370 BC 
PARMENIDES 
by Plato 
translated by Benjamin Jowett 
PARMENIDES 

PERSONS OF THE DIALOGUE: CEPHALUS; ADEIMANTUS; GLAUCON; ANTIPHON; 
PYTHODORUS; SOCRATES; ZENO; PARMENIDES; ARISTOTELES. Cephalus 
rehearses a dialogue which is supposed to have been narrated in his 
presence by Antiphon, the half-brother of Adeimantus and Glaucon, to 
certain Clazomenians . 

We had come from our home at Clazomenae to Athens, and met 
Adeimantus and Glaucon in the Agora. Welcome, Cephalus, said 
Adeimantus, taking me by the hand; is there anything which we can do 
for you in Athens? 

Yes; that is why I am here; I wish to ask a favour of you. 

What may that be? he said. 

I want you to tell me the name of your half brother, which I have 
forgotten; he was a mere child when I last came hither from 
Clazomenae, but that was a long time ago; his father's name, if I 
remember rightly, was Pyrilampes? 

Yes, he said, and the name of our brother, Antiphon; but why do 
you ask? 

Let me introduce some countrymen of mine, I said; they are lovers of 
philosophy, and have heard that Antiphon was intimate with a certain 
Pythodorus, a friend of Zeno, and remembers a conversation which 
took place between Socrates, Zeno, and Parmenides many years ago, 
Pythodorus having often recited it to him. 

Quite true. 

And could we hear it? I asked. 

Nothing easier, he replied; when he was a youth he made a careful 
study of the piece; at present his thoughts run in another 
direction; like his grandfather Antiphon he is devoted to horses. But, 
if that is what you want, let us go and look for him; he dwells at 
Melita, which is quite near, and he has only just left us to go home. 

Accordingly we went to look for him; he was at home, and in the 
act of giving a bridle to a smith to be fitted. When he had done 
with the smith, his brothers told him the purpose of our visit; and he 
saluted me as an acquaintance whom he remembered from my former visit, 
and we asked him to repeat the dialogue. At first he was not very 
willing, and complained of the trouble, but at length he consented. He 
told us that Pythodorus had described to him the appearance of 
Parmenides and Zeno; they came to Athens, as he said, at the great 
Panathenaea; the former was, at the time of his visit, about 65 
years old, very white with age, but well favoured. Zeno was nearly 
40 years of age, tall and fair to look upon; in the days of his 
youth he was reported to have been beloved by Parmenides . He said that 
they lodged with Pythodorus in the Ceramicus, outside the wall, 
whither Socrates, then a very young man, came to see them, and many 
others with him; they wanted to hear the writings of Zeno, which had 
been brought to Athens for the first time on the occasion of their 
visit. These Zeno himself read to them in the absence of Parmenides, 
and had very nearly finished when Pythodorus entered, and with him 
Parmenides and Aristoteles who was afterwards one of the Thirty, and 
heard the little that remained of the dialogue. Pythodorus had heard 
Zeno repeat them before. 

When the recitation was completed, Socrates requested that the first 
thesis of the first argument might be read over again, and this having 
been done, he said: What is your meaning, Zeno? Do you maintain that 
if being is many, it must be both like and unlike, and that this is 
impossible, for neither can the like be unlike, nor the unlike like-is 
that your position? 

Just so, said Zeno. 



And if the unlike cannot be like, or the like unlike, then according 
to you, being could not be many; for this would involve an 
impossibility. In all that you say have you any other purpose except 
to disprove the being of the many? and is not each division of your 
treatise intended to furnish a separate proof of this, there being 
in all as many proofs of the not-being of the many as you have 
composed arguments? Is that your meaning, or have I misunderstood you? 

No, said Zeno; you have correctly understood my general purpose. 

I see, Parmenides, said Socrates, that Zeno would like to be not 
only one with you in friendship but your second self in his writings 
too; he puts what you say in another way, and would fain make 
believe that he is telling us something which is new. For you, in your 
poems, say The All is one, and of this you adduce excellent proofs; 
and he on the other hand says There is no many; and on behalf of 
this he offers overwhelming evidence. You affirm unity, he denies 
plurality. And so you deceive the world into believing that you are 
saying different things when really you are saying much the same. This 
is a strain of art beyond the reach of most of us. 

Yes, Socrates, said Zeno. But although you are as keen as a 
Spartan hound in pursuing the track, you do not fully apprehend the 
true motive of the composition, which is not really such an artificial 
work as you imagine; for what you speak of was an accident; there 
was no pretence of a great purpose; nor any serious intention of 
deceiving the world. The truth is, that these writings of mine were 
meant to protect the arguments of Parmenides against those who make 
fun of him and seek to show the many ridiculous and contradictory 
results which they suppose to follow from the affirmation of the 
one. My answer is addressed to the partisans of the many, whose attack 
I return with interest by retorting upon them that their hypothesis of 
the being of many, if carried out, appears to be still more ridiculous 
than the hypothesis of the being of one. Zeal for my master led me 
to write the book in the days of my youth, but some one stole the 
copy; and therefore I had no choice whether it should be published 
or not; the motive, however, of writing, was not the ambition of an 
elder man, but the pugnacity of a young one. This you do not seem to 
see, Socrates; though in other respects, as I was saying, your 
notion is a very just one. 

I understand, said Socrates, and quite accept your account. But tell 
me, Zeno, do you not further think that there is an idea of likeness 
in itself, and another idea of unlikeness, which is the opposite of 
likeness, and that in these two, you and I and all other things to 
which we apply the term many, participate-things which participate 
in likeness become in that degree and manner like; and so far as 
they participate in unlikeness become in that degree unlike, or both 
like and unlike in the degree in which they participate in both? And 
may not all things partake of both opposites, and be both like and 
unlike, by reason of this participation?-Where is the wonder? Now if a 
person could prove the absolute like to become unlike, or the absolute 
unlike to become like, that, in my opinion, would indeed be a 
wonder; but there is nothing extraordinary, Zeno, in showing that 
the things which only partake of likeness and unlikeness experience 
both. Nor, again, if a person were to show that all is one by 
partaking of one, and at the same time many by partaking of many, 
would that be very astonishing. But if he were to show me that the 
absolute one was many, or the absolute many one, I should be truly 
amazed. And so of all the rest: I should be surprised to hear that the 
natures or ideas themselves had these opposite qualities; but not if a 
person wanted to prove of me that I was many and also one. When he 
wanted to show that I was many he would say that I have a right and 
a left side, and a front and a back, and an upper and a lower half, 
for I cannot deny that I partake of multitude; when, on the other 
hand, he wants to prove that I am one, he will say, that we who are 
here assembled are seven, and that I am one and partake of the one. In 
both instances he proves his case. So again, if a person shows that 



such things as wood, stones, and the like, being many are also one, we 
admit that he shows the coexistence the one and many, but he does 
not show that the many are one or the one many; he is uttering not a 
paradox but a truism. If however, as I just now suggested, some one 
were to abstract simple notions of like, unlike, one, many, rest, 
motion, and similar ideas, and then to show that these admit of 
admixture and separation in themselves, I should be very much 
astonished. This part of the argument appears to be treated by you, 
Zeno, in a very spirited manner; but, as I was saying, I should be far 
more amazed if any one found in the ideas themselves which are 
apprehended by reason, the same puzzle and entanglement which you have 
shown to exist in visible objects. 

While Socrates was speaking, Pythodorus thought that Parmenides 
and Zeno were not altogether pleased at the successive steps of the 
argument; but still they gave the closest attention and often looked 
at one another, and smiled as if in admiration of him. When he had 
finished, Parmenides expressed their feelings in the following words :- 

Socrates, he said, I admire the bent of your mind towards 
philosophy; tell me now, was this your own distinction between ideas 
in themselves and the things which partake of them? and do you think 
that there is an idea of likeness apart from the likeness which we 
possess, and of the one and many, and of the other things which Zeno 
mentioned? 

I think that there are such ideas, said Socrates. 

Parmenides proceeded: And would you also make absolute ideas of 
the just and the beautiful and the good, and of all that class? 

Yes, he said, I should. 

And would you make an idea of man apart from us and from all other 
human creatures, or of fire and water? 

I am often undecided, Parmenides, as to whether I ought to include 
them or not. 

And would you feel equally undecided, Socrates, about things of 
which the mention may provoke a smile?-I mean such things as hair, 
mud, dirt, or anything else which is vile and paltry; would you 
suppose that each of these has an idea distinct from the actual 
objects with which we come into contact, or not? 

Certainly not, said Socrates; visible things like these are such 
as they appear to us, and I am afraid that there would be an absurdity 
in assuming any idea of them, although I sometimes get disturbed, 
and begin to think that there is nothing without an idea; but then 
again, when I have taken up this position, I run away, because I am 
afraid that I may fall into a bottomless pit of nonsense, and 
perish; and so I return to the ideas of which I was just now speaking, 
and occupy myself with them. 

Yes, Socrates, said Parmenides; that is because you are still young; 
the time will come, if I am not mistaken, when philosophy will have 
a firmer grasp of you, and then you will not despise even the 
meanest things; at your age, you are too much disposed to regard 
opinions of men. But I should like to know whether you mean that there 
are certain ideas of which all other things partake, and from which 
they derive their names; that similars, for example, become similar, 
because they partake of similarity; and great things become great, 
because they partake of greatness; and that just and beautiful 
things become just and beautiful, because they partake of justice 
and beauty? 

Yes, certainly, said Socrates that is my meaning. 

Then each individual partakes either of the whole of the idea or 
else of a part of the idea? Can there be any other mode of 
participation? 

There cannot be, he said. 

Then do you think that the whole idea is one, and yet, being one, is 
in each one of the many? 

Why not, Parmenides? said Socrates. 

Because one and the same thing will exist as a whole at the same 



time in many separate individuals, and will therefore be in a state of 
separation from itself. 

Nay, but the idea may be like the day which is one and the same in 
many places at once, and yet continuous with itself; in this way 
each idea may be one; and the same in all at the same time. 

I like your way, Socrates, of making one in many places at once. You 
mean to say, that if I were to spread out a sail and cover a number of 
men, there would be one whole including many-is not that your meaning? 

I think so. 

And would you say that the whole sail includes each man, or a part 
of it only, and different parts different men? 

The latter. 

Then, Socrates, the ideas themselves will be divisible, and things 
which participate in them will have a part of them only and not the 
whole idea existing in each of them? 

