I don't know if there is a personal identity. We all imagine that we are absolute individuals. But when we begin to look for where this individuality resides, it's very difficult to find.

Why does the past seem so magical, so fraught, so luminous? At the time it was just, ugh, another boring bloody day. But, to look back on, it's a day full of miracles and light and extraordinary events. Why is this? What process do we apply to the past, to give it this vividness? I don't know.

Happiness was different in childhood. It was so much then a matter simply of accumulation, of taking things - new experiences, new emotions - and applying them like so many polished tiles to what would someday be the marvellously finished pavilion of the self.

Writing keeps me at my desk, constantly trying to write a perfect sentence. It is a great privilege to make one's living from writing sentences. The sentence is the greatest invention of civilization. To sit all day long assembling these extraordinary strings of words is a marvelous thing. I couldn't ask for anything better. It's as near to godliness as I can get.

I know some of my memories are made up and they are far more powerful than the things that actually happened. For example, I always remember my brother posting me a copy of 'Dubliners' from Africa, but he says he never did.
