To look is one thing, to see is another thing; to see is very difficult, normally; to look is to try to see. I have looked and I hope I have seen.

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

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

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

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

To look is one thing, to see is another thing; to see is very difficult, normally; to look is to try to see. I have looked and I hope I have seen.

The hand has the richest articulation of space.

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