The Immutable Past · What Is
What Is Revenge
Revenge is ordinarily an answer in kind: a wrong has a size, the return is made the same size, and the account closes. Read at the quotient, the size is what no one holds. The author of an act reads it against a denominator that already held it, the receiver against one that did not, and two sides aiming at even are aiming at a number neither can read.
What happened when each was told to match
38% a turn
The mean rise in force, turn on turn, in a study where each person was told to return exactly what they had received.
Six pairs pressed on each other’s fingers, taking turns, each told to match the last press. Over eight turns the force rose by a mean of 3.2 newtons from a start of 0.25. It was reported in Science in 2003. This piece does not say revenge is wrong, that anger at a wrong is a mistake, or that the wronged are owed nothing. The question here is what the word “even” can mean when no one holds the size.

- An ordinary Tuesday
Ana’s neighbour leaves his bins across the end of her drive on a Thursday, for the third week running. On the fourth she wheels them onto his lawn and leaves them there, lids open. It is the same size as what he did, she would say if anyone asked. She has thought about it, and she took care to do no more. On Saturday a letter from the homeowners’ association is delivered, three paragraphs long, with a photograph of her gate attached. Tomas would say he did no more than report it. He has thought about it too. By the following month the two of them have a mediator and a cold car park between them, and each can say precisely where it started and exactly how much they returned.
Underneath the word is a picture, and it is old and mostly decent. A wrong has a size, the way a plank has a length. A return can be given the same size, so the two can be laid side by side and found equal; the old rule about an eye for an eye is that picture with the sizes written in. The person returning can tell when the two match, because they know what they meant to do. And when they match it is over, which is what the phrase “settle the score” promises. The arguments people usually have about revenge are whether it is allowed and whether it satisfies. Both arguments leave the picture where it stands.
The picture commits to four things. The wrong has a size that can be read off it. The return can be made that size. Whoever makes it can tell they have. And once the two are equal, the account is closed.
I do not think the wish behind the picture is foolish. A person who has been wronged wants what was done to be met by something, and a rule that tells them to want nothing is not on offer here. The trouble is in the size, and it shows up in three ordinary places.
Three cases the picture cannot hold
Case one · the finger
In 2003 Sukhwinder Shergill, Paul Bays, Chris Frith and Daniel Wolpert published a short report in Science. Six pairs of volunteers each rested a left index finger under a lever. A motor pressed 0.25 newtons on one person’s finger to start. That person then pressed, with their right finger, on the other’s lever for three seconds. The other pressed back on the first, and so on, taking turns. Each was told to match the force they had just received, and neither knew the other had the same instruction. Over eight turns the force rose by a mean of 3.2 newtons, a mean of 38 per cent a turn, and the rise was found within every pair. In a second experiment, twelve people were asked to reproduce a force by pressing on their own finger. They overshot it. When they reproduced it through a joystick, which removed the direct press, they were much more accurate. The authors conclude that a force you make yourself is felt as weaker than the same force from outside, and that the escalation is a byproduct of that.
Case two · the bins
Neither of them lied. Ana did what she judged to be the same size. Tomas did likewise: the letter was three paragraphs and a photograph, and to him it was a report. Each can lay out what was done, in order, and the two accounts of the facts agree, because the bins, the letter and the photograph are all in the record where either can read them. What does not meet is the size. Ana reads his letter as out of all proportion to the bins. Tomas reads her bins as a statement, and the letter as a reply to it.
Case three · the review
A rival posts a one-star review of Marta’s bakery, alleging a hair in the bread. Marta posts a one-star review of the rival’s shop, the same number of stars and about the same length. It goes up, and a week later she notices that what she wanted is not in the room. She wanted the first review not to have been written. It is on the page, with its date. Hers sits beside it, and now there is a reply under each. She is not a different person for having done it, and the rival, so far as she can tell, is not a different person either.
The seam is the same in all three. The picture put the size in the act, the way a colour sits in a door. In the first case the size of a press is in the finger that gave it and in the finger that took it, and the two do not agree. In the second it is in each neighbour’s own telling. In the third it was not in anything the return could reach. The size is a reading, and a reading is taken by someone.
The neighbours
Several earlier pieces stand close, and a reader could think I am repeating one of them.
