PREFACE. 

THE first English edition of this treatise appeared in 1882 
under the title of " Aristotle's Psychology in Greek and 
English, with Introduction and Notes by Edwin Wallace." It 
has been for some time out of print and, if Mr Wallace had 
survived to see his work through a second edition, he would 
probably have made considerable alterations, owing to the re- 
searches of the last quarter of a century. Of these I resolved 
to make full use, when, with their accustomed liberality, the 
Syndics of the Cambridge University Press accepted my offer 
to prepare an independent edition. Among the fresh materials 
which have accumulated, two are of special importance : I mean, 
the critical edition of De Anima by the late Wilhelm Biehl and 
the series of Aristotelian commentaries re-edited under the 
auspices of the Berlin Academy. As regards the text, I have 
seldom had reason to deviate from Biehl's conclusions, but in my 
critical notes, which are based on his judicious selection, I have 
gone further than he did in referring to, or occasionally citing 
from, authorities. The interval of time has enabled me to cite 
with greater uniformity than Biehl could do from the Berlin 
editions of the Greek commentators. I have followed the example 
of Wallace in printing an English version opposite the Greek text 
A century ago, perhaps, the Latin of Argyropylus with the 
necessary alterations would have served the same purpose by 
indicating the construction of the sentences and the minimum 
of supplement needed to make sense and grammar of Aristotle's 
shorthand style. But fashions have changed. The terse sim- 
plicity, not to say baldness, of literal Latin is now discarded for 
that rendering into a modern vernacular which, whatever its 
advantages, is always in danger of becoming, and too often is, 
a mere medley of specious paraphrase and allusive subterfuge. In 
compiling my notes I have drawn freely upon all my predecessors, 
not only on the Greeks themselves, who even in their decline were 
excellent paraphrasts, but also on modern editors and translators, 
from Paeius and Trendelenburg onward ; while through Zabarella 
I have made some slight acquaintance with the views of the Latin 



viii PREFA CE 

schoolmen. Among modern critics few have the great gifts of 
Torstrik, who by his insight, candour and logic contributed beyond 
all others to improve Bekker's text of the treatise. Of this 
distinction nothing can rob him : haeret capiti cum multa laudc 
corona. In matters of punctuation and orthography I have taken 
my own line, but, lest I should be accused of inconsistency, I must 
add that when citing from other editions I have been scrupulous 
in preserving their peculiarities. Thus, while for my o\vn part 
I admit indifferently alel and dei, tyLyveo-Bat, and ywe&daf,, when 
I cite the Metaphysics from Christ, I follow him in always 
preferring alel and <yL<yve<r6ai, to the exclusion of del and ryLr<r8ai<. 
Again, though I regard %<$ov and pe^ei/crat, as alone correct, in 
citing from other editions where %S>ov and fjue^ttcrat are printed 
I have been careful not to alter the spelling. In references to the 
Metaphysics^ Ethics and Politics I have been content to t^ive 
Bekker's page, column and line without the addition of book 
and chapter, thus avoiding the confusion which arises from the 
double numbering of certain books and chapters. I have tried 
as far as possible to give in the notes the reasons for my 
conclusions, so that where I have erred it will be more easy for 
my critics to refute me. My own claims to originality are modest 
enough. In fact, in a subject like this, absolute novelty of view is 
almost unattainable, perhaps undesirable. 

I am indebted to Professor Henry Jackson, to whom the work 
is dedicated, for permission to publish sundry proposals, chiefly 
textual, taken from his public lectures delivered in the year 1903. 
Mr F. M. Cornford kindly placed at my disposal for this edition 
various notes on the third Book, which, after I had made use of 
them, were communicated to the Cambridge Philological Society. 
My book has profited by the vigilance and insight of several 
friends, to whom I desire to make fitting acknowledgment. In 
particular, Miss Margaret Alford, Lecturer of Bedford College, 
revised for me the first draft of the notes and added to them much 
of value. Nor must I pass over the good offices of Dr T. L. Heath, 
who assisted in correcting the proof-sheets, or those of the Rev. 
J. M. Schulhof, who aided me five years ago at the commencement 
of my task. Lastly, I must express very great obligations to the 
staff of the University Press, including their accomplished readers, 
for their able and zealous co-operation,

external soul, on which the life of the individual depends, plays the 
same part as in the folk-lore of savages to-day 1 . The opening lines 
of the Iliad &r&w a sharp distinction between the heroes themselves, 
left a prey for dogs and vultures, and their souls, sent down to 
Hades or the invisible world. The ghost of Patroclus, which 
appears to Achilles in a dream, is an emaciated, enfeebled shadow, 
deprived of all its strength by severance from the body, which was 
the real man. In the underworld these pale, ineffectual ghosts arc 
much alike in general condition. Apart from a few notorious 
offenders punished for their misdeeds, they pursue the shadows of 
their former avocations. Whether in Greek language and thought 
two separate conceptions are blended, whether the sum of the 
intellectual and moral qualities was associated at one time with 
the blood and at another with the breath, whether the breath of life 
superseded an older smoke-soul, the exhalation arising from spilt 
blood, and whether these two conceptions were connected with the 
practices of inhumation and cremation respectively, are matters of 
speculation on which it is hardly possible to arrive at a definite 
conclusion 2 . When we pass from Homer to later poets we find the 
same primitive beliefs variously modified. In Hesiod the heroes 
go no longer to the underworld, but to the Isles of the Blest, and 
ancestral spirits have developed into " daemons " exerting a benefi- 
cent influence on their descendants . From the dirges of Pindar 
we have two important fragments 4 . One is a glowing picture of 
the lot of the happy dead. In the other we are told that, " while 
the body of every man folio weth after mighty death, there still 
liveth a likeness of his prime which alone is of divine origin, which 
slumbereth so long as the limbs are busy, but full oft in dreams 
showeth to sleepers the issue that draweth near of pleasant things 
and cruel." 

In the Orphic and Pythagorean brotherhoods the primitive 
Orphic beliefs were moulded into a thoroughgoing doctrine 

doctrine. of transmigration. Three main conceptions underlie 

Orphic asceticism. First, there is the opposition between body and 
soul. The soul is better than the body and is buried in the body 
for its sins, the body is its temporary prison. Next comes the 
necessity for a purification of the soul. All evil is followed by

retribution. Through abstinence and penance alone may the soul 
hope to regain its former blissful state. Thirdly, there is the long 
series of incarnations in which, according to their deeds during a 
former existence, souls take a higher or a lower place in human or 
animal bodies or even in plants 1 . Though these ideas occupy so 
small a place in literature, they are clearly very old, for the extant 
burlesque of Xenophanes 2 attests the acceptance of metempsychosis 
by Pythagoras, and all probability points to his having derived 
it from the still older Orphic sect. At Athens the Eleusinian 
mysteries, at which some such ideas were symbolically inculcated, 
were under the patronage of the state ; but nevertheless the belief 
in an after life in the underworld, as set forth by Homer, for the 
most part maintained its hold upon the ordinary educated citizen. 

I-ittle is to be learned from the Ionian thinkers, whom 
Ionian Aristotle calls physicists or physiologists 3 . In the 

physicists. dawn of enquiries which, strictly speaking, were 

rather scientific than philosophical, men sought to explain to 
themselves of what things were constituted and how they had come 
into their present condition. Their problem, we should now say, 
was the constitution of matter and, if occasionally, when they found 
the primary element in air or fire or some other body, they also 
declared that this was the cause of vital functions, it was merely a 
corollary to their general doctrine and of no special importance. 
The subjects on which we find hints are the substance of the soul, 
the distinction between its various powers, and the nature of 
knowledge. So far as the substance of the individual soul was 
identical with, or a product of, the universal element, they all 
agreed in regarding it as not immaterial, but of an extremely 
refined and mobile materiality. The soul was credited with the 
power to know and perceive, as well as the power to move the body. 
Heraclitus, who had grasped the flux of matter in 

Hemclitus, . , . , , , . , , , 

constant circulation, held it to be governed by an 
universal law. Knowledge to him consists in apprehending this law. 
In comparison with such knowledge he deprecated the evidence of 
sense: eyes and ears are better than the other senses, but are 
bad witnesses, if the soul does not understand. Meanwhile in 
the West other schools of philosophy had arisen, the Eleatic and

Parmenides derived the intelligence of man from the

composition and elementary mixture of his bodily 
parts, heat and cold being the elements of things 1 . The pre- 
ponderant element characterises the thought of the individual man. 
But the chief legacy of Parmenides to his successors was his 
doctrine of the one immutable Being, which alone satisfies the 
requirements of an object of knowledge. The element of the 
lonians did not satisfy these conditions, being endowed with the 
power to pass from one condition to another, whether intermittently 
or perpetually. Nothing, according to Parmenides, is ever generated 
or destroyed, however varied its manifestations and the changes it 
presents to the senses. On the foundation thus laid by Pannenides 
Empedocles, Anaxagoras and Leucippus constructed their systems, 
resolving apparent generation and destruction into combination 
and separation of primary elements or principles, themselves 
indestructible. They differed, Aristotle remarks, as to the number 
and nature of these indestructible elements 2 . Empedocles made a 
mistake in accepting a crude popular analysis into air, earth, fire and 
water, elements which do not so much as correspond to a rough divi- 
sion of matter into the solid, liquid and gaseous states. Anaxagoras, 
with his homoeomeries, was in our view still wider of the mark. 
Leucippus and Democritus at last found in the atoms a working 
hypothesis of the constitution of matter, which has lasted down to 
the present day. It is these three physical systems which most 
profoundly influenced Aristotle. He unfortunately accepted the first 
with modifications and opposed the last, by the merits of which he 
was nevertheless profoundly impressed. Each of these thrc k e systems 
took up the problem of the soul. But in the meantime medical 
enquiries had been actively prosecuted, and it is to a Pythaffo- 
rean ' Alcmaeon f Croton, that we owe the earliest 
advances towards the physiology of the senses. He 
was the first to recognise the brain as the central organ of 
intellectual activity. He dissected animals and by this means 
discovered the chief nerves of sense, which, like Aristotle, he called 
" conduits" or " channels," and he traced them to their termination in 
the brain. Deafness and blindness he held to be caused when by a 
concussion the brain was shifted out of its normal position and the 
channels of hearing and seeing respectively were thus blocked. He 
submitted the several senses to a searching examination, starting

with the anatomical construction of the sense-organ. The air in 
the ear he regarded as a sounding-board, and he attributed to the 
moisture, softness, flexibility and warmth of the tongue its capacity 
to reduce solid bodies to fluid as a necessary preliminary to tasting. 
He noticed the phenomenon which we call seeing sparks when the 
eye has received a heavy blow, and this suggested a crude theory 
of vision, postulating fire in the eye, a mistake repeated by Em- 
pedocles and by Plato. But it is with the glittering or transparent 
element of water in the eye that it sees, and it sees better according 
to the purity of the element. Vision is effected by the image of the 
thing seen and by the rays which issue from the eye within and 
pass outwards through the water. He derived memory from sense- 
perception and opinion from memory ; from memory and opinion 
combined he derived reason, which distinguishes men from the 
lower animals 1 . What scanty information we have about him 
comes chiefly from Theophrastus 2 , but it would be a great mistake 
to acquiesce in Aristotle's neglect of him. He is only once 
mentioned in De Anima^^ as having held that soul is immortal, on 
the singular ground that by its incessant motion it resembles the 
heavenly bodies, which he also held to be immortal. 

In Empedocles we are dealing not with a sober physical 

enquirer, but with a religious enthusiast and poet-philosopher. He 

accepted the transmigration of souls in a slightly 

Empedocles. , , ,. , . , , ,, , 

altered form ; he introduced wicked as well as good 
" daemons/ 7 condemned for their sins to wander for 10,000 years and 
to become souls of plants, beasts and men. In the course of their 
purification they become prophets, poets, physicians, princes, and 
again return to the gods 4 . Sensation in general he explained by 
the action of like upon like. Particles emanate from external 
bodies and enter our bodies by channels or pores. They cannot 
enter unless there is a certain proportion 3 between the emanation 
and the size and shape of the channel which is to receive it. Thus 
a sense-organ is a particular part of the body which, possessing 
channels of a certain size and shape, is adapted to receive 
emanations of a certain kind, of flavour, odour or sound. But his 
theory of vision was more complicated. Not only are there

emanations from visible objects, but there are also emanations from 
the eye. To this he was led by the analogy of the dark lantern, of 
which the camera obscura furnishes a modern illustration. The 
transparent plates of horn or linen in the lantern, made to protect 
the flame from the wind which might otherwise extinguish it, 
correspond to the thin coats or films in the eye covering the pupil, 
whose contents are partly of a fiery, partly of a watery, nature. 
From the pupil fiery and watery emanations leap forth through 
funnel-shaped channels to meet the fiery and watery emanations 
coming, the one from light, the other from dark* objects outside. 
The principle of "like by like" accounts for the mutual attraction 
of similar materials and their meeting, and, when the two sets of 
emanations meet, vision takes place. The preponderance of water 
or fire in the eye accounts for the fact that some animals see better 
in the dark, others in the daylight 1 . Thus, then, we perceive like 
by like, the four elements of all things, air, earth, fire and water, 
outside, because air, earth, fire and water are present in our bodies s 
Blood is the most perfect mixture of these four elements and to 
this blood where it is purest, viz. about the heart, ho attributed 
thought. As we see earth by earth which is in us* water by water, 
so we think by means of blood, the bodily tissue in which all four 
elements are most perfectly blended. Knipeclocles, then, con- 
sistently confined his attention to the bodily process. The mental 
or psychical state is either ignored in his explanation or reduced to 
its physical conditions. Yet on the problem of knowledges aware 
of the imperfection of the senses, he counsels us to withdraw our 
trust from them and prefer the guidance of reason* 

Anaxagoras distinguished sensation from intflHjft'iice and, 
whereas most of the Prc-Socratics agreed that we 

. - . , ,. ... .. ., 

perceive things by having within us something like 
them, he held that we perceive in virtue of the presence within us 
of something opposite to the thing perceived 3 . Knowledge is not 
to be gained from the senses, because their powers* cannot dis- 
criminate minute changes; while the reactionary physics which he 
propounded involved the presence in every sensible object of 
infinitesimal particles perceptible only in the ajfgre${ato and f 
blended with these, alien particles altogether imperceptible, because 
infinitesimal. Over against this infinity of homoeomeries he set

the other constituent of the universe, which alone is pure and 
unmixed and has nothing in common with anything else. This is 
Nous 1 . The part it played was to communicate the first impulse 
to that rotatory motion which ultimately evolved from the chaos in 
which all things were mixed the present order and regularity of 
the universe. Nous is in all living beings, great and small, in 
varying degrees. It governs and orders and knows. We fortu- 
nately possess the account which Anaxagoras himself gave of Nous, 
and upon the evidence the reader must decide for himself what was 
its nature 2 . Plato and Aristotle construed it as immaterial reason 
and censured the philosopher for not making more thoroughgoing 
use of its mighty agency. Returning now to sense, the contrast 
necessary to perception Anaxagoras found most clearly in touch, 
for our perception of temperature depends upon contrast. We 
know the taste of sweet and bitter only by contrast. Seeing, 
again, takes place by the reflection of an image in the pupil, but in 
a part of it which is of a different colour from the object seen. 
Eyes that see in the daytime are, generally speaking, dark, while 
animals with gleaming eyes see better by night. 

In the Atomists the tendencies of earlier Greek thinkers reach 
t-eucippus mature development. The problem hitherto had been 

Dtfn,c..i.iu*. to determine what matter is, and Leucippus pro- 
pounded a working hypothesis which has ever since been sufficient 
for the purposes of science. Though this theory is derived from 
sense, it departs very widely from the evidence of the senses. 
Knowledge, said Democritus, is of two kinds, genuine knowledge 
that there are atoms and void and nothing else, and knowledge 
which is dark or obscure, by which he meant the information given 
by the senses*. The existence of void apparently contradicts obser- 
vation, experiment fails even now to obtain an absolute void. The 
properties of body are all given by sense. The Atomists accepted 
the evidence of sense for resistance, extension and weight (perhaps 
Democritus was unaware of this last quality), but rejected it for 
colours, sounds, odours and flavours. Out of impenetrable atoms 
of different shapes and sizes the whole universe is built up, and the 
different qualities in things are due either to difference of shape or 
size, or to different arrangements, of the atoms composing them 4 . 
The soul is no exception. It is a complex of atoms within the

body. Soul-atoms are spherical in shape, extremely minute and 
mobile. They resemble the atoms of fire 1 . In thus postulating a 
body within the body to account for vital and intellectual functions, 
Democritus reverts more consistently and systematically than any 
previous philosopher to the standpoint of the savage who, when he 
sees an animal move, is unable to explain the fact except by 
supposing" that there is a little animal inside to move htm. But 
there is this difference, that the little animal is imagined to be ulivc, 
the soul-atoms of Democritus are mere matter*. Tints to push the 
implicit assumptions of their predecessors to their logical con* 
sequences and make the half-conscious hylozoism of the early 
lonians blossom forth in materialism is the jjreat merit of 
Leucippus and Democritus. All processes of sensation* then, are 
instances of the contact 3 between bodies. They are caused by 
"idols" or films which are constantly streaming off from the 
surface of bodies, of inconceivable thinness, yet preserving the 
relative shape of the parts. So far this agrees with Knipcdoclrs ; 
but the latter made his emanations enter the body through chan- 
nels, while the Atomists conceived them as entering by the void 
between the atoms. The same explanation would apply to thought, 
which is excited when the material image of an object enters the 
equally material mind. All the senses are thus but modifications 
of touch. This was made out satisfactorily for taste, and 
Democritus attempted to determine the shapes of the atoms which 
produce the different varieties of taste 4 . Things made of atoms 
angular, winding, small and thin, have an acid taste, those whose 
atoms are spherical and not too small taste sweet, and so cm. His 
four simple colours, white, black, red and green, are accounted for 
by the shape and disposition of atoms, but a similar analysts was 
not attempted for the objects of sound and smell. 

In marked contrast with the attempts which the Atomists and 
of even Empedocles made to bring physics and physio- 
i gy j nto s hape is the retrograde system of Diogenes 
of Apollonia, whose fantastic absurdities have been immortalised 
for us by Aristophanes, He was not satisfied with the resolution 
by Anaxagoras, himself a reactionary in physics, of bodies into 
infinitesimal particles possessing definite qualities, though he was

more attracted by the supposition of unmixed Nous, which is the 
seat of intelligence. But he supplemented this theory by reverting 
to the position of the lonians, one of whom, Anaximenes, had 
chosen air for his primary element. Diogenes endowed air with 
sentience and intelligence. "All creatures," he says, "live and 
see and hear by the same thing " (viz. air), " and from the same 
thing all derive their intelligence as well 1 ." He thus made the 
air in us play an important part in the processes of perception 
and thought. From Alcmaeon he must have borrowed the idea 
that the brain is the central organ ; the air in the sense-organs, 
the eye, the ear, the nostrils, transmitted the impression to the 
air in or near the brain. The common view that seeing takes 
place by the reflection of an image in the pupil he supplemented 
by postulating that this image must be blended with the internal 
air ; otherwise, though the image is formed, there is no seeing. 
He pointed to the fact that, when the optic nerve is inflamed, 
blindness ensues because, as he thought, the admixture with the 
internal air is prevented. His account of hearing may be cited 
for the likeness it bears to that given in DeAnima. "The animals 
which hear most acutely have slender veins, the orifice of the ear 
(like that of the nose) being in them short, slender and straight, 
and the external ear erect and large. For movement of the air in 
the ears sets in motion the internal air" [in or near the brain], 
" Whereas, if the orifice be too wide, the movement of the air in 
the ears causes a ringing in them, and what is heard is indistinct 
noise, because the air upon which the audible sound impinges is 
not at rest 9 ." 

In the fifth century the evolution of successive systems came 
to a halt. The progress of enquiry had been marked by the 
foundation of new sciences like geometry and astronomy, both in 
a flourishing condition, and new arts, like rhetoric and dialectic. 
The bustle and unrest of the times was attended by a growing 
mistrust, not only of the old traditional religious and moral beliefs, 
but of the bewildering intellectual movement which in so short a 
space of time had put forward so many brilliant and contradictory 
speculations. The professional educators, whom we know as the 
Sophists, turned as a rule to practical interests and made human- 
ism, literary criticism, erudition their main themes. 
Protagoras, the greatest of them, adopted a sceptical

attitude and maintained that man was the measure of all things, 
which, as interpreted by Plato, means that, as things appear to mc f 
so they are to me, or the denial of objective truth. There were 
many sceptical currents in the sea of speculation on which Greece 
had embarked. The followers of Hcraclitus pushed the doctrine of 
flux to an extreme. Things never are, but are always beromin;.;, 
they have no fixed attributes. When we say that a thing is, we 
must In the same breath pronounce that it is not. There are 
always two of these fluxes, one the movement or change producing 
sensations, flux outside, the other the movement which receives 
the sensations, the flux of our senses. The result of the contact 
between them is that, for example, wood becomes white wood and 
the eye becomes a seeing 1 eye. When the flux of Socrates well 
comes in contact with wine, the wine will be sweet, but, if he is 
ill, it will be soun Both these statements will be true: in fact, 
all statements are true. What wine is depends entirely on the 
man perceiving it. There is no criterion of truth in external 
things, they change so rapidly. On the other hand, Gorgms of 
Leontini in his essay on Nature or the Non-existent hanlly 
caricatured the position of the younger Kleatics when he put 
forward the thesis that, if anything existed, it could not be known, 
and, if anything did exist and was known, it could not be com- 
municated. Such views as these or that of Kuthydenuis that 
falsehood is impossible are by no means universal among the 
Sophists, many of whom had no psychological or epistinnologiYal 
theories at all; and, where their views were sceptical, it was the 
scepticism not of one school, but of many* Aristotle justifies the 
revolt of the Sophists against philosophy, he holds that most of 
the leading Pre-Socratic systems tend implicitly or explicitly to 
the doctrine of Protagoras. Protagoras first called attention to 
the importance of the knowing mind in every act of kno\vlxlj;r. 
In the view of a plain man like Socrates all the systems were 
discredited and the question, what is knowledge, was for the time 
more urgent than the ambitious problems proposed by those 
who had sought to know the nature of the universe. Psycholo^y 
can glean nothing from the ethical discussions of the historical 
Socrates- When he declared that virtue is knowledge, he was 
confessedly using the latter term as one which neither he nor his 
interlocutors could adequately define. 

Plato in his writings is always talking about the soul, but not

particular for his imaginative sympathy with the whole mass of 
floating legend, myth and dogma, of a partly religious, partly 
ethical character, which, as was stated above, found a wide but 
not universal acceptance at an early time in the Orphic and 
Pythagorean associations and brotherhoods 1 . The Platonic myths 
afford ample evidence that Plato was perfectly familiar with all 
the leading features of this strange creed. The divine origin of 
the soul, its fall from bliss and from the society of the gods, its 
long pilgrimage of penance through hundreds of generations, its 
task of purification from earthly pollution, its reincarnations in 
successive bodies, its upward or downward progress, and the law 
of retribution for all offences, these and kindred subjects the fancy 
of Plato has embellished with all the beauty and sublimity which 
the art of a lost poet could bestow upon prose. Such themes stir 
his imagination. His approval of ethical fiction is attested by his 
own words, but it would be the height of imprudence to infer that 
any part of his philosophy is bound up with his gorgeous poetical 
imagery, Plato never set about writing a treatise De Artima. We 
find anticipations of a science, but not the science itself. In each 
dialogue he has a particular end in view. He proposes to examine 
the doctrine of Protagoras or, it may be, the import of predication. 
Incidentally in the course of a long controversy we corne across 
models of psychological analysis which for subtlety and insight 
have never been equalled. Such an analysis was something ab- 
solutely new. The psychical or mental states on which Plato 
fixed his attention had hitherto, when they were not ignored 
altogether, been confounded with their bodily concomitants: a 
mistake not unnatural, so long as both sensation and thought 
were regard cil as changes in the body. In the Tkcaetctus* we 
find the following argument. We do not perceive by but through 
the senses. What we perceive through one sense we cannot 
perceive through another. Consequently, if we know something 
about both a sound and a colour, it cannot be known through 
sense. Now we do know many such things ; that they are, that 
they are different from one another, that both are two things and 
that each is one. How do we know such facts? The soul appre- 
hends them through itself without any sense-organs. Being and 
Not-Being, likeness and unlikeness, number, identity and diversity 
are not apprehended through sense, but through the soul alone. 
The soul apprehends the noble and the base, the good and the

bad, not through the senses, but by calculating in herself the past 
or present in relation to the future. All men and animals from 
the moment of birth have by nature sensations which pass through 
the body and reach the soul, but to compare these sensations in 
relation to Being 1 and expediency comes with difficulty and re- 
quires a long time, much trouble and education. It is impossible 
to attain truth and know it without attaining Being ; knowledge 
does not consist in affections of sense because we cannot by them 
attain Being. It is by reasoning about sensations that this is 
alone possible. 

In the Phaedo^ the Platonic Socrates undertakes to prove that 
learning is reminiscence, which indeed is implied by the fact that, 
if questions are properly put, the right answers are elicited, showing 
that the knowledge sought, the knowledge, e.g. of geometry, existed 
previously in the mind of the respondent This proof is as follows. 
The picture of a lyre reminds us of the person who used the lytv, 
a picture of Simmias may remind us of Kebes or of Shntuius 
himself, so that the reminiscence may be brought about either in- 
directly or directly. If it is effected directly and the object seen 
is similar to the object it recalls, we cannot fail to see how tar 
the remembrance is exact For instance, we affirm thut there is 
an idea of equality which is called to our minds by our purcoptinn 
of sensibles which arc equal That this idea is something distinct 
from the equal sensibles is clear; for the sensible* may appear 
equal to one observer, unequal to another; but about the idea of 
equality no difference of opinion is possible. Now we are to 
observe that all sensible equals appear to us as falling short of 
the standard of absolute equality, which plainly shows that our 
knowledge of absolute equality is prior to our perception of the 
sensiblcs. And whereas (i) this sense of deficiency in the .sensible* 
has been present so long as we have had any perceptions of them, 
(2) our perceptions of them date from the moment of our birth, 
it inevitably follows that our knowledge of the idea must have 
been acquired before our birth. Now this of course applies to all 
ideas as well as to that of equality. Since, then, we have obtained 
this knowledge, two alternatives are open: either we are born in 
full possession of it and retain it through life, or we lose it ut 
birth and gradually regain it. The first must be dismissed on 
this ground: if a man knows a thing, he can give an account of 
it, but we see that men cannot give an account of the ideas ; it

follows then that the second alternative is true ; we lose this know- 
ledge and all learning is but the recovery of it. And since our 
souls certainly did not acquire it during their human life, they must 
have gained it before our birth and at birth lost it. Many more 
passages might be cited to prove that Plato kept the mental 
process distinct from the bodily process and that it is the former 
which he sought to explain. 

Though the various mental operations are often discussed and 
. e . distinguished, yet we find no exhaustive classification

opera ions. ^.^ . g ^^ ^ ^^ ^ ct #&& each attempt at partial 

classification is made, as above stated, for a special purpose, to 
prove a particular conclusion in a particular dialogue. Thus in the 
Republic 1 the tripartite division into reason, passion and appetite 
is brought in to show the relation of justice to the other virtues, 
and this, again, whether subordinate to, or coordinate with, the 
analogy between the individual and the state, is a means to the 
determination of a perfect political constitution, which is said in 
the Timaetts* to have been the chief subject of the dialogue. Nor 
does this tripartite division itself tally either with that into know- 
ledge, opinion (or sense-presentation) and ignorance 3 , or again, 
with the fourfold division into thinking, understanding, belief and 
conjecture (an expansion probably of the distinction between know- 
ledge and opinion), which we find in other parts of the Repiiblic*. 
In the Sophist* discursive thought is a dialogue of the soul with 
herself, opinion is the silent assertion of the soul in which this 
results, imagining is a combination of opinion and sensation. In 
the Philebus* Plato goes more into detail and distinguishes sen- 
sation, memory, imagination and recollection. When the affections 
of the body do not reach the soul, the state of the soul is said 
to be insensibility or unconsciousness. When the affections of 
the body are communicated through the body to the soul, there 
is sensation. The retention of such a sensation is memory, its 
non-retention, the fading of memory, is forgetfulness. The recovery 
of lost memories by the soul without the aid of the body is 
recollection. Later in the dialogue 7 the relation of memory to 
imagination is illustrated : the former is a scribe or recorder, what 
It records being propositions, opinions; the latter is a painter,

whose glowing pictures excite hope. In this dialogue also there 
is a practical end, all these distinctions being subservient to 
the classification of pleasures as true or false. Similarly in a 
memorable passage of the Ttoactetus* the introduction of two 
illustrations, one from a waxen block and the other from a dovecot 
or aviary, is incidental to a refutation of the thesis that knou'Icd^c- 
is true opinion. But the similes in themselves are contributions 
to psychology of permanent value. That of the waxen block 
presents in its sum and substance the entire theory of sensation 
conceived as an impression from without, like the print of a seal 
upon wax, and the theory of memory as the retention of such 
impressions, the different degrees of retentiveness in individuals 
being ascribed to the size of the block, the quality of the wax: 
and the number of impressions crowded together in small compass". 
The other, that of the aviary, conveys in a striking manner the 
relation between memory and reminiscence, the latter bcing the 
deliberate recovery of lost impressions ; at the same time it shows 
the relation between the mere possession of knowledge and its 
actual application or exercise. 

The most comprehensive view of Plato's psychology is to be 
found in the Timaeits. lie starts with reason or with

the operations of intellect. The soul thinks. This 
process is first described as it goes on in the soul of the universe 
or universal soul and, because it is an activity, is *, omened with 
circular motion. The revolution of two circles, that of the Same 
and that of the Other, gives judgments of identity and difference, 
the two most important relations, and without such jud^im-nt^ 
there can be no knowledge. But this ceaseless activity of thought 
from time to time suffers disturbance, and the interference results 
in sensation. In the allegory the creation of particular souls follows 
upon the creation of universal soul, and it is to those particular 
souls, each united to a body, that the following desnipfinn applies.

in a body, a body, as Plato says, "in-flowing and out-flmvm;;

neither controlled it nor were controlled, but bore and were borne 
violently to and fro. For great as was the tide sweeping over 
them and flowing off which brought them sustenance, a yet greater 
tumult was caused by the effects of the bodies that struck against 
them ; as when the body of any one came in contact with some 
alien fire that met it from without, or with solid earth, or with 
liquid glidings of water, or if he were caught in a tempest of winds 
borne on the air." The body of the animal, be it remembered, is 
composed of the same four elements, air, earth, fire, water, with 
which the animal comes in contact in alien bodies, whether in the 
process of nutrition or in that of sensation. " And so the motions 
from all these elements rushing through the body penetrated to 
the soul. This is in fact the reason why these have all alike been 
called and still are called sensations 1 . Then too did they produce 
the most wide and vehement agitation for the time being, joining 
with the perpetually streaming current in stirring and violently 
shaking the revolutions of the soul, so that they altogether hindered 
the circle of the Same by flowing contrary to it, and they stopped 
it from governing and from going ; while the circle of the Other 
they displaced ____ So that the circles can barely hold to one an- 
other, and though they are in motion, it is motion without law, 
sometimes reversed, now slanting, and now inverted ____ And when 
from external objects there meets them anything that belongs to 
the class of the Same or to that of the Other, then they declare 
its relative sameness or difference quite contrariwise to the truth, 
and show themselves false and irrational; and no circuit is governor 
or leader in them at that time. And whenever sensations from 
without rushing up and falling upon them drag along with them 
the whole vessel of the soul, then the circuits seem to govern 
though they really are governed. On account then of all these 
experiences the soul is at first bereft of reason, now as in the 
beginning, when she is confined in a mortal body 51 ." The soul, 
according to this account, is in ceaseless activity, and such normal 
activity, or thought, is from tixne to time disturbed by sensation, 
which has a tendency to pervert right thinking into falsehood 
and error. We might compare the definition from the Philebns 
above summarised 8 , in which it is said that when the bodily 
affections pass through both body and soul and give rise there 
to a sort of shock or tremor not only peculiar to each, but shared

by both in common, the movement which body and soul thus 
share may properly be called sensation. 

Plato started with intellect and thought. Rightly understood, 
he does not oppose body to soul, but rather sense to 

Sense and L A ' 

reason, reason, as one faculty of soul to another. But what 

are the limits of sense and reason ? To which should be referred 
the knowledge of relations of cause and effect, of good and evil ? 
Sense, we are told in the Republic^, is sufficient where a thing 1 does 
not tend to pass into or be confused with its opposite; where the: 
data tend to become confused, sense is insufficient and we must 
appeal to intellect. What sense perceives confusedly thought 
thinks distinctly and in isolation. Sense at the best can only 
give opinion, but reason and true opinion are distinct ** because 
they are different in origin and unlike in nature. The one is 
engendered in us by instruction, the other by persuasion ; the 
one is ever accompanied by right understanding* the other is 
without understanding; the one is not to be moved by pcrsua.su m t 
the other yields to persuasion ; true opinion we must admit is 
shared by all men, but reason by the gods alone and a very small 
portion of mankind 3 ." Sense and thought are concerned with 
different objects, the particular and the universal. The defects 
of sense are not in the subject, but in the object, because the 
particulars of sense are in flux and have no fixed being. Prota- 
goras held that sensible things have their so-called qualities only 
by acting or being acted upon and, as activity and passivity art? 
always relative, no quality belongs to any thing per jte*. We cannot 
say that they are per sc anything in particular, or even thai they 
are at all. They only become: things are always becoming, not 
being. When an object comes in contact with our scnso-organ 
and interaction takes place, a sensation arises in the organ and 
simultaneously the object becomes possessed of a certain quality. 
But the sensation in the organ and the quality in the object are 
results which are produced only by the contact and last only aw 
long as it lasts- In this doctrine of Heraclitus and Protagoras 
Plato acquiesced, so far as it relates to sense and sensibles. The 
testftnony of Aristotle on this point is explicit 3 and the dialogues 
confirm it But, instead of concluding with Protagoras that all 
presentations are relatively true and that there is no such thing 
as objective truth, he drew a different inference, viz. that, if there

INTRODUCTION. I xxxv 

is such a thing as knowledge, which he firmly believed, its object 
must be an intelligible object and an universal. 

The process of sensation in the separate bodily organs is 
Physiology of t ^ lus described in the Timaezis. " When that which 
the senses. j s naturally mobile is impressed by ever such a slight 
affection, it spreads abroad the motion, the particles one upon 
another producing the same effect, until, coming to that which 
is conscious, it announces the property of the agent : but a sub- 
stance that is immobile is too stable to spread the motion round 
about, and thus merely receives the affection, but does not stir 
any neighbouring part ; so that, as the particles do not pass on 
one to another the original impulse which affected them, they 
keep it untransmitted to the entire creature and thus leave the 
recipient of the affection without sensation. This takes place with 
our bones and hair and all the parts we have which are formed 
mostly of earth : while the former conditions apply in the highest 
degree to sight and hearing, because they contain the greatest 
proportion of fire and air 1 ." For the process of vision Plato 
adopts with modifications the theory of Empedocles, for the 
process of hearing that of the Pythagoreans. As to smell, he 
holds that odours cannot be classified according to kinds. For 
no element in its normal state can be perceived by smell, because 
the vessels of the nostrils are too narrow to admit water or earth 
and too wide to be excited by air or fire. They can thus only 
perceive an element in process of dissolution, when it is being 
liquefied or decomposed or dissolved or evaporated. The object 
of smell, then, is either vapour, which is water changing to air, 
or mist, which is air changing to water. The only classification 
we can make is that scents which disturb the substance of the 
nostrils are unpleasant, while those which restore the natural 
state are pleasant. In his account of tasting Plato makes the 
sensation depend upon the contraction or dilatation of the pores 
of the tongue by substances that are dissolved in the mouth, the 
peculiar effect of the principal flavours being briefly indicated. 
He made the flesh the organ of touch and, considering the various 
tactile sensations as relative to the tangibles, proceeds to explain 
what constitutes bodies hot and cold, hard and soft, heavy and 
light 3 .

xxxvi INTRODUCTION. I 

I have dwelt at what some may think inordinate length 
Plato, because in psychology, as elsewhere, making allowance for 
the fundamental difference between the two philosophers, we find 
nothing in Aristotle but the development in a systematic form of 
the Platonic heritage. It was the disciple's task to maintain on 
independent grounds the essentials of the master's doctrine on the 
subject of the soul, and to do this in face of the widely conflicting 
views and the general uncertainty which, as the foregoing sketch 
sufficiently shows, were prevalent at the time. With the conscious 
or half-conscious materialism of his predecessors Aristotle has no 
more sympathy than Plato and, as compared with this point of 
agreement, the differences between them count for little, howrver 
much Aristotle may exaggerate them. In the criticism which he 
passes upon the Timcteus 1 he affects to take the narrative literally. 
The point at issue is whether the activity which both Plato and 
Aristotle ascribe to the thinking soul can justly and reasonably be 
called a movement The doctrine of the two philosophers is on all 
important points the same: they agree that there is an immortal 
soul and a mortal soul, that the immortal element thinks always 
and that thinking must belong to its essence. What Plato calls 
41 movement" is familiar enough in Aristotle as "energy"' or 
41 activity-." If Plato would only say '* energy/ 1 there would 
seemingly be no room for objection. But in the tenth book of 
the Laws, the work of his old age, when he may have IHHMJ pre- 
sumed to have had some acquaintance with the views of his ciisdplt*, 
Plato obdurately refused to say "energy," and by his classification 
of the ten species of motion assimilated physical movement am! 
change to the only activity which in his view had malily, the,: 
"movement" of thought 3 , defining the soul as that which is ubU* to 
move itself. And after his death Xenocrates persisted in attribut- 
ing "movement" to the number which is the soul. At this point 
a brief summary of the first part of Aristotle's treatise m;iy htr 
Aristotle's the best means of indicating the way in which the 
treatise. writer approaches his subject and the conclusion* 

at which he arrives. 

At the outset, he says, we wish to ascertain the nutim: or

animal life. A few preliminary enquiries are suggested. Is soul 
" something " ? Substance ? Or quality ? Or to which category 
does it belong? Is it potentially existent or is it an actuality? Is 
it divisible or without parts ? This suggests the further question, 
Is it homogeneous in all species of animals ? If not, are the 
differences between souls generic or specific differences ? If it is 
without parts, it must be variable, there will be many sorts of soul. 
If it is homogeneous, the homogeneous soul must be made up of 
different parts. Ought we, then, to start with the whole soul or 
with the parts, ought we to study the parts first or their functions, 
and, if the functions, why not first the objects? As an apology 
for not deciding, it may be remarked that, while in order to 
know the properties of a thing, we ought to know its essence, yet 
knowledge of properties contributes to knowledge of essence : in 
fact, the one is involved in the other. 

The attributes of the soul cannot properly be separated from 
those of the body. The one that seems most separable is thinking : 
but, if this is akin to imagining or if it involves an image, neither is 
thinking separable. If any attribute is peculiar to the soul itself, 
then soul may be independent of body; if not, soul cannot be 
so independent. The attributes of soul are notions or forms in 
matter and, as such, fall within the province of the physicist or 
natural philosopher, while the dialectician studies and defines their 
form apart from their matter. Here is the point of difference 
between the objects of physics and of mathematics : the attributes of 
soul as such, e.g. fear and anger, are inseparable from the physical 
matter of the animals to which they belong ; the mathematical 
objects, e.g. line and surface, though really inseparable, are 
separable in thought from the concrete things to which they 
belong. 

From this discussion of method we pass to consider the 
opinions of our predecessors. The characteristics of animate being 
are motion and sensation. Hence some have regarded the soul as 
J>ar excellence the cause of motion, Democritus, who thought it fire, 
and Anaxagoras, being typical instances. All assumed that if a 
thing causes motion, it is itself moved. Others, again, start with 
the assumption that like is known by like and infer that the soul is 
-composed of all the elements, whether they are one or many: 
Empedocles that 'it is composed of earth, air, fire and water ; Plato 
of number. All definitions maybe reduced to three : that it causes 
motion, Is perceptive, is incorporeal The last characteristic leads 
those to choose the finest matter, who acknowledge none but

xxxviii INTRODUCTION. I 

corporeal elements. Subsequently it is objected that if the soul is 
a fine matter, as the soul is in all the sensitive body, we have two 
bodies in one. 

The application of the idea of motion to the soul leads, it 
is argued, to absurdities. There are four kinds of motion, loco- 
motion, qualitative change, decay, growth, and our enquiry is 
whether the soul is moved in and through itself, and not as sailors 
in a ship. All kinds of motion are in space ; therefore, if the soul is 
moved, the soul must be in space. As it moves the body, it would 
naturally move like the body ; and in that case it would o up and 
down in, and in and out of, the body. In general, we contend, 
the soul does not move the body, as Democritus supposed, by 
physical agency, but by means of purpose of some sort, that is, 
thought. The most thorough application of motion to explain 
soul, and in particular the soul which thinks, was made by Plato 
in the Timacus, and this is criticised at some length. Like other 
theories, it neglects the relation between soul and body in virtue of 
which the soul acts, the body is acted upon, the soul moves awl 
the body is moved. 

Another definition of the soul makes it a harmony or blending 
of opposites. This notion may be applicable to health or any 
bodily excellence, but will not apply to the soul. Harmony will 
not cause motion. Harmony means either (i) a close fit or adjust- 
ment of bodies, or (2) the proportion in which elements are mixed. 
It is needless to show that the first meaning is inapplicable, the*rc 
are so many fittings of the limbs. As to (2) t in flesh and blood 
the elements are mixed in different proportions; which mixturt* is 
the soul ? Returning to motion, we conclude that the only motion 
of which soul admits is motion per accident due to motion of the 
body, as whiteness is moved when a white body is moved* A 
stronger argument than any our predecessors have adduced is 
derived from the attributes of the soul, such as pain and pIwiMiiv, 
fear, anger, and other emotions, sensation and thought, all of which 
are commonly believed to be movements. In them, however, the 
soul is not moved: it is merely the cause of movement in the heart 
or some other bodily part It would be better to ascribe the.sc 
attributes to the man and say that he perceives or thinks or feels 
pleasure and pain with his soul. This leads to an interesting 
digression on intellect, followed by a refutation of Xcnucratcs, who 
< defined the soul as a self-moving number. How can the attributes 
which are known to belong to soul possibly be deduced from such 
a definition? It will not afford even the slightest hint of them. 



INTRODUCTION. I xxxix 

The same argument had previously been used against the definition 
of soul as a harmony. 

Two characteristics of soul, (i) that it moves itself, (2) that it is 
composed of very fine matter, have now been dismissed. Against 
the third, that it is composed of the elements and that like knows 
like, it may be urged that then the soul ought to have in it 
all compounds, all categories. Moreover, a unifying principle 
would be needed 1 . The soul is not to be held divisible into parts 
independent of each other, for in that case what keeps its parts 
together ? That must be the real soul. Again, as the whole soul 
keeps the whole body together, each part of the soul should keep a 
part of the body together : but we can assign no such function 
to intellect. 

Book II. begins by defining the soul. We premise that of 
entities to which categories are applied substance is one, where by 
substance we mean either (i) matter, which is not yet anything in 
particular, or (2) form, which makes it something in particular, or 
(3) the union of matter and form in the particular thing. Under 
substance in the last sense is included a natural body partaking of 
life. What we mean by life is the power of the body to nourish 
itself and to grow and decay of itself. Body is clearly matter here, 
therefore soul is form. And, if for matter and form we substitute 
potentiality and actuality and distinguish the first stage of actuality, 
corresponding to knowledge, from the second, corresponding to the 
exercise of knowledge, the soul will be the first actuality of a 
natural body furnished with organs, or of a body that has in itself 
the principle of movement and rest. Thus soul is the quiddity or 
formal essence, to which we have analogies in the cutting power of 
the axe and the visual power of the eye, both actualities in the first 
degree, as contrasted with actual cutting and actual seeing, which 
are actualities in the second degree. 

The definition thus found is the most comprehensive possible, 
applying to life in all its various forms, (i) intellect, (2) sense, 
(3) locomotion, (4) motion of nutrition, growth and decay. Plants 
exhibit life in its last form only. Animals, in addition to this, 
have sensation. Of the different senses touch is indispensable. 
Experiment shows that most of these vital functions are really 
inseparable from one another, though at the same time separable in 
thought Whether this holds of intellect also it is not so easy to 

1 Aristotle's own view is that the sense-organs are composed of the elements, in 
touch all are blended. But sense is not this corporeal organ itself, but rather the 
character or power which resides in the organ.

decide. If to these vital functions be added appetence, which 
clearly is present where sensation is, a certain gradation can be 
recognised. They may be arranged in an ascending series. The 
lower can exist without the higher, but the higher in mortal 
creatures always involve the lower. And there is a similar 
gradation in the senses. It seems, then, that there is one definition 
of soul exactly as there is one definition of rectilinear figure. Alike 
in figures and in the various types of soul, the earlier members of 
the series exist implicitly and potentially in the later ; the triangle 
is implicit in the quadrilateral and the nutritive faculty in the 
sensitive. The definition docs not dispense us from investigating 
in detail what is the soul in the plant, in the brute, ami in man. 

Having reached this point, we naturally expect that each of the 
four main vital functions, nutrition, sensation, intellect, locomotion, 
will be investigated in detail ; and this in fact is what the writer 
proceeds to do. Nutrition, growth and decay and reproduction* 
are dealt with briefly in Book II,, c, 4; sense-perception at very 
great length, Book II., c. 5 Book HL, c. 2; and imagination, which 
is intimately connected with sense, in Book in., c* 3 ; upon 
imagination follows intellect, Book nt, cc. 4 8 ; and, lastly, the 
principle of progressive motion in animals, which is identified with 
appetence, occupies us in Book in., ce. y 11. The treatise ends 
with an attempt, from the standpoint of teleology, to answer the 
question why the various forms of life occur in this ascending scale. 

