My paintings are wiser than I am.

The truth... 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.

And then the work bears a strong sense of leave-taking for me personally. It ends the work I began in the 1960s (paintings from black-and-white photographs), with a compressed summation that precludes any possible continuation. And so it is a leave-taking from thoughts and feelings of my own on a very basic level. Not that this is a deliberate act, of course; it is a quasi-automatic sequence of disintegration and reformation which I can perceive, as always, only in retrospect.

Painting pictures is simply the official, the daily work, the profession, and in the case of the watercolours I can sooner afford to follow my mood, my spirits.

Of course I constantly despair at my own incapacity, at the impossibility of ever accomplishing anything, of painting a valid, true picture or even knowing what such a thing ought to look like. But then I always have the hope that, if I persevere, it might one day happen. And this hope is nurtured every time something appears, a scattered, partial, initial hint of something which reminds me of what I long for, or which conveys a hint of it – although often enough I have been fooled by a momentary glimpse that then vanishes, leaving behind only the usual thing.

Weeks go by, and I dont paint until finally I cant stand it any longer. I get fed up. I almost dont want to talk about it, because I dont want to become self-conscious about it, but perhaps I create these little crises as a kind of a secret strategy to push myself.

I don't mistrust reality, of which I know next to nothing. I mistrust the picture of reality conveyed to us by our senses, which is imperfect and circumscribed.
