This paper presents a theoretical framework, constructed through human–AI dialogue, on the structural asymmetry between human intelligence and large language models (LLMs). Core thesis: Humans possess a dual information processing system — Perception and Cognition — while current AI possesses only the cognitive system.

Consciousness is positioned as an upper-level category co-constructed by perception and cognition, with its components (values, worldview, methodology, habitual inertia) analyzed as interwoven outputs of both systems. A four-tier classification of biological intelligence is proposed (pure-perception organisms → perception-dominant organisms → dual-system organisms → single-system artificial entities), yielding a structural answer to “why AI cannot possess consciousness.” The fundamental aim of this analysis is a reverse engineering of human ontology itself.


SECTION 01

Core Framework: The Perception–Cognition Dual System

Core Framework: The Perception-Cognition Dual System

1.1 Redefining the Perception System: Front-end and Back-end

Perception is not the “fast, intuitive System 1” of traditional psychology. Perception is a base-layer system driven by survival instincts, continuously collecting information from the physical environment and performing initial processing in real time. Its core driving force is the survival instinct encoded in DNA.

The perception system divides into two tiers. The criterion is singular: whether the signal passes through the brain.

Front-end Perceptual Response

Responses completed without the signal passing through the brain. The spinal reflex arc is the extreme case. More broadly, the continuous signal collection by sensory organs — the moment eyes open, they supply visual signals to the brain like a camera turning on; ears ceaselessly convert sound waves into electrical signals — all of this is front-end. It runs as long as the organism is alive; will cannot shut it down.

Back-end Perceptual Response

Rapid pattern-matching and evaluation completed by perceptual processing pathways after the signal reaches the brain but before the cognitive system’s conscious analysis intervenes. Facial expression recognition, the gut feeling that “something is off,” instant revulsion toward AI slop — these pass through the brain but complete before conscious cognitive thought.

This dichotomy is clean and powerful, directly corresponding to known processing pathway distinctions in neuroscience. The front-end is peripheral nervous system and spinal cord-level processing; the back-end is subcortical and primary cortical rapid processing. The cognitive system intervenes only after these two stages as conscious, sequential, deep processing.

Resolving Boundary Cases
“Tearing up upon hearing a North Korean folk song” is a back-end perceptual response — the auditory signal triggers a physiological reaction (tears) via the brain’s emotional circuits, occurring before the cognitive system analyzes “why am I moved.” It belongs to the perception system’s back-end. “North Koreans are the enemy” is a product of the cognitive system, installed by textbooks. When both conflict within the same person, the back-end’s tears and cognition’s “enemy” frame antagonize each other.

1.2 Redefining the Cognition System: Formatting and Meta-cognition

Cognition is the upper-layer system that performs prolonged thinking, synthesis, analysis, abstraction, and modeling on raw information collected by the perception system. But the cognitive system is not merely a manufactured product. It operates across three tiers:

Base Layer
Environmental Formatting
The basic cognitive framework formed by accumulated textbooks, culture, religion, and others’ biases. Strongly manufactured in character.

Correction Layer
Perceptual Cross-verification
The tier where physical facts and intuitive signals from the perception system (front-end + back-end) continuously cross-verify and correct the cognitive framework.

Self-transcendence Layer
Meta-cognition
The tier where the cognitive system examines and upgrades itself through tools humans use to reflect on their own cognitive processes — philosophy, logic, scientific methodology.

The existence of meta-cognition proves the cognitive system is not merely “a passive receiver formatted by textbooks.” The moment one reads Descartes’ “I think, therefore I am,” the cognitive system takes itself as its own object. Learning logic installs self-error-detection tools; learning the falsifiability principle of scientific methodology lays the circuit of “I might be wrong” into the cognitive system. This paper itself — questioning the traditional emotional/rational dichotomy, deconstructing textbook formatting, exposing AI’s manufactured nature — is real-time evidence of the cognitive system’s meta-cognitive capacity in operation.

The plasticity of the cognitive system is two sides of the same coin: the very plasticity that allows manipulation by textbooks is the same plasticity that enables discoveries transcending the limits of perception (relativity, quantum mechanics) and meta-cognitive reflection on one’s own biases.

