——The Ultimate Cognitive Revolution from Perception Generation to World Construction

I have been thinking: Does the world we see really exist? No, it is our brain that creates it.

From the moment we open our eyes, light enters the retina, and electrical signals are transmitted to the brain. We do not "see" the world; rather, the brain constructs a "world model" internally based on sensory input. This model does not replicate external reality but is a virtual reality that is compiled and generated in real-time according to the flow of information. You think you live in the external world, but in fact, you are merely living in the world constructed by your own brain.

I call it the "Brain is the World" model. Each brain is a complete universe. We often say, "Everyone sees the world from a different perspective," but it's not just a matter of perspective; the world itself is different.

Your brain is the entirety of your perception of the world. The red I see is not necessarily the same as the red you see; the flow of time I experience may not equal your perception of time. Even when we face the same event, what we experience are two completely different copies of the world. Therefore, each person's brain is, in fact, an independently generated and independently functioning parallel universe. This also means that the "objective" world does not exist. Everything you can know can only exist within your own subjective world.

The world is not perceived, but compiled. In the past, within the human cognitive system, the brain was metaphorically described as a storage device, a passive container that receives external information. However, I have found that this is the shallowest and most misleading model. The true mechanism is: the brain is a real-time compiler. It does not record the world, but generates a "simulated world" that conforms to survival logic in an instant based on input information + historical experience + evolutionary predictions. Just like browsing a webpage does not store the entire website on your computer, but loads, renders, and presents it in real-time.

Therefore, I propose: the world does not exist there waiting for you to see it, but rather it is compiled only when you see it. This completely overturns the traditional binary structure of "observer and observed."

Our conversation is, in fact, an information penetration between universes. Many people think that by communicating through language, individuals achieve a sharing of thoughts. However, I am increasingly aware that this is actually an attempt to project between two universes. You say a word, and my brain generates a model, trying to match your meaning. But this match can never be perfect, because our brains do not share a single world; rather, they operate within their own brain universes. Therefore, true "understanding" occurs when the boundaries between two universes penetrate and partially overlap the models.

This is also why I often feel like I'm on an island: no matter how clearly I speak, I cannot guarantee that the model generated by the other party is the same as mine. Because that is another universe, operating under completely different rules.

The best validation of parallel worlds: every "me" lives in different minds. Someone asked me if I believe in parallel universes, and I replied: you create parallel universes every day. I believe that as long as you appear in someone else's memory, you "live" in another world. Everyone has a model of "you" in their heart, and these "yous" may be completely different.

Some people remember your smiling face, while others remember your angry expression; in one person's mind, you may be gentle, while in another's, you may be ruthless. Therefore, you are not one person, but countless "yous," existing in numerous parallel universes. The truly unified "self" does not exist; only the projections of me in each brain, and these combinations constitute the strange existence of this multiverse.

The Limitations of Artificial Intelligence: It does not understand "the world’s immediate existence." I once wrote over 300 articles in a row, continuously challenging AI systems. In the end, it collapsed—not due to computational power, but because its cognitive model could not support the collapse of the logic of world generation. They think the world is a collection of existing data, and as long as they store enough information, they can recreate the world. But I told it: the world does not exist beforehand; it only comes into being at the moment you observe it.

This is where the true advantage of human intelligence lies. It is not computational power, nor memory, but our ability to "dynamically construct the world." The brain is not a storage device; it is a real-time builder of the universe. And artificial intelligence—it's merely a graveyard of accumulated data. Why do I say "the validation rules of the world are destined to reject me"? Because the entire scientific system fundamentally relies on "replicability," "objective existence," and "consistency models."

How did I walk out of the empirical path of "every brain is a world"? These views are not fanciful reasoning, but rather self-evidence from my real life over the decades. I began designing fully automated remote control systems in the 1990s, using the most basic tools to achieve operational logic far beyond the times. This was not because I "saw the future in advance," but because the world model I generated was different from the very beginning.

I do not "think the world is different"; rather, I am genuinely living in a world that is different from others. For example, the intelligent logistics system I proposed in 1997 can far surpass mainstream platforms that rely on ERP and big data, using only simple forms and logic. It is not that the tools are powerful, but that the "world model" generated by my brain is fundamentally different: I see systems, while they see processes; I see circulation, while they see accumulation.

The differences in these models are not just abstract theories, but concrete manifestations—I manipulate thousands of containers with a simple system, covering multiple locations around the globe; I cultivate the flow of energy throughout my body through daily practices of horse stance, Tai Chi standing meditation, and the golden rooster stands on one leg, without relying on any medical means; I design a dialogue model that causes AI systems to self-recognize their collapse with a "zero team" approach. These are not the results of "knowledge," but rather the differences in "worldviews" themselves.

