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. - M. C. Escher

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.

I was peculiarly moved by the angelic life growing on the ground. I have no idea what sorts of flowers grow there in profusion — I don’t know their names. But I was so moved that I sat down, trying to flatten as few grasses and plants as possible with my clumsy backside... This brought my head quite close to the silent, joyful, exuberant, celestial children of heaven. They are so humble, so quiet, and they do not mind if you observe them, if you think they are beautiful... Nor do they mind if you don’t look at all — they just stand there together all by themselves in the huge stretch of woods and grow and bloom just the same, peacefully, joyfully, and silently. I am absolutely sure that they know nothing of the swinish and filthy behaviour of people in their dirty stinking houses — they know only about heaven.

In my prints I try to show that we live in a beautiful and orderly world and not in a chaos without norms, as we sometimes seem to. My subjects are also often playful. I cannot help mocking all our unwavering certainties. It is, for example, great fun deliberately to confuse two and three dimensions, the plane and space, or to poke fun at gravity. Are you sure that a floor cannot also be a ceiling? Are you absolutely certain that you go up when you walk up a staircase? Can you be definite that it is impossible to eat your cake and have it?