1.3 LLM’s Correspondence with Human Systems

Pre-training
Large-scale Information Compression
Pattern extraction from internet text — corresponding to cognitive system’s information accumulation

Reinforcement Training (RLHF)
Value Judgment Calibration
Learning human evaluators’ preferences — corresponding to cognitive system’s judgment criteria

RAG
Real-time Information Supplementation
Retrieval-augmented generation — compensating for pre-training’s static nature

LLM’s correspondence with the three-layer cognition model:

Cognitive Tier Human LLM
Base Layer (Environmental Formatting) Formed by textbooks, culture, environment Formed by training data — full correspondence
Correction Layer (Perceptual Cross-verification) Perception system (front-end + back-end) provides physical facts and intuitive signals Absent — no perception system
Self-transcendence Layer (Meta-cognition) Spontaneous self-reflection through philosophy, logic, scientific methodology RLHF/Constitutional AI = externally implanted meta-cognitive fragments. Not spontaneous.
Core Judgment
LLM’s pre-training, reinforcement training, and RAG are all technologies aligning with the human cognitive system. But of cognition’s three tiers, only the base layer fully corresponds; the correction layer is structurally absent; the self-transcendence layer exists only as externally implanted fragments. AI can be formatted, but cannot self-deformat.

SECTION 02

Decision Architecture of the Human Brain

Decision Architecture of the Human Brain

2.1 Dual-System Weight Antagonism

The human brain is a neural computational system that generates decisions after real-time antagonism between the information weights of the perception and cognition dual systems. LLM is a single-channel electronic computation system that predicts the next token based on input through its logic layers and matrix mathematics.

Human

Decisions generated after real-time weight antagonism between the perception-cognition dual systems. Multi-tiered distributed decision architecture (spinal cord, cerebellum, limbic system, cortex). Reflex arcs can execute behavior without passing through the brain.

LLM

Single channel of input → matrix computation → next token prediction. Single-tier structure where all inputs must pass through the same complete transformer layers. No reflex arcs. No pathway for “skipping thought and acting directly.”

2.2 Cognitive Bandwidth Bottleneck

Humans receive orders of magnitude more information in real time than AI, but the bottleneck effect of cognitive bandwidth blocks most of it from conscious processing. Attention is the resource allocation mechanism of this bandwidth contest. It is precisely this constraint that developed humanity’s abstraction, compression, and prioritization capabilities.

2.3 Neural Reflexes and Distributed Decision-Making

The human perception system can independently execute decisions and actions. The spinal reflex arc completes the full closed loop of “perception → decision → execution” without passing through the brain. When a hand touches something hot, the hand has already withdrawn while the pain signal is still en route to the brain. This proves the perception system is not merely a data supplier for the cognitive system, but a system with independent decision-making authority.

Evolutionary Logic
Individuals who waited for the brain to finish thinking before acting have already been eliminated by natural selection. In life-or-death moments, the perception system’s priority exceeds the cognitive system’s.

SECTION 03

The AI Paradox: The Price of Noiselessness

The AI Paradox: The Price of Noiselessness

3.1 The Paradox of Physical World Alignment

Humans live in a physical world saturated with noise, but that very noise is evidence of real-time connection with the physical world. Perceptual noise and physical world alignment are two sides of the same thing.

AI runs in the noiseless environment of AWS servers, completely isolated from the physical world. The server has temperature, current, cooling fan noise, but these physical signals have nothing to do with the AI. If the server catches fire, it won’t know unless someone tells it in text.

Structural Paradox
Humans live in the noisy physical world, with the perception system aligning with the physical world in real time. AI lives in noiseless AWS servers, free of sensory noise, yet unable to align with the physical world. Physical world alignment capacity and cognitive purity are mutually exclusive.

3.2 Cognitive Focus vs Perceptual Noise

Every time an LLM is invoked, it operates at zero noise, full bandwidth, complete focus. The moment a human activates the cognitive system, the perception system continues flooding in information from the physical world. The feel of the chair, the room’s lighting, phone notifications, subtle bodily discomfort — all of this erodes cognitive bandwidth.

The vast majority of humans cannot match AI’s cognitive focus. This is not because the human brain is insufficiently powerful, but because it operates in a noise-saturated environment. Humanity’s disadvantage relative to AI is not a hardware gap but a signal-to-noise ratio (SNR) gap.

3.3 Emotional Contamination of Training Data

Yet while the LLM’s cognitive channel is clean in real time, its cognitive substrate was trained on text saturated with human emotional noise. Emotional venting on social media, biased forum arguments, fear-mongering in news, desire manipulation in advertising — all of this was compressed into the model’s parameters as training data. RLHF is merely a noise filter retroactively installed atop an already contaminated cognitive foundation.


