It makes no sense to expect or claim to 'make the invisible visible', or the unknown known, or the unthinkable thinkable. We can draw conclusions about the invisible; we can postulate its existence with relative certainty. But all we can represent is an analogy, which stands for the invisible but is not it.

The political topicality of my October paintings means almost nothing to me, but in many reviews it is the first or only thing that arouses interest, and the response to the pictures varies according to current political circumstance. I find this rather a distraction.

Grey. It makes no statement whatever; it evokes neither feelings nor associations: it is really neither visible nor invisible. Its inconspicuousness gives it the capacity to mediate, to make visible, in a positively illusionistic way, like a photograph. It has the capacity that no other colour has, to make 'nothing' visible.

I'm trying to paint a picture of what I have seen and what moved me, as well as I can. That's all.

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 choose depending on the way I feel; randomly, in other words. When I haven't done anything for a long time, I always start small, on paper.

Not the victims of any specific ideology of the left or of the right, but of the ideological posture as such. This has to do with the everlasting human dilemma in general: to work for a revolution and fail...

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.

The urge to break with a tradition is only appropriate when you're dealing with an outdated, troublesome tradition: I never really thought about that because I take the old-fashioned approach of equating tradition with value (which may be a failing). But whatever the case, positive tradition can also provoke opposition if it's too powerful, too overwhelming, too demanding. That would basically be about the human side of wanting to hold your own.
