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

敵雖衆可使無鬥故策之而知得失之計

Though the enemy be stronger in numbers, we may prevent him from fighting.

Scheme so as to discover his plans and the likelihood of their success.

Lionel Giles's notes

Capt. Calthrop quite unwarrantably translates: “If the enemy be many in number, prevent him,” etc.

This is the first of four similarly constructed sentences, all of which present decided difficulties. Chang Yü explains 知得失之計 as 知其計之得失. This is perhaps the best way of taking the words, though Chia Lin, referring 計 to ourselves and not the enemy, offers the alternative of 我得彼失之計皆先知也 “Know beforehand all plans conducive to our success and to the enemy’s failure.”
