I read your reply on bozz's post and this post as well. Great thoughts. While I disagree with your final conclusion ("humans are selfish" — as a 25 year Zen practitioner and Jungian psychological student, I don't think it's that simple. Both Jung and the Buddha would reject such a statement, and me too) I do like how you put everything.

And using Simpsons to do it — chef's kiss!
