A (not very widely accepted) theory on how human consciousness developed. I think it goes something like: Once we had a split mind where one side had a god-like voice that gave orders/ideas/directions in the form of auditory hallucinations to the other side of our mind, which acted on them. We were intelligent but had no real consciousness or ability to reflect until the bicameral mind broke down a few thousand years ago, which is when ancient texts began to show self-consciousness and self-reflective concepts, and when religions transitioned from pantheons of smaller (maybe personal) deities to larger and more abstract ones. Schizophrenia in modern humans would be a vestige of all this.Â
It seems insane to me, but it’s fun to read about older scientific theories that either fell out of favor, were debunked, or were just destined to be on the fringe. Â
