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. 15.

In making tactical dispositions, the highest pitch you can attain is to conceal them;1 conceal your dispositions, and you will be safe from the prying of the subtlest spies, from the machinations of the wisest brains.2

1. The piquancy of the paradox evaporates in translation. Concealment is perhaps not so much actual invisibility (see supra ss. 9) as "showing no sign" of what you mean to do, of the plans that are formed in your brain.

2. Tu Mu explains: "Though the enemy may have clever and capable officers, they will not be able to lay any plans against us."

Giles VI.25.

V. La suprême tactique consiste à disposer ses troupes sans forme apparente ; alors les espions les plus pénétrants ne peuvent fureter et les sages ne peuvent établir des plans contre vous.
