孫子曰﹕
昔之善戰者,先為不可勝,以待敵之可勝。不可勝在己,可勝在敵。
故善戰者,能為不可勝,不能使敵必可勝。
故曰﹕勝可知,而不可為。
不可勝者,守也﹔
可勝者,攻也。
守則不足,攻則有餘。
善守者,藏於九地之下﹔
善攻者,動於九天之上。
故能自保而全勝也。
見勝不過眾人之所知,非善之善者也﹔
戰勝而天下曰善,非善之善者也。
故舉秋毫不為多力,見日月不為明目,聞雷霆不為聰耳。
古之所謂善戰者,勝於易勝者也。
故善戰之勝也,無智名,無勇功。故其戰勝不忒。不忒者,其所措必勝,勝已敗者也。
故善戰者,先立於不敗之地,而不失敵之敗也。
是故勝兵先勝而後求戰,敗兵先戰而後求勝。
善用兵者,修道而保法,故能為勝敗之政。
兵法﹕一曰度,二曰量,三曰數,四曰稱,五曰勝。
地生度,度生量,量生數,數生稱,稱生勝。
故勝兵若以鎰稱銖,敗兵若以銖稱鎰。
勝者之戰,若決積水於千仞之谿者,形也。

`Would you tell me, please, which way I ought to go from here?'
`That depends a good deal on where you want to get to,' said the Cat.
`I don't much care where--' said Alice.
`Then it doesn't matter which way you go,' said the Cat.
`--so long as I get somewhere,' Alice added as an explanation.
`Oh, you're sure to do that,' said the Cat, `if you only walk long enough.'
