주역 九卦의 義理에 관한 육구연의 논변과 그 尊德性

Abstract

The essay is focused upon presenting how Jiu-yuan Lu can understand the implicative significance of the Nine Gua described three times in the Commentaries on the Book of Changes. In the Neo-confucian context of self-realization and its practice, his academic learning depends upon the human character of respecting the virtues which establish the autonomy of subject in the inner virtues. The human character of respecting the virtues includes the canon of cultivation. It is representative as the motto that heart-mind is principle, which is a kind of endeavor to guarantee the universal value of justice and righteous way. For concretizing it, he regards a series basic position as the practice, the modesty, and the restoration hexagram, a series of applying rule as the constancy, the loss, and the benefit hexagram, and a series of extending way as the difficulty, the flow, and the courtesy hexagram. It seems to me that his understanding is so identical with the heart-mind theory that "one deserves one's heart-mind and explicates the principle." Consequently, it established an ethical basis for his doctrine of the original substance of heart-mind, which is oriented toward the ultimate stage of the Way of Learning.
