A Study on the Characteristics of Lee Ju-cheon’s Yijing Thought

This paper studied the characteristics of Lee Ju-cheon's thoughts through his writings. Lee Ju-cheon is a scholar of the Namin line, and his specific academic background is unknown. The content of his work is mainly related to Yijing, so it shows the core of his idea. Among his writings, Sinjeunghwang-geugnaepyeon can be cited as one of the representative studies on Hongbeomhwang-geugnaepyeon in Joseon. He made up for the shortcomings of existing research and made his own new attempts. He argued that mathematical principles and human values should be combined. He wrote under the title "Yielding[柔] is better than Firming[剛]" and he discussed the value of "Yielding" from a Confucian perspective, not from a Taoist perspective. He paid attention to the value of the Way of Earth and Yielding rather than to the Way of of Heaven and firm. It shows an aspect of the change in the ideological world in the late Joseon Dynasty.
