Oh, I usually don't know a whole lot about a subject when I begin; the process itself teaches me a lot as I go along. Usually I know enough about one narrow area of the subject to start myself going, and then everything - including a lot more research - follows from that.

I think there's no question that historians create; they would tell you that, I think. If I'm trying to imagine an imperial Roman position, it's much easier to imagine the poor schlub who's not even sure why he's doing what he's doing than it is to imagine Caesar. At least for me. And I'm intrigued, too, by the position of the poor schlub who *still* finds himself supporting the imperial project.

Class is the most taboo subject in America. The American media would rather talk about race or perversion or anything else considered taboo before class.

I have written screenplays. Most recently for Errol Morris, who was thinking about doing his first fiction movie, and with a young director who wanted to adopt Project X. Errol was a hoot. I loved talking with him. We were a good match, too, because we both kept joking that we'd found the only other person on earth more ambivalent than we were about the project.

Empathy is a human trait. But lots of humans exercise some traits more energetically than others. By "the usefulness of empathy" I mean the way in which a progressive might claim that empathy is a crucial aspect of any benign political system, and the way a conservative might argue that not only is it not necessary, but it might not even be all that helpful, in that regard.

Does research get in the way of the story? It certainly can. Anything can, given that as writers we're all geniuses at procrastination. But mostly research teaches me about the world. Which often shows me the way, in terms of the story.

I don't beat at the details, but I do always keep in mind that anything that isn't A) moving the story forward or B) enlarging my understanding of the central characters has to be sacrificed. I have huge folders of details - research - with a story like Netherlands. Only a very small part of it gets used. The old iceberg analogy again.
