is  known  in  itself  to 
us.  But  even  now  we  know  all  things  in  God ;  for  Augustine 
says  {Confess,  viii.) :  If  we  both  see  that  what  you  say  is  true, 
and  we  both  see  that  what  I  say  is  true  ;  where,  I  ask,  do  we 
see  this  ?  neither  I  in  thee,  nor  thou  in  me  ;  but  both  of  us  in 


143  HOW  GOD  IS  KNOWN  BY  US    Q.  12.  Art.  11 

the  very  incommutable  truth  itself  above  our  minds.  He  also 
says  [De  Vera  Relig.  xxx.)  that,  We  judge  of  all  things  accord- 
ing to  the  divine  truth  ;  and  (De  Trin.  xii.)  that,  it  is  the  duty 
of  reason  to  judge  of  these  corporeal  things  according  to  the 
incorporeal  and  eternal  ideas  ;  which  unless  they  were  above 
the  mind,  could  not  be  incommutable.  Therefore  even  in  this 
Hfe  we  see  God  Himself. 

Obj.  4.  Further,  according  to  Augustine  [Gen.  ad  lit.  xii. 
24,  25),  those  things  that  are  in  the  soul  by  their  essence 
are  seen  by  intellectual  vision.  But  intellectual  vision  is 
of  intelligible  things,  not  by  simihtudes,  but  by  their  very 
essences,  as  he  also  says  [ibid.).  Therefore,  since  God  is  in 
our  soul  by  His  essence,  it  follows  that  He  is  seen  by  us 
in  His  essence. 

On  the  contrary,  It  is  written,  Man  shall  not  see  Me,  and 
live  (Exod.  xxxiii.  20),  and  a  gloss  upon  this  says:  In  this 
mortal  life  God  can  be  seen  by  certain  images,  but  not  by  the 
likeness  itself  of  His  own  nature. 

I  answer  that,  God  cannot  be  seen  in  His  essence  by  a  mere 
human  being,  except  he  be  separated  from  this  mortal  life. 
The  reason  is,  because,  as  was  said  above  (A.  4j,  the  mode  of 
knowledge  follows  the  mode  of  the  nature  of  the  knower. 
But  our  soul,  as  long  as  we  live  in  this  life,  has  its  being  in 
corporeal  matter ;  hence  naturally  it  knows  only  what  has  a 
form  in  matter,  or  what  can  be  known  by  such  a  form. 
Now  it  is  evident  that  the  divine  essence  cannot  be  known 
through  the  nature  of  material  things.  For  it  was  shown 
above  (AA.  2,  9)  that  the  knowledge  of  God  by  means  of 
any  created  similitude  is  not  the  vision  of  His  essence. 
Hence  it  is  impossible  for  the  soul  of  man  in  this  life  to  see 
the  essence  of  God.  This  can  be  seen  in  the  fact  that  the 
more  our  soul  is  abstracted  from  corporeal  things,  the  more 
it  is  capable  of  receiving  abstract  intelligible  things. 
Hence  in  dreams  and  alienations  of  the  bodily  senses  divine 
revelations  and  foresight  of  future  events  are  perceived  the 
more  clearly.  It  is  not  possible,  therefore,  that  the  soul  in 
this  mortal  life  should  be  raised  up  to  the  supreme  of 
intelligible  objects,  that  is,  to  the  divine  essence. 


Q.  12.  Art.  ii    THE  "  SUMMA  THEOLOGICA  '*  144 

Reply  Ohj.  i.  According  to  Dionysius  [Coel.  Hier.  iv.),  a 
man  is  said  in  the  Scriptures  to  see  God  in  the  sense  that 
certain  figures  are  formed  in  the  senses  or  imagination, 
according  to  some  simiHtude  representing  in  part  the  divinity. 
So  when  Jacob  says,  I  have  seen  God  face  to  face,  this  does  not 
mean  the  divine  essence,  but  some  figure  representing  God. 
And  this  is  to  be  referred  to  some  high  mode  of  prophecy,  so 
that  God  seems  to  speak,  though  in  an  imaginary  vision ;  as 
will  later  be  explained  (II.  II.,  Q.  CLXXIV.)  in  treating  of 
the  degrees  of  prophecy.  We  may  also  say  that  Jacob 
spoke  thus  to  designate  some  exalted  intellectual  contem- 
plation, above  the  ordinary  state. 

Reply  Ohj.  2.  As  God  works  miracles  in  corporeal  things, 
so  also  He  does  supernatural  wonders  above  the  common 
order,  raising  the  minds  of  some  living  in  the  flesh  beyond 
the  use  of  sense,  even  up  to  the  vision  of  His  own  essence; 
as  Augustine  says  [Gen,  ad  lit.  xii.  26,  27,  28)  of  Moses, 
the  teacher  of  the  Jews;  and  of  Paul,  the  teacher  of  the 
Gentiles.  This  will  be  treated  more  fully  in  the  question  of 
rapture  (II.  IL,  Q.  CLXXV.). 

Reply  Ohj.  3.  All  things  are  said  to  be  seen  in  God,  and 
all  things  are  judged  in  Him,  because  by  the  participation 
of  His  light  we  know  and  judge  all  things;  for  the  light  of 
natural  reason  itself  is  a  participation  of  the  divine  light; 
as  likewise  we  are  said  to  see  and  judge  of  sensible  things 
in  the  sun,  that  is,  by  the  sun's  light.  Hence  Augus- 
tine says  (Soliloq.  i.  8),  The  lessons  of  instruction  can  only 
he  seen  as  it  were  hy  their  own  sun,  namely  God.  As  therefore 
in  order  to  see  a  sensible  object  it  is  not  necessary  to  see  the 
substance  of  the  sun,  so  in  like  manner  to  see  any  intelligible 
object,  it  is  not  necessary  to  see  the  essence  of  God. 

Reply  Ohj.  4.  Intellectual  vision  is  of  the  things  which 
are  in  the  soul  by  their  essence,  as  intelligible  things  are  in 
the  intellect.  And  thus  God  is  in  the  souls  of  the  blessed; 
not  thus  is  He  in  our  soul,  but  by  presence,  essence,  and 
power. 


145  HOW  GOD  IS  KNOWN  BY  US    Q.  12.  Art.  12 


Twelfth  Article, 
whether  god  can  be  known  in  this  life  by  natural 

REASON  ? 

We  proceed  thus  to  the  Twelfth  Article  : — ■ 

Objection  i.  It  seems  that  by  natural  reason  we  cannot 
know  God  in  this  Hfe.  For  Boethius  says  [De  Consol.  v.) 
that  reason  does  not  grasp  simple  form.  But  God  is  a 
supremely  simple  form,  as  was  shown  above  (Q.  III.  A.  7): 
Therefore  natural  reason  cannot  attain  to  know  Him. 

Obj.  2.  Further,  the  soul  understands  nothing  by  natural 
reason  without  the  use  of  the  imagination.  But  we  cannot 
have  an  imagination  of  God,  Who  is  incorporeal.  There- 
fore we  cannot  know  God  by  natural  knowledge. 

Obj.  3.  Further,  the  knowledge  of  natural  reason  belongs 
to  both  good  and  evil,  inasmuch  as  they  have  a  common 
nature.  But  the  knowledge  of  God  belongs  only  to  the 
good;  for  Augustine  says  {De  Trin.  i.):  The  weak  eye  of  the 
human  mind  is  not  fixed  on  that  excellent  light  unless  purified 
by  the  justice  of  faith.  Therefore  God  cannot  be  known 
by  natural  reason. 

On  the  contrary,  It  is  written  (Rom.  i.  19),  That  which 
is  known  of  God,  namely,  what  can  be  known  of  God  by 
natural  reason,  is  manifest  in  them, 

I  answer  that,  Our  natural  knowledge  begins  from  sense. 
Hence  our  natural  knowledge  can  go  as  far  as  it  can  be  led 
by  sensible  things.  But  our  mind  cannot  be  led  by  sense  so 
far  as  to  see  the  essence  of  God ;  because  the  sensible  effects 
of  God  do  not  equal  the  power  of  God  as  their  cause.  Hence 
from  the  knowledge  of  sensible  things  the  whole  power  of 
God  cannot  be  known;  nor  therefore  can  His  essence  be  seen. 
But  because  they  are  His  effects  and  depend  on  their  cause, 
we  can  be  led  from  them  so  far  as  to  know  of  God  whether  He 
exists,  and  to  know  of  Him  what  must  necessarily  belong  to 
Him,  as  the  first. cause  of  all  things,  exceeding  all  things 
caused  by  Him. 

Hence  we  know  that  His  relationship  with  creatures  so 
I*  10 


Q.  12.  Art.  13      THE  "  SUMMA  THEOLOGICA  "  146 

far  as  to  be  the  cause  of  them  all ;  also  that  creatures  differ 
from  Him,  inasmuch  as  He  is  not  in  any  way  part  of  what 
is  caused  by  Him;  and  that  creatures  are  not  removed 
from  Him  by  reason  of  any  defect  on  His  part,  but  because 
He  superexceeds  them  all. 

Reply  Obj.  i.  Reason  cannot  reach  up  to  simple  form, 
so  as  to  know  what  it  is  ;  but  it  can  know  whether  it  is. 

Reply  Obj.  2.  God  is  known  by  natural  knowledge  through 
the  images  of  His  effects. 

Reply  Obj.  3.  As  the  knowledge  of  God's  essence  is  by 
grace,  it  belongs  only  to  the  good;  but  the  knowledge  of 
Him  by  natural  reason  can  belong  to  both  good  and  bad ; 
and  hence  Augustine  says  {Retract,  i.),  retracting  what 
he  had  said  before:  I  do  not  approve  what  I  said  in  prayer, 
*  God  who  wiliest  that  only  the  pure  should  know  truth.'  For  if 
can  be  answered  that  many  who  are  not  pure  can  know  many 
truths,  that  is,  by  natural  reason. 

Thirteenth  Article. 

whether  by  grace  a  higher  knowledge  of  god  can  be 
obtained  than  by  natural  reason  ? 

We  proceed  thus  to  the  Thirteenth  Article  : — 

Objection  i.  It  seems  that  by  grace  a  higher  knowledge  of 
God  is  not  obtained  than  by  natural  reason.  For  Dionysius 
says  {De  Mystica  Theol.  i.),  that  whoever  is  the  more  united 
to  God  in  this  life,  is  united  to  Him  as  to  one  entirely  un- 
known. He  says  the  same  of  Moses,  who  nevertheless  ob- 
tained a  certain  excellence  by  the  knowledge  conferred  by 
grace.  But  to  be  united  to  God  while  ignoring  of  Him  what 
He  is,  comes  about  also  by  natural  reason.  Therefore 
God  is  not  more  known  to  us  by  grace  than  by  natural 
reason. 

Obj.  2.  Further,  we  can  acquire  the  knowledge  of  divine 
things  by  natural  reason  only  through  the  imagination; 
and  the  same  applies  to  the  knowledge  given  by  grace. 
For  Dionysius  says  {Ccel.  Hier.  i.)  that  it  is  impossible  for 
the  divine  ray  to  shine  upon  us  except  as  screened  round  about 


T47  HOW  GOD  IS  KNOWN  BY  US    Q.  12.  Art.  13 

by  the  many  coloured  sacred  veils.  Therefore  we  cannot 
know  God  more  fully  by  grace  than  by  natural  reason. 

Obj.  3.  Further,  our  intellect  adheres  to  God  by  the  grace 
of  faith.  But  faith  does  not  seem  to  be  knowledge;  for 
Gregory  says  {Homil.  xxvi.  in  Ev.)  that  things  not  seen  are  the 
objects  of  faith,  and  not  of  knowledge.  Therefore  there  is  not 
given  to  us  a  more  excellent  knowledge  of  God  by  grace. 

On  the  contrary,  The  Apostle  says  that  God  hath  revealed 
to  us  by  His  Spirit,  what  none  of  the  princes  of  this  world  knew 
(i  Cor.  ii.  10),  namely,  the  philosophers,  as  the  gloss  expounds. 

/  answer  that.  We  have  a  more  perfect  knowledge  of  God 
by  grace  than  by  natural  reason.  Which  is  proved  thus. 
The  knowledge  which  we  have  by  natural  reason  contains 
two  things:  images  derived  from  the  sensible  objects;  and 
the^atural  intelligible  light,  enabling^ jisjto  abstract  from 
them  intelHgible  conceptions. 

Now  in  both  of  these,  human  knowledge  is  assisted  by  the 
revelation  of  grace.  For  the  intellect's  natural  light  is 
strengthened  by  the  infusion  of  gratuitous  light;  and  some- 
times also  the  images  in  the  human  imagination  are  divinely 
formed,  so  as  to  express  divine  things  better  than  those  do 
which  we  receive  from  sensible  objects,  as  appears  in  pro- 
phetic visions;  while  sometimes  sensible  things,  or  even 
voices,  are  divinely  formed  to  express  some  divine  mean- 
ing; as  in  the  Baptism,  the  Holy  Ghost  was  seen  in  the 
shape  of  a  dove,  and  the  voice  of  the  Father  was  heard. 
This  is  My  beloved  Son  (Matt:  iii.  17). 

Reply  Obj.  i.  Although  by  the  revelation  of  grace  in  this 
life  we  cannot  know  of  God  what  He  is,  and  thus  are  united 
to  Him  as  to  one  unknown;  still  we  know  Him  more  fully 
according  as  many  and  more  excellent  of  His  effects  are 
demonstrated  to  us,  and  according  as  we  attribute  to  Him 
some  things  known  by  divine  revelation,  to  which  natural 
reason  cannot  reach,  as,  for  instance,  that  God  is  Three  and 
One. 

Reply  Obj.  2.  From  the  images  either  received  from  sense 
in  the  natural  order,  or  divinely  formed  in  the  imagination, 
we  have  so  much  the  more  excellent  intellectual  knowledge^ 


Q.  12.  Art.  13    THE  "  SUMMA  THEOLOGICA  "  148 

the  stronger  the  intelligible  Hght  is  in  man ;  and  thus  through 
the  revelation  given  by  the  images  a  fuller  knowledge  is 
received  by  the  infusion  of  the  divine  light. 

Reply  Ohj.  3.  Faith  is  a  kind  of  knowledge,  inasmuch  as 
the  intellect  is  determined  by  faith  to  some  knowable 
object.  But  this  determination  to  one  object  does  not  pro- 
ceed from  the  vision  of  the  believer,  but  from  the  vision  of  Him 
who  is  believed.  Thus,  as  far  as  faith  falls  short  of  vision, 
it  falls  short  of  the  knowledge  which  belongs  to  science,  for 
science  determines  the  intellect  to  one  object  by  the  vision 
and  understanding  of  first  principles. 


QUESTION  XIII. 

THE  NAMES  OF  GOD. 

{In  Twelve  Articles.) 

After  the  consideration  of  those  things  which  belong  to  the 
divine  knowledge,  we  now  proceed  to  the  consideration  of 
the  divine  names.  For  everything  is  named  by  us  according 
to  our  knowledge  of  it. 

Under  this  head,  there  are  twelve  points  for  inquiry, 
(i)  Whether  God  can  be  named  by  us  ?  (2)  Whether  any 
names  applied  to  God  are  predicated  of  Him  substantially  ? 
(3)  Whether  any  names  applied  to  God  are  said  of  Him 
literally,  or  are  all  to  be  taken  metaphorically  ?  (4) 
Whether  any  names  applied  to  God  are  synonymous  ? 
(5)  Whether  some  names  are  applied  to  God  and  to 
creatures  univocally  or  equivocally?  (6)  Whether,  sup- 
posing they  are  applied  analogically,  they  are  applied 
first  to  God  or  to  creatures  ?  (7)  Whether  any  names  are 
applicable  to  God  from  time  ?  (8)  Whether  this  name  God 
is  a  name  of  nature,  or  of  the  operation  ?  (9)  Whether 
this  name  God  is  a  communicable  name  ?  (10)  Whether  it 
is  taken  univocally  or  equivocally  as  signifying  God,  by 
nature,  by  participation,  and  by  opinion  ?  (11)  Whether 
this  name,  Who  is,  is  the  supremely  appropriate  name  of 
God  ?  (12)  Whether  affirmative  propositions  can  be  formed 
about  God  ? 

First  Article, 
whether  a  name  can  be  given  to  god  ? 

We  proceed  th^ts  to  the  First  Article  : — 
Objection  i.   It  seems  that  no  name  can  be  given  to  God. 
For  Dionysius  says    {Div.  Nom.  i.)  that,  Of  Him  there   is 

149 


g.  13.  Art.  I    THE  '*  SUMMA  TFIEOLOGICA  "  150 

neither  name,  nor  can  one  he  found  of  Him  ;  and  it  is  written: 
What  is  His  name,  and  iiuhat  is  the  name  of  His  Son,  if  thou 
know  est  ?  (Pro  v.  xxx.  4). 

Obj.  2.  Further,  every  name  is  either  abstract  or  concrete. 
But  concrete  names  do  not  belong  to  God,  since  He  is 
simple,  nor  do  abstract  names  belong  to  Him,  forasmuch  as 
they  do  not  signify  any  perfect  subsisting  thing.  Therefore 
no  name  can  be  said  of  God. 

Obj.  3.  Further,  nouns  are  taken  to  signify  substance 
with  quality;  verbs  and  participles  signify  substance  with 
time;  pronouns  the  same  with  demonstration  or  relation. 
But  none  of  these  can  be  applied  to  God,  for  He  has  no 
quality,  nor  accident,  nor  time;  moreover.  He  cannot  be 
felt,  so  as  to  be  pointed  out;  nor  can  He  be  described  by 
relation,  inasmuch  as  relations  serve  to  recall  a  thing  men- 
tioned before  by  nouns,  participles,  or  demonstrative  pro- 
nouns.    Therefore  God  cannot  in  any  way  be  named  by  us. 

On  the  contrary,  It  is  WTitten  (Exod.  xv.  3) :  The  Lord  is 
a  man  of  war,  Almighty  is  His  name. 

I  answer  that.  Since  according  to  the  Philosopher  [Peri- 
herm.  i.),  words  are  signs  of  ideas,  and  ideas  the  similitude 
of  things,  it  is  evident  that  words  relate  to  the  meaning  of 
things  signified  through  the  medium  of  the  intellectual  con- 
ception. It  follows  therefore  that  we  can  give  a  name  to  any- 
thing in  as  far  as  we  can  understand  it.  Now  it  was  shown 
above  (Q.  XH.,  AA.  11, 12)  that  in  this  life  we  cannot  see  the 
essence  of  God ;  but  we  know  God  from  creatures  as  their 
principle,  and  also  by  way  of  excellence  and  remotion.  In 
this  way  therefore  He  can  be  named  by  us  from  creatures, 
yet  not  so  that  the  name  which  signifies  Him  expresses 
the  divine  essence  in  itself.  Thus  the  name  man  expresses 
the  essence  of  man  in  himself,  since  it  signifies  the  definition 
of  man  by  manifesting  his  essence;  for  the  idea  expressed 
by  the  name  is  the  definition. 

Reply  Obj.  1.  The  reason  why  God  has  no  name,  or  is 
said  to  be  above  being  named,  is  because  His  essence  is 
above  all  that  we  understand  about  God  and  signify  in 
word. 


151  THE  NAMES  OF  GOD  Q.  13.  Art.  i 

Reply  Ohj.  2.  Because  we  know  and  name  God  from  crea- 
tures, the  names  we  attribute  to  God  signify  what  belongs 
to  material  creatures,  of  which  the  knowledge  is  natural 
to  us.  And  because  in  creatures  of  this  kind  what  is  perfect 
and  subsistent  is  compound;  whereas  their  form  is  not 
a  complete  subsisting  thing,  but  rather  is  that  whereby  a 
thing  is ;  hence  it  follows  that  all  names  used  by  us  to  signify 
a  complete  subsisting  thing  must  have  a  concrete  meaning 
as  applicable  to  compound  things;  whereas  names  given  to 
signify  simple  forms,  signify  a  thing  not  as  subsisting, 
but  as  that  whereby  a  thing  is;  as,  for  instance,  whiteness 
signifies  that  whereby  a  thing  is  white.  And  as  God  is 
simple,  and  subsisting,  we  attribute  to  Him  abstract  names 
to  signify  His  simplicity,  and  concrete  names  to  signify 
His  subsistence  and  perfection,  although  both  these  kinds 
of  names  fail  to  express  His  mode  of  being,  forasmuch  as 
our  intellect  does  not  know  Him  in  this  life  as  He  is. 

Reply  Ohj.  3.  To  signify  substance  with  quality  is  to 
signify  the  suppositum  with  a  nature  or  determined  form 
in  which  it  subsists.  Hence,  as  some  things  are  said  of  God 
in  a  concrete  sense,  to  signify  His  subsistence  and  perfection, 
so  likewise  nouns  are  applied  to  God  signifying  substance 
with  quality.  Further,  verbs  and  participles  which  signify 
time,  are  applied  to  Him  because  His  eternity  includes  all 
time.  For  as  we  can  apprehend  and  signify  simple  sub- 
sistences only  by  way  of  compound  things,  so  we  can  under- 
stand and  express  simple  eternity  only  by  way  of  temporal 
things,  because  our  intellect  has  a  natural  affinity  to  com- 
pound and  temporal  things.  But  demonstrative  pronouns 
are  applied  to  God  as  describing  what  is  understood,  not 
what  is  sensed.  For  we  can  only  describe  Him  as  far  as  we 
vinderstand  Him.  Thus,  according  as  nouns,  participles  and 
demonstrative  pronouns  are  applicable  to  God,  so  far  can 
He  be  signified  by  relative  pronouns.

Second  Article. 

WHETHER  ANY  NAME   CAN   BE   APPLIED  TO   GOdI 
SUBSTANTIALLY  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  no  name  can  be  applied  to 
God  substantially.  For  Damascene  says  {De  Fid.  Orth. 
1.9):  Everything  said  of  God  signifies  not  His  substance,  but 
rather  shows  forth  what  He  is  not ;  or  expresses  some  relation, 
or  something  following  from  His  nature  or  operation. 

Obj.  2.  Further,  Dionysius  says  [Div.  Nom.  i.):  You 
will  find  a  chorus  of  holy  doctors  addressed  to  the  end  of  dis- 
tinguishing clearly  and  praiseworthily  the  divine  processions 
in  the  denominations  of  God.  Thus  the  names  applied  by  the 
holy  doctors  in  praising  God  are  distinguished  according 
to  the  divine  processions  themselves.  But  what  expresses 
the  procession  of  anything,  does  not  signify  its  essence. 
Therefore  the  names  applied  to  God  are  not  said  of  Him 
substantially. 

Obj.  3.  Further,  a  thing  is  named  by  us  according  as 
we  understand  it.  But  God  is  not  understood  by  us  in 
this  life  in  His  substance.  Therefore  neither  is  any  name 
we  can  use  applied  substantially  to  God. 

On  the  contrary,  Augustine  says  (De  Trin.  vi.) :  The  being 
of  God  is  the  being  strong,  or  the  being  wise,  or  whatever  else 
we   may  say  of  that   simplicity  whereby    His    substance   is 
signified. 
Therefore  all  names  of  this  kind  signify  the  divine  substance. 

I  answer  that.  Negative  names  applied  to  God  or  signifying 
His  relation  to  creatures  manifestly  do  not  at  all  signify 
His  substance,  but  rather  express  the  distance  of  the  creature 
from  Him,  or  His  relation  to  something  else,  or  rather,  the 
relation  of  creatures  to  Himself. 

But  as  regards  absolute  and  affirmative  names  of  God,  as 
good,  wise,  and  the  like,  various  and  many  opinions  have 
been  given.  For  some  have  said  that  all  such  names, 
although  they  are  applied  to  God  affirmatively,  nevertheless 


153  THE  NAMES  OF  GOD  Q.  13.  Art.  2 

have  been  brought  into  use  more  to  express  some  remotion 
from  God,  rather  than  to  express  anything  that  exists 
positively  in  Him.  Hence  they  assert  that  when  we  say 
that  God  Hves,  we  mean  that  God  is  not  hke  an  inanimate 
thing;  and  the  same  in  hke  manner  apphes  to  other  names; 
and  this  was  taught  by  Rabbi  Moses.  Others  say  that 
these  names  appHed  to  God  signify  His  relationship  towards 
creatures :  thus  in  the  words,  God  is  good,  we  mean,  God  is 
the  cause  of  goodness  in  things;  and  the  same  rule  applies 
to  other  names. 

Both  of  these  opinions,  however,  seem  to  be  untrue  for 
three  reasons.  First  because  in  neither  of  them  can  a  reason 
be  assigned  why  some  names  more  than  others  are  applied 
to  God.  For  He  is  assuredly  the  cause  of  bodies  in  the  same 
way  as  He  is  the  cause  of  good  things;  therefore  if  the  words 
God  is  good,  signified  no  more  than,  God  is  the  cause  of  good 
things,  it  might  in  like  manner  be  said  that  God  is  a  body, 
inasmuch  as  He  is  the  cause  of  bodies.  So  also  to  say  that 
He  is  a  body  implies  that  He  is  not  a  mere  potentiality,  as 
is  primary  matter.  Secondly,  because  it  would  follow  that 
all  names  applied  to  God  would  be  said  of  Him  by  way  of 
being  taken  in  a  secondary  sense,  as  healthy  is  secondarily 
said  of  medicine,  forasmuch  as  it  signifies  only  the  cause  of 
health  in  the  animal  which  primarily  is  called  healthy. 
Thirdly,  because  this  is  against  the  intention  of  those  who 
speak  of  God.  For  in  saying  that  God  lives,  they  assuredly 
mean  more  than  to  say  that  He  is  the  cause  of  our  life, 
or  that  He  differs  from  inanimate  bodies. 

Therefore  we  must  hold  a  different  doctrine — viz.,  that  f 
these  names  signify  the  divine  substance,  and  are  predicated 
substantially  of  God,  although  they  fall  short  of  a  full  \ 
representation  of  Him.  Which  is  proved  thus.  For  these 
names  express  God,  so  far  as  our  intellects  know  Him.  Now 
since  our  intellect  knows  God  from  creatures,  it  knows  Him 
as  far  as  creatures  represent  Him.  Now  it  was  shown  above 
(Q.  IV.  A.  2)  that  God  prepossesses  in  Himself  all  the 
perfections  of  creatures,  being  Himself  simply  and  univer- 
sally perfect.     Hence  every  creature  represents  Him,  and  is 


Q.  13.  Art.  2     THE  "  SUMMA  THEOLOGICA "  154 

like  Him  so  far  as  it  possesses  some  perfection:  yet  it 
represents  Him  not  as  something  of  the  same  species  or 
genus,  but  as  the  excelling  principle  of  whose  form  the 
effects  fall  short,  although  they  derive  some  kind  of  likeness 
thereto,  even  as  the  forms  of  inferior  bodies  represent  the 
power  of  the  sun.  This  was  explained  above  (Q.  IV.  A.  3.), 
in  treating  of  the  divine  perfection.  Therefore  the  aforesaid 
names  signify  the  divine  substance,  but  in  an  imperfect 
manner,  even  as  creatures  represent  it  imperfectly.  So  when 
we  say,  God  is  good,  the  meaning  is  not,  God  is  the  cause  of 
goodness,  or,  God  is  not  evil ;  but  the  meaning  is.  Whatever  good 
we  attribute  to  creatures,  pre-exists  in  God,  and  in  a  more 
excellent  and  higher  way.  Hence  it  does  not  follow  that 
God  is  good,  because  He  causes  goodness ;  but  rather,  on  the 
contrary.  He  causes  goodness  in  things  because  He  is  good ; 
according  to  what  Augustine  says  (De  Doctr.  Christ,  i.  32), 
Because  He  is  good,  we  are. 

Reply  Obj.  i.  Damascene  says  that  these  names  do  not 
signify  what  God  is,  forasmuch  as  by  none  of  these  names 
is  perfectly  expressed  what  He  is ;  but  each  one  signifies  Him 
in  an  imperfect  manner,  even  as  creatures  represent  Him 
imperfectly. 

Reply  Obj.  2.  In  the  signification  of  names,  that  from  which 
the  name  is  derived  is  different  sometimes  from  what  it  is 
intended  to  signify,  as  for  instance  this  name  stone  {lapis)  is 
imposed  from  the  fact  that  it  hurts  the  foot  (Icedit  pedem), 
but  it  is  not  imposed  to  signify  that  which  hurts  the  foot, 
but  rather  to  signify  a  certain  kind  of  body;  otherwise 
everything  that  hurts  the  foot  would  be  a  stone.*  So  we 
must  say  that  these  kinds  of  divine  names  are  imposed 
from  the  divine  processions;  for  as  according  to  the  diverse 
processions  of  their  perfections,  creatures  are  the  representa- 
tions of  God,  although  in  an  imperfect  manner;  so  likewise 
our  intellect  knows  and  names  God  according  to  each  kind 
of  procession;  but  nevertheless  these  names  are  not  imposed 
to  signify  the  processions  themselves,  as  if  when  we  say  God 

*  This  refers  to  the  Latin  etymology  of  the  word  lapis,  which  has 
no  place  in  English.

lives,  the  sense  were,  life  proceeds  from  Him  ;  but  to  signify 
the  principle  itself  of  things,  in  so  far  as  life  pre-exists 
in  Him,  although  it  pre-exists  in  Him  in  a  more  eminent  way 
than  can  be  understood  or  signified. 

Reply  Obj.  3.  We  cannot  know  the  essence  of  God  in 
this  life,  as  He  really  is  in  Himself;  but  we  know  Him 
accordingly  as  He  is  represented  in  the  perfections  of 
creatures;  and  thus  the  names  imposed  by  us  signify  Him 
in  that  manner  only. 

Third  Article. 

whether  any  name  can  be  applied  to  god  in  its 

literal  sense  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  no  name  is  applied  literally  to 
God.  For  all  names  which  we  apply  to  God  are  taken  from 
creatures;  as  was  explained  above  (A.  i).  But  the  names 
of  creatures  are  applied  to  God  metaphorically,  as  when 
we  say,  God  is  a  stone,  or  a  lion,  or  the  like.  Therefore 
names  are  applied  to  God  in  a  metaphorical  sense. 

Obj.  2.  Further,  no  name  can  be  applied  literally  to  any- 
thing if  it  should  be  withheld  from  it  rather  than  given  to  it. 
But  all  such  names  as  good,  wise,  and  the  like,  are  more 
truly  withheld  from  God  than  given  to  Him;  as  appears 
from  what  Dionysius  says  {Ccel.  Hier.  ii.).  Therefore  none 
of  these  names  belong  to  God  in  their  literal  sense. 

Obj.  3.  Further,  corporeal  names  are  applied  to  God  in 
a  metaphorical  sense  only;  since  He  is  incorporeal.  But  all 
such  names  imply  some  kind  of  corporeal  condition;  for 
their  meaning  is  bound  up  with  time  and  composition  and 
like  corporeal  conditions.  Therefore  all  these  names  are 
applied  to  God  in  a  metaphorical  sense. 

On  the  contrary,  Ambrose  says  (De  Fide  ii.).  Some  names 
there  are  which  express  evidently  the  property  of  the  divinity, 
and  some  which  express  the  clear  truth  of  the  divine  majesty,  but 
others  there  are  which  are  applied  to  God  metaphorically  by 
way  of  similitude.    Therefore  not  all  names  are  applied  to 


Q.  13.  Art.  3   THE  "  SUMMA  THEOLOGICA  "  156 

God  in  a  metaphorical  sense,  but  there  are  some  which  are 
said  of  Him  in  their  literal  sense. 

/  answer  that,  According  to  the  preceding  article,  our 
knowledge  of  God  is  derived  from  the  perfections  which 
flow  from  Him  to  creatures,  which  perfections  are  in  God 
in  a  more  eminent  way  than  in  creatures.  Now  our  intellect 
apprehends  them  as  they  are  in  creatures,  and  as  it 
apprehends  them  it  signifies  them  by  names.  Therefore 
as  to  the  names  applied  to  God,  there  are  two  things  to  be 
considered — viz.,  the  perfections  which  they  signify,  such  as 
goodness,  life,  and  the  like,  and  their  mode  of  signification. 
As  regards  what  is  signified  by  these  names,  they  belong 
properly  to  God,  and  more  properly  than  they  belong  to 
creatures,  and  are  applied  primarily  to  Him.  But  as  regards 
their  mode  of  signification,  they  do  not  properly  and  strictly 
apply  to  God;  for  their  mode  of  signification  applies  to 
creatures. 

Reply  Obj.  i.  There  are  some  names  which  signify  these 
perfections  flowing  from  God  to  creatures  in  such  a  way 
that  the  imperfect  way  in  which  creatures  receive  the  divine 
perfection  is  part  of  the  very  signification  of  the  name 
itself,  as  stone  signifies  a  material  being,  and  names  of  this 
kind  can  be  applied  to  God  only  in  a  metaphorical  sense. 
Other  names,  however,  express  these  perfections  absolutely, 
without  any  such  mode  of  participation  being  part  of  their 
signification,  as  the  words  being,  good,  living,  and  the  like, 
and  such  names  can  be  literally  applied  to  God. 

Reply  Obj.  2.  Such  names  as  these,  as  Dionysius  shows, 
are  denied  of  God  for  the  reason  that  what  the  name  signifies 
does  not  belong  to  Him  in  the  ordinary  sense  of  its  signi- 
fication, but  in  a  more  eminent  way.  Hence  Dionysius 
says  also  that  God  is  above  all  substance  and  all  life. 

Reply  Obj.  3.  These  names  which  are  applied  to  God 
literally  imply  corporeal  conditions  not  in  the  thing  signi- 
fied, but  as  regards  their  mode  of  signification:  whereas 
those  which  are  applied  to  God  metaphorically  imply  and 
mean  a  corporeal  condition  in  the  thing  signified. 


157  THE  NAMES  OF  GOD  Q.  13.  Art.  4 

Fourth  Article, 
whether  names  applied  to  god  are  synonymous? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  these  names  applied  to  God 
are  synonymous  names.  For  synonymous  names  are  those 
which  mean  exactly  the  same.  But  these  names  applied  to 
God  mean  entirely  the  same  thing  in  God ;  for  the  goodness 
of  God  is  His  essence,  and  likewise  it  is  His  wisdom. 
Therefore  these  names  are  entirely  synonymous. 

Ohj.  2.  Further,  if  it  be  said  these  names  signify  one  and 
the  same  thing  in  reality,  but  differ  in  idea,  it  can  be  objected 
that  an  idea  to  which  no  reality  corresponds  is  a  vain  notion. 
Therefore  if  these  ideas  are  many,  and  the  thing  is  one,  it 
seems  also  that  all  these  ideas  are  vain  notions. 

Ohj.  3.  Further,  a  thing  which  is  one  in  reality  and  in 
idea,  is  more  one  than  what  is  one  in  reality  and  many  in 
idea.  But  God  is  supremely  one.  Therefore  it  seems  that 
He  is  not  one  in  reality  and  many  in  idea;  and  thus  the 
names  applied  to  God  do  not  signify  different  ideas;  and 
thus  they  are  synonymous. 

On  the  contrary,  All  synonyms  united  with  each  other 
are  redundant,  as  when  we  say,  vesture  clothing.  Therefore 
if  all  names  applied  to  God  are  synonymous,  we  cannot 
properly  say  good  God,  or  the  like,  and  yet  it  is  written, 
0  most  mighty,  great  and  powerful,  the  Lord  of  hosts  is  Thy 
name  ( J  er.  xxxii.  18) . 

/  answer  that,  These  names  spoken  of  God  are  not  synony- 
mous. This  would  be  easy  to  understand,  if  we  said  that 
these  names  are  used  to  remove,  or  to  express  the  relation  of 
cause  to  creatures;  for  thus  it  would  follow  that  there  are 
different  ideas  as  regards  the  diverse  things  denied  of  God, 
or  as  regards  diverse  effects  connoted.  But  even  accord- 
ing to  what  was  said  above  (A.  2),  that  these  names  signify  the 
divine  substance,  although  in  an  imperfect  manner,  it  is 
also  clear  from  what  has  been  said  (AA.  i,  2)  that  they  have 
diverse  meanings.  For  the  idea  signified  by  the  name  is  the 
conception  in  the  intellect  of  the  thing  signified  by  the  name. 


Q.  13.  Art.  5   THE  ''  SUMMA  THEOLOGICA  "  158 

But  our  intellect,  since  it  knows  God  from  creatures,  in  order 
to  understand  God,  forms  conceptions  proportional  to  the 
perfections  flowing  from  God  to  creatures,  which  perfec- 
tions pre-exist  in  God  unitedly  and  simply,  whereas  in 
creatures  they  are  received,  divided  and  multiplied.  As, 
therefore,  to  the  different  perfections  of  creatures  there 
corresponds  one  simple  principle  represented  by  different 
perfections  of  creatures  in  a  various  and  manifold  manner, 
so  also  to  the  various  and  multiplied  conceptions  of  our 
intellect  there  corresponds  one  altogether  simple  principle, 
according  to  these  conceptions,  imperfectly  understood. 
Therefore,  although  the  names  applied  to  God  signify  one 
thing,  still  because  they  signify  that  thing  under  many  and 
different  aspects,  they  are  not  synonymous. 

Thus  appears  the  solution  of  the  First  Objection,  since 
synonymous  terms  signify  one  thing  under  one  aspect;  for 
words  which  signify  different  aspects  of  one  thing,  do  not 
signify  primarily  and  absolutely  one  thing;  because  the 
term  only  signifies  the  thing  through  the  medium  of  the 
intellectual  conception,  as  was  said  above. 

Reply  Ohj.  2.  The  many  aspects  of  these  names  are  not 
empty  and  vain,  for  there  corresponds  to  all  of  them 
one  simple  reality  represented  by  them  in  a  manifold  and 
imperfect  manner. 

Reply  Ohj.  3.  The  perfect  unity  of  God  requires  that 
what  are  manifold  and  divided  in  others  should  exist  in  Him 
simply  and  unitedly.  Thus  it  comes  about  that  He  is  one 
in  reality,  and  yet  multiple  in  idea,  because  our  intellect 
apprehends  Him  in  a  manifold  manner,  as  things  represent 
Him. 

Fifth  Article. 

whether  what  is  said  of  god  and  of  creatures  is 
univocally  predicated  of  them  1 

We  proceed  thus  to  the  Fifth  Article  : — 

Objection  i.  It  seems  that  the  things  attributed  to  God 
and  creatures  are  uni vocal.  For  every  equivocal  term  is 
reduced  to  the  univocal,  as  many  are  reduced  to  one :  for  if 


159  THE  NAMES  OF  GOD  Q.  13.  Art.  5 

the  name  dog  be  said  equivocally  of  the  barking  dog,  and 
of  the  dogfish,  it  must  be  said  of  some  uni vocally — viz., 
of  all  barking  dogs;  otherwise  we  proceed  to  infinitude. 
Now  there  are  some  univocal  agents  which  agree  with  their 
effects  in  name  and  definition,  as  man  generates  man;  and 
there  are  some  agents  which  are  equivocal,  as  the  sun 
which  causes  heat,  although  the  sun  is  hot  only  in  an 
equivocal  sense.  Therefore  it  seems  that  the  first  agent  to 
which  all  other  agents  are  reduced,  is  an  univocal  agent: 
and  thus  what  is  said  of  God  and  creatures,  is  predicated 
univocally. 

Obj.  2.  Further,  there  is  no  similitude  among  equivocal 
things.  Therefore  as  creatures  have  a  certain  likeness  to 
God,  according  to  the  word  of  Genesis  (i.  26),  Let  us  make 
man  to  our  image  and  likeness,  it  seems  that  something  can 
be  said  of  God  and  creatures  univocally. 

Obj.  3.  Further,  measure  is  homogeneous  with  the  thing 
measured.  But  God  is  the  first  measure  of  all  beings. 
Therefore  God  is  homogeneous  with  creatures;  and  thus  a 
word  may  be  applied  univocally  to  God  and  to  creatures. 

On  the  contrary,  Whatever  is  predicated  of  various  things 
under  the  same  name  but  not  in, the  same  sense,  is  predicated 
equivocally.  But  no  name  belongs  to  God  in  the  same 
sense  that  it  belongs  to  creatures;  for  instance,  wisdom 
in  creatures  is  a  quality,  but  not  in  God,  Now  a  different 
genus  changes  an  essence,  since  the  genus  is  part  of  the 
definition ;  and  the  same  applies  to  other  things.  Therefore 
whatever  is  said  of  God  and  of  creatures  is  predicated 
equivocally. 

Further,  God  is  more  distant  from  creatures  than  any 
creatures  are  from  each  other.  But  the  distance  of  some 
creatures  makes  any  univocal  predication  of  them  im- 
possible, as  in  the  case  of  those  things  which  are  not  in  the 
same  genus.  Therefore  much  less  can  anything  be  predicated 
univocally  of  God  and  creatures;  and  so  only  equivocal 
predication  can  be  applied  to  them. 

/  answer  that,  Univocal  predication  is  impossible  between 
God  and  creatures.     The  reason  of  this  is  that  every  effect 


Q.  13.  Art.  5   THE  "  SUMMA  THEOLOGICA  "  160 

which  is  not  an  adequate  result  of  the  power  of  the  efficient 

cause,  receives  the  simihtude  of  the  agent  not  in  its  full 

degree,  but  in  a  measure  that  falls  short,  so  that  what  is 

divided  and  multiplied  in  the  effects  resides  in  the  agent 

simply,  and  in  the  same  manner;  as  for  example  the  sun 

by  the  exercise  of  its  one  power  produces  manifold  and 

various  forms  in  all  inferior  things.     In  the  same  way,  as 

said  in  the  preceding  article,   all  perfections  existing  in 

creatures  divided  and  multiplied,  pre-exist  in  God  unitedly. 

Thus,  when  any  term  expressing  perfection  is  applied  to  a 

creature,  it  signifies  that  perfection  distinct  in  idea  from 

other  perfections ;  as,  for  instance,  by  this  term  wise  applied 

to  a  man,  we  signify  some  perfection  distinct  from  a  man's 

essence,  and  distinct  from  his  power  and  existence,  and  from 

all  similar  things;  whereas  when  we  apply  it  to  God,  we  do 

not  mean  to  signify  anything  distinct  from  His  essence,  or 

power,  or  existence.     Thus  also  this  term  wise  applied  to 

man  in  some  degree  circumscribes  and  comprehends  the 

thing  signified ;  whereas  this  is  not  the  case  when  it  is  applied 

to  God ;  but  it  leaves  the  thing  signified  as  incomprehended, 

and  as  exceeding  the  signification  of  the  name.     Hence  it  is 

evident  that  this  term  wise  is  not  applied  in  the  same  way 

to  God  and  to  man.     The  same  rule  applies  to  other  terms. 

Hence  no  name  is  predicated  uni vocally  of  God  and  of 

creatures. 

Neither,  on  the  other  hand,  are  names  applied  to  God 
and  creatures  in  a  purely  equivocal  sense,  as  some  have 
said.  Because  if  that  were  so,  it  follows  that  from  creatures 
nothing  could  be  known  or  demonstrated  about  God  at  all; 
for  the  reasoning  would  always  be  exposed  to  the  fallacy  of 
equivocation.  Such  a  view  is  against  the  philosophers,  who 
proved  many  things  about  God,  and  also  against  what  the 
Apostle  says:  The  invisible  things  of  God  are  clearly  seen 
being  understood  by  the  things  that  are  made  (Rom.  i.  20). 
Therefore  it  must  be  said  that  these  names  are  said  of  God 
and  creatures  in  an  analogous  sense,  that  is,  according  to 
proportion. 

Now  names  are  thus  used  in  two  ways :  either  according 


i6i  THE  NAMES  OF  GOD  Q.  13.  Art.  5 

as  many  things  are  proportionate  to  one,  thus  for  example 
healthy  is  predicated  of  medicine  and  urine  in  relation  and 
in  proportion  to  health  of  body,  of  which  the  former  is  the 
sign  and  the  latter  the  cause:  or  according  as  one  thing  is 
proportionate  to  another,  thus  healthy  is  said  of  medicine 
and  animal,  since  medicine  is  the  cause  of  health  in  the 
animal  body.  And  in  this  way  some  things  are  said  of  God 
and  creatures  analogically,  and  not  in  a  purely  equivocal  nor 
in  a  purely  uni vocal  sense.  For  we  can  name  God  only 
from  creatures  (A.  i).  Thus,  whatever  is  said  of  God  and 
creatures,  is  said  according  to  the  relation  of  a  creature  to 
God  as  its  principle  and  cause,  wherein  all  perfections  of  things 
pre-exist  excellently.  Now  this  mode  of  community  of  idea 
is  a  mean  between  pure  equivocation  and  simple  univoca- 
tion.  For  in  analogies  the  idea  is  not,  as  it  is  in  univocals, 
one  and  the  same,  yet  it  is  not  totally  diverse  as  in  equi- 
vocals;  but  a  term  which  is  thus  used  in  a  multiple  sense 
signifies  various  proportions  to  some  one  thing ;  thus  healthy 
applied  to  urine  signifies  the  sign  of  animal  health,  and 
applied  to  medicine  signifies  the  cause  of  the  same  health. 

Reply  Ohj.  i.  Although  equivocal  predications  must  be 
reduced  to  univocal,  still  in  actions  the  non-univocal  agent 
must  precede  the  univocal  agent.  For  the  non-univocal 
agent  is  the  universal  cause  of  the  whole  species,  as  for 
instance  the  sun  is  the  cause  of  the  generation  of  all  men; 
whereas  the  univocal  agent  is  not  the  universal  efficient 
cause  of  the  whole  species  (otherwise  it  would  be  the  cause 
of  itself,  since  it  is  contained  in  the  species),  but  is  a  particular 
cause  of  this  individual  which  it  places  under  the  species 
by  way  of  participation.  Therefore  the  universal  cause  of 
the  whole  species  is  not  an  univocal  agent :  and  the  universal 
cause  comes  before  the  particular  cause.  But  this  universal 
agent,  whilst  it  is  not  univocal,  nevertheless  is  not  altogether 
equivocal,  otherwise  it  could  not  produce  its  own  likeness, 
but  rather  it  is  to  be  called  an  analogical  agent,  as  all  univocal 
predications  are  reduced  to  one  first  non-univocal  analogical 
predication,  which  is  being.

imperfect,  for  it  does  not  represent  one  and  the  same  generic 
thing  (Q.  IV.  A.  3). 

Reply  Obj.  3.  God  is  not  the  measure  proportioned  to 
things  measured;  hence  it  is  not  necessary  that  God  and 
creatures  should  be  in  the  same  genus. 

The  arguments  adduced  in  the  contrary  sense  prove 
indeed  that  these  names  are  not  predicated  uni vocally  of 
God  and  creatures;  yet  they  do  not  prove  that  they  are 
predicated  equivocally. 

Sixth  Article. 

whether  names  predicated  of  god  are  predicated 
primarily  of  creatures  ? 

We  proceed  thus  to  the  Sixth  Article  : — • 

Objection  i.  It  seems  that  names  are  predicated  primarily 
of  creatures  rather  than  of  God.  For  we  name  anything 
accordingly  as  we  know  it,  since  names,  as  the  Philosopher 
says,  are  signs  of  ideas.  But  we  know  creatures  before  we 
know  God.  Therefore  the  names  imposed  by  us  are  pre- 
dicated primarily  of  creatures  rather  than  of  God. 

Obj.  2.  Further,  Dionysius  says  {Div.  Nom.  i.):  We  name 
God  from  creatures.  But  names  transferred  from  creatures 
to  God,  are  said  primarily  of  creatures  rather  than  of  God, 
as  lion,  stone,  and  the  like.  Therefore  all  names  applied  to 
God  and  creatures  are  applied  primarily  to  creatures  rather 
than  to  God. 

Obj.  3.  Further,  all  names  equally  applied  to  God  and 
creatures,  are  applied  to  God  as  the  cause  of  all  creatures, 
as  Dionysius  says  {De  Myst.  Theol.).  But  what  is  applied 
to  anything  through  its  cause,  is  applied  to  it  secondarily; 
for  healthy  is  primarily  predicated  of  animal  rather  than  of 
medicine,  which  is  the  cause  of  health.  Therefore  these 
names  are  said  primarily  of  creatures  rather  than  of  God. 

On  the  contrary,  It  is  written,  /  bow  my  knees  to  the  Father 
of  our  Lord  Jesus  Christ,  of  Whom  all  paternity  in  heaven  and 
earth  is  named  (Eph.  iii.  14,  15) ;  and  the  same  applies  to  the 
other  names  applied  to  God  and  creatures.  Therefore  these 
names  are  applied  primarily  to  God  rather  than  to  creatures. 


i63  THE  NAMES  OF  GOD  Q.  13.  Art.  6 

/  answer  that,  In  names  predicated  of  many  in  an  analogical 
sense,  all  are  predicated  because  they  have  reference  to 
some  one  thing;  and  this  one  thing  must  be  placed  in  the 
definition  of  them  all.  And  since  that  expressed  by  the  name 
is  the  definition,  as  the  Philosopher  says  {Metaph.  iv.),  such  a 
name  must  be  applied  primarily  to  that  which  is  put  in  the 
definition  of  such  other  things,  and  secondarily  to  these  others 
according  as  they  approach  more  or  less  to  that  first  Thus, 
for  instance,  healthy  applied  to  animals  comes  into  the  defini- 
tion of  healthy  applied  to  medicine,  which  is  called  healthy 
as  being  the  cause  of  health  in  the  animal ;  and  also  into  the 
definition  of  healthy  which  is  applied  to  urine,  which  is  called 
healthy  in  so  far  as  it  is  the  sign  of  the  animal's  health. 
Thus,  all  names  applied  metaphorically  to  God,  are  applied 
to  creatures  primarily  rather  than  to  God,  because  when  said 
of  God  they  mean  only  similitudes  to  such  creatures.  For 
as  smiling  applied  to  a  field  means  only  that  the  field  in  the 
beauty  of  its  flowering  is  like  to  the  beauty  of  the  human 
smile  by  proportionate  likeness,  so  the  name  of  lion  applied 
to  God  means  only  that  God  manifests  strength  in  His 
works,  as  a  lion  in  his.  Thus  it  is  clear  that  applied  to 
God  the  signification  of  names  can  be  defined  only  from  what 
is  said  of  creatures.  But  to  other  names  not  applied  to 
God  in  a  metaphorical  sense,  the  same  rule  would  apply  if 
they  were  spoken  of  God  as  the  cause  only,  as  some  have 
supposed.  For  when  it  is  said,  God  is  good,  it  would  then  only 
mean,  God  is  the  cause  of  the  creature'' s  goodness  ;  thus  the 
term  good  applied  to  God  would  include  in  its  meaning  the 
creature's  goodness.  Hence  good  would  apply  primarily  to 
creatures  rather  than  God.  But  as  was  shown  above  (A.  2), 
these  names  are  applied  to  God  not  as  the  cause  only,  but 
also  essentially.  For  the  words,  God  is  good,  or  wise,  signify 
not  only  that  He  is  the  cause  of  wisdom  or  goodness,  but  that 
these  exist  in  Him  in  a  more  excellent  way.  Hence  as  regards 
what  the  name  signifies,  these  names  are  applied  primarily 
to  God  rather  than  to  creatures,  because  these  perfections 
flow  from  God  to  creatures ;  but  as  regards  the  imposition 
of  the  names,  they  are  primarily  applied  by  us  to  creatures 


Q.  13.  Art.  7    THE  "  SUMMA  THEOLOGICA  "  164 

which  we  know  first .  Hence  they  have  a  mode  of  significa- 
tion wliich  belongs  to  creatures,  as  said  above  (A.  3). 

Reply  Ohj.  i.  This  objection  refers  to  the  imposition  of 
the  name. 

Reply  Ohj.  2.  The  same  rule  does  not  apply  to  meta- 
phorical and  to  other  names,  as  said  above. 

Reply  Ohj.  3.  This  objection  would  be  valid  if  these  names 
were  applied  to  God  only  as  cause,  and  not  also  essentially, 
for  instance  as  healthy  is  applied  to  medicine. 

Seventh  Article. 

whether  names  which  imply  relation  to  creatures 
are  predicated  of  god  temporally  ? 

We  proceed  thus  to  the  Seventh  Article  : — 

Ohjection  i.  It  seems  that  names  which  imply  i  elation 
to  creatures  are  not  predicated  of  God  temporally.  For  all 
such  names  signify  the  divine  substance,  as  is  universally  held. 
Hence  also  Ambrose  says  {De  Fide  i.)  that  this  name  Lord 
is  a  name  of  power,  which  is  the  divine  substance ;  and  Creator 
signifies  the  action  of  God,  which  is  His  essence.  Now  the 
divine  substance  is  not  temporal,  but  eternal.  Therefore 
these  names  are  not  applied  to  God  temporally,  but  eternally. 

Oh^j.  2.  Further,  that  to  which  something  applies  tempor- 
ally can  be  described  as  made ;  for  what  is  white  temporally 
is  made  white.  But  to  be  made  does  not  apply  to  God. 
Therefore  nothing  can  be  predicated  of  God  temporally. 

Ohj.  3.  Further,  if  any  names  are  applied  to  God  tem- 
porally as  implying  relation  to  creatures,  the  same  rule 
holds  good  of  all  things  that  imply  relation  to  creatures. 
Bot  some  names  are  spoken  of  God  implying  relation  of 
God  to  creatures  from  eternity;  for  from  eternity  He  knew 
and  loved  the  creature,  according  to  the  word  .*  /  have  loved 
thee  with  an  everlasting  love  (Jer.  xxxi.  3).  Therefore  also 
other  names  implying  relation  to  creatures,  as  Lord  and 
Creator,  are  applied  to  God  from  eternity. 

Ohj.  4.  Further,  names  of  this  kind  signify  relation. 
Therefore  that  relation  must  be  something  in  God,  or  in  the 


i65  THE  NAMES  OF  GOD  Q.  13.  Art.  7 

creature  only.  But  it  cannot  be  that  it  is  something  in  the 
creature  only,  for  in  that  case  God  would  be  called  Lord 
from  the  opposite  relation  which  is  in  creatures ;  and  nothing 
is  named  from  its  opposite.  Therefore  the  relation  must  be 
something  in  God  also.  But  nothing  temporal  can  be  in  God, 
for  He  is  above  time.  Therefore  these  names  are  not  applied 
to  God  temporally. 

Ohj.  5.  Further,  a  thing  is  called  relative  from  relation; 
for  instance  lord  from  lordship,  as  white  from  whiteness. 
Therefore  if  the  relation  of  lordship  is  not  really  in  God, 
but  only  in  idea,  it  follows  that  God  is  not  really  Lord, 
which  is  plainly  false. 

Ohj.  6.  Further,  in  relative  things  which  are  not  simul- 
taneous in  nature,  one  can  exist  without  the  other;  as  a 
thing  knowable  can  exist  without  the  knowledge  of  it,  as 
the  Philosopher  says  (Prcedic.  v.).  But  relative  things 
which  are  said  of  God  and  creatures  are  not  simultaneous  in 
nature.  Therefore  a  relation  can  be  predicated  of  God  to  the 
creature  even  without  the  existence  of  the  creature;  and 
thus  these  names.  Lord  and  Creator,  are  predicated  of  God 
from  eternity,  and  not  temporally. 

On  the  contrary,  Augustine  says  (De  Trin.  v.),  that  this 
relative  appellation  Lord  is  applied  to  God  temporally. 

I  answer  that,  The  names  which  import  relation  to  creatures 
are  applied  to  God  temporally,  and  not  from  eternity. 

To  see  this  we  must  learn  that  some  have  said  that  relation 
is  not  a  reality,  but  only  an  idea.  But  this  is  plainly  seen 
to  be  false  from  the  very  fact  that  things  themselves  have 
a  mutual  natural  order  and  habitude.  Nevertheless  it  is 
necessary  to  know  that  since  relation  has  two  extremes,  it 
happens  in  three  ways  that  a  relation  is  real  or  logical. 
Sometimes  from  both  extremes  it  is  an  idea  only,  as  when 
mutual  order  or  habitude  can  only  be  between  things  in  the 
apprehension  of  reason;  as  when  we  say  a  thing  the  same 
as  itself.  For  reason  apprehending  one  thing  twice  regards 
it  as  two;  thus  it  apprehends  a  certain  habitude  of  a  thing 
to  itself.  And  the  same  applies  to  relations  between  being 
and  non-being  formed  by  reason,  apprehending  non-being  as 


Q.  13.  Art.  7    THE  "  SUMMA  THEOLOGICA  "  166 

an  extreme.     The  same  is  true  of  relations  that  follow  upon 
an  act  of  reason,  as  genus  and  species,  and  the  like. 

Now  there  are  other  relations  which  are  realities  as  regards 
both  extremes,  as  when  for  instance  a  habitude  exists  be- 
tween two  things  according  to  some  reality  that  belongs  to 
both ;  as  is  clear  of  all  relations  consequent  upon  quantity ; 
as  great  and  small,  double  and  half,  and  the  like ;  for  quantity 
exists  in  both  extremes:  and  the  same  applies  to  relations 
consequent  upon  action  and  passion,  as  motive  power  and 
the  movable  thing,  father  and  son,  and  the  like. 

Again,  sometimes  a  relation  in  one  extreme  may  be  a 
reality,  while  in  the  other  extreme  it  is  an  idea  only:  and 
this  happens  whenever  two  extremes  are  not  of  one  order; 
as  sense  and  science  refer  respectively  to  sensible  things  and 
to  intellectual  things;  which,  inasmuch  as  they  are  realities 
existing  in  nature,  are  outside  the  order  of  sensible  and  in- 
telligible existence.  Therefore  in  science  and  in  sense  a  real 
relation  exists,  because  they  are  ordered  either  to  the  know- 
ledge or  to  the  sensible  perception  of  things;  whereas  the 
things  looked  at  in  themselves  are  outside  this  order,  and 
hence  in  them  there  is  no  real  relation  to  science  and  sense, 
but  only  in  idea,  inasmuch  as  the  intellect  apprehends  them 
as  terms  of  the  relations  of  science  and  sense.  Hence,  the 
Philosopher  says  (Metaph.  v.)  that  they  are  called  relative, 
not  forasmuch  as  they  are  related  to  other  things,  but  as 
others  are  related  to  them.  Likewise  for  instance,  on  the 
right  is  not  applied  to  a  column,  unless  it  stands  as  regards  an 
animal  on  the  right  side ;  which  relation  is  not  really  in  the 
column,  but  in  the  animal. 

Since  therefore  God  is  outside  the  whole  order  of  creation, 
and  all  creatures  are  ordered  to  Him,  and  not  conversely, 
it  is  manifest  that  creatures  are  really  related  to  God  Himself ; 
whereas  in  God  there  is  no  real  relation  to  creatures,  but  a 
relation  only  in  idea,  inasmuch  as  creatures  are  referred  to 
Him.  Thus  there  is  nothing  to  prevent  these  names  which 
import  relation  to  the  creature  from  being  predicated  of  God 
temporally,  not  by  reason  of  any  change  in  Him,  but  by 
reason  of  the  change  of  the  creature;  as  a  column  is  on  the 


i67  THE  NAMES  OF  GOD  Q.  13.  Art.  7 

right  of  an  animal,  without  change  in  itself,  but  by  change 
in  the  animal. 

Reply  Ohj.  i.  Some  relative  names  are  imposed  to  signify 
the  relative  habitudes  themselves,  as  master  and  servant, 
father  and  son,  and  the  like,  and  these  relatives  are  called 
predicamental  {secundum  esse).  But  others  are  imposed  to 
signify  the  things  from  which  ensue  certain  habitudes,  as 
the  mover  and  the  thing  moved,  the  head  and  the  thing  that 
has  a  head,  and  the  like:  and  these  relatives  are  called 
transcendental  [secundum  did).  Thus,  there  is  the  same 
twofold  difference  in  divine  names.  For  some  signify  the 
habitude  itself  to  the  creature,  as  Lord,  and  these  do  not 
signify  the  divine  substance  directly,  but  indirectly,  in  so 
far  as  they  presuppose  the  divine  substance;  as  dominion 
presupposes  power,  which  is  the  divine  substance.  Others 
signify  the  divine  essence  directly,  and  consequently  the 
corresponding  habitudes,  as  Savioiir,  Creator,  and  such-like ; 
and  these  signify  the  action  of  God,  which  is  His  essence. 
Yet  both  names  are  said  of  God  temporally  so  far  as  they 
imply  a  habitude  either  principally  or  consequently,  but 
not  as  signifying  the  essence,  either  directly  or  indirectly. 

Reply  Ohj.  2.  As  relations  applied  to  God  temporally  are 
only  in  God  in  our  idea,  so,  to  become,  or  to  he  made  are 
applied  to  God  only  in  idea,  with  no  change  in  Him,  as  for 
instance  when  we  say.  Lord,  Thou  art  become  [Douay,  hast 
been]  our  refuge  (Ps.  Ixxxix.  i). 

Reply  Ohj.  3.  The  operation  of  the  intellect  and  will  is 
in  the  operator,  therefore  names  signifying  relations  follow- 
ing upon  the  action  of  the  intellect  or  will,  are  applied  to 
God  from  eternity ;  whereas  those  following  upon  the  actions 
proceeding  according  to  our  mode  of  thinking  to  external 
effects  are  applied  to  God  temporally,  as  Saviour,  Creator, 
and  the  like. 

Reply  Ohj.  4.  Relations  signified  by  these  names  which 
are  applied  to  God  temporally,  are  in  God  only  in  idea ;  but 
the  opposite  relations  in  creatures  are  real.  Nor  is  it  in- 
congruous that  God  should  be  denominated  from  relations 
really   existing    in   the    thing,    yet    so   that    the   opposite 


Q.  13.  Art.  8    THE  "  SUMMA  THEOLOGICA  "  168 

relations  in  God  should  also  be  understood  by  us  at  the 
same  time;  in  the  sense  that  God  is  spoken  of  relatively  to 
the  creature,  inasmuch  as  the  creature  is  related  to  Him :  thus 
the  Philosopher  says  (Metaph.  v.)  that  the  object  is  said  to 
be  knowable  relatively  because  knowledge  relates  to  it. 

Reply  Obj.  5.  Since  God  is  related  to  the  creature  for  the 
reason  that  the  creature  is  related  to  Him:  and  since  the 
relation  of  subjection  is  real  in  the  creature,  it  follows  that 
God  is  Lord  not  in  idea  only,  but  in  reality;  for  He  is 
called  Lord  according  to  the  manner  in  which  the  creature 
is  subject  to  Him. 

Reply  Obj.  6.  To  know  whether  relations  are  simultaneous 
by  nature  or  otherwise,  it  is  not  necessary  to  consider  the 
order  of  things  to  which  they  belong  but  the  meaning  of  the 
relations  themselves.  For  if  one  in  its  idea  includes  another, 
and  vice  versa,  then  they  are  simultaneous  by  nature:  as 
double  and  half,  father  and  son,  and  the  like.  But  if  one  in 
its  idea  includes  another,  and  not  vice  versa,  they  are  not 
simultaneous  by  nature.  This  appHes  to  science  and  its 
object;  for  the  object  knowable  is  considered  as  a  poten- 
tiality, and  the  science  as  a  habit,  or  as  an  act.  Hence  the 
knowable  object  in  its  mode  of  signification  exists  before 
science,  but  if  the  same  object  is  considered  in  act,  then  it  is 
simultaneous  with  science  in  act;  for  the  object  known  is 
nothing  as  such  unless  it  is  known.  Thus,  though  God  is 
prior  to  the  creature,  still  because  the  signification  of  Lord 
includes  the  idea  of  a  servant  and  vice  versa,  these  two 
relative  terms.  Lord  and  servant,  are  simultaneous  by 
nature.  Hence  God  was  not  Lord  until  He  had  a  creature 
subject  to  Himself. 

Eighth  Article, 
whether  this  name  god  is  a  name  of  the  nature  ? 

We  proceed  thus  to  the  Eighth  Article: — 

Objection  i.  It  seems  that  this  name,  God,  is  not  a  name 
of  the  nature.  For  Damascene  says  (De  Fid.  Orth.  i.)  that 
God  (@eo?)  is  so  called  from  OeeXv  which  means  to  take  care 


169  THE  NAMES  OF  GOD  Q.  13.  Art.  8 

of,  and  to  cherish  all  things;  or  from  aXOeiv,  that  is,  to  burn, 
for  our  God  is  a  fire  consuming  all  malice;  or  from  OeacrOatt 
which  means  to  consider  all  things.  But  all  these  names 
belong  to  operation.  Therefore  this  name  God  signifies  His 
operation  and  not  His  nature. 

Obj.  2.  Further,  a  thing  is  named  by  us  as  we  know  it. 
But  the  divine  nature  is  unknown  to  us.  Therefore  this 
name  God  does  not  signify  the  divine  nature. 

On  the  contrary,  Ambrose  says  (De  Fide  i.)  that  God  is  a 
name  of  the  nature. 

/  answer  that,  Whence  a  name  is  imposed,  and  what  the 
name  signifies  are  not  always  the  same  thing.  For  as  we 
know  substance  from  its  properties  and  operations,  so  we 
name  substance  sometimes  from  its  operation,  or  its  property : 
e.g.,  we  name  the  substance  of  a  stone  from  its  act,  as  for 
instance  that  it  hurts  the  foot  {Icedit  pedem) ;  but  still  this 
name  is  not  meant  to  signify  the  particular  action,  but  the 
stone's  substance.  The  things,  on  the  other  hand,  known  to 
us  in  themselves,  such  as  heat,  cold,  whiteness,  and  the  like, 
are  not  named  from  other  things.  Hence  as  regards  such 
things  the  meaning  of  the  name  and  its  source  are  the  same. 

Because  therefore  God  is  not  known  to  us  in  His  nature, 
but  is  made  known  to  us  from  His  operations  or  effects,  we 
can  name  Him  from  these,  as  said  in  A.  i;  hence  this  name 
God  is  a  name  of  operation  so  far  as  relates  to  the  source  of 
its  meaning.  For  this  name  is  imposed  from  His  universal 
providence  over  all  things ;  since  all  who  speak  of  God  intend 
to  name  God  as  exercising  providence  over  all:  hence  Dio- 
nysius  says  (Div.  Nom.  xii.),  The  Deity  watches  over  all  with 
perfect  providence  and  goodness.  But  taken  from  this  opera- 
tion, this  name  God  is  imposed  to  signify  the  divine  nature. 

Reply  Obj.  1.  All  that  Damascene  says  refers  to  providence; 
which  is  the  source  of  the  signification  of  the  name  God. 

Reply  Obj.  2.  We  can  name  a  thing  according  to  the 
knowledge  we  have  of  its  nature  from  its  properties  and 
effects.  Hence  because  we  can  know  what  stone  is  in  itself 
from  its  property,  this  name  stone  signifies  the  nature  of 
stone  in  itself;  for  it  signifies  the  definition  of  stone,  by 


Q.  13.  Art.  9   THE  "  SUMMA  THEOLOGICA  "  170 

which  we  know  what  it  is,  for  the  idea  which  the  name 
signifies  is  the  definition,  as  is  said  in  Mefaph.  iv.  Now 
from  the  divine  effects  we  cannot  know  the  divine  nature 
in  itself,  so  as  to  know  what  it  is;  but  only  by  way  of  emi- 
nence, and  by  way  of  causality,  and  of  negation  as  stated 
above  (Q.  XII.  A.  12).  Thus  the  name  God  signifies  the 
divine  nature,  for  this  name  was  imposed  to  signify  some- 
thing existing  above  all  things,  the  principle  of  all  things, 
and  removed  from  all  things;  for  those  who  name  God 
intend  to  signify  all  this. 

Ninth  Article, 
whether  this  name  god  is  communicable  ? 

We  proceed  thus  to  the  Ninth  Article: — 

Objection  i.  It  seems  that  this  name  God  is  communicable. 
For  whosoever  shares  in  the  thing  signified  by  a  name 
shares  in  the  name  itself.  But  this  name  God  signifies  the 
divine  nature,  which  is  communicable  to  others,  according  to 
the  words,  He  hath  given  us  great  [Vulg.,  most  great]  and 
precious  promises,  that  by  these  we  [Vulg.,  ye]  may  be  made 
partakers  of  the  divine  nature  (2  Pet.  i.  4).  Therefore  this 
name  God  can  be  communicated  to  others. 

