The aim of this thesis is to study on the Kim Ji-Ha's aesthetic thought. Kim Ji-Ha is a poet. But it seems to me that he is an excellent thoughter. Kim' aesthetic thought based on the Korean Dong-Hak thought. The main concept of Dong-hak thought is a Mosim(Care). Kim Ji-Ha starts from this Mosim concept. This Mosim is not only a respect but also and horizontal friendship. The true Mosim is a respect at a distance. This distance is the space of a freedom and autonomy. According to Kim the concept of Mosim in Donhak's philosophical system implies radical egalitarianism, yet, at the same time, it presupposes the distance between the individuals. In other words, Donhak's egalitarianism always incorporates ethical admiration of orthers in terms of mutual friendshilp ecological love and high regard. According of Kim Ji-Ha, today we must look for the new middle tone. That tone must be not only Yang but also Yin. The universe is both cosmos and chaos, chaosmos. But the middle point is placed in the Yin. The important concept in Kim's aesthetic thought is 'Teum', which means space, room, distance, crevice, gap of mutual existence. And Kim JI-Ha suggests the aesthetics of shadow and white shadow, ring. According to Kim the mysterious shadow is not a mere dark shadow. The mysterious state of shadow is produced by the co-existence of paradoxical situation ― light and darkness, sorrow and joy. This lies between the Haeven and the mundane world, life and death, fantasy and reality, supenatural and sensuous experience, sameness and otherness. And white shadow signifies the of eternal cosmic life. In short, the white shadow is a shining and glowing one. At last, Kim suggests the aesthetics of ring. Ring is circular extention, expansion. And this ring comes out from collective joyousness.
