When I look at life I try to be as agnostic and unmetaphysical as possible. So I have to admit that, most probably, we do not have a fate. But I think that's something that draws us to novels - that the characters always have a fate. Even if it's a terrible fate, at least they have one.

We think in terms of fate even if we don't believe in it. Even something as trivial as missing the bus - we think: Well, it might be good for something. We always have that thought, no matter how critical we try to be. The idea that everything is always total chance - we're not made for that.

Usually I work out the plot before I start. This time I thought: Writers always talk about not knowing where a book is going - -I want to experience that, too. What I found out is that it's very interesting, but it takes much longer because you have so many false starts. You take wrong turns and you have to go back and start the whole chapter, or the whole section, from scratch.

Exactly as we might ask God, and do ask God, to change our fate. The difference is that in the story the writer actually replies and in the end even changes his mind.

So the fact that there's someone who's planning what happens to the characters, writing it down, means that the characters always have a fate. And when we think about fate, we tend think of it as the thing we would have if we were literary characters, that is, if there were somebody out there, writing us.

I think I can work anywhere, but you don't get the same kind of inspiration everywhere. New York theater has become a big inspiration for me. I only started writing for the stage myself because I like to see the good, mostly off-Broadway plays in New York.

You say fate is almost indispensable to literature - I think it's completely indispensable, at least in a novel, because a novel always has a plot. Even if nothing happens, even if someone just spends a day walking around Dublin, or whatever, there's still something going on.
