Hochschild, a journalist who teaches at U.C. Berkeley, focuses on the history of a movement. But not just any movement. As he points out, this was the first movement for social justice in the history of the world. A small group of mostly Quakers in London did something that was hitherto unheard of: they devoted their lives to a movement from which they would draw no personal benefit. In so doing, they set the template for every social movement since. Hochschild writes with wit, authority and a deep sense of empathy.
