But I'm not a small-literary-novel kind of guy, and once I'd developed the world in the first couple of hundred pages, I felt that there was potential here to go on and write an engaging story set in that world. So that's what I did. This probably ruins things both for the people who want small literary novels and for those who want action-packed epics, but anyway, it's what I wrote.

Even the best of us have certain psychological mechanisms that can suddenly kick in and turn us into monsters. That to me is the basic message of events like the rise of Nazism, the Salem witch trials, and so on: not that bad people do bad things, but that good people do bad things. It's distressingly easy for those mechanisms to be triggered, either consciously by demagogues, or naively by people who think they're trying to do the right thing. Which is why I think it's more akin to tic-tac-toe.

I'm strictly a one-project-at-a-time kind of guy. If I came up with a compelling idea for a different book while working on a project, I'd probably abandon the first project and go with the new idea.

That we occasionally violate our own stated moral code does not imply that we are insincere in espousing that code.

Men who believe that they are accomplishing something by speaking speak in a different way from men who believe that speaking is a waste of time.

Even the best of us have certain psychological mechanisms that can suddenly kick in and turn us into monsters.

A few dud universes can really clutter up your basement.
