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.

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.

Listening to people discussing a novel can be very interesting, if you've read whatever novel is being discussed. No one, it seems, ever says, "This is a great book but I didn't like it." Taking a little time to think about why this might be has been very liberating.

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.

I don't want you to think that I'm being willfully obtuse, but I've never really grasped how point of view could be regarded as a matter of choice independent of story. Point of view is intimately interwoven into the story that you want to tell - it is an aspect of it.

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.

Of course, an English aristocrat might have some contact with the staff downstairs and could adequately say a thing or two about inter-class dramas unfolding in the household. But something less parochial might be harder to come by. This is relevant because stories about the divisiveness of class are by definition stories that straddle class boundaries. A story about a miner in a mining town is not obviously one that speaks to the divisiveness of class. In other words, class doesn't just divide us in the world but it also divides us in the stories we're presented.
