Wang Yangming, a prominent Neo-Confucian in the Ming Dynasty, had studied the Buddhism and Taoism too. After he came back to the Confucian camp and promulgated the teachings of ＂the heart is the principle,＂ ＂doing good conscience,＂ he raised also the view of ＂three teachings come from same origin＂. With this view he would be criticized as ＂to be a Confucian outsidely, but a Buddhist intrincically＂ by the late scholars. But the author holds that being a true Confucian must to take the responsibility for the world of culture, to establish the meaning of life and to carry forward the truth and wisdom of Confucian teachings, and as well as, holds that the modern Neo-Confucian must seriously recognize their historical place and take their responsibility for their great teachings. In this paper the author will discuss the relation between Wang Yangming and the Daoism and Buddhism firstly, and then to expose ＂how Wang fuse the teachings of Daoism and Buddhism through his theory of good conscience (liangzhi xue)＂, and, lastly, to explain the meaning and value of the discourse ＂three teachings come from same origin.＂ As conclusion, the author will hold that Wang Yangming can bring all teachings in confrontation with each other, can unify all things in one, because he has so firm a confidence for his teaching of ＂good conscience.＂ And with this I will to suggest, all must bear firmly in mind, at once man be situated in an extravagant, enstrangeous world.
