The problem that although behaving rightly is supposed to override other goals, nevertheless ethical considerations may justifiably be subservient to other artistic, cultural, or scientific aims. Williams (Moral Luck, 1981) uses the painter Gauguin as a symbol of someone behaving rather badly (at least to his family) for the sake of art, and who is justified in the event by the successes he achieved in that sphere. See also moral luck, piacular.