That seems to follow. 

Then would you like to say, Socrates, that the one idea is really 
divisible and yet remains one? 

Certainly not, he said. 

Suppose that you divide absolute greatness, and that of the many 
great things, each one is great in virtue of a portion of greatness 
less than absolute greatness-is that conceivable? 

No. 

Or will each equal thing, if possessing some small portion of 
equality less than absolute equality, be equal to some other thing 
by virtue of that portion only? 

Impossible . 

Or suppose one of us to have a portion of smallness; this is but a 
part of the small, and therefore the absolutely small is greater; if 
the absolutely small be greater, that to which the part of the small 
is added will be smaller and not greater than before. 

How absurd! 

Then in what way, Socrates, will all things participate in the 
ideas, if they are unable to participate in them either as parts or 
wholes? 

Indeed, he said, you have asked a question which is not easily 
answered . 

Well, said Parmenides, and what do you say of another question? 

What question? 

I imagine that the way in which you are led to assume one idea of 
each kind is as follows: -You see a number of great objects, and 
when you look at them there seems to you to be one and the same idea 
(or nature) in them all; hence you conceive of greatness as one. 

Very true, said Socrates. 

And if you go on and allow your mind in like manner to embrace in 
one view the idea of greatness and of great things which are not the 
idea, and -to compare them, will not another greatness arise, which 
will appear to be the source of all these? 

It would seem so. 

Then another idea of greatness now comes into view over and above 
absolute greatness, and the individuals which partake of it; and 
then another, over and above all these, by virtue of which they will 
all be great, and so each idea instead of being one will be infinitely 
multiplied . 

But may not the ideas, asked Socrates, be thoughts only, and have no 
proper existence except in our minds, Parmenides? For in that case 
each idea may still be one, and not experience this infinite 
multiplication . 

And can there be individual thoughts which are thoughts of nothing? 

Impossible, he said. 

The thought must be of something? 

Yes. 

Of something which is or which is not? 

Of something which is. 



Must it not be of a single something, which the thought recognizes 
as attaching to all, being a single form or nature? 

Yes. 

And will not the something which is apprehended as one and the 
same in all, be an idea? 

From that, again, there is no escape. 

Then, said Parmenides, if you say that everything else 
participates in the ideas, must you not say either that everything 
is made up of thoughts, and that all things think; or that they are 
thoughts but have no thought? 

The latter view, Parmenides, is no more rational than the previous 
one. In my opinion, the ideas are, as it were, patterns fixed in 
nature, and other things are like them, and resemblances of 
them-what is meant by the participation of other things in the 
ideas, is really assimilation to them. 

But if, said he, the individual is like the idea, must not the 
idea also be like the individual, in so far as the individual is a 
resemblance of the idea? That which is like, cannot be conceived of as 
other than the like of like. 

Impossible . 

And when two things are alike, must they not partake of the same 
idea? 

They must. 

And will not that of which the two partake, and which makes them 
alike, be the idea itself? 

Certainly . 

Then the idea cannot be like the individual, or the individual 
like the idea; for if they are alike, some further idea of likeness 
will always be coming to light, and if that be like anything else, 
another; and new ideas will be always arising, if the idea resembles 
that which partakes of it? 

Quite true. 

The theory, then that other things participate in the ideas by 
resemblance, has to be given up, and some other mode of 
participation devised? 

It would seem so. 

Do you see then, Socrates, how great is the difficulty of 
affirming the ideas to be absolute? 

Yes, indeed. 

And, further, let me say that as yet you only understand a small 
part of the difficulty which is involved if you make of each thing a 
single idea, parting it off from other things. 

What difficulty? he said. 

There are many, but the greatest of all is this: -If an opponent 
argues that these ideas, being such as we say they ought to be, must 
remain unknown, no one can prove to him that he is wrong, unless he 
who denies their existence be a man of great ability and knowledge, 
and is willing to follow a long and laborious demonstration; he will 
remain unconvinced, and still insist that they cannot be known. 

What do you mean, Parmenides? said Socrates. 

In the first place, I think, Socrates, that you, or any one who 
maintains the existence of absolute essences, will admit that they 
cannot exist in us . 

No, said Socrates; for then they would be no longer absolute. 

True, he said; and therefore when ideas are what they are in 
relation to one another, their essence is determined by a relation 
among themselves, and has nothing to do with the resemblances, or 
whatever they are to be termed, which are in our sphere, and from 
which we receive this or that name when we partake of them. And the 
things which are within our sphere and have the same names with 
them, are likewise only relative to one another, and not to the 
ideas which have the same names with them, but belong to themselves 
and not to them. 

What do you mean? said Socrates. 



I may illustrate my meaning in this way, said Parmenides : -A master 
has a slave; now there is nothing absolute in the relation between 
them, which is simply a relation of one man to another. But there is 
also an idea of mastership in the abstract, which is relative to the 
idea of slavery in the abstract. These natures have nothing to do with 
us, nor we with them; they are concerned with themselves only, and 
we with ourselves. Do you see my meaning? 

Yes, said Socrates, I quite see your meaning. 

And will not knowledge-I mean absolute knowledge-answer to 
absolute truth? 

Certainly . 

And each kind of absolute knowledge will answer to each kind of 
absolute being? 

Yes. 

But the knowledge which we have, will answer to the truth which we 
have; and again, each kind of knowledge which we have, will be a 
knowledge of each kind of being which we have? 

Certainly . 

But the ideas themselves, as you admit, we have not, and cannot 
have? 

No, we cannot. 

And the absolute natures or kinds are known severally by the 
absolute idea of knowledge? 

Yes. 

And we have not got the idea of knowledge? 

No. 

Then none of the ideas are known to us, because we have no share 
in absolute knowledge? 

I suppose not. 

Then the nature of the beautiful in itself, and of the good in 
itself, and all other ideas which we suppose to exist absolutely, 
are unknown to us? 

It would seem so. 

I think that there is a stranger consequence still. 

What is it? 

Would you, or would you not say, that absolute knowledge, if there 
is such a thing, must be a far more exact knowledge than our 
knowledge; and the same of beauty and of the rest? 

Yes. 

And if there be such a thing as participation in absolute knowledge, 
no one is more likely than God to have this most exact knowledge? 

Certainly . 

But then, will God, having absolute knowledge, have a knowledge of 
human things? 

Why not? 

Because, Socrates, said Parmenides, we have admitted that the 
ideas are not valid in relation to human things; nor human things in 
relation to them; the relations of either are limited to their 
respective spheres . 

Yes, that has been admitted. 

And if God has this perfect authority, and perfect knowledge, his 
authority cannot rule us, nor his knowledge know us, or any human 
thing; just as our authority does not extend to the gods, nor our 
knowledge know anything which is divine, so by parity of reason 
they, being gods, are not our masters, neither do they know the things 
of men. 

Yet, surely, said Socrates, to deprive God of knowledge is 
monstrous . 

These, Socrates, said Parmenides, are a few, and only a few of the 
difficulties in which we are involved if ideas really are and we 
determine each one of them to be an absolute unity. He who hears 
what may be said against them will deny the very existence of them-and 
even if they do exist, he will say that they must of necessity be 
unknown to man; and he will seem to have reason on his side, and as we 



were remarking just now, will be very difficult to convince; a man 
must be gifted with very considerable ability before he can learn that 
everything has a class and an absolute essence; and still more 
remarkable will he be who discovers all these things for himself, 
and having thoroughly investigated them is able to teach them to 
others . 

I agree with you, Parmenides, said Socrates; and what you say is 
very much to my mind. 

And yet, Socrates, said Parmenides, if a man, fixing his attention 
on these and the like difficulties, does away with ideas of things and 
will not admit that every individual thing has its own determinate 
idea which is always one and the same, he will have nothing on which 
his mind can rest; and so he will utterly destroy the power of 
reasoning, as you seem to me to have particularly noted. 

Very true, he said. 

But, then, what is to become of philosophy? Whither shall we turn, 
if the ideas are unknown? 

I certainly do not see my way at present. 

Yes, said Parmenides; and I think that this arises, Socrates, out of 
your attempting to define the beautiful, the just, the good, and the 
ideas generally, without sufficient previous training. I noticed 
your deficiency, when I heard you talking here with your friend 
Aristoteles, the day before yesterday. The impulse that carries you 
towards philosophy is assuredly noble and divine; but there is an 
art which is called by the vulgar idle talking, and which is of 
imagined to be useless; in that you must train and exercise 
yourself, now that you are young, or truth will elude your grasp. 

And what is the nature of this exercise, Parmenides, which you would 
recommend? 

That which you heard Zeno practising; at the same time, I give you 
credit for saying to him that you did not care to examine the 
perplexity in reference to visible things, or to consider the question 
that way; but only in reference to objects of thought, and to what may 
be called ideas. 

Why, yes, he said, there appears to me to be no difficulty in 
showing by this method that visible things are like and unlike and may 
experience anything. 

Quite true, said Parmenides; but I think that you should go a step 
further, and consider not only the consequences which flow from a 
given hypothesis, but also the consequences which flow from denying 
the hypothesis; and that will be still better training for you. 

What do you mean? he said. 

I mean, for example, that in the case of this very hypothesis of 
Zeno's about the many, you should inquire not only what will be the 
consequences to the many in relation to themselves and to the one, and 
to the one in relation to itself and the many, on the hypothesis of 
the being of the many, but also what will be the consequences to the 
one and the many in their relation to themselves and to each other, on 
the opposite hypothesis. Or, again, if likeness is or is not, what 
will be the consequences in either of these cases to the subjects of 
the hypothesis, and to other things, in relation both to themselves 
and to one another, and so of unlikeness; and the same holds good of 
motion and rest, of generation and destruction, and even of being 
and not-being. In a word, when you suppose anything to be or not to 
be, or to be in any way affected, you must look at the consequences in 
relation to the thing itself, and to any other things which you 
choose-to each of them singly, to more than one, and to all; and so of 
other things, you must look at them in relation to themselves and to 
anything else which you suppose either to be or not to be, if you 
would train yourself perfectly and see the real truth. 

That, Parmenides, is a tremendous business of which you speak, and I 
do not quite understand you; will you take some hypothesis and go 
through the steps?-then I shall apprehend you better. 

That, Socrates, is a serious task to impose on a man of my years. 



Then will you, Zeno? said Socrates. 

