The drive to pursue wisdom is engrained in every human being, right? Many have believed so. But in his new book, Ignorance and Bliss, Mark Lilla argues that a certain "will to ignorance" is also part of the human experience. Like Plato's Thrasymachus, many often want to throw up their hands in resignation rather than commit themselves to the pursuit of truth, creating a tension in human life that is sometimes reasonable and sometimes pathological. Lilla offers an explanation for this phenomenon, drawing on philosophy, religion, psychology, and history. He joins James Patterson to discuss the book.
