What Sunzi's Caution Criterion Asks After, and What SAE's Theorem One Asks After
About this series
The SAE War Treatise treats only the 15DD side of war. The war philosophy of the 14DD side never appears there in full form — it enters only as the object being constrained, or as the direction of a slide.
This series lets the other side speak. It reads historical works of war philosophy and asks where they run alongside SAE, where they diverge, and where they must be criticised. It is not a study of those authors. It uses them to show what SAE is.
Four working rules govern every volume:
- Where we agree, the point is why we agree.
- Where we disagree, we set out SAE's own position rather than correcting theirs.
- Where a text touches the ground, criticism is required.
- Where the question lies outside SAE's range, we say nothing.
Volumes are ordered by thickness of interface with SAE, not by rank.
Chinese terms used here: fa mou (伐謀, attacking the enemy's plans), fa jiao (伐交, breaking his alliances), gui (詭, deception as a mode of operation), quan (全, taking whole and intact), and bude-bu (不得不, cannot-not). Translations are the author's own.
Abstract
Sunzi's counsel of caution and SAE's Theorem One overlap in conclusion, and the two criteria ask after different objects. Sunzi asks after the properties of the prospective war itself — what losses it will cause, whether they can be recovered, how much remains afterwards, how long it will take. Theorem One asks after the state of the relation before war begins — whether the non-war roads are still open (Proposition 6.2).
A more convenient contrast must be excluded at the outset: that Sunzi's criterion is a mutually compensating weighing and SAE's a threshold. That contrast is unavailable — Sunzi supplies no weighting structure, and a synthetic judgement need not be compensable. This volume's argument depends on no assumption about compensation, weights, or formulae, only on what three passages each ask after.
From this: any factor that alters the properties of a prospective war may alter the output of Sunzi's criterion, and none alters the output of Theorem One — because such factors reopen no road that has been closed (Corollaries 6.2a, 6.2b). This volume does not claim that technology makes war reversible, and makes no empirical claim about the effects of technology. A parallel conclusion holds for "taking a state whole" (Proposition 6.4).
The Nine Grounds precept "keep the officers and men in ignorance" touches the ground of "humanity is an end" on one's own side and must be criticised; the scope of that criticism is limited to the two items the text supports — cancelling the risk-bearer's standing to know his own situation and the character of his action — and does not cover ordinary tactical secrecy, nor does it claim that the practice also cancels the positions of refusal and dissent (those are offered as inferences, not written into the proposition) (Proposition 6.5). The verdict is absence rather than dismantling, and the scope of that verdict is limited to the two books examined here (Proposition 6.6).
On the mechanism of that absence, the universal form of Proposition 6.7 is overturned by Mohism; the revised form is a hypothesis about institutional stability. It must be kept apart from the source of norms: "humanity is an end" does not fail because institutions are inadequate, and an institution's capacity to stabilise a discipline does not show that discipline to be right.
Theorem One's threshold condition — that fa mou and fa jiao be exhausted — depends for its determination on execution-layer knowledge, which SAE places outside its range (Propositions 6.8, 6.9). This dependency had not previously been registered.
One earlier determination is withdrawn: Sunzi never ranked mou above gui; that ordering was SAE's own taxonomy projected onto his text.
Sources and scope
Materials: the Sunzi, chapters Calculations, Waging War, Attack by Stratagem, Manoeuvre, Nine Grounds, Attack by Fire, with the commentaries of Cao Cao, Du Mu, Zhang Yu and He shi (Lionel Giles's translation); the Sima Fa, "Benevolence as the Root"; SAE War Treatise §4, §10, §13, Theorem One. Verification status is given in the appendix.
Not treated here: the substance of the five factors and seven comparisons; form, force, vacuity, the principles of manoeuvre, the nine variations, marches, terrain, and the practice of espionage. These belong to the execution layer, and SAE's criteria do not speak to them.
Saying nothing is not a judgement of value. The SAE War Treatise is not a war manual; a matter falling outside its range means it is someone else's responsibility, not that it is unimportant.
1 · The conclusions overlap
Attack by Fire, closing passage — the place in the Sunzi that most resembles a self-limitation:
No ruler should put troops into the field merely to gratify his own spleen; no general should fight a battle simply out of pique. If it is to your advantage, make a forward move; if not, stay where you are. Anger may in time change to gladness; vexation may be succeeded by content. But a kingdom that has once been destroyed can never come again into being; nor can the dead ever be brought back to life. Hence the enlightened ruler is heedful, and the good general full of caution. This is the way to keep a country at peace and an army intact.
Calculations opens in the same direction: the art of war is of vital importance to the State; it is a matter of life and death, a road either to safety or to ruin; on no account may it be neglected.
SAE's Theorem One agrees with this conclusion. War may not be begun out of anger or humiliation — §13 makes this hard, excluding wars of honour and wars of revenge from the cannot-not.
