The giant white cube is now impeding rather than enhancing the rhythms of art. It preprograms a viewer's journey, shifts the emphasis from process to product, and lacks individuality and openness. It's not that art should be seen only in rutty bombed-out environments, but it should seem alive.

I love art dealers. In some ways, they're my favorite people in the art world. Really. I love that they put their money where their taste is, create their own aesthetic universes, support artists, employ people, and do all of this while letting us see art for free. Many are visionaries.

When the purse strings tighten up at museums, the institutions usually cut back and cancel shows. That's exactly the wrong reaction. In fact, now is a good time for them to loosen up - a chance to breathe and experiment a little - and go for the juicy solution lurking in their own basements.

Art is a self-replicating force.

I don't often go to curator or artist walk-throughs of exhibitions. For a critic, it feels like cheating. I want to see shows with my own eyes, making my own mistakes, viewing exhibitions the way most of their audience sees them.

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.

Where Cezanne captured and intensified shards of the eternal (every pear far more sharply defined than it could be in life), Monet portrayed the changeability and flux of every moment. 'The Water Lilies' give you a jittery, amorphous sense of a world seen at the speed of light.