Aristotle himself was not consciously con^tructinj; a new 
science. His discussion of the soul was forced uwn 

Method, , . . t , A1 . , , , , 

him when, traversing the wide domain he had set 
apart for his science of nature or physics, he passed from mor#ani<t 
to the borders of organic life. The method of science laid down 
in the Qrganon, and hitherto pursued, is a method partly inductive?, 
partly deductive, aiming to establish rational theories on rmpinVal 
data and often falling short of its aim, because either the data wtw 
at fault or the theories inappropriate, or because there were defects 
in both. Natural science has to do with nature ami with natural 
bodies, which by common consent arc pre-eminently Milvi;iitL;t?s, 
sensible substances. Nature is itself a cause of thin^N, tin* jnwcr 
in the things themselves which makes them whnt they are. Its 
characteristic is that, like human intelligence, it devises means to 
ends 1 . In this respect natural bodies or natural substances may 
be compared with the products of art and skill, but in the former

case the cause is, and in the latter case is not, in the product itself. 
We wish to know what are (i) the concrete natural substances, 
(2) their properties, (3) their physical changes, (4) the causes of 
these changes. If we could answer these questions, we should 
know the ends of nature in making concrete substances, the 
means used to realise these ends, the form and matter of which the 
substances consist. In logic we proceed from one determination to 
another. Psychology is concerned with mental acts or operations. 
In some of these operations we are conscious of a process ; for 
example, in operations of reason we know how we reason, by what 
steps we advance. To search for a method is to aim at determin- 
ing the order and arrangement in which these processes follow one 
another in any science. In geometry certain principles are assumed 
and necessary conclusions are deduced from them. Induction 
generalises from known particulars in order to obtain principles. 
Both induction and deduction may be combined in a more com- 
prehensive method which, after establishing general principles, 
deduces derivative laws and verifies the particular conclusions 
which follow from them. But it may be impossible to apply this 
complete method directly in its simplicity. The effects, which are 
conclusions, may be known, while the causes are to seek. If so, it 
is necessary to infer backwards and discover the causes from the 
effects. The early progress of mathematics and astronomy, with 
their applications to optics and harmonics, led to the belief, which 
Plato endorses, that deduction is the method of scientific research. 
Aristotle agreed for pure mathematics, while in applied mathe- 
matics he regarded induction from the materials collected as, 
strictly speaking, lying outside of the science and subsidiary. But 
in the natural sciences, where we rise from effects to causes, a 
thorough description of facts is a necessary preliminary to the 
discovery of the ultimate principles, and the inverse method must 
be applied. The method of astronomy, we are told, was to collect 
the facts, the phenomena, and from them to deduce astronomical 
laws. The whole method is summed up with convenient brevity 
thus : " In every department of nature we must first ascertain the 
facts and then after that state the causes." The task to which the 
History of Animals is devoted is thus described : " First let us 
ascertain the existing varieties of animals and the properties of 
each, and after that we must try to discover their causes. This is 
the natural method which puts the collection of material first 1 /'

Characteristic of Aristotle's mind is the notion that some things 
can be got at both deductively and inductively: it is the con- 
silience of fact and theory. The soul being a part of nature, 
psychology must needs be a branch of general physics, as all 
preceding thinkers, including Plato, agreed 1 . The presuppositions 
of Aristotle's metaphysics refer life to a cause. Vital phenomena, 
wherever found, are sufficiently alike in their manifestations to 
justify the assumption of one such cause. The treatise, then, is a 
preamble to all parts of the system dealing with plants, or animals, 
or with yet higher beings, if endowed with life. As one of the 
series of biological works, it stands in the closest connexion with 
the tracts known as the Parva Natnralia, with the morphological 
treatise De Partibits Animalhtm* and with that upon embryology, 
De Generations Animalinm. The part which the enquirer pr. .f-ssrs 
to take calls for very careful demarcation. It is impossible tn say 
what contributions, if any, Aristotle himself made in the field of 
psychology: the presumption is that they were but small. The 
evidence of his dependence upon Plato for all that relates to 
psychical phenomena is so overwhelming ', so constant, P"<sil>ty 
the repeated illustrations from zoophytes or stationary animals am! 
from worms, which give signs of life after they have been severed 
into parts 3 , are original; but in the main his facts are jm-rUfly the 
facts of his predecessors, the scantiest stock now at the disposal of 
any ignorant layman. Speculation had outrun observation. Nor 
is there any complaint of the scantiness of the data. No. Such 
as they are, they have already called forth too numerous and too 
divergent explanations. The writer's modest aim is by pivliminary 
discussion to settle a few, just a few, fundamental questions *H to 
the nature and attributes of the one principle of life and miiul, 

Aristotle's enquiry is founded on his motaphysirs. It is the 
Body and business of natural science to discover form and

plant is a natural substance, compomuU-d of body, which is 
matter, and soul, which is form, and the science of nature has 
therefore to investigate both body and soul Yet here a proviso 
is needed. Natural science does not necessarily treat of the whole

soul. Wherever soul as form is in matter, wherever it employs 
a bodily organ, we are still in the domain of natural science ; but 
anything included under soul which is independent of the body 
and which cannot be thus defined must be reserved for meta- 
physics 1 . The meaning which Aristotle attached to independence 
or separate existence must be grasped, if we would understand what 
he conceived by a substance or thing. Primarily this separate 
existence is the attribute of concrete particulars presented to 
sense in the external world. They are bodies locally, numerically 
and by magnitude separate. From them the conception is trans- 
ferred to whatever the mind thinks as distinct, and even for 
immaterial notions Aristotle has no other formula. They, too, 
like concrete bodies, are described as being in time, in space and 
in conception separate or distinct 2 . In reducing soul to the logical 
essence or form of body Aristotle, according to his own presup- 
positions, so far from favouring materialism, secures once and for 
all the soul's absolute immateriality. The living body has in- 
dependent existence, has its own form and its own matter. Even 
a dead body or an inanimate thing is something existing inde- 
pendently, to which we can apply the pronoun " this 8 . 1 ' But the 
soul does not exist in the same way. Nor, again, is it a thing 
capable of being added to or subtracted from another thing, the 
body, any more than form in general is a thing which can in 
mechanical fashion be united to and separated from its appropriate 
matter*. If a brazen sphere be melted down, the brass remains. 
It is still "this" something, "this" mass of metal; but we cannot 
then say of its spherical shape that it is " this " anything or that 
it any longer exists. The lifeless body is like the eye which 
cannot see or the axe which is spoilt for use 5 . We may apply to 
them the same names as before ; but, as the nature is no longer 
the same, the application is irrelevant, misleading, equivocal. But, 
though the lifeless body is still a concrete particular and a sub- 
stance, the soul apart from its relation to the body is no such 
thing at all. Now the soul as form stands to the body as matter 
of the concrete individual precisely as the spherical shape to the 
brass, as vision to the eye, as cutting power to the axe. In every 
case the form is a quality predicable of the matter. But the

body is not predicable of the soul, \ve cannot explain the soul 
In terms of body or make it a material thing, however fine the 
materials. On the contrary, we must explain body in terms of 
soul. It is form which determines and we only know a thing; as 
determined. Primary matter, the absolutely indeterminate, is in 
itself unknowable 1 . Therefore, if we would know the living body, 
we must study its activities and operations and all the attributes 
which it acquires in virtue of soul. Soul and body, then, arc not 
two distinct things, they are one thing presenting two distinct 
aspects. The soul is not body, but belongs to body 8 ; it is not 
itself a concrete particular, although its presence in the body 
makes a concrete particular ; it resides in a body and, what is 
more, in a body of a particular kind, furnished with the means 
whereby the functions of the soul can be exercised The relation 
of matter to form in the particular thing is one instance of a 
relation of higher generality, that between potenco and act** be- 
tween the power to become and the realisation of that power in 
actuality. Before it is, a thing may be or may not be, and when 
it is, if it has the power to act, it may act or it may not act- 
Now body stands to soul, and matter to form in general. *is the! 
potential to the actual which has reached the first sta^c and 
already is. In other words, the soul is the power which the living 
body possesses and the lifeless body lacks. This is first actual- 
isation or first entelechy. Again, the actual possession of faculties 
unused still stands to the exercise of these faculties in the relation 
of potcnce to act Life itself* the use of actual power, is the 
second stage, energy. The actual use must be prrccdrel by actual 
power. Soul is actual power to live y but is not life. In Plato 
body is opposed to soul. The body could be trainee! to obey the 
soul by gymnastic and music. In Aristotle the body is the natural 
instrument of the soul, and so the body into which a parttYubr 
soul enters must be adapted to its use. This fact renders the 
Pythagorean idea of transmigration absurd 4 . Soul is likewise 
both the final and efficient cause of the body*. It t's the final 
cause, because the soul is merely means to vital power and life; 
it Is the efficient cause not only in the obvious case of j;mj.;ri^>ivi- 
motion, but also in all the various changes which the body under- 
goes In the exercise of vital functions, including nutrition, growth, 
sensation.

Such, in brief, is the description of soul considered in and by 
classification ^self, including the various separate powers, which 
of vital are assumed to account for the varieties of vital and 

powers. , . , . 

psychical operations. The great problem is how this 
multiplicity of acts or operations should be classified. Plato in 
some dialogues divides soul into parts, an immortal part, reason, 
and two mortal parts, passion and appetite. His pupil is more 
cautious. He does not go beyond the supposition of certain 
powers or faculties. In one sense, he says, this division into 
powers is illusory, for the powers of soul are really infinite in 
number 1 . But he contends that his own groups are convenient 
groups. Faculties, like every other basis of classification, are 
only means to an end. Plato, he thinks, should have added the 
nutritive and sensitive faculties. Desire, again, runs through all 
operations : there is the rational wish, the angry impulse and the 
instinctive appetite. Here at least it is clear that the different 
powers are but different capacities of the single soul. Yet his 
ignorance of the bodily conditions of thought and his consequent 
assumption of a separable and immortal part of soul leave Aris- 
totle much in the same position as Plato. In order to get a clear 
view, special stress must be laid upon the statement that the 
powers of soul are arranged in an ascending scale 2 . In mortal 
creatures, at all events, the higher faculty always presupposes the 
lower, without which it cannot exist*. The lowest power, that of 
nutrition and propagation, is common to animals with plants; in 
plants it exists alone. Animals have sensitivity in addition : of 
the senses they must possess at least touch. So far we are on 
safe ground. From this point we may simplify in one of two 
ways. In the third Book the two faculties, sense and intellect, 
tend more and more to be conjoined as the judging faculty, while 
appetency, which in its lowest form is implied by sense*, is made 
the principle on which progressive motion depends". These con- 
siderations lead to the following scheme : 

r. Nutritive 2. Discriminative 3. Motive 

Sense Intellect Appetence Faculty of 

locomotion 

On the other hand, intellect is said to be the highest of all our 
powers, and the lower forms of appetency, as well as the power

of progressive motion, are associated with sense, while an inter- 
mediate place must be found for the imaginative facult}'. These 
considerations suggest the following table of faculties : 

I. Nutritive; 2. Sensitive, which is also appetitive; (this is in 
most animals joined with) 3. Locomotive; 4, Imaginative; 5. In- 
tellective. 

In the ascending series of vital functions we start with the 
The soui of lowest, which constitute the sole life of plants and 
the plant. are an indispensable element in the life of animals. 

Their isolation from all others in the vegetable kingdom facilitates 
their study. We accordingly assume 1 a power of self-nourishment, 
the nutritive faculty. But we must be careful to remember that 
this faculty has also to account for growth, decay and reproduc- 
tion ; by which last it partakes, so far as it can, of immortality, 
the species of plants, as well as of animals, being imperishable, 
though the individual members of the species perish. If we arc 
to define things by their end, the primary soul, the soul of the 
plant, is that which is capable of reproducing the species. But 
if the individual plant or animal is to be capable of this, it must 
be kept alive. Hence in a certain sense the subsidiary functions 
of nourishment and growth are even more important than the 
end to which they are means. Food or nutriment is the cor- 
relative object of the nutritive faculty, and we must determine how, 
things are nourished. It was a common opinion that contraries 
are nourished by contraries. This is generally, but not always, 
true of the elements or simple bodies. Fire, Aristotle points out, 
is nourished by water, but not water by fire. Others said like was 
nourished by like. These two views can be reconciled, I "indi- 
gested food is unlike, but food, when digested, has been assimilated 
to that which it nourishes, and then like is nourished by like* 
Nutrition, then, is motion or change, and it is easy to discm*cr the 
movent, the instrument and the moved* Soul is the nouri.shrr, 
food the instrument of nutrition, body the nourished. Vital heat, 
as well as food, is employed by the soul in the process, and we 
have an analogy in the steersman, who employs his hand to move 
the rudder with which he steers the ship. 

Little suspecting what advances botanical science was to make, 
Aristotle denied that plants have sensitivity- He admits that they 
are affected by heat and cold, but only, he argues, as inanimate 
things are affected ; that is, they are simply heated and cooled.

They cannot receive the form of objects without the matter, and 
this because they have no organ in which the elements are so 
blended as to give the means of discriminating, say, cold and 
heat. When a plant touches an object, there is merely physical 
contact. Thus the excessive preponderance, as Aristotle supposed, 
of " earth " in the structure of plants precludes sensation, because 
it precludes the proper blending of the elements, which would be 
necessary to make organs of sense. The insensibility of certain 
tissues of the body, e.g. bones, sinews, hair, he explained in a 
similar way as due to the pi-esence in them of too much earth : 
and in this erroneous view he followed Plato. 

The characteristic of animals when contrasted with plants is 
Sense . that they not only live, but have the power to per- 

perception. ccivo, which the Greeks regarded as essentially a 
cognitive power. They thought that we cannot perceive by sense 
without perceiving something, and interpreted this something 
objectively, as something which exists. The distinction so im- 
portant for modern psychology between sensation and perception 
had not yet received much attention. For Aristotle, as for his 
predecessors, the main question is, in what does this operation of 
perceiving consist and how does it take place? We must describe 
the various kinds of perception and determine how perceiving is 
related to thinking, since both are cognitive. One distinctive 
mark in that by sense we perceive individuals 1 . But we have 
much knowledge of individuals which the five senses cannot give. 
Does, then, all this knowledge come from sense, or must it be 
referred in part to intellect, or must we invent new faculties or 
powers to account for it? Suffice it to say that, whenever per- 
ception takes place, an universal is perceived, but not directly and 
fer se, only per accidens*. Directly sense perceives only "this," 
just as directly sense perceives it here and now. The operation 
of perceiving something existent is made by Aristotle to depend 
on his own physical theories of motion, of efficient cause and of 
essential form. One species of motion he defines as the production 
of an effect in matter by an efficient cause, as, e.g,, the production 
of an impression upon wax by a seal or of an image in a mirror 
by a candle. Motions may be classified according to the categories 
as qualitative, quantitative or spatial, and the species of motion to 
which sense-perception is referred is the first species or qualitative 
change, the alteration or transformation which a thing undergoes

when it loses certain qualities and acquires new ones, remaining 
itself numerically the same. The form or essence without the 
matter is transmitted by the efficient cause or agent to the patient 
upon whom it acts, as when fire transmits heat to fuel. The form 
or essence is one in all the things thus affected. The one universal 
heat is the same wherever actually found, in fuel ignited, in water 
heated or in molten iron. Applying this physical theory, we 
should define the particular motion or qualitative change which 
we call perceiving by sense as the production of an effect in a 
particular part of the body, which we call a sense-organ, by a 
particular external thing, which we call the sensible object. But 
this is inadequate. Plants receive heat and cold and the air 
receives odour, but they do not perceive 1 . It is not enough, then, 
to say that perceiving is undergoing some affection or being acted 
upon. Besides, what is affected ? Not the single organ, but the 
percipient as a whole ; and we have seen that the animal is a 
particular case of composite substance, the body being matter, 
the sentient soul form. Now it is with the soul that we perceive, 
as it is with the soul that we live and think 2 . Let us, then, amend 
the definition. Perception is an alteration in the soul. It consists 
in the production by an external object of an effect in the sensitive 
faculty. This effect is the reception of the form, without the 
matter, of the external thing perceived !) . 

Thus Aristotle is able to decide between the conflicting views 
of his predecessors, according to some of whom like acts upon like, 
while Heraclitus and Anaxagoras insisted that for any change to 
be perceived object and percipient must be unlike. As we saw 
about nutrition, both are right and both are wrong. The per- 
cipiendum is unlike, the perception is like, that which perceives it 4 , 
for, when the process of perceiving takes place, both the external 
thing which causes it and the percipient affected by that cause 
have in the very act one common form which, like every universal, 
is the same wherever it is found. That which sees is in the act 
of vision in a way coloured 5 , for it receives the same one form of 
colour which existed and exists in the coloured object perceived, 
But we may go a step further. Where one thing acts upon an- 
other, both the action and its effect reside in the patient, in that 
which is acted upon. Previous to their interaction, if they are 
physical bodies, the one is merely a potential agent, the other is

INTRODUCTION. I xlix 

merely a potential patient, whatever else they may be actually. 
Applying this to perception, the external thing is always per- 
ceptible, a percipiendum^ a potential perccptum^ the sense-faculty 
is always potentially percipient : but in the process of perceiving 
the potential in both cases has been transformed into an actual. 
The eye, e.g., becomes a seeing eye, the whiteness whiteness per- 
ceived, and these two actualities reside in that which is passively 
affected, in the sense. In other words, the actuality of the sensible 
object is one and the same with (not merely similar to) the actuality 
of the perceiving subject 1 , sense and sensible having in the act 
of perception one and the same essence, since the whiteness seen 
in the object is transferred to the visual faculty and, being an 
universal, a form, is one and the same, wherever it resides. Is 
this, we ask, a doctrine of relativity? Most certainly not. The 
followers of Protagoras are supposed to argue that, if the sensible 
quality is alone real, nothing would exist at all unless there were 
living beings to perceive, for without them there would be no 
perception. I grant, Aristotle replies, that in the absence of living 
beings there would be no act of perception, no affection of the 
percipient. But for all that, it would be impossible to get rid of 
things, which are potential causes of perception even when they 
are never perceived. For perception does not perceive itself, there 
is something beyond the perception ; and this must be logically 
prior to the perception, since whatever causes motion or change 
must be prior to that which it moves or changes : and this is not the 
less true because sensible object and percipient are relative to each 
other". In other words, the object perceived actually exists with 
its own form, its own qualities, even when it is out of all relation 
to a percipient And similarly we may conceive a percipient out 
of ail relation to an object, none such being actually present It 
is then what it always was, a power of perceiving, a faculty of 
sense, mere sensitivity. 

These considerations apply most emphatically and most natur- 
ally to sense regarded as a whole, a single power which resides in 
the body of the animal, likewise regarded as a whole* But this 
power of perceiving is localised and pluraliscd. Wherever a part 
of the body subserves a particular end or function, it becomes 
an organ or instrument, and the general power of perception, as 
specialised in the five senses, employs its separate sense-organs,

For the detailed account of the modes in which they are employed, 
the medium which they necessarily imply and their special objects 
or provinces, the reader must be referred to Book II. ca 7 n l . 
Here there is space only for a few general remarks. First, the 
parallelism between sense as a whole and the single special sense, 
e.g. sight or touch, must never be overlooked. u As the sensation 
of a part of the body is to that part, so is sensation as a whole 
to the whole sentient body as such 2 ." Thus the sense of vision 
presides over its own special province of colour, bounded by the 
opposites, white, black, and embracing every intermediate shade 8 . 
The sense of touching has its special province, or rather provinces, 
especially temperature and resistance, bounded the former by the 
extremes of hot and cold, the latter of hard and soft, and including 1 
all varieties of temperature and resistance intermediate between 
the extremes in each province. Vision resides in the eye, touch 
in the internal organ of touch (probably the heart) or in the 
intra-organic medium, the flesh, according 1 as we adopt the more 
scientific or the popular standpoint. To perceive is to undergo 
a qualitative change. In order, then, to become assimilated to 
the object, the organ must be capable of undergoing such change 
in the direction of either extreme or of any of the intermediate 
grades between these extremes. If it could not respond to the 
stimulus, as modern psychologists would say, at any point in the 
scale of colour, of temperature or of resistance* the failure on the 
part of the organ would be attended by mal-perception or non- 
perception on the part of the faculty. This is brought home to 
us whenever we try to employ our senses upon objects either 
altogether out of their range or such that the perception is at- 

1 As might be expected, the contributions to the physiology of the senses, and 
especially vision, are worthless. Sec Itaare* Creak Theories Introduction ; also

knowing nothing of cells, discusses sensation and movement without understanding the 
nature and functions of the nervous system, and treats fire as an element in blissful 
ignorance of the chemical changes which go on during combustion* If Aristotle had been 
in possession of a microscope, it is probable that he would have made no better ue of

tended by pernicious effects, when we try to see in the dark or 
to look at the noonday sun or to plunge the hand in boiling warer 
or to touch the air 1 . Now what is it which justifies our expectation 
that in normal cases a sensible object, when present, will be per- 
ceived ? What are the physical or physiological grounds on which, 
with the science of his day, Aristotle based this belief? He ac- 
cepted from Empedocles the false physics which resolved all 
bodies into four elements, air, earth, fire, water, with four primary 
qualities, hot, cold, wet, dry. These elements arc found in their 
compounds in the outside world. They are also found all four 
mixed (we might say, chemically combined) in the tissues or 
lumioLiiMU'inis parts of animal bodies, of which, again, the hetero- 
geneous parts or organs of animal bodies are composed. Hence 
there is a new application of the old maxim that like is known 
by like. The characteristic of each object perceived depends not 
so much upon the materials which enter into its composition as 
upon the combining ratio of those materials, which constitutes its 
form. When Kmpedocles resolved bone into definite proportions 
of his four elements, he was not far from realising that this com- 
bining ratio is the form which makes bone what it is 3 . So, too, 
with the sense-organ. It also has its combining ratio which con- 
stitutes its form, and this form, again, is the faculty residing in 
the organ. Hence sense as u whole, and each special sense, is a 
form, because it is the determining; proportion or combining ratio 
of the tissues composing the organ 8 . In perceiving, form receives 
and apprehends form. In order that it may j>erceive all the quali- 
ties which come within its range, the sense must be neutral or 
indifferent to all, must be a mean between the opposite extremes 
which it can perceive and be actually neither of them 4 . In the 
organ of sense the constituent elements are blended in a certain 
way, e.g, the finger has a certain temperature. But, as by the 
definition perceiving is qualitative change, this temperature must 
be capable of variation in the direction of cither extreme or of 
any grade intermediate to the extremes, and the constituent 
elements of the organ of sense must be blended in such a way 
as to allow of this. This possibility of variation serves to explain 
the discriminating power which attaches both to sense as a whole 
and to the single special senses. Whatever is intermediate be-

tween two extremes is differently related to the one and to the 
other. In Aristotelian language, any point in the middle of a line 
is the beginning of the line in relation to one extremity, the end 
of the line in relation to the other. The single sense sight dis- 
criminates two shades of colour. It is in a certain relation to the 
first when it perceives the first, it is in a different relation to the 
second when it perceives the second. The discrimination measures 
the difference between these two relations. 

The parallel between sense as a whole and the separate special 
senses extends to the objects directly perceived. The objects which 
the special senses directly perceive are known by two marks : they 
cannot be perceived by another special sense and the appropriate 
special sense cannot be mistaken about them 1 . The objects not 
exclusively belonging to this or that special sense, but perceived by 
two or more special senses, are referred to sense as a whole, often 
called scnsits coinmnnis* Such percepts are shape and magnitude, 
unity and number, motion, rest and time. They include what 
Democritus considered and Locke called the primary qualities of 
body. About this common function of sense as a whole there has 
been much needless mystification. The sentient soul is one, ant! 
all the more important and more intellectual of its functions belong 
to it in virtue of this unity. As one, it perceives the common 
sensibles ; as one, it pronounces judgments of identity and differ- 
ence between sensibles ; as a single faculty attendant upon each 
and every special sense, it is self-conscious*. That to sense as a 
whole, the so-called scnsits commnnis^ should be assigned functions 
which in degree, if not in kind 8 , exceed those of the separate special 
senses, need not surprise us* For in sense we have a whole which 
is something more than the sum of its different parts. Analysis 
into its elements does not completely explain it, nor will the simple 
addition of these elements reproduce what was subjVcti'<l to 
analysis* The operation of this single faculty is temporarily 
arrested in sleep, permanently in death. Lastly, to this faculty 
belong imagination, dreams and memory, which we are now to 
discuss.

objects within its own province (4*6 b to), and that it is by sight that we perceive that we

INTRODUCTION. I liii 

Sensation is defined as the production of an effect in the sense- 
images and organ, a part of the body, by an external object. It 
Sleep ' is, then, a movement or impression affecting the body 

and, so far as we are conscious of it, the sensitive soul as well. Now 
this movement does not always vanish with the disappearance of 
the object which caused it 1 . Instances may be given of its 
persistence, as our inability at first to see in a darkened room if we 
have just left the sunlight ; or what is known as the after-image 
(more correctly, the after-percept) when, if we close our eyes after 
looking at the sun, we see a succession of images of it in different 
colours 2 . It is by facts like these that Aristotle explains 
imagination. He defines it as a motion generated by actual per- 
ception, a motion distinct from, yet similar to, the motion which 
constituted the original sensation 3 , or, as Hobbes translates, " All 
fancies are motions within us, reliques of those made in the sense." 
In order to learn how wide is the range of the imaginative faculty 
we must turn to the tracts on Sleep and Memory. Sense itself is 
often mistaken in regard to the common sensibles and the things 
to which sensible qualities belong, for example, as to what the 
coloured or sonorous body is and where it is 4 : and these errors 
of sense arc shared in and increased by imagination, especially 
when the .sensible object is perceived from a distance. Illusion in 
general is due to the difference between imagination and judgment 
and between the standards they employ 15 . It may sometimes be 
corrected by one sense coming to the aid of another, as when the 
object perceived as double by crossed fingers is seen to be single . 
The illusion that objects seem to move past us, when we in fact are 
travelling past them, implies that a movement is set up in the eye 
of the same kind as would occur if we were stationary and the 
objects themselves were in motion. In fact, the bodily movement 
induces a picture of the very object which might have been its 
cause. It is to the imaginative faculty that dreams must be 
ascribed 7 . Sleep is the arrest of the sensitive faculty as a whole 
or seiisus communis^ by which when awake we are conscious that 
we are awake and have sensations 8 . Plants, having no sensation,

do not sleep\ In order that sense, which is charged with motive 
as well as perceptive functions, may recover from fatigue, sleep is 
necessary' 2 , and it is brought about ultimately by the process of 
nutrition 3 . An evaporation from the food in the stomach rises to 
the head 4 , is there cooled and descends, causing a feeling of 
drowsiness. The surface of the body is cooled and what heat there 
is in the system collects about the heart 1 "'. It is clear that dreaming 
is not a function proper to sense as a whole nor to any special 
sense, much less to understanding or opinion". Yet the images 
seen in dreams have sensible qualities. It only remains to refer 
dreaming to the same faculty as illusions in our waking hour*. 
The residual movements in the organs arc no doubt present in the 
daytime, but at night, when the action of the special senses is 
suspended 7 and the environment is peaceful, the imagination is 
most active 8 . Then #t* /lypot/iesi these persistent effects reach ant I 
stimulate the central organ of sense. We are most Habit* to 
illusions when labouring under emotion or morbid states'*, as, for 
example, when a patient in sickness mistakes figures on the wall 
for real an i trials' 10 and even makes bodily movements to escape from 
them. In sleep, again, the judging faculty is weak 11 , owing to tin: 
increasing pressure of blood around the heart 1 ' 4 . There are, of 
course, cases in which dreams are the result of semi-conscious 
sensations, half-heard sounds or half-seen lights |: \ which would have 
escaped attention in our waking hours: and reflections anil ideas 
arc often added to them 14 . But in itself dreaming is simply the 
result of the movement of our sensations during the period of sleep 
as such". Dreams are movements which give rise to images within 
our sense-organs 1 ". 

The most important of all our images are those: of memory, If 
Memory- imagining is consciously referred to an earlier JKT- 

image. ceptioti of which the image is a copy, then we. call tt 

memory 17 . For memory there are two conditions, tin; affection now

present, and the perception of time 1 ; in other words, not only 
images, but images regarded as decayed copies of earlier im- 
pressions, and this involves the perception of time. By memory 
we see distance, not indeed in space, but in time 2 . As memory is 
not confined to man, but extends to some of the lower animals, 
these latter must be credited with the imaginative faculty and the 
perception of time-'*. Here are very promising beginnings of a 
comparative psychology, which Aristotle, though he desiderated it 
in his predecessors, did very little himself to supply. His denial of 
understanding to brutes was a prejudice which a little research 
would have been able to surmount. As a matter of fact, he not 
only holds absolutely that, though the lower animals remember, 
they have no reasoning power, but, further, that, if memory were a 
function of pure intelligence alone, even man himself could not 
remember, since intellectual acts cannot be remembered per se*. 
What, then, can be remembered ? The instrument of memory is 
the image. Hence whatever can be presented as an image can be 
directly remembered, all that cannot be presented as an image can 
only be remembered indirectly by means of the images with which 
it is associated. But how can we know the past which is not 
present, if our only instrument is a present affection, the image 
which survives after the original impression is gone 5 ? Let us 
revert to the formation of images. The fact that a present move- 
ment of sensation sets up a subsidiary movement of imagination 
may be expressed in a different way, if we employ the metaphor of 
an impression, by which perception has been so often illustrated". 
The act of perceiving, as it were, stamps a particular impression 
upon the sense-organ, as a seal ring stamps an impression upon 
wax. This impression, which remains, is a potential image so long 
as it is latent, an actual image when we become conscious that it is 
still present. Is it, then, this image, the reproduced impression, and 
not that of which it is an image, which we remember? If so, it 
may be urged, remembrance is not of the past at all. At that rate 
we might just as well suppose that in actual sensation also we see 
and hear what is not present to sense ; an objection which cuts at 
the very root of every representative theory of perception. The 
objection is met by pointing out that in a certain way it is true that 
actual perception has for its object what is not present 7 . We see a

likeness of an absent person : the picture is present, the original is 
not The picture, though numerically one and the same, may be 
regarded in two ways, either as a simple picture or, in relation to 
the original, as a likeness. Apply this to the memory-image. It, 
too, may be regarded in itself simply as an image before the mind, 
or in relation to something else of which it is a representation. If 
viewed in the latter aspect, it is a memorial or reminder of an 
earlier perception which it recalls. It is distinguished from other 
Images by its reference to time past and by the fact that it is, what 
many images are not, a copy or representation. Memory may 
accordingly be defined not simply as a retention, but rather as a 
reference, of a mental presentation as a likeness to the original of 
which it is a likeness. All representations are likewise presentations. 
Images are before us in memory, in present sensation and in 
expectation, whether hope, fear, or desire, but we refer those 
images to the past, the present, and the future ivsptvlixoh" 1 . In all 
three cases something is presented, and the only way of clixtin^uUh- 
ing them is the accompanying perception of time, one of the 
common sensibles. Confusion of memory with imagination is one 
case of hallucination: thus Antipheron of Oreus was a lypc of 
mental derangement when he mistook what he only fanried 
for a past experience 2 . So far, then, like imagininj.; in j^omrrul, 
memory is a function of sensits communis^ and hence it is to the 
central organ of sense that we must refer this movement or 
impression or image, or whatever else we call the corporeal change 
in question. 

The distinction between memory and reminiscence or recollec- 
tion is never very clearly stated by Aristotle, but, if wo attoml to 
what he says about acquiring knowledge and ivac (jtiiiin^ it, i.e. 
about learning for the first time and learning over again what we 
have forgotten (neither of which, of course, is to be identified with 
memory or recollection), it seems that the case may be put as 
follows 8 . When we retain what we learn, whether by sense or 
thought, we are said to remember. Recollection implies the 
recovery of what has temporarily been obscured without going 
through the process of re-learning, and this whether the recovery 
is due to voluntary effort or is involuntary. We can remember 
without recollecting, if the image has never been lost, but Is Intent 
or potentially existent in us. When we recollect by voluntary 
effort we are conscious that it is lost and seek to recover it. Here

I cite at length the account given by Wallace, p. xcv : " Recollec- 
tion may take place either intentionally or unintentionally : we 
may, that is to say, recall some event of past experience either 
accidentally as it were or by the help of a distinct effort to call it 
back to mind ; but in either case it is regulated by certain laws 
which it is one of the great psychological merits of Aristotle to 
have tabulated for us. The laws which thus express the mode 
in which the mind attempts to recall its past impressions are what 
have commonly been designated since Aristotle's day, the Laws of 
the Association of Ideas. But to Aristotle, it must be added, the 
laws in question have little or none of the significance which they 
have acquired in the hands of modern inquirers. To him they are 
simply a statement of the manner in which we seek to regain some 
fragments of knowledge which have for the moment got outside 
our consciousness. Recollection in short being the recalling of our 
past impressions, it follows that the success of our efforts to recall 
them will depend to no inconsiderable extent on the degree to 
which we can recall the order in which other impressions stood to 
that of which we are in search. But our impressions follow one 
another in memory in an order similar to that in which the actual 
sensations succeeded one another. Recollection thus involves 
a study of the laws of sequence in the order of our ideas : and 
Aristotle analyses the method of recalling past impressions in the 
following manner. 'When engaged in recollection we seek to 
excite some of our previous movements, until we come to that 
which the movement or impression of which we are in search was 
wont to follow. And hence we seek to reach this preceding 
impression by starting in our thought from an object present to us 
or something else whether it be similar, contrary or contiguous to 
that of which we are in search ; recollection taking place in this 
manner because the movements are in one case identical, in another 
case coincident and in the last case partly overlap 1 .' Similarity, 
contrariety and contiguity are thus to Aristotle the three principles 
by which for purposes of recollection our ideas and impressions 
have to be guided. Our sensuous movements and impressions really 
follow one another in an order corresponding to that of external 
nature* Thus, the more order and arrangement there is in the 
elements of our experience the better connected our ideas are 
the more easily will they be remembered 8 . And again the greater 
number of times we have established a connection between our

ideas, the greater will be the ease with which we can recall them. 
Habit in short becomes a second nature : and the constant con- 
junction of two phenomena in outer experience will lead to their 
being so completely connected in the mind that the one will never 
show itself without the other 1 ." 

I have reserved to the last the highest employment of mental 
images in the service of the intellect. It is impossible to think 
without such an image before the mind-. When we arc contem- 
plating the object of thought, we must have an image before us. 
The past experience which we remember includes not only 
perceptions, but thoughts, and the reference of the image to 
sensus communis compels Aristotle to declare that nothing but 
what is sensible is remembered directly, per SL\ and that the whole 
of our thoughts, notions and conceptions are remembered indirectly, 
per accidents. Our thinking is conditioned by continuity, i.e. exten- 
sion, and by time. Just as in proving a geometrical proposition we 
are aware that the size of the figure does not affect the proof, but 
we nevertheless draw the figure of a determinate size, so in 
thinking, even though the object is not quantitative, we think of it 
as a quantum, and, if it is quantitative but indefinite, \ve neverthe- 
less think of it as of a definite size". What affections of sense are 
to the sensitive faculty, such images are to the thinking soul*. The 
total loss of a sense cuts off the man from all the knowledge 
available through that sense". Without the sensations in question 
he will not have the coin:-.pjiKling images, and without them he 
cannot have the thoughts and conceptions* Intellect itself duos 
not think external things without the aid of s^nsc- percept ion 11 . 
Further, the use of images in thinking implies their use in that 
process of deliberation in which the mind balances the present 
against the future, and after due calculation decides upon a course 
of action 7 . When reason is obscured by passion, images of sense 
themselves directly move to action, and such images control the 
movements of the lower animals generally".

INTRODUCTION. I lix 

previously made on thinking, on intellect, or even on the soul, 
where the context suggests that Aristotle, like Plato, is using soul 
for that which thinks. 

If to think is a species of imagining or not independent of 
imagining, even thinking could not exist apart from body. 
Anaxagoras made soul the moving cause when he said that 
intelligence set the universe in motion. But, whereas Democritus 
absolutely identified mind with soul and did not use the term mind 
to denote a faculty conversant with truth, Anaxagoras was less 
consistent. He often made mind the cause of goodness and order; 
elsewhere he identified it with soul, as when he attributed it to all 
animals, great and small, high and low. And yet, Aristotle adds, 
mind in the sense of intelligence is not so widely distributed as 
soul or vital principle. Anaxagoras took mind as his first principle 
and said it alone of all existing things is simple, unmixed, pure. 
He attributed to one and the same principle that it knows and 
that it causes motion. Mind, according to him, is impassive and 
has nothing in common with anything else 1 . 

The criticism 2 of the Timaetts suggests that in Aristotle's 
opinion the mind in the universe is not a magnitude ; it is one and 
continuous in the same sense as the process of thinking, which 
consists of a series of thoughts ; the unity of these thoughts is a 
unity of succession, the unity of number, not that of a magnitude. 
Hence, mind not being continuous like a magnitude, there are two 
alternatives : either it has no parts, or it has parts and is con- 
tinuous, but not like a magnitude. A magnitude is incapable of 
thinking ; if mind can apprehend with any one of its parts, it need 
not revolve nor have magnitude ; it has to think two kinds of 
objects, the one kind divisible, the other indivisible. Thinking, as 
we know it, has limits which determine it, viz. the end in view or 
the new truths that the thinker discovers. Both thinking and 
inference bear far more analogy to rest or pause than to motion. 
In thinking the thinker ought to realise happiness. Thinking is 
the essence of the mind. Many held that entanglement in the 
body was a hindrance to thought ; a satisfactory theory ought to 
explain why the thinking soul is enclosed in the body and 'under 
what conditions of the body. 

In criticising the doctrine of harmony, he asks, what part of the 
bodily compound combining with the rest, can we assume to be 
intellect 3 ? In another connexion Aristotle says that intellect

would seem to be a self-existing substance which comes into play in 
us and is in itself imperishable, in spite of senile decay. Thought 
and its exercise are enfeebled when something- internal is destroyed, 
but the intellect in itself is impassive. Memory, love and hate are 
not affections of the intellect, which is something more divine and 
is impassive 1 . In criticising Empedocles, Aristotle remarks that it 
is impossible for soul, and still more impossible for intellect, to have 
anything superior to it and overruling it, to it belongs a natural 
priority and authority 2 . It is difficult to conjecture what part of 
the body intellect holds together or how it can hold together any 
part 3 . After soul has been defined, we are told that there is as yet 
no evidence to show whether intellect is, like some of the other 
faculties of soul, really inseparable and only logically separable, 
from the rest It would seem to be a distinct species of soul and 
capable of separation, as the immortal from the perishable 4 . 
Sensation is of particulars, knowledge of universals, which are in a 
manner in the soul itself. Hence it is in our power to think 
whenever we please . To think is not the same thing as to have 
sensation, though they were identified by the ancients, who believed 
both to be corporeal changes' 5 . Nor is thinking the same as 
imagination or as belief 7 . Imagination leads to action in the lower 
animals because they have no intellect, and sometimes in man 
when intellect is obscured by passion, disease or sleep**. 

What conclusions can be drawn from these scattered remarks ? 
Apparently in one passage we have a choice of alternatives : either 
intellect is without parts (and therefore by the presuppositions of 
the Aristotelian system must be immaterial and an energy), or it is 
something continuous, which is, however, continuous only like a 
number or series, by sequence, and not by coherence, like a 
magnitude, A bodily organ, which has parts, would alone secure 
the continuity of coherence ; and for such an organ there is, or so 
Aristotle believed, no evidence. With this agrees the tentative 
assumption that intellect is something impassive, independent and 
imperishable, since its decay in the individual is an accident and 
not its real essence. 

The account of intellect in Book in., cc. 48, is condensed and 
imperfect and falls far short of the clearness which marks the 
exposition of sense-perception. Intellect is especially concerned 
with quiddities and universals. It employs no bodily organ, for of

the functions of the nervous system Aristotle and his contem- 
poraries had no idea. It contains a divine element, which is 
independent of the body and immortal. This summary tells us 
hardly any more than we have collected from the casual or 
polemical remarks in the previous part of the treatise. But 
Aristotle might fairly claim to have set before us his view both of 
(i) the difference between intellect and sense, and (2) the way in 
which thinking comes about : and this is all he promised at the 
outset 1 . 

(i) There is an analogy between sense and intellect, there is 
also a difference. Both furnish knowledge, both pass judgments, 
both are intermittent, sometimes in act, sometimes not. When in 
activity both have an object, the transition from the dormant 
power to its actual exercise does not depend upon sense alone or 
upon thought alone, and, when the activity is over, the alteration 
thus undergone leaves intellect absolutely, and sense to a great 
degree, unaffected. Sensitivity in the abstract is "a form which 
knows or apprehends sensible forms. Similarly intellect is a form 
which knows or apprehends intelligible forms 2 . Moreover, in both 
sensation and intellection alike at the moment of apprehension, 
there is identity between the form which apprehends and the form 
which is apprehended. Again, sense-perception is always true of 
its own appropriate object, and similarly thinking is always true in 
respect of quiddities 3 . On the other hand, the external object which 
stimulates the sense-faculty to activity is an individual, a particular, 
and it is external to the percipient; whereas the universals, the forms 
which we think, are present in the understanding, at any rate, of the 
mature man. Sensation cannot dispense with a bodily organ, a part 
of the body appropriated to its special 'functions. For intellect no 
such organ can be discovered. Yet, when a sense-organ is wanting, 
the action of intellect is impeded, for all knowledge through that 
sense is cut off 4 . Moreover, excess in the sensible fatigues or 
destroys the organ of sense, but the activity of thinking cannot 
be thus impaired. Again, intellect is the higher faculty of the two 
and implies the lower ; the lower does not imply the higher. For 
actual thinking the indispensable condition is the presence of a 
mental image, for, as we saw above, we think of nothing apart 
from continuity. Even when the object conceived is not itself 
a quantum, we nevertheless think of it as such. And we never 
think of objects without thinking them in time 5 .

(2) The process of thinking an object is explained in much the 
same way as the process of perceiving an object by sense. In spite 
of the differences stated above, both, as acts of apprehending, are 
assimilated to the process of reciprocal action between physical 
bodies. Apprehension is reception of form. If the mind knows 
objects by receiving them, since nothing receives what it already 
has, it must be assumed to be at first without them ; and further, so 
long as it remains capable of thinking, the same condition must be 
fulfilled for every fresh act. Hence intellect must be impassive, 
suffering in no way by the change from power to act and, since it 
thinks all things or, in other words, is capable of receiving all forms, 
it must in itself be devoid of any form, though at the same time it 
* 4 provides room for forms." It may be called* then, a mere 
aptitude or capacity to think. Until it actually thinks them, it is 
none of its objects, but becomes each object in turn when it thinks 
that object. In physical action there is a transference of essence 
or form : in combustion the form of heat is transferred from fire 
actually alight to combustible fuel. When a white object is 
perceived, the form of whiteness is transferred from the object to 
the eye and, as there is but one such form, is the same in the 
percipient sense as in the external object. And so when we think 
a stone, a horse, a triangle, the form or essence in our mind, the 
object of thought, is identically one with the form or essence outside 
in rentm natitra. As a contribution to the theory of knmvlr<l^;t% 
this explanation is adequate. External things affect our sense. 
By sense we apprehend hot and cold and whatever other sensible 
qualities are accidents of flesh 1 . We think each sensible quality, 
generalising and abMracting the univcrsals, of which sense by itself 
informs us only per accidcns. The substance in which the attributes 
inhere, which is said to be indirectly perceived by sense, is directly 
judged and known by thought. 

So far intellect has been treated as one. It is possible to apply 
to this unity the analysis which resolves particular things. When 
nature generates or art produces a concrete particular, three 
conditions arc fulfilled. There is the efficient agent transmitting 
form, there is the passive recipient upon which form is impressed, 
and there is, lastly, the result of the process, the new particular into 
which matter impressed by form has been made. To manufacture 
a brazen sphere, we need the craftsman with the design in his 
mind and brass to receive that design. The form of a sphere is 

1 459 b 14 1<5. 



INTRODUCTION. I Ixiii 

impressed upon the brass and a new particular is made, precisely 
as the form of humanity is transmitted from father to son 1 . Our 
knowledge and actual thinking answer to the manufactured 
product, they are generated in the receptive intellect by something 
which must be assumed in intellect itself to correspond to the 
efficient cause. That which on one view is the reception of essence, 
is on another the spontaneous transition from potence to act. This 
is true of sense. Sense becomes like its object, in quality identical 
therewith. But it is just as true to say that sense has risen from 
the lower stage of potence to the higher stage of act and realised 
itself in full activity. So, again, thinking is reception of the form 
or essence, but it is just as true to say that intellect has risen from 
the lower stage of potence to the higher stage of act and realised 
itself in full activity. Perception, it is true, cannot be explained 
without assuming interference from without. The occasion which 
supplies the stimulus to the transition must be something given. 
With thought it is different. The occasion, the stimulus, are not 
external, but internal. I may say, if I like, that my potential or 
passive intellect has been acted upon and educed into actuality : 
but what brought this about ? A mental agent, the active intellect, 
has called forth this activity and produced the thought. In my 
individual experience the power to think precedes actual thinking, 
but the transition cannot be explained except by assuming the 
prior existence of the efficient cause which brought it about. This 
point once reached and the unity of intellect being resolved into 
agent and patient, it follows that the agent which we postulate 
must have the same attributes as the patient, of which we have 
experience. It must be separable, impassive and unmixed, because 
its essence is activity, as the essence of the other factor is poten- 
tiality. Could it be actually separated and exist independently, it 
would be eternal. But this eternity is not communicated to the 
other factor of intellect, or to the intellect as a whole. Is such a 
hypothesis necessary ? Can the potential intellect be affected by 
external things ? So far as these things have matter in them, they 
are objects of thought only potentially. The intelligible forms are 
Implicit in the sensible forms, and intellect ex hypothesi has no 
special bodily organ. But so far as knowable things are pure 
forms, no such expedient is required. The question, then, why an 
active ' intellect is introduced, may be thus answered. It is in 
order to provide a cause of that transition from potence to act 
which takes place whenever we actually think.

