University of Texas at Austin professor and moral philosopher Prof. J. Budziszewski discusses his new book, The Pandemic of Lunacy: How to Think Clearly When Everyone Around You Seems Crazy, which examines 30 modern delusions and why they spread. He argues today’s irrationality is motivated, often contains a grain of truth, and metastasizes as one false premise leads to others, with social media acting as a force multiplier. The conversation covers relativism, abortion premises leading to infanticide arguments, radical individualism sliding toward authoritarianism, and debates over sex differences and the claim that men can be women.
