Which book changed the way you think, and what did it change?

C. S. Lewis - his works were very, very important during my time there. We had discussion groups. I did become more attracted to it although I still attended the Methodist church. If you read Lewis. Then until this day, he did the lectures, something like christian behaviour and 'the screwtape letters', and we were all discussing them. I thought some of his work was the most illuminating to people reaching out to christianity because you're always questioning particularly at that age and you're looking for reassurance and for answers. Indeed you go on questioning throughout your life.

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.

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.

I’d been introduced to Freud through all this because I couldn’t understand why is it so difficult to be brave. There was something inside me that wanted to collaborate all the time with the people who wanted to destroy me, and I was searching for it, and I found there was a thing called the unconscious that everybody has. And you’ve got to be in touch with the unconscious to understand a lot of your behavior. And I read through volume after volume after volume of the collected works of Sigmund Freud.

The Fountainhead , I think, pretty much saved me in the initial years of Teach For America. I loved that book, but I’m not sure books were the seminal thing that guided my path. ... I think it was sort of about “the creator against the world,” and I was probably feeling at that point that I was up against lots of boulders, to pull off the big idea of Teach For America.

It’s amazing. I just started looking at everything differently. I love that book. But a book is a kind of thing of magic. It contains a universe of information.
