Oratory, LD, general debate - Steve Pinker on TED.

Once again a link from TED.com. This is a brief history of violence which Steve Pinker talks about. A good overview of Hobbesian thought and the Leviathan, as well as some interesting evidence for an LD debater to use as a starting point for things like Capital Punishment or other cases involving conflict between an individuals rights and a society. http://www.ted.com/index.php/talks/view/id/163
