The Silent Isle by A.C. Benson

It is such a perennial mystery to me what beauty is; it baffles me entirely. No one has ever helped me to discover in what region of the spirit it abides. The philosopher begins by telling you that the simplest and most elementary form of beauty which appeals to every one, the beauty of human beings, has its root originally only in desire; but I cannot follow that, because that would only account for one's admiring a certain kind of fresh and youthful beauty, and in admiring human beauty less and less as it declines from that. But this is not the case at all; because there is a beauty of age which is often, in its way, a more impressive and noble thing than the beauty of youth.

And there is, too, the beauty of expression, a far more subtle and moving thing than mere beauty of feature: we must have often seen, for instance, a face which by all the canons of beauty might be pronounced admirable, yet the effect of which is wholly unattractive; while, on the other hand, we have known faces that, from some ruggedness or want of proportion, seemed at first sight even repellent, which have yet come to hold for one an extraordinary quality of attractiveness, from the beauty of the soul being somehow revealed in them, and are yet as remote from any sense of desire as the beauty of a tree or a crag.
