The permanence of Greek art is based upon that public appeal. Art is long because it embodies nature, and most of all human nature. Homer has appealed to man, woman and child for thousands of years. His human nature is our human nature despite external differences of every kind. Homer himself was aware of the appeal of nature in art. On the shield of Achilles, he marveled at the field which grew black behind the plowing, a marvel of Homer’s close study of nature as well as an expression of his ideal for art. Nature is a language all can understand and human nature is a language all must and do understand. When lament was made over the body of Patroklos, the elegy of Briseis stirred all, “and thereon the women wailed, in semblance for Patroklos, but each for her own woe.” Similar is the appeal of art where in semblance of something else, each sees what belongs to self. Aristotle in seeking to explain the characteristic pleasure of art ascribes it to _mimesis_ or re-presentation in another medium. Such staging, he says, not only robs the terrifying of its terrors but enables all to understand and reason to the nature of each art product. Such understanding and reasoning mean surely something more than the mere recognition of photographic accuracy and likeness. If we may press the meaning of the Greek word used for reason, the process of art enjoyment is similar to the syllogistic process which involves an appeal to a general statement. The process is one which recognizes the general in a particular case, as the grief of Briseis found an echoing grief in every heart. Whether Aristotle and this interpretation of him is correct or not, it is evident that art must generalize. Art must select, both by choice of the artist and by the limitations of his medium. Art does not photograph, because it has no sensitive plate for its medium. The photographer’s art largely precedes the camera and consists in selecting that pose and that expression, out of many, which is yours. The camera is nature, controlled by mechanism, and is not art. If the photographer or painter or sculptor photographed you in some passing spasm, we should not learn and reason that it was you. The spasm was realism and fact, but it was peculiar and individual; it was not you whom we have known and generalized from experience. In such a case, Aristotle says shrewdly, we might get artistic pleasure from the workmanship or colors, that is, from the medium and the mechanics of art, but we should have no artistic pleasure from the soul and substance of the art product because the product found no prototype in our experience, because we could not define it or generalize it. Art selects. It cannot give everything, and if it would be true, it must give what all may understand; it must give what is generally true, and what is generally true of all men is human nature.
