On the basis of inheriting the school's "dedication" and "conscience" and Lu Jiuyuan's "mind is reason" theory, he critically absorbed Zhu's transcendental category of "transcendental reality" as ontology and founded the theory of mind. Wang Xue's internal structure is composed of conscience and conscience through the integration of knowledge and action. In this structure, Wang Shouren speaks with his heart (conscience) and explains it with his conscience. Heart (conscience) is the cornerstone of Wang Xue. In Wang Shouren's view, the heart is all-encompassing. Things, things, reason, righteousness, goodness and learning are all outside of "my mind", that is, "mind is reason". However, he also believes that "conscience" is the noumenon of the mind and is the innate, transcendental and universal "knowledge" of human beings. This kind of "knowledge" is the nature of knowing without worrying, and it is the inherent possibility of "conscience" and sanctification. At the same time, he emphasized that "conscience" is the unity of external social ethics and internal individual psychological desire ("justice lies in people's hearts"), which is the same as everything in the world. It is this "conscience" that fills heaven and earth that makes "I" and everything (including society) circulate in one breath, blending with each other without interval. It is this lively "conscience" and "Zhong Ni is in everyone's heart" that inspire people to pursue that kind of "phoenix flies thousands of miles" and "moral purity", which greatly emphasizes the initiative of subjective consciousness, holds high the greatness of personality spirit, and becomes the inherent requirement of the subject's efforts the day after tomorrow. Here, it breaks through the absoluteness of Zhu's "natural justice", thus affirming the rationality of human desire.
