The Art of War (孫子兵法), Weak Points And Strong 虛實篇

故形人而我無形則我專而敵分

By discovering the enemy’s dispositions and remaining invisible ourselves, we can keep our forces concentrated, while the enemy’s must be divided.

Lionel Giles's notes

The conclusion is perhaps not very obvious, but Chang Yü (after Mei Yao-ch‘ên) rightly explains it thus: “If the enemy’s dispositions are visible, we can make for him in one body; whereas, our own dispositions being kept secret, the enemy will be obliged to divide his forces in order to guard against attack from every quarter.” 形 is here used as an active verb: “to make to appear.” See IV, note on heading. Capt. Calthrop’s “making feints” is quite wrong.