Zeno answered with a smile: -Let us make our petition to Parmenides 
himself, who is quite right in saying that you are hardly aware of the 
extent of the task which you are imposing on him; and if there were 
more of us I should not ask him, for these are not subjects which 
any one, especially at his age, can well speak of before a large 
audience; most people are not aware that this round-about progress 
through all things is the only way in which the mind can attain 
truth and wisdom. And therefore, Parmenides, I join in the request 
of Socrates, that I may hear the process again which I have not 
heard for a long time. 

When Zeno had thus spoken, Pythodorus, according to Antiphon's 
report of him, said, that he himself and Aristoteles and the whole 
company entreated Parmenides to give an example of the process. I 
cannot refuse, said Parmenides; and yet I feel rather like Ibycus, 
who, when in his old age, against his will, he fell in love, 
compared himself to an old racehorse, who was about to run in a 
chariot race, shaking with fear at the course he knew so well-this was 
his simile of himself. And I also experience a trembling when I 
remember through what an ocean of words I have to wade at my time of 
life. But I must indulge you, as Zeno says that I ought, and we are 
alone. Where shall I begin? And what shall be our first hypothesis, if 
I am to attempt this laborious pastime? Shall I begin with myself, and 
take my own hypothesis the one? and consider the consequences which 
follow on the supposition either of the being or of the not being of 
one? 

By all means, said Zeno. 

And who will answer me? he said. Shall I propose the youngest? He 
will not make difficulties and will be the most likely to say what 
he thinks; and his answers will give me time to breathe. 

I am the one whom you mean, Parmenides, said Aristoteles; for I am 
the youngest and at your service. Ask, and I will answer. 

Parmenides proceeded: If one is, he said, the one cannot be many? 

Impossible . 

Then the one cannot have parts, and cannot be a whole? 

Why not? 

Because every part is part of a whole; is it not? 

Yes. 

And what is a whole? would not that of which no part is wanting be a 
whole? 

Certainly . 

Then, in either case, the one would be made up of parts; both as 
being a whole, and also as having parts? 

To be sure. 

And in either case, the one would be many, and not one? 

True. 

But, surely, it ought to be one and not many? 

It ought. 

Then, if the one is to remain one, it will not be a whole, and 
will not have parts? 

No. 

But if it has no parts, it will have neither beginning, middle, 
nor end; for these would of course be parts of it. 

Right. 

But then, again, a beginning and an end are the limits of 
everything? 

Certainly . 

Then the one, having neither beginning nor end, is unlimited? 

Yes, unlimited. 

And therefore formless; for it cannot partake either of round or 
straight . 

But why? 

Why, because the round is that of which all the extreme points are 
equidistant from the centre? 



Yes. 

And the straight is that of which the centre intercepts the view 
of the extremes? 

True. 

Then the one would have parts and would be many, if it partook 
either of a straight or of a circular form? 

Assuredly . 

But having no parts, it will be neither straight nor round? 

Right. 

And, being of such a nature, it cannot be in any place, for it 
cannot be either in another or in itself. 

How so? 

Because if it were in another, it would be encircled by that in 
which it was, and would touch it at many places and with many parts; 
but that which is one and indivisible, and does not partake of a 
circular nature, cannot be touched all round in many places. 

Certainly not. 

But if, on the other hand, one were in itself, it would also be 
contained by nothing else but itself; that is to say, if it were 
really in itself; for nothing can be in anything which does not 
contain it. 

Impossible . 

But then, that which contains must be other than that which is 
contained? for the same whole cannot do and suffer both at once; and 
if so, one will be no longer one, but two? 

True. 

Then one cannot be anywhere, either in itself or in another? 

No. 

Further consider, whether that which is of such a nature can have 
either rest or motion. 

Why not? 

Why, because the one, if it were moved, would be either moved in 
place or changed in nature; for these are the only kinds of motion. 

Yes. 

And the one, when it changes and ceases to be itself, cannot be 
any longer one. 

It cannot. 

It cannot therefore experience the sort of motion which is change of 
nature? 

Clearly not. 

Then can the motion of the one be in place? 

Perhaps . 

But if the one moved in place, must it not either move round and 
round in the same place, or from one place to another? 

It must. 

And that which moves in a circle must rest upon a centre; and that 
which goes round upon a centre must have parts which are different 
from the centre; but that which has no centre and no parts cannot 
possibly be carried round upon a centre? 

Impossible . 

But perhaps the motion of the one consists in change of place? 

Perhaps so, if it moves at all. 

And have we not already shown that it cannot be in anything? 

Yes. 

Then its coming into being in anything is still more impossible; 
is it not? 

I do not see why. 

Why, because anything which comes into being in anything, can 
neither as yet be in that other thing while still coming into being, 
nor be altogether out of it, if already coming into being in it. 

Certainly not. 

And therefore whatever comes into being in another must have 
parts, and then one part may be in, and another part out of that 
other; but that which has no parts can never be at one and the same 



time neither wholly within nor wholly without anything. 

True. 

And is there not a still greater impossibility in that which has 
no parts, and is not a whole, coming into being anywhere, since it 
cannot come into being either as a part or as a whole? 

Clearly. 

Then it does not change place by revolving in the same spot, not 
by going somewhere and coming into being in something; nor again, by 
change in itself? 

Very true. 

Then in respect of any kind of motion the one is immoveable? 

Immoveable . 

But neither can the one be in anything, as we affirm. 

Yes, we said so. 

Then it is never in the same? 

Why not? 

Because if it were in the same it would be in something. 

Certainly . 

And we said that it could not be in itself, and could not be in 
other? 

True. 

Then one is never in the same place? 

It would seem not. 

But that which is never in the same place is never quiet or at rest? 

Never . 

One then, as would seem, is neither rest nor in motion? 

It certainly appears so. 

Neither will it be the same with itself or other; nor again, other 
than itself or other. 

How is that? 

If other than itself it would be other than one, and would not be 
one . 

True. 

And if the same with other, it would be that other, and not 
itself; so that upon this supposition too, it would not have the 
nature of one, but would be other than one? 

It would. 

Then it will not be the same with other, or other than itself? 

It will not. 

Neither will it be other than other, while it remains one; for not 
one, but only other, can be other than other, and nothing else. 

True. 

Then not by virtue of being one will it be other? 

Certainly not. 

But if not by virtue of being one, not by virtue of itself; and if 
not by virtue of itself, not itself, and itself not being other at 
all, will not be other than anything? 

Right. 

Neither will one be the same with itself. 

How not? 

Surely the nature of the one is not the nature of the same. 

Why not? 

It is not when anything becomes the same with anything that it 
becomes one. 

What of that? 

Anything which becomes the same with the many, necessarily becomes 
many and not one . 

True. 

But, if there were no difference between the one and the same, 
when a thing became the same, it would always become one; and when 
it became one, the same? 

Certainly . 

And, therefore, if one be the same with itself, it is not one with 
itself, and will therefore be one and also not one. 



Surely that is impossible. 

And therefore the one can neither be other than other, nor the 
same with itself. 

Impossible . 

And thus the one can neither be the same, nor other, either in 
relation to itself or other? 

No. 

Neither will the one be like anything or unlike itself or other. 

Why not? 

Because likeness is sameness of affections. 

Yes. 

And sameness has been shown to be of a nature distinct from oneness? 

That has been shown. 

But if the one had any other affection than that of being one, it 
would be affected in such a way as to be more than one; which is 
impossible . 

True. 

Then the one can never be so affected as to be the same either 
with another or with itself? 

Clearly not. 

Then it cannot be like another, or like itself? 

No. 

Nor can it be affected so as to be other, for then it would be 
affected in such a way as to be more than one. 

It would. 

That which is affected otherwise than itself or another, will be 
unlike itself or another, for sameness of affections is likeness. 

True. 

But the one, as appears, never being affected otherwise, is never 
unlike itself or other? 

Never . 

Then the one will never be either like or unlike itself or other? 

Plainly not. 

Again, being of this nature, it can neither be equal nor unequal 
either to itself or to other. 

How is that? 

Why, because the one if equal must be of the same measures as that 
to which it is equal. 

True. 

And if greater or less than things which are commensurable with 
it, the one will have more measures than that which is less, and fewer 
than that which is greater? 

Yes. 

And so of things which are not commensurate with it, the one will 
have greater measures than that which is less and smaller than that 
which is greater. 

Certainly . 

But how can that which does not partake of sameness, have either the 
same measures or have anything else the same? 

Impossible . 

And not having the same measures, the one cannot be equal either 
with itself or with another? 

It appears so. 

But again, whether it have fewer or more measures, it will have as 
many parts as it has measures; and thus again the one will be no 
longer one but will have as many parts as measures. 

Right. 

And if it were of one measure, it would be equal to that measure; 
yet it has been shown to be incapable of equality. 

It has. 

Then it will neither partake of one measure, nor of many, nor of 
few, nor of the same at all, nor be equal to itself or another; nor be 
greater or less than itself, or other? 

Certainly . 



Well, and do we suppose that one can be older, or younger than 
anything, or of the same age with it? 

Why not? 

Why, because that which is of the same age with itself or other, 
must partake of equality or likeness of time; and we said that the one 
did not partake either of equality or of likeness? 

We did say so. 

And we also said, that it did not partake of inequality or 
unlikeness . 

Very true. 

How then can one, being of this nature, be either older or younger 
than anything, or have the same age with it? 

In no way. 

Then one cannot be older or younger, or of the same age, either with 
itself or with another? 

Clearly not. 

Then the one, being of this nature, cannot be in time at all; for 
must not that which is in time, be always growing older than itself? 

Certainly . 

And that which is older, must always be older than something which 
is younger? 

True . 

Then, that which becomes older than itself, also becomes at the same 
time younger than itself, if it is to have something to become older 
than . 

What do you mean? 

I mean this: -A thing does not need to become different from 
another thing which is already different; it is different, and if 
its different has become, it has become different; if its different 
will be, it will be different; but of that which is becoming 
different, there cannot have been, or be about to be, or yet be, a 
dif f erent-the only different possible is one which is becoming. 

That is inevitable. 

But, surely, the elder is a difference relative to the younger, 
and to nothing else. 

True. 

Then that which becomes older than itself must also, at the same 
time, become younger than itself? 

Yes. 

But again, it is true that it cannot become for a longer or for a 
shorter time than itself, but it must become, and be, and have become, 
and be about to be, for the same time with itself? 

That again is inevitable. 

