If you love to hear new important voices, or you’ve ever endured the creative struggle, listen to this podcast. It will touch bone.

Humankind created war, and is therefore capable of ending it. This is the daring theme of science scholar John Horgan’s new book, “The End of War.” In Part 1 of my podcast interview with Horgan, he discussed evidence that human warfare has existed for only the last ten thousand years: a blip on the historical screen of human history.

Most of us perceive warfare as the single-most horrific tool employed by nations in the settling of disputes. But how often do we hear convincing counter-narratives that offer hope for a better way? Listen to my interview with scholar John Horgan, author of “The End of War” to hear a unique perspective on cultural evolution, and his conclusion that a warless future could be humanity’s next step.

The year’s end brings reflection on the power of great creative work. This December, I Interviewed Egyptian-American filmmaker Jehan Harney about her film “Dream of America,” which documents Iraqi men who fled to America after risking their lives in defiance of Saddam Hussein. Listen to how the men’s story literally made Washington Post headlines earlier in 2010. The resulting publicity garnered welcome support for the film’s main subject, a father of four, whose fidelity to the U.S. led him into serious and continuing personal struggles.
