Ethan's latest entry at the time of this writing was about author Kathleen Norris, a writer on faith and religion who makes a sharp and important distinction between the two. The former is about believing - which, suitably enough, is a deep subject for rationalists - the other about behaving. It's a mandate supported explicitly by my own faith tradition and, speaking as a nerd and introvert, one that I wrestle with. I struggle to do and not just think about doing.
Norris also makes known her TED wish - part of the newly announced TEDPrizes - to create a "charter for compassion" that might be circulated worldwide to emphasize that the Abrahamic faiths hold "doing unto others" in common.