Then things which are in time, and partake of time, must in every 
case, I suppose, be of the same age with themselves; and must also 
become at once older and younger than themselves? 

Yes. 

But the one did not partake of those affections? 

Not at all. 

Then it does not partake of time, and is not in any time? 

So the argument shows . 

Well, but do not the expressions "was," and "has become," and "was 
becoming, " signify a participation of past time? 

Certainly . 

And do not "will be, " "will become, " "will have become, " signify a 
participation of future time? 

Yes. 

And "is," or "becomes," signifies a participation of present time? 

Certainly . 

And if the one is absolutely without participation in time, it never 
had become, or was becoming, or was at any time, or is now become or 
is becoming, or is, or will become, or will have become, or will be, 
hereafter . 

Most true. 



But are there any modes of partaking of being other than these? 

There are none. 

Then the one cannot possibly partake of being? 

That is the inference. 

Then the one is not at all? 

Clearly not. 

Then the one does not exist in such way as to be one; for if it were 
and partook of being, it would already be; but if the argument is to 
be trusted, the one neither is nor is one? 

True. 

But that which is not admits of no attribute or relation? 

Of course not. 

Then there is no name, nor expression, nor perception, nor 
opinion, nor knowledge of it? 

Clearly not. 

Then it is neither named, nor expressed, nor opined, nor known, 
nor does anything that is perceive it. 

So we must infer. 

But can all this be true about the one? 

I think not. 

Suppose, now, that we return once more to the original hypothesis; 
let us see whether, on a further review, any new aspect of the 
question appears . 

I shall be very happy to do so. 

We say that we have to work out together all the consequences, 
whatever they may be, which follow, if the one is? 

Yes. 

Then we will begin at the beginning : -If one is, can one be, and 
not partake of being? 

Impossible . 

Then the one will have being, but its being will not be the same 
with the one; for if the same, it would not be the being of the one; 
nor would the one have participated in being, for the proposition that 
one is would have been identical with the proposition that one is one; 
but our hypothesis is not if one is one, what will follow, but if 
one is: -am I not right? 

Quite right. 

We mean to say, that being has not the same significance as one? 

Of course. 

And when we put them together shortly, and say "One is," that is 
equivalent to saying, "partakes of being"? 

Quite true. 

Once more then let us ask, if one is what will follow. Does not this 
hypothesis necessarily imply that one is of such a nature as to have 
parts? 

How so? 

In this way:-If being is predicated of the one, if the one is, and 
one of being, if being is one; and if being and one are not the 
same; and since the one, which we have assumed, is, must not the 
whole, if it is one, itself be, and have for its parts, one and being? 

Certainly . 

And is each of these parts-one and being to be simply called a part, 
or must the word "part" be relative to the word "whole"? 

The latter. 

Then that which is one is both a whole and has a part? 

Certainly . 

Again, of the parts of the one, if it is-I mean being and one-does 
either fail to imply the other? is the one wanting to being, or 
being to the one? 

Impossible . 

Thus, each of the parts also has in turn both one and being, and 
is at the least made up of two parts; and the same principle goes on 
for ever, and every part whatever has always these two parts; for 



being always involves one, and one being; so that one is always 
disappearing, and becoming two. 

Certainly . 

And so the one, if it is, must be infinite in multiplicity? 

Clearly. 

Let us take another direction. 

What direction? 

We say that the one partakes of being and therefore it is? 

Yes. 

And in this way, the one, if it has being, has turned out to be 
many? 

True. 

But now, let us abstract the one which, as we say, partakes of 
being, and try to imagine it apart from that of which, as we say, it 
partakes-will this abstract one be one only or many? 

One, I think. 

Let us see: -Must not the being of one be other than one? for the one 
is not being, but, considered as one, only partook of being? 

Certainly . 

If being and the one be two different things, it is not because 
the one is one that it is other than being; nor because being is being 
that it is other than the one; but they differ from one another in 
virtue of otherness and difference. 

Certainly . 

So that the other is not the same either with the one or with being? 

Certainly not. 

And therefore whether we take being and the other, or being and 
the one, or the one and the other, in every such case we take two 
things, which may be rightly called both. 

How so. 

In this way-you may speak of being? 

Yes. 

And also of one? 

Yes. 

Then now we have spoken of either of them? 

Yes. 

Well, and when I speak of being and one, I speak of them both? 

Certainly . 

And if I speak of being and the other, or of the one and the 
other-in any such case do I not speak of both? 

Yes. 

And must not that which is correctly called both, be also two? 

Undoubtedly. 

And of two things how can either by any possibility not be one? 

It cannot. 

Then, if the individuals of the pair are together two, they must 
be severally one? 

Clearly. 

And if each of them is one, then by the addition of any one to any 
pair, the whole becomes three? 

Yes. 

And three are odd, and two are even? 

Of course. 

And if there are two there must also be twice, and if there are 
three there must be thrice; that is, if twice one makes two, and 
thrice one three? 

Certainly . 

There are two, and twice, and therefore there must be twice two; and 
there are three, and there is thrice, and therefore there must be 
thrice three? 

Of course. 

If there are three and twice, there is twice three; and if there are 
two and thrice, there is thrice two? 

Undoubtedly. 



Here, then, we have even taken even times, and odd taken odd 
times, and even taken odd times, and odd taken even times. 

True. 

And if this is so, does any number remain which has no necessity 
to be? 

None whatever. 

Then if one is, number must also be? 

It must. 

But if there is number, there must also be many, and infinite 
multiplicity of being; for number is infinite in multiplicity, and 
partakes also of being: am I not right? 

Certainly . 

And if all number participates in being, every part of number will 
also participate? 

Yes. 

Then being is distributed over the whole multitude of things, and 
nothing that is, however small or however great, is devoid of it? And, 
indeed, the very supposition of this is absurd, for how can that which 
is, be devoid of being? 

In no way. 

And it is divided into the greatest and into the smallest, and 
into being of all sizes, and is broken up more than all things; the 
divisions of it have no limit. 

True. 

Then it has the greatest number of parts? 

Yes, the greatest number. 

Is there any of these which is a part of being, and yet no part? 

Impossible . 

But if it is at all and so long as it is, it must be one, and cannot 
be none? 

Certainly . 

Then the one attaches to every single part of being, and does not 
fail in any part, whether great or small, or whatever may be the 
size of it? 

True. 

But reflect: -an one in its entirety, be in many places at the same 
time? 

No; I see the impossibility of that. 

And if not in its entirety, then it is divided; for it cannot be 
present with all the parts of being, unless divided. 

True. 

And that which has parts will be as many as the parts are? 

Certainly . 

Then we were wrong in saying just now, that being was distributed 
into the greatest number of parts. For it is not distributed into 
parts more than the one, into parts equal to the one; the one is never 
wanting to being, or being to the one, but being two they are co-equal 
and coextensive. 

Certainly that is true. 

The one itself, then, having been broken up into parts by being, 
is many and infinite? 

True. 

Then not only the one which has being is many, but the one itself 
distributed by being, must also be many? 

Certainly . 

Further, inasmuch as the parts are parts of a whole, the one, as a 
whole, will be limited; for are not the parts contained the whole? 

Certainly . 

And that which contains, is a limit? 

Of course. 

Then the one if it has being is one and many, whole and parts, 
having limits and yet unlimited in number? 

Clearly. 

And because having limits, also having extremes? 



Certainly . 

And if a whole, having beginning and middle and end. For can 
anything be a whole without these three? And if any one of them is 
wanting to anything, will that any longer be a whole? 

No. 

Then the one, as appears, will have beginning, middle, and end. 

It will. 

But, again, the middle will be equidistant from the extremes; or 
it would not be in the middle? 

Yes. 

Then the one will partake of figure, either rectilinear or round, or 
a union of the two? 

True. 

And if this is the case, it will be both in itself and in another 
too . 

How? 

Every part is in the whole, and none is outside the whole. 

True. 

And all the parts are contained by the whole? 

Yes. 

And the one is all its parts, and neither more nor less than all? 

No. 

And the one is the whole? 

Of course. 

But if all the parts are in the whole, and the one is all of them 
and the whole, and they are all contained by the whole, the one will 
be contained by the one; and thus the one will be in itself. 

That is true. 

But then, again, the whole is not in the parts-neither in all the 
parts, nor in some one of them. For if it is in all, it must be in 
one; for if there were any one in which it was not, it could not be in 
all the parts; for the part in which it is wanting is one of all, 
and if the whole is not in this, how can it be in them all? 

It cannot. 

Nor can the whole be in some of the parts; for if the whole were 
in some of the parts, the greater would be in the less, which is 
impossible . 

Yes, impossible. 

But if the whole is neither in one, nor in more than one, nor in all 
of the parts, it must be in something else, or cease to be anywhere at 
all? 

Certainly . 

If it were nowhere, it would be nothing; but being a whole, and 
not being in itself, it must be in another. 

Very true. 

The one then, regarded as a whole, is in another, but regarded as 
being all its parts, is in itself; and therefore the one must be 
itself in itself and also in another. 

Certainly . 

The one then, being of this nature, is of necessity both at rest and 
in motion? 

How? 

The one is at rest since it is in itself, for being in one, and 
not passing out of this, it is in the same, which is itself. 

True. 

And that which is ever in the same, must be ever at rest? 

Certainly . 

Well, and must not that, on the contrary, which is ever in other, 
never be in the same; and if never in the same, never at rest, and 
if not at rest, in motion? 

True. 

Then the one being always itself in itself and other, must always be 
both at rest and in motion? 

Clearly. 



And must be the same with itself, and other than itself; and also 
the same with the others, and other than the others; this follows from 
its previous affections. 

How so? 

Every thing in relation to every other thing, is either the same 
or other; or if neither the same nor other, then in the relation of 
a part to a whole, or of a whole to a part. 

Clearly. 

And is the one a part of itself? 

Certainly not. 

Since it is not a part in relation to itself it cannot be related to 
itself as whole to part? 

It cannot. 

But is the one other than one? 

No. 

And therefore not other than itself? 

Certainly not. 

If then it be neither other, nor a whole, nor a part in relation 
to itself, must it not be the same with itself? 

Certainly . 

But then, again, a thing which is in another place from "itself," if 
this "itself" remains in the same place with itself, must be other 
than "itself," for it will be in another place? 

True. 

Then the one has been shown to be at once in itself and in another? 

Yes. 

Thus, then, as appears, the one will be other than itself? 

