There was a period of a few months, however, when I had a dreadful physical pain. I had just started writing a particular section of the novel and was initially worried that it would affect my work. I was woken by awful nightmares; I saw several doctors, tests were performed, nothing came of them, and the medics were mystified.It was two days after I finished writing the section that the penny dropped. The pain had suddenly disappeared and so too had the nightmares. I'd got things muddled. The pain and the nightmares were both psychosomatic.

A poison can hardly be called safe if for some reason specific to me it's ineffective against, say, my body. But the power of story on the human mind is such that anecdote is often more persuasive than numbers. That's why news stories often concretize the impact of a change in government policy by following the story of one person.

I'm not sure, however, that what I have amounts to faith in the sense commonly understood. I have difficulty understanding the function of the word "believe" in the realm of faith, a basic term in the grammar of every creed.

Novels need readers of a certain kind, people who are patient and enjoy immersing themselves in another perspective for uninterrupted stretches of time. Reading habits might well be changing. People who pay for novels might overlap significantly with those who engage in Twitter and Facebook.

The difference does not lie in the things that news does that novels do not do, but in the things that novels do that news cannot do. In other words, this basic technique of news - just one among many - is something a novel can use, but a novel can deploy a multitude of other techniques also. Novels are not bound by the rules of reportage. Far from it. They're predicated on delivering experience.

There is snobbery in the idea that the modern cult of celebrity has not touched the lofty realm of letters. We are like visitors to a garden or flower show who wander the pathways and do not notice the beautiful flora but instead exchange murmurs about the appearance of the soil.

I had an indefatigable curiosity about everything. But why should my fate have depended upon that? Why does the curiosity of a child born into the lowest classes have to overcome everything put in his or her way to mute that curiosity, when a child born to parents with access to the advantages of life will have his meager curiosity kindled and nurtured? The unfairness is horrifying when it is properly understood as an unfairness meted out on children, on infants, on babies.