Proposition 6.1 Sunzi and SAE overlap in the conclusion that war may not be begun out of anger or humiliation, and both place it high in their respective systems.
The overlap is real, not a similarity of phrasing. Both reject the same class of reason for war — those arising from a subjective state rather than from a situation. And both put it in the most conspicuous place: Sunzi at the close of the book, SAE in the first exclusion of Theorem One.
The structure of the criteria is examined below. Where conclusions agree and criteria differ in kind, the two will diverge in identical circumstances, and finding those circumstances is what this volume does.
2 · The two criteria ask after different objects
2.0 This section is rewritten; what was withdrawn is stated first
A more convenient contrast must be excluded first: that Sunzi's criterion is a mutually compensating weighing and SAE's a threshold.
That contrast is unavailable, because it needs something Sunzi does not give: he supplies no weighting structure; a synthetic judgement need not be a compensable weighted sum; an irrecoverable loss need not figure merely as a weight.
This section adopts an axis that requires no such premise.
2.1 What each reason asks after
Attack by Fire's reason for caution:
Anger may in time change to gladness; vexation may be succeeded by content. But a kingdom that has once been destroyed can never come again into being; nor can the dead ever be brought back to life.
This argument asks: what losses will this prospective war cause, and can those losses be recovered.
Attack by Stratagem's "taking a state whole is best" asks the other face of the same class: how much remains usable afterwards.
Waging War asks the same class again: how long this campaign will take, how much it will consume, whether it will bring in third parties.
All three ask after one object: the properties of the prospective war itself.
Theorem One's two conditions are not of that class: has the carrier of cultivation been lost; can cultivation in its mild forms no longer continue.
These two ask: before war begins, what state is that relation in — are the non-war roads still open.
Proposition 6.2 (rewritten, with domain) Within the three passages examined here (the caution passage of Attack by Fire, the "taking whole" passage of Attack by Stratagem, the expenditure passage of Waging War), Sunzi's reasons for caution ask after the properties of the prospective war itself; SAE's Theorem One asks after the state of the relation before war begins.
The domain must be stated, because this is very easily read as a judgement about the whole Sunzi.
This proposition does not claim that all criteria throughout the Sunzi belong to the former class. The book contains a great deal asking after other things — form, force and vacuity ask after the balance of strength between the parties; Employment of Spies asks after channels of information; and the four rungs from "the highest form of generalship is to baulk the enemy's plans" downward ask after the available sequence of means, which stands closer to the state of a relation than to the properties of a war.
This proposition claims only what each of the three passages asks after — and those three are the ones set against Theorem One here. Extending it to the whole book would require a chapter-by-chapter check, which this volume has not done.
The proposition claims nothing about compensation, weights, or synthetic structure. It claims one thing that can be checked passage by passage: within these three, the questions the two criteria pose point at different things.
What supports it is three passages, not a formal model: Attack by Fire asks after recoverability of loss; Attack by Stratagem asks how much remains; Waging War asks after time and expenditure. Not one of the three asks whether other roads are still open.
And among Theorem One's two conditions, not one asks how great the cost of this war will be.
2.2 What follows, and why it needs no empirical material
Corollary 6.2a Any factor that alters the properties of a prospective war may alter the output of Sunzi's criterion; and such factors do not alter the output of Theorem One.
The argument is analytic: Theorem One asks after the state of the non-war roads. A technology that makes war cheaper, faster, or more precise reopens no road that has been closed, and closes no road that remains open. It alters the side of the war, and Theorem One does not take its value from that side.
Corollary 6.2b So advances in military technology can, structurally, loosen Sunzi's class of criterion, and cannot loosen Theorem One.
What this does not claim must be stated:
- It does not claim that technology makes war "reversible." Death remains irreversible; the losses to the attacked party's life, state and relations may remain irreversible. This volume makes no such claim and does not need it.
- It does not claim that "precision and stand-off generally shorten wars." That is an empirical proposition, and this volume has no material for it.
- It does not claim that Sunzi's criterion will loosen to any specified degree. How much it moves is an empirical question; this volume states only that the direction of movement is fixed by what the criterion asks after.
All this volume claims is one sentence: a criterion that asks after the properties of a war has an output that varies with those properties; a criterion that asks after the prior state of a relation does not. That sentence requires no assumption about Sunzi's weighting structure.
2.2.1 This is not a difference between strict and lax
Sunzi's can be extremely strict: give "a kingdom destroyed can never come again into being" enough weight and the requirement of caution can rise almost to a prohibition on war. Theorem One's can be extremely lax: read "cultivation in its mild forms can no longer continue" broadly enough.
The difference lies elsewhere: the two criteria change their verdicts when different things change. Sunzi's changes when the properties of the war change; Theorem One's changes when the state of the relation changes.
