I love Rauschenberg. I love that he created a turning point in visual history, that he redefined the idea of beauty, that he combined painting, sculpture, photography, and everyday life with such gall, and that he was interested in, as he put it, 'the ability to conceive failure as progress.'

Abstraction brings the world into more complex, variable relations it can extract beauty, alternative topographies, ugliness, and intense actualities from seeming nothingness.

All of Koons's best art - the encased vacuum cleaners, the stainless-steel Rabbit (the late-twentieth century's signature work of Simulationist sculpture), the amazing gleaming Balloon Dog, and the cast-iron re-creation of a Civil War mortar exhibited last month at the Armory - has simultaneously flaunted extreme realism, idealism, and fantasy.

The last time money left the art world, intrepid types maxed out their credit cards and opened galleries, and a few of them have become the best in the world.

Those who love him love that he sells the most art they take it as a point of faith that this proves Kinkade is the best. But his fans don't only rely on this supply-and-demand justification. They go back to values.
