Art should be serious, not a joke. I dont like to laugh about art.

Weeks go by, and I dont paint until finally I cant stand it any longer. I get fed up. I almost dont want to talk about it, because I dont want to become self-conscious about it, but perhaps I create these little crises as a kind of a secret strategy to push myself.

In 1981, I think, for the Kunsthalle in Düsseldorf. Before that I designed a mirror room for Kasper König's Westkunst show, but it was never built. All that exists is the design - four mirrors for one room.

I go to the studio every day, but I dont paint every day. I love playing with my architectural models. I love making plans. I could spend my life arranging things.

I was a student, and as such you generally rely on prior models of how to make art, but these were not satisfying. Then I discovered in photos what had been missing in paintings; namely that they make a terrific variety of statements and have great substance. That is what I wanted to convey to paintings and apply to it.

Form is all we have to help us cope with fundamentally chaotic facts and assaults. Formulating something is a great start. I trust form, trust my feeling or capacity to find the right form for something. Even if that is only by being well organized. That too is form.

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.
