Perhaps the Doors, Curtains, Surface Pictures, Panes of Glass, etc. are metaphors of despair, prompted by the dilemma that our sense of sight causes us to apprehend things, but at the same time restricts and partly precludes our apprehension of reality.

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.

As far as the surface is concerned - oil on canvas, conventionally applied - my pictures have little to do with the original photograph. They are totally painting (whatever that may mean). On the other hand, they are so like the photograph that the thing that distinguished the photograph from all other pictures remains intact.

I don't believe in the reality of painting, so I use different styles like clothes: it's a way to disguise myself.

The smudging makes the paintings a bit more complete. When they're not blurred, so many details seem wrong, and the whole thing is wrong too. Then smudging can help make the painting invincible, surreal, more enigmatic - that's how easy it is.

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.

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.
