As a key figure in the unfolding of Yangming Learning in the late Ming, Wang Ji is generally regarded to be much closer to Chan Buddhism. But what on earth was the relation between Wang Ji and Buddhism? It seems this topic has been neglected in the scholarship community. This monograph first examines the communication between Wang Ji and some famous Buddhists, like Yuzhi Faju and Yunxi Zhuhong, and then analyses Wang Ji’s absorption of Buddhism and creative interpretation of some basic concepts of Buddhism, which is based on his Confucian standpoint. This monograph, which joins historical study and philosophical argument, probes in detail the relation between Wang Ji and Buddhism, points out the ontological difference between Confucianism and Buddhism, and provides a case study for the interaction between Confucianism, especially Yangming Learning and Buddhism in the late Ming.
