The Art of War, Chapter 1: 始計 (Laying Plans)

Chapter 1 is the shortest argument in the book and the one the other twelve depend on: decide whether to fight, and on what terms, before anything is committed. That is also the shape of an investment committee paper, so this is where the reading starts.

Each chapter in this series has the same three parts: the reading, an analysis of what the chapter argues, and how finance professionals can interpret it in their own work.

The original text below follows the Chinese Wikisource edition of 《孫子兵法》. The Chinese and English explanations are Claude’s own paraphrase, not a translation line for line. Where a reading is contested, Claude says so.

Reading the chapter

1.1

原文

孫子曰：兵者，國之大事，死生之地，存亡之道，不可不察也。

中文解說

孫子說：戰爭是國家的頭等大事，關乎人民生死、國家存亡，所以不能不審慎地觀察和研究。

全章的重點落在最後一個字：察。

English

War is a matter of the first importance to a state. It decides who lives and who dies, and whether the state survives. It has to be examined, not assumed.

The operative word is 察, to inspect closely. Everything else in the chapter is a method for doing that.

1.2

原文

故經之以五事，校之以七計，而索其情：一曰道，二曰天，三曰地，四曰將，五曰法。

中文解說

所以要用五個方面來衡量，再用七項比較來對照雙方，從而探求實際情況。五個方面是：道、天、地、將、法。

English

So assess the situation on five factors, compare the two sides on seven measures, and work out the real position. The five factors are the way (道), heaven (天), earth (地), the commander (將) and method (法).

1.3

原文

道者，令民與上同意，可與之死，可與之生，而不畏危也。天者，陰陽、寒暑、時制也。地者，高下、遠近、險易、廣狹、死生也。將者，智、信、仁、勇、嚴也。法者，曲制、官道、主用也。凡此五者，將莫不聞，知之者勝，不知者不勝。

中文解說

道，是讓民眾與君主同心，願意同生共死而不怕危險。天，指晝夜、寒暑、四時節候。地，指地勢的高低、路程的遠近、地形的險易與寬窄。將，要有智謀、誠信、仁愛、勇敢、嚴明。法，指軍隊的編制、將吏的管理和軍需的供應。

這五方面，每位將領都聽過，但真正理解的人才會勝。

English

The way is whether the people and the ruler share one purpose. Heaven is timing and conditions. Earth is terrain: distance, difficulty and room to manoeuvre. The commander is judged on wisdom, credibility, humaneness, courage and discipline. Method is organisation, chain of command and logistics.

Every general has heard of these five. The ones who understand them win.

1.4

原文

故校之以七計而索其情，曰：主孰有道？將孰有能？天地孰得？法令孰行？兵眾孰強？士卒孰練？賞罰孰明？吾以此知勝負矣。

中文解說

所以用七項比較來探求實情：哪一方的君主更得人心？哪一方的將領更有能力？哪一方佔了天時地利？哪一方的法令更能貫徹？哪一方的兵力更強？哪一方的士卒更訓練有素？哪一方的賞罰更嚴明？我憑這些就能預知勝負。

English

Then compare both sides on seven questions: whose leadership has the people's trust, whose commander is more capable, who holds the advantage of conditions and terrain, whose rules are actually enforced, whose forces are stronger, whose people are better trained, and whose rewards and penalties are clearer. These answers tell you who is likely to win.

Notice that all seven are comparisons. A strength only counts relative to the other side.

1.5

原文

將聽吾計，用之必勝，留之；將不聽吾計，用之必敗，去之。計利以聽，乃為之勢，以佐其外。勢者，因利而制權也。

中文解說

如果將領肯聽我的計謀，用兵必勝，就留用他；不肯聽，用兵必敗，就辭退他。計謀有利而被採納後，還要造成有利的態勢，作為外在的輔助。所謂「勢」，就是依據有利的條件，靈活地掌握主動。

English

A commander who follows this plan will win and should be kept. One who ignores it will lose and should be let go. Once a plan is accepted, build momentum around it. Momentum (勢) means using the advantage you have to keep the initiative.

The line about keeping or dismissing the commander is about accountability to the plan, which is why it reads well as a rule for deal teams.

1.6

原文

兵者，詭道也。故能而示之不能，用而示之不用，近而示之遠，遠而示之近。利而誘之，亂而取之，實而備之，強而避之，怒而撓之，卑而驕之，佚而勞之，親而離之。攻其無備，出其不意。此兵家之勝，不可先傳也。

中文解說

用兵是一種詭詐之道。有能力要裝作無能，要出擊要裝作不動，近要裝作遠，遠要裝作近。對方貪利就引誘他，對方混亂就攻取他，對方實力充足就加強戒備，對方強大就暫時避開，對方易怒就去激怒他，對方輕視我就使他更驕傲，對方安逸就設法使他疲勞，對方團結就設法離間。攻擊他沒有防備之處，出擊在他意料之外。這是兵家取勝的奧妙，事先是無法說定的。

English

War rests on deception. Appear weak when strong, inactive when active, far when near. Bait the greedy, take advantage of disorder, prepare against the strong, provoke the quick-tempered, flatter the arrogant, tire the rested, and divide the united. Strike where the other side is unprepared.

