When the father dies, he writes, the son becomes his own father and his own son. He looks at is son and sees himself in the face of the boy. He imagines what the boy sees when he looks at him and finds himself becoming his own father. Inexplicably, he is moved by this. It is not just the sight of the boy that moves him, not even the thought of standing inside his father, but what he sees in the boy of his own vanished past. It is a nostalgia for his own life that he feels, perhaps, a memory of his own boyhood as a son to his father.

Surely it is an odd way to spend your life - sitting alone in a room with a pen in your hand, hour after hour, day after day, year after year, struggling to put words on pieces of paper in order to give birth to what does not exist - except in your head. Why on earth would anyone want to do such a thing? The only answer I have ever been able to come up with is: because you have to, because you have no choice.

I think I hate cynicism more than anything else. It's the curse of our age, and I want to avoid it at all costs.

I was born just after the end of World War II, and with my friends in our little suburban backyards in New Jersey, we used to play war a lot. I don't know if boys still play war, they probably do, but we were thrusting ourselves into recent history and we were always fighting either the Nazis or the Japanese.

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.

After something crystallizes, I can write ferociously and write novels in six months, which in the past would have taken me two years.

There is a line from the Marina Tsvetaeva poem I'm so fond of: "In this most Christian of worlds/ All poets are Jews." What she means is that writers and artists are outside the normal flow of daily life, the normal flow of society in general.
