The grey is certainly inspired by the photo-paintings, and, of course, it's related to the fact that I think grey is an important colour - the ideal colour for indifference, fence-sitting, keeping quiet, despair. In other words, for states of being and situations that affect one, and for which one would like to find a visual expression.

My pictures are devoid of objects; like objects, they are themselves objects. This means that they are devoid of content, significance or meaning, like objects or trees, animals, people or days, all of which are there without a reason, without a function and without a purpose. This is the quality that counts. Even so, there are good and bad pictures.

Unlike the photography and prints, I never catalogued, kept track of or exhibited the sketches. I sold some occasionally, but never saw myself as a graphic artist. They became more important to me thanks to the exhibition, however, and I realized that these drawings were quite interesting after all.

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.

My paintings are wiser than I am.

The desire to please is maligned, unfairly. There are many sides to it. First of all, pictures have to arouse interest before people will even look at them, and then they have to show something that holds that interst - and naturally they have to be presentable, just as a song has to be sung well, otherwise people run away. One mustn't underrate this quality, and I have always been delighted when my pieces have also appealed to the museum guards, the laymen.

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.
