研究期間:10108~10207;Guan Dongming (Zhidao, 1537-1608) was a scholar and student Geng Tiantai (1524-1596) in Ming dynasty. Huang Zongxi thinks that he belongs to Taizhou school, and combines Confucianism as well as Buddhism in Mingru Xuean. Modern scholars regard him as an important person advocating the integration of Three Religions in late Ming. However, Yi is the foundation of his thought and the meaning of Qian Hexagram is the main aim in his works, Yice Liulongjie and Liulong Pouyi. In the meantime, there are still lots of discussions about Six Dragons in the other works by the disputes between their teacher and friends. His view of Qian is unique. There is no better or worse in Six Dragons because of no fixed frame. Confucius is regarded as Diving Dragon, King Wen as Flying Dragon, and Buddhism as Magic Dragon, which causes the question of his teacher, Geng. In fact, he thinks that Alerting Dragon , the most important one and able to take place of Showing as well as Flying Dragons, is the treatment of curing the disadvantages for Wang Yangming school in Taizhou. This view is the same with Ji Pengshan’s Longtishu. Guan’s theory of Qianyuan is no different from Huayan Xinghai. He makes combination of Three Religions, but doesn’t interfere with each discipline. To sum up, during the development of Mind philosophy in late Ming, his study of Yi could reflect the treatment of Wang Yangming school, and show the openness to negotiate with Buddhism as well as Daoism. It provides an important clue to study Yi Learning in Ming dynasty.
