Art has nothing to do directly with morality or immorality. It is its own excuse for being; it exists for itself. The artist who endeavors to enforce a lesson, becomes a preacher; and the artist who tries by hint and suggestion to enforce the immoral, becomes a pander. There is an infinite difference between the nude and the naked, between the natural and the undressed. In the presence of the pure, unconscious nude, nothing can be more contemptible than those forms in which are the hints and suggestions of drapery, the pretence of exposure, and the failure to conceal. The undressed is vulgar--the nude is pure. The old Greek statues, frankly, proudly nude, whose free and perfect limbs have never known the sacrilege of clothes, were and are as free from taint, as pure, as stainless, as the image of the morning star trembling in a drop of perfumed dew. Morality is the harmony between act and circumstance. It is the melody of conduct. A wonderful statue is the melody of proportion. A great picture is the melody of form and color. A great statue does not suggest labor; it seems to have been created as a joy. A great painting suggests no weariness and no effort; the greater, the easier it seems. So a great and splendid life seems to have been without effort. There is in it no idea of obligation, no idea of responsibility or of duty. The idea of duty changes to a kind of drudgery that which should be, in the perfect man, a perfect pleasure. The artist, working simply for the sake of enforcing a moral, becomes a laborer. The freedom of genius is lost, and the artist is absorbed in the citizen. The soul of the real artist should be moved by this melody of proportion as the body is unconsciously swayed by the rhythm of a symphony. No one can imagine that the great men who chiseled the statues of antiquity intended to teach the youth of Greece to be obedient to their parents. We cannot believe that Michael Angelo painted his grotesque and somewhat vulgar "Day of Judgment" for the purpose of reforming Italian thieves. The subject was in all probability selected by his employeer, and the treatment was a question of art, without the slightest reference to the moral effect, even upon priests. We are perfectly certain that Corot painted those infinitely poetic landscapes, those cottages, those sad poplars, those leafless vines on weather-tinted walls, those quiet pools, those contented cattle, those fields flecked with light, over which bend the skies, tender as the breast of a mother, without once thinking of the ten commandments. There is the same difference between moral art and the product of true genius, that there is between prudery and virtue.