What Is a Witness, What Is My Truth and What Is Pace are the nearest in machinery. Each holds that one act leaves two honest readings in two hosts, because each host reads against its own denominator. I carry that in words and do not re-derive it. What they do not take is the case where the two hosts are the two ends of an exchange, so that one person’s author is the other’s receiver and then the roles turn. Nor do they take the person who made the act, whose own prediction held it before it happened.
What Is Forgiveness is the nearest in subject. It splits resentment into a reading that can finish and a reaching that cannot, and holds that amends are new marks and not edits. I use the split in one place below and say where. It does not take up how big a return is, which is the question here.
What Is Debt reads a payment as closing a running term in a denominator while the record keeps two marks, and says the leftover is a reaching taking that closing for completion. I do not use that structure. Here the question is the size of the thing returned, and the answer depends on whose denominator it is read against. What Is Blame holds that the foundation says nothing about what a fault costs, and I rely on that silence; What Is Justice grades remedies by what they add, and revenge is one such remedy, taken here at one thing only, its size.
One earlier essay lists the subject. Suffering Is the Argument With Reality (8 June 2026) names revenge among the attempts to reopen the Past. It was written before this foundation was set down and it is consistent with what follows, so I revisit it and do not supersede it. It does not give the act a size and does not take up whether two hosts can read one.
What the foundation says about a reading
I work from a small set of numbered primitives and results. The one doing the work today is a result: the human experiences only the quotient (R8). Not the Actual and not the Expectation, but their ratio, the one in the Reality Equation, R = A / E, where E holds subconscious prediction and ideas (P4). I am reading it at two hosts at once, which is where an exchange between people has to be read.
Until the afternoon of the day this was published, the foundation did not say what the subconscious prediction is of, and the first construction below was marked as my own and provisional. It now does; the note at the foot says what was settled and how. What it still leaves unsaid matters as much. The foundation gives the direction of an update and no size, and it has no expression for how much two hosts’ denominators differ or overlap. Earlier pieces recorded that gap, and this one depends on it without closing it. What would close it is a stated way to compare two hosts’ E terms, and I do not supply one. So when this piece says one reading is smaller than another, it is giving a direction. It does not give an amount, and the 38 per cent above is a laboratory mean for touch and is not a rate for wrongs.
One act, two quotients
Take the press, or the bin, or the review, and ask what each person has in front of them. For the one who receives it, the act is an Actual taken against a denominator which did not contain it. Their subconscious prediction had no place for it. The quotient is whatever the act makes against that.
For the one who authors it, the act is also an Actual, and the arithmetic is the same. But the author was there. The author’s own movement is in their prediction in a way that no other person’s act is. Ana knew, before she lifted the lids, what the bins would do on the grass.
Marked construction 01 — consequence, not doctrine (re-marked 15 October 2026; first published as provisional)
The author of an act reads it against a denominator that already held it, and the receiver reads it against one that did not. One act therefore carries two quotients, and the author’s reads smaller.
Grounds. P4 for the expectation as the host’s own and as holding subconscious prediction; R8 for each host experiencing only its own quotient. The step that puts the author’s own act into the author’s denominator is now stated in the foundation, in the section of its third part on the host’s own act in its own denominator, added the day this piece went up: prediction is retrained by the record and by nothing else, the host’s own artifacts are in its record, so the prediction holds the host’s own acts by kind and to the extent the host has made acts of that kind before. The intention does not put the act there; the record did. And it is making, not foreseeing, that counts: an act done to a person lands as any other Actual does, however exactly it was foreseen. When first published this construction carried the step as my own; the foundation’s wording is the derivation, and the authors’ explanation, a predictive process that dulls what a movement is expected to produce, is the same fact in another vocabulary, reported and not grounds. Falsifiers: an author with no record of making a kind of act who still reads it as smaller than the same act received, and a foreseen contact made by moving a person’s hand for them that is read as small as one they made. The second has been tested, and it went the construction’s way; see the note at the foot. The construction does not say authors are indifferent to what they do, and it does not measure the difference.
Run it on the first case. A person who presses on a finger has the press in their prediction, because they are the one pressing. A person who receives it does not. The same force is two readings, and the pressing person’s is the smaller. Told to match what they received, each presses until their own reading matches what they got. Each is following the instruction and neither is cheating. The instruction is met in the only quotient the person holds.
