A
How Did Human Consciousness Originate?
Part 1: Paraphrasing the original argument
The passage proposes that consciousness is not a permanent or fundamental feature of existence but rather a temporary state that emerges from a deeper, continuously operating unconscious process.
Conscious awareness appears and disappears. For example, when we fall asleep, lose consciousness under anaesthesia, or enter dreamless sleep, our conscious experience diminishes or vanishes. Yet the brain remains remarkably active, maintaining the body, regulating biological functions, processing information and performing numerous operations outside conscious awareness.
This suggests that consciousness and the unconscious serve fundamentally different purposes.
We might understand their relationship through a cinematic analogy:
The unconscious is the film producer: It works continuously behind the scenes, organising information, managing resources, constructing experiences and maintaining the entire production.
The conscious mind is the audience: It experiences the finished presentation without necessarily knowing how it was created.
The passage then introduces a Hindu philosophical interpretation.
It compares the collective unconscious to Brahman, the ultimate underlying reality, and the collective conscious to Atman, the individual experiencing self.
The central question consequently becomes:
How does the underlying, unconscious reality give rise to conscious experience?
The author's proposed explanation is that the underlying reality operates through logic and mathematics, while consciousness emerges when this underlying information is translated into geometry, light, colour, shapes and perceptual experience.
In other words, the unconscious operates through hidden informational processes, while consciousness experiences their output as a vivid, meaningful world.
The brain provides an analogy: electrical and chemical activity occurs inside the darkness of the skull, yet our conscious experience presents us with sunshine, flowers, colours, landscapes and sounds.
The author is essentially suggesting that consciousness is the transformation of an invisible informational reality into an experienced phenomenal reality.
Part 2: Deep dive into the major points
1. Consciousness comes and goes: Does that mean it is not fundamental?
This is the first and perhaps most important philosophical claim.
Consciousness appears to fluctuate:
We are awake and consciously aware.
We dream and experience an alternative form of awareness.
We enter deep, dreamless sleep.
We lose consciousness under anaesthesia.
We regain awareness when the relevant brain processes recover.
Meanwhile, many biological and neural processes continue.
The author draws the conclusion that consciousness cannot be fundamental because it is intermittent.
However, this conclusion needs qualification.
Something disappearing from experience does not necessarily mean that its underlying capacity or foundation disappears.
Consider a television:
The picture can disappear.
The electrical system remains operational.
The signal-processing infrastructure may continue functioning.
Similarly, consciousness might be a temporary expression of deeper processes rather than an independently existing substance.
There are at least three philosophical possibilities:
Emergent consciousness: Consciousness emerges when biological systems reach a particular level of organisation.
Fundamental consciousness: Consciousness is a basic feature of reality, although individual conscious experiences can disappear.
Consciousness as information integration: Consciousness arises when information is organised and processed in particular ways.
The important distinction is between consciousness as an underlying possibility and consciousness as an actual experience.
These are not necessarily the same thing.
2. The unconscious is not inactive: It is the hidden operating system
The passage makes a valuable observation: unconscious activity is enormously extensive.
When you are not consciously thinking about your body, your brain and nervous system continue to:
Regulate breathing.
Control heart rate and blood pressure.
Coordinate digestion.
Regulate temperature.
Consolidate memories.
Process sensory information.
Coordinate movement.
Monitor the internal environment.
Respond to potential threats.
Even when you are asleep, your brain is actively involved in memory processing, metabolic regulation and other functions.
This leads to an interesting distinction:
The conscious mind does not run the entire organism. It experiences only a limited portion of what the organism is doing.
In fact, conscious awareness may be more like the visible tip of a much larger information-processing system.
An important scientific qualification: the unconscious is not one unified entity with a single agenda. It describes many different processes distributed throughout the brain and body.
Nevertheless, the producer-audience analogy is useful because it highlights the enormous amount of work occurring outside awareness.
3. The movie producer and audience: Two different levels of reality
This analogy deserves closer examination.
Imagine a movie being produced.
Behind the screen, there are:
Scripts.
Mathematical calculations.
Computer-generated imagery.
Lighting systems.
Sound engineering.
Editing.
Production decisions.
The audience does not experience these operations directly.