Ixiv INTRODUCTION. I 

The difficulty in understanding what Aristotle did or did not 
Diverse inter- intend by this analysis of the intellect, or rather this 
pretations. distinction of the intellect which makes from the 

intellect which becomes, is notorious. The scanty comments of 
Thcophrastus 1 develop various lines of acute criticism, which in my 
judgment are not incompatible with an acceptance of the doctrine. 
So much is clear, that Theophrastus considered intellect in both its 
forms, as making and becoming, to be our human intellect, which is 
connatural and in us from birth to death, though its origin is 
elsewhere. In face of the difficulties which he is at pains to 
develop he seems content to regard the passive intellect dependent 
upon the body and the human intellect which results from the 
union of the passive with the active as in a sense distinct, yet as in 
another sense one nature, in so far as the two are related to one 
another as matter and form are in the unitary thing. That the 
active intellect exists per se in man independent of the passive is 
nowhere stated or implied either by Aristotle or Theophrastus, 
From a casual criticism by Themistius 3 it appears that certain of 
his predecessors had identified the active intellect with the 
premisses from which all our knowledge is derived and with the 
knowledge itself which we gradually acquire. Alexander of 
Aphrodisias", who endeavoured to preserve faithfully the teaching 
of Aristotle and to present it as consistent, distinguished a material 
intellect and an intellect /;/ habitii* which the former becomes by 
actual thinking and reception of the intelligible form. The material 
intellect is the mere aptitude for thinking: this is a power or 
faculty of the individual human soul, the form of the body. Lastly, 
there is the active intellect which is not a faculty or part of the 
human soul, though it is in it from birth to death whenever we 
actually think : not only when we think it or any of the immaterial 
forms with which it is identical, but also when we think forms in 
matter, for it is only through the agency of the active intellect that 
actual thinking is possible. Being wholly immaterial, energy 
devoid of all matter and potentiality, it always is, even when it in 
not thought by men ; it is an eternal, imperishable, self-existent 
substance* There can be but one such substance: it must const*. 
quently be identified with the deity, the first cause of motion in the 
universe, whose nature and essence is activity, the energy of

thinking. In individual men it supervenes as something coming 
in from outside. It finds in the capacity of thinking which does 
belong to the human soul an instrument ready for its use, upon 
which it can work and produce actual thinking. As to the reason 
why men think not always, Alexander has no better explanation to 
offer than a suggestion of his teacher 1 , that the craftsman is still a 
craftsman even when he has laid aside his tools. The eclectic 
Themistius 2 refused to identify the active intellect with the deity 
outside man. He appeals to two expressions of the master 
(l) "that these differences must be present in the soul," (2) "this 
alone is immortal and eternal," which he thinks Alexander's 
interpretation forces out of their natural meaning. As to (i) 
Alexander has his own explanation to offer, according to which the 
active intellect, and therefore the deity, is in our mind whenever we 
think : but there is some force in the contention that Aristotle 
would never have described the deity as "alone" immortal and 
eternal. However, the point in which Themistius agrees with 
Alexander is more important than the points in which they differ. 
He fully admits that the active intellect is one and the same in all 
men, it is distributed among different individuals as light is divided 
into single rays. Of the other commentators, the Neo-Platonist 
Simplicius 51 distorts Aristotle's account in order, as far as possible, 
to adapt it to his own philosophical presuppositions. According to 
him, the rational human soul is one immortal substance. It has 
three states: in the first it remains in itself; this is the active 
intellect. In the second it enters the body; it then knows nothing, 
but is the pure potentiality of thought. Intellect of the first stage 
acts upon intellect of the second stage, and the result is the third 
stage, when intellect is in habitu and acquires knowledge. The 
passive intellect is mortal, because it ceases to be passive and is 
absorbed in the higher or active intellect. It is not worth while to 
pursue the course of speculation further among Arabian philoso- 
phers and the schoolmen, in both of whom the theological bias is 
unmistakeable. Avicenna 4 was an original thinker who exerted a

great influence on his successors ; but neither his distinction of 
universals, ante res, in rebns, post res, nor his doctrine that these 
universals are at once substantial forms in things outside us and 
intelligible forms to the mind which thinks them by abstraction 
has any direct Aristotelian authority, and when he makes both 
forms alike emanate from the active intellect and ultimately from 
God, this doctrine becomes nearly akin to that of the Nco-Platonists. 
Averrocs and Aquinas, though both professing to interpret Aristotle, 
modify his doctrines to suit their own preconceptions. According 
to the former, neither passive intellect nor active intellect is part of 
the human soul as defined in the definition. In scholastic language 
each is forma assistens, snperveniens and not forma dans csse 
homini* Each is immortal and each is one and the same in all 
men. According to Aquinas, active intellect as well as passive 
intellect is a faculty of the rational human soul, which was created 
by the will of God and is yet immortal, having the power as form 
to provide a vehicle for itself after it is separated from its present 
body. Regarded as interpretations of Aristotle's doctrine, those 
two conflicting views, which divided the allegiance of the later 
schoolmen, cannot both be right, but may both be wrong. Aristutle 
himself was free from the preconceptions of his two commentators; 
he was not a Moslem mystic nor a Christian theologian. 

These successive attempts to fill in the meagre outline 
presented by the text of DC Anima proceed in two directions. 
Either they make the two intellects two faculties of the human 
soul, or they seek to identify one, if not both, of them, with an 
intelligence outside man, Alexander, Averroes, and in modern 
times, Ravaisson and Kenan, have gone to the greatest lengths in 
the latter direction. But, if the act of thinking is independent of, 
or alien to, man's nature, how can the aptitude for thinking be any 
longer a part of it ? Averroes no doubt is consistent : lie declares 
the passive intellect also to be an immaterial substance and no part 
of the soul which is the form of the human body* But, in order to 
maintain this, he is obliged to do violence to the language of the 
treatise. In particular, his virtus cogitatitw, with which, according 
to him, the definition of soul endows man, has to be divorced from 
intellect proper and reduced nearly to the level of sensus annmunis 
or imagination* Even then he is unable to explain why, after the 
definition of soul has been obtained, it should have been left an 
open question whether intellect properly so called is or i.s not a 
part of the soul 1 , or why it should be designated as a ** part " when 

1 413 b 13 26, 415 a 11 K<j, 



INTRODUCTION. I Ixvii 

at last it comes up for special treatment 1 . But in fact all views in 
which human intellect or a part of it is identified with the activity 
of divine intellect are met by the same insoluble difficulty : what is 
to be made of the intellect which becomes all things ? Modern 
enquirers are hopelessly divided as to what the passive intellect is. 
Trendelenburg answers " all the lower faculties in contradistinction 
to the active intellect 2 ," Zeller "the sum of those faculties of 
representation which go beyond imagination and sensible percep- 
tion and yet fall short of that higher Thought, which has found 
peace in perfect unity with its object 3 ," Ravaisson " the universal 
potentiality in the world of ideas 4 /' Brentano " Imagination 5 ," 
Hertling <l the cognitive faculty of th'e sensitive part 6 / 3 and 
Hammond, if I understand him rightly, "the life of sensation as a 
potentially rational mass/' " the sum of the deliverances of sense- 
perception and their re-wrought form in memory and phantasy, 
regarded as potentiality 7 ." The last two would seem almost to 
identify its functions with those of sensus communis as a judging 
faculty. Now these various answers do not accord with the 
description in De Anima of the process and act of thinking, 
whether as apprehension of the intelligible object or as the 
judgment which makes two concepts one ; they do not fit either 
the conception of intellect in habitu, the process by which 
knowledge is acquired, or the sharp distinction drawrT between 
a thought and a mental image. Thinking is not the same as 
receiving or retaining or remembering or judging the percepts of 
sense, which are all individual and lack the universality required. 
Abstraction alone renders thought possible, and abstraction cannot 
be restricted to the active intellect Again, all the operations of 
thought imply a single judging power. This position, which 
Aristotle has maintained for sense, he would certainly maintain as 
strongly for thought. When he controverts the Protagorean maxim 
and points out that it must lead to universal relativity, he contends 
that there is such a thing as absolute existence, a something 
determinate in itself apart from all relations, for presentation of an 
object implies a subject to whom the object is presented 8 . The

object of thought, then, implies a thinking subject If these 
modern interpreters were right in equating the intellect which 
becomes with one or other of the lower faculties or with the sum of 
them, then the functions of these faculties would be identical with 
the function of thought, so far as the intellect becomes all things. 
But the lower faculties, sense and imagination, never succeed in 
obtaining an object which is a true universal. 

If, however, we vindicate the right to think for the intellect 
which becomes all objects and is said to be in habit it when it 
acquires knowledge, it would seem that this can only be clone at 
the expense of the intellect which makes all objects. The functions 
of the latter are then reduced within the narrowest compass. 
According to some, it does not really think at all, it docs little more 
than "illuminate" the mental image, thus facilitating the abstrac- 
tion of the universal form. But Aristotle speaks of its perpetual 
activity, he says there is no intermission in its thought 1 . Vet it is 
not unreasonable to suppose that determinations so unlike us 
"pure potentiality" and "incessant activity 1 * refer to the same 
thing under two different aspects. Each describes it abstractly, 
and, to know the whole, the two determinations must be combined. 
If there is within us a thought which is continuous and always in 
activity, at any rate experience docs not tell us so% it can only bo 
a conclusion of reason* How, then, did Aristotle reconcile this con- 
clusion with the facts ? Apparently he made this thinking latent. 
The intellect always thinks, but we do not remember. This, then, 
is what the attribute " potential" means as applied to the intellect' 1 ; 
and this agrees with the conception of the powers or faculties of 
the soul in general, which are permanent possessions, all dormant 
and unconscious, until roused to activity in consciousness. Here 
we may recall a previous use of the antithesis between potential 
and actual in Aristotle's account of hnaginatinn. The images or 
survivals of sensation are not always present to con.sciousnc.ss, yet 
Aristotle treats them as still in existence; they continue, he says, 
in the organs of sense, they are potential images while they are 
dormant, actual images when they are revived and reappear, as we 
should say, in consciousness 4 . It may be worthwhile to hazard the 
conjecture that the intellect which does not consciously think is

similarly described as potential intellect, and yet all the time its 
thoughts are there, though its incessant activity is subconscious. 
It will be seen that, though I do not entirely agree with Wallace, I 
nevertheless recognise a certain element of truth in his solution of 
the difficulty. He thus conceives the relation of the two intellects : 
" the creative reason is the faculty which constantly interprets and 
as it were keeps up an intelligible world for experience to operate 
upon, while the receptive reason is the intellect Jipplyin^ itself in 
all the various processes which fill our minds with the materials of 
knowledge 1 ." And again: "the two it must be remembered are not 
'two reasons': they are merely different modes of viewing the 
work of reason V 

In the account of sense and thought, with which we have been 
r>esire and hitherto mainly occupied, the cognitive element is very 

volition. prominent. It is natural to infer that our philosopher 

regards man chiefly on the intellectual side, as a spectator of the 
universe, a being who contemplates. And this impression would 
seem to be confirmed when we learn from the Ethics wherein 
man's chief good consists. But no Greek could overlook the other 
side of human nature. The conclusions of the Ethics must be 
taken in conjunction with the wider generalisations of the Politics \ 
and, if the self or ego is identical with intellect, intellect is practical 
as well as theoretic. The true is in the same class with the good ; 
good, real or apparent, is the goal of all striving and effort. With 
his teleological bias, Aristotle would have endorsed the words of a 
modern psychologist 5 *: " Looking broadly at the progress of life, as 
it ascends through the animal kingdom and onwards through the 
history of man, it seems safe to say that knowledge is always a 
means to ends, is never an end by itself till at length it becomes 
interesting and satisfying in itself. Psychologically, then, the sole 
function of perception and intellection is to guide action and

8 p. cxv. Wallace was not alone in holding that Aristotle never intended to affirm 
two distinct intellects, but only to distinguish two phases or aspects of the one intellect. 
A similar view is maintained on very different grounds by Bullinger, Nits-Lehre* pp. 34$qq. f 
and by Mr F. Granger, Class. Aev. vi. pp. 298 301, who states it as follows : "the reason 
is passive and affected by corporeal conditions, so far as it uses the tpavrda-^ara, grasping 
the tfo? from among them. It is purely active only when it concerns itself with 
voyjrd, among which itself is included." Cf. Brandis, Gesch. der JSiitw. I. p. 518, 
J&andbuch* II. b, 1178. Kampe and Grote came to the conclusion that intellect, though 
separable from the human body, is not separable from body in general. They affirm that 
it has for its necessary substratum the ether, the most divine of the elements : Kampe,

subserve volition more generally, to promote self-conservation and 
betterment." In De Anima, a professedly biological treatise, with 
the soul in all living things for its subject, this part of the enquiry 
is not pushed far 1 . The main outlines are given, but \ve must look 
elsewhere, and particularly to the Ethics, for further details. The 
problem is presented in a very simple fashion. In the animal 
world motion, in the sense of locomotion > is an all-pervading fact, 
and but slight observation suffices to show that this motion is not 
random or irregular, but is directed to an end. To what power or 
faculty, then, is it to be ascribed? The nutritive faculty, Aristotle 
thinks, sufficiently accounts for movements of growth and decay, 
whether in animals or plants, but not for the progressive move- 
ments of animals, movements prompted by want and directed to 
an end. If the nutritive faculty were sufficient to produce such 
movements, Aristotle adds with unconscious irony, plants would 
move spontaneously and would have organs adapted for th: 
purpose. Nor can these movements be explained as due to the 
sensitive faculty, since there are whole genera of perfectly-developed 
animals of a low type which do not move from place to place. 
But if locomotion were implied in sensation, they, too, would have 
organs adapted for locomotion. Is intellect, then, the cause of 
which we are in search, as Plato thought ? No. Intellect is either 
theoretical or practical. The former issues no command as to 
what we should avoid or pursue and, although the latter does issue 
such commands, they are not necessarily obeyed. The analogy of 
the arts, too, shows that, in order to produce action, something 
else is required beyond the mere knowledge of what is to be 
pursued or avoided. Shall we say, then, that there are two motives 
to action, (i) desire and (2) the intellect which calculates moans to 
ends, the place of which latter in animals devoid of reason is taken 
by imagination? If so, how are the two connected? Desire is 
always of an end, and this end is the starting point for the calcula- 
tions of the practical intellect. Intellect and desire, then* are 
connected by the ultimate unmoved movcnt, the end of action. 
It is this which stirs desire, while intellect, assuming that the end 
can be realised, calculates the steps towards its attainment* Thus 
the physician whose aim is to cure an ague assumes this to be 
done, just as if he were trying to solve a geometrical problem, and 
then reasons backwards from the patient's recovery to the normal 
temperature which this implies, from the normal temperature to 
the production of heat or cold, and from that to some remedy at

INTRODUCTION. I Ixxi 

his command ; and thereupon, having reached the end of his 
calculations, he proceeds to act Hence the statement that there 
are two motives to action calls for qualification. Had there been 
two, they would have had some common character, but as a 
matter of fact intellect is never a motive apart from desire. On 
the other hand, desire does sometimes move to action in spite of 
reason. Desire is thus found in all forms of mental life. In reason 
it is rational wish, but there are also irrational desires, anger and 
appetite, or mere desire of pleasure. In fact, an appetitive faculty 
must be assumed in which Plato's anger and appetite are both 
included, and Aristotle says quite fairly that the soul may be 
divided into many faculties, any two of which are more distinct 
than these two of Plato. Wherever in the animal world there is 
sense-perception, there is also the feeling of pleasure and pain. The 
pleasurable prompts desire, the painful aversion, and the survival of 
sense-impressions, which is imagination in its lowest form, can 
prompt to desire no less than the present object in the moment of 
perception* For the intellect images take the place of present 
sensation. A conflict of desires may arise, for though reason will 
judge correctly, anger or appetite may be blinded. They may take 
apparent good for real good, or they may interpret good as the 
pleasure of the moment. Every desire, whether rational or 
irrational, implies a corresponding image of the object desired. 
Hence a distinction between images, according as they proceed 
wholly from sense (and this class of images alone belongs to 
irrational animals) or proceed from reason, calculation; in fact, 
deliberation. This latter class of images is peculiar to man. Yet 
even in man in the abnormal state of incontinence the irrational 
desire gets the better of reason and controls action. In order to ex- 
press the antecedents of action, whether of the normal or abnormal 
kind, Aristotle resorted to the analogy of the syllogism. From a 
universal major premiss and a particular minor a conclusion is 
inferred. For example, all men should take exercise, Callias is a 
man, ergo Callias should take exercise. His taking exercise is 
regarded as an inference from the premisses. It resembles the 
conclusion of a syllogism just in so far as a particular case is 
brought under a general rule. But this way of looking at the 
matter by no means ensures rational action or justifies the assump- 
tion that the intellect always calculates correctly, for incontinence 
has a syllogism of its own. For example, all sweet things are to be 
tasted, this thing before me is sweet: then, if you have the power 
and are not hindered, you cannot but at once put the conclusion 

e 2 



Ixxii INTRODUCTION. I 

(this is to be tasted) into practice. In this way the triumph of the 
irrational impulse and the sacrifice of the permanent good to the 
pleasure of the moment may equally be considered to bring a 
particular case under a general rule. In other words, although 
reason has a natural right and ought to prevail, experience shows 
that it is not always effective, even in beings endowed with reason, 
who look before and after. When impulsive action has been 
distinguished from deliberative and we are dealing with the latter 
only, since purpose is desire following upon deliberation, if the 
purpose is to be all it should be, both the calculation or reasoning 
must be true and the desire right, and the very same things must 
be assented to by the reason and pursued by the desire 1 . 

In the foregoing sketch I have been content to let Aristotle 
speak for himself, piecing together various utterances and putting 
the best construction I could on what is obscure and enigmatical in 
them, but refraining as a rule from criticism. Obviously he studied 
psychology as a philosopher and was chiefly interested in it as it 
bore upon philosophical problems. He exalted tlu* cognitive* 
clement, while his treatment of the emotions and the will is 
wholly inadequate, even if the Ethics and the R/tttwi? he called 
in to redress the balance. It is now contended that the science of 
psychology, which has made vast strides since these humble be- 
ginnings, must be based exclusively upon individual experience 
and be made independent of physiology. Whatever can he set 
down to the credit of Aristotle as a psychologist rests upon the 
opposite assumptions, fie approached his subject from the 
psychophysical standpoint, as it is called ; he had his own repre- 
sentative theory of perception, his own account of the gradual 
ascent from sense, through memory, to science: and reason. He 
coulcl not escape the errors and confusion incident to such ^-.sump- 
tions, if after all they are not ultimately valid. Thus we are 
brought face to face with grave metaphysical problems, Hut this 
is not the place to examine Aristotle's system as a whole, and 
without such an examination it is impossible to do justice either 
to his* theory of knowledge or to the treatise on the soul

INTRODUCTION. II. 

THE TEXT. 

The text of DC Anima rests mainly on the authority of a single 
good manuscript, cod. Parisiensis 1853, better known by the symbol 
E, given it by Bekker. Trendelenburg 2 , p. xvi, describes it thus ; 
saeculi decimi, membranaceus, eleganter et perspicue scriptus, 
vocibus non seiunctis sed inter se ligatis. Torstrik adds, p. viii : 
In eo igitur codice qui sunt de Anim& libri duabus manibus scripti 
sunt, antiquissirnis, elegantissimis, simillimis, sed duabus. Book I., 
Book III. and the fragments of a recension or paraphrase of Book IT., 
different from the vulgate (see pp. 164 sqq. infra), are in the same 
hand as the Physics, which cod. E also contains, and have 38 lines 
to the page. Book n. in a complete form and 4 in practically the 
same recension as all other manuscripts present is the work of 
another hand and has 48 lines to the page. Cod. E has been 
scrutinised by Bekker, Trendelenburg, Bussemaker, Pansch, Tors- 
trik, Bichl, Stapfer and Rodier. For further information respecting 
its peculiarities I refer my readers to Trend. 1 pp. viii, xxiii xliii, 
Trend. 2 pp. vi\ xiv xviii, Torstrik pp. ii, viii xv, Stapfer, Studia in 
Aristotelis de anima libros collate, especially pp. 4 13. In Book 
III. cod. E is mutilated, one leaf, which should have come between 
fol. 200 and fol. 201, is missing: it doubtless contained upon its 
76 lines the text from 430 a 24 fivwovevo^v to 431 b 16 e/cetva, 
or 84 of Bekker's lines. Further, the last leaf is also wanting, 
which should have contained from 434 a 31, the -6&v of pyOev, to 
the end, 435 b 25, or about 86 of Bekker's lines. The loss of these 
two leaves is serious, but is in some measure compensated by the 
fact that for the whole of Book TIL we have cod. L, Vaticanus 253, 
presenting a text which agrees more closely with that of cod. E 
than with that of the other extant manuscripts. Cod. L, which 
contains only the third book of De Anima, is described by Trend. 3 , 
p. ix, as follows : codex chartaceus, foliis quaternis minoribus, satis 
recens, cuius librarius interdum scripturae compendia male in- 
tellexit. Hauthalius codicem bombycinum perspicue et diligenter 



Ixxiv INTRODUCTION. II 

scriptum saeculi XIV esse litteris nobis significavit. A lection um 
praestantia (saepius enim cum vetustissimo cod ice (K) conscntit) 
antiquior quam recent for essc vidcatur. 

Besides codd. E and L Bekker collated six other codices of later 
date, which he indicated by the symbols S T U V W X, To these 
in what follows I shall give the name of the S-X group. The six 
have, so far as I know, never been scrutinised or collated by anyone 
since Bekker. Torstrik consulted the manuscript materials (pre- 
served in the Royal Library of Berlin), which Bekker collected 
for his edition, and was thus enabled from Bekker's own evidence 
to correct a few errors in Bckker's report of the readings of cod. S, 
as of cod. K (Torstrik, p. vii sq.: cf. Pfiilologus XII. 3, pp. 494 
530, XIII. i, pp. 204 206). The conclusion which Stapfcr 1 reached 
after careful study was that without a fresh collation of these 
six inferior codices the question of their mutual relationship anil 
pedigree could not be definitely settled, but that the result of such 
a fresh collation would not be worth the trouble expended upon 
it (Kritischc Studicn sit Aristoteles 1 Scltrift von tier Swh\ pp. 33 sq.). 
What is certain is that, while codd. KL go back to one common 
archetype, those belonging to the S-X group go back to another 
and a different common archetype. This result is established as 
follows : 

(A) Cod, K has two lacunae, each, I conjecture, a line of its 
archetype, which the other six codices supply* These lacunae 
are 405 b 25 sq. <?XXo ? /col rrjv tyvxfyv 0/40/009 $v T* r<nV<w and 
425 b 30 sq* rare 77 tear iivepyetav (Ixaf) apa ywerat teal &. Further* 
cod. E in 44 several places omits a single particle, an arliclt*, 
adjective, noun or verb, or even two (and once three) words, which 
are supplied by the group S-X. On the other hand, there are 22 
cases where cod, E has a slightly fuller text than the S-X group, 
the latter having omitted most frequently a particle, sometimes 
a noun or verb, and twice a couple of words (tyto/af 8*- 426 a 31, 
6 vov<s 429 b 13). 

(B) When we come to classify the readings in which c<xl 1C 
differs 9 from the S-X group, we sometimes find (i) a different word 
or (2) a different inflexion of the same word. The following are 
instances. In all cases the reading put first is the reading of 
cod. E, that put second is the reading of the S-X group, while

largely indebted to Stapfcr's two pamphlets.

Ixxvi INTRODUCTION. II 

From the instances given under (A) \ve may at once conclude 
that neither any single manuscript of the group S-X nor their 
common archetype was copied from cod, E, but we cannot directly 
infer that cod. E was not copied from the archetype of group 
S-X, for the omissions in cod. E, even the larger ones, are acci- 
dental. But the passages adduced under (B) sufficiently prove that 
cod. E is independent of the archetype of the group S-X. Chance 
might account for two or three or even a dozen variations, but 
not for 50. There can be no connexion between cod. E and the 
archetype of the group S-X. 

But had the six manuscripts of the group S-X a common 
archetype ? Yes : not because of the common omissions, which 
are few and insignificant, but because of such variants as the 
following: 403 a 19 crrj^elov : fAyvve^ the transposition of 404*1 5 
already noticed, 425 b I %oX^r/ on : f 6rt, %oX//, 426 b 2 \t7rapti : 
TriKpdy 434 a 3 XI/TTT;// /cal ffSovriv fyova'a : \VTTTJ fcal fj&oi'fy tVoucra. 
Taken singly, the manuscripts of the group S-X are full of 
mistakes. There are many cases where they diverge from each 
other in all manner of ways ; but, as soon as we get a reading 
or arrangement of the words which presents a noteworthy differ- 
ence from that of cod. E, they all agree. In fact, it has been 
proposed to use a fresh symbol for the agreement of the group 
S-X, as opposed to cod* E. 

But can we say how the manuscripts of the group S-X are 
related to each other? For example, in 403 b 2 UX have *Z&>s\ 
ST V W 6 Se or oSe. Possibly the genuine tradition of the arche- 
type may have come down to us in the numerical minority of the 
representatives of the group. It may be that four of the six 
represent one lost codex of equal value with the remaining two. 
Let us consider, besides 403 b 2 just mentioned, where U X have*

INTRODUCTION. II Ixxvii 

Cod. T and cod. W almost universally go together in the third 
book. 

Another circumstance confirms the conclusion that the six 
manuscripts of the group S-X are derived from a common arche- 
type. After cocl. E had been copied, it was subjected to much 
revision and many corrections were entered, either between the 
lines or in the margin. A great number of these, which on palaeo- 
graphical grounds are attributed to a second hand, agree in the 
main with the readings of the S-X group. Hence it may be 
inferred that the reviser, whether the original scribe or someone 
else 1 , collated cod. E with a manuscript which, whether it was 
or was not the archetype of the group S-X, agreed generally with 
the distinctive readings of that group. In other words, corn E 
agrees in the main with the manuscripts of the group S-X where 
they differ from the first hand 2 of E. Let us assume, then, that 
the text of Books i. and III. has come down by two independent 
traditions. The variations in Book II. are of minor importance, 
whether because, as Torstrik supposed, cod. E in the second Book 
follows a different authority from that which it follows in the other 
two Books, or because the two traditions never diverged to the 
same extent in this Book as in the others. It cannot be claimed 
that cither is infallible. To begin with (A) omissions and insertions: 
if we examine the several instances in detail, the presumption is 
that the omissions are due to carelessness. The good manuscript 
E has this peculiarity in common with the late manuscript P 1 of 
the Politics*^ that it is apt to omit small words. It would be 
absurd to prefer a text which omitted 4033 6 Se, 403 a 18 
40/b 9 ye (cf. 407 b 32, 409 a 30), 408 b 15 060-99, 408 b 19 

1 In Books I, and in. Stapfer distinguishes three hands E, E*, E 3 , admitting that E 2 
is hardly to be distinguished from E and that E 8 is the same hand in which Book u. is 
copied : '* Kae igitur [correctiones] plurimae inveniuntur in primo et tertio libro, aliquot in 
secundo. AHerius vero manus scripture, proxime accedit ad prioris manus similitudinem. 
Ktenim ab utrius calamo manaverit scriptura, solum cognosci potesl cum ex aliarum 
quaruttdam Httcraram forma, turn ex diphthongo *et' facillime concluditur... Accedit, ut 
secunda manus aliquoties litteras radcndo, prior nonnisi expungendo deleat. Tertiae vero 
mantis Htterarum ductus idem stint ac librarii secundi libri" (Stapfer, Stitdia, p. 4). 

tt See Stapfcr, JKrit. Stud. p. 34 ; ' Derselbe [der Archelypus von S T U V W X] gilt 
allgemein flir verloren. Auch ich war dieser Ansicht, bis eingehendere Studien liber 
die Korrckturen in E niich Irclehrten, dass die von zweiter Hand nach keiner anderen 
Vorlage gemacht sein konnen als nach diesem Archetypus. Die Grlinde hiefiir sind teils 
paJaographischer, teils kritischer Natur." 

3 Since E is of the tenth century, P 1 of the fifteenth, it is quite possible that the 
archetype from which Demetrius Chalcondylas derived his copy may have deserved the 
censure which Newman passe* upon it, vol. 11. p. Ivii, ni. p. vii sq. Class. Rev. vii.

these omissions are doubtless due to the same haste or care- 
lessness which has mangled the text by curtailment in 409 a 10, 
425 b 7, 428 b 3 sq., 432 a 2, as well as by the longer lacunae already 
enumerated. Only three times does it appear that cod. K is un- 
doubtedly right in its omissions; 426 b I, 429 b 8, 433 b 3. For 
my part, though I have not had the courage of my opinion, I 
think that in 428 b 2 fyaiverat, Se ^ real tyevSr) is an improvement 1 : 
while, if we compare 433 a 9 with 433 a 17, two passat;rs which 
ought to be similarly worded, the balance of probability surely 
inclines to the supposition that in both the scribe of 1C or of its 
archetype is at his old trick of omitting a small word, even though 
in the former passage all our other sources join in the error. On 
the other hand, cod. E seems redundant in 407 b 24, 411 b 4, 29, 
425 b 3, 429 b n, 1 3 (/;$*), 16: and that this, too, is due to care- 
lessness is very evident in the dittogniphy of Sto /cat 425 b 3 and 
the impossible article in 429 b x6, (B) A comparison, again, 
of the variations which depend either upon a different word {e.g. 
403 a 19 <rrjjuiiov : p,^vvei) or a different inflexion of the same word 
shows that, although E is undoubtedly the best manuscript, it has no 
decisive superiority over the common archetype of the S-X group. 
The text printed in this edition, which differs very little from Torstrik 
and still less from Biehl, agrees in this respect 23 times with cot!, 1C 
against the S-X group and 29 times with the latter against cud* 1C. 
On the other hand, out of 15 instances where the same words are 
differently arranged in cod. E and in the S-X group, I follow my 
predecessors in preferring the order of cod. 1C 12 times arid the 
order of the S-X group only 3 times, viz. 411 b 21, 433 a 9, 
433 b 18: though, as will be seen from my note on the last 
passage, I incline to think that there also the order given by 
cod. E may have been that of the original text Biehl himself, 
who of all editors adhered most closely to cod. 1C, sometimes 
departed from it, and I have gone still further in this direction, 
as in 402a 12, 402 a 19, 403 b 17, 407 a 26, 27, 408 a 21, 412,1 17, 
418 b 22, 420 a 4, 427 a 14, 428 b 4, 431 b 25, 26, 431 b 27, On 
the other hand, I return to the reading of cod, K in 404 b to, 
41 3 a 29 sq., 426 a 27, 433 b *7-

Trendelenburg and called by him P. Belger, however, preferred 
to denote it by y and has been followed by subsequent editors. 
It offers many peculiarities, which may sometimes be due to 
conjectural emendation or to the arbitrary selection of a scribe 
who was acquainted with the variations in older manuscripts. 
The other is Vaticanus 1339, from which Rabe published a 
collation of the second Book in 1891. Its symbol is P. 

Besides certain essays by Alexander of Aphrodisias 1 and his own 
treatise De Anima, in which he follows the lines of Aristotle's, we 
have two paraphrases, one by Themistius and one by Sophonias. 
These are not, however, entirely paraphrase : a large proportion of 
commentary is interspersed. We have also two commentaries, 
one by Simplicius, the other ostensibly by Philoponus. Hayduck, 
who has re-edited Philoponus, inclines to think (p. v) that the 
commentary on Book in. is not by the same author as that upon 
Books I. and II., and attributes it conjecturally to Stephanus, the 
author of the extant commentary on IIe/>l epfj^veia^. Four of 
these writers go back centuries beyond our oldest manuscript. 
Alexander lived at the end of the second century A.D., Themistius 
belongs to the latter half of the fourth, while Simplicius and Phi- 
loponus were contemporaries in the reign of Justinian in the sixth 
century. Of Sophonias Fabricius 2 says: "Quis ille Sophonias 
fuerit et quando vixerit, non liquet." But an extant manuscript 
of his paraphrase is of the thirteenth or fourteenth century. The 
writings of Alexander, including his lost commentary on De Anima, 
were used by all his successors, and Simplicius and Philoponus 
betray an acquaintance with Themistius 3 . So far, then, the sug- 
gestion of a continuous tradition among the commentators of 
Aristotle may be readily admitted. But with Alexander our 
stream of tradition stops : a gap of five centuries separates him 
from Aristotle and Theophrastus. It is a perfectly gratuitous 
assumption that these later commentators represent the unbroken 
tradition of the Peripatetic School 4 , especially as Alexander is the

Ixxx INTRODUCTION. II 

only one of them who can be reckoned as a genuine Peripatetic. 
For the interpretation and criticism of Aristotle in the earliest 
days of the school our only authority is Priscianus Lydus, a con- 
temporary of Simplicius and Philoponus, who wrote Jklctaphrasis 
in Theopkrastum. A portion of this is preserved and was edited 
by By water for the Supplementitm Aristoteliciint. 

What aid, then, do these testimonia furnish to the text ? From 
the nature of the case they must be subsidiary to ancient manu- 
scripts, A paraphrast may indeed be content to repeat his author 
without change, as Themistius frequently does. But his main 
object is to render the meaning clear, and the freedom with which, 
in the pursuance of this object, he varies either the actual words 
or the arrangement of the words and sentences of his author must, 
even under the most favourable circumstances, render him a very 
unsafe guide to the reconstruction of the text. If anyone thinks 
this a harsh judgment, let him consider what sort of an idea we 
should have of the text of this treatise, -.u|.|n,siu- the manuscripts 
and commentaries had been lost and only Themistius and Sopho- 
nias preserved. The problem of determining what text or texts 
the paraphrast had before him is analogous to the problem of 
determining the reading of the manuscript or manuscripts used by 
William of Moerbckc when he made his Latin translation, \Ve 
never can be sure that the paraphrast or translator confined him- 
self to a single manuscript In the particular case of Sophonias, 
however, the difficulty of this problem is greatly diminished. The 
attention bestowed upon him by Trondclonburjf, Torstrik, llayduek 
and Stapfor 1 has established this result, that his paraphrase agrees 
more nearly with cod. K than with any other of our manuscripts. 
The case of Themistius, Simplicius and Philoponus is different 
A study of the critical notes in this edition will show that tlu:ir 
evidence, such as it is, favours sometimes cod. K ami at other 
times the readings of the S-X group. Sometimes, as may he seen 
from my notes on ipo a 4, the words of Themistius suggest one 
reading, but can be shown to be in all probability an intentional 
variation upon the other. The evidence to be obtained from the 
commentaries of Simplicius and Philoponus must in each case 
be weighed independently of the prefixed lemma. I heartily 
endorse the judgment of Torstrtk, p. vi : Philoponi ct Simplicii 

d nullius sunt rnomenti. He adds ; pertinent enim ad deterioris

familiae codices: licebatque eos negligere uno excepto loco Sed 
quum in Philoponi commentario passim natarent quaedam pyrd 
antiquiora et librariorum errore cum ipsa interpretatione com- 
mixta, haec exscripsi...cluabus de causis : prirnum quod habent 
quaedam bona : deinde ne nocerent: possunt enim facile pro iis 
haberi quae ipse Philoponus apud Aristotelem legerit. It is by 
no means certain that the lemma comes from the commentator 
at all : at most, he was probably content for brevity to indicate 
the first words and the last, with ea>? TOV interposed, or the first 
words followed by fcal ra 6^7)9, a practice which may still occasion- 
ally be detected in Simplicius, e.g. in Phys. 50, 5; 113, 20; 
114, 23 ; 440, 18; 935, 21 ; 1220, 27; l)e Anima 71, 11 sq.; 76, 13; 
93> r 5; 99> 5; ir >3> 2 7 : *9 2 > 22 5 cf. Philop. 431, 30. Subsequent 
copyists would expand the lemma 1 and piously supply the missing 
words from the best text of Aristotle available, without paying 
much regard to the indications of the commentary appended. 
This may be illustrated by a comparison of the Aldine editions 
of Simplicius and Philoponus with those recently edited by 
Hayduck. Trincavellus took his lemma with almost unfailing 
regularity from the Aldine edition of Aristotle. This fact is many 
times admitted by Hayduck in the course of his critical apparatus. 
Sec, e.g,, 315, 8; 374, 14; 3^> n; 394, 335 423* 2 SJ 4^5, *5 441, 12;

513, 31; 530, 28; 533, 14; 553, 17; 562, 5; 5^9, 25; 606, 3. But 
the same thinff is true of scores of passages where Hayduck has 
not pointed out the dependence of Trincavellus upon the Aldine, 
e.g., Philop. 179, 27 teal cm.; 181, 10 Se; 189, 8 7rapa\,oyd>Tpov ;

In all these cases the reading indicated must have come from the 
Aldine edition. It is not known from any manuscript of De 
Anima. Besides these differences, wherever the Aldine edition 
presents a peculiar order of words, this order is adopted by Trin- 
cavellus for the lemma of Philoponus. Asulanus made a similar 
use of the Aldine Aristotle for his edition of Simplicius, as may 

1 Trincavellus certainly did thiff. See Hayduck '$ critical notes on Philop. 21 1, 9; 288,

be seen from such instances as Simpl. I r, i ; 16, 31 ; 23, I ; 72, 17; 
82, 13 ; 271, ir. It is reasonable to infer that the same thing had 
been done before. For, even when the interference of the Aldine 
Aristotle is excluded, as it is in Hayduck's edition, lemma and in- 
terpretation are not always completely in accord. See for example 
Philop. 247, 13 ; 303, 31 ; 461, i, where Hayduck has adapted the 
lemma to suit the interpretation (as he has also clone e.g. 475, 28 ; 
534, 17 ; S74> 23); 553> *7- Compare also 45, 16 crw/xaro? with 46, 5 
rov o-obpaTo?', 1 86, 22 with 1 86, 24 ; 241, 16 with 241,21 and 261, 15 ; 
315, 7 with 315, 10 ; 348, 9 with 348, 10; 377, 32 with 378, i; 
425, i with 425, 22; 493, 15 with 493, 17; 560, 23 with 560, 26. 
The same tendency is seen in Themistius, and the last editor, 
Heinze, may be within his rights in altering the words or the 
order of the words in the paraphrase, in spite of his manuscripts, 
to ensure consistency with the context as a whole. Two notable 
instances are Them. 116, 1 8, where Hcinzc has substituted rr/XXa 
for Tavra, and Them. 58, 9 sq., where the alteration affects the 
order of the words. The commentators, then, as distinct from 
their copyists, are only to be held responsible for those variants 
which they cither distinctly attest fry Sirrr; 7} ypa<f>}j and the like 
or cite verbatim in the course of their interpretations. liven then 
caution is needed, since Philoponus is not alone in using <f>?j<rlv 
for a paraphrase and alteration of the Aristotelian text, much as 
Froudc may be said to have violated the sanctity of inverted 
commas when he printed between them his own abstracts of the 
documents he cited. All beyond this is matter of inference, often 
no doubt correct, but seldom sufficiently strong to stifle a feeling 
of uneasiness and uncertainty. For the rest, the readings of 
Simplicius and Philoponus, and indeed of Alexander and Plutarch 
in the few cases where we have information about them, do not 
seem uniformly to favour either cod. K or the S-X group, A 
few instances of bad readings arc appended. In 431 a 24 Simpli- 
cius read 6/j,Q<yevfj: if he had consulted Philoponus 56 1 6 sq. he 
might have found the right reading, ^ 6j*oyevfy* In 416 b 27 
Alexander and Simplicius read wof)v powv with the S-X group, 
while cod. K has* the support of Theorist ius and Sophonias, PhJlo- 
ponus knew both readings (288, 10 sq.). Where the manuscripts 
leave us in the lurch, it is seldom that a commentator helps us out, 
as Simplicius undoubtedly does in 403 b 12 by reading $, not f/ t and 
in 431 a 23 by reading &>, not ov. It is very significant that in 
both these cases the change required is a change of breathing, 
which would not be indicated in an uncial manuscript or older

DE ANIMA. BOOK I. 



Cognition Is in our eyes a thing" of beauty and worth, and this 1 
is true of one cognition more than another, either because it is 
exact or because it relates to more important and remarkable 
objects. On both these grounds we may with good reason claim 
a high place for the enquiry concerning the soul. It would seem, 
too, that an acquaintance with the subject contributes greatly to 
the whole domain of truth and, more particularly, to the study of 
nature, the soul being virtually the principle of all animal life. 
Our aim is to discover and ascertain the nature and 

The sub- 
ject of essence of soul and, in the next place, all the accidents

belonging to it ; of which some are thought to be 
attributes peculiar to the soul itself, while others, it is held, belong 
to the animal also, but owe their existence to the soul. But every- 2 
where and in every way it is extremely difficult to arrive at any 
trustworthy conclusion on the subject. It is the same here as in 
many other enquiries. What we have to investigate is the essential 
nature of things and the What. It might therefore be thought 
that there is a single procedure applicable to all the objects 
whose essential nature we wish to discover, as demonstration is 
applicable to the properties which go along with them : in that case 
we should have to enquire what this procedure is. If, however, 
there is no single procedure common to all sciences for defining 
the What, our task becomes still more difficult, as it will then be 
necessary to settle in each particular case the method to be 
pursued. Further, even if it be evident that it consists in demon- 
stration of some sort or division or some other procedure, there

is still room for much perplexity and error, when we ask from 
what premisses our enquiry should start,, for there are different 
premisses for different sciences ; for the science of numbers, for 
example, and plane geometry. 

The first thing necessary is no doubt to determine under which 3 
The f t ' ie summa genera soul comes and what it is; I mean, 

problems. whether it is a particular thing, i.e. substance, or is 
quality or is quantity, or falls under any other of the categories 
already determined. We must further ask whether it is amongst 
things potentially existent or is rather a sort of actuality, the 
distinction being all-important. Again, we must consider whether 4 
it is divisible or indivisible ; whether, again, all and every soul is 
homogeneous or not; and, if not, whether the difference between 
the various souls is a difference of species or a difference of genus : 
for at present discussions and investigations about soul would 
appear to be restricted to the human soul. We must take care not 5 
to overlook the question whether there is a single definition of soul 
answering to a single definition of animal; or whether 
a single there is a different definition for each separate soul, as for 

definition? j j i *u ' i 

horse and dog, man and god: animal, as the universal, 
being regarded either as non-existent or, if existent, as logically 
posterior. This is a question which might equally be raised in 
regard to any other common predicate. Further, on the assump- 6 
tion that there are not several souls, but merely several different 

parts in the same soul, it is a question whether we should 

Questions * 11 

of pro- begin by investigating soul as a whole or its several 
cc ure. p ar ts. And here again it is difficult to determine which 
of these parts are really distinct from one another and whether the 
several parts, or their functions, should be investigated first. Thus, 
e.g. should the process of thinking come first or the mind that 
thinks, the process of sensation or the sensitive faculty? And so 
everywhere else. But, if the functions should come first, again 7 
will arise the question whether we should first investigate the 
correlative objects. Shall we take, e.g., the sensible object before 
the faculty of sense and the intelligible object before the intellect? 
It would seem that not only is the knowledge of a thing's 8 

essential nature useful for discovering the causes of its 
* *ood attributes, as, e.g., in mathematics the knowledge of what 
definition. .^ me ant by the terms straight or curved, line or surface, 
aids MB in discovering to how many right angles the angles of a 
triangle are equal : but also, conversely, a knowledge of the 
attributes is a considerable aid to the knowledge of what a thing is.

CH. I 402 b 23 403 a 25 7 

For when we are able to give an account of all, or at any rate 
most, of the attributes as they are presented to us, then we shall 
be in a position to define most exactly the essential nature of the 
thing. In fact, the starting point of every demonstration is a 
definition of what something is. Hence the definitions which lead 
to no information about attributes and do not facilitate even con- 
jecture respecting them have clearly been framed for dialectic and 
are void of content, one and all. 

A further difficulty arises as to whether all attributes of the 9 
Soul and sou l are a l so shared by that which contains the soul or 
body. whether any of them are peculiar to the soul itself: a 

question which it is indispensable, and yet by no means easy, to 
decide. It would appear that in most cases soul neither acts nor is 
acted upon apart from the body : as, e.g., in anger, confidence, desire 
and sensation in general. Thought, if anything, would seem to be 
peculiar to the soul. Yet, if thought is a sort of imagination, or 
not independent of imagination, it will follow that even thought 
cannot be independent of the body. If, then, there be any of the 10 
functions or affections of the soul peculiar to it, it will be possible 
for the soul to be separated from the body : if, on the other hand, 
there is nothing of the sort peculiar to it, the soul will not be 
capable of separate existence. As with the straight line, so with 
it. The line, qitd straight, has many properties ; for instance, it 
touches the brazen sphere at a point ; but it by no means follows 
that it will so touch it if separated. In fact it is inseparable, since 
it is always conjoined with body of some sort. So, too, the 
attributes of the soul appear to be all conjoined with body : such 
attributes, viz., as anger, mildness, fear, pity, courage ; also joy, 
love and hate ; all of which are attended by some particular 
affection of the body. This indeed is shown by the fact that some- 
times violent and palpable incentives occur without producing in 
us exasperation or fear, while at other times we are moved by 
slight and scarcely perceptible causes, when the blood is up and 
the bodily condition that of anger. Still more is this evident from 
the fact that sometimes even without the occurrence of anything 
terrible men exhibit all the symptoms of terror. If this be so, 
the attributes are evidently forms or notions realised in matter.

Hence they must be defined accordingly : anger, for instance, as a 
certain movement in a body of a given kind, or some part or 
faculty of it, produced by such and such a cause and for such and 
such an end. These facts at once bring the investigation of soul, u 
Digres- whether in its entirety or in the particular aspect 
sion. described, within the province of the natural philosopher. 

But every such attribute would be differently defined by the 
physicist and the dialectician or philosopher. Anger, for instance, 
would be defined by the dialectician as desire for retaliation or 
the like, by the physicist as a ferment of the blood or heat 
which is about the heart : the one of them gives the matter, the 
other the form or notion. For the notion is the form of the thing, 
but this notion, if it is to be, must be realised in matter of a 
particular kind ; just as in the case of a house. The notion or 
definition of a house would be as follows : a shelter to protect us 
from harm by wind or rain or scorching heat ; while another will 
describe it as stones, bricks and timber ; and again another as the 
form realised in these materials and subserving given ends. Which 
then of these is the true physicist ? Is it he who confines himself 
to the matter, while ignoring the form? Or he who treats of the 
form exclusively ? I answer, it is rather he who in his definition 
takes account of both. What then of each of the other two ? Or 
shall we rather say that there is no one who deals with proper- 
ties which are not separable nor yet treated as separable, but 
the physicist deals with all the active properties or passive affec- 
tions belonging- to body of a given sort and the corresponding 
matter? All attributes not regarded as so belonging he leaves 
to someone else: who in certain cases is an expert, a carpenter, 
for instance, or a physician. The attributes which, though in- 
separable, are not regarded as properties of body of a given sort, but 
arc reached by abstraction, fall within the province of the mathe- 
matician : while attributes which are regarded as having separate 
existence fall to the first philosopher or metaphysician. But 
to return to the point of digression. We were saying that the 
attributes of the soul are as such, I mean, as anger and 
fgg^ inseparable from the physical matter of the animals 
to which they belong, and not, like line and surface, separable in 
thought.

