I have a soft spot for art that, in terms of subject matter and material, is in bad taste.

Poor Georgia O'Keeffe. Death didn't soften the opinions of the art world toward her paintings.

Batty as it sounds, subject and style may choose artists, through some unfathomable cosmic means. How else to explain that even artists who enjoy what they do can be perplexed or even horrified that they're doing it?

I just want to say one thing about the '70s. Enough with this purer, "It was a better time," business. Every time is about as polluted and needy and beautiful as most other times. I was around in the '70s, and people were just as ambitious and envious and filled with need and desire as they are today.

'Summer of Love: Art of the Psychedelic Era,' the Whitney Museum's 40th-anniversary trip down counterculture memory lane, provides moments of buzzy fun, but it'll leave you only comfortably numb. For starters, it may be the whitest, straightest, most conservative show seen in a New York museum since psychedelia was new.

Auction houses run a rigged game. They know exactly how many people will be bidding on a work and exactly who they are. In a gallery, works of art need only one person who wants to pay for them.

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.
