Core Debates Across the Hundred Schools · 核心议题辩论

These are the fault lines where the schools disagreed. Each debate frames a single question and sets the opposing answers side by side — one sentence per position, with the original words where they survive.

The Five Debates · 五大论战
Debate 01 Human Nature 人性之辩
QIs human nature good or self-interested?
性善 Nature is Good
Mencius 孟子
Every person is born with the four sprouts 四端 — compassion, shame, deference, and a sense of right and wrong — and virtue is cultivated from within by nurturing them.
「仁义礼智，非由外铄我也，我固有之也。」 Benevolence, righteousness, ritual, and wisdom are not welded onto me from outside — they are inherently mine.
性恶 Nature is Self-Interested
Xunzi 荀子
Human nature is self-interested and prone to disorder; goodness is deliberate artifice 伪 — ritual, law, and teaching straighten the crooked wood into something useful.
「人之性恶，其善者伪也。」 Human nature is self-interested; its goodness is deliberate artifice.
VS
Aside · Gaozi 告子 held a third view — nature is morally neutral 性无善无不善, like water that flows whichever way it is channelled.
Debate 02 Virtue vs Law 德治与法治
QShould order come from moral example or from impersonal law?
德治 Rule by Virtue
Confucius 孔子 Mencius 孟子
Order flows from the moral example of the ruler — lead the people by virtue and align them with ritual, and they will develop a sense of shame and correct themselves.
「道之以德，齐之以礼，有耻且格。」 Lead them by virtue, align them by ritual — they will have a sense of shame and order themselves.
法治 Rule by Law
Shang Yang 商鞅 Han Feizi 韩非
Order comes from impartial, public law — clear rewards and punishments that harness self-interest, applied without regard to rank or moral character.
「法者，国之权衡也。」 Law is the scale and plumb-line of the state.
VS
Debate 03 Righteousness vs Profit 义利之辨
QIs profit a legitimate aim or the root of disorder?
重义轻利 Righteousness First
Mencius 孟子 Confucius 孔子
Profit-talk sets people against one another and is the root of disorder — the gentleman understands duty 义, the petty person understands profit 利.
「何必曰利？亦有仁义而已矣。」 Why must you speak of profit? There is only benevolence and righteousness. — and 「君子喻于义，小人喻于利」
义利统一/尚利 Benefit as Standard
Mozi 墨子
Benefit to all people is the test of rightness — the three gauges 三表法 judge any doctrine by whether it actually benefits the populace; the Legalists go further, treating profit and interest as the very levers of rule.
「仁人之事者，必务求兴天下之利，除天下之害。」 The benevolent person must surely seek to promote the benefit of the world and eliminate its harm.
VS
Debate 04 Engagement vs Withdrawal 出世与入世
QShould the worthy serve the state or preserve themselves?
入世 Engage
Confucius 孔子
The worthy have a duty to serve the world even when success is unlikely — retreat into purity abandons the people, and effort is owed regardless of outcome.
「知其不可而为之。」 Do it, knowing it may fail — a contemporary's description of Confucius himself.
出世 Withdraw
Laozi 老子 Zhuangzi 庄子 Yang Zhu 杨朱
Service to a corrupt state destroys the self — the Taoists answer with 无为 wu wei and the useless tree that survives because no axe wants it; Yang Zhu answers 全性保真, preserve the self and hold fast to one's authenticity, not trading a hair of one's body for the empire.
「人皆知有用之用，而莫知无用之用也。」 Everyone knows the use of the useful; no one knows the use of the useless.
VS
Debate 05 Views on War 战争观
QWhen, if ever, is war justified?
非攻 Condemn Aggression
Mozi 墨子
Offensive war is the greatest crime — theft and murder scaled up to the size of states — but defensive war is permitted and must be skillfully mounted.
义兵 Just War
Mencius 孟子 Xunzi 荀子
A punitive war to rescue a suffering people can be righteous — executing a lone tyrant is justice, not regicide; Xunzi's 义兵 restores order rather than seizing land.
「闻诛一夫纣矣，未闻弑君也。」 I have heard of executing the lone tyrant Zhou — I have not heard of regicide.
慎战/兼并 Strategic War
Sun Tzu 孙武
War is a grave matter of the state and a last resort — victory is designed before battle is joined; the Legalists treat war as an instrument of unification.
「不战而屈人之兵，善之善者也。」 Subdue the enemy's forces without fighting — that is the acme of skill.
