Art is not and never has been subordinate to moral values. Moral values are social values; aesthetic values are human values. Morality seeks to restrain the feelings; art seeks to define them by externalizing them, by giving them significant form. Morality has only one aim - the ideal good; art has quite another aim - the objective truth... art never changes.