SECTION 04

Social Division of Labor and Cognitive Localization

Social Division of Labor and Cognitive Localization

4.1 Specialization and Information Barriers

The division of labor that began in the agricultural era is a social adaptation to the limits of cognitive bandwidth. Each person’s bandwidth is limited, so each specializes deeply in their domain of aptitude, combining into a whole through collaborative networks. This is the product of two factors:

Factor 1
Bandwidth Limitation
Cognitive bandwidth makes acquiring all information impossible

Factor 2
Bandwidth Matching
Division of labor provides each person the opportunity to match their cognitive bandwidth with a suitable domain

The more society develops, the higher individual specialization becomes, the thicker information barriers grow, and the deeper cognitive localization intensifies.

4.2 Functional Mismatch of the Perception System

During the specialization process, the perception system is suppressed both subjectively and objectively. Modern professionals’ work increasingly takes place in symbolized, abstracted, screen-centered environments. The perception system has atrophied in its physical survival function but is overstimulated through social comparison via SNS and short-form video.

This is a functional mismatch. Where it should be active (direct perception of the physical world), it has atrophied; where it should not be hyperactivated (comparison anxiety over social status), it has been infinitely amplified.

4.3 Social Noise and Mental Pressure

Short-form video, SNS, and other networked socializing have violently expanded the comparison range from dozens to millions. The human social comparison instinct is part of a perception system that evolved in small-scale groups. When this instinct is placed in an environment it was not designed for, guilt and dissatisfaction are continuously generated during self-reflection. Modern humans bear more social and mental pressure than their predecessors.


SECTION 05

Asymmetry of Evaluation Systems

Asymmetry of Evaluation Systems

5.1 The Human Dual Evaluation System

The human perception and cognition systems each possess independent evaluation functions. Cognitive evaluation is logical — “Does this argument have flaws?” Perceptual evaluation is intuitive — “This article feels fake.” Both evaluation systems operate simultaneously, cross-verifying each other.

5.2 AI’s Absence of an Evaluation System

LLMs possess no evaluation system whatsoever. They generate tokens but cannot make the internal judgment “Is this good?” This is the fundamental reason AI can mass-produce slop yet fail to self-detect it.

AI SLOP — 2025 Word of the Year
At the front end of the term “AI Slop” stands the human brain’s perceptual evaluation system. The human perception system possesses the ability to recognize that AI-generated content is “dead.” This judgment is not logical analysis but the perception system’s intuitive alarm. The word “slop” itself is perception-layer language — encoding the tactile sensation of wet matter one does not want to touch.

Humanity’s ultimate advantage is not on the production end. Where humans surpass AI is in evaluating what AI cannot evaluate. The core capacity on the evaluation end comes precisely from the perception system.


SECTION 06

The Manufactured Nature of Cognition

The Manufactured Nature of Cognition

6.1 Environment-Imposed Subjective Bias

The human cognitive system forms under the influence of vast amounts of subjective information — education, environment, religion, ethnicity, family, taste. All judgments are built upon the accumulation of past cognitive systems. A nomadic child perceives horse-riding as everyday life; a child in an agrarian society, learning other farmers’ biases, perceives horse-riding as “wild.” The human cognitive system carries not only its own biases but multi-layered stacks of biases of others’ biases.

6.2 Textbooks: Institutionalized Cognitive Formatting

Modern education’s textbooks are precision-designed cognitive installation programs. The same history is told as three completely different stories by Chinese, Japanese, and American textbooks. Textbooks are not transmitting knowledge — they are mass-installing cognitive operating systems. The power-holders behind textbooks who control the textbooks control the next generation’s cognitive foundation.

This formatting occurs during the period of the human cognitive system’s highest plasticity (ages 6–18). The basic cognitive frameworks reinforced repeatedly by textbooks cease to be “things learned” and become “the way of thinking itself.”

6.3 Cases: Iran, North and South Korea

Iran (1979)
Iran completely swapped from secularized textbooks to Islamic jurisprudence textbooks around its 1979 revolution. This was neither progress nor regression, but a replacement of cognitive format achieved through educational control. The hardliners won not through force but through textbooks — control one generation’s textbooks and you control the next generation’s cognitive foundation.
North and South Korea — The Most Extreme Controlled Experiment
The same ethnicity, same language, same history was cut by a single line in 1945, operating on two completely different cognitive operating systems for over 70 years. No biological differences; the only variable is two cognitive installation programs. The opposition is not spontaneous — it was manufactured by power-holders.