True. 

Well, then, if anything be other than anything, will it not be other 
than that which is other? 

Certainly . 

And will not all things that are not one, be other than the one, and 
the one other than the not-one? 

Of course. 

Then the one will be other than the others? 

True. 

But, consider : -Are not the absolute same, and the absolute other, 
opposites to one another? 

Of course. 

Then will the same ever be in the other, or the other in the same? 

They will not. 

If then the other is never in the same, there is nothing in which 
the other is during any space of time; for during that space of 
time, however small, the other would be in the game. Is not that true? 

Yes. 
And since the other-is never in the same, it can never be in anything 
that is. 

True. 

Then the other will never be either in the not one, or in the one? 

Certainly not. 

Then not by reason of otherness is the one other than the not-one, 
or the not-one other than the one. 

No. 

Nor by reason of themselves will they be other than one another, 
if not partaking of the other. 

How can they be? 

But if they are not other, either by reason of themselves or of 
the other, will they not altogether escape being other than one 
another? 

They will . 

Again, the not-one cannot partake of the one; otherwise it would not 
have been not-one, but would have been in some way one. 

True. 

Nor can the not-one be number; for having number, it would not 



have been not-one at all. 

It would not. 

Again, is the not-one part of the one; or rather, would it not in 
that case partake of the one? 

It would. 

If then, in every point of view, the one and the not-one are 
distinct, then neither is the one part or whole of the not-one, nor is 
the not-one part or whole of the one? 

No. 

But we said that things which are neither parts nor wholes of one 
another, nor other than one another, will be the same with one 
another: -so we said? 

Yes. 

Then shall we say that the one, being in this relation to the 
not-one, is the same with it? 

Let us say so. 

Then it is the same with itself and the others, and also other 
than itself and the others. 

That appears to be the inference. And it will also be like and 
unlike itself and the others? 

Perhaps . 

Since the one was shown to be other than the others, the others will 
also be other than the one. 

Yes. 

And the one is other than the others in the same degree that the 
others are other than it, and neither more nor less? 

True. 

And if neither more nor less, then in a like degree? 

Yes. 

In virtue of the affection by which the one is other than others and 
others in like manner other than it, the one will be affected like the 
others and the others like the one. 

How do you mean? 

I may take as an illustration the case of names: You give a name 
to a thing? 

Yes. 

And you may say the name once or oftener? 

Yes. 

And when you say it once, you mention that of which it is the 
name? and when more than once, is it something else which you mention? 
or must it always be the same thing of which you speak, whether you 
utter the name once or more than once? 

Of course it is the same. 

And is not "other" a name given to a thing? 

Certainly . 

Whenever, then, you use the word "other, " whether once or oftener, 
you name that of which it is the name, and to no other do you give the 
name? 

True. 

Then when we say that the others are other than the one, and the one 
other than the others, in repeating the word "other" we speak of 
that nature to which the name is applied, and of no other? 

Quite true. 

Then the one which is other than others, and the other which is 
other than the one, in that the word "other" is applied to both, 
will be in the same condition; and that which is in the same condition 
is like? 

Yes. 

Then in virtue of the affection by which the one is other than the 
others, every thing will be like every thing, for every thing is other 
than every thing. 

True. 

Again, the like is opposed to the unlike? 

Yes. 



And the other to the same? 

True again. 

And the one was also shown to be the same with the others? 

Yes. 

And to be, the same with the others is the opposite of being other 
than the others? 

Certainly . 

And in that it was other it was shown to be like? 

Yes. 

But in that it was the same it will be unlike by virtue of the 
opposite affection to that which made it and this was the affection of 
otherness . 

Yes. 

The same then will make it unlike; otherwise it will not be the 
opposite of the other. 

True. 

Then the one will be both like and unlike the others; like in so far 
as it is other, and unlike in so far as it is the same. 

Yes, that argument may be used. 

And there is another argument. 

What? 

In so far as it is affected in the same way it is not affected 
otherwise, and not being affected otherwise is not unlike, and not 
being unlike, is like; but in so far as it is affected by other it 
is otherwise, and being otherwise affected is unlike. 

True. 

Then because the one is the same with the others and other than 
the others, on either of these two grounds, or on both of them, it 
will be both like and unlike the others? 

Certainly . 

And in the same way as being other than itself, and the same with 
itself on either of these two grounds and on both of them, it will 
be like and unlike itself. 

Of course. 

Again, how far can the one touch or not touch itself and 
others? -Consider . 

I am considering. 

The one was shown to be in itself which was a whole? 

True. 

And also in other things? 

Yes. 

In so far as it is in other things it would touch other things, 
but in so far as it is in itself it would be debarred from touching 
them, and would touch itself only. 

Clearly. 

Then the inference is that it would touch both? 

It would. 

But what do you say to a new point of view? Must not that which is 
to touch another be next to that which it is to touch, and occupy 
the place nearest to that in which what it touches is situated? 

True. 

Then the one, if it is to touch itself, ought to be situated next to 
itself, and occupy the place next to that in which itself is? 

It ought. 

And that would require that the one should be two, and be in two 
places at once, and this, while it is one, will never happen. 

No. 

Then the one cannot touch itself any more than it can be two? 

It cannot. 

Neither can it touch others . 

Why not? 

The reason is, that whatever is to touch another must be in 
separation from, and next to, that which it is to touch, and no 
third thing can be between them. 



True. 

Two things, then, at the least ate necessary to make contact 
possible? 

They are. 

And if to the two a third be added in due order, the number of terms 
will be three, and the contacts two? 

Yes. 

And every additional term makes one additional contact, whence it 
follows that the contacts are one less in number than the terms; the 
first two terms exceeded the number of contacts by one, and the 
whole number of terms exceeds the whole number of contacts by one in 
like manner; and for every one which is afterwards added to the number 
of terms, one contact is added to the contacts. 

True. 

Whatever is the whole number of things, the contacts will be 
always one less. 

True. 

But if there be only one, and not two, there will be no contact? 

How can there be? 

And do we not say that the others being other than the one are not 
one and have no part in the one? 

True. 

Then they have no number, if they have no one in them? 

Of course not. 

Then the others are neither one nor two, nor are they called by 
the name of any number? 

No. 

One, then, alone is one, and two do not exist? 

Clearly not. 

And if there are not two, there is no contact? 

There is not. 

Then neither does the one touch the others, nor the others the 
one, if there is no contact? 

Certainly not. 

For all which reasons the one touches and does not touch itself 
and the others? 

True. 

Further-is the one equal and unequal to itself and others? 

How do you mean? 

If the one were greater or less than the others, or the others 
greater or less than the one, they would not be greater or less than 
each other in virtue of their being the one and the others; but, if in 
addition to their being what they are they had equality, they would be 
equal to one another, or if the one had smallness and the others 
greatness, or the one had greatness and the others smallness-whichever 
kind had greatness would be greater, and whichever had smallness would 
be smaller? 

Certainly . 

Then there are two such ideas as greatness and smallness; for if 
they were not they could not be opposed to each other and be present 
in that which is. 

How could they? 

If, then, smallness is present in the one it will be present 
either in the whole or in a part of the whole? 

Certainly . 

Suppose the first; it will be either co-equal and co-extensive 
with the whole one, or will contain the one? 

Clearly. 

If it be co-extensive with the one it will be coequal with the 
one, or if containing the one it will be greater than the one? 

Of course. 

But can smallness be equal to anything or greater than anything, and 
have the functions of greatness and equality and not its own 
functions? 



Impossible . 

Then smallness cannot be in the whole of one, but, if at all, in a 
part only? 

Yes. 

And surely not in all of a part, for then the difficulty of the 
whole will recur; it will be equal to or greater than any part in 
which it is . 

Certainly . 

Then smallness will not be in anything, whether in a whole or in a 
part; nor will there be anything small but actual smallness. 

True. 

Neither will greatness be in the one, for if greatness be in 
anything there will be something greater other and besides greatness 
itself, namely, that in which greatness is; and this too when the 
small itself is not there, which the one, if it is great, must exceed; 
this, however, is impossible, seeing that smallness is wholly absent. 

True. 

But absolute greatness is only greater than absolute smallness, 
and smallness is only smaller than absolute greatness. 

Very true. 

Then other things not greater or less than the one, if they have 
neither greatness nor smallness; nor have greatness or smallness any 
power of exceeding or being exceeded in relation to the one, but 
only in relation to one another; nor will the one be greater or less 
than them or others, if it has neither greatness nor smallness. 

Clearly not. 

Then if the one is neither greater nor less than the others, it 
cannot either exceed or be exceeded by them? 

Certainly not. 

And that which neither exceeds nor is exceeded, must be on an 
equality; and being on an equality, must be equal. 

Of course. 

And this will be true also of the relation of the one to itself; 
having neither greatness nor smallness in itself, it will neither 
exceed nor be exceeded by itself, but will be on an equality with 
and equal to itself. 

Certainly . 

Then the one will be equal to both itself and the others? 

Clearly so. 

And yet the one, being itself in itself, will also surround and be 
without itself; and, as containing itself, will be greater than 
itself; and, as contained in itself, will be less; and will thus be 
greater and less than itself. 

It will. 

Now there cannot possibly be anything which is not included in the 
one and the others? 

Of course not. 

But, surely, that which is must always be somewhere? 

Yes. 

But that which is in anything will be less, and that in which it 
is will be greater; in no other way can one thing be in another. 

True. 

And since there is nothing other or besides the one and the 
others, and they must be in something, must they not be in one 
another, the one in the others and the others in the one, if they 
are to be anywhere? 

That is clear. 

But inasmuch as the one is in the others, the others will be greater 
than the one, because they contain the one, which will be less than 
the others, because it is contained in them; and inasmuch as the 
others are in the one, the one on the same principle will be greater 
than the others, and the others less than the one. 

True. 

The one, then, will be equal to and greater and less than itself and 



the others? 

Clearly. 

And if it be greater and less and equal, it will be of equal and 
more and less measures or divisions than itself and the others, and if 
of measures, also of parts? 

Of course. 

And if of equal and more and less measures or divisions, it will 
be in number more or less than itself and the others, and likewise 
equal in number to itself and to the others? 

How is that? 

It will be of more measures than those things which it exceeds, 
and of as many parts as measures; and so with that to which it is 
equal, and that than which it is less. 

True. 

And being greater and less than itself, and equal to itself, it will 
be of equal measures with itself and of more and fewer measures than 
itself; and if of measures then also of parts? 

