I work with nature, although in completely new terms.

Focusing isn't just an optical activity; it is also a mental one.

I used to build up to sensation, accumulating tension until it released a perceptual experience

I never make studies from nature. They would get in the way. I make use of my mind.

For me nature is not landscape, but the dynamism of visual forces, an event rather than an appearance. These forces can only be tackled by treating color and form as ultimate identities, freeing them from all descriptive or functional roles.

In my earlier paintings, I wanted the space between the picture plane and the spectator to be active.

I couldn’t get near what I wanted through seeing, recognizing and recreating, so I stood the problem on its head. I started studying squares, rectangles, triangles and the sensations they give rise to It is untrue that my work depends on any literary impulse or has any illustrative intention. The marks on the canvas are sole and essential agents in a series of relationships which form the structure of the painting.