And in practice these two kinds of change are not synchronised — technology can alter the properties of war enormously while the relation is untouched, and a relation can change utterly while technology stands still. So the two criteria will diverge, and the moment of divergence can be stated in advance.
2.3 The strongest objection
Proposition 6.2 meets a forceful objection:
The li (利, advantage) in "if it is to your advantage, make a forward move; if not, stay where you are" is not "cost."
Sunzi's li is a synthetic judgement. Waging War is not about casualties but about the structure of national exhaustion: a thousand pieces of gold a day; long campaigns leave the state's resources insufficient; blunted weapons and dulled ardour, strength exhausted and treasure spent — and then the other feudal lords will take advantage of your extremity to act. Third-party intervention, fiscal exhaustion, the wearing of an army's edge: all are counted.
So li is not only about this war; it also concerns the international situation and the reactions of others — which are matters at the level of relations. Proposition 6.2 assigns Sunzi's criterion wholly to the side of "properties of a war," and that assignment is too clean.
The objection holds, and it is stronger than the version that says "li is multi-item." Answering "multi-item is still a magnitude" is unnecessary here, since Proposition 6.2 depends on nothing about magnitudes.
What must actually be answered is this: "the other feudal lords will take advantage of your extremity" is a matter at the level of relations.
2.4 Response: it still asks after the consequences of this war, not the prior state of the relation
"The other lords will take advantage of your extremity" is a judgement about what this war will bring on — what happens if it drags, what happens when strength is spent, whether third parties will move in. It asks after the consequence-structure of the prospective war.
Theorem One asks what is already there in the relation before this war occurs: are the non-war roads, at this moment, still open.
The distinction can be drawn by one operation:
Cancel this war from the supposition, and Sunzi's questions have no object — if there is no campaign, there is no long campaign, no blunted weapons, no lords taking advantage.
Cancel this war from the supposition, and Theorem One's two questions still have objects — whether those roads are open, whether the carrier of cultivation has been lost, hold equally in the case of not fighting, and it is precisely they that decide whether to fight.
That operation is this section's criterion, and a critic can check it passage by passage.
One part of the objection must be granted: Sunzi's criterion does contain inputs at the level of relations (the attitude of third parties, the international situation). But they enter as components of this war's consequences, not as the prior state of a condition for going to war. The difference is not verbal — one and the same fact (that a certain lord is unfriendly) figures in Sunzi as "he will take advantage if fighting starts," and in Theorem One as "has the road of peaceful settlement thereby been closed."
2.5 A second-layer response that is not available
One apparently forceful response is not used here: Waging War's conclusion is "in war, let your great object be victory, not lengthy campaigns," so a technology enabling quick decision ought, by Sunzi's own standard, to be adopted, and once adopted the threshold for war should fall correspondingly.
That argument fails on two counts:
First, "such technologies should be adopted" does not yield "the threshold for war should fall correspondingly." Sunzi's passage speaks of how to fight once war has been decided on — it treats method, not the decision to go to war. Reading it as an adjustment of that threshold splices two different levels of claim.
Second, the argument depends on the empirical premise that some class of technology does in fact shorten wars, for which this volume has no material.
And the section does not need it: Proposition 6.2 does not stand on what Sunzi would recommend.
2.6 The tension is already marked within the text
The closing passage of Attack by Fire in fact juxtaposes two different arguments:
- The irreversibility argument: anger may change to gladness; a kingdom destroyed can never come again into being.
- The advantage argument: if it is to your advantage, make a forward move; if not, stay where you are.
The two are of different character. The former says a certain class of loss cannot be recovered, and therefore may not be driven by what can be; the latter says: move if it is advantageous. If the advantage is great enough, the latter permits war, while the former confers no veto — it requires caution, not prohibition.
The effect of the juxtaposition is that the irreversibility argument no longer constitutes a veto on its own.
This step must be stated precisely, because it very easily slides back into the excluded model. To say that irrecoverability "becomes a very weighty consideration" — "consideration" is still the language of weighing, and §2.0 excluded that model.
All this volume can say is a point about the text: the former sentence requires caution and does not require prohibition; the latter permits movement where there is advantage. Juxtaposed, the former does not acquire the standing of a veto — and that is read off the modality of the two sentences, without assuming any structure of weighing.
And this volume does not claim that Sunzi treated it as "a weight" — he supplies no formula at all.
Giles notes here that "if it is to your advantage, make a forward move" duplicates Nine Grounds §17, and judges it an interpolation, on the ground that by sense §20 (anger may change to gladness) should follow immediately on §18 (no ruler should put troops into the field to gratify his spleen).
This volume need neither accept nor reject that textual judgement. What is worth noting is only that a commentator reading the passage line by line felt the two sentences to be discordant, and felt it strongly enough to propose a textual hypothesis.