It will. 

And being of equal parts with itself, it will be numerically equal 
to itself; and being of more parts, more, and being of less, less than 
itself? 

Certainly . 

And the same will hold of its relation to other things; inasmuch 
as it is greater than them, it will be more in number than them; and 
inasmuch as it is smaller, it will be less in number; and inasmuch 
as it is equal in size to other things, it will be equal to them in 
number . 

Certainly . 

Once more then, as would appear, the one will be in number both 
equal to and more and less than both itself and all other things. 

It will. 

Does the one also partake of time? And is it and does it become 
older and younger than itself and others, and again, neither younger 
nor older than itself and others, by virtue of participation in time? 

How do you mean? 

If one is, being must be predicated of it? 

Yes. 

But to be (einai) is only participation of being in present time, 
and to have been is the participation of being at a past time, and 
to be about to be is the participation of being at a future time? 

Very true. 

Then the one, since it partakes of being, partakes of time? 

Certainly . 

And is not time always moving forward? 

Yes. 

Then the one is always becoming older than itself, since it moves 
forward in time? 

Certainly . 

And do you remember that the older becomes older than that which 
becomes younger? 

I remember. 

Then since the one becomes older than itself, it becomes younger 
at the same time? 

Certainly . 

Thus, then, the one becomes older as well as younger than itself? 

Yes. 

And it is older (is it not?) when in becoming, it gets to the 
point of time, between "was" and "will be," which is "now": for surely 
in going from the past to the future, it cannot skip the present? 

No. 

And when it arrives at the present it stops from becoming older, and 
no longer becomes, but is older, for if it went on it would never be 
reached by the present, for it is the nature of that which goes on, to 



touch both the present and the future, letting go the present and 
seizing the future, while in process of becoming between them. 

True. 

But that which is becoming cannot skip the present; when it 
reaches the present it ceases to become, and is then whatever it may 
happen to be becoming. 

Clearly. 

And so the one, when in becoming older it reaches the present, 
ceases to become, and is then older. 

Certainly . 

And it is older than that than which it was becoming older, and it 
was becoming older than itself. 

Yes. 

And that which is older is older than that which is younger? 

True. 

Then the one is younger than itself, when in becoming older it 
reaches the present? 

Certainly . 

But the present is always present with the one during all its being; 
for whenever it is it is always now. 

Certainly . 

Then the one always both is and becomes older and younger than 
itself? 

Truly. 

And is it or does it become a longer time than itself or an equal 
time with itself? 

An equal time. 

But if it becomes or is for an equal time with itself, it is of 
the same age with itself? 

Of course. 

And that which is of the same age, is neither older nor younger? 

No. 

The one, then, becoming and being the same time with itself, neither 
is nor becomes older or younger than itself? 

I should say not. 

And what are its relations to other things? Is it or does it 
become older or younger than they? 

I cannot tell you. 

You can at least tell me that others than the one are more than 
the one-other would have been one, but the others have multitude, 
and are more than one? 

They will have multitude. 

And a multitude implies a number larger than one? 

Of course. 

And shall we say that the lesser or the greater is the first to come 
or to have come into existence? 

The lesser. 

Then the least is the first? And that is the one? 

Yes. 

Then the one of all things that have number is the first to come 
into being; but all other things have also number, being plural and 
not singular. 

They have . 

And since it came into being first it must be supposed to have 
come into being prior to the others, and the others later; and the 
things which came into being later, are younger than that which 
preceded them? And so the other things will be younger than the one, 
and the one older than other things? 

True. 

What would you say of another question? Can the one have come into 
being contrary to its own nature, or is that impossible? 

Impossible . 

And yet, surely, the one was shown to have parts; and if parts, then 
a beginning, middle and end? 



Yes. 

And a beginning, both of the one itself and of all other things, 
comes into being first of all; and after the beginning, the others 
follow, until you reach the end? 

Certainly . 

And all these others we shall affirm to be parts of the whole and of 
the one, which, as soon as the end is reached, has become whole and 
one? 

Yes; that is what we shall say. 

But the end comes last, and the one is of such a nature as to come 
into being with the last; and, since the one cannot come into being 
except in accordance with its own nature, its nature will require that 
it should come into being after the others, simultaneously with the 
end. 

Clearly. 

Then the one is younger than the others and the others older than 
the one . 

That also is clear in my judgment. 

Well, and must not a beginning or any other part of the one or of 
anything, if it be a part and not parts, being a part, be also of 
necessity one? 

Certainly . 

And will not the one come into being together with each 
part-together with the first part when that comes into being, and 
together with the second part and with all the rest, and will not be 
wanting to any part, which is added to any other part until it has 
reached the last and become one whole; it will be wanting neither to 
the middle, nor to the first, nor to the last, nor to any of them, 
while the process of becoming is going on? 

True. 

Then the one is of the same age with all the others, so that if 
the one itself does not contradict its own nature, it will be 
neither prior nor posterior to the others, but simultaneous; and 
according to this argument the one will be neither older nor younger 
than the others, nor the others than the one, but according to the 
previous argument the one will be older and younger than the others 
and the others than the one. 

Certainly . 

After this manner then the one is and has become. But as to its 
becoming older and younger than the others, and the others than the 
one, and neither older, nor younger, what shall we say? Shall we say 
as of being so also of becoming, or otherwise? 

I cannot answer. 

But I can venture to say, that even if one thing were older or 
younger than another, it could not become older or younger in a 
greater degree than it was at first; for equals added to unequals, 
whether to periods of time or to anything else, leave the difference 
between them the same as at first. 

Of course. Then that which is, cannot become older or younger than 
that which is, since the difference of age is always the same; the one 
is and has become older and the other younger; but they are no 
longer becoming so. 

True. 

And the one which is does not therefore become either older or 
younger than the others which are 

No. 

But consider whether they may not become older and younger in 
another way. 

In what way? 

Just as the one was proven to be older than the others and the 
others than the one. 

And what of that? 

If the one is older than the others, has come into being a longer 
time than the others. 



Yes. 

But consider again; if we add equal time to a greater and a less 
time, will the greater differ from the less time by an equal or by a 
smaller portion than before? 

By a smaller portion. 

Then the difference between the age of the one and the age of the 
others will not be afterwards so great as at first, but if an equal 
time be added to both of them they will differ less and less in age? 

Yes. 

And that which differs in age from some other less than formerly, 
from being older will become younger in relation to that other than 
which it was older? 

Yes, younger. 

And if the one becomes younger the others aforesaid will become 
older than they were before, in relation to the one. 

Certainly . 

Then that which had become younger becomes older relatively to 
that which previously had become and was older; it never really is 
older, but is always becoming, for the one is always growing on the 
side of youth and the other on the side of age. And in like manner the 
older is always in process of becoming younger than the younger; for 
as they are always going in opposite directions they become in ways 
the opposite to one another, the younger older than the older and 
the older younger than the younger. They cannot, however have 
become; for if they had already become they would be and not merely 
become. But that is impossible; for they are always becoming both 
older and younger than one another: the one becomes younger than the 
others because it was seen to be older and prior, and the others 
become older than the one because they came into being later; and in 
the same way the others are in the same relation to the one, because 
they were seen to be older, and prior to the one. 

That is clear. 

Inasmuch then, one thing does not become older or younger than 
another, in that they always differ from each other by an equal 
number, the one cannot become older or younger than the others, nor 
the other than the one; but inasmuch as that which came into being 
earlier and that which came into being later must continually differ 
from each other by a different portion-in this point of view the 
others must become older and younger than the one, and the one than 
the others . 

Certainly . 

For all these reasons, then, the one is and becomes older and 
younger than itself and the others, and neither is nor becomes older 
or younger than itself or the others. 

Certainly . 

But since the one partakes of time, and partakes of becoming older 
and younger, must it not also partake of the past, the present, and 
the future? 

Of course it must. 

Then the one was and is and will be, and was becoming and is 
becoming and will become? 

Certainly . 

And there is and was and will be something which is in relation to 
it and belongs to it? 

True. 

And since we have at this moment opinion and knowledge and 
perception of the one, there is opinion and knowledge and perception 
of it? 

Quite right. 

Then there is name and expression for it, and it is named and 
expressed, and everything of this kind which appertains to other: 
things appertains to the one. 

Certainly, that is true. 



Yet once more and for the third time, let us consider: If the one is 
both one and many, as we have described, and is, neither one nor many, 
and participates in time, must it not, in as far as it is one, at 
times partake of being, and in as far as it is not one, at times not 
partake of being? 

Certainly . 

But can it partake of being when not partaking of being, or not 
partake of being when partaking of being? 

Impossible . 

Then the one partakes and does not partake of being at different 
times, for that is the only way in which it can partake and not 
partake of the same. 

True. 

And is there not also a time at which it assumes being and 
relinquishes being-for how can it have and not have the same thing 
unless it receives and also gives it up at; some time? 

Impossible . 

And the assuming of being is what you would call becoming? 

I should. 

And the relinquishing of being you would call destruction? 

I should. 

The one then, as would appear, becomes and is destroyed by taking 
and giving up being. 

Certainly . 

And being one and many and in process of becoming and being 
destroyed, when it becomes one it ceases to be many, and when many, it 
ceases to be one? 

Certainly . 

And as it becomes one and many, must it not inevitably experience 
separation and aggregation? 

Inevitably . 

And whenever it becomes like and unlike it must be assimilated and 
dissimilated? 

Yes. 

And when it becomes greater or less or equal it must grow or 
diminish or be equalized? 

True. 

And when being in motion it rests, and when being at rest it changes 
to motion, it can surely be in no time at all? 

How can it? 

But that a thing which is previously at rest should be afterwards in 
motion, or previously in motion and afterwards at rest, without 
experiencing change, is impossible. 

Impossible . 

And surely there cannot be a time in which a thing can be at once 
neither in motion nor at rest? 

There cannot. 

But neither can it change without changing. 

True. 

When then does it change; for it cannot change either when at 
rest, or when in motion, or when in time? 

It cannot. 

And does this strange thing in which it is at the time of changing 
really exist? 

What thing? 

The moment. For the moment seems to imply a something out of which 
change takes place into either of two states; for the change is not 
from the state of rest as such, nor, from the state of motion as such; 
but there is this curious nature, which we call the moment lying 
between rest and motion, not being in any time; and into this and 
out of this what is in motion changes into rest, and what is at rest 
into motion. 

