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.

Our interaction with our friends, for instance, is in large part an interaction with representations in our own head of the people before us. That's why a friend can surprise or disappoint us.

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.

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.

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.

I am at my happiest when I'm problem solving and a large part of writing is for me a lovely labor in problem solving. Every act of discovery in writing involves a process of figuring out why I'm not seeing what I need to see. Niggling feelings, discomforts, a sense that you've forgotten or overlooked something, a sudden curiosity about what if here? - these are priceless. They are the bases of problems and lead the way.
