I dare say that the simile is not perfect-for I am very far from admitting that he who contemplates existence through the medium of ideas, sees them only "through a glass darkly," any more than he who sees them in their working and effects.
However, this was the method which I adopted: I first assumed some principle which I judged to be the strongest, and then I affirmed as true whatever seemed to agree with this, whether relating to the cause or to anything else; and that which disagreed I regarded as untrue.
But I should like to explain my meaning clearly, as I do not think that you understand me.
No, indeed, replied Cebes, not very well.
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, and I shall have to go back to those familiar words which are in the mouth of everyone, 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, as I readily 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 that if there be anything beautiful other than absolute beauty, that can only be beautiful in as far as it partakes of absolute beauty-and this I should say of everything.
Do you agree in this notion of the cause?
Yes, he said, I agree.
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 color, or form, or anything else of that sort 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.
That appears to me to be the only safe answer that I can give, either to myself or to any other, and to that I cling, in the persuasion that I shall never be overthrown, and that I may safely answer to myself or any other that by beauty beautiful things become beautiful.
Do you not agree to that?
Yes, I agree.
And that by greatness only great things become great and greater greater, and by smallness the less becomes less.
True.
Then if a person remarks that A is taller by a head than B, and B less by a head than A, you would refuse to admit this, 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, or by reason of, smallness; and thus you would avoid the danger of saying that the greater is greater and the 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.
Would you not be afraid of that?
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 that two cubits exceed one cubit not by a half, but by magnitude?-that is what you would say, for there is the same danger in both cases.
Platonic recollection: knowledge as the soul's recovery of what it knew before birth, with learning as remembering rather than acquisition.
The passage describes knowledge as recovering a principle that was always present ('always and everywhere repeating'), aligning with the Platonic concept of recollection.
Describing the divine only by negation—God transcends all positive categories and concepts; the via negativa.
The text explicitly argues against viewing existence through 'a glass darkly' and emphasizes understanding only what agrees with the strongest principle.
Augustinian and Plotinian doctrine that evil has no positive being of its own but is a lack, distortion, or absence of the good — denying ontological dualism while preserving moral seriousness.
The text defines beauty and goodness as absolute principles that make things beautiful, implying that lack of these qualities constitutes deficiency or evil.
Diotima's staged ascent from love of beautiful bodies → beautiful souls → beautiful pursuits → beautiful knowledge → Beauty itself; the canonical scala amoris that grounds Plotinus's On the Beautiful and Bruno's Eroici Furori — distinct from generic spiritual_ascent in that eros is the specific motive force.
The passage outlines a structured ascent from beauty of form to absolute beauty, mirroring the Platonic scala amoris.
The recognition of one's own true divine nature as the primary path to liberation; 'know thyself' as soteriology.
The speaker claims to be 'stoutly contended' in his own mind regarding the nature of beauty and truth, prioritizing personal assurance over external opinion.
The felt condition of exile from one's divine origin — Rumi's reed flute torn from its bed, Plotinus's 'we have forgotten,' the Gnostic forgetfulness; the affective wound that complements return_to_source and gives the return its motive.
The phrase 'contemplates existence through the medium of ideas' implies a current state of distance from the absolute source of beauty.
