Rationally Speaking #134 - Michael Shermer on: "Science drives moral progress"

Common wisdom holds that the world is getting more violent, but is that really true? Leading skeptic Michael Shermer, professor and author of many books on science, morality and skepticism, argues to the contrary. Shermer's thesis in his recent book, "The Moral Arc: How Science Leads Humanity Toward Truth, Justice, and Freedom," is that as science has advanced our understanding of the world, we have become more willing to expand our circle of empathy beyond our own provincial "tribes," and more able to design our societies to encourage human flourishing. Dr. Michael Shermer is the Founding Publisher of Skeptic magazine, a monthly columnist for Scientific American, a regular contributor to Time.com, and Presidential Fellow at Chapman University. His new book is The Moral Arc: How Science and Reason Lead Humanity Toward Truth, Justice, and Freedom.