Obj.  2.  Further,  only  proper  names  are  not  communicable. 
Now  this  name  God  is  not  a  proper,  but  an  appellative  noun ; 
which  appears  from  the  fact  that  it  has  a  plural,  according 
to  the  text,  /  have  said,  You  are  gods  (Ps.  Ixxxi.  6).  There- 
fore this  name  God  is  communicable. 

Obj.  3.  Further,  this  name  God  comes  from  operation,  as 
explained.  But  other  names  given  to  God  from  His  opera- 
tions or  effects  are  communicable;  as  good,  wise,  and  the  like. 
Therefore  this  name  God  is  communicable. 

On  the  contrary,  It  is  written:  They  gave  the  incommunic- 
able name  to  wood  and  stones  (Wis.  xiv.  21),  in  reference  to  the 
divine  name.     Therefore  this  name  God  is  incommunicable. 

I  answer  that,  A  name  is  communicable  in  two  ways, 
properly,  and  by  similitude.  It  is  properly  communicable 
in    the  sense  that  its  whole  signification  can  be  given  to 


171  THE  NAMES  OF  GOD  Q.  13.  Art.  9 

many;  by  similitude  it  is  communicable  according  to  some 
part  of  the  signification  of  the  name.  For  instance  this 
name  lion  is  properly  communicated  to  all  things  of  the 
same  nature  as  lion;  by  similitude  it  is  communicable  to 
those  who  participate  in  the  nature  of  a  lion,  as  for  instance 
by  courage,  or  strength,  and  those  who  thus  participate 
are  called  lions  metaphorically.  To  know,  however,  what 
names  are  properly  communicable,  we  must  consider  that 
every  form  existing  in  the  singular  subject,  by  which  it  is 
individualized,  is  common  to  many  either  in  reality,  or  in 
idea;  as  human  nature  is  common  to  many  in  reality,  and 
in  idea;  whereas  the  nature  of  the  sun  is  not  common  to 
many  in  reality,  but  only  in  idea ;  for  the  nature  of  the  sun 
can  be  understood  as  existing  in  many  subjects;  and  the 
reason  is  because  the  mind  understands  the  nature  of  every 
species  by  abstraction  from  the  singular.  Hence  to  be  in 
one  singular  subject  or  in  many  is  outside  the  idea  of  the 
nature  of  the  species.  So,  given  the  idea  of  a  species,  it 
can  be  understood  as  existing  in  many.  But  the  singular, 
from  the  fact  that  it  is  singular,  is  divided  off  from  all  others. 
Hence  every  name  imposed  to  signify  any  singular  thing  is 
incommunicable  both  in  reality  and  idea:  for  the  plurality 
of  this  individual  thing  cannot  be ;  nor  can  it  be  conceived 
in  idea.  Hence  no  name  signifying  any  individual  thing 
is  properly  communicable  to  many,  but  only  by  way  of 
similitude;  as  for  instance  a  person  can  be  called  Achilles 
metaphorically,  forasmuch  as  he  may  possess  something  of 
the  properties  of  Achilles,  such  as  strength.  On  the  other 
hand,  forms  which  are  individualized  not  by  any  supposifum, 
but  by  and  of  themselves,  as  being  subsisting  forms,  if  under- 
stood as  they  are  in  themselves,  could  not  be  communicable 
either  in  reality  or  in  idea;  but  only  perhaps  by  way  of 
similitude,  as  was  said  of  individuals.  Forasmuch  as  we 
are  unable  to  understand  simple  self-subsisting  forms  as 
they  really  are,  we  understand  them  as  compound  things 
having  forms  in  matter;  therefore,  as  was  said  in  the  first 
article,  we  give  them  concrete  names  signifying  a  nature 
existing  in  some  suppositum.     Hence,  so  far  as  concerns 


Q.  13.  Art.  9   THE  "  SUMMA  THEOLOGICA  "  172 

names,  the  same  rules  apply  to  names  we  impose  to  signify 
the  nature  of  compound  things  as  to  names  given  by  us  to 
signify  simple  subsisting  natures. 

Since,  then,  this  name  God  is  given  to  signify  the  divine 
nature  as  stated  above  (A.  8),  and  since  the  divine  nature 
cannot    be   multiplied    as   shown  above  (Q.  XL  A.  3),  it 
follows  that  this  name  God  is  incommunicable  in  reality,  but 
communicable  in  opinion ;  just  in  the  same  way  as  this  name 
sun  would  be  communicable  according  to  the  opinion  of 
those  who  say  there  are  many  suns.     Therefore,  it  is  written: 
You  served  them  who  by  nature  are  not  gods  (Gal.iv.  8),  and  a 
gloss  adds,  Gods  not  in  nature,  hut  in  human  opinion.     Never- 
theless this  name  God  is  communicable,  not  in  its  whole  sig- 
nification, but  in  some  part  of  it  by  way  of  similitude ;  so  that 
those  are  called  gods  who  share  in  divinity  by  likeness,  ac- 
cording to  the  text,  /  have  said,  You  are  gods  (Ps.  Ixxxi.  6). 
But  if  any  name  were  given  to  signify  God  not  as  to  His 
nature  but   as  to  His  suppositum,  accordingly  as  He  is 
considered  as  this  something,  that  name  would  be  absolutely 
incommunicable;  as,  for  instance,  perhaps  the  Tetragram- 
maton  among  the  Hebrews ;  and  this  is  like  giving  a  name 
to  the  sun  as  signifying  this  individual  thing. 

Reply  Ohj,  i.  The  divine  nature  is  only  communicable 
according  to  the  participation  of  some  similitude. 

Reply  Ohj.  2.  This  name  God  is  an  appellative  name,  and 
not  a  proper  name,  for  it  signifies  the  divine  nature  in  the 
possessor;  although  God  Himself  in  reality  is  neither  univer- 
sal nor  particular.  For  names  do  not  follow  upon  the  mode 
of  being  in  things,  but  upon  the  mode  of  being  as  it  is  in  our 
mind.  And  yet  it  is  incommunicable  according  to  the  truth 
of  the  thing,  as  was  said  above  concerning  the  name  sun. 

Reply  Ohj.  3.  These  names  good,  wise,  and  the  like,  are 
imposed  from  the  perfections  proceeding  from  God  to 
creatures;  but  they  do  not  signify  the  divine  nature,  but 
rather  signify  the  perfections  themselves  absolutely;  and 
therefore  they  are  in  truth  communicable  to  many.  But  this 
name  God  is  given  to  God  from  His  own  proper  operation, 
which  we  experience  continually,  to  signify  the  divine  nature. 


173  THE  NAMES  OF  GOD  Q.  13.  Art.  10 


Tenth  Article. 

whether  this  name  god  is  applied  to  god  univocally, 
by  nature,  by  participation,  and  according  to 

OPINION  ? 

We  proceed  thus  to  the  Tenth  Article  : — 

Objection  i.  It  seems  that  this  name  God  is  applied  to 
God  univocally  by  nature,  by  participation,  and  according 
to  opinion.  For  where  a  diverse  signification  exists,  there  is 
no  contradiction  of  affirmation  and  negation ;  for  equivoca- 
tion prevents  contradiction.  But  a  Catholic  who  says:  An 
idol  is  not  God,  contradicts  a  pagan  who  says :  An  idol  is  God. 
Therefore  God  in  both  senses  is  spoken  of  univocally. 

Obj.  2.  Further,  as  an  idol  is  God  in  opinion,  and  not  in 
truth,  so  the  enjoyment  of  carnal  pleasures  is  called  happi- 
ness in  opinion,  and  not  in  truth.  But  this  name  eatitude 
is  applied  univocally  to  this  supposed  happiness,  and  also  to 
true  happiness.  Therefore  also  this  name  God  is  applied 
univocally  to  the  true  God;  and  to  God  also  in  opinion. 

Obj.  3.  Further,  names  are  called  univocal  because  they 
contain  one  idea.  Now  when  a  Catholic  says:  There  is  one 
God,  he  understands  by  the  name  of  God  an  omnipotent 
being,  and  one  venerated  above  all;  while  the  heathen 
understands  the  same  when  he  says :  An  idol  is  God.  There- 
fore this  name  God  is  applied  univocally  to  both. 

On  the  contrary,  The  idea  in  the  intellect  is  the  likeness 
of  what  is  in  the  thing  as  is  said  in  Periherm.  i.  But  the 
word  animal  applied  to  a  true  animal,  and  to  a  picture  of 
one,  is  equivocal.  Therefore  this  name  God  applied  to  the 
true  God  and  to  God  in  opinion,  is  applied  equivocally. 

F'urther,  No  one  can  signify  what  he  does  not  know. 
But  the  heathen  does  not  know  the  divine  nature.  So  when 
he  says  an  idol  is  God,  he  does  not  signify  the  true  Deity. 
On  the  other  hand,  a  Catholic  signifies  the  true  Deity  when 
he  says  there  is  one  God.  Therefore  this  name  God  is  not 
applied  univocally,  but  equivocally  to  the  true  God,  and  to 
God  according  to  opinion. 


Q  13.  Art.  10    THE  "  SUMMA  THEOLOGICA  "  174 

/  answer  that,  This  name  God  in  the  three  aforesaid 
significations  is  taken  neither  univocally  nor  equivocally, 
but  analogically.  This  is  apparent  from  this  reason: — 
Univocal  terms  mean  absolutely  the  same  thing,  but 
equivocal  terms  absolutely  different ;  whereas  in  analogical 
terms  a  word  taken  in  one  signification  must  be  placed  in 
the  definition  of  the  same  word  taken  in  other  senses;  as, 
for  instance,  being  which  is  applied  to  substance  is  placed 
in  the  definition  of  being  as  applied  to  accident;  and  healthy 
applied  to  animal  is  placed  in  the  definition  of  healthy  as 
applied  to  urine  and  medicine.  For  urine  is  the  sign  of 
health  in  the  animal,  and  medicine  is  the  cause  of  health. 

The  same  applies  to  the  question  at  issue.  For  this 
name  God,  as  signifying  the  true  God,  includes  the  idea  of 
God  when  it  is  used  to  denote  God  in  opinion,  or  partici- 
pation. For  when  we  name  anyone  god  by  participation, 
we  understand  by  the  name  of  god  some  likeness  of  the  true 
God.  Likewise,  when  we  call  an  idol  god,  by  this  name 
god  we  understand  and  signify  something  which  men  think 
is  God;  thus  it  is  manifest  that  the  name  has  different 
meanings,  but  that  one  of  them  is  comprised  in  the  other 
significations.     Hence  it  is  manifestly  said  analogically. 

Reply  Obj.  1.  The  multiplication  of  names  does  not 
depend  on  the  predication  of  the  name,  but  on  the  significa- 
tion: for  this  name  man,  of  whomsoever  it  is  predicated, 
whether  truly  or  falsely,  is  predicated  in  one  sense.  But  it 
would  be  multiplied  if  by  the  name  man  we  meant  to  signify 
different  things ;  for  instance,  if  one  meant  to  signify  by  this 
name  man  what  man  really  is,  and  another  meant  to  signify 
by  the  same  name  a  stone,  or  something  else.  Hence  it  is 
evident  that  a  Catholic  saying  that  an  idol  is  not  God 
contradicts  the  pagan  asserting  that  it  is  God ;  because  each 
of  them  uses  this  name  God  to  signify  the  true  God.  For 
when  the  pagan  says  an  idol  is  God,  he  does  not  use  this 
name  as  meaning  God  in  opinion,  for  he  would  then  speak 
the  truth,  as  also  Catholics  sometimes  use  the  name  in  that 
sense,  as  in  the  Psalm,  All  the  gods  of  the  Gentiles  are  demons 
(Ps.  xcv.  5). 


175  THE  NAMES  OF  GOD         Q.  13.  Art.  h 

The  same  remark  applies  to  the  second  and  third  Objec- 
tions. For  those  reasons  proceed  from  the  different  pre- 
dication of  the  name,  and  not  from  its  various  significations. 

Reply  Ohj.  4.  The  term  animal  apphed  to  a  true  and 
a  pictured  animal  is  not  purely  equivocal;  for  the  Philoso- 
pher takes  equivocal  names  in  a  large  sense,  including 
analogous  names;  because  also  being,  which  is  predicated 
analogically,  is  sometimes  said  to  be  predicated  equivocally 
of  different  predicaments. 

Reply  Ohj.  5.  Neither  a  Catholic  nor  a  pagan  knows  the 
very  nature  of  God  as  it  is  in  itself;  but  each  one  knows 
it  according  to  some  idea  of  causality,  or  excellence,  or 
remotion  (Q.  XII.  A.  12).  So  a  pagan  can  take  this  name 
God  in  the  same  way  when  he  says  an  idol  is  God,  as  the 
Catholic  does  in  saying  an  idol  is  not  God.  But  if  anyone 
should  be  quite  ignorant  of  God  altogether,  he  could  not 
even  name  Him,  unless,  perhaps,  as  we  use  names  the 
meaning  of  which  we  know  not. 

Eleventh  Article, 
whether  this  name,  he  who  is,  is  the  most  proper  name 

OF   GOD  ? 

We  proceed  thus  to  the  Eleventh  A  rticle : — 

Objection  i.  It  seems  that  this  name  HE  WHO  IS  is  not 
the  most  proper  name  of  God.  For  this  name  God  is  an 
incommunicable  name.  But  this  name'  ^HE  WHO  IS,  is  not 
an  incommunicable  name.  Therefore  this  name  HE  WHO 
IS  is  not  the  most  proper  name  of  God. 

Obj.  2.  Further,  Dionysius  says  {Div.  Nom.  iii.)  that 
the  name  of  good  excellently  manifests  all  the  processions  of 
God.  But  it  especially  belongs  to  God  to  be  the  universal 
principle  of  all  things.  Therefore  this  name  good  is 
supremely  proper  to  God,  and  not  this  name  HE  WHO  IS. 

Obj.  3.  Further,  every  divine  name  seems  to  imply 
relation  to  creatures,  for  God  is  known  to  us  only  through 
creatures.  But  this  name^H£:  WHO  IS,  imports  no  relation 
to  creatures.  Therefore  this  name  HE  WHO  IS,  is  not  the 
most  applicable  to  God. 


g.  13.  Art.  II    THE  "  SUMMA  THEOLOGICA  "  176 

On  the  contrary,  It  is  written  that  when  Moses  asked,  // 
they  should  say  to  me,  What  is  His  name  ?  what  shall  I  say 
to  them  ?  the  Lord  answered  him,  Thus  shall  thou  say  to  them, 
HE  WHO  IS  hath  sent  me  to  you  (Exod.  iii.  13,  14).  There- 
fore this  name,  HE  WHO  IS,  most  properly  belongs  to  God. 

/  answer  that,  This  name,  HE  WHO  IS,  is  most  properly 
applied  to  God,  for  three  reasons : — 

First,  because  of  its  signification.  For  it  does  not  signify 
form,  but  simply  existence  itself.  Hence  since  the  existence 
of  God  is  His  essence  itself,  which  can  be  said  of  no  other 
(Q.  III.  A.  4),  it  is  clear  that  among  other  names  this  one 
specially  denominates  God,  for  everything  is  denominated 
by  its  form. 

Secondly,  on^ccount  of  its  universality.  For  all  other 
names  are  either  less  universal,  or,  if  convertible  with 
it,  add  something  above  it  at  least  in  idea;  hence  in  a 
certain  way  they  inform  and  determine  it.  Now  our 
intellect  cannot  know  the  essence  of  God  itself  in  this  life, 
as  it  is  in  itself,  but  whatever  mode  it  appHes  in  determin- 
ing what  it  understands  about  God,  it  falls  short  of  the 
mode  of  what  God  is  in  Himself.  Therefore  the  less  deter- 
minate the  names  are,  and  the  more  universal  and  absolute 
they  are,  the  more  properly  are  they  applied  to  God.  Hence 
Damascene  says  (De  Fid.  Orth.  i.)  that,  HE  WHO  IS,  is  the 
principal  of  all  names  applied  to  God;  for  comprehending 
all  in  itself,  it  contains  existence  itself  as  an  infinite  and 
indeterminate  sea  of  substance.  Now  by  any  other  name 
some  mode  of  substance  is  determined,  whereas  this  name 
HE  WHO  IS,  determines  no  mode  of  being,  but  is  indeter- 
minate to  all;  and  therefore  it  denominates  the  infinite 
ocean  of  substance. 

Thirdly,  from  its  consignification,  for  it  signifies  present 
existence ;  and  this  above  all  properly  applies  to  God,  whose 
existence  knows  not  past  or  future,  as  Augustine  says  (Dc 
Trin.  v.). 

Reply  Obj.  1.  This  name  HE  WHO  IS,  is  the  name  of 
God  more  properly  than  this  name  God,  as  regards  its  source, 
namely,  existence;  and  as  regards  the  mode  of  signification 


177  THE  NAMES  OF  GOD  Q.  13.  Art.  12 

and  consignification,  as  said  above.  But  as  regards  the 
object  intended  by  the  name,  this  name  God  is  more  proper, 
as  it  is  imposed  to  signify  the  divine  nature ;  and  still  more 
proper  is  the  Tetragrammaton,  imposed  to  signify  the 
substance  of  God  itself,  incommunicable  and,  if  one  may  so 
speak,  singular. 

Reply  Obj.  2.  This  name  good  is  the  principal  name  of 
God  in  so  far  as  He  is  a  cause,  but  not  absolutely;  for 
existence  considered  absolutely  comes  before  the  idea  of 
cause. 

Reply  Obj.  3.  It  is  not  necessary  that  all  the  divine 
names  should  import  relation  to  creatures,  but  it  suffices 
that  they  be  imposed  from  some  perfections  flowing  from 
God  to  creatures.  Among  these  the  first  is  existence,  from 
which  comes  this  name,  HE  WHO  IS. 


Twelfth  Article. 

whether  affirmative  propositions  can  be  formed 

about  god  ? 

We  proceed  thus  to  the  Twelfth  Article  : — 

Objection  i.  It  seems  that  affirmative  propositions  cannot 
be  formed  about  God.  For  Dionysius  says  {Ccel.  Hier.  ii.) 
that  negations  about  God  are  true;  but  affirmations  are  vague. 

Obj.  2.  Further,  Boethius  says  [De  Trin.  ii.),  that  a 
simple  form  cannot  be  a  subject.  But  God  is  the  most 
absolutely  simple  form,  as  shown  (Q.  III.):  therefore  He 
cannot  be  a  subject.  But  everything  about  which  an  affir- 
mative proposition  is  made  is  taken  as  a  subject.  Therefore 
an  affirmative  proposition  cannot  be  formed  about  God. 

Obj.  3.  Further,  every  intellect  is  false  which  understands 
a  thing  otherwise  than  as  it  is.  But  God  has  existence 
without  any  composition  as  shown  above  {Q.  iii.  A.  7). 
Therefore  since  every  affirmative  intellect  understands 
something  as  compound,  it  follows  that  a  true  affirmative 
proposition  about  God  cannot  be  made. 

On  the  contrary,  What  is  of  faith  cannot  be  false.     But 
some  affirmative  propositions  are  of  faith;  as  that  God  is 
I.  12 


Q.  13.  Art.  12  ^THE  "  SUMMA  THEOLOGICA  "  178 

Three  and  One;  and  that  He  is  omnipotent.    Therefore 
true  affirmative  propositions  can  be  formed  about  God. 

/  answer  that,  True  affirmative  propositions  can  be  formed 
about  God.  To  prove  this  we  must  know  that  in  every 
true  affirmative  proposition  the  predicate  and  the  subject 
signify  in  some  way  the  same  thing  in  reality,  and  different 
things  in  idea.  And  this  appears  to  be  the  case  both  in 
propositions  which  have  an  accidental  predicate,  and  in 
those  which  have  an  essential  predicate.  For  it  is  manifest 
that  man  and  white  are  the  same  in  subject,  and  different  in 
idea ;  for  the  idea  of  man  is  one  thing,  and  that  of  whiteness  is 
another.  The  same  applies  when  I  say,  man  is  an  animal; 
since  the  same  thing  which  is  man  is  truly  animal;  for  in  the 
same  suppositum  there  is  sensible  nature  by  reason  of  which  he 
is  called  animal,  and  the  rational  nature  by  reason  of  which 
he  is  called  man;  hence  here  again  predicate  and  subject  are 
the  same  as  to  suppositum,  but  different  as  to  idea.  But  in 
propositions  where  one  same  thing  is  predicated  of  itself, 
the  same  rule  in  some  way  applies,  inasmuch  as  the  intellect 
draws  to  the  suppositum  what  it  places  in  the  subject;  and 
what  it  places  in  the  predicate  it  draws  to  the  nature  of  the 
form  existing  in  the  suppositum;  according  to  the  saying 
ih.3.t  predicates  are  to  be  taken  formally ,  and  subjects  materially. 
To  this  diversity  in  idea  corresponds  the  plurality  of 
predicate  and  subject,  while  the  intellect  signifies  the 
identity  of  the  thing  by  the  composition  itself. 

God,  however,  as  considered  in  Himself,  is  altogether  one 
and  simple,  yet  our  intellect  knows  Him  by  different 
conceptions  because  it  cannot  see  Him  as  He  is  in  Himself. 
Nevertheless,  although  it  understands  Him  under  different 
conceptions,  it  knows  that  one  and  the  same  simple  object 
corresponds  to  its  conceptions.  Therefore  the  plurality 
of  predicate  and  subject  represents  the  plurality  of  idea; 
and  the  intellect  represents  the  unity  by  composition. 

Reply  Obj.  i.  Dionysius  says  that  the  affirmations  about 
God  are  vague  or,  according  to  another  translation, 
incongruous,  inasmuch  as  no  name  can  be  applied  to  God 
according  to  its  mode  of  signification. 


179  THE  NAMES  OF  GOD  Q.  13.  Art.  12 

Reply  Obj.  2.  Our  intellect  cannot  comprehend  simple 
subsisting  forms,  as  they  really  are  in  themselves;  but  it 
apprehends  them  as  compound  things  in  which  there  is 
something  taken  as  subject  and  something  that  is  inherent. 
Therefore  it  apprehends  the  simple  form  as  a  subject,  and 
attributes  something  else  to  it. 

Reply  Obj.  3.  This  proposition.  The  intellect  understanding 
anything  otherwise  than  it  is,  is  false,  can  be  taken  in  two 
senses,  accordingly  as  this  adverb  otherwise  determines  the 
word  understanding  on  the  part  of  the  thing  understood,  or 
on  the  part  of  the  one  who  understands.  Taken  as  referring 
to  the  thing  understood,  the  proposition  is  true,  and  the 
meaning  is :  Any  intellect  which  understands  that  the  thing 
is  otherwise  than  it  is,  is  false.  But  this  does  not  hold  in  the 
present  case;  because  our  intellect,  when  forming  a  pro- 
position about  God,  does  not  affirm  that  He  is  composite, 
but  that  He  is  simple.  But  taken  as  referring  to  the  one 
who  understands,  the  proposition  is  false.  For  the  mode 
of  the  intellect  in  understanding  is  different  from  the  mode 
of  the  thing  in  its  essence.  Since  it  is  clear  that  our  intellect 
understands  material  things  below  itself  in  an  immaterial 
manner;  not  that  it  understands  them  to  be  immaterial 
things;  but  its  manner  of  understanding  is  immaterial. 
Likewise,  when  it  understands  simple  things  above  itself,  it 
understands  them  according  to  its  own  mode,  which  is  in  a 
composite  manner;  yet  not  so  as  to  understand  them  to 
be  composite  things.  And  thus  our  intellect  is  not  false  in 
forming  composition  in  its  ideas  concerning  God. 


QUESTION  XIV. 

OF  GOD'S  KNOWLEDGE. 
{In  Sixteen  Articles.) 

Having  considered  what  belongs  to  the  divine  substance, 
we  have  now  to  treat  of  God's  operation.  And  since  one 
kind  of  operation  is  immanent,  and  another  kind  of  opera- 
tion proceeds  to  the  exterior  effect,  we  treat  first  of  know- 
ledge and  of  will  (for  understanding  abides  in  the  intelligent 
agent,  and  will  is  in  the  one  who  wills) ;  and  afterwards  of 
the  power  of  God,  the  principle  of  the  divine  operation  as 
proceeding  to  the  exterior  effect.  Now  because  to  under- 
stand is  a  kind  of  life,  after  treating  of  the  divine  knowledge, 
we  consider  the  divine  life.  And  as  knowledge  concerns 
truth,  we  consider  truth  and  falsehood.  Further,  as  every- 
thing known  is  in  the  knower,  and  the  types  of  things 
as  existing  in  the  knowledge  of  God  are  called  ideas,  to  the 
consideration  of  knowledge  will  be  added  the  treatment 
of  ideas. 

Concerning  knowledge,  there  are  sixteen  points  for  inquiry : 
(i)  Whether  there  is  knowledge  in  God  ?  (2)  Whether

First  Article, 
whether  there  is  knowledge*  in  god  ? 

We  proceed  thus  to  the  First  Article : — 

Objection  i.  It  seems  that  in  God  there  is  not  knowledge. 
For  knowledge  is  a  habit;  and  habit  does  not  belong  to 
God,  since  it  is  the  mean  between  potentiality  and  act. 
Therefore  knowledge  is  not  in  God. 

Obj.  2.  Further,  since  science  is  about  conclusions^  it  is 
a  kind  of  knowledge  caused  by  something  else  which 
is  the  knowledge  of  principles.  But  nothing  is  caused  in 
God;  therefore  science  is  not  in  God. 

Obj.  3.  Further,  all  knowledge  is  universal,  or  particular. 
But  in  God  there  is  no  universal  nor  particular  (Q.  III., 
A.  5).     Therefore  in  God  there  is  not  knowledge. 

On  the  contrary,  The  Apostle  says,  0  the  depth  of  the 
riches  of  the  wisdom  and  of  the  knowledge  of  God  (Rom.  xi.  33) . 

I  answer  that,  In  God  there  exists  the  most  perfect  know- 
ledge. To  prove  this,  we  must  note  that  intelligent  beings 
are  distinguished  from  non-intelligent  beings  in  that  the 
latter  possess  only  their  own  form;  whereas  the  intelligent 
being  is  naturally  adapted  to  have  also  the  form  of  some  other 
thing;  for  the  idea  of  the  thing  known  is  in  the  knower. 
Hence  it  is  manifest  that  the  nature  of  a  non-intelligent  being 
is  more  contracted  and  limited ;  whereas  the  nature  of  intelli- 
gent beings  has  a  greater  amplitude  and  extension ;  therefore 
the  Philosopher  says  [De  Anima  iii.)  that  the  soul  is  in  a  sense 
all  things.  Now  the  contraction  of  the  form  comes  from 
the  matter.  Hence,  as  we  have  said  above  (Q.  VII.,  A.  1) 
forms  according  as  they  are  the  more  immaterial,  approach 
more  nearly  to  a  kind  of  infinity.  Therefore  it  is  clear  that 
the  immateriality  of  a  thing  is  the  reason  why  it  is  cognitive ; 
and  according  to  the  mode  of  immateriality  is  the  mode  of 
knowledge.     Hence,  it  is  said  in  De  Anima  ii.  that  plants  do 

*  Scientia. 


Q.  14.  Art.  1    THE  '*  SUMMA  THEOLOGICA  "  182 

not  know,  because  they  are  wholly  material.  But  sense  is 
cognitive  because  it  can  receive  images  free  from  matter, 
and  the  intellect  is  still  further  cognitive,  because  it  is  more 
separated  from  matter  and  unmixed,  as  said  in  De  Anima  iii. 
Since  therefore  God  is  in  the  highest  degree  of  immateriality 
as  stated  above  (Q.  VII.,  A.  i),  it  follows  that  He  occupies 
the  highest  place  in  knowledge. 

Reply  Ohj.  i.  Because  perfections  flowing  from  God  to 
creatures  exist  in  a  higher  state  in  God  Himself  (Q.  IV.,  A.  2), 
whenever  a  name  taken  from  any  created  perfection  is 
attributed  to  God,  it  must  be  separated  in  its  signification 
from  anything  that  belongs  to  that  imperfect  mode  proper 
to  creatures.  Hence  knowledge  is  not  a  quality  in  God, 
nor  a  habit;  but  substance  and  pure  act. 

Reply  Ohj.  2.  Whatever  is  divided  and  multiplied  in 
creatures  exists  in  God  simply  and  unitedly  (Q.  XIII.,  A.  4). 
Now  man  has  different  kinds  of  knowledge,  according  to  the 
different  objects  of  his  knowledge.  He  has  intelligence  as 
regards  the  knowledge  of  principles ;  he  has  science  as  regards 
knowledge  of  conclusions;  he  has  wisdom,  according  as  he 
knows  the  highest  cause;  he  has  counsel  or  prudence y  accord- 
ing as  he  knows  what  is  to  be  done.  But  God  knows  all 
these  by  one  simple  act  of  knowledge,  as  will  be  shown 
(A.  7).  Hence  the  simple  knowledge  of  God  can  be  named 
by  all  these  names ;  in  such  a  way,  however,  that  there  must 
be  removed  from  each  of  them,  so  far  as  they  enter  into  the 
divine  predication,  everything  that  savours  of  imperfection ; 
and  everything  that  expresses  perfection  is  to  be  retained 
in  them.  Hence  it  is  said,  With  Him  is  wisdom  and  strength, 
He  hath  counsel  and  understanding  (Job  xii.  13) . 

Reply  Ohj.  3.  Knowledge  is  according  to  the  mode  of 
the  one  who  knows;  for  the  thing  known  is  in  the  knower 
according  to  the  mode  of  the  knower.  Now  since  the  mode 
of  the  divine  essence  is  higher  than  that  of  creatures,  divine 
knowledge  does  not  exist  in  God  after  the  mode  of  created 
knowledge,  so  as  to  be  universal  or  particular,  or  habitual, 
or  potential,  or  existing  according  to  any  such  mode. 


i83  GOD'S  KNOWLEDGE  Q.  14.  Art.  2 


Second  Article, 
whether  god  understands  himself  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  1.  It  seems  that  God  does  not  understand  Him- 
self. For  it  is  said  by  the  Philosopher  (De  Causis),  Every 
knower  who  knows  his  own  essence,  returns  completely  to  his 
own  essence.  But  God  does  not  go  out  from  His  own  essence, 
nor  is  He  moved  at  all;  thus  He  cannot  return  to  His  own 
essence.     Therefore  He  does  not  know  His  own  essence. 

Ohj.  2.  Further,  to  understand  is  a  kind  of  passion  and 
movement,  as  the  Philosopher  says  [De  Anima  iii.);  and 
knowledge  also  is  a  kind  of  assimilation  to  the  object  known; 
and  the  thing  known  is  the  perfection  of  the  knower.  But 
nothing  is  moved,  or  suffers,  or  is  made  perfect  by  itself,  nor, 
as  Hilary  says  (De  Trin.  iii.),  is  a  thing  its  own  likeness. 
Therefore  God  does  not  understand  Himself. 

Ohj.  3.  Further,  we  are  like  to  God  chiefly  in  our  intellect, 
because  we  are  the  image  of  God  in  our  mind,  as  Augustine 
says  {Gen.  ad.  lit.  vi.).  But  our  intellect  understands  itself, 
only  as  it  understands  other  things,  as  is  said  in  De  Anima  iii. 
Therefore  God  understands  Himself  only  so  far  perchance 
as  He  understands  other  things. 

On  the  contrary,  It  is  written:  The  things  that  a^'e  of  God  no 
man  knoweth,  hut  the  Spirit  of  God  (i  Cor.  ii.  11). 

/  answer  that,  God  understands  Himself  through  Himself. 
In  proof  whereof  it  must  be  known  that  although  in  opera- 
tions which  pass  to  an  external  effect,  the  object  of  the 
operation,  which  is  taken  as  the  term,  exists  outside  the 
operator;  nevertheless  in  operations  that  remain  in  the 
operator,  the  object  signified  as  the  term  of  operation, 
resides  in  the  operator;  and  accordingly  as  it  is  in  the 
operator,  the  operation  is  actual.  Hence  the  Philosopher 
says  {De  Aniina  iii.),  that  the  sensible  in  act  is  sense  in  act, 
and  the  intelligible  in  act  is  intellect  in  act.  For  the  reason 
why  we  actually  feel  or  know  a  thing  is  because  our  intellect 
or  sense  is  actually  informed  by  the  sensible  or  intelligible 


Q.  14.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  184 

species.  And  because  of  this  only,  it  follows  that  sense  or 
intellect  is  distinct  from  the  sensible  or  intelligible  object, 
since  both  are  in  potentiality. 

Since  therefore  God  has  nothing  in  Him  of  potentiality, 
but  is  pure  act,  His  intellect  and  its  object  are  altogether 
the  same;  so  that  He  neither  is  without  the  intelligible 
species,  as  is  the  case  with  our  intellect  when  it  understands 
potentiall}^;  nor  does  the  intelligible  species  differ  from  the 
substance  of  the  divine  intellect,  as  it  differs  in  our  intellect 
when  it  understands  actually;  but  the  intelligible  species 
itself  is  the  divine  intellect  itself,  and  thus  God  understands 
Himself  through  Himself. 

Reply  Obj.  i.  Return  to  its  own  essence  means  only  that 
a  thing  subsists  in  itself.  Inasmuch  as  the  form  perfects 
the  matter  by  giving  it  existence,  it  is  in  a  certain  way 
diffused  in  it;  and  it  returns  to  itself  inasmuch  as  it  has 
existence  in  itself.  Therefore  those  cognitive  faculties 
which  are  not  subsisting,  but  are  the  acts  of  organs,  do  not 
know  themselves,  as  in  the  case  of  each  of  the  senses; 
whereas  those  cognitive  faculties  which  are  subsisting, 
know  themselves ;  hence  it  is  said  in  De  Causis  that,  whoever 
knows  his  essence  returns  to  it.  Now  it  supremely  belongs 
to  God  to  be  self-subsisting.  Hence  according  to  this  mode 
of  speaking,  He  supremely  returns  to  His  own  essence,  and 
knows  Himself. 

Reply  Obj.  2.  Movement  and  passion  are  taken  equivo- 
cally, according  as  to  understand  is  described  as  a  kind  of 
movement  or  passion,  as  stated  in  De  Anima  iii.  For  to 
understand  is  not  a  movement  that  is  an  act  of  something 
imperfect  passing  from  one  to  another,  but  it  is  an  act, 
existing  in  the  agent  itself,  of  something  perfect.  Likewise 
that  the  intellect  is  perfected  by  the  intelligible  object, 
^'.^.,  is  assimilated  to  it,  this  belongs  to  an  intellect  which  is 
sometimes  in  potentiality ;  because  the  fact  of  its  being  in  a 
state  of  potentiality  makes  it  differ  from  the  intelHgible  object 
and  assimilates  it  thereto  through  the  intelligible  species, 
which  is  the  likeness  of  the  thing  understood,  and  makes 
it  to  be  perfected  thereby,  as  potentiality  is  perfected  by 


i85  GOD'S  KNOWLEDGE  Q.  14.  Art.  3 

act.  On  the  other  hand  the  divine  intellect,  which  is  no 
way  in  potentiaHty,  is  not  perfected  by  the  intelligible  object, 
nor  is  it  assimilated  thereto,  but  is  its  own  perfection,  and 
its  own  intelligible  object. 

Reply  Obj.  3.  Existence  in  nature  does  not  belong  to 
primary  matter,  which  is  a  potentiality,  unless  it  is  reduced 
to  act  by  a  form.  Now  our  passive  intellect  has  the  same 
relation  to  intelligible  objects  as  primary  matter  has  to 
natural  things;  for  it  is  in  potentiaHty  as  regards  intelligible 
objects,  just  as  primary  matter  is  to  natural  things.  Hence 
our  passive  intellect  can  be  exercised  concerning  intelligible 
objects  only  so  far  as  it  is  perfected  by  the  intelligible  species 
of  something;  and  in  that  way  it  understands  itself  by  an 
intelligible  species,  as  it  understands  other  things :  for  it  is 
manifest  that  by  knowing  the  intelHgible  object  it  under- 
stands also  its  own  act  of  understanding,  and  by  this  act 
knows  the  intellectual  faculty.  But  God  is  a  pure  act  in 
the  order  of  existence,  as  also  in  the  order  of  intelligible 
objects;  therefore  He  understands  Himself  through  Himself. 

Third  Article, 
whether  god  comprehends  himself  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  God  does  not  comprehend 
Himself.  For  Augustine  says  {Octog.  Tri.  QucBst.  xv.),  that 
whatever  comprehends  itself  is  finite  as  regards  itself.  But  God 
is  in  all  ways  infinite.  Therefore  He  does  not  comprehend 
Himself. 

Obj.  2.  If  it  be  said  that  God  is  infinite  to  us,  and  finite  to 
Himself,  it  can  be  urged  to  the  contrary,  that  everything 
in  God  is  truer  than  it  is  in  us.  If  therefore  God  is  finite  to 
Himself,  but  infinite  to  us,  then  God  is  more  truly  finite 
than  infinite;  which  is  against  what  was  laid  down  above 
(Q.  VII. ,  A.  I) .  Therefore  God  does  not  comprehend  Himself. 

On  the  contrary,  Augustine  says  [ibid.),  Everything  that 
understands  itself,  comprehends  itself.  But  God  understands 
Himself.    Therefore  He  comprehends  Himself. 


Q.  14.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  186 

/  answer  that,  God  perfectly  comprehends  Himself, 
as  can  be  thus  proved.  A  thing  is  said  to  be  compre- 
hended when  the  end  of  the  knowledge  of  it  is  attained, 
and  this  is  accomplished  when  it  is  known  as  perfectly 
as  it  is  knowable;  as,  for  instance,  a  demonstrable  proposi- 
tion is  comprehended  when  known  by  demonstration,  not, 
however,  when  it  is  known  by  some  probable  reason. 
Now  it  is  manifest  that  God  knows  Himself  as  perfectly 
as  He  is  perfectly  knowable.  For  everything  is  knowable 
according  to  the  mode  of  its  own  actuality;  since  a  thing  is 
not  known  according  as  it  is  in  potentiality,  but  in  so  far 
as  it  is  in  actuality,  as  said  in  Metaph.  ix.  Now  the  power 
of  God  in  knowing  is  as  great  as  His  actuality  in  existing; 
because  it  is  from  the  fact  that  He  is  in  act  and  free  from  all 
matter  and  potentiality,  that  God  is  cognitive,  as  shown 
above  (AA.  i  and  2).  Whence  it  is  manifest  that  He  knows 
Himself  as  much  as  He  is  knowable;  and  for  that  reason 
He  perfectly  comprehends  Himself. 

Reply  Obj.  i.  The  strict  meaning  of  cow/)r^A^wstow  signifies 
that  one  thing  holds  and  includes  another;  and  in  this 
sense  everything  comprehended  is  finite,  as  also  is  every- 
thing included  in  another.  But  God  is  not  said  to  be 
comprehended  by  Himself  in  this  sense,  as  if  His  intellect 
were  a  faculty  apart  from  Himself,  and  as  if  it  held  and 
included  Himself;  for  these  modes  of  speaking  are  to  be 
taken  by  way  of  negation.  But  as  God  is  said  to  be  in 
Himself,  forasmuch  as  He  is  not  contained  by  anything 
outside  of  Himself;  so  He  is  said  to  be  comprehended  by 
Himself,  forasmuch  as  nothing  in  Himself  is  hidden  from 
Himself.  For  Augustine  says  [De  VicL  Dcum.  ep,  cxii.).  The 
whole  is  comprehended  when  seen,  if  it  is  seen  in  such  a  way 
that  nothing  of  it  is  hidden  from  the  seer. 

Reply  Obj,  2.  When  it  is  said,  God  is  finite  to  Himself, 
this  is  to  be  understood  according  to  a  certain  similitude  of 
proportion,  because  He  has  the  same  relation  in  not  exceed- 
ing His  intellect,  as  anything  finite  has  in  not  exceeding  finite 
intellect.  But  God  is  not  to  be  called  finite  to  Himself  in 
this  sense,  as  if  He  understood  Himself  to  be  something  finite. 


i87  GOD'S  KNOWLEDGE  Q.  14.  Art.  4 


Fourth  Article. 

WHETHER   THE  ACT  OF  GOD's   INTELLECT   IS    HIS 
SUBSTANCE  ? 

We  proceed  thus  to  the  Fourth  Article : — 

Objection  i.  It  seems  that  the  act  of  God's  intellect  is 
not  His  substance.  For  to  understand  is  an  operation. 
But  an  operation  signifies  something  proceeding  from  the 
operator.  Therefore  the  act  of  God's  intellect  is  not  His 
substance. 

Oh],  2.  Further,  To  understand  one's  act  of  understand- 
ing, is  to  understand  something  that  is  neither  great  nor 
chiefly  understood,  but  secondary  and  accessory.  If  there- 
fore God  be  his  own  act  of  understanding,  His  act  of  under- 
standing will  be  as  when  we  understand  our  act  of  under- 
standing: and  thus  God's  act  of  understanding  will  not 
be  something  great. 

Ohj.  3.  Further,  every  act  of  understanding  means  under- 
standing something.  When  therefore  God  understands 
Himself,  if  He  Himself  is  not  distinct  from  this  act  of  under- 
standing, He  understands  that  He  understands,  and  that 
He  understands  that  He  understands  Himself;  and  so  on  to 
infinity.  Therefore  the  act  of  God's  intellect  is  not  His 
substance. 

On  the  contrary,  Augustine  says  (De  Trin.  vii.). 
In  God  to  be  is  the  same  as  to  be  wise.  But  to  be  wise 
is  the  same  thing  as  to  understand.  Therefore  in  God 
to  be  is  the  same  thing  as  to  understand.  But  God's 
existence  is  His  substance,  as  shown  above  (Q.  III.,  A.  4). 
Therefore  the  act  of  God's  intellect  is  His  substance. 

I  answer  that,  It  must  be  said  that  the  act  of  God's  intellect 
is  His  substance.  For  if  His  act  of  understanding  were 
other  than  His  substance,  then  something  else,  as  the 
Philosopher  says  [Metaph.  xii.),  would  be  the  act  and 
perfection  of  the  divine  substance,  to  which  the  divine 
substance  would  be  related,  as  potentiality  is  to  act,  which 
is  altogether  impossible;  because  the  act  of  understanding 


Q.  14.  Art.  5    THE  "  SUMMA  THEOLOGICA  ''  188 

is  the  perfection  and  act  of  the  one  understanding.  Let  us 
now  consider  how  this  is.  As  was  laid  down  above  (A.  2),  to 
understand  is  not  an  act  passing  to  anything  extrinsic;  for 
it  remains  in  the  operator  as  his  own  act  and  perfection ;  as 
existence  is  the  perfection  of  the  one  existing:  just  as 
existence  follows  on  the  form,  so  in  like  manner  to  under- 
stand follows  on  the  intelligible  species.  Now  in  God  there 
is  no  form  which  is  something  other  than  His  existence,  as 
shown  above  (Q.  III.).  Hence  as  His  essence  itself  is  also 
His  intelligible  species,  it  necessarily  follows  that  His  act  of 
understanding  must  be  His  essence  and  His  existence. 

Thus  it  follows  from  all  the  foregoing  that  in  God,  intellect, 
and  the  object  understood,  and  the  intelligible  species,  and 
His  act  of  understanding  are  entirely  one  and  the  same. 
Hence,  when  God  is  said  to  be  understanding,  no  kind  of 
multiplicity  is  attached  to  His  substance. 

Reply  Obj.  i.  To  understand  is  not  an  operation  pro- 
ceeding out  of  the  operator,  but  remaining  in  him. 

Reply  Obj.  2.  When  that  act  of  understanding  which  is 
not  subsistent  is  understood,  something  not  great  is  under- 
stood ;  as  when  we  understand  our  act  of  understanding ;  and 
so  this  cannot  be  likened  to  the  act  of  the  divine  under- 
standing which  is  subsistent. 

Thus  appears  the  Reply  to  Obj.  3.  For  the  act  of  divine 
understanding  subsists  in  itself,  and  belongs  to  its  very  self 
and  is  not  another's;  hence  it  need  not  proceed  to  infinity. 

Fifth  Article. 

whether  god  knows  things  other  than  himself  ? 

We  proceed  thus  to  the  Fifth  Article  : — 

Objection  1.  It  seems  that  God  does  not  know  things 
besides  Himself.  For  all  other  things  but  God  are  outside 
of  God.  But  Augustine  says  [Octog.  Tri.  QucBst.,  qu.  xlvi.) 
that  God  does  not  behold  anything  out  of  Himself.  There- 
fore He  does  not  know  things  other  than  Himself. 

Obj.  2.  Further,  the  object  understood  is  the  perfection 
of  the  one  who  understands.     If  therefore  God  understands 


i89  GOD'S  KNOWLEDGE  Q.  14.  Art.  5 

other  things  besides  Himself,  something  else  will  be  the 
perfection  of  God,  and  will  be  nobler  than  He;  which  is 
impossible. 

Ohj.  3.  Further,  the  act  of  understanding  is  specified 
by  the  intelligible  object,  as  is  every  other  act  from  its 
own  object.  Hence  the  intellectual  act  is  so  much  the 
nobler,  the  nobler  the  object  understood.  But  God  is  His 
own  intellectual  act.  If  therefore  God  understands  anything 
other  than  Himself,  then  God  Himself  is  specified  by 
something  else  than  Himself;  which  cannot  be.  Therefore 
He  does  not  understand  things  other  than  Himself. 

On  the  contrary,  It  is  written:  All  things  are  naked  and 
open  to  His  eyes  (Heb.  iv.  13). 

/  answer  that,  God  necessarily  knows  things  other  than 
Himself.  For  it  is  manifest  that  He  perfectly  understands 
Himself;  otherwise  His  existence  would  not  be  perfect,  since 
His  existence  is  His  act  of  understanding.  Now  if  anything 
is  perfectly  known,  it  follows  of  necessity  that  its  power  is 
perfectly  known.  But  the  power  of  anything  can  be  per- 
fectly known  only  by  knowing  to  what  its  power  extends. 
Since  therefore  the  divine  power  extends  to  other  things  by 
the  very  fact  that  it  is  the  first  effective  cause  of  all  things, 
as  is  clear  from  the  aforesaid  (Q.  II.,  A.  3),  God  must  neces- 
sarily know  things  other  than  Himself.  And  this  appears 
still  more  plainly  if  we  add  that  the  very  existence  of  the 
first  efficient  cause — viz.,  God — is  His  own  act  of  under- 
standing. Hence  whatever  effects  pre-exist  in  God,  as  in 
the  first  cause,  must  be  in  His  act  of  understanding,  and 
all  things  must  be  in  Him  according  to  an  intelligible  mode : 
for  everything  which  is  in  another,  is  in  it  according  to  the 
mode  of  that  in  which  it  is. 

Now  in  order  to  know  how  God  knows  things  other  than 
Himself,  we  must  consider  that  a  thing  is  known  in  two  ways : 
in  itself,  and  in  another.  A  thing  is  known  in  itself  when  it 
is  known  by  the  proper  species  adequate  to  the  knowable 
object;  as  when  the  eye  sees  a  man  through  the  image  of 
a  man.  A  thing  is  seen  in  another  through  the  image  of 
that  which  contains  it;  as  when  a  part  is  seen  in  the  whole 


g.  14.  Art.  5    THE  "  SUMMA  THEOLOGICA  "  190 

by  the  image  of  the  whole ;  or  when  a  man  is  seen  in  a  mirror 
by  the  image  in  the  mirror,  or  by  any  other  mode  by  which 
one  thing  is  seen  in  another. 

So  we  say  that  God  sees  Himself  in  Himself,  because 
He  sees  Himself  through  His  essence;  and  He  sees  other 
things  not  in  themselves,  but  in  Himself;  inasmuch  as 
His  essence  contains  the  similitude  of  things  other  than 
Himself. 

Reply  Obj.  i.  The  passage  of  Augustine  in  which  it  is  said 
that  God  sees  nothing  outside  Himself  is  not  to  be  taken  in 
such  a  way,  as  if  God  saw  nothing  outside  Himself,  but  in 
the  sense  that  what  is  outside  Himself  He  does  not  see 
except  in  Himself,  as  above  explained. 

Reply  Obj.  2.  The  object  understood  is  a  perfection  of 
the  one  understanding  not  by  its  substance,  but  by  its 
image,  according  to  which  it  is  in  the  intellect,  as  its  form 
and  perfection,  as  is  said  in  De  Anima  iii.  For  a  stone  is 
not  in  the  soul,  but  its  image.  Now  those  things  which  are 
other  than  God  are  understood  by  God,  inasmuch  as  the 
essence  of  God  contains  their  images  as  above  explained; 
hence  it  does  not  follow  that  there  is  any  perfection  in  the 
divine  intellect  other  than  the  divine  essence. 

Reply  Obj.  3.  The  intellectual  act  is  not  specified  by 
what  is  understood  in  another,  but  by  the  principal  object 
understood  in  which  other  things  are  understood.  For  the 
intellectual  act  is  specified  by  its  object,  inasmuch  as  the 
intelligible  form  is  the  principle  of  the  intellectual  operation : 
since  every  operation  is  specified  by  the  form  which  is 
its  principle  of  operation;  as  heating  by  heat.  Hence  the 
intellectual  operation  is  specified  by  that  intelligible  form 
which  makes  the  intellect  in  act.  And  this  is  the  image 
of  the  principal  thing  understood,  which  in  God  is  nothing 
but  His  own  essence  in  which  all  images  of  things  are 
comprehended.  Hence  it  does  not  follow  that  the  divine 
intellectual  act,  or  rather  God  Himself,  is  specified  by 
anything  else  than  the  divine  essence  itself. 


igi  GOD'S  KNOWLEDGE  Q.  14.  Art.  6 


Sixth  Article. 

whether  god  knows  things  other  than  himself 
by  proper  knowledge  ? 

We  proceed  thus  to  the  Sixth  Article : — 

Objection  i.  It  seems  that  God  does  not  know  things  other 
than  Himself  by  proper  knowledge.  For,  as  was  shown 
(A.  5.),  God  knows  things  other  than  Himself,  according  as 
they  are  in  Himself.  But  other  things  are  in  Him  as  in 
their  common  and  universal  cause,  and  are  known  by  God  as 
in  their  first  and  universal  cause.  This  is  to  know  them 
by  general,  and  not  by  proper  knowledge.  Therefore  God 
knows  things  besides  Himself  by  general,  and  not  by  proper 
knowledge. 

Obj.  2.  Further,  the  created  essence  is  as  distant  from 
the  divine  essence,  as  the  divine  essence  is  distant  from  the 
created  essence.  But  the  divine  essence  cannot  be  known 
by  the  created  essence,  as  said  above  (Q .  XH . ,  A .  2 .) .  There  - 
fore  neither  can  the  created  essence  be  known  by  the  divine 
essence.  Thus  as  God  knows  only  by  His  essence,  it  follows 
that  He  does  not  know  what  the  creature  is  in  its  essence, 
so  as  to  know  what  it  is,  which  is  to  have  proper  knowledge 
of  it. 

Obj.  3.  Further,  proper  knowledge  of  a  thing  can  come 
only  through  its  proper  ratio.  But  as  God  knows  all 
things  by  His  essence,  it  seems  that  He  does  not  know 
each  thing  by  its  proper  ratio;  for  one  thing  cannot 
be  the  proper  ratio  of  many  and  diverse  things.  There- 
fore God  has  not  a  proper  knowledge  of  things,  but  a  general 
knowledge;  for  to  know  things  otherwise  than  by  their 
proper  ratio  is  to  have  only  a  common  and  general  know- 
ledge of  them. 

On  the  contrary,  To  have  a  proper  knowledge  of  things 
is  to  know  them  not  only  in  general,  but  as  they  are  dis- 
tinct from  each  other.  Now  God  knows  things  in  that 
manner.  Hence  it  is  written  that  He  reaches  even  to  the 
division  of  the  soul  and  the  spirit,  of  the  joints  also  and  the 


Q.  14,  Art.  6    THE   "  SUMMA  THEOLOGICA  "  192 

marrow,  and  is  a  discerned  of  the  thoughts  and  intents  of  the 
heart ;  neither  is  there  any  creature  invisible  in  His  sight 
(Heb.  iv.  12,  13). 

I  answer  that,  Some  have  erred  on  this  point,  saying  that 
God  knows  things  other  than  Himself  only  in  general,  that  is, 
only  as  beings.  For  as  fire,  if  it  knew  itself  as  the  principle 
of  heat,  would  know  the  nature  of  heat,  and  all  things  else 
in  so  far  as  they  are  hot ;  so  God,  through  knowing  Himself 
as  the  principle  of  being,  knows  the  nature  of  being,  and  all 
other  things  in  so  far  as  they  are  beings. 

But  this  cannot  be.  For  to  know  a  thing  in  general  and 
not  in  particular,  is  to  have  an  imperfect  knowledge  of  it. 
Hence  our  intellect,  when  it  is  reduced  from  potentiality 
to  act,  acquires  first  a  universal  and  confused  knowledge 
of  things,  before  it  knows  them  in  particular ;  as  proceeding 
from  the  imperfect  to  the  perfect,  as  is  clear  from  Physic,  i. 
If  therefore  the  knowledge  of  God  regarding  things  other 
than  Himself  is  only  universal  and  not  special,  it  would 
follow  that  His  understanding  would  not  be  absolutely 
perfect;  therefore  neither  would  His  being  be  perfect;  and 
this  is  against  what  was  said  above  (Q.  IV.,  A.  i).  We  must 
therefore  hold  that  God  knows  things  other  than  Himself 
with  a  proper  knowledge;  not  only  in  so  far  as  being  is 
common  to  them,  but  in  so  far  as  one  is  distinguished  from 
the  other.  In  proof  thereof  we  may  observe  that  some 
wishing  to  show  that  God  knows  many  things  by  one, 
bring  forward  some  examples,  as,  for  instance,  that  if  the 
centre  knew  itself,  it  would  know  all  lines  that  proceed  from 
the  centre;  or  if  light  knew  itself,  it  would  know  all  colours. 

Now  these  examples  although  they  are  similar  in  part, 
namely,  as  regards  universal  causality,  nevertheless  they  fail 
in  this  respect,  that  multitude  and  diversity  are  caused  by 
the  one  universal  principle,  not  as  regards  that  which  is  the 
principle  of  distinction,  but  only  as  regards  that  in  which 
they  communicate.  For  the  diversity  of  colours  is  not 
caused  by  the  light  only,  but  by  the  different  disposition 
of  the  diaphanous  medium  which  receives  it ;  and  likewise, 
the  diversity  of  the  lines  is  caused  by  their  different  position. 


193  GOD'S  KNOWLEDGE  Q.  14.  Art.  6 

Hence  it  is  that  this  kind  of  diversity  and  multitude  cannot 
be  known  in  its  principle  by  proper  knowledge,  but  only 
in  a  general  way.  In  God,  however,  it  is  otherwise.  For  it 
was  shown  above  (Q.  IV.,  A.  2)  that  whatever  perfection  exists 
in  any  creature,  wholly  pre-exists  and  is  contained  in  God  in 
an  excelling  manner.  Now  not  only  what  is  common  to 
creatures — viz.  being — belongs  to  their  perfection,  but  also 
what  makes  them  distinguished  from  each  other;  as  living 
and  understanding,  and  the  like,  whereby  living  beings  are 
distinguished  from  the  non-living,  and  the  intelligent  from 
the  non-intelligent.  Likewise  every  form  whereby  each 
thing  is  constituted  in  its  own  species,  is  a  perfection ;  and  thus 
all  things  pre-exist  in  God,  not  only  as  regards  what  is 
common  to  all,  but  also  as  regards  what  distinguishes  one 
thing  from  another.  And  therefore  as  God  contains  all 
perfections  in  Himself,  the  essence  of  God  is  compared  to  all 
other  essences  of  things,  not  as  the  common  to  the  proper, 
as  unity  is  to  numbers,  or  as  the  centre  (of  a  circle)  to  the 
(radiating)  lines;  but  as  perfect  acts  to  Imperfect;  as  if  I 
were  to  compare  man  to  animal;  or  six,  a  perfect  number, 
to  the  imperfect  numbers  contained  under  it.  Now  it  is 
manifest  that  by  a  perfect  act  imperfect  acts  can  be  known 
not  only  In  general,  but  also  by  proper  knowledge ;  thus,  for 
example,  whoever  knows  a  man,  knows  an  animal  by  proper 
knowledge ;  and  whoever  knows  the  number  six,  knows  the 
number  three  also  by  proper  knowledge. 

As  therefore  the  essence  of  God  contains  In  itself  all  the 
perfection  contained  In  the  essence  of  any  other  being,  and 
far  more,  God  can  know  In  Himself  all  of  them  with  proper 
knowledge.  For  the  nature  proper  to  each  thing  consists 
in  some  degree  of  participation  In  the  divine  perfection. 
Now  God  could  not  be  said  to  know  Himself  perfectly  unless 
He  knew  all  the  ways  in  which  His  own  perfection  can  be 
shared  by  others.  Neither  could  He  know  the  very 
nature  of  being  perfectly,  unless  He  knew  all  modes  of 
being.  Hence  it  is  manifest,  that  God  knows  all  things 
with  proper  knowledge,  in  their  distinction  from  each 
other.

Q.  14.  Art.  6   THE  "  SUMMA  THEOLOGICA  "  194 

Reply  Obj.  i.  So  to  know  a  thing  as  it  is  in  the  knower, 
may  be  understood  in  two  ways.  In  one  way  this  adverb 
so,  imports  the  mode  of  knowledge  on  the  part  of  the  thing 
known;  and  in  that  sense  it  is  false.  For  the  knower  does 
not  always  know  the  object  known  according  to  the  existence 
it  has  in  the  knower;  since  the  eye  does  not  know  a  stone 
according  to  the  existence  it  has  in  the  eye ;  but  by  the 
image  of  the  stone  which  is  in  the  eye,  the  eye  knows  the 
stone  according  to  its  existence  outside  the  eye.  And  if  any 
knower  has  a  knowledge  of  the  object  known  according  to 
the  (mode  of)  existence  it  has  in  the  knower,  the  knower 
nevertheless  khows  it  according  to  its  (mode  of)  existence  out- 
side the  knower ;  thus  the  intellect  knows  a  stone  according 
to  the  intelligible  existence  it  has  in  the  intellect,  inasmuch 
as  it  knows  that  it  understands ;  while  nevertheless  it  knows 
what  a  stone  is  in  its  own  nature.  If  however  the  adverb 
so  be  understood  to  import  the  mode  (of  knowledge)  on  the 
part  of  the  knower,  in  that  sense  it  is  true  that  only  the 
knower  has  knowledge  of  the  object  known  as  it  is  in  the 
knower;  for  the  more  perfectly  the  thing  known  is  in  the 
knower,  the  more  perfect  is  the  mode  of  knowledge. 

We  must  say  therefore  that  God  not  only  knows  that 
things  are  in  Himself ;  but  by  the  fact  that  they  are  in  Him, 
He  knows  them  in  their  own  nature  and  all  the  more  perfectly, 
the  more  perfectly  each  one  is  in  Him. 

Reply  Obj.  2.  The  created  essence  is  compared  to  the 
essence  of  God,  as  the  imperfect  to  the  perfect  act.  There- 
fore the  created  essence  cannot  sufficiently  lead  us  to 
the  knowledge  of  the  divine  essence,  but  rather  the 
converse. 

Reply  Obj.  3.  The  same  thing  cannot  be  taken  in  an 
eq  al  manner  as  the  ratio  of  different  things.  But  the 
divine  essence  excels  all  creatures.  Hence  it  can  be 
taken  as  the  proper  ratio  of  each  thing  according  to  the 
diverse  ways  in  which  diverse  creatures  participate  in,  and 
imitate  it. 


195  GOD'S  KNOWLEDGE  Q.  14.  Art.  7 


Seventh  Article, 
whether  the  knowledge  of  god  is  discursive  ? 

We  proceed  thus  to  the  Seventh  Article  : — 

Objection  i.  It  seems  that  the  knowledge  of  God  is  dis- 
cursive. For  the  knowledge  of  God  is  not  habitual  know- 
ledge, but  actual  knowledge.  Now  the  Philosopher  says 
(Topic,  ii.) :  The  habit  of  knowledge  may  regard  many  things  at 
once;  but  actual  understanding  regards  only  one  thing  at  a  time. 
Therefore  as  God  knows  many  things,  Himself  and  others, 
as  shown  above  (AA.  2,  5),  it  seems  that  He  does  not 
understand  all  at  once,  but  discourses  from  one  to  another. 

Obj.  2.  Further,  discursive  knowledge  is  to  know  the 
effect  through  its  cause.  But  God  knows  things  through 
Himself;  as  an  effect  (is  known)  through  its  cause.  There- 
fore His  knowledge  is  discursive. 

Obj.  3.  Further,  God  knows  each  creature  more  perfectly 
than  we  know  it.  But  we  know  the  effects  in  their  created 
causes;  and  thus  we  go  discursively  from  causes  to  things 
caused.     Therefore  it  seems  that  the  same  applies  to  God. 

On  the  contrary,  Augustine  says  (De  Trin.  xv.),  God  does 
not  see  all  things  in  their  particularity  or  separately,  as  if  He 
saw  alternately  here  and  there;  but  He  sees  all  things  together 
at  once. 

I  answer  that,  In  the  divine  knowledge  there  is  no  dis- 
cursion;  the  proof  of  which  is  as  follows.  In  our  know- 
ledge there  is  a  twofold  discursion;  one  is  according  to 
succession  only,  as  when  we  have  actually  understood 
anything,  we  turn  ourselves  to  understand  something  else; 
while  the  other  mode  of  discursion  is  according  to  causality, 
as  when  through  principles  we  arrive  at  the  knowledge  of 
conclusions.  The  first  kind  of  discursion  cannot  belong  to 
God.  For  many  things,  which  we  understand  in  succession 
if  each  is  considered  in  itself,  we  understand  simultaneously 
if  we  see  them  in  some  one  thing;  if,  for  instance,  we  under- 
stand the  parts  in  the  whole,  or  see  different  things  in  a 
mirror.    Now  God  sees  all  things  in  one  (thing),  which  is  Him- 


Q.  14.  Art.  8   THE  "  SUMMA  THEOLOGICA  '*  196 

self.  Therefore  God  sees  all  things  together,  and  not  succes- 
sively. Likewise  the  second  mode  of  discursion  cannot 
be  applied  to  God.  First,  because  this  second  mode  of 
discursion  presupposes  the  first  mode;  for  whosoever  pro- 
ceeds from  principles  to  conclusions  does  not  consider  both 
at  once;  secondly,  because  to  discourse  thus  is  to  proceed 
from  the  known  to  the  unknown.  Hence  it  is  manifest 
that  when  the  first  is  known,  the  second  is  still  unknown; 
and  thus  the  second  is  known  not  in  the  first,  but 
from  the  first.  Now  the  term  of  discursive  reasoning  is 
attained  when  the  second  is  seen  in  the  first,  by  resolving 
the  effects  into  their  causes;  and  then  the  discursion 
ceases.  Hence  as  God  sees  His  effects  in  Himself  as  in  their 
cause.  His  knowledge  is  not  discursive. 

Reply  Obj.  i.  Although  there  is  only  one  act  of  under- 
standing in  itself,  nevertheless  many  things  may  be  under- 
stood in  one  (medium),  as  shown  above. 

Reply  Obj.  2.  God  does  not  know  by  their  cause,  known, 
as  it  were  previously,  effects  unknown;  but  He  knows  the 
effects  in  the  cause;  and  hence  His  knowledge  is  not  dis- 
cursive, as  was  shown  above. 

Reply  Obj.  3.  God  sees  the  effects  of  created  causes  in 
the  causes  themselves,  much  better  than  we  can;  but  still 
not  in  such  a  manner  that  the  knowledge  of  the  effects  is 
caused  in  Him  by  the  knowledge  of  the  created  causes,  as 
is  the  case  with  us;  and  hence  His  knowledge  is  not  dis- 
cursive. 

Eighth  Article, 
whether  the  knowledge  of  god  is  the  cause  of 

THINGS  ? 

We  proceed  thus  to  the  Eighth  Article: — 

Objection  i.  It  seems  that  the  knowledge  of  God  is  not 
the  cause  of  things.  For  Origen  says,  on  Rom.  viii.  30,. 
Whom  He  called,  them  He  also  justified,  etc.:  A  thing 
will  happen  not  because  God  knows  it  as  future;  but  because 
it  is  future,  it  is  on  that  account  known  by  God,  before" 
it  exists. 


197  GOD'S  KNOWLEDGE  Q.  14.  Art.  8 

Ohj.  2.  Further,  given  the  cause,  the  effect  follows.  But 
the  knowledge  of  God  is  eternal.  Therefore  if  the  knowledge 
of  God  is  the  cause  of  things  created,  it  seems  that  creatures 
are  eternal. 

Ohj.  3.  Further,  The  thing  known  is  prior  to  knowledge^ 
and  is  its  measure,  as  the  Philosopher  says  (Metaph.  x.). 
But  what  is  posterior  and  measured  cannot  be  a  cause. 
Therefore  the  knowledge  of  God  is  not  the  cause  of  things. 

On  the  contrary,  Augustine  says  {De  Trin.  xv.),  Not  because 
they  are,  does  God  know  all  creatures  spiritual  and  temporal, 
but  because  He  knows  them,  therefore  they  are. 

I  answer  that.  The  knowledge  of  God  is  the  cause  of 
things.  For  the  knowledge  of  God  is  to  all  creatures  what 
the  knowledge  of  the  artificer  is  to  things  made  by  his  art. 
Now  the  knowledge  of  the  artificer  is  the  cause  of  the  things 
made  by  his  art  from  the  fact  that  the  artificer  works  by  his 
intellect.  Hence  the  form  of  the  intellect  must  be  the 
principle  of  action;  as  heat  is  the  principle  of  heating. 
Nevertheless,  we  must  observe  that  a  natural  form,  being 
a  form  that  remains  in  that  to  which  it  gives  existence, 
denotes  a  principle  of  action  according  only  as  it  has  an 
inclination  to  an  effect;  and  likewise,  the  intelligible  form 
does  not  denote  a  principle  of  action  in  so  far  as  it  resides 
in  the  one  who  understands  unless  there  is  added  to  it  the 
inclination  to  an  effect,  which  inclination  is  through  the 
will.  For  since  the  intelligible  form  has  a  relation  to 
opposite  things  (inasmuch  as  the  same  knowledge  relates 
to  opposites),  it  would  not  produce  a  determinate  efiect 
unless  it  were  determined  to  one  thing  by  the  appetite,  as 
the  Philosopher  says  {Metaph.  ix.).  Now  it  is  manifest  that 
God  causes  things  by  His  intellect,  since  His  being  is  His 
act  of  understanding;  and  hence  His  knowledge  must  be  the 
cause  of  things,  in  so  far  as  His  will  is  joined  to  it.  Hence 
the  knowledge  of  God  as  the  cause  of  things  is  usually  called 
the  knowledge  of  approbation. 

Reply  Ohj.  i.  Origen  spoke  in  reference  to  that  aspect  of 
knowledge  to  which  the  idea  of  causality  does  not  belong 
unless  the  will  is  joined  to  it,  as  is  said  abov  e. 


Q,  14.  Art.  9    THE  "  SUMMA  THEOLOGICA  "  198 

But  when  he  says  the  reason  why  God  foreknows  some 
things  is  because  they  are  future,  this  must  be  understood 
according  to  the  cause  of  consequence,  and  not  according 
to  the  cause  of  essence.  For  if  things  are  in  the  future,  it 
follows  that  God  knows  them;  but  not  that  the  futurity  of 
things  is  the  cause  why  God  knows  them. 

Reply  Obj.  2.  The  knowledge  of  God  is  the  cause  of  things 
according  as  things  are  in  His  knowledge.  Now  that  things 
should  be  eternal  was  not  in  the  knowledge  of  God;  hence 
although  the  knowledge  of  God  is  eternal,  it  does  not 
follow  that  creatures  are  eternal. 

