Plato, Symposium

[211a] and neither comes to be nor perishes, neither waxes nor wanes; next, it is not beautiful in part and in part ugly, nor is it such at such a time and other at another, nor in one respect beautiful and in another ugly, nor so affected by position as to seem beautiful to some and ugly to others. Nor again will our initiate find the beautiful presented to him in the guise of a face or of hands or any other portion of the body, nor as a particular description or piece of knowledge, nor as existing somewhere in another substance, such as an animal or [211b] the earth or sky or any other thing; but existing ever in singularity of form independent by itself, while all the multitude of beautiful things partake of it in such wise that, though all of them are coming to be and perishing, it grows neither greater nor less, and is affected by nothing. So when a man by the right method of boy-loving ascends from these particulars and begins to descry that beauty, he is almost able to lay hold of the final secret. Such is the right approach [211c] or induction to love-matters. Beginning from obvious beauties he must for the sake of that highest beauty be ever climbing aloft, as on the rungs of a ladder, from one to two, and from two to all beautiful bodies; from personal beauty he proceeds to beautiful observances, from observance to beautiful learning, and from learning at last to that particular study which is concerned with the beautiful itself and that alone; so that in the end he comes to know [211d] the very essence of beauty. In that state of life above all others, my dear Socrates,’ said the Mantinean woman, ‘a man finds it truly worth while to live, as he contemplates essential beauty. This, when once beheld, will outshine your gold and your vesture, your beautiful boys and striplings, whose aspect now so astounds you and makes you and many another, at the sight and constant society of your darlings, ready to do without either food or drink if that were any way possible, and only gaze upon them and have their company. [211e] But tell me, what would happen if one of you had the fortune to look upon essential beauty entire, pure and unalloyed; not infected with the flesh and color of humanity, and ever so much more of mortal trash? What if he could behold the divine beauty itself, in its unique form?
