With extensive research and creative interpretations, Dasan’s Noneo gogeum ju (Old and New Commentaries of the Analects) has been evaluated in the academia of Korean Studies as a crystallization of his studies on the Confucian classics. Dasan (Jeong Yak-yong: 1762-1836) attempted through this book to synthesize and overcome the lengthy scholarly tradition of the classical studies of the Analects, leading it not only to represent one of the greatest achievements of Korean Confucianism but also demonstrate an innovative prospect for the progress of Confucian philosophy, positioning it as one of the ground-breaking works in all Confucian legacies in East Asia. Originally consisting of forty volumes in traditional book binding, his Noneo gogeum ju contains one hundred and seventy-five new interpretations on the Analects, hundreds of arguments about the original meanings of the Analects commentaries, hundreds of references to the scholarly works of the Analects, thousands of supportive quotations from various East Asian classics for the author’s arguments, and hundreds of philological discussions. This book is the second volume of an English translation of Noneo gogeum ju with the translator’s comments on the innovative ideas and interpretations of Dasan on the Analects.
