In a place like the Guggenheim, I would like to be a representative of arte povera. This would be my ideal.

I've painted, but I've also done graphics since as long as I can remember. So even people with little to spend could afford it. But even the graphic works are only bought by those who buy the big, expensive paintings. I think that's troublesome.

I do not have a philosophy about retrospectives. Of course, I cannot change what I have done. What I am doing today, this I can change, in view of whatever I have done before. My retrospectives are like a series of ghosts.

When Michael Werner saw a painting of mine, such as Die grosse Nacht im Eimer, which back then nobody wanted and everybody thought was ridiculous, he realized that this was the right provocation, that it represented the feeling of the times in the right way.

Unlike the expressionists, I have never been interested in renewing the world through the vehicle of art.

I don't paint over my paintings with black paint. I paint black paintings. It isn't because I'm sad, just as I didn't paint red paintings yesterday because I was happy. Nor will I paint yellow paintings tomorrow because I'm jealous.

I always feel attacked when I'm asked about my painting.
