A peasant has an apple tree in his garden that bears no fruit. It serves only as a perch for sparrows and grasshoppers.
He decides to cut it down, takes his axe, and makes a bold stroke at the roots.
The birds and insects beg him to stop. Their offer is specific:
The grasshoppers and sparrows entreated him not to cut down the tree that sheltered them, but to spare it, and they would sing to him and lighten his labors.1
They would sing to him and lighten his labours.
He paid no attention to their request, but gave the tree a second and a third blow with his ax.1
Two more swings. He has now heard the appeal and rejected it twice more.
Then:
When he reached the hollow of the tree, he found a hive full of honey. Having tasted the honeycomb, he threw down his ax, and, looking on the tree as sacred, took great care of it.1
And Aesop's moral, stated outright:
Self-interest alone moves some men.1
This is why the passage earns its own page beside the chapter it decorates.
Law 13's thesis is that appeals to mercy and gratitude fail and appeals to self-interest succeed. The fable does not merely illustrate that — it runs both appeals on the same man, about the same object, minutes apart, which is a cleaner test than anything in the body text.
The failed appeal: song, and the lightening of his labours. Note that this is not nothing. It is a genuine offer of something pleasant, and the creatures are offering the only thing they have.
The successful one: honey, which he did not ask for, was not offered, and simply found.
Same tree. Same man. Same axe, mid-swing.
The obvious reading is that honey is worth more than birdsong. The fable is sharper than that, and the detail that proves it is the three blows.
The creatures made their case before the first stroke. He swung twice more.
So the appeal did not fail through being unheard, or through arriving too late, or through being outbid. It failed while being considered and repeatedly rejected, which means the peasant had already priced song and lightened labour and found them insufficient.
What changed was not the offer's value but its form. The birds proposed a future benefit contingent on his forbearance — a promise, requiring him to believe them and to wait. The honey was present, tangible, and already his, discovered rather than negotiated.
The peasant did not need to be persuaded, because there was nothing left to decide. Which is the fable's real content: the winning appeal was not an appeal at all.
The ending contains something the moral does not capture.
He does not merely stop chopping. He "threw down his ax, and, looking on the tree as sacred, took great care of it."
Sacred. He did not decide the tree was useful — he decided it was holy, and became its guardian.
That is a much larger shift than the discovery warrants. A rational peasant with a honey-producing tree keeps it and harvests it. This one reverses his entire relationship to the object, and the reverence arrives instantly.
Which suggests something the fable knows and Greene's chapter does not: self-interest, once satisfied, does not stay labelled as self-interest. It converts into value, attachment, even reverence — and the convert will not experience himself as having been bought.
That is why the technique leaves no residue. The Athenians who chose Corcyra did not think of themselves as mercenary; Genghis Khan sparing Kaifeng was not conscious of being managed. The person moved by their own interest re-describes the outcome as a judgement, and defends it as one.
Worth stating as the practical lesson, since it is the position most readers occupy.
The sparrows and grasshoppers made three errors, and only the third is fatal.
They offered what they had rather than what he wanted. Song is what a sparrow has.
They offered a future — they would sing — where he was acting in the present with an axe already in motion.
And they argued from their own need: do not cut down the tree that sheltered them. The first clause of their appeal is about their shelter, which is precisely Greene's diagnosis of how people ask badly — "they talk as if their needs mattered to these people."
The honey required none of this because it was not addressed to him at all. It simply was what it was, and he found it.
You are asking someone to spare something.
First, notice if you are offering what you have rather than what they want. Sparrows offer song. It is sincere, it is all they have, and it is not a reason to stop chopping.
Second, prefer the present to the promise. We would sing to you asks for belief and patience from someone mid-action. Anything already in hand outcompetes anything conditional.
Third, cut your own need out of the sentence. The creatures' appeal opens with their shelter. Whatever follows that opening is discounted, because the listener has already classified the request as being about you.
Fourth, look for the honey before you argue. The tree's real value was inside it the whole time and nobody — including the peasant, who owned it — knew. Before making a case for something, find out what it actually contains that the other party would want.
Fifth, expect the convert to be sincere. He called the tree sacred. People moved by their interests do not experience it that way afterwards, which is useful to know and worth not pointing out.
And the plain note: the birds were right that the tree was worth keeping, and being right did not help them at all.
