Our biggest art forms are film and television, and there hasn't been a great film about 9/11 yet, nor has there been a great television series. Something like The Wire gives us a rich and fully achieved picture of the wasteful, cruel War on Drugs; something like The White Ribbon gives a perspective on World War I that could only have been presented long after the event itself.

It's an Obama book, certainly. I was delighted, and astonished, to hear recently that he was reading it. It's a book about a new kind of American reality, one that takes diversity for granted. It doesn't celebrate diversity, actually, it just says: this is how we live now.

The banality of evil transmutes into the banality of sentimentality. The world is nothing but a problem to be solved by enthusiasm.

Still, there's that faint glimmer of hope we feel when we sense, in other people, the same kind of attentiveness to life that we take comfort in. Why else would anyone watch Haneke films or read Sebald? The material is grim, but it's redeemed by the quality of the attention.

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.

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.

The novelist loses, every time. Politics is insidious, the modern conduct of war (from shoulder-launched rockets to drone strikes) is insidious. Someone presses a button in California and twenty people are incinerated at a wedding in Pakistan. The killer is spared the sight of the corpses.
