He who wonders discovers that this in itself is wonderful. - M. C. Escher

There is something in such laws that takes the breath away. They are not discoveries or inventions of the human mind, but exist independently of us. In a moment of clarity, one can at most discover that they are there and take them into account. Long before there were people on the earth, crystals were already growing in the earth's crust. On one day or another, a human being first came across such a sparkling morsel of regularity lying on the ground or hit one with his stone tool and it broke off and fell at his feet, and he picked it up and regarded it in his open hand, and he was amazed.

It may seem paradoxical to say that there are similarities between a poetical and a commercial mind, but it is a fact that both a poet and a businessman are constantly dealing with problems that are directly related to people and for which sensitivity is of prime importance. The business-like mind is sometimes described as being cold, sober, calculating, hard; but perhaps these are simply qualities that are necessary for dealing with people if one wants to achieve anything. One is always concerned with the mysterious, incalculable, dark, hidden aspects for which there is no easy formula, but which form essentially the same human element as that which inspires the poet.

version in original Dutch (origineel citaat van M.C. Escher, in het Nederlands): 'Nu wou ik je nog wat zeggen over het verband met muziek, en wel in hoofdzaak met die van Bach, d.w.z. de Fuga, of eenvoudiger canon.. .Het heeft heel veel van mijn motieven, die ik ook om verschillende assen laat draaien. Ik heb dat gevoel van relatie, verwantschap, tegenwoordig zoo sterk, dat ik tijdens het luisteren naar Bach, dikwijls geïnspireerd word en een sterke drang naar zijn dwingende ritme voel, een cadans die iets van de eindeloosheid zoekt. In de Fuga is alles gebaseerd op een enkel motief, dikwijls maar van enkele noten. Bij mij draait ook alles om een enkele gesloten contour..
