Whether in China or in the West, when philosophy first appeared, it was based on materials, such as vitality, water, fire, earth and so on. Later, people found that there were many unexplained things in the world, so they added metaphysical things, that is, objects at the level of consciousness, such as Rogers, Tao, ideas and so on. In this way, the matter that begins in the first sex becomes the second sex after consciousness.

However, with the development of productivity and science and technology, people pay more attention to experience and achievements. Thus, another subversion occurred in the history of philosophy. Philosophers have shifted from the relationship between matter and consciousness to the relationship between experience and theory.

Finally, thousands of years later, the concept of material first and consciousness second was widely recognized by the public.
