My work is a game, a very serious game.

I might be in the basement. I'll go upstairs and check. We adore chaos because we love to produce order. I don't use drugs; my dreams are frightening enough.

Originality is merely an illusion.

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

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.

The regular division of the plane into congruent figures evoking an association in the observer with a familiar natural object is one of these hobbies or problems...I have embarked on this geometric problem again and again over the years, trying to throw light on different aspects each time. I cannot imagine what my life would be like if this problem had never occurred to me; one might say that I am head over heels in love with it, and I still don't know why.
