“Fortunately, a sculptor's style and aim are, to a great extent, dictated to him by his materials. To make a sculpture seem at all moving or inspiring, an artist must, of course, be gifted with a certain personality that speaks movingly through the subject and materials of his work. But he must select appropriate materials, and use them appropriately, too.. .My materials often dictate my change of aims, and I choose to work in a different material much as a man may suddenly feel an appetite for a change in diet. [c. 1960]”
