You can't prove Rembrandt is better than Norman Rockwell - although if you actually do prefer Rockwell, I'd say you were shunning complexity, were secretly conservative, and hadn't really looked at either painter's work. Taste is a blood sport.

All great contemporary artists, schooled or not, are essentially self-taught and are de-skilling like crazy. I don't look for skill in art... skill has nothing to do with technical proficiency... I'm interested in people who rethink skill, who redefine or reimagine it: an engineer, say, who builds rockets from rocks.

Everyone goes to the same exhibitions and the same parties, stays in the same handful of hotels, eats at the same no-star restaurants, and has almost the same opinions. I adore the art world, but this is copycat behavior in a sphere that prides itself on independent thinking.

Many say an art dealer running a museum is a 'conflict of interest.' But maybe the art world has lived an artificial or unintentional lie all of these years when it comes to conflicts of interest.

After 1909, Monet drastically enlarged his brushstrokes, disintegrated his images, and broke through the taming constraints and delicacy of Impressionism for good. Nineteen gnarly paintings, starting in 1909 and carrying through his final seventeen years, finish off the notion that Monet went happily ever after into lily-land.

Mission accomplished. The Museum of Modern Art's wide-open, tall-ceilinged, super-reinforced second floor was for all intents and purposes built to accommodate monumental installations and gigantic sculptures, should the need arise. It has arisen.

Works of art often last forever, or nearly so. But exhibitions themselves, especially gallery exhibitions, are like flowers; they bloom and then they die, then exist only as memories, or pressed in magazines and books.