In our enquiry concerning soul it is necessary to state the 2 
problems which must be solved as we proceed, and at the same 
Thc time to collect the views of our predecessors who had 

theorfe* anything to say on the subject, in order that we may 

adopt what is right in their conclusions and guard against 
their mistakes. Our enquiry will begin by presenting what are 2 
commonly held to be in a special degree the natural attributes of 
soul. Now there are two points especially wherein that which is 
animate is held to differ from the inanimate, namely, motion and 
the act of sensation : and +hese are approximately the two charac- 
teristics of soul handed down to us by our predecessors. There are 
some who maintain that soul is preeminently and primarily the 
soui cause of movement. But they imagined that that which 

because * s not i tse lf * n motion cannot move anything else, and 
movent. ^hus they regarded the soul as a thing which is in 
motion. Hence Democritus affirms the soul to be a sort of fire or 3 
The heat. For the "shapes" or atoms are infinite and those 

atomists. which are spherical he declares to be fire and soul : they 
may be compared with the so-called motes in the air, which are 
seen in the sunbeams that enter through our windows. The 
aggregate of such seeds, he tells us, forms the constituent elements 
of the whole of nature (and herein he agrees with Leucippus), 
while those of them which are spherical form the soul, because 
such figures most easily find their way through everything and, 
beiny themselves in motion, set other things in motion. The 
atomists assume that it is the soul which imparts motion to 
animals. It is for this reason that they make life depend upon 
respiration. For, when the surrounding air presses upon bodies 
and tends to extrude those atomic shapes which, because they are 
never at rest themselves, impart motion to animals, then they are 
reinforced from outside by the entry of other like atoms in respira- 
tion, which in fact, by helping to check compression and solidification, 
prevent the escape of the atoms already contained in the animals ; 
and life, so they hold, continues so long as there is strength to do 
this. The doctrine of the Pythagoreans seems also to contain the 4 
certain same thought. Some of them identified soul with the 

motes in the air, others with that which sets these motes

in motion : and as to these motes it has been stated that they are 
seen to be in incessant motion, even though there be a perfect calm. 
The view of others who describe the soul as that which moves itself 
tends in the same direction. For it would seem that all these thinkers 
regard motion as the most distinctive characteristic of the soul. 
Everything else, they think, is moved by the soul, but the soul is 
moved by itself : and this because they never see anything cause 
motion without itself being in motion. Similarly the soul is said to 5 
be the moving principle by Anaxagoras and all others who have held 
Anaxa- that mind sets the universe in motion ; but not altogether 
goras. j n the same sense as by Democritus. The latter, indeed, 

absolutely identified soul and mind, holding that the presentation 
to the senses is the truth: hence, he observed, Homer had well 
sung of Hector in his swoon that he lay 'with other thoughts.' 
Democritus, then, does not use the term mind to denote a faculty 
conversant with truth, but regards mind as identical with soul. 
Anaxagoras/ however, is less exact in his use of the terms. In 
. . many places he speaks of mind as the cause of goodness 

His view *>.r- o 

ambigu- and order, but elsewhere he identifies it with the soul : as 
where he attributes it to all animals, both great and 
small, high and low. As a matter of fact, however, mind in the 
sense of intelligence would not seem to be present in all animals 
alike, nor even in all men. 

Those, then, who have directed their attention to the motion of 6 
Soul as t ^ lc an i mate being, conceived the soul as that which is 
cognitive, most capable of causing motion : while those who laid 

derived * & 

from the stress on its knowledge and perception of all that exists 
identified the soul with the ultimate principles, whether 
they recognised a plurality of these or only one. Thus Empedocles 
Empcdo- compounded soul out of all the elements, while at the 
clett * same time regarding each one of them as a soul. His 

words arc "With earth we see earth, with water water, with air 
bright air, but ravaging fire by fire, love by love, and strife by

structs the soul out of the elements. Like, he there 

Plato. 

maintains, is known by like, and the things we know are 
composed of the ultimate principles. In like manner it was 
explained in the lectures on philosophy, that the self-animal or 
universe is made up of the idea of One, and of the idea-numbers 
Two, or primary length, Three, primary breadth, and Four, primary 
depth, and similarly with all the rest of the ideas. And again this 
has been put in another way as follows : reason is the One, know- 
ledge is the Two, because it proceeds by a single road to one 
conclusion, opinion is the number of a surface, Three, and sensation 
the number of a solid, Four. In fact, according to them the 
numbers, though they are the ideas themselves, or the ultimate 
principles, are nevertheless derived from elements. And things 
are judged, some by reason, others by knowledge, others again 
by opinion and others by sensation : while these idea-numbers 
are forms of things. And since the soul was held to be thus 8 
The self- cognitive as well as capable of causing motion, some 
moving: thinkers have combined the two and defined the soul as a 

number. 

self-moving number. 

But there are differences of opinion as to the nature and number of 9 
various ^hz ultimate principles, especially between those thinkers 
w ^ ma ^ e t ' ie principles corporeal and those who make 
them incorporeal : and again between both of these and 

spending 

theories of others who combine the two and take their principles 

from both. But, further, they differ also as to their 10 
number : some assuming a single principle, some a plurality. And, 
when they come to give an account of the soul, they do so in strict 
accordance with their several views. For they have assumed, not 
unnaturally, that the soul is that primary cause which in its own 
nature is capable of producing motion. And this is why some n 
identified soul with fire, this being the element which is made up of 
the finest particles and is most nearly incorporeal, while further it 
is preeminently an element which both moves and sets other things 
in motion. Democritus has expressed more neatly the reason for 12 
each of these facts. Soul he regards as identical with mind, and 
this he makes to consist of the primary indivisible bodies and 
considers it to be a cause of motion from the fineness of its particles 
and their shape. Now the shape which is most susceptible of

CH. 2 405 a 12 405 b 8 17 

motion is the spherical ; and of atoms of this shape mind, like fire, 
consists. Anaxagoras, while apparently understanding by mind 13 
something different from soul, as we remarked above, really treats 
both as a single nature, except that it is preeminently mind which 
he takes as his first principle ; he says at any rate that mind 
alone of things that exist is simple, unmixed, pure. But he refers 
both knowledge and motion to the same principle, when he says 
that mind sets the universe in motion. Thales, too, apparently, 14 
judging from the anecdotes related of him, conceived 
soul as a cause of motion, if it be true that he affirmed 
the loadstone to possess soul, because it attracts iron. Diogenes, 15 
however, as also some others, identified soul with air. 

Diogenes. 

Air, they thought, is made up of the finest particles and 

is the first principle : and this explains the fact that the soul knows 

and is a cause of motion, knowing by virtue of being the primary 

element from which all else is derived, and causing motion by the 

extreme fineness of its parts. Heraclitus takes soul for his first 16 

principle, as he identifies it with the vapour from which 

he derives all other things, and further says that it is the 

least corporeal of things and in ceaseless flux ; and that it is by 

something in motion that what is in motion is known ; for he, like 

most philosophers, conceived all that exists to be in motion. 

Alcmaeon, too, seems to have had a similar conception. For soul, 17 

he maintains, is immortal because it is like the beings 

which are immortal ; and it has this attribute in virtue of 

being ever in motion : for he attributes continuous and unending 

motion to everything which is divine, moon, sun, stars and the 

whole heaven. Among cruder thinkers there have been some, like 18 

Hippon, who have even asserted the soul to be water. The reason 

for this view seems to have been the fact that in all 

xppon. animals the seed is moist : in fact, Hippon refutes those 

who make the soul to be blood by pointing out that the seed is not 

blood, and that this seed is the rudimentary soul. Others, again, 19 

like Critias, maintain the soul to be blood, holding that it is 

sentience which is most distinctive of soul and that this 

is due to the nature of blood. Thus each of the four 

elements except earth has found its supporter. Earth, however,

has not been put forward by anyone, except by those who have 
explained the soul to be derived from, or identical with, all the 
elements. 

Thus practically all define the soul by three characteristics, 20 
motion, perception and incorporeality ; and each of these 
c h arac teristics is referred to the ultimate principles. 
Hence all who define soul by its capacity for knowledge either 
make it an element or derive it from the elements, being on this 
point, with one exception, in general agreement. Like, they tell 
us, is known by like; and therefore, since the soul knows all 
things, they say it consists of all the ultimate principles. Thus 21 
those thinkers who admit only one cause and one element, as fire 
or air, assume the soul also to be one element ; while those who 
admit a plurality of principles assume plurality also in the soul. 
Anaxagoras alone says that mind cannot be acted upon and has 22 
nothing in common with any other thing. How, if such be its 
nature, it will know anything and how its knowledge is to be 
explained, he has omitted to state; nor do his utterances afford 
a clue. All those who introduce pairs of opposites among their 23 
principles make the soul also to consist of opposites; while those 
who take one or other of the two opposites, either hot or cold 
or something else of the sort, reduce the soul also to one or other 
of these elements. Hence, too, they etymologise according to their 
theories ; some identify soul with heat, deriving !fiv from eo>, and 
contend that this identity accounts for the word for life ; others 
say that what is cold is called soul from the respiratory process 
and consequent " cooling down," deriving tfrvxtf from ^tJ%w. Such, 
then, are the views regarding soul which have come down to us 
and the grounds on which they are held. 

We have to consider in the first place the subject of motion. 3 
criticism ^ or> un '- ess I am niistaken, the definition of soul as the 
of the self-moving, or as that which is capable of self-motion, 

soul is misrepresents its essential nature : nay, more ; it is quite 
impossible for soul to have the attribute of motion at 
all. To begin with, it has been already stated that a thing may 2 
cause motion without necessarily being moved itself. A thing 
is always moved in one of two ways; that is, either indirectly,

through something else, or directly, of and through itself. We 
say things are moved through something else when they are in 
something else that is moved : as, for instance, sailors on board 
a ship : for they do not move in the same sense as the ship, for 
the ship moves of itself, they because they are in something else 
which is moved. This is evident if we consider the members of 
the body : for the motion proper to the feet and so to men also 
is walking, but it is not attributable to our sailors in the case 
supposed. There being thus two senses in which the term "to be 
moved" is used, we are now enquiring" whether it is of 

Is the soul ' * 

moved and through itself that the soul is moved and partakes 

Perse? *> ^ 

of motion. 

Of motion there are four species, change of place or loco- 3 
motion, change of quality or alteration, diminution and augmenta- 
species of tion. It is, then, with one or more or all of these 
motion. species that the soul will move. If it is not indirectly 
or per acddens that it moves, motion will be a natural attribute of 
soul ; and, if this be so, it will also have position in space, since 
all the aforesaid species of motion are in space. But, if it be the 
essential nature of soul to move itself, motion will not be an 
accidental attribute of soul, as it is of whiteness or the length of 
three cubits ; for these are also moved, but per accidens, viz. by the 
motion of the body to which these attributes belong. This, too, is 
why these attributes have no place belonging to them; but the soul 
will have a place, if indeed motion is its natural attribute. 

Further, if it moves naturally, then it will also move under 4

it moves by constraint But what is meant by constrained motions 
or states of rest of the soul it is not easy to explain, even though 
we give free play to fancy. Again, if its motion tends upward, 5 
it will be fire ; if downward, earth ; these being the motions proper 
to these natural bodies. And the same argument applies to 
directions of motion which are intermediate. 

Again, since it appears that the soul sets the body in motion, 6 
it may reasonably be supposed to impart to it the motions which 
it has itself: and, if so, then conversely it is true -to say that the 
motion which the soul has itself is the motion which the body

has. Now the motion of the body is motion in space : therefore 
the motion of the soul is also motion in space, whether the whole 
soul so move, or only the parts, the whole remaining at rest. But, 
if this is admissible, the soul might also conceivably quit the body 
and re-enter; and this would Involve the consequence that dead 
animals may rise again. 

To return now to motion per accidens^ soul might certainly 7 
thus be moved by something external as well : for the animal 
might be thrust by force. But a thing which has self-motion as 
part of its essential nature cannot be moved from without except 
incidentally ; any more than that which is good in itself can be 
means to an end, or that which is good for its own sake can be so 
for the sake of something else. But, supposing the soul to be 
moved at all, one would say that sensible things would be the 
most likely to move it. 

Again, even if soul does move itself, this is equivalent to saying 8 
that it is moved ; and, all motion being defined as displacement 
of the thing moved qua moved, it will follow that the soul will 
be displaced from its own essential nature, if it be true that its 
self-movement is not an accident, but that motion belongs to the 
essence of soul in and of itself. Some say that the soul in fact 9 
Democri- moves the body, in which it is, in the same way in which 
tus * it moves itself. So, for example, Democritus ; and herein 

he resembled Philippus, the comic poet, who tells us that Daedalus 
endowed the wooden Aphrodite with motion, simply by pouring 
in quicksilver : this is very similar to what Democritus says. For 
according to him the spherical atoms, which from their nature can 
never remain still, being moved, tend to draw the whole body 
after them and thus set it in motion. But do these same atoms, 10 
we shall ask in our turn, produce rest, as well as motion? How 
this should be, it is difficult, if not impossible, to say. And, 
speaking generally, it is not in this way that the soul 
motion is would seem to move the animal, but by means of purpose 

purposive, _ - , , - . . 

of some sort, that is, thought. 

In the same way the Platonic Timaeus explains on physical n 
The grounds that the soul sets the body in motion, for by its 

'Tunaeus.' own motion it sets the body also in motion, because it 
is closely interwoven with it. For when it had been made out of

the elements and divided in harmonical ratios in order that it 
might have a native perception of proportion and that the universe 
might move in harmonic revolutions, he, the creator, proceeded to 
bend the straight line into a circle; and then to split the one circle 
into two, intersecting at two points ; and one of the two circles he 
split into seven, the revolutions of heaven being regarded as the 
motions of the soul. In the first place, it is not right to call 12 
criticism the soul a magnitude. For by the soul of the universe 
m detail. Timaeus clearly intends something of the same sort as 
what is known as mind : he can hardly mean that it is like the 
sensitive or appetitive soul, whose movements are not circular. 
But the thinking mind is one and continuous in the same sense 13 
as the process of thinking. Now thinking consists of thoughts. 
But the unity of these thoughts is a unity of succession, the unity 
of a number, and not the unity of a magnitude. This being so, 
neither is mind continuous in this latter sense, but either it is 
without parts or else it is continuous in a different sense from an 
extended magnitude. For how can it possibly think if it be 
a magnitude ? Will it think with some one or other of its parts : 
such parts being taken either in the sense of magnitudes or in the 
sense of points, if a point can be called a part ? If it be with 14 
parts in the sense of points, and there is an- infinity of these, 
clearly mind will never reach the end of them ; while, if they be 
taken in the sense of magnitudes, mind will have the same thoughts 
times without end. But experience shows that we can think a 
thought once and no more. Again, if it be enough for the soul 
to apprehend with one or other of its parts, what need is there for 
it to be moving in a circle or to have magnitude at all ? But, if 
it is necessary to thought that the mind should bring the whole 
circle into contact, what does the contact of the several parts 
mean ? Again, how will it think that which is divisible by means 
of that which is without parts, or that which is without parts 
by means of that which is divisible? It must be mind which 
is meant by the circle in question. For when mind moves it 
thinks ; when a circle moves it revolves. If, then, thought 15 
is a revolution, the circle which has such a revolution must

be mind. But then it will go on thinking of something for ever, 
for this is required by the eternity of the revolution. To practical 
thinking there are limits, for it always implies an external end; 
while speculative thinking is determined in the same way as the 
logical explanations which express it Now every explanation 
consists either in definition or in demonstration. But demonstra- 
tions have a premiss for starting-point and reach a kind of goal 
in the inference or conclusion; while, even if they never reach 
a conclusion, at all events they do not revert to the starting-point, 
but with the aid of a succession of middle terms and extremes 
advance in a straight line. But circular movement returns to the 
point from which it started. Definitions, too, are all determinate. 
Besides, if the same revolution recurs again and again, the mind 16 
will be obliged to think the same thing again and again. Further, 17 
it is a sort of rest or coming to a halt, and not motion, which 
thinking resembles : and we may say the same of the syllogism. 
Nor, again, will that which does not move easily, but under con- 18 
straint, even realise happiness. If the motion of soul be not its 
essence, it will be an unnatural motion. And the entanglement of 19 
the mind in the body without the possibility of release is painful ; 
nay, it is to be avoided, if indeed it is really better for mind to 
Jt>e independent of body, a view commonly expressed and widely 
accepted. Also it is not clear why the heaven revolves in a circle ; 20 
seeing that circular motion is neither implied by the essence of 
soul (that form of movement being indeed merely accidental to it), 
nor due to the body : on the contrary it is rather the soul which 
causes the motion of the body. Besides, we are not even told that 21 
it is better so: yet surely the reason why God made the soul 
revolve in a circle ought to have been that movement was better 
for it than rest, and this form of movement better than any other. 

But such an enquiry as this belongs more appropriately to 
a different subject : so let us dismiss it for the present. We may, 22 
however, note here another absurdity which is involved in this as 
in most other theories concerning the soul. They attach

seem to be required, as it is owing to their relationship that the

one acts, the other is acted upon, that the one is moved, and 
the other causes it to move; and between two things taken at 
random no such mutual relations exist. The supporters of such 23 
theories merely undertake to explain the nature of the soul. Of 
the body which is to receive it they have nothing more to say : 
just as if it were possible for any soul taken at random, according 
to the Pythagorean stories, to pass into any body. This is absurd, 
for each body appears to have a distinctive form or shape of its 
own. It is just like talking of a transmigration of carpentry 
into flutes : for the craft must employ the right tools and the soul 
the right body. 

There is yet another opinion concerning soul which has come 4 
down to us, commending itself to many minds as readily as any 
that is put forward, although it has been severely criticised even 
in the popular discussions of the present day. The soul 

The theory . i , i . , r , /. , 

of har- is' asserted to be a kind of harmony, for harmony is 

mony ' on this view a blending or combining of opposites, 

and the components of the body are opposites. And yet this 2 
harmony must mean either a certain proportion in the components 
or else the combining of them ; and the soul cannot possibly be 
either of these. Furthermore, to cause motion is no attribute of 3 
a harmony : yet this function more than any other is all but 
universally assigned to soul. Again, it is more in harmony with 4 
the facts to apply the term harmony to health or bodily excellence 
generally than to soul, as is very clearly seen when we try to 
assign to a harmony of whatever kind the affections or functions 
of the soul : it is difficult to harmonise them. 

Further, if we use the word harmony with a twofold appli- 5 
cation ; first, and in its most natural sense, of those magnitudes 
T which have motion and position, to denote the combining 

meanings o f them into a whole, when they are so closely fitted 
term har- together that they do not admit between them anything 
mony " of the same kind; and then in a secondary sense to denote 

the proportion subsisting between the components of a mixture: in 
neither sense is it reasonable to call soul a harmony. The view which 
regards it as a combining of the parts of the body is singularly

open to criticism. For there are many combinings of the parts, 
and they combine in many ways. What part, then, is that whose 
combining with the rest we must assume to be the intellect, and 
in what way does it combine? Or again, what of the sensitive 
and appetitive faculties? But it is equally absurd to regard the soul 6 
as the proportion determining the mixture. For the elements are 
not mixed in the same proportion in flesh as in bone. Thus it 
will follow that there are many souls, and that, too, all over the 
body, if we assume that all members consist of the elements 
variously commingled and that the proportion determining the 
mixture is a harmony, that is, soul. This is a question we might 7 
Empe- as k Empedocles; who says that each of the parts is 
docies. determined by a certain proportion. Is the soul, then, 

this proportion, or is it rather developed in the frame as something 
distinct ? And, further, is it a mixture at random or a mixture in 
the right proportion which he ascribes to Love : and, if the latter, 
is Love the proportion itself or something other than the proportion 
and distinct from it? Such, then, are the difficulties involved in 
this view. On the other hand, if soul is something distinct from 8 
Difficulties ^e m i x ture, how comes it that it is destroyed simul- 
invoived taneously with the disappearance of the quiddity of the 
ing the flesh and of the other parts of the animal ? And, further, 
eory ' assuming that each of the separate parts has not a soul 
of its own, unless the soul be the proportion of their admixture, 
what is it that perishes when the soul quits the body? 

From what has been said it is clear that the soul cannot be 
Conciu- a harmony and cannot revolve in a circle. But inci- 9 
sion. dentally it can, as we have seen, move and set itself in 

motion : for instance, the body in which it is may move, and be 
set in motion by the soul : otherwise it cannot possibly move from 
place to place. The question whether the soul is moved would 10 

more naturally arise in view of such facts as the 
stated and following. The soul is said to feel pain and joy, con- 
answer e . fj c i ence anc j f ear? an< f[ again to be angry, to perceive and 
to think ; and all these states are held to be movements : which 
might lead one to infer that soul itself is moved. But this is no 11 
necessary inference. For suppose it ever so true that to feel pain

CH. 4 408 b 6 408 b 33 33 

or joy and to think are movements, that to experience each of 
these is to be moved and that the movement is due to the soul : 
suppose that to be angry, for instance, or to be afraid means 
a particular movement of the heart, and that to think means 
a movement of this or of some other part, some of these move- 
ments being movements of locomotion, others of qualitative change 
(of what sort and how produced does not concern us here): yet, 12 
even then, to speak of the soul as feeling anger is as if one should 
say that the soul weaves or builds. Doubtless it would be better 
not to say that the soul pities or learns or thinks, but that the man 
does so with the soul : and this, too, not in the sense that the motion 
occurs in the soul, but in the sense that motion sometimes reaches 
to, sometimes starts from, the soul. Thus, sensation originates in 
particular objects, while recollection, starting from the soul, is 
directed towards the movements or traces of movements in the 
intellect: sense-organs. But intellect would seem to be developed 13 
an^m- ve * n us as a self-existing substance and to be imperishable, 
perishable. For, if anything could destroy it, it would be the feeble- 
ness of age. But, as things are, no doubt what occurs is the same 
as in the case of the sense-organs. If an aged man could procure 
an eye of the right sort, he would see just as well as a young 
man. Hence old age must be due to an affection or state not 
of the soul as such, but of that in which the soul resides, just as is 
the case in intoxication and disease. In like manner, then, thought 14 
and the exercise of knowledge are enfeebled through the loss of 
something else within, but are in themselves impassive. But 
reasoning, love and hatred are not attributes of the thinking 
faculty but of its individual possessor, in so far as he possesses 
it. Hence when this possessor perishes, there is neither memory 
nor love: for these never did belong to the thinking faculty, 
but to the composite whole which has perished, while the intellect 
is doubtless a thing more divine and is impassive. 

From the foregoing it is clear that the soul is incapable of 15 
motion; and, if it is not moved at all, clearly it does not move 
criticism itself. Now of all the views that have been put forward 16 
the sltf- by far the most irrational is that which makes the soul 
Simbel a self-moving number. Its supporters are involved in

many impossibilities, not only in those which arise from attributing 
motion to the soul, but also in others of a special character 
due to calling it a number. For how are we to conceive of a unit, 
a thing which is without parts or differences, as in motion ? By 
what would it be moved, and in what way ? For if it is capable 
of imparting motion as well as of being moved, it must admit 
differences. Further, since they say that a line by its motion gene- 17 
rates a surface and that a point by its motion generates a line, the 
movements of the units will also be lines, for a point is a unit 
having position. But the number of the soul must, from the 
nature of the case, be somewhere and have position. Again, if 18 
you subtract a number or unit from a number, a different number 
remains : whereas plants and many animals continue to live when 
divided and seem to have specifically the same soul in each seg- 
ment. Besides, it would seem to make no difference whether we 19 
say units or tiny particles. For if the little round atoms of 
Democritus be converted into points and only their sum-total be ' 
retained, in such sum-total there will still be a part which moves 
and a part which is moved, just as there is in that which is 
extended. The truth of this statement does not depend upon the 
size of the atoms, whether great or small, but upon the fact that 
there is a sum-total or quantity of them. Hence there must be 
something to set the units in motion. But if in the animal the 
part which causes motion is the soul, then it is so likewise in 
the number : so that it will not be both that which causes motion 
and that which is moved which is the soul, but that which causes 
motion only. How then can this cause of motion be a unit ? 20 
For if it were so there must be some difference between it and 
the other units. But what is there to differentiate points which 
are units, except position ? If, then, the units, that is the points, 
in the body are distinct from the units of soul, the units of soul 
will be in the same place as the points, for each unit will occupy 
the space of a point. And yet if two things can be in the same 
place, why not an infinite number ? When the place which things 
occupy is indivisible, the things themselves are also indivisible. 
If, on the other hand, the number of the soul consists of the 21 
points in the body, or if the soul is the number of such points, 
why are not all bodies possessed of soul ? For in all bodies there

would seem to be points : nay, an Infinity of points. And, further, 22 
how can the points be separated and set free from the bodies to 
which they belong ; unless, indeed, we are prepared to resolve lines 
into points ? 

It comes to this, then, as we have said, first, that this view 5 
The ob- coincides with that which makes of the soul a body 
composed of fine particles ; next, that its agreement 



with Democritus as to the manner in which he makes 
the body to be moved by the soul gives it an especial absurdity of 
its own. If the soul resides in the whole sentient body, on the 
assumption that the soul is a sort of body it necessarily follows 
that two bodies occupy the same space. Those who call the soul 
a number have to assume many points in the one point, or else 
that everything corporeal has a soul ; unless the number that 
comes to exist in the body is a different number, quite distinct 
from the sum of the points already present in the body. Hence it 2 
follows that the animal is moved by the number in the same way 
precisely as we said Democritus moved it For what difference 
does it make whether we speak of small round atoms or large 
units, or indeed of units in spatial motion at all ? Either way it is 
necessary to make the motion of the animal depend on the motion 
of these atoms or units. Such, then, are some of the difficulties 3 
confronting those who join motion and number: and there are 
many others, since it is impossible that the conjunction of motion 
with number should form even an attribute, much less the defi- 
nition, of soul This will be evident if we try to deduce from this 
definition the affections and functions of the soul ; its reasonings, 
perceptions, pleasures, pains, and so forth. For, as we said above, 
from the account given it is difficult even to divine what these 
functions are. 

Three modes of defining the soul have come down to us : 4 
some defined it as that which, in virtue of its self-motion, is most 
capable of causing motion ; others as the body which consists of 
the finest particles, or which is more nearly incorporeal than any- 
thing else. And we have pretty fully explained what difficulties 
and inconsistencies these views present It remains to consider 5 
what is meant by saying that the soul is composed of the

elements. Soul, we are told, is composed of the elements in 
soui is order that it may perceive and know each several thing. 
not a com- But this theory necessarily involves many impossibilities. 
the eie- For it is assumed that like is known by like ; which im- 
men s. plies that soul is identical with the things that it knows. 

These elements, however, are not all that exists : there are a great, 
or perhaps we should say rather, an infinite number of other things 
as well, namely, those which are compounded of the elements. 
Granted, then, that it is possible for the soul to know and to 6 
perceive the constituent elements of all these composite things, 
with what will it know or perceive the compound itself? I mean, 
what God or man is ; what flesh or bone is : and so likewise with 
regard to any other composite thing. For it is not elements taken 
anyhow which constitute this or that thing, but only 
i- those which are united in a given proportion or com- 
bination, as Empedocles says of bone: 

"Then did the bounteous earth in broad-bosomed crucibles 
win out of eight parts two from the sheen of moisture and four 
from the fire-god ; and the bones came into being all white/' 

It is therefore of no use for the elements to be in the soul, 
unless it also contains their proportions and the mode of combining 
them. For each element will know its like, but there will be 
nothing to know bone or man, unless these also are to be present 
in the soul : which, I need hardly say, is impossible. Who would 
ask if stone or man resides in the soul? And similarly with that 
which is good and that which is not good : and so for all the 
rest. 

Being, again, is a term which has various meanings, signifying 7 
sometimes the particular thing, sometimes quantity or quality or any 
other of the categories which have been already determined. Is the 
soul to be derived from all of these, or not? It cannot be: the 
general opinion is that there are no elements common to all the 
categories. Does the soul, then, consist of those elements alone 
which are the elements of substances ? How then does it know 
each of the other categories ? Or will they say that each summum 
genus has special elements and principles of its own, and that the 
soul is composed of these? Then soul will be at once quantity, 
quality and substance. But it is impossible from the elements of

quantity to derive substance or anything but quantity. These, 
then, and others like them are the difficulties which confront those 
who derive soul from all the elements. There is a further incon- 8 
sistency in maintaining- that like is unaffected by like and yet at 
the same time that like perceives like and knows like by like. 
But they assume that perceiving is a sort of being- acted upon or 
moved. And the same holds of thinking and knowing. 

Of the many problems and difficulties involved in holding with 9 
Empedocles that each thing is known through corporeal elements 
and by reference to its like \what has just been said is evidence\. 
For, it would seem, whatever within the bodies of animals consists 
entirely of earth, such as bones, sinews, hair, perceives nothing 
at all, and consequently cannot perceive its like ; as in consistency 
it should. Moreover, each one of the elemental principles will have 10 
a far larger share of ignorance than of intelligence ; there being 
many things of which it will be ignorant and only one which it will 
know : in fact, it will be ignorant of all besides that one. It 
follows, for Empedocles at any rate, that God is quite the most 
unintelligent of beings. There is one of the elements, viz. Strife, 
which he, and he alone, will not know, while mortal things, being 
composed of all the elements, will know them all. And in general, u 
seeing that everything is either an element or derived from one or 
more or all elements, why should not all things that exist have 
soul ? For they must certainly know one thing or some things 
or all. It might further be asked what it is that gives them unity. 12 
For the elements, at all events, correspond to matter. That other 
principle, whatever it be, which holds them together, is supreme. 
Yet it is impossible that anything should be superior to the soul 
and overrule it ; and still more impossible that anything should 
overrule intelligence. This, it may reasonably be held, has a 
natural priority and authority. Yet we are told that the elements 
are prior to all other things that exist. 

And it is characteristic, alike of those who derive the soul from 13 
the elements on the ground of perception and knowledge, and of 
those who define it as the thing most capable of causing motion,

that their assertions do not apply to soul in every form. For not 
all sentient beings can cause motion ; some animals are seen to be 
stationary in one place. And yet it is at all events a received view 
that this, namely, change of place, is the one form of motion which 
the soul imparts to the animal. Similarly with those who derive 
intelligence and the faculty of sense from the elements. For plants 
are found to live without any share in locomotion or sensation, and 
many animals to be destitute of thought. If we waive this point 14 
and assume intellect to be a part of the soul, and the faculty 
of sense likewise, even then their statements would not apply 
generally to all soul, nor to the whole of any one soul. The account 15 
The or. given in the so-called Orphic poems is open to the same 
cos- strictures. For the soul, it is there asserted, enters from 

^ e un j verse j n the process of respiration, being borne 
upon the winds. Now it is impossible that this should be so with 
plants or even with some animals, seeing that they do not all 
respire : a point which the upholders of this theory have over- 
looked. And if the soul is to be constructed out of the elements, 16 
there is no need to employ them all, the one of a pair of contraries 
being sufficient to discern both itself and its opposite. For by that 
which is straight we discern both the straight and the crooked, the 
carpenter's rule being the test of both. On the other hand that 
which is crooked is not a test of itself or of that which is straight 

There are some, too, who say that soul is interfused through- 17 
soul not out t ^ ie un i ver se : which is perhaps why Thales supposed 
thfoiTh a ^ ^ings to ke full of gods. But this view presents 18 
the uni- some difficulties. For why should the soul not produce 

an animal, when present in air or fire, and yet do so 
when present in the compounds of these elements : and that, too, 
though in the former case it is believed to be purer ? One might 19 
also enquire why the soul present in air is purer and more im- 
mortal than soul in animals. Whichever of the two suppositions 20 
open to us we adopt is absurd and irrational. To speak of fire 
or air as an animal is very irrational ; and on the other hand

not to call them animals, if they contain soul, is absurd. But 21 
it would seem that the reason why they suppose soul to be 
in these elements is that the whole is homogeneous with its 
parts. So that they cannot help regarding universal soul as also 
homogeneous with the parts of it in animals, since it is through 
something of the surrounding element being cut off and enclosed 
in animals that the animals become endowed with soul. But if the 
air when split up remains homogeneous, and yet soul is divisible 
into non-homogeneous parts, it is clear that, although one part 
of soul may be present in the air, there is another part which is 
not. Either, then, soul must be homogeneous, or else it cannot be 
present in every part of the universe, 

From what has been said it is evident that it is not because the 22 
soul is compounded of the elements that knowledge belongs to it, 
nor is it correct or true to say that the soul is moved. Knowledge, 23 
however, is an attribute of the soul, and so are perception, opinion, 
desire, wish and appetency generally ; animal locomotion also is 
produced by the soul ; and likewise growth, maturity and decay. 
unity of Shall we then say that each of these belongs to the whole 
soul - soul, that we think, that is, and perceive and are moved 

and in each of the other operations act and are acted upon with 
the whole soul, or that the different operations are to be assigned 
to different parts ? And what of life itself? Does it reside in any 
single one or more or all of these parts ? Or has it a cause 
entirely distinct ? Now some say that the soul is divisible and 24 
that one part of it thinks, another desires. What is it then which 
holds the soul together, if naturally divisible ? Assuredly it is not 
the body : on the contrary, the soul seems rather to hold the body 
together ; at all events, when it has departed, the body disperses 
in air and rots away. If, then, the unity of soul is due to some 
other thing, that other thing would be, properly speaking, soul. 
We shall need, then, to repeat the enquiry respecting it also, 
whether it is one or manifold. For, if it has unity, why not 
attribute unity to the soul itself at the outset? If, however, it 
be divisible, then again reason will go on to ask what it is that 
holds it together, and so the enquiry will go on to infinity. It 25 
might also be asked what power each of the parts of the soul

exercises in the body. For, if the entire soul holds together the 
whole body, then each of its parts ought properly to hold together 
some part of the body. But this seems impossible. For it is 
difficult even to conjecture what part the intellect will hold together 
or how it can hold any part together. It is found that plants, and 26 
among animals certain insects or annelida, live when divided, which 
implies that the soul in their segments is specifically, though not 
numerically, the same. At any rate, each of the two segments 
retains sentience and the power of locomotion for some time : that 
they do not continue to do so is not surprising, as they lack the 
organs requisite to maintain their nature. But none the less all 
the parts of the soul are contained in each of the two segments, 
and the two halves of the soul are homogeneous alike with one 
another and with the whole ; a fact which implies that, while the 
parts of the soul are inseparable from one another, the soul as a 
The soul whole is divisible. It would seem that the vital principle 27 
in plants. j n plants also is a sort of soul. For this principle is 
the only one common to plants and animals; and, while it can 
be separated from the sensitive principle, no being which has 
sensation is without it.

DE ANIMA. BOOK II. 

So much for the theories of soul handed down by our pre- 1 
1 . ,. decessors. Let us. then, make a fresh start and try to 

Soul in the ' 3 J 

widest determine what soul is and what will be its most com- 

application 

of the term prehensive definition. Now there is one class of existent 2 

things which we call silbstance, including under the 
term, firstly, matter, which in itself is not this or that ; secondly, 
shape or form, in virtue of which the term this or that is at once 
applied ; thirdly, the whole made up of matter and form. Matter 
is identical with potentiality, form with actuality. And there 
are two meanings of actuality : knowledge illustrates the one, 
exercise of knowledge the other. Now bodies above all things 3 
are held to be substances, particularly such bodies as are the work 
of nature; for to these all the rest owe their origin. Of natural 
bodies some possess life and some do not : where by life we mean 
the power of self-nourishment and of independent growth and 
decay. Consequently every natural body possessed of life must 
be substance, and substance of the composite order. And since 4 
in fact we have here body with a certain attribute, namely, the 
possession of life, the body will not be the soul : for the body is 
not an attribute of a subject, it stands rather for a subject of 
attributes, that is, matter. It must follow, then, that soul is 
substance in the sense that it is the form of a natural body having 
in it the capacity of life. Such substance is actuality. The soul,

therefore, is the actuality of the body above described. But the 5 
term 'actuality' is used in two senses; in the one it answers to 
knowledge, in the other to the exercise of knowledge. Clearly in 
this case it is analogous to knowledge : for sleep, as well as waking, 
implies the presence of soul ; and, whilst waking is analogous to 
the exercise of knowledge, sleep is analogous to the possession 
of knowledge without its exercise ; and in the same individual 
the possession of knowledge comes in order of time before its 
exercise. Hence soul is the first actuality of a natural body having 
in it the capacity of life. And a body which is possessed of organs 6 
answers to this description. We may note that the parts of plants, 
as well as those of animals, are organs, though of a very simple 
sort : for instance, a leaf is the sheath of the pod and the pod of 
the fruit. The roots, again, are analogous to the mouths of animals, 
both serving to take in nourishment. If, then, we have to make 
a general statement touching soul in all its forms, the soul will 
be the first actuality of a natural body furnished with organs. 
Hence there is no need to enquire whether soul and body are 7 
one, any more than whether the wax and the imprint are one ; 
or, in general, whether the matter of a thing is the same with that 
of which it is the matter. For, of all the various meanings borne 
by the terms unity and being, actuality is the meaning which 
belongs to them by the fullest right. 

It has now been stated in general terms what soul is, namely, 8 
substance as notion or form. And this is the quiddity of such 
and such a body. Suppose, for example, that any instrument, 
niustra- sa y> an axe > were a natural body, its axeity would be 



txon from its substance, would in fact be its soul. If this were 
taken away, it would cease, except in an equivocal sense, 



But the axe is after all an axe. For 
it is not of a body of this kind that the soul is the quiddity, 
that is, the notion or form, but of a natural body of a particular 
sort, having in itself the origination of motion and rest. 

Further, we must view our statement in the light of the parts of 9 

the body. For, if the eye were an animal, eyesight 
sight of an would be its soul, this being the substance as notion 
eye " or form of the eye. The eye is the matter of eyesight, 

and in default of eyesight it is no longer an eye, except equivocally,

like an eye in stone or in a picture. What has been said of the 
part must be understood to apply to the whole living body ; for, 
as the sensation of a part of the body is to that part, so is sensation 
as .a whole to the whole sentient body as such. By that which 10 
has in it the capacity of life is meant not the body which has lost 
its soul, but that which possesses it. Now the seed in animals, 
like the fruit in plants, is that which is potentially such and such 
a body. As, then, the cutting of the axe or the seeing of the eye n 
is full actuality, so, too, is the waking state ; while the soul is 
actuality in the same sense as eyesight and the capacity of the 
instrument. The body, on the other hand, is simply that which is 
potentially existent But, just as in the one case the eye means 
the pupil in conjunction with the eyesight, so in the other soul and 
body together constitute the animal. 

Now it needs no proof that the soul or if it is divisible into 12 
parts, certain of its parts cannot be separated from the 

Soul in- 

separable body, for there are cases where the actuality belongs to 
rom o y. ^ e parts themselves. There is, however, no reason why 
some parts should not be separated, if they are not the actualities 
of any body whatever. Again, it is not clear whether the soul 13 
A possible may not be the actuality of the body as the sailor is of the 
analogy. ship. This, then, may suffice for an outline or provisional 
sketch of soul. 

But, as it is from the things which are naturally obscure, though 2 
more easily recognised by us, that we proceed to what is clear 
and, in the order of thought, more knowable, we must employ 
this method in trying to give a fresh account of soul. For it is 
not enough that the defining statement should set forth 
good the fact, as most definitions do ; it should also contain 

and present the cause: whereas in practice what is stated 
in the definition is usually no more than a conclusion. For 
example, what is quadrature ? The construction of an equilateral 
rectangle equal in area to a given oblong. But such a definition 
expresses merely the conclusion. Whereas, if you say that 
quadrature is the discovery of a mean proportional, then you state 
the reason. 

We take, then, as our starting-point for discussion that it is life 2 
which distinguishes the animate from the inanimate. But the 
term life is used in various senses ; and, if life is present in but a

single one of these senses, we speak of a thing as living. Thus 
various there is intellect, sensation, motion from place to place 
Sensor 10 " an d rest > ^ e m ti n concerned with nutrition and, 
operations, further, decay and growth. Hence it is that all 3 
plants are supposed to have life. For apparently they have within 

themselves a -faculty and principle whereby they grow 
mum in and decay in opposite directions. For plants do not 

grow upwards without growing downwards ; they grow 
in both directions equally, in fact in all directions, as many as 
are constantly nourished and therefore continue to live, so long 
as they are capable of absorbing nutriment. This form of life 4 
can be separated from the others, though in mortal creatures the 
others cannot be separated from it. In the case of plants the fact 
is manifest : for they have no other faculty of soul at all. 

It is, then, in virtue of this principle that all living things live, 

whether animals or plants. But it is sensation primarily 

Sensation r r J 

in ail which constitutes the animal. For, provided they have 

sensation, even those creatures which are devoid of move- 
ment and do not change their place are called animals and are 
not merely said to be alive. Now the primary sense in all animals 5 
is touch. But, as the nutritive faculty may exist without touch 
or any form of sensation, so also touch may exist apart from the 
other senses. By nutritive faculty we mean the part of the soul 
in which even plants share. Animals, however, are found uni- 
versally to have the sense of touch : why this is so in each of the 
two cases will be stated hereafter. 

For the present it may suffice to say that the soul is the origin 6 
of the functions above enumerated and is determined by them, 
namely, by capacities of nutrition, sensation, thought, and by 
Mutual motion. But whether each one of these is a soul or part 7 
of?hese n of a soul and > if a P art > whether it is only logically 
functions. distinct or separable in space also is a question, the 
answer to which is in some cases not hard to see: other cases 
present difficulties. For, just as in the case of plants some of them 8 
are found to live when divided and separated from each other 
(which implies that the soul in each plant, though actually one, 
is potentially several souls), so, too, when insects or annelida are 
cut up, we see the same thing happen with other varieties of soul : 
I mean, each of the segments has sensation and moves from place

and pain : and, where these are, desire also must of necessity be

ever, to be a distinct species of soul, and it alone is 
capable of separation from the body, as that which is eternal from 
that which is perishable. The remaining parts of the soul are, 10 
as the foregoing consideration shows, not separable in the way 
that some allege them to be : at the same time it is clear that they 
are logically distinct. For the faculties of sensation and of opinion 
taken in the abstract are distinct, since to have sensation and to 
opine are distinct. And so it is likewise with each of the other 
faculties above mentioned. Again, while some animals possess n 
all these functions, others have only some of them, others only 
one. It is this which will differentiate animal from animal. The 
reason why this is so must be investigated hereafter. The case is 
similar with the several senses : some animals have all of them, 
others some of them, others again only one, the most indispensable, 
that is, touch. 

Now " that by which we live and have sensation " is a phrase 12 
A second with two meanings, answering to the two meanings of 
deduction that by which we k now (the latter phrase means, 
definition. firstly, knowledge and, secondly, soul, by either of which 
we say we know). Similarly that by which we have health means 
either health itself or a certain part, if not the whole, of the body. 
Now of these knowledge and health are the shape and in some 
sort form, the notion and virtual activity, of that which is capable 
of receiving in the one case knowledge, in the other health: 
that is to say, it is in that which is acted upon or conditioned 
that the activity of the causal agencies would seem to take 
effect. Now the soul is that whereby primarily we live, per- 
ceive, and have understanding: therefore it will be a species of

notion or form, not matter or substratum. Of the three meanings 13 
of substance mentioned above, form, matter and the whole made 
up of these two, matter is potentiality and form is actuality. And, 
since the whole made up of the two is endowed with soul, the body 
is not the actuality of soul, but soul the actuality of a particular 

body. Hence those are right who regard the soul as not 14 
independent of body and yet at the same time as not itself 
nortden- f ' a species of body. It is not body, but something be- 
body. with ' longing to body, and therefore resides in body and, what 
is more, in such and such a body. Our predecessors were 
wrong in endeavouring to fit the soul into a body without further 
determination of the nature and qualities of that body : although 
we do not .even find that of any two things taken at random the 
one will admit the other. And this result is what we might expect. 15 
For the actuality of each thing comes naturally to be developed 
in the potentiality of each thing : in other words, in the appropriate 
matter. From these considerations, then, it is manifest that soul is 
a certain actuality, a notion or form, of that which has the capacity 
to be endowed with soul. 

Of the powers of soul above mentioned, namely, those of 3 
The vital nutrition, appetency, sensation, locomotion and under-

the nutritive faculty only : other things along with this have 
A etenc sensation ; and, if sensation, then also appetency : where 
implied under appetency we include desire, anger and wish. But 

in touch. i u ... i j. I i. j i- 

all animals have at least one sense, touch : and, where 
sensation is found, there is pleasure and pain, and that which 
causes pleasure and pain ; and, where these are, there also is desire, 
desire being appetite for what is pleasurable. Again, they have 3 
a sensation concerned with nutriment, touch being such a sense. 
For it is by what is dry and moist, hot and cold, that all living 
things are nourished (and these qualities are perceived by touch, 
whereas the other sensibles are not, except incidentally): for sound, 
colour and odour contribute nothing to nutriment, while flavour

is one of the tangible objects. Hunger again, and thirst are forms 
of desire, the one for what is hot or dry, the other for what is cold 
or moist. Flavour is, as it were, the seasoning of these. We will 
deal with these in detail hereafter : at present let it suffice to say 
that all animals which have the sense of touch are also endowed 
with appetency. Whether they have imagination is not clear : this, 
Higher ^j must be considered later. Some have in addition 4 
functions. ^ power o f locomotion. Others that is to say, man 
and any other species like man or, possibly, superior to him have 
also the thinking faculty and intellect. 

From this it is clear that there is one definition of soul exactly 5 
A single as there is one definition of figure : for there is in the 
of soiY,as one case no fig" ure excepting triangle, quadrilateral and 
of figure. f^g rest, -nor is there in the other any species of soul 
apart from those above mentioned. Again, a definition might be 
constructed which should apply to all figures, but not specially 
to any species of figure. And similarly with the species of soul 
above enumerated. Hence it would be- absurd here as elsewhere 
to seek a general definition which will not be properly a definition 
of anything in existence and will not be applicable to the particular 
irreducible species before us, to the neglect of the definition which 
is so applicable. 

The types of soul resemble the series of figures. For, alike 6 
in figures and in things animate, the earlier form exists 

The as- 

potentially in the later, as, for instance, the triangle 



vita? potentially in the quadrilateral, and the nutritive faculty 

functions. -^ that which has sensation. So that we must examine 
in each case separately, what is the soul of plant, of man or of 
beast. Why they are related in this order of succession remains 7 
to be considered. There is no sensitive faculty apart from the 
nutritive : and yet the latter exists without the former in plants. 
Again, none of the other senses is found apart from touch ; while 
touch is found apart from the others, many animals having neither 
sight nor hearing nor sense of smell. Also of those which possess 
sensation, some can move from place to place, others " cannot

Lastly and most rarely, they have the reasoning faculty and 
thought. For those perishable creatures which possess reason are 
endowed with all the other species of soul, but not all those which 
possess each of the other faculties have reason. Indeed, some of 
them have not even imagination, while others live by imagination 
alone. As for the speculative intellect, it calls for a separate 
discussion. Meanwhile it is clear that an account of the several 
faculties is at the same time the most appropriate account of 
soul. 

The enquirer who approaches this subject must ascertain what 4 
order of each of these faculties is before he proceeds to investigate 
procedure, fa^. questions next in order and so forth. But if we are 
asked to state what each of these is ; that is to say, what the cogni- 
tive, sensitive and nutritive faculties respectively are, we must begin 
by stating what the act of thinking is and what the act of sensation 
is. For activities and functions are logically prior to faculties. 
But, if so, and if a study of the correlative objects should have 
preceded, these objects will for the same reason have to be defined 
first : I mean, nutriment and the sensible and intelligible. Con- 2 
sequently we have first to treat of nutriment and of generation. 

