He proceeded: I know nothing and can understand nothing of any other of those wise causes which are alleged; and if a person says to me that the bloom of colour, or form, or any such thing is a source of beauty, I leave all that, which is only confusing to me, and simply and singly, and perhaps foolishly, hold and am assured in my own mind that nothing makes a thing beautiful but the presence and participation of beauty in whatever way or manner obtained; for as to the manner I am uncertain, but I stoutly contend that by beauty all beautiful things become beautiful. This appears to me to be the safest answer which I can give, either to myself or to another, and to this I cling, in the persuasion that this principle will never be overthrown, and that to myself or to any one who asks the question, I may safely reply, That by beauty beautiful things become beautiful. Do you not agree with me?
And that by greatness only great things become great and greater greater, and by smallness the less become less?
Then if a person were to remark that A is taller by a head than B, and B less by a head than A, you would refuse to admit his statement, and would stoutly contend that what you mean is only that the greater is greater by, and by reason of, greatness, and the less is less only by, and by reason of, smallness; and thus you would avoid the danger of saying that the greater is greater and the less less by the measure of the head, which is the same in both, and would also avoid the monstrous absurdity of supposing that the greater man is greater by reason of the head, which is small. You would be afraid to draw such an inference, would you not?
Indeed, I should, said Cebes, laughing.
In like manner you would be afraid to say that ten exceeded eight by, and by reason of, two; but would say by, and by reason of, number; or you would say that two cubits exceed one cubit not by a half, but by magnitude?-for there is the same liability to error in all these cases.
Very true, he said.
Again, would you not be cautious of affirming that the addition of one to one, or the division of one, is the cause of two? And you would loudly asseverate that you know of no way in which anything comes into existence except by participation in its own proper essence, and consequently, as far as you know, the only cause of two is the participation in duality — this is the way to make two, and the participation in one is the way to make one. You would say: I will let alone puzzles of division and addition — wiser heads than mine may answer them; inexperienced as I am, and ready to start, as the proverb says, at my own shadow, I cannot afford to give up the sure ground of a principle. And if any one assails you there, you would not mind him, or answer him, until you had seen whether the consequences which follow agree with one another or not, and when you are further required to give an explanation of this principle, you would go on to assume a higher principle, and a higher, until you found a resting-place in the best of the higher; but you would not confuse the principle and the consequences in your reasoning, like the Eristics — at least if you wanted to discover real existence. Not that this confusion signifies to them, who never care or think about the matter at all, for they have the wit to be well pleased with themselves however great may be the turmoil of their ideas. But you, if you are a philosopher, will certainly do as I say.
What you say is most true, said Simmias and Cebes, both speaking at once.
ECHECRATES: Yes, Phaedo; and I do not wonder at their assenting. Any one who has the least sense will acknowledge the wonderful clearness of Socrates' reasoning.
PHAEDO: Certainly, Echecrates; and such was the feeling of the whole company at the time.
ECHECRATES: Yes, and equally of ourselves, who were not of the company, and are now listening to your recital. But what followed?
PHAEDO: After all this had been admitted, and they had that ideas exist, and that other things participate in them and derive their names from them, Socrates, if I remember rightly, said: —
This is your way of speaking; and yet when you say that Simmias is greater than Socrates and less than Phaedo, do you not predicate of Simmias both greatness and smallness?
Yes, I do.
