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? I do. And that by greatness only great things become great and greater greater, and by smallness the less become less? True. 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.
