I don't see art as entertainment.

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.

Nowhere in my collection do I, say, have a Auguste Renoir painting. Because everybody knows that this is a good painter without me having to demonstrate it.

I don't like things that can be reproduced. Wood isn't important in itself but rather in the fact that objects made in it are unique, simple, unpretentious.

No one who looks at my paintings can see whether a painting is upside down or not anymore. I've made or developed so many image models that some people have given up trying to keep track of me. But others have only one or two ways of doing things and are successful with that.

Despite all the taxes people pay, there supposedly isn't any money in this country for art. Of course, this makes an artist ask himself: "Well, then, what are you doing with the 100 million I pay each year? What happened to that money?" And he doesn't get an answer.

I have always had the feeling that other people are too stupid to discover interesting things. That's why I do it myself. I think of collecting as a way to show that I understand what's important better than others do.
