昔之善战者,先为不可胜,以待敌之可胜。不可胜在己,可胜在敌。
翻译:过去善于打仗的将领,首先做到自己不被敌人战胜,再等待时机战胜敌人。不被敌人战胜取决于自己做好准备、不犯错,是否能战胜敌人取决于敌人是否犯错。
The art challenges the technology, and the technology inspires the art.
The strongest is never strong enough to be always the master unless he transforms strength into right and obedience into duty.