The nutritive soul belongs to other living things as well as 
. man, being the first and most widely distributed faculty, in virtue 

ei ^ w h* c h a ^ things possess life. Its functions are repro- 
logicai duction and assimilation of nutriment. For it is the 

aspect of t f Hi-. i - ./- f 

most natural function in all living things, if perfect 



and not defective or spontaneously generated, to repro- 
duce their species; animal producing animal and plant plant, in 
order that they may, so far as they can, share in the eternal and 
the divine. For it is that which all things yearn after, and that is 
the final cause of all their natural activity. Here final cause is an 
ambiguous term, which denotes either the purpose for which, or 
the person for whom, a thing is done. Since, then, individual 
things are incapable of sharing continuously in the eternal and 
the divine, because nothing in the world of perishables can abide 
numerically one, and the same, they partake in the eternal and

divine, each in the only way it can, some more, some less. That is 
to say, each persists, though not in itself, yet in a representative 
which is specifically, not numerically, one with it. 

Now the soul is cause and origin of the living body. But cause 3 
Digression and origin are terms used in various senses : accord- 
as three ul ^ n S^Y sou l * s cause in the three senses of the word 
fold cause. a i re ady determined. For the soul is the cause of 
animate bodies as being in itself the origin of motion, as final 
cause and as substance. Clearly it is so as substance, substance 4 
being the cause of all existence. And for living things existence 
means life, and it is the soul which is the cause and origin of life. 
Furthermore, actuality is the not fun" or' form" of that which has -- 
potential existence. Manifestly, too, the oul is final cause. For 5 
nature, like intelligence, acts for a purpose, and this purpose is 
for it an end. Such an end the soul is in animals, and this in the 
order^of nature, for all the natural bodies are instruments of soul : 
and this is as true of the bodies of plants as of those of animals, 
shewing that all are means to the soul as end ; where end has two 
senses, the purpose for which and the person for whom. Moreover, 6 
the soul is also the origin of motion from place to place, but not 
all living things have this power of locomotion. Qualitative change, 
also, and growth are due to soul. For sensation is supposed to be a 
sort of qualitative change, and nothing devoid of soul has sensation. 
The same holds of growth and decay. For nothing undergoes ' 
natural decay or growth except it be nourished, and nothing is 
nourished unless it shares in life. 

Empedocles is mistaken in adding that in plants, in so far as 7 
they strike their roots downwards, growth takes place 

Error of J , 

because the earth in them has a natural tendency in 



this direction and that, when they shoot upwards, it 
is because the fire in them has a similar tendency upwards. He 
is wrong in his view of up and down. For up and down are not the 
same for all individuals as for the universe. On the contrary, the 
roots of plants correspond to the heads of animals, if we are to

make identity and diversity of organs depend upon their functions. 
Besides, what is it that holds together the fire and the earth, 
tending, as they do, in opposite directions ? For they will be rent 
asunder, unless there is something to prevent it: while, if there 
is, it is this which is the soul and the cause of growth and nourish- 
ment. 

Some hold the nature of fire to be singly and solely the cause 8 
of nourishment and growth. For it would seem that fire 

Fire not & 

the cause is the only body or element which of itself is nourished 
growt . an ^ g rows> Hence fire might be supposed to be the 
operative cause, both in plants and animals. Whereas, though it is 
in a sense a joint cause, it is not a cause absolutely : it is rather the 
soul which is so. For fire goes on growing to infinity, as long 
as there is fuel to be consumed, but in natural wholes there is 
always a limit or proportion which determines growth and size. 
But this belongs to the soul and not to fire, to form rather than 
to matter. 

The nutritive faculty of the soul being the same as the repro- 9 
ductive, it is necessary first to give a definition 1 of nutriment. For 
it is by the nutritive function that this faculty is separated off 
from the others. The common view is that contrary is nutriment 
to contrary ; though not in every case, but wherever each 
of two contraries is not only generated by, but derives 
growth from, the other. For many things are derived from one 
another, but not all of them are quantities: thus the sick man 
becomes well. But it is found that even the contraries supposed 
to derive growth from each other are not fed by one another in the 
same way: while water serves to feed fire, fire is not nutriment 
to water. It would seem, then, that it is in the simple bodies 
above all that of two contraries one is nutriment and the other 
is nourished. Yet here is a difficulty. It is said by the one 10 
side that like is nourished by, as well as derives its growth from, 
like; while the others, again, as we explained, hold that con- 
trary is nourished by contrary, on the ground that like cannot be 
affected by like, while food undergoes change and is digested. 
Now change is always in the direction of the opposite, or of the 
intermediate state. Further, nutriment is acted upon by that 
which it nourishes,- and not the latter by the former: just as

the carpenter is not affected by his material, but on the contrary 
the material by the carpenter. The carpenter merely passes to 
activity from inaction. But it makes a difference whether by n 
nutriment we mean the final, or the primary, form of what is 
added. If both are nutriment, the one as undigested, the other as 
digested, it will be possible to use the term nutriment in conformity 
with both theories. For, in so far as it is undigested, contrary is 
nourished by contrary : and, in so far as it is digested, like by like. 
So that clearly both sides are in a manner partly right and partly 
wrong. But, since nothing is nourished unless it possesses life, 12 
that which is nourished must be the animate body as such : so that 
nutriment also is relative to the animate being which it nourishes : 
and this not incidentally merely. 

There is, however, a difference between nutritivity and con- 13 
ducivity to growth. In so far as the animate thine: is 

Growth, ...... - 

quantitative, what is taken promotes growth; in so far 
as it is a definite individual, what is taken nourishes. For the 
animate thing preserves its substance or essential nature and exists 
as long as it is nourished : and it causes the production, not of that 
which is nourished, but of another individual like it. Its essential 
nature already exists, and nothing generates itself, it only main- 
tains its existence. Hence the above described principle of the 
soul is the power to preserve in existence that which possesses it 
in so far as it is a definite individual, while nutrition prepares it 
for activity. Therefore it cannot live when deprived of nutriment. 
There are, then, these three things, that which is nourished, that 14 
with which it is nourished, and that which nourishes it. The last 
of the three is the primary soul, that which is nourished is the 
body which contains the soul, that wherewith it is nourished is 
nutriment. As, however, it is right to name all things from the 15 
end they subserve, and the end here is reproduction of the species, 
the primary soul is that which is capable of reproducing the 
species. That with which the living thing is nourished may be 16 

understood in two senses, just as that with which one 
and nutri- steers may mean the hand or the rudder ; the former, the 
ment * hand, both causing motion and being moved, the latter,

the rudder, being simply moved. Now it is necessary that all food 
should be capable of digestion, and digestion is promoted by heat ; 
this explains why every animate thing has warmth. This, then, 
is an outline of what nutriment is. It must be more clearly 
defined hereafter in the discussion devoted specially to it 

Now that these points have been determined, let us proceed 5 
sensation to * >enera ^ discussion of all sensation. As above ^\ 
remarked, sensation consists in being moved and acted j 
upon, for it is held to be a" "species of qualitative change. Some -, 
add that like is in fact acted upon by like. How far this is 
possible or impossible we have explained in the general discussion ' 
of action and passivity. The question arises why there is no 2 
sensation of the senses themselves : that is, why they produce no 
sensation apart from external sensibles, though the senses contain 
fire, earth and the other elements, which are the objects of sensation 
either in themselves or through their attributes. Evidently it 
Sensation follows that the faculty of sensible perception exists not 
tiai^^ac 1 -" * n activity, but only in potentiality. Hence it must be 
tuai. here as with the fuel which does not burn of and in 

itself without something to make it burn ; otherwise it would 
kindle itself and would have no need of the fire which is actually 
existent. Now to have sensation has two meanings: we use the 
terms hearing and ' seeing of that which has the capacity to hear 
and see, even though it be at the time asleep, just as we do of 
that which already actually hears and sees. And therefore sensa- 
tion, too, will have two meanings : it may mean either potential 
or actual sensation. Similarly with having sensation, whether 
potential or actual. 

Let us then first proceed on the assumption that to be acted 3 
Agent and upon or moved is identical with active operation. For 
patient. movement is in fact active operation of some sort, 
though incomplete, as we have elsewhere explained. But in 
every case things are acted upon and moved by an agent in 
actual operation. It follows that in one sense what is acted upon 
is acted upon by what is like it, in another sense by what is unlike 
it, as we have explained. That is to say, while being acted upon it 
is unlike, after it has been 'acted upon it is like the agenjfc.

CH. 5 417 a 21417 b 13 73 

We must also draw a distinction in regard to the terms 4 
potentiality and actuality : at present we are using them without 
TWO mean- qualification. For instance, we may use the term wise, 
p"?en f firstly, in the sense in which we might speak of man 
tiaiity as w i SCj because man is one of the genus of beings 

which are wise and have wisdom ; secondly, in the sense in 
which we at once call the man wise who has learnt, say, 
grammar. Now of these two men each possesses the capacity, but 
in a different sense: the one because the genus to which he 
belongs, that is to say, his matter, is potentially wise ; the other 
because he is capable, if he chose, of applying the wisdom he has 
acquired, provided there is nothing external to hinder. Whereas 
he who is at the moment exercising his wisdom is in actuality and 
is wise in the proper sense of the term : for example, he knows the 
A before him. Thus the first two are both potentially wise : the 
first becomes wise actually after he has undergone qualitative 
change through instruction and often after transition from the 
reverse condition ; while in the latter case it is by another kind 
of transition that the man passes from the mere possession, with- 
out the use, of sensation or grammar to the use of it 

To suffer or be acted upon, too, is a term of more than one 5 
meaning. Sometimes it means a sort of destruction by the 
and of contrary, sometimes it is rather a preservation of what 

being acted is potentially existent by what is actually existent and 
upon " like it, so far as likeness holds of potentiality when 

compared with actuality. For it is by exercise of knowledge that 
the possessor of knowledge becomes such in actuality : and this 
either is no qualitative change (for the thing develops into its own 
nature and actuality), or else is qualitative change of a different sort. 
Hence it is not right to say that that which thinks undergoes 
change when it thinks, any more than that the builder undergoes 
change when he builds. That, then, which works the change from 
potential existence to actuality in a thinking and intelligent being 
should properly receive a different name and not be called in- 
struction : while that which learns and is brought from potential to 
actual knowledge by that which is in actuality and capable of 
instructing should either not be said to suffer or be acted upon at

all, or else two modes of change should be assumed, one to the 
negative states and the other to the normal habits and the true 
nature. 

In the sensitive subject the first change is due to the 6 
parent : once generated it possesses sensation exactly in the same 
sense as we possess knowledge. And to have actual sensation 
Actual corresponds to exercise of knowledge. There is this 

cod?- tion difference, however, that in the one case the causes of 
tioned by the activity are external : as, for instance, the objects of 
temai sight, hearing and the other senses. The reason is 

sensible. ^^ actua } se nsation is always of particulars, while 
knowledge is of universals : and these universals are, in a manner, 
in the soul itself. Hence it is in our power to think whenever we 
please, but sensation is not in our power : for the presence of the 
sensible object is necessary. It is much the same with the sciences 
which deal with sensible objects ; and for the same reason, namely, 
that sensibles are particulars and are external. 

But we shall have a further opportunity of making this clear 
hereafter. For the present let us be content to have established 7 
that of the two meanings of potentiality, the one according to 
which a child might be called potentially a general, and the other 
according to which a man of full age might be so called, it is the 
latter which applies to the faculty of sense-perception. But as this 
distinction has no word to mark it, although the fact and the 
nature of the distinction have been established, we are compelled 
to use the terms to suffer or be acted upon and to be qualitatively 
changed as if they were the proper terms. Now, as has been 
explained, the sensitive faculty is potentially such as the 
sensible object is in actuality. While it is being acted 
upon, it is not yet similar, but, when once it has been 
sensation acted upon, it is assimilated and has the same character 

as the sensible object. 
In considering each separate sense we must first treat of their 6 

objects. By the sensible object may be meant any one 
bie object: of three things, two of which we say are perceived in 
themselves or directly, while the third is perceived 
f er acciden* or indirectly. Of the first two the one is 



several ^he special object of a particular sense, the other an 

object common to all the senses. By a special object of 2 
a particular sense I mean that which cannot be perceived by any 
other sense and in respect to which deception is impossible; for

example, sight is of colour, hearing of sound and taste of flavour, 
while touch no doubt has for its object several varieties. But at 
any rate each single sense judges of its proper objects and is not 
deceived as to the fact that there is a colour or a sound ; though as to 
what or where the coloured object is or what or where the object is 
which produces the sound, mistake is possible. Such then, are the 3 
special objects of the several senses. By common sensibles are 
or (a) by meant motion, rest, number, figure, size : for such 
inco^ 1 -^ 3 qualities are not the special objects of any single sense, 
mon - but are common to all. For example, a particular motion 

can be perceived by touch as well as by sight. What is meant 4 

by the indirect object of sense may be illustrated if we 
Xhichhave suppose that the white thing before you is Diares' son. 
SSesSe ^ r u P erce i ve Diares' son, but indirectly, for that which 
indirectly y OU perceive is accessory to the whiteness. Hence you 
are not affected by the indirect sensible as such. Of the 
two classes of sensibles directly perceived it is the objects special 
to the different senses which are properly perceptible : and it is 
to these that the essential character of each sense is naturally 
adapted. 

The object, then, of sight is the visible: what is visible is colour 7 
sight and and something besides which can be described, though 
colour. j t j ias no name- What we mean will best be made clear 
as we proceed. The visible, then, is colour. Now colour is that 
with which what is visible in itself is overlaid : and, when I say 
in itself, I do not mean what is visible by its essence or form, but 
what is visible because it contains within itself the cause of 
visibility, namely, colour. But colour is universally capable of 
exciting change in the actually transparent, that is, in light ; this 
being, in fact, the true nature of colour. Hence colour is not 
visible without light, but the colour of each object is always seen 
in light. And so we shall have first to explain what light is. 

There is, then, we assume, something transparent ; and by this 2 
The I mean that which, though visible, is not properly 

medium. speaking, visible in itself, but by reason of extrinsic 
colour. Air, water and many solid bodies answer to this de- 
scription. For they are not transparent quA air or qu& water,

but because there is a certain natural attribute present in both 
of them which is present also in the eternal body on high. Light 
is the actuality of this transparent qud transparent But where 
the transparent is only potentially present, there darkness is 
actually. Light is a sort of colour in the transparent when 
made transparent in actuality by the agency of fire or something 
resembling the celestial body : for this body also has an attribute 
which is one and the same with that of fire. What the transparent 
Light not is, and what light is, has now been stated ; namely, that 
corporeal. ft j g ne jth er fire nor body generally nor an effluence from 
any body (for even then it would still be a sort of body), but the 
presence of fire or something fiery in the transparent. For it 
is impossible for two bodies to occupy the same space at the 
same time. 

Light is held to be contrary to darkness. But darkness 3 
is absence from the transparent of the quality above described : 
so that plainly light is the presence of it. Thus Empedocles and 
others who propounded the same view are wrong when 

The velo- ,. i - , . . 

city of light they represent light as moving in space and arriving 
mere i a t a given point of time between the earth and that 

which surrounds it without our perceiving its motion. For this 
contradicts not only the clear evidence of reason, but also the facts 
of observation : since, though a movement of light might elude 
observation within a short distance, that it should do so all the 
way from east to west is too much to assume. 

It is that which is colourless which is receptive of colour, as 4 
it is that which is soundless which is receptive of sound. And 
the transparent is colourless, and so is the invisible or the dimly 
visible which is our idea of the dark. Such is the transparent 
medium, not indeed when it is in actuality, but when potentially 
transparent. For it is the same natural attribute which is at one 
time darkness and at another time light. It is not everything 
visible which is visible in light, but only the proper colour of each 
thing. Some things, indeed, are not seen in daylight, though they 
produce sensation in the dark : as, for example, the 

Phosphor- , - -. . r -i - i 

escent things of fiery and glittering appearance, for which 

objects. there is no one distinguishing name, like fungus, horn,

the heads, scales and eyes of fishes. But in no one of these cases 
is the proper colour seen. Why these objects are seen must 
be discussed elsewhere. At present this much is clear, that the 5 
object seen in light is colour, and this is why it is not seen without 
light For the very quiddity of colour is, as we saw, just this, that 
it is capable of exciting change in the operantly transparent 
medium: and the activity of the transparent is light. There is clear 
evidence of this. If you lay the coloured object upon your eye, you 
will not see it. On the contrary, what the colour excites is the 
transparent medium, say, the air, and by this, which is continuous, 
the sense-organ is stimulated. For it was a mistake in Democritus 6 
Necessit to su PP ose ^at if the intervening space became a void, 
of a even an ant would be distinctly seen, supposing there 

me mm. were one j n the sky. That is impossible. For sight takes 
place through an affection of the sensitive faculty. Now it cannot 
be affected by that which is seen, the colour itself: therefore it 
can only be by the intervening medium : hence the existence of 
some medium is necessary. But, if the intermediate space became 
a void, so far from being seen distinctly, an object would not be 
visible at all. 

We have explained the reason why colour must be seen in 7 
light. Fire is visible both in light and in darkness : and necessarily 
so, for it is owing to fire that the transparent becomes transparent. 
The same argument holds for sound and odour. For no sound 8 
or scent produces sensation by contact with the sense-organ : it 
is the intervening medium which is excited by sound and odour 
and the respective sense-organs by the medium. But, when the 
body which emits the sound or odour is placed on the sense-organ 
itself, it will not produce any sensation. The same holds of touch 
and taste, although it appears to be otherwise. The reason for this 
will be seen hereafter. The medium for sounds is air, that for odour 9 
has no name. For there is assuredly a common quality in air 
and water, and this quality, which is present in both, stands to 
the body which emits odour in the same relation as the transparent

to colour. For the animals that live in water also appear to have 
the sense of smell. But man and the other land-animals which 
breathe are unable to smell without inhaling breath. The reason 
for this, too, must be reserved for future explanation. 

Let us now begin by determining the nature of sound and 8 
sound and hearing. There are two sorts of sound, one a sound 
hearing. which is operant, the other potential sound. For some 
things we say have no sound, as sponge, wool ; others, for ex- 
ample, bronze and all things solid and smooth, we say have sound, 
because they can emit sound, that is, they can produce actual 
sound between the sonorous body and the organ of hearing. When 2 
actual sound occurs it is always of something on something and 
in something, for it is a blow which produces it. Hence it is 
impossible that a sound should be produced by a single thing, 
for, as that which strikes is distinct from that which is struck, that 
which sounds sounds upon something. And a blow implies spatial 
motion. As we stated above, it is not concussion of any two 
things taken at random which constitutes sound. Wool, when 
struck, emits no sound at all, but bronze does, and so do all smooth 
and hollow things ; bronze emits sound because it is smooth, while 
hollow things by reverberation produce a series of concussions after 
the first, that which is set in motion being unable to escape. 
The Further, sound is heard in air and, though more faintly, 

medium. j n wa ter. It is not the air or the water, however, which 3 
chiefly determine the production of sound : on the contrary, there 
must be solid bodies colliding with one another and with the air : 
and this happens when the air after being struck resists the impact 
and is not dispersed* Hence the air must be struck quickly and 
forcibly if it is to give forth sound ; for the movement of the striker 
must be too rapid to allow the air time to disperse: just as would 
be necessary if one aimed a blow at a heap of sand or a sandwhirl, 
while it was in rapid motion onwards. 

Echo is produced when the air is made to rebound backwards 4 
like a ball from some other air which has become a single 
mass owing to its being within a cavity which confines

it and prevents its dispersion. It seems likely that echo is always 
produced, but is not always distinctly audible : since surely the 
same thing happens with sound as with light. For light is always 
being reflected ; else light would not be everywhere, but outside the 
spot where the sun's rays fall there would be darkness. But it 
is not always reflected in the same way as it is from water or 
bronze or any other smooth surface ; I mean, it does not always 
produce the shadow, by which we define light. 

Void is rightly stated to be the indispensable condition of 5 
conditions hearing. For the air is commonly believed to be a void, 
ance S and an< * ^ * s t ^ ie a * r which causes hearing, when being one 
hearing. anc j continuous it is set in motion. But, owing to its 
tendency to disperse, it gives out no sound unless that which is 
struck is smooth. In that case the air when struck is simultaneously 
reunited because of the unity of the surface; for a smooth body 
presents a single surface. 

That, then, is resonant which is capable of exciting motion in 6 
a mass of air continuously one as far as the ear. There is air 
naturally attached to the ear. And because the ear is in air, when 
the external air is set in motion, the air within the ear moves. 
Hence it is not at every point that the animal hears, nor that the 
air passes through : for it is not at every point that the part which 
is to set itself in motion and to be animate has a supply of air. Of 
itself, then, the air is a soundless thing because it is easily broken 
up. But, whenever it is prevented from breaking up, its movement 
is sound. But the air within the ears has been lodged fast within 
walls to make it immoveable, in order that it may perceive exactly 
all the varieties of auditory movement. This is why we hear in 
water also, because the water does not pass right up to the air 
attached to the ear, nor even into the ear at all, because of its 
convolutions. Should this happen, hearing is destroyed, as it is 
by an injury to the membrane of the tympanum, and as sight is by 
an injury to the cornea. Further, we have evidence whether we 
hear or not, according as there is or is not always a ringing sound in

the ears, as in a horn : for the air imprisoned there is always moving 
with a proper motion of its own. But sound is something of external 
origin and is not native to the ear. And this is why it is said that 
we hear by means of what is empty and resonant, because that by 
which we hear has air confined within it. 

Does that which is struck emit the sound or that which strikes ? 7 
Is it not rather both, but each in a different way ? For sound is 
motion of that which is capable of being moved in the same 
manner as things rebound from smooth surfaces when struck 
sharply against them. Thus, as above remarked, it is not everything 
which, when struck or striking, emits sound : supposing, for instance, 
a pin were to strike against a pin, there would be no sound. The 
thing struck must be of even surface, so that the air may rebound 
and vibrate in one mass. 

The varieties of resonant bodies are clearly distinguished by the 8 
sound they actually emit. For, as without light colours are not seen, 
so without sound we cannot distinguish high and low 
or acute and grave in pitch. These latter terms are used 
by analogy from tangible objects. For the acute, that is, the high, 
note moves the sense much in a little time, while the grave or low 
note moves it little in much time. Not that what is shrill is 
identically rapid, nor what is low is slow, but it is in the one 
case the rapidity, in the other the slowness, which makes the 
motion or sensation such as has been described. And it would 
seem that there is a certain analogy between the acute and 
grave to the ear and the acute and blunt to the touch. For 
that which is acute or pointed, as it were, stabs, while the blunt, 
as it were, thrusts, because the one excites motion in a short, the 
other in a long time, so that per accidens the one is quick, the other 
slow. Let this account of sound suffice. 

Voice is a sound made by an animate being. No inanimate 9 

thing is vocal, though it may by analogy be said to be 

vocal, as in the case of the pipe, the lyre and all other 

inanimate things that have pitch and tune and articulation : for these 

qualities, it would seem, the voice also possesses. But many animals 

have no voice: that is to say, all bloodless animals and, among 

animals that have blood, fishes. And this is what we might 

expect, since sound is a movement of air. Those fishes which

are said to possess voice, such as those in the Achelous, merely 
make a noise with their gills or some other such part. Voice is 10 
sound made by an animal, and not by any part of its body in- 
differently. But, as in every case of sound there is something 
that strikes, something struck and a medium, which is air, it is 
reasonable that only creatures which inhale air should have voice. 
For here nature uses the air that is inhaled for two purposes, just 
as it uses the tongue for tasting and for speech, the former use, for 
tasting, being indispensable and therefore more widely found, while 
expression of thought is a means to well-being. Similarly nature uses 
the breath first as a necessary means to the maintenance of internal 
warmth (the reason for which shall be explained elsewhere) and, 
further, as a means of producing voice and so promoting well-being. 
The organ of respiration is the larynx, and the part to which this n 
part is subservient is the lung : for it is this organ, namely, the 
lung, which enables land animals to maintain a higher temperature 
than others. Respiration is also needed primarily for the region about 
the heart. Hence, as we draw breath, the air enters : and so the 
impact upon the windpipe, as it is called, of the air breathed is 
voice, the cause of the impact being the soul which animates the 
vocal organs. For, as we said before, it is not every sound made 
by an animal that is voice. Noise can be produced even with the 
tongue or as in coughing: but it is necessary for voice that the 
part which strikes should be animate and that some mental image 
should be present. For voice is certainly a sound which has signifi- 
cance and is not like a cough, the noise of air respired : rather with 
this air the animal makes the air in the windpipe strike against the 
windpipe. A proof of this is the fact that we cannot speak while 12 
inhaling or exhaling breath, but only while we hold it in : for 
anyone who holds his breath uses the breath so held to cause 
motion. And it is evident why fishes are voiceless. It is because 
they have no larynx. And they are without this part because 
they do not take in the air nor breathe. Why this is so does 
not concern us here.

CH. 9 421 a 7 421 b 4 91 

Of smell and the object of smell it is less easy to speak de- 9 
finitely than of the senses above-mentioned : for the nature of 
odour is by no means so clear as is the nature of sound or of 
colour. The reason is that this sense in us is not exact, but 
_ . inferior to that of many animals. In fact, man has 

Smell in J ' 

man de- a poor olfactory sense and perceives none of the objects 

fective. J \ - ... 

of smell unless they be painful or pleasant, which im- 
plies that the organ is wanting in accuracy. It is reasonable to 2 
suppose that animals with hard eyes perceive colour in the same 
vague way and do not distinguish the varieties of colour except in 
so far as they do, or do not, inspire fear. And this is the way in 
which mankind perceive odours. For it would seem that, while 
there is an analogy to taste and the varieties of flavour answer 
to the varieties of smell, our sense of taste is more exact because 
it is a modification of touch and the sense of touch is the most exact 
of man's senses. In the other senses man is inferior to many of 
the animals, but in delicacy of touch he is far superior to the rest 
And to this he owes his superior intelligence. This may be seen 
from the fact -that it is this organ of sense and nothing else which 
makes all the difference in the human race between the natural 
endowments of man and man. For hard-skinned men are dull of 
intellect, while those who are soft-skinned are gifted. 

As with flavours, so with odours : some are sweet, some bitter. 3 
(But in some objects smell and* flavour correspond ; for example, 
varieties they have sweet odour and sweet flavour : in other 
of odour things the opposite is the case.) Similarly, too, an odour 
flavour. may be pungent, irritant, acid or oily. But because, as 
we said above, odours are not as clearly defined as the corre- 
sponding flavours, it is from these latter that the odours have 
taken their names, in virtue of the resemblance in the things. 
Thus the odour of saffron and honey is sweet, while the odour 
of thyme and the like is pungent ; and so in all the other cases. 
Again, smell corresponds to hearing and to each of the other 4 
senses in that, as hearing is of the audible and inaudible, and

sight of the visible and invisible, so smell is of the odorous and 
inodorous. By inodorous may be meant either that which is wholly 
incapable of having odour or that which has a slight or faint odour. 
The term tasteless involves a similar ambiguity. 

Further, smell also operates through a medium, namely, air or 5 
The water. For water animals, too, whether they are, or 

medium. are not ^ p OSseS sed of blood, seem to perceive odour 
as much as the creatures in the air: since some of them also 
come from a great distance to seek their food, guided by the 
scent. 

Hence there is an obvious difficulty, if the process of smell is 6 
inhalation everywhere the same, and yet man smells when in- 
a neces- haling but does not smell when instead of inhaling he 

sary con- & 

dition in is exhaling or holding his breath, no matter whether 
man * the object be distant or near, or even if it be placed 

on the inside of the nostril. The inability to perceive what 
is placed immediately on the sense-organ man shares with all 
animals : what is peculiar to him is that he cannot smell without 
inhaling. This is made plain by experiment. Consequently blood- 
less animals, since they do not breathe, might be thought to have 
a distinct sense other than those commonly recognised. But, we 
reply, that is impossible, since it is odour which they perceive. 
For perception of odour, be it fragrant or noisome, constitutes 
smelling. Moreover, it is found that these bloodless animals are 
destroyed by the same powerful odours as man, such as asphalt, 
brimstone and the like. It follows then that they do smell, but 
not by inhaling breath. 

It would seem, again, that in man the organ of this sense 7 

differs from that of the other animals, as his eyes differ from those 

of hard-eyed animals. Man's eyes have, in the eyelids, 

a sort of screen or sheath and without moving or open- 

ing them he cannot see : while the hard-eyed animals have nothing 

of the kind, but at once see whatever is taking place in the trans- 

parent medium. So, too, it seems, the organ of smell in some 

animals is unenclosed, just as is the eye, but in those which take 

in the air it has a curtain, which is removed in the process of 

inhaling, by dilatation of the veins and passages. And this is the 8

reason why animals which breathe cannot smell in the water. For 
it is necessary for them to take in breath before smelling and 
this they cannot do in the water. Odour is included under that 
which is dry, as flavour under that which is moist, and the organ of 
smell is potentially dry also. 

The object of taste is a species of tangible. And this is the 10 
reason why it is not perceived through a foreign body 
as medium : for touch employs no such medium either. 
The body, too, in which the flavour resides, the proper object of 
taste, has the moist, which is something tangible, for its 
external matter or vehicle. Hence, even if we lived in water, 
me mm. ^^ should still perceive anything sweet thrown into the 
water, but our perception would not have come through the 2 
medium, but by the admixture of sweetness with the fluid, as is 
the case with what we drink. But it is not in this way, namely, by 
admixture, that colour is perceived, nor yet by emanations. 
Nothing, then, corresponds to the medium ; but to colour, which is 
the object of sight, corresponds the flavour, which is the object of 
taste. But nothing produces perception of flavour in the 
absence of moisture, but either actually or potentially the 



producing cause must have liquid in it : salt, for instance, 
for that is easily dissolved and acts as a dissolvent upon the tongue. 

Again, sight is of the invisible as well as the visible (for dark- 3 
ness is invisible and this, too, sight discerns as well as light) and, 
further, of that which is exceedingly bright, which is likewise in- 
visible, though in a different way from darkness. Similarly hearing 
has to do with noise and silence, the former being audible, the latter 
inaudible, and, further, with loud noise, to which it is related as 
vision is to brightness, a loud and a violent sound being in a manner 
just as inaudible as a faint sound. The term invisible, be it noted, 
is applied not only to that which it is wholly impossible to see, 
which corresponds to other cases of the impossible, but also when 
a thing has imperfectly or not at all its natural properties, answer- 
ing to the footless and the kernel- less. So, too, taste has for object 
The object nat only that which can be tasted, but also the tasteless, 
of taste. ky w hich we mean that which has little flavour or hardly 
any at all, or a flavour destructive of the taste. Now in flavour 
this distinction is supposed to start with the drinkable and the

The of taste. But, since the object of taste is moist, the 

organ. sense-organ which perceives it must be neither actually 

moist nor yet incapable of becoming moist. For taste is acted 
upon by the object of taste as such. The organ of taste, then, 
which needs to be moistened, must have the capacity of absorbing 
moisture without being dissolved, while at the same time it must 
not be actually moist. A proof of this is the fact that the tongue 
has no perception either when very dry or very moist. In the, latter 
case the contact is with the moisture originally in the tongue, just 
as when a man first makes trial of a strong flavour and then tastes 
some other flavour ; or as with the sick, to whom all things appear 
bitter because they perceive them with their tongue full of bitter 
moisture. 

As with the colours, so with the species of flavour, there are, 5 
species of firstly, simple flavours, which are opposites, the sweet and 
flavour. t j ie bitter ; next to these on one side the succulent, on 
the other the salt ; and, thirdly, intermediate between these, the 
pungent, the rough, the astringent and the acid. These seem to 
be practically all the varieties of flavour. Consequently, while the 
faculty of taste has potentially the qualities just described, the 
object of taste converts the potentiality into actuality. 

The same account is to be given of touch and the tangible. 11 
If touch is not a single sense but includes more senses 
than one, there must be a plurality of tangible objects 
also. It is a question whether touch is several senses or only 
is it a one ' What, moreover, is the sense-organ for the faculty 

single of touch ? Is it the flesh or what is analogous to this 

in creatures that have not flesh? Or is flesh, on 
the contrary, the medium, while the primary sense-organ is 
something different, something internal ? We may argue thus : 2 
every sense seems to deal with a single pair of opposites, sight 
with white and black, hearing with high and low pitch, taste with 
bitter and sweet; but under the tangible are included several 
pairs of opposites, hot and cold, dry and moist, hard and soft and 
the like. A partial solution of this difficulty lies in the con-

sideration that the other senses also apprehend more than one pair 
of opposites. Thus in vocal sound there is not only high and low 
pitch, but also loudness and faintness, smoothness and roughness, 
and so on. In regard to colour also there are other similar varieties. 
But what the one thing is which is subordinated to touch as sound 
is to hearing is not clear. 

But is the organ of sense internal or is the flesh the immediate 3 

organ? No inference can be drawn, seemingly, from 
is the the fact that the sensation occurs simultaneously with 

contact. For even under present conditions, if a sort of 
membrane were constructed and stretched over the flesh, this would 
immediately on contact transmit the sensation as before. And yet 
it is clear that the organ of sense is not in this membrane ; although, 4 
if by growth it became united to the flesh, the sensation would be 
transmitted even more quickly. Hence it appears that the part 
of the body in question, that is, the flesh, is related to us as the 
air would be if it were united to us all round by natural growth. 
We should then have thought we were perceiving sound, colour 
and smell by one and the same instrument: in fact, sight, 
hearing and smell would have seemed to us in a manner to con- 
stitute a single sense. But as it is, owing to the media, by which 
the various motions are transmitted, being separated from us, the 
difference of the organs of these three senses is manifest. But in 
regard to touch this point is at present obscure. 

In fact, the animate body cannot consist of air or water 
singly, it must be something solid. The only alternative is that 
it should be a compound of earth and of these elements, as flesh 
and what is analogous to flesh profess to be. Consequently the 
body must be the naturally cohering medium for the faculty 
of touch, through which the plurality of sensations is communi- 
cated. That they are a plurality is made clear by touch in the 5 
case of the tongue, for the tongue perceives all tangible objects, 
and that at the same part at which it perceives flavour. Now, if 
the rest of the flesh also had perception of flavour, taste and touch 
would have seemed to be one and the same sense: whereas they 
are really two, because their organs are not interchangeable.

Here a question arises. All body has depth, this being the 6 
third dimension, and, if between two bodies a third body is inter- 
posed, the two cannot touch one another. Now that 

Contact * 

in water which is fluid is not independent of body, nor is that 
which is wet : if it is not itself water, it must contain 
water. But when bodies touch one another in the water, since their 
exterior surfaces are not dry, there must be water between them, 
the water with which their extremities are flooded. If, then, all 
this be true, no one thing can possibly touch another in the water, 
nor yet in the air: for the air stands to the objects in the air 
as water to the things in water, but this fact we are more apt 
to overlook, just as aquatic animals fail to notice that the things 
which touch one another in the water have wet surfaces. The 7 
question then arises : is the mode of perception uniform for all 
objects or does it differ for different objects? According to the 
prevalent view, taste and touch operate by direct contact, while 
The the other senses operate at a distance. But this view is 

medium. incorrect. On the contrary, we perceive the hard and the 
soft also mediately, just as much as we do the resonant, the visible, 
the odorous. But the latter are perceived at a distance, the former 
close at hand : and this is why the fact escapes us, since we really 
perceive all objects through a medium, though in touch and taste 
we fail to notice this. And yet, as we mentioned above, even if we 
perceived all objects of touch through a membrane without being 
aware of its interference, we should be just in the same position 
as we are now with regard to objects in the water or in the air : 
for, as it is, we suppose that we are touching the objects them- 
selves and that there is no intervening medium. But there is 8 
this difference between the tangible on the one hand and visible 
and resonant things on the other: the latter we perceive because 
the medium acts in a certain way upon us, while tangible objects 
we perceive not by any action upon us of the medium, but con- 
currently with it, like the man who is struck through his shield. 
It is not that the shield was first struck and then passed on the 
blow, but, as it happened, both were struck simultaneously. And, 9 
generally, it would seem that the flesh and the tongue are related

to the true sense-organ as are air and water to the organs of sight, 
hearing and smell respectively. But neither in the one case nor in 
the other would sensation follow on contact with the sense-organ ; 
for instance, if a body that is white were placed on the outer 
surface of the eye: which shows that the instrument that appre- 
hends the tangible is within. We should then get the same result 
as in the case of the other senses. What is placed on the sense- 
organ we do not perceive : what is placed on the flesh we do 
perceive: therefore flesh is the medium for the faculty of touch. 

It is, then, the distinctive qualities of body as body which are 10 
the objects of touch : I mean those qualities which determine the 
Tangible elements, hot or cold, dry or moist, of which we have 
qualities. previously given an account in our discussion of the 
elements. And their sense-organ, the tactile organ, that is, in n 
which the sense called touch primarily resides, is the part which has 
potentially the qualities of the tangible object. For perceiving is 
a sort of suffering or being acted upon : so that when the object 
makes the organ in actuality like itself it does so because that organ 
is potentially like it. Hence it is that we do not perceive what 

Sense * S J USt aS ^ Ot Or CO ^' ^ard Ot SO ^ aS W6 are > ^ Ut n ^ 

a mean. t k e excesses of these qualities : which implies that the 
sense is a kind of mean between the opposite extremes in the 
sensibles. This is why it passes judgment on the things of sense. 
For the mean is capable of judging, becoming to each extreme 
in turn its opposite. And, as that which is to perceive white and 
black must not be actually either, though potentially both, and 
similarly for the other senses also, so in the case of touch the 
organ must be neither hot nor cold. Further, sight is in a manner, 12 
The in- as we saw f ^ ie invisible as well as the visible, and 
tangible, j n ^ same wa y the remaining senses deal with oppo- 
sites. So, too, touch is of the tangible and the intangible : where 
by intangible is meant, first, that which has the distinguishing 
quality of things tangible in quite a faint degree, as is the case 
with the air ; and, secondly, tangibles which are in excess, such as 
those which are positively destructive. Each of the senses, then, 
has now been described in outline.

In regard to all sense generally we must understand that sense 12 
what * s ^ at w ^ich is receptive of sensible forms apart from 

- their matter > as wax re ceives the imprint of the signet- 

seal ring apart from the iron or gold of which it is made : it 
upon wax. fakes the imprint which is of gold or bronze, but not qu& 
gold or bronze. And similarly sense as relative to each sensible is 
acted upon by that which possesses colour, flavour or sound, not in 
so far as each of those sensibles is called a particular thing, but 
in so far as it possesses a particular quality and in respect of its 
Faculty character or form. The primary sense-organ is that in 2 
and organ. w hich such a power resides, the power to receive sensible 
forms. Thus the organ is one and the same with the power, but 
logically distinct from it. For that which perceives must be an 
extended magnitude. Sensitivity, however, is not an extended 
magnitude, nor is the sense : they are rather a certain character or 
power of the organ. From this it is evident why excesses in the 3 
sensible objects destroy the sense-organs. For if the motion is too 
violent for the sense-organ, the character or form (and this, as we 
saw, constitutes the sense) is annulled, just as the harmony and the 
pitch of the lyre suffer by too violent jangling of the strings. It is 4 
why evident, again, why plants have no sensation, although 

hav'eTno they have one part of soul and are in some degree af- 
sensation. fected by the things themselves which are tangible : for 
example, they become cold and hot. The reason is that they have 
in them no mean, no principle capable of receiving the forms of 
sensible objects without their matter, but on the contrary, when 
they are acted upon, the matter acts upon them as well. It might 5 

be asked whether what is unable to smell would be in any 
sensible way acted upon by an odour, or that which is incapable 
things f seeing by a colour, and so for the other sensibles. But, 

without if the object of smell is odour, the effect it produces, if it 

sensation ? J r 

produces an effect at all, is smelling. Therefore none 
of the things that are unable to smell can be acted upon by odour, 
and the same is true of the other senses : nor can things be acted 
upon when they have the power of sensation, except as they 
individually possess the particular sense required. This may also 
be shown as follows. Light and darkness do not act upon bodies 
at all ; neither does sound nor odour : it is the things which possess 
them that act. Thus it is the air accompanying the thunderbolt 
which rives the timber. But, it may be said, things tangible and 6

flavours do so act : else by what agency are inanimate things acted 
upon or changed ? Shall we, then, conclude that the objects of the 
other senses likewise act directly? Is it not rather the case that 
not all body can be affected by smell and sound, and that the 
bodies which are so affected are indeterminate and shifting; for 
example, air? For odour in the air implies that the air has been 
acted upon in some way. What then is smelling, besides a sort of 
suffering or being acted upon? Or shall we say that the act of 
smelling implies sense-perception, whereas the air, after it has been 
acted upon, so far from perceiving, at once becomes itself per- 
ceptible to sense?

That there is no other sense distinct from the five, by which 1 
NO sixth I mean sight, hearing, smell, taste, touch, anyone may 
sense. convince himself on the following grounds. Let us 

assume that, as a matter of fact, we have sensation of every 
sensible object for which touch is the appropriate sense, all qualities 
of the tangible, as such, being perceptible to us through touch. 
Let us further assume that, when any sense is lacking to us, an 
organ of sense must also be lacking ; and further, that whatever 
we perceive by actual contact is perceptible by touch, a sense 
which we do possess, while whatever we perceive mediately and 
not by actual contact is perceptible by means of the elements, 
namely, air and water. And here are implied two cases. Suppose, 2 
first, we have perception by one and the same medium of two several 
things, different in kind from one another, then whoever possesses 
the appropriate sense-organ must be percipient of both : as, for 
example, if the sense-organ consists of air and air is also 
the medium of both sound and colour. Next suppose several 
media to transmit the same object, as both air and water 
transmit colour, both being transparent, then he who possesses 
one of these alone will perceive whatever is perceptible through 
both media. Now, of the elements, air and water are the only 3 
two of which sense-organs are composed. For the pupil of the 
eye is of water, and the ear is of air, and the organ of smell 
is of one or the other, while fire, if present anywhere, enters into 
all, since nothing can be sentient without warmth. Earth, again, 
belongs to none of the sense-organs, or, at most, is a constituent 
peculiar to touch. It follows, then, that outside water and air there 
is no sense-organ. Now sense-organs composed of air and water 4

certain animals do, in fact, possess. We may infer, then, that all the 
senses are possessed by those animals which are fully developed 
and are not crippled : even the mole is found to have eyes 
beneath its skin. And thus, unless there exists some unknown 
body or some property different from any possessed by any of the 
bodies within our experience, there can be no sixth sense which 
we lack. 

Nor, again, can there be any special sense-organ for the common 5 
common sensibles, which we perceive incidentally by every sense ; 
sensibles. ^ or example, motion, rest, figure, magnitude, number, 
unity. For all of these we perceive by motion. Thus it is by 
motion that we perceive magnitude, and consequently figure, figure 
being one variety of magnitude ; while that which is at rest we 
perceive by the fact that it is not moved. Number we perceive 
by the negation of continuity and by the special sense-organs 
also : for each sensation has a single object. Clearly, then, it is 
impossible that there should be a special sense for any one of these ; 
for example, motion : for in that case we should perceive them in 
the same way as we now perceive sweetness by sight (and this we 6 
do because we have a sense which perceives both, and by this 
we actually apprehend the two simultaneously when they occur 
in conjunction). Otherwise we should never have more than an 
incidental perception of them ; as of Cleon's son we perceive not 
that he is Cleon's son, but that he is a white object, and the fact 
of his being Cleon's son is accessory to the whiteness. But of the 7 
common sensibles we have already a common perception, which 
is direct and not indirect, so that there cannot be a special sense 
for them. For, if there were, we should never perceive them other- 
wise than in the way in which we said we saw Cleon's son.

But the various senses incidentally perceive each other's 

Perception proper objects, not as so many separate senses, but as 

dens a of " forming a single sense, when there is concurrent per- 

speciai ception relating to the same object ; as, for instance, 

sensibles. 

unity of when we perceive that gall is bitter and yellow. For 
sense. ft j s certainly not the part of any other sense to declare 

that both objects are one and the same. Hence you are sometimes 
deceived and, on observing something yellow, fancy it to be gall. 

But, it might be asked, why have we several senses, instead of 8 
why have only one? I answer, it is in order that we may not be so 
^nsT^ re Hkely to overlook the common attributes, such as motion, 
than one? magnitude, number, which accompany the special sen- 
sibles. For, if sight had been our only sense and whiteness its 
object, we should have been more apt to overlook the common 
sensibles and to confuse all sensibles, because colour and magnitude, 
for instance, must always go together. As it is, the fact that the 
common attributes are found in the object of another sense also 
shows that they are severally distinct. 

Inasmuch as we perceive that we see and hear, it must either 2 
Perception be by sight or by some other sense that the percipient per- 
p^reei^e is ceives that he sees. But, it may be urged, the same sense 
by sense. w hich perceives sight will also perceive the colour which 
is the object of sight. So that either there will be two senses to 
perceive the same thing or the one sense, sight, will perceive itself. 
Further, if the sense perceiving sight were really a distinct sense, 
either the series would go on to infinity or some one of the series 
of senses would perceive itself. Therefore it will be better to 
admit this of the first in the series* Here, however, there is a 2 
uiffi. difficulty. Assuming that to perceive by sight is to see 

cuities. anc j jj^j. t j s co i our or that which possesses colour which 

is seen, it may be argued that, if you are to see that which sees, that 
which in the first instance sees, the primary visual organ, will 
actually have colour. Clearly, then, to perceive by sight does not 3 
always mean one and the same thing. For, even when we dp not 
see, it is nevertheless by sight that we discern both darkness and 
light, though not in the same manner. Further, that which sees 
is in a manner coloured. For the sense-organ is in every case

receptive of the sensible object without its matter. And this is 
why the sensations and images remain in the sense-organs even 
when the sensible objects are withdrawn. 

Now the actuality of the sensible object is one and the same 4 
_ with that of the sense, though, taken in the abstract, 

Identity of i i 

sense and sensible object and sense are not the same. I mean, for 
in%he je act example, actual sound and actual hearing are the same : 



f r ft is possible to have hearing and yet not hear; again, 
that which is resonant is not always sounding. But 
when that which is capable of hearing operantly hears and that 
which is capable of sounding sounds, the actual hearing and the 
actual sound occur simultaneously, and we might, if we pleased, call 
them audition and resonance respectively. If, then, motion, action 5 
and passivity reside in that which is acted upon, then of necessity it 
is in the potentiality of hearing that there is actual sound and there 
is actual hearing. For the activity of agent and movent comes 
into play in the patient ; and this is why that which causes motion 
need not itself be moved. The actuality of the resonant, then, is 
sound or resonance, and the actuality of that which can hear is 
hearing or audition, hearing and sound both having two meanings. 
The same account may be given of the other senses and their objects. 6 
For, just as acting and being acted upon are in the subject acted 
upon and not in the agent, so also the actuality of the sensible 
object and that of the sensitive faculty will be in the percipient 
subject. But in some cases both activities have a name ; for 
example, resonance and audition : in other cases one or the other 
has no name. Thus, while the actuality of sight is called seeing, 
that of colour has no name ; and, while the actuality of the taste- 
faculty is called tasting, that of the flavour has no name. Now, 7 
as the actuality of the object and that of the faculty of sense are one 
and the same, although taken in the abstract they are different, 
hearing and sound thus understood as operant must simultaneously 
cease to be or simultaneously continue in being, and so also with 
flavour and taste, and similarly with the other senses and their 
objects : but when they are understood as potentialities, there is no

such necessity. On this point the earlier natural philosophers were 8 
Mistake in error > when they supposed that without seeing there was 
of^eariier neither white nor black, and without tasting no flavour. 