Reply  Obj.  3.  Natural  things  are  midway  between  the 
knowledge  of  God  and  our  knowledge :  for  we  receive  know- 
ledge from  natural  things,  of  which  God  is  the  cause  by  His 
knowledge.  Hence,  as  the  natural  objects  of  knowledge 
are  prior  to  our  knowledge,  and  are  its  measure,  so,  the 
knowledge  of  God  is  prior  to  natural  things,  and  is  the 
measure  of  them;  as,  for  instance,  a  house  is  midway 
between  the  knowledge  of  the  builder  who  made  it,  and  the 
knowledge  of  the  one  who  gathers  his  knowledge  of  the 
house  from  the  house  already  built. 

Ninth  Article, 
whether  god  has  knowledge  of  things  that  are  not  ? 

We  proceed  thus  to  the  Ninth  Article  : — 

Objection  i.  It  seems  that  God  has  not  knowledge  of 
things  that  are  not.  For  the  knowledge  of  God  is  of  true 
things.  But  truth  and  being  are  convertible  terms.  There- 
fore the  knowledge  of  God  is  not  of  things  that  are  not. 

Obj.  2.  Further,  knowledge  requires  Hkeness  between  the 
knower  and  the  thing  known.  But  those  things  that  are 
not  cannot  have  any  likeness  to  God,  Who  is  very  being. 
Therefore  whut  is  not,  cannot  be  known  by  God. 

Obj.  3.  Further,  the  knowledge  of  God  is  the  cause  of 
what  is  known  by  Him .^' But  it  is  not  the  cause  of  things 
that  are  not,  because  a  thing  that  is  not,  has  no  cause.  There- 
fore God  has  no  knowledge  of  things  that  are  not. 


199  GOD'S  KNOWLEDGE  Q.  14.  Art.  9 

On  the  contrary,  The  Apostle  says :  Who  .  .  .  calleth  those 
things  that  are  not  as  those  that  are  (Rom.  iv.  17). 

/  answer  that,  God  knows  all  things  whatsoever  that  in  any 
way  are.  Now  it  is  possible  that  things  that  are  not  abso- 
lutely, should  be  in  a  certain  sense.  For  things  absolutely 
are  which  are  actual;  whereas  things  which  are  not  actual,  are 
in  the  power  either  of  God  Himself  or  of  a  creature,  whether 
in  active  power,  or  passive;  whether  in  power  of  thought 
or  of  imagination,  or  of  any  other  manner  of  meaning 
whatsoever.  Whatever  therefore  can  be  made,  or  thought, 
or  said  by  the  creature,  as  also  whatever  He  Himself  can  do, 
all  are  known  to  God,  although  they  are  not  actual.  And  in 
so  far  it  can  be  said  that  He  has  knowledge  even  of  things 
that  are  not. 

Now  a  certain  difference  is  to  be  noted  in  the  consideration 
of  those  things  that  are  not  actual.  For  though  some  of 
them  may  not  be  in  act  now,  still  they  were,  or  they  will  be ; 
and  God  is  said  to  know  all  these  with  the  knowledge  of 
vision:  for  since  God's  act  of  understanding,  which  is  His 
being,  is  measured  by  eternity;  and  since  eternity  is  without 
succession,  comprehending  all  time,  the  present  glance  of 
God  extends  over  all  time,  and  to  all  things  which  exist 
in  any  time,  as  to  objects  present  to  Him.  But  there 
are  other  things  in  God's  power,  or  the  creature's,  which 
nevertheless  are  not,  nor  will  be,  nor  were;  and  as  regards 
these  He  is  said  to  have  the  knowledge,  not  of  vision,  but  of 
simple  intelligence.  This  is  so  called  because  the  things 
we  see  around  us  have  distinct  being  outside  the  seer. 

Reply  Ohj.  i.  Those  things  that  are  not  actual  are  true  in 
so  far  as  they  are  in  potentiality;  for  it  is  true  that  they  are 
in  potentiaUty;  and  as  such  they  are  known  by  God. 

Reply  Ohj.  2.  Since  God  is  very  being  everything  is,  in  so 
far  as  it  participates  in  the  likeness  of  God;  as  everything 
is  hot  in  so  far  as  it  participates  in  heat.  So,  things  in 
potentiality  are  known  by  God,  although  they  are  not  in 
act. 

Reply  Ohj.  3  The  knowledge  of  God,  joined  to  His  will 
is  the  cause  of  things.     Hence  it  is  not  necessary  that  what 


Q.  14.  Art.  10   THE  "  SUMMA  THEOLOGICA  "  200 

ever  God  knows,  is,  or  was,  or  will  be;  but  only  is  this 
necessary  as  regards  what  He  wills  to  be,  or  permits  to  be. 
Further,  it  is  in  the  knowledge  of  God  not  that  they  be, 
but  that  they  be  possible. 

Tenth  Article, 
whether  god  knows  evil  things  ? 

We  proceed  thus  to  the  Tenth  Article  : — 

Objection  i.  It  seems  that  God  does  not  know  evil  things. 
For  the  Philosopher  (De  Anima  iii.)  says  that  the  intellect 
which  is  not  in  potentiality  does  not  know  privation.  But 
evil  is  the  privation  of  good,  as  Augustine  says  (Confess,  iii.  7). 
Therefore,  as  the  intellect  of  God  is  never  in  potentiality, 
but  is  always  in  act,  as  is  clear  from  the  foregoing  (A.  2), 
it  seems  that  God  does  not  know  evil  things. 

Obj.  2.  Further,  all  knowledge  is  either  the  cause  of  the 
thing  known,  or  is  caused  by  it.  But  the  knowledge  of  God 
is  not  the  cause  of  evil,  nor  is  it  caused  by  evil.  Therefore 
God  does  not  know  evil  things. 

Obj.  3.  Further,  everything  known  is  known  either  by  its 
likeness,  or  by  its  opposite.  But  whatever  God  knows,  He 
knows  through  His  essence,  as  is  clear  from  the  foregoing 
(A.  5).  Now  the  divine  essence  neither  is  the  likeness  of 
evil,  nor  is  evil  contrary  to  it;  for  to  the  divine  essence 
there  is  no  contrary,  as  Augustine  says  (De  Civ.  Dei  xii.). 
Therefore  God  does  not  know  evil  things. 

Obj.  4.  Further,  what  is  known  through  another  and  not 
through  itself,  is  imperfectly  known.  But  evil  is  not  known 
by  God  through  itself,  otherwise  evil  would  be  in  God;  for 
the  thing  known  must  be  in  the  knower.  Therefore  if  evil 
is  known  through  another,  namely,  through  good,  it  would 
be  known  by  Him  imperfectly;  which  cannot  be,  for  the 
knowledge  of  God  is  not  imperfect.  Therefore  God  does 
not  know  evil  things. 

On  the  contrary,  It  is  written  (Prov.  xv.  11),  Hell  and 
destruction  are  before  God  (Vulg.,  the  Lord). 

I  answer  that,  Whoever  knows  a  thing   perfectly,  must 
know  all  that  can  be  accidental  to  it.    Now  there  are  some 


201  GOD'S  KNOWLEDGE  Q.  14.  Art.  ii 

good  things  to  which  corruption  by  evil  may  be  accidental. 
Hence  God  would  not  know  good  things  perfectly,  unless  He 
also  knew  evil  things.  Now  a  thing  is  knowable  in  the  degree 
in  which  it  is ;  hence,  since  this  is  the  essence  of  evil  that  it 
is  the  privation  of  good,  by  the  very  fact  that  God  knows 
good  things.  He  knows  evil  things  also ;  as  by  light  is  known 
darkness.  Hence  Dionysius  says  (Div.  Nom.  vii.) :  God 
through  Himself  receives  the  vision  of  darkness,  not  otherwise 
seeing  darkness  except  through  light. 

Reply  Obj.  i.  The  saying  of  the  Philosopher  must  be  under- 
stood as  meaning  that  the  intellect  which  is  not  in  poten- 
tiaUty,  does  not  know  privation  by  privation  existing  in 
it;  and  this  agrees  with  what  he  had  said  previously,  that 
a  point  and  every  indivisible  thing  are  known  by  privation 
of  division.  This  is  because  simple  and  indivisible  forms 
are  in  our  intellect  not  actually,  but  only  potentially: 
for  were  they  actually  in  our  intellect,  they  would  not 
be  known  by  privation.  It  is  thus  that  simple  things 
are  known  by  separate  substances.  God  therefore  knows 
evil,  not  by  privation  existing  in  Himself,  but  by  the 
opposite  good. 

Reply  Obj.  2.  The  knowledge  of  God  is  not  the  cause  of 
evil;  but  is  the  cause  of  the  good  whereby  evil  is  known. 

Reply  Obj.  3.  Although  evil  is  not  opposed  to  the  divine 
essence,  which  is  not  corruptible  by  evil;  it  is  opposed 
to  the  effects  of  God,  which  He  knows  by  His  essence;  and 
knowing  them.  He  knows  the  opposite  evils. 

Reply  Obj.  4.  To  know  a  thing  by  something  else  only, 
belongs  to  imperfect  knowledge,  if  that  thing  is  of  itself 
knowable;  but  evil  is  not  of  itself  knowable,  forasmuch  as 
the  very  nature  of  evil  means  the  privation  of  good;  there- 
fore evil  can  neither  be  defined  nor  known  except  by  good. 

Eleventh  Article, 
whether  god  knows  singular  things  ? 

We  proceed  thus  to  the  Eleventh  Article: — 
Objection  i.  It  seems  that  God  does  not  know  singular 
things.     For  the  divine  intellect  is  more  immaterial  than 


Q.  14.  Art.  ii     THE  "  SUMMA  THEOLOGICA  "  202 

the  human  intellect.  Now  the  human  intellect  by  reason  of 
its  immateriality  does  not  know  singular  things;  but  as  the 
Philosopher  says  {De  Anima  ii.),  reason  has  to  do  with 
universals,  sense  with  singular  things.  Therefore  God  does 
not  know  singular  things. 

Ohj.  2.  Further,  in  us  those  faculties  alone  know  the 
singular,  which  receive  the  species  not  abstracted  from 
material  conditions.  But  in  God  things  are  in  the  highest 
degree  abstracted  from  all  materiality.  Therefore  God  does 
not  know  singular  things. 

Ohj.  3.  Further,  all  knowledge  comes  about  through  the 
medium  of  some  likeness.  But  the  likeness  of  singular 
things  in  so  far  as  they  are  singular,  does  not  seem  to  be  in 
God;  for  the  principle  of  singularity  is  matter,  which,  since 
it  is  in  potentiaUty  only,  is  altogether  unlike  God,  Who  is 
pure  act.     Therefore  God  cannot  know  singular  things. 

On  the  contrary,  It  is  written  (Prov.  xvi.  2),  All  the  ways 
of  a  man  are  open  to  His  eyes. 

I  answer  that,  God  knov/s  singular  things.  For  all  perfec- 
tions found  in  creatures  pre-exist  in  God  in  a  higher  way,  as  is 
clear  from  the  foregoing  (Q .  IV.,  A .  2) .  Now  to  know  singular 
things  is  part  of  our  perfection.  Hence  God  must  know 
singular  things.  Even  the  Philosopher  considers  it  incon- 
gruous that  anything  known  by  us  should  be  unknown  to 
God;  and  thus  against  Empedocles  he  argues  (De  Anima  i. 
and  Metaph.  iii.)  that  God  would  be  most  ignorant  if  He 
did  not  know  discord.  Now  the  perfections  which  are 
divided  among  inferior  beings,  exist  simply  and  unitedly  in 
God;  hence,  although  by  one  faculty  we  know  the  universal 
and  immaterial,  and  by  another  we  know  singular  and 
material  things,  nevertheless  God  knows  both  by  His  simple 
intellect. 

Now  some,  wishing  to  show  how  this  can  be,  said  that  God 
knows  singular  things  by  universal  causes.  For  nothing 
exists  in  any  singular  thing,  that  does  not  arise  from  some 
universal  cause.  They  give  the  example  of  an  astrologer 
who  knows  all  the  universal  movements  of  the  heavens,  and 
can  thence  foretell  all  eclipses  that  are  to   come.     This, 


203  GOD'S  KNOWLEDGE  Q.  14.  Art.  ii 

however,  is  not  enough;  for  singular  things  from  universal 
causes  attain  to  certain  forms  and  powers  which,  however 
they  may  be  joined  together,  are  not  individualized  except 
by  individual  matter.  Hence  he  who  knows  Socrates 
because  he  is  white,  or  because  he  is  the  son  of  Sophroniscus, 
or  because  of  something  of  that  kind,  would  not  know  him 
in  so  far  as  he  is  this  particular  man.  Hence  according  to 
the  aforesaid  mode,  God  would  not  know  singular  things  in 
their  singularity. 

On  the  other  hand,  others  have  said  that  God  knows 
singular  things  by  the  application  of  universal  causes  to 
particular  effects.  But  this  will  not  hold ;  forasmuch  as  no 
one  can  apply  a  thing  to  another  unless  he  first  knows  that 
thing;  hence  the  said  application  cannot  be  the  reason  of 
knowing  the  particular,  for  it  presupposes  the  knowledge  of 
singular  things. 

Therefore  it  must  be  said  otherwise,  that,  since  God  is  the 
cause  of  things  by  His  knowledge,  as  stated  above  (A.  8), 
His  knowledge  extends  as  far  as  His  causality  extends. 
Hence  as  the  active  power  of  God  extends  not  only  to 
forms,  which  are  the  source  of  universality,  but  also  to 
matter,  as  we  shall  prove  further  on  (Q.  XLIV.,  A.  2), 
he  knowledg  of  God  must  extend  to  singular  things, 
which  are  individualized  by  matter.  For  since  He  knows 
things  other  than  Himself  by  His  essence,  as  being  the 
likeness  of  things,  or  as  their  active  principle,  His  essence 
must  be  the  sufficing  principle  of  knowing  all  things  made  bv 
Him,  not  only  in  the  universal,  but  also  in  the  singular. 
The  same  would  apply  to  the  knov/ledge  of  the  artificer,  if 
it  were  productive  of  the  whole  thing,  and  not  only  of  the 
form. 

Reply  Obj.  i.  Our  intellect  abstracts  the  intelligible  species 
from  the  individualizing  principles;  hence  the  intelligible 
species  in  our  intellect  cannot  be  the  likeness  of  the  individual 
principles ;  and  on  that  account  our  intellect  does  not  know 
the  singular.  But  the  intelligible  species  in  the  divine 
intellect,  which  is  the  essence  of  God,  is  immaterial  not  by 
abstraction,  but  of   itself,   being  the  principle  of  all  the 


Q.  14.  Art.  12  THE  ''  SUMMA  THEOLOGICA  "  204 

principles  which  enter  into  the  composition  of  things, 
whether  principles  of  the  species  or  principles  of  the  indi- 
vidual; hence  by  it  God  knows  not  only  universal,  but  also 
singular  things. 

Reply  Obj.  2.  Although  as  regards  the  species  in  the 
divine  intellect  its  being  has  no  material  conditions  like  the 
images  received  in  the  imagination  and  sense,  yet  its  power 
extends  to  both  immaterial  and  material  things. 

Reply  Obj.  3.  Although  matter  as  regards  its  potentiality 
recedes  from  likeness  to  God,  yet,  even  in  so  far  as  it  has 
being  in  this  wise,  it  retains  a  certain  likeness  to  the  divine 
being. 

Twelfth  Article, 
whether  god  can  know  infinite  things  ? 

We  proceed  thus  to  the  Twelfth  Article  : — 

Objection  i.  It  seems  that  God  cannot  know  infinite 
things.  For  the  infinite,  as  such,  is  unknown;  since  the 
infinite  is  that  which,  to  those  who  measure  it,  leaves  always 
something  more  to  be  measured,  as  the  Philosopher  says 
{Physic,  iii.).  Moreover,  Augustine  says  {De  Civ.  Dei  xii.) 
that  whatever  is  comprehended  by  knowledge,  is  bounded  by 
the  comprehension  of  the  knower.  Now  infinite  things  have 
no  boundary.  Therefore  they  cannot  be  comprehended  by 
the  knowledge  of  God. 

Obj.  2.  Further,  if  we  say  that  things  infinite  in  them- 
selves are  finite  in  God's  knowledge,  against  this  it  may  be 
urged  that  the  essence  of  the  infinite  is  that  it  is  untra- 
versable,  and  the  finite  that  it  is  traversable,  as  said  in 
Physic,  iii.  But  the  infinite  is  not  traversable  either  by 
the  finite  or  by  the  infinite,  as  is  proved  in  Physic,  vi. 
Therefore  the  infinite  cannot  be  bounded  by  the  finite,  nor 
even  by  the  infinite;  and  so  the  infinite  cannot  be  finite 
in  God's  knowledge,  which  is  infinite. 

Obj.  3.  Further,  the  knowledge  of  God  is  the  measure  of 
what  is  known.  But  it  is  contrary  to  the  essence  of  the 
infinite  that  it  be  measured.  Therefore  infinite  things 
cannot  be  known  by  God. 


205  GOD'S  KNOWLEDGE  Q.  14.  Art.  12 

On  the  contrary,  Augustine  says  (De  Civ.  Dei  xii.).  Although 
we  cannot  number  the  infinite,  nevertheless  it  can  he  compre- 
hended by  Him  whose  knowledge  has  no  bounds. 

I  answer  that,  Since  God  knows  not  only  things  actual 
but  also  things  possible  to  Himself  or  to  created  things,  as 
shown  above  (A.  9),  and  as  these  must  be  infinite,  it  must 
be  held  that  He  knows  infinite  things.  Although  the  know- 
ledge of  vision  which  has  relation  only  to  things  that  are, 
or  will  be,  or  were,  is  not  of  infinite  things,  as  some  say,  for 
we  do  not  say  that  the  world  is  eternal,  nor  that  generation 
and  movement  will  go  on  for  ever,  so  that  individuals  be 
infinitely  multiplied;  yet,  if  we  consider  more  attentively, 
we  must  hold  that  God  knows  infinite  things  even  by  the 
knowledge  of  vision.  For  God  knows  even  the  thoughts 
and  affections  of  hearts,  which  will  be  multiphed  to  infinity 
as  rational  creatures  go  on  for  ever. 

The  reason  of  this  is  to  be  found  in  the  fact  that  the 
knowledge  of  every  knower  is  measured  by  the  mode 
of  the  form  which  is  the  principle  of  knowledge.  For  the 
sensible  image  in  sense  is  the  Hkeness  of  only  one  individual 
thing,  and  can  give  the  knowledge  of  only  one  individual. 
But  the  intelHgible  species  of  our  intellect  is  the  likeness  of 
the  thing  as  regards  its  specific  nature,  which  is  participable 
by  infinite  particulars;  hence  our  intellect  by  the  intelligible 
species  of  man  in  a  certain  way  knows  infinite  men;  not 
however  as  distinguished  from  each  other,  but  as  com- 
municating in  the  nature  of  the  species;  and  the  reason  is 
because  the  intelUgible  species  of  our  intellect  is  the  like- 
ness of  man  not  as  to  the  individual  principles,  but  as  to  the 
prmciples  of  the  species.  On  the  other  hand,  the  divine 
essence,  whereby  the  divine  intellect  understands,  is  a  suffic- 
ing hkeness  of  all  things  that  are,  or  can  be,  not  only  as 
regards  the  universal  principles,  but  also  as  regards  the 
principles  proper  to  each  one,  as  shown  above.  Hence  it 
follows  that  the  knowledge  of  God  extends  to  infinite  things, 
even  as  distinct  from  each  other. 

Reply  Obj.  i.  The  idea  of  the  infinite  pertains  to  quantity, 
as    the    Philosopher   says   (Physic,   i.).     But   the   idea   of 


Q.  14.  Art.  13    THE  "  SUMMA  THEOLOGICA  "  206 

quantity  implies  the  order  of  parts.  Therefore  to  know  the 
infinite  according  to  the  mode  of  the  infinite  is  to  know  part 
after  part;  and  in  this  way  the  infinite  cannot  be  known;  for 
whatever  quantity  of  parts  be  taken,  there  will  always 
remain  something  else  outside.  But  God  does  not  know 
the  infinite  or  infinite  things,  as  if  He  enumerated  part  after 
part;  since  He  knows  all  things  simultaneously,  and  not 
successively,  as  said  above  (A.  7).  Hence  there  is  nothing 
to  prevent  Him  from  knowing  infinite  things. 

Reply  Obj.  2.  Transition  imports  a  certain  succession  of 
parts;  and  hence  it  is  that  the  infinite  cannot  be  traversed 
by  the  finite,  nor  by  the  infinite.  But  equality  sufiices 
for  comprehension,  because  that  is  said  to  be  comprehended 
which  has  nothing  outside  the  comprehender.  Hence,  it  is 
not  against  the  idea  of  the  infinite  to  be  comprehended  by 
the  infinite.  And  so,  what  is  infinite  in  itself  can  be  called 
finite  to  the  knowledge  of  God  as  comprehended;  but  not 
as  if  it  were  traversable. 

Reply  Obj.  3.  The  knowledge  of  God  is  the  measure  of 
things,  not  quantitatively,  for  the  infinite  is  not  subject  to 
this  kind  of  measure;  but  it  is  the  measure  of  the  essence 
and  truth  of  things.  For  everything  has  truth  of  nature 
according  to  the  degree  in  which  it  imitates  the  knowledge  of 
God,  as  the  thing  made  by  art  agrees  with  the  art.  Granted, 
however,  an  actually  infinite  number  of  things,  for  instance, 
an  infinitude  of  men,  or  an  infinitude  in  continuous  quantity, 
as  an  infinitude  of  air,  as  some  of  the  ancients  held;  yet  it 
is  manifest  that  these  would  have  a  determinate  and  finite 
being,  because  their  being  would  be  limited  to  some  deter- 
minate nature.  Hence  they  would  be  measurable  as  regards 
the  knowledge  of  God. 

Thirteenth  Article. 

whether  the  knowledge  of  god  is  of  future 
contingent  things  ? 

We  proceed  thus  to  the  Thirteenth  Article  : — 
Objection  i.  It  seems  that  the  knowledge  of  God  is  not  of 
luture  contingent  things.    For  from  a  necessary  cause  pro- 


207  GOD'S  KNOWLEDGE  Q.  14.  Art.  13 

ceeds  a  necessary  effect.  But  the  knowledge  of  God  is  the 
cause  of  things  known,  as  said  above  (A.  8).  Since  therefore 
that  knowledge  is  necessary,  what  He  knows  must  also  be 
necessary.  Therefore  the  knowledge  of  God  is  not  of  con- 
tingent things. 

Obj.  2.  Further,  every  conditional  proposition  of  which 
the  antecedent  is  absolutely  necessary,  must  have  an 
absolutely  necessary  consequent.  For  the  antecedent  is 
to  the  consequent  as  principles  are  to  the  conclusion:  and 
from  necessary  principles  only  a  necessary  conclusion  can 
follow,  as  is  proved  in  Poster,  i.  But  this  is  a  true  con- 
ditional proposition,  If  God  knew  that  this  thing  will  be,  it 
will  be,  for  the  knowledge  of  God  is  only  of  true  tilings.  Now 
the  antecedent  conditional  of  this  is  absolutely  necessary, 
because  it  is  eternal,  and  because  it  is  signified  as  past. 
Therefore  the  consequent  is  also  absolutely  necessary. 
Therefore  whatever  God  knows,  is  necessary;  and  so  the 
knowledge  of  God  is  not  of  contingent  things. 

Obj.  3.  Further,  everything  known  by  God  must  neces- 
sarily be,  because  even  what  we  ourselves  know,  must 
necessarily  be ;  and,  of  course,  the  knowledge  of  God  is  much 
more  certain  than  ours.  But  no  future  contingent  thing 
must  necessarily  be.  Therefore  no  contingent  future  thing 
is  known  by  God. 

On  the  contrary,  It  is  written  (Ps.  xxxii.  15),  He  Who  hath 
made  the  hearts  of  every  one  of  them;  Who  understandeth  all 
their  works ,  that  is,  of  men.  Now  the  works  of  men  are 
contingent,  being  subject  to  free  will.  Therefore  God 
knows  future  contingent  things.. 

/  answer  that,  Since  as  was  shown  above  (A.  9),  God  knows 
all  things;  not  only  things  actual  but  also  things  possible 
to  Him  and  the  creature;  and  since  some  of  these  are 
future  contingent  to  us,  it  follows  that  God  knows  future 
contingent  things. 

In  evidence  of  this,  we  must  consider  that  a  contingent 
thing  can  be  considered  in  two  ways;  first,  in  itself,  in  so  far 
as  it  is  now  in  act :  and  in  this  sense  it  is  not  considered  as 
future,  but  as  present ;  neither  is  it  considered  as  contingent 
(as  having  reference  ~  to  one  of  two  terms,  but  as  determined 


Q.  14.  Art.  13  THE  "  SUMMA  THEOLOGICA  "  208 

to  one;  and  on  account  of  this  it  can  be  infallibly  the  object 
of  certain  knowledge,  for  instance  to  the  sense  of  sight,  as  when 
I  see  that  Socrates  is  sitting  down.  In  another  way  a 
contingent  thing  can  be  considered  as  it  is  in  its  cause ;  and 
in  this  way  it  is  considered  as  future,  and  as  a  contingent 
thing  not  yet  determined  to  one;  forasmuch  as  a  contingent 
cause  has  relation  to  opposite  things:  and  in  this  sense  a 
contingent  thing  is  not  subject  to  any  certain  knowledge. 
Hence,  whoever  knows  a  contingent  effect  in  its  cause  only, 
has  merely  a  conjectural  knowledge  of  it.  Now  God  knows 
all  contingent  things  not  only  as  they  are  in  their  causes,  but 
also  as  each  one  of  them  is  actually  in  itself.  And  although 
contingent  things  become  actual  successively,  nevertheless 
God  knows  contingent  things  not  successively,  as  they  are 
in  their  own  being,  as  we  do ;  but  simultaneously.  The  reason 
is  because  His  knowledge  is  measured  by  eternity,  as  is 
also  His  being;  and  eternity  being  simultaneously  whole 
comprises  all  time,  as  said  above  (Q.  X.,  A.  2).  Hence,  all 
things  that  are  in  time  are  present  to  God  from  eternity, 
not  only  because  He  has  the  types  of  things  present  within 
Him,  as  some  say;  but  because  His  glance  is  carried  from 
eternity  over  all  things  as  they  are  in  their  presentiality. 
Hence  it  is  manifest  that  contingent  things  are  infallibly 
known  by  God,  inasmuch  as  they  are  subject  to  the  divine 
sight  in  their  presentiality;  yet  they  are  future  contingent 
things  in  relation  to  their  own  causes. 

Reply  Obj.  i.  Although  the  supreme  cause  is  necessary, 
the  effect  may  be  contingent  by  reason  of  the  proximate 
contingent  cause;  just  as  the  germination  of  a  plant  is 
contingent  by  reason  of  the  proximate  contingent  cause, 
although  the  movement  of  the  sun  which  is  the  first  cause, 
is  necessary .  So  likewise  things  known  by  God  are  contingent 
on  account  of  their  proximate  causes,  while  the  knowledge 
of  God,  which  is  the  first  cause,  is  necessary. 

Reply  Obj.  2.  Some  say  that  this  antecedent,  God  knew 
this  contingent  to  be  future,  is  not  necessarj',  but  contingent; 
because,  although  it  is  past,  still  it  imports  relation  to  the 
future.     This  however  does  not  remove  necessity  from  it; 


:209  GOD'S  KNOWLEDGE  Q.  14.  Art.  13 

for  whatever  has  had  relation  to  the  future,  must  have  had  it, 
although  the  future  sometimes  does  not  follow.  On  the 
other  hand  some  say  that  this  antecedent  is  contingent, 
because  it  is  a  compound  of  necessary  and  contingent ;  as  this 
saying  is  contingent,  Socrates  is  a  white  man.  But  this  also 
is  to  no  purpose ;  for  when  we  say,  God  knew  this  contingent 
to  he  future,  contingent  is  used  here  only  as  the  matter  of  the 
word,  and  not  as  the  chief  part  of  the  proposition.  Hence 
its  contingency  or  necessity  has  no  reference  to  the  necessity 
or  contingency  of  the  proposition,  or  to  its  being  true  or  false. 
For  it  may  be  just  as  true  that  I  said  a  man  is  an  ass,  as  that 
I  said  Socrates  runs,  or  God  is:  and  the  same  applies  to 
necessary  and  contingent.  Hence  it  must  be  said  that 
this  antecedent  is  absolutely  necessary.  Nor  does  it  follow, 
as  some  say,  that  the  consequent  is  absolutely  necessary, 
because  the  antecedent  is  the  remote  cause  of  the  consequent, 
which  is  contingent  by  reason  of  the  proximate  cause.  But 
this  is  to  no  purpose.  For  the  conditional  would  be  false 
were  its  antecedent  the  remote  necessary  cause,  and  the 
consequent  a  contingent  effect;  as,  for  example,  if  I  said, 
if  the  sun  moves,  the  grass  will  grow. 

Therefore  we  must  reply  otherwise;  that  when  the  ante- 
cedent contains  anything  belonging  to  an  act  of  the  soul, 
the  consequent  must  be  taken  not  as  it  is  in  itself,  but  as  it  is 
in  the  soul :  for  the  existence  of  a  thing  in  itself  is  different 
from  the  existence  of  a  thing  in  the  soul.  For  example,  when 
I  say,  What  the  soul  understands  is  immaterial;  this  is  to  be 
understood  that  it  is  immaterial  as  it  is  in  the  intellect,  not 
as  it  is  in  itself.  Likewise  if  I  say,  //  God  knew  anything,  it 
will  he,  the  consequent  must  be  understood  as  it  is  subject  to 
the  divine  knowledge,  that  is,  as  it  is  in  its  presentiality. 
And  thus  it  is  necessary,  as  also  is  the  antecedent :  for  every" 
thing  that  is,  while  it  is,  must  necessarily  he,  as  the  Philosopher 
says  in  Periherm.  i.

(they  are  certain)  to  God  alone,  whose  understanding  is  in 
eternity  above  time.  Just  as  he  who  goes  along  the  road, 
does  not  see  thos«  who  eome  after  him ;  whereas  he  who  sees 
the  whole  road  from  a  height,  sees  at  once  all  travelling  by 
the  way.  Hence  what  is  known  by  us  must  be  necessary 
even  as  it  is  in  itself;  for  what  is  future  contingent  in  itself, 
cannot  be  known  by  us.  Whereas  what  is  known  by  God 
must  be  necessary  according  to  the  mode  in  which  they  are 
subject  to  the  divine  knowledge,  as  already  stated,  but  not 
absolutely  as  considered  in  their  own  causes.  Hence  also 
this  proposition,  Everything  known  by  God  must  necessarily 
he,  is  usually  distinguished;  for  this  may  refer  to  the  thing, 
or  to  the  saying.  If  it  refers  to  the  thing,  it  is  divided, 
and  false;  for  the  sense  is.  Everything  which  God  knows  is 
necessary.  If  understood  of  the  saying  it  is  composite  and 
true ;  for  the  sense  is.  This  proposition, '  that  which  is  known 
by  God  is  '  is  necessary. 

Now  some  urge  an  objection  and  say  that  this  distinc- 
tion holds  good  with  regard  to  forms  that  are  separable 
from  the  subject;  thus  if  I  said,  It  is  possible  for  a  white 
thing  to  be  black,  it  is  false  as  applied  to  the  saying,  and  true 
as  applied  to  the  thing :  for  a  thing  which  is  white,  can 
become  black;  whereas  this  saying,  a  white  thing  is  black, 
can  never  be  true.  But  in  forms  that  are  inseparable  from 
the  subject,  this  distinction  does  not  hold,  for  instance,  if 
I  said,  A  black  crow  can  be  white,  for  in  both  senses  it  is 
false.  Now  to  be  known  by  God  is  inseparable  from  the 
thing;  for  what  is  known  by  God  cannot  be  not  known. 
This  objection,  however,  would  hold  if  these  words  that 
which  is  known  implied  any  disposition  inherent  to  the 
subject ;  but  since  they  import  an  act  of  the  knower,  some- 
thing can  be  attributed  to  the  thing  known,  in  itself  (even 
if  it  always  be  known),  which  is  not  attributed  to  it  in  so  far 
as  it  stands  under  actual  knowledge;  thus  material  exist- 
ence is  attributed  to  a  stone  in  itself,  which  is  not  attributed 
to  it  inasmuch  as  it  is  known. 


211  GOD'S  KNOWLEDGE  Q.  14.  Art.  14 

Fourteenth  Article, 
whether  god  knows  enunciable  things  ? 

We  proceed  thus  to  the  Fourteenth  Article  : — 

Objection  i.  It  seems  that  God  does  not  know  enunciable 
things.  For  to  know  enunciable  things  belongs  to  our 
intellect  as  it  composes  and  divides.  But  in  the  divine 
intellect  there  is  no  composition.  Therefore  God  does  not 
know  enunciable  things. 

Obj.  2.  Further,  every  kind  of  knowledge  is  made  through 
some  likeness.  But  in  God  there  is  no  likeness  of  enun- 
ciable things,  since  He  is  altogether  simple.  Therefore  God 
does  not  know  enunciable  things. 

On  the  contrary,  It  is  written:  The  Lord  knoweth  the  thoughts 
oj  men  (Ps.  xciii.  11).  But  enunciable  things  are  contained 
in  the  thoughts  of  men.  Therefore  God  knows  enunciable 
things. 

I  answer  that,  Since  it  is  in  the  power  of  our  intellect  to 
form  enunciations,  and  since  God  knows  whatever  is  in  His 
own  power  or  in  that  of  creatures,  as  said  above  (A.  9), 
it  follows  of  necessity  that  God  knows  all  enunciations  that 
can  be  formed. 

Now  just  as  He  knows  material  things  immaterially,  and 
composite  things  simply,  so  likewise  He  knows  enunciable 
things  not  after  the  manner  of  enunciable  things,  as  if  in 
His  intellect  there  were  composition  or  division  of  enuncia- 
tions; for  He  knows  each  thing  by  simple  intelligence,  by 
understanding  the  essence  of  each  thing ;  as  if  we  by  the  very 
fact  that  we  understand  what  man  is,  were  to  understand 
all  that  can  be  predicated  of  man.  This,  however,  does  not 
happen  in  our  intellect,  which  discourses  from  one  thing  to 
another,  forasmuch  as  the  intelligible  species  represents  one 
thing  in  such  a  way  as  not  to  represent  another.  Hence 
when  we  understand  what  man  is,  we  do  not  forthwith 
understand  other  things  which  belong  to  him,  but  we 
understand  them  one  by  one,  according  to  a  certain  succes- 
sion.   On  this  account  the  things  w<^  understand  as  separated , 


Q.  14.  Art.  15    THE  "  SUMMA  THEOLOGICA  "  212 

we  must  reduce  to  one  by  way  of  composition  or  division, 
by  forming  an  enunciation.  Now  the  species  of  the  divine 
intellect,  which  is  God's  essence,  suffices  to  represent  all 
things.  Hence  by  understanding  His  essence,  God  knows 
the  essences  of  all  things,  and  also  whatever  can  be  accidental 
to  them. 

Reply  Obj.  i.  This  ol)jection  would  avail  if  God  knew 
enunciable  things  after  the  manner  of  enunciable  things. 

Reply  Obj.  2.  Enunciatory  composition  signifies  some 
existence  of  a  thing;  and  thus  God  by  His  existence,  which 
is  His  essence,  is  the  similitude  of  all  those  things  which  are 
signified  by  enunciation. 

Fifteenth  Article, 
whether  the  knowledge  of  god  is  variable  ? 

We  proceed  thus  to  the  Fifteenth  Article: — • 

Objection  i.  It  seems  that  the  knowledge  of  God  is 
variable.  For  knowledge  is  related  to  what  is  knowable. 
But  whatever  imports  relation  to  the  creature  is  applied  to 
God  from  time,  and  varies  according  to  the  variation  of 
creatures.  Therefore  the  knowledge  of  God  is  variable 
according  to  the  variation  of  creatures. 

Obj.  2.  Further,  whatever  God  can  make.  He  can  know. 
But  God  can  make  more  than  He  does.  Therefore  He  can 
know  more  than  He  knows.  Thus  His  knowledge  can  vary 
according  to  increase  and  diminution. 

Obj.  3.  Further,  God  knew  that  Christ  would  be  born. 
But  He  does  not  know  now  that  Christ  will  be  born ;  because 
Christ  is  not  to  be  born  in  the  future.  Therefore  God  does 
not  know  everythirg  He  once  knew;  and  thus  the  know- 
ledge of  God  is  variable. 

On  the  contrary,  It  is  ^  aid,  that  in  God  there  is  no  change 
nor  shadow  of  alteration  (James,  i.  17). 

I  answer  thai,  Since  the  knowledge  of  God  is  His  substance, 
as  is  clear  from  the  foregoing  (A.  4),  just  as  His  substance 
is  altogether  immutable,  as  shown  above  (Q.  IX.,  A.  i),  so 
His  knowledge  likewise  must  be  altogether  invariable. 


213  GOD'S  KNOWLEDGE  Q.  14.  Art.  15 

Reply  Obj.  1.  Lord,  Creator,  and  the  like,  import  relations 
to  creatures  in  so  far  as  they  are  in  themselves.  But  the 
knowledge  of  God  imports  relation  to  creatures  in  so  far  as 
they  are  in  God;  because  everything  is  actually  understood 
according  as  it  is  in  the  one  who  understands.  Now  created 
things  are  in  God  in  an  invariable  manner;  while  they  exist 
variably  in  themselves.  We  may  also  say  that  Lord, 
Creator,  and  the  like,  import  the  relations  consequent  upon 
the  acts  which  are  understood  as  terminating  in  the  creatures 
themselves,  as  they  are  in  themselves;  and  thus  these 
relations  are  attributed  to  God  variously,  according  to  the 
variation  of  creatures.  But  knowledge  and  love,  and  the 
like,  import  relations  consequent  upon  the  acts  which  are 
understood  to  be  in  God;  and  therefore  these  are  predicated 
of  God  in  an  invariable  manner. 

Reply  Obj.  2.  God  knows  also  what  He  can  make,  and 
does  not  make.  Hence  from  the  fact  that  He  can  make 
more  than  He  makes,  it  does  not  follow  that  He  can  know 
more  than  He  knows,  unless  this  be  referred  to  the  know- 
ledge of  vision,  according  to  which  He  is  said  to  know  those 
things  which  are  in  act  in  some  period  of  time.  But  from 
the  fact  that  He  knows  some  things  might  be  which  are  not, 
or  that  some  things  might  not  be  which  are,  it  does  not  follow 
that  His  knowledge  is  variable,  but  rather  that  He  knows 
the  variability  of  things.  If,  however,  anything  existed 
which  God  did  not  previously  know,  and  afterwards  knew, 
then  His  knowledge  would  be  variable.  But  this  could  not 
be ;  for  whatever  is,  or  can  be  in  any  period  of  time,  is  known 
by  God  in  His  eternity.  Therefore  from  the  fact  that  a 
thing  exists  in  some  period  of  time,  it  follows  that  it  is 
known  by  God  from  eternity.  Therefore  it  cannot  be 
granted  that  God  can  know  more  than  He  knows;  because 
such  a  proposition  implies  that  first  of  all  He  did  not  know, 
and  then  afterwards  knew. 

Reply  Obj.  3.  The  ancient  Nominalists  said  that  it  was 
the  same  thing  to  say  Christ  is  born  and  wil  be  born, 
and  was  born;  because  the  same  thing  i  signified  by  these 
three — viz.,  the  nativity  of  Christ.     Therefore  it  follows, 


Q.  14.  Art.  16    THE  "  SUMMA  THEOLOGICA  "  214 

they  said,  that  whatever  God  knew,  He  knows ;  because 
now  He  knows  that  Christ  is  born,  which  means  the  same 
thing  as  that  Christ  will  be  born.  This  opinion,  however, 
is  false;  both  because  the  diversity  in  the  parts  of  a 
sentence  causes  a  diversity  of  enunciations;  and  because 
it  would  follow  that  a  proposition  which  is  true  once  would 
be  always  true;  which  is  contrary  to  what  the  Philosopher 
lays  down  (Categor.  iii.)  when  he  says  that  this  sentence, 
Socrates  sits,  is  true  when  he  is  sitting,  and  false  when  he 
rises  up.  Therefore,  it  must  be  conceded  that  this  pro- 
position is  not  true.  Whatever  God  knew  He  knows,  if  referred 
to  enunciable  propositions.  But  because  of  this,  it  does  not 
follow  that  the  knowledge  of  God  is  variable.  For  as  it  is 
without  variation  in  the  divine  knowledge  that  God  knows 
one  and  the  same  thing  sometime  to  be,  and  sometime 
not  to  be,  so  it  is  without  variation  in  the  divine  knowledge 
that  God  knows  an  enunciable  proposition  is  sometime 
true,  and  sometime  false.  The  knowledge  of  God,  how- 
ever, would  be  variable  if  He  knew  enunciable  things  by 
way  of  enunciation,  by  composition  and  division,  as  occurs 
in  our  intellect.  Hence  our  knowledge  varies  either  as 
regards  truth  and  falsity,  for  example,  if  when  a  thing 
suffers  change  we  retained  the  same  opinion  about  it; 
or  as  regards  diverse  opinions,  as  if  we  first  thought  that 
anyone  was  sitting,  and  afterwards  thought  that  he  was 
not  sitting;  neither  of  which  can  be  in  God. 

Sixteenth  Article, 
whether  god  has  a  speculative  knowledge  of 

THINGS  ? 

We  proceed  thus  to  the  Sixteenth  Article  : — 

Objection  i.  It  seems  that  God  has  not  a  speculative 
knowledge  of  things.  For  the  knowledge  of  God  is  the 
cause  of  things,  as  shown  above  (A.  8).  But  speculative 
knowledge  is  not  the  cause  of  the  things  known.  Therefore 
the  knowledge  of  God  is  not  speculative. 

Ohj,  2.  Further,  speculative  knowledge  comes  by  abstrac- 


215  GOD'S  KNOWLEDGE  Q.  14.  Art.  16 

tion  from  things;  which  does  not  belong  to  the  divine 
knowledge.  Therefore  the  knowledge  of  God  is  not 
speculative. 

On  the  contrary,  Whatever  is  the  more  excellent  must  be 
attributed  to  God.  But  speculative  knowledge  is  more 
excellent  than  practical  knowledge,  as  the  Philosopher  says 
in  the  beginning  of  Metaph.  Therefore  God  has  a  specu* 
lative  knowledge  of  things. 

/  answer  that,  Some  knowledge  is  speculative  only;  some 
is  practical  only;  and  some  is  partly  speculative  and  partly 
practical.     In   proof   whereof   it   must   be   observed   that 
knowledge  can  be  called  speculative  in  three  ways:  first, 
on  the  part  of  the  things  known,  which  are  not  operable  by 
the  knower;  such  is  the  knowledge  of  man  about  natural  or 
divine  things.     Secondly,  as  regards  the  manner  of  knowing 
— as,  for  instance,  if  a  builder  consider  a  house  by  defining 
and  dividing,  and  considering  what  belongs  to  it  in  general: 
for  this  is  to  consider  operable  things  in  a  speculative 
manner,    and   not   as   practically   operable;    for   operable 
means  the  application  of    form  to  matter,   and  not  the 
resolution  of  the  composite  into  its  universal  formal  prin- 
ciples.    Thirdly,  as  regards  the  end;  /or  the  practical  intellect 
differs  in  its  end  from  the  speculative,  as  the  Philosopher 
says  (De  Anima  iii.).     For  the  practical  intellect  is  ordered 
to  the  end  of  the  operation;  whereas  the  end  of  the  specu- 
lative intellect  Is  the  consideration  of  truth.     Hence  if  a 
builder  should  consider  how  a  house  can  be  made,  not 
ordering   this  to  the  end  of  operation,  but  only  to  know 
(how  to  do  it),  this  would  be  only  a  speculative  considera- 
tion as  regards  the  end,  although  it  concerns  an  operable 
thing.     Therefore  knowledge  which  is  speculative  by  reason 
of  the  thing  itself  known,  is  merely  speculative.     But  that 
which  is  speculative  either  in  its  mode  or  as  to  its  end  is 
partly  speculative  and  partly  practical:   and  when  it  is 
ordained  to  an  operative  end  It  is  simply  practical. 

In  accordance  with  this,  therefore,  it  must  be  said  that 
God  has  of  Himself  a  speculative  knowledge  only;  for  He 
Himself  is  not  operable. 


Q.  14.  Art.  16    THE  "  SUMMA  THEOLOGICA  ''  216 

But  of  all  other  things  He  has  both  speculative  and 
practical  knowledge.  He  has  speculative  knowledge  as 
regards  the  mode;  for  whatever  we  know  speculatively  in 
things  by  defining  and  dividing,  God  knows  all  this  much 
more  perfectly. 

Now  of  things  which  He  can  make,  but  does  not  make  at 
any  time,  He  has  not  a  practical  knowledge,^  accordingly  as 
knowledge  is  called  practical  from  the  end.  But  He  has 
a  practical  knowledge  of  what  He  makes  in  some  period  of 
time.  And,  as  regards  evil  things,  although  they  are  not 
operable  by  Him,  yet  they  fall  under  His  practical  know- 
ledge, like  good  things,  inasmuch  as  He  permits,  or  impedes, 
or  directs  them;  as  also  sicknesses  fall  under  the  practical 
knowledge  of  the  physician,  inasmuch  as  he  cures  them  by 
his  art. 

Reply  Ohj.  i.  The  knowledge  of  God  is  the  cause,  not 
indeed  of  Himself,  but  of  other  things.  He  is  actually  the 
cause  of  some,  that  is,  of  things  that  come  to  be  in  some 
period  of  time;  and  He  is  virtually  the  cause  of  others,  that 
is,  of  things  which  He  can  make,  and  which  nevertheless 
are  never  made. 

Reply  Ohj.  2.  The  fact  that  knowledge  is  derived  from 
things  known  does  not  essentially  belong  to  speculative 
knowledge,  but  only  accidentally  in  so  far  as  it  is  human. 

In  answer  to  what  is  objected  on  the  contrary,  we  must 
say  that  perfect  knowledge  of  operable  things  is  .obtainable 
only  if  they  are  known  in  so  far  as  they  are  operable.  There- 
fore, since  the  knowledge  of  God  is  in  every  way  perfect. 
He  must  know  what  is  operable  by  Him,  formally  as  such, 
and  not  only  in  so  far  as  they  are  speculative.  Nevertheless 
this  does  not  impair  the  nobility  of  His  speculative  know- 
ledge, forasmuch  as  He  sees  all  things  other  than  Himself 
in  Himself,  and  He  knows  Himself  speculatively;  and  so  in 
the  speculative  knowledge  of  Himself,  He  possesses  both 
speculative  and  practical  knowledge  of  all  other  things. 


QUESTION  XV. 

OF  IDEAS. 

{In  Three  Articles.) 

After  considering  the  knowledge  of  God,  it  remains  to 
consider  ideas.  And  about  this  there  are  three  points  of 
inquiry:  (i)  Whether  there  are  ideas?  (2)  Whether  they 
are  many,  or  one  only  ?  (3)  Whether  there  are  ideas  of 
all  things  known  by  God  ? 

First  Article, 
whether  there  are  ideas? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  there  are  no  ideas.  For 
Dionysius  says  (Div.  Nom.  vii.),  that  God  does  not  know 
things  by  ideas.  But  ideas  are  for  nothing  else  except 
that  things  may  be  known  through  them.  Therefore  there 
are  no  ideas. 

Ohj.  2.  Further,  God  knows  all  things  in  Himself,  as  has 
been  already  said  (Q.  XIV.,  A.  5).  But  He  does  not  know 
Himself  through  an  idea;  neither  therefore  other  things. 

Ohj.  3.  Further,  an  idea  is  considered  to  be  the  principle 
of  knowledge  and  action.  But  the  divine  essence  is  a 
sufficient  principle  of  knowing  and  effecting  all  things.  It 
is  not  therefore  necessary  to  suppose  ideas. 

On  the  contrary,  Augustine  says  {Octog.  Tri.  Qucest.;  qu. 
xlvi.).  Such  is  the  power  inherent  in  ideas,  that  no  one  can  he 
wise  unless  they  are  understood. 

I  answer  that,  It  is  necessary  to  suppose  ideas  in  the 
divine  mind.  For  the  Greek  word  T^ea  is  in  Latin  Forma. 
Hence  by  ideas  are  understood  the  forms  of  things,  existing 

217 


Q.  15.  Art.  i    THE  "  SUMMA  THEOLOGICA  "  218 

apart  from  the  things  themselves.  Now  the  form  of  any- 
thing existing  apart  from  the  thing  itself  can  be  for  one  of 
two  ends;  either  to  be  the  type  of  that  of  which  it  is  called 
the  form,  or  to  be  the  principle  of  the  knowledge  of  that 
thing,  inasmuch  as  the  forms  of  things  knowable  are  said 
to  be  in  him  who  knows  them.  In  either  case  we  must 
suppose  ideas,  as  is  clear  for  the  following  reason : 

In  all  things  not  generated  by  chance,  the  form  must  be 
the  end  of  any  generation  whatsoever.  But  an  agent  does 
not  act  on  account  of  the  form,  except  in  so  far  as  the  like- 
ness of  the  form  is  in  the  agent,  as  may  happen  in  two  ways 
For  in  some  agents  the  form  of  the  thing  to  be  made  pre- 
exists according  to  its  natural  being,  as  in  those  that  act 
by  their  nature ;  as  a  man  generates  a  man,  or  fire  generates 
fire.  Whereas  in  other  agents  (the  form  of  the  thing  to  be 
made  pre-exists)  according  to  intelligible  being,  as  in  those 
that  act  by  the  intellect;  and  thus  the  likeness  of  a  house 
pre-exists  in  the  mind  of  the  builder.  And  this  may  be 
called  the  idea  of  the  house,  since  the  builder  intends  to 
build  his  house  like  to  the  form  conceived  in  his  mind.  As 
then  the  world  was  not  made  by  chance,  but  by  God  acting 
by  His  intellect,  as  will  appear  later  (Q.  XLVL,  A.  i),  there 
must  exist  in  the  divine  mind  a  form  to  the  likeness  of 
which  the  world  was  made.  And  in  this  the  notion  of  an 
idea  consists. 

Reply  Obj.  i.  God  does  not  understand  things  according 
to  an  idea  existing  outside  Himself.  Thus  Aristotle 
(Metaph.  ix.)  rejects  the  opinion  of  Plato,  who  held  that 
ideas  existed  of  themselves,  and  not  in  the  intellect. 

Reply  Obj.  2.  Although  God  knows  Himself  and  all  else 
by  His  own  essence,  yet  His  essence  is  the  operative  prin- 
ciple of  all  things,  except  of  Himself.  It  has  therefore  the 
nature  of  an  idea  with  respect  to  other  things;  though  not 
with  respect  to  Himself. 

Reply  Obj.  3.  God  is  the  similitude  of  all  things  according 
to  His  essence;  therefore  an  idea  in  God  is  identical  with 
His  essence. 


219  OF  IDEAS  g.  15.  Art.  2 

Second  Article, 
whether  ideas  are  many  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  ideas  are  not  many.  For  an 
idea  in  God  is  His  essence.  But  God's  essence  is  one  only. 
Therefore  there  is  only  one  idea. 

Ohj.  2.  Further,  as  the  idea  is  the  principle  of  knowing 
and  operating,  so  are  art  and  wisdom.  But  in  God  there  are 
not  several  arts  or  wisdoms.  Therefore  in  Him  there  is 
no  plurality  of  ideas. 

Ohj.  3.  Further,  if  it  be  said  that  ideas  are  multiplied 
according  to  their  relations  to  different  creatures,  it  may 
be  argued  on  the  contrary  that  the  plurality  of  ideas  is 
eternal.  If,  then,  ideas  are  many,  but  creatures  temporal, 
then  the  temporal  must  be  the  cause  of  the  eternal. 

Ohj.  4.  Further,  these  relations  are  either  real  in  creatures 
only,  or  in  God  also.  If  in  creatures  only,  since  creatures 
are  not  from  eternity,  the  plurality  of  ideas  cannot  be  from 
eternity,  if  ideas  are  multiplied  only  according  to  these 
relations.  But  if  they  are  real  in  God,  it  follows  that  there 
is  a  real  plurality  in  God  other  than  the  plurality  of  Persons : 
and  this  is  against  the  teaching  of  Damascene  (De  Fide 
Orthod.  i.  10),  who  says,  in  God  all  things  are  one,  except 
ingeiter ability,  generation,  and  procession.  Ideas  therefore 
are  not  many. 

On  the  contrary,  Augustine  says  [Octog.  Tri.  Qucest.;  qu. 
xlvi.).  Ideas  are  certain  principal  forms,  or  permanent  and 
immutable  types  of  thi^igs,  they  themselves  not  being  formed. 
Thus  they  are  eternal,  and  existing  always  in  the  same  manner, 
as  being  contained  in  the  divine  intelligence.  Whilst,  however, 
they  themselves  neither  come  into  being  nor  decay,  yet  we  say 
that  in  accordance  with  them  everything  is  formed  that  can 
arise  or  decay,  and  all  that  actually  does  so. 

I  answer  that,  It  must  necessarily  be  held  that  ideas  are 
many.  In  proof  of  which  it  is  to  be  considered  that  in 
every  effect  the  ultimate  end  is  the  proper  intention  of  the 


Q.  15.  Art.  2    THE    '  SUMMA  THEOLOGICA  ''  220 

principal  agent,  as  the  order  of  an  army  (is  the  proper 
intention)  of  the  general.  Now  the  highest  good  exist- 
ing in  things  is  the  good  of  the  order  of  the  universe, 
as  the  Philosopher  clearly  teaches  in  Mefaph.  xii.  There- 
fore the  order  of  the  universe  is  properly  intended  by  God, 
and  is  not  the  accidental  result  of  a  succession  of  agents, 
as  has  been  supposed  by  those  who  have  taught  that  God 
created  only  the  first  creature,  and  that  this  creature 
created  the  second  creature,  and  so  on,  until  this  great 
multitude  of  beings  was  produced.  According  to  this 
opinion  God  would  have  the  idea  of  the  first  created  thing 
alone ;  whereas,  if  the  order  itself  of  the  universe  was  created 
by  Him  immediately,  and  intended  by  Him,  He  must  have 
the  idea  of  the  order  of  the  universe.  Now  there  cannot 
be  an  idea  of  any  whole,  unless  particular  ideas  are  had  of 
those  parts  of  which  the  whole  is  made;  just  as  a  builder 
cannot  conceive  the  idea  of  a  house  unless  he  has  the  idea 
of  each  of  its  parts.  So,  then,  it  must  needs  be  that  in  the 
divine  mind  there  are  the  proper  ideas  of  all  things.  Hence 
Augustine  says  [Octog.  Tri.  Qucest.;  qu.  xlvi.),  that  each  thing 
was  created  by  God  according  to  the  idea  proper  to  if,  from 
which  it  follows  that  in  the  divine  mind  ideas  are  many. 
Now  it  can  easily  be  seen  how  this  is  not  repugnant  to  the 
simplicity  of  God,  if  we  consider  that  the  idea  of  a  work 
is  in  the  mind  of  the  operator  as  that  which  is  understood, 
and  not  as  the  image  whereby  he  understands,  which  is  a 
form  that  makes  the  intellect  in  act.  For  the  form  of  the 
house  in  the  mind  of  the  builder,  is  something  understood 
by  him,  to  the  likeness  of  which  he  forms  the  house  in 
matter.  Now,  it  is  not  repugnant  to  the  simplicity  of  the 
divine  mind  that  it  understand  many  things;  though  it 
would  be  repugnant  to  its  simplicity  were  His  understanding 
to  be  formed  by  a  plurality  of  images.  Hence  many  ideas 
exist  in  the  divine  mind,  as  things  understood  by  it;  as 
can  be  proved  thus.  Inasmuch  as  He  knows  His  own 
essence  perfectly,  He  knows  it  according  to  every  mode  in 
which  it  can  be  known.  Now  it  can  be  known  not  only  as 
it  is  in  itself,  but  as  it  can  be  participated  in  by  creatures 


221  OF  IDEAS  Q.  15.  Art.  2 

according  to  some  degree  of  likeness.  But  every  creature 
has  its  own  proper  species,  according  to  which  it  participates 
in  some  degree  in  Hkeness  to  the  divine  essence.  So  far, 
therefore,  as  God  knows  His  essence  as  capable  of  such 
imitation  by  any  creature,  He  knows  it  as  the  particular 
type  and  idea  of  that  creature:  and  in  like  manner  as 
regards  other  creatures.  So  it  is  clear  that  God  under- 
stands many  particular  types  of  many  things,  and  these 
are  many  ideas. 

Reply  Ohj.  i.  The  divine  essence  is  not  called  an  idea 
in  so  far  as  it  is  that  essence,  but  only  in  so  far  as  it  is  the 
likeness  or  type  of  this  or  that  thing.  Hence  ideas  are 
said  to  be  many,  inasmuch  as  many  types  are  understood 
through  the  self -same  essence. 

Reply  Ohj.  2.  By  wisdom  and  art  we  signify  that  by  which 
God  understands ;  but  an  idea,  that  which  God  understands. 
For  God  by  one  understands  many  things,  and  that  not 
only  according  to  what  they  are  in  themselves,  but  also 
according  as  they  are  understood,  and  this  is  to  understand 
the  several  types  of  things.     In  the  same  way,  an  architect 
is  said  to  understand  a  house,  when  he  understands  the 
form  of  the  house  in  matter.    But  if  he  understands  the  form 
of  a  house,  as  devised  by  himself,  from  the  fact  that  he 
understands  that  he  understands  it,  he  thereby  understands 
the  type  or  the  idea  of  the  house.    Now  not  only  does  God 
understand  many  things  by  His  essence,  but  He  also  under- 
stands that  He  understands  many  tilings  by  His  essence. 
And  this  means  that  He  understands  the  several  types  of 
things ;  or  that  many  ideas  are  in  His  intellect  as  understood 
by  Him. 

Reply  Ohj,  3.  Such  relations,  whereby  ideas  are  multiplied, 
are  caused  not  by  the  things  themselves,  but  by  the  divine 
intellect  comparing  its  own  essence  with  these  things. 

Reply  Ohj.  4.  Relations  multiplying  ideas  do  not  exist  in 
created  things,  but  in  God.  Yet  they  are  not  real  relations, 
such  as  those  whereby  the  Persons  are  distinguished,  but 
relations  understood  by  God,

Third  Article, 
whether  there  are  ideas  of  all  things  that  god 

KNOWS  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  there  are  not  ideas  in  God 
of  all  things  that  He  knows.  For  the  idea  of  evil  is  not  in 
God;  since  it  would  follow  that  evil  was  in  Him.  But  evil 
things  are  known  by  God.  Therefore  there  are  not  ideas 
of  all  things  that  God  knows. 

Ohj.  2.  Further,  God  knows  things  that  neither  are,  nor 
will  be,  nor  have  been,  as  has  been  said  above  (A.  9).  But  of 
such  things  there  are  no  ideas,  since,  as  Dionysius  says 
{Div,  Nom.  v.):  Acts  of  the  divine  will  are  the  determining 
and  effective  types  of  things.  Therefore  there  are  not  in  God 
ideas  of  all  things  known  by  him. 

Ohj.  3.  Further,  God  knows  primary  matter,  of  which  there 
can  be  no  idea,  since  it  has  no  form .  Hence  the  same  conclusion . 

Ohj.  4.  Further,  it  is  certain  that  God  knows  not  only 
species,  but  also  genera,  singulars,  and  accidents.  But 
there  are  no  ideas  of  these,  according  to  Plato's  teaching, 
who  first  taught  ideas,  as  Augustine  says  (Octog.  Tri. 
QticBst.;  qu.  xlvi.).  Therefore  there  are  not  ideas  in  God  of 
all  things  known  by  Him. 

On  the  contrary,  Ideas  are  types  existing  in  the  divine 
mind,  as  is  clear  from  Augustine  (ihid.).  But  God  has  the 
proper  types  of  all  things  that  He  knows;  and  therefore 
He  has  ideas  of  all  things  known  by  Him. 

/  answer  that,  As  ideas,  according  to  Plato,  are  principles 
of  the  knowledge  of  things  and  of  their  generation,  an  idea 
has  this  twofold  office,  as  it  exists  in  the  mind  of  God. 
So  far  as  the  idea  is  the  principle  of  the  making  of  things, 
it  may  be  called  an  exemplar,  and  belongs  to  practical 
knowledge.  But  so  far  as  it  is  a  principle  of  knowledge, 
it  is  properly  called  a  type,  and  may  belong  to  speculative 
knowledge  also.  As  an  exemplar,  therefore,  it  has  respect 
to  everything  made  by  God  in  any  period  of  time;  whereas 
as  a  principle  of  knowledge  it|has  respect  to  all  things  known 


2-23  OF  IDEAS  Q.  15.  Art.  3 

by  God,  even  though  they  never  come  to  be  in  time ;  and  to 
all  things  that  He  knows  according  to  their  proper  type,  in 
so  far  as  they  are  known  by  Him  in  a  speculative  manner. 

Reply  Obj.  i.  Evil  is  known  by  God  not  through  its  own 
type,  but  through  the  type  of  good.  Evil,  therefore,  has 
no  idea  in  God,  neither  in  so  far  as  an  idea  is  an  exemplar, 
nor  as  a  type. 

Reply  Obj.  2.  God  has  no  practical  knowledge,  except 
virtually,  of  things  which  neither  are,  nor  will  be,  nor  have 
been.  Hence,  with  respect  to  these  there  is  no  idea  in 
God  in  so  far  as  idea  signifies  an  exemplar,  but  only  in  so 
far  as  it  denotes  a  type. 

Reply  Obj.  3.  Plato  is  said  by  some  to  have  considered 
matter  as  not  created;  and  therefore  he  postulated  not  an 
idea  of  matter  but  a  concause  with  matter.  Since,  how- 
ever, we  hold  matter  to  be  created  by  God,  though  not 
apart  from  form,  matter  has  its  idea  in  God;  but  not  apart 
from  the  idea  of  the  composite;  for  matter  in  itself  can 
neither  exist,  nor  be  known. 

Reply  Obj.  4.  Genus  can  have  no  idea  apart  from  the 
idea  of  species,  in  so  far  as  idea  denotes  an  exemplar  ;  for 
genus  cannot  exist  except  in  some  species.  The  same  is 
the  case  with  those  accidents  that  inseparably  accompany 
their  subject;  for  these  come  into  being  along  with  their 
subject.  But  accidents  which  supervene  to  the  subject, 
have  their  special  idea.  For  an  architect  produces  through 
the  form  of  the  house  all  the  accidents  that  originally 
accompany  it;  whereas  those  that  are  superadded  to  the 
house  when  completed,  such  as  painting,  or  any  other  such 
thing,  are  produced  through  some  other  form.  Now  indi- 
vidual things,  according  to  Plato,  have  no  other  idea  than 
that  of  the  species;  both  because  particular  things  are 
individualized  by  matter,  which,  as  some  say,  he  held  to  be 
uncreated  and  the  concause  with  the  idea ;  and  because  the 
intention  of  nature  regards  the  species,  and  produces  indi- 
viduals only  that  in  them  the  species  may  be  preserved. 
However,  divine  providence  extends  not  merely  to  species; 
but  to  individuals,  as  will  be  shown  later  (Q.XXH.,  A.  3). 


QUESTION  XVI 

OF  TRUTH. 
{In  Eight  Articles.) 

Since  knowledge  is  of  things  that  are  true,  after  the  con- 
sideration of  the  knowledge  of  God,  we  must  inquire  con- 
cerning truth.  About  this  there  are  eight  points  of  inquiry : 
(i)  Whether  truth  resides  in  the  thing,  or  only  in  the  intel- 
lect ?  (2)  Whether  it  resides  only  in  the  intellect  composing 
and  dividing  ?  (3)  On  the  comparison  of  the  true  to  being. 
(4)  On  the  comparison  of  the  true  to  the  good.  (5)  Whether 
God  is  truth  ?  (6)  Whether  all  things  are  true  by  one 
truth,  or  by  many  ?  (7)  On  the  eternity  of  truth.  (8)  On 
the  unchangeableness  of  truth. 

First  Article, 
whether  truth  resides  only  in  the  intellect  ? 

We  proceed  thiis  to  the  First  Article  : — 

Objection  i.  It  seems  that  truth  does  not  reside  only  in 
the  intellect,  but  rather  in  things.  For  Augustine  {Soliloq, 
ii.  5)  condemns  this  definition  of  truth,  That  is  true  which 
is  seen  ;  since  it  would  follow  that  stones  hidden  in  the 
bosom  of  the  earth  would  not  be  true  stones,  as  they  are 
not  seen.  He  also  condemns  the  following,  That  is  tnie 
which  is  as  it  appears  to  the  knower,  who  is  willing  and  able 
to  know,  for  hence  it  would  follow  that  nothing  would  be 
true,  unless  someone  could  know  it.  Therefore  he  defines 
truth  thus:  That  is  true  which  is.  It  seems,  then,  that  truth 
resides  in  things,  and  not  in  the  intellect. 

Obj.  2.  Further,  whatever  is  true,  is  true  by  reason  of 
truth.  If,  then,  truth  is  only  in  the  intellect,  nothing  will 
be  true  except  in  so  far  as  it  is  understood.     But  this  is 

224 


225  CONCERNING  TRUTH  Q.  i6.  Art.  i 

the  error  of  the  ancient  philosophers,  who  said  that  what- 
ever seems  to  be  true  is  so.  Consequently  mutual  contra- 
dictories can  be  true  at  the  same  time,  since  contradictories 
seem  to  be  true  as  seen  by  different  persons  at  the  same 
time. 

Ohj.  3.  Further,  that,  on  account  of  which  a  thing  is  so, 
is  itself  more  so,  as  is  evident  from  the  Philosopher  {Poster,  i.). 
But  it  is  from  the  fact  that  a  thing  is  or  is  not,  that  our 
thought  or  word  is  true  or  false,  as  the  Philosopher  teaches 
{Prcedicam.  iii.).  Therefore  truth  resides  rather  in  things 
than  in  the  intellect. 

On  the  contrary,  The  Philosopher  says  {Metaph.  vi.),  The 
trite  and  the  false  reside  not  in  things,  hut  in  the  intellect. 

I  answer  that.  As  the  good  denotes  that  towards  which 
the  appetite  tends,  so  the  true  denotes  that  towards  which 
the  intellect  tends.  Now  there  is  this  difference  between 
the  appetite  and  the  intellect,  or  any  knowledge  whatsoever, 
that  knowledge  is  according  as  the  thing  known  is  in  the 
knower,  whilst  appetite  is  according  as  the  desirer  tends 
towards  the  thing  desired.  Thus  the  term  of  the  appetite, 
namely  good,  is  in  the  object  desirable,  and  the  term  of 
the  intellect,  namely  true,  is  in  the  intellect  itself.  Now  as 
good  exists  in  a  thing  so  far  as  that  thing  is  related  to  the 
appetite — and  hence  the  aspect  of  goodness  passes  on  from 
the  desirable  thing  to  the  appetite,  in  so  far  as  the  appetite 
is  called  good  if  its  object  is  good;  so,  since  the  true  is 
in  the  intellect  in  so  far  as  it  is  conformed  to  the  object 
understood,  the  aspect  of  the  true  must  needs  pass  from  the 
intellect  to  the  object  understood,  so  that  also  the  thing 
understood  is  said  to  be  true  in  so  far  as  it  has  some  relation 
to  the  intellect.  Now  a  thing  understood  may  be  in  relation 
to  an  intellect  either  essentially  or  accident aUy.  It  is 
related  essentially  to  an  intellect  on  which  it  depends  as 
regards  its  essence;  but  accidentally  to  an  intellect  by 
which  it  is  knowable;  even  as  we  may  say  that  a  house  is 
related  essentially  to  the  intellect  of  the  architect,  but 
accidentally  to  the  intellect  upon  which  it  does  not  depend. 

