The text is divided into six parts. The introduction introduces the connotation and contemporary significance of natural philosophy, explains the significance and value of the study of mohism from the perspective of natural philosophy, and reviews the present situation of mohism. The first chapter discusses the concept of the nature way of the Moi family, which was developed on the basis of Yin Shang and the Western Zhou dynasty. The Moi family formed its own thought of the nature way by reforming the concept of "nature" and constructing the concept of "law". The second chapter discusses the natural knowledge of the Mo family, including cosmology and specific natural knowledge. In cosmology, the Mohist objectified and empirically reconstructed the cosmic picture. In the specific aspects of natural knowledge, the Mohist developed the knowledge tradition of preQin craftsmen, and made important achievements in geometry, mechanics and optics, which gave birth to a new type of knowledge. The third chapter discusses epistemology and methodology in the natural philosophy of the Mohist. The Mohist insists on the knowability of the world. There are observation and experiment, classification, concept definition and logical reasoning in the natural philosophy of Mohism. The differences between the Moist logic and the Aristotle logic are explained from three aspects. The fourth chapter discusses the cultural fate of the Mohist natural philosophy in later times. The natural philosophy of the Mo family had a profound influence on Xunzi of the Pre-Qin Confucianism, Chuang Tzu of Taoism, Huishi of the famous and Gong Sun Long, and Han Fei of the French family. However, after the "unique respect for Confucianism", murology became heresy and basically disappeared in the mainstream culture. It was only in modern times, under the background of national peril and the introduction of Western studies, that the Mohist natural philosophy was discovered, studied and spread. Chapter five discusses the contemporary value of Mohist natural philosophy. Mohist natural philosophy contains rich scientific spirit, artisan spirit and science and technology ethical thought, which is of great value to the development of science and technology in our country.
