The starting point of the instruments

Sun Tzu, The Art of War

謀攻  Móu Gōng  — chapter three, closing passage

The most quoted sentence in the book is also the most mistranslated, and the two words that got changed are exactly the ones a coach needs.


The mistranslated words: what the English language did to it.

  1. 知彼知己,百戰不殆
    Zhī bǐ zhī jǐ, bǎi zhàn bù dài
    Know the other and know yourself: a hundred battles, no peril.
  2. 不知彼而知己,一勝一負
    Bù zhī bǐ ér zhī jǐ, yī shèng yī fù
    Not knowing the other but knowing yourself: one victory, one defeat.
  3. 不知彼不知己,每戰必殆
    Bù zhī bǐ bù zhī jǐ, měi zhàn bì dài
    Knowing neither the other nor yourself: every battle, certain peril.

How the translation into English reads

Lionel Giles published the standard English translation in 1910, and it's been the basis of nearly every version since. This passage is chapter III, line 18.

Giles was a serious scholar and most of his work holds up. Two choices in this passage don't, and because his rendering became the source of every poster, keynote slide and management paperback that followed, the errors have had a century to harden into common sense.

CharacterWhat it meansWhat the English saysWhat that changes
彼 bǐ The other. That one. The other party. the enemy A neutral word becomes an adversary. The reader is handed a fight that isn't in the sentence.
殆 dài Peril. Danger. Being cornered. succumb, defeat A promise about safety becomes a promise about winning, which the text never makes.

The first word

彼bǐ — the other

There's no enmity in this character. It's the ordinary word for the other party, that one over there, the one who isn't you. Sun Tzu is writing a military treatise, so an army is often what he has in mind, but the word he chose doesn't say so, and choosing it was not an accident in a text this economical.

Read it as written and the sentence stops being about opponents. It becomes about the difference between the two things a person can know: themselves, and someone who is not themselves.

For a coach, the other is not the opposing team. . It's about the athlete standing in front of you.

That reframing is not a liberty taken with the text. It's what happens when you take the interpolation (inserting something new or estimating an unknown value that lies in between known data points or text) back out.

The second word

殆dài — peril

Sun Tzu does not promise a hundred victories. He promises that across a hundred engagements you will not be in danger. Not caught out, not cornered, not surprised by something you should have seen.

That's a far more modest claim, and a far more useful one. It's also a claim about perception rather than about force.

The whole of chapter three argues that the highest skill is not winning battles at all. Its most famous line is that subduing the other without fighting is the summit of the art. The passage at the end isn't a victory formula bolted onto that argument. It's the conclusion of it.

Whoever turned no peril into a hundred wins inverted the chapter while quoting it.

The middle clause

Knowing yourself but not the other: win one, lose one

This is the honest description of most coaching, and it's the clause nobody quotes.

A coach can be self-aware, reflective, clear about their own patterns and values, and still get inconsistent results, because self-knowledge only covers half the equation. The other half is the person in front of them, and that half is not obtained by thinking harder.

Win some, lose some, and no clear reason why. If that describes your season, the missing term is 彼.

Why this grounds the instruments

Two kinds of knowing, and everything here serves one or the other.

知己 — knowing yourself

Inner truth. The alignment of thinking, feeling, speaking and acting, and the discipline of noticing your own flinch before it becomes a judgment about someone else. Without it, everything you perceive arrives coloured and you don't know it.

知彼 — knowing the other

This is the harder half and the one coaching education neglects. Not analysis of the other, not a model of the other, not a category the other fits into. Perceiving what's actually there. Miksang trains it on a single play. Nunchi widens it to a room.

A hundred engagements without peril isn't a promise of results. It's a promise about not being caught out, and that's precisely what perception training offers.

Every instrument on this site sits under one of those two characters. That's the reason the passage opens the material rather than decorating it.

Read the two disciplines that serve the second character.