So it appears . 

And the one then, since it is at rest and also in motion, will 



change to either, for only in this way can it be in both. And in 
changing it changes in a moment, and when it is changing it will be in 
no time, and will not then be either in motion or at rest. 

It will not. 

And it will be in the same case in relation to the other changes, 
when it passes from being into cessation of being, or from not-being 
into becoming-then it passes between certain states of motion and 
rest, and, neither is nor is not, nor becomes nor is destroyed. 

Very true. 

And on the same principle, in the passage from one to many and 
from many to one, the one is neither one nor many, neither separated 
nor aggregated; and in the passage from like to unlike, and from 
unlike to like, it is neither like nor unlike, neither in a state of 
assimilation nor of dissimilation; and in the passage from small to 
great and equal and back again, it will be neither small nor great, 
nor equal, nor in a state of increase, or diminution, or equalization. 

True. 

All these, then, are the affections of the one, if the one has 
being . 

Of course. 

But if one is, what will happen to the others -is not that also to 
be considered? 

Yes. 

Let us show then, if one is, what will be the affections of the 
others than the one. 

Let us do so. 

Inasmuch as there are things other than the one, the others are 
not the one; for if they were they could not be other than the one. 
Very true. 

Very true. 

Nor are the others altogether without the one, but in a certain 
way they participate in the one. 

In what way? 

Because the others are other than the one inasmuch as they have 
parts; for if they had no parts they would be simply one. 

Right. 

And parts, as we affirm, have relation to a whole? 

So we say. 

And a whole must necessarily be one made up of many; and the parts 
will be parts of the one, for each of the parts is not a part of many, 
but of a whole. 

How do you mean? 

If anything were a part of many, being itself one of them, it will 
surely be a part of itself, which is impossible, and it will be a part 
of each one of the other parts, if of all; for if not a part of some 
one, it will be a part of all the others but this one, and thus will 
not be a part of each one; and if not a part of each, one it will 
not be a part of anyone of the many; and not being a part of any 
one, it cannot be a part or anything else of all those things of 
none of which it is anything. 

Clearly not. 

Then the part is not a part of the many, nor of all, but is of a 
certain single form, which we call a whole, being one perfect unity 
framed out of all-of this the part will be a part. 

Certainly . 

If, then, the others have parts, they will participate in the 
whole and in the one. 

True. 

Then the others than the one must be one perfect whole, having 
parts . 

Certainly . 

And the same argument holds of each part, for the part must 
participate in the one; for if each of the parts is a part, this 



means, I suppose, that it is one separate from the rest and 
self-related; otherwise it is not each. 

True. 

But when we speak of the part participating in the one, it must 
clearly be other than one; for if not, it would merely have 
participated, but would have been one; whereas only the itself can 
be one . 

Very true. 

Both the whole and the part must participate in the one; for the 
whole will be one whole, of which the parts will be parts; and each 
part will be one part of the whole which is the whole of the part. 

True. 

And will not the things which participate in the one, be other 
than it? 

Of course. 

And the things which are other than the one will be many; for if the 
things which are other than the one were neither one nor more than 
one, they would be nothing. 

True. 

But, seeing that the things which participate in the one as a 
part, and in the one as a whole, are more than one, must not those 
very things which participate in the one be infinite in number? 

How so? 

Let us look at the matter thus: -Is it not a fact that in partaking 
of the one they are not one, and do not partake of the one at the very 
time, when they are partaking of it? 

Clearly. 

They do so then as multitudes in which the one is not present? 

Very true. 

And if we were to abstract from them in idea the very smallest 
fraction, must not that least fraction, if it does not partake of 
the one, be a multitude and not one? 

It must. 

And if we continue to look at the other side of their nature, 
regarded simply, and in itself, will not they, as far as we see 
them, be unlimited in number? 

Certainly . 

And yet, when each several part becomes a part, then the parts 
have a limit in relation to the whole and to each other, and the whole 
in relation to the parts . 

Just so. 

The result to the others than the one is that of themselves and 
the one appears to create a new element in them which gives to them 
limitation in relation to one another; whereas in their own nature 
they have no limit. 

That is clear. 

Then the others than the one, both as whole and parts, are infinite, 
and also partake of limit. 

Certainly . 

Then they are both like and unlike one another and themselves. 

How is that? 

Inasmuch as they are unlimited in their own nature, they are all 
affected in the same way. 

True. 

And inasmuch as they all partake of limit, they are all affected 
in the same way. 

Of course. 

But inasmuch as their state is both limited and unlimited, they 
are affected in opposite ways. 

Yes. 

And opposites are the most unlike of things. 

Certainly . 

Considered, then, in regard to either one of their affections, 
they will be like themselves and one another; considered in 



reference to both of them together, most opposed and most unlike. 

That appears to be true. 

Then the others are both like and unlike themselves and one another? 

True. 

And they are the same and also different from one another, and in 
motion and at rest, and experience every sort of opposite affection, 
as may be proved without difficulty of them, since they have been 
shown to have experienced the affections aforesaid? 

True. 

Suppose, now, that we leave the further discussion of these 
matters as evident, and consider again upon the hypothesis that the 
one is, whether opposite of all this is or is not equally true of 
the others . 

By all means . 

Then let us begin again, and ask, If one is, what must be the 
affections of the others? 

Let us ask that question. 

Must not the one be distinct from the others, and the others from 
the one? 

Why so? 

Why, because there is nothing else beside them which is distinct 
from both of them; for the expression "one and the others" includes 
all things . 

Yes, all things. 

Then we cannot suppose that there is anything different from them in 
which both the one and the others might exist? 

There is nothing. 

Then the one and the others are never in the same? 

True . 

Then they are separated from each other? 

Yes. 

And we surely cannot say that what is truly one has parts? 

Impossible . 

Then the one will not be in the others as a whole, nor as part, if 
it be separated from the others, and has no parts? 

Impossible . 

Then there is no way in which the others can partake of the one, 
if they do not partake either in whole or in part? 

It would seem not. 

Then there is no way in which the others are one, or have in 
themselves any unity? 

There is not. 

Nor are the others many; for if they were many, each part of them 
would be a part of the whole; but now the others, not partaking in any 
way of the one, are neither one nor many, nor whole, nor part. 

True. 

Then the others neither are nor contain two or three, if entirely 
deprived of the one? 

True. 

Then the others are neither like nor unlike the one, nor is likeness 
and unlikeness in them; for if they were like and unlike, or had in 
them likeness and unlikeness, they would have two natures in them 
opposite to one another. 

That is clear. 

But for that which partakes of nothing to partake of two things 
was held by us to be impossible? 

Impossible . 

Then the others are neither like nor unlike nor both, for if they 
were like or unlike they would partake of one of those two natures, 
which would be one thing, and if they were both they would partake 
of opposites which would be two things, and this has been shown to 
be impossible. 

True. 



Therefore they are neither the same, nor other, nor in motion, nor 
at rest, nor in a state of becoming, nor of being destroyed, nor 
greater, nor less, nor equal, nor have they experienced anything 
else of the sort; for, if they are capable of experiencing any such 
affection, they will participate in one and two and three, and odd and 
even, and in these, as has been proved, they do not participate, 
seeing that they are altogether and in every way devoid of the one. 

Very true. 

Therefore if one is, the one is all things, and also nothing, both 
in relation to itself and to other things. 

Certainly . 

Well, and ought we not to consider next what will be the consequence 
if the one is not? 

Yes; we ought. 

What is the meaning of the hypothesis-If the one is not; is there 
any difference between this and the hypothesis-If the not one is not? 

There is a difference, certainly. 

Is there a difference only, or rather are not the two expressions-if 
the one is not, and if the not one is not, entirely opposed? 

They are entirely opposed. 

And suppose a person to say:-If greatness is not, if smallness is 
not, or anything of that sort, does he not mean, whenever he uses such 
an expression, that "what is not" is other than other things? 

To be sure. 

And so when he says "If one is not" he clearly means, that what 
"is not" is other than all others; we know what he means-do we not? 

Yes, we do. 

When he says "one," he says something which is known; and secondly 
something which is other than all other things; it makes no difference 
whether he predicate of one being or not being, for that which is said 
"not to be" is known to be something all the same, and is 
distinguished from other things. 

Certainly . 

Then I will begin again, and ask: If one is not, what are the 
consequences? In the first place, as would appear, there is a 
knowledge of it, or the very meaning of the words, "if one is not," 
would not be known. 

True. 

Secondly, the others differ from it, or it could not be described as 
different from the others? 

Certainly . 

Difference, then, belongs to it as well as knowledge; for in 
speaking of the one as different from the others, we do not speak of a 
difference in the others, but in the one. 

Clearly so. 

Moreover, the one that is not is something and partakes of 
relation to "that," and "this," and "these," and the like, and is an 
attribute of "this"; for the one, or the others than the one, could 
not have been spoken of, nor could any attribute or relative of the 
one that is not have been or been spoken of, nor could it have been 
said to be anything, if it did not partake of "some," or of the 
other relations just now mentioned. 

True. 

Being, then, cannot be ascribed to the one, since it is not; but the 
one that is not may or rather must participate in many things, if it 
and nothing else is not; if, however, neither the one nor the one that 
is not is supposed not to be, and we are speaking of something of a 
different nature, we can predicate nothing of it. But supposing that 
the one that is not and nothing else is not, then it must 
participate in the predicate "that," and in many others. 

Certainly . 

And it will have unlikeness in relation to the others, for the 
others being different from the one will be of a different kind. 



Certainly . 

And are not things of a different kind also other in kind? 

Of course. 

And are not things other in kind unlike? 

They are unlike. 

And if they are unlike the one, that which they are unlike will 
clearly be unlike them? 

Clearly so. 

Then the one will have unlikeness in respect of which the others are 
unlike it? 

That would seem to be true. 

And if unlikeness to other things is attributed to it, it must 
have likeness to itself. 

How so? 

If the one have unlikeness to one, something else must be meant; nor 
will the hypothesis relate to one; but it will relate to something 
other than one? 

Quite so. 

But that cannot be . 

No. 

Then the one must have likeness to itself? 

It must. 

Again, it is not equal to the others; for if it were equal, then 
it would at once be and be like them in virtue of the equality; but if 
one has no being, then it can neither be nor be like? 

It cannot. 

But since it is not equal to the others, neither can the others be 
equal to it? 

Certainly not. 

And things that are not equal are unequal? 

