This chapter summarizes the findings on theoretical frameworks of comparative legal history to pave the way for future research. We will first summarize the concepts of “rule-based law” and “public opinion-oriented law” and their connection to the respective social images. We will then explore the significant differences between “rule-based law” and “public opinion-oriented law” in the role of written laws, the relationship between social regularity and public authority, and the nature of contract society. Finally, we will propose two exciting research directions: Exploring forms of law beyond those presented in this book and further examining the relationship between traditional law and Modern Law. They offer ample opportunities for future scholarly exploration.