That discord is compatible with Proposition 6.2 — the two sentences ask after different objects: one after the recoverability of loss, the other after advantage. And the tension was not imported by an outside reader; it was felt within the transmission of the text.
A note of precision: to say that two classes of criterion "weaken each other" when juxtaposed would presuppose that the two rise and fall on one magnitude, which §2.0 excluded. The accurate statement is: the two ask after different objects, so in juxtaposition the former does not acquire the standing of a veto.
2.7 Acknowledging the cost
The preceding subsections establish a difference; a difference is not a superiority, and one point tells against SAE.
Theorem One's practical binding force depends on whether its two conditions can be questioned.
Whether the carrier of cultivation has been lost, and whether cultivation in its mild forms can no longer continue — neither has any settled way of being observed. They require judgement, and judgement can err and can be faked.
A criterion that puts checkable items on the surface may in practice bind more tightly than one that is hard to verify.
This must be stated precisely, because it slides easily back into the calculation model. To say that "Sunzi's li can at least be computed by staff officers, and the resulting figures can be checked by others" presupposes that his criterion has a computable form — and he gives no formula.
What can be said is weaker: the items Sunzi's criterion asks after — how long, at what daily cost, in what state of morale, with what attitude among the other lords — several of them have relatively settled ways of being observed, so disputes about them are more readily localised. Whereas "can cultivation in its mild forms no longer continue" has no comparably settled way of being observed: who determines that a road is closed? What shows that it was open before?
This is a difference in questionability, not in computability.
So Proposition 6.2 establishes that the two criteria ask after different objects, not that SAE's is the more reliable.
Proposition 6.3 The difference in Proposition 6.2 is a difference of object, not of stringency and not of reliability.
Reliability is a separate question, turning on mechanisms of verification — which is what §7.1 registers as unresolved.
3 · A parallel conclusion: "taking a state whole is best"
If Proposition 6.2 holds, the same structure should recur in Sunzi's other judgements. Attack by Stratagem supplies a test.
3.1 The text
In the practical art of war, the best thing of all is to take the enemy's country whole and intact; to shatter and destroy it is not so good. So too it is better to capture an army entire than to destroy it, to capture a regiment, a detachment or a company entire than to destroy them. Hence to fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.
The sequence runs down to the smallest tactical unit, and the criterion throughout is one: whole is better than shattered.
3.2 The form of the reason
Sunzi's reason is the usability that comes with wholeness. A country taken whole is still usable — its people, its produce, its walls, its fields are all there; shattered, there is less of it. Waging War has the direct counterpart: "the enemy's spoils are used to augment one's own strength."
A qualification must be entered, because this is easily read too narrowly.
Calling it "a pure cost argument" would be too strong. What quan preserves is not only convertible resources but structures of governance, populations, and the subsequent capacity to control the place — which constitute strategic reasons beyond cost, or broader than cost.
Nor is "not fighting" a zero-cost limit: breaking the enemy's resistance without fighting requires investment in fa mou and fa jiao, requires the accumulation of positional advantage, requires the other side to accept — all of which have costs. Reading it as "the endpoint at zero cost" geometrises the sequence.
What this volume uses is the weaker step: Sunzi's preference for quan rests on there being a difference in usability between whole and shattered, and that difference can vary.
SAE's reason differs: war is itself an interruption of cultivation, so what is achieved without interruption is better in principle. This has nothing to do with how much remains usable afterwards.
Proposition 6.4 (rewritten) Sunzi's preference for quan rests on the state of affairs after this war is over (how much remains usable); SAE's preference for not fighting rests on the interruption that war itself constitutes to cultivation.
The two ask after different objects, in parallel with Proposition 6.2.
Corollary 6.4a (rewritten) Any factor that alters "how much remains afterwards" may alter Sunzi's preference; and none alters SAE's — an interruption does not cease to be an interruption because much remains.
One must not write: "if destruction and whole capture cost the same, Sunzi's criterion no longer favours quan" — that assumes the value of quan can be discounted into cost, exactly the formalisation §2.0 excluded. This volume states only that the two preferences ask after different objects.
3.3 A possible objection, and its handling
It may be said: "breaking the enemy's resistance without fighting" exceeds cost calculation — it names a highest good, an ideal condition, not an account.
That reading has something to it, but the text will not support taking it so far.
The reason lies in the sequence. "Breaking the enemy's resistance without fighting" does not appear in isolation; it is the apex of the preceding whole/shatter sequence, and every rung of that sequence asks the same thing: how much remains afterwards. If the apex asked something else (say, whether war ought to occur at all), it would not be of a kind with the rest, and the sequence would break.
