《人选天选论》 Chapter 1 · The River World

姜蓝著

In my heart there are many ways of seeing the world, which I call “small worlds.” You can think of them as cognitive frameworks. When I first shared my small worlds with Jason, he excitedly told me that this was the underlying logic of nearly eighty percent of AI. Among all my small worlds, the earliest one — the one that most profoundly shaped my life and later work — is the “River World.”

When Wenjie and I were fifteen, we were set on joining the army, eager to serve our country with teenage resolve. The next year, imagining we would take the medical exam, we plotted together and ended up tricking our families out of money, claiming we were going to Wudang Mountain to study martial arts, when in fact we secretly went to Shennongjia. Before we left, we each set a goal for the ten days: I would find the original stone of the He Shi Bi; he would quit smoking for good — he had started at twelve, and after Shennongjia he barely smoked again.

I never found the stone I longed for, but I opened an unexpected door — a door into a small world where I would search for the patterns of reality through independent thought. A quick note: the language I use here is inspired by fantasy novels like Zhe Tian and Jian Lai. It carries no mystical meaning; I oppose all superstition.

My “River World” began with a small river in Shennongjia.

That morning, Wenjie and I each bought a box of Wuhan doupi and ran to the riverbank for breakfast. The water was clear; standing on the bank, you felt you could see straight to the bottom. But when you looked closely, you realized: you could see the bottom, yet you could not see it clearly.

Legend says the He Shi Bi came from Chu, and its original stone was either turquoise or moonstone. The stream flowed; stones stood quietly beneath it. The surface shimmered, light refracted, and shadows twisted, and it flashed with the particular blue glow of moonstone or labradorite. I knew the stone was there, yet I could not see its true face. In that moment, gazing at the stream, I slipped into a strange state of mind. A thought struck me: a person’s mind is like a river. Not merely like — it almost is. Later I mapped the details one by one.

The water in the river is a person’s ever-flowing thoughts. The source is the constant influx of information from outside. The riverbed is one’s nature, experience, and temperament. The stones on the riverbed are the greed and fear hidden deep within. The width of the river is the breadth of knowledge. The depth of the water is the density of knowledge. The speed of the current is the speed of thinking. The riverbanks are the boundaries of what one knows they do not know. The ripples on the surface are excuses, reasons, self-control, and surface emotion.

At first this breakdown may feel abstract, but when you connect it to real people and events, it becomes clear.

Consider the young people who scroll short videos all day and seem worldly: today some finance, tomorrow a slice of history, the day after a bit of emotional wisdom, and then entrepreneurial tips — philosophy, military affairs, technology, everything. At a glance, their cognitive boundary looks wide, like a broad river. The problem is that their water is too shallow. They know a little about everything, but nothing deeply. And when the water is shallow, even a few stones (greed and fear) can stir the surface into chaos: today they swear to charge ahead, tomorrow they collapse midway; today they believe they’ve grasped the meaning of life, tomorrow they’re lost; one moment they want to gallop forward, the next they want to lie flat. It is not that they have no thoughts — rather, they have too many, too scattered, too fast. They have width without depth. The river is wide, shallow, and rushing; the surface can never be calm, full of emotion, self-control, and reasons.

Take an oncology professor by contrast. They may not know every field or follow every topic, yet they can go very deep in one or two directions. Their river is not necessarily wide, but the water is deep. When the water is deep, even with stones at the bottom, the surface is hard to disturb. Such people are stable, less prone to extremes — not because they have no emotion or no greed and fear, but because their water is deep enough.

My friend Chen Changwen has fourteen million followers on Weibo. He reads widely, knows much, and his information breadth is impressive. But a sudden betrayal cost him a huge amount of money and left him disillusioned about human nature. After that, he slowly stopped forming deep ties, and he no longer let chaotic information stream into his heart. He focused on writing and living his own life, as if he had chosen to reduce the flow of his river. He is a special kind of person: his river was wide and not shallow, yet he learned to control his source, to guide his current. That is why his inner world can remain calm — not because the world became quiet, but because he learned to subtract from his thoughts and refuse the flood.

So the “river of thought” differs greatly from person to person:

Some are wide and shallow. Some narrow and deep. Some wide and deep, yet the current is too swift to control. Some rivers were once clear and calm, yet a huge inflow turned them into chaos.

To truly see oneself, the first step is not to ask: What am I greedy for? What am I afraid of? The first step is to ask: what kind of river am I? It sounds simple, but many people never think about it. They stare at the surface: “I’m in a bad mood today,” “I’m anxious today,” “I’m suddenly motivated,” “I suddenly feel like doing nothing.” They assume the problem lies in emotion itself, so they try to control emotion — studying psychology, attending motivational classes, meditating, chasing self‑help. Many struggle for a long time and return to the same point. It’s not that these methods are useless; it’s that they keep circling the surface and never look at the river as a whole.

