Yes, there's a relaying of internal states that only a novel can achieve. In my view, the novel is one of Europe's greatest gifts to the world. America and Africa collaborated to give the world jazz. We'll call it even.

You know that this vignette and that vignette belong side by side, you know that a certain turn of phrase you've been saving will probably work best within a given section of the narrative. As in a jazz performance, writing lives or dies by what's produced in that moment. But that moment is attended by long preparation.

A MOB is not, as is so often said, mindless. A MOB is single-minded.

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.

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.

So, for a book set in 2006, Open City evades certain markers, while it embraces certain others. Julius doesn't use a smartphone, and he doesn't discuss contemporary US politics in any fine detail.

What's interesting about Twitter is the unmediatedness of it, the directness of it. I'm on a train somewhere in New York and I send out a tweet. Somebody sitting at dinner in Bombay checks their phone and they see it.
