Try to grab water. There is no handle. Press it and it parts around your hand; cup it and it drains through your fingers; dam it and it climbs the wall and goes over. The reason you cannot get a grip is not that the water is fast or strong. It is that it has no fixed shape for your grip to close on. The Questions and Replies arrives, at its summit, at exactly this image — Sun-tzu's "the army's disposition of force is like water"1 — and it gets there by dissolving the very categories the whole tradition was built on. The earlier teaching said: decide live which of your forces is orthodox and which is unorthodox. This page goes one step past that and removes the labels entirely. At the peak of skill there is nothing left to label. There is only water, and the enemy with nothing to grab.1
This is the apex teaching of the Questions and Replies, the most extensive unorthodox-theory discussion in the Chinese corpus.1 Its formula is six words in Sawyer's rendering: for the master of troops there are none that are not orthodox, none that are not unorthodox. Everything is both at once. And when everything is both, the enemy has no handle anywhere on you.
The companion page, Mutual Transformation, establishes that the orthodox/unorthodox labels are decided live, in contact, not stamped on troops beforehand. This page is the next and final move in the dialogue: at the highest level of mastery the labels do more than get decided live — they collapse. There is no longer a this-force-is-orthodox-that-force-is-unorthodox decision to make, because every force is simultaneously both.1
T'ai-tsung sets it up with a reframing question. "If I cause the enemy to perceive my orthodox as unorthodox and cause him to perceive my unorthodox as orthodox, is this what is meant by 'displaying a form to others'? Is employing the unorthodox as orthodox, the orthodox as unorthodox, unfathomable changes and transformations, what is meant by 'being formless'?"1 He has connected the orthodox/unorthodox machinery to Sun-tzu's two master ideas — giving shape to others (controlling the enemy's perception) and being formless (giving the enemy nothing to read).
Then comes the crux. T'ai-tsung asks where, if dividing and combining are just changes, the orthodox and unorthodox actually lie. Li Ching's answer is the apex line: "For those who excel at employing troops there are none that are not orthodox, none that are not unorthodox, so they cause the enemy never to be able to fathom them. Thus with the orthodox they are victorious, with the unorthodox they are also victorious. The officers of the Three Armies only know the victory; none know how it is attained."1
Sit with that last sentence. The master's own officers cannot tell which force was the decisive one. Not because they are stupid — Li Ching says comprehending this is something "no one has been able to attain" since Wu Ch'i — but because there is genuinely no fact of the matter to know. The win came from the orthodox and the unorthodox at once. The categories that the Hsin Shu tried to count out in advance, and that Mutual Transformation showed must be decided live, have here been transcended entirely. They were a scaffold. The building, finished, no longer needs them.1
The mechanism is a dissolution, and it runs in stages the dialogue lays out in order. Start with raw troops: you must give them fixed labels — this block is orthodox, that block is unorthodox — to teach them flags, drums, dividing and combining. Move to a trained army in battle: the labels go fluid, traded live as the enemy reacts. Move to the master: the labels vanish, because every element is doing both jobs simultaneously and the question "which one was the qi?" no longer has an answer.1
Li Ching grounds the apex in Sun-tzu's own words, which Sawyer places directly beneath it: "In accord with the enemy's disposition we impose measures on the masses that produce victory but the masses are unable to fathom them. Men all know the disposition [or form] by which we attain victory, but no one knows the configuration through which we control the victory. Thus a victorious battle strategy is not repeated; the configurations of response are inexhaustible."1
Two phrases carry the whole mechanism. First, the split between disposition and configuration — between the visible form by which you won and the invisible structure through which you controlled the win. Everyone can see the form afterward; no one can see the control. The form is the water's shape at the instant it struck; the control is the formlessness that produced that shape and is already gone. Second, "a victorious battle strategy is not repeated." Repetition is the one thing the master cannot afford, because a repeated form is a graspable form — a handle. The moment your win has a recognizable shape, your next enemy studies it and presses where it is weak. So the configurations of response must be inexhaustible, never twice the same.1
This is why the labels have to dissolve. As long as there exists a stable answer to "which is your orthodox and which is your unorthodox," there exists a shape an enemy can learn, anticipate, and prepare against. The categories are themselves a form — and form is the thing the master is shedding. Sun-tzu's capstone, which Sawyer quotes here, names the destination: "the pinnacle of military deployment approaches the formless."1 The aim is "give shape to others, be formless ourselves" — force the enemy into a readable disposition while you have none.1
The payoff is arithmetic, and Sawyer gives it bluntly. "If I determine the enemy's disposition of forces while I have no perceptible form, I can concentrate while the enemy is fragmented. If we are concentrated into a single force while they are fragmented into ten, then we attack them with ten times their strength."1 This is the one-versus-ten math, and it is the cash value of formlessness. An enemy who cannot read you cannot tell which of your forces is decisive, so he must defend everywhere — fragmenting into ten. You, who can read him, concentrate into one. Ten of yours against one of his at the chosen point. Formlessness is not mysticism. It is a force-concentration multiplier, paid for by being un-grabbable.
