It was my family that wanted me to be a teacher. That was safe, you see. To be a painter was terrible.

I was at the Royal Art School. That was a preparatory school specially for art teachers. You see, it was not so much for the development of artists. But we had there terribly stiff training.

And I started with this: I have not painted at all my childhood. In fact, I never painted. But I helped my father who was a house painter and decorative painter. He made stage sets, he made glass paintings, he made everything.

It is not so for art in appreciation because art is concerned with human behavior. And science is concerned with the behavior of metal or energy. It depends on what the fashion is. Now today it's energy. It's the same soul behind it. The same soul, you see.

When I came from horizontal vertical straight all old stuff then suddenly I go also again in curved lines. And there I submit to changes in the intensity of my hand leading a tool, you see.

I've handled colour as a man should behave. You may conclude that I consider ethics and aesthetics as one.
