Bicameral Mind
The Bicameral Mind refers to a concept that was suggested by Julian Jaynes in his book The Origin of Consciousness in the Breakdown of the Bicameral Mind.
I am personally convinced by the evidence presented and basically accept it as true.
Anyway, what is the Bicameral Mind? The Bicameral Mind concept is basically that before humans were conscious, they basically worked in a āsplitā manner. The right brain would provide orders to the right brain (via auditory and visual hallucinations, though mainly auditory ones), which the left brain would then follow absolutely. The way this works in practice is that when a person feels stress, a voice appears which tells them what to do. Then they know what to do the next time it happens.
Yeah, that sounds like schizophrenia. Though my understanding (after reading about it for a while) is more like schizophrenia accidentally unlocks something that was always there.
Jaynes goes further and claimed (and I largely believe him) that the Bronze Age civilizations were not conscious and a majority of their population was āBicameralā. I plan to go into more detail later, but it does go a bit further.
That said, I know exactly why the book failed to make the theory (series of hypotheses) accepted. I will eventually move that to the bookās dedicated page, but Iāll explain it here anyway.
Jaynes writes a bit poetically. This sometimes makes it difficult to understand what heās getting at and makes him sound very certain about what heās talking about. Thatās the first issue.
The second issue is that Jaynes kindaā¦jumps forward in an unnatural way. To be clear, the logic often does follow, the problem is more the lack of steps between. Itās sometimes too abrupt. If you are not already on-board, those jumps can end up losing you.
Some things also could be described more clearly, but they often arenāt.
The best part of the book is where he goes over the various definitions of consciousness, explains the issues (and cites research on those things) and then provides his own. That is pretty damn good.
The rest is pretty okay, though I havenāt finished reading it.
If you actually want to learn about the Bicameral Mind, Iād actually just recommend reading the stuff on the Julian Jaynes Society website.
The last thing Iāll note is that coordination is maintained through peoplesā delusions mutually reinforcing each-other. Basically, if person A says āI heard x voice in my headā and person B goes āI also heard x voice in my headā they will end up concluding that the voice in their head is the same, which results in gods being shared between people. Thatās also why the earliest states were extremely religious, but also not religious in the modern sense at all.
CGP Grey Split Brain
This section is going to be filled in eventually, because in it Iām going to point out that CGP Grey is a little dumb in the conclusions he has regarding split-brain research and this has probably resulted in some kind of damage, though I canāt say what for sure.
