Christopher Ferguson on how mental illness is shaping culture, politics, and history

Christopher Ferguson is a professor of psychology at Stetson University and the author of "How Madness Shaped History: An Eccentric Array of Maniacal Rulers, Raving Narcissists, and Psychotic Visionaries." I spoke with him about mental illness, personality disorders, and "madness," and how these have all shaped history, as well as about how our modern understanding of things like anxiety, depression, and narcissism, is impacting discourse, politics, and individual lives.

Please forgive my wet hair, gracias.
