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

That was a piece I did in 1963 with Konrad Lueg in a department store, in the furniture department. It was announced in some papers as an exhibition opening, but the people who came didn't know that it was to be a sort of Happening. I don't think it is quite right that it has become so famous anyhow. It was just a lot of fun, and the word itself, Capitalist Realism, hit just right. But it wasn't such a big deal.

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.

Painting is traditional but for me that doesn't mean the academy. I felt a need to paint; I love painting. It was something natural - as is listening to music or playing an instrument for some people. For this reason I searched for themes of my era and my generation. Photography offered this, so I chose it as a medium for painting.

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.

To talk about paintings is not only difficult but perhaps pointless too. You can only express in words what words are capable of expressing-- what language can communicate. Painting has nothing to do with that.
