Even among non-neuroscientists, determining the origin and purpose of consciousness is widely known as “the hard problem.” Since its coinage by philosopher David Chalmers thirty years ago, that label has worked its way into a variety of contexts; about a decade ago, Tom Stoppard even used it for the title of a play. Unsurprisingly, it’s also referenced in the episode of Big Think’s Dispatches from the Well above, which presents discussions of the nature of consciousness with neuroscientist Christof Koch, Vedanta Society of New York minister Swami Sarvapriyananda, technology entrepreneur Reid Hoffman, Santa Fe Institute Davis Professor of Complexity Melanie Mitchell, and mathematical physicist Roger Penrose.
