I'm often called obsessive, but I don't think I am any more than anyone else.

I would like to visit the factory that makes train horns, and ask them how they are able to arrive at that chord of eternal mournfulness. Is it deliberately sad? Are the horns saying, Be careful, stay away from this train or it will run you over and then people will grieve, and their grief will be as the inconsolable wail of this horn through the night? The out-of-tuneness of the triad is part of its beauty.

Sometimes I'll spend an hour writing a tiny email. I work on it until I've created the illusion that I've dashed it off in three minutes. If I make a typo, I let it stand. Sometimes in fact I correct the typo without thinking, and then I back up and retype the typo so that it'll look more casual. I don't know why.

I no longer want to live in an apartment furnished with forklifts and backhoes.

Gandhi was important for another reason as well: his country was suffering under the British Empire, and yet he was leading a very singular kind of resistance to it. At the time he was speaking about the violence in Europe, his followers were in jail as prisoners of the British government.

I wrote about World War II because I didn't understand it. I think that's the reason that historians are drawn to any subject - there's something about it that doesn't make sense. I wanted to work my way through what happened slowly, and look at everything in the order in which it took place.

One's head is finite. You pour more and more things into it - surnames, chronologies, affiliations - and it packs them away in its tunnels, and eventually you find that you have a book about something that you publish.
