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.

Until I reached my late teens, there was not enough money for luxuries - a holiday, a car, or a computer. I learned how to program a computer, in fact, by reading a book. I used to write down programs in a notebook and a few years later when we were able to buy a computer, I typed in my programs to see if they worked. They did. I was lucky.

I'm interested in how a person forms her beliefs, how that happens. Beliefs of all kinds make up the animating force in each of us. Without them we would be paralyzed, lifeless - the glove without the hand.

The technology broadens an individual's social field massively and at the same time makes it much, much easier and cheaper to consume gossip. We have the same appetite for gossip, but now its acquisition is even easier than grabbing sugary and fatty foods off a supermarket shelf. And look where that got us. When you watch people in public desperately punching away at their machines, it's hard not to think of addictions.

Another effect of news articles is that the events, however frightening, can thus be consigned to the box of things that happen to other people, not us, and that we are doing things to bring them under control. This is the diet we're fed all the time, so we acculturate to it. And news must, in turn, follow the form to which we - our bodies - are accustomed: describe the event, incite the fear, then say how it's being addressed, how the herd's alpha males are dealing with it.

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.
