There's a theory about morality that goes back to Margaret Mead's time, that says that for some people, the moral compass is internal, and for some people, it comes from an external source. At the time, the division was roughly described as the shame culture v. the guilt culture, but really, both can feel guilt--but for different things. The internally directed person feels guilt for what they do that is immoral, the externally driven guilt is for letting down the source of the moral direction, for breaking the rule.

Interesting! That said, I would immediately doubt the dichotomy -- can't one person have an internal moral compass regarding certain sets of rules and an external one regarding others?

Also, v., I'm loving this review.
