Added 5.22.18. In this 2012 episode, Milt talks with two experts about man’s similarities and differences with primates. Is our own free will to some extent an illusion, because we’re hard wired to act in certain ways in certain situations? Discussants probe the tension between our biological programming and our higher nature, which stems from a more acute consciousness, ethics and the physical ability to produce nuanced linguistic expression. Guests are Paul Reber, Northwestern University psychologist and head there of the Brain, Behavior and Cognition program; and Dario Maestripieri, author of “Games Primates Play: An Undercover Investigation Of The Evolution And Economics Of Human Relationships.”
