What I could never escape was Germany, and being German.

That was in 1957. And there I found out that Germany is a kind of province. I didn't know anything about expressionism, about the Bauhaus and Dada and surrealism. I was uneducated, so to speak - and everybody else was more or less uneducated, too.

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

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.

In the beginning, the energy involved to create came from my reaction to the work of other artists. The force behind this was aggression. The art that I saw was great, but I had to reject it, because I could not continue in the same direction. So I had to do something entirely different. It had to be so different, so extreme, that those who loved pop art, for instance, hated me. And this was my strength.

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.
