《韩非子·人主》
所以，做君主的如果不能排除大臣的议论，摒弃左右的诬告，独自作出符合原则的判断，那么法术之士哪能冒死亡的危险而向君主进说呢？
故君人者非能退大臣之议，而背左右之讼，独合乎道言也，则法术之士安能蒙死亡之危而进说乎？
Therefore, if a monarch could not rule out officials’ arguments, dismiss slanders from close confidants, and make impartial judgments on his own, how could law and technique experts dare to risk their lives to give advice to the monarch?
