Weak Points And Strong

Chang Yu attempts to explain the sequence of chapters as follows: "Chapter IV, on Tactical Dispositions, treated of the offensive and the defensive; chapter V, on Energy, dealt with direct and indirect methods. The good general acquaints himself first with the theory of attack and defense, and then turns his attention to direct and indirect methods. He studies the art of varying and combining these two methods before proceeding to the subject of weak and strong points. For the use of direct or indirect methods arises out of attack and defense, and the perception of weak and strong points depends again on the above methods. Hence the present chapter comes immediately after the chapter on Energy."

Sunzi VI. 5.

Hence that general is skillful in attack whose opponent does not know what to defend; and he is skillful in defense whose opponent does not know what to attack.1

O divine art of subtlety and secrecy! Through you we learn to be invisible, through you inaudible;2 and hence we can hold the enemy's fate in our hands.

1. An aphorism which puts the whole art of war in a nutshell.

2. Literally, "without form or sound," but it is said of course with reference to the enemy.

Giles VI.8,9.

Le grand art d'un général est de faire en sorte que l'ennemi ignore toujours le lieu où il aura à combattre, et de lui dérober avec soin la connaissance des postes qu'il fait garder. S'il en vient à bout, et qu'il puisse cacher de même jusqu'aux moindres de ses démarches, ce n'est pas seulement un habile général, c'est un homme extraordinaire, c'est un prodige. Sans être vu, il voit ; il entend, sans être entendu ; il agit sans bruit et dispose comme il lui plaît du sort de ses ennemis.
