    人君之欲平治天下而垂荣名者,必尊贤而下士。夫朝无贤人,犹鸿鹄之无羽翼也,虽有千里之望,犹不能其意之所欲至矣;是故江海者托于船,致远道者托于乘,欲霸王者托于贤。是故吕尚聘,而天下知商将亡,而周之王也;管夷吾、百里奚任,而天下知齐、秦之必霸也。纣用恶来,齐用苏秦,秦用赵高,而天下知其亡也。

    齐景公伐宋,至于岐堤之上,登高望,太息而叹曰:“昔我先君桓公,长毂八百乘以霸诸侯,今我长毂三千乘,而不敢久处于此者,岂其无管仲欤!”弦章对曰:“臣闻之,水广鱼大,君明则臣忠;昔有桓公,故有管仲;今桓公在此,则车下之臣尽管仲也。”

    杨因见赵简主曰:“臣居乡三逐,事君五去,闻君好士,故走来见。”简主闻之,绝食而叹,跽而行,左右进谏曰:“居乡三逐,是不容众也;事君五去,是不忠上也。今君有士见过人矣。”简主曰:“子不知也。夫美女者丑妇之仇也盛德之士乱世所疏也正直之行邪枉所憎也。”遂出见之,授以为相,而国大治。

    子路问于孔子曰:“治国何如?”孔子曰:“在于尊贤而贱不肖。”子路曰:“范中行氏尊贤而贱不肖,亡何也?”曰:“范中行氏尊贤而不能用也,不肖而不能去也;贤者知其不己用而怨之,不肖者知其贱己而雠之。贤者怨之,不肖者雠之;怨并前,中行氏虽欲无亡,得乎?”

    无常安之国,无恒治之民;得贤者则安昌,失之者则危亡,自古及今,未有不然者也。明镜所以昭形也,往古所以知今也。夫知恶往古之所以危亡,而不务袭迹于其所以安昌,则未有异乎却走而求逮前人也
