In art, immorality cannot exist. Art is always sacred even when it takes for a subject the worst excesses of desire; since it has in view only the sincerity of observation, it cannot debase itself. A true work of art is always noble, even when it translates the stirrings of the brute, for at that moment, the artist who has produced it had as his only objective, the most conscientious rendering possible of the impression he has felt.
