In this edition of the Journal, Bill Moyers sits down with Robert Wright, author of the bestseller The Evolution of God, to discuss why Wright thinks that a concept of God is imperative to a moral society and that whether God truly exists may not be as important as how the idea of God has changed over time. Moyers also speaks with Mary Sweeters, of Greenpeace USA, and Erich Pica, of Friends of the Earth, about why they believe President Obama is not doing enough to save the environment and what they think needs to be included in climate change legislation. An essay on insurers’ efforts to steer healthcare reform legislation with big money—to the detriment of patients and medical practitioners—concludes the program. Broadcast date: July 17, 2009.
