Two Harvard scholars with recent books are featured in this edition of Peace Talks Radio. Steven Pinker, author of The Better Angels of Our Nature: Why Violence Has Declined, says we seem to be living in one of the most peaceful eras in human history, despite the level of violence still at play in the world. He talks about his research. Then Donna Hicks talks about her book Dignity: The Essential Role It Plays in Conflict Resolution. She spells out 10 essentials for showing each other dignity and the 10 most common pitfalls. Two engaging interviews. Paul Ingles hosts.