This page is the ceiling of the unorthodox tradition, the point its whole vocabulary was climbing toward. It connects to:
The case here is not a battle. It is a claim about knowledge, and the dialogue itself is the case study, so read the words closely. Li Ching's most arresting line is diagnostic: "The officers of the Three Armies only know the victory; none know how it is attained."1
Picture the aftermath of a battle the master won. His own subordinate commanders — men who fought it, who moved their contingents on his order — gather to reconstruct what happened. One says the flank cavalry won it. Another says no, the holding action at the center won it by fixing the enemy. A third says it was the timing of the reserve. And the point Li Ching is making is that all of them are right and none of them is, because there was no single decisive force. The center held and baited; the flank struck and covered; the reserve threatened and concealed. Every element was orthodox and unorthodox at once. There is no thread to pull that unravels the win into a "real" cause, because the win had no separable cause. "With the orthodox they are victorious; with the unorthodox they are also victorious."1
Now layer Sun-tzu underneath, as Sawyer does. "Men all know the disposition by which we attain victory, but no one knows the configuration through which we control the victory."1 The officers can see the disposition — the formation as it stood at the winning moment, the shape on the field. What they cannot see is the configuration of control: the live, formless reading-and-responding that produced that shape and was already dissolving as it formed. They are looking at the splash and trying to reconstruct the river. And the master could not draw them a diagram even if he wished to, because "a victorious battle strategy is not repeated" — the configuration that won was a one-time response to one enemy's one disposition, and it will never recur.1 The case study, in short, is an epistemic one: at the summit, victory becomes genuinely unexplainable, even to the people who executed it, because explanation requires a fixed form and the master has shed form on purpose. Sawyer notes the tradition's own frustration here — "Sun-tzu offers nothing more" past the principle.1
You are operating against an adversary who studies you — a rival firm, an opposing counsel, a competitor who has watched your last three moves. You feel the pull to find your "signature" move, your reliable decisive stroke, the thing you are known for. That instinct is the trap this page exists to break.
You walk into the engagement carrying no fixed answer to "which of my moves is the real one." You have several live elements going at once, and you have arranged them so each could be the decisive one depending on how the other side defends. You are watching them read you. The instant they treat one of your elements as your main effort and mass their defense against it, you let one of the others carry the win — and from their side, the force that beat them was indistinguishable from the force that merely fixed them. They cannot tell, afterward, which one was the knife. Neither, ideally, can your own team.
And you hold one discipline above all the others: you never repeat a winning shape. The proposal structure that won last quarter, the opening that worked last case — you retire it the moment it has a recognizable form, because a recognizable form is a handle and the other side is already studying it. You are water. You take the shape of the terrain in front of you this time, and a different shape next time, and you leave the opponent forced to defend against every probability at once while you concentrate everything on the one gap his fragmentation opens. He spread to ten. You came as one. That is the whole of it: stay un-grabbable, and let his need to defend everywhere do the dividing for you.
