The video below, 21 minutes long, is for me one of the most profound lectures on “religion” I have ever listen to, or read.  The central theme is “compassion” and the Golden Rule, “Do not do to others what you would not have done to you”.
Religious scholar Karen Armstrong’s “wish” for a “Charter For Compassion” from the TED Conference, , in Feb. 2008.
From her biography on Wikipedia, .
“I say that religion isn’t about believing things. It’s about what you do. It’s ethical alchemy. It’s about behaving in a way that changes you, that gives you intimations of holiness and sacredness.” She points out that religious fundamentalism is not just a response to but, paradoxically, a product of contemporary culture. “We need to create a new narrative, get out of the rat-run of hatred, chauvinism and defensiveness; and make the authentic voice of religion a power in the world that is conducive to peace.”
Do we need any other moral law, or rule of behavior, other than acting with compassion towards our neighbors, and following the Golden Rule?
