On September 7th, 2010, Christopher Hitchens and David Berlinski squared off at the Fixed Point Foundation in Birmingham, Alabama before a capacity crowd of 1,200. The question being debated was whether or not a purely atheistic society is preferable to a religious one. Overshadowing the debate was Hitchens' recent cancer diagnosis (as you can see from the above picture, Hitchens has lost his hair due to chemotherapy). The debate was filmed and will be released on DVD in November, just in time to make it on to your philosophically-inclined Christmas wishlist.
I'm especially interested in listening to this debate because, while many debate opponents are mismatched, I think Berlinski and Hitchens are well suited to debate each other. Both men are rhetorical, witty, iconoclastic public figures. This decreases the chance that the debate will be won or lost based on one debater out-talking another.