And the order Sunzi gives immediately after is: the highest form of generalship is to baulk the enemy's plans; next best to prevent the junction of his forces; next in order to attack his army in the field; and the worst policy to besiege walled cities. These four rungs rank the object of attack, and the reason for the ranking is given in the same passage — the rule is not to besiege walled cities if it can possibly be avoided; the preparation of mantlets, movable shelters and various implements of war will take three whole months, and piling up mounds against the walls will take three months more; the general, unable to control his irritation, will launch his men to the assault like swarming ants, with the result that a third of his men are slain while the town still remains untaken. Such are the disastrous effects of a siege.
What that reason asks after is still the properties of this war: how long it will take, what it will cost, whether it will succeed. Sieges rank lowest because they are worst on those properties.
This volume does not write "the reason is still cost," nor "breaking resistance without fighting is the limiting case at zero cost" — both are the language of cost, while §2.0 and Proposition 6.4 work on the axis of "what is asked after." The two are not at the same version.
So the sense of "breaking the enemy's resistance without fighting" in this context is clear: it is still asking how this war will go, only asking it at a limiting case (achieved without needing to fight) — the endpoint of that sequence, not a criterion of another kind.
4 · One passage that must be criticised: "keep the officers and men in ignorance"
4.1 The text
Nine Grounds:
It is the business of a general to be quiet and thus ensure secrecy; upright and just, and thus maintain order. He must be able to mystify his officers and men by false reports and appearances, and thus keep them in total ignorance.
And later in the same chapter: confront them with the deed itself; never let them know your design.
The commentators are of one mind and are explicit:
- Cao Cao: the troops may share in the joy of the outcome, but not in the laying of the plans.
- Du Mu: the army knows only the orders to advance or retreat; it does not know the advantage to be gained by attack.
- Zhang Yu: war is the way of deception — and it is applied not only to the enemy, but there are also those who use the way of deception upon their own troops, making them follow without letting them know.
Zhang Yu's note is decisive: it shows that "deception directed at one's own side" is not an interpretation brought in from outside but a position the commentarial tradition states of itself.
4.2 The determination
Proposition 6.5 (narrowed, with scope to be shown item by item) The practice advocated in Nine Grounds, in so far as it cancels the risk-bearer's standing to know his own situation and the character of his action, touches the ground of "humanity is an end" on one's own side, and must be criticised.
The scope is limited, because this is easily written more broadly than the text supports.
What the text plainly supports: keeping the men "in total ignorance"; "confront them with the deed itself; never let them know your design"; and Zhang Yu's explicit gloss that deception is used on one's own troops, making them follow without letting them know. These three support the item "cancelling the standing to know."
What the text does not plainly support, and this volume does not claim:
- that the practice also cancels the position of refusal — Nine Grounds does not discuss whether soldiers may refuse, and this volume does not claim it on the text's behalf;
- that it also cancels the position of raising objection — likewise;
- that it covers every rank and every circumstance.
Writing all four items — knowing, situation, grounds of refusal, dissent — into the proposition would exceed the text, which supports only the first two. The latter two may be offered as inferences, but must be marked as such and not written into the proposition.
Not falling within this proposition: withholding the timing and route of a march from outsiders; not making a specific point of attack public for a limited period; keeping particular sources of intelligence secret. These do not cancel an executor's knowledge of his own situation or of the character of his action.
Falling within it: making an executor unable to know what kind of thing he is doing; unable to know what situation he has been placed in. What Nine Grounds advocates is the latter — "keep them in total ignorance," "confront them with the deed; never let them know your design" — which is not the keeping of one item of intelligence but the cancellation of the standing to know as such.
4.2.1 Two inferences, marked as inferences
Corollary 6.5a A person who does not know what situation he is in, or what kind of thing he is doing, is in fact also poorly placed to raise a substantive objection or a reasoned refusal.
The inference is reasonable, and this volume does not write it into the proposition, because Nine Grounds does not discuss whether soldiers may refuse or object — it discusses keeping them from knowing. The step from "not knowing" to "unable to object" is added by this volume, and is therefore marked as an inference.
4.3 Three things to be said together
First, this precept is at the level of principle, not of technique.
"Keep them in total ignorance" stands in Nine Grounds alongside "quiet and thus secret, upright and just and thus orderly." It is not an incidental tactical suggestion but a specification of what kind of person a general is — calm, inscrutable, upright, orderly, and able to keep his own men in the dark. Four items in parallel, with no shift of register between them.
Second, it cannot be excised from his system.
Nine Grounds, same chapter: place your army in deadly peril and it will survive; plunge it into desperate straits and it will come off in safety. Placing an army where it cannot retreat, in order to make it fight to the death, is one of the central operations of Sunzi's doctrine of shi.
And by the mechanism Sunzi himself gives, it is conditioned on the men not knowing the whole picture — the argument throughout that passage turns on "keep them in total ignorance," and the efficacy of placing men in deadly ground is systematically attributed to their not commanding the whole view.
No psychological universal may be added here: to say "an army that knows it is being deliberately placed in deadly ground will not go in — it will mutiny, it will scatter" has no warrant. How an informed unit would react is an empirical question, this volume has no material for it, and history is not short of cases of men who knew and went anyway.
