The thing I really like about Twitter is the speed with which information reaches me. You find out things from Twitter long before they're on the news. That I think is valuable. In terms of actually tweeting myself, I have just lost enthusiasm for it. Maybe I'll do some of it this week to tell people about the PEN Festival and encourage them to show up.

I don't know what to say about literary critics. I think it's probably best to say nothing.

Many men start being friendly with women because they are trying to seduce them. I'm not trying to seduce them. I just like hanging out with them.

What I've always seen in writers and artists is the courage it takes to make an original work of art. I think the real risks in literature are linguistic and intellectual, and I hope we can highlight those, as well as political courage.

Everest silences you...when you come down, nothing seems worth saying, nothing at all. You find the nothingness wrapping you up, like a sound. Non-being. You can't keep it up, of course. the world rushes in soon enough. What shuts you up is, I think, the sight you've had of perfection: why speak if you can't manage perfect thoughts, perfect sentences? It feels like a betrayal of what you've been through. But it fades; you accept that certain compromises, closures, are required if you're to continue.

In Iran, fundamentalism was fuelled to an extent by the regime of the Shah being supported by the West.

The world is full of things that upset people. But most of us deal with it and move on and don't try and burn the planet down.
