|Through the analysis of the essential meaning of “Tien” (Heaven) this paper tries to show that Tien-jen-chic-pien is an ethical proposition. Different philosophers appreciate different aspects of the meaning of “Tien,” but they never talk about the way of Tien as an isolated subject. Instead, they relate the way of Tien to the Way of “Jen” (Mankind). The discussion about the way of Tien is to demonstrate the rationality of the way of Jen and in turn construct moral theology or moral metaphysics. Therefore, that relation between mankind and nature should be within the range of Tien-jen-chic-pien is seriously ignored, and as a consequence, the claims of Qun Tzu's (荀子) school have not been developed. In this way, this paper argues that the recently popular ecological understanding of Tien-jen-chic-pien does not consist with what the ancient philosophers had in mind.
