Neuroscientist, philosopher, podcaster and bestselling author Sam Harris, has been exploring some of the greatest questions concerning the human mind, society, and the events that shape our world. Harris's search for deeper understanding of how we think has led him to engage and exchange with some of our most brilliant and controversial contemporary minds—Daniel Kahneman, Robert Sapolsky, Anil Seth and Max Tegmark—in order to unpack and clarify ideas of consciousness, free will, extremism, and ethical living. For Harris, honest conversation, no matter how difficult or contentious, represents the only path to moral and intellectual progress. Featuring eleven conversations from the hit podcast, these electric exchanges fuse wisdom with rigorous interrogation to shine a light on what it means to make sense of our world today.
