As a matter of fact, it was only through the dealer Fred Jahn that I succeeded in overcoming my reservation about the works on paper and exhibiting them. Added to this, of course, was the fact that after ten years I could see the watercolours in a different light, and in conjunction with pictures painted afterwards, they had at least become more comprehensible to me.

The photograph is the most perfect picture. It does not change; it is absolute, and therefore autonomous, unconditional, devoid of style. Both in its way of informing, and in what it informs of, it is my source.

If the abstract paintings show my reality, then the landscapes and still-lifes show my yearning.

Contact with like-minded painters - a group means a great deal to me: nothing comes in isolation. We have worked out our ideas largely by talking them through. Shutting myself away in the country, for instance, would do nothing for me. One depends on one's surroundings. And so the exchange with other artists - and especially the collaboration with Lueg and Polke - matters a lot to me: it is part of the input that I need.

I see the bomber pictures as an anti-war statement... which they aren't - at all. Pictures like that don't do anything to combat war. They only show one tiny aspect of the subject of war - maybe only my own childish feelings of fear and fascination with war and with weapons of that kind.

Politicians are nauseating by definition... They can produce nothing, neither a loaf of bread nor a table nor a picture; and this inability to create value, this total inferiority, makes them jealous, vengeful, insolent and a menace to life and limb.

Painting is traditional but for me that doesn't mean the academy. I felt a need to paint; I love painting. It was something natural - as is listening to music or playing an instrument for some people. For this reason I searched for themes of my era and my generation. Photography offered this, so I chose it as a medium for painting.
