《韩非子·八经》
人之常情，有喜好和厌恶两种趋性，因而赏和罚可据以使用；赏和罚可据以使用，法令就可据以建立起来，治国政策也就进而完备了。
人情者，有好恶，故赏罚可用；赏罚可用，则禁令可立而治道具矣。
Human nature has two tendencies, likes and dislikes, so rewards and punishments can be used accordingly. Rewards and punishments can be used accordingly, laws can be established, and policies for governing the country can be further improved.
