I knew what a circle could do. Both eyes focus on it. It stamps itself out, like a dot. This, in turn, causes one's vision to spread, as in a mandala in Tantric art.
Tony Cairo [English abstract sculptor] and I tried to collaborate at several points and it hasn't been successful. As a matter of fact, recently Tony has made sculpture that I have painted. He has to make the sculpture before I can paint it. That means that the form is taking precedence – that the material takes precedence as a form, rather than color establishing the form. It's not going to well but I'm working on it. There's something about color that is so abstract that it is difficult for it to function in conjunction with solid form… Color has properties of weight, density, transparency, and so forth. And when it also has to be compatible with things that have an actual density, a given form, it's very difficult.
All art that is expressive has to be illusionistic. The raw material out of which art is built is not necessarily in itself potent; you must transform it. Contours, tactility, touch, color, intervals, that's all part of the concreteness of art. You have to make the concreteness expressive. That way you don't cater to taste. You resist sentimentality. Things in a picture can't remind you too much of anything else. You have to resist all that.
