The key is what is within the artist. The artist can only paint what she or he is about.

As I say, I as an abstract artist was active politically.

I have never been able to understand the artist whose image never changes.

I like a canvas to breathe and be alive. Be alive is the point. And, as the limitations are something called pigment and canvas, let's see if I can do it.

All my work keeps going like a pendulum; it seems to swing back to something I was involved with earlier, or it moves between horizontality and verticality, circularlity, or a composite of them. For me, I suppose, that change is the only constant.

We get used to a certain kind of colour of form or format, and it's acceptable. And to puncture that is sticking your neck out a bit. And then pretty soon, that's very acceptable.

People were very affected by the war. But it didn't mean you stopped painting unless you were called into the Army; then you just couldn't paint. But otherwise one continued.
