Abstract

In the field of history of Chinese philosophy, the key points and difficulties in the research on Fang Yizhi are mainly reflected in two ideological lines: one is how the academic pattern of the transition from Neo-Confucianism in the Song and Ming Dynasties to the texturalism in the Qing Dynasty happened; the other is how the traditional Chinese humanities accepted the western modern natural sciences and technologies. Relatively speaking, in the late Ming and early Qing Dynasties, there were fewer academic discussions on the relationship between intellectual thought and natural science and technology, and no universally accepted explanatory paradigm has been put forward yet. To understand the relationship between science and humanities in late Ming and early Qing Dynasty, as well as that between modern western natural science and ancient Chinese traditional thought, Fang Yizhi is a precious object of study. Fang Yizhi's thinking and practice about "things" is a bridge linking the natural world and the human world. “Thing” in Chinese philosophy has both concrete and abstract attributes, including but not limited to the category of “matter” in Western philosophy. Fang Yizhi has always been regarded as an encyclopedic thinker, and his theory of things is extremely rich. The theory and practice of things are the core of Fang Yizhi's philosophy. Fang Yizhi believes that the three religions all hold that the ultimate noumenon itself is "unknowable" and at the same time is the fundamental basis of every single thing, so people can only "study its origin" from the "knowable", that is, the "thing". This train of thought lies in the base of Fang’s thinking when describing and analyzing the relationship between Dao and things, which includes both theories of the universe and the ontology. This paper holds that the basic idea of Fang Yizhi's philosophy on the theory of body and function is that ‘there is no body but there is function’, while on the theory of universe it is that what above Yin and Yang are unknowable. Because the Dao has no body, it has only the function. And because nothing above the Yin and Yang can be understood, people can only use what is below the Yin and Yang such as the principle, qi 氣, image and number, to form the universal principle through the induction of the principle of “things”. Furthermore, Fang Yizhi ascribes the body, mind, nature and destiny to the concept of things, that is to say, he regards the self as the object of rational cognition. In this relationship, "I" is not only the subject of cognition, but also the object of cognition, thus realizing introspection inward. Thirdly, utensils and heaven and earth, that is, man-made objects and natural objects, are external to the self. Although Fang Yizhi also advocated "making" things external to human beings, under the social class system of scholars, peasants, workers and businessmen, he could only engage in the research of the theory of external things, that is, the so-called science of quality and measurement. On the whole, Fang Yizhi's physical research and practice did not go beyond the scope of Chinese traditional natural science, but he was good at summarizing research methods, actively absorbing the contents of western natural science, and put forward correct ideas on many specific natural science issues. Mou Zongsan's discussion on the relationship between existence and activity inspires the author to think about the significance of the theory of “round ∴”. Fang Yizhi drew a series of laws represented by the theory of “round∴” through the induction of the principle of being. Although these laws are derived from existing things, they themselves are not static, but show two levels of active states: one is the internal dynamics of the laws, that is, the constant rotation; the other is that the law derived from the existing things can be applied to the activities of people, considering eternity and change, the right timing and other variable factors. This paper tries to follow the essence of Fang Yizhi's thought to seek for communication and connection between objects and things, between being and activity, between natural science and moral and human ethics. From the perspective of the development of modern and contemporary Chinese philosophy, the study of mind has always occupied an important position, and the corresponding philosophical research of “things” is relatively lacking. In theory, mind and thing are relative and inseparable aspects, and the thoughts on “things” in traditional Chinese thought resources are comparable to the study of mind in terms of diachronic, textual volume and theoretical depth. The rapid development of modern natural science and technology and its challenges to the human world have promoted the deep and lasting reflecting on the problem of things and the relationship between people and things in western philosophy. Scientific rationality invades every aspect of human's life. The transformation of knowledge to practical technology enhances human's ability to control and transform things. Instrumental rationality dominates human's understanding of things, and “things” fall from the meaning world of human's living situation and become the means to meet human's needs. A re-examination of this period in Chinese history, when pre-modern ideas and science and technology first collided, may be helpful to enlighten us to think about the relationship between science and technology and the world of human significance.