The apex teaching fails — collapses back down the ladder — in three telling ways:
The evidence is the Questions and Replies text in the Seven Military Classics, plus the Sun-tzu passages Sawyer arranges beneath it to show Li Ching grounding the apex in the Art of War.1
The tension Sawyer himself flags is the thinness of the foundation. After laying out the formless ideal, he notes: "despite the importance of the concept in the Art of War and subsequent theoretical manuals, Sun-tzu offers nothing more."1 The most exalted teaching in the tradition rests on a handful of aphorisms and a water metaphor, with no operational detail beneath it. This is a real problem, not a quibble: a doctrine that culminates in "be formless" and then declines to say how is structurally suspect. It may be the genuine ceiling of strategic insight — or it may be the point where the tradition runs out of sayable content and gestures at mystery to cover the gap.
🚩 Bias flag — Sawyer's pro-Chinese-distinctiveness lean. Sawyer presents the "none not orthodox, none not unorthodox" formula and the formless ideal as the high-water mark of a uniquely sophisticated Chinese theory of war. Keep two things separate. The historical fact: Li Ching, in the tenth century, articulated the dissolution of the orthodox/unorthodox categories into formlessness, grounded in Sun-tzu. That is well-sourced. Sawyer's thesis: that this represents a depth and self-awareness Western strategic thought never reached. That is the author's argument, and it leans on the very thinness he elsewhere admits — a doctrine that "offers nothing more" past the aphorism is being asked to carry a large claim about civilizational distinctiveness. A skeptic can read the apex as profound and read Sawyer's framing of it as over-reach, and both can be true.
An open question the dialogue leaves wide: is genuine formlessness achievable, or only approachable? Sun-tzu's own phrasing — the pinnacle "approaches the formless"1 — hedges. If even the master only approaches it, then "none not orthodox, none not unorthodox" is a limit, an asymptote, never quite reached. Which raises the sharper question: if no real army ever fully attained it, is the apex a description of mastery or an idealization the tradition told itself about its best commanders after they won?
Only Sawyer is cited, but the page stages Li Ching reading Sun-tzu, and the productive tension is between what Li Ching claims and what Sun-tzu actually supplied. Li Ching presents the formless apex as the culmination Sun-tzu intended — "only Sun-tzu was capable of comprehending the origins of dividing and combining."1 He positions himself as the faithful interpreter recovering the master's deepest meaning, against the simplifiers (the Three Kingdoms theorists who reduced "unorthodox" to "mobile troops that attack from the flank").
But Sawyer's editorial note quietly undercuts the claim of a fully-articulated doctrine: Sun-tzu "offers nothing more."1 So the convergence and the tension sit on top of each other. Li Ching and Sun-tzu converge on the destination — formlessness, the un-grabbable army, the win that can't be explained. They diverge in that Li Ching speaks as though this were a worked-out method handed down, while the textual record shows it as a luminous fragment that each later theorist had to inflate with his own elaboration. The tension reveals something about how strategic canons work: the highest teaching is often the least specified, precisely because it is doing the work of marking a horizon rather than giving instructions. Li Ching needs Sun-tzu to have said more than Sun-tzu said, because a tradition wants its summit to feel inherited rather than improvised. The boxer's coach insists every great fighter "had it" — that wordless thing — even though no two had the same it, and none could be taught it directly.
The move at the heart of this page — dissolving a dyad so the opponent has nothing to grab — recurs wherever one mind tries to become unreadable to another. The dissolution is structural, not particular to armies, and its clearest mirrors lie outside Chinese military history.
Together these three say the same thing from three angles: making yourself formless is making yourself un-attendable, and an un-attendable agent forces the watcher to fragment — at the sword, in the mind, and on the battlefield alike.
The Sharpest Implication If at the summit your own officers cannot tell how you won, then mastery at this level is fundamentally non-transferable. You cannot teach it directly, because teaching requires a repeatable form and the whole method is the refusal of repeatable form. This is a disturbing thing to admit about the highest reach of any skill: the better you get, the less you can explain, and the less you can pass on. The tradition can train the lower rungs — flags, drums, fixed roles — with great precision. The top rung it can only point at. "A victorious battle strategy is not repeated" is also a confession: the master's best work dies with the moment that produced it, leaving the officers, and history, only the splash and never the river.
