In episode 162 of The Michael Shermer Show, Michael speaks with one of the nation’s preeminent experts on economic policy, Benjamin Friedman, about his new book Religion and the Rise of Capitalism — a major reassessment of the foundations of modern economic thinking that explores the profound influence of an until-now unrecognized force — religion.
