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 was always on the outside. It was the worst when I still wanted to be a professor, having to deal with colleagues and students, and having to listen to all that academic nonsense. It's really just a haze that keeps them busy. But all of that is fortunately over now, once and for all.

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.

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.

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

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.

I paint German artists whom I admire. I paint their pictures, their work as painters, and their portraits too. But oddly enough, each of these portraits ends up as a picture of a woman with blonde hair. I myself have never been able to work out why this happens.
