Although I adore the Italian High Renaissance, I'd rather look at Mannerism. The former is ordered, integrated, otherworldly, and grandiose; it leaves you feeling hungry for something flawed and of-the-flesh.

Auction houses run a rigged game. They know exactly how many people will be bidding on a work and exactly who they are. In a gallery, works of art need only one person who wants to pay for them.

Any negative review you write, they'll say, "Oh, you're being so mean." I think the problem with a lot of criticism is that too many critics either write just description or they write in a Mandarin jargon that only a handful of people can understand, or they write happy criticis - everything is good that they write about. I think that's really not good. I think it's damaged a lot of our critical voices.

Jeffrey Deitch is the Jeff Koons of art dealers. Not because he's the biggest, best, or the richest of his kind. But because in some ways he's the weirdest (which is saying a lot when you're talking about the wonderful, wicked, lovable, and annoying creatures known as art dealers).

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.

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.

I see around 100 shows a month, going from Niketown-size palaces where you feel like yelling, to storefronts in Bushwick. Each has to pay the bills; keep artists happy; and cope with collectors (oy!), curators (ay-yi-yi), critics (woo-hoo!), and occasionally plumbers. That their fiscal life often hangs in the balance only adds to the energy.
