As a kid, I was growing up in an era of celebration of the Civil War centennial, with a lot of 'Lost Cause' emphasis on the Confederacy. I used to play Civil War soldiers with my brothers as a child, and my older brother always insisted that he got to be Lee, and I got be Grant. I never knew that Grant won until quite some time had passed.

When I was growing up in Virginia, the Civil War was presented to me as glorious with dramatic courage and military honor. Later, I realized how death was central to the reality. It was at the core of women's lives. It's what they talked about most.

Albert Camus's 'La Peste' - 'The Plague' - had an enormous impact on me when I read it in high school French class, and I chose my senior yearbook quote from it. In college, I wrote a philosophy class paper on Camus and Sartre, and again chose my yearbook quote from 'La Peste.'

I lived in a world where social arrangements were taken for granted and assumed to be timeless. A child's obligation was to learn these usages, not to question them. The complexities of racial deportment were of a piece with learning manners and etiquette more generally.

Science and technology are the keys to both our longevity and our demise. Our entire existence on this planet is a double-edged sword.

The existence is a tremendous curiosity, with in the course of the years, the discovery of yourself in your inmost evolutions. With the age you feel better than you are, what you represent. Which means a little at the planet's scale.

I vowed to myself that when I grew up and became a theoretical physicist, in addition to doing research, I would write books that I would have liked to have read as a child. So whenever I write, I imagine myself, as a youth, reading my books, being thrilled by the incredible advances being made in physics and science.

You are done for - a living dead man - not when you stop loving but stop hating. Hatred preserves: in it, in its chemistry, resides the mystery of life.
