Many novelists say, "I'm not a political novelist" - myself included. That's a standard, even a default position. Whereas that divide between art and politics simply isn't possible in many countries. In Hungary, you couldn't be a fiction writer and then, when asked about politics, put your hands up in the air and say "But I'm not a political novelist." If you're a Chinese novelist, a novelist in a country where censorship is such an issue, how do you claim that politics has nothing to do with your writing? It's in your writing, it's shaping your words.

There's a perception that good writing is writing which runs smoothly. But smooth-running prose can work against what you're trying to express in a novel.

Fiction always reveals a lot about the person who is writing it. That's the scary thing. Not in a straightforward autobiographical sense. But the flaws in a piece of fiction are, unhappily, so often also the flaws of the writer.

I don't know why I write. The honest answer is that I don't have an answer. I wouldn't die if I couldn't write fiction. Actually keel over and die - it's unlikely. But quite quickly writing has come to feel like the only thing I really know how to do. And I go a bit stir crazy if I don't write more or less every day. But that makes writing sound like a mood-regulator, a way to regulate anxiety or depression, and it doesn't really come down to that.

I can't define myself as a political writer - I don't think I've earned it, and I don't function as a political writer in the way that many of the writers I admire do. It's not simply a question of context, of where I'm writing from - there is much in American society that urgently needs to be written about. I think your work is always engaged with politics in the looser sense of the word - and that looseness is itself a kind of privilege - because politics and culture are evidently intertwined.

Evidently, there are many great American writers. But sometimes it can feel as though American fiction is dominated by relatively linear narrative form, with a heavy emphasis on psychological realism. If you limit yourself to a certain kind of American literary fiction, it's easy to forget about the different kinds of books that are being written. You can forget to be ambitious, both as a reader and a writer.

The point about sales is relevant because it suggests there are cultures out there that are supporting and consuming, on a vast scale, challenging works of literature. Works of literature that in the United States would sell only a few thousand copies, if they managed to find a publisher at all. The success of these texts in Spain or Italy or wherever contributes to a kind of national conversation that we're perhaps not having here in the U.S.
