This little book was, I have to say, boring and confusing, full of names and places hard to follow with not enough maps. But i kept on reading it to the end. I like how the author was trying to understand how otherwise rational people can refuse to believe a theory that is based in verifiable fact, but I don't know if he really answered (or could have) that. of course, religion was part of it, but timidity, resistance to change, hedging our bets, refusal to admit we are wrong, etc. were all explored too. It was also sort of a fantasy of a golden age of academia, where intellectuals travelled where their passions took them to hear and see things for themselves and where they got together regularly to bandy about ideas. They didn't seem to lack for funds to do this and they didn't seem to spend most of their time grading freshman essays. great life!
