Visible things can be invisible. However, our powers of thought grasp both the visible and the invisible – and I make use of painting to render thoughts visible.

If one looks at a thing with the intention of trying to discover what it means, one ends up no longer seeing the thing itself, but of thinking of the question that is raised.

Each thing we see hides something else we want to see.

We are surrounded by curtains. We only perceive the world behind a curtain of semblance. At the same time, an object needs to be covered in order to be recognized at all.

My investigations resembled the pursuit of the solution to a problem for which I had three data: the object, the thing connected with it in the shadow of my consciousness, and the light wherein that thing would become apparent.

The purpose of art is mystery.

Everything we see hides another thing, we always want to see what is hidden by what we see. There is an interest in that which is hidden and which the visible does not show us. This interest can take the form of a quite intense feeling, a sort of conflict, one might say, between the visible that is hidden and the visible that is present.