Now  we  do  not  judge  of  a  thing  by  what  is  in  it  accident- 

15 


g.  16.  Art.  i    THE  "  SUMMA  THEOLOGICA  "  226 

ally,  but  by  what  is  in  it  essentially.  Hence,  everything 
is  said  to  be  true  absolutely,  in  so  far  as  it  is  related  to 
the  intellect  from  which  it  depends;  and  thus  it  is  that 
artificial  things  are  said  to  be  true  as  being  related 
to  our  intellect.  For  a  house  is  said  to  be  true  that  ex- 
presses the  likeness  of  the  form  in  the  architect's  mind; 
and  words  are  said  to  be  true  so  far  as  they  are  the  signs 
of  truth  in  the  intellect.  In  the  same  way  natural  things 
are  said  to  be  true  in  so  far  as  they  express  the  likeness 
of  the  species  that  are  in  the  divine  mind.  For  a  stone 
is  called  true,  which  possesses  the  nature  proper  to  a  stone, 
according  to  the  preconception  in  the  divine  intellect.  Thus, 
then,  truth  resides  primarily  in  the  intellect,  and  secondarily 
in  things  according  as  they  are  related  to  the  intellect  as 
their  principle.  Consequently  there  are  various  definitions 
of  truth.  Augustine  says  (De  Vera  Relig.  xxxvi.).  Truth  is 
that  whereby  is  made  manifest  that  which  is  ;  and  Hilary  says 
(De  Trin.  v.)  that  Truth  makes  being  clear  and  evident: 
and  this  pertains  to  truth  according  as  it  is  in  the  intellect. 
As  to  the  truth  of  things  in  so  far  as  they  are  related  to 
the  intellect,  we  have  Augustine's  definition  (loc.  cit.), 
Truth  is  a  supreme  likeness  without  any  unlikeness  to  a 
principle:  also  Anselm's  definition  [De  Verit.  xii.),  Truth 
is  rightness,  perceptible  by  the  mind  alone  ;  for  that  is  right 
which  is  in  accordance  with  the  principle;  also  Avicenna's 
definition  (Metaph.  viii.  6),  The  truth  of  each  thing  is  a 
property  of  the  essence  which  is  immutably  attached  to  it.  The 
definition  that  Truth  is  the  equation  of  thoughi  and  thing  is 
applicable  to  it  under  either  aspect. 

Reply  Obj.  i.  Augustine  is  speaking  about  the  truth  of 
things,  and  excludes  from  the  notion  of  this  truth,  relation 
to  our  intellect;  for  what  is  accidental  is  excluded  from 
every  definition. 

Reply  Obj.  2.  The  ancient  philosophers  held  that  the 
species  of  natural  things  did  not  proceed  from  any  intellect, 
but  were  produced  by  chance.  But  as  they  saw  that  truth 
implies  relation  to  intellect,  they  were  compelled  to  base 
the  truth  of  things  on  their  relation  to  our  intellect.     From 


227  CONCERNING  TRUTH  Q.  16.  Art.  2 

this,  conclusions  result  that  are  inadmissible,  and  which  the 
Philosopher  refutes  {Metaph.  iv.).  Such,  however,  do  not 
follow,  if  we  say  that  the  truth  of  things  consists  in  their 
relation  to  the  divine  intellect. 

Reply  Ohj.  3.  Although  the  truth  of  our  intellect  is  caused 
by  the  thing,  yet  it  is  not  necessary  that  truth  should  be 
there  primarily,  any  more  than  that  health  should  be 
primarily  in  medicine,  rather  than  in  the  animal:  for  the 
virtue  of  medicine,  and  not  its  health,  is  the  cause  of  health, 
for  here  the  agent  is  not  univocal.  In  the  same  way  the 
being  of  the  thing,  not  its  truth,  is  the  cause  of  truth  in  the 
intellect.  Hence  the  Philosopher  says  that  a  thought  or 
word  is  true  from  the  fact  that  a  thing  is,  not  because  a  thing 
is  true. 

Second  Article. 

whether  truth  resides  only  in  the  intellect 
composing  and  dividing  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  truth  does  not  reside  only  in 
the  intellect  composing  and  dividing.  For  the  Philosopher 
says  [De  Anima  iii.)  that  as  the  senses  are  always  true  as 
regards  their  proper  sensible  objects,  so  is  the  intellect  as 
regards  what  a  thing  is.  Now  composition  and  division  are 
neither  in  the  senses  nor  in  the  intellect  knowing  what  a 
thing  is.  Therefore  truth  does  not  reside  only  in  the  intellect 
composing  and  dividing. 

Obj.  2.  Further,  Isaac  says  in  his  book  On  Definitions  that, 
truth  is  the  equation  of  thought  and  thing.  Now  just  as. 
the  intellect  with  regard  to  complex  things  can  be  equated 
to  things,  so  also  with  regard  to  simple  things;  and  this  is 
true  also  of  sense  apprehending  a  thing  as  it  is.  Therefore 
truth  does  not  reside  only  in  the  intellect  composing  and 
dividing. 

On  the  contrary,  the  Philosopher  says  {Metaph.  vi.)  that 
with  regard  to  simple  things  and  what  a  thing  is,  truth  is 
found  neither  in  the  intellect  nor  in  things. 

I  answer  that,  As  stated  before,  truth  resides,  in  its  primary 


Q.  16.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  228 

aspect,   in   the  intellect.     Now   since   ever5^hing  is   true 
according  as  it  has  the  form  proper  to  its  nature,  the  intel- 
lect, in  so  far  as  it  is  knowing,  must  be  true,  so  far  as  it  has 
the  likeness  of  the  thing  known,  this  being  its  form,  as 
knowing.     For  this  reason  truth  is  defined  by  the  con- 
formity of  intellect  and  thing;  and  hence  to  know  this 
conformity  is  to  know  truth.    But  in  no  way  can  sense 
know  this.     For  although  sight  has  the  likeness  of  a  visible 
thing,  yet  it  does  not  know  the  comparison  which  exists 
between  the  thing  seen  and  that  which  itself  apprehends 
concerning  it.     But  the  intellect  can  know  its  own  con- 
formity with  the  intelUgible  thing;  yet  it  does  not  appre- 
hend it  by  knowing  of  a  thing  what  a  thing  is.     When, 
however,  it  judges  that  a  thing  corresponds  to  the  form 
which  it  apprehends  about  that  thing,  then  first  it  knows 
and   expresses   truth.     This   it   does   by   composing   and 
dividing:  for  in  every  proposition  it  either  applies  to,  or 
removes  from  the  thing  signified  by  the  subject,  some  form 
signified  by  the  predicate:  and  this  clearly  shows  that  the 
sense  is  true  of  any  thing,  as  is  also  the  intellect,  when  it 
knows  what  a  thing  is;  but  it  does  not  thereby  know  or 
affirm  truth.    This  is  in  like  manner  the  case  with  complex 
or  non-complex  words.     Truth   therefore  may  be  in  the 
senses,  or  in  the  intellect  knowing  what  a  thing  is,  as  in 
anything  that  is  true;  yet  not  as  the  thing  known  in  the 
knower,  which  is  implied  by  the  word  truth  ;  for  the  per- 
fection  of   the   intellect   is   truth   as   known.     Therefore, 
properly  speaking,  truth  resides  in  the  intellect  composing 
and  dividing;  and  not  in  the  senses;  nor  in  the  intellect 
knowing  what  a  thing  is. 

And  thus  the  Objections  given  are  solved. 

Third  Article, 
whether  the  true  and  being  are  convertible  terms  ? 

We  proceed  thus  to  the  Third  Article  : — 
Ohjectiofi  I.  It  seems  that  the  true  and  being  are  not 
convertible  terms.    For  the  true  resides  properly  in  the 


229  CONCERNING  TRUTH  Q.  i6.  Art.  3 

intellect,  as  stated  (A.  i);  but  being  is  properly  in  things. 
Therefore  they  are  not  convertible. 

Ohj.  2.  Further,  that  which  extends  to  being  and  not- 
being  is  not  convertible  with  being.  But  the  true  extends 
to  being  and  not-being;  for  it  is  true  that  what  is,  is;  and 
that  what  is  not,  is  not.  Therefore  the  true  and  being  are 
not  convertible. 

Ohj.  3.  Further,  things  which  stand  to  each  other  in  order 
of  priority  and  posteriority  seem  not  to  be  convertible.  But 
the  true  appears  to  be  prior  to  being;  for  being  is  not  under- 
stood except  under  the  aspect  of  the  true.  Therefore  it 
seems  they  are  not  convertible. 

On  the  contrary,  the  Philosopher  says  (Metaph.  ii.)  that 
there  is  the  same  disposition  of  things  in  being  and  in  truth. 

/  answer  that,  As  good  has  the  nature  of  what  is  desir- 
able, so  truth  is  related  to  knowledge.  Now  everything, 
in  as  far  as  it  has  being,  so  far  is  it  knowable.  Wherefore  it 
is  said  in  De  Anima  iii.  that  the  soul  is  in  some  manner  all 
things,  through  the  senses  and  the  intellect.  And  therefore, 
as  good  is  convertible  with  being,  so  is  the  true.  But  as  good 
adds  to  being  the  notion  of  desirable,  so  the  true  adds 
relation  to  the  intellect. 

Reply  Ohj.  i.  The  true  resides  in  things  and  in  the  intel- 
lect, as  said  before  (A.  i).  But  the  true  that  is  in  things 
is  convertible  with  being  as  to  substance;  while  the  true 
that  is  in  the  intellect  is  convertible  with  being,  as  the 
manifestation  with  the  manifested;  for  this  belongs  to  the 
nature  of  truth,  as  has  been  said  already  {ibid.).  It  may, 
however,  be  said,  that  being  also  is  in  things  and  in  the 
intellect,  as  is  the  true;  although  truth  is  primarily  in  the 
intellect,  while  being  is  primarily  in  things;  and  this  is  so 
because  truth  and  being  differ  in  idea. 

Reply  Ohj.  2.  Not-being  has  nothing  in  itself  whereby  it 
can  be  known;  yet  it  is  known  in  so  far  as  the  intellect 
renders  it  knowable.  Hence  the  true  is  based  on  being, 
inasmuch  as  not-being  is  a  kind  of  logical  being,  appre- 
hended, that  is,  by  reason. 

Reply  Ohj.  3.  When  it  is  said  that  being  cannot  be  appre- 


Q.  i6.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  230 

hended  except  under  the  notion  of  the  true,  this  can  be 
understood  in  two  ways.  In  the  one  way  so  as  to  mean 
that  being  is  not  apprehended,  unless  the  idea  of  the  true 
follows  apprehension  of  being;  and  this  is  true.  In  the 
other  way,  so  as  to  mean  that  being  cannot  be  apprehended 
unless  the  idea  of  the  true  be  apprehended  also;  and  this 
is  false.  But  the  true  cannot  be  apprehended  unless  the 
idea  of  being  be  apprehended  also;  since  being  is  included 
in  the  idea  of  the  true.  The  case  is  the  same  if  we  compare 
the  intelligible  object  with  being.  For  being  cannot  be 
understood,  unless  being  is  intelligible.  Yet  being  can  be 
understood  while  its  intelligibility  is  not  understood. 
Similarly,  being  when  understood  is  true,  yet  the  true  is 
not  understood  by  understanding  being. 

Fourth  Article, 
whether  good  is  logically  prior  to  the  true  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  good  is  logically  prior  to  the 
true.  For  what  is  more  universal  is  logically  prior,  as  is 
evident  from  Physic,  i.  But  the  good  is  more  universal  than 
the  true,  since  the  true  is  a  kind  of  good,  namely,  of  the 
intellect.     Therefore  the  good  is  logically  prior  to  the  true. 

Ohj.  2.  Further,  good  is  in  things,  but  the  true  in  the 
intellect  composing  and  dividing,  as  said  before  (A.  2).  But 
that  which  is  in  things  is  prior  to  that  which  is  in  the 
intellect.     Therefore  good  is  logically  prior  to  the  true. 

Ohj.  3.  Further,  truth  is  a  species  of  virtue,  as  is  clear 
from  Ethic,  iv.  But  virtue  is  included  under  good;  since, 
as  Augustine  says  [De  Lib.  Arbit.  ii.  19),  it  is  a  good  quality 
of  the  mind.     Therefore  the  good  is  prior  to  the  true. 

On  the  contrary,  What  is  in  more  things  is  prior  logically. 
But  the  true  is  in  some  things  wherein  good  is  not,  as,  for 
instance,  in  mathematics.  Therefore  the  true  is  prior  to 
good. 

I  answer  that,  Although  the  good  and  the  true  are  con- 
vertible  with   being,    as   to   suppositum,    yet    they   differ 


231  CONCERNING  TRUTH  Q.  i6.  Art.  4 

logically.  And  in  this  manner  the  true,  speaking  absolutely, 
is  prior  to  good,  as  appears  from  two  reasons.  First, 
because  the  true  is  more  closely  related  to  being  than  is 
good.  For  the  true  regards  being  itself  simply  and  im- 
mediately; while  the  nature  of  good  follows  being  in  so  far 
as  being  is  in  some  way  perfect;  for  thus  it  is  desirable. 
Secondly,  it  is  evident  from  the  fact  that  knowledge  naturally 
precedes  appetite.  Hence,  since  the  true  regards  know- 
ledge, but  the  good  regards  the  appetite,  the  true  must  be 
prior  in  idea  to  the  good. 

Reply  Obj.  i.  The  will  and  the  intellect  mutually  include 
one  another:  for  the  intellect  understands  the  will,  and  the 
will  wills  the  intellect  to  understand.  So  then,  among 
things  directed  to  the  object  of  the  will,  are  comprised  also 
those  that  belong  to  the  intellect ;  and  conversely.  Whence 
in  the  order  of  things  desirable,  good  stands  as  the  universal, 
and  the  true  as  the  particular;  whereas  in  the  order  of 
intelligible  things  the  converse  is  the  case.  From  the  fact, 
then,  that  the  true  is  a  kind  of  good,  it  follows  that  the  good 
is  prior  in  the  order  of  things  desirable;  but  not  that  it  is 
prior  absolutely. 

Reply  Obj.  2.  A  thing  is  prior  logically  in  so  far  as  it  is 
prior  to  the  intellect.  Now  the  intellect  apprehends 
primarily  being  itself;  secondly,  it  apprehends  that  it 
understands  being;  and  thirdly,  it  apprehends  that  it 
desires  being.  Hence  the  idea  of  being  is  first,  that  of 
truth  second,  and  the  idea  of  good  third,  though  good  is 
in  things. 

Reply  Obj.  3.  The  virtue  which  is  called  truth  is  not  truth 
in  general,  but  a  certain  kind  of  truth  according  to  which 
man  shows  himself  in  deed  and  word  as  he  really  is.  But 
truth  as  applied  to  life  is  used  in  a  particular  sense,  inasmuch 
as  a  man  fulfils  in  his  life  that  to  which  he  is  ordained  by 
the  divine  intellect,  as  it  has  been  said  that  truth  exists 
in  other  things  (A.  i).  Whereas  the  truth  of  justice  is  found 
in  man  as  he  fulfils  his  duty  to  his  neighbour,  as  ordained  by 
law.  Hence  we  cannot  argue  from  these  particular  truths 
to  truth  in  general.

Fifth  Article, 
whether  god  is  truth  ? 

We  proceed  thus  to  the  Fifth  Article  : — 

Objection  i.  It  seems  that  God  is  not  truth.  For  truth 
consists  in  the  intellect  composing  and  dividing.  But  in 
God  there  is  not  composition  and  division.  Therefore  in 
Him  there  is  not  truth. 

Ohj,  2.  Further,  truth,  according  to  Augustine  [De  Vera 
Relig.  xxxvi.),  is  a  likeness  to  the  principle.  But  in  God 
there  is  no  likeness  to  a  principle.  Therefore  in  God  there 
is  not  truth. 

Obj.  3.  Further,  whatever  is  said  of  God,  is  said  of  Him 
as  of  the  first  cause  of  all  things ;  thus  the  being  of  God  is  the 
cause  of  all  being;  and  His  goodness  the  cause  of  all  good. 
If  therefore  there  is  truth  in  God,  all  truth  will  be  from 
Him.  But  it  is  true  that  someone  sins.  Therefore  this 
will  be  from  God;  which  is  evidently  false. 

On  the  contrary,  Our  Lord  says,  I  am  the  Way,  the  Truth 
and  the  Life  (John  xiv.  6). 

I  answer  that,  As  said  above  (A.  i),  truth  is  found  in  the 
intellect  according  as  it  apprehends  a  thing  as  it  is;  and  in 
things  according  as  they  have  being  conformable  to  an  in- 
tellect. This  is  to  the  greatest  degree  found  in  God.  For  His 
being  is  not  only  conformed  to  His  intellect,  but  it  is  the 
very  act  of  His  intellect;  and  His  act  of  understanding  is 
the  measure  and  cause  of  every  other  being  and  of  every 
other  intellect,  and  He  Himself  is  His  own  existence  and 
act  of  understanding.  Whence  it  follows  not  only  that  is 
truth  in  Him,  but  that  He  is  truth  itself,  and  the  sovereign 
and  first  truth. 

Reply  Obj.  i.  Although  in  the  divine  intellect  there  is 
neither  composition  nor  division,  yet  in  His  simple  act  of 
intelligence  He  judges  of  all  things  and  knows  all  things 
complex;  and  thus  there  is  truth  in  His  intellect. 

Reply  Obj.  2.  The  truth  of  our  intellect  is  according  to  its 
conformity  with  its  principle,  that  is  to  say,  to  the  things 


233  CONCERNING  TRUTH  Q.  i6.  Art.  6 

from  which  it  receives  knowledge.  The  truth  also  of  things 
is  according  to  their  conformity  with  their  principle,  namely, 
the  divine  intellect.  Now  this  cannot  be  said,  properly 
speaking,  of  divine  truth;  unless  perhaps  in  so  far  as  truth 
is  appropriated  to  the  Son,  Who  has  a  principle.  But  if  we 
speak  of  divine  truth  in  its  essence,  we  cannot  understand  this 
unless  the  affirmative  must  be  resolved  into  the  negative, 
as  when  one  says :  the  Father  is  of  Himself,  because  He  is  not 
from  another.  Similarly,  the  divine  truth  can  be  called  a 
likeness  to  the  principle,  inasmuch  as  His  existence  is  not 
dissimilar  to  His  intellect. 

Reply  Obj.  3.  Not-being,  and  privation,  have  no  truth  of 
themselves,  but  only  in  the  apprehension  of  the  intellect. 
Now  all  apprehension  of  the  intellect  is  from  God.  Hence 
all  the  truth  that  exists  in  the  statement, — that  a  person 
commits  fornication  is  true,  is  entirely  from  God.  But  to 
argue.  Therefore  that  this  person  fornicates  is  from  God,  is  a 
fallacy  of  Accident. 

Sixth  Article. 

whether  there  is  only  one  truth,  according  to 
which  all  things  are  true  ? 

We  proceed  thus  to  the  Sixth  Article  : — 

Objection  i.  It  seems  that  there  is  only  one  truth,  ac- 
cording to  which  all  things  are  true.  For  according  to 
Augustine  (De  Trin.  xv.  i),  nothing  is  greater  than  the 
mind  of  man,  except  God.  Now  truth  is  greater  than  the 
mind  of  man;  otherwise  the  mind  would  be  the  judge  of 
truth:  whereas  in  fact  it  judges  all  things  according  to  truth, 
and  not  according  to  its  own  measure.  Therefore  God 
alone  is  truth.     Therefore  there  is  no  other  truth  but  God. 

Obj.  2.  Further,  Anselm  says  {De  Verit.  xiv.),  that,  as  is 
the  relation  of  time  to  temporal  things,  so  is  that  of  truth 
to  true  things.  But  there  is  only  one  time  for  all  temporal 
things.  Therefore  there  is  only  one  truth,  by  which  all 
things  are  true. 

On  the  contrary,  it  is  written  (Ps.  xi.  2),  Truths  are  decayed 
from  among  the  children  of  men. 


Q.  16.  Art.  6    THE  "  SUMMA  THEOLOGICA  "  234 

/  answer  that,   In  one  sense  truth,   whereby  all  things 
are  true  is  one,  and  in  another  sense  it  is  not.     In  proof 
of  which  we  must  consider  that  when  anything  is  predicated 
of  many  things  univocally,  it  is  found  in  each  of   them 
according  to  its  proper  nature;  as  animal  is  found  in  each 
species  of  animal.     But  when  anything  is  predicated  of 
many  things  analogically,  it  is  found  in  only  one  of  them 
according  to  its  proper  nature,  and  from  this  one  the  rest 
are  denominated.     So  healthiness  is  predicated  of  animal,  of 
Vnne,  and  of  medicine,  not  that  health  is  only  in  the  animal; 
but  from  the  health  of  the  animal,  medicine  is  called  healthy, 
in  so  far  as  it  is  the  cause  of  health,  and  urine  is  called 
healthy,  in  so  far  as  it  indicates   health.     And  although 
health  is  neither  in  medicine  nor  in  urine,    yet   in  either 
there  is  something  whereby  the  one  causes,  and  the  other 
indicates  health.     Now  we  have  said  (A.  i)  that  truth  resides 
primarily  in  the  intellect ;  and  secondarily  in  things,  accord- 
ing as  they  are  related  to  the  divine  intellect.     If  therefore 
we  speak  of  truth,  as  it   exists  in  the  intellect,  according 
to  its  proper  nature,  then  are  there  many  truths  in  many 
created  intellects;  and  even  in  one  and  the  same  intellect, 
according   to    the  number  of    things   known.     Whence  a 
gloss   on  Ps.    xi.    2,    Truths    are   decayed  from   among  the 
children    of  men,    says  :    As  from    one    man's  face    many 
likenesses   are   reflected   in   a   mirror,   so   many   truths   are 
reflected  from   the  one   divine   truth.     But  if  we  speak  of 
truth  as  it  is  in  things,  then   all  things   are  true  by  one 
primary  truth;  to  which  each  one  is  assimilated  according 
to  its  own   entity.     And  thus,   although    the   essences  or 
forms  of  things  are  many,  yet  the  truth  of  the  divine  intellect 
is  one,  in  conformity  to  which  all  things  are  said  to  be  true. 
Reply  Ohj.  i.  The  soul  does  not  judge  of  all  things  accord- 
ing to  any  kind  of  truth,  but  according   to   the  primary 
truth,  inasmuch  as  it  is  reflected  in  the  soul,  as  in  a  mirror, 
by  reason  of  the  first  principles  of  the  understanding.     It 
follows,  therefore,  that  the  primary  truth  is  greater  than 
the  soul.     And  yet,  even  created  truth,  which  resides  in  our 
intellect,   is  greater   than  the  soul,   not    simply,   but  in  a 


235  CONCERNING  TRUTH  Q.  i6.  Art.  7 

certain  degree,  in  so  far  as  it  is  its  perfection;  even  as  science 
may  be  said  to  be  greater  than  the  soul.  Yet  it  is  true 
that  nothing  subsisting  is  greater  than  the  rational  soul, 
except  God. 

Reply  Obj.  2.  The  saying  of  Anselm  is  correct  in  so  far 
as  things  are  said  to  be  true  by  their  relation  to  the  divine 
intellect. 

Seventh  Article, 
whether  created  truth  is  eternal  .'* 

We  proceed  thus  to  the  Seventh  Article  : — 

Objection  i.  It  seems  that  created  truth  is  eternal.  Fo; 
Augustine  says  (De  Lib.  Arbit.  ii.  8),  Nothing  is  more  eternal 
than  the  nature  of  a  circle,  and  that  two  added  to  three  make 
five.  But  the  truth  of  these  is  a  created  truth.  Therefore 
created  truth  is  eternal. 

Obj.  2.  Further,  that  which  is  always,  is  eternal.  But 
universals  are  always  and  everywhere;  therefore  they  are 
eternal.     So  therefore  is  truth,  which  is  the  most  universal. 

Obj.  3.  Further,  it  was  always  true  that  what  is  true  in 
the  present  was  to  be  in  the  future.  But  as  the  truth  of  a 
proposition  regarding  the  present  is  a  created  truth,  so  is 
that  of  a  proposition  regarding  the  future.  Therefore  some 
created  truth  is  eternal. 

Obj.  4.  Further,  all  that  is  without  beginning  and  end  is 
eternal.  But  the  truth  of  enunciables  is  without  beginning 
and  end;  for  if  their  truth  had  a  beginning,  since  it  was 
not  before,  it  was  true  that  truth  was  not,  and  true,  of 
course,  by  reason  of  truth;  so  that  truth  was  before  it 
began  to  be.  Similarly,  if  it  be  asserted  that  truth  has  an 
end,  it  follows  that  it  is  after  it  has  ceased  to  be,  for  it 
will  still  be  true  that  truth  is  not.  Therefore  truth  is 
eternal. 

On  the  contrary,  God  alone  is  eternal,  as  laid  down  before 
(Q.  X.,  A.  3). 

I  answer  that,  The  truth  of  enunciations  is  no  other  than 
the  truth  of  the  intellect.  For  an  enunciation  resides  in  the 
intellect,  and  in  speech.     Now  according  as  itj  is  in  the 


Q.  i6.  Art.  7    THE  "  SUMMA  THEOLOGICA  "  236 

intellect  it  has  truth  of  itself:  but  according  as  it  is  in 
speech,  it  is  called  enunciable  truth,  according  as  it 
signifies  some  truth  of  the  intellect,  not  on  account  of 
any  truth  residing  in  the  enunciation,  as  though  in  a 
subject.  Thus  urine  is  called  healthy,  not  from  any 
health  within  it  but  from  the  health  of  an  animal 
which  it  indicates.  In  like  manner  it  has  been  already 
said  that  things  are  called  true  from  the  truth  of  the 
intellect.  Hence,  if  no  intellect  were  eternal,  no  truth 
would  be  eternal.  Now  because  only  the  divine  intellect 
is  eternal,  in  it  alone  truth  has  eternity.  Nor  does  it  follow 
from  this  that  anything  else  but  God  is  eternal;  since  the 
truth  of  the  divine  intellect  is  God  Himself,  as  shown 
already  (A.  5). 

Reply  Obj.  i.  The  nature  of  a  circle,  and  the  fact  that 
two  and  three  make  five,  have  eternity  in  the  mind  of  God. 

Reply  Obj.  2.  That  something  is  always  and  everywhere, 
can  be  understood  in  two  ways.  In  one  way,  as  having 
in  itself  the  power  of  extension  to  all  time  and  to  all  places, 
as  it  belongs  to  God  to  be  everywhere  and  always.  In  the 
other  way  as  not  having  in  itself  determination  to  any  place 
or  time,  as  primary  matter  is  said  to  be  one,  not  because 
it  has  one  form,  as  man  is  one  by  the  unity  of  one  form, 
but  by  the  absence  of  all  distinguishing  form.  In  this 
manner  all  universals  are  said  to  be  everywhere  and  always, 
in  so  far  as  universals  are  independent  of  place  and  time. 
It  does  not,  however,  follow  from  this  that  they  are  eternal, 
except  in  an  intellect,  if  one  exists  that  is  eternal. 

Reply  Obj.  3.  That  which  now  is,  was  future,  before  it 
(actually)  was;  because  it  was  in  its  cause  that  it  would  be. 
Hence,  if  the  cause  were  removed,  that  thing's  coming  to 
be  was  not  future.  But  the  first  cause  is  alone  eternal. 
Hence  it  does  not  follow  that  it  was  always  true  that  what 
now  is  would  be,  except  in  so  far  as  its  future  being  was 
in  the  sempiternal  cause;  and  God  alone  is  such  a  cause. 

Reply  Obj.  4.  Because  our  intellect  is  not  eternal,  neither 
is  the  truth  of  enunciable  propositions  which  are  formed 
by  us,  eternal,  but  it  had  a  beginning  in  time.     Now  before 


237  CONCERNING  TRUTH  Q.  i6.  Art.  8 

such  truth  existed,  it  was  not  true  to  say  that  such  a 
truth  did  exist,  except  by  reason  of  the  divine  intellect, 
wherein  alone  truth  is  eternal.  But  it  is  true  now  to  say 
that  that  truth  did  not  then  exist :  and  this  is  true  only  by 
reason  of  the  truth  that  is  now  in  our  intellect ;  and  not 
by  reason  of  any  truth  in  the  things.  For  this  is  truth 
concerning  not-being;  and  not-being  has  no  truth  of  itself, 
but  only  so  far  as  our  intellect  apprehends  it.  Hence  it  is 
true  to  say  that  truth  did  not  exist,  in  so  far  as  we  appre- 
hend its  not-being  as  preceding  its  being. 

Eighth  Article, 
whether  truth  is  immutable  ? 

We  proceed  thus  to  the  Eighth  Article  : — 

Objection  i.  It  seems  that  truth  is  immutable.  For 
Augustine  says  [De  Lib.  Arbit.  ii.  12),  that  Truth  and 
mind  do  not  rank  as  equals,  otherwise  truth  would  be  mutable, 
as  the  mind  is. 

Obj.  2.  Further,  what  remains  after  every  change  is 
immutable;  as  primary  matter  is  unbegotten  and  incor- 
ruptible, since  it  remains  after  all  generation  and  corruption. 
But  truth  remains  after  all  change;  for  after  every  change 
it  is  true  to  say  that  a  thing  is,  or  is  not.  Therefore,  truth 
is  immutable. 

Obj.  3.  Further,  if  the  truth  of  an  enunciation  changes,  it 
changes  mostly  with  the  changing  of  the  thing.  But  it 
does  not  thus  change.  For  truth,  according  to  Anselm 
[De  Verit.  viii.),  is  a  certain  rightness  in  so  far  as  a  thing 
answers  to  that  which  is  in  the  divine  mind  concerning  it. 
But  this  proposition  Socrates  sits,  receives  from  the  divine 
mind  the  signification  that  Socrates  does  sit;  and  it  has  the 
same  signification  even  though  he  does  not  sit.  Therefore 
the  truth  of  the  proposition  in  no  way  changes. 

Obj.  4.  Further,  where  there  is  the  same  cause,  there  is 
the  same  effect.  But  the  same  thing  is  the  cause  of  the 
truth  of  the  three  propositions,  Socrates  sits,  will  sit,  sat. 
Therefore  the  truth  of  each  is  the  same.    But  one  or  other 


Q.  16.  Art.  8    THE  "  SUMMA  THEOLOGICA  "  238 

of  these  must  be  the  true  one.  Therefore  the  truth  of  these 
propositions  remains  immutable;  and  for  the  same  reason 
that  of  any  other. 

On  the  contrary,  It  is  written  (Ps.  xi.  2),  Truths  are  decayed 
from  among  the  children  of  men. 

I  answer  that,  Truth,  properly  speaking,  resides  only  in 
the  intellect,  as  said  before  (A.  i) ;  but  things  are  called  true 
in  virtue  of  the  truth  residing  in  an  intellect.  Hence  the 
mutability  of  truth  must  be  regarded  from  the  point  of  view 
of  the  intellect,  the  truth  of  which  consists  in  its  conformity 
to  the  thing  understood.  Now  this  conformity  may  vary 
in  two  ways,  even  as  any  other  likeness,  through  change  in 
one  of  the  two  extremes.  Hence  in  one  way  truth  varies 
on  the  part  of  the  intellect,  from  the  fact  that  a  change  of 
opinion  occurs  about  a  thing  which  in  itself  has  not  changed, 
and  in  another  way,  when  the  thing  is  changed,  but  not 
the  opinion;  and  in  either  way  there  can  be  a  change  from 
true  to  false.  If,  then,  there  is  an  intellect  wherein  there 
can  be  no  alternation  of  opinions,  and  the  knowledge  of 
which  nothing  can  escape,  in  this  is  immutable  truth.  Now 
such  is  the  divine  intellect,  as  is  clear  from  what  has  been 
said  before  (Q.  XIV.,  A.  15).  Hence  the  truth  of  the 
divine  intellect  is  immutable.  But  the  truth  of  our  intellect 
is  mutable;  not  because  it  is  itself  the  subject  of  change, 
but  in  so  far  as  our  intellect  changes  from  truth  to  falsity, 
for  thus  forms  may  be  called  mutable.  Whereas  the  truth 
of  the  divine  intellect  is  that  according  to  which  natural 
things  are  said  to  be  true,  and  this  is  altogether  immutable. 

Reply  Obj.  i.  Augustine  is  speaking  of  divine  truth. 

Reply  Obj.  2.  The  true  and  being  are  convertible  terms. 
Hence  just  as  being  is  not  generated  nor  corrupted  of  itself, 
but  accidentally,  in  so  far  as  this  being  or  that  is  corrupted 
or  generated,  as  is  said  in  Physic,  i.,  so  does  truth  change, 
not  so  as  that  no  truth  remains,  but  because  that  truth 
does  not  remain  which  was  before. 

Reply  Obj.  3.  A  proposition  not  only  has  truth,  as  other 
things  are  said  to  have  it,  in  so  far,  that  is,  as  they  corre- 
spond to  that  which  is  the  design  of  the  divine  intellect 


239  CONCERNING  TRUTH         Q.  i6.  Art.  8 

concerning  them;  but  it  is  said  to  have  truth  in  a  special 
way,  in  so  far  as  it  indicates  the  truth  of  the  intellect,  which 
consists  in  the  conformity  of  the  intellect  with  a  thing. 
When  this  disappears,  the  truth  of  an  opinion  changes,  and 
consequently  the  truth  of  the  proposition.  So  therefore 
this  proposition,  Socrates  sits,  is  true,  as  long  as  he  is  sitting, 
both  with  the  truth  of  the  thing,  in  so  far  as  the  expression 
is  significative,  and  with  the  truth  of  signification,  in  so  far 
as  it  signifies  a  true  opinion.  When  Socrates  rises,  the  first 
truth  remains,  but  the  second  is  changed. 

Reply  Obj.  4.  The  sitting  of  Socrates,  which  is  the  cause 
of  the  truth  of  the  proposition,  Socrates  sits,  has  not  the 
same  meaning  when  Socrates  sits,  after  he  sits,  and  before 
he  sits.  Hence  the  truth  which  results,  varies,  and  is 
variously  sig  ij&ed  by  these  propositions  concerning  present, 
past,  or  future.  Thus  it  does  not  follow,  though  one  of 
the  three  propositions  is  true,  that  the  same  truth  remains 
invariable. 


QUESTION  XVII. 

CONCERNING  FALSITY. 

{In  Four  Articles.) 

We  next  consider  falsity.  About  this  four  points  of 
inquiry  arise  :  (i)  Whether  falsity  exists  in  things  ? 
(2)  Whether  it  exists  in  the  sense  ?  (3)  Whether  it  exists 
in  the  ntiellect  ?  (4)  Concerning  the  opposition  of  the  true 
and  the  false. 

First  Article, 
whether  falsity  exists  in  things  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  appears  that  falsity  does  not  exist  in 
things.  For  Augustine  says  (Soliloq.  ii.  8),  If  the  true  is  that 
which  is,  it  will  he  concluded  that  the  false  exists  nowhere  ; 
whatever  reason  may  appear  to  the  contrary. 

Ohj.  2.  Further,  false  is  derived  iiom  falter e  (to  deceive). 
But  things  do  not  deceive;  for,  as  Augustine  says  {De  vera 
y^lig'  33),  they  show  nothing  but  their  own  species.  There- 
fore the  false  is  not  found  in  things. 

Ohj.  3.  Further,  the  true  is  said  to  exist  in  things  by  con- 
formity  to  the  divine  intellect,  as  stated  above  (Q.  XVI.). 
But  everything,  in  so  far  as  it  exists,  imitates  God.  There- 
fore everything  is  true  without  admixture  of  falsity ;  and 
thus  nothing  is  false. 

On  the  contrary,  Augustine  says  {ihid.  34) :  Every  hody  is  a 
true  hody  and  a  false  unity  :  for  ii  imitates  unity  without  being 
unity.  But  everything  imitates  the  divine  unity  yet  falls 
short  of  it.     Therefore  in  all  things  falsity  exists. 

/  answer  that,  Since  true  and  false  are  opposed,  and  since 
opposites  stand  in  relation  to  the  same  thing,  we  must 

240 


241  CONCERNING  FALSITY         Q.  17.  Art.  i 

needs  seek  falsity,  where  primarily  we  find  truth ;  that  is  to 
say,  in  the  intellect.  Now,  in  things,  neither  truth  nor 
falsity  exists,  except  in  relation  to  the  intellect.  And  since 
every  thing  is  denominated  simply  by  what  belongs  to  it 
per  se,  but  is  denominated  relatively  by  what  belongs  to 
it  accidentally ;  a  thing  indeed  may  be  called  false  simply 
when  compared  with  the  intellect  on  which  it  depends, 
and  to  which  it  is  compared  per  se  ;  but  may  be  called 
false  relatively  as  directed  to  another  intellect,  to  which 
it  is  compared  accidentally.  Now  natural  things  depend 
on  the  divine  intellect,  as  artificial  things  on  the  human. 
Wherefore  artificial  things  are  said  to  be  false  simply  and 
in  themselves,  in  so  far  as  they  fall  short  of  the  form  of  the 
art;  whence  a  craftsman  is  said  to  produce  a  false  work, 
if  it  falls  short  of  the  proper  operation  of  his  art. 

In  things  that  depend  on  God,  falseness  cannot  be  found, 
in  so  far  as  they  are  compared  with  the  divine  intellect; 
since  whatever  takes  place  in  things  proceeds  from  the 
ordinance  of  that  intellect,  unless  perhaps  in  the  case  of 
voluntary  agents  only,  who  have  it  in  their  power  to  with- 
draw themselves  from  what  is  so  ordained ;  wherein  consists 
the  evil  of  sin.  Thus  sins  themselves  are  called  untruths 
and  lies  in  the  Scriptures,  according  to  the  words  of  the  text. 
Why  do  you  love  vanity,  and  seek  after  lying  ?  (Ps.  iv.  3) :  as 
on  the  other  hand  virtuous  deeds  are  called  the  truth  of  life 
as  being  obedient  to  the  order  of  the  divine  intellect.  Thus 
it  is  said,  He  that  doth  truth,  cometh  to  the  light  (John  iii.  21). 

But  in  relation  to  our  intellect,  natural  things  which  are 
compared  thereto  accidentally,  can  be  called  false;  not 
simply,  but  relatively;  and  that  in  two  ways.  In  one  way 
according  to  the  thing  signified,  and  thus  a  thing  is  said  to  be 
false  as  being  signified  or  represented  by  word  or  thought 
that  is  false.  In  this  respect  anything  can  be  said  to  be  false 
as  regards  any  quality  not  possessed  by  it;  as  if  we  should 
say  that  a  diameter  is  a  false  commensurable  thing,  as  the 
Philosopher  says  (Metaph.  v.  34).  So,  too,  Augustine  says 
(Soliloq.  ii.  10) :  The  true  tragedian  is  a  false  Hector:  even  as, 
on  the  contrary,  anything  can  be  called  true,  in  regard  to 
I,  16 


Q.  17.  Art.  i    THE  "  SUMMA  THEOLOGICA  "  242 

that  which  is  becoming  to  it.  In  another  way  a  thing  can 
be  called  false,  by  way  of  cause — and  thus  a  thing  is  said  to 
be  false  that  naturally  begets  a  false  opinion.  And  whereas 
it  is  innate  in  us  to  judge  of  things  by  external  appearances, 
since  our  knowledge  takes  its  rise  from  sense,  which  principally 
and  naturally  deals  with  external  accidents,  therefore  those 
external  accidents,  which  resemble  things  other  than  them- 
selves, are  said  to  be  false  with  respect  to  those  things; 
thus  gall  is  falsely  honey;  and  tin,  false  gold.  Regarding 
this,  Augustine  says  {ibid.  6) :  We  call  those  things  false  that 
appear  to  our  apprehension  like  the  true:  and  the  Philosopher 
says  [loc.  cit.):  Things  are  called  false  that  are  naturally  apt 
to  appear  such  as  they  are  not,  or  what  they  are  not.  In  this 
way  a  man  is  called  false  as  delighting  in  false  opinions  or 
words,  and  not  because  he  can  invent  them ;  for  in  this  way 
many  wise  and  learned  persons  might  be  called  false,  as 
stated  in  Metaph.  v.  34. 

Reply  Ohj.  i.  A  thing  compared  with  the  intellect  is 
said  to  be  true  in  respect  to  what  it  is;  and  false  in  respect 
to  what  it  is  not.  Hence,  The  true  tragedian  is  a  false  Hector, 
as  stated  in  Soliloq.  ii.  {loc.  cit.).  As,  therefore,  in  things 
that  are  is  found  a  certain  non-being,  so  in  things  that 
are  is  found  a  degree  of  falseness. 

Reply  Ohj.  2.  Things  do  not  deceive  by  their  own  nature, 
but  by  accident.  For  they  give  occasion  to  falsity,  by  the 
likeness  they  bear  to  things  which  they  actually  are  not. 

Reply  Ohj.  3.  Things  are  said  to  be  false,  not  as  compared 
with  the  divine  intellect,  in  which  case  they  would  be 
false  simply,  but  as  compared  with  our  intellect;  and 
thus  they  are  false  only  relatively. 

To  the  argument  which  is  urged  on  the  contrary,  like- 
ness or  defective  representation  does  not  involve  the  idea 
of  falsity  except  in  so  far  as  it  gives  occasion  to  false  opinion. 
Hence  a  thing  is  not  always  said  to  be  false,  because  it 
resembles  another  thing;  but  only  when  the  resemblance 
is  such  as  naturally  to  produce  a  false  opinion,  not  in  any  one 
case,  but  in  the  majority  of  instances. 


243  CONCERNING  FALSITY        Q.  17.  Art.  2 

Second  Article, 
whether  there  is  falsity  in  the  senses  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  falsity  is  not  in  the  senses. 
For  Augustine  says  {De  vera  relig.  33) :  //  all  the  bodily  senses 
report  as  they  are  affected,  I  do  not  know  what  more  we  can 
require  from  them.  Thus  it  seems  that  we  are  not  deceived 
by  the  senses ;  and  therefore  that  falsity  is  not  in  them. 

Obj.  2.  Further,  the  Philosopher  says  (Metaph.  iv.  24)  that 
falsity  is  not  proper  to  the  senses,  but  to  the  imagination. 

Obj.  3.  Further,  in  non-complex  things  there  is  neither 
true  nor  false,  but  in  complex  things  only.  But  affirmation 
and  negation  do  not  belong  to  the  senses.  Therefore  in  the 
senses  there  is  no  falsity. 

On  the  contrary,  Augustine  says  (Soliloq.  ii.  6),  It  appears 
that  the  senses  entrap  us  into  error  by  their  deceptive  similitudes. 

I  answer  that,  Falsity  is  not  to  be  sought  in  the  senses 
except  as  truth  is  in  them.  Now  truth  is  not  in  them  in 
such  a  way  as  that  the  senses  know  truth,  but  in  so  far  as 
they  apprehend  sensible  things  truly,  as  said  above  (Q.  XVL, 
A.  2),  and  this  takes  place  through  the  senses  apprehending 
things  as  they  are,  and  hence  it  happens  that  falsity  exists 
in  the  senses  through  their  apprehending  or  judging  things 
to  be  otherwise  than  they  reaUy  are. 

The  knowledge  of  things  by  the  senses  is  in  proportion  to 
the  existence  of  their  Hkeness  in  the  senses;  and  the  like- 
ness of  a  thing  can  exist  in  the  senses  in  three  ways.  In  the 
first  way,  primarily  and  of  its  own  nature,  as  in  sight  there 
is  the  likeness  of  colours,  and  of  other  sensible  objects  proper 
to  it.  Secondly,  of  its  own  nature,  though  not  primarily; 
as  in  sight  there  is  the  likeness  of  shape,  size,  and  of  other 
sensible  objects  common  to  more  than  one  sense.  Thirdly, 
neither  primarily  nor  of  its  own  nature,  but  accidentally,  as 
in  sight,  there  is  the  likeness  of  a  man,  not  as  man,  but  in  so 
far  as  it  is  accidental  to  the  coloured  object  to  be  a  man. 
Sense,  then,  has  no  false  knowledge  about  its  proper 
objects,  except  accidentally  and  rarely,  and  then^  because  of 


Q.  17.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  244 

the  unsound  organ  it  does  not  receive  the  sensible  form 
rightly;  just  as  other  passive  subjects  because  of  their  indis- 
position receive  defectively  the  impressions  of  the  agent. 
Hence,  for  instance,  it  happens  that  on  account  of  an  un- 
healthy tongue  sweet  seems  bitter  to  a  sick  person.  But  as 
to  common  objects  of  sense,  and  accidental  objects,  even  a 
rightly  disposed  sense  may  have  a  false  judgment,  because 
it  is  referred  to  them  not  directly,  but  accidentally,  or  as  a 
consequence  of  being  directed  to  other  things. 

Reply  Obj.  i.  The  affection  of  sense  is  its  sensation  itself. 
Hence,  from  the  fact  that  sense  reports  as  it  is  affected,  it 
follows  that  we  are  not  deceived  in  the  judgment  by  which 
we  judge  that  we  experience  sensation.  Since,  however, 
sense  is  sometimes  affected  erroneously  by  its  object,  it  follows 
that  it  sometimes  reports  erroneously  of  that  object;  and 
thus  we  are  deceived  by  sense  about  the  object,  but  not  about 
the  fact  of  sensation. 

Reply  Obj.  2.  Falsity  is  said  not  to  be  proper  to  sense, 
since  sense  is  not  deceived  as  to  its  proper  object.  Hence 
in  another  translation  it  is  said  more  plainly.  Sense,  about 
its  proper  object,  is  never  false.  Falsity  is  attributed  to 
the  imagination,  as  it  represents  the  likeness  of  some- 
thing even  in  its  absence.  Hence,  when  anyone  perceives 
the  likeness  of  a  thing  as  if  it  were  the  thing  itself,  falsity 
results  from  such  an  apprehension;  and  for  this  reason 
the  Philosopher  (Metaph.  v.  34)  says  that  shadows,  pictures, 
and  dreams  are  said  to  be  false  inasmuch  as  they  convey  the 
likeness  of  things  that  are  not  present  in  substance. 

Rtpiy  Obj.  3.  This  argument  proves  that  the  false  is  not 
in  the  sense,  as  in  that  which  knows  the  true  and  the  false. 

Third  Article, 
whether  falsity  is  in  the  intellect  ? 

We  proceed  thus  to  the  Third  Article : — 

Objection  i.  It  seems  that  falsity  is  not  in  the  intellect. 
For  Augustine  says  (Qq.  Ixxxiii.  32),  Everyone  who  is  deceived, 
understands  not  that  in  which  he  is  deceived.     But  falsity 


245  CONCERNING   FALSITY         Q.  17.  Art.  3 

is  said  to  exist  in  any  knowledge  in  so  far  as  we  are  deceived 
therein.     Therefore  falsity  does  not  exist  in  the  intellect. 

Ohj.  2.  Further,  the  Philosopher  says  (De  anima  iii.  51) 
that  the  intellect  is  always  right.  Therefore  there  is  no 
falsity  in  the  intellect. 

On  the  contrary,  It  is  said  in  De  anima  iii.  21,  22  that 
where  there  is  composition  of  objects  understood,  there  is  truth 
and  falsehood.  But  such  composition  is  in  the  intellect. 
Therefore  truth  and  falsehood  exist  in  the  intellect. 

/  answer  that,  Just  as  a  thing  has  being  by  its  proper  form, 
so  the  knowing  faculty  has  knowledge  by  the  likeness  of  the 
thing  known.  Hence,  as  natural  things  cannot  fall  short  of 
the  being  that  belongs  to  them  by  their  form,  but  may  fall 
short  of  accidental  or  consequent  qualities,  even  as  a  man 
may  fail  to  possess  two  feet,  but  not  fail  to  be  a  man ;  so  the 
faculty  of  knowing  cannot  fail  in  knowledge  of  the  thing 
with  the  likeness  of  which  it  is  informed ;  but  may  fail  with 
regard  to  something  consequent  upon  that  form,  or  acci- 
dental thereto.  For  it  has  been  said  (A.  2),  that  sight  is  not 
deceived  in  its  proper  sensible,  but  about  common  sensibles 
that  are  consequent  to  that  object;  or  about  accidental 
objects  of  sense.  Now  as  the  sense  is  directly  informed  by 
the  likeness  of  its  proper  object,  so  is  the  intellect  by  the 
Hkeness  of  the  essence  of  a  thing.  Hence  the  intellect  is 
not  deceived  about  the  essence  of  a  thing,  as  neither  the 
sense  about  its  proper  object.  But  in  affirming  and  deny- 
ing, the  intellect  may  be  deceived,  by  attributing  to  the 
thing  of  which  it  understands  the  essence,  something  which 
is  not  consequent  upon  it,  or  is  opposed  to  it.  For  the 
intellect  is  in  the  same  position  as  regards  judging  of  such 
things,  as  sense  is  as  to  judging  of  common,  or  accidental, 
sensible  objects.  There  is,  however,  this  difference,  as 
before  mentioned  regarding  truth  (Q.  XVL,  A.  2),  that 
falsity  can  exist  in  the  intellect  not  only  because  the  know- 
ledge of  the  intellect  is  false,  but  because  the  Intellect  is 
conscious  of  that  knowledge,  as  it  is  conscious  of  truth; 
whereas  in  sense  falsity  does  not  exist  as  known,  as  stated 
above  (A.  2). 


Q.  17.  Art.  4    THE  "  SUMMA  THEOLOGICA  '*  246 

But  because  falsity  of  the  intellect  is  concerned  essenti- 
ally only  with  the  composition  of  the  intellect,  falsity  occurs 
also  accidentally  in  that  operation  of  the  intellect  whereby  it 
knows  the  essence  of  a  thing,  in  so  far  as  composition  of  the 
intellect  is  mixed  up  in  it.  This  can  take  place  in  two  ways. 
In  one  way,  by  the  intellect  applying  to  one  thing  the 
definition  proper  to  another;  as  that  of  a  circle  to  a  man. 
Wherefore  the  definition  of  one  thing  is  false  of  another. 
In  another  way,  by  composing  a  definition  of  parts  which 
are  mutually  exclusive.  For  thus  the  definition  is  not  only 
false  of  the  thing,  but  false  in  itself.  A  definition  such  as 
'  a  reasonable  four-footed  animal '  would  be  of  this  kind, 
and  the  intellect  false  in  making  it;  for  such  a  statement 
as  '  some  reasonable  animals  are  four-footed  '  is  false  in 
itself.  For  this  reason  the  intellect  cannot  be  false  in  its 
knowledge  of  simple  essences;  but  it  is  either  true,  or  it 
understands  nothing  at  all. 

Reply  Ohj.  i.  Because  the  essence  of  a  thing  is  the  proper 
object  of  the  intellect,  we  are  properly  said  to  understand  a 
thing  when  we  reduce  it  to  its  essence,  and  judge  of  it 
thereby;  as  takes  place  in  demonstrations,  in  which  there  is 
no  falsity.  In  this  sense  Augustine's  words  must  be  under- 
stood, that  he  who  is  deceived,  understands  not  that  wherein 
he  is  deceived;  and  not  in  the  sense  that  no  one  is  ever  de- 
ceived in  any  operation  of  the  intellect. 

Reply  Ohj.  2.  The  intellect  is  always  right  as  regards  first 
principles;  since  it  is  not  deceived  about  them  for  the  same 
reason  that  it  is  not  deceived  about  what  a  thing  is.  For 
self-known  principles  are  such  as  are  known  as  soon  as 
the  terms  are  understood,  from  the  fact  that  the  predicate 
is  contained  in  the  definition  of  the  subject. 


Fourth  Article, 
whether  true  and  false  are  contraries  ? 

We  proceed  thus  to  the  Fourth  Article : — 
Objection  i.  It  seems  that  true  and  false  are  not  con- 
traries.    For  true  and  false  are  opposed,  as  that  which  is  to 


247  CONCERNING  FALSITY         Q.  17.  Art.  4 

that  which  is  not;  for  truth,  as  Augustine  says  (Soliloq.  ii.  5), 
is  that  which  is.  But  that  which  is  and  that  which  is  not  are 
not  opposed  as  contraries.  Therefore  true  and  false  are 
not  contrary  things. 

Obj.  2.  Further,  one  of  two  contraries  is  not  in  the 
other.  But  falsity  is  in  truth,  because,  as  Augustine  says, 
(Soliloq.  ii.  10),  A  tragedian  would  not  be  a  false  Hector,  if  he 
were  not  a  true  tragedian.  Therefore  true  and  false  are  not 
contraries, 

Obj.  3.  Further,  in  God  there  is  no  contrariety,  for  nothing 
is  contrary  to  the  Divine  Substance,  as  Augustine  says  (De  civ. 
Dei,  xii.  2).  But  falsity  is  opposed  to  God,  for  an  idol  is 
called  in  Scripture  a  lie,  They  have  laid  hold  on  lying  (Jer. 
viii.  5),  that  is  to  say,  an  idol,  as  a  gloss  says.  Therefore 
false  and  true  are  not  contraries. 

On  the  contrary.  The  Philosopher  says  (Periherm.  ii.),  that 
a  false  opinion  is  contrary  to  a  true  one. 

I  answer  that.  True  and  false  are  opposed  as  contraries, 
and  not,  as  some  have  said,  as  affirmation  and  negation. 
In  proof  of  which  it  must  be  considered  that  negation  neither 
asserts  anything  nor  determines  any  subject,  and  can  there- 
fore be  said  of  being  as  of  not-being,  for  instance  not-seeing 
or  not-sitting.  But  privation  asserts  nothing,  whereas  it 
determines  its  subject,  for  it  is  negation  in  a  subject,  as  stated 
in  Metaph.  iv.  4:  v.  27;  for  blindness  is  not  said  except  of 
one  whose  nature  it  is  to  see.  Contraries,  however,  both 
assert  something  and  determine  the  subject,  for  blackness 
is  a  species  of  colour.  Falsity  asserts  something,  for  a  thing 
is  false,  as  the  Philosopher  says  [Metaph.  iv.  27),  inasmuch 
as  something  is  said  or  seems  to  be  something  that  it  is  not, 
or  not  to  be  what  it  really  is.  For  as  truth  impHes  an 
adequate  apprehension  of  a  thing,  so  falsity  impHes  the 
contrary.     Hence  it  is  clear  that  true  and  false  are  contraries. 

Reply  Obj.  i.  What  is  in  things  is  the  truth  of  the  thing; 
but  what  is  apprehended,  is  the  truth  of  the  intellect, 
wherein  truth  primarily  resides.  Hence  the  false  is  that 
which  is  not  as  apprehended.  To  apprehend  being,  and  not- 
being,  implies  contrariety;  for,  as  the  Philosopher  proves, 


Q.  17.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  248 

(Periherm.  ii.),  the  contrary  of  this  statement  good  is  good 
is,  good  is  not  good. 

Reply  Ohj.  2.  Falsity  is  not  founded  in  the  truth  which 
is  contrary  to  it,  just  as  evil  is  not  founded  in  the  good  which 
is  contrary  to  it,  but  in  that  which  is  its  proper  subject.  This 
happens  in  either,  because  true  and  good  are  universals, 
and  convertible  with  being.  Hence,  as  every  privation  is 
founded  in  a  subject,  that  is  a  being,  so  every  evil  is  founded 
in  some  good,  and  every  falsity  in  some  truth. 

Reply  Ohj.  3.  Because  contraries,  and  opposites  by  way  of 
privation,  are  by  nature  about  one  and  the  same  thing, 
therefore  there  is  nothing  contrary  to  God,  considered  in 
Himself,  either  with  respect  to  His  goodness  or  His  truth, 
for  in  His  intellect  there  can  be  nothing  false.  But  in  our 
apprehension  of  Him  contraries  exist,  for  the  false  opinion 
concerning  Him  is  contrary  to  the  true.  So  idols  are  called 
lies,  opposed  to  the  divine  truth,  inasmuch  as  the  false 
opinion  concerning  them  is  contrary  to  the  true  opinion  of 
the  divine  unity. 


QUESTION  XVIII. 

THE   LIFE    OF   GOD. 

{In  Four  Articles.) 

Since  to  understand  belongs  to  living  beings,  after  con- 
sidering the  divine  knowledge  and  intellect,  we  must 
consider  the  divine  life.  About  this,  four  points  of  inquiry 
arise:  (i)  To  whom  does  it  belong  to  live  ?  (2)  What  is 
life  ?  (3)  Whether  life  is  properly  attributed  to  God  ? 
(4)  Whether  all  things  in  God  are  life  ? 

First  Article, 
whether  to  live  belongs  to  all  natural  things  ? 

We  proceed  thus  to  the  First  Article: — 

Objection  1.  It  seems  that  to  Hve  belongs  to  all  natural 
things.  For  the  Philosopher  says  (Phys.  viii.  i)  that  Move- 
ment is  like  a  kind  of  life  possessed  by  all  things  existing  in 
nature.  But  all  natural  things  participate  in  movement. 
Therefore  all  natural  things  partake  in  life. 

Obj.  2.  Further,  plants  are  said  to  live,  inasmuch  as  they 
have  in  themselves  a  principle  of  movement  of  growth  and 
decay.  But  local  movement  is  naturally  more  perfect  than, 
and  prior  to,  movement  of  growth  and  decay,  as  the  Philo- 
sopher shows  {ibid.,  56,  57).  Since,  then,  all  natural  bodies 
have  in  themselves  some  principle  of  local  movement,  it 
seems  that  all  natural  bodies  live. 

Obj.  3.  Further,  amongst  natural  bodies  the  elements  are 
the  less  perfect.  Yet  life  is  attributed  to  them,  for  we 
speak  of  '  living  waters.'  Much  more,  therefore,  have  other 
natural  bodies  life. 

On  the  contrary,  Dionysius  says  (Div»  Nom.  vi.  i)  that 

249 


Q.  i8.  Art.  i     THE  "  SUMMA  THEOLOGICA  "  250 

The  last  echo  of  life  is  heard  in  the  plants,  whereby  it  is  inferred 
that  their  hfe  is  life  in  its  lowest  degree.  But  inanimate 
bodies  are  inferior  to  plants.     Therefore  they  have  not  life. 

/  answer  that,  We  can  gather  to  what  things  life  belongs, 
and  to  what  it  does  not,  from  such  things  as  manifestly 
possess  life.  Now  life  manifestly  belongs  to  animals,  for  it  is 
said  in  De  Vegetab.  i.*  that  in  animals  life  is  manifest.  We 
must,  therefore,  distinguish  living  from  lifeless  things,  by 
comparing  them  to  that  by  reason  of  which  animals  are 
said  to  live:  and  this  it  is  in  which  life  is  manifested  first 
and  remains  last.  We  say  then  that  an  animal  begins  to  live 
when  it  begins  to  move  of  itself :  and  as  long  as  such  move- 
ment appears  in  it,  so  long  is  it  considered  to  be  alive. 
When  it  no  longer  has  any  movement  of  itself,  but  is  only 
moved  by  another  power,  then  its  life  is  said  to  fail,  and  the 
animal  to  be  dead.  Whereby  it  is  clear  that  those  things  are 
properly  called  living  that  move  themselves  by  some  kind 
of  movement,  whether  it  be  movement  properly  so  called, 
as  the  act  of  an  imperfect  thing,  i.e.,  of  a  thing  in  potentiality, 
is  called  movement ;  or  movement  in  a  more  general  sense,  as 
when  said  of  the  act  of  a  perfect  thing,  as  understanding  and 
feeling  are  called  movement.  Accordingly  all  things  are 
said  to  be  alive  that  determine  themselves  to  movement  or 
operation  of  any  kind:  whereas  those  things  that  cannot 
by  their  nature  do  so,  cannot  be  called  living,  unless  by 
a  similitude. 

Reply  Ohj.  i.  These  words  of  the  Philosopher  may  be 
understood  either  of  the  first  movement,  namely,  that  of  the 
celestial  bodies,  or  of  movement  in  its  general  sense.  In 
either  way  is  movement  called  the  life,  as  it  were,  of  natural 
bodies,  speaking  by  a  similitude,  and  not  attributing  it  to 
them  as  their  property.  The  movement  of  the  heavens  is 
in  the  universe  of  corporeal  natures  as  the  movement  of  the 
heart,  whereby  life  is  preserved,  is  in  animals.  Similarly 
also  every  natural  movement  in  respect  to  natural  things 
has  a  certain  similitude  to  the  operations  of  life.  Hence, 
if  the  whole  corporeal  imiverse  were  one  animal,  so  that  its 

*  De  Plantis  i.  i. 


351  THE  LIFE  OF  GOD  Q.i8.Art.2 

movement  came  from  an  intrinsic  moving  force,  as  some  in 
fact  have  held,  in  that  case  movement  would  really  be  the 
life  of  all  natural  bodies. 

Reply  Ohj.  3.  To  bodies,  whether  heavy  or  light,  move- 
ment does  not  belong,  except  in  so  far  as  they  are  displaced 
from  their  natural  conditions,  and  are  out  of  their  proper 
place;  for  when  they  are  in  the  place  that  is  proper  and 
natural  to  them,  then  they  are  at  rest.  Plants  and  other 
living  things  move  with  vital  movement,  in  accordance  with 
the  disposition  of  their  nature,  but  not  by  approaching 
thereto,  or  by  receding  from  it,  for  in  so  far  as  they  recede 
from  such  movement,  so  far  do  they  recede  from  their 
natural  disposition.  Heavy  and  light  bodies  are  moved  by 
an  extrinsic  force,  either  generating  them  and  giving  them 
form,  or  removing  obstacles  from  their  way.  They  do  not 
therefore  move  themselves,  as  do  living  bodies. 

Reply  Ohj.  3.  Waters  are  called  living  that  have  a  con- 
tinuous current :  for  standing  waters,  that  are  not  connected 
with  a  continually  flowing  source,  are  called  dead,  as  in 
cisterns  and  ponds.  This  is  merely  a  similitude,  inasmuch 
as  the  movement  they  are  seen  to  possess  makes  them  look  as 
if  they  were  alive.  Yet  this  is  not  life  in  them  in  its  real 
sense,  since  this  movement  of  theirs  is  not  from  themselves 
but  from  the  cause  that  generates  them.  The  same  is  the 
case  with  the  movement  of  other  heavy  and  light  bodies. 

Second  Article, 
whether  life  is  an  operation  ? 

We  proceed  thus  to  the  Second  Article : — 

Objection  i.  It  seems  that  life  is  an  operation.  For 
nothing  is  divided  except  into  parts  of  the  same  genus.  But 
life  is  divided  by  certain  operations,  as  is  clear  from  the 
Philosopher  [De  anima  ii.  13),  who  distinguishes  four  kinds 
of  life,  namely  nourishment,  sensation,  local  movement,  and 
understanding.     Therefore  life  is  an  operation. 

Ohj,  2,  Further,  the  active  life  is  said  to  be  different 
from  the  contemplative.     But  the  contemplative  is  only 


Q.  i8.  Art.  2    THE  *'  SUMMA  THEOLOGICA  "  252 

distinguished  from  the  active  by  certain  operations.     There- 
fore life  is  an  operation. 

Ohj.  3.  Further,  to  know  God  is  an  operation.  But  this 
is  Hfe,  as  is  clear  from  the  words  of  John  xviii.  3,  Now  this  is 
eternal  life,  that  they  may  know  Thee,  the  only  true  God. 
Therefore  life  is  an  operation. 

On  the  contrary,  The  Philosopher  says  {De  aniina  ii.  37), 
In  living  things  to  live  is  to  he. 

I  answer  that,  As  is  clear  from  what  has  been  said  (Q.  XVII., 
A.  3),  our  intellect,  which  takes  cognizance  of  the  essence  of  a 
thing  as  its  proper  object,  gains  knowledge  from  sense,  of 
which  the  proper  obj  ects  are  external  accidents.  Hence  from 
external  appearances  we  come  to  the  knowledge  of  the 
essence  of  things.  And  because  we  name  a  thing  in  accor- 
dance with  our  knowledge  of  it,  as  is  clear  from  what  has 
already  been  said  (Q.  XIII.  A.  i),  so  from  external  properties 
names  are  often  imposed  to  signify  essences.  Hence  such 
names  are  sometimes  taken  strictly  to  denote  the  essence 
itself,  the  signification  of  which  is  their  principal  object ;  but 
sometimes,  and  less  strictly,  to  denote  the  properties  by 
reason  of  which  they  are  imposed.  And  so  we  see  that  the 
word  body  is  used  to  denote  a  genus  of  substances  from  the 
fact  of  their  possessing  three  dimensions:  and  is  sometimes 
taken  to  denote  the  dimensions  themselves;  in  which  sense 
body  is  said  to  be  a  species  of  quantity.  The  same  must 
be  said  of  life.  The  name  is  given  from  a  certain  external 
appearance,  namely,  self -movement,  yet  not  precisely  to 
signify  this,  but  rather  a  substance  to  which  self-movement 
and  the  application  of  itself  to  any  kind  of  operation,  belong 
naturally.  To  live,  accordingly,  is  nothing  else  than  to 
exist  in  this  or  that  nature ;  and  life  signifies  this,  though  in 
the  abstract,  just  as  the  word  running  denotes  to  run  in  the 
abstract. 

Hence  living  is  not  an  accidental  but  an  essential  predicate. 
Sometimes,  however,  life  is  used  less  properly  for  the 
operations  from  which  its  name  is  taken,  and  thus  the 
Philosopher  says  [Ethic,  ix.  9)  that  to  live  is  principally  to 
sense  or  to  understand. 


253  THE  LIFE  OF  GOD  Q.iS.Art.s 

Reply  Ohj.  i.  The  Philosopher  here  takes  to  live  to  mean 
an  operation  of  Hfe.  Or  it  would  be  better  to  say  that 
sensation  and  intelligence,  and  the  like,  are  sometimes  taken 
for  the  operations,  sometimes  for  the  existence  itself  of  the 
operator.  For  he  says  [Ethic,  ix.  9)  that  to  live  is  to  sense  or 
to  understand — in  other  words,  to  have  a  nature  capable  oi 
sensation  or  understanding.  Thus,  then,  he  distinguishes  Hfe 
by  the  four  operations  mentioned.  For  in  this  lower  world 
there  are  four  kinds  of  living  things.  It  is  the  nature  of 
some  to  be  capable  of  nothing  more  than  taking  nourishment, 
and,  as  a  consequence,  of  growing  and  generating.  Others 
are  able,  in  addition,  to  sense,  as  we  see  in  the  case  of  shellfish 
and  other  animals  without  movement.  Others  have  the 
further  power  of  moving  from  place  to  place,  as  perfect 
animals,  such  as  quadrupeds,  and  birds,  and  so  on.  Others, 
as  man,  have  the  still  higher  faculty  of  understanding. 

Reply  Ohj.  2.  By  vital  operations  are  meant  those  whose 
principles  are  within  the  operator,  and  in  virtue  of  which 
the  operator  produces  such  operations  of  itself.  It  happens 
that  there  exist  in  men  not  merely  such  natural  principles 
of  certain  operations  as  are  their  natural  powers,  but  some- 
thing over  and  above  these,  such  as  habits  inclining  themi 
like  a  second  nature  to  particular  kinds  of  operations,  so 
that  the  operations  become  sources  of  pleasure.  Thus,  as 
by  a  similitude,  any  kind  of  work  in  which  a  man  takes 
delight,  so  that  his  bent  is  towards  it,  his  time  spent  in  it, 
and  his  whole  life  ordered  with  a  view  to  it,  is  said  to  be 
the  life  of  that  man.  Hence  some  are  said  to  lead  a  life  of 
self-indulgence,  others  a  life  of  virtue.  In  this  way  the 
contemplative  life  is  distinguished  from  the  active,  and  thus 
to  know  God  is  said  to  be  life  eternal. 

Wherefore  the  Reply  to  the  third  objection  is  clear. 

Third  Article, 
whether  life  is  properly  attributed  to  god  ? 

We  proceed  thus  to  the  Third  Article: — 
Objection  i.  It  seems  that  life  is  not  properly  attributed 
to  God.     For  things  are  said  to  live  inasmuch  as  they  move 


Q.  i8.  Art.  3     THE  "  SUMMA  THEOLOGICA  "  254 

themselves,  as  previously  stated  (A.  2).     But  movement  does 
not  belong  to  God.     Neither  therefore  does  life. 

Obj.  2.  Further,  in  all  living  things  we  must  needs  suppose 
some  principle  of  life.  Hence  it  is  said  by  the  Philosopher 
{De  anima  ii.  4)  that  the  soul  is  the  cause  and  principle  of  the 
living  body.  But  God  has  no  principle.  Therefore  life 
cannot  be  attributed  to  Him. 

Obj.  3.  Further,  the  principle  of  life  in  the  living  things 
that  exist  among  us  is  the  vegetative  soul.  But  this  exists 
only  in  corporeal  things.  Therefore  life  cannot  be  attributed 
to  incorporeal  things. 

