I'm not hopeful about America, and I'm not hopeful about the world, no. Life goes on and, for those of us who are lucky, there's a great deal to enjoy in it. But will things get better for most people? I don't know. I don't see the evidence.

In a sense, Open City is a kind of Wunderkammer, one of those little rooms assembled with bric-a-brac by Renaissance scholars. I don't mean it as a term of praise: these cabinets of curiousities contained specific sorts of objects - maps, skulls (as memento mori), works of art, stuffed animals, natural history samples, and books - and Open City actually contains many of the same sort of objects. So, I don't think it's as simple as literary inclusiveness.

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.

I just realized that we're facing here is an empathy gap. And this was just another way to generate conversation about something that nobody wanted to look at.

But a book suggests conversation: one person is speaking to another, and audible sound is, or should be, natural to that exchange. So I read aloud with myself as the audience, and gave voice to another's words.

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

The shape the words end up taking are themselves the meaning of the words, they are retrospectively what we meant to say. There's no way of knowing this until you register it in visible form. But the other side of this is that you do have some idea of where you are going.
