Gnaeus Marcius — Coriolanus — spent the first half of the fifth century BC saving Rome from calamity, repeatedly, on battlefields far from the city.1
Because he was always away fighting, few Romans knew him personally. Greene's phrasing for what that produced: "making him something of a legendary figure."1
In 454 BC he decided to convert the legend into office and stood for consul.
The first speech went beautifully. He came before the people and displayed the dozens of scars he'd accumulated over seventeen years of fighting for Rome. Greene notes that few in the crowd really heard the lengthy speech that followed — "those scars, proof of his valor and patriotism, moved the people to tears." Election seemed certain.2
By the end of the third speech the crowd had shouted him down, the tribunes had condemned him to death, and when the sentence was commuted to permanent exile the city held a celebration larger than any it had thrown for defeating a foreign enemy.3
Hold on to the detail about the first speech, because it's the whole case in miniature.
Few in the crowd really heard the lengthy speech. The scars did the work. A body covered in seventeen years of evidence makes an argument that cannot be contradicted, cannot be misheard, and — crucially — cannot say anything else.
A scar has one meaning. A speech has as many as there are listeners.
So Coriolanus arrived holding the strongest possible instrument and immediately started using a weaker one alongside it. And the weaker one had a property the scars lacked: it could reveal him.
Speech one — the scars. Tears, near-certain election.
Speech two — polling day. He entered the forum escorted by the entire senate and the city's patricians. The common people watching were "disturbed by such a blustering show of confidence on election day."2
Then he spoke, mostly addressing the wealthy citizens who had come with him. Greene's inventory of what he said: words "arrogant and insolent," a claim of certain victory, boasts about his battlefield exploits, "sour jokes that appealed only to the patricians," angry accusations against his opponents, and speculation about the riches he would bring to Rome.2
This time the people listened. Greene's line: "They had not realized that this legendary soldier was also a common braggart."2
Speech three — the apology that wasn't. After the grain crisis and the riots, the people offered him terms: appear, apologise, agree to keep his opinions to himself, and return to the battlefield.
He appeared. The people "listened to him in rapt silence." He began slowly and softly — and then, as the speech went on, became more and more blunt.
Yet again he hurled insults! His tone was arrogant, his expression disdainful. The more he spoke, the angrier the people became.3
The tribunes condemned him to be thrown from the Tarpeian rock. The patricians got it reduced to lifelong banishment.
The middle of this story is usually skipped, and it's where the damage becomes irreversible.
After losing the election, Coriolanus went back to the battlefield "bitter and vowing revenge on the common folk." Then a large shipment of grain arrived, and the senate prepared to distribute it free to the people.4
He came back specifically to argue against it. And he won — "several senators appeared won over, and the vote on the distribution fell into doubt."4
Then he kept going. He condemned the concept of democracy itself, and advocated abolishing the tribunes and handing the city to the patricians.4
Two separate things happen there and they're worth keeping apart.
The grain argument was a policy position, and he was persuasive enough to nearly carry it. Whatever you think of it, that's a politician functioning.
The attack on the tribunes was a disclosure. It told the people not what he wanted for the grain but what he wanted for them, permanently. And once stated, it could not be un-stated — the riots that followed were about that, not the grain, which the senate hastily approved anyway.
So the sequence is: he loses an election by revealing his manner, then loses the city by revealing his programme. Greene's law is about volume, but the case is about irreversibility. Each speech converted a private disposition into a public fact, and public facts accumulate.
Before his entrance into politics, the name of Coriolanus evoked awe… Since the citizens knew little about him, all kinds of legends became attached to his name. The moment he appeared before the Roman citizens, however, and spoke his mind, all that grandeur and mystery vanished.5
The mechanism, stated:
The discrepancy between the legend and the reality proved immensely disappointing to those who wanted to believe in their hero.5
Note wanted to believe. The Romans were not neutral assessors who received new data and updated. They had an investment in the legend, and Coriolanus's speeches forced them to give it up — which is a loss, and losses produce anger rather than reassessment.
Then Greene's compression of the whole law:
The more Coriolanus said, the less powerful he appeared—a person who cannot control his words shows that he cannot control himself, and is unworthy of respect.5
Worth being precise, because it explains why the collapse was total rather than partial.
The legend was not built by Coriolanus. It was built by Romans, in his absence, out of very little — scars, victories, and the fact that nobody had met him. Greene: "all kinds of legends became attached to his name."
Which means it was their construction, and it was better than any real man could be, because it had no specifics in it to disappoint anyone.
He didn't damage a reputation he owned. He repossessed a story other people had been writing and replaced it with himself, and the replacement was necessarily smaller.
That's the same structure as the Marquis de Sevigné destroying six weeks of Ninon's campaign with one word — and Greene builds it as a law about talking too much, which is the surface of it rather than the mechanism.
You've been brought in to lead something on the strength of a reputation, and the first all-hands is next week.