On  the  contrary.  It  is  said  (Ps.  Ixxxiii.  3) :  My  heart  and  my 
flesh  have  rejoiced  in  the  living  God. 

I  answer  that,  Life  is  in  the  highest  degree  properly  in 

God.     In  proof  of  which  it  must  be  considered  that  since 

a  thing  is  said  to  live  in  so  far  as  it  operates  of  itself  and  not 

as  moved  by  another,  the  more  perfectly  this  power  is  found 

in  anything,  the  more  perfect  is  the  life  of  that  thing.     In 

things  that  move  and  are  moved  a  threefold  order  is  found. 

In  the  first  place  the  end  moves  the  agent :  and  the  principal 

agent  is  that  which  acts  through  its  form,  and  sometimes  it 

does  so  through  some  instrument  that  acts  by  virtue  not  of  its 

own  form,  but  of  the  principal  agent,  and  does  no  more  than 

execute  the  action.     Accordingly  there  are  things  that  move 

themselves,  not  in  respect  of   any   form  or  end  naturally 

inherent  in  them,  but  only  in  respect  of  the  executing  of  the 

movement;  the  form  by  which  they  act,  and  the  end  of 

the  action  being  alike  determined  for  them  by  their  nature. 

Of  this  kind  are  plants,  which  move  themselves  according 

to  their  inherent  nature,  with  regard  only  to  executing  the 

movements  of  growth  and  decay. 

Other  things  have  self -movement  in  a  higher  degree, 
that  is,  not  only  with  regard  to  executing  the  movement, 
but  even  as  regards  the  form,  the  principle  of  movement, 
which  form  they  acquire  of  themselves.  Of  this  kind  are 
animals,  in  which  the  principle  of  movement  is  not  a 
naturally  implanted  form ;  but  one  received  through  sense. 
Hence  the  more  perfect  is  their  sense,  the  more  perfect 
is  their  power  of  self -movement.     Such  as  have  only  the 


255  THE  LIFE  OF  GOD  Q.18.ART.3 

sense  of  touch,  as  shellfish,  move  only  with  the  motion  of 
expansion  and  contraction;  and  thus  their  movement 
hardly  exceeds  that  of  plants.  Whereas  such  as  have  the 
sensitive  power  in  perfection,  so  as  to  recognize  not  only 
connection  and  touch,  but  also  objects  apart  from  them- 
selves, can  move  themselves  to  a  distance  by  progressive 
movement.  Yet  although  animals  of  the  latter  kind  receive 
through  sense  the  form  that  is  the  principle  of  their  move- 
ment, nevertheless  they  cannot  of  themselves  propose  to 
themselves  the  end  of  their  operation,  or  movement ;  for  this 
has  been  implanted  in  them  by  nature;  and  by  natural 
instinct  they  are  moved  to  any  action  through  the  form 
apprehended  by  sense.  Hence  such  animals  as  move  them- 
selves in  respect  to  an  end  they  themselves  propose  are 
superior  to  these.  This  can  only  be  done  by  reason  and 
intellect;  whose  province  it  is  to  know  the  proportion  be- 
tween the  end  and  the  means  to  that  end,  and  duly  co- 
ordinate them.  Hence  a  more  perfect  degree  of  life  is  that 
of  intelligent  beings;  for  their  power  of  self -movement  is 
more  perfect.  This  is  shown  by  the  fact  that  in  one  and  the 
same  man  the  intellectual  faculty  moves  the  sensitive 
powers;  and  these  by  their  command  move  the  organs  of 
movement.  Thus  in  the  arts  we  see  that  the  art  of  using  a 
ship,  i.e.,  the  art  of  navigation,  rules  the  art  of  ship-designing; 
and  this  in  its  turn  rules  the  art  that  is  only  concerned  with 
preparing  the  material  for  the  ship. 

But  although  our  intellect  moves  itself  to  some  things,  yet 
others  are  supplied  by  nature,  as  are  first  principles,  which 
it  cannot  doubt ;  and  the  last  end,  which  it  cannot  but  will. 
Hence,  although  with  respect  to  some  things  it  moves  itself, 
yet  with  regard  to  other  things  it  must  be  moved  by  another. 
Wherefore  that  being  whose  act  of  understanding  is  its 
very  nature,  and  which,  in  what  it  naturally  possesses,  is  not 
determined  by  another,  must  have  life  in  the  most  perfect 
degree.  Such  is  God;  and  hence  in  Him  principally  is 
life.  From  this  the  Philosopher  concludes  (Metaph.  xii.  51), 
after  showing  God  to  be  intelligent,  that  God  has  life  most 
perfect  and  eternal,  since  His  intellect  is  most  perfect  and 
always  in  act. 


Q.  i8.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  256 

Reply  Obj.  i.  As  stated  in  Metaph.  ix.  16,  action  is  two- 
fold. Actions  of  one  kind  pass  out  to  external  matter,  as 
to  heat  or  to  cut ;  whilst  actions  of  the  other  kind  remain  in 
the  agent,  as  to  understand,  to  sense,  and  to  will.  The 
difference  between  them  is  this,  that  the  former  action  is  the 
perfection  not  of  the  agent  that  moves,  but  of  the  thing 
moved;  whereas  the  latter  action  is  the  perfection  of  the 
agent.  Hence,  because  movement  is  an  act  of  the  thing 
n  movement,  the  latter  action,  in  so  far  as  it  is  the  act  of 
the  operator,  is  called  its  movement,  by  this  similitude, 
that  as  movement  is  an  act  of  the  thing  moved,  so  an  act  of 
this  kind  is  the  act  of  the  agent,  although  movement  is  an 
act  of  the  imperfect,  that  is,  of  what  is  in  potentiality; 
while  this  kind  of  act  is  an  act  of  the  perfect,  that  is  to  say, 
of  what  is  in  act  as  stated  in  De  anima  iii.  28.  In  the  sense, 
therefore,  in  which  understanding  is  movement,  that  which 
understands  itself  is  said  to  move  itself.  It  is  in  this  sense 
that  Plato  also  taught  that  God  moves  Himself;  not  in  the 
sense  in  which  movement  is  an  act  of  the  imperfect. 

Reply  Obj.  2.  As  God  is  His  own  very  existence  and 
understanding,  so  is  He  His  own  life;  and  therefore  He  so 
Hves  that  He  has  no  principle  of  life. 

Reply  Obj.  3.  Life  in  this  lower  world  is  bestowed  on  a 
corruptible  nature,  that  needs  generation  to  preserve  the 
species,  and  nourishment  to  preserve  the  individual.  For 
this  reason  life  is  not  found  here  below  apart  from  a  vegeta- 
tive soul:  but  this  does  not  hold  good  with  incorruptible 
natures. 

Fourth  Article, 
whether  all  things  are  life  in  god  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  not  all  things  are  life  in  God. 
For  it  is  said  (Acts  xvii.  28),  In  Him  we  live,  and  move,  and 
be.  But  not  all  things  in  God  are  movement.  Therefore 
not  all  things  are  life  in  Him. 

Obj.  2.  Further,  all  things  are  in  God  as  their  first  model. 
But  things  modelled  ought  to  conform  to  the  model.     Since, 


257  THE  LIFE  OF  GOD  Q.  i8.  Art.  4 

then,  not  all  things  have  life  in  themselves,  it  seems  that  not 
all  things  are  life  in  God. 

Ohj.  3.  Further,  as  Augustine  says  (De  vera  relig.  29), 
a  living  substance  is  better  than  a  substance  that  does  not 
live.  If,  therefore,  things  which  in  themselves  have  not  life, 
are  life  in  God,  it  seems  that  things  exist  more  truly  in  God 
than  in  themselves.  But  this  appears  to  be  false;  since  in 
themselves  they  exist  actually,  but  in  God  potentially. 

Obj.  4.  Further,  just  as  good  things  and  things  made  in 
time  are  known  by  God,  so  are  bad  things,  and  things  that 
God  can  make,  but  that  never  will  be  made.  If,  therefore, 
all  things  are  life  in  God,  inasmuch  as  known  by  Him,  it 
seems  that  even  bad  things  and  things  that  will  never  be 
made  are  life  in  God,  as  known  by  Him,  and  this  appears 
inadmissible. 

On  the  contrary  (John  i.  3,  4),  It  is  said,  What  was  made,  in 
Him  was  life.  But  all  things  were  made,  except  God. 
Therefore  all  things  are  life  in  God. 

/  answer  that,  In  God  to  live  is  to  understand,  as  before 
stated  (A.  3).  In  God  intellect,  the  thing  understood,  and 
the  act  of  understanding,  are  one  and  the  same.  Hence 
whatever  is  in  God  as  understood  is  the  very  living  or  life 
of  God.  Now,  wherefore,  since  all  things  that  have  been 
made  by  God  are  in  Him  as  things  understood,  it  follows 
that  all  things  in  Him  are  the  divine  life  itself. 

Reply  Obj.  1.  Creatures  are  said  to  be  in  God  in  a  two- 
fold sense.  In  one  way,  so  far  as  they  are  held  together 
and  preserved  by  the  divine  power;  even  as  we  say  that 
things  that  are  in  our  power  are  in  us.  And  creatures  are 
thus  said  to  be  in  God,  even  as  they  exist  in  their  own 
natures.  In  this  sense  we  must  understand  the  words  of  the 
Apostle  when  he  says,  In  Him  we  live,  and  move,  and  be; 
since  our  being,  living,  and  moving  are  themselves  caused 
by  God.  In  another  sense  things  are  said  to  be  in  God, 
as  in  Him  who  knows  them,  in  which  sense  they  are  in 
God  through  their  proper  ideas,  which  in  God  are  not  dis- 
tinct from  the  divine  essence.  Hence  things  as  they  are  in 
God  are  the  divine  essence.  And  since  the  divine  essence 
I.  17 


0.  i8.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  258 

is  life  and  not  movement,  it  follows  that  things  existing  in 
God  in  this  manner  are  not  movement,  but  life. 

Reply  Ohj,  2.  The  thing  modelled  must  be  like  the  model 
according  to  the  form,  not  the  mode  of  being.  For  sometimes 
the  form  has  being  of  another  kind  in  the  model  from  that 
which  it  has  in  the  thing  modelled.  Thus  the  form  of  a 
house  has  in  the  mind  of  the  architect  immaterial  and 
intelligible  being;  but  in  the  house  that  exists  outside  his 
mind,  material  and  sensible  being.  Hence  the  ideas  of 
things,  though  not  existing  in  themselves,  are  life  in  the 
divine  mind,  as  having  a  divine  existence  in  that  mind. 

Reply  Ohj.  3.  If  form  only,  and  not  matter,  belonged  to 
natural  things,  then  in  all  respects  natural  things  would  exist 
more  truly  in  the  divine  mind,  by  the  ideas  of  them,  than  in 
themselves.  For  which  reason,  in  fact,  Plato  held  that  the 
separate  man  was  the  true  man;  and  that  man  as  he  exists 
in  matter,  is  man  only  by  participation.  But  since  matter 
enters  into  the  being  of  natural  things,  we  must  say  that 
those  things  have  simply  being  in  the  divine  mind  more 
truly  than  in  themselves,  because  in  that  mind  they  have 
an  uncreated  being,  but  in  themselves  a  created  being: 
whereas  this  particular  being,  a  man,  or  a  horse,  for  example, 
has  this  being  more  truly  in  its  own  nature  than  in  the 
divine  mind,  because  it  belongs  to  human  nature  to  be 
material,  which,  as  existing  in  the  divine  mind,  it  is  not. 
Even  so  a  house  has  nobler  being  in  the  architect's  mind 
than  in  matter;  yet  a  material  house  is  called  a  house  more 
truly  than  the  one  which  exists  in  the  mind ;  since  the  former 
is  actual,  the  latter  only  potential. 

Reply  Ohj.  4.  Although  bad  things  are  in  God's  know- 
ledge, as  being  comprised  under  that  knowledge,  yet  they 
are  not  in  God  as  created  by  Him,  or  preserved  by  Him,  or 
as  having  their  type  in  Him.  They  are  known  by  God 
through  the  types  of  good  things.  Hence  it  cannot  be  said 
that  bad  things  are  life  in  God.  Those  things  that  are  not 
in  time  may  be  called  life  in  God  in  so  far  as  life  means  under- 
standing only,  and  inasmuch  as  they  are  understood  by  God; 
but  not  in  so  far  as  life  implies  a  principle  of  operation. 


QUESTION  XIX. 

THE   WILL   OF    GOD. 
{In  Twelve  Articles.) 

After   considering   the   things    belonging   to   the   divine 

knowledge,  we  consider  what  belongs  to  the  divine  will. 

The  first  consideration  is  about  the  divine  will  itself;  the 

second  about  what  belongs  strictly  to  His  will;  the  third 

about  what  belongs  to  the  intellect  in  relation  to  His  will. 

About  His  will  itself  there  are  twelve  points  of  inquiry: 

(i)  Whether  there  is  will  in  God  ?     (2)  Whether  God  wills 

things  apart  from  Himself  ?     (3)  Whether  whatever  God 

wills,  He  wills  necessarily  ?     (4)  Whether  the  will  of  God 

is  the  cause  of  things  ?     (5)  Whether  any  cause  can  be 

assigned  to  the  divine  will  ?     (6)  Whether  the  divine  will 

is    always    fulfilled  ?     (7)    Whether    the    will    of    God    is 

mutable  ?     (8)  Whether  the  will  of  God  imposes  necessity 

on  the  things  willed  ?     (9)  Whether  there  is  in  God  the  will 

of  evil  ?     (10)  Whether  God  has  free  will  ?     (11)  Whether  the 

will  of  expression  is  distinguished  in  God  ?     (12)  Whether 

five  expressions  of  will  are  rightly  assigned  to  the  divine 

will  ? 

First  Article, 
whether  there  is  will  in  god  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  there  is  not  will  in  God.  For 
the  object  of  will  is  the  end  and  the  good.  But  we  cannot 
assign  to  God  any  end.  Therefore  there  is  not  will  in 
God. 

Ohj.  2.  Further,  will  is  a  kind  of  appetite.  But  appetite, 
as  it  is  directed  to  things  not  possessed,  implies  imperfec- 

259 


Q.  19.  Art.  i     THE  ''  SUMMA  THEOLOGICA  "  260 

tion,  which  cannot  be  imputed  to  God.     Therefore  there 
is  not  will  in  God. 

Ohj.  3.  Further,  according  to  the  Philosopher  {De  anima 
iii.  54),  the  will  moves,  and  is  moved.  But  God  is  the  first 
cause  of  movement,  and  Himself  is  unmoved,  as  proved  in 
Phys.  viii.  49.     Therefore  there  is  not  will  in  God. 

On  the  contrary,  The  Apostle  says  (Rom.  xii.  2) :  That  you 
may  prove  what  is  the  will  of  God. 

I  answer  that,  There  is  will  in  God,  as  there  is  intellect : 
since  will  follows  upon  intellect.  For  as  natural  things 
have  actual  existence  by  their  form,  so  the  intellect  is  actually 
intelligent  by  its  intelligible  form.  Now  everything  has 
this  aptitude  towards  its  natural  form,  that  when  it  has  it 
not  it  tends  towards  it ;  and  when  it  has  it,  it  is  at  rest  therein. 
It  is  the  same  with  every  natural  perfection,  which  is  a 
natural  good.  This  aptitude  to  good  in  things  without  know- 
ledge is  called  natural  appetite.  Whence  also  intellectual 
natures  have  a  like  aptitude  to  good  as  apprehended  through 
its  intelligible  form;  so  as  to  rest  therein  when  possessed, 
and  when  not  possessed  to  seek  to  possess  it,  both  of  which 
pertain  to  the  will.  Hence  in  ever  intellectual  being  there  is 
will,  just  as  in  every  sensible  being  there  is  animal  appetite. 
And  so  there  must  be  will  in  God,  since  there  is  intellect  in 
Him.     And  as  His  intellect  is  His  own  existence,  so  is  His  will. 

Reply  Ohj.  i.  Although  nothing  apart  from  God  is  His 
end,  yet  He  Himself  is  the  end  with  respect  to  all  things 
made  by  Him.  And  this  by  His  essence,  for  by  His  essence 
He  is  good,  as  shown  above  (Q.  VL,  A.  3) :  for  the  end  has 
the  aspect  of  good. 

Reply  Ohj.  2.  Will  in  us  belongs  to  the  appetitive  part, 
which,  although  named  from  appetite,  has  not  for  its  only 
act  the  seeking  what  it  does  not  possess ;  but  also  the  loving 
and  delighting  in  what  it  does  possess.  In  this  respect  will 
is  said  to  be  in  God,  as  having  always  good  which  is  its  object, 
since,  as  already  said,  it  is  not  distinct  from  His  essence. 

Reply  Ohj.  3.  A  will  of  which  the  principal  object  is  a 
good  outside  itself,  must  be  moved  by  another:  but  the 
object  of  the  divine  will  is  His  goodness,  which  is  His 


26i  THE  WILL  OF  GOD  Q.  19.  Art.  2 

essence.  Hence,  since  the  will  of  God  is  His  essence,  it 
is  not  moved  by  another  than  itself,  but  by  itself  alone, 
in  the  same  sense  as  understanding  and  willing  are  said  to 
be  movement.  This  is  what  Plato  meant  when  he  said 
that  the  first  mover  moves  itself. 


Second  Article, 
whether  god  wills  things  apart  from  himself  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  God  does  not  will  things  apart 
from  Himself.  For  the  divine  will  is  the  divine  existence. 
But  God  is  not  other  than  Himself.  Therefore  He  does 
not  will  things  other  than  Himself. 

Ohj.  2.  Further,  the  willed  moves  the  wilier,  as  the  appe- 
tible  the  appetite,  as  stated  in  De  anima  iii.  54.  If,  there- 
fore, God  wills  anything  apart  from  Himself,  His  will  must 
be  moved  by  another ;  which  is  impossible. 

Ohj.  3.  Further,  if  what  is  willed  suffices  the  wilier,  he 
seeks  nothing  beyond  it.  But  His  own  goodness  suffices 
God,  and  completely  satisfies  His  will.  Therefore  God 
does  not  will  anything  apart  from  Himself. 

Ohj.  4.  Further,  acts  of  the  will  are  multiplied  in  propor- 
tion to  the  number  of  their  objects.  If,  therefore,  God  wills 
Himself  and  things  apart  from  Himself,  it  follows  that  the 
act  of  His  will  is  manifold,  and  consequently  His  existence, 
which  is  His  will.  But  this  is  impossible.  Therefore  God 
does  not  will  things  apart  from  Himself. 

On  the  contrary,  The  Apostle  says  (i  Thess.  iv.  3) :  This  is 
the  will  of  God,  your  sanctification. 

I  answer  that,  God  wills  not  only  Himself,  but  other 
things  apart  from  Himself.  This  is  clear  from  the  com- 
parison which  we  made  above  (A.  i).  For  natural  things 
have  a  natural  inclination  not  only  towards  their  own  proper 
good,  to  acquire  it  if  not  possessed,  and,  if  possessed,  to  rest 
therein;  but  also  to  spread  abroad  their  own  good  amongst 
others,  so  far  as  possible.  Hence  we  see  that  every  agent, 
in  so  far  as  it  is  perfect  and  in  act,  produces  its  like.     It 


Q.  19.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  262 

pertains,  therefore,  to  the  nature  of  the  will  to  communicate 
as  far  as  possible  to  others  the  good  possessed ;  and  especially 
does  this  pertain  to  the  divine  will,  from  which  all  perfection 
is  derived  in  some  kind  of  likeness.  Hence,  if_  natural 
things,  in  so  far  as  they  are  perfect,  communicate  their 
good  to  others,  much  more  does  it  appertain  to  the  divine 
will  to  communicate  by  likeness  its  own  good  to  others, 
as  much  as  is  possible.  Thus,  then.  He  wills  both  Himself 
to  be,  and  other  things  to  be;  but  Himself  as  the  end,  and 
other  things  as  ordained  to  that  end;  inasmuch  as  it  befits 
the  divine  goodness  that  other  things  should  be  partakers 
therein. 

Reply  Ohj.  i.  The  divine  will  is  God's  own  e^^istence 
essentially,  yet  they  differ  in  aspect,  according  to  the 
different  ways  of  understanding  them  and  expressing  them, 
as  is  clear  from  what  has  been  already  said  (Q.  XIII.,  A.  4). 
For  when  we  say  that  God  exists,  no  relation  to  any  other 
object  is  implied,  as  we  do  imply  when  we  say  that  God 
wills.  Therefore,  although  He  is  not  anything  apart  from 
Himself,  yet  He  does  will  things  apart  from  Himself. 

Reply  Ohj.  2.  In  things  willed  for  the  sake  of  the  end, 
the  whole  reason  for  our  being  moved  is  the  end,  and  this 
it  is  that  moves  the  will,  as  most  clearly  appears  in  things 
willed  only  for  the  sake  of  the  end.  He  who  wills  to  take  a 
bitter  draught,  in  doing  so  wills  nothing  else  than  health;  and 
this  alone  moves  his  will.  It  is  different  with  one  who  takes 
a  draught  that  is  pleasant,  which  anyone  may  will  to  do,  not 
only  for  the  sake  of  health,  but  also  for  its  own  sake.  Hence, 
although  God  wills  things  apart  from  Himself  only  for  the 
sake  of  the  end,  which  is  His  own  goodness,  it  does  not 
follow  that  anything  else  moves  His  will,  except  His  good- 
ness. So,  as  He  understands  things  apart  from  Himself 
by  understanding  His  own  essence,  so  He  wills  things 
apart  from  Himself  by  willing  His  own  goodness. 
-  Reply  Ohj.  3.  From  the  fact  that  His  own  goodness 
suffices  the  divine  will,  it  does  not  follow  that  it  wills  nothing 
apart  from  itself,  but  rather  that  it  wills  nothing  except  by 
reason  of  its  goodness.     Thus,   too,   the  divine  intellect.

though  its  perfection  consists  in  its  very  knowledge  of  the 
divine  essence,  yet  in  that  essence  knows  other  things. 

Reply  Ohj.  4.  As  the  divine  intellect  is  one,  as  seeing  the 
many  only  in  the  one,  in  the  same  way  the  divine  will  is  one 
and  simple,  as  willing  the  many  only  through  tjie  one,  that 
is,  through  its  own  goodness. 

Third  Article. 

whether  whatever  god  wills  he  wills  neces- 
SARILY ?       , 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  whatever  God  wills  He  wills 
necessarily.  For  everything  eternal  is  necessary.  But 
whatever  God  wills,  He  wills  from  eternity,  for  otherwise 
His  will  would  be  mutable.  Therefore  whatever  He  wills. 
He  wills  necessarily. 

Ohj,  2.  Further,  God  wills  things  apart  from  Himself. 
inasmuch  as  He  wills  His  own  goodness.  Now  God  wills 
His  own  goodness  necessarily.  Therefore  He  wills  things 
apart  from  Himself  necessarily. 

Ohj.  3.  Further,  whatever  belongs  to  the  nature  of  God 
is  necessary,  for  God  is  of  Himself  necessary  being,  and  the 
principle  of  all  necessity,  as  above  shown  (Q.  IL,  A.  3).  But 
it  belongs  to  His  nature  to  will  whatever  He  wills;  since 
in  God  there  can  be  nothing  over  and  above  His  nature 
as  stated  in  Metaph.  v.  6.  Therefore  whatever  He  wills. 
He  wills  necessarily. 

Ohj.  4.  Further,  being  that  is  not  necessary,  and  being 
that  is  possible  not  to  be,  are  one  and  the  same  thing. 
If,  therefore,  God  does  not  necessarily  will  a  thing  that  He 
wills,  it  is  possible  for  Him  not  to  will  it,  and  therefore 
possible  for  Him  to  will  what  He  does  not  will.  And  so  the 
divine  will  is  contingent  upon  one  or  the  other  of  two  things, 
and  imperfect,  since  everything  contingent  is  imperfect  and 
mutable. 

Ohj.  5.  Further,  on  the  part  of  that  which  is  indifferent 
to  one  or  the  other  of  two  things,  no  action  results  unless  it 


Q.  19.  Art.  3    THE  ''  SUMMA  THEOLOGICA  "  264 

is  inclined  to  one  or  the  other  by  some  other  power,  as  the 
Commentator*  says  on  Phys.  ii.  If,  then,  the  Will  of  God  is 
indifferent  with  regard  to  anything,  it  follows  that  His 
determination  to  act  comes  from  another;  and  thus  He  has 
some  cause  prior  to  Himself. 

Ohj.  6.  Further,  whatever  God  knows,  He  knows  neces- 
sarily. But  as  the  divine  knowledge  is  His  essence,  so  is 
the  divine  will.  Therefore  whatever  God  wills.  He  wills 
necessarily. 

On  the  contrary,  The  Apostle  says  (Eph.  i.  11):  Who 
worketh  all  things  according  to  the  counsel  of  His  will.  Now, 
what  we  work  according  to  the  counsel  of  the  will,  we  do  not 
will  necessarily.  Therefore  God  does  not  will  necessarily 
whatever  He  wills. 

/  answer  that,  There  are  two  ways  in  which  a  thing  is 
said  to  be  necessary,  namely,  absolutely,  and  by  supposition. 
We  judge  a  thing  to  be  absolutely  necessary  from  the  relation 
of  the  terms,  as  when  the  predicate  forms  part  of  the  defini- 
tion of  the  subject :  thus  it  is  absolutely  necessary  that  man 
is  an  animal.  It  is  the  same  when  the  subject  forms  part 
of  the  notion  of  the  predicate;  thus  it  is  absolutely  neces- 
sary that  a  number  must  be  odd  or  even.  In  this  way  it 
is  not  necessary  that  Socrates  sits :  wherefore  it  is  not  neces- 
sary absolutely,  though  it  may  be  so  by  supposition;  for, 
granted  that  he  is  sitting,  he  must  necessarily  sit,  as  long  as 
he  is  sitting.  Accordingly  as  to  things  willed  by  God,  we  must 
observe  that  He  wills  something  of  absolute  necessity:  but 
this  is  not  true  of  all  that  He  wills.  For  the  divine  will  has 
a  necessary  relation  to  the  divine  goodness,  since  that  is  its 
proper  object.  Hence  God  wills  His  own  goodness  neces- 
sarily, even  as  we  will  our  own  happiness  necessarily,  and 
as  any  other  faculty  has  necessary  relation  to  its  proper 
and  principal  object,  for  instance  the  sight  to  colour,  since 
it  tends  to  it  by  its  own  nature.  But  God  wills  things  apart 
from  Himself  in  so  far  as  they  are  ordered  to  His  own  good- 
ness as  their  end.  Now  in  willing  an  end  we  do  not  necessarily 
>yill  things  that  conduce  to  it,  unless  they  are  such  that  the 

*  i^.verroes. 


265  THE  WILL  OF  GOD  Q.  19.  Art.  3 

end  cannot  be  attained  without  them ;  as,  we  will  to  take  food 
to  preserve  life,  or  to  take  ship  in  order  to  cross  the  sea. 
But  we  do  not  necessarily  will  things  without  which  the  end 
is  attainable,  such  as  a  horse  for  a  journey  which  we  can  take 
on  foot,  for  we  can  make  the  journey  without  one.  The 
same  applies  to  other  means.  Hence,  since  the  goodness 
of  God  is  perfect,  and  can  exist  without  other  things  inas- 
much as  no  perfection  can  accrue  to  Him  from  them,  it 
follows  that  His  willing  things  apart  from  Himself  is  not  abso- 
lutely necessary.  Yet  it  can  be  necessary  by  supposition, 
for  supposing  that  He  wills  a  thing,  then  He  is  unable  not 
to  will  it,  as  His  will  cannot  change. 

Reply  Obj.  i.  From  the  fact  that  God  wills  from  eternity 
whatever  He  wills,  it  does  not  follow  that  He  wills  it  neces- 
sarily; except  by  supposition. 

Reply  Obj.  2.  Although  God  necessarily  wills  His  own 
goodness,  He  does  not  necessarily  will  things  willed  on 
account  of  His  goodness;  for  it  can  exist  without  other 
things. 

Reply  Obj.  3.  It  is  not  natural  to  God  to  will  any  of  those 
other  things  that  He  does  not  will  necessarily;  and  yet  it  is 
not  unnatural  or  contrary  to  His  nature,  but  voluntary. 

Reply  Obj.  4.  Sometimes  a  necessary  cause  has  a  non- 
necessary  relation  to  an  effect;  owing  to  a  deficiency  in  the 
effect,  and  not  in  the  cause.  Even  so,  the  sun's  power  has 
a  non-necessary  relation  to  some  contingent  events  on  this 
earth,  owing  to  a  defect  not  in  the  solar  power,  but  in 
the  effect  that  proceeds  not  necessarily  from  the  cause.  In 
the  same  way,  that  God  does  not  necessarily  will  some  of  the 
things  that  He  wills,  does  not  result  from  defect  in  the 
divine  will,  but  from  a  defect  belonging  to  the  nature  of 
the  thing  willed,  namely,  that  the  perfect  goodness  of  God  can 
be  without  it ;  and  such  defect  accompanies  all  created  good. 

Reply  Obj.  5.  A  naturally  contingent  cause  must  be 
determined  to  act  by  some  external  power.  The  divine 
will,  which  by  its  nature  is  necessary,  determines  itself  to 
vAll  things  to  which  it  has  no  necessary  relation. 

Reply   Obj.   6.  As   the   divine  existence   is   necessary   of 


Q.  19.  Art.  4    THE  "  SUMMA  THEOLOGICA  ''  266 

itself,  so  is  the  divine  will  and  the  divine  knowledge;  but 
the  divine  knowledge  has  a  necessary  relation  to  the  thing 
known;  not  the  divine  will  to  the  thing  willed.  The  reason 
for  this  is  that  knowledge  is  of  things  as  they  exist  in  the 
knower;  but  the  will  is  directed  to  things  as  they  exist  in 
themselves.  Since  then  all  other  things  have  necessary  exist- 
ence inasmuch  as  they  exist  in  God ;  but  no  absolute  neces- 
sity so  as  to  be  necessary  in  themselves,  in  so  far  as  they 
exist  in  themselves;  it  follows  that  God  knows  necessarily 
whatever  He  knows,  but  does  not  will  necessarily  whatever 
He  wills. 

Fourth  Article, 
whether  the  will  of  god  is  the  cause  of  things  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  the  will  of  God  is  not  the  cause 
of  things.  For  Dionysius  says  {Div.  Nom.  iv.  1):  As  our  sun, 
not  by  reason  nor  by  pre-election,  but  by  its  very  being,  en- 
lightens all  things  that  can  participate  in  its  light,  so  the  divine 
good  by  its  very  essence  pours  the  rays  of  its  goodness  upon 
everything  that  exists.  But  every  voluntary  agent  acts  by 
reason  and  pre-election.  Therefore  God  does  not  act  by 
will;  and  so  His  will  is  not  the  cause  of  things. 

Obj.  2.  Further,  The  first  in  any  order  is  that  which  is 
essentially  so,  thus  in  the  order  of  burning  things,  that  comes 
first  which  is  fire  by  its  essence.  But  God  is  the  first  agent. 
Therefore  He  acts  by  His  essence;  and  that  is  His  nature. 
He  acts  then  by  nature,  and  not  by  will.  Therefore  the 
divine  will  is  not  the  cause  of  things. 

Obj.  3.  Further,  whatever  is  the  cause  of  anything, 
through  being  such  a  thing,  is  the  cause  by  nature,  and  not 
by  will.  For  fire  is  the  cause  of  heat,  as  being  itself  hot; 
whereas  an  architect  is  the  cause  of  a  house,  because  he 
wills  to  build  it.  Now  Augustine  says  {De  Doct.  Christ,  i.  32), 
Because  God  is  good,  we  exist.  Therefore  God  is  the  cause  of 
things  by  His  nature,  and  not  by  His  will. 

Obj.  4.  Further,  Of  one  thing  there  is  one  cause.  But 
the  cause  of  created  things  is  the  knowledge  of  God,  as 


267  THE  WILL  OF  GOD  Q.  19.  Art.  4 

said  before  (Q.  XIV.,  A.  8).     Therefore  the  will  of  God 
cannot  be  considered  the  cause  of  things. 

On  the  contrary,  It  is  said  (Wis.  xi.  26),  How  could  anything 
endure,  if  Thou  wouldst  not  ? 

I  answer  that,  We  must  hold  that  the  will  of  God  is  the 
cause  of  things;  and  that  He  acts  by  the  will,  and  not,  as 
some  have  supposed,  by  a  necessity  of  His  nature. 

This  can  be  shown  in  three  ways:  First,  from  the  order 
itself  of  active  causes.  Since  both  intellect  and  nature  act 
for  an  end,  as  proved  in  Phys.  ii.  49,  the  natural  agent  must 
have  the  end  and  the  necessary  means  predetermined  for  it 
by  some  higher  intellect;  as,  the  end  and  definite  movement 
is  predetermined  for  the  arrow  by  the  archer.  Hence  the 
intellectual  and  voluntary  agent  must  precede  the  agent  that 
acts  by  nature.  Hence,  since  God  is  first  in  the  order  of 
agents.  He  must  act  by  intellect  and  will. 

This  is  shown,  secondly,  from  the  character  of  a  natural 
agent,  of  which  the  property  is  to  produce  one  and  the 
same  effect;  for  nature  operates  in  one  and  the  same  way, 
unless  it  be  prevented.  This  is  because  the  nature  of 
the  act  is  according  to  the  nature  of  the  agent;  and  hence 
as  long  as  it  has  that  nature,  its  acts  will  be  in  accordance 
with  that  nature;  for  every  natural  agent  has  a  determinate 
being.  Since,  then,  the  Divine  Being  is  undetermined,  and 
contains  in  Himself  the  full  perfection  of  being,  it  cannot 
be  that  He  acts  by  a  necessity  of  His  nature,  unless  He 
were  to  cause  something  undetermined  and  indefinite  in 
being:  and  that  this  is  impossible  has  been  already  shown 
(Q.  VII.,  A.  2).  He  does  not,  therefore,  act  by  a  necessity 
of  His  nature,  but  determined  effects  proceed  from  His  own 
infinite  perfection  according  to  the  determination  of  His 
will  and  intellect. 

Thirdly,  it  is  shown  by  the  relation  of  effects  to  their 
cause.  For  effects  proceed  from  the  agent  that  causes  them, 
in  so  far  as  they  pre-exist  in  the  agent;  since  every  agent 
produces  its  like.  Now  effects  pre-exist  in  their  cause 
after  the  mode  of  the  cause.  Wherefore  since  the  Divine 
Being  is  His  own  intellect,  effects  pre-exist  in  Him  after  the 


Q.  19.  Art.  5    THE  "  SUMMA  THEOLOGICA  "  268 

mode  of  intellect,  and  therefore  proceed  from  Him  after  the 
same  mode.  Consequently,  they  proceed  from  Him  after 
the  mode  of  will,  for  His  inclination  to  put  in  act  what 
His  intellect  has  conceived  appertains  to  the  will.  There- 
fore the  will  of  God  is  the  cause  of  things. 

Reply  Obj.  1.  Dionysius  in  these  words  does  not  intend  to 
exclude  election  from  God  absolutely;  but  only  in  a  certain 
sense,  in  so  far,  that  is,  as  He  communicates  His  goodness 
not  merely  to  certain  beings,  but  to  all;  and  as  election 
implies  a  certain  distinction. 

Reply  Obj.  2.  Because  the  essence  of  God  is  His  intellect 
and  will,  from  the  fact  of  His  acting  by  His  essence,  it 
follows  that  He  acts  after  the  mode  of  intellect  and  will. 

Reply  Obj.  3.  Good  is  the  object  of  the  will.  The  words, 
therefore,  Because  God  is  good,  we  exist,  are  true  inasmuch 
as  His  goodness  is  the  reason  of  His  willing  all  other  things, 
as  said  before  (A.  2,  ad  2). 

Reply  Obj.  4.  Even  in  us  the  cause  of  one  and  the  same 
effect  is  knowledge  as  directing  it,  whereby  the  form  of 
the  work  is  conceived,  and  will  as  commanding  it,  since  the 
form  as  it  is  in  the  intellect  only  is  not  determined  to  exist 
or  not  to  exist  in  the  effect,  except  by  the  will.  Hence, 
the  speculative  intellect  has  nothing  to  say  to  operation. 
But  the  power  is  cause,  as  executing  the  effect,  since  it 
denotes  the  immediate  principle  of  operation.  But  in  God 
all  these  things  are  one. 


Fifth  Article, 
whether  any  cause  can  be  assigned  to  the  divine 

WILL  ? 

We  proceed  thus  to  the  Fifth  Article  : — 

Objection  i.  It  seems  that  some  cause  can  be  assigned  to 
the  divine  will.  For  Augustine  says  {Qq.  Ixxxiii.  46) :  Who 
would  venture  to  say  that  God  made  all  things  irrationally  ? 
But  to  a  voluntary  agent,  what  is  the  reason  of  operating, 
is  the  cause  of  wilHng.  Therefore  the  will  of  God  has  some 
cause. 


269  THE  WILL  OF  GOD  Q.  19.  Art.  5 

Ohj.  2.  Further,  in  things  made  by  one  who  wills  to 
make  them,  and  whose  will  is  influenced  by  no  cause,  there 
can  be  no  cause  assigned  except  the  will  of  him  who  wills. 
But  the  will  of  God  is  the  cause  of  all  things,  as  has  been 
already  shown  (A.  4).  If,  then,  there  is  no  cause  of  His  will, 
we  cannot  seek  in  any  natural  things  any  cause,  except  the 
divine  will  alone.  Thus  all  science  would  be  in  vain,  since 
science  seeks  to  assign  causes  to  effects.  This  seems  inad- 
missible, and  therefore  we  must  assign  some  cause  to  the 
divine  will. 

Ohj.  3.  Further,  what  is  done  by  the  wilier,  on  account 
of  no  cause,  depends  simply  on  his  will.  If,  therefore,  the 
will  of  God  has  no  cause,  it  follows  that  all  things  made 
depend  simply  on  His  will,  and  have  no  other  cause.  But 
this  also  is  not  admissible. 

On  the  contrary,  Augustine  says  {Qq.  Ixxxiii.  28):  Every 
efficient  cause  is  greater  than  the  thing  effected.  But  nothing 
is  greater  than  the  will  of  God.  We  must  not  then  seek  for 
a  cause  of  it. 

/  answer  that,  In  no  wise  has  the  will  of  God  a  cause.  In 
proof  of  which  we  must  consider  that,  since  the  will  follows 
from  the  intellect,  there  is  a  cause  of  the  will  in  the  person 
that  wills,  in  the  same  way  as  there  is  a  cause  of  the  under- 
standing, in  the  person  that  understands.  The  case  with 
the  understanding  is  this:  that  if  the  premiss  and  its  con- 
clusion are  understood  separately  from  each  other,  the 
understanding  the  premiss  is  the  cause  that  the  conclusion 
is  known.  If  the  understanding  perceive  the  conclusion  in 
the  premiss  itself,  apprehending  both  the  one  and  the  other 
at  the  same  glance,  in  this  case  the  knowing  of  the  conclusion 
would  not  be  caused  by  understanding  the  premisses,  since 
a  thing  cannot  be  its  own  cause;  and  yet,  it  would  be  true 
that  the  thinker  would  understand  the  premisses  to  be  the 
cause  of  the  conclusion.  It  is  the  same  with  the  will,  with 
respect  to  which  the  end  stands  in  the  same  relation  to  the 
means  to  the  end,  as  do  the  premisses  to  the  conclusion  with 
regard  to  the  understanding. 

Hence,  if  anyone  in  one  act  wills  an  end,  and  in  another 


Q.  19.  Art.  5     THE  "  SUMMA  THEOLOGICA  "  270 

act  the  means  to  that  end,  his  willing  the  end  will  be  the 
cause  of  his  wilUng  the  means.  This  cannot  be  the  case  if 
in  one  act  he  wills  both  end  and  means;  for  a  thing  cannot 
be  its  own  cause.  Yet  it  will  be  true  to  say  that  he  wills  to 
order  to  the  end  the  means  to  the  end.  Now  as  God  by  one 
act  understands  all  things  in  His  essence,  so  by  one  act  He 
wills  all  things  in  His  goodness.  Hence,  as  in  God  to  under- 
stand the  cause  is  not  the  cause  of  His  understanding  the 
effect,  for  He  understands  the  effect  in  the  cause,  so,  in  Him, 
to  will  an  end  is  not  the  cause  of  His  willing  the  means,  yet 
He  wills  the  ordering  of  the  means  to  the  end.  Therefore 
He  wills  this  to  be  as  means  to  that;  but  does  not  will  this 
on  account  of  that. 

Reply  Ohj.  i.  The  will  of  God  is  reasonable,  not  because 
anything  is  to  God  a  cause  of  willing,  but  in  so  far  as  He 
wills  one  thing  to  be  on  account  of  another. 

Reply  Ohj.  2.  Since  God  wills  effects  to  proceed  from 
definite  causes,  for  the  preservation  of  order  in  the  universe, 
it  is  not  unreasonable  to  seek  for  causes  secondary  to  the 
divine  will.  It  would,  however,  be  unreasonable  to  do  so,  if 
^uch  were  considered  as  primary,  and  not  as  dependent  on 
the  will  of  God.  In  this  sense  Augustine  says  [De  Trin. 
iii.  2) :  Philosophers  in  their  vanity  have  thought  fit  to  attribute 
contingent  effects  to  other  causes,  being  utterly  unable  to  perceive 
the  cause  that  is  above  all  others,  the  will  of  God. 

Reply  Obj.  3.  Since  God  wills  effects  to  come  from  causes, 
all  effects  that  presuppose  some  other  effect  do  not  depend 
solely  on  the  will  of  God,  but  on  something  else  besides: 
but  the  first  effect  depends  on  the  divine  will  alone.  Thus, 
for  example,  we  may  say  that  God  willed  man  to  have 
hands  to  serve  his  intellect  by  their  work,  and  intellect, 
that  he  might  be  man;  and  willed  him  to  be  man  that  he 
might  enjoy  Him,  or  for  the  completion  of  the  universe. 
But  this  cannot  be  reduced  to  other  created  secondary  ends. 
Hence  such  things  depend  on  the  simple  will  of  God;  but 
the  others  on  the  order  of  other  causes. 


271  THE  WILL  OF  GOD  Q.  19.  Art.  6 


Sixth  Article, 
whether  the  will  of  god  is  always  fulfilled  ? 

We  proceed  thus  to  the  Sixth  Article  : — 

Objection  i.  It  seems  that  the  will  of  God  is  not  always 
fulfilled.  For  the  Apostle  says  (i  Tim.  ii.  4) :  God  will  have 
all  men  to  he  saved,  and  to  come  to  the  knowledge  of  the  truth. 
But  this  does  not  happen.  Therefore  the  will  of  God  is  not 
always  fulfilled. 

Obj.  2.  Further,  as  is  the  relation  of  knowledge  to  truth,, 
so  is  that  of  the  will  to  good.  Now  God  knows  all  truth. 
Therefore  He  wills  all  good.  But  not  all  good  actually 
exists;  for  much  more  good  might  exist.  Therefore  the  will 
of  God  is  not  always  fulfilled. 

Obj.  3.  Further,  since  the  will  of  God  is  the  first  cause,  it 
does  not  exclude  intermediate  causes.  But  the  effect  of  a 
first  cause  may  be  hindered  by  a  defect  of  a  secondary  cause ; 
as  the  effect  of  the  motive  power  may  be  hindered  by  weak- 
ness of  the  limb.  Therefore  the  effect  of  the  divine  will 
may  be  hindered  by  a  defect  of  the  secondary  causes.  The 
will  of  God,  therefore,  is  not  always  fulfilled. 

On  the  contrary,  It  is  said  (Ps.  cxiii.  11) :  God  hath  done  all 
things,  whatsoever  He  would. 

I  answer  that.  The  will  of  God  must  needs  always  be  ful- 
filled. In  proof  of  which  we  must  consider  that  since  an 
effect  is  conformed  to  the  agent  according  to  its  form,  the 
rule  is  the  same  with  active  causes  as  with  formal  causes. 
The  rule  in  forms  is  this:  that  although  a  thing  may  fall 
short  of  any  particular  form,  it  cannot  fall  short  of  the 
universal  form.  For  though  a  thing  may  fail  to  be,  for 
example,  a  man  or  a  living  being,  yet  it  cannot  fail  to  be  a 
being.  Hence  the  same  must  happen  in  active  causes. 
Something  may  fall  outside  the  order  of  any  particular 
active  cause,  but  not  outside  the  order  of  the  universal 
cause;  under  which  all  particular  causes  are  included:  and 
if  any  particular  cause  fails  of  its  effect,  this  is  because  of 
the  hindrance  of  some  other  particular  cause,   which  is 


Q.  19.  Art.  5    THE  ''  SUMMA  THEOLOGICA  "  272 

included  in  the  order  of  the  universal  cause.  Therefore  an 
effect  cannot  possibly  escape  the  order  of  the  universal  cause. 
Even  in  corporeal  things  this  is  clearly  seen.  For  it  may 
happen  that  a  star  is  hindered  from  producing  its  effects ;  yet 
whatever  effect  does  result,  in  corporeal  things,  from  this 
hindrance  of  a  corporeal  cause,  must  be  referred  through 
intermediate  causes  to  the  universal  influence  of  the  first 
heaven.  Since,  then,  the  will  of  God  is  the  universal  cause 
of  all  things,  it  is  impossible  that  the  divine  will  should  not 
produce  its  effect.  Hence  that  which  seems  to  depart  from 
the  divine  will  in  one  order,  returns  into  it  in  another  order ; 
as  does  the  sinner,  who  by  sin  falls  away  from  the  divine  will 
as  much  as  lies  in  him,  yet  falls  back  into  the  order  of  that 
will,  when  by  its  justice  he  is  punished. 

Reply  Obj.  i.  The  words  of  the  Apostle,  God  will  have  all 
men  to  he  saved,  etc.,  can  be  understood  in  three  ways. 
First,  by  a  restricted  application,  in  which  case  they  would 
mean,  as  Augustine  says  [De  prcBd.  sanct.  i.  8:  Enchir.  103), 
God  wills  all  men  to  he  saved  that  are  saved,  not  because  there 
is  no  man  whom  He  does  not  wish  saved,  hut  because  there  is 
no  man  saved  whose  salvation  He  does  not  will.  Secondly, 
they  can  be  understood  as  applying  to  every  class  of  indi- 
viduals, not  to  every  individual  of  each  class;  in  which  case 
they  mean  that  God  wills  some  men  of  every  class  and  con- 
dition to  be  saved,  males  and  females,  Jews  and  Gentiles, 
great  and  small,  but  not  all  of  every  condition.  Thirdly, 
according  to  Damascene  (De  Fide  Orth.  ii.  29),  they  are 
understood  of  the  antecedent  will  of  God;  not  of  the  conse- 
quent will.  This  distinction  must  not  be  taken  as  applying 
to  the  divine  will  itself,  in  which  there  is  nothing  antecedent 
nor  consequent,  but  to  the  things  willed. 

To  understand  this  we  must  consider  that  everything,  in 
so  far  as  it  is  good,  is  willed  by  God.  A  thing  taken  in  its 
primary  sense,  and  absolutely  considered,  may  be  good  or 
evil,  and  yet  when  some  additional  circumstances  are  taken 
into  account,  by  a  consequent  consideration  may  be  changed 
mto  the  contrary.  Thus  that  a  man  should  live  is  good ;  and 
that  a  man  should  be  killed  is  evil,  absolutely  considered. 


373  THE  WILL  OF  GOD  Q.  19.  Art.  7 

But  if  in  a  particular  case  we  add  that  a  man  is  a  murderer  or 
dangerous  to  society,  to  kill  him  is  a  good;  that  he  live  is  an 
evil.  Hence  it  may  be  said  of  a  just  judge,  that  antecedently 
he  wills  all  men  to  live ;  but  consequently  wills  the  murderer 
to  be  hanged.  In  the  same  way  God  antecedently  wills  all 
men  to  be  saved,  but  consequently  wills  some  to  be  damned, 
as  His  justice  exacts.  Nor  do  we  will  simply,  what  we  will 
antecedently,  but  rather  we  will  it  in  a  qualified  manner; 
for  the  will  is  directed  to  things  as  they  are  in  themselves, 
and  in  themselves  they  exist  under  particular  qualifications. 
Hence  we  will  a  thing  simply  inasmuch  as  we  will  it  when  all 
particular  circumstances  are  considered;  and  this  is  what  is 
meant  by  willing  consequently.  Thus  it  may  be  said  that 
a  just  judge  wills  simply  the  hanging  of  a  murderer,  but  in 
a  qualified  manner  he  would  will  him  to  live,  to  wit  inas- 
much as  he  is  a  man.  Such  a  qualified  will  may  be  called  a 
willingness  rather  than  an  absolute  will.  Thus  it  is  clear 
that  whatever  God  simply  wills  takes  place ;  although  what 
He  wills  antecedently  may  not  take  place. 

Reply  Ohj.  3.  An  act  of  the  cognitive  faculty  is  according 
as  the  thing  known  is  in  the  knower;  while  an  act  of  the 
appetitive  faculty  is  directed  to  things  as  they  exist  in 
themselves.  But  all  that  can  have  the  nature  of  being  and 
truth  virtually  exists  in  God,  though  it  does  not  all  exist 
in  created  things.  Therefore  God  knows  all  truth ;  but  does 
not  will  all  good,  except  in  so  far  as  He  wills  Himself,  in 
Whom  all  good  virtually  exists. 

Reply  Ohj.  3.  A  first  cause  can  be  hindered  in  its  effect  by 
deficiency  in  the  secondary  cause,  when  it  is  not  the  universal 
first  cause,  including  within  itself  all  causes;  for  then  the 
effect  could  in  no  way  escape  its  order  And  thus  it  is  with 
the  will  of  God,  as  said  above. 

Seventh  Article, 
whether  the  will  of  god  is  changeable  ? 

We  proceed  thus  to  the  Seventh  Article: — 

Objection  i.  It  seems  that  the  Will  of  God  is  changeable. 

For  the  Lord  says  (Gen.  vi.  7) :  It  repenteth  Me  thai  I  have 
n  18 


Q.  19.  Art.  7     THE  "  SUMMA  THEOLOGICA  "  274 

made  man.  But  whoever  repents  of  what  he  has  done,  has 
a  changeable  will.     Therefore  God  has  a  changeable  will. 

Ohj.  2,.  Further,  it  is  said  in  the  person  of  the  Lord :  I  will 
speak  against  a  nation  and  against  a  kingdom,  to  root  out,  and 
to  pull  down,  and  to  destroy  it;  but  if  that  nation  shall  repent  of 
its  evil,  I  also  will  repent  of  the  evil  that  I  have  thought  to  do  to 
them  (Jer.  xviii.  7,  8).     Therefore  God  has  a  changeable  will. 

Obj,  3.  Further,  whatever  God  does,  He  does  voluntarily. 
But  God  does  not  always  do  the  same  thing,  for  at  one  time 
He  ordered  the  law  to  be  observed,  and  at  another  time 
forbade  it.     Therefore  He  has  a  changeable  will. 

Obj.  4.  Further,  God  does  not  will  of  necessity  what  He 
wills,  as  said  before  (A.  3).  Therefore  He  can  both  will  and 
not  will  the  same  thing.  But  whatever  can  incline  to  either 
of  two  opposites,  is  changeable ;  as  that  which  can  exist  and 
not  exist  is  changeable  substantially;  and  that  which  can 
exist  in  a  place  or  not  in  that  place,  is  changeable  locallyti 
Therefore  God  is  changeable  as  regards  His  will. 

On  the  contrary,  It  is  said:  God  is  not  as  a  man,  that  He 
should  lie,  nor  as  the  son  of  man,  that  He  should  be  changed 
(Num.  xxili.  19). 

I  answer  thut.  The  will  of  God  is  entirely  unchangeable. 
On  this  point  we  must  consider  that  to  change  the  will  is  one 
thing;  to  will  that  certain  things  should  be  changed  is 
another.  It  is  possible  to  will  a  thing  to  be  done  now,  and 
its  contrary  afterwards;  and  yet  for  the  will  to  remain 
permanently  the  same:  whereas  the  will  would  be  changed, 
if  one  should  begin  to  will  what  before  he  had  not  willed; 
or  cease  to  will  what  he  had  willed  before.  This  cannot 
happen,  unless  we  presuppose  change  either  in  the  knowledge 
or  in  the  disposition  of  the  substance  of  the  wilier.  For  since 
the  will  regards  good,  a  man  may  in  two  ways  begin  to 
will  a  thing.  In  one  way  when  that  thing  begins  to  be  good 
for  him,  and  this  does  not  take  place  without  a  change  in 
him.  Thus  when  the  cold  weather  begins,  it  becomes  good 
to  sit  by  the  fire ;  though  it  was  not  so  before.  In  another 
way  when  he  knows  for  the  first  time  that  a  thing  is  good  for 
him,  though  he  did  not  know  it  before:  hence  we  take 


275  THE  WILL  OF  GOD  Q.  19.  Art.  7 

counsel  in  order  to  know  what  is  good  for  us.  Now  it  has 
already  been  shown  that  both  the  substance  of  God  and  His 
knowledge  are  entirely  unchangeable  (QQ.  IX.  A.  i; 
XIV.  A.  15).  Therefore  His  will  must  be  entirely  unchange- 
able. 

Reply  Ohj.  i.  These  words  of  the  Lord  are  to  be  under- 
stood metaphorically,  and  according  to  the  likeness  of  our 
nature.  For  when  we  repent,  we  destroy  what  we  have 
made;  although  we  may  even  do  so  without  change  of  will; 
as,  when  a  man  wills  to  make  a  thing,  at  the  same  time 
intending  to  destroy  it  later.  Therefore  God  is  said  to  have 
repented,  by  way  of  comparison  with  our  mode  of  acting, 
in  so  far  as  by  the  deluge  He  destroyed  from  the  face  of  the 
earth  man  whom  He  had  made. 

Reply  Ohj.  2.  The  will  of  God,  as  it  is  the  first  and  uni- 
versal cause,  does  not  exclude  intermediate  causes  that  have 
power  to  produce  certain  effects.  Since  however  all  inter- 
mediate causes  are  inferior  in  power  to  the  first  cause,  there 
are  many  things  in  the  divine  power,  knowledge  and  will 
that  are  not  included  in  the  order  of  inferior  causes.  Thus 
in  the  case  of  the  raising  of  Lazarus,  one  who  looked  only  at 
inferior  causes  might  have  said:  Lazarus  will  not  rise  again; 
but  looking  at  the  divine  first  cause  might  have  said: 
Lazarus  will  rise  again.  And  God  wills  both:  that  is,  that 
in  the  order  of  the  inferior  cause  a  thing  shall  happen ;  but 
that  in  the  order  of  the  higher  cause  it  shall  not  happen ;  or 
He  may  will  conversely.  We  may  say,  then,  that  God 
sometimes  declares  that  a  thing  shall  happen  according  as 
it  falls  under  the  order  of  inferior  causes,  as  of  nature,  or 
merit,  which  yet  does  not  happen  as  not  being  in  the  designs 
of  the  divine  and  higher  cause.  Thus  He  foretold  to 
Ezechias:  Take  order  with  thy  house,  for  thou  shall  die,  and 
not  live  (Isa.  xxxviii.  i).  Yet  this  did  not  take  place,  since 
from  eternity  it  was  otherwise  disposed  in  the  divine  know- 
ledge and  will,  which  is  unchangeable.  Hence  Gregory  says 
{Moral,  xvi.  5):  The  sentence  of  God  changes,  hut  not  His 
counsel — that  is  to  say,  the  counsel  of  His  will.  When 
therefore  He  says,  /  also  will  repent,  His  words  must  be 


Q.  19.  Art.  8    THE  "  SUMMA  THEOLOGICA  "  276 

understood  metaphorically.  For  men  seem  to  repent,  when 
they  do  not  fulfil  what  they  have  threatened. 

Reply  Obj.  3.  It  does  not  follow  from  this  argument  that 
God  has  a  will  that  changes,  but  that  He  sometimes  wills 
that  things  should  change. 

Reply  Obj.  4.  Although  God's  willing  a  thing  is  not  by 
absolute  necessity,  yet  it  is  necessary  by  supposition,  on 
account  of  the  unchangeableness  of  the  divine  will,  as  has 
been  said  above  (A.  3). 


Eighth  Article. 

whether  the  will  of  god  imposes  necessity  on 
the  things  willed  ? 

We  proceed  thus  to  the  Eighth  Article: — 

Objection  i.  It  seems  that  the  will  of  God  imposes  neces- 
sity on  the  things  willed.  For  Augustine  says  (Enchir.  103) : 
No  one  is  saved,  except  whom  God  has  willed  to  be  saved.  He 
must  therefore  be  asked  to  will  it;  for  if  He  wills  it,  it  must 
necessarily  be. 

Obj.  2.  Further,  every  cause  that  cannot  be  hindered, 
produces  its  effect  necessarily,  because,  as  the  Philosopher 
says:  (Phys.  ii.  84)  Nature  always  works  in  the  same  way,  if 
there  is  nothing  to  hinder  it.  But  the  will  of  God  cannot  be 
hindered.  For  the  Apostle  says  (Rom.  ix.  19):  Who  re- 
sist eth  His  will  .^  Therefore  the  will  of  God  imposes  neces- 
sity on  the  things  willed. 

Obj.  3.  Further,  whatever  is  necessary  by  its  antecedent 
cause  is  necessary  absolutely;  it  is  thus  necessary  that 
animals  should  die,  being  compounded  of  contrary  elements. 
Now  things  created  by  God  are  related  to  the  divine  will 
as  to  an  antecedent  cause,  whereby  they  have  necessity. 
For  the  conditional  statement  is  true  that  if  God  wills  a 
thing,  it  comes  to  pass:  and  every  true  conditional  state- 
ment is  necessary.  It  follows  therefore  that  all  that  God 
wills  is  necessary  absolutely. 

On  the  contrary,  All  good  things  that  exist  God  wills  to  be. 
If  theriefore  His  will  imposes  necessity  on  things  willed,  it 


277  THE  WILL  OF  GOD  Q.  19.  Art.  8 

follows  that  all  good  happens  of  necessity;  and  thus  there 
is  an  end  of  free  will,  counsel,  and  all  other  such  things. 

/  answer  that,  The  divine  will  imposes  necessity  on  some 
things  willed  but  not  on  all.  The  reason  of  this  some  have 
chosen  to  assign  to  intermediate  causes,  holding  that  what 
God  produces  by  necessary  causes  is  necessary;  and  what 
He  produces  by  contingent  causes  contingent. 

This  does  not  seem  to  be  a  sufficient  explanation,  for  two 
reasons.  First,  because  the  effect  of  a  first  cause  is  con- 
tingent on  account  of  the  secondary  cause,  from  the  fact 
that  the  effect  of  the  first  cause  is  hindered  by  deficiency  in 
the  second  cause,  as  the  sun's  power  is  hindered  by  a  defect 
in  the  plant.  But  no  defect  of  a  secondary  cause  can  hinder 
God's  will  from  producing  its  effect.  Secondly,  because  if 
the  distinction  between  the  contingent  and  the  necessary 
is  to  be  referred  only  to  secondary  causes,  this  must  be 
independent  of  the  divine  intention  and  will;  which  is 
inadmissible.  It  is  better  therefore  to  say  that  this  happens 
on  account  of  the  efficacy  of  the  divine  will.  For  when  a 
cause  is  efficacious  to  act,  the  effect  follows  upon  the  cause, 
not  only  as  to  the  thing  done,  but  also  as  to  its  manner 
of  being  done  or  of  being.  Thus  from  defect  of  active 
power  in  the  seed  it  may  happen  that  a  child  is  born  unlike 
its  father  in  accidental  points,  that  belong  to  its  manner  of 
being.  Since  then  the  divine  will  is  perfectly  efficacious, 
it  follows  not  only  that  things  are  done,  which  God  wills  to 
be  done,  but  also  that  they  are  done  in  the  way  that  He  wills. 
Now  God  wills  some  things  to  be  done  necessarily,  some  con- 
tingently, to  the  right  ordering  of  things,  for  the  building  up 
of  the  universe.  Therefore  to  some  effects  He  has  attached 
necessary  causes,  that  cannot  fail;  but  to  others  defectible 
and  contingent  causes,  from  which  arise  contingent  effects. 
Hence  it  is  not  because  the  proximate  causes  are  contingent 
that  the  effects  willed  by  God  happen  contingently,  but 
because  God  has  prepared  contingent  causes  for  them,  it 
being  His  will  that  they  should  happen  contingently. 

Reply  Ohj.  i.  By  the  words  of  Augustine  we  must  under- 
stand a  necessity  in  things  willed  by  God  that  is  not  abso- 


Q.  19.  Art.  9    THE  "  SUMMA  THEOLOGICA  "  278 

lute,  but  conditional.  For  the  conditional  statement  that  if 
God  wills  a  thing  it  must  necessarily  be,  is  necessarily  true. 

Reply  Obj.  2.  From  the  very  fact  that  nothing  resists  the 
divine  will,  it  follows  that  not  only  those  things  happen 
that  God  wills  to  happen,  but  that  they  happen  necessarily 
or  contingently  according  to  His  will. 

Reply  Obj.  3.  Consequents  have  necessity  from  their 
antecedents  according  to  the  mode  of  the  antecedents. 
Hence  things  effected  by  the  divine  will  have  that  kind  of 
necessity  that  God  wills  them  to  have,  either  absolute  or 
conditional.  Not  all  things,  therefore,  are  absolute  neces- 
sities. 


Ninth  Article, 
whether  god  wills  evils  ? 

We  proceed  thus  to  the  Ninth  Article: — 

Objection  i.  It  seems  that  God  wills  evils.  For  every 
good  that  exists,  God  wills.  But  it  is  a  good  that  evil 
should  exist.  For  Augustine  says  (Enchir.  95) :  Although 
evil  in  so  far  as  it  is  evil  is  not  a  good,  yet  it  is  good  that  not 
only  good  things  should  exist,  but  also  evil  things.  Therefore 
God  wills  evil  things. 

Obj.  2.  Further,  Dionysius  says  {Div.  Norn.  iv.  23) :  Evil 
would  conduce  to  the  perfection  of  everything,  i.e.,  the  universe. 
And  Augustine  says  [Enchir.  10,  11) :  Out  of  all  things  is  built 
up  the  admirable  beauty  of  the  universe,  wherein  even  that  which 
is  called  evil,  properly  ordered  and  disposed,  commends  the 
good  the  more  evidently  in  that  good  is  more  pleasing  and 
praiseworthy  when  contrasted  with  evil.  But  God  wills  all 
that  appertains  to  the  perfection  and  beauty  of  the  universe, 
for  this  is  what  God  desires  above  all  things  in  His  creatures. 
Therefore  God  wills  evil. 

Obj.  3.  Further,  that  evil  should  exist,  and  should  not 
exist,  are  contradictory  opposites.  But  God  does  not  will 
that  evil  should  not  exist;  otherwise,  since  various  evils 
do  exist,  God's  will  would  not  always  be  fulfilled.  Therefore 
God  wills  that  evil  should  exist. 


279  THE  WILL  OF  GOD  Q.  19.  Art.  9 

On  the  contrary,  Augustine  says  (Qq.  LXXXIII.  3):  No 
wise  man  is  the  cause  of  another  man  becoming  worse.  Now 
God  surpasses  all  men  in  wisdom.  Much  less  therefore  is 
God  the  cause  of  man  becoming  worse:  and  when  He  is  said  to 
be  the  cause  of  a  thing,  He  is  said  to  will  it.  Therefore  it  is 
not  by  God's  will  that  man  becomes  worse.  Now  it  is  clear 
that  every  evil  makes  a  thing  worse.  Therefore  God  wills 
not  evil  things. 

/  answer  that.  Since  the  ratio  of  good  is  the  ratio  of  appeti- 
bihty,  as  said  before  (Q.  V.  A.  i),  and  since  evil  is  opposed 
to  good,  it  is  impossible  that  any  evil,  as  such,  should  be 
sought  for  by  the  appetite,  either  natural,  or  animal,  or  by 
the  intellectual  appetite  which  is  the  will.  Nevertheless  evil 
may  be  sought  accidentally,  so  far  as  it  accompanies  a  good, 
as  appears  in  each  of  the  appetites.  For  a  natural  agent 
intends  not  privation  or  corruption,  but  the  form  to  which  is 
annexed  the  privation  of  some  other  form,  and  the  generation 
of  one  thing,  which  implies  the  corruption  of  another.  Also 
when  a  lion  kills  a  stag,  his  object  is  food,  to  obtain  which  the 
killing  of  the  animal  is  only  the  means.  Similarly  the  forni- 
cator has  merely  pleasure  for  his  object,  and  the  deformity 
of  sin  is  only  an  accompaniment.  Now  the  evil  that  accom- 
panies one  good,  is  the  privation  of  another  good.  Never 
therefore  would  evil  be  sought  after,  not  even  accidentally, 
unless  the  good  that  accompanies  the  evil  were  more  desired 
than  the  good  of  which  the  evil  is  the  privation.  Now  God 
wills  no  good  more  than  He  wills  His  own  goodness ;  yet  He 
wills  one  good  more  than  another.  Hence  He  in  no  way  wills 
the  evil  of  sin,  which  is  the  privation  of  right  order  towards 
the  divine  good.  The  evil  of  natural  defect,  or  of  punish- 
ment, He  does  will,  by  willing  the  good  to  which  such  evils 
are  attached.  Thus  in  willing  justice  He  wills  punishment; 
and  in  willing  the  preservation  of  the  natural  order,  He  wills 
some  things  to  be  naturally  corrupted. 

Reply  Obj.  i.  Some  have  said  that  although  God  does  not 
will  evil,  yet  He  wills  that  evil  should  be  or  be  done,  because, 
although  evil  is  not  a  good,  yet  it  is  good  that  evil  should  be 
or  be  done.     This  they  said  because  things  evil  in  them- 


Q.  19.  Art.  10     THE  **  SUMMA  THEOLOGICA  "  280 

selves  are  ordered  to  some  good  end;  and  this  order  they 
thought  was  expressed  in  the  words  that  evil  should  he  or  he 
done.  This,  however,  is  not  correct;  since  evil  is  not  of 
itself  ordered  to  good,  but  accidentally.  For  it  is  beside 
the  intention  of  the  sinner,  that  any  good  should  follow  from 
his  sin;  as  it  was  beside  the  intention  of  tyrants  that  the 
patience  of  the  martyrs  should  shine  forth  from  all  their 
persecutions.  It  cannot  therefore  be  said  that  such  an 
ordering  to  good  is  implied  in  the  statement  that  it  is  a  good 
thing  that  evil  should  be  or  be  done,  since  nothing  is  judged 
of  by  that  which  appertains  to  it  accidentally,  but  by  that 
which  belongs  to  it  essentially. 

Reply  Ohj.  2.  Evil  does  not  operate  towards  the  perfec- 
tion and  beauty  of  the  universe,  except  accidentally,  as  said 
above  (ad  i).  Therefore  Dionysius  in  saying  that  evil  would 
conduce  to  the  perfection  of  the  universe,  draws  a  conclusion 
by  reduction  to  an  absurdity. 

Reply  Ohj.  3.  The  statements  that  evil  exists,  and  that  evil 
exists  not,  are  opposed  as  contradictories;  yet  the  statements 
that  anyone  wills  evil  to  exist  and  that  he  wills  it  not  to  be, 
are  not  so  opposed;  since  either  is  affirmative.  God  there- 
fore neither  wills  evil  to  be  done,  nor  wills  it  not  to  be  done, 
but  wills  to  permit  evil  to  be  done ;  and  this  is  a  good. 


Tenth  Article, 
whether  god  has  free-will  ? 

We  proceed  thus  to  the  Tenth  Article: — 

Objection  i.  It  seems  that  God  has  not  free-will.  For 
Jerome  says,  in  a  homily  on  the  prodigal  son*:  God  alone 
is  He  who  is  not  liahle  to  sin,  nor  can  he  liahle:  all  others,  as 
having  free-will,  can  he  inclined  to  either  side. 

