Abstract

Yi-yi extended his understanding of ‘a vast-flowing material force’ chapter to the institutional level of the nation as well as to the ethical level of the individual by faithfully reflecting and developing Zhu-xi's concepts of principle and mind. Song Si-yeol's interpretation of ‘a vast-flowing material force’ chapter is also basically an acceptance of Yi-yi's theory. However, he tried to expand a driving force for solving the problems of reality and a concept of denoting the identity of a school by highlighting more of the activism of the mind compared to Yi-yi. On the other hand, Yi-gan and Han Won-jin tried to limit the main concept of Yi-yi to the level of a concept of denoting the identity of a school. For example, Yi-gan and Han Won-jin are strongly critical of Song Si-yeol's understanding of inclination and material force as the structure of principle and material force. Their point is that inclination occurs because material force occurrs, but not principle. In this way, Song Si-yeol does not only deny the main concept of Yulgok School, but also threatens the concept of denoting the identity of a school, which is a flow from ChengZhu to Yulgok. Therefore, it is possible to conclude that the Yulgok School makes use of their interpretation of ‘a vast-flowing material force’ chapter in order to be an attempt to limit the concept of denoting the identity of a school.
