In high school I read [Lev] Tolstoy's "Anna Karenina" and loved it. Then I read [Friedrich] Nietzsche's "On the Genealogy of Morals" and that hit me hard. I don't know where I got it. My parents warned me not to mention either of those books when I went for my college interviews so I wouldn't seem like an egghead. They told me to talk about sports.

There's a huge amount of work on Adam and Eve, from the ancient world to the present. Saint Augustine was obsessed with them.I don't know if it helps my research, but I get a big kick out of Mark Twain, who wrote "The Diaries of Adam and Eve." He wrote very funny stuff on them. I sometimes read things that are loosely related to what I'm thinking and writing about.

A couple of years ago I picked up New Yorker writer Alma Guillermoprieto's "The Heart That Bleeds," which is reportage from Latin America in the 1990s. You can predict that some books will give you a thrill, but you can't predict the books that will hit you hard. It is a little bit like falling in love.

I believe that nothing comes of nothing, even in Shakespeare. I wanted to know where he got the matter he was working with and what he did with that matter.

It is not that Shakespeare's art is in technicolor and fancy, and that real life is black and white and tedious. The life that Shakespeare was living was the only life he had, and he had to use it to create what he was doing.

In short, it became possible - never easy, but possible - in the poet Auden's phrase to find the mortal world enough.

First of all, Shakespeare is about pleasure and interest. He was from the first moment he actually wrote something for the stage, and he remains so.