The surface is always easy to stir: a breeze creates ripples, more water brings flooding, faster flow brings turbulence.

If you only stare at the surface, life feels full of problems and impossible to untangle. But if you step back and look at the whole river from a higher vantage, you will find that many answers were already written into the river’s shape. Some people are anxious not because they are too sensitive, but because their river is too shallow — a small thing touches the bottom. Some people obsessively spiral not because they can’t think clearly, but because their river is too narrow — all problems collide in a tiny channel. Some people swing between passion and pessimism not because they are contradictory, but because their flow is too great — information pours in like a storm, and the river never slows down. Some people have good conditions, yet feel life is chaotic — not because the world targets them, but because their flow is too fast; the water keeps rushing, and nothing has time to settle before the next wave sweeps it away.

Too many people make life too complex, searching for a universal answer, a method to solve everything. In truth, many problems are decided much earlier.

What determines the shape of the surface is never the surface itself, but the form of the whole river. If you do not first see your own river, all effort may be applied in the wrong place.

Some people pour water in, thinking more information will solve everything, only to make the surface more chaotic. Some try to control the speed of the current, yet the river is too shallow; no matter how slow it is, the stones still disturb the surface. Some try to dam a single turbulent patch without realizing the real problem lies beneath.

Over time I formed a habit: when I see someone chaotic and distressed, I do not rush to their emotions; I first ask: what does their “river of thought” look like? Is it too narrow, too shallow, too full, too fast? Once you see that clearly, many problems are already half‑solved. But as I followed this thread, a new question surfaced:

If thought is like water, always in motion, where does it ultimately flow?

Human communication is an exchange of thoughts — one river flowing into another. But if that were all, thought would quickly disperse. Yet many thoughts do not vanish; some last decades, centuries, even millennia. Why? Because humanity has always done one thing: build containers for the river’s water.

The earliest containers were oral stories. Then came words carved on oracle bones and bamboo slips. Later, books. Then paintings, music, film. Today, large language models and AI. The forms differ, but the core is the same: to capture a river’s water so thought can endure.

A book is a river preserved. Decades of observation and reflection vanish if only spoken in casual conversation; but once written, that river is poured into a vessel. Centuries later, someone opens the book, and that river flows again across time into their heart, letting thought continue.

Art is the same. A painting is a fragment of the artist’s thoughts; a piece of music is the flow of their inner waves; a film is a story woven from their understanding of human nature and life. These are all pieces of a river, solidified into form. When later generations approach, the sleeping river begins to flow again.

History, too, is the sediment of countless rivers of thought. History is not merely cold years and events, but the compressed riverbed of people’s thoughts, choices, desires, and fears. To read history is to stand on the bank of time and watch those rivers — how they flowed, converged, and shaped the world.

Humanity advances through history not because each generation starts from zero, but because the rivers of thought of those before us did not disappear. They were stored in vessels, transmitted across time. When we read, we let the water of centuries ago flow into our own river; when we study history, we gaze at dried riverbeds; when we touch art, we touch another river’s former current.

The width of my own understanding and the calm of my inner current did not appear from nothing. I stand on the shoulders of ancient sages and draw from a vast treasury of thought. Some once mocked me and said I wanted to become a “sage.” I never had such a wish. The sages innovated and opened the way; I merely inherit and carry forward. I know I have received a great gift from humanity’s treasury of thought, and thus owe a great debt. That debt is the duty of inheritance — before I leave this world, I have an obligation to pour my own river into a vessel and return it to the world. Even if the vessel adds only a drop to the sea of human thought, even if it pays only one percent of the interest, I consider my life worthwhile. That is why I often joke that I am broke — a lifetime spent repaying this debt. And those who repay have no right to demand understanding, nor to resist criticism and doubt.

So when I later began to write, I asked myself: if I pour my river into a book, will my river one day run dry? Later I realized this is not so. When water enters a vessel, it does not vanish; it only changes form. The water in the book will flow into countless hearts, nourishing their rivers; their rivers will then produce new currents that return to my world.

Thought is never a one‑way current; it is more like a vast watershed — countless rivers exchanging, dividing, merging, polishing each other’s beds, nourishing each other’s flow. Beginning to express oneself is not a depletion of one’s river. On the contrary, it is how a river becomes truly eternal. And as a river begins to flow swiftly, its silt is washed away, its stones are carried forward, and truths once hidden on the riverbed slowly appear. The river grows deeper.

And when the river deepens, you begin to see things you had never seen before — the things buried in the deepest riverbed, rarely seen, yet truly capable of changing the direction of the flow.

That day by the stream in Shennongjia, I had not yet fully understood these truths, but I already sensed one thing: to truly see yourself, it is not enough to watch the flowing water, nor even the whole river. The real forces that determine the river’s direction are always below — on the riverbed.

This is the next story in the River World: “The Stones of Greed and Fear.”
