6 (seemingly) very interesting talks (videotaped, freely available).
by Daniel Dennett, Steven Pinker, Marc Hauser, Antonio Damasio, Michael Gazzaniga, Lisa Randall.

On Evolution, Religion, Neurology & the Brain, Humanity, Morality etc...

--
Edit:
-The Dennett talk is about the same as he did at TedTalks, but somewhat longer (42m in stead of 25m).
