All art should have a certain mystery and should make demands on the spectator. Giving a sculpture or a drawing too explicit a title takes away part of that mystery so that the spectator moves on to the next object, making no effort to ponder the meaning of what he has just seen. Everyone thinks that he or she looks but they don't really, you know.

There is a right physical size for every idea.

Between beauty of expression and power of expression there is a difference of function. The first aims at pleasing the senses, the second has a spiritual vitality which for me is more moving and goes deeper than the senses.

You must always be open to your luck. You cannot force it, but you can recognize it.

Never think of the surface except as an extension of a volume.

The important thing is somehow to begin.

I'm very grateful that I was too poor to get to art school until I was 21. . . I was old enough when I got there to know how to get something out of it.