Their statement is in one sense true, in another false. 
For the terms sensation and sensible thing are ambiguous. When 
they mean the actual sensation and the actual sensible thing, the 
statement holds good : when they mean potential sensation and 
potential sensible, this is not the case. But our predecessors 
used terms without distinguishing their various meanings. 

If, then, concord consists in a species of vocal sound, and if vocal 9 
sound and hearing are in one aspect one and the same, {though in 
another aspect not t/ie same], and if concord is a proportion, it 
follows that hearing must also be a species of proportion. And 

this is the reason why hearing is destroyed by either 
hearing, so excess, whether of high pitch or of low. And similarly, 
th^s^le in the case of flavours, excess destroys the taste, and in 
porti5n~ colours excessive brightness or darkness destroys the 

sight, and so with smell, whether the excessive odour be 
agreeable or pungent. All this implies that the sense is a proportion. < 
Hence sensibles are, it is true, pleasurable when they are brought 
into the range of this proportion pure and unmixed ; for example, 
the shrill, the sweet, the salt : in that case, I say, they are pleasur- 
able. But, speaking generally, that in which ingredients are blended 
is pleasurable in a higher degree, accord more pleasurable to the 
ear than high pitch or low pitch alone, and to touch that which 
admits of being still further heated or cooled. The due proportion 
constitutes the sense, while objects in excess give pain or cause 
destruction. 

Now each sense is concerned with its own sensible object, being 10 
resident in the organ, qua sense-organ, and judges the specific 
differences of its own sensible object. Thus sight pronounces upon 
white and black, taste upon sweet and bitter, and so with the rest.

But, since we compare white and sweet and each of the sensibles 
with each, what in fact is it by means of which we 
perceive the difference between them ? It must be by 
sense, for they are sensibles. And thus it is clear that n 
the flesh is not the ultimate organ of sense ; for, if it were, it would 
be necessary that that which judges should judge by contact with 
the sensible object Nor indeed can we with separate organs judge 
that sweet is different from white, but both objects must be clearly 
presented to some single faculty. For, if we could, then the mere 
fact of my perceiving one thing and your perceiving another would 
make it clear that the two things were different. But the single 
faculty is required to pronounce them different, for sweet and white 
are pronounced to be different. It is one and the same faculty, then, 
which so pronounces. Hence, as it pronounces, so it also thinks 12 
and perceives. Clearly, then, it is not possible with separate organs 
to pronounce judgment upon things which are separate: nor yet 
at separate times, as the following considerations show. For, 
as it is one single faculty which pronounces that good and bad 
are different, so when it judges "A is different from B" it also 
judges "B is different from A" (and in this case the "when" is 
not accidental ; I mean, accidental in the sense in which I may 
now say " Such and such things are different" without saying that 
they are different now. On the contrary, it pronounces now and 
pronounces that A and B are different now). That which judges 
judges, then, instantaneously and hence as an inseparable unit in an 
inseparable time. But, again, it is impossible for the same thing, in 13 
so far as indivisible and affected in indivisible time, to be moved at 
the same instant with contrary motions. For, if the object be sweet, 
it moves sense or thought in such and such a way, but what is bitter 
moves it in a contrary way, and what is white in a different way. 
A pro- Is, then, that which judges instantaneous in its judgment 

hypo?* 1 anc * numerically undivided and inseparable, although

which is divided which perceives divided objects ; in another sense it 
is qu& indivisible that the divided perceives them : that is to say, logi- 
cally it is divisible, locally and numerically it is indivisible. Or is 14

being is not so, but in actual operation is divided : it is 
impossible that it should be at the same time both white and black, 
and hence impossible that it should receive at the same time the 
forms of white and black, if reception of the forms constitutes 
sensation and thought. Rather is the case parallel to that of 15 
A , the point, as some describe it, which is divisible in so 

Analogy 

of the far as it is regarded as one or two. Well then, in so far 

P m * as the faculty which judges is indivisible, it is one and 

judges instantaneously ; but, in so far as it is divisible, it is not 
one, for it uses the same point at the same time twice. So far as 
it treats the boundary-point as two, it passes judgment on two 
separate things with a faculty which in a manner is separated into 
two ; so far as it treats the point as one, it passes judgment on 
one thing, and that instantaneously. So much, then, for the principle 
in virtue of which we call the animal capable of sensation. 

There are two different characteristics by which the soul is princi- 3 
pally defined ; firstly, motion from place to place and, secondly, 
thinking and judging and perceiving. Both thought and intelli- 
gence are commonly regarded as a kind of perception, since the 
soul in both of these judges and recognises something existent,

also continually a shifting succession of thoughts." Homer's 
meaning, too, is the same when he says : " Such is the mind of 
men." In fact, all of them conceive thought to be corporeal 2

like sensation and hold that we understand, as well as perceive, 
like by like: as we explained at the outset of the discussion. 
This view They ought, however, at the same time to have dis- 
refuted. cussed error, a state which is peculiarly characteristic 
of animal life and in which the soul continues the greater part 
of its time. It follows from their premisses that either all pre- 
sentations of the senses must be true, as some affirm, or contact 
with what is unlike must constitute error ; this being the converse 
of the position that like is known by like. But, as the knowledge 
of contraries is one and the same, so, too, it would seem, is error 
with respect to contraries one and the same. 

Now it is clear that perception and intelligence are not the 3 
same thing. For all animals share in the one, but only a few 
in the other. And when we come to thinking, which includes right 
thinking and wrong thinking, right thinking being intelligence, 
knowledge and true opinion, and wrong thinking the opposites of 
these, neither is this identical with perception. For perception 
of the objects of the special senses is always true and is found 
in all animals, while thinking may be false as well as true 
and is found in none which have not reason also. Imagination, in 4 
fact, is something different both from perception and from thought, 
and is never found by itself apart from perception, any more than 
is belief apart from imagination. Clearly thinking is not the same 
thing as believing. For the former is in our own power, whenever 
we please : for we can represent an object before our eyes, as do 
those who range things under mnemonic headings and picture them 
to themselves. But opining is not in our power, for the opinion that 
we hold must be either false or true. Moreover, when we are of 
opinion that something is terrible or alarming, we at once feel the 
corresponding emotion, and so, too, with what is reassuring. But 
when we are under the influence of imagination we are no more 
affected than if we saw in a picture the objects which inspire terror 
or confidence. There are also different forms even of belief; know- 5 
ledge, opinion, intelligence and their opposites. But the difference 
between these species must be reserved for another discussion.

To turn to thought : since it is different from sense-perception 
imagi- an< 3 seems to include imagination on the one hand and 

nation. conception on the other, we must determine the nature of 
imagination before we proceed to discuss conception. If, then, 6 
imagination is the faculty in virtue of which we say that an image 
presents itself to us, and if we exclude the metaphorical use of the 
term, it is some one of the faculties or habits in virtue of which we 
judge, and judge truly or falsely. Such faculties or habits are sensa- 
Not tion, opinion, knowledge, intellect. It is clearly not 7 

sensation sensation, for the following reasons. Sensation is either 
a faculty like sight or an activity like seeing. But we may have an 
image even when neither the one nor the other is present : for 
example, the images in dreams. Again, sensation is always present, 
but not so imagination. Besides, the identity of the two in actuality 
would involve the possibility that all the brutes have imagination. 
But this apparently is not the case ; for example, the ant, the bee and 
the grub do not possess it. Moreover, sensations are always true,, 
but imaginings prove for the most part false. Further, it is not 
when we direct our energies closely to the sensible object, that we 
say that this object appears to us to be a man, but rather when 
we do not distinctly perceive it \then the term true or false is 
applied}. And, as we said before, visions present themselves even 
if we have our eyes closed. 

Neither, again, can imagination be ranked with the faculties, 8 
nor like knowledge or intellect, which always judge truly : it 

opinion, ma y a i $o b e false. It remains, then, to consider whether 
it be opinion, as opinion may be true or false. But opinion is 
attended by conviction, for it is impossible to hold opinions 
without being convinced of them : but no brute is ever convinced,.

though many have imagination. Further, every opinion implies 
conviction, conviction implies that we have been persuaded, and 
persuasion implies reason. Among brutes, however, though some 
have imagination, none have reason. It is evident, then, that 9 
imagination is neither opinion joined with sensation nor opinion 
through sensation, nor yet a complex of opinion and sen- 
opinion sation, both on these grounds and because nothing- else 

combined ^ 

with is the object of opinion but that which is the object of 

sensation* - T -,-,1 i /--, .. /- 

sensation : I mean, it is the complex of the opinion of 
white and the sensation of white, not surely of the opinion of good 
with the sensation of white, which alone could constitute imagina- 
tion. To imagine, then, will be on this supposition to opine directly, 
not indirectly, that which we perceive. But there are false imagin- 10 
ings concerning things of which we hold at the same time a true 
conception. For example, the sun appears only a foot in diameter, 
but we are convinced that it is larger than the inhabited world : 
in this case, therefore, either, without any alteration in the thing and 
without any lapse of memory on our part or conversion by argument, 
we have abandoned the true opinion which we had about it; 
or else, if we still retain it, the same opinion must be both true and 
false. It could have proved false only in the event of the object 
having changed without our observing it. It is not, then, either 
one of the two, opinion and sensation, singly, or a combination 
of the two, which constitutes imagination. 

Now when one thing is moved, something else can be moved n 
by it. And imagination is thought to be a species of motion and 
not to arise apart from sensation, but only in sentient beings 
and with the objects of sense for its objects. Motion, again, may 
. be produced by actual sensation, and such motion must 

movement resemble the sensation which caused it. From all this 

subsidiary 

to sensa- it follows that this particular motion cannot arise apart 

from sensation nor be found anywhere except in sentient 

beings: and in virtue of this motion it is possible for its possessor to do 

and experience many things : imagination, too, may be both true and

false. The reasons for the last conclusion are as follows. Perception 12 
of the objects of the special senses is true, or subject to the minimum 
of error. Next comes the perception that they are attributes : and 
at this point error may come in. As to the whiteness of an object 
sense is never mistaken, but it may be mistaken as to whether 
the white object is this thing or something else. Thirdly, there 
is perception of the common attributes, that is, the concomitants 
of the things to which the special attributes belong : I mean, 
for example, motion and magnitude, which are attributes of 
sensibles. And it is concerning them that sense is most apt 
to be deceived. But the motion which is the result of actual 13 
sensation will be different according as it arises from one or other 
of these three kinds of perception. The first kind, so long as the 
sensation is present, is true : the other kinds may be false, whether 
the sensation is present or absent, and especially when the object 
perceived is a long way off. If then, imagination possesses no 
other characteristics than the aforesaid, and if it is what 

Imagi- 
nation it has been described to be, imagination will be a motion 

defined. 

generated by actual perception. And, since sight is the 14 
principal sense, imagination has derived even its name (<j>avrao-ia) 
from light (<ao?), because without light one cannot see. Again, 15 
because imaginations remain in us and resemble the corresponding 
sensations, animals perform many actions under their influence ; 
some, that is, the brutes, through not having intellect, and others, 
that is, men, because intellect is sometimes obscured by passion 
or disease or sleep. Let this account of the nature and cause of 
imagination suffice.

CH. 4 429 a 10 429 b 7 131 

As to the part of the soul with which it knows and under- 4 
intellect stands, whether such -part -be separable spatially, or not 
or Mind. separable spatially but only in thought, we have to con- 
sider what is its distinctive character and how thinking comes about. 
Now, if thinking is analogous to perceiving, it will consist in a 2 
being acted upon by the object of thought or in something else of 
this kind. This part of the soul, then, must be impassive, but recep- 3 
tive of the form and potentially like_this form, though not identical 
with it : and, as the faculty of sense is to sensible objects, so must 
mEEltect 'be related to intelligible objects. The mind, then, since 
it thinks all things, must needs, in the words of Anaxagoras, be 
tmmbc^_with_ any, if it is to rule, that is, to know. For by 
'intruding its own form it hinders and obstructs that which is 
alien to it ; hence it has no other nature than this, that it is a 
A poten- capacity. Thus, then, the part of the soul which we call 
*' th^piace intellect (and by intellect I mean that whereby the soul 
of forms." thinks and conceives) is nothing at all actually before 
it thinks. Hence, too, we cannot reasonably conceive it to be 4 
mixed with the body : for in that case it would acquire some par- 
ticular quality, cold or heat, or would even have some organ, as the 
perceptive faculty has. But as a matter of fact it has none. There- 
fore it has been well said that the soul is a place of forms or ideas : 
except that this is not true of the whole soul, but only of the soul 
which can think, and again that the forms are there not in actuality, 
but potentially. But that the impassivity of sense is different from 5 
that of intellect is clear if we look at the sense-organs and at 
sense. The sense loses its power to perceive, if the sensible object 
has been too intense : thus it cannot hear sound after very loud 
noises, and after too powerful colours and odours it can neither 
see nor smell. But the intellect, when it has been thinking on 
an object of intense thought, is not less, but even more, able to 
think of inferior objects. For the perceptive faculty is not in- 
dependent of body, whereas intellect is separable. But when the 6 
intellect has thus become everything in the sense in 
which one who actually is a scholar is said to be so (which 
happens so soon as he can exercise his power of himself), even

then it is still in one sense but a capacity : not, however, a capacity 
in the same sense as before it learned or discovered. And, more- 
over, at this stage intellect is capable of thinking itself. 

Now, since magnitude is not the same as the quiddity of 7 
HOW the magnitude, nor water the same as the quiddity of water 
form or (and so also of many other things, though not of all, the 
is appre- thing and its quiddity being in some cases the same), 
we judge the quiddity of flesh and flesh itself either with 
different instruments or with the same instrument in different 
relations. For flesh is never found apart from matter, but, like 
" snub-nosed," it is a particular form in a particular matter. It is, 
then, with the faculty of sense that we discriminate heat and cold 
and all those qualities of which flesh is a certain proportion. But it 
is with another faculty, either separate from sense, or related to it as 
the bent line when it is straightened out is related to its former self, 
that we discriminate the quiddity of flesh. Again, when we come 8 
to the abstractions of mathematics, the straight answers to the 
quality " snub-nosed," being never found apart from extension. But 
the straightness of that which is -straight, always supposing that the 
straight is not the same as straightness, is something distinct : we 
may, for instance, assume the definition of straightness to be 
duality. It is, then, with another instrument or with the same 
instrument in another relation that we judge it. In general, there- 
fore, to the separation of the things from their matter corresponds 
a difference in the operations of the intellect. 

The question might arise : assuming that the mind is something 9 
some simple and impassive and, in the words of Anaxagoras, 

k as nothing in common with anything else, how will it 
think, if to think is to be acted upon? For it is in 
so far as two things have something in common that the one of 
them is supposed to act and the other to be acted upon. Again, 10 
can mind itself be its own object? For then either its other objects 
will have mind in them, if it is not through something else, but in 
itself, that mind is capable of being thought, and if to be so capable 
is everywhere specifically one and the same ; or else the mind will 
have, some ingredient in its composition which makes it, like the rest, 
an object of thought. Or shall we recall our old distinction between n 
two meanings of the phrase " to be acted upon in virtue of a

common element/' and say that the mind is in a manner 
potentially all objects of thought, but is actually none of them 
until it thinks : potentially in the same sense as in a tablet which 
has nothing actually written upon it the writing exists potentially ? 
This is exactly the case with the mind. Moreover, the mind itself 12 
is included among the objects which can be thought. For where 
the objects are immaterial that which thinks and that which is 
thought are identical. Speculative knowledge and its object are 
identical. (We must, however, enquire why we do not think always.) 
On the other hand, in things containing matter each of the objects 
of thought is present potentially. Consequently material objects 
will not have mind in them, for the mind is the power of becoming 
such objects without their matter ; whereas the mind will have the 
attribute of being its own object. 

But since, as in the whole of nature, to something which serves 5 
T as matter for each kind (and this is potentially all the 

Intellect , v r J 

passive members of the kind) there corresponds something else 
which is the cause or agent because it makes them all, 
the two being related to one another as art to its material, of 
necessity these differences must be found also in the soul. And 
to the one intellect, which answers to this description because it 
becomes all things, corresponds the other because it makes all 
things,' like a sort of definite quality such as light. For in 
a manner light, too, converts colours which are potential into 
actual colours. And it is this intellect which is separable and 
impassive and unmixed, being in its essential nature an activity. 
For that which acts is always superior to that which is acted upon, 2 
the cause or principle to the matter. Now actual knowledge is 
identical with the thing known, but potential knowledge is prior 
in time in the individual ; and yet not universally prior in time. 
But this intellect has no intermittence in its thought. It is, how- 
ever, only when separated that it is its true self, and this, its 
essential nature, alone is immortal and eternal. But we do not

remember because this is impassive, while the intellect which can be 
affected is perishable and without this does not think at all. 

The process of thinking indivisible wholes belongs to a sphere Q 
judgment from which falsehood is excluded. But where both 
or^a- 8 truth and falsehood are possible there is already some 
rates. combining of notions into one. As, in the words of 

Empedocles, " where sprang into being the neckless heads of 
many creatures, 3 ' then afterwards Love put them together, so these 
notions, first separate, are combined ; as, for instance, the notions 
incommensurable and diagonal. And, if the thinking refers to the 2 
past or to the future, the notion of time is included in the com- 
bination. Falsehood, in fact, never arises except when notions 
are combined. For, even if white be asserted to be not-white, not- 
white is brought into a combination. We may equally well call every 
statement a disjunction. But at any rate under truth and false- 
hood we include not only the assertion that Cleon is white, but 
also the assertion that he was or will be. And the unifying prin- 
ciple .is in every case the mind. 

Since, however, the term indivisible has two meanings, accord- 3 
single ' m as a whole is not potentially divisible or is actually 

undivided, there is nothing to hinder us from thinking 
an indivisible whole, when we think of a length (that 
being actually undivided), or from thinking it in an indivisible time. 
For the time is a divisible or indivisible unit in the same way as 
the length thought of. We cannot therefore state what the mind 
thinks in each half of the time. For, if the whole be undivided, 
the half has only potential existence. But, if the mind thinks 
each half separately, it simultaneously divides the time also. And 
in that case it is as if the parts were separate lengths. If, how- 
ever, the mind conceives the length as made up of the two halves, 
then the time may be regarded as made up of corresponding 
halves. 

Again, that which is not quantitatively but specifically an 4

Indivisible whole the mind thinks in an indivisible unit of time and 
by an indivisible mental act. Per accidens^ however, such specific 
unity is divisible, though not in the same way as they, the act of 
-thought and the time required for the act, are divisible, but in the 
same way as they are whole and indivisible. For in these specific 
unities also there is present a something indivisible, though certainly 
not separately existent, the same as that which constitutes the 
unity of both the time and the length. And, as with time and 
length, so in like manner with whatever is continuous. But the 5 
point and every division and whatever is an undivided whole in 
the same sense as the point is clearly explained by the analogy 
of privation. And the same explanation holds in all other cases. 
How, for instance, is evil apprehended, or black ? In some 
fashion by its contrary. But that which apprehends must poten- 6 
tially be, and must contain within itself, the contrary which it 
Hypothe- apprehends. If, however, there be something which has 
think f ing lf " no contrary [some one of the causes'], then it is itself the 
thought. content of its own knowledge, is in actuality and is 
separately existent. 

Now every proposition, like an affirmative proposition, predi- 7 
eating something of something, is true or false. But with thought 
T ^ this is not always so. When its object is the What in 

Intellect J J 

sometimes the sense of the quiddity and there is no predication, 
thought is in every case true. But, as the perception by 
sight of the proper object of sight is infallibly true, whereas in the 
question whether the white object is a man or not, perception by 
sight is not always true, so is it with immaterial objects. 

Now actual knowledge is identical with the thing known. But 7 
potential knowledge is prior in time in the individual, and yet 
not universally prior even in time. For it is from something 
actually existent that all which comes into being is derived. And 
manifestly the sensible object simply brings the faculty of sense 
which was potential into active exercise : in this transition, in 
fact, the sense is not acted upon or qualitatively changed. Conse-

quently this must be a different species of motion. For motion is, 
as we saw, an activity of that which is imperfect ; but activity in 
the absolute sense, that is, activity of that which has reached 
perfection, is quite distinct. 

Sensation, then, is analogous to simple assertion or simple 2 
sense apprehension by thought and, when the sensible thing 

affirming j s pleasant or painful, the pursuit or avoidance of it by 
pursues ' the soul is a sort of affirmation or negation. In fact, 
or avoi s. ^ ^j pleasure or pain is precisely to function with 
the sensitive mean, acting upon good or evil as such. It is 
in this that actual avoidance and actual appetition consist : nor 
is the appetitive faculty distinct from the faculty of avoidance, nor 
either from the sensitive faculty ; though logically they are different, 
so, too, But to the thinking soul images serve as present sen- 3 
the mind. sations i and when it affirms or denies good or evil, it 
avoids or pursues (this is why the soul never thinks without an 
image). To give an illustration : the air impresses a certain quality 
on the pupil of the eye, and this in turn upon something else, and 
so also with the organ of hearing, while the last thing to be impressed 
is one and is a single mean, though with a plurality of distinct 
aspects. 

What that is by which the soul judges that sweet is different 4 
from warm has been explained above, but must be restated here, 
It is a unity, but one in the same sense as a boundary 

The unity J s J 

of sense point, and its object, the unity by analogy of these two 
sensibles or their numerical unity, is related to each of the 
two in turn as they, taken separately, are to each other. For what 
difference does it make whether we ask how we judge the sensibles 
that do not fall under the same genus, or the contraries which do,

like white and black ? Suppose, then, that as A, the white, is to B y 
the black, so C is to D \that is, as those sensible^ are to one anotfier\ It 
follows, convertendo, that A is to C as B to D. If, then, 7 and D are 
attributes of a single subject, the relation between them, like that be- 
tween A and B, will be that they are one and the same, though the 
aspects they present are distinct : and so, too, of their single subject 
The same would hold, supposing A were the sweet and B the white. 

Thus it is the forms which the faculty of thought thinks in 5 

mental images. And, as in the region of sense the objects 
move to of pursuit and avoidance have been defined for it, so also 
ac l n * outside sensation, when engaged with images, it is moved 

to action : as, for instance, you perceive a beacon and say " That is 
fire"; and then \by the central sense\ seeing it in motion, you 
recognise that it signals the approach of an enemy. But at other 6 
times under the influence of the images or thoughts in the soul 
you calculate as though you had the objects before your eyes and 
deliberate about the future in the light of the present. And when 
you pronounce, just as there in sensation you affirm the pleasant or 
the painful, here in thought you pursue or avoid : and so in action 
generally. And, further, what is unrelated to action, as truth and 
falsehood, is in the same class with the good and the evil. Yet in 
this, at any rate, they differ, that the former are absolute, the latter 
relative to some one concerned. 

But the abstractions of mathematics, as they are called, the 7 
Mathe mind thinks as it might conceive the snub-nosed ; 

maticai q u & snub-nosed, it would not be conceived apart from 
how con- flesh, whereas quA hollow, if anyone ever had actually so 
conceived it, he would have conceived it without the flesh 
in which the hollowness resides. So, too, when we think of mathe- 
matical objects, we conceive them, though not in fact separate 
from matter, as though they were separate. And, speaking 8 
generally, mind in active operation is its objects \when it thinks 
them\. The question, whether it is possible for the mind to think 
anything which is unextended without being itself unextended, 
must for the present be postponed.

CH. 8 431 b 20 432 a 14 145 

And now let us sum up what has been said concerning the soul 8 
summary by repeating that in a manner the soul is all existent 
of results. things. For they are all either objects of sensation or 
objects of thought ; and knowledge and sensation are in a manner 
identical with their respective objects. How this is so requires to be 
explained. Knowledge and sensation, then, are subdivided to 2 
correspond to the things. Potential knowledge and sensation 
answer to things which are potential, actual knowledge and sensa- 
tion to things which are actual, while the sensitive and the cognitive 
faculties in the soul are potentially these objects ; I mean, object of 
sensation and object of cognition respectively. It follows that the 
faculties must be identical, if not with the things themselves, then 
with their forms. The things themselves they are not, for it is not 
the stone which is in the soul, but the form of the stone. So that 
there is an analogy between the soul and the hand ; for, as the 
hand is the instrument of instruments, so the intellect is the form 
^ f rms anc * sensation the form of sensibles. But, since, 3 



inteiiectu apart from sensible magnitudes there is nothing, as it 
prius in would seem, independently existent, it is in the sensible 
forms that the intelligible forms exist, both the abstrac- 
tions of mathematics, as they are called, and all the qualities and 
attributes of sensible things. And for this reason, as without 
sensation a man would not learn or understand anything, so at the 
very time when he is actually thinking he must have an image 
before him. For mental images are like present sensations, except 
that they are immaterial. Imagination, however, is distinct from 
affirmation and negation, for it needs a combination of notions 
to constitute truth or falsehood. But, it may be asked, how will 
the simplest notions differ in character from mental images? I 
reply that neither these nor the rest of our notions are images, 
but that they cannot dispense with images.

CH. 9 - 432 a 15 432 b 13 147 

The soul in animals has been defined in virtue of two faculties, 9 
Animal lo- not on ly by its capacit3' to judge, which is the function 
Demotion. o f thought and perception, but also by the local move- 
ment which it imparts to the animal. Assuming the nature 
of sensation and intellect to have been so far determined, we 
have now to consider what it is in the soul which initiates 
motion : whether it is some one part of the soul, which is either 
locally separable or logically distinct, or whether it is the whole 
soul : and again, if a separate part, whether it is a special part 
distinct from those usually recognised and from those enumerated 
above, or whether it coincides with some one of these. A question 2 
Digression at once arises in what sense it is proper to speak of parts 
pSrts^f f the sou ^ an d how many there are. For in one sense 
the soul. there appear to be an infinite number of parts and not 
merely those which some distinguish, the reasoning, passionate and 
concupiscent parts, for which others substitute the rational and the 
irrational. For, if we examine the differences on which they base 
their divisions, we shall find that there are other parts separated 
by a greater distance than these; namely, the parts which we 
have just discussed, the nutritive, which belongs to plants as 
well as to all animals, and the sensitive, which cannot easily be 
classed either as rational or irrational. Imagination, again, is 3 
logically distinct from them all, while it is very difficult to say 
with which of the parts it is in fact identical or not identical, if we 
are to assume separate parts in the soul. Then besides these there 
is appetency, which would seem to be distinct both in concept and 
in capacity from all the foregoing. And surely it is absurd to split 
this up. For wish in the rational part corresponds to concupiscence 
and passion in the irrational. And, if we make a triple division of 
soul, there will be appetency in all three parts, 

To come now to the question at present before us, what is it 4 
that imparts to the animal local movement? For as for the 
motion of growth and decay, which is found in all animals, it 
would seem that this must be originated by that part of soul 
which is found in all of them, the generative and nutritive 
part. Inspiration and expiration of breath, sleep and waking, 
subjects full of difficulty, call for subsequent enquiry. But to 5 
return to locomotion, we must enquire what it is that imparts

to the animal progressive motion. That it is not the nutritive 
The cause faculty is clear. For this motion is always directed to 
motion" an end and is attended either by imagination or by 
SStritive appetency. No animal, which is not either seeking or 
faculty, avoiding something, moves except under compulsion. 
Moreover, if it were the nutritive faculty, plants also would be 
capable of locomotion and thus would have some part instrumental 
nor in producing this form of motion. Similarly it is not 6 

sense, ^ e sensitive faculty, since there are many animals which 

have sensation and yet are throughout their lives stationary and 
motionless. If, then, nature does nothing in vain and, except in 
mutilated and imperfect specimens, omits nothing that is indis- 
pensable, while the animals we are considering are fully developed 
and not mutilated as is shown by the fact that they pro- 
pagate their kind and have a period of maturity and a period of 
decline, it follows that, if locomotion was implied in sensation, 
they would have had the parts instrumental to progression. Nor, 7 
nor again, is it the reasoning faculty or what is called 

intellect, intellect that is the cause of motion. For the specula- 
tive intellect thinks nothing that is practical and makes no assertion 
about what is to be avoided or pursued, whereas motion always 
implies that we are avoiding or pursuing something. But, even if 
the mind has something of the kind before it, it does not forthwith 
prompt avoidance or pursuit. For example, it often thinks of some- 
thing alarming or pleasant without prompting to fear ; the only effect 
is a beating of the heart or, when the thought is pleasant, some other 
bodily movement Besides, even if the intellect issues the order and 8 
the understanding bids us avoid or pursue something, still we are 
not thereby moved to act: on the contrary, action is determined 
by desire ; in the case, for instance, of the incontinent man. And 
generally we see that, although a man possesses a knowledge of 
medicine, it does not follow that he practises ; and this implies 
that there is something else apart from the knowledge which deter- 
mines action in accordance with the knowledge. Nor, 
potency again, is it solely appetency on which this motion de- 

sol el v 

pends. The continent, though they feel desire, that is 
appetite, do not act as their desires prompt, but on the contrary 
obey reason.

The motive causes are apparently, at any rate, these two, either 10 
appetency or intelligence, if we regard imagination as 
ne s P ecies of thinking. For men often act contrary to 
practical knowledge in obedience to their imaginings, while in the 
other animals there is no process of thinking or reason- 
ing, but solely imagination. Both these, then, are causes of loco- 
motion, intelligence and appetency. By intelligence we mean that * 
which calculates the means to an end, that is, the practical intellect, 
which differs from the speculative intellect by the end at which 
it aims. Appetency, too, is directed to some end in every case : for 
that which is the end of desire is the starting point of the practical 
intellect, and the last stage in this process of thought is the start- 
ing point of action. Hence there is good reason for the view that 
these two are the causes of motion, appetency and practical thought. 
For it is the object of appetency which causes motion ; and the 
reason why thought causes motion is that the object of appetency is 
the starting point of thought Again, when imagination moves to 3 
action, it does not move to action apart from appetency. Thus there 
is one single moving cause, the appetitive faculty. For, had there 
been two, intelligence and appetency, which moved to action, still 
they would have done so in virtue of some character common to both. 
But, as a matter of fact, intellect is not found to cause motion 
apart from appetency. For rational wish is appetency ; and, when 
anyone is moved in accordance with reason, he is also moved 
according to rational wish. But appetency may move a man in 
opposition to reason, for concupiscence is a species of appetency. 
While, however, intellect is always right, appetency and imagina- 4 
tion may be right or wrong. Hence it is invariably the object of 
appetency which causes motion, but this object may be either the 
good or the apparent good. Not all good, however, but practical 
good : where by practical good we mean something which may 
not be good under all circumstances. 

It is evident, then, that motion is due to the faculty of the 5 
soul corresponding to this object I mean what is known as ap- 
petency. But those who divide the soul into parts, if they divide 
it according to its powers and separate these from one another, 
will find that such parts tend to become very numerous : nutritive,

sensitive, intelligent, deliberative, with the further addition of an 
appetent part : for these differ more widely from one another than 
the concupiscent does from the passionate. Now desires arise 6 
conflict of which are contrary to one another, and this occurs when- 
desires. ever reason and the appetites are opposed, that is, in 
those animals which have a perception of time. For intelligence 
bids us resist because of the future, while appetite has regard 
only to the immediate present ; for the pleasure of the moment 
appears absolutely pleasurable and absolutely good because we do 
not see the future. Therefore, while generically the moving cause 
will be one, namely, the faculty of appetency, as such, and ultimately 
the object of appetency (which, without being in motion itself, causes 
motion by the mere fact of being thought of or imagined), numeri- 
cally there is a plurality of moving causes. 

Now motion implies three things, first, that which causes motion, 7 

secondly, that whereby it. causes motion, and again, 
animal thirdly, that which is moved ; and of these that which 

causes motion is twofold, firstly, that which is itself 
unmoved and, secondly, that which both causes motion and is 
itself moved. The unmoved movent is the practical good, that 
which is moved and causes motion is the appetitive faculty (for 
the animal which is moved is moved in so far as it desires, and 
desire is a species of motion or activity) and, finally, the thing 
moved is the animal. But the instrument with which desire moves 
it, once reached, is a part of the body : hence it must be dealt with 
under the functions common to body and soul. For the present, 8 
it may be enough to say summarily that we find that which 
causes motion by means of organs at the point where beginning 
and end coincide ; as, for instance, they do in the hinge-joint, for 
there the convex and the concave are respectively the end and the 
beginning, with the result that the latter is at rest, while the former 
moves, convex and concave being logically distinct, but locally in- 
separable. For all animals move by pushing and pulling, and 
accordingly there must be in them a fixed point, like the centre in

a circle, and from this the motion must begin. Thus, then, in 9 
general terms, as already stated, the animal is capable of moving 
itself just in so far as it is appetitive : and it cannot be appetitive 
without imagination. Now imagination may be rational or it may 
be imagination of sense. Of the latter the other animals also have 
a share. 

We must also consider what is the moving cause in those im- 11 
The low- perfect animals which have only the sense of touch* Is 
ofhfe^ow fr possible that they should have imagination and desire, 
moved. or i s j t not p i t i s evident that they feel pleasure and 
pain : and, if they have these, then of necessity they must also 
feel desire. But how can they have imagination? Shall we say 
that, as their movements are vague and indeterminate, so, though 
they have these faculties, they have them in a vague and indeter- 
. minate form ? The imagination of sense, then, as we a 

have said, is found in the other animals also, but delibe- 



nation. . - , , . , ., 

rative imagination in those alone which have reason. 
For the task of deciding whether to do this or that already implies 
reasoning. And the pursuit of the greater good necessarily implies 
some single standard of measurement. Hence we have the power 
of constructing a single image out of a number of images. And 
the reason why the lower animals are thought not to have opinion 
is that they do not possess that form of imagination which comes 
from inference, while the latter implies the former. And so ap- 3 
petency does not imply the deliberative faculty. But sometimes it 
overpowers rational wish and moves to action ; at other times the 
latter, rational wish, overpowers the former, appetency. Thus one 
appetency prevails over another appetency, like one sphere over 
another sphere, in the case where incontinence has supervened. 
But by nature the upper sphere always has the predominance and 
is a moving cause, so that the motion is actually the resultant of 
three orbits.

The cognitive faculty, however, is not subject to motion, but is 4 

at rest. The major premiss is universal, whether judg- 
practicai ment or proposition, while the minor has to do with a 
S y ogism. p ar ti cu i ar f ac t : for, while the former asserts that such and 
such a person ought to do such and such an act, the latter asserts 
that a particular act is one of the sort and that I am such a person. 
Now it is the latter judgment which at once moves to action, not the 
universal. Or shall we say that it is both together, but the one is 
akin to the unmoved movent, the other is not ? 

Every living thing, then, must have the nutritive soul and in fact 12 
Teleology: has a sou l from its birth till its death. For what has 
been born must necessarily grow, reach maturity and 
decline, and for these processes nutriment is indispens- 
able. It follows, then, of necessity that the nutritive faculty is 
present in all things that grow and decay. But sensation is not 2 
necessarily present in all living things. For wherever the body is 
uncompounded there can be no sense of touch {yet without this sense 
animal existence is impossible\ : nor, again, in those living things 
which are incapable of receiving forms apart from matter. But 3 
the animal must of necessity possess sensation, if nature 

Sensation . - . 

necessary makes nothing in vain: for everything in nature sub- 
to animals. , 1 . t1 - - - . 

serves an end or else will be an accessory of things 

which subserve an end. Now every living body having the power 
of progression and yet lacking sensation would be destroyed and 
never reach full development, which is its natural function. For 
how in such a case is it to obtain nutriment ? Motionless animals, 
it is true, have for nutriment that from which they have been 
developed. But a body, not stationary, but produced by genera- 4 
tion, cannot possibly have a soul and an intelligence capable of 
judging without also having sensation. \_Neither can it y if it be not 
generatedl\ For why should it have the one without the other? 
Presumably for the advantage either of the soul or of the body. 
But neither of these alternatives is, in fact, admissible. For the 
soul will be no better able to think, and the body will be no 
better off, for the absence of sensation. We conclude, then, that no 
body that is not stationary has soul without having sensation.

But, further, the body, assuming that it has sensation, must 5 

be either simple or composite. But it cannot be simple, 
necessary for then it would not have touch, and this sense is indis- 
preserva- pensable. This is clear from the following' considerations. 6 

The animal is an animate body. Now body is always 
tangible and it is that which is perceptible by touch which is tan- 
gible : from which it follows that the body of the animal must have 
tactile sensation, if the animal is to survive. For the other senses, 
that is to say, smell, sight, hearing, have media of sensation, but 
a being which has no sensation will be unable when it comes into 
contact with things to avoid some and seize others. And if 
this is so, it will be impossible for the animal to survive. This 7 
is why taste is a kind of touch, for taste is of nutriment and 
nutriment is body which is tangible; whereas sound, colour and 
smell afford no nourishment and promote neither growth nor 
decay. So that taste also must be a kind of touch, because it is 
a sensation of that which is tangible and nutritive. These two 
senses, then, are necessary to the animal, and it is plain that 
without touch no animal can exist. 

But the other senses are means to well-being, and are necessary, 8 
The higher not to any and every species of animal, but only to cer- 

tain species, as, for example, those capable of locomotion. 

For, ^ ^ e ar *imal capable of locomotion is to survive, it 
animals. must have sensation, not only when in contact with any- 
thing, but also at a distance from it. And this will be secured if it 
A medium can perceive through a medium, the medium being capable 
forsenss^ ^ being acted upon and set in motion by the sensible 
tion. object, and the animal itself by the medium. Now that 9 

which causes motion from place to place produces a change oper- 
ating within certain limits, and that which propels causes the thing 
propelled to propel in turn, the movement being transmitted 
through something intermediate. The first in the series initiates 
motion and propels without being itself propelled, while the last 
is simply propelled without propelling; the numerous middle 
terms of the series both propel and are propelled. So it is also 
with qualitative change, except that what is subject to this 
change remains in the same place. Suppose we were to dip 
something into wax, the movement in the wax would extend just 
so far down as we had dipped the object, whereas in the like case

a stone is not moved at all, while water is disturbed to a great 
distance and air is disturbed to the farthest extent possible and acts 
and is acted upon as long as it remains unbroken. And, to revert 
to the reflection of light, that is why, instead of holding that the 
visual ray leaving the eye is reflected, it would be better to say that 
the air is acted upon by the shape and colour, so long as it is one 
and unbroken. This is the case over any smooth surface : and ac- 
cordingly the air acts on the organ of sight in turn, just as if the 
impress on the wax had penetrated right through to the other side. 

It is evident that the body of an animal cannot be uncom- 13 
A mixture pounded ; I mean, it cannot consist entirely of fire, for 
efemeSts 1 instance, or of air. An animal, unless it has touch, can 
STtScfSi- h ave no other sense, the animate body being always, as 
mai body. we have remarked, capable of tactile sensation. Now the 
other elements, with the exception of earth, would make sense- 
organs : but it is always indirectly and through media that such 
organs effect sensation. Touch, however, acts by direct contact 
with objects : hence its name. The other sense-organs, it is true, 
also perceive by contact, but it is by indirect contact : touch alone, 
it would seem, perceives directly in and through itself. Thus, then, 
no one of the three elements referred to can constitute the body of 
the animal. Nor indeed can it be of earth. For touch is a sort 
of mean between all tangible qualities, and its organ is receptive 
not only of all the distinctive qualities of earth, but also of heat 
and cold and all other tangible qualities. And this is why we 
do not perceive anything with our bones and our hair and such 
parts of us, namely, because they are of earth. And for the same 
reason plants, too, have no sensation, because they are composed 
of earth. Without touch, however, there can be no other sense ; 
and the organ of this sense does not consist of earth nor of any 
other single element. 

Thus it is evident that this is the only sense the loss of which 2 

necessarily involves the death of the animal. For it is not possible 

for anything that is not an animal to have this sense, nor is it 

necessary for anything that is an animal to have any other sense 

besides this. And this explains another fact. The other 

Why * 

tangibles sensibles I mean, colour, sound, odour do not by their 

destroy excess destroy the animal, but only the corresponding 

sense-organs : except incidentally, as when concurrently

with the sound some thrust or blow Is given, or when objects of 
sight or smell move something else which destroys by contact 
Flavour, again, destroys only in so far as it is at the same time 
tactile. Tangible qualities, on the other hand, as heat, cold and 3 
hardness, if in excess, are fatal to the living animal. For excess 
of any sensible object is fatal to the organ, and so consequently 
excess of the tangible object is fatal to touch. And it is by this 
sense that the life of the animal is defined, touch having been 
proved to be indispensable to the existence of an animal. Hence 
excess in tangible qualities destroys not only the sense-organ, but 
also the animal itself. For touch is the one sense that the animal 
The cannot do without. The other senses which it possesses 

seises are, as we have said, the means, not to its being, but to 



its well-being. Thus the animal has sight to see with, 
being. because it lives in air or water or, speaking generally, 

in a transparent medium. It has taste on account of what is 
pleasant and painful, to the end that it may perceive what is 
pleasant in food and feel desire and be impelled to movement. It 
has hearing in order that information may be conveyed to it, and 
a tongue, that in its turn it may convey information to its fellow.

NOTES. 

BOOK I. CHAPTER L 

<4O2 a 1 2222. In this introductory chapter A. first touches upon the 
importance and utility, especially for physics, of an enquiry into the soul, and 
next enlarges upon the difficulties besetting such an enquiry. Its object is to 
determine the nature of the soul and its essential attributes [ i]. There is the 
general logical difficulty, viz., the absence of any uniform recognised method of 
obtaining definitions and the uncertainty as to the premisses from which the 
investigation should start [ 2]. 

402 a i Twv...4 Ti6eti]|jiv. Universam hanc periodum sic recte inter- 
preteris : Quarum rerum cognitio pulchra et honore digna est, earum etiam 
investigatio est pulchra et honore digna : quarum igitur ilia magis est honore 
digna, earum et haec. At pulcherrima facile est animae cognitio : pulcherrima 
igitur etiam investigatio eius quid sit (Torstrik, p. 112). According to Philop. 
(24, 3 sqq., 17 sqqO these apparently harmless propositions caused Alex. Aphr. 
so much perplexity that he condemned as spurious the whole passage a i paXXov 

,..3 elvai and explained Si" a^orepa rarira as Sia ro Ka\r)V K.al rtfMLav etvai. If the 
report is correct, Alexander's suspicions must have been aroused because he 
supposed the supremacy of metaphysics to be challenged and even the place 
claimed for psychology among the natural sciences to be inconsistent with 
such passages as, e.g., Eth. JVic. 1141 a 33 b 2. See note on 402 a 4 4v 
irpwrois. 

a i. TWV icoXav Kal Tijifov TPV ctS-rjo-iv. The partitive genitive becomes a 
predicate here after v7ro\ap{3dvoi>Ts. This is fairly common with to/at, e.g. 
infra 402 a IO ccrri T&V ^aXcTrcordrcDv, 417 a 24, 422 a 6. So also with yiyvea-Oai, 
Pol. 1304 a 1 6 yev6jjLvos TG>V dpx6vT<w, as in other writers ; with iroietv, Rhet. u. 
23 II, 1398 b 13 AaK8ai/j,6vioi XtXo>i>a r>v yepovrav eiroirj<rav ; with nQ^vai^ 
TiQea-Qai, ypdcfreiv [Kiihner-Gerth, Gr. Gr. 418, p. 375]. After tJ7roXa/jL/3ai/iv 
A. omits upon occasion the infinitive [here i/at], thus converting the verb into 
one of incomplete predication, and assimilating its construction to that of T&ivai 
(405 b 1 8, 26), TiQevQai (405 a 15), ITOLCIV (404 b 10, 31, 405 b 13 sq., 19), KaXelv 
(405 b 28 sq.) when similarly used. Thus, to confine ourselves to I., c. 2, the 
infinitive elvai after V7ro\afj.(3dvei,v is found 403 b 31, 404 a 8, 22 sq. and omitted 
404 b 8, 405 a 5, 20, b 7. The same freedom of construction is permitted with 
Xeyetv, see 404 a 5, 21 compared with 26. For TI\L(G>V cf. 430 a 18 sq., Zte Part. 
An. I. 5, 644 b 22 645 a i, Metaph. 1074 b 21 (where it is an attribute of vovs) 7 
26, 30 (where it is applied to the object of thought). 