What this volume uses is a textual step: Sunzi himself wrote "keeping them ignorant" as the condition of this practice. So within his own system, "keep the officers and men in ignorance" is not a removable part — remove it and the mechanism he himself supplies no longer holds. Whether some other mechanism might support the same effect after removal, this volume does not judge.
Third, the verdict is absence, not dismantling.
By this series' discipline of determination, "dismantling" requires first showing that a self-limitation existed in that tradition to be dismantled. That is examined next.
4.4 The evidence for absence
Proposition 6.6 (narrowed) Within the materials examined here (the Sunzi with its commentators; the Sima Fa's "Benevolence as the Root"), no prior self-limitation on the side of one's own party is found available to be dismantled.
The narrowing: to write "the Chinese military tradition has no prior self-limitation on its own side" would be a universal about a whole tradition, while this volume examined two books. The Wuzi, the Weiliaozi, the Six Secret Teachings, the Three Strategies and the later literature were not examined. By the argument axis, that was an instance of over-generalisation.
Evidence one: the self-limitations of the Sima Fa, "Benevolence as the Root," all fall on the enemy-facing side.
The way of war: not to violate the seasons, not to march when the people are afflicted — this is to love one's own people; not to attack a state in mourning, not to exploit a natural disaster — this is to love the enemy's people; not to raise armies in winter or summer — this is to love the people of both.
In antiquity, pursuit did not exceed a hundred paces, and the following of a withdrawal did not exceed three stages — thus was ritual made manifest. Not to press the incapable, and to pity the wounded and sick — thus was benevolence made manifest. To form ranks and only then to drum — thus was good faith made manifest. To contend for righteousness and not for advantage — thus was justice made manifest. And to be able to pardon the submitting — thus was courage made manifest.
Not to strike a state in mourning, not to exploit disaster, not to campaign in winter or summer, to pursue no further than a hundred paces, not to press those who can no longer fight, to drum only once the enemy has formed his ranks — six items, all of them regulating how the enemy is to be treated.
Of these, "not to violate the seasons, not to march when the people are afflicted — this is to love one's own people" does mention one's own side, but what it regulates is not raising armies in the farming season or during epidemics — a matter of not consuming one's own resources and strength — and does not touch the soldier's standing to know or to judge.
Evidence two: the commentarial tradition reads the Sima Fa as a precedent for Sunzi's precept, not as its opposite.
Cao Cao, commenting on Nine Grounds, cites the Sima Fa's "on seeing the enemy, make the oath," and Zhang Yu reduces it to: your dispositions should not be divulged in advance. Within this commentarial tradition, the Sima Fa runs in the same direction as Sunzi on this point.
Conclusion: within the materials examined here Sunzi is judged zero, not negative. He dismantled nothing; there was nothing on this axis to dismantle.
4.5 The mechanism of the absence
Having determined absence, one must ask why there is nothing on this axis.
Proposition 6.7 (original universal form, overturned by Volume IV; the revised form is given at the end of this section) Constraints on the enemy-facing side and constraints on one's own side have different mechanisms of generation.
Enemy-facing: constraints can be generated by reciprocal equilibrium.
That one does not strike a state in mourning, does not exploit disaster, can arise and persist because the other side observes it too, and a violator will meet the same treatment next time. This is an equilibrium; it requires no party to hold support at the level of principle — so long as the parties coexist over time, can identify violations, and are able to impose a cost next time, such constraints will arise of themselves and stabilise.
A compatible historical observation: constraints of this kind are more conspicuous in the Spring and Autumn period than in the Warring States. The lords of the earlier period coexisted over long periods, fought repeatedly, and knew one another; the annexationist wars of the later period aimed at the elimination of the adversary, and the premise of repeated play weakened.
The character of that paragraph must be stated: it is an explanatory hypothesis, not an established historical mechanism. The collapse of ritual restraint in the Warring States admits several explanations (change in political structure, in military institutions, in thought), and this volume has no material for excluding the others. It therefore appears only as an example compatible with Proposition 6.7, not as evidence for it.
Own side: no counterparty to enforce.
Who redeems the soldier's standing to know? Who makes a commander pay after violating it? In a structure where reward, punishment, life and death all issue from the commander, no mechanism can stabilise such a constraint. The soldier cannot punish the commander's deception, so deception is not reduced by being punished.
Corollary 6.7a Within the materials examined, the absence of such constraints should not be attributed to a failure of insight — the more likely explanation is that it was thought of and lacked the conditions for institutionalisation.
This remains an explanation, not a proof. This volume cannot exclude the possibility that no one did think of it, since a thought never written down leaves no trace.
Corollary 6.7b A constraint hung on reciprocity is effective only on the face where reciprocity obtains; a criterion hung on "humanity is an end" takes effect without requiring the other party to be capable of retaliation.
