《管子·法法》
君主发令而不能贯彻执行，是因为政令没有其合法性；合法性的政令不能贯彻执行，是因为起草政令不够慎重周密；慎重而不能贯彻，是因为赏罚太轻；赏罚重而不能贯彻，是因为赏罚还不信实；信实而不能贯彻，是因为君主不以身作则。
令而不行，则令不法也；法而不行，则修令者不审也；审而不行，则赏罚轻也；重而不行，则赏罚不信也；信而不行，则不以身先之也。
If the ruler makes orders and they cannot be thoroughly implemented, it is because the orders do not have their legitimacy; if legitimate orders cannot be thoroughly implemented, it is because the drafting was not cautious and thorough; if they are cautious but still cannot be thoroughly implemented, it is because the rewards and punishments are too light; if the rewards and punishments are heavy but still cannot be thoroughly implemented, it is because the rewards and punishments are not credible; if they are credible but still cannot be thoroughly implemented, it is because the ruler does not live by example.