The rare word ctSTjo-is is apparently used by A. here only. It may be his 
own coinage, for, though occurring in Theophrastus (e.g. frag. LXXXIX. 4), in 
scholiasts on Homer and Sophocles, and, as might be expected, in commentators 
like Philop., it seems to have found little favour. Later it was affected by 
Clement of Alexandria and Sextus Empiricus. Hesychius explains it by yvS><Ti$, 
and like yvSxri^ 402 a 5, it is a comprehensive, general term for knowledge of

arranging kinds of knowledge in a scale of increasing dignity or intrinsic worth. 
Thus in Metapk. 980 a 27 981 a 12 and AnaL Post. IT. 19, 99 b 34 100 a 9 
we have such a scale of knowledge rising from sense-perception through 
memory and experience to art, and finally to science (<?V 10-1-77/^7). The sciences 
themselves are variously classified. See AnaL Post. I. 13, 78 b 34 79 a 6. 
In Metaph. 1026 a 18 23 a scheme of three theoretical sciences is projected in 
outline, First Philosophy (called ^eoXoyt/c^) is the highest, next comes Mathe- 
matics, next Physics, 1064 b i 6. Cf. Top. vm. i, 157 a 8 TO de faaipctcrQai

a 2. Ko/r 1 etKpCpeiav. The meaning of the term varies according as it is 
applied to aTrd&et^s 1 or iri<rrf)prj. (i) The rigorous accuracy of a demonstration 
depends upon the correctness of the reasoning and the truth of the premisses, 
In sciences which deal with the contingent it often happens that premisses and 
therefore conclusions are only general, not universal, truths. The rigorous 
accuracy of mathematical proof is not to be looked for in ethics (Eth* NIC. 
1094 b ii 27) because the premisses are contingent. Cf. 1104 a i 6. In this 
sense all scientific reasoning and all theoretical science is exact, and to a*/n- 
/Se'crrepov SCIKVVVCU, Metaph. 1064 a 6 sq., is opposed p,a\aK.&Tpov &etKi/vi/cu, to 
reason loosely or inconclusively. But (2) in another sense dKpiftrjs is applied 
to a science or knowledge in respect not of the proof but of the method 
of treatment employed. It then means "abstract," like dTrXofo, and it is 
implied that the objects with which such a science deals are themselves 
by comparison more abstract, more simple and logically prior ; for aKplfteia 
is a relative term. Thus of First Philosophy, the highest of the sciences, 
and also the most abstract, A. says (Metaph. 982 a 25) : " Those amongst 
the sciences are most exact which have especially to do with the first 
causes, for the sciences which start from fewer premisses are more exact 
than those which are complicated with additional determinations : Arith- 
metic, for example, is more exact than Geometry." On this Bonitz ad loc^ 
"aKp//3etav sive exactam et omnibus numeris perfectam cognition em turn maxime

postulated in all the rest; Arithmetic regards its objects as numerable, but 
takes no account of extension; Geometry complicates its investigations by 
regarding its objects, CK Trpoo-tfeo-eow, not only as numerable, but also as ex- 
tended. All mathematical sciences are more abstract than the physical sciences, 
for the former treat their objects as unmoved, while physics takes account 
of motion. Optics does not deal with the physiological properties of vision, 
nor harmonics with those of voice : the former treats the ray of light as a line, 
the latter a chord as the ratio of two numbers : and so on. It often happens 
that the more abstract science discovers the cause which is necessary to explain 
the facts investigated by a more concrete science. AnaL Post. I. 27, 87 a 31

last is the most fundamental and that the others rest upon it. Trendelenburg's 
translation " quod vel acrius ingenii acumen requirit " has no sort of justifi- 
cation, and the discrepancy which he discovers between these words and 
a 10 is imaginary. First philosophy is at once the most abstract and the 
most difficult of the sciences (Metaph. 982 a 24 sq.), and psychology presents 
more difficulties than the other biological sciences precisely because it is 
more abstract than the rest. Its a/cp#?eia is relative. In AnaL Post. II. 19, 
99 b 33 A. speaks hypothetically of a (dvvajus) TOVT&V rifueorepa *car' aKpiftsiav, 
and ib. 99 b 27 of aKptfavrepas yvd>(ri? d7rodfigea>?. Of course as a matter of

a 2 4j r$...3 etvai. The subject-matter (TO eVtcrnjToV, the province or yfros 
with which the science deals) also helps to determine the place of a science in 
the scale, quite independently of the question whether the treatment is abstract 
or concrete. For this reason in the realm of Nature the sciences which deal 
with the Trpcorov crT-ot^eloi/, &<t>6apTOv, dycvrjrov, KvxXtp <poprjr6v 9 rank higher than 
the rest : De Cael. ill. r, 298 b 6 sqq. Cf. Metaph. 1026 a 21 KOL TTJV n/zicaranjv

pressing the object of a cognition, as of any other mental act, may be freely 
illustrated from the terminology of this treatise in reference to sensation and 
the sensible object. Cf., e.g., 418 a 13, 26, 421 b 4 -6, 422 a 2029, 422 b 23

(aKpifteia) and for the importance of its subject-matter. In this treatise our 
subject is ro eptyvxw $v 27 p*lrvxov, and we deal preeminently with the form

If there is a science of soul it must conform to the conditions laid down in 
Anal. Post, for all sciences and particularly for all physical sciences, as it is 
plainly a branch of physics. On the formal side the main work of the enquirer 
will be to delimit his province, to define it and to deduce the essential properties :

de ordine doctrinae, ibi de 'via, non de ordine. Z. further maintains that this 
programme is so far carried out that the whole of De A. treats properly of the 
ri fern, the nature of soul, its crvfjLpefirjKora or accidents being reserved for the 
Parva Naturalza* appealing to De Sensu 436 a i 5. But Z. is obliged to admit 
that in in. cc. 48 the treatment of intellect is exhaustive, including properties 
as well as essential nature. There is no need to lay such stress on this formal 
division of the task before us. Every science must delimit its y'z/os-, and define 
its subject, before it can proceed to deduce the essential properties : Metaph. 
1003 a 21 26, b 19 22, 1004 b 58, 1017, 1025 b 3 sqq., esp. b 5 13 and 
1063 D 36 1064 a 7, which is a convenient summary of Metaph. E. i.

Kara o~vp(3pT)KQs i'Swx ( = properties). The usual example is the property of a 
triangle that its angles are equal to two right angles (402 b 20). This forms no- 
part of the definition, but can be deduced from it. Ind. Ar. 713 b 43 inde 
crv^aiveiv, avp^^7j<vai, o-uppeprjkos id dicitur, quod cum non insit ipsi alicuius- 
rei notioni, tamen concludendo ex ea necessario colligitur. It is not enough 
that a science should delimit its province and obtain a definition. From this 
definition it must deduce all the essential properties of the subject under investi- 
gation. We shall presently see (402 b 16 403 a 2) that essence and properties 
are mutually implicated, and that in some cases the study of the property is the 
best road to the determination of the essence. In this treatise there are various 
designations and enumerations of the attributes of soul (or, more correctly, 
of the animate being which possesses the soul qu& animate), e.g. pya KOI irddr] 
(409 blS, cf. 407 b 1 8), evepyeiai <al Trpdfeis (415 a 19), iradrnLora (403 a II, cf. 
403 a 5 7, 1 6 1 8, 411 a 26 b 5). Cf. De Sensu i, 436 a i 18. They are 
seldom styled o-v/i/SejSTjKora. See, however, 409 b 14. In general terms, what- 
ever the possessor of soul does or suffers in virtue of such possession, 411 b 2 sq. 
TTOLovjjiev re KOI IT ao")(o\t.v ( c f- 43 a 6 sq. Tcaxr^eiv ov8e 7rotiv), A. regards as a

In this well-established sense <7Vftj3e/9j;Kop=(rv^tj3. <aff avro, But the term is 
ambiguous, and is more commonly used by A. to denote something quite 
different, i.e. an accident, a purely fortuitous attribute, white and musical in 
man being the stock instances (Ind. Ar. 714 a 20). As o-vju^e^jedra in this 
latter sense are never necessary, are neither universal nor even general attri-

definition. It might be any rough description sufficient to identify the thing in 
question provided it excluded everything merely unessential or accidental, 
leaving only what is dvayKalov. Thus the genus will answer the question ri 
CO-TI, but without the differentia would not be a complete definition. See below

and in projecting the organisation of a new department of enquiry, the defect 
here mentioned, the want of a short and easy road to definitions, would naturally 
be felt. Kara c. gen. is used after clvat and vsrap^civ, and even after K.OIVQV, in 
much the same sense as after verbs of predication, Xc'yeo-tfai, KaT^yo/^icr&u, the 
technical expressions Ka66\ov and Kara iravrbs (AnaL Post. I. 4, 73 a 28 sqq.)

But, in view of Torstrik's citations, even the hypothetical mention of aTrdSetfw 
in this connexion needs some qualification, and rw="of a sort" is half ironical, 
half apologetic. The relation of demonstration to definition is fully discussed 
in Anal. Post. II. cc. i n. The two processes are wholly dissimilar. It is 
impossible to demonstrate essence or to obtain a definition by demonstration 
alone. All such attempts involve a petitio principii. Cf. Anal. Post. II. 3, 
especially 90 b 18 91 a 8, ib. II. 7, 92 b 35 39, ib. II. 8, 93 b 15 20. But 
where to know what a thing really is is the same as to know why it is (Anal. 
Post. II. 2, 90 a 15, 31), and the question, "What is the real nature of a thing?" 
can be interpreted to mean, "What is the cause which makes the thing what it 
is?," then the search for definitions becomes virtually a search for causes in 
which demonstration and the syllogism play an important part: AnaL Post.

Metaph. 1037 b io sqq. : all we show is that (ort), or why (tort) an attribute can 
be predicated of a subject. In other words, given a knowledge of the facts 
(TO ort) and the cause (TO &OTI), the definition can be discovered and recognised 
as such, and the practical rules laid down employ demonstration, especially 
demonstration a posteriori of the cause from the effect, and demonstration that 
the elements of the definition are essential attributes of the definiend.

a petitio principiL But in his own practical rules A. employs division as a

suppositions are not seriously meant, it is unimportant what the reference

we fall back presumably upon sense-perception and induction : see note on

definition of soul and the investigation of its essential properties are : (i) To what 
category does the soul belong? (2) Is it potentially or actually existent? [ 3] 
(3) Is it divisible or indivisible? (4) Is it throughout homogeneous? If not, 
does the difference between soul and soul amount to a difference of genus or 
only of species ? In contemporary discussion the soul of man stands for soul in

we rest content with definitions of the several species of soul ? [ 5].

bear in mind that of the four significations of the ambiguous term Being or oV

413 b ii 414 a i, 432 a 22 b 7, does not admit of an unqualified answer. It 
depends upon the meaning we assign to the term part and Its correlative whole 
(cf. Metaph. A. 25 sq.). Speaking generally, peprj^els a SiaipciTat KOL 1% <av

Any quantity (TTOO-OV) has quantitative parts : in this sense part is not applicable 
to the soul, if it is neither ptycQos (407 a 2sq.) nor TTOO-OV at all (410 a 21). Cf. 
Alex., De A. 30, 29 r\ de faxy ov povov oi>x &s /teyt^os-, aXX* ovS* a>s apiBpos tm

returns to this question 413 b 13 sqq., 429 a 11, he contrasts the logical dis- 
tinctness of the parts, their separateness to thought (Xoyc> -erfpa, ^6>pto-ra) with

phenomena of life in all its other forms, including plants. Obviously the 
solution of the present problem presupposes a comparative study of all species 
of animals and (cf. 41 ib 27 sq.) plants. For A.'s own procedure the precept

think the criticism is aimed at Plato, especially in the Timaeus, where, however, 
the soul even of the plant is distinctly recognised (77 A, B), and everything 
which partakes of life is declared to be a f<5ov and to have some sort of soul. 
Philop. 36, 1 6 sqq. takes the reference to be general, including Democritus and 
the other physicists. 

b5 Tn$Tpov ts...8 -fj vorepov. Knowledge is of the universal, definition 
of the universal, i.e. the form (Metaph. 1036 a 28 sq.). Particular souls and 
particular animals 4iff er s but all animals belong to the genus animal, though 
they also belong to different species, horse, man, dog. Is, then, the genus 
animal the type of universality by which soul is known and defined, or shall we 
seek distinct definitions of the species ? The settlement of this question will 
have a direct bearing on procedure. If we take the first alternative, a study of 
the genus, in which are united all the common characteristics of soul, will 
precede the study of the different varieties. If we favour the second alternative, 
the study of the varieties should come first, for the genus is a logical entity and 
not the constitutive form of any of the particulars of which it is predicated. It 
is part of that form and part only. There is another view of the passage. 
Some take it that the preceding question is presumed to be decided in the 
sense that the difference between souls is a specific and not a generic difference, 
so that it only remains to consider what is the nature of the genus to which 
they all belong. It may be (i) such that they are, in technical language, 
(^tllf^v^;/za (2w TO re ftvofjua K.OIVOV KOI 6 \6yos 6 auros, Cat. I. I a 6). If not, they 
are either (2) o^wovv/uta, having nothing in common but the name, or (3) trpos cv 
\cy6p,va, forming a ycvos KCLT* avoXoyiW, of which cv and oi' are examples. It is 
assumed that animal cannot illustrate both alternatives : it cannot, as genus, be 



I. I 402 b 2 b 5 185 

the object of a single definition and at the same time be the non-existent or 
posterior universal of particulars which admit of several definitions. Hence it 
is inferred that in the second alternative animal replaces soul and that what is 
said of it is only true of animal in a supposed and not an actual case : in other 
words, that soul, unlike animal, is not a genus, because souls form a series, 
and such a class is destitute of true generality. Alex. Aphr. first gave this 
explanation, though he afterwards modified or retracted it. He tells us (air. KCU 
XiV., pp. 22, 23sqq.) that in his lost commentary on De A. he had shown that 
A. may possibly have used <5oi/ as an example to illustrate the different species 
of soul regarded as related in a definite order of succession (22, 24 sq.). If so, 
Alex, considered, the example chosen would be fictitious. If man, horse, dog 
were not o/xoyej/?;, were not, as they are, species of the one genus f<Sor, each of 
them would require to be separately defined, and either the common term 
" animal " as applied to all of them would denote no characteristic nature (oiK.da 
<f>v<rii), but would be employed in an ambiguous or equivocal sense, or, if there 
were anything objective corresponding to it, it would be like a term of various 
meanings, of which one is always prior to the other, ra TroXXax&r Xeyd^ej/a eV ols

of succession. [Examples are found in the numerical series 2, 3, 4, etc., in 
rectilinear figures (Metaph. 999 a 6 sqq.) and in constitutions (Pol. 1275 a 
34 sqq.) : probably also in such notions as -uytetrov and ayaBov. The common 
characteristic is present in varying degrees in different members of such a class, 
being hardly discernible in some : Pol. 1275 a 37 9 ro rrapdirav ouS" evecmv, $

This, the earlier explanation of Alex., is accepted amongst others by Zabarella, 
who argues that in Book II. A. declares soul to be commune quid analogum, 
and therefore its generic definition is insufficient : we need the specific 
definitions of the several parts of soul in order to complete our knowledge. 
According to him, animal is genus univocum, soul is genus aualogum with 
nothing objective answering to it except the name and the individual souls. 
Hence the definition of animal gives some information, though incomplete ; 
the generic definition of soul gives no knowledge, unless accompanied by the 
knowledge of the several parts of soul. The obvious defect in this explanation 
is the choice of a fictitious example. To remedy this defect Alex, proposes 
to show (OTT. KOI Xucr., 21, 19 ; 23, 21) that after all A.'s words tj oitdev SOTLV rj 
v<rrpov are true of animal and of genera properly so called, provided that we 
carefully distinguish between <pov = ova-La 6/n/n^off aftrdqmeq, which is something 
existent, a thing with attributes (6V TL irpaypa\ and TO o>r y4vos <T<oi>, animal as 
genus or universal, which is properly nothing but merely an attribute of things 
(riv>v ovy (rviAJSefirjKos Trpay/xaT*, <rvfj,7rrG>fj.a firi rwt, ytvofifvov TT pay part) . Strictly 
the genus is not 6V TI, but, if by courtesy we include it among ovra, it is 
decidedly posterior logically to the individual members which belong to it. 
This Alex, proves in the usual way. Suppose the genus animal annulled in 
thought, this would leave unaffected the existence of particular animals, whereas 
the destruction of the members of the genus necessarily implies that the genus 
ceases to exist. Here, it will be observed, he comes to a conclusion concerning 
the true genus diametrically opposite to that which he had previously reached 
in his commentary on the De A., viz. (23, ir) TO /xev yap obr yc^os- nvcov Karrjyo-

first stated for soul, animal being adduced as an illustration, while afterwards 
A. goes on to speak of animal, the illustration, leaving soul out of sight. But 
to lose the immediate subject in the illustration is quite in A.'s manner. Cf. 
403 a I2sqq., 431 a 17 sqq. Further, there is good reason why he should begin 
with soul and continue with animal ; for the latter term is in his view equally 
applicable to both ; at any rate he allows such a view to be tenable. Cf. 
Metaph. 1043 a 34 KOL <$ov Trorepov ^vxn ev crapon, 77 ^11^17... eLrj d* av KOL eV

such a double application is impartially admitted Metaph. 1036 a 16 19, 24 sq., 
1037 a 5 10. When we speak of defining, it is always with the tacit assumption 
that the particular, as such, the compound of form and matter which is perish- 
able and subject to change, is incapable, properly speaking, of being defined : 
Metaph. 1039 b 20 1040 a 7. If animal denoted an infima species instead of a 
genus, the identity of animal and soul for the purpose of definition would be 
complete ; but this is not the case. Animal, as universal, like man as universal, 
denotes a class which, like its individual members, is a o-vvo\ov or compound of 
form and matter, form capable, matter incapable, of definition : Metaph. 1035 b 
27 30, 1037 a 5 7. Such a class is not ova-La (1035 b 28, 1038 b 8 16, 35), 
for it denotes not i-o'd* n but roidvde (1039 a i sq., 16). This is what A. means 
by rj ovbev ecmv=iQVK. cmv ovfrLa rov cpov rov K.aB6\ov. As a mere universal 
notion or class-name, animal denotes the common characteristic or charac- 
teristics by which species are combined in a genus ; and similarly man, as 
mere universal, denotes the common characteristic or characteristics by which 
particular men are combined in an infima species. In other words, animal is 
neither ev irapa ra TroXXa nor Iv eVi TToXXaiv, but simply ti> Kara TroXXcai/ or KOivfj 
Karr)yopov/Mvov (402 b 8). Nevertheless, it is ov rt, a logical entity, owing its 
existence to thought : cf. Philop. 38, 3 e^c* yap rr\v vTroorraa-tv eV T<5 voctcrdac, <> 
pevroi *ea0* aurb vfaorrjKOS ovdev eo-rt. As thus described, it is v&repov, posterior 
to every member of the class, to every possessor of the characteristic or charac- 
teristics which it predicates as held in common : for naBy are necessarily 
posterior to ova-Co. ; otherwise they would exist independently, apart from ova-la 
{Metaph. 1038 b 23 29). 

But it may be urged that elsewhere icatfoXov is described as Kara travr6s^ Ka0* 
avrd, $ avro. Anal. Post. I. 4. 73 b 26 sq., whereby it is given a place *v r< rt 
carnv, and that yivos is part of the definition and, as such, prior to the definition 
of which it is a part (Metaph. 2. c. 10, especially 1034 b 31 sq., 1035 b 14 20). 
We cannot define man, horse, dog, if we do not know animal, which forms part 
of the definition of each of these species. A. himself allows full weight to this 
objection : 1039 a 14 23, But, instead of modifying his view of the universal 
as M ova-La and therefore posterior, he is content with the remark that an 
objection which, if true without qualification, would make definition impossible, 
must somehow admit of qualification (1039 a 21 sq.). He held that, strictly 
speaking, infimae species were alone capable of definition, because to them 
alone belongs the form or quiddity (1030 a n), which we define (Xyos TTJS 
ova-Las) by collecting the essential, and excluding the accidental, characteristics 
shared by the members of the infima species. Thus we obtain a single 
definition for the entire species : Metaph. 998 b 12. This method of comparing 
individuals and obtaining a KadoXov or common predicate is an aid to defining 
and well adapted to the conditions under which human knowledge is acquired : 
but the community of predication has really nothing to do with ova-La. If the 
species were reduced to a single member, the specific form would continue to- 
be the quiddity of the sole survivor ; whereas the genus, e.g. ova-La 



I. i 402 b 5 187 

aio-07}TtKfi or TO Tpixfj didcrrarovy is but the matter of a definition and requires to 
be informed by a differentia before it can express the quiddity of any actual 
particular: Metaph. 1038 a 5 sqq., 1043 b 30 33, 1045 a 34 SO L- ^ * s because it 
is TO fI8os TO VQV^ &$ 'Idtov vTrdpxov r< ? irpdypaTi, inhering" in the particular and 
informing it, that form or quiddity is defined ; and not because it is shared in 
common by a certain group of particulars. This may be seen if we either 
enlarge or contract the groups (i) by including horse and dog under the logical 
entity quadruped, man and fowl under biped, or (2) by setting up a similar 
logical entity in the artificial groups pointer, pony, albino. When we have 
reached aro/xa TO> ett either from above or below, the end of classification has 
been attained. 

I have assumed that animal, here called TO /ea0oXow, is a genus. We know 
from Metaph. 992 b I2sq. that in some cases it is impossible for the universal 
to be a genus (e.g., the highest universals, / and &/, are not genera in the same 
sense as biological classes : 998 b 22, cf. AnaL Post. II. 7, 92 b 13). Not that 
all the things called 6Wa are homonyms without any link of connexion save 
this common predicate r on the contrary, they are all so called from their 
relation to ova-ia, substance or Being proper, Metaph. 1003 b 5 15. There 
can, however, be no doubt that animal is a true genus and man, horse, dog 
true coordinate species or mutually exclusive classes. Yet animal is the 
example which A. takes when examining the claim of the universal to rank 
as oucrio, Metaph. Z. c. 13, and his emphatic rejection of the claim, io38b 
10 1039 a 2, has been referred to above. 

In this chapter A. simply states his problems without solving them. This 
one is solved in 4i4b 20 sqq., whence it appears that there is a single definition 
of soul, as of rectilinear figure, number and, we may add, of animal or any other 
genus (quadruped, biped, etc.), more general than the infima species. But in all 
these cases the definition obtained by comparison of individuals is imperfect 
and inadequate. It needs to be supplemented by the study of the species. 
I agree with Mr Innes that A. does not base his argument on TO cfagfjs at all 
(CZ Rev. xvi., p. 462) : it would be just as valid if the different types of soul 
were mutually exclusive, like biological classes. In fact, A. studies them as if 
they were mutually exclusive : he treats, not of the soul of the plant, the jelly- 
fish, the non-stationary animal, the rational animal, but of OpcimKov, ala-BijTi^ov^ 



b 5 ir<$Tpov els o Xo*yos...6 tti-nffs lor*. If souls belong in all cases to the

its species, (2) that it does exist, but &s vXrj ; 1038 b 34 1039 a 3, 1039 a 30 b 2

plurality of parts of a single soul, we have to decide whether our study should 
begin with the whole soul or with the parts, and how these parts are severally 
distinct ; whether the study of the parts should be preceded by a study of their 
functions [ 6] ; and, if so, whether we should begin with an examination of 
the objects with which the several faculties and their functions are respectively

ation, it is clear that ai/riKe//zei/oi/=the object of a mental operation, the external 
thing to which we are attending. We shall presently find vnoKel^vov used 
in the same way for the object of perception, e.g. 422 b 32, 426 b 8, 10. Thus 
colour is the " subject-matter," the peculiar province, of sight, sound of hear- 
ing. Plato in the Republic (511 D, E) had described the faculties as set over 
against (eVi) things sensible and things intelligible respectively.

But if it is once settled that the operation of sense-perception (as better 
known) is to be studied before the faculty, if we further determine to study the 
sensible object before the operation, plainly the sensible object will be studied 
before the faculty. And as the ultimate aim is to arrive at knowledge of the 
obscure (part or) faculty, it is natural enough to speak of the study of the 
sensible object as preliminary to this. 

4O52b 16 4O3a 2. It would seem that, while the determination of 
the essence or What is of use, as in geometry, for the study of the essential 
properties which follow from it, at the same time the study of these essential 
properties also materially contributes to the knowledge of what a thing really 
is. In fact, when we are in a position to give an account of all or most of the 
properties as they are confusedly and imperfectly presented to us, we shall best 
be able to define what a thing really is, such a definition forming the starting- 
point of all demonstration. Hence definitions which lead to no information 
about attributes are of use .for dialectical purposes only and have no scientific 
value [ 8]. 

b 16. OIK 8* KT|. This section deals generally with the logic of science 
conceived as an instrument of discovery, in particular with the relative im- 
portance of a study of essence and a study of properties, the two co-ordinate 
parts of the enquiry proposed (402 a 7 sq.). The series of problems (a 23 to 
b 1 6) is nearly complete. Only one remains (403 a 3 sqq.) avroplav 5* l^et /ere. 
They have all been propounded with perfect impartiality, no clue being vouch- 
safed as to a future decision ; but the alternatives presented in the last 
section (b 9 16) suggest the possibility that we may have to proceed indirectly 



I. I 402 b 15 b 21 191 

a posteriori by reasoning from the effect to the cause, and studying the 
properties in order to obtain a definition of the essence. Accordingly A. faces 
this possibility and justifies the procedure in question. The fields of enquiry 
are diverse. Sciences like geometry deduce properties from definitions, else- 
where the study of the properties precedes and contributes to the discovery of 
the definition. In any case, the possibility of deducing properties serves as a 
test of a scientific definition. See note on b 26. Cf. Metaph. 1035 b J 6 cxao-rov

I. 2, 71 b 9 1 6, b3o sq., I. 6, 75 a 31 37, I. 14, 79 a 23 sq. The conclusions of 
a particular science must be demonstrated, i.e. the facts they state must be 
shown to follow from premisses better known and causally connected with the 
first principles of the science (ib. 1.2, 71 b 17 sqq.), the middle term in all such 
syllogisms denoting the cause of the effect stated in the conclusion. Leaving on 
one side such conclusions as are merely accidental and depend upon extraneous 
causes, the rest are the essential properties of the peculiar province (yivos) of 
the given science, and ought therefore to admit of being demonstrated syllo- 
gistically from the first principles of that science upon which remotely or 
proximately they depend.

To sum up. The fundamental meaning in ^avraa-La is presentation to the 
mind, first in the act of perception and afterwards when by the faculty of 
imagination in the technical sense this appearance is recalled and again 
presented to the mind. In modern psychology the distinction between the two- 
is marked by the two terms presentation and representation, and A/s technical 
<pavracria or TO <pavracrTLKov is what would be called a representative faculty, 
though loosely used, as A. includes among its effects the production of the after- 
mage. Etymologically the earlier meaning of <pavraa-ia, as of <f)aiveo-0ai. } is pre- 
sentation or appearance and this, its normal sense in Plato and earlier writers, 
is often retained by A., as here. See further note on 404 a 28.

definition. A. applies this to previous definitions of the soul, 408 a 3 5, 409 b 
14 18 ; cf. Grote, Aristotle, p. 452, 2nd edition (Vol. II. p. 179, ist edition) : 
"Aristotle rejects all the theories proposed by antecedent philosophers... he 
pronounces it incorrect to say that the soul is moved at all. He farther observes- 
that none of the philosophers have kept in view either the full meaning or all 
the varieties of soul : and that none of these defective theories suffices for the 
purpose that every good and sufficient theory ought to serve, viz. not merely to- 
define the essence of the soul, but also to define it in such a manner that the 
concomitant functions and affections of the soul shall all be deducible from it."

4O3 a 3 1O. As regards the attributes or affections of the soul, there is 
the important and difficult problem, whether they are all shared with the body 
or whether the soul has any affection peculiar to itself. The dependence of the 
soul upon the body is apparent in most of its functions, whether active or 
passive, e.g. in anger, desire, sensation. Thinking would seem to form an 
exception, though if it be a species of imagination, or not independent of 
imagination, even thought would be dependent upon the body [ 9]. 

a 3. cxiropfav 8 s <?x l - The remainder of this chapter is devoted to the last 
problem, viz., Are there any properties of soul which are independent of body ? 
Its discussion leads to a digression on the subject-matter of various branches of 
science, from which A. returns in the concluding sentence, b 16 19. 7r6rep6v 
,..4 KOLVO. This is best understood if we revert to 402 a 9 sq., where the 'dis- 
tinction drawn must be the same, though the order of the alternatives is 
reversed. Consequently the attributes or properties here said to be shared by 
the possessor of the soul are those referred to in the earlier passage as belong- 
ing to the animal in virtue of the soul (St* CKCIVIJV'), i.e. belonging to the animal 
as a whole because it is animate (ep^v^ov}. Such attributes or properties are 
distinguished from those that are peculiar to the soul itself and not shared 
by the body which it animates. As in Metaph. 1038 b 10 sqq., t'&ov o oi>x

In Plato, e.g. Tim. 69 D, 77 B (cf. 42 A), there is an attempt to distinguish 
two uses of the word aLcrdrjo-is^ which In Greek had to do duty for the feeling of 
pleasure or pain as well as for the cognitive element of sensation proper. As 
Professor Beare points out (Greek Theories of Elementary Cognition, pp. 270, 
n. 3, 273, n. 3) there was an analogous double use of the English word 'feeling.' 
In psychological works of the last century feeling had to do duty for the sense of 
pleasure and pain as well as for the factor of cognition. oXcos (jnd. Ar. 505 b 47)

The optative with av expresses the logical consequence, as often, e.g.

4O3 a 1O 27. This involves the further question of the soul's separate 
existence. If there is any activity or affection of the soul in which, the body 
does not share, its separate existence will be possible : if not, it will not be 
separable from the body. In the latter case its mode of existence is comparable 
to that of the straight line, which has many properties, qu& straight, but is never 
found apart from something corporeal on which its existence depends. Ex- 
perience confirms the view that most attributes of the soul are similarly 
dependent upon the body, as the necessary condition of their existence, and 
this is shown quite clearly by such emotions as anger or fear. It follows 
from this that they are forms or notions immersed in matter, i.e. the matter is 
a necessary condition of their essence, and this dependence upon matter is seen 
when they come to be defined [ 10],

(Hermes vil. p. 416 sqq.) objects as not justified by the language, and incon- 
sistent with the purpose for which the illustration is introduced. As to the 
language : " Soil <-\>6v in dem Dativ r<5 evQei eine andere Bedeutung haben, als 
in dem bestimmenden Zusatze fj evtiv, so scheint es ein imerlassliches Erforderniss 
zu sein, dass zu evSei noch ein bestimmendes Wort gesetzt sei, aus dem dieser

einen solchen Zusatz hiesse es doch mehr als billig ist von dem Leser bean- 
spruchen, wenn er auf clen blossen Anlass des jj unter dem Worte *v0v in dieser 
Verbindung verschiedene Begriffe denken soil." This is a strong argument, but 
not absolutely convincing. Philoponus is right in saying (49, 18 sq.) that r<i> 
etj0i is ambiguous, and Torstrik satisfied himself that the words might mean not 
only (i) abstractam recti notionem, ro ri rjv elvcu, definitionem recti or (2) lineam 
rectam. mathematicam, rectum mathematicum quod mathematico corpori insit, 
but also (3) in materia sensili rectum expressum. Further, the mention of the 
brazen sphere is confusing. But when we turn to the purpose of the illustration 
all ambiguity is cleared away. If for the illustrative example we substitute the 
proposition which it is introduced to suggest, we shall have to write with

and adds "rovro enim rem sensilem quasi digito monstrat." But the usual 
Aristotelian pronoun for a concrete thing is o&?, not o&ro*, and even then some 
addition is required as in ode 6 av9pa>7ro$, roSe TL. On the other hand ovr<&, if 
taken with a^erat and as = fcara oriyf^v, gives the following sense ; the abstract 
straight line will not touch the brazen sphere at a point, for it has no separate 
existence. The properties of soul may be illustrated by the properties of a 
straight line, one of them being contact with a sphere at a point. To this will 
correspond some active or passive function of soul (e.g. ata-Qrjcris). But just as 
contact implies concrete bodies, so that the straight line in abstracto will only 
have this property as long as it is embodied in something concrete, so the soul 
will cease to exercise its active or passive functions when separated from the 
body. As a matter of fact, the straight line in abstracto has no separate 
existence apart from the particular concrete things which are straight, Philop, 
50, 3 eVcl fjLT)8e v<l>(rrr}K, and, in the hypothetical case we are considering, the 
soul will be like it in this respect. That the comparison of soul to the mathe- 
matical straight line is introduced for a special purpose in working out one of 
the two alternatives suggested by the problem we are considering is clear from

generally (402 a 8 note) and not restricted to specific emotions (animi pertur- 
bation es, afTectus, afFectiones) as defined and enumerated by Aristotle, Eth. 
Nic. 1105 b 20 sqq., and described in detail, Rhet. n. cc. 2 n. That the 
word has the wider sense in 403 a 3 sqq. is plain from the mention of ala-6dvecr6at> 
and i/o<-tv (cf. Traor^etj/ ovde TTOLCLV a 6 sq.), and to restrict it now would be fatal 
to the argument. A.'s object in what follows is to prove that every mental 
operation has its bodily concomitant As many of the bodily changes are 
internal and unperceived, he argues indirectly (<rr]p.lov fie a 19) from the 
difference of temperament in man and man. This difference of temperament 
cannot be due to the object, i.e. the external causes (iraQripdrtov a 20) which 
tend to excite emotion, for in that case the same slight would rouse all 
men alike to anger, the same terrors would excite fear in all alike, whereas it 
is notorious that the choleric temper is prone to anger on trivial occasions and 
the melancholic temper so timid that it gives way to groundless alarms, these 
differences between man and man being due to the bodily constitution. Thus 
anger cannot take place without the body, without a concomitant affection of a 
definite part of the body, and this bodily affection cannot take place without the 
soul, for the body in which it takes place is at all events animate : ro Zpyov ovx 
virdpxet, civev alo-Qffo-e&s. What is said of anger and fear must be understood to 
apply to all the mental functions. A. chose the emotions to illustrate the wider 
sense of operations or attributes simply because the dependence on the body, 
though nowhere perfectly clear, is more obvious in their case. The analogous 
argument from the dependence of sensation upon sense-organs will be found 
408 b 20 sqq.

with them, i.e., whenever there is a mental affection, a bodily affection accom- 
panies it. The mental and the bodily processes go together. The bodily 
change may, however, be internal and not capable of direct verification ; hence 
A. resorts to the argument from signs.

the etymological connexion of opyL^ecrQaL with opyav seems plain from the 
context. But the subject to opyifrrai must be personal. This is one of many 
instances of subject omitted. The subject omitted can generally be supplied

a 26. otov TO ^p-y^eo-eai. In the Rhetoric 1378 a 31 sqq. anger is defined as a 
painful desire (opegis) of apparent vengeance, on account of an apparent slight 
done to one's self or one's friends, when the slight is unjustifiable. This definition, 
which leaves out the physical aspect, is represented in a condensed form by opegis 
avTiKwrrrjo-ecos below. KVT]OTLS. This word covers at once physical movement 
and psychical change. And thus the definition which it introduces includes in 
brief both types of definition, the physicist's and the dialectician's, which are 
distinguished below. <re6|j.ttTos tj p^povs t] 8wc|X<D$. By thus adding " or of a 
part or of the faculty belonging to it" Aristotle is providing for those cases 
where the mental process is thought not to affect the body as a whole, but to 
be confined to some particular organ, as seeing to the eye. Such an organ 
operates or functions in virtue of the faculty which resides in it and constitutes 
it an organ or instrument : the organ implies the faculty, the eye vision, as will

-4O3 a 2 7 b 1 9. A digression upon the relation of psychology to physics 
or the science of nature. To study the soul as thus dependent upon the body falls, 
then, to the natural philosopher. The emotions would be differently defined 
by the mere dialectician and the mere biologist: e.g. anger to the one 
is a desire of revenge, to the other a ferment of blood about the heart, or the 
like ; just as a house may be defined, on the one hand, by its end, protection 
from the weather, on the other hand, by the particular materials, the stones, 
bricks and timber, of which it is composed. A complete definition, whether of 
anger or of house, must include both end and materials ; it must take account 
of the form as well as of the matter : and such a complete definition alone 
satisfies the requirements of physics, the true science of nature. But what of 
the two incomplete definitions, viz. that which takes account of the form, 
neglecting the matter, and that which deals with the matter to the exclusion 
of the form? The truth is that the properties of things are forms which fall 
for investigation under different branches of science according to the varying 
degrees in which they are implicated in matter. There is no science that investi- 
gates the properties of matter which are not separable, nor even regarded as 
separable, from matter. Physics treats of all the properties of such and such 
bodies and of such and such matter, viz. of natural bodies capable of motion, and 
of sensible matter. When the properties of bodies are not thus regarded, they 
lie outside of physics and in some cases fall within the province of the arts and 
crafts. Properties of bodies which, though really inseparable, are for scientific 
purposes treated as separable, i.e. as not bound up with the particular bodies to 
which they belong, fall under mathematics, while, if they are regarded as 
wholly separate from body and from matter, they fall under First Philosophy 
or metaphysics. 

To return from this digression. As we were saying, the affections or 
properties of the soul, in so far as, like anger or fear, they are implicated in 
matter, are inseparable from the physical matter of the animal, while at the same 
time, unlike the mathematical properties of bodies, they cannot be abstracted 
and treated as separable in thought [ n], 

a 27. Sid Tavra TJ8t|, i.e. because the emotions are "implicit in matter," 
because they imply bodily movement, or at least modification (oXXoiWc?) of a 
faculty of an animal. No sooner is this recognised than an inference can at once

The definition of the physicist will be scientific ; that cited above from the 
Rhetoric is dialectical, for rhetoric and practical philosophy generally, owing 
to the nature of their subject-matter (viz. what is contingent and only generally, 
not universally true), are content with something less than the accuracy (a*cpt/3eta) 
of theoretical science. Maier, l.c* II. b, p. 61, remarks that, by this contrast, we 
are reminded of Plato's diaXeKrixo?, who is the true philosopher.

agreeing with Trend. "ctdo?...et facilius est et rei aptius," I suspect the word

even if cidos had the strongest evidence, the sentence would still be a truism, 
which there seems no sufficient reason for repeating when it has just been 
assumed in the preceding sentence. The great majority of our MSS. read ode 
or 6 dc, and this is confirmed by Simpl. and Philop. Obviously the uncial OAE 
is the common source, and this might be read oSe, as W. and possibly Them., 
or divisim Q SV, as Simpl. Plutarchus Atheniensis apud Simpl. and Philop. took 
it to be. Simpl. 21, 35 OVK &s 6 cj>i\6a-off)0f el-yye'irat TL\ovTap^of, dvrt8iaip>v rov

this back from oblique to direct we get the text of SimpL, viz. o de \6yos rov

the word after rovretm. It would seem, then, that Plutarch, like Philoponus, 
explained "The one definition is the form, the other belongs to the thing," 
i.e. not to the form, for Plutarch made the two clauses stand opposed. Simpl.,

(b 2) TO Ldof KOL TOV \6yov. Whence did Them, get opegis avTt\virr)<ra>$ in his first

tion) is the notion of the thing," i.e. of anger, ode being attracted to the 
gender of Xd-yo?. This gives a satisfactory sense and avoids tautology. 
If we accept tl&os, the lectio facilior, the question arises, why should A. 
reiterate the identity of \6yos and eldos which he had assumed already (403 a 25 
Xdyot evv\oi 9 b 2 TO etdoff ical TOV \6yov) ? A. may have done so, being on occasion 
as pleonastic as he is elsewhere elliptical, but, if so, the text of all the Greek 
commentators was faulty in this place. Did A. write simply 6 fj.ev yap \6yos TOV

preceding is, I think, misunderstood by Them. (8, 4 6 H., 14, 4 6 Sp.), SimpL 
(22, 27 29), Trend, (p. 174), who interpret as if A.'s meaning were "no one, 
except the physicist, treats of the inseparable properties belonging to natural 
bodies and to sensible matter and treats them as inseparable : quae a materia 
separari non possunt (ra ^ ^copio-ra, Metaph. 1026 a 19, 25 sqq.) ea sunt ipsa

kind and of the matter implied therein. Physics treats of bodies regarded as 
in motion or capable of motion : in order that they may be in this sense <uo-iAca 
crcbjuara they must have a certain kind of matter, viz. the matter conditioned by 
this requirement. Cf. Metaph. 1077 b 22 24, 30 32 ; Phys. II. 2, 193 b 35 
194 a 15, 194 b 7 9, 9 13. It is owing to the contingent character of their 
matter that, strictly speaking, neither definition nor demonstration is applicable 
to particular physical substances: Metaph. 1039 b 27 31, 1036 a 2 9. The 
terms <pv<riKov a&aa, <ucmc?7 v\rj (412 a 12, 403 b 17) convey no information, 
when the province of physics is what we are defining. All natural bodies can 
be described by such attributes as Kiz/T/roV, al<r0T]T6v, V\IKOV (cf. Bonitz ad 
Metaph. 1026 a 3). If any single adjective could replace TOLCLVTTJS it would be 
KLvrjTtjs. Cf. Metaph. 1069 a 36 sq., 1036 a 10, 1026 a 12, 1026 a 2 sq. It must 
be wider than ycwrjrrjs KOI <p&aprfjs, Metaph. 1042 b 5 sq., cf. 1069 b 25 sq. 
All natural bodies are self-moved or have in them an inherent principle of 
motion and rest (De A. 412 b 16 sq., Metaph. 1025 b 20 sq.) ; this serves to dis- 
tinguish them from the products of art. From the objects of mathematics, again, 
they can be distinguished, in that, whereas the latter, e.g. the circle or the line, 
can be defined apart from the particular matter in which they are found, natural 
bodies are concrete of form and matter and incapable of definition apart from 
the particular matter belonging to them. A.'s favourite phrase for such a con- 
crete thing is robe ev r<Se, the particular form residing in particular matter, 
cf. 429 b 13 fj yap crap OVK avev TTJS vX^s-, aXX* &<rirp rb o-ipov, roSe ev r<5e.

There seems no reason why nadav should not be understood. It is quite true 
that the physician is concerned with the individual patient (Metaph. 981 a 15 
24), but it is also true that health and disease are accidents, not essential 
properties, of a natural body, and the physician studies them solely in order 
that he may substitute health for disease. Hence in his case rtvj/=such as can 
be produced by i/oOr, Tcxvrj or dvvafus and not, unless it be diro rauro/idrov, by 
matter left to itself (Metapk. 1032 b 21 26). Similarly with the carpenter, but 
the properties which he seeks to impart to his materials are even more plainly 
adventitious and artificial, such as could not have been even spontaneously 
produced. Cf. Metaph. Z., c. 9 throughout, also c. 7, especially 1032 a 32 b26,

CHAPTER II. 

The first chapter has introduced to our notice in a somewhat tentative and 
summary fashion the problems and the method of psychology as conceived by 
A. Before going on to his own exposition, he devotes the remainder of the first 
book to a review and criticism of the received opinions on the subject. Such a 
critical review forms a part of many Aristotelian treatises, the best known 
instances being the first book of the Metaphysics and the second book of the 
Politics, and is often of the highest value alike for the information given as to 
the views of other philosophers and for the insight thus afforded into the founda- 
tions of his own constructive theory and the interdependence of its parts. In a 
subject so obscure and difficult as the present it is not to be expected that much 
can be gathered from the general body of current opinions usually designated 
i/doa, to which he frequently appeals in a popular treatise like the Nicomachean 
Ethics (403 b 25 sq., 29 sq., 404 b 17, 28, 405 a 28, b25, 26 sqq.). Even cita- 
tions from the poets and remarks of men eminent in other departments of life 
yield very little (404 a 29 sq., 410 b 27 sq,, 411 a 8). The opinions stated and 
criticised belong almost without exception to the philosophic schools of his 
predecessors. The great physicists of the fifth century Democritus, Empe- 
docles, Anaxagoras, on the one hand, and on the other Platonism as presented 
in the Timaeus, and again as taught by A.'s own fellow-pupil and personal 
friend Xenocrates in the contemporary Academy, receive the fullest treatment, 
while the theory of harmony, familiar to us from the pages of the Phaedo^ a 
theory which at first sight bears a remarkable likeness to that of the ente- 
lechy, is also singled out for discussion and refutation (407 b 27 sqq.). Slight 
.attention is bestowed upon other thinkers: certain Pythagoreans (404 a 18), 
Thales (405 a 19), Diogenes of Apollonia (405 a 21), Heraclitus (405 a 25), 
Alcmaeon (405 a 29), Hippon (405 b 2), Kritias (405 b 6) : but their contribu- 
tions are obviously regarded as unimportant by comparison, and even the claim 
of Alcmaeon, Hippon, and Critias to rank as philosophers is doubtful.

210 NOTES 1.2 

A. makes some attempt to classify the divergent theories before him (403 b 
25 sqq., 405 b ii, 409 b 19). Starting with the common opinion that both the 
motion and the perception of living creatures are due to soul, the various 
theories may roughly be classified according as they emphasise the one or the 
other of these functions. In the former case, soul is described as the most 
mobile of things, as by the Atomists, who identified it with heat, both fire and 
soul owing their mobility to the small size and spherical shape of their com- 
ponent atoms. If, however, perception and knowledge be taken as the pre- 
eminent functions of soul, and if it be further admitted that like knows like, it 
follows that soul is a compound of the elements which go to make the world. 
Under these two heads (i) the most mobile substance and (2) the primary 
element or (if there be more than one such) a compound of the primary elements, 
there is room for a wide diversity of opinions, for the most mobile substance 
may be taken to be material, e.g. fire, or immaterial, e.g. a self-moving number, 
whilst both the number and nature of the primary element or elements has been 
notoriously open to discussion. There is no general agreement whether they 
are one or many, corporeal or incorporeal. Sometimes the two views 'are com- 
bined. Sometimes the substance declared to be soul would seem to have been 
selected because of the fineness of its particles, so that, if not indeed actually 
incorporeal, it would appear such in comparison with grosser matter. Hence 
we have another head (3) the incorporeal, and virtually incorporeal. As a 
general rule, there is a close affinity between the views of various philosophers 
regarding the elements of the universe and the composition of the soul. In this 
respect, however, Anaxagoras forms a notable exception. 

In c. 2 A.'s attitude is for the most part expository, except that in 405 b 19 
23 an objection is raised to the theory of Anaxagoras. The fact is that he is in 
partial sympathy with the views expressed under each of the three main heads 
under which he arranges his predecessors. He holds that soul is (i) KLV^TKOV^ 
(2) yvwpicrriKov, and (3) ao-oytaroi/. His quarrel is with the one-sided way in 
which these various characteristics of soul have been presented and with the 
inadequacy of all the formulae hitherto devised for their expression. Thus as 
regards (i) he agrees that soul is KLV^TLKOV but denies that it is Kivovpevov (see 
c. 3) ; as regards (2) he combats the inference that, because soul is that which 
knows, it must therefore be compounded of the elements of the things which it 
knows (see 409 b 19 sqq.). Similarly the theories which at first sight would 
seem to make the soul incorporeal are found upon examination (see I., c. 4) to be 
vague or inconclusive. For contributions to a better understanding of A.'s own 
positive view we may refer to other later criticisms, e.g. 407 b 1 3, 408 a 34 b 29,, 
411 a 24 sqq. 

4O3"b 22O 4O4b 8. Introduction to the critical review of previous 
opinions on the subject. Motion and perception, the primary characteristics of 
living things, have been taken to be the primary characteristics of soul, and 
motion has been taken to imply mobility ( i 2) e.g. by Democritus and 
Leucippus ( 3), by certain Pythagoreans ( 4), and by Anaxagoras. But there is- 
a difference between Democritus and Anaxagoras. The former identifies intelli- 
gence with life, vovs with fax*!* th e latter is not so clear. He appears some- 
times to distinguish them, as when he makes intelligence the final cause of 
the universe, sometimes to confound them, as when he attributes intelligence 
to even the humblest of living things ( 5). 

