I tried to take seriously the idea that if you tortured language you might arrive at some new truth. Later it became clear to me that I was retreading ground by fighting the literary battles of the 1950s and 1960s, and that I was actually a bit bored by some of the books I professed to love.

I realized I had a novel on my hands, but didn't know where it was going to go. So I thought, 'I'm going to do everything that you're not supposed to do when you plan a novel; I'm going to step back and let this thing take itself wherever it wants to go, and I'm not going to worry about how things connect until later on.

I'm interested in complexity, in the mathematical sense, as well as the idiomatic sense. The idea of emergence - that it's possible for complex patterns to arise out of many simple interactions - is fascinating.

But it's the particularity of a place, the physical experience of being in a place, that makes it onto the page. That's why I don't just do library research. I very rarely write about somewhere I haven't been.

I'm fascinated by the emergence of a global class. They're highly mobile; they reject the idea of place.

Being in Harlem on the night of Barack Obama's election was extraordinary. It was the best street party I have ever gone to, and it felt like the period of American history which began with slavery had ended that evening.

There's an explosion of Indian fiction of all kinds, from military thrillers to chicklit. I think that's exciting.
