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.

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.

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.

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.

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.

The mathematical tilt remains basic to my epistemological perspective, my howling plea in the still of night for epistemic humility. Mathematics gave me that as, also, did the difficulty I had in talking to my parents. How proofs are conceived is unfathomable. Clearly, there are certain conditions in which the revelation takes place.

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.
