Specialization reflects left brain thinking. The way the circuitry of the left brain processes data is connected to the differentiation of reality into its many details. It will make us notice the tiny speck in the eye of another. Like in calculus, differentiation finds the slope of a curve at a given point A; unique angle.
The right brain is the opposite in that it is more integral. The circuitry of the right brain process data by trying to integrate it. In calculus, integration finds the area under the same curve from A to B. This is more like a generalists who brings a wide range of specialties, from A to B, under one umbrella; jack of all trades. We; humans, have the capacity to do both, but we are much more left brain orientated, as inferred by the dominance of specialization.
In the symbolism of the tree of knowledge of good and evil and the tree of life, these two trees appear to be connected to the contrast between the left and right brain data processing; neurons are like little trees. Knowledge of good and evil is about differential thinking and the beginning of specialty behavior; finds the slopes at each point in behavior. Scratching your nose when itchy is good but picking your nose in public is not; unique slopes.
The tree of life is more about natural instinct which allows animals to integrate within their species and within integrated eco-systems. The symbolism of losing the tree of life; taking away, and gaining the tree of knowledge appear to be about the migration of human consciousness, away from the right brain into the left brain; shift from integrated instinct to differential thinking needed for civilization. It appears to have happened, not that long ago, creating an entirely new world view; details of the universe appear or become more noticeable due to the different circuitry.
The potential problem with differential thinking, and its urge to specialization, is that the specialist can lose track of the forest because of the trees. The specialist can see the trees in front of them in great detail. But he or she can become too near sighted, to see how this tree relates to the whole forest; too egocentric.
The generalists, would be more right brained and would be more like an integral thinker. They are like someone who is up on a mountain and can see the entire forest. However, this view is too far away from each tree to see all the details. However, because the generalists can see the whole forest, he/she can see how apparently unrelated things, relative to specialties, are connected. How does quantum physics affect life? Or, what do the trees of knowledge and life have to do with the brain? This is not for specialists to figure out, since neither knows enough about the other. That needs a larger perspective from A to B.
In construction, you have specialty of trades, from laborers, masons, carpenters, plumbers, electricians, painters, landscapers, interior designers, etc. None can build the house by themselves, but as a team they all contribute via their specialty. But they need a construction foreman, who can sequence and integrate the specialty trades, from A to B, to maximize time and resources.
If you let any specific trade be the foreman; electrician for example, they would think from the POV of their own area of specialty and try to showcase that, at the expense of the integral project, which is the completed building on time and budget. Big Government is never on budget since there are to many company politics egos; differential, and not enough integral thinkers.
Science continues to generate data faster than it can create theory. This is because there is not enough right brain contribution in science ; construction foremen. There are plenty of craftsmen, in all specialty niches of science, but not enough integral thinkers to bring all the data together, from all over science. This would require learning to migrate between the two hemispheres of the brain; go left to let the left circuitry show the important details, and then go right to let the right brain circuitry process this into 3-D theory. That will be the future of humanity and science, allowing all the specialties to sequence better, like in the ancient times. Integral theory, even with less specialty knowledge than today, was able to build the pyramids with hand tools. Some could see the forest; goal, in spite of all the technical difficulties we will see; trees.
Religion is important to this future end, since religion still uses more right brain. For example, God creating the universe is an integral theory; integrates reality from alpha to omega. However since it is right brain, it does no offer enough detail for all the left brainers of science, who are specialist, that focus on the tiniest of details, that the integral God theory, cannot explain. However, it nevertheless is a way to help place our consciousness in the right brain, so one can learn to make use of the integral circuitry of the right brain, to form integral theory. I used this to form a water theory for life and consciousness.Water is a forest variable that integrates all the organic variables; trees, from alpha to omega.
