In a special session at the meetings of the American Academy of Religion on November 20, 2011, Robert Bellah discussed his new book, Religion in Human Evolution, with members of a distinguished panel.… Why was this event so special? It was not just the distinction of the members of the panel themselves, beginning with Bellah, arguably the country’s best known sociologist of religion and author of such seminal essays as “Civil Religion in America” and “Religious Evolution,” and groundbreaking books, including Habits of the Heart and Tokugawa Religion. Rather, the significance of the event lay in its recognition of the importance of the book’s project, a breathtaking survey of the whole sweep of the history of religiosity, which is nothing less than the history of humankind.
