《淮南子·主术训》
所以不 仁 却勇武有力、果断敢为，就会像疯子握利剑一样，后果难测；没有 大智 却能言善辩、机敏乖巧，就会像骑着骏马驰骋而漫无目标。
故不仁而有勇力果敢，则狂而操利剑；不智而辩慧怀给，则弃骥而不式。
Therefore, being unbenevolent but brave and resolute will be like a madman wielding a sharp sword—the consequences are unpredictable; being unintelligent but eloquent and resourceful will be like riding a fast horse without a destination.