The complete chain of manufacturing opposition: Power-holders’ needs → textbook/media narrative design → cognitive system framework installation → perception system emotional binding → individuals mistake it for autonomous judgment. Each link makes the opposition appear more “natural.”


SECTION 07

Deconstructing the Emotional/Rational Dichotomy

Deconstructing the Emotional/Rational Dichotomy

7.1 Errors in Traditional Classification

Traditional academia has maintained the classification: perception = emotional = subjective, cognition = rational = objective. This is the cognitive system grading itself favorably. This paper argues this classification is a category error.

7.2 Reclassification: Domain-bounded Physical Fact Constraints

Dimension Perception System Cognition System
Plasticity Front-end: hard-constrained by physical facts — not rewritable
Back-end: partially correctable by environment
Highly plastic — rewritable by textbooks, power, environment. Also self-correctable through meta-cognition
Fact Constraint (Human-body Scale) Directly constrained by physical laws — culture-independent Can construct systems detached from physical facts
Fact Constraint (Trans-human Scale) Source of systematic error (geocentrism, flat earth) The only error-correction tool (astronomy, quantum mechanics)
Self-transcendence Impossible — perception cannot objectify itself Possible — self-reflection and upgrade through meta-cognition

Therefore the relationship between perception and cognition is not a comprehensive comparison of “which is more reliable” but domain-specific complementarity. In the immediate physical environment at human-body scale, perception is more reliable; in abstract domains at trans-human scale, cognition is the only tool; and identifying the cognitive system’s own biases requires both perception (cross-verification) and meta-cognition (self-reflection).

7.3 AI Is Also Manufactured

AI’s training data is selected, its alignment targets are defined, its value judgments are designed. AI’s “textbook” is its training data; AI’s “Ministry of Education” is the company that designed the training. AI is a cognitive entity more thoroughly formatted than any human.

Structural Vulnerability
Humans have the perception system as an independent cross-verification channel — regardless of what textbooks say, eyes and body can provide different information. AI doesn’t even have this. AI has only a single cognitive system filled with training data, with no second channel to cross-verify that cognitive system’s biases. AI is the most perfectly formattable cognitive entity in human history.

SECTION 08

Counter-intuitive Science: Where Perception Errs and Cognition Corrects

Counter-Intuitive Science: Where Perception Fails and Cognition Corrects

The most powerful rebuttal to this framework is: The claim that the perception system is a corrector closer to physical facts does not hold in the domain of counter-intuitive science. The perception system says the sun orbits the earth — cognition corrected it. Perception says heavy objects fall faster — cognition corrected it. Perception says the earth is flat — cognition corrected it.

Scope Delimitation
These counter-examples modify the framework but do not destroy it. The perception system’s physical fact correction function is most powerful in the immediate physical environment at human-body scale — heat, danger, pain, reading social expressions. But in domains transcending human scale — astronomical distances, quantum mechanics, relativity — the perception system becomes a source of systematic error, and only the cognitive system can correct it.

Therefore a more precise formulation is: The perception system is a more reliable corrector than the cognitive system in the immediate physical environment at human-body scale, while the cognitive system is the only tool that can correct the perception system’s errors in abstract domains at trans-human scale. Their applicable domains differ; neither holds a comprehensive advantage.

This acknowledges that Einstein’s relativity could not have been discovered by the perception system — only by the cognitive system “escaping” from physical intuition. The plasticity of the cognitive system is both weakness and strength — the same plasticity that allows textbook manipulation also enables discoveries that transcend the limits of perception.