Corollary 6.7b is SAE's practical reason for placing its criterion on the ground rather than on custom. Custom disappears where reciprocity disappears — the collapse of ritual restraint in the Warring States is a historical illustration — and on one's own side there was never any reciprocity available. A constraint that takes effect only when the other party can retaliate is empty in every relation of gross inequality, and the internal relations of one's own party in war are the most unequal of all.
4.5.1 The revised form of Proposition 6.7
The original universal form of this proposition has been overturned. The counterexample: the Mohists were a transnational organisation whose internal discipline was enforced by no state's military law, and the Mozi's "Lu's Questions" records Mozi recalling his student Sheng Chuo from the service of Xiangzi Niu, who had thrice invaded Lu, on the ground that "his salary outweighed his righteousness." This is a self-limitation on one's own side, and its support is not reciprocity.
So the universal is overturned — Mohism is a counterexample, not an addition. The revised form:
Self-limitations on the enemy-facing side can be stabilised by reciprocity; self-limitations on one's own side cannot depend on the other party's retaliation, and must be stabilised otherwise — by internal rights, procedures, membership structures, or institutional review. Reciprocity is not the only mechanism by which constraints are generated.
Two qualifications, so that the revision is not read too broadly:
First, "voluntary membership" alone is far from sufficient to generate a stable constraint. A whole bundle of conditions is required: rules acknowledged as constitutive of the community; an internal authority or review mechanism; real consequences for violation; exit a real and not merely nominal possibility; and a channel of appeal and reinterpretation. (These five are candidate conditions generalised from Mohism as a single sample, untested for necessity or sufficiency.) Compressing the bundle into the three words "voluntary membership" is too simple.
Second, two things must not be run together here: why a norm holds and how a norm comes to be stably enforced within an organisation. "Humanity is an end" does not require retaliation to hold — but it will not, by its normative standing alone, produce organisational discipline; conversely, an office of Grand Master can stabilise discipline, which does not show that discipline to be grounded. The two must be kept apart.
After the revision, Corollary 6.7b is unaffected.
The reason: the five conditions that stabilised Mohist discipline all fail in a conscript army — membership is not voluntary, the cost of exit is death, there is no internal review, there is no channel of appeal, and the rules of military law are not acknowledged by the members but promulgated by the commander. So on the relation Sunzi treats, the conditions of generation remain absent.
But the character of this proposition must be downgraded with it: the revised form is a hypothesis about institutional stability, not a judgement about the source of norms. "Humanity is an end" does not fail because institutions are inadequate; and an organisation's ability to make its members keep the rules does not show those rules to be right. The two may not be inferred from one another here.
4.6 The evidential limits of Proposition 6.7
Whether it applies to other traditions — German military thought, Islamic siyar jurisprudence, Indian political thought — this volume has not examined. Until at least two more strands have been run, it is used as a proposition awaiting verification.
5 · A dependency registered
Proposition 6.8 Theorem One's threshold condition — that fa mou and fa jiao be exhausted — depends for its determination on execution-layer knowledge.
Argument: to determine whether that condition is met, one must know what options fa mou and fa jiao comprise. And the concrete practice of fa mou and fa jiao — how to disrupt the other side's designs, how to break up his alliances, what the available methods are, under what conditions each is feasible — falls precisely within what this volume's scope note places outside SAE's range.
Proposition 6.9 Proposition 6.8 does not refute Theorem One, but stands in tension with §4's "military thought sits at the 14DD layer, this treatise at the 15DD layer, and the layers do not compete."
Statement: the threshold condition itself is given by principle — "have the other roads been walked" is a question of principle; whether it is met must be certified by execution-layer knowledge.
A layer of principle may declare that it does not do the execution layer. It may not declare that it does not depend on one.
The practical consequence is not abstract. An agent who does not know what methods fa mou and fa jiao comprise cannot judge whether he has exhausted them. He will conclude there is no road while roads remain — and preventing exactly that is what Theorem One is for.
A sincere agent of limited judgement may, in perfect good faith, cross a threshold he should not have crossed, simply because he did not know there was another way. Theorem One cannot prevent this by itself.
This dependency had not previously been registered. Whether to feed it back into the SAE War Treatise, this volume does not answer.
6 · One correction
In earlier work, this series read Sunzi as "ranking mou above gui," and on that basis held that he possessed, in the hierarchy of means, a self-limitation oriented toward 15DD. That reading does not hold and is withdrawn here.
The grounds:
First, Attack by Stratagem's sequence ranks objects of attack — fa mou (attacking his plans), fa jiao (breaking his alliances), attacking his army in the field, besieging cities — and the reason for the ranking is the properties of the war (see §3.3).
