《庄子·外篇·天道》
赏罚明确因而愚钝与聪颖的人都能相处合宜，尊贵和卑贱的人也都能各安其位；仁慈贤能和不良的人也才能都袭用真情。
赏罚已明而愚知处宜，贵贱履位，仁贤不肖袭情。
Rewards and punishments must be clearly defined, so that fools and wise people can behave suitably, and the noble and humble can all keep their places. In this way, goodness and ability, or wickedness, will all come forth naturally.
