I would say I'm an ironist not a satirist. All you do is you take existing tendencies and crank them up, just turn up the volume dial. Which is a technique of science fiction, apart from anything else.

Oh Christ, the exhaustion of not knowing anything. It's so tiring and hard on the nerves. It really takes it out of you, not knowing anything. You're given comedy and miss all the jokes. Every hour you get weaker. Sometimes, as I sit alone in my flat in London and stare at the window, I think how dismal it is, how heavy, to watch the rain and not know why it falls.

All that rejection from Republicans has a bit of a racist element. It was very necessary to have a black president, and it's been a great thing. It will help, in the end, to ease the trauma of slavery and civil war. The war against slavery cost almost 800,000 American lives - that's how strongly they felt about it. And it's not going to go away in a century.

The process of writing a novel begins with a pang, a moment of recognition, and a situation, a character, or something you read in a paper, that seems to go off, like a solar flare inside your head.

I think Jorge Borges said that when Argentineans die they turn into angels and go and live in Uruguay. But for the rest of South America, you have to say that it's getting there - becoming civilized - and will get there. It's had a real grit war in history. The choice between those societies until recently was the choice between tyranny and chaos. Everyone understood that. You've got to have a strong man, or it's going to be a mess.

So I am lonely, but not alone, like everybody else.
