Roger Scruton discusses Art, Beauty, and Judgment in The American Spectator:
Rejecting Truth, Morals, Values
[...]Here we see another motive for the desire to desecrate. It is a desire to turn aesthetic judgment against itself, so that it no longer seems like a judgment of us. This you see all the time in children -- the delight in disgusting noises, words, allusions, which helps them to distance themselves from that adult world that judges them, and whose authority they wish to deny. That ordinary refuge of children from the burden of adult judgment has become the refuge of adults from their culture. By using art as an instrument of desecration they neutralize its claims: it loses its authority, and becomes a fellow conspirator in the plot against ideals.You aren't the boss of me, man!