Ohj.  2.  Further,  free-will  is  the  faculty  of  the  reason  and 
will,  by  which  good  and  evil  are  chosen.  But  God  does  not 
will  evil,  as  has  been  said  (A.  9).  Therefore  there  is  not  free- 
will in  God. 

On  the  contrary,  Ambrose  says  {De  Fide  ii.  3) :  The  Holy 

*  Ep.  146,  ad  Damas. 


28i  THE  WILL  OF  GOD  Q.  iq.Art.ii 

Spirit  divideth  unto  each  one  as  He  will,  namely,  according  to 
the  free  choice  of  the  will,  not  in  obedience  to  necessity. 

I  answer  that,  We  have  free-will  with  respect  to  what  we 
will  not  of  necessity,  nor  by  natural  instinct.  For  our  will  to 
be  happy  does  not  appertain  to  free-will,  but  to  natural  in- 
stinct. Hence  other  animals,  that  are  moved  to  act  by 
natural  instinct,  are  not  said  to  be  moved  by  free-will. 
Since  then  God  necessarily  wills  His  own  goodness,  but  other 
things  not  necessarily,  as  shown  above  (A.  3),  He  has  free 
will  with  respect  to  what  He  does  not  necessarily  will. 

Reply  Ohj.  i,  Jerome  seems  to  deny  free-will  to  God  not 
simply,  but  only  as  regards  the  inclination  to  sin. 

Reply  Ohj.  2.  Since  the  evil  of  sin  consists  in  turning 
away  from  the  divine  goodness,  by  which  God  wills  all 
things,  as  above  shown  [I.e.),  it  is  manifestly  impossible  for 
Him  to  will  the  evil  of  sin ;  yet  He  can  make  choice  of  one  of 
two  opposites,  inasmuch  as  He  can  will  a  thing  to  be,  or 
not  to  be.  In  the  same  way  we  ourselves,  without  sin,  can 
will  to  sit  down,  and  not  will  to  sit  down. 


Eleventh  Article. 

whether  the  will  of  expression  is  to  be 
distinguished  in  god  ? 

We  proceed  thus  to  the  Eleventh  Article: — 

Objection  i.  It  seems  that  the  will  of  expression  is  not  to 
be  distinguished  in  God.  For  as  the  will  of  God  is  the  cause 
of  things,  so  is  His  wisdom.  But  no  expressions  are  assigned 
to  the  divine  wisdom.  Therefore  no  expressions  ought  to 
be  assigned  to  the  divine  will. 

Obj.  2>.  Further,  every  expression  that  is  not  in  agreement 
with  the  mind  of  him  who  expresses  himself,  is  false.  If 
therefore  the  expressions  assigned  to  the  divine  will  are 
not  in  agreement  with  that  will,  they  are  false.  But  if  they 
dp  agree,  they  are  superfluous.  No  expressions  therefore 
must  be  assigned  to  the  divine  will. 

On  the  contrary,  The  will  of  God  is  one,  since  it  is  the  very 
essence  of  God.     Yet  sometimes  it  is  spoken  of  as  many, 


Q.  19.  Art.  ii     THE  "  SUMMA  THEOLOGICA  "  282 

as  in  the  words  of  Ps.  ex.  2:  Great  are  the  works  of  the  Lord, 
sought  out  according  to  all  His  wills.  Therefore,  sometimes 
the  sign  must  be  taken  for  the  will. 

/  answer  that,  Some  things  are  said  of  God  in  their  strict 
sense;  others  by  metaphor,  as  appears  from  what  has  been 
said  before  (Q.  XIII.  A.  3).  When  certain  human  passions 
are  predicated  of  the  Godhead  metaphorically,  this  is  done 
because  of  a  likeness  in  the  effect.  Hence  a  thing  that  is  in 
us  a  sign  of  some  passion,  is  signified  metaphorically  in  God 
under  the  name  of  that  passion.  Thus  with  us  it  is  usual 
for  an  angry  man  to  punish,  so  that  punishment  becomes 
an  expression  of  anger.  Therefore  punishment  itself  is 
signified  by  the  word  anger,  when  anger  is  attributed  to  God. 
In  the  same  way,  what  is  usually  with  us  an  expression  of 
will,  is  sometimes  metaphorically  called  will  in  God;  just  as 
when  anyone  lays  down  a  precept,  it  is  a  sign  that  he  wishes 
that  precept  obeyed.  Hence  a  divine  precept  is  sometimes 
called  by  metaphor  the  will  of  God,  as  in  the  words :  Thy  will 
be  done  on  earth,  as  it  is  in  heaven  (Matth.  vi.  10).  There 
is,  however,  this  difference  between  will  and  anger,  that  anger 
is  never  attributed  to  God  properly,  since  in  its  primary 
meaning  it  includes  passion;  whereas  will  is  attributed  to 
Him  properly.  Therefore  in  God  there  are  distinguished 
will  in  its  proper  sense,  and  will  as  attributed  to  Him  by 
metaphor.  Will  in  its  proper  sense  is  called  the  will  of  good 
pleasure ;  and  will  metaphorically  taken  is  the  will  of  expres- 
sion, inasmuch  as  the  sign  itself  of  will  is  called  will. 

Reply  Obj.  1.  Knowledge  is  not  the  cause  of  a  thing  being 
done,  unless  through  the  will.  For  we  do  not  put  into  act 
what  we  know,  unless  we  will  to  do  so.  Accordingly 
expression  is  not  attributed  to  knowledge,  but  to  will. 

Reply  Obj.  2.  Expressions  of  will  are  called  divine  wills, 
not  as  being  signs  that  God  wills  anything;  but  because 
what  in  us  is  the  usual  expression  of  our  will,  is  called 
the  divine  will  in  God.  Thus  punishment  is  not  ^^01 
that  there  is  anger  in  God;  but  it  is  called  anger  in^M^ 
from  the  fact  that  it  is  an  expression  of  anger  in  ourselves. 


283  THE  WILL  OF  GOD  Q.  19.  Art.  12 

Twelfth  Article. 

whether  five  expressions  of  will  are  rightly 
assigned  to  the  divine  will  ? 

We  proceed  thus  to  the  Twelfth  Article: — 

Objection  1.  It  seems  that  five  expressions  of  will — 
namely,  prohibition,  precept,  counsel,  operation,  and  permis- 
sion— are  not  rightly  assigned  to  the  divine  will.  For  the 
same  things  that  God  bids  us  do  by  His  precept  or  counsel, 
these  He  sometimes  operates  in  us,  and  the  same  things 
that  He  prohibits,  these  He  sometimes  permits.  They 
ought  not  therefore  to  be  enumerated  as  distinct. 

Obj.  2.  Further,  God  works  nothing  unless  He  will  it, 
as  the  Scripture  says  (Wis.  xi.  26).  But  the  will  of  expres- 
sion is  distinct  from  the  will  of  good  pleasure.  Therefore 
operation  ought  not  to  be  comprehended  in  the  will  of 
expression. 

Obj.  3.  Further,  operation  and  permission  appertain  to  all 
creatures  in  common,  since  God  works  in  them  all,  and 
permits  some  action  in  them  all.  But  precept,  counsel,  and 
prohibition  belong  to  rational  creatures  only.  Therefore 
they  do  not  come  rightly  under  one  division,  not  being  of 
one  order. 

Obj.  4.  Further,  evil  happens  in  more  ways  than  good, 
since  good  happens  in  one  way,  but  evil  in  all  kinds  of  ways, 
as  declared  by  the  Philosopher  [Ethic  ii.  6),  and  Dionysius 
{Div.  Norn.  iv.  22).  It  is  not  right  therefore  to  assign  one 
expression  only  in  the  case  of  evil — namely,  prohibition — 
and  two — namely,  counsel  and  precept — in  the  case  of  good. 

/  answer  that,  By  these  signs  we  name  the  expression  of 
will  by  which  we  are  accustomed  to  show  that  we  will  some- 
thing. A  man  may  show  that  he  wills  something,  either  by 
himself  or  by  means  of  another.  He  may  show  it  by  him- 
self, by  doing  something  either  directly,  or  indirectly  and 
accidentally.  He  shows  it  directly  when  he  works  in  his  own 
person;  in  that  way  the  expression  of  his  will  is  his  own 
working.  He  shows  it  indirectly,  by  not  hindering  the 
doing  of  a  thing;  for  what  removes  an  impediment  is  called 


Q.  19.  Art.  12     THE  "  SUMMA  THEOLOGICA  "  284 

an  accidental  mover.  In  this  respect  the  expression  is 
called  permission.  He  declares  his  will  by  means  of  another 
when  he  orders  another  to  perform  a  work,  either  by  in- 
sisting upon  it  as  necessary  by  precept,  and  by  prohibiting 
its  contrary;  or  by  persuasion,  which  is  a  part  of  counsel. 
Since  in  these  ways  the  will  of  man  makes  itself  known,  the 
same  live  are  sometimes  denominated  with  regard  to  the 
divine  will,  as  the  expression  of  that  will.  That  precept, 
counsel,  and  prohibition  are  called  the  will  of  God  is  clear 
from  the  words  of  Matth.  vi.  10:  Thy  will  he  done  on  earth 
as  it  is  in  heaven.  That  permission  and  operation  are  called 
the  will  of  God  is  clear  from  Augustine  (Enchir.  95),  who 
says :  Nothing  is  done,  unless  the  Almighty  wills  it  to  be  done, 
either  by  permitting  it,  or  by  actually  doing  it. 

Or  it  may  be  said  that  permission  and  operation  refer  to 
present  time,  permission  being  with  respect  to  evil,  opera- 
tion with  regard  to  good.     Whilst  as  to  future  time,  prohibi- 
tion is  in  respect  to  evil,  precept  to  good  that  is  necessary 
and  counsel  to  good  that  is  of  supererogation. 

Reply  Obj,  i.  There  is  nothing  to  prevent  anyone  declar- 
ing his  will  about  the  same  matter  in  different  ways ;  thus  we 
find  many  words  that  mean  the  same  thing.  Hence  there 
is  no  reason  why  the  same  thing  should  not  be  the  subject 
of  precept,  operation,  and  counsel;  or  of  prohibition  or 
permission. 

Reply  Obj.  2.  As  God  may  by  metaphor  be  said  to  will 
what  by  His  will,  properly  speaking.  He  wills  not;  so  He 
may  by  metaphor  be  said  to  will  what  He  does,  properly 
speaking,  will.  Hence  there  is  nothing  to  prevent  the  same 
thing  being  the  object  of  the  will  of  good  pleasure,  and  of 
the  will  of  expression.  But  operation  is  always  the  same  as 
the  will  of  good  pleasure ;  while  precept  and  counsel  are  not ; 
both  because  the  former  regards  the  present,  and  the  two 
latter  the  future;  and  because  the  former  is  of  itself  the 
effect  of  the  will;  the  latter  its  effect  as  fulfilled  by  means 
of  another. 

Reply  Obj.  3.  Rational  creatures  are  masters  of  their  own 
acts;  and  for  this  reason  certain  special  expressions  of  the 


285  THE  WILL  OF  GOD  Q.  19.  Art.  12 

divine  will  are  assigned  to  their  acts,  inasmuch  as  God 
ordains  rational  creatures  to  act  voluntarily  and  of  them 
selves.     Other  creatures  act  only  as  moved  by  the  divine 
operation;    therefore   only   operation    and   permission   are 
concerned  with  these. 

Reply  Ohj.  4.  All  evil  of  sin,  though  happening  in  many 
ways,  agrees  in  being  out  of  harmony  with  the  divine  will. 
Hence  with  regard  to  evil,  only  one  expression  is  assigned, 
that  of  prohibition.  On  the  other  hand,  good  stands  in 
various  relations  to  the  divine  goodness,  since  there  are  good 
deeds  without  which  we  cannot  attain  to  the  fruition  of  that 
goodness,  and  these  are  the  subject  of  precept;  and  there  are 
others  by  which  we  attain  to  it  more  perfectly,  and  these  are 
the  subject  of  counsel.  Or  it  may  be  said  that  counsel  is 
not  only  concerned  with  the  obtaining  of  greater  good;  but 
also  with  the  avoiding  of  lesser  evils. 


QUESTION  XX. 

GOD'S  LOVE. 

{In  Four  Articles.) 

We  next  consider  those  things  that  pertain  absolutely  to  the 
will  of  God.  In  the  appetitive  part  of  the  soul  there  are 
found  in  ourselves  both  the  passions  of  the  soul,  as  joy,  love, 
and  the  like;  and  the  habits  of  the  moral  virtues,  as  justice, 
fortitude,  and  the  like.  Hence  we  shall  first  consider  the 
love  of  God,  and  secondly  his  justice  and  mercy.  About  the 
first  there  are  four  points  of  inquiry :  (i)  Whether  love  exists 
in  God  ?  (3)  Whether  He  loves  all  things  ?  (3)  Whether 
He  loves  one  thing  more  than  another  ?  (4)  Whether  He 
loves  more  the  better  things  ? 

First  Article, 
whether  love  exists  in  god  ? 

We  proceed  thus  to  the  First  Article : — 

Objection  i.  It  seems  that  love  does  not  exist  in  God.  For 
in  God  there  are  no  passions.  Now  love  is  a  passion. 
Therefore  love  is  not  in  God. 

Obj.  2t.  Further,  love,  anger,  sorrow,  and  the  like,  are 
mutually  divided  against  one  another.  But  sorrow  and 
anger  are  not  attributed  to  God,  unless  by  metaphor. 
Therefore  neither  is  love  attributed  to  Him. 

Obj.  3.  Further,  Dionysius  says  [Biv.  Nom.  iv.) :  Love  is 
a  unitihg  and  binding  force.  But  this  cannot  take  place  in 
God,  since  He  is  simple.  Therefore  love  does  not  exist  in 
God. 

On  the  contrary,  It  is  written:  God  is  love  (i  John  iv.  16). 

/  answer  that,  We  must  needs  assert  that  in  God  there  is 

286 


28;  GOD'S  LOVE  Q.  20.  Art.  i 

love :  because  love  is  the  first  movement  of  the  will  and  of 
every  appetitive  faculty.     For  since  the  acts  of  the  will  and 
of  every  appetitive  faculty  tend  towards  good  and  evil,  as  to 
their  proper  objects :  and  since  good  is  essentially  and  especi- 
ally the  object  of  the  will  and  the  appetite,  whereas  evil  is 
only  the  object  secondarily  and  indirectly,  as  opposed  to 
good;  it  follows  that  the  acts  of  the  will  and  appetite  that 
regard  good  must  naturally  be  prior  to  those  that  regard 
evil;  thus,  for  instance,  joy  is  prior  to  sorrow,  love  to  hate: 
because  what  exists  of  itself  is  always  prior  to  that  which 
exists    through    another.     Again,    the    more    universal    is 
naturally  prior  to  what  is  less  so.     Hence  the  intellect  is 
first  directed  to  universal  truth;  and  in  the  second  place 
to  particular  and  special  truths.     Now  there  are  certain 
acts  of  the  will  and  appetite  that  regard  good  under  some 
special  condition,  as  joy  and  delight  regard  good  present 
and  possessed;  whereas  desire  and  hope  regard  good  not 
as  yet  possessed.     Love,  however,  regards  good  universally, 
whether  possessed  or  not.     Hence  love  is  naturally  the  first 
act  of  the  will  and  appetite;  for  which  reason  all  the  other 
appetitive  movements  presuppose  love,  as  their  root  and 
origin.     For  nobody  desires  anything  nor  rejoices  in  any- 
thing, except  as  a  good  that  is  loved;  nor  is  anything  an 
object  of  hate  except  as  opposed  to  the  object  of  love 
Similarly,  it  is  clear  that  sorrow,  and  other  things  like  to  it, 
must  be  referred  to  love  as  to  their  first  principle.     Hence, 
in  whomsoever  there  is  will  and  appetite,  there  must  also 
be  love:  since  if  the  first  is  wanting,  all  that  follows  is  also 
wanting.     Now  it   has  been  shown  that   will  is  in   God 
(O.    XIX.,    A.    i),    and    hence    we    must    attribute    love 
to  Him. 

Reply  Ohj.  i.  The  cognitive  faculty  does  not  move  except 
through  the  medium  of  the  appetitive:  and  just  as  in  our- 
selves the  universal  reason  moves  through  the  medium  of 
the  particular  reason,  as  stated  in  De  anima  iii.  58,  75,  so  in 
ourselves  the  intellectual  appetite,  or  the  will  as  it  is  called, 
moves  through  the  medium  of  the  sensitive  appetite. 
Hence,  in  us  the  sensitive  appetite  is  the  proximate  motive- 


Q.  20.  Art.  i     THE  "  SUMMA  THEOLOGICA  "  388 

force  of  our  bodies.  Some  bodily  change  therefore  always 
accompanies  an  act  of  the  sensitive  appetite,  and  this  change 
affects  especially  the  heart,  which,  as  the  Philosopher  says 
[De  part,  animal,  ii.  i;  iii.  4),  is  the  first  principle  of  move- 
ment in  animals.  Therefore  acts  of  the  sensitive  appetite, 
inasmuch  as  they  have  annexed  to  them  some  bodily  change, 
are  called  passions ;  whereas  acts  of  the  will  are  not  so  called. 
Love,  therefore,  and  joy  and  delight  are  passions,  in  so  far  as 
they  denote  acts  of  the  sensitive  appetite;  but  in  so  far 
as  they  denote  acts  of  the  intellective  appetite,  they  are  not 
passions.  It  is  in  this  latter  sense  that  they  are  in  God. 
Hence  the  Philosopher  says  {Ethic  vii.) :  God  rejoices  by  an 
operation  that  is  one  and  simple,  and  for  the  same  reason  He 
loves  without  passion. 

Reply  Ohj.  3.  In  the  passions  of  the  sensitive  appetite 
there  may  be  distinguished  a  certain  material  element — 
namely,  the  bodily  change — and  a  certain  formal  element, 
which  is  on  the  part  of  the  appetite.  Thus  in  anger,  as  the 
Philosopher  says  [De  anima  iii.  15,  63,  64),  the  material 
element  is  the  kindling  of  the  blood  about  the  heart;  but 
the  formal,  the  appetite  for  revenge.  Again,  as  regards  the 
formal  element  of  certain  passions  a  certain  imperfection  is 
implied,  as  in  desire,  which  is  of  the  good  we  have  not,  and 
in  sorrow,  which  is  about  the  evil  we  have.  This  applies  also 
to  anger,  which  supposes  sorrow.  Certain  other  passions, 
however,  as  love  and  joy,  imply  no  imperfection.  Since 
therefore  none  of  these  can  be  attributed  to  God  on  their 
material  side,  as  has  been  said  [ad  i) ;  neither  can  those  that 
even  on  their  formal  side  imply  imperfection  be  attributed 
to  Him;  except  metaphorically,  and  from  likeness  of  effects, 
as  already  shown  (QQ.  III.,  A.  3,  ad  3  and  XIX.,  A.  11). 
Whereas,  those  that  do  not  imply  imperfection,  such  as  love 
and  joy,  can  be  properly  predicated  of  God,  though  without 
attributing  passion  to  Him,  as  said  before  (Q.  XIX.,  A.  11). 

Reply  Ohj.  3.  An  act  of  love  always  tends  towards  two 
things;  to  the  good  that  one  wills,  and  to  the  person  for 
whom  one  wills  it :  since  to  love  a  person  is  to  wish  that  person 
good.     Hence,   inasmuch   as   we   love   ourselves,   we   wish 


289  GOD'S  LOVE  Q.  20.  Art.  2 

ourselves  good ;  and,  so  far  as  possible,  union  with  that  good. 
So  love  is  called  the  unitive  force,  even  in  God,  yet  without 
implying  composition;  for  the  good  that  He  wills  for  Him- 
self, is  no  other  than  Himself,  Who  is  good  by  His  essence, 
as  above  shown  (Q.  VI.,  AA.  i,  3).  And  by  the  fact  that 
anyone  loves  another,  he  wills  good  to  that  other.  Thus 
he  puts  the  other,  as  it  were,  in  the  place  of  himself;  and 
regards  the  good  done  to  him  as  done  to  himself.  So  far 
love  is  a  binding  force,  since  it  aggregates  another  to  our- 
selves, and  refers  his  good  to  our  own.  And  then  again 
the  divine  love  is  a  binding  force,  inasmuch  as  God  wills 
good  to  others ;  yet  it  implies  no  composition  in  God. 


Second  Article, 
whether  god  loves  all  things  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  God  does  not  love  all  things. 
For  according  to  Dionysius  {Div.  Nom.  iv.  i),  love  places 
the  lover  outside  himself,  and  causes  him  to  pass,  as  it 
were,  into  the  object  of  his  love.  But  it  is  not  admissible 
to  say  that  God  is  placed  outside  of  Himself,  and  passes  into 
other  things.  Therefore  it  is  inadmissible  to  say  that  God 
loves  things  other  than  Himself. 

Ohj.  2.  Further,  the  love  of  God  is  eternal.  But  things 
apart  from  God  are  not  from  eternity;  except  in  God. 
Therefore  God  does  not  love  anything,  except  as  it  exists 
in  Himself.  But  as  existing  in  Him,  it  is  no  other  than 
Himself.  Therefore  God  does  not  love  things  other  than 
Himself. 

Ohj.  3.  Further,  love  is  twofold— the  love,  namely,  of 
desire,  and  the  love  of  friendship.  Now  God  does  not  love 
irrational  creatures  with  the  love  of  desire,  since  He  needs  no 
creature  outside  Himself.  Nor  with  the  love  of  friendship ; 
since  there  can  be  no  friendship  with  irrational  creatures, 
as  the  Philosopher  shows  [Ethic,  viii.  2).  Therefore  God 
does  not  love  all  things. 

Ohj.  4.  Further,  it  is  written  (Ps.  v.  7) :  Thou  hatest  all 
u  19 


Q.  20.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  290 

the  workers  of  iniquity.  Now  nothing  is  at  the  same  time 
hated  and  loved.    Therefore  God  does  not  love  all  things. 

On  the  contrary,  It  is  said  (Wis.  xi.  25):  Thou  lovest  all 
things  that  are,  and  hatest  none  0/  the  things  which  Thou  hast 
made. 

I  answer  that,  God  loves  all  existing  things.  For  all 
existing  things,  in  so  far  as  they  exist,  are  good,  since  the 
existence  of  a  thing  is  itself  a  good;  and  likewise,  whatever 
perfection  it  possesses.  Now  it  has  been  shown  above 
(Q.  XIX.,  A.  4)  that  God's  will  is  the  cause  of  all  things.  It 
must  needs  be,  therefore,  that  a  thing  has  existence,  or 
any  kind  of  good,  only  inasmuch  as  it  is  willed  by  God.  To 
every  existing  thing,  then,  God  wills  some  good.  Hence, 
since  to  love  anything  is  nothing  else  than  to  will  good  to 
that  thing,  it  is  manifest  that  God  loves  everything  that 
exists.  Yet  not  as  we  love.  Because  since  our  will  is 
not  the  cause  of  the  goodness  of  things,  but  is  moved  by  it 
as  by  its  object,  our  love,  whereby  we  will  good  to  anything, 
is  not  the  cause  of  its  goodness ;  but  conversely  its  goodness, 
whether  real  or  imaginary,  calls  forth  our  love,  by  which  we 
will  that  it  should  preserve  the  good  it  has,  and  receive  be- 
sides the  good  it  has  not,  and  to  this  end  we  direct  our 
actions:  whereas  the  love  of  God  infuses  and  creates 
goodness. 

Reply  Ohj.  i.  A  lover  is  placed  outside  himself,  and  made 
to  pass  into  the  object  of  his  love,  inasmuch  as  he  wills  good 
to  the  beloved;  and  works  for  that  good  by  his  providence 
even  as  he  works  for  his  own.  Hence  Dionysius  says  {I.e.): 
On  behalf  of  the  truth  we  must  make  hold  to  say  even  this,  that  He 
Himself,  the  cause  of  all  things,  by  His  abounding  love  and 
goodness,  is  placed  outside  Himself  by  His  providence  for 
all  existing  things. 

Reply  Ohj.  2.  Although  creatures  have  not  existed  from 
eternity,  except  in  God,  yet  because  they  have  been  in  Him 
from  eternity,  God  has  known  them  eternally  in  their  proper 
natures;  and  for  that  reason  has  loved  them,  even  as  we, 
by  the  images  of  things  within  us,  know  things  existing  in 
themselves. 


291  GOD'S  LOVE  Q.  20.  Art.  3 

Reply  Ohj.  3.  Friendship  cannot  exist  except  towards 
rational  creatures,  who  are  capable  of  returning  love,  and 
communicating  one  with  another  in  the  various  works  of 
life,  and  who  may  fare  well  or  ill,  according  to  the  changes 
of  fortune  and  happiness;  even  as  to  them  is  benevolence 
properly  speaking  exercised.  But  irrational  creatures 
cannot  attain  to  loving  God,  nor  to  any  share  in  the  intel- 
lectual and  beatific  life  that  He  lives.  Strictly  speaking, 
therefore,  God  does  not  love  irrational  creatures  with  the 
love  of  friendship ;  but  as  it  were  with  the  love  of  desire,  in  so 
far  as  He  orders  them  to  rational  creatures,  and  even  to 
Himself.  Yet  this  is  not  because  He  stands  in  need  of 
them;  but  only  on  account  of  His  goodness,  and  of  the 
services  they  render  to  us.  For  we  can  desire  a  thing  for 
others  as  well  as  for  ourselves. 

Reply  Ohj.  4.  Nothing  prevents  one  and  the  same  thing 
being  loved  under  one  aspect,  while  it  is  hated  under  another. 
God  loves  sinners  in  so  far  as  they  are  existing  natures;  for 
they  have  existence,  and  have  it  from  Him.  In  so  far  as 
they  are  sinners,  they  have  not  existence  at  all,  but  fall 
short  of  it ;  and  this  in  them  is  not  from  God.  Hence  under 
this  aspect,  they  are  hated  by  Him. 

Third  Article, 
whether  god  loves  all  things  equally  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  God  loves  all  things  equally. 
For  it  is  said:  He  hath  equally  care  of  all  (Wis.  vi.  8).  But 
God's  providence  over  things  comes  from  the  love  wherewith 
He  loves  them.     Therefore  He  loves  all  things  equally. 

Ohj.  2.  Further,  the  love  of  God  is  His  essence.  But 
God's  essence  does  not  admit  of  degree;  neither  therefore 
does  His  love.  He  does  not  therefore  love  some  things 
more  than  others. 

Ohj.  3.  Further,  as  God's  love  extends  to  created  things, 
so  do  His  knowledge  and  will  extend.  But  God  is  not  said 
to  know  some  things  more  than  others;  nor  to  will  one  thing 


Q.  20.  Art.  3    THE  ''  SUMMA  THEOLOGICA  "  2(j2 

more  than  another.     Neither  therefore  does  He  love  some 
things  more  than  others. 

On  the  contrary,  Augustine  says  {Tract,  in  Joan,  ex.):  God 
loves  all  things  that  He  has  made,  and  amongst  them  rational 
creatures  more,  and  of  these  especially  those  who  are  members 
of  His  only-begotten  Son  ;  and  much  more  than  all,  His  only- 
begotten  Son  Himself 

I  answer  that.  Since  to  love  a  thing  is  to  will  it  good,  in  a 
twofold  way  anything  may  be  loved  more,  or  less.  In 
one  way  on  the  part  of  the  act  of  the  will  itself,  which  is 
more  or  less  intense.  In  this  way  God  does  not  love  some 
things  more  than  others,  because  He  loves  all  things  by  an 
act  of  the  will  that  is  one,  simple,  and  always  the  same. 
In  another  way  on  the  part  of  the  good  itself  that  a  person 
wills  for  the  beloved.  In  this  way  we  are  said  to  love  that 
one  more  than  another,  for  whom  we  will  a  greater  good, 
though  our  will  is  not  more  intense.  In  this  way  we  must 
needs  say  that  God  loves  some  things  more  than  others. 
For  since  God's  love  is  the  cause  of  goodness  in  things,  as 
has  been  said  (A.  2),  no  one  thing  would  be  better  than 
another,  if  God  did  not  will  greater  good  for  one  than  for 
another. 

Reply  Obj.  i.  God  is  said  to  have  equally  care  of  all,  not 
because  by  His  care  He  deals  out  equal  good  to  all,  but 
because  He  administers  all  things  with  a  like  wisdom  and 
goodness. 

Reply  Obj.  2.  This  argument  is  based  on  the  intensity  of 
love  on  the  part  of  the  act  of  the  will,  which  is  the  divine 
essence.  But  the  good  that  God  wills  for  His  creatures,  is  not 
the  divine  essence.  Therefore  there  is  no  reason  why  it 
may  not  vary  in  degree. 

Reply  Obj.  3.  To  understand  and  to  will  denote  the  act 
alone,  and  do  not  include  in  their  meaning  objects  from  the 
diversity  of  which  God  may  be  said  to  know  or  will  more  or 
less,  as  has  been  said  with  respect  to  God's  love. 


293  GOD'S  LOVE  Q.  20.  Art.  4 

Fourth  Article, 
whether  god  always  loves  more  the  better  things  ? 

We  proceed  thus  to  the  Fourth  Article : — 

Objection  i.  It  seems  that  God  does  not  always  love  more 
the  better  things.  For  it  is  manifest  that  Christ  is  better 
than  the  whole  human  race,  being  God  and  man.  But  God 
loved  the  human  race  more  than  He  loved  Christ ;  for  it  is 
said :  He  spared  not  His  own  Son,  hut  delivered  Him  up  for 
us  all  (Rom.  viii.  32).  Therefore  God  does  not  always  love 
more  the  better  things. 

Ohj.  2.  Further,  an  angel  is  better  than  a  man.  Hence  it 
is  said  of  man:  Thou  hast  made  him  a  little  less  than  the 
angels  (Ps.  viii.  6).  But  God  loved  men  more  than  He 
loved  the  angels,  for  it  is  said:  Nowhere  doth  He  take  hold 
of  the  angels,  but  of  the  seed  of  Abraham  He  taketh  hold  (Heb. 
ii.  16).  Therefore  God  does  not  always  love  more  the  better 
things. 

Obj.  3.  Further,  Peter  was  better  than  John,  since  he 
loved  Christ  more.  Hence  the  Lord,  knowing  this  to  be 
true,  asked  Peter,  saying :  *  Simon,  son  of  fohn,  lovest  thou 
Me  more  than  these  ?'  Yet  Christ  loved  John  more  than 
He  loved  Peter.  For  as  Augustine  says,  commenting  on 
the  words,  *  Simon,  son  of  John,  lovest  thou  Me  ?'  By  this 
very  mark  is  John  distinguished  from  the  other  disciples,  not 
that  He  loved  him  only,  but  that  He  loved  him  more  than 
the  rest.  Therefore  God  does  not  always  love  more  the 
better  things. 

Ohj.  4.  Further,  the  innocent  man  is  better  than  the  re- 
pentant, since  repentance  is,  as  Jerome  says  (Cap.  3  inlsa.), 
a  second  plank  after  shipwreck.  But  God  loves  the  penitent 
more  than  the  innocent ;  since  He  rejoices  over  him  the  more 
For  it  is  said;  /  say  to  you  that  there  shall  be  joy  in  heaven  upon 
one  sinner  that  doth  penance,  more  than  upon  ninety-7iine  just 
who  need  not  penance  (Luke  xv.  7).  Therefore  God  does  not 
always  love  more  the  better  things. 

Obj.  5.  Further,  the  just  man  who  is  foreknown  is  better 
than  the  predestined  sinner.     Now   God  loves  more  the 


Q.  20.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  294 

predestined  sinner,  since  He  wills  for  him  a  greater  good, 
life  eternal.  Therefore  God  does  not  always  love  more 
the  better  things. 

On  the  contrary,  Everything  loves  what  is  like  it,  as  appears 
from  (Ecclus.  xiii.  19) :  Every  beast  loveth  its  like.  Now  the 
better  a  thing  is,  the  more  like  is  it  to  God.  Therefore  the 
better  things  are  more  loved  by  God. 

/  answer  that,  It  must  needs  be,  according  to  what  has 
been  said  before,  that  God  loves  more  the  better  things. 
For  it  has  been  shown  (AA.  2,  3),  that  God's  loving  one  thing 
more  than  another  is  nothing  else  than  His  willing  for  that 
thing  a  greater  good:  because  God's  will  is  the  cause  of 
goodness  in  things ;  and  the  reason  why  some  things  are  better 
than  others,  is  that  God  wills  for  them  a  greater  good. 
Hence  it  follows  that  He  loves  more  the  better  things. 

Reply  Ohj.  i.  God  loves  Christ  not  only  more  than  He 
loves  the  whole  human  race,  but  more  than  He  loves  the 
entire  created  universe:  because  He  willed  for  Him  the 
greater  good  in  giving  Him  a  name  thai  is  above  all  names, 
in  so  far  as  He  was  true  God.  Nor  did  anything  of  His 
excellence  diminish  when  God  delivered  Him  up  to  death 
for  the  salvation  of  the  human  race;  rather  did  He  become 
thereby  a  glorious  conqueror:  The  government  was  placed 
upon  His  shotilder,  according  to  Isa.  ix.  6. 

Reply  Obj.  2.  God  loves  the  human  nature  assumed  by 
the  Word  of  God  in  the  person  of  Christ  more  than  He  loves 
all  the  angels;  for  that  nature  is  better,  especially  on  the 
ground  of  union  with  the  Godhead.  But  speaking  of  human 
nature  in  general,  and  comparing  it  with  the  angelic,  the 
two  are  found  equal,  in  the  order  of  grace  and  of  glory: 
since  according  to  Apoc.  xxi.  17,  the  measure  of  a  man  and 
of  an  angel  is  the  same.  Yet  so  that,  in  this  respect,  some 
angels  are  found  nobler  than  some  men,  and  some  men 
nobler  than  some  angels.  But  as  to  natural  condition  an 
angel  is  better  than  a  man.  God  therefore  did  not  assume 
human  nature  because  He  loved  man,  absolutely  speaking, 
more;  but  because  the  needs  of  man  were  greater;  just  as 
the  master  of  a  house  may  give  some  costly  delicacy  to  a

sick  servant,  that  he  does  not  give  to  his  own  son  in  sound 
health. 

Reply  Ohj.  3.  This  doubt  concerning  Peter  and  John  has 
been  solved  in  various  ways.  Augustine  {I.e.)  interprets  it 
mystically,  and  says  that  the  active  life,  signified  by  Peter, 
loves  God  more  than  the  contemplative  signified  by  John, 
because  the  former  is  more  conscious  of  the  miseries  of  this 
present  life,  and  therefore  the  more  ardently  desires  to  be 
freed  from  them,  and  depart  to  God.  God,  he  says,  loves 
more  the  contemplative  life,  since  He  preserves  it  longer. 
For  it  does  not  end,  as  the  active  life  does,  with  the  life  of 
the  body. 

Some  say  that  Peter  loved  Christ  more  in  His  members, 
and  therefore  was  loved  more  by  Christ  also,  for  which 
reason  He  gave  him  the  care  of  the  Church;  but  that 
John  loved  Christ  more  in  Himself,  and  so  was  loved  more 
by  Him;  on  which  account  Christ  commended  His  mother 
to  his  care.  Others  say  that  it  is  uncertain  which  of  them 
loved  Christ  more  with  the  love  of  charity,  and  uncertain 
also  which  of  them  God  loved  more  and  ordained  to  a 
greater  degree  of  glory  in  eternal  life.  Peter  is  said  to  have 
loved  more,  in  regard  to  a  certain  promptness  and  fervour ; 
but  John  to  have  been  more  loved,  with  respect  to  certain 
marks  of  familiarity  which  Christ  showed  to  him  rather 
than  to  others,  on  account  of  his  youth  and  purity.  While 
others  say  that  Christ  loved  Peter  more,  from  his  more 
excellent  gift  of  charity;  but  John  more,  from  his  gifts  of 
intellect.  Hence,  absolutely  speaking,  Peter  was  the  better 
and  the  more  beloved;  but,  in  a  certain  sense,  John  was  the 
better,  and  was  loved  the  more.  However,  it  may  seem 
presumptuous  to  pass  Judgment  on  these  matters;  since 
the  Lord  and  no  other,  is  the  weigher  of  spirits  (Prov. 
xvi.  2). 

Reply  Ohj.  4.  The  penitent  and  the  innocent  are  related 
as  exceeding  and  exceeded.  For  whether  innocent  or  peni- 
tent, those  are  the  better  and  the  better  loved  who  have 
most  grace.  Other  things  being  equal,  innocence  is  the 
nobler  thing  and  the  more  beloved.     God  is  said  to  rejoice 


Q.  20.  Art.  4    THE  ''  SUMMA  THEOLOGICA  ''  296 

more  over  the  penitent  than  over  the  innocent,  because  often 
penitents  rise  from  sin  more  cautious,  humble,  and  fervent. 
Hence  Gregory  commenting  on  these  words  [Horn,  xxxiv. 
in  Ev.)  says  that.  In  battle  the  general  loves  the  soldier  who 
after  flight  returns  and  bravely  pursues  the  enemy,  more  than 
him  who  has  never  fled,  but  has  never  done  a  brave  deed. 

Or  it  may  be  answered  that  gifts  of  grace,  equal  in  them- 
selves, are  more  as  conferred  on  the  penitent,  who  deserved 
punishment,  than  as  conferred  on  the  innocent,  to  whom 
no  punishment  was  due;  just  as  a  hundred  pounds  (marcce) 
are  a  greater  gift  to  a  poor  man  than  to  a  king. 

Reply  Obj.  5.  Since  God's  will  is  the  cause  of  goodness  in 
things,  the  goodness  of  one  who  is  loved  by  God  is  to  be 
reckoned  according  to  the  time  when  some  good  is  to  be 
given  to  him  by  the  divine  goodness.  According  therefore 
to  the  time,  when  there  is  to  be  given  by  the  divine  will 
to  the  predestined  sinner  a  greater  good,  the  sinner  is  the 
better;  although  according  to  some  other  time  he  is  the 
worse;  because  even  according  to  some  time  he  is  neither 
good  nor  bad. 


QUESTION  XXL 
THE  JUSTICE  AND  MERCY  OF  GOD. 

{In  Four  Articles.) 

After  considering  the  divine  love,  we  must  treat  of  God's 
justice  and  mercy.  Under  this  head  there  are  four  points  of 
inquiry:  (i)  Whether  there  is  justice  in  God  ?  (2)  Whether 
His  justice  can  be  called  truth  ?  (3)  Whether  there  is 
mercy  in  God  ?  (4)  Whether  in  every  work  of  God  there 
are  justice  and  mercy  ? 

First  Article, 
whether  there  is  justice  in  god  ? 

We  proceed  thus  to  the  First  Article : — 

Objection  i.  It  seems  that  there  is  not  justice  in  God. 
For  justice  is  divided  against  temperance.  But  temperance 
does  not  exist  in  God:  neither  therefore  does  justice. 

Obj.  2.  Further,  he  who  does  whatsoever  he  wills  and 
pleases  does  not  work  according  to  justice.  But,  as  the 
Apostle  says:  God  worketh  all  things  according  to  the  counsel 
of  his  will  (Ephes.  i.  11).  Therefore  justice  cannot  be 
attributed  to  Him. 

Obj.  3.  Further,  the  act  of  justice  is  to  pay  what  is  due. 
But  God  is  no  man's  debtor.  Therefore  justice  does  not 
belong  to  God. 

Obj.  4.  Further,  whatever  is  in  God,  is  His  essence.  But 
justice  cannot  belong  to  this.  For  Boethius  says  (De 
Hebdom.):  Good  regards  the  essence;  justice  the  act.  Therefore 
justice  does  not  belong  to  God. 

On  the  contrary,  It  is  said  (Ps.  x.  8) :  The  Lord  is  just,  and 
hath  loved  justice. 

297 


Q.  21.  Art.  i    THE  "  SUMMA  THEOLOGICA  "  298 

/  answer  that,  There  are  two  kinds  of  justice.  The  one 
consists  in  mutual  giving  and  receiving,  as  in  buying  and 
selHng,  and  other  kinds  of  intercourse  and  exchange.  This 
the  Philosopher  {Ethic,  v.  4)  calls  commutative  justice,  that 
directs  exchange  and  the  intercourse  of  business.  This  does 
not  belong  to  God,  since,  as  the  Apostle  says :  Who  hath  first 
given  to  Him,  and  recompense  shall  he  made  him  ?  (Rom. 
^i-  35)-  The  other  consists  in  distribution,  and  is  called 
distributive  justice;  whereby  a  ruler  or  a  steward  gives  to 
each  what  his  rank  deserves.  As  then  the  proper  order 
displayed  in  ruling  a  family  or  any  kind  of  multitude  evinces 
justice  of  this  kind  in  the  ruler,  so  the  order  of  the  universe, 
which  is  seen  both  in  effects  of  nature  and  in  effects  of  will, 
shows  forth  the  justice  of  God.  Hence  Dionysius  says 
{Div.  Nom.  viii.  4) :  We  must  needs  see  that  God  is  truly  just, 
in  seeing  how  He  gives  to  all  existing  things  what  is  proper  to 
the  condition  of  each;  and  preserves  the  nature  of  each  one  in 
the  order  and  with  the  powers  that  properly  belong  to  it. 

Reply  Ohj.  i.  Certain  of  the  moral  virtues  are  concerned 
with  the  passions,  as  temperance  with  concupiscence,  forti- 
tude with  fear  and  daring,  meekness  with  anger.  Such 
virtues  as  these  can  only  metaphorically  be  attributed  to 
God;  since,  as  stated  above  (Q.  XX.,  A.  i),  in  God  there  are 
no  passions ;  nor  a  sensitive  appetite,  which  is,  as  the  Philo- 
sopher says  {Ethic,  iii.  10),  the  subject  of  those  virtues.  On 
the  other  hand,  certain  moral  virtues  are  concerned  with 
works  of  giving  and  expending;  such  as  justice,  liberality, 
and  magnificence;  and  these  reside  not  in  the  sensitive 
faculty,  but  in  the  will.  Hence,  there  is  nothing  to  prevent 
our  attributing  these  virtues  to  God;  although  not  in  civil 
matters,  but  in  such  acts  as  are  not  unbecoming  to  Him. 
For,  as  the  Philosopher  says  {Ethic,  x.  8),  it  would  be  absurd 
to  praise  God  for  His  political  virtues. 

Reply  Ohj.  2.  Since  good  as  perceived  by  the  intellect  is 
the  object  of  the  will,  it  is  impossible  for  God  to  will  any- 
thing but  what  His  wisdom  approves.  This  is,  as  it  were, 
His  law  of  justice,  in  accordance  with  which  His  will  is 
right  and  just.     Hence,  what  He  does  according  to  His  will 


299    THE  JUSTICE  AND  MERCY  OF  GOD  Q.2i.Art.  i 

He  does  justly:  as  we  do  justly  what  we  do  according  to 
law.  But  whereas  law  comes  to  us  from  some  higher  power 
God  is  a  law  unto  Himself. 

Reply  Ohj.  3.  To  each  one  is  due  what  is  his  own.  Now 
that  which  is  directed  to  a  man  is  said  to  be  his  own.  Thus 
the  master  owns  the  servant,  and  not  conversely,  for  that 
is  free  which  is  its  own  cause.  In  the  word  debt,  therefore, 
is  implied  a  certain  exigence  or  necessity  of  the  thing  to 
which  it  is  directed.  Now  a  twofold  order  has  to  be  con- 
sidered in  things:  the  one,  whereby  one  created  thing  is 
directed  to  another,  as  the  parts  to  the  whole,  accident  to 
substance,  and  all  things  whatsoever  to  their  end;  the  other, 
whereby  all  created  things  are  ordered  to  God.  Thus  in  the 
divine  operations  debt  may  be  regarded  in  two  ways,  as  due 
either  to  God,  or  to  creatures,  and  in  either  way  God  pays 
what  is  due.  It  is  due  to  God  that  there  should  be  fulfilled 
in  creatures  what  His  will  and  wisdom  require,  and  what 
manifests  His  goodness.  In  this  respect  God's  justice 
regards  what  befits  Him;  inasmuch  as  He  renders  to  Him- 
self what  is  due  to  Himself.  It  is  also  due  to  a  created  thing 
that  it  should  possess  what  is  ordered  to  it;  thus  it  is  due 
to  man  to  have  hands,  and  that  other  animals  should  serve 
him.  Thus  also  God  exercises  justice,  when  He  gives  to 
each  thing  what  is  due  to  it  by  its  nature  and  condition. 
This  debt  however  is  derived  from  the  former ;  since  what  is 
due  to  each  thing  is  due  to  it  as  ordered  to  it  according  to 
the  divine  wisdom.  And  although  God  in  this  way  pays 
each  thing  its  due,  yet  He  Himself  is  not  the  debtor,  since 
He  is  not  directed  to  other  things,  but  rather  other  things 
to  Him.  Justice,  therefore,  in  God  is  sometimes  spoken 
of  as  the  fitting  accompaniment  of  His  goodness ;  sometimes 
as  the  reward  of  merit.  Anselm  touches  on  either  view 
where  he  says  (Prosolog.  10) :  When  Thou  dost  punish  the 
wicked,  it  is  just,  since  it  agrees  with  their  deserts  ;  and  when 
Thou  dost  spare  the  wicked,  it  is  also  just ;  since  it  befits  Thy 
goodness. 

Reply  Ohj.  4.  Although  justice  regards  act,  this  does  not 
prevent  its  being  the  essence  of  God;  since  even  that  which 


Q.  21.  Art.  2    THE  *'  SUMMA  THEOLOGICA  "  300 

is  of  the  essence  of  a  thing  may  be  the  principle  of  action. 
But  good  does  not  always  regard  act ;  since  a  thing  is  called 
good  not  merely  with  respect  to  act,  but  also  as  regards 
perfection  in  its  essence.  For  this  reason  it  is  said  (ibid.), 
that  the  good  is  related  to  the  just,  as  the  general  to  the 
special. 

Second  Article, 
whether  the  justice  of  god  is  truth  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  the  justice  of  God  is  not  truth. 
For  justice  resides  in  the  will;  since,  as  Anselm  says  (Dial. 
Verit.  13),  it  is  a  rectitude  of  the  will,  whereas  truth  resides 
in  the  intellect,  as  the  Philosopher  says  (Metaph.  vi.  8: 
Ethic,  vi.  2,  6).  Therefore  justice  does  not  appertain  to 
truth. 

Obj.  2.  Further,  according  to  the  Philosopher  (E'jJ/^^c.  iv.  7), 
truth  is  a  virtue  distinct  from  justice.  Truth  therefore  does 
not  appertain  to  the  idea  of  justice. 

On  the  contrary,  It  is  said  (Ps.  Ixxxiv.  11):  Mercy  and 
truth  have  met  each  other :  where  truth  stands  for  justice. 

/  answer  that,  Truth  consists  in  the  equation  of  mind 
and  thing,  as  said  above  (Q.  XVI.,  A.  i).  Now  the  mind, 
that  is  the  cause  of  the  thing,  is  related  to  it  as  its  rule 
and  measure:  whereas  the  converse  is  the  case  with  the 
mind,  that  receives  its  knowledge  from  things.  When 
therefore  things  are  the  measure  and  rule  of  the  mind, 
truth  consists  in  the  equation  of  the  mind  to  the  thing,  as 
happens  in  ourselves.  For  according  as  a  thing  is,  or  is  not, 
our  thoughts  or  our  words  about  it  are  true  or  false.  But 
when  the  mind  is  the  rule  or  measure  of  things,  truth 
consists  in  the  equation  of  the  thing  to  the  mind;  just 
as  the  work  of  an  artist  is  said  to  be  true,  when  it  is  in 
accordance  with  his  art. 

Now  as  works  of  art  are  related  to  the  art,  so  are  works  o^ 
justice  related  to  the  law  with  which  they  accord.  There- 
fore God's  justice,  which  establishes  things  in  the  order  con- 
formable to  the  rule  of  His  wisdom,  which  is  the  law  of  His 


301  THE  JUSTICE  AND  MERCY  OF  GOD    Q.  21.  Art.  3 

justice,  is  suitably  called  truth.  Thus  we  also  in  human 
affairs  speak  of  the  truth  of  justice. 

Re^ly  Ohj.  i.  Justice,  as  to  the  law  that  governs,  resides 
in  the  reason  or  intellect;  but  as  to  the  command  whereby 
our  actions  are  governed  according  to  the  law,  it  resides  in 
the  will. 

Reply  Ohj.  2.  The  truth  of  which  the  Philosopher  is  speak- 
ing in  this  passage,  is  that  virtue  whereby  a  man  shows 
himself  in  word  and  deed  such  as  he  really  is.  Thus  it 
consists  in  the  conformity  of  the  sign  with  the  thing  sig- 
nified; and  not  in  that  of  the  effect  with  its  cause  and  rule; 
as  has  been  said  regarding  the  truth  of  justice. 

Third  Article, 
whether  mercy  can  be  attributed  to  god  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  mercy  cannot  be  attributed  to 
God.  For  mercy  is  a  kind  of  sorrow,  as  Damascene  says 
{De  Fide  Orth.  ii.  14).  But  there  is  no  sorrow  in  God;  and 
therefore  there  is  no  mercy  in  Him. 

Ohj.  2.  Further,  mercy  is  a  relaxation  of  justice.  But 
God  cannot  remit  what  appertains  to  His  justice.  For  it  is 
said  (2  Tim.  ii.  13) :  //  we  helieve  not,  He  contimieth  faithful : 
He  cannot  deny  Himself.  But  He  would  deny  Himself,  as 
a  gloss  says,  if  He  should  deny  His  words.  Therefore  mercy 
is  not  becoming  to  God. 

On  the  contrary,  It  is  said  (Ps.  ex.  4) :  He  is  a  merciful  and 
gracious  Lord. 

I  answer  that,  Mercy  is  especially  to  be  attributed  to  God, 
as  seen  in  its  effect,  but  not  as  an  affection  of  passion.  In 
proof  of  which  it  must  be  considered  that  a  person  is  said 
to  be  merciful  (misericors),  as  being,  so  to  speak,  sorrowful 
at  heart  {miserum  cor)]  being  affected  with  sorrow  at  the 
misery  of  another  as  though  it  were  his  own.  Hence  it 
follows  that  he  endeavours  to  dispel  the  misery  of  this  other, 
as  if  it  were  his ;  and  this  is  the  effect  of  mercy.  To  sorrow, 
therefore,  over  the  misery  of  others  belongs  not  to  God; 


Q.  21.  Art.  3    THE  ''  SUMMA  THEOLOGICA  "  302 

but  it  does  most  properly  belong  to  Him  to  dispel  that 
misery,  whatever  be  the  defect  we  call  by  that  name. 
Now  defects  are  not  removed,  except  by  the  perfection  of 
some  kind  of  goodness :  and  the  primary  source  of  goodness 
is  God,  as  shown  above  (Q.  VI.,  A.  4).  It  must,  however,  be 
considered  that  to  bestow  perfections  appertains  not  only 
to  the  divine  goodness,  but  also  to  His  justice,  liberality,  and 
mercy;  yet  under  different  aspects.  The  communicating 
of  perfections,  absolutely  considered,  appertains  to  good- 
ness, as  shown  above  (Q.  VI.,  AA.  i,  4);  in  so  far  as  per- 
fections are  given  to  things  in  proportion,  the  bestowal  of 
them  belongs  to  justice,  as  has  been  already  said  (A.  i) ; 
in  so  far  as  God  does  not  bestow  them  for  His  own  use, 
but  only  on  account  of  His  goodness,  it  belongs  to  liberality ; 
in  so  far  as  perfections  given  to  things  by  God  expel  defects, 
it  belongs  to  mercy. 

Reply  Ohj.  i.  This  argument  is  based  on  mercy,  regarded 
as  an  affection  of  passion. 

Reply  Ohj.  2.  God  acts  mercifully,  not  indeed  by  going 
against  His  justice,  but  by  doing  something  more  than 
justice;  thus  a  man  who  pays  another  two  hundred  pieces 
of  money,  though  owing  him  only  one  hundred,  does  nothing 
against  justice,  but  acts  Uberally  or  mercifully.  The  case 
is  the  same  with  one  who  pardons  an  offence  committed 
against  him,  for  in  remitting  it  he  may  be  said  to  bestow 
a  gift.  Hence  the  Apostle  calls  remission  a  forgiving: 
Forgive  one  another,  as  Christ  has  forgiven  you  (Eph.  iv.  32). 
Hence  it  is  clear  that  mercy  does  not  destroy  justice,  but 
in  a  sense  is  the  fulness  thereof.  And  thus  it  is  said :  Mercy 
exalteth  itself  above  judgment  (Jas.  ii.  13) 


303  THE  JUSTICE  AND  MERCY  OF  GOD    Q.  21.  Art.  4 


Fourth  Article. 

whether  in  every  work  of  god  there  are  mercy 

and  justice  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  not  in  every  work  of  God  are 
mercy  and  justice.  For  some  works  of  God  are  attributed 
to  mercy,  as  the  justification  of  the  ungodly;  and  others  to 
justice,  as  the  damnation  of  the  wicked.  Hence  it  is  said: 
Judgment  without  mercy  to  him  that  hath  not  done  mercy 
(Jas.  ii.  13).  Therefore  not  in  every  work  of  God  do  mercy 
and  justice  appear. 

Ohj.  2.  Further,  the  Apostle  attributes  the  conversion  of 
the  Jews  to  justice  and  truth,  but  that  of  the  Gentiles  to 
mercy  (Rom.  xv.).  Therefore  not  in  every  work  of  God  are 
justice  and  mercy. 

Ohj.  3.  Further,  many  just  persons  are  afflicted  in  this 
world;  which  is  unjust.  Therefore  not  in  every  work  of 
God  are  justice  and  mercy. 

Ohj.  4.  Further,  it  is  the  part  of  justice  to  pay  what  is 
due,  but  of  mercy  to  relieve  misery.  Thus  both  justice  and 
mercy  presuppose  something  in  their  works:  whereas 
creation  presupposes  nothing.  Therefore  in  creation  neither 
mercy  nor  justice  is  found. 

On  the  contrary,  It  is  said  (Ps.  xxiv.  10) :  All  the  ways  of  the 
Lord  are  mercy  and  truth. 

I  answer  that,  Mercy  and  truth  are  necessarily  found  in 
all  God's  works,  if  mercy  be  taken  to  mean  the  removal  of 
any  kind  of  defect.  Not  every  defect,  however,  can  pro- 
perly be  called  a  misery;  but  only  defect  in  a  rational 
nature  whose  lot  is  to  be  happy;  for  misery  is  opposed  to 
happiness.  For  this  necessity  there  is  a  reason,  because 
since  a  debt  paid  according  to  the  divine  justice  is  one  due 
either  to  God,  or  to  some  creature,  neither  the  one  nor  the 
other  can  be  lacking  in  any  work  of  God :  because  God  can  do 
nothing  that  is  not  in  accord  with  His  wisdom  and  good- 
ness; and  it  is  in  this  sense,  as  we  have  said,  thd,t  anything 


Q.  21.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  304 

is  due  to  God.  Likewise,  whatever  is  done  by  Him  in 
created  things,  is  done  according  to  proper  order  and  pro- 
portion wherein  consists  the  idea  of  justice.  Thus  justice 
must  exist  in  all  God's  works.  Now  the  work  of  divine 
justice  always  presupposes  the  work  of  mercy ;  and  is  founded 
thereupon.  For  nothing  is  due  to  creatures,  except  for 
something  pre-existing  in  them,  or  foreknown.  Again,  if 
this  is  due  to  a  creature,  it  must  be  due  on  account  of  some- 
thing that  precedes.  And  since  we  cannot  go  on  to  infinity, 
we  must  come  to  something  that  depends  only  on  the 
goodness  of  the  divine  will — which  is  the  ultimate  end. 
We  may  say,  for  instance,  that  to  possess  hands  is  due  to 
man  on  account  of  his  rational  soul;  and  his  rational  soul 
is  due  to  him  that  he  may  be  man;  and  his  being  man  is  on 
account  of  the  divine  goodness.  So  in  every  work  of  God, 
viewed  at  its  primary  source,  there  appears  mercy.  In  all 
that  follows,  the  power  of  mercy  remains,  and  works  indeed 
with  even  greater  force;  as  the  influence  of  the  first  cause 
is  more  intense  than  that  of  second  causes.  For  this  reason 
does  God  out  of  the  abundance  of  His  goodness  bestow  upon 
creatures  what  is  due  to  them  more  bountifully  than  is 
proportionate  to  their  deserts:  since  less  would  suffice  for 
preserving  the  order  of  justice  than  what  the  divine  goodness 
confers;  because  between  creatures  and  God's  goodness  there 
can  be  no  proportion. 

Reply  Obj.  i.  Certain  works  are  attributed  to  justice,  and 
certain  others  to  mercy,  because  in  some  justice  appears 
more  forcibly  and  in  others  mercy.  Even  in  the  damnation 
of  the  reprobate  mercy  is  seen,  which,  though  it  does  not 
totally  remit,  yet  somewhat  alleviates,  in  punishing  short 
of  what  is  deserved. 

In  the  justification  of  the  ungodly  justice  is  seen,  when 
God  remits  sins  on  account  of  love,  though  He  Himself 
has  mercifully  infused  that  love.  So  we  read  of  Magdalen: 
Many  sins  are  forgiven  her,  because  she  hath  loved  much 
(Luke  vii.  47). 

Reply  Obj.  2.  God's  justice  and  mercy  appear  both  in  the 
conversion  of  the  Jews  and  of  the  Gentiles.     But  an  aspect  of 


305    THE  JUSTICE  AND  MERCY  OF  GOD    Q.  21.  Art.  4 

justice  appears  in  the  conversion  of  the  Jews  which  is  not 
seen  in  the  conversion  of  the  Gentiles;  inasmuch  as  the 
Jews  were  saved  on  account  of  the  promises  made  to  the 
fathers. 

Reply  Obj.  3.  Justice  and  mercy  appear  in  the  punish- 
ment of  the  just  in  this  world,  since  by  afflictions  lesser 
faults  are  cleansed  in  them,  and  they  are  the  more  raised  up 
from  earthly  affections  to  God.  As  to  this  Gregory  says: 
(Moral,  xxvi.  9):  The  evils  that  press  on  us  in  this  world 
force  us  to  go  to  God. 

Reply  Obj.  4.  Although  creation  presupposes  nothing  in 
the  universe ;  yet  it  does  presuppose  something  in  the  know- 
ledge of  God.  In  this  way  too  the  idea  of  justice  is  pre- 
served in  creation ;  by  the  production  of  beings  in  a  manner 
that  accords  with  the  divine  wisdom  and  goodness.  And 
the  idea  of  mercy,  also,  is  preserved  in  the  change  of  crea- 
tures from  non-existence  to  existence.

QUESTION  XXII. 

THE  PROVIDENCE  OF  GOD. 

{In  Four  Articles.) 

Having  considered  all  that  relates  to  the  will  absolutely,  we 
must  now  proceed  to  those  things  which  have  relation  to 
both  the  intellect  and  the  will,  namely  providence,  in 
respect  to  all  created  things;  predestination  and  reproba- 
tion and  all  that  is  connected  with  these  acts  in  respect 
especially  of  man  as  regards  his  eternal  salvation.  For 
in  the  science  of  morals,  after  the  moral  virtues  them- 
selves, comes  the  consideration  of  prudence,  to  which  pro- 
vidence would  seem  to  belong.  Concerning  God's  providence 
there  are  four  points  of  inquiry:  (i)  Whether  providence  is 
suitably  assigned  to  God  ?  (2)  Whether  everything  comes 
under  divine  providence  ?  (3)  Whether  divine  providence  is 
immediately  concerned  with  all  things  ?  (4  )  Whether  divine 
providence  imposes  any  necessity  upon  things  foreseen  ? 

First  Article, 
whether  providence  can  suitably  be  attributed 

TO   GOD  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  providence  is  not  becoming 
to  God.  For  providence,  according  to  TuUy  [De  Invent,  ii.), 
is  a  part  of  prudence.  But  prudence,  since,  according  to  the 
Philosopher  (Ethic,  vi.  5,  9,  18),  it  gives  good  counsel,  cannot 
belong  to  God,  Who  never  has  any  doubt  for  which  He 
should  take  counsel.  Therefore  providence  cannot  belong 
to  God. 

306 


307  THE  PROVIDENCE  OF  GOD     Q.  22.  Art.  i 

Ohj.  2.  Further,  whatever  is  in  God,  is  eternal.  But 
providence  is  not  anything  eternal,  for  it  is  concerned 
with  existing  things  that  are  not  eternal,  according  to 
Damascene  (De  Fide  Orthod.  ii.  29).  Therefore  there  is  no 
providence  in  God. 

Obj.  3.  Further,  there  is  nothing  composite  in  God.  But 
providence  seems  to  be  something  composite,  because  it 
includes  both  the  intellect  and  the  will.  Therefore  providence 
is  not  in  God. 

On  the  contrary,  It  is  said  (Wis.  xiv.  3) :  But  Thou,  Father, 
governeth  all  things  by  providence.  * 

1  answer  that,  It  is  necessary  to  attribute  providence  to 
God.  For  all  the  good  that  is  in  created  things  has  been 
created  by  God,  as  was  shown  above  (Q.  VI.,  A.  4).  In 
created  things  good  is  found  not  only  as  regards  their 
substance,  but  also  as  regards  their  order  towards  an  end 
and  especially  their  last  end,  which,  as  was  said  above,  is 
the  divine  goodness  (Q.  XXL,  A.  4).  This  good  of  order 
existing  in  things  created,  is  itself  created  by  God.  Since, 
however,  God  is  the  cause  of  things  by  His  intellect,  and 
thus  it  behoves  that  the  type  of  every  effect  should  pre- 
exist in  Him,  as  is  clear  from  what  has  gone  before  (Q.  XIX., 
A.  4),  it  is  necessary  that  the  type  of  the  order  of  things 
towards  their  end  should  pre-exist  in  the  divine  mind :  and 
the  type  of  things  ordered  towards  an  end  is,  properly 
speaking,  providence.  For  it  is  the  chief  part  of  prudence. 
to  which  two  other  parts  are  directed — namely,  remembrance 
of  the  past,  and  understanding  of  the  present ;  inasmuch  as 
from  the  remembrance  of  what  is  past  and  the  under- 
standing of  what  is  present,  we  gather  how  to  provide  for 
the  future.  Now  it  belongs  to  prudence,  according  to  the 
Philosopher  [Ethic,  vi.  12),  to  direct  other  things  towards 
an  end,  whether  in  regard  to  oneself— as,  for  instance,  a  man 
is  said  to  be  prudent,  who  orders  well  his  acts  towards  the 
end  of  life — or  in  regard  to  others  subject  to  him,  in  a  family, 
city,  or  kingdom;  in  which  sense  it  is  said  (Matth.  xxiv.  45), 
a  faithful  and  wise  servant,  whom  his  lord  hath  appointed  over 
*  Vulg.,  But  Thy  providence,  O  Father,  governeth  it. 


Q.  22.  Art.  i     THE  "  SUMMA  THEOLOGICA  "  308 

his  family.  In  this  way  prudence  or  providence  may 
suitably  be  attributed  to  God.  For  in  God  Himself  there 
can  be  nothing  ordered  towards  an  end,  since  He  is  the  last 
end.  This  type  of  the  order  in  things  towards  an  end  is 
therefore  in  God  called  providence.  Whence  Boethius  says 
{De  Consol.  iv.  6)  that  Providence  is  the  divine  type  itself, 
seated  in  the  Supreme  Ruler ;  which  disposeth  all  things  : 
which  disposition  may  refer  either  to  the  type  of  the  order 
of  things  towards  an  end,  or  to  the  type  of  the  order  of 
parts  in  the  whole. 

Reply  Obj.  i.  According  to  the  Philosopher  {Ethic,  vi.  9, 10), 
Prudence  is  what,  strictly  speaking,  commands  all  that 
'  eubulia  '  has  rightly  counselled  and  '  synesis  '  rightly  judged.*' 
Whence,  though  to  take  counsel  may  not  be  fitting  to  God» 
from  the  fact  that  counsel  is  an  inquiry  into  matters  that 
are  doubtful,  nevertheless  to  give  a  command  as  to  the 
ordering  of  things  towards  an  end,  the  right  reason  of  which 
He  possesses,  does  belong  to  God,  according  to  Ps.  cxlviii.  6 : 
He  hath  made  a  decree,  and  it  shall  not  pass  away.  In  this 
manner  both  prudence  and  providence  belong  to  God. 
Although  at  the  same  time  it  may  be  said  that  the  very 
reason  of  things  to  be  done  is  called  counsel  in  God;  not 
because  of  any  inquiry  necessitated,  but  from  the  certitude 
of  the  knowledge,  to  which  those  who  take  counsel  come 
by  inquiry.  Whence  it  is  said:  Who  worketh  all  things  ac- 
cording to  the  counsel  of  His  will  (Eph.  i.  11). 

Reply  Obj.  2.  Two  things  pertain  to  the  care  of  providence 
— namely,  the  reasmi  of  order,  which  is  called  providence 
and  disposition ;  and  the  execution  of  order,  which  is  termed 
government.  Of  these,  the  first  is  eternal,  and  the  second 
is  temporal. 

Reply  Obj.  3.  Providence  resides  in  the  intellect;  but  pre- 
supposes the  act  of  willing  the  end.  Nobody  gives  a  precept 
about  things  done  for  an  end;  unless  he  will  that  end. 
Hence  prudence  presupposes  the  moral  virtues,  by  means 
of  which  the  appetitive  faculty  is  directed  towards  good,  as 
the  Philosopher  says.     Even  if  Providence  has  to  do  with 

*  C/.  I.-II.,  Q.  LVII.,  A.  6. 


309  THE  PROVIDENCE  OF  GOD     Q.  22.  Art.  2 

the  divine  will  and  Intellect  equally,  this  would  not  affect 
the  divine  simplicity,  since  in  God  both  the  will  and  in- 
tellect are  one  and  the  same  thing,  as  we  have  said  above 
(Q.XIX.). 

Second  Article, 
whether  everything  is   subject  to  the  providence 

OF  GOD  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  everything  is  not  subject  to 
divine  providence.  For  nothing  foreseen  can  happen  by 
chance.  If  then  everything  was  foreseen  by  God,  nothing 
would  happen  by  chance.  And  thus  hazard  and  luck 
would  disappear;  which  is  against  common  opinion. 

Obj.  2.  Further,  a  wise  provider  excludes  any  defect  or 
evil,  as  far  as  he  can,  from  those  over  whom  he  has  a  care. 
But  we  see  many  evils  existing.  Either,  then,  God  cannot 
hinder  these,  and  thus  is  not  omnipotent;  or  else  He  does 
not  have  care  for  everything. 

Obj.  3.  Further,  whatever  happens  of  necessity  does  not 
require  providence  or  prudence.  Hence,  according  to  the 
Philosopher  [Ethic,  vi.  5,  9,  10,  11):  Prudence  is  the  right 
reason  of  things  contingent  concerning  which  there  is  counsel 
and  choice.  Since,  then,  many  things  happen  from  necessity, 
everything  cannot  be  subject  to  providence. 

Obj.  4.  Further,  whatsoever  is  left  to  itself  cannot  be 
subject  to  the  providence  of  a  governor.  But  men  are  left 
to  themselves  by  God,  in  accordance  with  the  words:  God 
made  man  from  the  beginning,  and  left  him  in  the  hand  of  his 
own  counsel  (Ecclus.  xv.  14).  And  particularly  in  reference 
to  the  wicked:  /  let  them  go  according  to  the  desires  of  their 
heart  (Ps.  Ixxx.  13).  Everything,  therefore,  cannot  be 
subject  to  divine  providence. 

Ohj.  5.  Further,  the  Apostle  says  (i  Cor.  ix.  9):  God  doth 
not  care  for  oxen"^ :  and  we  may  say  the  same  of  other  irra- 
tional creatures.  Thus  everything  cannot  be  under  the 
care  of  divine  providence. 

*  Vulg., — Doth  God  fake  care  for  oxen  ? 


g.  22.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  310 

On  the  contrary,  It  is  said  of  Divine  Wisdom :  She  reacheth 
from  end  to  end  mightily,  and  ordereth  all  things  sweetly 
(Wis.  viii.  i). 

