It's art that pushes against psychological and social expectations, that tries to transform decay into something generative, that is replicative in a baroque way, that isn't about progress, and wants to - as Walt Whitman put it - 'contain multitudes.'

My culture-deprived, aspirational mother dragged me once a month from our northern suburb - where the word art never came up - to the Art Institute of Chicago. I hated it.

The New York gallery scene being as incredibly overpopulated and overmoneyed as it is, deep conflicts and contradictions aren't hard to find.

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.

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.

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

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.
