In light of many of the discussions currently occurring on the site, I'd like to recommend a book that proposes a very different theory of how societies are organized. The book is Riane Eisler's The Chalice & The Blade.
I think the ideas and language in this book would expand and enrich the on going discussions on the various forums concerning how social norms are past from generation to generation, the role of religion in society and the division of labor, resources and power.
Copied from Wikipedia:
Eisler's international bestseller The Chalice and The Blade: Our History, Our Future, now in 22 languages, including most European languages and Chinese, Russian, Korean, Hebrew, Japanese, and Arabic, was hailed by anthropologist Ashley Montagu as "the most important book since Darwin's Origin of Species".
