Everything seems fine until you're about 40. Then something is definitely beginning to go wrong. And you look in the mirror with your old habit of thinking, 'While I accept that everyone grows old and dies, it's a funny thing, but I'm an exception to that rule.

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.

I want incremental improvements. There's the record of all the revolutionary and violent change and extremism in general - it's dreadful.

One thing you can't help noticing in South America and in Latin culture, generally, is how nice people are. Although when I went back to Spain - my mother lived in Spain and both my brothers lived there - after the Uruguay trip, I thought, "Oh great, Hispanic people." But they weren't nearly as nice as the Uruguayans. They're quite proud and pissed off, the Spaniards.

When things are going well, you do have the sense that what you’re writing is being fed to you in some way. Auden compared writing a poem to cleaning an old piece of slate until the letters appear. The only way you could reveal your god is perhaps under hypnosis. It’s sacred and it’s secret, even to the writer.

It is straightforward — and never mind, for now, about plagues and famines: if God existed, and if he cared for humankind, he would never have given us religion.

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.