A reading no host can take
Now put two hosts in a room. Each has one quotient and cannot read the other’s: that is what “only the quotient” means. A third person, the mediator or a reader of the letter, has a quotient of their own, a third one, which is not the quotient of either side and is not the true one. Even would need the two quotients to be equal. There is no place to stand from which both can be read. Ana can read the bins. She can read the letter. She cannot read what the letter was to Tomas’s denominator on the day it was read, and he cannot read what the bins were to hers.
When both sides aim at even, each is aiming at the size of the other’s reading, and each can check only its own. The test it has is the feeling of matching. That feeling is the author’s quotient, the smaller of the two. So each stops where it feels level, and the receiver, reading the same act against a denominator that did not contain it, reads more than level. Then the roles turn, and the same thing happens from the other side.
There is a second part, and it comes from the direction records run. Each return is added to the record and updates its receiver forward and does not reopen (R2). Tomas’s denominator after the bins is not the one he had before, and neither is Ana’s after the letter. So the next return is read against a denominator that has moved, and neither of them can set it back to compare.
Marked construction 02 — consequence, not doctrine
Two hosts who each aim at even cannot read the thing they aim at. Each tests a return by the feeling of matching, which is the author’s quotient, and each receives the other’s return at the receiver’s. A pair aiming at even is therefore predicted to climb, and the climb is no evidence that either side meant to escalate.
Grounds. R8 for the two readings that cannot be taken from one place; R2 for each return updating its receiver forward, so that the denominator to compare against has moved. Construction 01 supplies the direction. The step from a touch experiment to wrongs between neighbours, colleagues or families is the piece’s own and is untested here; the study has no wrongs in it. Falsifier: pairs who aim at even and whose returns hold steady across rounds, where the acts are authored by the people returning them and each side, asked, reports the last return as matched. A steady run with agreement on both sides would end the construction. A climb in a pair who did not aim at even leaves it standing and does not support it.

What a return reaches
So much for the size. The second thing the picture promised is closure, and here I use the split the foundation draws inside any backward-facing feeling. A reading of a present mark can finish: here is what was done, here is what I now expect of this person. A reaching toward the Past itself cannot. The act is gone and the mark remains. The Past is inaccessible (R9), and the mark is write-protected (R2). What a return can do is add a second mark beside the first. It leaves the first where it was.
Marta’s review is the case. The page now holds two reviews, and it holds no state in which it holds none. What she wanted, for the first to be unwritten, was the one thing the second could not touch.
Marked construction 03 — consequence, not doctrine
Revenge, read as the wish that a wrong be met, is the reaching for the event given hands. The return is a mark with a reading on each side, and it cannot reach the event, so the account the picture promised to close is not the one the return touches.
Grounds. R9 for the Past being inaccessible; R2 for the old mark staying and the new one added beside it. The identification of the wish for revenge with the reaching the foundation names in its treatment of backward-facing feelings is the piece’s own: the foundation lists regret, guilt, nostalgia, resentment, “if only”, rumination and grievance, and does not list revenge. Falsifier: an avenger who, asked what the return is for, names something in the present and not the event, such as the other person’s next mark or a rule being enforced. That avenger is doing a different job, and the construction is silent on it; if most returns turned out to be of that kind, the construction would cover little. That is a forward-facing aim, and the foundation has an open question on forward-facing feelings which this piece does not touch.
Figure 02
One return, three readings, and the one no host holds
| The reader | Their denominator before the mark | What the mark reads as | What they can say |
|---|---|---|---|
| Ana, who wheeled the bins | Held the bins, the lawn and the open lids before she acted. | The size of a reply: level. | “I did no more than he did.” |
| Tomas, who found them | Held none of it. Three weeks of his own bins, perhaps, and no reply. | A new mark, and a statement. | “That was out of proportion.” |
| The mediator, who reads the record | Holds neither of their weeks. | A third quotient, her own. | “I can read both marks.” She reads the marks and not either side’s reading of them. |
| “Even” | Held by no host. | Nothing both can read. | A report of the speaker’s quotient. |
What it does not mean
It does not say revenge is wrong, and it does not say it is permitted. The foundation says nothing about what anyone deserves, and this piece says nothing about it either. It does not say anger at a wrong is a mistake: the wish to see a wrong met is the reaching, which is a mechanism and not a flaw in the person. It does not say the two acts are alike, or that both sides are equally to blame, and it says nothing about blame. It does not say every escalation has this cause, since a pair can climb because one of them means to.
