Camille Paglia

It's high time for the art world to admit that the avant-garde is dead. It was killed by my hero, Andy Warhol, who incorporated into his art all the gaudy commercial imagery of capitalism (like Campbell's soup cans) that most artists had stubbornly scorned.

We live in a crazily youth-orientated world nowadays. It's a trickle-down thing. We see pictures of lithe, attractive celebrity couples such as Brad and Angelina or the Beckhams cavorting around, covered in tattoos, stomachs as flat as the singing in early 'X Factor' rounds.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
