Instead, he launched into a full-on appeal for atheists to make public their beliefs and to aggressively fight the incursion of religion into politics and education (quoting Douglas Adams in the bargain). Scientists and intellectuals hold very different beliefs about God from the American public, he says, yet they are cowed by the overall political environment. Dawkins' scornful tone drew strongly mixed reactions from the audience; some stood and applauded his courage. Others wondered whether his strident approach could do more harm than good. Dawkins went on to publish The God Delusion and become perhaps the world's best-known atheist.http://www.ted.com Dan Dennett is a Tufts philosophy professor and cognitive scientist, renowned for his books, Consciousness Explained (1991) and Darwin's Dangerous Idea (1995). His most recent book, Breaking the Spell: Religion as a natural phenomenon calls for a rational examination of religion as a cultural phenomenon that has co-evolved over milennia to meet human needs. In this talk, which followed the presentation by Pastor Rick Warren, he takes issue with some of Warren's claims in The Purpose-Driven Life. (Recorded February 2006 in Monterey, CA. Duration: 25:29)
