Here's a great video I just found on YouTube a couple of days ago. Daniel Dennett at TED Talks 2 years ago explaining the design of religion and giving a verbal smack down to Rick Warren who just happened to be in the audience. I'm a big fan of TED Talks and an even bigger fan of Dennett. He's easily my favorite of the "Four Horsemen of Atheism". Go read "Breaking the Spell" right now, fool!
