Nothing to stick your tongue out at

“The struggle against purpose in art is always a struggle against the moralizing tendency in art, against the subordination of art to morality.  L’art pour l’art means : ‘the devil take morality!’—But this very hostility betrays that moral prejudice is still dominant.  When one has excluded from art the purpose of moral preaching and human improvement it by no means follows that art is completely purposeless, goalless, meaningless, in short l’art pour l’art—a snake biting its own tail.  ‘Rather no purpose at all than a moral purpose!’—thus speaks mere passion.  A psychologist asks on the other hand: what does all art do? does it not praise? does it not glorify? does it not select? does it not highlight?  By doing all this it strengthens or weakens certain valuations.” – Friedrich Nietzsche, Twilight of the Idols (trans. Hollingdale; emphases in original)
