I was interested in all kinds of things, whether it be Avatar, Mad Men, Troy, 300, Battlestar Gallactica, or the poems of Horace and Sappho. I always joke about this to my students, who can't quite wrap their mind around the fact that you can have a Ph.D in classics, but not do that full time. I never wanted to write anything with footnotes for the rest of my life. I always think of what I do as the kind of conversation you'd have with somebody, like a good friend, when you've gone and seen a movie together, and you come home and you start talking about it.

I have nothing but great respect for great scholars. But I was in grad school in the '80s and '90s, at the height of the theory craziness. It had a big part in why I ended up becoming a writer rather than a scholar, because I thought, "I just can't play these games." I was interested in literature because I loved literature, and so much of the theoretical positioning, at that moment 25 years ago, was antagonistic to literature.

You had to go to the library, you had to find the books; you had to find the coded things. When everything's available and everything's okay, what does it become? It becomes shopping. We're shopping all the time, basically, whether for objects, or people. On Manhunt or Grindr, or whatever. It's click to buy.

What if The Odyssey has no more validity or authenticity than one of the other stories that you hear Odysseus telling? Whoever created The Odyssey was incredibly hip to stuff that we think, in our post-modernist, post-structuralist era, we're uncovering for the first time; but we aren't.

You come out of the gate, you've got something new, you're subversive, nobody's ever done it before. But by your fifth novel and your fourth literary prize and your house in the country, can you really claim to be subversive?

The three most written-about subjects of all time are Jesus, the Civil War, and the Titanic.