Strongest support. A complete fable with a stated moral, from a named classical source, in which both appeals are run on the same target about the same object within a single scene. As a controlled comparison it is better constructed than any case in the chapter's body text.
Tension — the successful appeal is not an appeal. Nobody advocated for the honey. It was discovered. So the fable does not actually demonstrate that self-interest arguments succeed — it demonstrates that discovered value beats any argument, which is a different and less useful claim for someone who has to do the persuading.
Tension — the moral is narrower than Greene's use of it. "Self-interest alone moves some men" — Aesop hedges. Greene's chapter generalises to everyone, and only walks it back in the Reversal.
Tension — nothing here is about power. This is a fable about what motivates people, filed into a chapter about extracting help from superiors. The peasant has no relationship with the creatures and owes them nothing.
🚩 SECONDARY WITHOUT PRIMARY — attributed to Fables, Aesop, sixth century B.C.2 Named and dated, which is better than most of this chapter; no translator or edition given, and the Aesopic corpus is a tradition rather than a single authored text, so "sixth century B.C." attributes to a semi-legendary figure a fable whose surviving form is much later.

Open questions.
Set against The Nut and the Campanile Wall — Leonardo's fable from Law 10's margin — the two form a matched pair the build has now assembled across two chapters.
The nut appeals to compassion and piety, is granted shelter, and destroys the wall. The birds appeal to pleasure and mercy, are refused, and are saved by an accident.
In both, the appeal to good feeling is answered — and in both, what actually determines the outcome is something material the petitioner never mentioned. The nut's roots. The tree's honey.
The insight the pair produces: the stated appeal and the operative cause are unrelated in both fables, and the marginal column keeps making this point while the body text keeps writing chapters about how to phrase things.
Which is a real finding about the corpus. Greene's laws are overwhelmingly about presentation — what to say, what to conceal, how to frame. His marginal fables are almost all about structure — roots, honey, load, terms. The two halves of the book have different theories of what moves the world, and he never sets them against each other.
→ history · Corcyra Versus Corinth at Athens
433 B.C. Corinth gives a brilliant, passionate speech listing every past service to Athens and invoking Hellenic law and the duty of gratitude. Corcyra opens by conceding it has no friendship to offer and proposes only a fleet and a shared interest. Athens votes for Corcyra.
The fable and the debate are the same experiment at different scales, and together they isolate what actually failed.
Corinth's appeal was eloquent; the sparrows' was sincere. Neither quality helped, and both parties offered something genuinely real — real past service, real song.
The insight neither page produces alone: the losing appeal in both cases asked the listener to act on a relationship, and the winning one gave them something to act with. The Athenians were not moved by an argument about the future; they were shown a navy. The peasant was not persuaded; he was handed honey.
Which suggests that appeal to self-interest is a slightly misleading formulation of Law 13. The successful move in both cases was not a different argument — it was the presentation of an asset. Corcyra's ambassador spent most of his speech conceding weakness and one sentence naming a fleet, and the fleet did all the work.
→ psychology · Gratitude as a Burden, Not an Obligation
The psychology page carries the mechanism: a debt is a weight the debtor is looking for a way to put down, and naming it invites discharge — by devaluation, by removal, or, least often, by repayment.
The fable adds the missing bookend: what happens after the self-interested appeal succeeds.
The peasant does not experience himself as having been bought off. He calls the tree sacred and becomes its protector.
The insight the pair produces: the two directions are asymmetric in how they age. A gratitude-based bond decays into resentment, because the debtor carries a weight that grows heavier with acknowledgement. An interest-based bond appreciates, because the beneficiary re-describes his interest as a value and defends it as his own judgement.
Which is a considerably better argument for Law 13 than the one Greene makes. He argues the interest appeal works at the moment of asking. The fable shows it also produces a more durable relationship afterwards — the peasant tends the tree for years, and no one has to remind him why.
Sharpest implication. The creatures made their case and the peasant swung the axe twice more — so the appeal to mercy did not fail through inattention, it failed after being heard and priced. What ended it was not a better argument but honey, which nobody advocated for and which was simply found. The winning move in this fable is not an appeal at all, which is an awkward result for a chapter about how to ask, and points at the harder instruction underneath it: before making a case for something, find out what it actually contains that the other party would want.
Generative questions.
