One must be entirely sensitive to the structure of the material that one is handling. One must yield to it in tiny details of execution, perhaps the handling of the surface or grain, and one must master it as a whole.

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

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 works are an imitation of my own past and present.

Body experience... is the centre of creation.

[My works are] an imitation of my own past and present and of my own creative vitality as I experience them in one particular instant of my emotional and imaginative life. . .
