Afghanistan, Iraq and Libya are all reasons to think war has increased. While many think war is on the rise, Steven Pinker argues just the opposite. Pinker takes the long view, arguing that over thousands of years human violence has decreased. Today is the most peaceful time in humanity, he says. Pinker dips into various disciplines to not only argue that we are living in a golden age of peace, but to explain why this is so.
Steven Pinker, author of several popular books. His most recent is "The Better Angels of Our Nature: Why Violence Has Declined"
