Confucianism, the core idea in Chinese culture, has existed in the mind and spirits of most intellectuals. This idea was also a fundamental moral value in the past political and legal systems. Therefore understanding “Confucian Ideology” is a keystone for those who desire to understand the course of change and evolution in legal systems. In contrast to the modern legal system, which is based on the rule of law and democracy, the traditional legal system, which is based on the Confucian ethics, is considered to be adequate for modern society. Confucianism seems to be deficient in the perspective of freedom and human rights. Most scholars are able to explain the reason why Confucianism was reasonable and legitimate in the past but they rarely connect itself with the contemporary legal thoughts. Seldom do they explore the internal rationales of Confucianism in the perspectives of modern legal thoughts. This gap opens a question of whether the Confucian legal thought is significant in modern society. In order to respond to this question, this article takes the idea of “priority of norms” in Confucianism as its main objective. First, this article analyzes the nature of “law” and illustrates its meaning by treating the foundation of law as a general consent in a group. And under this definition, this article claims that it is possible to treat “Li” (禮) in Confucianism as the same as “Law” (法) in the modern meaning. Therfore “Li” and “Law” are not supposed to be mutually excluded. Secondly, this article examines various arguments involving the idea of the priority of norms in Confucian, Mencious, and Xun Sanzi’s thoughts. This examination will also reflect on Confucianism and its humanitarian rationalism and modernity. Thirdly, this article will respond to some common challenges on Confucianism and will re-interpret some ideas in Confucianism, such as “straight bow case,” “peach responding to difficult questions,” and “rule by man, not by law.” By using this three-step approach, this article wishes to establish a structure and to contribute to the modern meanings of Confucianism.
