Abstract

For any inquiry into Tasan 's philosophy, it is absolutely necessary to investigate its relationship with Neo-Confucianism. Out of the many notions of his philosophy, the Kung-fu theory is considered to be important. Therefore, the comparison between Chu-hui 's system of Neo-Confucianism and Tasan's theory on Kung-fu is expected to offer clues that help us understand Tasan's philosophy. The purpose of this paper is to investigate Tasan’s viewpoints on the notion of ‘having not yet arisen,’ especially in regards to his issues of 'the mind, intelligence, consideration, and discretion ,' as presented in his Kung-fu theory. Tasan insists that the statement that "The joy, anger, sorrow, and pleasure have not yet arisen." differs from the statement that "The mind, intelligence, consideration, and discretion have not yet arisen." In this paper, the author will inquire into Tasan's assertions on the meaning, contents, subject, and significance of ‘the mind, intelligence, consideration, and discretion,’ which he emphasizes. In addition, the author will make clear that the above assertion is related to the following: 1) Tasan’s recognition of Cheon , 2) his assertion on the capability of the mind to make decisions by itself , and 3) his emphasis on the actualization of morality
