The United Nations is our conscience. If it succeeds it is our success. If it fails it is our failure.

Halfway through any work, one is often tempted to go off on a tangent. Once you have yielded, you will be tempted to yield again and again... Finally, you would only produce something hybrid.

My left hand is my thinking hand (image), my right hand my doing hand (sequence).

My works are an imitation of my own past and present.

I must always have a clear image of the form of a work before I begin. Otherwise there is no impulse to create.

I felt the most intense pleasure in piercing the stone in order to make an abstract form and space; quite a different sensation from that of doing it for the purpose of realism.

My left hand is my thinking hand. The right is only a motor hand. This holds the hammer. The left hand, the thinking hand, must be relaxed, sensitive. The rhythms of thought pass through the fingers and grip of this hand into the stone.
