天下本无事，庸人自扰之
Tiānxià běn wúshì, yōngrén zì rǎo zhī Under heaven there is fundamentally no matter; the mediocre man disturbs himself over it The world makes no trouble. Small men manufacture their own.
A clerk in the prefectural office at Puzhou has done something wrong. The record does not say what — it was too small to be worth preserving. The prefect calls him in, tells him not to do it again, and sends him back to work. A senior officer objects: the man should be caned. The office has to be seen to have teeth. Letting it pass teaches everyone the wrong lesson. The prefect asks him whether he seriously imagines the clerk failed to understand plain speech. People’s feelings, he says, are much the same as one another. And if somebody has to be beaten before a point can land, we may as well begin with you.
What it means
天下 — tiānxià, “under heaven” — is not the world in the sense of the planet, or life in general. It is the empire: the whole of what a government holds itself responsible for. The word belongs to administration. Whoever uses it is talking about the management of things.
本, běn, means at root, originally, in its own nature — the state of affairs before anyone got involved.
庸人 is the phrase that resists English. Yōngrén is not a villain and not quite a fool. 庸 is the ordinary, the commonplace, the second-rate: a person of no particular distinction. English has no single word that carries the contempt without also implying stupidity or malice. “Mediocre” is the closest, and the proverb’s claim is that mediocrity is not merely a lack. It is productive. It makes things.
What it makes is 扰, rǎo — disturbance, agitation, harassment, the stirring-up of what was previously still. Bolt 自, “self,” onto the front and you have the modern idiom: 庸人自扰, the mediocre disturbing themselves.
So the sentence makes an unusually strong claim. Not that we tend to overestimate our troubles, which is a claim about calibration, but that the trouble was never out there to begin with. The world was quiet. Someone generated the noise, and the proverb is willing to say what kind of someone.
Where it comes from
The prefect was Lu Xiangxian (陆象先, 665–736), from Wu county near modern Suzhou, son of a chancellor and briefly a chancellor himself in 711. He later governed at Yi Prefecture in Sichuan, then held Puzhou along with the surveillance commission for Hedong. He was known for what the histories call a policy of benevolence and forbearance, and for refusing to establish his authority through beatings — a subordinate who pressed him on it got the reply above. The court gave him the posthumous name Wenzhen.
The saying reaches us through the New Book of Tang, compiled by Song Qi and Ouyang Xiu and presented in 1060 — three centuries after Lu’s death, which is worth stating plainly rather than letting the anecdote pass as transcription. The Old Book of Tang, a century earlier, carries a parallel account.
And what the history actually records is not the proverb. It is this:
天下本无事，庸人扰之为烦耳。第澄其源，何忧不简邪？
Under heaven there is fundamentally no trouble; the mediocre disturb it into vexation. Simply clear it at the source — why fear that things will not stay simple?
庸人扰之: the mediocre disturb it. The world. The thing being agitated is the empire, the office, the situation. The proverb everyone now quotes reads 庸人自扰之 — the mediocre disturb themselves. The difference between the historical sentence and the popular one is a single character, 自.
That character relocated the entire complaint. Lu was not comforting an anxious man; there was no anxious man in the room. He was an administrator addressing a subordinate who had come to ask permission to hit someone, and he was diagnosing an occupational disease — the official who manufactures procedure, infractions and punishments in order to demonstrate that he is officiating. 第澄其源, clear it at the source, is not spiritual counsel. It is management advice.
Somewhere between the New Book of Tang and the modern dictionaries, a reflexive slipped in, and the trouble moved from the office into the skull.
How it gets used today
The idiom is registered as derogatory, and it behaves grammatically as a predicate or an object — you accuse someone of 庸人自扰 rather than merely observing it. The dictionaries gloss its target as the person who invents difficulties for himself, and pair it with 杞人忧天, the man of the state of Qi who lay awake fearing the sky would fall.
The modern usages that the idiom dictionaries carry are instructive about tone. In Mao Dun’s Rainbow, a character brushes off a scandal: the business is long over, the rumour has already been round the entire city, so why manufacture trouble and treat it as a catastrophe. In Hua Ershi’s Han Yiguan, a man stops at a doorway with his back turned and says, almost as a warning, simply not to do this — 不要庸人自扰.
That imperative is the giveaway. The phrase is overwhelmingly something one person says to another, and usually to make them stop. It is not a meditation. It is an interruption.
Cousins from other tongues
Japanese makes the same claim and declines to insult anybody. 案ずるより産むが易し — anzuru yori umu ga yasushi, “than worrying about it, giving birth is easy.” The proverb works by putting the most feared physical ordeal a person could name on the easy side of a comparison, which settles the question without ever raising the worrier’s character. Where the Mandarin hands down a verdict on what sort of person you are, the Japanese produces evidence and lets it stand. Japanese dictionaries note that most modern uses have nothing to do with childbirth at all; the labour has become purely a unit of measurement, the heaviest one available, kept in the sentence to prove how light the dreading was by comparison.
Latin abandons the culprit altogether and goes after the mechanism. Omne ignotum pro magnifico est — “everything unknown is taken for magnificent” — comes from Agricola 30.4, in the speech Tacitus writes for Calgacus as he rallies the Caledonians against Rome. The line is not about private worry but about reputation: Rome is terrifying at a distance, and distance is doing much of the work. The observation is optical rather than moral. Emptiness is what reads as vastness; a blank is magnified because it is blank. No one is being called mediocre, because on this account the effect is a property of ignorance itself, and everybody is subject to it.
Russian keeps the fear and hands it a maker. Не так страшен чёрт, как его малюют — the devil is not as frightening as they paint him. The verb is the whole proverb: малевать is not the dignified word for painting but something closer to daubing, slapping colour about, the work of a bad hand. So the terror turns out to be a picture, and a poorly made one, and — decisively — somebody else made it. The Mandarin worrier is his own problem. The Russian one has been got at.
Why it matters
The proverb has been doing consolation work for a very long time, and it is good at it. Twelve hundred years of people have been told to stop lying awake, on the authority of a Tang official who, in the moment the words were written down, was not talking about lying awake at all.
He was talking to a man holding a stick, who had come to ask permission to use it. The trouble Lu Xiangxian had in mind was not something a person does to himself. It was something one person does to another and files as procedure.
The officer withdrew, ashamed. The cane went back wherever the cane was kept. And the clerk, whose offence was too minor for anyone to trouble to record, walked out of the office and returned to his work, having been told once, and not again, not to do it.
