What most caught my eye about this widely linked piece was its reference to Kohlberg ‘s work about the development of a moral sense. The author cites criticisms that Kohlberg’s structure is gender- and culture-biased, with some evidence to support those criticisms. I found the article to be very interesting, and especially enjoyed this bit:

Similarly, children growing up in deeply religious Mennonite communities distinguish between rules that apply because they are written in the Bible (e.g., that Sunday is the day of Sabbath, or that a man must uncover his head to pray) and rules that would still apply even if they weren’t actually written in the Bible (including rules against personal and material harm).

What I like best is that it clearly indicates that morality is unrelated to religious edict, and even children can detect the difference.
