Campbell’s great book The Hero with a Thousand Faces, because he is a classic hero and I thought it might help him. I also gave him The Lessons of History, a 104-page distillation of the major forces through history by Will and Ariel Durant, and River Out of Eden by the insightful Richard Dawkins, which explains how evolution works. He gave me Georgi Plekhanov’s classic On the Role of the Individual in History. All these books showed how the same things happened over and over again throughout history.