/  answer  that.  Certain  persons  totally  denied  the  existence 
of  providence,  as  Democritus  and  the  Epicureans,  main- 
taining that  the  world  was  made  by  chance.  Others  taught 
that  incorruptible  things  only  were  subject  to  providence, 
and  corruptible  things  not  in  their  individual  selves,  but 
only  according  to  their  species ;  for  in  this  respect  they  are 
incorruptible.  They  are  represented  as  saying  (Job 
xxii.  14) :  The  clouds  are  His  covert ;  and  He  doth  not  consider 
our  things  ;  and  He  walketh  about  the  poles  of  heaven.  Rabbi 
Moses,  however,  excluded  men  from  the  generality  of  things 
corruptible,  on  account  of  the  excellence  of  the  intellect 
which  they  possess,  but  in  reference  to  all  else  that  suffers 
corruption  he  adhered  to  the  opinion  of  the  others. 

We  must  say,  however,  that  all  things  are  subject  to 
divine  providence,  not  only  in  general,  but  even  in  their 
own  individual  selves.  This  is  made  evident  thus.  For 
since  every  agents  acts  for  an  end,  the  ordering  of  effects 
towards  that  end  extends  as  far  as  the  causality  of  the 
first  agent  extends.  Whence  it  happens  that  in  the  effects 
of  an  agent  something  takes  place  which  has  no  reference 
towards  the  end,  because  the  effect  comes  from  a  cause 
other  than,  and  outside  the  intention  of  the  agent.  But 
the  causality  of  God,  Who  is  the  first  agent,  extends  to  all 
being,  not  only  as  to  the  constituent  principles  of  species,  but 
also  as  to  the  individualizing  principles;  not  only  of  things 
incorruptible,  but  also  of  things  corruptible.  Hence  all 
things  that  exist  in  whatsoever  manner  are  necessarily 
directed  by  God  towards  some  end;  as  the  Apostle  says: 
Those  things  that  are  of  )od  are  well  ordered*  (Rom.  xiii.  i). 
Since,  therefore,  as  the  providence  of  God  is  nothing  less 
than  the  type  of  the  order  of  things  towards  an  end,  as  we 
have  said ;  it  necessarily  follows  that  all  things,  inasmuch  as 

*  Vulg., — Those  powers  that  are,  are  ordained  of  God: — Qucs 
autem  sunt,  a  Deo  ordinatcB  sunt.  St.  Thomas  often  quotes  this 
passage,  and  invariably  reads:  Qucb  a  Deo  sunt,  ordinata  sunt. 


311  THE  PROVIDENCE  OF  GOD     Q.  22.  Art.  2 

they  participate  existence,  must  likewise  be  subject  to 
divine  providence.  It  has  also  been  shown  (Q.  XIV., 
AA.  6,  11)  that  God  knows  all  things,  both  universal  and 
particular.  And  since  His  knowledge  may  be  compared 
to  the  things  themselves,  as  the  knowledge  of  art  to  the 
objects  of  art,  all  things  must  of  necessity  come  under  His 
ordering;  as  all  things  wrought  by  art  are  subject  to  the 
ordering  of  that  art. 

Reply  Ohj.  i.  There  is  a  difference  between  universal 
and  particular  causes.  A  thing  can  escape  the  order  of  a 
particular  cause;  but  not  the  order  of  a  universal  cause. 
For  nothing  escapes  the  order  of  a  particular  cause,  except 
through  the  intervention  and  hindrance  of  some  other 
particular  cause;  as,  for  instance,  wood  may  be  prevented 
from  burning,  by  the  action  of  water.  Since,  then,  all 
particular  causes  are  included  under  the  universal  cause,  it 
could  not  be  that  any  effect  should  take  place  outside  the 
range  of  that  universal  cause.  So  far  then  as  an  effect  escapes 
the  order  of  a  particular  cause,  it  is  said  to  be  casual  or  for- 
tuitous in  respect  to  that  cause;  but  if  we  regard  the  universal 
cause,  outside  whose  range  no  effect  can  happen,  it  is  said 
to  be  foreseen.  Thus,  for  instance,  the  meeting  of  two 
servants,  although  to  them  it  appears  a  chance  circumstance, 
has  been  fully  foreseen  by  their  master,  who  has  purposely 
sent  them  to  meet  at  the  one  place,  in  such  a  way  that  the 
one  knows  not  about  the  other. 

Reply  Ohj.  2.  It  is  otherwise  with  one  who  has  care  of  a 
particular  thing,  and  one  whose  providence  is  universal, 
because  a  particular  provider  excludes  all  defects  from 
what  is  subject  to  his  care  as  far  as  he  can;  whereas,  one 
who  provides  universally  allows  some  little  defect  to  remain, 
lest  the  good  of  the  whole  should  be  hindered.  Hence, 
corruption  and  defects  in  natural  things  are  said  to  be 
contrary  to  some  particular  nature;  yet  they  are  in  keeping 
with  the  plan  of  universal  nature;  inasmuch  as  the  defect 
in  one  thing  yields  to  the  good  of  another,  or  even  to  the 
universal  good:  for  the  corruption  of  one  is  the  generation 
of  another,  and  through  this  it  is  that  a  species  is  kept  in 


Q.  22.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  312 

existence.  Since  God,  then,  provides  universally  for  all 
being,  it  belongs  to  His  providence  to  permit  certain  defects 
in  particular  effects,  that  the  perfect  good  of  the  universe  may 
not  be  hindered,  for  if  all  evil  were  prevented,  much  good 
would  be  absent  from  the  universe.  A  lion  would  cease  to 
live,  if  there  were  no  slaying  of  animals ;  and  there  would  be 
no  patience  of  martyrs  if  there  were  no  tyrannical  persecu- 
tion. Thus  Augustine  says  {Enchir.  ii.) :  Almighty  God  would 
in  no  wise  permit  evil  to  exist  in  His  works,  unless  He  were 
so  almighty  and  so  good  as  to  produce  good  even  from  evil. 
It  would  appear  that  it  was  on  account  of  these  two  argu- 
ments to  which  we  have  just  replied,  that  some  were  per- 
suaded to  consider  corruptible  things — e.g.,  casual  and  evil 
things — as  removed  from  the  care  of  divine  providence. 

Reply  Ohj.  3.  Man  is  not  the  author  of  nature;  but  he  uses 
natural  things  in  applying  art  and  virtue  to  his  own  use. 
Hence  human  providence  does  not  reach  to  that  which  takes 
place  in  nature  from  necessity;  but  divine  providence 
extends  thus  far,  since  God  is  the  author  of  nature.  Ap- 
parently it  was  this  argument  that  moved  those  who  with- 
drew the  course  of  nature  from  the  care  of  divine  provi- 
dence, attributing  it  rather  to  the  necessity  of  matter,  as 
Democritus,  and  others  of  the  ancients. 

Reply  Ohj.  4.  When  it  is  said  that  God  left  man  to  himself, 
this  does  not  mean  that  man  is  exempt  from  divine  provi- 
dence ;  but  merely  that  he  has  not  a  prefixed  operating  force 
determined  to  only  the  one  effect ;  as  in  the  case  of  natural 
things,  which  are  only  acted  upon  as  though  directed  by 
another  towards  an  end ;  and  do  not  act  of  themselves,  as  if 
they  directed  themselves  towards  an  end,  like  rational 
creatures,  through  the  possession  of  free  will,  by  which 
these  are  able  to  take  counsel  and  make  a  choice.  Hence 
it  is  significantly  said :  In  the  hand  of  his  own  counsel.  But 
since  the  very  act  of  free  will  is  traced  to  God  as  to  a  cause, 
it  necessarily  follows  that  everything  happening  from  the 
exercise  of  free  will  must  be  subject  to  divine  providence. 
For  human  providence  is  included  under  the  providence  of 
God,  as  a  particular  under  a  universal  cause.     God,  however. 


313  THE  PROVIDENCE  OF  GOD     Q.  22.  Art.  3 

extends  His  providence  over  the  just  in  a  certain  more 
excellent  way  than  over  the  wicked ;  inasmuch  as  He  prevents 
anything  happening  which  would  impede  their  final  salva- 
tion. For  to  them  that  love  God,  all  things  work  together  unto 
good  (Rom.  viii.  28).  But  from  the  fact  that  He  does  not 
restrain  the  wicked  from  the  evil  of  sin,  He  is  said  to  abandon 
them :  not  that  He  altogether  withdraws  His  providence  from 
them;  otherwise  they  would  return  to  nothing,  if  they  were 
not  preserved  in  existence  by  His  providence.  This  was  the 
reason  that  had  weight  with  Tully,  who  withdrew  from 
the  care  of  divine  providence  human  affairs  concerning 
which  we  take  counsel. 

Reply  Ohj.  5.  Since  a  rational  creature  has,  through  its 
free  will,  control  over  its  actions,  as  was  said  above  (Q.  XIX., 
A.  10),  it  is  subject  to  divine  providence  in  an  especial 
manner,  so  that  something  is  imputed  to  it  as  a  fault,  or 
as  a  merit;  and  there  is  given  it  accordingly  something  by 
way  of  punishment  or  reward.  In  this  way  the  Apostle 
withdraws  oxen  from  the  care  of  God:  not,  however,  that 
individual  irrational  creatures  escape  the  care  of  divine 
providence ;  as  was  the  opinion  of  the  Rabbi  Moses. 

Third  Article. 

whether  god  has  immediate  providence  over 
everything  ? 

We  proceed  thus  to  the  Third  Article: — 

Objection  i.  It  seems  that  God  has  not  immediate  pro- 
vidence over  all  things.  For  whatever  is  contained  in  the 
notion  of  dignity,  must  be  attributed  to  God.  But  it  belongs 
to  the  dignity  of  a  king,  that  he  should  have  ministers  ; 
through  whose  mediation  he  provides  for  his  subjects. 
Therefore  much  less  has  God  HimseH  immediate  providence 
over  all  things. 

Ohj.  2.  Further,  it  belongs  to  providence  to  order  all 
things  to  an  end.  Now  the  end  of  everything  is  its  perfec- 
tion and  its  good.  But  it  appertains  to  every  cause  to 
direct  its  effect  to  good;  wherefore  every  active  cause  is  a 


Q.  22.ART.  3     THE  "  SUMMA  THEOLOGICA  "  314 

cause  of  the  effect  of  providence.  If  therefore  God  were  to 
have  immediate  providence  over  all  things,  all  secondary 
causes  would  be  withdrawn. 

Ohj.  3.  Further,  Augustine  says  {Enchir.  17)  that,  It  is 
better  to  be  ignorant  of  some  things  than  to  know  them,  for 
example,  vile  things:  and  the  Philosopher  says  the  same 
{Metaph.  xii.  51).  But  whatever  is  better  must  be  assigned 
to  God.  Therefore  He  has  not  immediate  providence  over 
bad  and  vile  things. 

On  the  contrary,  It  is  said  (Job  xxxiv.  13) :  What  other  hath 
He  appointed  over  the  earth  ?  or  whom  hath  He  set  over  the 
world  which  He  made  ?  On  which  passage  Gregory  says 
(Moral,  xxiv.  20):  Himself  He  ruleth  the  world  which  He 
Himself  hath  made. 

I  answer  that,  Two  things  belong  to  providence — namely, 
the  type  of  the  order  of  things  foreordained  towards  an  end ; 
and  the  execution  of  this  order,  which  is  called  government. 
As  regards  the  first  of  these,  God  has  immediate  providence 
over  everything,  because  he  has  in  His  intellect  the  types 
of  everything,  even  the  smallest;  and  whatsoever  causes 
He  assigns  to  certain  effects.  He  gives  them  the  power  to 
produce  those  effects.  Whence  it  must  be  that  He  has 
beforehand  the  type  of  those  effects  in  His  mind.  As  to 
the  second,  there  are  certain  intermediaries  of  God's  provi- 
dence; for  He  governs  things  inferior  by  superior,  not  on 
account  of  any  defect  in  His  power,  but  by  reason  of  the 
abundance  of  His  goodness ;  so  that  the  dignity  of  causality 
is  imparted  even  to  creatures.  Thus  Plato's  opinion,  as 
narrated  by  Gregory  of  Nyssa  {De  provid.  viii.  3),  is  ex- 
ploded. He  taught  a  threefold  providence.  First,  one  which 
belongs  to  the  supreme  Deity,  Who  first  and  foremost  has 
provision  over  spiritual  things,  and  thus  over  the  whole 
world  as  regards  genus,  species,  and  universal  causes.  The 
second  providence,  which  is  over  the  individuals  of  all  that 
can  be  generated  and  corrupted,  he  attributed  to  the  divi- 
nities who  circulate  in  the  heavens ;  that  is,  certain  separate 
substances,  which  move  corporeal  things  in  a  circular 
direction.     The  third  providence,  over  human  affairs,  he 


315  THE  PROVIDENCE  OF  GOD      Q.  22.  Art.  4 

assigned  to  demons,  whom  the  Platonic  philosophers  placed 
between  us  and  the  gods,  as  Augustine  tells  us  (De  Civ. 
Dei  ix.  I,  2 :  viii.  14). 

Reply  Ohj.  i.  It  pertains  to  a  king's  dignity  to  have 
ministers  who  execute  his  providence.  But  the  fact  that 
he  has  not  the  plan  of  those  things  which  are  done  by  them 
arises  from  a  deficiency  in  himself.  For  every  operative 
science  is  the  more  perfect,  the  more  it  considers  the  par- 
ticular things  with  which  its  action  is  concerned. 

Reply  Ohj.  2.  God's  immediate  provision  over  every- 
thing does  not  exclude  the  action  of  secondary  causes; 
which  are  the  executors  of  His  order,  as  was  said  above 
(Q.  XIX.,  AA.  5,  8). 

Reply  Ohj.  3.  It  is  better  for  us  not  to  know  low  and  vile 
things,  because  by  them  we  are  impeded  in  our  knowledge  of 
what  is  better  and  higher;  for  we  cannot  understand  many 
things  simultaneously;  and  because  the  thought  of  evil 
sometimes  perverts  the  will  towards  evil.  This  does  not 
hold  with  God,  Who  sees  everything  simultaneously  at  one 
glance,  and  whose  will  cannot  turn  in  the  direction  of  evil. 

Fourth  Article. 

whether  providence  imposes  any  necessity 
on  things  foreseen  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Ohjection  i.  It  seems  that  divine  providence  imposes 
necessity  upon  things  foreseen.  For  every  effect  that 
ha».  a  per  se  cause,  either  present  or  past,  which  it  neces- 
slfily  follows,  happens  from  necessity;  as  the  Philosopher 
proves  (Metaph.  vi.  7).  But  the  providence  of  God,  since 
it  is  eternal,  pre-exists;  and  the  effect  flows  from  it  of 
necessity,  for  divine  providence  cannot  be  frustrated. 
Therefore  divine  providence  imposes  a  necessity  upon  things 
foreseen. 

Ohj.  2.  Further,  every  provider  makes  his  work  as  stable 
as  he  can,  lest  it  should  fail.  But  God  is  most  powerful. 
Therefore  He  assigns  the  stability  of  necessity  to  things 
provided. 


Q.  22.  Art.  4    THE  "  SUMMA  THEOLOGICA  "  316 

Ohj.  3.  Further,  Boethius  says  {De  Consol.  iv.  6):  Fate 
from  the  immutable  source  of  providence  hinds  together  human 
acts  and  fortunes  by  the  indissoluble  connexion  of  causes. 
It  seems  therefore  that  providence  imposes  necessity  upon 
things  foreseen. 

On  the  contrary,  Dionysius  says  that  (Div.  Norn.  iv.  23) 
to  corrupt  nature  is  not  the  work  of  providence.  But  it  is  in 
the  nature  of  some  things  to  be  contingent.  Divine  pro- 
vidence does  not  therefore  impose  any  necessity  upon  things 
so  as  to  destroy  their  contingency. 

/  answer  that,  Divine  providence  imposes  necessity  upon 
some  things;  not  upon  all,  as  some  formerly  believed.  For 
to  providence  it  belongs  to  order  things  towards  an  end. 
Now  after  the  divine  goodness,  which  is  an  extrinsic  end  to 
all  things,  the  principal  good  in  things  themselves  is  the 
perfection  of  the  universe;  which  would  not  be,  were  not  all 
grades  of  being  found  in  things.  Whence  it  pertains  to 
divine  providence  to  produce  every  grade  of  being.  And 
thus  it  has  prepared  for  some  things  necessary  causes,  so 
that  they  happen  of  necessity ;  for  others  contingent  causes, 
that  they  may  happen  by  contingency,  according  to  the 
nature  of  their  proximate  causes. 

Reply  Obj.  i.  The  effect  of  divine  providence  is  not  only 
that  things  should  happen  somehow;  but  that  they  should 
happen  either  by  necessity  or  by  contingency.  Therefore 
whatsoever  divine  providence  ordains  to  happen  infallibly 
and  of  necessity  happens  infallibly  and  of  necessity;  and 
that  happens  from  contingency,  which  the  plan  of  divine 
providence  conceives  to  happen  from  contingency.         ^ 

Reply  Obj.  2.  The  order  of  divine  providence  is  unchange- 
able and  certain,  so  far  as  all  things  foreseen  happen  as  they  % 
have  been  foreseen,  whether  from  necessity  or  from  (con- 
tingency. 

Reply  Obj.  3.  That  indissolubility  and  unchangeableness 
of  which  Boethius  speaks,  pertain  to  the  certainty  of  provi- 
dence, which  fails  not  to  produce  its  effect,  and  that  in 
the  way  foreseen;  but  they  do  not  pertain  to  the  necessity 
of  the  effects.     We  must  remember  that  properly  speaking 


317  THE  PROVIDENCE  OF  GOD     Q.  22.  Art.  4 

necessary  and  contingent  are  consequent  upon  being,  as 
such.  Hence  the  mode  both  of  necessity  and  of  contingency 
falls  under  the  foresight  of  God,  who  provides  universally 
for  all  being;  not  under  the  foresight  of  causes  that  provide 
only  for  some  particular  order  of  things. 


QUESTION  XXIII. 

OF  PREDESTINATION. 

{In  Eight  Articles.) 

After  the  consideration  of  divine  providence,  we  must 
treat  of  predestination  and  the  book  of  life.  Concerning  per- 
destination  there  are  eight  points  of  inquiry:  (i)  Whether 
predestination  is  suitably  attributed  to  God  ?  (2)  What 
is  predestination,  and  whether  it  places  anything  in  the 
predestined  ?  (3)  Whether  to  God  belongs  the  reprobation 
of  some  men  ?  (4)  On  the  comparison  of  predestination 
to  election;  whether,  that  is  to  say,  the  predestined  are 
chosen  ?  (5)  Whether  merits  are  the  cause  or  reason  of 
predestination,  or  reprobation,  or  election  ?  (6)  Of  the 
certainty  of  predestination;  whether  the  predestined  will 
infalUbly  be  saved  ?  (7)  Whether  the  number  of  the  pre- 
destined is  certain  ?  (8)  Whether  predestination  can  be 
furthered  by  the  prayers  of  the  saints  ? 

First  Article, 
whether  men  are  predestined  by  god  ? 

We  proceed  thus  to  the  First  Article: — 

Objection  i.  It  seems  that  men  are  not  predestined  by  God^ 
for  Damascene  says  {De  Fide  Orthod.  ii.  30) :  It  must  be  borne 
in  mind  that  God  foreknows  but  does  not  predetermine  every- 
thing, since  He  foreknows  all  that  is  in  us,  but  does  not 
predetermine  it  all.  But  human  merit  and  demerit  are  in 
us,  forasmuch  as  we  are  the  masters  of  our  own  acts  by 
free-will.  All  that  pertains  therefore  to  merit  or  demerit 
is  not  predestined  by  God;  and  thus  man's  predestination 
is  done  away.

319  PREDESTINATION  Q.  23.  Art.  i 

Ohj.  2.  Further,  all  creatures  are  directed  to  their  end 
by  divine  providence,  as  was  said  above  (Q.  XXIL,  AA.  i,  2). 
But  other  creatures  are  not  said  to  be  predestined  by  God. 
Therefore  neither  are  men. 

Obj.  3.  l^Slrther,  the  angels  are  capable  of  beatitude,  as 
well  as  men.  But  predestination  is  not  suitable  to  angels, 
since  in  them  there  never  was  any  unhappiness  (miseria) ; 
for  predestination,  as  Augustine  says  (De  prcedest.  sand.  17), 
is  the  purpose  to  take  pity  (miserendi)^.  Therefore  men 
are  not  predestined. 

Obj.  4.  Further,  the  benefits  God  confers  upon  men  are 
revealed  by  the  Holy  Ghost  to  holy  men  according  to  the 
saying  of  the  Apostle  (i  Cor.  ii.  12):  Now  we  have  received 
not  the  spirit  of  this  world,  but  the  Spirit  that  is  of  God:  that 
we  may  know  the  things  that  are  given  us  from  God.  Therefore 
if  man  were  predestined  by  God,  since  predestination  is  a 
benefit  from  God,  his  predestination  would  be  made  known 
to  each  predestined;  which  is  clearly  false. 

On  the  contrary,  It  is  written  (Rom.  viii.  30) :  Whom  He 
predestined,  them  He  also  called. 

I  answer  that.  It  is  fitting  that  God  should  predestine 
men.  For  all  things  are  subject  to  His  providence,  as  was 
shown  above  (Q.  XXIL,  A.  2).  Now  it  belongs  to  provi- 
dence to  direct  things  towards  their  end,  as  was  also  said 
(Q.  XXIL,  AA.  I,  2).  The  end  towards  which  created  things 
are  directed  by  God  is  twofold;  one  which  exceeds  all 
proportion  and  faculty  of  created  nature;  and  this  end  is 
Hfe  eternal,  that  consists  in  seeing  God  which  is  above  the 
nature  of  every  creature,  as  shown  above  (Q.  XIL,  4).  The 
other  end,  however,  is  proportionate  to  created  nature, 
to  which  end  created  being  can  attain  according  to  the 
power  of  its  nature.  Now  if  a  thing  cannot  attain  to  some- 
thing by  the  power  of  its  nature,  it  must  be  directed  thereto  .^ 
by  another ;  thus,  an  arrow  is  directed  by  the  archer  towards 
a  mark.  Hence,  properly  speaking,  a  rational  creature,* 
capable  of  eternal  life,  is  led  towards  it,  directed,  as  it  were, 
by  God.     The  reason  of  that  direction  pre-exists  in  God; 

*  SeeQ.  XXII.  A.  3. 


Q.  23.  Art.  i    THE  ''  SUMMA  THEOLOGICA  "  320 

as  in  Him  is  the  15^6  of  the  order  of  all  things  towards  an 
end,  which  we  proved  above  to  be  providence.  Now  the 
type  in  the  mind  of  the  doer  of  something  to  be  done,  is  a 
kind  of  pre-existence  in  him  of  the  thing  to  be  dope.  Hengg 
the  type  of  the  aforesaid  direction  of  a  ratitMlfcfSBB^ 
towards  the  end  of  life  eternal  is  called  predestination. 
For  to  destine,  is  to  direct  or  send.  Thus  it  is  clear 
that  predestination,  as  regards  its  objects,  is  a  part  of 
providence. 

Reply  Obj.  i.  Damascene  calls  predestination  an  impo- 
sition of  necessity,  after  the  manner  of  natural  things 
which  are  predetermined  towards  one  end.  This  is  clear 
from  his  adding:  He  does  not  will  malice,  nor  does  He 
compel  virtue.  Whence  predestination  is  not  excluded 
by  him. 

Reply  Obj.  2.  Irrational  creatures  are  not  capable  of  that 
end  which  exceeds  the  faculty  of  human  nature.  Whence 
they  cannot  be  properly  said  to  be  predestined;  although 
improperly  the  term  is  used  in  respect  of  any  other  end. 

Reply  Obj.  3.  Predestination  applies  to  angels,  just  as 
it  does  to  men,  although  they  have  never  been  unhappy. 
For  movement  does  not  take  its  species  from  the  term 
wherefrom,  but  from  the  term  whereto.  Because  it  matters 
nothing,  in  respect  of  the  notion  of  making  white,  whether 
he  who  is  made  white  was  before  black,  yellow,  or  red. 
Likewise  it  matters  nothing  in  respect  of  the  notion  of 
predestination  whether  one  is  predestined  to  life  eternal 
from  the  state  of  misery  or  not.  Although  it  may  be  said 
that  every  conferring  of  good  above  that  which  is  due  per- 
tains to  mercy;  as  was  shown  previously  (Q.  XXL,  AA.  3,  4). 

Reply  Obj.  4.  Even  if  by  a  special  privilege  their  pre- 
destination were  revealed  to  some,  it  is  not  fitting  that  it 
should  be  revealed  to  everyone ;  because,  if  so,  those  who  were 
not  predestined  would  despair;  and  security  would  beget 
negligence  in  the  predestined. 


321  PREDESTINATION  Q.  23.  Art.  2 


Second  Article. 

whether  predestination  places  anything  in  the 

predestined  ? 

We  proceed  thus  to  the  Second  Article: — 

Objection  i.  It  seems  that  predestination  does  place 
something  in  the  predestined.  For  every  action  of  itself 
causes  passion.  If  therefore  predestination  is  action  in 
God,  predestination  must  be  passion  in  the  predestined. 

Obj.  2.  Further,  Origen  says  on  the  text,  He  who  was  pre- 
destined, etc.  (Rom.  i.  4) :  Predestination  is  of  one  who  is  not; 
destination,  of  one  who  is.  And  Augustine  says  (De  Prced. 
Sand.):  What  is  predestination  but  the  destination  of  one  who 
is  ?  Therefore  predestination  is  only  of  one  who  actually 
exists ;  and  it  thus  places  something  in  the  predestined. 

Obj.  3.  Further,  preparation  is  something  in  the  thing 
prepared.  But  predestination  is  the  preparation  of  God's 
benefits,  as  Augustine  says  {De  Freed.  Sand.  ii.  14).  There- 
fore predestination  is  something  in  the  predestined. 

Obj.  4.  Further,  nothing  temporal  enters  into  the  defini- 
tion of  eternity.  But  grace,  which  is  something  temporal, 
is  found  in  the  definition  of  predestination.  For  predestina- 
tion is  the  preparation  of  grace  in  the  present ;  and  of  glory 
in  the  future.  Therefore  predestination  is  not  anything 
eternal.  So  it  must  needs  be  that  it  is  in  the  predestined, 
and  not  in  God ;  for  whatever  is  in  Him  is  eternal. 

On  the  contrary,  Augustine  says  {ibid.)  that  predestination 
is  the  foreknowledge  of  God's  benefits.  But  foreknowledge  is 
not  in  the  things  foreknown,  but  in  the  person  who  fore- 
knows them.  Therefore,  predestination  is  in  the  one  who 
predestines,  and  not  in  the  predestined. 

/  answer  that.  Predestination  is  not  anything  in  the  pre- 
destined; but  only  in  the  person  who  predestines.  We  have 
said  above  that  predestination  is  a  part  of  providence. 
Now  providence  is  not  anything  in  the  things  provided 
for ;  but  is  a  type  in  the  mind  of  the  provider,  as  was  proved 
above  (Q.  XXII.,  A.  i.).     But  thie  execution  of  providence* 


Q.  23.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  322 

which  is  called  government,  is  in  a  passive  way  in  the  thing 
governed,  and  in  an  active  way  in  the  governor.  Whence 
it  is  clear  that  predestination  is  a  kind  of  type  of  the  order- 
ing of  some  persons  towards  eternal  salvation,  existing  in 
the  divine  mind.  The  execution,  however,  of  this  order  is 
in  a  passive  way  in  the  predestined,  but  actively  in  God. 
The  execution  of  predestination  is  the  calhng  and  magnifi- 
cation; according  to  the  Apostle  (Rom.  viii.  30):  Whom  He 
predestinated,  them  He  also  called;  and  whom  He  called,  them 
He  also  magnified  (Vulg.,  justified). 

Reply  Ohj.  i.  Actions  passing  out  to  external  matter 
imply  of  themselves  passion — for  example,  the  actions  of 
warming  and  cutting;  but  not  so  actions  remaining  in  the 
agent,  as  understanding  and  wilHng,  as  said  above 
(QQ.  XIV.,  A.  2. ;  XVIIL,  A.  3,  ad  i).  Predestination  is  an 
action  of  this  latter  class.  Wherefore,  it  does  not  put  any- 
thing in  the  predestined.  But  its  execution,  which  passes 
out  to  external  things,  has  an  effect  in  them. 

Reply  Ohj,  2.  Destination  sometimes  denotes  a  real 
mission  of  someone  to  a  given  end;  thus,  destination  can 
only  be  said  of  someone  actually  existing.  It  is  taken, 
however,  in  another  sense  for  a  mission  which  a  person 
conceives  in  the  mind;  and  in  this  manner  we  are  said 
to  destine  a  thing  which  we  firmly  propose  in  our  mind. 
In  this  latter  way  it  is  said  that  Eleazar  determined  not  to 
do  any  unlawful  things  for  the  love  of  life  (2  Mac.  vi.  20). 
Thus  destination  can  be  of  a  thing  which  does  not  exist. 
Predestination,  however,  by  reason  of  the  antecedent 
nature  it  implies,  can  be  attributed  to  a  thing  which  does 
not  actually  exist ;  in  whatsoever  way  destination  is  accepted. 

Reply  Ohj,  3.  Preparation  is  twofold:  of  the  patient  in 
respect  to  passion  and  this  is  in  the  thing  prepared  and  of 
the  agent,  to  action,  and  this  is  in  the  agent.  Such  a  pre- 
paration is  predestination,  as  an  agent  by  intellect  is  said  to 
prepare  itself  to  act,  accordingly  as  it  preconceives  the 
idea  of  what  is  to  be  done.  Thus,  God  from  all  eternity 
prepared  by  predestination,  conceiving  the  idea  of  the 
order  of  some  towards  salvation. 


323  PREDESTINATION  Q.  23.  Art.  3 

Reply  Ohj,  4.  Grace  does  not  come  into  the  definition  of 
predestination,  as  something  belonging  to  its  essence,  but 
inasmuch  as  predestination  implies  a  relation  to  grace, 
as  of  cause  to  effect,  and  of  act  to  its  object.  Whence 
it  does  not  follow  that  predestination  is  anything  temporal. 


Third  Article, 
whether  god  reprobates  any  man  ? 

We  proceed  thus  to  the  third  Article: — 

Objection  i.  It  seems  that  God  reprobates  no  man.  For 
nobody  reprobates  what  he  loves.  But  God  loves  every 
man,  according  to  (Wis.  xi.  25) :  Thou  lovest  all  things  that 
are,  and  Thou  hatest  none  of  the  things  Thou  hast  made. 
Therefore  God  reprobates  no  man. 

Ohj.  2.  Further,  if  God  reprobates  any  man,  it  would  be 
necessary  for  reprobation  to  have  the  same  relation  to  the 
reprobate  as  predestination  has  to  the  predestined.  But 
predestination  is  the  cause  of  the  salvation  of  the  pre- 
destined. Therefore  reprobation  will  Hkewise  be  the  cause 
of  the  loss  of  the  reprobate.  But  this  is  false.  For  it  is 
said  (Osee  xiii.  9) :  Destruction  is  thy  own,  0  Israel;  Thy  help 
is  only  in  Me.     God  does  not,  then,  reprobate  any  man. 

Ohj.  3.  Further,  to  no  one  ought  anything  to  be  imputed 
which  he  cannot  avoid.  But  if  God  reprobates  anyone,  that 
one  must  perish.  For  it  is  said  (Eccl.  vii.  14) :  Consider  the 
works  of  God,  that  no  man  can  correct  whom  He  hath  despised. 
Therefore  it  could  not  be  imputed  to  any  man,  were  he  to 
perish.  But  this  is  false.  Therefore  God  does  not  reprobate 
anyone. 

On  the  contrary,  It  is  said  (Malach.  i.  2,  3):  /  have  loved 
Jacoh,  hut  have  hated  Esau. 

I  answer  that,  God  does  reprobate  some.  For  it  was  said 
above  (A.  i)  that  predestination  is  a  part  of  providence.  To 
providence,  however,  it  belongs  to  permit  certain  defects 
in  those  things  which  are  subject  to  providence,  as  was 
said  above  (Q.  XXII. ,  A.  2).  Thus,  as  men  are  ordained 
to  eternal  life  through  the  providence  of  God,  it  likewise  is 


Q.  23.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  324 

part  of  that  providence  to  permit  some  to  fall  away  from 
that  end ;  this  is  called  reprobation.  Thus,  as  predestination 
is  a  part  of  providence,  in  regard  to  those  ordained  to  eternal 
salvation,  so  reprobation  is  a  part  of  providence  in  regard 
to  those  who  turn  aside  from  that  end.  Hence  reprobation 
imphes  not  only  foreknowledge,  but  also  something  more, 
as  does  providence,  as  was  said  above  (Q.  XXII.,  A.  i). 
Therefore,  as  predestination  includes  the  will  to  confer  grace 
and  glory ;  so  also  reprobation  includes  the  will  to  permit 
a  person  to  fall  into  sin,  and  to  impose  the  punishment  of 
damnation  on  account  of  that  sin. 

Reply  Ohj.  i.  God  loves  all  men  and  all  creatures,  inas- 
much as  He  wishes  them  all  some  good;  but  He  does  not 
wish  every  good  to  them  all.  So  far,  therefore,  as  He  does 
not  wish  this  particular  good — namely,  eternal  life — He  is 
said  to  hate  or  reprobate  them. 

Reply  Ohj.  2.  Reprobation  differs  in  its  causaHty  from 
predestination.  This  latter  is  the  cause  both  of  what  is 
expected  in  the  future  life  by  the  predestined — namely* 
glory — and  of  what  is  received  in  this  life — namely,  grace. 
Reprobation,  however,  is  not  the  cause  of  what  is  in  the 
present — namely,  sin;  but  it  is  the  cause  of  abandonment 
by  God.  It  is  the  cause,  however,  of  what  is  assigned  in  the 
future — namely,  eternal  punishment.  But  guilt  proceeds 
from  the  free-will  of  the  person  who  is  reprobated  and 
deserted  by  grace.  In  this  way  the  word  of  the  prophet 
is  true  —namely.  Destruction  is  thy  own,  0  Israel. 

Reply  Ohj.  3.  Reprobation  by  God  does  not  take  any- 
thing away  from  the  power  of  the  person  reprobated. 
Hence,  when  it  is  said  that  the  reprobated  cannot  obtain 
grace,  this  must  not  be  understood  as  implying  absolute 
^  impossibility;  but  only  conditional  impossibility:  as  was 
said  above  (Q.  XIX.,  A.  3),  that  the  predestined  must  neces- 
sarily be  saved;  yet  by  a  conditional  necessity,  which  does 
not  do  away  with  the  liberty  of  choice.  Whence,  although 
anyone  reprobated  by  God  cannot  acquire  grace,  nevertheless 
that  he  falls  into  this  or  that  particular  sin  comes  from  the  use 
bf  his  frefe-will.     Hence  it  is  rightly  imputed  to  him  as  guilt. 


325  PREDESTINATION  Q.  23.  Art.  4 

Fourth  Article, 
whether  the  predestined  are  chosen  by  god  ?* 

We  proceed  thus  to  the  Fourth  Article: — 

Objection  i.  It  seems  that  the  predestined  are  not  chosen 
by  God.  For  Dionysius  says  (Div.  Norn.  iv.  i)  that  as  the 
corporeal  sun  sends  his  rays  upon  all  without  selection, 
so  does  God  His  goodness.  But  the  goodness  of  God  is 
communicated  to  some  in  an  especial  manner  through  a 
participation  of  grace  and  glory.  Therefore  God  without 
any  selection  communicates  His  grace  and  glory;  and  this 
belongs  to  predestination. 

Obj.  2.  Further,  election  is  of  things  that  exist.  But  pre- 
destination from  all  eternity  is  also  of  things  which  do  not 
exist.     Therefore,  some  are  predestined  without  election. 

Obj.  3.  Further,  election  implies  some  discrimination. 
Now  God  wills  all  men  to  be  saved  (i  Tim.  ii.  4).  Therefore, 
predestination  which  ordains  men  towards  eternal  salvation, 
is  without  election. 

On  the  contrary,  It  is  said  (Ephes.  i.  4):  He  chose  us  in 
Him  before  the  foundation  of  the  world. 

I  answer  that,  Predestination  presupposes  election  in  the 
order  of  reason;  and  election  presupposes  love.  The  reason 
of  this  is  that  predestination,  as  stated  above  (A.  i),  is  a 
part  of  providence.  Now  providence,  as  also  prudence,  is 
the  plan  existing  in  the  intellect  directing  the  ordering 
of  some  things  towards  an  end;  as  was  proved  above 
(Q.  XXII.,  A.  2).  But  nothing  is  directed  towards  an 
end  unless  the  will  for  that  end  already  exists.  Whence 
the  predestination  of  some  to  eternal  salvation  presupposes, 
in  the  order  of  reason,  that  God  wills  their  salvation;  and 
to  this  belong  both  election  and  love: — ^love,  inasmuch  as 
He  wills  them  this  particular  good  of  eternal  salvation; 
since  to  love  is  to  wish  well  to  anyone,  as  stated  above 
(Q.  XX.,  AA.  2,  3.) :— election,  inasmuch  as  He  wills  this  good 
to  some  in  preference  to  others;  since  He  reprobates  some, 
as  stated  above  (A.  3.)     Election  and  love,  however,  are 

*  Eligantur. 


Q.  23.  Art.  5    THE  "  SUMMA  THEOLOGICA  "  326 

differently  ordered  in  God,  and  in  ourselves:  because  in 
us  the  will  in  loving  does  not  cause  good,  but  we  are  incited 
to  love  by  the  good  which  already  exists;  and  therefore  we 
choose  someone  to  love,  and  so  election  in  us  precedes  love. 
In  God,  however,  it  is  the  reverse.  For  His  will,  by  which 
in  loving  He  wishes  good  to  someone,  is  the  cause  of  that 
good  possessed  by  some  in  preference  to  others.  Thus  it 
is  clear  that  love  precedes  election  in  the  order  of  reason, 
and  election  precedes  predestination.  Whence  all  the 
predestinate  are  objects  of  election  and  love. 

Reply  Ohj.  i.  If  the  communication  of  the  divine  good- 
ness in  general  be  considered,  God  communicates  His  good- 
ness without  election;  inasmuch  as  there  is  nothing  which 
does  not  in  some  way  share  in  His  goodness,  as  we  said 
above  (Q.  VL,  A.  4.)  But  if  we  consider  the  communication 
of  this  or  that  particular  good.  He  does  not  allot  it  without 
election;  since  He  gives  certain  goods  to  some  men,  which 
He  does  not  give  to  others.  Thus  in  the  conferring  of  grace 
and  glory  election  is  implied. 

Reply  Ohj.  2.  When  the  will  of  the  person  choosing  is 
incited  to  make  a  choice  by  the  good  already  pre-existing 
in  the  object  chosen,  the  choice  must  needs  be  of  those 
things  which  already  exist,  as  happens  in  our  choice.  In 
God  it  is  otherwise ;  as  was  said  above  (Q.  XX.,  A.  2.) .  Thus, 
as  Augustine  says  [De  Verb.  Ap.  Serm.  11) :  Those  are  chosen 
by  God,  who  do  not  exist;  yet  He  does  not  err  in  His  choice. 

Reply  Ohj,  3.  God  wills  all  men  to  be  saved  by  His  ante- 
cedent will,  which  is  to  will  not  simply  but  relatively;  and 
not  by  His  consequent  will,  which  is  to  will  simply. 

Fifth  Article. 

whether  the  foreknowledge  of  merits  is  the 
cause  of  predestination? 

We  proceed  thus  to  the  Fifth  Article: — 

Objection  i.  It  seems  that  foreknowledge  of  merits  is  the 
cause  of  predestination.  For  the  Apostle  says  (Rom.  viii.  29) : 
Whom  He  foreknew,  He  also  predestinated.     Again  a  gloss  of 


327  PREDESTINATION  Q.  23.  Art.  5 

Ambrose  on  Rom.  ix.  15:  /  will  have  mercy  upon  whom  I 
will  have  mercy  says :  /  will  give  mercy  to  him  who,  I  foresee, 
will  turn  to  Me  with  his  whole  heart.  Therefore  it  seems 
the  foreknowledge  of  merits  is  the  case  of  predestination. 

Ohj.  2.  Further,  Divine  predestination  includes  the  divine 
will,  which  by  no  means  can  be  irrational ;  since  predestina- 
tioa  is  the  purpose  to  have  mercy,  as  Augustine  says  {De 
Prazd.  Sand.  ii.  17).  But  there  can  be  no  other  reason  for 
predestination  than  the  foreknowledge  of  merits.  There- 
fore ix  must  be  the  cause  or  reason  of  predestination. 

Ohj.  3.  Further,  There  is  no  injustice  in  God  (Rom.  ix.  14). 
Now  it  would  seem  unjust  that  unequal  things  be  given  to 
equals.  But  all  men  are  equal  as  regards  both  nature  and 
original  sin ;  and  inequality  in  them  arises  from  the  merits 
or  demerits  of  their  actions.  Therefore  God  does  not  prepare 
unequal  things  for  men  by  predestinating  and  reprobating, 
unless  through  the  foreknowledge  of  their  merits  and 
demerits, 

On  the  contrary,  The  Apostle  says  (Tit.  iii.  5) :  Not  by  the 
works  of  justice  which  we  have  done,  hut  according  to  His 
mercy  He  saved  us.  But  as  He  saved  us,  so  He  predestined 
that  we  should  be  saved.  Therefore,  foreknowledge  of 
merits  is  not  the  cause  or  reason  of  predestination. 

I  answer  that.  Since  predestination  includes  will,  as  was 
said  above  (A.  4),  the  reason  of  predestination  must  be 
sought  for  in  the  same  way  as  was  the  reason  of  the  will 
of  God.  Now  it  was  shown  above  (Q.  XIX.,  A.  5.),  that 
we  cannot  assign  any  cause  of  the  divine  will  on  the  part 
of  the  act  of  willing ;  but  a  reason  can  be  found  on  the  part 
of  the  things  willed;  inasmuch  as  God  wills  one  thing  on 
account  of  something  else.  Wherefore  nobody  has  been 
so  insane  as  to  say  that  merit  is  the  cause  of  divine  predes- 
tination as  regards  the  act  of  the  predestinator.  But  this 
is  the  question,  whether,  as  regards  the  effect,  predestination 
has  any  cause;  or  what  comes  to  the  same  thing,  whether 
God  pre-ordained  that  He  would  give  the  effect  of  predes- 
tination to  anyone  on  account  of  any  merits. 

Accordingly  there  were  some  who  held  that  the  effect 


Q.  23.  Art.  5    THE  "  SUMMA  THEOLOGICA  "  328 

of  predestination  was  pre-ordained  for  some  on  account  of 
pre-existing  merits  in  a  former  life.  This  was  the  opinion 
of  Origen,  who  thought  that  the  souls  of  men  were  created 
in  the  beginning,  and  according  to  the  diversity  of  their 
works  different  states  were  assigned  to  them  in  this  world 
when  united  to  the  body.  The  Apostle,  however,  rebuts  this 
opinion  where  he  says  (Rom.  ix.  11,  12) :  For  when  they 
were  not  yet  born,  nor  had  done  any  good  or  evil,  .  .  .  noi  of 
works,  hilt  of  Him  that  calleth,  it  was  said  to  her:  The  dder 
shall  serve  the  younger. 

Others  said  that  pre-existing  merits  in  this  life  are  the 
reason  and  cause  of  the  effect  of  predestination.  For  the 
Pelagians  taught  that  the  beginning  of  doing  well  came 
from  us;  and  the  consummation  from  God:  so  that  it 
came  about  that  the  effect  of  predestination  was  granted 
to  one,  and  not  to  another,  because  the  one  made  a  beginning 
by  preparing,  whereas  the  other  did  not.  But  against  this 
we  have  the  saying  of  the  Apostle  (2  Cor.  iii.  5),  that 
ive  are  not  sufficient  to  think  anything  of  ourselves  as  of  our- 
selves. Now  no  principle  of  action  can  be  imagined  previous 
to  the  act  of  thinking.  Wherefore  it  cannot  be  Said  that 
anything  begun  in  us  can  be  the  reason  of  the  1  effect  of 
predestination.  j 

And  so  others  said  that  merits  following  the  effect  of  pre- 
destination are  the  reason  of  predestination;  giving  us  to 
understand  that  God  gives  grace  to  a  person,  and  pre-ordains 
that  He  will  give  it,  because  He  knows  beforehaiid  that  He 
will  make  good  use  of  that  grace,  as  if  a  king  were  to  give  a 
horse  to  a  soldier  because  he  knows  he  will  make  good  use  of 
it.  But  these  seem  to  have  drawn  a  distinction  between  that 
which  flows  from  grace,  and  that  which  flows  f rpm  free  will, 
as  if  the  same  thing  cannot  come  from  both.  It  is,  however, 
manifest  that  what  is  of  grace  is  the  effect  of  predestination ; 
and  this  cannot  be  considered  as  the  reason  of  predestination, 
since  it  is  contained  in  the  notion  of  predestination.  There- 
fore, if  anything  else  in  us  be  the  reason  of  predestination,  it 
will  be  outside  the  effect  of  predestination.  Now  there  is  no 
distinction  between  what  flows  from  free  will,  and  what  is 


329  PREDESTINATION  Q.  23.  Art.  5 

of  predestination;  as  there  is  no  distinction  between  what 
flows  from  a  secondary  cause  and  from  a  first  cause.  For  the 
providence  of  God  produces  effects  through  the  operation  of 
secondary  causes,  as  was  above  shown  (Q.  XXIL,  A.  3). 
Wherefore,  that  which  flows  from  free-will  is  also  of  pre- 
destination. We  must  say,  therefore,  that  the  effect  of 
predestination  may  be  considered  in  a  twofold  light — in  one 
way,  in  particular;  and  thus  there  is  no  reason  why  one 
effect  of  predestination  should  not  be  the  reason  or  cause  of 
another;  a  subsequent  effect  being  the  reason  of  a  previous 
effect,  as  its  final  cause;  and  the  previous  effect  being  the 
reason  of  the  subsequent  as  its  meritorious  cause,  which  is 
reduced  to  the  disposition  of  the  matter.  Thus  we  might 
say  that  God  preordained  to  give  glory  on  account  of  merit, 
and  that  He  preordained  to  give  grace  to  merit  glory. 
In  another  way,  the  effect  of  predestination  may  be  con- 
sidered in  general.  Thus,  it  is  impossible  that  the  whole 
of  the  effect  of  predestination  in  general  should  have  any 
cause  as  coming  from  us;  because  whatsoever  is  in  man 
disposing  him  towards  salvation,  is  all  included  under  the 
effect  of  predestination;  even  the  preparation  for  grace. 
For  neither  does  this  happen  otherwise  than  by  divine  help, 
according  to  the  prophet  Jeremias  (Lam.  v.  21) :  Convert  us, 
0  Lord,  to  Thee,  and  we  shall  he  converted.  Yet  predestina- 
tion has  in  this  way,  in  regard  to  its  effect,  the  goodness  of 
God  for  its  reason;  towards  which  the  whole  effect  of  pre- 
destination is  directed  as  to  an  end;  and  from  which  it 
proceeds,  as  from  its  first  moving  principle. 

Reply  Obj.  i.  The  use  of  grace  foreknown  by  God  is 
not  the  cause  of  conferring  grace,  except  after  the  manner 
of  a  final  cause;  as  was  explained  above. 

Reply  Obj.  2.  Predestination  has   its   foundation  in  the 
goodness  of  God  as  regards  its  effects  in  general.     Con- 
sidered in  its  particular  effects,  however,  one  effect  is  the^ 
reason  of  another;  as  already  stated. 

Reply  Obj.  3.  The  reason  for  the  predestination  of  some, 
and  reprobation  of  others,  must  be  sought  for  in  the  goodness 
of  God.     Thus  He  is  said  to  have  made  all  things  through 


Q.  23.  Art.  5    THE  ''  SUMMA  THEOLOGICA  "  330 

His  goodness,  so  that  the  divine  goodness  might  be  repre- 
sented in  things.  Now  it  is  necessary  that  God's  goodness, 
which  in  itself  is  one  and  undivided,  should  be  manifested  in 
many  ways  in  His  creation ;  because  creatures  in  themselves 
cannot  attain  to  the  simplicity  of  God.  Thus  it  is  that  for 
the  completion  of  the  universe  there  are  required  different 
grades  of  being;  some  of  which  hold  a  high  and  some  a  low 
place  iti  the  universe.  That  this  multiformity  of  grades  may 
be  preserved  in  things,  God  allows  some  evils,  lest  many  good 
things  should  never  happen,  as  was  said  above  (Q.  XXII. 
A.  2).  Let  us  then  consider  the  whole  of  the  human  race, 
as  we  consider  the  whole  universe.  God  wills  to  manifest 
His  goodness  in  men;  in  respect  to  those  whom  He  pre- 
destines, by  means  of  His  mercy,  in  sparing  them;  and  in 
respect  of  others,  whom  he  reprobates,  by  means  of  His 
justice,  in  punishing  them.  This  is  the  reason  why  God 
elects  some  and  rejects  others.  To  this  the  Apostle  refers, 
saying  (Rom.  ix.  22,  23) :  What  if  God,  willing  to  show  His 
wrath  [that  is,  the  vengeance  of  His  justice],  and  to  make 
His  power  known,  endured  [that  is,  permitted]  with  much 
patience  vessels  of  wrath,  fitted  for  destruction;  that  He  might 
show  the  riches  of  His  glory  on  the  vessels  of  mercy,  which  He 
hath  prepared  unto  glory  (Rom.  ix.  22,  23) :  and  (2  Tim.  ii.  20) : 
But  in  a  great  house  there  are  not  only  vessels  of  gold  and  silver; 
but  also  of  wood  and  of  earth;  and  some,  indeed,  unto  honour, 
hut  some  unto  dishonour.  Yet  why  He  chooses  some  for 
glory,  and  reprobates  others,  has  no  reason,  except  the  divine 
will.  Whence  Augustine  says  {Tract,  xxvi.  in  Joan.):  Why 
He  draws  one,  and  another  He  draws  not,  seek  not  to  judge,  if 
thou  dost  not  wish  to  err.  Thus  too,  in  the  things  of  nature, 
a  reason  can  be  assigned,  since  primary  matter  is  altogether 
uniform,  why  one  part  of  it  was  fashioned  by  God  from  the 
beginning  under  the  form  of  fire,  another  under  the  form  of 
earth,  that  there  might  be  a  diversity  of  species  in  things 
of  nature.  Yet  why  this  particular  part  of  matter  is  under 
this  particular  form,  and  that  under  another,  depends  upon 
the  simple  will  of  God ;  as  from  the  simple  will  of  the  artificer 
it  depends  that  this  stone  is  in  this  part  of  the  wall,  and  that 


331  PREDESTINATION  Q.  23.  Art.  6 

in  another;  although  the  plan  requires  that  some  stones 
should  be  in  this  place,  and  some  in  that  place.  Neither  on 
this  account  can  there  be  said  to  be  injustice  in  God,  if  He 
prepares  unequal  lots  for  not  unequal  things.  This  would 
be  altogether  contrary  to  the  notion  of  justice,  if  the  effect  of 
predestination  were  granted  as  a  debt,  and  not  gratuitously. 
In  things  which  are  given  gratuitously  a  person  can  give 
more  or  less,  just  as  he  pleases  (provided  he  deprives  nobody 
of  his  due),  without  any  infringement  of  justice.  This  is 
what  the  master  of  the  house  said:  Take  what  is  thine,  and 
go  thy  way.  Is  it  not  lawful  for  me  to  do  what  I  will  ?  (Matth. 
XX.  14,  15). 

Sixth  Article, 
whether  predestination  is  certain  ? 

We  proceed  thus  to  the  Sixth  Article: — 

Objection  i.  It  seems  that  predestination  is  not  certain. 
Because  on  the  words  Hold  fast  that  which  thou  hast,  that 
no  one  take  thy  crown  (Apoc.  iii.  11),  Augustine  says  {De  Corr. 
et  Grat.  15):  Another  will  not  receive,  unless  this  one  were  to 
lose  it.  Hence  the  crown  which  is  the  effect  of  predestina- 
tion can  be  both  acquired  and  lost.  Therefore  predestina- 
tion cannot  be  certain. 

Obj.  2.  Further,  granted  what  is  possible,  nothing  impos- 
sible follows.  But  it  is  possible  that  one  predestined — 
e.g.,  Peter — may  sin  and  then  be  killed.  But  if  this  were 
so,  it  would  follow  that  the  effect  of  predestination  would 
be  thwarted.  This,  then,  is  not  impossible.  Therefore  pre- 
destination is  not  certain. 

Obj.  3.  Further,  whatever  God  could  do  in  the  past.  He  can 
do  now.  But  He  could  have  not  predestined  whom  He  hath 
predestined.  Therefore  now  He  is  able  not  to  predestine 
him.     Therefore  predestination  is  not  certain. 

On  the  contrary,  A  gloss  on  Rom.  viii.  29:  Whom  He  fore- 
knew, He  also  predestinated,  says :  Predestination  is  the  fore- 
knowledge and  preparation  of  the  benefits  of  God,  by  which 
whosoever  are  freed  will  most  certainly  be  freed. 

I  answer  thct,  Predestination  most  certainly  and  infallibly 


Q.  23.  Art.  6    THE  "  SUMMA  THEOLOGICA  "  332 

takes  effect;  yet  it  does  not  impose  any  necessity,  so  that, 
namely,  its  effect  should  take  place  from  necessity.  For  it  was 
said  above  (A.  i),  that  predestination  is  a  part  of  providence. 
But  not  all  things  subject  to  providence  are  necessary;  some 
things  happening  from  contingency,  according  to  the  nature 
of  the  proximate  causes,  which  divine  providence  has 
ordained  for  such  effects.  Yet  the  order  of  providence  is 
infalUble,  as  was  shown  above  (Q.  XXIL,  A.  4).  So  also 
the  order  of  predestination  is  certain;  yet  free  will  is  not 
destroyed;  whence  the  effect  of  predestination  has  its 
contingency.  Moreover  all  that  has  been  said  about  the 
divine  knowledge  and  will  (QQ.  XIV.,  A.  13,  and XIX.,  A.  4) 
must  also  be  taken  into  consideration;  since  they  do  not 
destroy  contingency  in  things,  although  they  themselves 
are  most  certain  and  infallible. 

Reply  Ohj.  i.  The  crown  may  be  said  to  belong  to  a  person 
in  two  ways;  first,  by  God's  predestination,  and  thus  no 
one  loses  his  crown:  secondly,  by  the  merit  of  grace;  for 
what  we  merit,  in  a  certain  way  is  ours ;  and  thus  anyone  may 
lose  his  crown  by  mortal  sin.  Another  person  receives  that 
crown  thus  lost,  inasmuch  as  he  takes  the  former's  place. 
For  God  does  not  permit  some  to  fall,  without  raising  others; 
according  to  Job  xxxiv.  24:  He  shall  break  in  pieces  many  and 
innumerable,  and  make  others  to  stand  in  their  stead.  Thus 
men  are  substituted  in  the  place  of  the  fallen  angels  ;  and 
the  Gentiles  in  that  of  the  Jews.  He  who  is  substituted 
for  another  in  the  state  of  grace,  also  receives  the  crown  of 
the  fallen  in  that  in  eternal  life  he  will  rejoice  at  the  good 
the  other  has  done,  in  which  life  he  will  rejoice  at  all  good 
whether  done  by  himself  or  by  others. 

Reply  Obj.  2.  Although  it  is  possible  for  one  who  is  pre- 
V  destinated  considered  in  himself  to  die  in  mortal  sin;  yet 
it  is  not  possible,  supposed,  as  in  fact  it  is  supposed,  that  he 
is  predestinated.     Whence  it  does  not  follow  that  predesti- 
nation can  fall  short  of  its  effect. 

Reply  Obj.  3.  Since  predestination  includes  the  divine  will 
as  stated  above  (A.  4):  and  the  fact  that  God  wills  any 
created  thing  is  necessary  on  the  supposition  that  He  so  wills. 


333  PREDESTINATION  Q.  23.  Art.  7 

on  account  of  the  immutability  of  the  divine  will,  but  is  not 
necessary  absolutely;  so  the  same  must  be  said  of  pre- 
destination. Wherefore  one  ought  not  to  say  that  God  is 
able  not  to  predestinate  one  whom  He  has  predestinated, 
taking  it  in  a  composite  sense,  though,  absolutely  speaking, 
God  can  predestinate  or  not.  But  in  this  way  the  certainty 
of  predestination  is  not  destroyed. 

Seventh  Article, 
whether  the  number  of  the  predestined  is  certain  ? 

We  proceed  thus  to  the  Seventh  Article  : — 

Objection  i.  It  seems  that  the  number  of  the  predestined 
is  not  certain.  For  a  number  to  which  an  addition  can  be 
made  is  not  certain.  But  there  can  be  an  addition  to  the 
number  of  the  predestined  as  it  seems;  for  it  is  written 
(Deut.  i.  11) :  The  Lord  God  adds  to  this  number  many  thou- 
sands, and  a  gloss  adds,  fixed  by  God,  who  knows  those  who 
belong  to  Him.  Therefore  the  number  of  the  predestined 
is  not  certain. 

Obj.  2.  Further,  no  reason  can  be  assigned  why  God 
preordains  to  salvation  one  number  of  men  more  than 
another.  But  nothing  is  arranged  by  God  without  a  reason. 
Therefore  the  number  to  be  saved  preordained  by  God 
cannot  be  certain. 

Obj.  3.  Further,  the  operations  of  God  are  more  perfect 
than  those  of  nature.  But  in  the  works  of  nature,  good  is 
found  in  the  majority  of  things;  defect  and  evil  in  the 
minority.  If,  then,  the  number  of  the  saved  were  fixed  by 
God  at  a  certain  figure,  there  would  be  more  saved  than 
lost.  Yet  the  contrary  follows  from  Matth.  vii.  13,  14: 
For  wide  is  the  gate,  and  broad  the  way  that  leadeth  to  destruc- 
tion, and  many  there  are  who  go  in  thereat.  How  narrow  is 
the  gate,  and  strait  is  the  way  that  leadeth  to  life;  and  few  there 
are  that  find  it !  Therefore  the  number  of  those  preordained 
by  God  to  be  saved  is  not  certain. 

On  the  contrary,  Augustine  says  {De  Corr.  et  Grat.  13): 
The  number  of  the  predestined  is  certain,  and  can  neither  be 
increased  nor  dimi^iished. 


Q.  23.  Art.  7    THE  "  SUMMA  THEOLOGICA  "  334 

I  answer  that,  The  number  of  the  predestined  is  certain. 
Some  have  said  that  it  was  formally,  but  not  materially 
certain ;  as  if  we  were  to  say  that  it  was  certain  that  a  hun- 
dred or  a  thousand  would  be  saved;  not  however  these  or 
those    individuals.     But    this    destroys    the    certainty    of 
predestination;  of  which  we  spoke  above  (A.  6).     Therefore 
we  must  say  that  to  God  the  number  of  the  predestined 
is  certain,  not  only  formally,  but  also  materially.     It  must, 
however,  be  observed  that  the  number  of  the  predestined 
is  said  to  be  certain  to  God,  not  only  by  reason  of  His  know- 
ledge, because,  that  is  to  say.  He  knows  how  many  will  be 
saved  (for  in  this  way  the  number  of  drops  of  rain  and  the 
sands  of  the  sea  are  certain  to  God) ;  but  by  reason  of  His 
deliberate    choice    and    determination.     For    the    further 
evidence  of  which  we  must  remember  that  every  agent 
intends  to  make  something  finite,  as  is  clear  from  what  has 
been  said  above  when  we  treated  of  the  infinite  (Q.  VH., 
AA.  2,  3).     Now  whosoever  intends  some  definite  measure 
in  his  effect  thinks  out  some  definite  number  in  the  essential 
parts,   which  are  by  their  very  nature  required  for  the 
perfection  of  the  whole.     For  of  those  things  which  are 
required  not  principally,  but  only  on  account  of  something 
else,  he  does  not  select  any  definite  number  per  se ;  but  he 
accepts  and  uses  them  in  such  numbers  as  are  necessary  on 
account  of  that  other  thing.     For  instance,  a  builder  thinks 
out  the  definite  measurements  of  a  house,   and  also  the 
definite  number  of  rooms  which  he  wishes  to  make  in  the 
house;  and  definite  measurements  of  the  walls  and  the  roof; 
he  does  not,  however,  select  a  definite  number  of  stones, 
but  accepts  and  uses  just  so  many  as  are  sufficient  for  the 
required  measurements  of  the  wall.     So  also  must  we  con- 
sider concerning  God  in  regard  to  the  whole  universe,  which 
is  His  effect.     For  He  preordained  the  measurements  of 
the  whole  of  the  universe,  and  what  number  would  befit 
the  essential  parts  of  that  universe — that  is  to  say,  which 
have  in  some  way  been  ordained  in  perpetuity;  how  many 
spheres,  how  many  stars,  how  many  elements,  and  how 
many  species.     Individuals,  however,  which  undergo  cor- 


335  PREDESTINATION  Q.  23.  Art.  7 

ruption,  are  not  ordained  as  it  were  chiefly  for  the  good 
of  the  universe,  but  in  a  secondary  way,  inasmuch  as  the 
good  of  the  species  is  preserved  through  them.  Whence, 
although  God  knows  the  total  number  of  individuals,  the 
number  of  oxen,  flies,  and  such-like,  is  not  preordained  by 
God  per  se;  but  divine  providence  produces  just  so  many 
as  are  sufficient  for  the  preservation  of  the  species.  Now  of 
all  creatures  the  rational  creature  is  chiefly  ordained  for  the 
good  of  the  universe,  being  as  such  incorruptible;  more 
especially  those  who  attain  to  eternal  happiness,  since  they 
more  immediately  reach  the  ultimate  end.  Whence  the 
number  of  the  predestined  is  certain  to  God ;  not  only  by  way 
of  knowledge,  but  also  by  way  of  a  principal  preordination. 

It  is  not  exactly  the  same  thing  in  the  case  of  the  number 
of  the  reprobate,  who  would  seem  to  be  preordained  by  God 
for  the  good  of  the  elect,  in  whose  regard  all  things  work 
together  unto  good  (Rom.  viii.  28).  Concerning  the  number 
of  all  the  predestined,  some  say  that  so  many  men  will  be 
saved  as  angels  fell;  some,  so  many  as  there  were  angels 
left;  others,  as  many  as  the  number  of  angels  who  fell, 
added  to  that  of  all  the  angels  created  by  God.  It  is, 
however,  better  to  say  that,  to  God  alone  is  known  the  number 
for  whom  is  reserved  eternal  happiness.* 

Reply  Obj.  i.  These  words  of  Deuteronomy  must  be 
taken  as  applied  to  those  who  are  marked  out  by  God 
beforehand  in  respect  to  present  righteousness.  For  their 
number  is  increased  and  diminished,  but  not  the  number  of 
the  predestined. 

Reply  Obj.  2.  The  reason  of  the  quantity  of  any  one  part 
must  be  judged  from  the  proportion  of  that  part  to  the 
whole.  Thus  in  God  the  reason  why  He  has  made  so  many 
stars,  or  so  many  species  of  things,  or  predestined  so  many, 
is  according  to  the  proportion  of  the  principal  parts  to  the 
good  of  the  whole  universe. 

Reply  Obj.  3.  The  good  that  is  proportionate  to  the 
common  state  of  nature  is  to  be  found  in  the  majority;  and 
is  wanting  in  the  minority.     The  good  that  exceeds  the

Q.  23.  Art.  8    THE  "  SUMMA  THEOLOGICA  *'  336 

common  state  of  nature  is  to  be  found  in  the  minority,  and 
is  wanting  in  the  maj  ority .  Thus  it  is  clear  that  the  maj  ority 
of  men  have  a  sufficient  knowledge  for  the  guidance  of  hfe ; 
and  those  who  have  not  this  knowledge  are  said  to  be  half- 
witted or  f ooHsh ;  but  they  who  attain  to  a  profound  know- 
ledge of  things  intelligible  are  a  very  small  minority  in 
respect  to  the  rest.  Since  their  eternal  happiness,  consisting 
in  the  vision  of  God,  exceeds  the  common  state  of  nature, 
and  especially  in  so  far  as  this  is  deprived  of  grace  through 
the  corruption  of  original  sin,  those  who  are  saved  are  in 
the  minority.  In  this  especially,  however,  appears  the 
mercy  of  God,  that  He  has  chosen  some  for  that  salvation, 
from  which  very  many  in  accordance  with  the  common 
course  and  tendency  of  nature  fall  short. 

Eighth  Article. 

whether  predestination  can  be  furthered  by  the 
prayers  of  the  saints  ? 

We  proceed  thus  to  the  Eighth  Article  : — 

Objection  i.  It  seems  that  predestination  cannot  be 
furthered  by  the  prayers  of  the  saints.  For  nothing  eternal 
can  be  preceded  by  anything  temporal ;  and  in  consequence 
nothing  temporal  can  help  towards  making  something  else 
eternal.  But  predestination  is  eternal.  Therefore,  since 
the  prayers  of  the  saints  are  temporal,  they  cannot  so 
help  as  to  cause  anyone  to  become  predestined.  Pre- 
destination therefore  is  not  furthered  by  the  prayers  of 
the  saints. 

Ohj.  2.  Further,  as  there  is  no  need  of  advice  except  on 
account  of  defective  knowledge,  so  there  is  no  need  of  help 
except  through  defective  power.  But  neither  of  these  things 
can  be  said  of  God  when  He  predestines.  Whence  it  is  said: 
Who  hath  helped  the  Spirit  of  the  Lord  ?*  Or  who  hath  been 
His  counsellor?  (Rom.  xi.  34).  Therefore  predestination 
cannot  be  furthered  by  the  prayers  of  the  saints. 

Obj.  3.  Further,  if  a  thing  can  be  helped,  it  can  also  be 

*  Vulg^i  Who  hath  known  th^  mind  of  the  Lord  ? 


337  PREDESTINATION  Q.  23.  Art.  8 

hindered.     But  predestination  cannot  be  hindered  by  any- 
thing.    Therefore  it  cannot  be  furthered  by  anything. 

On  the  contrary,  It  is  said  that  Isaac  besought  the  Lord 
for  his  wife  because  she  was  barren;  and  He  heard  Him  and 
made  Rebecca  to  conceive  (Gen.  xxv.  21).  But  from  that 
conception  Jacob  was  born,  and  he  was  predestined.  Now 
his  predestination  would  not  have  happened  if  he  had  never 
been  born.  Therefore  predestination  can  be  furthered  by 
the  prayers  of  the  saints. 

/  answer  that,  Concerning  this  question,  there  were  different 
errors.  Some,  regarding  the  certainty  of  divine  predestina- 
tion, said  that  prayers  were  superfluous,  as  also  anything 
else  done  to  attain  salvation;  because  whether  these  things 
were  done  or  not,  the  predestined  would  attain,  and  the 
reprobate  would  not  attain,  eternal  salvation.  But  against 
this  opinion  are  all  the  warnings  of  Holy  Scripture,  exhorting 
us  to  prayer  and  other  good  works. 

Others  declared  that  the  divine  predestination  was 
altered  through  prayer.  This  is  stated  to  have  been  the 
opinion  of  the  Egyptians,  who  thought  that  the  divine 
ordination,  which  they  called  fate,  could  be  frustrated  by 
certain  sacrifices  and  prayers.  Against  this  also  is  the 
authority  of  Scripture.  For  it  is  said :  But  the  triumpher  in 
Israel  will  not  spare  and  will  not  be  moved  to  repentance 
(i  Kings  XV.  39) ;  and  that  the  gifts  and  the  calling  of  God  are 
without  repentance  (Rom.  xi.  29). 

