The human brain has two centers of consciousness. One center is connected to the conscious; ego and other to the unconscious mind; inner self. Humans differ from animals in that animals only have one center, analogous to the inner self of humans. The extra vitality and the enhanced sensory ability of animals is connected to animals being centered via the inner self. This center has much more access to the brain's capacities.
The conscious center; ego, found in humans, is relatively new in term of evolution. Based on civilization, this center appears to be less than 10,000 years old. The conscious center gives us choice and free will apart from the instincts within unconscious mind. The result is we, as humans, have lost our natural capabilities and access to natural human instincts, in exchange for cultural conditioned analogies.
Instead of being able to track food, we learn how to go to the store. This takes much less brain power than tracking and hunting, but it nevertheless leads to the same results and better, allowing any human to participate. The prosthetic affect makes things better for more people, by requiring less brain power. This can be regressive in terms of natural selection since everyone gets selected and weakness is perpetuated.
The previous stage of evolution, over the past 10,000 years, was developing the ego center. The next stage of human evolution is learning to return to the unconscious center, so one can increase the access to the brain. Often in religions, paradise is a return to outer simplicity; nature, along with enhanced inner complexity; able to integrate.
Once that stage is reached, the next step would be to use both centers to help raise the set point. of the brain.The future may be natural humans who can survive in or out of culture; fluid adaption.
