~3000–1200 BCE – The Age of Bicameral MindAs per Julian Jaynes, humans experience thought as external commands from gods, rulers, and ancestors, rather than as internal introspection.Language and oral traditions serve as the primary form of cognitive structuring, guiding behavior in a world without self-reflective thought.Civilizations like Sumer, Akkad, Egypt, and early China function under a bicameral cognitive structure, where divine authority is absolute, and personal agency is minimal.The collapse of bicameralism began around 3000 BCE, accelerating after 1200 BCE, as societies became larger, more complex, and less reliant on rigid theocratic rule.