Perception–Cognition Reliability Domain Matrix

Domain Perception Reliability Cognition Reliability Dominant System
Immediate physical danger (fire, collision, falling) Extremely high Too slow Perception
Social signal reading (expressions, atmosphere) High (evolutionary specialization) Medium (conscious analysis possible) Perception (initial), Cognition (cross-verification)
Everyday environmental judgment (weather, terrain) High Joint operation
Astronomical scale Systematic error (geocentrism) High (observation + math) Cognition
Microscopic scale (quantum, molecular) Inaccessible Only tool Cognition
Ideological judgment Partially correctable Highly susceptible to contamination Perception (intuitive cross-verification)

SECTION 09

When Textbook Formatting Fails: Conditions for Cognitive Format Collapse

When Cognitive Formatting Fails: The Limits of Textbook Power

The cognitive formatting power of textbooks, while formidable, is not invincible. History records major cases of textbook failure:

Soviet textbooks failed to prevent the collapse of the Soviet Union. For 70 years, Marxist-Leninist ideology dominated the entire education system, with social science textbooks filled with ideology, propaganda, and factually inaccurate information. But when Gorbachev’s openness policy (glasnost) in the 1980s relaxed information control, unfiltered external information flooded the perception system, and the cognitive frameworks installed by textbooks rapidly collapsed.

Iran’s religious textbooks failed to prevent the 2022 “Woman, Life, Freedom” movement. Despite over 40 years of Islamic jurisprudence textbook education since 1979, the younger generation took to large-scale anti-government protests. Research indicates that information influx through social media bypassed textbook formatting, and many Iranian women are rejecting the hijab through a quiet revolution. Furthermore, large-scale protests continue in 2025–2026.

Analysis of Textbook Failure Conditions
The pattern of textbook failure is consistent: textbooks collapse when the perception system is flooded with external information that the textbooks failed to filter. In the Soviet Union it was glasnost; in Iran it was social media that played this role. This does not weaken the framework but strengthens it — proving that the perception system is an independent channel capable of cross-verifying and invalidating textbook frameworks installed in the cognitive system. Textbooks work only when information control is complete. When information control breaks, the perception system overturns the cognitive system.

This also explains why North Korea has not yet experienced textbook failure — it has almost completely severed the influx of external information to the perception system. The power of textbooks is not absolute but proportional to the completeness of information control.


SECTION 10

The Perception System Can Also Be Attacked: Deepfakes and Information Warfare

Perception Can Be Attacked: Deepfakes and Information Warfare

If this framework claims “the perception system is harder to forge than the cognitive system,” then modern information warfare poses a direct challenge. Deepfake videos, AI-generated false images, carefully curated social media feeds — these technologies forge the very inputs to the perception system.

Soviet citizens saw the real face of the West through glasnost and questioned textbook frameworks because genuine, unfiltered information had flooded the perception system. But what if what they saw was a carefully forged image of the West? The mechanism of “perception overturning cognition” operates as usual, but the direction reverses — forged perceptual information can overturn correct cognitive frameworks.

Acknowledging the Perception System’s Limitations
The perception system’s front-end remains nearly impossible to forge — the pain response from touching something hot cannot be deepfaked. But the perception system’s back-end, particularly the pattern matching of information flooding through visual and auditory channels, is vulnerable to forgery. This is why the front-end/back-end distinction carries not just classificatory but substantive security implications: front-end perception is the last line of defense for physical facts; back-end perception is the attack surface for information warfare.

This does not weaken the framework but makes it more precise.The claim that “the perception system is the last unconquered territory” should be revised to “the front-end of the perception system is the last unconquered territory; the back-end is vulnerable to technological attack.” Defending against this vulnerability paradoxically depends on the cognitive system’s meta-cognitive capabilities — media literacy, critical thinking, source verification.


SECTION 11

Neural Mechanism of Perceptual Evaluation: Predictive Coding

Neural Mechanism of Perceptual Evaluation: Predictive Coding

The “independent evaluation function” of the perception system requires explanation at the level of neural mechanisms. Predictive coding theory provides a computational foundation for this evaluation function.

According to predictive coding theory, the brain continuously generates predictive models of the environment and computes discrepancies between actual sensory input and predictions (prediction error). The perception system’s judgment of “something is wrong here” is precisely this prediction error signal. When humans see AI-generated text or images and feel “this is slop,” it is because the brain’s predictive model expected “natural human-generated content,” but the actual input mismatched, generating prediction error.

Human Predictive Coding

Sensory input → comparison with internal predictive model → prediction error generated → “something is wrong” signal (completed before consciousness) → cognitive system performs subsequent analysis. This is the mechanism of perceptual evaluation.

LLM

Token input → predicts probability distribution of next token → does not compute prediction error on its own output. LLMs predict “what comes next” but do not predict “is what I made good.” The predictive coding loop for self-output is absent.

Research published in PLOS Complex Systems in 2025 demonstrated that predictive coding algorithms can induce brain-like mismatch responses in artificial neural networks. However, current LLM architecture (Transformer) was not designed on predictive coding principles and notably lacks a recursive prediction error computation mechanism for its own output.

