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.

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.

... landscapes or still-lifes I paint in between the abstract works; they constitute about one-tenth of my production. On the one hand they are useful, because I like to work from nature - although I do use a photograph - because I think that any detail from nature has a logic I would like to see in abstraction as well.

As far as the surface is concerned - oil on canvas, conventionally applied - my pictures have little to do with the original photograph. They are totally painting (whatever that may mean). On the other hand, they are so like the photograph that the thing that distinguished the photograph from all other pictures remains intact.

Maybe we didn't even have a chance. The message of American Pop Art was so powerful and so optimistic. But it was also very limited, and that led us to believe that we could somehow distance ourselves from it and communicate a different intention.

The urge to break with a tradition is only appropriate when you're dealing with an outdated, troublesome tradition: I never really thought about that because I take the old-fashioned approach of equating tradition with value (which may be a failing).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.

The desire to please is maligned, unfairly. There are many sides to it. First of all, pictures have to arouse interest before people will even look at them, and then they have to show something that holds that interst - and naturally they have to be presentable, just as a song has to be sung well, otherwise people run away. One mustn't underrate this quality, and I have always been delighted when my pieces have also appealed to the museum guards, the laymen.
