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.

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.'

Of course art world ethics are important. But museums are no purer than any other institution or business. Academics aren't necessarily more high-minded than gallerists.

There's something pleasing about large, well-lit spaces. I love that dealers are willing to take massive chances in order to give this much room to their artists. Most of all, I love that more galleries showing more art gives more artists a shot.

When art wins, everyone wins.

Everyone goes to the same exhibitions and the same parties, stays in the same handful of hotels, eats at the same no-star restaurants, and has almost the same opinions. I adore the art world, but this is copycat behavior in a sphere that prides itself on independent thinking.

Maybe the museum [of Arts and Design ]needs to follow the advice of its acronym and not be afraid to go a little M.A.D.
