Point of Inquiry is on a short hiatus right now as we transition to a new podcast team. In the meantime, enjoy these classic episodes from the POI archives, featuring Neil deGrasse Tyson, Bill Nye, Susan Jacoby, and other luminaries in the science and secularism movement.

Susan Jacoby is the author of Freethinkers: A History of American Secularism, now in its tenth hardcover printing and recently published in paperback. Freethinkers was hailed in the New York Times as an “ardent and insightful work” that “seeks to rescue a proud tradition from the indifference of posterity.” Named a notable nonfiction book of 2004 by The Washington Post and The Los Angeles Times, Freethinkers was cited in England as one of the outstanding international books of 2004 by the Times Literary Supplement and The Guardian. In this interview with DJ Grothe, Jacoby talks about the role that freethinkers played in American social justice movements, and discusses the forgotten history of Robert Green Ingersoll. Also in this episode, Tom Flynn asks Did You Know?, detailing facts about Robert Green Ingersoll and new data about nonbelievers from University of Akron, and Lauren Becker shares some thoughts on Darwin and Oliver Sacks and what these scientists teach us about ourselves.