The important part which the conception of motion played in all previous 
speculation is fully recognised by A. Among other passages we may refer to- 
Phys. VIII. 9, 265 b 17 266 a 5. There he starts with the remark that all who- 



I. 2 403 b 20 b 25 2ii 

have treated of motion (KLVTJ<TLS} agree in considering spatial motion, <popd, as the 
primary motion. Their first principles are causes of spatial motion. This is 
exemplified by those who explained qualitative change by means of combination 
and separation (probably the lonians), by Empedocles, whose Love and Strife 
bring about motion in space, and by Anaxagoras and by the Atomists. The 
other kinds of change (Kivrjcris) they attribute not to the primary elements or 
principles of things, but to the compounds to which they give rise. So, too, 
with those who introduce condensation and rarefaction to explain change.

complete enumeration of difficulties is an indispensable preliminary to their 
solution. The implication is, not only must we state the problems but we must 
also take into consideration the attempts of our predecessors to solve them. 
The problems have been stated 402 a 23 sqq- The review of previous opinions 
g-oes on to the end of the book. In the Metaphysics, the first book contains the 
review of previous speculation, while a comprehensive statement of diropiai

A. is our oldest and most credible authority for this as for most of the opinions 
of the Atomists. The more precise definition of later writers (see Diels, 
Doxographi Graeci^ p. 388) is derived ultimately from A. J s pupil Theophrastus. 
Observe that there are two statements here : (#) that Democritus identified soul 
.with fire or warmth,. () that his reason for doing so was the mobility of the

a 3. olov KTC. So far we have had a clear statement, which is resumed at 
404 a 5 rovrcov 8e TO. cr<f>cupocidTJ TJruxn v : where the reason why spherical atoms 
were selected is given. But the interspersed simile of the motes in the sunbeams, 
as well as the more general reference to atomism as contained in the words <Jz/ 
7-37^ fjLev iravcTTrepfJLiav rrjs oXy? (frvcre&s errot^eTa Aeyet* dfjLoicas de KCU A-evKirnrof, 
tend rather to confuse the exposition ; probably " soul-atoms," and not atoms in 
general, are compared to motes in the sunbeam : and, if we lay unusual stress on 
<acVerat, the point of comparison may be, as Them. (9, 13 19 H., 16, 12 20 
Sp.) says, that soul, though invisible, may be corporeal, as are the motes which, 
ordinarily invisible, are seen in the sunlight under certain conditions. With 
this Simpl. 25, 30 26, i and Philop. 67, 21 28 in the main agree, though 
they lay more stress upon the minuteness than upon the invisibility of the 
atoms. But the atoms are wholly imperceptible to sense ; they are not, like the 
motes, though usually invisible, visible under exceptional circumstances. The 
point of the comparison between motes and atoms must be the incessant 
mobility (a 20) and endless multitude of the motes : in Milton's words " Shapes 
...as thick and numberless as the gay motes that people the sunbeams." The 
fact which Them, advances, their partial and occasional visibility, really makes 
against them as suitable illustrations of the invisible atoms. Lucretius u. 1 14 
141 uses the simile of the motes to illustrate the incessant motion, not of soul- 
atoms but of atoms in general : conicere ut possis ex hoc, primordia rerum | 
quale sit in magno iactari semper inani (121 sq.). We see, he says, the motes, 
impelled by unseen blows, change their course and tumble restlessly, now in 
one direction, now in another, and we must infer that this restlessness and 
change of direction are due to unseen movements of the atoms. For the atoms 
move first of themselves ; next those bodies which form a small aggregate are 
impelled and set in movement by the unseen strokes of the atoms, and they next 
in turn stir up bodies which are a little larger, till by little and little they become 
visible and are seen to move in the sun, though why they move is not seen.

only reality, for which sttfrag: n ap, Sext. Emp. vn. 139. Zeller continues: 
" If, therefore, Aristotle attributes to Democritus the opinion that the sensible 
perception as such is true, the statement is founded merely on his own 
inferences ; because the Atomistic philosophei- did not definitely distinguish 
between the faculty of perception and that of thought, therefore Aristotle 
concludes that he must have put both on the same footing in respect of their 
truth." Cf. Natorp, Erkenntnissproblem^ p. i64sqq. The passage I have above 
cited from Metaph. 1009 b i 17 is part of A.'s defence of the law of contradiction, 
that a thing cannot be at the same time and in the same respect both A and 
not-A, which we are justified in asserting D. held as firmly as A. himself. 
Cf. further 426 a 20 sqq. Dyroff, however (Demokrit-Studien^ pp. 74, 88), 
inclines to think that D. himself and not A. drew this inference. Dyroff 
thinks A. is right in holding that because ala-Odvt-a-Oai, = voelv and sense- 
perception is an aXXotWis (ioo9b 13: Zeller and Natorp overlook this), there- 
fore that which appears by means of sense-perception is true. Instead of 
"thought and perception both depend upon body" D. said "thought is 
perception, both are corporeal," and this, Dyroff thinks, justifies the conclusion, 



I. 2 404 a 28 b i 219 

even if A. drew it. Whether D. did, or did not, deny objective existence 
altogether, his position as regards the sensible qualities of matter is clear. 
He was the first to lay down the distinction between the so-called "primary" 
and "secondary" qualities. The atoms have no secondary qualities. Thus 
colours, flavours, smells per se have no objective existence : they, at all events, 
are subjective affections of the percipient. Colour belongs not to the atoms, 
but to the natural objects which are produced by the aggregation of atoms, and 
is due to the order, shape and position of the atoms in such aggregates, whereby 
they act upon our sense and qualitatively alter it. Cf. Theoph. De Sensibus 63

&aA//-evdeo-0<u. That neither 0/jovetv nor uoeTv can be identified with 
ala-Bdvea-dai is argued succinctly 427 b 6 14. Democritus (and Leucippus, if 
the work Hepl vov is rightly ascribed to him) has not so differentiated the term, 
but employs it in the older and vaguer sense for soul in general as the 
animating principle or part. This is the usual meaning of voos in Homer and 
the older poets (eVt o^rfjBecro-iv drdpftrjTos v6os ccrr/i/, evfj.vei voop) frequent in 
Hdt., e.g. VIIL 97 C'K TTCLVTOS voov, and at all periods in the phrase icara voi/.

4O4 b 8 4O5 b 1O. The other view, which regards soul as that which 
perceives and knows, identifies soul with the constituent elements of things 
perceived or known (i.e. of the universe), because like is known by like. Thus ' 
Empedocles ( 6), Plato in the Timaeus, in Ta irepl <tXoo-o<taff and elsewhere ' 
( ?) Others [i.e. Xenocrates], combining motion and perception, have defined * 
the soul as a self-moving number ( 8). We have thus classed together 
philosophers whose views as to the nature and number of the constituent 
elements of things are widely different, some considering them as corporeal, 



I. 2 404 b I b 12 221 

others as incorporeal ( 9), some admitting but one ultimate principle, others 
a plurality. But the view taken of the soul and the view taken of the universe 
will be found to agree ( 10). This agreement is exemplified in Democritus 
( n, 12). The views of Anaxagoras ( 13), Thales ( 14), Diogenes of 
Apollonia ( 15), Heraclitus ( 16), Alcmaeon ( 17), Hippon ( 18), Critias 
( 19) are briefly stated.

By ra a-TOLx^a travra are meant the four so-called elements or o-afiara air\a of A., 
earth, water, air ( = al0f)p of Empedocles), and fire, as well as the two moving 
forces, attraction and repulsion, personified as Love and Strife. As Zeller shows 
(Pre-Socratics, Eng. Tr. IT. pp. 167 sqq.) this is A-'s inference and involves a mis- 
conception : " A. concludes in his usual manner that according to Empedocles 
the soul is composed of all the four elements, an assertion which is then 
repeated by his commentators. It is, however, incorrect. Empedocles did not 
hold that the soul is composed of the elements : but what we call the activity of 
the soul he explained by the elementary composition of the body ; a soul 
distinct from the body he did not assume. Thought, like all other vital 
activities, arises from and depends upon the admixture of substances in the 
body.... It is in the blood especially, because there the elements are most 
completely mingled, that thought and consciousness have their chief seat, and 
particularly in the blood of the heart \Jrag. 105, 3 D]. But other parts of the 
body are not excluded from participation in thought, provided the elementary 
particles are tightly compressed and mixture is homogeneous. If the right 
admixture is limited to certain parts, the result is sense-organs with their special 
endowment." What Empedocles meant is best seen in the case of the special 
senses. As our sense-organs are composed of the very same elements as the 
objects outside the organism, knowledge of these objects is obtained through 
these organs. Thus the fire in the eye enables us to see fire, and so on. 

b 12. ?vai 8fe KaX ^KOOPTOV ^xV TOVTWV. This also is A-'s inference. If 
soul is compounded of the elements and a part of each element enters into its 
composition, then, in virtue of being such part, any one of the elements may be 
said to be a soul. De Gen. et Corr. II. 6, 334 a 9 OTOTTOV e Kal fj -^vx^ I* r&v

would be apparent even if A. had not told us that Plato eschewed the term 
"point" and preferred to speak of " origin of a line, 7 ' apx^j ypapws (Metaph. 
992 a 21), just as modern geometry calls a point the "origin" of coordinates. 
The point, receiving increase, grows or developes into the line, the second stage 
or /z6Ta/3ao-4ff ; from that it passes to the next stage, for a line by its motion 
generates a superficies (409 a 4 sq.) : by the fourth stage it reaches three 
dimensions and is perceptible to sense. Here, as in Tim. 53 c 57 D, Plato 
substitutes a mathematical deduction of body for a physical deduction. The 
world of becoming is a fleeting show, a phantasmagoria : all the reality in 
which it shares is derived from its Trepara, point, line, surface and solid (Metaph. 
1028 b 16 sqq.). By what arguments this conclusion was recommended may 
still be seen in Metaph. 1001 b 26 1002 a 14. Cf. also Metaph. 1089 a 3 1 sqq-

school, it is very hard to determine.

14, where it is implied that in Plato's teaching there was first a period in which 
the ideas were quite distinct from numbers, and later a period in which they 
were presented as virtually numbers. Of this later phase there is apparently no 
trace in the extant dialogues. The subject of clcrl is still ot apiOpoL We might 
paraphrase thus : The numbers were affirmed to be just what the ideas had 
(always) been, and, whereas other philosophers had chosen material principles 
as principles of all existence, Plato made them numbers, only they were not 
ultimate, but were themselves constituted of component elements (oroi^eTa). 
This phase of Platonism, in which the idea is a number and at the same time, 
as an- idea, the cause of being for particulars is attested Metaph. 1090 a 5 etTrsp

Xenocrates, who is the object of the polemic 1090 a 7 15. A. usually mentions 
two arroixfta of idea-numbers. The first is always unity, the second, the prj ev

much-and-little etc. according as magnitude or number is the product. By 
these elements or ultimate causes of the ideas or idea-numbers, however 
designated, we may understand unity and plurality: Metaph. 1001 b 19 aXXa p.rjv

sensible objects, are subdivided into objects of belief (TTLCTTI^ and objects of 
conjecture (elKacria) : where, however, iria-ris and ei/cao-ta seem to be but species 
of 86a. Thus in the Reptiblic at any rate the spheres of opinion (da) and 
sense-perception (aia-Bijcrif) are not regarded as mutually exclusive. When we 
get to the Timaetts we have again, first, a dual division of objects (51 B sqq.)> 
intelligible realities and sensible phenomena, inferred from the irreconcilable 
distinction between vovs and So|a d\rj0r)$. The latter class of objects, sensibles,

similar as Empedocles and Plato. While they agree in reducing the soul to 
elements or principles they are not agreed on the fundamental question what 
these elements or principles are and how many of them must be assumed.

is taken to be the primary characteristic of soul, but quite as much when soul is

elements which is by its nature capable of causing motion, i.e. they too, as well 
as those who explained the soul from cognition, assumed the soul to be the one 
element or one of the elements of things : they selected an element by its nature 
adapted to produce motion, and declared soul to be that element. The elements 
of the early philosophers, their 7rpS>ra or dpxai, corresponded more or less exactly 
to A.'s material cause. But sometimes a distinction was drawn between some 
elements which were inert, and one (or more) which was active and able to 
move the rest. The best commentary is furnished by Metaph. 984 b i where,

An alternative would be to take r&v Trp&r&v as predicate with vTrctXfj^aa-iv, 
by the same construction as that of r&v Ka\>v (402 a i): and so the Greek 
commentators. " They supposed that what in its own nature is capable of 
causing motion is one of the primary causes. 3 ' If the words are so taken, 
then, since they regarded the soul as capable by its own nature of causing 
motion, it follows that the soul is one of the primary causes : Them. (13, 7 H.,

that it is the apx*} which determines what the soul is, and not the soxil which 
determines what the dpxn shall be (405 a 3 eVofteVoos rovroir). This is clear from 
the parallel case of those who explained the soul as cognitive. Quite apart 
from this, the passage cited from Metaph. 984 b i sqq. seems conclusive as 
against such a recognition of the moving principle, at any rate by the earlier 
Ionian philosophers, who nevertheless are subsequently adduced as considering 
soul from the side of motivity, e.g. Thales, Diogenes, Heraclitus. By rS>v TTP&TGW 
we are to understand the first causes (aLrta) or principles (dpxai) or elements 
(<rrot^ia) which the philosophers in question assumed, and these, as we have

power to impart motion implies mobility (cf. 403 b 29) was shared by the 
Atomists (404 a 7 9), so that these two attributes need not be separated : 
but the fineness of the texture or structure of a body has a limit in the 
indivisibility of the atoms of which it is composed. This I take to be the 
point of the words a 10, TOVTO d'...<rcoyudTcDv. Having thus proved (i) A. goes

explanation, nothing being there said of cognition, while both the motive and

mobile qualities of fire and of the soul are there attributed to the minuteness 
and the spherical shape of the atoms of which they are composed. On the 
other hand Them. (13, n sqq. H., 23, 20 sqq. Sp.) and Philop. (84, 10 sqq.) under- 
stand Ko.Tpov to mean simply (i) TO K.IVSIV and (2) TO Kiveio-Qat : and the proof

would, as Torstrik explains, not so well accord with the view expounded 404 a 
IQ 16 : nam id quod constat ex elementis, quodammodo diversum est ab iis : 
elementa enim plura, hoc unum est. At Democritus animam esse voluit potius 
ipsa rudia elementa nullo unitatis vinculo comprehensa. The atoms are now 
designated cr^ara^ above (404 a 2, 7) they were called "shapes" or "figures," and 
below (406 b 20 sq.) they are called " indivisible spheres." 

a ii. \errro|jL6pLav. If this is the genuine reading, we may trace a con- 
nexion with the view of Democritus as reported by Theophrastus De Setisibus 
75 (Diels Doxogr. 521, 24), probably in reference to the fusing of metals, that 
things which are red hot are not so hot as those at a white heat (Qeppbv yhp TO 
X*7rroV), the rapid motion of the finest particles thus generating both white 
colour and intense heat. Philop. 84, 21 85, 16 conjectures that in making 
spherical atoms fu/cpo/zepeo-raras Dem. was guided by the geometrical pro- 
position that of all solids with equal surface the sphere encloses the greatest

chaos Anaxagoras uses the term vovs and not ^X*? ( as to Plato Crat. see note 
on 404 b I supr.\ From Metaph. 984 b 20 22 ol /xei/ ovv OVT&S v-iroKapftavovrcs 
...rots OVO-LV it appears that A. regarded this vov? of Anaxagoras as at once 
a final and a moving cause, though at the same time he complains (985 a 
18 20) of the inadequate use which Anaxagoras made of his principle.

just as TravTos /naXXov is an emphatic paXXov, both expressions being- favourites 
with Attic writers, especially Plato. Themistius, however (13, 16 H., 23, 28 sq. 
Sp.)> "i ves a different turn to the sentences, paraphrasing thus : dpxnv fao-i o~xed6v 
re T>V ovTotv cLirdvTtov. It is quite easy to see how he reached this interpretation. 
If vovs is described by Anaxagoras as " divisible and as ' inhabiting some 
things, 5 i.e. all things which have life," clearly it does not so inhabit all things 
whatever. Thus Them, must have conceived dpxn * n the sense of internal 
principle, ewTrdpxov TL or crro^etoi/. It is most improbable, however, that A. 
intended dpxn to bear this sense, it must mean what it means below a 18, what 
in 404 b 2 is expressed by TO OLTLOV TOV KaX&s KOI op6>, and apx*i standing alone, 
as in a 1 8, would be sufficient to indicate this. In any case /laXtcrra should not 
be separated from TrdVrcov, as if the former word went with rLBcrai in the sense 
of potissinmm and the latter with dpxn- As to aVoWo)?, the variant of 
codd. S y, the testimony of Them, is of little weight, as he is very fond of 
changing iras of the text into oVa?, as anyone may easily verify for himself.

shows that Hippon, like Diogenes of Apollonia, Alcmaeon and Philolaus, was a 
physician as well as a philosopher, and, like Diogenes of Apollonia, an eclectic 
adapting one of the older Ionian theories (this time that of Thales) to the 
newer speculations introduced by Parmenides. From Schol. Ven. ad Aristoph. 
Nub. 96 sqq. we learn that Hippon had been ridiculed in the Havo-n-Tai of 
Cratinus before Aristophanes brought out the Clouds^ so that he must have 
lived in the age of Pericles, and that Cratinus attacked him for his impiety (Schol. 
Clem. Protrept. i. 422, 23 sq. Dind., IV. 103 Klotz), and the epithet fitieos seems to 
have stuck to him (Philop. adhunc loc. 88, 23, Simpl. in Phys. 23, 22, Clem. Alex. 
Protrept. 24, p. 20 P., loann. Diac., Alleg. in Hes. Theog. 116). In Metapk.

4OS b 1 1 3O. Recapitulating, we may reduce all previous views to 
three heads, according as motion, perception or incorporeality is taken for the 
characteristic of soul. Further, the agreement pointed out between the account 
of the soul given by the several philosophers and their theory of the universe is 
confirmed with modifications in detail. When the soul is defined by perception 
and knowledge, this agreement rests on the assumption that like is known by 
like ( 20, 21, 23). But here Anaxagoras is an exception, for his principle, intel-

ligence, is affirmed to be impossible, and to have nothing in common with 
the other elements of the universe ( 22).

take a)? d-rceiv with Travres. A. goes to great lengths with hyperbaton, and 
irdvres is again separated from cos ei7r*iz/ by three words, 408 a I. It would 
indeed be possible to take obs- d-ireiv with Tpio-Lv. So Philop. 90, 20 sqq. Of, 
crxedbv dvo, 403 b 28. But A.'s fondness for constructions of the type iravr^s^ 
ol fMv...ol de... makes the former view more probable. In any case it comes 
to this, that, since no definition falls outside of the three characteristics (cf. 
Metaph. 988 a 20 23, 993 a n 15), all are based upon one or more of 
them. To 6pLovTcu, corresponds the use of opos in 404 a 9. This triple division 
is repeated 409 b 19 sqq., and seems there to be finally adopted as more precise 
than the twofold division at the opening of the chapter 403 b 25 sqq. The 
present statement must be carefully compared with both the passages referred 
to, to avoid misconception of the meaning. In 409 b 20 we have, not Kivrjcrei,

their immaterial dpxoi (cf. 404 b 29 405 a 4), is proved to bear the elastic 
and relative meaning pointed out in the notes on 405 a 6 and 405 a 27,

The classification is accommodated to the general theories of TO. ovra and 
their ap^al held by A.'s predecessors and reviewed in Metaph.) but even so 
the choice of the term dcrw/zarov is unfortunate when we find A. there com- 
plaining that some of these theories have taken no account of do-oo/iara proper 
(e.g. Metaph. 988 b 24, T&V yap o-wpdT&v TO, oro^Za rtBeatrt /j,6vov y T$>V d*

It may be asked, why 7rdvTcs...a>$ etTrelv ? Either this is one of the cautious 
expressions with which A. habitually guards himself when making a sweeping 
statement (cf. 403 b 28 ax^ov vo) : or else he may have in view the theory 
of frppovia, since in one of the two forms to which he reduces it in I., c. 4 that 
theory cannot easily be made to square with any of his three divisions.

connexion is most obvious in the theories which start from alcrtirjo-i? and declare 
soul to be ro yvapio-TiKov : 404 b 8 sqq., 404 b 30405 a 7. But A. now 
proceeds to show in detail that it can also be traced in the other theories, so 
far at least as concerns the number and nature of the dpxai assumed (404

b 13. TJ orroixetov f\ IK TWV oTOLxe&ov irotovori, sc. TTJV tyvxyV' The inference

for nature, explained cognition by making the soul consist of this o-rot^Ioi/- 
Anaxagoras (see next note and that on 405 b 19) is reckoned with this group be- 
cause, as was explained 405 a 17, he assigns to his principle Nos both functions, 
TO re yivdxTKeiv KCU TO Kivelv. Empedocles and Critias, on the other hand, 
and, in a very different region, Plato assume a plurality of elements for the 
universe and derive the soul, which is a compound, from these same elements.

case of activity and passivity in general, the corporeal ala-BrjTQv acting upon 
the equally corporeal ala-6a.vop.evov or alo-tirjTiKov which in turn 7racrx WTTQ 
rov ironjriKov. Accordingly in his fuller discussion of alcrdyo-Ls (417 a i) A. 
refers us to De Gen. et Corr. I. 7, 323 b i sqq. (see the citation in note 
on 410 a 23) where we find a similar conflict of opinion on the general 
question. A. concludes that two bodies capable of mutual interaction must 
be evavrta in his sense of the term, i.e. members of the same genus, but 
belonging to different species of it, so that something may be said for 
each of the two conflicting views. Cf. De A. 416 b 6 9. In the special 
application to perception and cognition Anaxagoras consistently adhered 
to the first of the two views set forth in De Gen. et Corr. I. 7, Theophr. De 
Sensibits 27 'Avagayopas 8e yiv<r6a.i [int. rfjv aio-drja-Lv] rots evavriois' TO yap 
ofjLoiov airaOts VTTO TOV opoLov. The inconsistency of those who, like Empedocles, 
supported this view as a physical doctrine, but deserted it when they treated 
of sensation and cognition, is urged 410 a 23 sqq. If Anaxagoras was the only 
exception, it would seem that A. did not share the doubt of Theophrastus 
about Democritus, De Sens. 49 : cf. the admission of Theophr. 50 ra yhp 
6p6<f>v\a K.a<rrov yveoptfav. In fact, since to the Atomists all sensory processes 
were physical processes and all the senses modes of touching or physical 
contact (De Sensu 4, 442 a 29), and since, further, all matter was homo- 
geneous, there is no room to doubt that Democritus carried out the principle 
"like is known by like" more consistently than any other of the earlier 
physicists. 

b 15. 4>a<rl Yap...T<? ojioOp. The explicit statement can hardly be substan- 
tiated beyond Empedocles as cited above 404 b 13 15. A. and Theophrastus 
are however right in declaring that some such assumption was made by most 
of the natural philosophers who attempted an explanation of cognition starting 
usually with sense-perception. Theophrastus confesses that it was originally 
not so much a philosophic principle as a maxim or saw derived from observa- 
tion and experience, much like the proverbs: "Birds of a feather," "noscitur

CHAPTER III. 

This chapter begins with a criticism of soul as a thing in motion 
or capable of motion. With the early philosophers, as we have seen in the 
last chapter, this conception of soul is a necessary inference from the belief 
that soul is the cause of animal motion (403 b 28 31). A., too, shares 
the current belief that soul is Kivr)Tt,Kov or TO KWOVV, but he disproves in a 
series of nine arguments the necessity of the inference that it must be 
TG>V Kivovpewv TI. There follows a critical examination of the theory of soul 
laid down in the Timaeus, 1121 (406 b 26 407 b n). The chapter 
closes with some suggestive remarks on the futility of defining soul without 
taking account of the body to which it belongs ( 22, 23, 407 b 12 26). 

405 b 31 4O6 a 4. Our first subject of enquiry is motion. The 
definition of the soul as that which moves itself, or that which is capable 
of self-motion, is false. It has been already stated that the moving cause is 
not necessarily itself in motion. Against the proposition that soul is moved 
the following objections may be urged (which equally apply to the definition 
of soul as that which moves, or is capable of moving, itself). 

406 a 412. When anything is said to be in motion this means 
either that the thing moved has a derivative and adventitious motion, or that it 
has an independent motion in and by itself. [The ship moves in the latter way 
in and by itself, the passengers conveyed by it in the former, through being in 
something which is itself in motion, as appears from the fact that they do not, 
in the case supposed, employ their own proper mode of progression with their 
feet.] In accordance with this distinction we proceed to enquire whether the 
soul has an independent motion in and by itself, 

4O6 a 12 16. (i) Understanding KIVOV/JLCVOV to mean Ka&* avro 
Kivovpevovy and assuming the four species of motion to be qualitative change 
(dXXoiWir), growth (a%grio-i$\ decay (<0tW), spatial motion (<opa), we affirm 
that, if the soul is moved na6* avro, it is moved naturally, <^v<r, and if it is 
moved with any of these species of motion the soul must be in space, V TOTT^. 

4O6 a 16 22. (2) Further, on the same presuppositions, if it is 
the nature of soul to move itself, there will be a locality in the universe 
towards which as a <j>vo~ci KLVOV^VOV it tends to move [but there is none such]. 



I. 3 405 b 28 239 

4O6 a 22 27. (3) If the soul is moved naturally, it is also moved by 
constraint, but of such constrained motions it is impossible to form any idea. 

4O6 a 27 3O. (4) According to the doctrine of De Caelo, that the 
nature of which is to be moved upwards is fire, as earth is that the nature 
of which is to be moved downwards. Consequently the soul must be either 
fire or earth, according as one or other of these rectilinear motions is attributed 
to it as its essential nature. 

4O6 a 3O b 5. (5) It is a fact that soul sets body in motion, and 
it may be reasonably supposed that the motions produced in the body are those 
to which the soul is itself subject. Hence, convertendo^ the motion of the 
soul must be that of the body. viz. spatial motion (<j>opd\ whether the soul 
moves as a whole or by successive movements of its parts, the whole remaining 
at rest. If so, it would be possible for the soul to leave the body and return 
to it, and the resurrection of the dead would cease to be impossible. 

4O6 b 5 11. (6) It may be maintained that the soul is moved 
indirectly or per accidens. [A-'s own opinion, see 408 a 30 34.] In that case 
such motions might be imparted to it by external agency. But if this be admitted 
by our opponents, it is inconsistent for them to maintain that something (r) 
has self-motion in its essence, and (2) is at the same time moved by external 
agency, unless the concurrence of the impulses from within and from without 
is merely accidental. The soul however, if it is moved at all, is moved by 
objects of sense. 

4O6 b 11 15. (7) The self-motion of soul implies not only that 
it causes motion qud soul and in respect of its essential nature, but also that 
it is subject to motion qud soul. Now everything subject to motion or change 
in whatever respect undergoes a transition or transformation from one condition 
to another in that respect. If then the soul is moved qud soul, it is always 
passing out of that condition in which its essential nature consists [in other 
words, in such movement it quits one condition for another it is dislodged 
from the condition of its existence and loses its essential nature]. 

4O6 b 15 25. (8) If it be maintained with Democritus that the 
soul is subject to exactly the same motions which it communicates to the 
body, we shall enquire if the soul's remaining at rest is due to the same 
causes, a result which seems inexplicable. (9) And, generally, the facts show 
that it is not in this way that the soul moves the body, but through a species 
of purpose and thought. 

As to the method which is followed in the above objections, Bonitz well 
observes, Hermes vn. p. 421, " Gemeinsamer Charakter der einzelnen zur 
Widerlegung dieser Definition angewendeten Beweise ist, dass Aristoteles 
seine eignen Lehren iiber das Wesen, insbesondere iiber die Arten, der 
Bewegung als sichere Grundlage voraussetzt und durch Anwendung derselben 
auf die fragliche Definition zu Consequenzen fuhrt, welche entweder an sich 
unhaltbar sind oder doch der Absicht derer selbst widerstreiten, welche jene 
Definition aufgestellt haben." The same method is pursued throughout 
cc. 3 5 : A. deduces absurd and inconsistent conclusions by combining* the 
doctrines of his own system with the propositions which he undertakes to 
refute. He does not stop to enquire whether those who maintain these 
propositions would have accepted the doctrines of his own system. In the 
present case, there is the further difficulty that the mobility of the soul which 
he is combating is regarded as one and the same tenet when advanced by 
two opposite schools, viz. by the Pre-Socratics, of whom Democritus is the 
type, who considered soul to be something corporeal, and by the Platonists, 



240 NOTES I. 3 

who as emphatically declared it to be incorporeal. The cogency of the 
objections will naturally vary according as they are advanced against the one or 
the other. No doubt he tries to follow the rule which he lays down De Caelo 
II. 13, 294 b 10 3et TOV fj,\\ovTa KaXcos r}Tr)criv eWrartKoi/ elvai diet T&V ofcetW 
vo-Tao-tov r< yevei. The supply of objections is inexhaustible: but their 
relevancy to the subject is just what his opponents would dispute. In c. 4 he 
deals with harmony exactly as here he deals with motion. 

405 b 31 I'crws y^P---4^ a 2 KVT]<TIV. Two propositions are here repudiated 
as untrue and even impossible. The first is the proposition that soul is that 
which moves itself, as defined by Plato in the Laws (see note on 404 a 21). 
The second is the more general proposition that motion in any sense is an 
essential attribute of soul. In other words, it is false to say that soul moves 
itself, and further it is false to say that soul is moved at all. The term motion 
is used throughout in a wider sense than in the present day, viz. to express 
several varieties of change. To render it more precise A. often affixes /Ltera/SoXiJ 
(just as Plato does, e.g. Laws 894 A, c, E and 895 A, etc., v. Stallb. ad 893 C, p. 161, 
8940, p. 165), KLVTJO-LS teal /zero/SoX?}, motion, that is to say, change, Phys. IV. 10, 
2l8 b 19 fJLijdev dicxpepeTca \eyeiv rjfjuv ev TO) vrapovTi KLVYJCTLV ^ fterajSoXi^v. Sometimes, 
however, KLVTJCTIS is made a species of ^era/SoX?? : cf. Pfiys. v. 5, 229 a 31, b 13 sq* 
As we shall see below (406 a 12) motion includes not only (a) (f>opd, spatial motion, 
change of place, locomotion, Kara TOTTOJ/, the meaning which we now attach to 
the term motion, but also (b} afl^o-is-, growth and c^to-i?, decay, two forms of 
quantitative change, Kara TO TTOO-OI/, and (c) dXXouacrts, qualitative change, the 
internal alteration or transformation which the thing changed undergoes when, 
though it remains in being, it is modified in respect of its condition or character, 
Kara TO TTQLOV. These are the three species of motion finally recognised by 
A. in the Physics, where he employs the word as a scientific term and determines 
its connotation. Though his language varies, he must be taken to exclude 
from Kivrjcrcs proper the sense of yevfcris KOL $6opd, generation and destruction. 
See note on 406 a 12. For A/s attempt to reduce the other species to <opa, 
spatial motion, see note on a 16 inf. Finally what A. means by motion (KLVYIO-LS) 
must be carefully distinguished in another direction from what he means by 
evepyeta, active operation or actualisation. On this important question there 
will be more to say later, e.g. 417 a 1517, 425 b 26 426 a 8, 431 a i 7.

26, 20 27, 21 Sp.) gives a good abstract of the argument in the Physics. 

a 4. 8txs. The distinction is between independent and derivative motion, 
i.e. change, generally: not primarily, as the illustration might suggest, be- 
tween direct and indirect locomotion (e.g. the free motion of the ship and 



I. 3 405 b 3i 406 a 4 241 

the motion, by conveyance, of the passenger). It is a metaphysical or logical 
(cf. a 10, \yop.4vov) not a physical distinction. The principle on which it 
depends can be best understood if we go back to the fundamental antithesis 
between the logical subject and its accidents or attributes. Change or motion 
is predicated of the various substances or things, regarded as particulars. 
Each of these is a distinct something or whole, roSc n or o\ov, and the motion 
predicated of it belongs to it as such, r<5 elvai avrb o ea-n /ca0' avro, because it is 
what it is, independently of all other existing things. Thus icatf* avro is ex- 
plained by Kara T^V ovcriav. But besides the wholes which thus exist and 
are moved independently, we must take account of parts and accidents, the 
existence of which is conditioned by that of the things to which as parts and 
accidents they belong. Of such parts and accidents motion can also be predicated, 
but their motion, like their existence, will not be independent and unconditioned, 
but dependent, derivative and conditioned. In the Physics this distinction is 
usually expressed by Kara O-V^C^KOS KLVOVJJLCVOV as opposed to *a0* ar6 
K.t.vovp.vov, where Kara crvjj.p. conveys the idea of accessory, concomitant or 
adventitious. By a vague or extended use of the phrase ra Kara o-vpfi. 
Kivovp,va are sometimes made to include parts of a whole as well as accidents, 
both parts and accidents being regarded as accessories or concomitants. See 
e.g. Phys. vin. 4, 254 b 7 12, as contrasted with the more precise distinctions 
of Phys. V. i, 224 a 21 34, and compare Simpl. in Phys. 1207, 15 ra yap

a thing from its parts (Pkys. iv. 3, 211 b i). The choice of KCL&* erepov instead 
of Kara <rvfjL{3f3rjK.bs enables A. to include the case of the passenger, who is, 
strictly speaking, neither a part nor an accident of the ship which conveys 
him, though, qud moved, he may be regarded for the time being as one or 
the other, since his motion in the case supposed is as much conditioned by that 
of the ship as if he were the ship's mast or its tonnage. C SimpL in Phys.

observed, the whole is " moved " (e.g. healed) in respect or in virtue of a part. 
Cf. Phys. vili. 4, 254 b 7 12. Thus, then, Kara expresses the logical relation 
of dependence in the order of thought. We can think of the motion of a ship 
without implying motion of a passenger: we cannot think of the motion of the 
passenger from port to port without implying that of the ship. As is pointed 
out by Them. (15, 21 H., 27, 27 Sp.) and by Simpl. (in Phys. 802, 19), the 
passengers may be assumed to be at rest in the ship, for in any case their 
walking up and down the deck is not the species of motion with which they 
and the ship are propelled : and it is the latter motion alone with which the 
argument is here concerned. If the passenger misses the vessel, walking, his 
own mode of progression, will not avail him in the water. If this holds when B, 
TO K.a.6* Zrepov Kivovpcvov, is a particular thing separately existing, it holds 
a fortiori when B is a part (whether poptov o-v/jL<pvs or eruvexes) of A, ro *#* 
avrb Kivovpevov, by whose motion its own is conditioned : or again when B is 
an accident, whiteness or the height of three cubits (a 18) of A. For, as we 
saw, neither part nor accident can be thought of as existing, much less as being 
moved, independently of the particular thing, ovo-La or roSe , in which it inheres, 
It would be a mistake, then, to treat Kara as simply equivalent to VTTO. See Phys.

respectively belong, i.e. to the existences (ovo-tat) of which they are, in the widest 
sense, accidents (arvppfprjK&rd). rrjs Sfe ifrvx^s fo-nu, int. roVos-. The argument 
amounts to this : If soul is a thing to which the attribute motion essentially 
or of its own nature belongs, then it will be in space, and, what is more, will 
have a place peculiar to it, a region in the universe to which it tends. Them.

Thus Them, gives roVo* a different meaning here (a 21) from that which it 
has above (a 16). This is plausible, for otherwise, as M. Rodier remarks, 
A. would elaborate a second argument to obtain a conclusion already reached 
almost at a step.

Quae enim sequuntur ostendunt haec in universum dici, non de sola anima 
(Torstrik). This proposition holds of the four simple bodies, fire, air, earth 
and water ; each of which has its natural rectilinear motion, upward from 
the centre of the universe to its circumference, or downward from the circum- 
ference to the centre, according to its own proper region or locality (roVos-

direction. Similarly its tendency to move with its natural motion may be 
counteracted, and it may be thus brought to a standstill. Thus fire (according 
to A.) is a simple body whose natural motion is upwards ; but the pressure 
of the air, as in a strong wind, may either cause the flames to go actually 
downwards, or at any rate may hinder them from ascending : $la = Trapa <f>vcrw. 
Cf. Phys. v. 6, 230 a 29, De Resp. 472 a 18. Or, as each simple body has 
its own proper motion, a constrained or unnatural motion = that which naturally 
belongs to some other body : De CaeL I. 2, 269 a 7 ftia pcv yap v$ex Tai *&

The elements air and water rise above earth but sink below fire. Their 
motions, then, being directed to quarters of the universe intermediate between 
the extremity and the centre, may be justly termed u intermediate motions." 
" The same argument " is as follows : if the soul tends to move towards the 
intermediate regions of the universe, it will be composed of either air or

instead of a priori. We have to start with the motions of the body as prior and 
better known to us, 413 a n note, because that which essentially and in the

406 b I. TO Sfc orcofjia Kivcirai <f>op* wore Kal ^ ^v)Cn- Bonitz (Hermes VI r. 
pp. 421 8) thus sums up the argument of a 30 b 5 : It is a fact ((fralve- 
rat) that soul sets body in motion. For those who ascribe to soul self-motion, 
it is reasonable to assume that the soul pi'oduces those motions in the body 
to which it (the soul) is itself subject. Of the motions of body it is certain 
that they are motions in space. Hence the logical conclusion for the soul is 
&(rr Kal fj ^vxn^"f^6icrrafjLvrj t What (asks Bonitz, I.e. p. 423) do these words 
mean? The two premisses are (i) The motions of soul are those of the 
body, (2) the motions of the body are motions in space. In (2) only <opa, 
a ycvos Kivr)o-a>?, is posited, not the particular species (paSta-is, aXans, Trr^crtsr. 
Cf. 406 a 9 note, and Ind. Ar. 132 a 44). There can, then, be no other 
conclusion than this : " Hence the motions of soul are motions in space " 
(es kann mithin nichts anderes erschlossen werden, als: folglich sind die 
Bewegungen der Seele raumliche Bewegungen). The result thus obtained 
seems absolutely incontrovertible. Bonitz goes on to enquire : Can the 
conclusion logically required be found in the words of the text ? (Steht 
dies in dem vorliegenden Worten ?) It seems to me that this is undoubtedly 
the case if we make a pause after wore KCU ^ ^x*) L mt - Kwelrai <t>opaj. A.

simply excised. It may be objected to the minor premiss that the body under- 
goes not only <f>opa but also aXXo/coo-t? and aiS^rjcris. The reply is that, as we have 
seen (see note on a 16 sitpr.}, both aXXoxWi* and atigrjo-is imply <>opa and are at 
any rate ei/ TO'TTG). 

b 2. ficTapdXXot &v Kard TO <rp,a. Bonitz l.c. 3 having clearly laid down that 
the conclusion of A.'s syllogism ought to contain a determination of the kind of 
change or motion which belongs to soul, viz. motion in space, examines the 
traditional text to see whether this determination is implied (i) in ^tfrn/3aXXoi, 
(2) in xara ro o-3>pa, (3) in pcBta-rafjievrj. (i) Trend, explains " /z*raoXXot av, i.e. 
roTroy," but, if pTafia\\Lv of itself here meant " to move from place to place," 
as it unquestionably does in the passages cited, Ind. Ar. 458 b 50 54, then 
A. in his conclusion has expressed the general term, change or motion, and left 
the reader to supply for himself the particular kind of change or motion to 
be inferred from the premisses. This seems very improbable. Again, if (2) 
we look for what we want in KOTO ro o-ca/xa we do indeed find it there, provided 
that the words are understood with Simpl. 37, 4 rovrecm Kadairep <rS>p.a roTri/cfiff, 
and that this agreement between the motions of soul and body be construed 
generally, and not as an exact correspondence in every detail, such as is 
implied at b 15 sq., which would render impossible the further inference that 
the soul may leave the body and return to it. There is no objection on 
the score of language to interpreting ^erajSaXXew icara ro o-w/,ta " to undergo 
the same species of change as the body." But the expression is almost 
incredibly clumsy, because then the conclusion would be an exact repetition 
of the major premiss, ftcraj8aXX Kara ro o-oo/ia being identical with fj tfaxn 
KOL avrf) ravrrjv rrjv Kivrjtrtv Kivflrat rjv rb o-fta (a 32 sq.), while there is no 
inference from the minor at all, and in particular no technical term corre- 
sponding to <opa to indicate the kind of change or motion inferred for the 
soul. Can the missing complement to /ieraoXXoi av be discovered (3) in 
p.c0i<Trap.vr}? The verb is used Ind. Ar. 449 b 13 proprie de mutato loco. 
But Bonitz replies that the whole meaning of the words fteraaXXoi av... 
neBio-Tapevrj would form part of the conclusion from the premisses, whereas 
this whole meaning goes far beyond the premisses. Further, if /cara ro o-wfwx 
is to be taken with juetfio-rafiei'jy, the further inference that soul can leave 
the body and return to it is again rendered impossible. 

Thus failing to obtain from the text the conclusion logically required, 
Bonitz proposed to alter icara ro o-co/za into Kara roTroi'. In support of the 
emendation he urges that, in all places of his paraphrase which correspond 
to the words, Themistius has Kara rdVov : 16, 13 H,, 29, n Sp. ITCO^CVOV av OVT&

words are found in the text used by Simpl. (37, 4), whose explanation of them has 
been cited above. As I have already said, the end proposed by the emendation 
is as easily attained by excising /zrra/SaXXo*. av Kara TO o-wjua from the text 
as a clumsy marginal comment, by which some reader unfamiliar with A. J s 
ellipses supplied what seemed to him to be the missing conclusion. It will 
be observed that the words of Simplicius rovre<m KaQdirep cr^a TOTTIM? would 
be equally in point if his lemma stopped short at &O-TC KOL fj ^vxh^ while 
the explanation of Philop. (107, 20) favours an elliptical conclusion with &a-re 
quite as much as does that of Them. (16, 16 H., 29, 15 sq. Sp.), both already 
cited. It would of course be possible to place a full stop after 
by inserting 8* before av to make a new sentence /xcra/SaXXot S" mf 
This new sentence would not be the conclusion of the syllogism, and so far 
some of the difficulties pointed out by Bonitz would disappear, but others 
would remain. If we must retain and may not emend pcTapaXXoi av Kara 
TO erco/zo, I am inclined to accept Mr Shorey's suggestion (A.J. Ph. XXII. 153) 
that Kara TO cr>jj,a may be taken locally " within the body, 5J and not in the sense 
given to the words by Simplicius (37, 4). Cf. KOTO nav TO o-ojfta 408 a 16, where, 
however, motion is not implied. " This gives point," Mr Shorey urges, " to the 
following antithesis : (if it can move in the body) it would follow that it can also, 
Kciiy go forth from the body and return. The same thought seems to be 
implied in the comparison with the quicksilver," 406 b 18 sqq.

present themselves. There are two species of spatial motion. Either the 
whole of a thing may change its place : this is motion of translation. Or 
the parts may move relatively to each other while the whole remains in the 
same place, e.g. when a sphere revolves or a top spins. Cf. De Gen. ct Corr*

censured by Bonitz, I.e., p. 426, who remarks that to introduce the faculties 
of the soul at this point is quite inadmissible, since the inconsistencies 
which A. deduces from the theory under examination all relate to the nature 
of the soul itself conceived as existing and moving in space.

he had not a collation. Bonitz (I.e.) argues that the reading of the inferior 
MSS. ought here to be preferred to E, because it is not a question of possibilit}^ : 
that the soul moves in space has been demonstrated as necessarily true. Even 
granting this, A. might make a compendiary use of eVd/xcrai : " If this, as 
already demonstrated, is possible, a further possibility will follow, viz. etc." 
Torstrik himself regarded the variation here between what he calls the two 
editions as due merely to considerations of style: videtur autem correxisse, 
quia paulo ante usus erat formula ea quae est d de TOVTO a 32, an admission 
which goes a long way in the direction of those who see in the so-called

in space. Such absence from the body and return to it are common in the 
folklore and magic stories of all ages. Cf. Frazer, Golden Bough^ ch. ii. 2, 
" The nature of the soul," and ch. iv. 3, " The external soul in folk-tales." '

clause, ce except accidentally." What, we ask, is the exceptional case in 
which that which has the power of self-rnotion is also per accidens moved 
by something external? Philoponus thinks that the motion communicated 
by external force is never the same as that which the self-moving soul 
possesses in its own nature. But this is doubtful. Themistius and Simplicius 
agree in thinking that it is precisely the concurrence of the external impulse 
with the soul's self-motion which happens only incidentally.

bio rr\v Sfe t|nxTiv...ii diirep Ktvcirau This statement becomes clearer as 
A.'s own tlieories of ato-^cr^ and opcgis are unfolded in the present treatise, 
As to the former, we may anticipate by a reference to 416 b 33 sq., 417 a 13, 17 *?q., 
where KiveiarQai., Trao-^etv and aXXoioocris (a species of K.iv7)<ns\ are used almost 
indifferently to describe the effect which the atcrdrjTbv produces upon the soul in 
actual perception. Subsequently 417 b 2 sqq. fvepytiv is preferred (els auTo yap 
fj 7r idea-is KOI elf VTe\4^Lav 417 b 6 ; cf. 425 b 26 426 a 8, 431 a 4 7), and on 
the whole woieti/, ird<rx,civ are more in favour than Kivetv, Kiveia-Oai. For Kpegis 
it is sufficient to refer to in., cc. 10, n, e.g. 433 a 1830, 433 bii 18, 
433 b 27 434 a 9. Occasionally even the rational soul is said to be " moved " : 
e.g. 431 b 5 and possibly 433 a 24. 

bii aXXd JJ.TJV ical el Kt,vu,.i5 avrtjs Ka0' avrqv. Another objection* Motion 
is displacement, and therefore any motion of the soul would mean that the soul 
is displaced or dislodged from its nature, whence we are intended to infer that 
it would cease to be soul. So that the hypothesis of self-motion as belonging to 
the nature of soul is self-destructive. Alex. Aphr. discusses this expression, oV. 
<al \va-. II. 2. 46, 22 47, 27 (Bruns).

found in the Physics, but it can be easily deduced from the more abstract form 
of the definition usually given, viz. "the realisation of what is potentially 
existent as such," or " the actualisation of what is undeveloped." This may be

made clear by considering one or two of the species of motion, e.g. under 
qualitative change (aXXo/eao-is) a thing which was formerly white becomes black 
and then there is a displacement (eKcrraa-ts) of the quality " white." Again, take 
quantitative change : a tree grows to twice its former height, which has thus 
been displaced. Finally, and here the meaning of eKoraa-is is best seen, in the 
case of locomotion (<f>opa) from A to -Z?, the " place " or spatial position of the 
thing which has moved is no longer A but B. 

b 13. IgCcrratr* civ IK TT)S oticHas. The last three words are added because 
the soul is supposed to move by its very nature. The inference is obtained by 
pressing the analogy with the motion of material things regarded as displacement. 
Take the moving body of the previous note. When at B it is no longer at A, 
though this change of place leaves it in other respects unaffected : whereas 
aXXoiGxris destroys or modifies the former quality when it substitutes a new one, 
and atigrjo-t? alters the quantity of TO Ktvovpevov. Cf. Phys. vin. 7, 261 a 20, where 
A. is arguing that <popa is less liable to this u displacement of essence " than the

motion in general to the soul but movements corresponding exactly in detail to 
those of the body (406 a 31). It might have been held by any pre-Socratic 
philosopher who regarded the soul as a material thing enclosed in the body. 
The view implies (i) the soul is in the body, (2) the soul has definite spatial 
motions, (3) these it communicates to the body in which it resides. From 
Lucretius in. 370 3 it would appear that atoms of soul and atoms of body are, 
according to Democritus, arranged alternately in the animal, singula privis 
adposita.

Plato in putting his views into the mouth of Timaeus, the Pythagorean

a physical discourse would have been unsuitable in the mouth of Socrates.
