520 __ |a The unfinished masterpiece of Friedrich Engels, a German philosopher, is a summary of Engels' long-term research on natural science. In this, he systematically expounded the dialectics of nature for the first time, promoting a profound change in the concept of nature; he explored the philosophical issues of natural science in depth, the integration of philosophy and natural science; and provided theoretical tools such as dialectical materialism epistemology, methodology, and dialectical logic for scientific research. "The Dectics of Nature" is not only a philosophical reflection on the laws of change in nature, but also a profound exposition of the dialectical unity of man and nature. A study of this work is of great significance for us to understand the concept of harmonious coexistence between man and nature in the contemporary context.
