Huang Zongxi writes in his Mingru Xuean: "Among the students of Yangming, there were Wang Oen and Wang Ji, who made the greatest effort to advance Yangming's ideas. Yet they also had to be responsible for having failed to transmit their teacher's true doctrine." This view of Huang on Wang Gen and Wang Ji had long been revered by many Confucian scholars; as a result, the two Wangs were often treated like a pair of twin brothers ever since. This article challenges Huang's view by arguing that although Wang Gen and Wang Ji shared some philosophical ideas and together they had created a joint trend in their times, they were nonetheless quite different from each other in many ways. Their differences can be found not only in their philosophies, but also in their respective impacts on the development of Yaojiang School. In order to clarify some of the past misinterpretations of Wang Ji's philosophy, the author revisits the controversies of so-called "four forms of non-existence", and then tries to offer a new interpretation. In the author's view, Wang Ji's description of the Tianquan Bridge Meeting is far more correct than other versions; in addition, both Wang Ji's perspective and his arguments exhibit a philosophical depth that is unsurpassable by his peers. Huang Zhongxi's comment on Wang Ji is therefore incorrect; so is his interpretation of Wang Ji's ideas. In the end, the author suggests that if we adopt the viewpoint proclaimed by this article and use it to reexamine the development of Yaojiang School, we may hope to attain a fresh understanding and gain new insights into the history of Ming philosophy.
