As I see it, all of them - Tachists, Action Painters, Informel artists, and the rest - are only part of an Informel movement that covers a lot of other things as well. I think there's an Informel element in Beuys, as well; but it all began with Duchamp and chance, or with Mondrian, or with the Impressionists. The Informel is the opposite of the constructional quality of classicism - the age of kings, or clearly formed hierarchies.

There is sorrow, but I hope one can see that it is sorrow for the people who died so young and so crazy, for nothing. I have respect for them, but also for their wishes, or for the power of their wishes. Because they tried to change the stupid things in the world.

I believe I am looking for rightness. My work has so much to do with reality that I wanted to have a corresponding rightness. That excludes painting in imitation. In nature everything is always right: the structure is right, the proportions are good, the colours fit the forms. If you imitate that in painting, it becomes false.

I think everybody starts out by seeing a few works of art and wanting to do something like them. You want to understand what you see, what is there, and you try to make a picture out of it. Later you realize that you can't represent reality at all - that what you make represents nothing but itself, and therefore is itself reality.

It can be a work by Mondrian, a piece of music by Schönberg or Mozart, a painting by Leonardo, Barnett Newman or also Jackson Pollock. That's beautiful to me. But also nature. A person can be beautiful as well. And beauty is also defined as 'untouched'. Indeed, that's an ideal: that we humans are untouched and therefore beautiful.

Everything has a reason, including the selection of the photos, which was not arbitrary but appropriate to the period, its highs and lows and my sense of them.

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