The obvious career move is to get close to whoever has the most power. Find the strongest patron, the best-run department, the boss who is going places, and attach.
Greene says this is a mistake, and the reason is one sentence long:
No one will come to depend on you if they are already strong.1
That is the whole argument, and it is worth sitting with because it inverts an instinct almost everybody has.
A strong master does not need you. Whatever you supply, they have alternatives — that is largely what being strong consists of. So the attachment is one-directional: you need them, they tolerate you, and the arrangement lasts exactly as long as it suits them.
Joining forces with the powerful can be foolish: They will swallow you up, just as the doge of Venice swallowed up the Count of Carmagnola.1
So the recommendation:
If you are ambitious, it is much wiser to seek out weak rulers or masters with whom you can create a relationship of dependency. You become their strength, their intelligence, their spine. What power you hold! If they got rid of you the whole edifice would collapse.1
Their strength, their intelligence, their spine. Three things a weak ruler lacks, and each one is a position that cannot be filled by anybody else once you are in it.
The chapter's judgment states the operating rule even more baldly: "Never teach them enough so that they can do without you."2
That clause is the law's honest centre, and it is where the strategy stops being merely clever. Everything else here could describe becoming genuinely useful. That sentence describes withholding — deliberately maintaining someone else's incapacity because their incapacity is your position.
Underneath the tactic is a claim about what actually moves people:
Necessity rules the world. People rarely act unless compelled to. If you create no need for yourself, then you will be done away with at first opportunity.3
This is bleak and it is not obviously wrong. Greene's point is that being valued, liked, or acknowledged as excellent are all sentiments, and sentiments do not survive a budget cut. Being needed is a structural fact, and structural facts do.
And it explains the condottieri who open the chapter. They won battle after battle and were banished, imprisoned or executed — not because anyone was ungrateful, but because there were many other condottieri as able as they were. They were replaceable, and nothing was lost by killing them.
Gratitude is not the variable. Substitutability is.
Greene's case is precise and worth following, because it is not a story about loyalty.
In 1847 Bismarck was thirty-two, a new deputy in the Prussian parliament, "without an ally or friend." He looked at the available options — the liberals, the conservatives, any particular minister, the people — and chose the king.4
Frederick William IV was, in Greene's description, "at a low point of his power. A weak, indecisive man, he consistently gave in to the liberals in parliament; in fact he was spineless, and stood for much that Bismarck disliked, personally and politically."4
So Bismarck selected a patron he disagreed with, whose politics he disliked, and whose defining feature was weakness. And he "courted Frederick night and day. When other deputies attacked the king for his many inept moves, only Bismarck stood by him."4
Only Bismarck. That is the position being purchased — sole supplier.
By 1851 he was a minister. Then he went to work: forcing the king's hand, building the military, standing up to the liberals, working on "Frederick's insecurity about his manliness, challenging him to be firm."5 And here is the part that makes the strategy remarkable — he restored the king's powers until the monarchy was once again the most powerful force in Prussia.5
He made his weak master strong, having first made himself the mechanism by which that happened.
The strategy's real proof is what happened when Frederick died in 1861.
His brother William took the throne, "disliked Bismarck intensely and had no intention of keeping him around."6
On any ordinary account of patronage, that ends the career. The patron is dead and the successor is hostile.
It did not, and the reason is structural rather than personal: William "inherited the same situation his brother had: enemies galore." He actually considered abdicating, feeling he lacked the strength for it.6
Bismarck "insinuated himself once again." The king "grew dependent on Bismarck's strong-arm tactics to keep his enemies at bay, and despite his antipathy toward the man, he soon made him his prime minister."6
Then the mechanism in its purest form: "Whenever the prime minister threatened to resign, the king gave in to him, time after time."6
The dependency survived the transfer of the throne and the active dislike of the man on it. Bismarck was not attached to Frederick; he was attached to a position — the person who handles the enemies — and the position outlasted its occupant.
Greene draws out the quality that separates this from ordinary leverage:
The ultimate power is the power to get people to do as you wish. When you can do this without having to force people or hurt them, when they willingly grant you what you desire, then your power is untouchable.7
And the demonstration: "Bismarck did not have to bully either Frederick or William into doing his bidding. He simply made it clear that unless he got what he wanted he would walk away, leaving the king to twist in the wind."7
No threat is issued. Nothing is done to anyone. The entire pressure comes from the credible possibility of absence, which costs nothing to maintain and cannot be resented, because withdrawing your own labour is not an attack.
It is the same shape as Brunelleschi's illness at Law 8, run permanently instead of once.
Then the chapter's genuine philosophical claim, and the one most worth arguing with:
Do not be one of the many who mistakenly believe that the ultimate form of power is independence. Power involves a relationship between people… The completely independent man would live in a cabin in the woods—he would have the freedom to come and go as he pleased, but he would have no power. The best you can hope for is that others will grow so dependent on you that you enjoy a kind of reverse independence: Their need for you frees you.8
Their need for you frees you.
That is a real reframing. Independence as ordinarily imagined — needing nobody — is here recast as irrelevance with good scenery, and freedom is relocated into the structure of other people's requirements.
It is also, on inspection, a trade rather than a solution. Reverse independence requires you to remain permanently available to the person depending on you. The man in the cabin can leave. Bismarck could not — the whole edifice would collapse, which is precisely what made him safe.
Greene names the freedom and does not price the tether, and the chapter's own margin does: Kipling's cat keeps a bounded contract and walks by himself, which is a third option the chapter's binary has no room for.
You are choosing where to attach yourself.
