Yes, Julian Jaynes also expands on this point in his book, "The Origin of Consciousness in the Breakdown of the Bicameral Mind" and the section on "Divination."

Yes, Julian Jaynes also expands on this point in his book, "The Origin of Consciousness in the Breakdown of the Bicameral Mind" and the section on "Divination." He posits that forms of divination, augury, sortilege, etc... were invented as attempts by newly "post-bicameral" man to once more hear the "voices of the gods" that would give them authorization or assurance that their course of action was correct; an attempt to recapture the bicameral era, when "free will" as a concept did not even exist, and all of one's actions were in fact orchestrated by the gods (where Jaynes presupposes that what were referred to as "gods" were actually psychological phenomena).
