BloggingHeads.tv has a fascinating one on one video chat between science journalist John Horgan and consciousness researcher David Chalmers on the question of consciousness. No superficial chatting here, so don’t wade in unless you’re ready to get philosophical and think deeply about perhaps the deepest question of them all. Topics range from Descartes and The Matrix, to peyote trips and the question of whether a thermostat can be considered conscious (h/t AMNAP).
