In my work, I have never had any use for anything that I have known in advance.

Nobody can teach what is inside a person; it has to be discovered for oneself and a way must be found to express it.

One can never know enough. The unknown and its call lies even in what we know.

The qualities that one needs to be a good goalkeeper are exactly the same as to be a good sculptor. In both professions one should have a good relationship with time and space.

Whatever I know how to do, I've already done. Therefore I must always do what I do not know how to do.

Art is that which comes to a man, and stands between himself and an implacable witness - the work.

Boundaries are actually the main factor in space, just as the present, another boundary, is the main factor in time.
