The Triune Brain Revisited

Postby Ierrellus » Sat Sep 15, 2018 6:37 pm

According to Paul MacLean the human brain has evolved in three stages. The first is the reptilian complex or the brain base. Over that emerged the paleo mammalian complex or the limbic system. Above that has developed the neomammalian complex or cerebral neocortex. All three brains remain as a trinity in one brain. All three continue to express themselves in our thoughts and actions. Consequently ideas such as seeing God as a trinity are natural if we see what we are. This is the reason the Genesis story of Adam, Eve and Serpent remains with us in the 21st century. The story is told through our own Eden consciousness with the three voices of our triune brain--the neomammalian, the mammalian and the reptilian.

From our experience as matter come the matters in our minds.

Three!--being, belonging, becoming--body, mind spirit--the number that best characterizes the categories of what it is like to be human.

I make it a point to revisit my brain from time to time. McLean thought that reptiles were totally drive ridden. Seems to me that he may have given them a bum rap. The more we find out about our animal kindred the more intelligent they seem to be but our anthropocentrism prevented us from seeing it.

So which part of the brain is Jesus, God, and the Holy Ghost?

I agree. Reptiles can act in ways that appear not to be purely instinctual. The Eden Serpent was quite articulate. So are the body's hungers and drives. The Adamic neocortex, however, supposedly offers more options between drive and fulfillment, between the urge and the action. Freud thought that the most evolved animals have a space for consideration of options between an urge and its consequent action. Sometimes that is more of a curse than a blessing. :D

Thanks for your question.
The idea of three in one is what's important.
My thesis: that myths and legends, religious or secular, have meaning for us as metaphoric renditions of actual human experiences of genetic and memetic evolutionary growth and development. The trinite brain theory fits the Eden story metaphorically. Maybe God in action can be seen as the brain's concern with homeostasis of interactive body functions. I like to think of DNA as a metaphor for God the creator.
We have historically had evolving ideas of what God is like. I'd have to say that the experience of God is the awareness of being at one with all that is.

How universal is the trinity in myths globally? It's an important part of some flavors of Christianity, but e.g. Judaism, polytheistic religions, Traditional Asian belief systems like Taoism or Confucianism, etc. to my knowledge don't have the same kind of structure. If it's derived from the human universal of our complex brains, we should expect to find it in all human cultures. And human-like brains (at least to the extent they are triune in the way you describe) are present in non-human primates. It's tough to test for chimps' reverence for the number three, but at least it suggests that any influence that had on our mythology should be present long before the advent of Christianity (or rather, the Catholic dogma of the trinity, which developed much later as far as I'm aware).

I also think the number three is special in ways that can be appreciated by any intelligent being, regardless of the number of layers in their information processing system. In fact, I would hypothesize that the causal arrow runs the other direction: the number of brain layers we have is due to the specialness of the number three. A three-body system has a particular set of complex dynamics, and it's possible that it's the simplest system that permits a certain kind of high-level infromation processing. Indeed, see a similar dynamic arises in computer design:

I admit it's hard to trace causality here; other diagrams omit hardware and show kernel, libraries, and applications as the three layers, so it could well be that we make three-layered computer architecture diagrams because we like the number three, rather than because there's an inherent three-ness to information processing.
