Juedi Tiantong: The Religious Basis of the Relationship between Tian and Man in Ancient China

Juedi Tiantong occurred in ancient China and was the critical foundation for understanding the relationship between Tian and man in China. From the perspective of conceptual history, Juedi Tiantong not only shaped the metaphysical dimension of the concept of Tian, but also transformed the original religious form of communication between man and natural gods into the unity of human nature and Tiandao, which liberated the relationship between Tian and man from the religious field. Therefore, Juedi Tiantong should be regarded as the critical basis of the unity of heaven and man in Chinese philosophy. Furthermore, as an important religious revolution, Juedi Tiantong also affected people’s understanding of nature, which was mainly reflected in the recognition of astronomy and calendar reform. In ancient China, it was difficult to distinguish between humanity and astronomy, science and religion, and rationality and divinity. In this case, Juedi Tiantong also abstracted Tian, originally representing the physical sky, into a metaphysical concept. Accordingly, the concept of Tian in Chinese philosophy has not developed the same meaning of nature as Western civilization.
