No book includes the entire world. It's limited. And so it doesn't seem like an aesthetic compromise to have to do that. There's so much other material to write about.

Memoirs have dominated the literary scene now for ten or 20 or even 30 years: most of them seem to use the conventions of fiction and it's astonishing how in so many of these books people seem to be able to remember conversations that took place when they were five years old and give three pages of coherent dialogue, which is utterly impossible.

History is present in all my novels. And whether I am directly talking about the sociological moment or just immersing my character in the environment, I am very aware of it.

It was a wrong number that started it, the telephone ringing three times in the dead of night, and the voice on the other end asking for someone he was not.

I've dealt with numbers all my life, of course, and after a while you begin to feel that each number has a personality of its own. A twelve is very different from a thirteen, for example. Twelve is upright, conscientious, intelligent, whereas thirteen is a loner, a shady character who won't think twice about breaking the law to get what he wants. Eleven is tough, an outdoorsman who likes tramping through woods and scaling mountains; ten is rather simpleminded, a bland figure who always does what he's told; nine is deep and mystical, a Buddha of contemplation.

We're outsiders, and so when we walk through the city, we're there and not there at the same time, participating and observing simultaneously.

For example, when I was writing Leviathan, which was written both in New York and in Vermont - I think there were two summers in Vermont, in that house I wrote about in Winter Journal, that broken-down house... I was working in an out-building, a kind of shack, a tumble-down, broken-down mess of a place, and I had a green table. I just thought, "Well, is there a way to bring my life into the fiction I'm writing, will it make a difference?" And the fact is, it doesn't make any difference. It was a kind of experiment which couldn't fail.
