Humans have two centers of consciousness; inner self and ego. The inner self is older and also occurs within all animals. It is the natural conscience center of the animal brain. The inner self is also the center of the brain's natural operating system, with the inner self of each species containing the firmware, which defines the nature of that species. In the case of humans, the inner self defines our human nature.
The second center is the ego. This is only found in humans. This secondary center evolved quite recently maybe 6000-10,000 year ago; Adam. The ego is the center of the conscious mind. I think therefore I am is an awareness of these two centers; I is ego will and choice, while instinct is inner self.
The biggest difference between the two are their languages. Since the inner self is common to all species, its language is more universal. It is based on objective reality, in the sense of being connected to the five senses, all of which directly interface reality to the inner self. We see photons of energy reflected or emitted by objects, which enter the eyes and signal the brain. The same is true of smell, and taste which are based on reality chemical signals, etc. Touch is pressure on nerves and hearing is based on sound waves all of which are signals from reality to brain.
The ego is more cultural and uses manmade language which is not objective in terms of interfacing reality to brain. There are over 6500 different human languages on earth. This alone tells us human language; sounds and symbols are completely subjective and arbitrary. There is no direct natural cause and affect between the word or sound for the word "cat" and what we see as a cat. The cat does not form the shape of the word; cat, nor does it make that sound, so why use that sound or word shape? Below is cat is eight languages. Which of the sounds do cats make and which word shape looks like a cat?
- American English: kitty /ˈkɪti/
- Brazilian Portuguese: fundo comum.
- Chinese: 公共储金
- European Spanish: fondo común.
- French: cagnotte.
- German: gemeinsame Kasse.
- Italian: cassa comune.
- Japanese: 共同出資金
The main difference between the inner self and ego is the inner self is in contract with reality through a more direct interface; five senses. The ego make use of subjective and arbitrary sounds and symbols, which we all may agree upon, but which do not reflect reality except as a subjective marker. Religions are often about finding the inner self so once can connect to reality through its direct interface; inner child or inner voice of the inner self.
The way the brain works is based on free energy potential. This schema was designed to work with the inner self, which is older and came first and is common to all animals. Their memory is based on signal hierarchy based on tangible reality signaling, such as photons for sight. Since ego memory is based on language, and since language is subjective, the ego does not organize its memory based on free energy hierarchy since our memory is all over the place. This has the value of our memory being reorganized by the inner self; creative and spiritual changes based on free energy.
As an analogy, computer or semiconductor memory is designed to be stable. We can place memory in any order, objective or subjective, and it stays that way. Picture if we used more fluid and reactive memory that can self catalyze and rearrange based on free energy. Changes will follow the laws of physics instead of the subjective standards of man. Such memory would rearrange in situ. This may appear scrambled or randomized to the ego, but it would be the language of nature and inner self. Dreams and visions are often the inner self reorganizing human memory which is often the foundation of many religions; prophets.