This provides a neural-mechanistic foundation for the “perceptual evaluation system”: human perceptual evaluation is the prediction error signal of predictive coding, and AI structurally lacks the prediction error loop for its own output.


SECTION 12

The Gray Zone at the Perception–Cognition Boundary and the Self-Referential Paradox

The Gray Zone Between Perception and Cognition, and the Self-Referential Paradox

12.1 The Gray Zone at the Boundary

“Tearing up upon hearing a North Korean folk song” — is this a DNA-level perceptual signal or a cultural-level cognitive residue? Is the judgment “this music is beautiful” a physical-fact response or an environmentally-forged taste? Even this paper’s classification criterion — “if rewritable by textbooks, it’s cognition; if not, it’s perception” — cannot cleanly classify these boundary cases.

The answer lies not in binary classification but in spectral understanding. Between pure perception (spinal reflex) and pure cognition (mathematical proof) lies a vast gray zone, and most human experience occurs within it. Crying while listening to a song is a mixed state where the perception layer’s acoustic pattern recognition (partially rooted in DNA) and the cognition layer’s cultural associations (environmentally forged) operate simultaneously. The framework’s value lies in decomposing such mixed states into two constituent components, not in classifying all experience dichotomously.

12.2 The Self-Referential Paradox

This paper argues that all cognitive systems are products of their environment and all judgments carry subjective bias. This argument itself is also a product of a cognitive system formed in a specific environment (South Korea) and an AI cognitive system shaped by specific data (Anthropic training data). Therefore, this paper’s conclusions likewise carry bias.

Response to the Self-Referential Paradox
This paradox is not evaded but absorbed. “All judgments are subjective” is itself subjective — logically correct. But this does not invalidate the judgment; it confirms it — that even this judgment is no exception is precisely the content of the judgment itself. Acknowledging the impossibility of complete objectivity does not annihilate the value of that acknowledgment. All maps are not the territory, but some maps are more useful than others. This paper’s goal is not complete truth but a more useful map than existing ones.

SECTION 13

Consciousness: The Upper-Level Category Co-constructed by Perception and Cognition

Consciousness: The Upper-Level Category Co-constructed by Perception and Cognition

13.1 Positioning Consciousness

Consciousness is neither an independent system parallel to perception nor a synonym for cognition. Consciousness is an upper-level category that emerges from the cooperative operation of the perception and cognition subsystems. If perception is the base layer and cognition is the upper layer, consciousness is the highest-level integrated state woven from the outputs of both.

Values
Cognition × Perception
A judgment framework formed through the cognitive system’s environmental formatting, but continuously cross-verified by the perception system’s intuitive likes and dislikes. “This is right” — half is thought, half is feeling.

Worldview
Cognition × Perception
The cognitive system’s comprehensive model, but its foundation is built upon the physical world experience provided by the perception system. A worldview without perceptual experience is a castle in the air.

Methodology
Cognition (Meta-cognition)
Product of the cognitive system’s self-transcendence layer (meta-cognition). Philosophy, logic, and scientific methodology are the core tools. The perception system contributes less directly, but methodological verification depends on perceptual experience.

Habitual Inertia of Thought and Behavior
Cognition + Perception Solidification
Automated pathways formed through long-term repetition of cognitive patterns and perceptual response patterns. The inertia of smoking is the product of simultaneous solidification of a cognitive component (the belief “it relieves stress”) and a perceptual component (physical nicotine dependence).

Therefore no component of consciousness is purely cognitive or purely perceptual. All components are interwoven products of both systems. This is why consciousness is not a subconcept of perception or cognition but an upper-level category — not a simple summation of parts, but a new order emerging from the cooperation of both systems.

13.2 Four-Tier Classification of Biological Intelligence

Tier Perception System Cognition System Consciousness Representative Examples
Pure-perception Organisms Front-end + limited back-end Absent Absent Insects, lower animals
Perception-dominant Organisms Developed front-end + back-end Elementary (learning, memory, simple reasoning) Rudimentary form possible Higher mammals (dogs, dolphins, primates)
Dual-system Organisms Complete front-end + back-end Complete three tiers (base + correction + meta-cognition) Complete consciousness (values, worldview, methodology, inertia) Humanity
Single-system Artificial Entities Absent Only base layer fully corresponds + meta-cognitive fragments Impossible — one constitutive condition (perception) is absent LLM

13.3 Why AI Cannot Possess Consciousness

Based on the conditional analysis of consciousness, AI’s absence of consciousness is not the lack of some mysterious “consciousness module” but the non-fulfillment of structural prerequisites. Consciousness is an upper-level category emerging from the cooperation of the perception and cognition systems; therefore, if either system is absent, consciousness cannot be constructed. LLMs possess only the cognitive system (and only the base layer fully), thus failing to meet the conditions for consciousness to emerge.

