In terms of the concept of nature, Wang Chong emphasized the idea of "heaven and nature", believing that the operation and change of nature are determined by its own laws, and have nothing to do with the will of gods and human beings. He opposed the prevalent doctrine of Manifest Destiny and theism at the time, arguing that these theories could not explain the nature and changes of natural phenomena. At the same time, he also opposed the theory of yin and yang and the five elements, which was popular at the time, believing that this doctrine was too mysterious and mysterious to prove its authenticity. Wang Chong's view of nature emphasizes the objectivity and regularity of the natural world, and this kind of thinking still has an enlightening effect on our knowledge and understanding of the natural world today.

He argues that Confucianism places too much emphasis on tradition and authority and ignores the importance of facts and evidence. At the same time, he also opposed the Taoist ideas that were popular at the time, believing that such ideas were too negative and evasive to have a positive impact on society. He advocated the use of facts and evidence to test the rationality of moral and social systems, and believed that only moral and social systems that conform to facts and evidence are reasonable. This kind of thinking emphasizes the importance of facts and evidence, which still have implications for our knowledge and understanding of social problems today.
