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 truth [is in his paintings].. .When they have a similar structure to and are organized in as truthful a way as nature. When I look out of the window, then truth for me is the way nature shows itself in its various tones, colours and proportions. That's a truth and has its own correctness. This little slice of nature, and in fact any given piece of nature, represents to me an ongoing challenge, and is a model for my paintings.

I began in 1976, with small abstract paintings that allowed me to do what I had never let myself do: put something down at random. And then, of course, I realized that it never can be random. It was all a way of opening a door for me. If I don't know what's coming – that is, if I have no hard-and-fast image, as I have with a photographic original – then arbitrary choice and chance play an important part.
