Painting is the making of an analogy for something non-visual and incomprehensible - giving it form and bringing it within reach. And that is why good paintings are incomprehensible. Creating the incomprehensible has absolutely nothing to do with turning out any old bunkum, because bunkum is always comprehensible.

What attracted me about my mirrors was the idea of having nothing manipulated in them. A piece of bought mirror. Just hung there, without any addition, to operate immediately and directly. Even at the risk of being boring. Mere demonstration. The mirrors, and even more the Panes of Glass, were also certainly directed against Duchamp, against his Large Glass.

The Atlas belongs to the Lenbachhaus in Munich - it's long since ceased to belong to me. Occasionally I run across it somewhere, and I think it's interesting because it looks different each time.

But I would like to reach the point where I could cut up an illustrated magazine at random and see to it that the parts would each become a painting. I cannot properly explain it right now. Already now I am searching for the most boring and irrelevant photo material that I can find. And I would like to get to the point soon where this determined irrelevance could be retained, in favor of something that would be covered up otherwise by artifice.

Picturing things, taking a view, is what makes us human; art is making sense and giving shape to that sense. It is like the religious search for God.

I wanted to say something different: the pictures are also a leave-taking, in several respects. Factually: these specific persons are dead; as a general statement, death is leave-taking. And then ideologically: a leave-taking from a specific doctrine of salvation and, beyond that, from the illusion that unacceptable circumstances of life can be changed by this conventional expedient of violent struggle.

When I paint from a photograph, conscious thinking is eliminated. I don't know what I am doing. My work is far closer to the Informel than to any kind of 'realism'. The photograph has an abstraction of its own, which is not easy to see through.