First, ask what the prospective master cannot do. Not what they need done — what they are unable to do. Bismarck's read on Frederick William was a read on incapacity, and incapacity is what creates a position that cannot be filled twice.
Second, count the alternatives before the salary. The condottieri were paid well and killed anyway. The only number that matters is how many other people could do this, and a strong master is defined by that number being high.
Third, become the sole supplier of one thing, visibly. Only Bismarck stood by him. Sole supply is manufactured by other people's absence as much as by your own presence, and the moments when everyone else withdraws are the cheapest time to acquire it.
Fourth, build the position rather than the relationship. The dependency survived a death and a hostile successor because Bismarck occupied a function, not a friendship. If your standing rests on someone liking you, it ends when they do.
Fifth — and this is where the honest reader has to make a decision — notice that Greene's rule is never teach them enough to do without you. Being genuinely indispensable and deliberately maintaining someone's incapacity are different things that feel identical from the inside, and only the first survives being seen.
And the plain statement: this is advice to seek out weak people, occupy the gap their weakness creates, and keep the gap open. It works, demonstrably. It also describes a great deal of what makes institutions bad at replacing anybody.
Strongest support. The Bismarck case is unusually well-structured for this book: a stated starting position, a counterintuitive choice, a documented method, and — crucially — a test in the form of a hostile successor, which the strategy survives. That last element is what raises it above anecdote.
Tension — the chapter cannot decide whether to build strength or withhold it. Bismarck restored the monarchy's power and made his master strong. The judgment says never teach them enough so that they can do without you. Those are opposite instructions, and Greene's own flagship case follows the first.
Tension — reverse independence is a tether described as freedom. The mechanism requires permanent availability. Greene contrasts it with a man in a cabin and never considers Kipling's cat, printed twelve lines away, who negotiates a bounded contract and keeps his autonomy.
Tension — the strategy's beneficiary is unexamined. Prussia got a competent minister; Frederick got a restored throne. It is not obvious anyone was harmed, which sits oddly with the withholding rule and suggests Greene has run together two different strategies under one law.

Open questions.
The chapter's Machiavelli epigraph runs the identical law in the opposite direction, and Greene prints it without comment:
Thus a wise prince will think of ways to keep his citizens of every sort and under every circumstance dependent on the state and on him; and then they will always be trustworthy.9
Greene's entire chapter is the servant making the master dependent. Machiavelli's line is the ruler making subjects dependent.
Same mechanism, same claim about necessity, opposite chairs — and the two are structurally at war. If Bismarck's strategy is sound, then Machiavelli's prince is running a counter-strategy against exactly that: a ruler who deliberately keeps everyone dependent is one who cannot be made dependent himself, because he has distributed his needs across a population rather than concentrating them in one indispensable minister.
So the law contains its own defence and does not say so. The countermeasure to a Bismarck is not to remove him — William tried and failed — but to arrange your affairs so that no single function is held by one person. That is an ordinary organisational practice, and the chapter, which is written entirely for the servant, never mentions that masters have a move.
It also means the law is not universal but positional: it works for whoever is currently the weaker party, and it is defeated by whoever thinks about structure first. The condottieri who open the chapter were destroyed by employers who had understood exactly this.

The case page carries the sequence in full — thirty-two and friendless, the deliberate choice of a spineless patron, the courtship, the ministry, the restoration of royal power, and the survival into a hostile reign.
What the pairing establishes, which neither does alone, is which variable actually carried the strategy.
The mechanism page says: select weakness, occupy the gap, withhold enough that the gap stays open. The case shows Bismarck doing the opposite of the third step — he made Frederick William strong, rebuilt the monarchy, and became more secure as a result.
The insight: it was never the master's weakness that protected him, it was the permanence of the threat environment. Frederick had enemies; William inherited "the same situation his brother had: enemies galore." Bismarck's function was handling them, and that function could not be exhausted, because enemies regenerate.
Which corrects the law in a usable way. Attaching to a weak master is a poor plan if the weakness is fixable — solve it and you are surplus. The durable version is to attach to a recurring problem, and the master's weakness matters only in that it makes them unable to solve the problem themselves. Greene selects for the wrong half of that and his own case demonstrates the right one.
→ psychology · Ingratitude and the Burden of the Favor
Law 2's mechanism: receiving a favour implies you were chosen rather than deserving, and the injury surfaces slowly as resentment — a debt is a weight the debtor is looking for a way to put down.
Read against this law, the two explain a puzzle neither raises.
Bismarck's kings disliked him. William "disliked Bismarck intensely" and kept him for decades, giving in "time after time." On Law 2's account that resentment should have been fatal — an obligation held that long, that visibly, is exactly the burden a debtor discards by removing the creditor.
It was not fatal, and the difference is what the two pages establish together: a favour creates a debt, which the debtor can discharge by destroying you; a dependency creates a need, which they cannot. Gratitude is retrospective and therefore cancellable. Necessity is prospective and renews every morning.
That is why Greene's fear over love instruction sits in this chapter rather than Law 2's, and it sharpens it. The claim is not really that fear beats love. It is that anything pointing backwards — gratitude, loyalty, past service — is a wasting asset, and only a live, ongoing requirement holds. The condottieri had the largest possible backward claim (they had saved the city) and it bought them nothing.
Sharpest implication. Greene's flagship case refutes his own operating rule. The judgment says never teach them enough so that they can do without you; Bismarck spent a decade making his weak king strong and rebuilt the monarchy — and became more secure, because his function was handling enemies and enemies regenerate. The durable form of this law is not withholding capability but attaching to an inexhaustible problem, and the two are opposite strategies that Greene runs together under one heading, recommending the fragile one and demonstrating the robust one.
