No kidding.

My sanity-saver ... but obviously not rationality-saver... has been to learn to encourage the people I'm dealing with to be more rational, at least when dealing with me. My inner circle of friends is made up almost entirely of people who ask themselves and each other that kind of question just as a matter of course, now, and dissect the answers to make sure they're correct and rational and well-integrated with the other things we know about each other.

That doesn't help at all when I'm trying to think about society in general, though.