Wherefore  we  must  say  otherwise  that  in  predestination 
two  things  are  to  be  considered — namely,  the  divine  pre- 
ordination; and  its  effect.  As  regards  the  former,  in  no 
possible  way  can  predestination  be  furthered  by  the  prayers 
of  the  saints.  For  it  is  not  due  to  their  prayers  that  anyone 
is  predestined  by  God.  As  regards  the  latter,  predestina- 
tion is  said  to  be  helped  by  the  prayers  of  the  saints,  and 
by  other  good  works ;  because  providence,  of  which  predes- 
tination is  a  part,  does  not  do  away  with  secondary  causes 
but  so  provides  effects,  that  the  order  of  secondary  causes 
falls  also  under  providence.  So,  as  natural  effects  are 
provided  by  God  in  such  a  way  that  natural  causes   are 

It  22 


Q.  23.  Art.  8    THE  "  SUMMA  THEOLOGICA  "  338 

directed  to  bring  about  those  natural  effects,  without  which 
those  effects  would  not  happen;  so  the  salvation  of  a  person 
is  predestined  by  God  in  such  a  way,  that  whatever  helps 
that  person  towards  salvation  falls  under  the  order  of 
predestination;  whether  it  be  one's  own  prayers,  or  those  of 
another ;  or  other  good  works,  and  suchUke,  without  which 
one  would  not  attain  to  salvation.  Whence,  the  predes- 
tined must  strive  after  good  works  and  prayer;  because 
through  these  means  predestination  is  most  certainly  ful- 
filled. For  this  reason  it  is  said:  Labour  the  more  that  by 
good  works  you  may  make  sure  your  calling  and  election 
(2  Pet.  i.  10). 

Reply  Obj.  i.  This  argument  shows  that  predestination 
is  not  furthered  by  the  prayers  of  the  saints,  as  regards 
the  preordination. 

Reply  Obj,  z.  One  is  said  to  be  helped  by  another  in  two 
ways;  in  one  way,  inasmuch  as  he  receives  power  from 
him:  and  to  be  helped  thus  belongs  to  the  weak;  but  this 
cannot  be  said  of  God,  and  thus  we  are  to  understand.  Who 
hath  helped  the  Spirit  of  the  Lord  ?  In  another  way  one  is 
said  to  be  helped  by  a  person  through  whom  he  carries  out 
his  work,  as  a  master  through  a  servant.  In  this  way  God 
is  helped  by  us ;  inasmuch  as  we  execute  His  orders,  accord- 
ing to  I  Cor.  iii.  9:  We  are  God's  coadjutors.  Nor  is  this  on 
account  of  any  defect  in  the  power  of  God,  but  because  He 
employs  intermediary  causes,  in  order  that  the  beauty  of 
order  may  be  preserved  in  the  universe;  and  also  that  He 
may  communicate  to  creatures  the  dignity  of  causality. 

Reply  Obj,  3.  Secondary  causes  cannot  escape  the  order 
of  the  first  universal  cause,  as  has  been  said  above  (Q.  XIX., 
A.  6),  indeed,  they  execute  that  order.  And  therefore 
predestination  can  be  furthered  by  creatures,  but  it  cannot 
be  impeded  by  them. 


QUESTION  XXIV. 

THE   BOOK   OF   LIFE. 
{In  Three  Articles.) 

We  now  consider  the  book  of  life;  concerning  which  there 
are  three  points  of  inquiry:  (i)  What  is  the  book  of  hfe  ? 
(2)  Of  what  Hfe  is  it  the  book  ?  (3)  Whether  anyone  can 
be  blotted  out  of  the  book  of  life  ? 

First  Article. 

whether  the  book  of  life  is  the  same  as 
predestination  ? 

We  proceed  thus  to  the  First  Article  : — 

Objection  i.  It  seems  that  the  book  of  life  is  not  the 
same  thing  as  predestination.  For  it  is  said,  All  these 
things  are  the  hook  of  life  (Ecclus.  xxiv.  32) — i.e.  the  Old  and 
New  Testament  according  to  a  gloss.  This,  however,  is  not 
predestination.  Therefore  the  book  of  life  is  not  predestina- 
tion. 

Ohj.  2.  Further,  Augustine  says  {De  Civ.  Dei,  xx.  14)  that 
the  hook  of  life  is  a  certain  divine  energy,  hy  which  it  happens 
that  to  each  one  his  good  or  evil  works  are  recalled  to  memory. 
But  divine  energy  belongs  seemingly,  not  to  predestina- 
tion, but  rather  to  divine  power.  Therefore  the  book  of 
life  is  not  the  same  thing  as  predestination. 

Ohj.  3.  Further,  Reprobation  is  opposed  to  predestination* 
So,  if  the  book  of  life  were  the  same  as  predestination,  there 
should  also  be  a  book  of  death,  as  there  is  a  book  of  life. 

On  the  contrary,  It  is  said  in  a  gloss  upon  Ps.  Ixviii.  29, 
Let  them  be  blotted  out  of  the  book  of  the  living:  This  book  is  th^ 

339 


Q.  24.  Art.  i    THE  "  SUMMA  THEOLOGICA  "  340 

knowledge  of  God,  by  iMch  He  hath  predestined  to  life  those 
whom  He  foreknew. 

I  answer  that,  The  book  of  life  is  in  God  taken  in  a  meta- 
phorical sense,  according  to  a  comparison  with  human 
affairs.  For  it  is  usual  among  men  that  they  who  are 
chosen  for  any  office  should  be  inscribed  in  a  book;  as, 
for  instance,  soldiers,  or  counsellors,  who  formerly  were 
called  conscript  fathers.  Now  it  is  clear  from  the  preceding 
(Q.  XXIII. ,  A.  4)  that  all  the  predestined  are  chosen  by 
God  to  possess  eternal  life.  This  conscription,  therefore,  of 
the  predestined  is  called  the  book  of  hfe.  A  thing  is  said 
metaphorically  to  be  written  upon  the  mind  of  anyone  when 
it  is  firmly  held  in  the  memory,  according  to  Prov.  (iii.  3) : 
Forget  not  My  law,  and  let  thy  heart  keep  My  commandments, 
and  further  on,  Write  them  in  the  tables  of  thy  heart.  For 
things  are  written  down  in  material  books  to  help  the 
memory.  Whence,  the  knowledge  of  God,  by  which  He 
firmly  remembers  that  He  has  predestined  some  to  eternal 
life,  is  called  the  book  of  hfe.  For  as  the  writing  in  a  book 
is  the  sign  of  things  to  be  done,  so  the  knowledge  of  God 
is  a  sign  in  Him  of  those  who  are  to  be  brought  to  eternal 
life,  according  to  2  Tim.  ii.  19 :  The  sure  foundation  of  God 
standeth  firm,  having  this  seal;  the  Lord  knoweth  who  are  His. 

Reply  Obj.  i.  The  book  of  life  may  be  understood  in  two 
senses.  In  one  sense  as  the  inscription  of  those  who  are 
chosen  to  life;  thus  we  now  speak  of  the  book  of  life.  In 
another  sense  the  inscription  of  those  things  which  lead 
us  to  life  may  be  called  the  book  of  life;  and  this  also  is 
twofold,  either  as  of  things  to  be  done;  and  thus  the  Old 
and  New  Testaments  are  called  a  book  of  hfe;  or  of  things 
already  done,  and  thus  that  divine  energy  by  wliich  it 
happens  that  to  each  one  his  deeds  will  be  recalled  to 
memory,  is  spoken  of  as  the  book  of  hfe.  Thus  that  also 
may  be  called  the  book  of  war,  whether  it  contains  the  names 
inscribed  of  those  chosen  for  mihtary  service;  or  treats  of 
the  art  of  warfare,  or  relates  the  deeds  of  soldiers. 

Hence  the  solution  of  the  Second  Objection  is  clear. 

Reply  Obj.  3.  It  is  the  custom  to  inscribe,  not  those  whp 


341  THE  BOOK  OF  LIFE  Q.  24.  Art.  2 

are  rejected,  but  those  who  are  chosen.  Whence  there  is 
no  book  of  death  corresponding  to  reprobation ;  as  the  book 
of  life  to  predestination. 

Reply  Ohj.  4.  Predestination  and  the  book  of  life  are 
different  aspects  of  the  same  thing.  For  this  latter  implies 
the  knowledge  of  predestination;  as  also  is  made  clear  from 
the  gloss  quoted  above. 


Second  Article. 

whether  the  book  of  life  regards  only  the  life  of 
glory  of  the  predestined  ? 

We  proceed  thus  to  the  Second  Article  : — 

Objection  i.  It  seems  that  the  book  of  life  does  not  only 
regard  the  life  of  glory  of  the  predestined.  For  the  book 
of  life  is  the  knowledge  of  life.  But  God,  through  His 
own  life,  knows  all  other  life.  Therefore  the  book  of  life 
is  so  called  in  regard  to  divine  life ;  and  not  only  in  regard 
to  the  life  of  the  predestined. 

Ohj.  2.  Further,  as  the  life  of  glory  comes  from  God,  so 
also  does  the  life  of  nature.  Therefore,  if  the  knowledge 
of  the  life  of  glory  is  called  the  book  of  life ;  so  also  should 
the  knowledge  of  the  life  of  nature  be  so  called. 

Ohj.  3.  Further,  some  are  chosen  to  the  life  of  grace  who 
are  not  chosen  to  the  life  of  glory ;  as  is  clear  from  what  is 
said :  Have  not  I  chosen  you  twelve,  and  one  of  you  is  a  devil  ? 
(John  vi.  71).  But  the  book  of  life  is  the  inscription  of 
the  divine  election,  as  stated  above  (A.  i).  Therefore  it 
applies  also  to  the  life  of  grace. 

On  the  contrary,  The  book  of  life  is  the  knowledge  of 
predestination,  as  stated  above  [ihid.].  But  predestination 
does  not  regard  the  life  of  grace,  except  so  far  as  it  is  directed 
to  glory;  for  those  are  not  predestined  who  have  grace 
and  yet  fail  to  obtain  glory.  The  book  of  Hfe  therefore  is 
only  so  called  in  regard  to  the  life  of  glory. 

I  answer  that,  The  book  of  life,  as  stated  above  {ihid.), 
implies  a  conscription  or  a  knowledge  of  those  chosen  to 
life.     Now  a  man  is  chosen  for  something  which  does  not 


Q.  24.  Art.  3    THE  "  SUMMA  THEOLOGICA  ''  342 

belong  to  him  by  nature;  and  again  that  to  which  a  man 
is  chosen  has  the  aspect  of  an  end.  For  a  soldier  is  not 
chosen  or  inscribed  merely  to  put  on  armour,  but  to  fight; 
since  this  is  the  proper  duty  to  which  miUtary  service  is 
directed.  But  the  life  of  glory  is  an  end  exceeding  human 
nature,  as  said  above  (Q.  XXII I. ,  A.  i).  Wherefore, 
strictly  speaking,  the  book  of  life  regards  the  life  of  glory. 

Reply  Ohj.  i.  The  divine  life,  even  considered  as  a  life  of 
glory,  is  natural  to  God;  whence  in  His  regard  there  is  no 
election,  and  in  consequence  no  book  of  life :  for  we  do  not 
say  that  anyone  is  chosen  to  possess  the  power  of  sense, 
or  any  of  those  things  that  are  consequent  on  nature. 

From  this  we  gather  the  Reply  to  the  Second  Objection. 
For  there  is  no  election,  nor  a  book  of  life  as  regards  the  life 
of  nature. 

Reply  Ohj.  3.  The  life  of  grace  has  the  aspect,  not  of  an 
end,  but  of  something  directed  towards  an  end.  Hence 
nobody  is  said  to  be  chosen  to  the  life  of  grace,  except  so 
far  as  the  life  of  grace  is  directed  to  glory.  For  this  reason 
those  who,  possessing  grace,  fail  to  obtain  glory,  are  not 
said  to  be  chosen  simply,  but  relatively.  Likewise  they 
are  not  said  to  be  written  in  the  book  of  life  simply,  but 
relatively;  that  is  to  say,  that  it  is  in  the  ordination  and 
knowledge  of  God  that  they  are  to  have  some  relation  to 
eternal  life,  according  to  their  participation  in  grace. 

Third  Article, 
whether  anyone  may  be  blotted  out  of  the  book 

OF  LIFE  ? 

We  proceed  thus  to  the  Third  Article  : — 

Objection  i.  It  seems  that  no  one  may  be  blotted  out  of 
the  book  of  life.  For  Augustine  says  {De  Civ.  Dei,  xx.  15) : 
God*s  foreknowledge,  which  cannot  he  deceived,  is  the  book  of 
life.  But  nothing  can  be  taken  away  from  the  foreknow- 
ledge of  God,  nor  from  predestination.  Therefore  neither 
can  anyone  be  blotted  out  from  the  book  of  life. 

Obj.  2.  Further,  whatever  is  in  a  thing,  is  in  it  according 


343  THE  BOOK  OF  LIFE  Q.  24.  Art.  3 

to  the  disposition  of  that  thing.  But  the  book  of  life  is 
something  eternal  and  immutable.  Therefore  whatsoever 
is  written  therein,  is  there  not  in  a  temporary  way,  but 
immovably  and  indelibly. 

Ohj.  3.  Further,  blotting  out  is  the  contrary  to  inscripi- 
tion.  But  nobody  can  be  written  a  second  time  in  the 
book  of  life.     Neither  therefore  can  he  be  blotted  out. 

On  the  contrary,  It  is  said,  Let  them  be  blotted  out  from  the 
book  of  the  living  (Ps.  Ixviii.  29). 

/  answer  that,  Some  have  said  that  none  could  be  blotted 
out  of  the  book  of  life  as  a  matter  of  fact,  but  only  in  the 
opinion  of  men.     For  it  is  customary  in  the  Scriptures 
to  say  that  something  is  done  when  it  becomes  known. 
Thus  some  are  said  to  be  written  in  the  book  of  life,  inas- 
much as  men  think  they  are  written  therein,  on  account 
of  the  present  righteousness  they  see  in  them;  but  when  it 
becomes  evident,  either  in  this  world  or  in  the  next,  that 
they  have  fallen  from  that  state  of  righteousness,  they  are 
then  said  to  be  blotted  out.     And  thus  a  gloss  explains  the 
passage :  Let  them  be  blotted  out  of  the  book  of  the  living.     But 
because  not  to  be  blotted  out  of  the  book  of  life  is  placed 
among  the  rewards  of  the  just,  according  to  the  text,  He 
that  shall  overcome,  shall  thus  be  clothed  in  white  garments, 
and  I  will  not  blot  his  name  out  of  the  book  of  life  (Apoc.  iii.  5) 
(and  what  is  promised  to  holy  men,  is  not  merely  something 
in  the  opinion  of  men),  it  can  therefore  be  said  that  to  be 
blotted  out,  and  not  blotted  out,  of  the  book  of  life  is  not 
only  to  be  referred  to  the  opinion  of  man,  but  to  the  reality 
of  the  fact.     For  the  book  of  life  is  the  inscription  of  those 
ordained  to  eternal  life,  to  which  one  is  directed  from  two 
sources;    namely,    from    predestination,    which    direction 
never  fails,   and  from  grace;  for  whoever  has  grace,  by 
this  very  fact  becomes  fitted  for  eternal  life.     This  direction 
fails  sometimes;  because  some  are  directed,  by  possessing 
grace,  to  obtain  eternal  life,  yet  they  fail  to  obtain  it  through 
mortal  sin.     Therefore  those  who  are  ordained  to  possess 
eternal  life  through  divine  predestination  are  written  down 
in  the  book  of  life  simply,  because  they  are  written  therein 


Q.  24.  Art.  3    THE  "  SUMMA  THEOLOGICA  '^  344 

to  have  eternal  life  in  reality;  such  are  never  blotted  out 
from  the  book  of  life.  Those,  however,  who  are  ordained 
to  eternal  life,  not  through  the  divine  predestination,  but 
through  grace,  are  said  to  be  written  in  the  book  of  life 
not  simply,  but  relatively,  for  they  are  written  therein 
not  to  have  eternal  life  in  itself,  but  in  its  cause  only.  Yet 
though  these  latter  can  be  said  to  be  blotted  out  of  the  book 
of  life,  this  blotting  out  must  not  be  referred  to  God,  as  if 
God  foreknew  a  thing,  and  afterwards  knew  it  not ;  but  to 
the  thing  known,  namely,  because  God  knows  one  is  first 
ordained  to  eternal  life,  and  afterwards  not  ordained  when 
he  falls  from  grace. 

Reply  Obj.  i.  The  act  of  blotting  out  does  not  refer  to  the 
book  of  life  as  regards  God's  foreknowledge,  as  if  in  God 
there  were  any  change;  but  as  regards  things  foreknown, 
which  can  change. 

Reply  Obj.  2.  Although  things  are  immutably  in  God, 
yet  in  themselves  they  are  subject  to  change.  To  this  it  is 
that  the  blotting  out  of  the  book  of  life  refers. 

Reply  Obj.  3.  The  way  in  which  one  is  said  to  be  blotted 
out  of  the  book  of  life  is  that  in  which  one  is  said  to  be 
written  therein  anew;  either  in  the  opinion  of  men,  or  be- 
cause he  begins  again  to  have  relation  towards  eternal  life 
through  grace;  which  also  is  included  in  the  knowledge 
of  God,  although  not  anew. 


QUESTION  XXV. 

THE  POWER  OF  GOD. 

{In  Six  Articles.) 

After  considering  the  divine  foreknowledge  and  will, 
and  other  things  pertaining  thereto,  it  remains  for  us  to 
consider  the  power  of  God.  About  this  are  six  points  of 
inquiry :  (i)  Whether  there  is  power  in  God  ?  (2)  Whether 
His    power    is    infinite  ?     (3)    Whether    He    is    almighty  ? 

(4)  Whether  He  could  make  the  past  not  to  have  been  ? 

(5)  Whether  He  could  do  what  He  does  not,  or  not  do  what 
He  does  ?  (6)  Whether  what  He  makes  He  could  make 
better  ? 

First  Article, 
whether  there  is  power  in  god  ? 

We  proceed  thus  to  the  First  Article: — 

Objection  i.  It  seems  that  power  is  not  in  God.  For  as 
primary  matter  is  to  power,  so  God,  who  is  the  first  agent, 
is  to  act.  But  primary  matter,  considered  in  itself,  is 
devoid  of  all  act.  Therefore,  the  first  agent — namely,  God 
— is  devoid  of  power. 

Ohj.  2.  Further,  according  to  the  Philosopher  (Metaph. 
vi.  19),  better  than  every  power  is  its  act.  For  form  is 
better  than  matter;  and  action  than  active  power,  since 
it  is  its  end.  But  nothing  is  better  than  w^hat  is  in  God; 
because  whatsoever  is  in  God,  is  God,  as  was  shown  above 
(Q.  III.,  A.  3).     Therefore,  there  is  no  power  in  God. 

Obj.  3.  Further,  Power  is  the  principle  of  operation.  But 
the  divine  power  is  God's  essence,  since  there  is  nothing 
accidental  in  God:  and  of  the  essence  of  God  there  is  no 
principle.     Therefore  there  is  no  power  in  God.

Q.  25.  Art.  i     THE  "  SUMMA  THEOLOGICA  "  346 

Obj.  4.  Further,  it  was  shown  above  (QQ.  XIV.,  A.  8; 
XIX.,  A.  4)  that  God's  knowledge  and  will  are  the  cause 
of  things.  But  the  cause  and  principle  of  a  thing  are  iden- 
tical. We  ought  not,  therefore,  to  assign  power  to  God; 
but  only  knowledge  and  will. 

On  the  contrary,  It  is  said:  Thou  art  mighty,  0  Lord,  and 
Thy  truth  is  round  about  Thee  (Ps.  Ixxxviii.  g). 

/  answer  that,  Power  is  twofold — namely,  passive,  which 
exists  not  at  all  in  God;  and  active,  which  we  must  assign 
to  Him  in  the  highest  degree.  For  it  is  manifest  that 
everything,  according  as  it  is  in  act  and  is  perfect,  is  the 
active  principle  of  something :  whereas  everything  is  passive 
according  as  it  is  deficient  and  imperfect.  Now  it  was 
shown  above  (QQ.  III.,  A.  2;  IV.,  AA.  i,  2),  that  God  is 
pure  act,  simply  and  in  all  ways  perfect,  nor  in  Him  does 
any  imperfection  find  place.  Whence  it  most  fittingly 
belongs  to  Him  to  be  an  active  principle,  and  in  no  wa\' 
whatsoever  to  be  passive.  On  the  other  hand,  the  notion 
of  active  principle  is  consistent  with  active  power.  For 
active  power  is  the  principle  of  acting  upon  something  else ; 
whereas  passive  power  is  the  principle  of  being  acted  upon 
by  something  else,  as  the  Philosopher  says  (Metaph.  v.  17). 
It  remains,  therefore,  that  in  God  there  is  active  power  in 
the  highest  degree. 

Reply  Obj,  i.  Active  power  is  not  contrary  to  act,  but  is 
founded  upon  it,  for  everything  acts  according  as  it  is 
actual:  but  passive  power  is  contrary  to  act;  for  a  thing 
is  passive  according  as  it  is  potential.  Whence  this  poten- 
tiality is  not  in  God,  but  onl}''  active  power. 

Reply  Obj.  2.  Whenever  act  is  distinct  from  power,  act 
must  be  nobler  than  power.  But  God's  action  is  not 
distinct  from  His  power,  for  both  are  His  divine  essence; 
neither  is  His  existence  distinct  from  His  essence.  Hence 
it  does  not  follow  that  there  should  be  anything  in  God 
nobler  than  His  power. 

Reply  Obj.  3.  In  creatures,  power  is  the  principle  not  only 
of  action,  but  likewise  of  effect.  Thus  in  God  the  idea  of 
power  is  retained,  inasmuch  as  it  is  the  principle  of  an 


347  THE  POWER  OF  GOD  Q.25.ART.4 

effect;  not,  however,  as  it  is  a  principle  of  action,  for  this 
is  the  divine  essence  itself;  except,  perchance,  after  our 
manner  of  understanding,  inasmuch  as  the  divine  essence, 
which  precontains  in  itself  all  perfection  that  exists  in 
created  things,  can  be  understood  either  under  the  notion 
of  action,  or  under  that  of  power;  as  also  it  is  understood 
under  the  notion  of  a  suppositum  possessing  nature,  and 
under  that  of  nature.  Accordingly  the  notion  of  power 
is  retained  in  God  in  so  far  as  it  is  the  principle  of  an  effect. 

Reply  Ohj.  4.  Power  is  predicated  of  God  not  as  some- 
thing really  distinct  from  His  knowledge  and  will,  but 
as  differing  from  them  logically;  inasmuch  as  power  implies 
a  notion  of  a  principle  putting  into  execution  what  the  will 
commands,  and  what  knowledge  directs,  which  three  things 
in  God  are  identified.  Or  we  may  say,  that  the  knowledge 
or  will  of  God,  according  as  it  is  the  effective  principle,  has 
the  notion  of  power  contained  in  it.  Hence  the  consideration 
of  the  knowledge  and  will  of  God  precedes  the  consideration 
of  His  power,  as  the  cause  precedes  the  operation  and  effect. 

Second  Article, 
whether  the  power  of  god  is  infinite  ? 

We  proceed  thus  to  the  Second  Article: — 

Objection  1.  It  seems  that  the  power  of  God  is  not  infinite. 
For  everything  that  is  infinite  is  imperfect  according  to  the 
Philosopher  (Phys.  iii.  6).  But  the  power  of  God  is  far  from 
imperfect.     Therefore  it  is  not  infinite. 

Obj.  2.  Further,  every  power  is  made  known  by  its 
effect;  otherwise  it  would  be  ineffectual.  If,  then,  the 
power  of  God  were  infinite,  it  could  produce  an  infinite  effect , 
but  this  is  impossible. 

Obj.  3.  Further,  the  Philosopher  proves  (Phys.  viii.  79) 
that  if  the  power  of  any  corporeal  thing  were  infinite,  it 
would  cause  instantaneous  movement.  God,  however, 
does  not  cause  instantaneous  movement,  but  moves  the 
spiritual  creature  in  time,  and  the  corporeal  creature  in 
place  and  time,  as  Augustine  says  (Gen.  ad  lit.  20,  22,  23). 
Therefore,  His  power  is  not  infinite. 


Q.  25.  Art.  2    THE  "  SUMMA  THEOLOGICA  "  348 

On  the  contrary,  Hilary  says  [De  Trin.  viii.),  that  God's 
power  is  immeasurable.  He  is  the  living  ^nighty  One.  Now 
everything  that  is  immeasurable  is  infinite.  Therefore  the 
power  of  God  is  infinite. 

/  answer  that,  As  stated  above  (A.  i),  active  power  exists 
in  God  according  to  the  measure  in  which  He  is  actual. 
Now  His  existence  is  infinite,  inasmuch  as  it  is  not  limited  by 
anything  that  receives  it,  as  is  clear  from  what  has  been  said, 
when  we  discussed  the  infinity  of  the  divine  essence  (Q.  VH., 
A.  i).  Wherefore,  it  is  necessary  that  the  active  power  in 
God  should  be  infinite.  For  in  every  agent  is  it  found  that 
the  more  perfectly  an  agent  has  the  form  by  which  it  acts 
the  greater  its  power  to  act.  For  instance,  the  hotter  a 
thing  is,  the  greater  power  has  it  to  give  heat ;  and  it  would 
have  infinite  power  to  give  heat,  were  its  own  heat  infinite. 
Whence,  since  the  divine  essence,  through  which  God  acts, 
is  infinite,  as  was  shown  above  {I.e.),  it  follows  that  His 
power  likewise  is  infinite. 

Reply  Obj.  i.  The  Philosopher  is  here  speaking  of  an 
infinity  in  regard  to  matter  not  Hmited  by  any  form;  and 
such  infinity  belongs  to  quantity.  But  the  divine  essence 
is  otherwise,  as  was  shown  above  (Lc);  and  consequently 
so  also  His  power.  It  does  not  follow,  therefore,  that  it  is 
imperfect. 

Reply  Obj.  2.  The  power  of  a  uni vocal  agent  is  wholly 
manifested  in  its  effect.  The  generative  power  of  man,  for 
example,  is  not  able  to  do  more  than  beget  man.  But  the 
power  of  a  non-univocal  agent  does  not  wholly  manifest 
itself  in  the  production  of  its  effect:  as,  for  example,  the 
power  of  the  sun  does  not  wholly  manifest  itself  in  the 
production  of  an  animal  generated  from  putrefaction.  Now 
it  is  clear  that  God  is  not  a  univocal  agent.  For  nothing 
agrees  with  Him  either  in  species  or  in  genus,  as  was  shown 
above  (QQ.  HI.,  A.  5,  and  IV.,  A.  3).  Whence  it  follows 
that  His  effect  is  always  less  than  His  power.  It  is  not 
necessary,  therefore,  that  the  infinite  power  of  God  should  be 
manifested  so  as  to  produce  an  infinite  effect.  Yet  even  if  it 
were  to  produce  no  effect,  the  power  of  God  would  not  be 


349  THE  POWER  OF  GOD  Q.  25.  Art.  3 

ineffectual ;  because  a  thing  is  ineffectual  which  is  ordained 
towards  an  end  to  which  it  does  not  attain.  But  the  power 
of  God  is  not  ordered  toward  its  effect  as  towards  an  end; 
rather,  it  is  the  end  of  the  effect  produced  by  it. 

Reply  Ohj.  3.  The  Philosopher  {Phys.  viii.  79)  proves  that 
if  a  body  had  infinite  power,  it  would  cause  a  non-temporal 
movement.  And  he  shows  that  the  power  of  the  mover  of 
heaven  is  infinite,  because  it  can  move  in  an  infinite  time.  It 
remains,  therefore,  according  to  his  reckoning,  that  the 
infinite  power  of  a  body,  if  such  existed,  would  move  without 
time ;  not,  however,  the  power  of  an  incorporeal  mover.  The 
reason  of  this  is  that  one  body  moving  another  is  a  univocal 
agent ;  wherefore  it  follows  that  the  whole  power  of  the  agent 
is  made  known  in  its  motion.  Since  then  the  greater  the 
power  of  a  moving  body,  the  more  quickly  does  it  move ;  the 
necessary  conclusion  is  that  if  its  power  were  infinite  it  would 
move  beyond  comparison  faster,  and  this  is  to  move  without 
time.  An  incorporeal  mover,  however,  is  not  a  univocal 
agent ;  whence  it  is  not  necessary  that  the  whole  of  its  power 
should  be  manifested  in  motion,  so  as  to  move  without  time ; 
and  especially  since  it  moves  in  accordance  with  the  dis- 
position of  its  will. 

Third  Article, 
whether  god  is  omnipotent  ? 

We  proceed  thus  to  the  Third  Article : — 

Objection  i.  It  seems  that  God  is  not  omnipotent.  For 
movement  and  passiveness  belong  to  everything.  But  this 
is  impossible  with  God,  for  He  is  immovable,  as  was  said 
above  (Q.  II.,  A.  3).     Therefore  He  is  not  omnipotent. 

Ohj.  2.  Further,  sin  is  an  act  of  some  kind.  But  God 
cannot  sin,  nor  deny  Himself,  as  it  is  said  2  Tim.  ii.  13. 
Therefore  He  is  not  omnipotent. 

Ohj.  3.  Further,  it  is  said  of  God  that  He  manifests  His 
omnipotence  especially  hy  sparing  and  having  mercy.* 
Therefore  the  greatest  act  possible  to  the  divine  power  is 
to  spare  and  have  mercy.     There  are  things  much  greater, 

*  Collect,  tenth  Sunday  after  Pentecost. 


Q.  25.  Art.  3    THE  "  SUMMA  THEOLOGICA ''  350 

however,  than  sparing  and  having  mercy;  for  example,  to 
create  another  world,  and  the  Uke.  Therefore  God  is  not 
omnipotent. 

Ohj.  4.  Further,  upon  the  text,  God  hath  made  foolish 
the  wisdom  of  this  world  (i  Cor.  i.  20),  a  gloss  says:  God 
hath  made  the  wisdom  of  this  world  foolish,^  by  showing  those 
things  to  he  possible  which  it  judges  to  be  impossible.  Whence 
it  would  seem  that  nothing  is  to  be  judged  possible  or  im- 
possible in  reference  to  inferior  causes,  as  the  wisdom  of 
this  world  judges  them;  but  in  reference  to  the  divine 
power.  If  God,  then,  were  omnipotent,  all  things  would 
be  possible;  nothing,  therefore,  impossible.  But  if  we  take 
away  the  impossible,  then  we  destroy  also  the  necessary; 
for  what  necessarily  exists  is  impossible  not  to  exist.  There- 
fore there  would  be  nothing  at  all  that  is  necessary  in  things 
if  God  were  omnipotent.  But  this  is  an  impossibility. 
Therefore  God  is  not  omnipotent. 

On  the  contrary,  It  is  said:  No  word  shall  be  impossible 
with  God  (Luke  i.  37). 

/  answer  that,  All  confess  that  God  is  omnipotent;  but 
it  seems  difficult  to  explain  in  what  His  omnipotence  precisely 
consists:  for  there  may  be  a  doubt  as  to  the  precise  meaning 
of  the  word  "  all  "  when  we  say  that  God  can  do  all  things. 
If,  however,  we  consider  the  matter  aright,  since  power  is  said 
in  reference  to  possible  things,  this  phrase,  God  ca?i  do  all 
things,  is  rightly  understood  to  mean  that  God  can  do  all 
things  that  are  possible ;  and  for  this  reason  He  is  said  to  be 
omnipotent.  Now  according  to  the  Philosopher  {Mefaph. 
V.  17),  a  thing  is  said  to  be  possible  in  two  ways.  First  in 
relation  to  some  power,  thus  whatever  is  subject  to  human 
power  is  said  to  be  possible  to  man.  Secondly  absolutely, 
on  account  of  the  relation  in  which  the  very  terms  stand  to 
each  other.  Now  God  cannot  be  said  to  be  omnipotent 
through  being  able  to  do  all  things  that  are  possible  to  created 
nature;  for  the  divine  power  extends  farther  than  that. 
If,  however,  we  were  to  say  that  God  is  omnipotent  because 
He  can  do  all  things  that  are  possible  to  His  power,  there 

*  Vulg.,  Hath  not  God,  etc: 


351  THE  POWER  OF  GOD  Q.  25.  Art.  3 

would  be  a  vicious  circle  in  explaining  the  nature  of  His 
power.  For  this  would  be  saying  nothing  else  but  that 
God  is  omnipotent,  because  He  can  do  all  that  He  is  able 
to  do. 

It  remains,  therefore,  that  God  is  called  omnipotent 
because  he  can  do  all  things  that  are  possible  absolutely; 
which  is  the  second  way  of  saying  a  thing  is  possible.  For 
a  thing  is  said  to  be  possible  or  impossible  absolutely, 
according  to  the  relation  in  which  the  very  terms  stand  to 
one  another,  possible  if  the  predicate  is  not  incompatible 
with  the  subject,  as  that  Socrates  sits;  and  absolutely 
impossible  when  the  predicate  is  altogether  incompatible 
with  the  subject,  as,  for  instance,  that  a  man  is  a  donkey. 

It  must,  however,  be  remembered  that  since  every  agent 
produces  an  effect  like  itself,  to  each  active  power  there 
corresponds  a  thing  possible  as  its  proper  object  according 
to  the  nature  of  that  act  on  which  its  active  power  is  founded; 
for  mstance,  the  power  of  giving  warmth  is  related  as  to  its 
proper  object  to  the  being  capable  of  being  warmed.  The 
divine  existence,  however,  upon  which  the  nature  of  power 
in  God  is  founded,  is  infinite,  and  is  not  limited  to  any  genus 
of  being;  but  possesses  within  itself  the  perfection  of  all 
being.  Whence,  w^hatsoever  has  or  can  have  the  nature  of 
being,  is  numbered  among  the  absolutely  possible  things, 
in  respect  of  which  God  is  called  omnipotent.  Now  nothing 
is  opposed  to  the  idea  of  being  except  non-being.  There- 
fore, that  which  implies  being  and  non-being  at  the  same 
time  is  repugnant  to  the  idea  of  an  absolutely  possible 
thing,  within  the  scope  of  the  divine  omnipotence.  For 
such  cannot  come  under  the  divine  omnipotence,  not  because 
of  any  defect  in  the  power  of  God,  but  because  it  has  not 
the  nature  of  a  feasible  or  possible  thing.  Therefore, 
everything  that  does  not  imply  a  contradiction  in  terms, 
is  numbered  amongst  those  possible  things,  in  respect  of 
which  God  is  called  omnipotent :  whereas  whatever  implies 
contradiction  does  not  come  within  the  scope  of  divine 
omnipotence,  because  it  cannot  have  the  aspect  of  possi- 
bility.    Hence  it  is  better  to  say  that  such  things  cannot 


Q.  25.  Art.  3    THE  "  SUMMA  THEOLOGICA  "  352 

be  done,  than  that  God  cannot  do  them.  Nor  is  this 
contrary  to  the  word  of  the  angel,  saying :  No  word  shall  be 
impossible  with  God.  For  whatever  imphes  a  contradiction 
cannot  be  a  word,  because  no  intellect  can  possibly  conceive 
such  a  thing. 

Reply  Obj.  i.  God  is  said  to  be  omnipotent  in  respect  to 
His  active  power,  not  to  passive  power,  as  was  shown 
above  (A.  i).  Whence  the  fact  that  He  is  immovable  or 
impassible  is  not  repugnant  to  His  omnipotence. 

Reply  Obj.  2.  To  sin  is  to  fall  short  of  a  perfect  action; 
hence  to  be  able  to  sin  is  to  be  able  to  fall  short  in  action, 
which  is  repugnant  to  omnipotence.  Therefore  it  is  that 
God  cannot  sin,  because  of  His  omnipotence.  Never- 
theless, the  Philosopher  says  (Top.  iv.  3)  that  God  can 
deliberately  do  what  is  evil.  But  this  must  be  understood 
either  on  a  condition,  the  antecedent  of  which  is  impossible — 
as,  for  instance,  if  we  were  to  say  that  God  can  do  evil 
things  if  He  will.  For  there  is  no  reason  why  a  conditional 
proposition  should  not  be  true,  though  both  the  antecedent 
and  consequent  are  impossible :  as  if  one  were  to  say :  //  man 
is  a  donkey,  he  has  Jour  feet.  Or  he  may  be  understood  to 
mean  that  God  can  do  some  things  which  now  seem  to  be 
evil :  which,  however,  if  He  did  them,  would  then  be  good. 
Or  he  is,  perhaps,  speaking  after  the  common  manner  of  the 
heathen,  who  thought  that  men  became  gods,  like  Jupiter 
or  Mercury. 

Reply  Obj.  3.  God's  omnipotence  is  particularly  shown 
in  sparing  and  having  mercy,  because  in  this  is  it  made 
manifest  that  God  has  supreme  power,  that  He  freely 
forgives  sins.  For  it  is  not  for  one  who  is  bound  by  laws 
of  a  superior  to  forgive  sins  of  his  own  free  will.  Or,  because 
by  sparing  and  having  mercy  upon  men,  He  leads  them  on 
to  the  participation  of  an  infinite  good;  which  is  the  ulti- 
mate effect  of  the  divine  power.  Or  because,  as  was  said 
above  (Q.  XXL,  A.  4),  the  effect  of  the  divine  mercy  is  the 
foundation  of  all  the  divine  works.  For  nothing  is  due  to 
anyone,  except  on  account  of  something  already  given  him 
gratuitously  by  God.     In  this  way  the  divine  omnipotence 


353  i'HE  POWER  OF  GOD  Q.  25.  Art.  4 

is  particiilarly  made  manifest,  because  to  it  pertains  the  first 
foundation  of  all  good  things. 

Reply  Obj.  4.  The  absolute  possible  is  not  so  called  in 
reference  either  to  higher  causes,  or  to  inferior  causes, 
but  in  reference  to  itself.  But  the  possible  in  reference 
to  some  power  is  named  possible  in  reference  to  its  proxi- 
mate cause.  Hence  those  things  which  it  belongs  to  God 
alone  to  do  immediately — as,  for  example,  to  create,  to 
justify,  and  the  like — are  said  to  be  possible  in  reference  to 
a  higher  cause.  Those  things,  however,  which  are  of  such 
kind  as  to  be  done  by  inferior  causes  are  said  to  be  possible 
in  reference  to  those  inferior  causes.  For  it  is  according 
to  the  condition  of  the  proximate  cause  that  the  effect  has 
contingency  or  necessity,  as  was  shown  above  (Q.  XIV., 
A.  I,  ad  2).  Thus  is  it  that  the  wisdom  of  the  world  is 
deemed  foolish,  because  what  is  impossible  to  nature,  it 
judges  to  be  impossible  to  God,  So  it  is  clear  that  the 
omnipotence  of  God  does  not  take  away  from  things  their 
impossibility  and  necessity. 

Fourth  Article, 
whether  god  can  make  the  past  not  to  have 

BEEN  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  God  can  make  the  past  not  to 
have  been.  For  what  is  impossible  in  itself  is  much  more 
impossible  than  that  which  is  only  impossible  accidentally. 
But  God  can  do  what  is  impossible  in  itself,  as  to  give  sight 
to  the  blind,  or  to  raise  the  dead.  Therefore,  and  much 
more  can  He  do  what  is  only  impossible  accidentally.  Now 
for  the  past  not  to  have  been  is  impossible  accidentally: 
thus  for  Socrates  not  to  be  running  is  accidentally  impossible, 
from  the  fact  that  his  running  is  a  thing  of  the  past.  There- 
fore God  can  make  the  past  not  to  have  been. 

Obj.  2.  Further,  what  God  could  do.  He  can  do  now, 
since  His  power  is  not  lessened.  But  God  could  have 
effected,  before  Socrates  ran,  that  he  should  not  run. 
I*  23 


Q.  25.  Art.  4    THE  "  SUMMA  THEOLOGICA  " 

Therefore,  when  he  has  run,  God  could  effect  that  he  did 
not  run. 

Ohj.  3.  Further,  charity  is  a  more  excellent  virtue  than 
virginity.  But  God  can  supply  charity  that  is  lost;  there- 
fore also  lost  virginity.  Therefore  He  can  so  effect  that 
what  was  corrupt  should  not  have  been  corrupt. 

On  the  contrary,  Jerome  says  {Ep.  22  ad  Eustoch.) :  Although 
God  can  do  all  things,  He  cannot  make  a  thing  that  is  corrupt 
not  to  have  been  corrupted.  Therefore,  for  the  same  reason. 
He  cannot  effect  that  anything  else  which  is  past  should 
not  have  been. 

/  answer  that,  As  was  said  above  (Q.  VII.,  A.  2),  there  does 
not  fall  under  the  scope  of  God's  omnipotence  anything 
that  implies  a  contradiction.  Now  that  the  past  should 
not  have  been  implies  a  contradiction.  For  as  it  implies 
a  contradiction  to  say  that  Socrates  is  sitting,  and  is  not 
sitting,  so  does  it  to  say  that  he  sat,  and  did  not  sit.  But 
to  say  that  he  did  sit  is  to  say  that  it  happened  in  the  past. 
To  say  that  he  did  not  sit,  is  to  say  that  it  did  not  happen. 
Whence,  that  the  past  should  not  have  been,  does  not  come 
under  the  scope  of  divine  power.  This  is  what  Augustine 
means  when  he  says  (Contra  Faust,  xxix.  5):  Whosoever 
says.  If  God  is  almighty,  let  Him  make  what  is  done  as  if  it 
were  not  done,  does  not  see  that  this  is  to  say:  If  God  is  almighty 
let  Him  effect  that  what  is  true,  by  the  very  fact  that  it  is  true, 
be  false:  and  the  Philosopher  says  (Ethic,  vi.  2):  Of  this  one 
thing  alone  is  God  deprived — namely,  to  make  undone  the 
things  that  have  been  done. 

Reply  Obj.  i.  Although  it  is  impossible  accidentally  for 
the  past  not  to  have  been,  if  one  considers  the  past  thing 
itself,  as,  for  instance,  the  running  of  Socrates;  neverthe- 
less, if  the  past  thing  is  considered  as  past,  that  it  should 
not  have  been  is  impossible,  not  only  in  itself,  but  absolutely 
since  it  impUes  a  contradiction.  Thus,  it  is  more  impossible 
than  the  raising  of  the  dead;  in  which  there  is  nothing  con- 
tradictory, because  this  is  reckoned  impossible  in  reference 
to  some  power,  that  is  to  say,  some  natural  power;  for  such 
impossible  things  do  come  beneath  the  scope  of  divine  power. 


355  THE  POWER  OF  GOD  Q.  25.  Art.  5 

Reply  Obj.  2.  As  God,  in  accordance  with  the  perfection 
of  the  divine  power,  can  do  all  things,  and  yet  some  things 
are  not  subject  to  His  power,  because  they  fall  short  of 
being  possible;  so,  also,  if  we  regard  the  immutabiUty  of  the 
divine  power,  whatever  God  could  do.  He  can  do  now. 
Some  things,  however,  at  one  time  were  in  the  nature  of 
possibility,  whilst  they  were  yet  to  be  done,  which  now  fall 
short  of  the  nature  of  possibiUty,  when  they  have  been  done. 
So  is  God  said  not  to  be  able  to  do  them,  because  they 
themselves  cannot  be  done. 

Reply  Obj.  3.  God  can  remove  all  corruption  of  the  mind 
and  body  from  a  woman  who  has  fallen;  but  the  fact  that 
she  had  been  corrupt  cannot  be  removed  from  her;  as  also 
is  it  impossible  that  the  fact  of  having  sinned  or  of  having 
lost  charity  thereby  can  be  removed  from  the  sinner. 

Fifth  Article, 
whether  god  can  do  what  he  does  not  ? 

We  proceed  thus  to  the  Fifth  Article  : — 

Objection  I.  It  seems  that  God  cannot  do  other  than  what 
He  does.  For  God  cannot  do  what  He  has  not  foreknown 
and  preordained  that  He  would  do.  But  He  neither  fore- 
knew nor  preordained  that  He  would  do  anything  except 
what  He  does.    Therefore  He  cannot  do  except  what  He  does. 

Obj,  2.  Further,  God  can  only  do  what  ought  to  be  done 
and  what  is  right  to  be  done.  But  God  is  not  bound  to  do 
what  He  does  not;  nor  is  it  right  that  He  should  do  what 
He  does  not.     Therefore  He  cannot  do  except  what  he  does. 

Obj.  3.  Further,  God  cannot  do  anything  that  is  not  good 
and  befitting  creation.  But  it  is  not  good  for  creatures  nor 
befitting  them  to  be  otherwise  than  as  they  are.  There- 
fore God  cannot  do  except  what  He  does. 

On  the  contrary,  It  is  said :  Thinkest  thou  that  I  cannot  ask 
My  Father,  and  He  will  give  Me  presently  more  than  twelve 
legions  of  angels  ?  (Matth.  xxvi.  53).  But  He  neither  asked 
for  them,  nor  did  His  Father  show  them  to  refute  the  Jews, 
Therefore  God  can  do  what  He  does  not. 


Q.  25.  Art.  5    THE  "  SUMMA  THEOLOGICA  "  356 

/  answer  that,  In  this  matter  certain  persons  erred  in  two 
ways.  Some  laid  it  down  that  God  acts  from  natural 
necessity  in  such  way  that  as  from  the  action  of  nature 
nothing  else  can  happen  beyond  what  actually  takes  place — 
as,  for  instance,  from  the  seed  of  man,  a  man  must  come,  and 
from  that  of  an  olive,  an  olive ;  so  from  the  divine  operation 
there  could  not  result  other  things,  nor  another  order  of 
things,  than  that  which  now  is.  But  we  showed  above 
(Q.  XIX.,  A.  3)  that  God  does  not  act  from  natural  necessity, 
but  that  His  will  is  the  cause  of  all  things;  nor  is  that  will 
naturally  and  from  any  necessity  determined  to  those  things. 
Whence  in  no  way  at  all  is  the  present  course  of  events  pro- 
duced by  God  from  any  necessity,  so  that  other  things  could 
not  happen.  Others,  however,  said  that  the  divine  power 
is  restricted  to  this  present  course  of  events  through  the 
order  of  the  divine  wisdom  and  justice,  without  which 
God  does  nothing.  But  since  the  power  of  God,  which  is 
His  essence,  is  nothing  else  but  His  wisdom,  it  can  indeed 
be  fittingly  said  that  there  is  nothing  in  the  divine  power 
which  is  not  in  the  order  of  the  divine  wisdom;  for  the 
divine  wisdom  includes  the  whole  potency  of  the  divine 
power.  Yet  the  order  placed  in  creation  by  divine  wisdom,  in 
which  order  the  notion  of  His  j  ustice  consists,  as  said  above 
(Q.  XXL,  A.  2),  is  not  so  adequate  to  the  divine  wisdom 
that  the  divine  wisdom  should  be  restricted  to  this  present 
order  of  things.  Now  it  is  clear  that  the  whole  idea  of  order 
which  a  wise  man  puts  into  things  made  by  him  is  taken 
from  their  end.  So,  when  the  end  is  proportionate  to  the 
things  made  for  that  end,  the  wisdom  of  the  maker  is  re- 
stricted to  some  definite  order.  But  the  divine  goodness 
is  an  end  exceeding  beyond  all  proportion  things  created. 
Whence  the  divine  wisdom  is  not  so  restricted  to  any  par- 
ticular order  that  no  other  course  of  events  could  happen. 
Wherefore  we  must  simply  say  that  God  can  do  other  things 
than  those  He  has  done. 

Reply  Obj,  i.  In  ourselves,  in  whom  power  and  essence 
are  distinct  from  will  and  intellect,  and  again  intellect 
from  wisdom,  and  will  from  justice,  there  can  be  some- 


357  THE  POWER  OF  GOD  Q.  25.  Art.  5 

thing  in  the  power  which  is  not  in  the  just  will  nor  in  the 
wise  intellect.  But  in  God,  power  and  essence,  will  and 
intellect,  wisdom  and  justice,  are  one  and  the  same. 
Whence,  there  can  be  nothing  in  the  divine  power  which 
cannot  also  be  in  His  just  will  or  in  His  wise  intellect. 
Nevertheless,  because  His  will  cannot  be  determined  from 
necessity  to  this  or  that  order  of  things,  except  upon  sup- 
position, as  was  said  above  (Q.  XIX.,  A.  3),  neither  are  the 
wisdom  and  justice  of  God  restricted  to  this  present  order, 
as  was  shown  above ;  so  nothing  prevents  there  being  some- 
thing in  the  divine  power  which  He  does  not  will,  and  which 
is  not  included  in  the  order  which  He  has  placed  in  things. 
Again,  because  power  is  considered  as  executing,  the  will 
as  commanding,  and  the  intellect  and  wisdom  as  directing; 
what  is  attributed  to  His  power  considered  in  itself,  God 
is  said  to  be  able  to  do  in  accordance  with  His  absolute  power. 
Of  such  a  kind  is  everything  which  has  the  nature  of  being, 
as  was  said  above  (A.  3).  What  is,  however,  attributed  to 
the  divine  power,  according  as  it  carries  into  execution  the 
command  of  a  just  will,  God  is  said  to  be  able  to  do  by  His 
ordinary  power.  In  this  manner,  we  must  say  that  God 
can  do  other  things  by  His  absolute  power  than  those  He 
has  foreknown  and  preordained  He  would  do.  But  it  could 
not  happen  that  He  should  do  anything  which  He  had  not 
foreknown,  and  had  not  preordained  that  He  would  do, 
because  His  actual  doing  is  subject  to  His  foreknowledge 
and  preordination,  though  His  power,  which  is  His  nature, 
is  not  so.  For  God  does  things  because  He  wills  so  to  do; 
yet  the  power  to  do  them  does  not  come  from  His  will, 
but  from  His  nature. 

Reply  Ohj.  2.  God  is  bound  to  nobody  but  Himself. 
Hence,  when  it  is  said  that  God  can  only  do  what  He  ought, 
nothing  else  is  meant  by  this  than  that  God  can  do  nothing 
but  what  is  befitting  to  Himself,  and  just.  But  these 
words  befitting  and  just  may  be  understood  in  two  ways: 
one,  in  direct  connection  with  the  verb  is;  and  thus  they 
would  be  restricted  to  the  present  order  of  things;  and  would 
concern  His  power.     Then  what  is  said  in  the  objection  is 


Q.  25.  Art.  6    THE  "  SUMMA  THEOLOGICA  "  358 

false;  for  the  sense  is  that  God  can  do  nothing  except  what 
is  now  fitting  and  just.  If,  however,  they  be  joined  directly 
with  the  verb  can  (which  has  the  e^ect  of  extending  the 
meaning),  and  then  secondly  with  is,  the  present  will  be 
signified,  but  in  a  confused  and  general  way.  The  sentence 
would  then  be  true  in  this  sense:  God  cannot  do  anything 
except  that  which,  if  He  did  it,  would  he  suitable  and  just. 

Reply  Ohj.  3.  Although  this  order  of  things  be  restricted 
to  what  now  exists,  the  divine  power  and  wisdom  are  not 
thus  restricted.  Whence,  although  no  other  order  would 
be  suitable  and  good  to  the  things  which  now  are,  yet 
God  can  do  other  things  and  impose  upon  them  another 
order. 

Sixth  Article, 
whether  god  can  do  better  than  what  he  does  ? 

We  proceed  thus  to  the  Sixth  Article: — 

Objection  i.  It  seems  that  God  cannot  do  better  than  He 
does.  For  whatever  God  does,  He  does  in  a  most  powerful 
and  wise  way.  But  a  thing  is  so  much  the  better  done 
as  it  is  more  powerfully  and  wisely  done.  Therefore  God 
cannot  do  anything  better  than  He  does. 

Ohj.  2.  Further,  Augustine  thus  argues  (Contra  Maximin. 
iii.  8) :  If  God  could,  hut  would  not,  beget  a  Son  His  equal, 
He  would  have  been  envious.  For  the  same  reason,  if  God 
could  have  made  better  things  than  He  has  done,  but  was 
not  willing  so  to  do.  He  would  have  been  envious.  But 
envy  is  far  removed  from  God.  Therefore  God  makes 
everything  of  the  best.  He  cannot  therefore  make  any- 
thing better  than  He  does. 

Obj.  3.  Further,  what  is  very  good  and  the  best  of  all 
cannot  be  bettered;  because  nothing  is  better  than  the  best. 
But  as  Augustine  says  (Enchir.  10),  each  thing  that  God  has 
made  is  good,  and,  taken  all  together  they  are  very  good;  because 
in  them  all  consists  the  wondrous  beauty  of  the  universe. 
Therefore  the  good  in  the  universe  could  not  be  made  better 
by  God. 

Ohj.  4.  Further,  Christ  as  man  is  full  of  grace  and  truth. 


359  THE  POWER  OF  GOD  Q.  25.  Art.  6 

and  has  the  Spirit  without  measure;  and  so  He  cannot  be 
better.  Again  created  happiness  is  described  as  the  highest 
good,  and  thus  could  not  be  better.  And  the  Blessed  Virgin 
Mary  is  raised  above  all  the  choirs  of  angels,  and  so  cannot 
be  better  than  she  is.  God  cannot  therefore  make  all  things 
better  than  He  has  made  them. 

On  the  contrary,  It  is  said  (Eph.  iii.  20) :  God  is  able  to  do 
all  things  more  abundantly  than  we  desire  or  understand. 

I  answer  that,  The  goodness  of  anything  is  twofold;  one, 
which  is  of  the  essence  of  it — ^thus,  for  instance,  to  be  rational 
pertains  to  the  essence  of  man.  As  regards  this  good,  God 
cannot  make  a  thing  better  than  it  is  itself;  although  He 
can  make  another  thing  better  than  it ;  even  as  He  cannot 
make  the  number  four  greater  than  it  is ;  because  if  it  were 
greater  it  would  no  longer  be  four,  but  another  number. 
For  the  addition  of  a  substantial  difference  in  definitions 
is  after  the  manner  of  the  addition  of  unity  in  numbers 
{Metaph.  viii.  10).  Another  kind  of  goodness  is  that  which 
is  over  and  above  the  essence;  thus,  the  good  of  a  man  is 
to  be  virtuous  or  wise.  As  regards  this  kind  of  goodness, 
God  can  make  better  the  things  He  has  made.  Absolutely 
speaking,  however,  God  can  make  something  else  better 
than  each  thing  made  by  Him. 

Reply  Obj.  i.  When  it  is  said  that  God  can  make  a  thing 
better  than  He  makes  it,  if  better  is  taken  substantively, 
this  proposition  is  true.  For  He  can  always  make  something 
else  better  than  each  individual  thing:  and  He  can  make 
the  same  thing  in  one  way  better  than  it  is,  and  in  another 
way  not;  as  was  explained  above.  If,  however,  better  is 
taken  as  an  adverb,  implying  the  manner  of  the  making; 
thus  God  cannot  make  anything  better  than  He  makes  it, 
because  He  cannot  make  it  from  greater  wisdom  and  good- 
ness. But  if  it  implies  the  manner  of  the  thing  done.  He  can 
make  something  better;  because  He  can  give  to  things 
made  by  Him  a  better  manner  of  existence  as  regards  the 
accidents,  although  not  as  regards  the  substance. 

Reply  Obj.  2.  It  is  of  the  nature  of  a  son  that  he  should 
be  equal  to  his  father,  when  he  comes  to  maturity.     But 


Q.  25.  Art.  6    THE  ''  SUMMA  THEOLOGICA  "  360 

it  is  not  of  the  nature  of  anything  created,  that  it  should 
be  better  than  it  was  made  by  God.  Hence  the  comparison 
fails. 

Reply  Ohj.  3.  The  universe,  the  present  creation  being 
supposed,  cannot  be  better,  on  account  of  the  most  beautiful 
order  given  to  things  by  God;  in  which  the  good  of  the 
universe  consists.  For  if  any  one  thing  were  bettered,  the 
proportion  of  order  would  be  destroyed;  as  if  one  string 
were  stretched  more  than  it  ought  to  be,  the  melody  of  the 
harp  would  be  destroyed.  Yet  God  could  make  other 
things,  or  add  something  to  the  present  creation;  and  then 
there  would  be  another  and  a  better  universe. 

Reply  Ohj.  4.  The  humanity  of  Christ,  from  the  fact 
that  it  is  united  to  the  Godhead;  and  created  happiness 
from  the  fact  that  it  is  the  fruition  of  God ;  and  the  Blessed 
Virgin  from  the  fact  that  she  is  the  mother  of  God;  have 
all  a  certain  infinite  dignity  from  the  infinite  good,  which  is 
God.  And  on  this  account  there  cannot  be  anything  better 
than  these;  just  as  there  cannot  be  anything  better  than 
God. 


QUESTION  XXVI. 

OF  THE  DIVINE  BEATITUDE. 
{In  Four  Articles.) 

After  considering  all  that  pertains  to  the  unity  of  the 
divine  essence,  we  come  to  treat  of  the  divine  beatitude. 
Concerning  this,  there  are  four  points  of  inquiry :  (i)  Whether 
beatitude  belongs  to  God  ?  (2)  In  regard  to  what  is  God 
called  blessed;  does  this  regard  His  act  of  intellect  ? 
(3)  Whether  He  is  essentially  the  beatitude  of  each  of  the 
blessed  ?  (4)  Whether  all  other  beatitude  is  included  in 
the  divine  beatitude  ? 

First  Article, 
whether  beatitude  belongs  to  god  ? 

We  proceed  thus  to  the  First  Article: — 

Objection  i.  It  seems  that  beatitude  does  not  belong  to 
God.  For  beatitude  according  to  Boethius  [De  consol.  iv.) 
is  a  state  made  perfect  by  the  aggregation  of  all  good  things. 
But  aggregation  of  goods  has  no  place  in  God;  nor  has 
composition.     Therefore  beatitude  does  not  belong  to  God. 

Obj.  2.  Further,  Beatitude  or  happiness  is  the  reward  of 
virtue,  according  to  the  Philosopher  (Ethic,  i.  9).  But  reward 
does  not  apply  to  God;  as  neither  does  merit.  Therefore 
neither  does  beatitude. 

On  the  contrary,  The  Apostle  says :  Which  in  His  times 
He  shall  show,  who  is  the  Blessed  and  only  Mighty,  the  King 
of  Kings  and  Lord  of  Lords  (i  Tim.  vi.  15). 

I  answer  that.  Beatitude  belongs  to  God  in  a  very  special 
manner.  For  nothing  else  is  understood  to  be  meant  by 
the  term  beatitude  than  the  perfect  good  of  an  intellectual 

361 


Q.  26.  Art.  2    THE  "  SUMMA  THEOLOGIGA  "  362 

nature ;  which  is  capable  of  knowing  that  it  has  a  sufficiency 
of  the  good  which  it  possesses,  to  which  it  is  competent 
that  good  or  ill  may  befall,  and  which  can  control  its  own 
actions.  All  of  these  things  belong  in  a  most  excellent 
manner  to  God — namely,  to  be  perfect,  and  to  possess  in- 
telligence. Whence  beatitude  belongs  to  God  in  the  highest 
degree. 

Reply  Ohj.  i.  Aggregation  of  good  is  in  God,  after  the 
manner  not  of  composition,  but  of  simplicity;  for  those 
things  which  in  creatures  are  manifold,  pre-exist  in  God, 
as  was  said  above  (QQ.  IV.,  A.  3;  XI 1 1.,  A.  4),  in  simplicity 
and  unity. 

Reply  Ohj.  2.  It  belongs  as  an  accident  to  beatitude  or 
happiness  to  be  the  reward  of  virtue,  so  far  as  anyone  attains 
to  beatitude;  even  as  to  be  the  term  of  generation  belongs 
accidentally  to  a  being,  so  far  as  it  passes  from  potentiality 
to  act.  As,  then,  God  has  being,  though  not  begotten;  so 
He  has  beatitude,  although  not  acquired  by  merit. 

I 

Second  Article. 

whether  god  is  caixed  blessed  in  respect  of 
his  intellect  ? 

We  proceed  thus  to  the  Second  Article : — 

Objection  i.  It  seems  that  God  is  not  called  blessed  in 
respect  of  His  intellect.  For  beatitude  is  the  highest  good. 
But  good  is  said  to  be  in  God  in  regard  to  His  essence, 
because  good  has  reference  to  being  which  is  according 
to  essence,  according  to  Boethius  {De  hehdom.).  Therefore 
beatitude  also  is  said  to  be  in  God  in  regard  to  His  essence, 
and  not  to  His  intellect. 

Ohj.  2.  Further,  Beatitude  implies  the  notion  of  end. 
Now  the  end  is  the  object  of  the  will,  as  also  is  the  good. 
Therefore  beatitude  is  said  to  be  in  God  with  reference  to 
His  will,  and  not  with  reference  to  His  intellect. 

On  the  contrary,  Gregory  says  [Moral,  xxxii.  7) :  He  is  in 
glory,  Who  whilst  He  rejoices  in  Himself,  needs  not  further 
praise.     To  be  in  glory,  however,  is  the  same  as  to  be  blessed. 


363  THE  DIVINE  BEATITUDE       Q.  26.  Art.  3 

Therefore,  since  we  enjoy  God  in  respect  of  our  intellect, 
because  vision  is  the  whole  of  the  reward,  as  Augustine 
says  {De  Civ.  Dei  xxii.),  it  would  seem  that  beatitude  is 
said  to  be  in  God  in  respect  of  His  intellect. 

I  answer  that,  Beatitude,  as  stated  above  (A.  i),  is  the  perfect 
good  of  an  intellectual  nature.  Thus  it  is  that,  as  everything 
desires  the  perfection  of  its  nature,  intellectual  nature  desires 
naturally  to  be  happj^  Now  that  which  is  most  perfect 
in  any  intellectual  nature  is  the  intellectual  operation, 
by  which  in  some  sense  it  grasps  everything.  Whence  the 
beatitude  of  every  intellectual  nature  consists  in  understand- 
ing. Now  in  God,  to  be  and  to  understand  are  one  and  the 
same  thing;  differing  only  in  the  manner  of  our  understanding 
them.  Beatitude  must  therefore  be  assigned  to  God  in 
respect  of  His  intellect;  as  also  to  the  blessed,  who  are 
called  blessed  {heati)  by  reason  of  the  assimilation  to  His 
beatitude. 

Reply  Ohj.  i.  This  argument  proves  that  beatitude  belongs 
to  God;  not  that  beatitude  pertains  essentially  to  Him 
under  the  aspect  of  His  essence ;  but  rather  under  the  aspect 
of  His  intellect. 

Reply  Ohj.  2.  Since  beatitude  is  a  good,  it  is  the  object  of 
the  will;  now  the  object  is  understood  as  prior  to  the  act 
of  a  power.  Whence  in  our  manner  of  understanding, 
divine  beatitude  precedes  the  act  of  the  will  at  rest  in  it. 
This  cannot  be  other  than  the  act  of  the  intellect ;  and  thus 
beatitude  is  to  be  found  in  an  act  of  the  intellect. 


Third  Article, 
whether  god  is  the  beatitude  of  each  of  the 

BLESSED  ? 

We  proceed  thus  to  the  Third  Article: — 

Objection  i.  It  seems  that  God  is  the  beatitude  of  each 
of  the  blessed.  For  God  is  the  supreme  good,  as  was  said 
above  (Q.  VI.,  AA.  2,  4).  But  it  is  quite  impossible  that 
there  should  be  many  supreme  goods,  as  also  is  clear  from 
what  has  been  said  above  (Q.  XL,  A.  3).     Therefore,  since 


g.  26.  Art.  3    THE  *'  SUMMA  THEOLOGICA  "  364 

it  is  of  the  essence  of  beatitude  that  it  should  be  the 
supreme  good,  it  seems  that  beatitude  is  nothing  else  but 
God  Himself. 

Ohj.  2.  Further,  Beatitude  is  the  last  end  of  the  rational 
nature.  But  to  be  the  last  end  of  the  rational  nature  belongs 
only  to  God.  Therefore  the  beatitude  of  every  blessed  is 
God  alone. 

On  the  co7ityary,  The  beatitude  of  one  is  greater  than 
that  of  another,  according  to  i  Cor.  xv.  41 :  Star  differ eth 
from  star  in  glory.  But  nothing  is  greater  than  God.  There- 
fore beatitude  is  something  different  from  God. 

/  answer  that,  The  beatitude  of  an  intellectual  nature 
consists  in  an  act  of  the  intellect.  In  this  we  may  consider 
two  things — namely,  the  object  of  the  act,  which  is  the  thing 
understood;  and  the  act  itself,  which  is  to  understand. 
If,  then,  beatitude  be  considered  on  the  side  of  the  object, 
God  is  the  only  beatitude;  for  everyone  is  blessed  from 
this  sole  fact,  that  he  understands  God,  in  accordance  with 
the  saying  of  Augustine  {Conf.  v.  4):  Blessed  is  he  who 
knoweth  Thee,  though  he  know  nought  else.  But  as  regards 
the  act  of  understanding,  beatitude  is  a  created  thing  in 
beatified  creatures;  but  in  God,  even  in  this  way,  it  is  an 
uncreated  thing. 

Reply  Ohj.  i.  Beatitude,  as  regards  its  object,  is  the 
supreme  good  absolutely,  but  as  regards  its  act,  in  beatified 
creatures  it  is  their  supreme  good,  not  absolutely,  but  in 
that  kind  of  goods  which  a  creature  can  participate. 

Reply  Ohj.  2.  End  is  twofold  namely,  ohjective  and 
suhjective,  as  the  Philosopher  says  {Greater  Ethics,  i.  3), 
namely,  the  thing  itself  a.nd  its  use.  Thus  to  a  miser  the  end 
is  money,  and  its  acquisition.  Accordingly  God  is  indeed 
the  last  end  of  a  rational  creature,  as  the  thing  itself;  but 
created  beatitude  is  the  end,  as  the  use,  or  rather  fruition, 
of  the  thing. 


365  THE  DIVINE  BEATITUDE       Q.  26.  Art.  4 


Fourth  Article. 

whether  all  other  beatitude  is  included  in  the 
beatitude  of  god  ? 

We  proceed  thus  to  the  Fourth  Article  : — 

Objection  i.  It  seems  that  the  divine  beatitude  does  not 
embrace  all  other  beatitudes.  For  there  are  some  false 
beatitudes.  But  nothing  false  can  be  in  God.  Therefore 
the  divine  beatitude  does  not  embrace  all  other  beatitudes. 

Obj.  2.  Further,  a  certain  beatitude,  according  to  some, 
consists  in  things  corporeal;  as  in  pleasure,  riches,  and  such 
like.  Now  none  of  these  have  to  do  with  God,  since  He  is 
incorporeal.  Therefore  His  beatitude  does  not  embrace 
all  other  beatitudes. 

On  the  contrary,  Beatitude  is  a  certain  perfection.  But 
the  divine  perfection  embraces  all  other  perfection,  as  was 
shown  above  (Q.  IV.,  A.  2.).  Therefore  the  divine  beatitude 
embraces  all  other  beatitudes. 

/  answer  that,  Whatever  is  desirable  in  whatsoever  beati- 
tude, whether  true  or  false,  pre-exists  wholly  and  in  a  more 
eminent  degree  in  the  divine  beatitude.  As  to  contempla- 
tive happiness,  God  possesses  a  continual  and  most  certain 
contemplation  of  Himself  and  of  all  things  else;  and  as  to 
that  which  is  active,  he  has  the  governance  of  the  whole 
universe.  As  to  earthly  happiness,  which  consists  in 
delight,  riches,  power,  dignity,  and  fame,  according  to 
Boethius  (De  Consol.  iii.  10),  He  possesses  joy  in  Himself 
and  all  things  else  for  His  delight ;  instead  of  riches  He  has 
that  complete  self-sufficiency,  which  is  promised  by  riches; 
in  place  of  power,  He  has  omnipotence;  for  dignities,  the 
government  of  all  things;  and  in  place  of  fame.  He  possesses 
the  admiration  of  all  creatures. 

Reply  Obj.  i.  A  particular  kind  of  beatitude  is  false 
according  as  it  falls  short  of  the  idea  of  true  beatitude; 
and  thus  it  is  not  in  God.  But  whatever  semblance  it  has, 
howsoever  slight,  of  beatitude,  the  whole  of  it  pre-exists 
in  the  divine  beatitude. 


Q.  26.  Art.  4    THE  "  SUMMA  THEOLOGICA  '*  366 

Reply  Ohj.  2.  The  good  that  exists  in  things  corporeal 
in  a  corporeal  manner,  is  also  in  God,  but  in  a  spiritual 
manner. 

We  have  now  spoken  enough  concerning  what  pertains 
to  the  unity  of  the  divine  essence.