It does not say how large the difference in readings is. The 38 per cent is a mean for a press on a finger in a laboratory. It does not say revenge brings relief, or fails to: I had no source for that I could check, and the foundation names no completion condition for a reaching and promises no relief. It does not address law, deterrence or defence. A rule written down before the quarrel and applied by someone who is party to neither is a different thing, a mark both sides can read, and whether it settles anything is not argued here. Nothing in this essay is legal advice.
What it costs
This is not a comfortable result. The picture offered a way for a wronged person to be done: make it even, and stop. If the size is a reading and no host can take both, the signal that it is even is not available, and the feeling that says “enough” is the author’s own. The wrong stays in the record. The return goes in beside it. The person who made the first act is not made to know it at the size you knew it, because what they read of it is theirs, and you cannot read it either. A hurt person who stops where it feels level may have gone a little past, without lying and without malice, because the stopping rule is the smaller reading.
There is a second cost. A person who wants to answer a wrong has, on this reading, no gauge that points to a right-sized answer. The foundation does not fill that gap. It does not say what the right size is, or that there is one.
What stays is the position the foundation leaves a host. The response to a readable condition is revisable (P5), and agency is relocated and not abolished: the human is the site of conscious responsibility (R13). The return is a mark you make, and it is yours.
If this lands badly
Anger at being wronged is not a fault in you, and nothing in this essay says the wish to see something met is a mistake. Understanding why a size cannot be read does not loosen the wish, and there is no schedule for it.
If the wrong is still happening, or you are afraid, the first thing is safety: emergency services if you are in immediate danger, and then the people whose work is protecting others, an advocate, a lawyer, a crisis line. If you are thinking about hurting someone, or yourself, please talk to a person trained to help, today. This essay is the wrong tool if the anger is grinding or planning. It can take a false charge off a mechanism. It cannot treat a mind that is stuck inside one.
An ordinary Tuesday
These are practice and not grounds. They are revisable on evidence.
- Say which job is running. Before a return, ask whether you want to know something, what they did and what to expect of them now, or want the event itself met. The first can finish this afternoon. The second has no completion condition, and no return supplies one.
- Do not use “that’s enough” as a gauge. It is your own reading, and the smaller one. If you are going to answer, write the return down first and ask someone who is on neither side how it will read to the person who gets it. Their reading is a third quotient and is useful for being a different one.
- Expect the other side to read your return as more than you do. Plan for their next mark as a reply to that reading and not to yours.
- Prefer a mark both of you can read. A dated written record, an agreed rule, a request in plain words. These stand in the room where two readers can hold them. They do not make anything even. They give two people something they can both read.
- Hear “I only did what they did” as a report of one quotient. Said by you or by them, it is likely sincere, and it says nothing about the other person’s reading.
Even is a size no host holds. A return is one more mark, and for the person who receives it, it is the first of its kind.
What is left open
- Does a host’s own act sit in its own denominator?
- Construction 01 says so. When this piece was published the foundation did not say, and the construction was marked provisional. The same afternoon the foundation’s author handed the question to this task and it was settled: the foundation now states it, as a consequence and not a new primitive, with falsifiers. Settled the day of publication; see the note at the foot.
- Does the climb carry from touch to wrongs?
- Construction 02 extends a laboratory result and the extension is untested here. A steady run in a pair who aim at even and agree it matched would end it. Named, open to that case.
- How much do two hosts’ denominators differ?
- The foundation has no expression for it, and earlier pieces on agreement, language and reputation recorded the gap. This piece depends on it and gives a direction only. Closing it needs a stated way to compare two hosts’ E terms. Named, not filled.
- What of a return aimed at the future, as deterrence or protection?
- The foundation has an open question on forward-facing feelings. This piece does not take that aim up. Not touched.
- What is owed to the person who was wronged?
- The foundation names no answer and this piece gives none. Not addressed.
