Harvard cognitive psychologist, linguist and popular science author Steven Pinker (The Language Instinct, The Blank Slate, The Better Angels of Our Nature) gave his very first public talk about his new book, Enlightenment Now, at FFRF's 40th annual convention in Madison, Wisconsin. His optimistic talk is replayed in full on this week's show while Dan and Annie Laurie are traveling to the Central Florida Freethought Community's cruise to the Bahamas.
