I find it pleasing that their theory is consistent with Julian Jaynes's theory about the origin of consciousness. One could view this even as an extension of Jaynes's theory. First, we became conscious, then self-conscious. Consciousness was a prerequisite to any form of society. Self-consciousness was a prerequisite to a moralistic society. The details of the form of deity seem to me a proxy for the underlying question about how the brain was evolving over this period. Although the article notes that this fact is in dispute, at least to me it seems striking that there do not appear to have been any large-scale wholly atheistic or agnostic civilizations in history until recently. To continue the thought about the biological substrate for consciousness and self-consciousness, I wonder what that implies about whether or how are brains have evolved in the recent past? Is there some allele or set of alleles that express for pro-social tendencies that are required for pluralistic, capitalistic, atheistic/agnostic civilizations?