True. 

And they are unequal to an unequal? 

Of course. 

Then the one partakes of inequality, and in respect of this the 
others are unequal to it? 

Very true. 

And inequality implies greatness and smallness? 

Yes. 

Then the one, if of such a nature, has greatness and smallness? 

That appears to be true. 

And greatness and smallness always stand apart? 

True. 

Then there is always something between them? 

There is . 

And can you think of anything else which is between them other 
than equality? 

No, it is equality which lies between them. 

Then that which has greatness and smallness also has equality, which 
lies between them? 

That is clear. 

Then the one, which is not, partakes, as would appear, of 
greatness and smallness and equality? 

Clearly. 

Further, it must surely in a sort partake of being? 

How so? 

It must be so, for if not, then we should not speak the truth in 
saying that the one is not. But if we speak the truth, clearly we must 
say what is. Am I not right? 

Yes. 

And since we affirm that we speak truly, we must also affirm that we 
say what is? 

Certainly . 

Then, as would appear, the one, when it is not, is; for if it were 
not to be when it is not, but were to relinquish something of being, 



so as to become not-being, it would at once be. 

Quite true. 

Then the one which is not, if it is to maintain itself, must have 
the being of not-being as the bond of not-being, just as being must 
have as a bond the not-being of not-being in order to perfect its 
own being; for the truest assertion of the being of being and of the 
not-being of not being is when being partakes of the being of being, 
and not of the being of not-being-that is, the perfection of being; 
and when not-being does not partake of the not-being of not-being 
but of the being of not-being-that is the perfection of not-being. 

Most true. 

Since then what is partakes of not-being, and what is not of 
being, must not the one also partake of being in order not to be? 

Certainly . 

Then the one, if it is not, clearly has being? 

Clearly. 

And has not-being also, if it is not? 

Of course. 

But can anything which is in a certain state not be in that state 
without changing? 

Impossible . 

Then everything which is and is not in a certain state, implies 
change? 

Certainly . 

And change is motion-we may say that? 

Yes, motion. 

And the one has been proved both to be and not to be? 

Yes. 

And therefore is and is not in the same state? 

Yes. 

Thus the one that is not has been shown to have motion also, because 
it changes from being to not-being? 

That appears to be true. 

But surely if it is nowhere among what is, as is the fact, since 
it is not, it cannot change from one place to another? 

Impossible . 

Then it cannot move by changing place? 

No. 

Nor can it turn on the same spot, for it nowhere touches the same, 
for the same is, and that which is not cannot be reckoned among things 
that are? 

It cannot. 

Then the one, if it is not, cannot turn in that in which it is not? 

No. 

Neither can the one, whether it is or is not, be altered into 
other than itself, for if it altered and became different from itself, 
then we could not be still speaking of the one, but of something else? 

True. 

But if the one neither suffers alteration, nor turns round in the 
same place, nor changes place, can it still be capable of motion? 

Impossible . 

Now that which is unmoved must surely be at rest, and that which 
is at rest must stand still? 

Certainly . 

Then the one that is not, stands still, and is also in motion? 

That seems to be true. 

But if it be in motion it must necessarily undergo alteration, for 
anything which is moved, in so far as it is moved, is no longer in the 
same state, but in another? 

Yes. 

Then the one, being moved, is altered? 

Yes. 

And, further, if not moved in any way, it will not be altered in any 
way? 



No. 

Then, in so far as the one that is not is moved, it is altered, 
but in so far as it is not moved, it is not altered? 

Right. 

Then the one that is not is altered and is not altered? 

That is clear. 

And must not that which is altered become other than it previously 
was, and lose its former state and be destroyed; but that which is not 
altered can neither come into being nor be destroyed? 

Very true. 

And the one that is not, being altered, becomes and is destroyed; 
and not being altered, neither becomes nor is destroyed; and so the 
one that is not becomes and is destroyed, and neither becomes nor is 
destroyed? 

True. 

And now, let us go back once more to the beginning, and see 
whether these or some other consequences will follow. 

Let us do as you say. 

If one is not, we ask what will happen in respect of one? That is 
the question. 

Yes. 

Do not the words "is not" signify absence of being in that to 
which we apply them? 

Just so. 

And when we say that a thing is not, do we mean that it is not in 
one way but is in another? or do we mean, absolutely, that what is not 
has in no sort or way or kind participation of being? 

Quite absolutely. 

Then, that which is not cannot be, or in any way participate in 
being? 

It cannot. 

And did we not mean by becoming, and being destroyed, the assumption 
of being and the loss of being? 

Nothing else. 

And can that which has no participation in being, either assume or 
lose being? 

Impossible . 

The one then, since it in no way is, cannot have or lose or assume 
being in any way? 

True. 

Then the one that is not, since it in no way partakes of being, 
neither nor becomes? 

No. 

Then it is not altered at all; for if it were it would become and be 
destroyed? 

True. 

But if it be not altered it cannot be moved? 

Certainly not. 

Nor can we say that it stands, if it is nowhere; for that which 
stands must always be in one and the same spot? 

Of course. 

Then we must say that the one which is not never stands still and 
never moves? 

Neither . 

Nor is there any existing thing which can be attributed to it; for 
if there had been, it would partake of being? 

That is clear. 

And therefore neither smallness, nor greatness, nor equality, can be 
attributed to it? 

No. 

Nor yet likeness nor difference, either in relation to itself or 
to others? 

Clearly not. 



Well, and if nothing should be attributed to it, can other things be 
attributed to it? 

Certainly not. 

And therefore other things can neither be like or unlike, the 
same, or different in relation to it? 

They cannot . 

Nor can what is not, be anything, or be this thing, or be related to 
or the attribute of this or that or other, or be past, present, or 
future. Nor can knowledge, or opinion, or perception, or expression, 
or name, or any other thing that is, have any concern with it? 

No. 

Then the one that is not has no condition of any kind? 

Such appears to be the conclusion. 

Yet once more; if one is not, what becomes of the others? Let us 
determine that. 

Yes; let us determine that. 

The others must surely be; for if they, like the one, were not, we 
could not be now speaking of them. 

True. 

But to speak of the others implies dif f erence-the terms "other" 
and "different" are synonymous? 

True. 

Other means other than other, and different, different from the 
different? 

Yes. 

Then, if there are to be others, there is something than which 
they will be other? 

Certainly . 

And what can that be?-for if the one is not, they will not be 
other than the one. 

They will not. 

Then they will be other than each other; for the only remaining 
alternative is that they are other than nothing. 

True. 

And they are each other than one another, as being plural and not 
singular; for if one is not, they cannot be singular but every 
particle of them is infinite in number; and even if a person takes 
that which appears to be the smallest fraction, this, which seemed 
one, in a moment evanesces into many, as in a dream, and from being 
the smallest becomes very great, in comparison with the fractions into 
which it is split up? 

Very true. 

And in such particles the others will be other than one another, 
if others are, and the one is not? 

Exactly. 

And will there not be many particles, each appearing to be one, 
but not being one, if one is not? 

True. 

And it would seem that number can be predicated of them if each of 
them appears to be one, though it is really many? 

It can. 

And there will seem to be odd and even among them, which will also 
have no reality, if one is not? 

Yes. 

And there will appear to be a least among them; and even this will 
seem large and manifold in comparison with the many small fractions 
which are contained in it? 

Certainly . 

And each particle will be imagined to be equal to the many and 
little; for it could not have appeared to pass from the greater to the 
less without having appeared to arrive at the middle; and thus would 
arise the appearance of equality. 

Yes. 

And having neither beginning, middle, nor end, each separate 



particle yet appears to have a limit in relation to itself and other. 

How so? 

Because, when a person conceives of any one of these as such, 
prior to the beginning another beginning appears, and there is another 
end, remaining after the end, and in the middle truer middles within 
but smaller, because no unity can be conceived of any of them, since 
the one is not. 

Very true. 

And so all being, whatever we think of, must be broken up into 
fractions, for a particle will have to be conceived of without unity? 

Certainly . 

And such being when seen indistinctly and at a distance, appears 
to be one; but when seen near and with keen intellect, every single 
thing appears to be infinite, since it is deprived of the one, which 
is not? 

Nothing more certain. 

Then each of the others must appear to be infinite and finite, and 
one and many, if others than the one exist and not the one. 

They must. 

Then will they not appear to be like and unlike? 

In what way? 

Just as in a picture things appear to be all one to a person 
standing at a distance, and to be in the same state and alike? 

True. 

But when you approach them, they appear to be many and different; 
and because of the appearance of the difference, different in kind 
from, and unlike, themselves? 

True. 

And so must the particles appear to be like and unlike themselves 
and each other. 

Certainly . 

And must they not be the same and yet different from one another, 
and in contact with themselves, although they are separated, and 
having every sort of motion, and every sort of rest, and becoming 
and being destroyed, and in neither state, and the like, all which 
things may be easily enumerated, if the one is not and the many are? 

Most true. 

Once more, let us go back to the beginning, and ask if the one is 
not, and the others of the one are, what will follow. 

Let us ask that question. 

In the first place, the others will not be one? 

Impossible . 

Nor will they be many; for if they were many one would be 
contained in them. But if no one of them is one, all of them are 
nought, and therefore they will not be many. 

True. 

If there be no one in the others, the others are neither many nor 
one . 

They are not. 

Nor do they appear either as one or many. 

Why not? 

Because the others have no sort or manner or way of communion with 
any sort of not-being, nor can anything which is not, be connected 
with any of the others; for that which is not has no parts. 

True. 

Nor is there an opinion or any appearance of not-being in connection 
with the others, nor is not-being ever in any way attributed to the 
others . 

No. 

Then if one is not, the others neither are, nor any of the others 
either as one or many; for you cannot conceive the many without the 
one . 

You cannot . 



Then if one is not, there is no conception of can be conceived to be 
either one or many? 

It would seem not. 

Nor as like or unlike? 

No. 

Nor as the same or different, nor in contact or separation, nor in 
any of those states which we enumerated as appearing to be; -the others 
neither are nor appear to be any of these, if one is not? 

True. 

Then may we not sum up the argument in a word and say truly: If 
one is not, then nothing is? 

Certainly . 

Let thus much be said; and further let us affirm what seems to be 
the truth, that, whether one is or is not, one and the others in 
relation to themselves and one another, all of them, in every way, are 
and are not, and appear to be and appear not to be. 

Most true. 



-THE END-
