For a long time, scholars viewed the relationship between virtue and law from the perspective of dichotomy, or viewed the nature of ancient Chinese “law is punishment.” Based on the proposition that virtue and law complement and harmonize with each other by pre-Qin Confucians, contemporary scholars propose the integration of virtue and law and the concept of “virtuous rule of law.” From the perspective of historical development, law is a governance tool adapted to the complexity of society and the need to enrich the country and strengthen the army. From the logic of the development of political thoughts, law is a proposition to realize “impartiality” and oppose “partiality,” which has the spiritual essence of universality, objectivity, and impartiality. According to Xunzi, law is a system of love based on justice and principles; ritual rules have not only the function of social norms, but also the function of moral education. The aim of law, established, deliberated, and practiced by persons of character, is to achieve a kingly virtue-centered society full of rite, music, justice, order, harmony, and happiness. In Xunzi’s political philosophy, the idea of “virtuous rule of law” is finally realized.
