The Confessions And Letters Of St by St. Augustine
Chapter XIII.--Love Originates from Grace and Beauty Enticing Us.
20. These things I knew not at that time, and I loved these lower beauties, and I was sinking to the very depths; and I said to my friends, |Do we love anything but the beautiful? What, then, is the beautiful? And what is beauty? What is it that allures and unites us to the things we love; for unless there were a grace and beauty in them, they could by no means attract us to them?| And I marked and perceived that in bodies themselves there was a beauty from their forming a kind of whole, and another from mutual fitness, as one part of the body with its whole, or a shoe with a foot, and so on. And this consideration sprang up in my mind out of the recesses of my heart, and I wrote books (two or three, I think) |on the fair and fit.| Thou knowest, O Lord, for it has escaped me; for I have them not, but they have strayed from me, I know not how.
