Bicameralism

https://en.wikipedia.org/wiki/Bicameralism_(psychology)

Some “Westworld” theories are going to loopy places. But I think that the runners are referring to Julian Jaynes (largely discredited) scientific theory that consciousness started when mankind stopped hearing God’s voice in their head and realized it was their own inner monologue. Ergo after this moment “prophecy” became a recollected memory that didn’t happen anymore.

It’s a fascinating, and probably specious, psycholinguistic theory that retains a certain attractiveness, predictive power aside.

“The origin of consciousness in the breakdown of the bicameral mind” is the book’s title.
