In the beginning I tried to accommodate everything there that was somewhere between art and garbage and that somehow seemed important to me and a pity to throw away. After a while, some sheets in the Atlas acquired another value, after all - that is, it seemed to me that they could stand on their own terms, not only under the protection of the Atlas.

The painter sees the semblance of things and repeats it. That is, without fabricating the things himself, he fabricates their semblance; and, if that no longer recalls any object, this artificially produced semblance functions only because it is scrutinized for likeness to a familiar - that is, object-related - semblance.

Experience has proved that there is no difference between a so-called realist painting - of a landscape, for example - and an abstract painting. They both have more or less the same effect on the observer.

Abstract pictures are fictive models, because they make visible a reality that we can neither see nor describe, but whose existence we can postulate.

The first colour charts were unsystematic. They were based directly on commercial colour samples. They were still related to Pop Art. In the canvases that followed, the colours were chosen arbitrarily and drawn by chance. Then, 180 tones were mixed according to a given system and drawn by chance to make four variations of 180 tones. But after that the number 180 seemed too arbitrary to me, so I developed a system based on a number of rigorously defined tones and proportions.

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

If, while I'm painting, I distort or destroy a motif, it is not a planned or conscious act, but rather it has a different justification: I see the motif, the way I painted it, is somehow ugly or unbearable. Then I try to follow my feelings and make it attractive. And that means a process of painting, changing or destroying - for however long it takes - until I think it has improved. And I don't demand an explanation from myself as to why this is so.
