Art history is fine. I mean, that's a discipline. Art history is art history, and you start from the beginning and you end up in artist in time. But art is a little bit different. Art is a conversation. And if there's no conversation, what the hell is it about?

The concept of who your audience is becomes more important than your site. Sometimes you can be commissioned to do a piece in Strasburg, and it works. Sometimes you're commissioned to do a piece somewhere else and it doesn't work, but then it moves to another city, the people embrace it, and becomes part of them. You just misjudged the needs of the people. Art is about giving people material and things to work with to fulfill whatever needs they have.

The art schools seem to be trying to turn people out as "professional." But I don't know what the word "professional" means any longer. "Professional" would be somebody who was trying to push painting to a point that nobody else could do as well as he could. That would be my ideal professional.

Once you know about a work of mine you own it. There's no way I can climb inside somebody's head and remove it.

What interested me the most was that when I [traveled to Europe] I knew what Joseph Beuys was doing, he knew what I was doing, and we both, we just started to talk. How did I know what Daniel Buren was doing, and to an extent, he knew exactly what I was doing? How did everybody know? It's an interesting thing. I'm still fascinated by it because, why is it now, with the Internet and everything else, you get whole groups of artists who have chosen to be regional? They really are only with the people they went to school with.

People, buying my stuff, can take it wherever they go and can rebuild it if they choose. If they keep it in their heads, that's fine too. They don't have to buy it to have it - they can just have it by knowing it.

There are people who speculate at objects. I don't think that makes them evil or not evil. It doesn't matter; in order to speculate, it has to be made public. Once it's made public, it's functioned is art.
