約當中國乾嘉前期之日本古文辭派學者龜井南冥（1743-1814），推崇中國三代古聖先王，不僅視《論語》為孔子義理的說明，更將六經視為是孔子觀全、祖述先王之道的實質展現。除此之外，又特別以《左傳》為標舉孔子學先王之道的具體所在。他將《左傳》視為孔門遺典，以其時代最近孔子，乃為解釋孔子之學的至要典籍。他主張排除孟子、漢儒、宋學對《春秋》的說解，多糾舉杜預注解，企圖透過語言文字與歷史事件的客觀索解，回歸《春秋》與《左傳》原始語境，以求趨近更為純然的孔子之學。此乃繼承古文辭學派荻生徂徠經學理念之再精進，並將之具體實踐在注解《左傳》上。本文試述其考究《左傳學》之脈絡，以見其在不同文化脈絡下、因異而新的思維，當其作為中國經學研究的他者，實具深究之價值。

Kamei Nammyeong, a Japanese scholar, highly emulates the ancient Chinese saint Kings, regarding The Analects as Confucius' theoretic works and the Six ClassicBook as records of ancient Saint Kings' great achievements. Since ZuoZhuan, or The Zuo Commentary on The Spring and Autumn Annals, was written in a time closest to Confucius', it was considered the most important book in the interpretation of Confucius' works. In his attempt to get to the purest Confucianism, Kamei Nammyeong traced back to the context of ZuoZhuan and the Spring and Autumn Annals, examining the wording and explanation of historical events while excluding the interpretation or annotation of the Spring and Autumn Annals by Mencius, Du-yu as well as scholars in the Hand and Sung Dynasty. This project will try to explore Nammyeong's work, Exegesis on ZuoZhuan and The Spring and Autumn Annals, focusing on the records on Duke Yin, Huan and Zhuang. In order to best understand Nammyeong's idea and practice of the interpretation of the Classic, it will analyze his explanation on the Exegesis on ZuoZhuan as reference materials. What is the essence of Confucianism? How can we best interpret Confucius' thoughts? Hopefully, this result of this study will prove helpful to modern Chinese studies on ancient Classics in the future.
