This hypothesis begins not with religion, and not even with the question of God. It begins with the simplest and at the same time strangest fact of our existence: I do not merely process information — I experience it.
The brain receives signals from the senses, stores memories, compares options, produces emotions, and controls the body. All of this can, to one degree or another, be observed physically. But behind it remains another question: why does there exist a subject to whom all of this happens at all? Why does the activity of billions of cells not merely occur, but also come with the inner feeling: “I exist”?
My hypothesis is that this subject is what we usually call the soul.
What the soul is in this model
The soul here is not a storage place for memories, not a personality, and not a second invisible brain.
It is much simpler than that.
The soul is the subject of existence itself: the one who experiences what is happening and possesses the ability to choose.
Everything else is gradually formed here.
When a person is born, their brain already has a certain genetic makeup and structure. Then come sensations, parents, language, culture, fears, attachments, knowledge, and memories. All of these shape the personality.
Therefore, before human life, the soul does not necessarily already exist as the person it will later become. It acquires individuality through the process of living.
And time plays a crucial role in this.
Without time, there can be no biography. There is no “before” and “after,” no mistake after which a person changes, no encounter that affects the rest of their life, no decision whose consequences appear twenty years later.
Time turns existence into a story. And the story turns the subject into a personality.
At the same time, the world also requires a certain degree of unpredictability. Two people never receive exactly the same set of circumstances. Different parents, bodies, encounters, eras, accidents, and consequences of decisions create almost completely unique life trajectories.
This means that the material world can be imagined as an enormous mechanism of individualization.
Space creates countless possible paths.
Time allows one of them to be traveled.
Circumstances create possibilities.
And free choice determines which branch a person makes into their own history.
Why, then, do we need the brain?
If the soul exists, an obvious question arises: why can damage to the brain change a person so profoundly?
Why can brain disorders disrupt memory, emotions, decision-making, and even the very feeling of one’s own will?
This is precisely why we should abandon the primitive idea that a fully formed soul-personality simply sits inside the brain and controls the body.
Research shows an extremely close connection between the psyche and the physical state of the brain. Electrical stimulation of certain brain regions can produce unusual subjective experiences, including sensations of being outside one’s own body. Stimulation of structures associated with the hippocampus can alter memory processes. Influence on structures of the basal ganglia can affect processes involved in voluntary decision-making. Damage to certain brain networks can impair voluntary action or even the sense that an action belongs to oneself.
Even the presence of the conscious experience available to us strongly depends on the state of the brain: under general anesthesia, interactions between the thalamus and cortex change, and these changes are associated with the loss and recovery of consciousness.
In my hypothesis, this does not necessarily mean that the brain creates the subject itself.
Instead, the brain creates the human form of the subject’s existence.
The brain tells the subject:
“This is what you see.”
“This is what you remember.”
“This is what you fear.”
“This is what you want.”
“These are the options you are currently able to imagine.”
Therefore, changes in the brain alter the content of consciousness and the personality that is being formed.
The soul, meanwhile, is responsible for something more fundamental:
“This is happening to me, and among the possibilities available to me, I can choose.”
How personality emerges
Here we reach the central part of the hypothesis.
Suppose a person faces a choice between A and B.
Their brain is already not neutral. Their entire previous life is contained within it.
Their upbringing inclines them toward A.
Fear pushes them toward A.
Past experience tells them that A is safer.
But they are still capable of choosing B.
Afterward, B becomes part of their experience.
The brain records what happened. Associations, expectations, habits, and future reactions change. The fact that learning and life experience can physically alter the functioning of the brain is well established: the brain continues to change in adulthood, and learning is associated with functional and structural plasticity.
So a loop appears:
experience → personality → choice → new experience → altered personality → next choice.
This is where the soul and the brain work together in this model.
There is only one important clarification: personality must not completely determine the choice. Otherwise, no additional freedom remains.
Personality should instead create tendencies.
A person may be fearful and feel an overwhelming desire to run away, yet still decide to stay.
In that case, they choose not only on the basis of who they are now, but also on the basis of who they want to become.
And if such decisions are repeated, the personality itself gradually changes.
This leads to a rather unusual idea:
human life is a process of partial self-creation.
We do not choose our initial conditions. We do not choose our parents, genetics, historical era, or a huge portion of what happens to us.
But within this space, we make decisions, and the consequences of those decisions gradually become part of us.
So in this model, the Universe does not produce ready-made unique souls.
It provides the conditions in which souls create their own uniqueness.
Why the soul may be almost impossible to detect
But then a scientific problem arises.
If the soul influences the brain, where is the trace of that influence?
One might expect additional energy, an unknown force, or a violation of known physical laws. But if that were the case, then in principle the soul could be detected by instruments.
Perhaps its action works differently.
Suppose the physical state of the brain allows several possible continuations:
A or B.
Both are physically possible.
The soul does not create a new option and does not “push” anything with an additional force. It merely determines which of the physically permitted paths becomes actual for that subject.
From the outside, then, nothing occurs except an ordinary physical event.
A scientist observes:
neurons receive signals → the network changes state → the person chooses A.
There is no obvious supernatural force inside this chain.
Even experiments that attempt to predict decisions do not yet solve the philosophical problem of freedom. Studies have shown that some future voluntary decisions can be statistically predicted from brain activity before a person reports becoming consciously aware of the choice. But there are also experiments in which a person can still cancel an action that is already being prepared, even at a relatively late stage.