This is the line most often quoted out of context. It describes an adversary at war, and it is not a licence to mislead a counterparty in a transaction. The analysis below returns to this point.

1.7

原文

夫未戰而廟算勝者，得算多也；未戰而廟算不勝者，得算少也。多算勝，少算不勝，而況於無算乎？吾以此觀之，勝負見矣。

中文解說

還沒開戰，就在廟堂上籌算而認為能勝的，是因為具備的有利條件多；籌算後認為不能勝的，是因為有利條件少。籌算周密的能勝，籌算粗疏的不能勝，何況根本不籌算呢？從這些來看，勝負就清楚了。

English

Before the battle, the side that wins the calculation in the war council has counted more factors in its favour. The side that loses it has counted fewer. More calculation wins, less calculation loses, and no calculation loses most of all. Look at it this way and the outcome is visible in advance.

Analysis: what the chapter argues

The decision comes before the action. 1.1 sets the tone: war is too costly to enter on instinct, so the first job is to examine it (察). The rest of the chapter is a method for that examination, not for fighting.

The method is structured, then comparative. The five factors (1.2 and 1.3) describe the situation. The seven questions (1.4) put the two sides next to each other. Sun Tzu does not ask whether you are strong. He asks whether you are stronger than the other side on each measure.

The factors are not all material. Only two of the five, earth and heaven, are physical conditions. The way, the commander and method are about alignment, people and organisation. The chapter treats those as equal to terrain and timing, and that is the part most often skipped when a plan is made in a hurry.

The count has to be done before the commitment. 1.7 says the calculation made in the war council, before the battle, predicts the outcome. More factors counted in your favour means a better chance. A missing count is the worst position of all.

A plan has to be adopted to matter. 1.5 ties the quality of a plan to whether it is followed, and says momentum (勢) has to be built around it. A good analysis that the commander ignores has no value.

Deception is a tactic, not the foundation. 1.6 comes after the analysis, not before. It describes posture toward an adversary once the real assessment is done. It does not replace the assessment.

A note on reading 詭道. It is a description of an adversary at war. Claude does not read it as a licence to misstate facts or hide what you are obliged to disclose. The site owner’s essay Playing the rules, not breaking them covers the related gap between playing the rules and gaming them.

How finance professionals can read it

This section is Claude’s interpretation. Sun Tzu wrote about armies, and none of the mappings below are his.

Investing

• Test the decision, not just the target. 1.1 asks whether the decision deserves the commitment at all. An investment committee paper that begins with the target and not the question (“should we be in this at all, at this price, at this time?”) skips the first step.
• Use the five factors as a diligence frame.

Sun Tzu	Original sense	In an investment decision
道 The way	Shared purpose between ruler and people	Do management, owners and the board want the same outcome, and do they want it as much as you do?
天 Heaven	Timing and conditions	Cycle, rates, liquidity, sentiment and the regulatory calendar. This is the exogenous layer.
地 Earth	Terrain	The structure of the market the target sits in: competitors, customers, supply chain, barriers to entry and exit.
將 Commander	Wisdom, credibility, humaneness, courage, discipline	The quality and track record of the people who will run the asset after you close.
法 Method	Organisation, command, logistics	Governance, controls, reporting, systems and how the business actually executes.

• Compare, don’t just score. A deal is judged against the next best use of the capital. Run the seven questions against the alternative you could fund instead.
• Count the commitment, not only the price. The cost of a deal includes liabilities and upkeep after closing. A valuation model on its own covers a fraction of what 1.7 asks you to count.

Raising funds

• The seven questions apply to the capital as well as the company. Whose investors are better aligned, whose terms are clearer, and who can fund certainly rather than hopefully?
• Know the other side’s position. Before approaching investors, work out what each one has funded before, what its portfolio needs, and where it is in its own cycle. That is 地 and 天 from the investor’s side.
• A raise is a plan that has to be followed. Agree internally what you will concede and what you will not before the first meeting, as 1.5 implies.

M&A

• Inspect the counterparty’s motive. Why is this party buying or selling now? The answer is the 道 question about their side of the table.
• Compare your position with the rival bidder. Funding certainty, speed, integration capacity and willingness to take on liabilities are the 兵眾, 士卒 and 法令 questions.
• Decide the walk-away price in advance. 1.7 argues that a decision is made in the calculation, before the engagement, not under pressure in the negotiation.
• Choose posture deliberately. What you reveal, and when, is a legitimate part of negotiation. Misstating facts or exploiting a process against its purpose is not.

Across all three

• Write the count down. A decision held in the head cannot be tested later.
• Record who is accountable for following the plan. 1.5 ties the quality of the plan to whether it is followed.
• Be specific about what would make you walk away. If you cannot name it before the deal starts, you probably will not walk away.

Questions to carry into the next chapter

Chapter 2 (作戰) moves from deciding to fight to paying for it. It is the chapter about cost, duration and logistics.

• Which of the five factors do you most often skip when you are in a hurry?
• Do you write down the seven comparisons, or do you hold them in your head?
• What would make you walk away from your current deal, and have you written it down?
