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.

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.

My parents have always had a very limited command of English. Of course, when we first arrived in the UK, none of us spoke English, but it's much easier for a child to pick up languages. But the problem was not a lack of English; the problem was poor communication in any language. Remember, my parents came from rural Bangladesh with little education. It was alarming for them, I'm sure, to watch their boy very quickly exhaust whatever ability they had to teach the child something.

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.

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.

There are a variety of ways in which a wedge is driven between the reality of the world outside, the motion of atoms, and our conception of what is there. Some of it has to do with what we're told, some of it to do with sensibilities that might be described as cultural, some of it to do with habit, some to do with heuristics we, as Homo sapiens, invoke because we cannot do otherwise - to name just a few of the impediments.
