n.— «I think you’ll find that the stance of simply not caring much about God or religion (“apatheism” in the jokey parlance) is much less common than you imagine. It seems to be growing as people get wealthier, but a depressingly predominate chunk of humanity believes that God is indeed worth caring about, one way or another.» —“Cut God Some Slack” by dgriffith Freakonomics Blog Aug. 2, 2007.
