It is commonly agreed by scholars studying Saneatsu Mushanokoji that Mushanokoji’s thinking is deeply affected by Tolstoy, Maeterlinck, Rodin and Whitman. However, some scholars declare that his thinking is characterized by eastern philosophy in the middle-late period of his life. I think this tendency has close relevance to his reading and writing of Eastern saints’ and philosophers’ biographical books in the late Taishou era and the early Showa era. The late Taishou era sees the rise of the proletarian literature and Mushanokoji starts to study and write about some heroic figures in both Western and Eastern countries because he wants to present his personal ideas in his works and survive the competitive literary world. He has published more than 10 articles on Confucius and Analects in the late Taishou era and the early Showa era, and the two articles entitled “Personal Comments on Analects” and “Confucius” are published without being compiled into books. In these articles, he reveals much admiration for Confucius’s philosophy and for the famous sayings extracted from Analects. Furthermore, he highlights some personal viewpoints in his works with the supportive quotations from Analects. This article aims to discuss the similarities and differences between Confucius’ and Mushanokoji’s thinking and ideas since Mushanokoji is greatly affected by Confucianist thinking. In addition to the preface and conclusion, this article consists of five sections as follows: 1.Confucianist education received in the teenager period 2.Changes in thinking due to Mushanokoji’s admiration for and influence by the Western saints’ and philosophers’ great philosophy in his teenager period 3.A re-study of Analects in writing biographical novels 4.The significant features in Mushanokoji’s articles about Confucius and Analects 5.Mushanokoji’s approvals and disapprovals of specific sayings extracted from Analects
