Painting is, I think, inevitably an archaic activity and one that depends on spiritual values.

An artist's early work is inevitably made up of a mixture of tendencies and interests, some of which are compatible and some of which are in conflict

Painting is a science pursued as an enquiry into the laws of nature...Observation is considered the key to natural science.

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.

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

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

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