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.

Don’t go to a museum with a destination. Museums are wormholes to other worlds. There are ecstasy machines. Follow your eyes to wherever they lead you, stop, get very quiet, and the world should begin to change for you. And if you see me, say something! We can talk about it together.

Abstraction brings the world into more complex, variable relations; it can extract beauty, alternative topographies, ugliness, and intense actualities from seeming nothingness.

The forties, seventies, and the nineties, when money was scarce, were great periods, when the art world retracted but it was also reborn.

Summer is a great time to visit art museums, which offer the refreshing rinse of swimming pools - only instead of cool water, you immerse yourself in art.

New York being what it is, our museums are vertical, not horizontal. That means the stumbling blocks to architectural clarity are unavoidable - but certainly surmountable.

Many things happened in the sixties, but the period is no more significant, better, or more 'political' than today. It's time to turn the page.
