《韩非子·二柄》
君主有两种祸患：任用贤人，臣下就会依仗贤能的名声来威逼君主；随便任用举荐的人才，就会事情就会败坏不成功。
人主有二患：任贤，则臣将乘于贤以劫其君；妄举，则事沮不胜。
There are two evils for a sovereign:--to employ men of worth, and then to entrust them with authority to the full extent of their virtue; and to employ men without inquiring into their worth, and to entrust them with authority to the full extent of their ability.
