Simplicity and order are, if not the principal, then certainly the most important guidelines for human beings in general.

By keenly confronting the enigmas that surround us, and by considering and analyzing the observations that I had made, I ended up in the domain of mathematics. Although I am absolutely without training in the exact sciences, I often seem to have more in common with mathematicians than with my fellow artists.

If I am not mistaken, the word "art" and "artist" did not exist during the Renaissance and before: there were simply architects, sculptors, and painters, practicing a trade.

For me it remains an open question whether [this work] pertains to the realm of mathematics or to that of art.

There is something breathtaking about the basic laws of crystals. They are in no sense a discovery of the human mind; they just "are" - they exist quite independently of us. The most that man can do is become aware, in a moment of clarity, that they are there, and take cognizance of them.

My work is a game, a very serious game.

I am always wandering around in enigmas. There are young people who constantly come to tell me: you, too, are making Op Art. I haven't the slightest idea what that is, Op Art. I've been doing this work for thirty years now.
