Daniel Dennett, a philosophy professor at Tufts, plays the friendly grandfather role well. I think it comes off much better than Dawkins’ British accent snipery.
In this video (from TED Talks), Dennett starts off by talking about how humans took an animal (the Aurochs?) and domesticated it over time to improve it, eventually leading to the modern cow. And from there he goes on to religion. His taltk came right after the one by Rick Warren (author of The Purpose-Driven Life), so some of the remarks flow from that. It’s worth watching, and more or less echoes his Breaking the Spell: Religion as a Natural Phenomenon.
