Being critical of art is a way of showing art respect.

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

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.

I don't know much about auctions. I sometimes go to previews and see art sardined into ugly rooms. I've gawked at the gaudy prices, and gaped at well-clad crowds of happy white people conspicuously spending hundreds of millions of dollars.

Appropriation is the idea that ate the art world. Go to any Chelsea gallery or international biennial and you'll find it. It's there in paintings of photographs, photographs of advertising, sculpture with ready-made objects, videos using already-existing film.

Anyone who relishes art should love the extraordinary diversity and psychic magic of our art galleries. There's likely more combined square footage for the showing of art on one New York block - West 24th Street between Tenth and Eleventh Avenues - than in all of Amsterdam's or Hamburg's galleries.

There's one Baldessari work I genuinely love and would like to own, maybe because of my Midwestern roots and love of driving alone. 'The backs of all the trucks passed while driving from Los Angeles to Santa Barbara, California, Sunday, 20 January 1963' consists of a grid of 32 small color photographs depicting just what the title says.
