In one line
Sun Tzu is the traditional author of The Art of War (Sunzi bingfa), the most famous book on strategy ever written. Short, cold and practical, it teaches preparation, knowledge, deception and economy of force, and it insists again and again that war is costly and the wise general wins with as little fighting as possible.
The life
Sun Tzu means "Master Sun." His personal name, according to tradition, was Wu. Almost everything said about him comes from one short biography in Sima Qian's Records of the Grand Historian (Shiji, chapter 65), completed around 94 BC, centuries after the events it describes.
Sima Qian says Sun Wu was a man of Qi who came to King Helü of Wu, who reigned from 514 to 496 BC, with his book of thirteen chapters. The king had read them and wanted a demonstration: could Sun Wu train women as soldiers? Sun Wu said he could. The king sent out 180 women from the palace. Sun Wu divided them into two companies, put the king's two favorite concubines in command, and explained the drill. When he gave the signal, the women laughed. He said that if orders are unclear, it is the general's fault; he explained again. When he signaled a second time and they laughed again, he said that if orders are clear and not carried out, it is the officers' fault, and he ordered the two commanders beheaded. The king, watching from a terrace, sent word begging him to spare them. Sun Wu replied that once he had received the command of the army, there were orders from the ruler he did not have to accept. He executed them, appointed the next two, and the women drilled in perfect silence. Sima Qian adds that Helü made him a general, and that Wu went on to defeat the powerful state of Chu and capture its capital.
It is a vivid story, and it may not be true. The Zuo zhuan, the older and detailed chronicle of the period, which describes Wu's war against Chu in 506 BC, never mentions Sun Wu. For this reason many historians doubt he existed as described, or think the figure was built around a real but obscure officer. The book itself refers to warfare on a scale, with large conscript armies and long campaigns, that fits the Warring States period (475 to 221 BC) better than the late 6th century. Most scholars now date its composition to somewhere in the 5th or 4th century BC, likely shaped by more than one hand.
Sima Qian also mentions a descendant, Sun Bin, a strategist of the 4th century BC who wrote his own book on war. For centuries some scholars suspected the two were the same man. In 1972, archaeologists excavating Han dynasty tombs at Yinqueshan in Shandong found bamboo slips holding both texts, the Sunzi and a separate Sun Bin bingfa, settling that they were two different works.
The text we read has thirteen chapters, as Sima Qian said. Its standard form owes much to the warlord and poet Cao Cao (AD 155 to 220), whose commentary is the oldest that survives. A French Jesuit, Jean Joseph Marie Amiot, brought it to Europe in 1772. The first English translation, by Everard Ferguson Calthrop, appeared in 1905; Lionel Giles's more accurate translation of 1910 is the one most people still meet online.
The big ideas
War is a grave matter
The book opens (chapter 1) by saying that war is a matter of life and death for the state, the road to survival or ruin, and must be studied with care. Nothing in The Art of War treats fighting as glorious. Chapter 2 counts the cost of an army in silver and grain, and warns that no country has ever benefited from a long war.
Win without fighting
The book's central claim comes in chapter 3. In Giles's 1910 translation: "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 best strategy attacks the enemy's plans; next best, his alliances; then his army; and worst of all, his walled cities.
Know the enemy, know yourself
Also chapter 3, in Giles: "If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle." The often-quoted first sentence is only a third of the lesson. Self-knowledge alone leaves you at even odds.
Win first, then fight
Chapter 4 says the victorious army wins first and then seeks battle; the defeated army fights first and then seeks victory. In other words, the outcome is decided by preparation, positioning and judgment before anyone moves. Good fighters first make themselves impossible to defeat, then wait for the enemy to become defeatable.
Deception
"All warfare is based on deception," chapter 1 says, in Giles's version. When able, seem unable; when near, seem far. This is about information, not dishonesty in everyday life: in a contest, don't hand the other side your plans.
Momentum and shape
Chapter 5 is about shi, the potential energy of a situation: a boulder rolled down a mountain, a crossbow drawn. The skilled general looks to the force of the situation rather than demanding too much of individuals. Chapter 6 adds that an army should be like water, which flows away from high ground toward low, and shapes itself to the land. Just as water has no constant shape, war has no constant conditions.
Speed and spies
Speed is "the essence of war," chapter 11 says. And the book closes (chapter 13) with a chapter on spies, arguing that the money spent on good intelligence is tiny compared to the cost of a war fought blind.
What their lines mean for you
At work. The Art of War is used in boardrooms for good reason. Win before you start: do the preparation that makes the meeting a formality. Attack the problem's plan, not its people. And count the cost of any long fight before you begin it.
In training. "Make yourself impossible to defeat first." That is the athlete's version of chapter 4: build the base, fix the weaknesses, then go looking for the win. The opponent's mistakes are not in your control. Your preparation is.
In grief. The book has nothing to say about grief, and that is worth noticing. It is a tool for one kind of problem. Not everything in life is a contest, and a person who treats every loss as a battle to win will exhaust himself.
In anger. Chapter 12 is blunt: a ruler should not raise an army out of anger, nor a general fight out of resentment. Anger can turn back to gladness, but a ruined state cannot be restored, nor the dead brought back to life. Few lines in any book give a better reason to wait before acting.
On the ocean. Chapter 6's water passage reads well to anyone who surfs. Water takes the shape of the ground; the army takes the shape of the enemy. You don't impose a plan on a swell. You read it and move with what it gives you.
With ambition. Sun Tzu's ambition is victory at the lowest price. Choose the battles you can win, avoid the ones you can't, and never mistake activity for progress.
Where people get them wrong
- "In the midst of chaos, there is also opportunity." Often credited to Sun Tzu. It is not in The Art of War. Chapter 5 does discuss order emerging from apparent disorder, but this sentence is modern.
- "Keep your friends close, and your enemies closer." Not Sun Tzu. It is from the film The Godfather Part II (1974).
- "Know your enemy." Usually quoted alone. The full passage puts self-knowledge on equal footing and warns that knowing only one side gives you a coin flip.
- The Art of War glorifies conflict. The book is closer to the opposite. It treats war as a disaster to be ended quickly or avoided entirely, and its highest praise goes to the general who wins with no battle at all.
- Sun Tzu certainly wrote it in the 6th century BC. The tradition says so; the evidence points to a later date and probably more than one author. That doesn't diminish the book.
