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.

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.

I always work out of uncertainty but when a painting's finished it becomes a fixed idea, apparently a final statement. In time though, uncertainty returns.. your thought process goes on.

You dig in and you find something.

There's a market for art, and things are indeed going swimmingly, especially for German artists. But everything takes place in America and in London, where there are quite a few wealthy, engaged people. What motivates them to buy art is a different question, but they do.

I did not always trust my teachers, because I found them too weak. I was looking for something that could take me in a new direction, for things that I could admire. And because it was so hard to find this, I became a sort of outsider. That's why I began to identify with the insane, "outsider" artists.

I had always loved expressionist painting, like every European. In fact I admired it all the more because these were precisely the paintings despised by my father's generation.
