I try in my prints to testify that we live in a beautiful and orderly world, and not in a formless chaos, as it sometimes seems.

The things I want to express are so beautiful and pure.

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

At moments of great enthusiasm it seems to me that no one in the world has ever made something this beautiful and important.

I believe that producing pictures, as I do, is almost solely a question of wanting so very much to do it well.

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

Wonder is the salt of the earth.
