And when you see artists like Donald Judd and so forth being referred to as conceptual, what the hell does that mean? It's a totally meaningless term.

I'm my own worst critic. I mean, I know what's wrong with everything that I've done.

People ask me why I use words and the reason, of course, is that words talk to you. I mean, they're something that are generated inside of you and that you can relate to you.

The words represent ideas first of all. That is something you have to understand. I mean, it is not just an object, but it is an object with a history and it is loaded with all kinds of implications and ideas. They exist in the world in a very special way. So they kind of represent some aspect of the world that we perceive, as do photographs, as do drawings of trees or whatever. And they are not a one to one. They are not the world, but they kind of refer to the world and they also exist in the world.