Instead, it experiences the finished movie.
The author suggests that the relationship between the unconscious and conscious mind is similar.
Unconscious | Conscious |
|---|---|
Processes information | Experiences information |
Performs background operations | Experiences foreground events |
Maintains biological systems | Experiences bodily states |
Processes sensory signals | Experiences colours and sounds |
Operates largely outside awareness | Creates subjective awareness |
The deeper implication is that our conscious world may be a constructed representation rather than a direct experience of underlying reality.
This connects with an important idea in neuroscience: perception is a constructive process.
The brain does not simply photograph the external world.
It combines sensory input, memory, expectations and predictions to construct our experience.
For example, what we experience as colour depends on the interaction between wavelengths of light, the visual system and neural processing.
The redness of a rose is therefore not simply a property existing independently in the brain or the external object. It is part of an interaction between the physical world and the perceiving organism.
This raises a profound question:
If the brain constructs our experienced world, what is the relationship between the underlying reality and the reality we experience?
4. Brahman and Atman: The Hindu philosophical connection
This is where the argument moves from neuroscience into metaphysics.
The author uses two important concepts from Hindu philosophy.
Brahman
Brahman refers, particularly in Advaita Vedanta, to the ultimate, non-dual reality underlying existence.
It is not simply a cosmic unconscious mind.
Brahman is understood as the fundamental reality that transcends ordinary distinctions between subject and object.
Atman
Atman refers to the deepest self or essential nature of an individual.
In Advaita Vedanta, Atman and Brahman are ultimately identical.
This is expressed in the famous philosophical teaching:
Tat Tvam Asi — Thou art That.
The implication is extraordinary.
The individual self, when understood beyond its ordinary psychological identity, is not fundamentally separate from ultimate reality.
However, there is an important distinction between traditional Advaita Vedanta and the author's interpretation.
The passage associates Brahman with the collective unconscious and Atman with the collective conscious.
This is an interesting analogy, but it is not an exact representation of Hindu philosophy.
In particular:
Brahman is not equivalent to the psychological unconscious.
Atman is not equivalent to ordinary conscious awareness.
Brahman is not simply an information-processing system.
Atman is not merely the individual mind observing the world.
The traditional philosophical claim is much more radical: the ultimate reality and the deepest self are not two separate things.
5. The central hypothesis: Logic and mathematics become geometry and light
This is arguably the most original part of the passage.
The author proposes that the underlying reality operates through logic and mathematics, but consciousness experiences that reality through geometry and light.
Let's unpack this.
A. The underlying informational world
The brain contains enormous amounts of electrical and chemical activity.
Neurons communicate through electrical impulses and chemical neurotransmitters.
These processes encode and transmit information.
Yet electrical activity itself does not look like a flower, a sunset or a mountain.
There is no literal sunshine inside your skull.
There are patterns of neural activity.
B. The transformation into subjective experience
The visual system processes information about:
Light intensity.
Wavelength.
Contrast.
Shape.
Distance.
Movement.
Spatial relationships.
The brain integrates this information into a coherent perceptual experience.
The result is a world of:
Colours.
Shapes.
Objects.
Landscapes.
Depth.
Movement.
Beauty.
The author describes this as a transformation from mathematics and logic into geometry and light.
This is metaphorically powerful.
However, science has not established that mathematical information literally transforms into consciousness or that mathematics is the fundamental substance of the unconscious.
C. Why geometry is particularly interesting
Geometry provides the structural framework through which we experience the physical world.
Consider a tree.
Your visual system must construct:
Its outline.
Its spatial position.
Its distance.
Its three-dimensional structure.
Its relationship to surrounding objects.
The brain creates an organised spatial representation from sensory information.
This raises an intriguing possibility:
Our experienced world might be understood as an informational representation organised into spatial and temporal structures.
The question then becomes whether consciousness is simply the representation itself or whether something additional is required to explain the subjective experience of seeing.
That brings us to the central problem of consciousness.
6. The hard problem: Why does information processing produce experience?
Suppose we understand everything happening inside the brain.
We understand:
Every neuron.
Every electrical impulse.
Every chemical reaction.
Every sensory pathway.
Every computational operation.
Would we then understand why seeing red actually feels like something?
