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.

Pictures are the idea in visual or pictorial form; and the idea has to be legible, both in the individual picture and in the collective context - which presupposes, of course, that words are used to convey information about the idea and the context. However, none of this means that pictures function as illustrations of an idea: ultimately, they are the idea. Nor is the verbal formulation of the idea a translation of the visual: it simply bears a certain resemblance to the meaning of the idea. It is an interpretation, literally a reflection.

Unlike the photography and prints, I never catalogued, kept track of or exhibited the sketches. I sold some occasionally, but never saw myself as a graphic artist. They became more important to me thanks to the exhibition, however, and I realized that these drawings were quite interesting after all.

I do not mistrust reality, of which I know next to nothing, but I am suspicious regarding the image of reality which our senses convey to us, and which is incomplete and limited. Our eyes have developed such as to survive. It is merely coincidence that we can see stars with them, as well.

Art is the highest form of hope.

The truth... When they have a similar structure to and are organized in as truthful a way as nature. When I look out of the window, then truth for me is the way nature shows itself in its various tones, colours and proportions. That's a truth and has its own correctness. This little slice of nature, and in fact any given piece of nature, represents to me an ongoing challenge, and is a model for my paintings.

When I look back on the townscapes now, they do seem to me to recall certain images of the destruction of Dresden during the war.
