I like moral judgment to emerge from the reader. We are being sold a very simplistic morality by our leaders at a time when nuance and understanding are at a premium.

I suffer from vertigo. It's paralyzing in extreme situations. The most scared I've been as an adult was trying to conquer that fear by going climbing in Wales.

As I got older I became a kind of sub cultural junkie, foraging around in music, street fashion and eventually art, politics and the freakier reaches of the Internet, hunting the next discovery, the next seam of underground gold.

Several times in my life I've gone through long periods without sex or any other kind of physical contact. The hunger it produces is deep and low; it's possible to lose track of it, to forget or fail to perceive how it's emptied everything out of you and made the world papery and thin. Touch starved, you brush against existence like a stick against dry leaves. You become insubstantial yourself, a hungry ghost.

I tried to take seriously the idea that if you tortured language you might arrive at some new truth. Later it became clear to me that I was retreading ground by fighting the literary battles of the 1950s and 1960s, and that I was actually a bit bored by some of the books I professed to love.

I stand on my public record as a defender of the human rights of Muslims, notably my work for Moazzam Begg and other British Muslims detained without trial in Guantanamo Bay.

But it's the particularity of a place, the physical experience of being in a place, that makes it onto the page. That's why I don't just do library research. I very rarely write about somewhere I haven't been.