This is the famous hard problem of consciousness, associated with philosopher David Chalmers.
The distinction is between:
The functional question: How does the brain process information, recognise objects, control behaviour and integrate sensory information?
The experiential question: Why does any of this processing produce subjective experience?
For example, neuroscience can investigate how the visual system processes a red apple.
But explaining the neural mechanisms does not automatically explain why there is a subjective experience of redness.
This is precisely where the author's theory becomes philosophically interesting.
The author is suggesting that consciousness might be the transformation of underlying informational structures into experienced reality.
But there remains a missing explanatory step:
Why should mathematical or informational structures have an experiential dimension at all?
That is the unresolved problem.
Part 3: Connecting the argument to other major theories
The passage becomes even more interesting when compared with several established philosophical and scientific frameworks.
1. Carl Jung — Collective unconscious
Jung proposed that the human psyche contains inherited archetypal structures that influence experience beyond individual awareness.
This resonates with the author's idea of a deeper unconscious foundation, although Jung's collective unconscious is a psychological concept, not identical to Brahman.
2. Donald Hoffman — Conscious realism
Hoffman argues that our perceptual experience does not necessarily reveal objective reality as it exists independently of observers.
What we experience may be an interface that simplifies a deeper reality.
This closely resembles the producer-audience analogy.
3. John Archibald Wheeler — It from bit
Wheeler explored the possibility that physical reality has a deep informational foundation.
His famous expression, "It from bit", suggests that physical reality may be connected to informational distinctions.
This is conceptually close to the author's idea of underlying mathematical structures giving rise to experienced reality.
4. Giulio Tononi — Integrated Information Theory
This theory proposes that consciousness is associated with the integration of information within a system.
It attempts to explain why certain organised systems might have subjective experience.
It provides a more formal scientific framework for investigating relationships between information and consciousness.
These theories are not interchangeable, and none establishes the author's proposed Brahman-to-Atman mechanism. They do, however, illuminate different aspects of the same underlying question.
Part 4: My deeper interpretation — What is the author really suggesting?
I think the passage can be distilled into one particularly interesting proposition:
Consciousness may be the experiential presentation of a deeper reality that operates outside conscious awareness.
Think of reality as having two levels.
Underlying reality
Brahman / unconscious / information
Hidden processes, relationships, mathematical structures and information
Transformation / manifestation
Experienced reality
Atman / consciousness / perception
Colours, light, geometry, sound, objects, emotions and subjective experience
This interpretation suggests that the universe we experience is not necessarily reality in its ultimate form.
It may be a translation of something deeper into a form that a conscious observer can experience.
There is an important philosophical distinction, however: the diagram represents the author's proposed model, not an established scientific description of how consciousness works.
Part 5: Five questions that take the argument further
These are the questions I believe are worth exploring beyond the original Quora answer.
1. Does the unconscious create consciousness, or does consciousness emerge when unconscious information-processing reaches a particular level of organisation?
2. If mathematics describes the underlying structure of reality, why does that structure become an experience of colour, beauty, emotion and meaning?
3. Is the universe fundamentally mathematical, or is mathematics simply the language human intelligence uses to describe the universe?
4. If Brahman is ultimate reality and Atman is the individual self, is individual consciousness a separate entity or an expression of a universal underlying reality?
5. Could consciousness be less like a product manufactured by the brain and more like a process through which reality becomes experienced?
The fifth question is particularly provocative, but remains a philosophical possibility rather than a demonstrated scientific conclusion.
Final synthesis
The original passage attempts to bridge three seemingly different domains:
Neuroscience: The unconscious brain performs extensive operations outside awareness.
Mathematics and information theory: Underlying processes can be described through structures, relationships and information.
Hindu philosophy: The relationship between individual awareness and ultimate reality can be explored through Atman and Brahman.
Its central intuition is that conscious experience may be the visible expression of something much deeper and largely inaccessible to ordinary awareness.
Perhaps the most profound question is not simply how consciousness originated, but:
How does an apparently unconscious universe give rise to a universe that can experience itself?
That question takes us beyond the mechanics of the brain and into the deepest unresolved territory shared by philosophy, neuroscience, physics and metaphysics.
