It is human nature to want to exchange ideas, and I believe that, at bottom, every artist wants no more than to tell the world what he has to say.

To tell you the truth, I am rather perplexed by the concept of 'art'. What one person considers to be 'art' is often not 'art' to another. 'Beautiful' and 'ugly' are old-fashioned concepts that are seldom applied these days; perhaps justifiably, who knows? Something repulsive, which gives you a moral hangover, and hurts your ears or eyes, may well be art. Only 'kitsch' is not art - we're all agreed about that. Indeed, but what is 'kitsch'? If only I knew!

We adore chaos because we love to produce order.

So let us then try to climb the mountain, not by stepping on what is below us, but to pull us up at what is above us, for my part at the stars; amen.

He who wonders discovers that this in itself is wonder.

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

Although I am even now still a layman in the area of mathematics, and although I lack theoretical knowledge, the mathematicians, and in particular the crystallographers, have had considerable influence on my work of the last twenty years. The laws of the phenomena around us--order, regularity, cyclical repetition, and renewals--have assumed greater and greater importance for me. The awareness of their presence gives me peace and provides me with support. 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.
