'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.

Nearly a half-century on from feminism, simply being a woman artist is still a revolutionary act. And getting one's work shown continues to be met by enormous inbuilt resistance.

In the seventies, a group of American artists seized the means not of production but of reproduction. They tore apart visual culture at a time of no money, no market, and no one paying attention except other artists. Vietnam and Watergate had happened; everything in America was being questioned.

Art schools are partly the villain here. (Never mind that I teach in them.) This generation of artists is the first to have been so widely credentialed, and its young members so fetishize the work beloved by their teachers that their work ceases to talk about anything else. Instead of enlarging our view of being human, it contains safe rehashing of received ideas about received ideas. This is a melancholy romance with artistic ruins, homesickness for a bygone era. This yearning may be earnest, but it stunts their work, and by turn the broader culture.

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.

Put yourself in the position of an up-and-coming artist living in early-sixteenth-century Italy. Now imagine trying to distinguish yourself from the other artists living in your town: Michelangelo, Raphael, Leonardo, or Titian. Is it any wonder that the Italian High Renaissance lasted only 30 years?

Artistic qualities that once seemed undeniable don't seem so now. Sometimes these fluctuations are only fickleness of taste, momentary glitches in an artist's work, or an artist getting ahead of his audience (it took me ten years to catch up to Albert Oehlen). Other times, however, these problems mean there's something wrong with the art.
