Here is a thought experiment from an ancient Chinese text that will make you slightly uncomfortable, and then, perhaps, a little wiser.
A carpenter who builds carriages hopes that people will become wealthy. A carpenter who builds coffins hopes that people will die early. Is the carriage-maker kind and the coffin-maker cruel? Not at all. If people are not wealthy, no one buys carriages. If people do not die, no one buys coffins. The carriage-maker does not love you; the coffin-maker does not hate you. Their wishes are shaped by where their livelihood comes from.
故舆人成舆，则欲人之富贵；匠人成棺，则欲人之夭死也。非舆人仁而匠人贼也，人不贵，则舆不售；人不死，则棺不买。
This is from the Han Feizi, Chapter 17 – Internal Threats (Bei Nei), a foundational text of Chinese Legalist philosophy written in the third century BCE. Han Fei, the thinker behind it, was not a moralist. He was something closer to a cold-eyed analyst of human incentives – a ancient precursor to what modern economists would call homo economicus.
His argument is not that people are evil. It is that people are structurally aligned with their interests, and if you want to understand why someone is pushing you toward a particular decision, you should first ask: What does this person’s livelihood depend on?
Han Fei’s Method: Read the Behavior, Infer the Interest
Han Fei’s advice is deceptively simple: observe what a person does, trace it back to what they need, and you will understand their motives better than any declaration of good intentions.
This is not cynicism. It is a discipline of attention. Most of us default to a moral reading of other people’s behavior: He is being kind. She is being generous. They are being helpful. Han Fei suggests a different reading: What is the structural position from which this kindness, generosity, or helpfulness is being offered?
A matchmaker will enthusiastically encourage you to get married. A micro-entrepreneur selling skincare products will passionately urge you to join their downline. This is not because matchmakers are saints and micro-entrepreneurs are sinners. It is because their interests are embedded in the outcome they are recommending to you.
Once you see this, you do not need to become suspicious of everyone. You simply need to become literate in interests.
The Cold Truth of Human Relationships from Han Fei
Do you think he is merely telling a story about two craftsmen? No. He is talking about every relationship around you and me.
Han Fei, with these two brief sentences, shreds the fig leaf of the claim that “human nature is inherently good”. A colleague treats you well not necessarily out of genuine fondness; it may be that you can bring value to them. A friend lends you a hand not necessarily from innate kindness; it may be that you can repay them someday.
Han Fei is not teaching you to turn wicked. He is forcing you to open your eyes – stop imposing your own moral standards on others, and stop binding yourself to other people’s moral promises. This splash of cold water, cast twenty-three hundred years ago, still jolts people sharply today.
A Striking Parallel: Adam Smith’s Butcher and Brewer
Western readers may find this framework familiar. In The Wealth of Nations, Adam Smith famously wrote:
It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest.
Smith and Han Fei lived more than two thousand years apart, in radically different societies. Yet they arrived at the same structural insight: reliable social cooperation does not depend on people being good. It depends on their interests being aligned with the outcome you need.
The difference is that Smith saw self-interest as the engine of a market economy – a force that, properly channeled, produces general prosperity. Han Fei saw it as a permanent security problem. For him, the question was never “How do we make people virtuous?” It was “How do we design systems so that self-interested people do not destroy us?”
That is a darker question, but it is not an irrational one. Anyone who has been burned by a trusted friend’s business proposal, or manipulated by a colleague’s sudden warmth, knows the cost of assuming that good intentions are enough.
The Hard Sentence: “Trusting Others Means Being Controlled by Them”
Near the beginning of the Bei Nei chapter, Han Fei delivers a line that sounds almost paranoid to modern ears:
人主之患在于信人，信人，则制于人。
The ruler’s calamity lies in trusting others. Trust others, and you will be controlled by them.
In its original context, this is advice for a ruler surrounded by ministers, concubines, and heirs whose interests may not align with his survival. Han Fei’s point is not that every minister is plotting murder. It is that the structure of power creates incentives that good intentions cannot reliably override.
Han Fei’s insight is not confined to palaces and court intrigue. It shows up in the most ordinary moments of modern life.
Translated into ordinary life, the sentence becomes less dramatic but no less useful: do not organize your decisions around the assumption that other people will prioritize your interests over their own. They may. Sometimes they genuinely will. But you should not build your safety, your finances, or your boundaries on that assumption alone.
This is not a counsel of despair. It is a counsel of realism without resentment.
What Han Fei Is Not Saying
It would be easy to turn Han Fei into a prophet of universal suspicion. That would be a mistake.
He is not saying: Everyone is out to get you. He is saying: Everyone is situated somewhere, and situations shape behavior.
He is not saying: Kindness is fake. He is saying: Kindness that costs the kind person nothing is easy; kindness that runs against the kind person’s interests is rarer, and therefore more meaningful.
He is not saying: Never trust anyone. He is saying: Trust should be calibrated to structural reality, not to the warmth of a smile or the length of a friendship.
The practical translation is simple: stop sorting people into “good” and “bad,” and start noticing where their livelihood, their loyalties, and their calculations actually lie. Once you see the structure, you can protect yourself without hatred, and cooperate with others without illusion.
