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.

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.

We experience life as a continuity, and only after it falls away, after it becomes the past, do we see its discontinuities. The past, if there is such a thing, is mostly empty space, great expanses of nothing, in which significant persons and events float.

Note-taking is important to me: a week's worth of reading notes (or "thoughts I had in the shower" notes) is cumulatively more interesting than anything I might be able to come up with on a single given day.

I couldn't remember what life was like before I started walking.

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 deeply respect American sentimentality, the way one respects a wounded hippo. You must keep an eye on it, for you know it is deadly.