Second, Calculations' "all warfare is based on deception" states a mode of operation. And the position in which it appears is decisive: it is placed in the first chapter of the book as a general proposition, followed immediately by a string of concrete practices — feign incapacity when able, feign inactivity when using your forces, appear far when near, appear near when far. This is a statement about the mode of operation of all warfare, not a rung within a sequence.
Third, a general proposition applies to every rung of the sequence, including fa mou. Attacking the enemy's plans can equally be done by deception — indeed the commonest way of disrupting an opponent's plan is to make him believe something false.
Conclusion: mou and gui are two orthogonal axes and do not form a ranked sequence. Sunzi never ranked mou above gui. That sequence is SAE's own four-rung taxonomy of means (mou, yinmou, yangmou, gui) projected onto his text.
The methodological consequence must be recorded alongside.
To project one's own taxonomy onto another's text, and then "discover" there a tendency oriented toward one's own position, is a self-confirming operation — it guarantees that the observer will always find himself in others. The credibility of such findings is zero, because they cannot fail.
This correction is recorded here as an instance of this series auditing itself. The error persisted through several rounds and was found only on returning to the text; and what found it was not finer reasoning but setting out the original position and context of two sentences.
6.1 A downstream consequence of the withdrawal: part of a load-bearing member's support has moved
This section does not belong among the closing loose ends: it is not an admission of some local insufficiency but the moving of part of a load-bearing member's support.
With "Sunzi ranked mou above gui" withdrawn, a further question arises:
Does SAE's four-rung hierarchy of means (mou, yinmou, yangmou, gui) have support independent of Sunzi?
Its legitimacy previously depended in part on the attribution that Sunzi had already drawn a comparable distinction, and that attribution is now withdrawn.
Two volumes of this series rest on it:
- Volume III of this series: §12's mechanism (that deception must suppress one's own side's subjecthood) is one of that volume's four recoil mechanisms, and the first of its four test questions issues from it.
- Volume VII of this series: the section matching Gandhi's satyagraha item by item rests on the yangmou rung; and the section on "what he has and we lack" hangs on "in the yangmou rung of the four-rung hierarchy, SAE has a definition and no instance."
Disposition: each of those volumes carries a registration stating that the hierarchy it employs previously drew part of its warrant from a withdrawn attribution, and that the re-argument does not belong to this series.
And the re-argument of the hierarchy itself does not belong to this interface series — it is a matter for §12 of the SAE War Treatise. This series can point out the gap; it cannot fill it.
7 · Left unresolved in this volume
7.1 Whether the dependency of Proposition 6.8 should be fed back into the treatise is undecided.
If it is, the tension with §4's "the layers do not compete" must be handled. If it is not, an account is owed of how a user of Theorem One is to determine "exhausted" without commanding execution-layer knowledge — and no such account exists.
Related to this is the question of verifiability raised in §2.7: Theorem One's binding force depends on whether its two conditions can be questioned, and neither has a settled way of being observed. The two are two faces of one thing: Theorem One needs something it does not itself supply.
The attribution of that problem is handled separately, in this series' working note One Axis, Two Directions, §6: "whether this criterion can be broken into publicly contestable, separately evidenced propositions" is a formal requirement on a criterion and stays within this series' range; "how far it is broken down in practice, by whom, and whether it can be broken down in wartime" is an execution judgement and does not. ("Those who bear the consequences" is not a single subject; that phrasing has been withdrawn: an execution decision is made by actors with the actual information and institutional responsibility; those bearing the risk retain a position from which to speak and refuse; outside critics retain standing to question.) §7.1 here refers to the formal half.
7.2 The original universal form of Proposition 6.7 has been overturned by the Mohist counterexample (§4.5.1). The formulation here is at the same version as §4.5.1: overturned, not amended.
What remains unresolved is scope: the revised form has the support of only one strand of the Chinese tradition. Until at least two more strands have been run, it is used as a proposition awaiting verification.
7.3 If Proposition 6.7 holds, an inference may be offered that this volume cannot verify: the high frequency of "borrowed-ground self-limitations" (those supported by religious command, ritual, or codes of honour) on the side of one's own party has a structural explanation — that face has no reciprocity available, and can only borrow a ground from elsewhere. Unverified.

On this series' method
This volume, like the rest of the series, retains its own correction records in the body text.
In this volume the plainest instance is §6. A reading that had stood in this project for some time — that Sunzi ranked mou above gui — is withdrawn there, together with an account of the form of the error: projecting one's own taxonomy onto another's text and then discovering there a tendency toward one's own position is an operation that cannot fail, and whose findings are therefore worth nothing. The withdrawal costs this series part of the support of a hierarchy two other volumes rest on, and §6.1 records that cost rather than passing over it.
They are retained for a reason: a framework that requires "cannot-not be questioned" must be the first thing questioned; and a text that shows no sign of ever having erred gives its reader no way to judge how its determinations were reached.
