The twentieth century saw a professionalization of fiction writing, particularly in its second half and particularly in the Anglo-Saxon world - not so much mainland Europe, for example. This professionalization is a tragedy. Hand in hand with this - and I have no idea what the causal relations are - there has been a rise in the idea of The Author, so that today one often has the impression that what's selling the book is not the book but the author.

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.

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.

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.

By delivering experience, novels can alter the stance we adopt toward news - not much, I'm sure, but they can make it a little more difficult for us to consign "other people" to our tidy boxes. Widening our imaginative life might - it's not hard to imagine - also develop our ability to contemplate counterfactuals and our capacity to speculate about how things might differ from how they're being represented.

The mathematics is the odd one, odd because I'm not sure how to measure its effect. It is so fundamental to my outlook on everything and yet I'm not even sure how. It must be because in my formative years it was everything to me, the single place of beauty in my life, and of breathtaking beauty at that. I still believe that pure mathematics is the most creative thing that humanity does, though I am no longer a part of it.

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.
