—As for that, Stephen said in polite parenthesis, we are all animals. I also am an animal.
—You are, said Lynch.
—But we are just now in a mental world, Stephen continued. The desire and loathing excited by improper esthetic means are really not esthetic emotions not only because they are kinetic in character but also because they are not more than physical. Our flesh shrinks from what it dreads and responds to the stimulus of what it desires by a purely reflex action of the nervous system. Our eyelid closes before we are aware that the fly is about to enter our eye.
—Not always, said Lynch critically.
—In the same way, said Stephen, your flesh responded to the stimulus of a naked statue, but it was, I say, simply a reflex action of the nerves. Beauty expressed by the artist cannot awaken in us an emotion which is kinetic or a sensation which is purely physical. It awakens, or ought to awaken, or induces, or ought to induce, an esthetic stasis, an ideal pity or an ideal terror, a stasis called forth, prolonged, and at last dissolved by what I call the rhythm of beauty.
—What is that exactly? asked Lynch.
—Rhythm, said Stephen, is the first formal esthetic relation of part to part in any esthetic whole or of an esthetic whole to its part or parts or of any part to the esthetic whole of which it is a part.
—If that is rhythm, said Lynch, let me hear what you call beauty; and, please remember, though I did eat a cake of cowdung once, that I admire only beauty.
Stephen raised his cap as if in greeting. Then, blushing slightly, he laid his hand on Lynch’s thick tweed sleeve.
—We are right, he said, and the others are wrong. To speak of these things and to try to understand their nature and, having understood it, to try slowly and humbly and constantly to express, to press out again, from the gross earth or what it brings forth, from sound and shape and colour which are the prison gates of our soul, an image of the beauty we have come to understand—that is art.
