The smudging makes the paintings a bit more complete. When they're not blurred, so many details seem wrong, and the whole thing is wrong too. Then smudging can help make the painting invincible, surreal, more enigmatic - that's how easy it is.

A work of art is itself an object, first of all, and so manipulation is unavoidable: it's a prerequisite. But I needed the greater objectivity of the photograph in order to correct my own way of seeing: for instance, if I draw an object from nature, I start to stylize and to change it in accordance with my personal vision and my training. But if I paint from a photograph, I can forget all the criteria that I get from these sources. I can paint against my will, as it were. And that, to me, felt like an enrichment.

Art should be serious, not a joke. I dont like to laugh about art.

The photograph is the most perfect picture. It does not change; it is absolute, and therefore autonomous, unconditional, devoid of style. Both in its way of informing, and in what it informs of, it is my source.

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 like everything that has no style: dictionaries, photographs, nature, myself and my paintings. (Because style is violent, and I am not violent.)

Now there are no priests or philosophers left, artists are the most important people in the world.
