This essay examined situation of Toegye Lee Hwang's
Documents Version of the Book of Changes which existed in
domestic and foreign with formal system as the center and
surveyed the fruition of studies about these. And then viewed
future orientation of research of Toegye's Yixue through this.
ChimengchunI and the Annotation of the Book of Changes in
Samkyungseokeu are writing composing the heart of Toegye's
Yixue. ChimengchunI and the Korean Annotation of the Book of
Changes in Samkyungseokeu are writing composing the heart of
Toegye's Yixue.
Edition of ChimengchunI and the Annotation of the Book of
Changes straggles at government and several science institution
such as the nation university library, the National Central Library,
the National Assembly Library, The Jangseogak Library of the
Academy of Korean Studies etc. Its concrete form and contents
examined in the light of book size, publication matter, special note,
paper nature and holding institution. ChimengchunI editions as the
heart literature of Toegye's Yixue thought are represented in
native and foreign several library with the very various aspect
according to publication area, period, publisher, holding institution,
paper nature, and the unique characteristics of respective edition.
The earlier studies of ChimengchunI was composed of various forms from translation involving comment and explanation to the
research regarding ChimengchunI as the establishment of
cosmological basis for Toegye's philosophy, one considering it
balancer of symbol & number and moral principle. Also, one paper
understood that ChimengchunI very well represents principle of
symbol-number theory through application of sound of Han
Dynasty symbol-number theory about five sound[五音] and six
melody[六律]. In sequence, research of the Annotation of the
Annotation of the Book of Changes was not only more later than
ChimengchunI about which translation and annotation was realized
in the early 1970s, but also research result of it was not
conspicuous.
The several researches of ChimengchunI and the Annotation of
the Book of Changes have respectively its own characteristics.
The several research papers of ChimengchunI partially made
reference to correlation with moral principle theory of I-Ching, but
mainly emphasized viewpoint and character of symbol-number
theory of it. Whereas several researches of ChimengchunI mostly
understood that this writing has characteristics of moral principle
theory of I-Ching.
What one must especially observe in the research of Toegye's
Yixue is that one understands symbol and moral principle in his
Yixue have any correlative meaning. In other words, it is the fact
that Toegye regards realm of necessity and oughtness being
involved between nature and man as unity of continual combination
by combining symbol with moral principle of I-Ching. Therefore
the future research direction of Toegye's Yixue must be that
researcher explores possibility of deepening research of Li-Chi
theory and mind-human nature theory and theory of practice of
Joseon Dynasty Neo-Confucianism through link context between
symbol and moral principle.
