I believe that nothing should be taboo - no theory or prejudice should close one's mind to a discovery.
The hole connects one side to the other, making it immediately more three-dimensional. A hole can itself have as much shape-meaning as a solid mass.
There are universal shapes to which everybody is subconsciously conditioned and to which they can respond if their conscious control does not shut them off.
In my opinion, long and intense study of the human figure is the necessary foundation for a sculptor.
A sculptor is a person who is interested in the shape of things, a poet in words, a musician by sounds.
It is a mistake for a sculptor or a painter to speak or write very often about his job. It releases tension needed for his work.
