I see 30 to 40 gallery shows a week, and no matter what kind of mood I'm in, no matter how bad the art is, I almost always feel better afterward. I can learn as much from bad art as from good.

Pictures artists staged their own images or copied or cut out others already in existence. The viewer took them in separately, in sometimes paradoxical waves: an original image, then the manipulations of it, then the places where image and idea intersected. This created a crucial perceptual glitch that irony and understanding filled.

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?

The secret of food lies in memory - of thinking and then knowing what the taste of cinnamon or steak is.

Yes, 85 percent of the art you see isn't any good. But everyone has a different opinion about which 85 percent is bad. That in turn creates fantastically unstable interplay and argument.

The art world is molting - some would say melting. Galleries are closing; museums are scaling back.

When museums are built these days, architects, directors, and trustees seem most concerned about social space: places to have parties, eat dinner, wine-and-dine donors. Sure, these are important these days - museums have to bring in money - but they gobble up space and push the art itself far away from the entrance.
