I believe scientists have a duty to share the excitement and pleasure of their work with the general public, and I enjoy the challenge of presenting difficult ideas in an understandable way.
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.
The pleasure that I take in writing gets me interested in writing a poem. It's not a statement about what I think anybody else should be doing. For me, it's an interesting tension between interior and exterior.
I think the writing of literature should give pleasure. What else should it be about? It is not nuclear physics. It actually has to give pleasure or it is worth nothing.
