The site was a palimpsest, as was all the city, written, erased, rewritten.

Each neighborhood of the city appeared to be made of a different substance, each seemed to have a different air pressure, a different psychic weight: the bright lights and shuttered shops, the housing projects and luxury hotels, the fire escapes and city parks.

Not in this specific form. But all great cities are inhabited by ghosts. A book of this kind could probably be written about Jakarta, Manila, or London by anyone who had a feeling for the invisible truths of those places.

I became aware of just how fleeting the sense of happiness was, and how flimsy its basis: a warm restaurant after having come in from the rain, the smell of food and wine, interesting conversation, daylight falling weakly on the polished cherrywood of the tables. It took so little to move the mood from one level to another, as one might push pieces on a chessboard. Even to be aware of this, in the midst of a happy moment, was to push one of those pieces, and to become slightly less happy.

I'm grateful for the likes of Kundera, Murnane, Markson, Berger, and, in his recent work, Coetzee. But no matter how celebrated they are, critics still consider them askance. Elizabeth Costello, for example, is a great novel, but it got quite a critical panning when it was published. The complaint was that it was simply a book of speeches, without the machinery of conventional fiction. Markson's books are compilations of facts and alleged facts, very artfully.

It is dangerous to live in a secure world.

Being Nigerian is a strong part of my identity. Being American is a strong part of my identity. And there are important parts of who I am that really have nothing to do with my national connection.