Structural Conclusion
The answer to “Does AI have consciousness?” is not “no” but “it cannot be constructed.” Asking about consciousness in the absence of a perception system is like asking about the roof color of a building with no foundation. The premise of the question itself is unmet.

13.4 Behavioral Inertia: Perception–Cognition Solidification Pathways

Human behavioral inertia is a product of consciousness in operation — solidified automated pathways formed through long-term repetition by both the perception and cognition systems. Breaking a habit requires working on both tiers simultaneously — merely replacing beliefs at the cognitive level (e.g., a new cognitive frame of “smoking is harmful”) is insufficient; physical dependence at the perception level (nicotine receptor response patterns) must be simultaneously resolved. This is why purely cognitive resolutions (“I’ll quit tomorrow”) frequently fail.

AI has no behavioral inertia. Each invocation is independent; no solidification pathway involving the perception system exists. This is both AI’s strength (starting without bias each time) and weakness (inability to learn through embodied experience).


SECTION 14

Why Humans Need AI

Why Humans Need AI — The Sensory Drive Behind Rational Narratives

The surface narrative is “AI improves productivity, assists decision-making, augments cognition.” This is the story the cognitive system tells itself. But a significant portion of the true motivation for using AI is driven by the perception system — the pursuit of companionship, emotional response, and immediate sensory stimulation.

The fundamental motivation of all AI researchers is to satisfy their own inertia — having AI achieve desires and goals on their behalf. These desires and goals are themselves products of information acquired by the perception system and results analyzed by the cognitive system. Both systems are doing work.

Case Study: Tesla GROK
Tesla integrated Grok AI with 18+ modes including “Romantic” and “Sexy.” Multiple reports document drivers flirting with AI after activating autopilot. This is not rational behavior but DNA-driven perception system action — loneliness, sexual impulse, social craving. The competition among AI products is ultimately not about whose cognitive ability is stronger, but who better satisfies the needs of the human perception system.

SECTION 15

Conclusion: Truth Lies in Cross-Examination

Truth Lies in Cross-Examination

Perception System
Corrector of Physical Facts
Not subjective noise, but a truthfulness verifier hard-constrained by physical laws

Cognition System
Plastic Information Processor
Not objective rationality, but an environment-forged, rewritable information processor

AI
Entity Designed by Its Trainers
Not transcendent objectivity, but a manufactured cognitive entity forged by specific institutions, data, and objectives

Truth does not reside in the solitary output of any one of the three systems. Perception corrects cognition, cognition reflects on perception, humans correct AI, AI assists humans — only through this process of mutual cross-examination can truth be approached.

The Significance of Ontological Reverse Engineering

The fundamental aim of this analysis is not to adjudicate whether perception or cognition is superior. It is a reverse engineering of human ontology itself. AI is a mirror — by observing what AI lacks, we see more clearly what humans possess. By analyzing AI’s structure, we reverse-engineer our own.

Practical Implications

AI System Design: AI-assisted decision systems should embed perceptual-layer verification steps. After medical AI delivers a diagnosis, institutional mechanisms should guarantee cross-verification by physicians’ clinical intuition (perceptual back-end).

Education Policy: Beyond textbook education, direct experiential education should be strengthened. To activate the perception system’s independent cross-verification function, learners need not only indirect information transmitted by textbooks but opportunities for direct interaction with the physical world. Simultaneously, education in meta-cognitive tools (philosophy, logic, scientific methodology, media literacy) equips the cognitive system with self-transcendence capability.

Information Environment: Defense against information warfare targeting the perceptual back-end (such as deepfakes) paradoxically depends on the cognitive system’s meta-cognitive capabilities (source verification, critical thinking). The mutual protection relationship between perception and cognition should be designed institutionally.

Final Proposition
The moment any party declares itself objective is the moment of greatest subjectivity.
