The writer isn't made in a vacuum. Writers are witnesses. The reason we need writers is because we need witnesses to this terrifying century.

From my undergraduate days, I've always been interested in the major philosophical questions that don't seem to have an answer that everyone agrees on.

There are two books that impressed me when I was very young. One was 'The Adventures of Augie March' - the idea of having something so generous, and so adventurous and improvisatory. The other was 'The U.S.A. Trilogy,' by John Dos Passos.

I started on computers with 'Billy Bathgate,' a little orange screen with black letters. I thought it was really cool, but it actually slowed me up for a while because it's so easy to revise, I tended to stay on the same page. I've learned to discipline myself.

I discovered Einstein said the same thing about his celebrated theories of relativity that writers say about their work when he said he didn't have any feelings of personal possession of these ideas. Once they were out there, they came from somewhere else. And that's exactly the feeling when you write. You don't feel possessive about it.
