《智囊(选录)·上智部·孔子》
于是孔子改派马夫前去要马，马夫对农夫说： 你从未离家到东海边去耕作，我也不曾到过西方来，但两地的庄稼却长得一模一样，马儿怎么知道那是你的庄稼而不能偷吃呢？ 
乃使马圉往，谓野人曰： 子不耕于东海，予不游西海也，吾马安得不犯子之稼？ 
So Confucius sent the groom to retrieve the horse, and the groom said to the farmer: You have never left home to farm on the coast of the East China Sea, and I have never travelled west, but the crops in both places grow exactly the same. How would the horse know that those crops were yours and refrain from eating them?
