My husband recently found a WNYC Radio Lab podcast on the topic of morality and when people form it. He downloaded it for me, because of course its something I would be interested in. It's a really fascinating topic, and the hosts do a great job at exploring great questions about this topic.
I found this topic very interesting because I have a toddler who is clearly forming many ideas about life and the way things work. She is learning right from wrong and asking a lot of "why" questions when we tell her something is good or bad.
OK download it and listen sometime when you have laundry to fold.