The instinct is to introduce yourself properly — say who you are, what you believe, how you work. That instinct is Coriolanus walking into the forum with the senate behind him.
Before it, work out what people currently believe about you and where the belief came from. If it came from results they heard about rather than time they spent with you, you are holding a legend, and legends have one property: they are better than you and they are not yours.
So the rule for that meeting is not brevity for its own sake. It's: say only what you would be willing to have quoted back to you in two years. Everything else waits until it's demonstrated.
And watch the second speech specifically — the one you give when you've already won. Coriolanus lost the election with a speech delivered on the assumption that the election was won, to an audience he had stopped needing. That is the reliable moment: not the pitch, but the remarks afterwards, when the guard drops and the real register comes out.
If you're going to be arrogant somewhere, be arrogant before the vote, when people are still checking. After the vote they're not assessing you any more — they're forming a settled view.
Strongest support. A three-stage sequence with escalating consequences, each stage traceable to a specific speech, ending in an outcome so unambiguous (a celebration larger than one for a military victory) that the causal claim is hard to dispute.
Tension — the law and the case disagree about the failure. Law 4 is Always Say Less Than Necessary, and Greene's interpretation is about volume: "the more Coriolanus said, the less powerful he appeared." But the second speech's content is what did the damage — arrogance, patrician jokes, contempt. A shorter speech containing the same contempt would have failed identically. The case supports "do not reveal what you actually think of people", which is a different law.
Tension — silence would not have solved the grain problem. Greene's counterfactual is that "had Coriolanus said less, the people would never have had cause to be offended… He would have maintained his powerful aura, would certainly have been elected consul, and would have been able to accomplish his antidemocratic goals."6 That last clause assumes a consul can abolish the tribunes without ever stating the intention. Greene endorses a programme here in passing, and the endorsement is worth marking.

Open questions.
Greene's Discreet Versus Overt Flattery — built at Law 1 in this cluster — teaches that a request for help beats a compliment, because praise is a transaction the room can score and a question isn't.
Coriolanus is the same insight in the negative and at scale.
The second speech was not merely arrogant; it was arrogance the room could score. Sour jokes that landed only with the patricians told everyone present exactly where the speaker's allegiance sat, and did it more reliably than any declaration would have.
The pair yields something neither states: the audience's real information comes from who your remarks are calibrated for, not from their content. Coriolanus never said I hold the common people in contempt. He made jokes that only the wealthy could enjoy, in front of the poor, and that was sufficient. Which is why the counsel of Law 4 is weaker than the case underneath it — brevity does not help if the little you say is still aimed at the wrong half of the room.
→ behavioral-mechanics · Ninon de Lenclos and the Marquis
The Law 3 case: a six-week campaign destroyed by one word, because revealing an intention retroactively recolours everything already done and takes the story away from someone who was enjoying writing it.
Coriolanus is the identical mechanism in public rather than private, and putting them together shows the law Greene has split across two chapters.
The countess had been authoring a version of the marquis. The Romans had been authoring a version of Coriolanus — "all kinds of legends became attached to his name." In both cases the construction was flattering, self-generated, and better than the real person, precisely because it contained no specifics.
And in both cases the subject repossessed it. The marquis with love; Coriolanus with a speech about his own exploits.
The insight neither page reaches alone: absence is not a neutral state, it is a production process. The people who don't know you are not waiting for information — they are manufacturing a version, and the version is working for you. Which reframes Law 4 entirely. Say less is not primarily about avoiding mistakes or seeming powerful. It is about not interrupting the manufacture, and the reason both cases collapse instantly rather than gradually is that a construction cannot be partly repossessed.
→ psychology · Emotional Mastery as Power Foundation
The Preface page records Greene's actual position: feel the emotion fully, express it with care, never let it hold the pen.
Corialanus is the failure of the third clause specifically, and the case is precise about which emotion.
He returned to Rome for the grain vote "bitter and vowing revenge on the common folk who had voted against him."4 The bitterness didn't merely colour his speech — it selected the occasion. He came back to Rome to speak on a food distribution because he was angry at the people who would eat it.
So the failure is upstream of anything he said. By the time he was on the senate floor the ruinous decision had already been taken, which was the decision to engage at all.
The insight neither page yields alone: the emotional damage in a power situation is usually done at the moment of choosing which room to enter, not at the moment of speaking in it. Law 4's advice operates entirely inside the room and therefore arrives too late for the case it's built on. Coriolanus with perfect verbal discipline and the same bitterness still travels to Rome, still opposes the grain, and still ends up on the Tarpeian rock — just more slowly.
Sharpest implication. The legend was never his. Romans built it in his absence out of scars and rumour, and it was better than any real man could be because it had no specifics in it to disappoint anyone. What he lost in the forum was not a reputation he had earned but a construction other people were maintaining for free — and the moment he supplied specifics, the maintenance stopped and the whole thing was his to hold up alone.
Generative questions.