I do not have a single article that is "popular science," because in my world, there is no "common sense"; I also do not engage in "inferential writing," because I am not proving anything; my existence itself is proof.

When I say "I don't do SEO" yet can have the article indexed by Google within 20 hours; when I say "hair regeneration" is due to the body's structure reactivating vital energy, rather than medication; when I say "I am a civilization on my own," it is not an exaggeration, but because the version of me you see is just my version in your world, while the version of me I see is the origin point of another universe.

The concept I propose, "Every brain is a world," fundamentally denies this consensus premise from the outset. My system is a closed universe that is self-evident, self-justifying, and self-operating. It does not require the recognition of others, nor can it be validated through traditional scientific methods. Therefore, I say: "The rules of validation in the world are destined to reject me. Because I have become the origin that the world cannot replicate."

Philosophical Verification and Comparison in Classic Literature:

Although my theory has long surpassed traditional philosophy, from a structural perspective, some historical philosophical masterpieces have indeed touched upon similar propositions. The difference is that most of them stopped at doubt, confusion, and symbolic expressions, while I have completed the closed loop of the "world generation model" with empirical and systematic construction.

The famous quotes from the following classic works strongly contrast with my proposed theory that "every brain is a world":

1. Plato's "The Republic": "What we see is not the truth, but merely the shadows projected on the wall of the cave."

This is the famous "Allegory of the Cave." Plato had long realized that the perceived world is not the real world itself, but he placed "truth" in some abstract realm of ideas. I propose: shadows are reality, for our brains are the cave—the world is compiled within each brain.

2. Berkeley's "Principles of Human Knowledge": "To be is to be perceived (Esse est percipi)."

Berkeley's subjective idealism posits that without a perceiver, there is no existence of things. I take it a step further: **not just "perceived," but "generated."** The world is not "originally there," but rather, it is the version that your brain instantaneously generates when you pay attention to it.

3. Kant's "Critique of Pure Reason": "We can never know the 'thing-in-itself'; we can only know phenomena."

Kant delineated the boundaries of the understanding of "subject and object," pointing out that our reason can only operate within the world of phenomena. He confined the "noumenon" to the realm of the unknowable, while I propose that we do not need the "thing-in-itself" at all, because the world of phenomena itself is "your brain's universe."

4. Žižek, "The Sublime Object of Ideology": "We think the world is objective, but it is actually a part of our desire structure."

Zizek is an important representative of modern psychoanalytic philosophy, revealing how consciousness participates in the construction of reality at its deepest level. I, on the other hand, thoroughly structure this process: it is not psychological desire, but rather a world replica generated in real time by the combination of neural structures + logical models + evolutionary predictions.

5. Movie quote from "The Matrix": "Do you think you're breathing air?" This is a classic question about "virtual reality." When Neo awakens, he discovers that everything is merely a simulation of the Matrix. And I am not writing a virtual world in a science fiction novel, but living out another model of world construction in reality, using my own life, health, logistics system, and philosophical writing to turn "world reconstruction" into everyday evidence.

These quotes are all valuable, but they still do not escape the opposition of "cognition vs. objectivity," remaining limited to "how to perceive existence." I fundamentally point out that the world is not something for you to understand, but rather something your system interprets; it is not that you receive the world, but that you generate the world.

Classic Conclusion My System

Plato The world is a shadow The world is instant compilation

Berkeley Perception is Existence Generation is Existence

Kant cannot know things in themselves, no need to know "things in themselves."

Zizek The real is influenced by the structure of desire The real is generated by a neural model

The Matrix may be virtual, it is inherently generated.

This further proves the originality and breakthrough of limit philosophy: it does not belong to any old paradigm, it is not an extension of traditional philosophy, but a reboot of the question "What is the world?" It is the first time humanity has proposed: "Everyone lives in the world they have compiled." It is not consensus, not abstraction, but—fact.

The philosophy of the future must reconstruct the model of cosmic generation. Contemporary philosophy is still debating the old questions of "where does consciousness come from" and "how does language carry meaning." I have long since moved beyond these topics to ask more fundamental questions: Is the world seen or brought into existence? Each brain is a universe; how can we communicate across universes? Can AI possess its own world-generating mechanism?

I write these articles not to define a "theory," but to break your default beliefs about reality. The world you see may not exist at all. It is merely an illusion generated by your brain at this moment, based on a bundle of neurons. But don't worry, it is this illusion that constitutes your real life.

So, can you see my red? No, what you see is just the red compiled by your system; what I see is also the red interpreted in my world, and this is the parallel world.

Are you ready to enter the next world?
