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.

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 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.

I had a tough childhood, yes. I was born in rural Bangladesh to parents who had had no education beyond high school. We moved to the UK where I grew up in poverty, in some of the worst conditions in a developed economy, before moving to the projects - heaven - and I went to unremarkable schools before going to university. My father was a bus conductor first and then a waiter, and my mother a seamstress.

One problem I have with talking about myself in the context of class divisiveness is that I can be - and indeed have been - used by others to demonstrate its absence and that it's only a matter of hard work to move upward socially. After all, how could I complain about anything, if the retort is: "But look where you got to? It can't be all that bad." But this is nonsense as an argument quite aside from its empirical absurdity because no single case can invalidate a statistical claim.

My parents were entirely unpredictable and what they said very unreliable, which meant I became very attuned to the range of other signals human beings give out - body language or what Freud graphically called the "betrayal that oozes out of him at every pore," betrayal, that is, of what they really mean. I have that to this day, and it makes conversation exhausting because I'm listening not just to the words of the person in front of me but also to their body. It's as if there are two radio stations on at the same time.

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.
