The first biography I read — I think the first scientific biography — was Madame Curie . And my mother, who was a surgeon, worked at the Marie Curie Hospital. She’d met Marie Curie, who was one of her great heroines. And reading the book, I think, was the first portrait of a scientist and the romance of a scientific life.

It was probably a series of biographies of scientists like Pasteur, or even earlier ones — Leeuwenhoek inventing the microscope and Madame Curie. I forget how many others, but it was really just, for me, a fascination to learn about these great heroes. At that time, of course, they were totally inaccessible, almost non-human, to me. It became very interesting to me.

I think fiction is very important because it gets us into the mind of a person. Hamlet is a tremendous piece of literature. You know Hamlet better than you know most real people. Do you know the reason? Because you know what he’s thinking. And this teaches you that every human has an integrity and an autonomy and a spirituality of his own, of her own, and great literature can teach you that.

When I was a young boy, [my schoolteacher Julia Coleman] introduced me to Leo Tolstoy's novel, "War and Peace." She interpreted that powerful narrative as a reminder that the simple human attributes of goodness and truth can overcome great power. She also taught us that an individual is not swept along on a tide of inevitability but can influence even the greatest human events.
