169: Dualism

More at http://philosophytalk.org/shows/dualism. What is the relationship between the mind and the brain? Monists believe that there is only one substance or property in the Universe, be it physical (Materialists) or mental (Idealists).

John and Ken probe the mind-body with David Rosenthal from City University of New York, author of "Consciousness and Mind."
