Conversation Piece: Steven Pinker on "Secular Enlightenment"

I'd love for this blog to become something of a forum.  This video featuring the scientist/author Steven Pinker begins fairly innocuously, but towards the end he touches on several large and contentious issues.  Feel free to use the comments section to throw in your reactions, opinions, etc.

(Sorry about the ad at the beginning of the stream...Salon has to bring in the dough somehow I guess.)
