You as a person are the product of your mind. Your mind is what is going on in your brain. Whether the brain is the recipient or the generator of the mind is debatable but this is not relevant to us here.
The brain is the physical organ, the mind is the product of its activity. To understand how the mind works, you need to understand how the brain works.
Neurology made tremendous progress, identified many parts of the brain, and associated them with behaviors and body functions. Alas, this is almost useless to lay people in search of a better life, because it is often too complicated, there is too much to know and we cannot pronounce most of it.
Moreover, It is a scientific fact that every section of the brain is actually linked to most of the other sections. Neurologists are also constantly discovering new relationships inside the brain.
Since our purpose is not to cure diseases but to have a basic understanding of what is going on in our head, this post will be based on what I call my Simplified Brain Theory.
The works of prominent philosophers, scientists and psychologists such as William H. Calvin, Bill Williams, Paul D. MacLean. or Daniel Kahneman have been condensed into three simple building blocks with basic properties. All you will have to learn to understand your mind is how these building blocks interact with each other in addition to a few precepts.
I divide the nervous system into 3 sections. Remember that this division is a simplification of the actual anatomy of the brain.
This includes the cerebellum, the brain stem, the spine and all the nerves throughout the body.
Mostly composed of the Limbic system – Thalamus, cingulate, amygdala, etc.
The neocortex, front lobes, parietal lobes, etc.
Precept: The brain only exists to increase the odds of survival
Brain 1 is in charge of everything related to the body such as temperature, fluids, digestion, hormones, heartbeat, breathing, motor skills, or balance.
Brain 1 is on a constant alert, checking every body fluid level, the heartbeat, the status of every organ, the input from the senses, etc.
Would Brain 1 stop working for a short instant, you would be dead.
Brain 1 takes its information from
Facing a situation, each part of the brain makes a positive or a negative assessment
Brain 1 makes use of physical information to make that assessment
Brain 1 takes a direct action in presence of a situation. Reflexes are a good example
Brain 1’s memory is limited to what the body needs to react to. This is what we call muscle memory
Brain 2 is checking things outside of the body. Landscape, vegetation, and other beings that are around. It is constantly checking its surroundings for good and bad news. Brain 2 is aware of its environment.
Brain 2 takes its information in bulk.
It perceives things in their totality. All the information related to something – smell, view, sound, air temperature, etc. is assembled into one global package -an image- and perceived all at once in a bulk sensation called a feeling
Information is remote – away from the body.
Precept: Brain 2 is the brain of intuition and happiness
Because it looks at things from a remote position, and unlike Brain 1 which is reacting by taking direct action, Brain 2 can make decisions in presence of a situation.
Brain 2 associates an image (bulk information) to a feeling (bulk sensation) and stores this binary information in memory. This is often called conditioning and has been described in details in the work of Pavlov or Bergson.
Brain 3’s world is totally abstract.
It is constantly comparing past memories, current information, and future projections.
It is the siege of reflection and all cognitive functions.
Precept: Brain 3 does not live in reality
Brain 3 is the part of the brain that is conscious. Because it handles past, present and future images, it has to keep track of which one is associated with the present moment. This tracking makes it conscious.
Brain 3 takes its information from Brain 1 (physical sensation), Brain 2 (feeling) and also mostly its own memory
This information will trigger a reflection.
But coming up with an answer is not the end
Brain 3 evaluates its own findings accordingly to a ranking system
This ranking system has many particularities:
Ultimately, Brain 1 is taking action.
If the current situation is a body emergency, such as a burn, Brain 1 will take direct action – This is what we call a reflex.
If the current situation involves urgent remote information, such as a threat, Brain 2 will assess it and will emit a negative feeling – fear, make a decision – fight or flight, then pass the decision to Brain 1 which will read it as if it came from external stimuli.
Everything else ends up being treated by Brain 3 and the result of its reflection is passed to Brain 2 which will evaluate it – from fearful to uneasy to content, make a decision about it, and let Brain 1 carry the actual action.
This simple process can create very complex behavior
Also, because they are all physically linked, each part of the brain passes and receives information from the other two parts.
As much as this fact has its convenience, it also has a major flaw, since where the information originated from is unknown to the recipient.
Precept: Brain 1, 2 and 3 cannot differentiate where their information comes from
When Brain 2 feels fear, it does not know if it comes from the sight (Brain 1) of a sabertooth tiger or a threatening email (Brain 3).
To Brain 2, both feel the same way.
Brain 1 keeps the body alive and for that purpose, the cost of survival is no object.
Brain 1 is solely dealing with current situations with a total disregard for future consequences.
For instance, in case of extreme cold, the blood will be recalled to the core of the body, leaving the limbs exposed to dying for lack of oxygenation. This is how frostbites happen.
Brain 1 reacts directly to a stimulation by taking action.
These two simple reactions -reflexes- are going a long way in the matter of survival.
Remember that Brain 2 processes information in bulk. Some of these bulk images are:
Brain 2 can read a situation from afar and feel content or fearful about it.
But it can also read what another individual feels
Precept: Brain 2 can feel what another individual feels
Negative feelings will generate a certain set of body reactions, such as freeze, cramp, or tension. These cues are read by Brain 2 the same way it would read any situation.
Over time, Brain 2 learned to associate such cues to bad news and bad feeling through its conditional memory.
Animals -including humans- equipped with a Brain 2 apparatus are capable of compassion
Compassion leads to caring.
Brain 2 is a major advance in the matter of survival of a species.
This constant interaction within the group is creating a new feeling called connection. For higher forms of life, connection is directly linked to survival, especially when young, hurt, or otherwise dependent on the care of others.
Brain 2 is constantly maintaining an awareness of its surroundings.
Precept: Connection is essential to human life
Brain 1 may not realize that the negative feeling perceived by Brain 2 (the lack of connection) is not a direct physical threat and will engage in a strict survival mode.
As previously seen, the cost of survival is no object. Brain 1 will cut its losses without a flinch.
People with a lack of connection will be sickly and may eventually die.
Sudden Infant Death Syndrome is linked to the lack of Connection.
— Lewis et al – General Theory of Love.
Brain 3 likes to solve problems because solving problems feels good. Being stuck feels bad
You cannot improve what you cannot measure, so in order to resolve a problem, Brain 3 has to compare images of the current situation with past memories and future projections using its ranking system.
The memory of the good feeling of resolving a problem creates something to strive for.
The other two Brains are only responding to what is happening to the body or in the environment
Desire is focused attention to obtain a good feeling.
Rules are preset solutions
We spend most of our waking time in Brain 3 mode. Yet to feel happy, we need to be in Brain 2 mode.
Remember that Brain 3 is working out of memory or other abstract projections. Nothing of what it thinks has a ground in the current reality.
These three building blocks, their functions, and their precepts will help you understand a lot about the mind and its mysteries.