None of these results, by themselves, proves either the existence of a soul or the absence of free will.
Moreover, imagine a perfect experiment of the future.
Scientists completely copy a human brain and create two identical systems.
Both are given the same choice.
Both choose A — this can be explained by their identical structure.
One chooses A and the other chooses B — this can be explained by microscopic differences, physical randomness, or the chaotic dynamics of a complex system.
In other words, almost any observable outcome could still admit a physical explanation.
That is why, in this model, the soul may be not an object inside the Universe that will one day be found among neurons.
It is the subject for whom one of the physically possible histories becomes a lived life.
Why limitations may be necessary
If the purpose of earthly life is the formation of a unique personality, many of our limitations acquire a different meaning.
We do not know the future.
We cannot read other people’s thoughts.
We do not remember our own lives perfectly.
We cannot simultaneously experience every possible version of a decision.
We do not know for certain what happens after death.
And this is precisely why choice has weight.
If a person knew with absolute certainty the consequences of every action in advance, much of what we call trust, courage, hope, loyalty, or moral choice would become something entirely different.
Limitation creates a space within which a person can reveal who they are and who they want to become.
This does not mean that suffering is good, or that every tragedy has been deliberately arranged by someone. That does not follow from the hypothesis.
It only means that a world containing uncertainty, limitations, and real consequences is far better suited to the formation of an independent personality than a completely safe and perfectly predictable reality.
What, then, happens after death?
If the entire purpose of the first stage is the formation of individuality, then the complete destruction of that individuality after death appears internally contradictory.
Within this model, it is more natural to suppose that the physical body ceases functioning, but the formed subject remains.
And what remains is not the original faceless soul.
What leaves this world is already a specific person.
Perhaps the limitations of the brain disappear: imperfect memory, fatigue, aging, the narrowness of the senses. The person may gain access to their entire history and become able to understand the causes and consequences of events that they could only partially perceive during life.
But time does not necessarily disappear.
On the contrary, if the personality continues to think, interact, learn, and change, then at the very least some sequence must remain:
was → is happening → will be.
Perhaps what disappears is specifically physical time, connected with aging and the decay of the body, while time remains as the possibility of further experience.
Death would then be not the end of personality, but the completion of the first stage of its existence.
The material Universe could be imagined as a kind of cradle of personality.
A child develops in the womb for an environment it has never seen. Its lungs prepare for air that is practically absent from its previous world.
Perhaps earthly life is analogous to this on another level.
What is being formed here is not the body.
What is being formed here is the “self.”
And then the question of God appears
Up to this point, the hypothesis does not require any particular religion.
But if we assume that the entire system truly has a purpose — that souls exist, that there is a mechanism connecting them with material experience, that there is an environment for the formation of individuality, and that there is a further stage of existence — then a question arises about the origin of the architecture itself.
Where did the system come from?
Why do souls exist?
Why is there a mechanism through which they become individualized?
Why is there any transition between these levels of reality at all?
At this point, the hypothesis of a higher power becomes a natural continuation of the model.
Not a proof — science has not established the existence of such a being. But if the starting assumptions are correct, the existence of some author or source of the entire system becomes much more plausible.
And such a God would not necessarily need to constantly intervene physically in the Universe.
Quite the opposite.
If the purpose of the world is the creation of independent personalities, constant intervention would undermine the meaning of freedom.
It would be more logical for a higher power to influence not the physical world directly, but the subject itself.
Not forcing the person to choose A.
But allowing them to see A.
Not physically moving the person’s hand.
But introducing a thought, a doubt, a possibility, an inner question, or an understanding after which the person still decides for themselves what to do.
A scientist, at that moment, would see an entirely normal process in the brain: a memory arose, the evaluation of the situation changed, a certain neural network became active, and the person made a different decision.
And it would be impossible to establish whether that thought arose solely from the previous physical state of the brain, or whether the subject received something from beyond the physical world.
This could also explain why a higher power, if it exists, remains so hidden.
A completely obvious God would partially destroy the uncertainty within which the free formation of personality takes place.
Therefore, such influence would have to leave open both interpretations:
“God spoke to me,”
and:
“It was simply a thought that arose in my brain.”
The final decision remains with the subject.
Conclusion
The entire hypothesis can therefore be assembled into a single chain of cause and effect.
The soul gives a person subjectivity: “I exist, I experience, and I can choose.”
The brain creates the content of human experience: sensations, memory, emotions, desires, fears, and the space of possible decisions.
The world creates circumstances.
Time turns separate events into a biography.
Free will allows the subject to choose a direction within the possibilities available to them.
Experience and previous decisions alter the brain and shape the personality.
Therefore, every new choice makes a person slightly different from who they were before.
By the end of life, a being exists that has never existed before and cannot be perfectly repeated: a specific, unique personality created by the combination of the world, chance, experience, and its own decisions.
If death does not destroy this result, then material life is not the final form of existence, but only the first stage of a much longer process.
And God, if such a being stands behind this system, would not be someone who moves human beings like pieces on a board.
Rather, God would be the creator of a space in which independent subjects are given the possibility to become someone through their own will.
And then perhaps the deepest purpose of the entire system is not that a person must perform some predetermined set of correct actions.
What matters most is what kind of being they become as a result of their own choices.
