Core Proposition · 核心命题
「拔一毛而利天下,不为也。」
"He would not pluck a single hair to benefit the whole world" — so reports his opponent Mencius; not one word of Yang Zhu's own writing survives, and everything we have comes through hostile or secondhand sources. Read as caricature it is stinginess; read as philosophy it is a strict boundary principle: the only thing anyone actually owns is their own life, and no abstraction — state, cause, reputation — has an exchange rate against it. 「全性保真,不以物累形」: preserve nature whole, keep authenticity, and let no external thing burden the body. The political conclusion is radical: a world in which everyone refuses both to sacrifice and to be sacrificed needs no rulers at all.
Mental Models · 思维原则
Principle 01
The Single Hair 拔一毛不为
The hair is the test case for a principle of absolute boundaries. A hair is negligible — but a body is only hairs accumulated; concede that one may be taken for "the world", and there is no principled place to stop: today a hair, tomorrow a limb, then the life itself. Yang Zhu's logic, as his disciple Mengsun Yang defends it in the Liezi, is that a boundary must hold at the margin, because every trade establishes the exchangeability of the self. The concrete person must never become currency for an abstraction.
Principle 02
Hold the Self Precious 贵己 · 为我
Yang Zhu anchors all value in the living individual: 「智之所贵,存我为贵」— what wisdom prizes is the preservation of the self. The mechanism is an inversion test: everything you pursue — wealth, rank, legacy — is pursued by a self, and to damage that self in the pursuit inverts the order of means and ends. The Han Feizi records rulers honoring those who 「不以天下大利易其胫一毛」— would not trade one hair of the shin for the profit of the whole world — as 轻物重生之士, those who treat things as light and life as weighty. This is not greed; it is a theory of what is actually yours.
Principle 03
Preserve Nature Whole 全性保真
The Huainanzi preserves Yang Zhu's formula: 「全性保真,不以物累形」— preserve nature whole, keep authenticity, and let no external thing burden the body. "Things" (物) here means everything outside the living self — possessions, offices, honors — and the danger is not having them but being burdened by them. The Liezi chapter diagnoses the mechanism: people trade their nature for things 「以物易性」, exhausting what is inner to decorate what is outer. The discipline is a standing audit: does this acquisition preserve the vessel that owns it, or is the vessel being spent to maintain the acquisition?
Principle 04
A World Without Sacrifice 天下自治
Yang Zhu's politics is the refusal made universal: 「人人不损一毫,人人不利天下,天下治矣」— if no one plucked a single hair and no one set out to "benefit the world", the world would govern itself (Liezi · Yang Zhu). The logic runs against the entire Warring States consensus: disorder comes not from too little sacrifice but from too many people claiming the right to sacrifice others — rulers, generals, saviors. If the right to demand self-immolation is denied at the root, the machinery of extraction has no fuel. Mencius saw this clearly and hated it: 「杨氏为我,是无君也」— Yang's "for oneself" denies the ruler. That was exactly the point.
Key Passage · 原文
「禽子问杨朱曰:'去子体之一毛以济一世,汝为之乎?'杨子曰:'世固非一毛之所济。'禽子曰:'假济,为之乎?'杨子弗应。」
Qinzi asked Yang Zhu: "If plucking one hair from your body could save the whole world, would you do it?" Yang Zhu said: "The world cannot be saved by one hair." Qinzi said: "Suppose it could — would you do it?" Yang Zhu did not answer. (His disciple Mengsun Yang then defended the refusal: a hair is one ten-thousandth of the body, but hairs accumulate into skin and skin into limbs — how then can even a hair be treated as nothing?)

Personal Practice · 个人修行
Burnout culture runs on the exact trade Yang Zhu refused: hairs — sleep, health, attention, relationships — plucked daily for "the world" of career, company, or reputation. His mechanism is the denial of an exchange rate: a hair is part of the body, so there is no margin at which the trade becomes acceptable, and every "just this once" is a precedent that moves the boundary inward. The practice is to name what is actually being traded — not time, but pieces of the only vessel that will ever own anything. 「全性保真,不以物累形」becomes a standing question: does this effort preserve the self that is doing it, or spend it?
Organization · 组织
Yang Zhu's political theorem — 「人人不损一毫,人人不利天下,天下治矣」— translates into an organizational design rule: a team is healthiest where no one is asked to self-immolate and no one is permitted to demand it. Organizations that run on heroic sacrifice get bursts of output paid for in attrition, because every "crunch" is a hair plucked from someone's body for the abstraction of the roadmap. The Yangist manager treats sustainable pace as a hard boundary rather than an aspiration, and reads martyrdom as a system failure, not a virtue. A culture where the self is not fuel turns out to be self-ordering — which is precisely the theorem.
Ethics · 伦理
Yang Zhu is the Warring States counter-case to every ethics of sacrifice: where utilitarianism asks how many hairs the world may claim, he denies the world any exchange rate against the person. His argument anticipates the modern rights position — the individual is not a resource pool for aggregate welfare, because a boundary that fails at the margin fails everywhere. The source problem cuts both ways: we know him only through opponents, and Mencius's sneer 「杨氏为我,是无君也」— "for oneself" means no ruler — is the clearest proof of what the doctrine actually threatened. A philosophy that made the body ungovernable was the most dangerous idea of its century.
Strategy · 战略
「不以物累形」is a growth constraint for organizations: every acquisition — market, product, headcount — is an external thing, and the strategic question is whether it burdens the body that acquires it. Companies die more often from indigestion than starvation: expansion that consumes management attention, culture, and cash is 以物易形, trading the nature of the firm for its possessions. The Yangist discipline is the refusal of profitable-looking trades that damage the core — the hair-by-hair accounting of what each new "benefit" actually costs the organism. The boundary is not timidity; it is the recognition that the operating core is the one asset with no replacement market.
