Artists talk about art in sort of straightforward terms, more like the way you talk about plumbing fixtures. Does it function well? Does it bring the hot water up from the cellar efficiently, or does it lose too much thermodynamic energy in the process? Artists are also very ruthless with each other and can be very brutal in evaluating each other's work because their criteria is almost more mechanistic. Does it do what it's supposed to be doing in an efficient way? That doesn't mean that intention is not part of the conversation, but it's not the foreground.

There were successful ways of expressing the attitude and less successful ways. I think that spirit is very much alive today actually. That's what a certain generation of curators is alert to or on the look out for: an attitude. And it is a brilliant and moving spectacle when it happens. That suspension of disbelief is something that we all respond to. But it's hard to capture the butterfly without tearing the wings off of it.

No one's quite figured out how to make the images come to the viewer. I guess if they put it on a conveyor belt, you could stand in one place like at sushi restaurants. That could be a next generation of museums. Someone should try that. I think ideally you want to have a contemplative space for the viewer. And shuffling around like a chain gang does work against that.

I'm always very grateful for stories about the great coffeehouse wits in Vienna at the turn of the last century. People would wait for a chance to stand near the table where the great wits were trading witticisms as a spectator sport because it was that good. They were that on fire and there was no product. They didn't write anything down. It was just the pleasure of engagement with the moment. I think that's my kind of ideal of how I live.

I do work hard at trying to find the right expression for something, which might be like finding the right image - choosing not only the right words but down to the right number of lines. I remember being in Maine once at Colby College with Alex Katz. It houses hundreds of his works. There was a painting of just one seagull against a blue sky. I was admiring it and Alex said, "45 brush strokes exactly."

If you go to a concert, you will notice, is it loud? Is the music fast? Is it predominately strings or brass? There are things we can all register, whether we are musicians or not. Painting's no different. Taking pleasure in projecting oneself into the painting is the act of looking. That's what looking is.

For me, art history is like a feather bed - you fall into it and it catches you.
