There is nothing new, he said, in what I am about to tell you; but only what I have been always and everywhere repeating in the previous discussion and on other occasions: I want to show you the nature of that cause which has occupied my thoughts. I shall have to go back to those familiar words which are in the mouth of every one, and first of all assume that there is an absolute beauty and goodness and greatness, and the like; grant me this, and I hope to be able to show you the nature of the cause, and to prove the immortality of the soul. Cebes said: You may proceed at once with the proof, for I grant you this. Well, he said, then I should like to know whether you agree with me in the next step; for I cannot help thinking, if there be anything beautiful other than absolute beauty should there be such, that it can be beautiful only in so far as it partakes of absolute beauty—and I should say the same of everything. Do you agree in this notion of the cause? Yes, he said, I agree. [Sidenote: All things exist by participation in general ideas.] 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.
