The artist's job is to be a witness to his time in history.

You begin with the possibilities of the material.

The only thing that I could get with chance, and I never was able to use it, was that I would end up with something quite geometric or the spirit that I was interested in, indulging in, was gone.

So that ideas of sort of relaxed symmetry have been something for years that I have been concerned with because I think that symmetry is a neutral shape as opposed to a form of design.
