The talk on consciousness and the brain is by philosopher John Searle. He is Slusser Professor of Philosophy at University of California, Berkeley, and the winner of the 2000 Jean Nicod Prize and the 2004 National Humanities Medal. His books include The Mystery of Consciousness and Mind, Language And Society: Philosophy In The Real World among others.
It’s a great video – he crams a lot in and it’s worth watching several times.
*Videos of the talks are up now at the TEDxCERN web site.
