'Michael Shermer is our most fearless explorer of alternative, crackpot, and dangerous ideas, and at the same time one of our most powerful voices for science, sanity, and humane values. In this engrossing collection, Shermer shows why these missions are consistent: it's the searchlight of reason that best exposes errors and evil.' Steven Pinker, Johnstone Professor of Psychology, Harvard University, and author of Enlightenment Now: The Case for Reason, Science, Humanism, and Progress
