This paper has a comparative analysis of natural law and Daoist law, focusing on the connections of law and morality. There is a description of the definitions of them and the historical analysis of natural law. And the stoicism is introduced to reveal the feature and nature of links of law and morality, which is supported with the current cases of violences worldwide to demonstrate the significance of moral rules, the states of mind. The Daoist law in China emphasizes the spontaneity of the inner world, a higher spiritual condition to be pursued in ancient China, free from the inappropriate desires, less intervention of the authority with more initiative of the general public. The western individualistic god-centered law under the guidance of reason and rationality can go well along with the collectivistic China’s Daoist law, the former stressed on the principles of justice, equality, fairness, etc. and the latter themed Ziran, self so, keeping as they are. The fighting guys of natural law and positive law in the West are mirrored with the counterparts of Daofa, the spontaneity of all things, and Lifa, the rule-based Confucian governance in China. The two couples as well as the two differing views within can either oppose or complement each other. Natural law can refer to the just doctrines, the moral principles, immanent in nature, while Daoist foundation is based on nature-like inclination, the self-so and other-so spontaneity.
