Short clips from Beyond Belief - 2006 are now up on Youtube. Worth watching for the Sam Harris - Scott Atrand debate alone ( 1, 2, 3, 4.)
Atrand supplies what I think is probably the most interesting, persuasive, and downright intimidating critique yet of Harris's and Dawkin's work. His comments, angrily indignant as they might sound, are well worth considering (as Dawkins seems to be doing, heavily, from the audience in clip 4.)
Also check out Ann Druyan's inspired response to the claim that it's science, not religion, that fears the unknown.
If you're an insomniac like me, all twenty hours of the conference can be viewed here.
