This paper is on the relationship between the laws of science and the laws of nature as well as on the limitations of science in terms of the modifications about scientific cognition in history. Historically, humanism and science used to be harmonious; yet the magnificent development of scientism and technolatry put human civilization into a crisis, which is also true to Chinese culture. Chinese culture tries to learn science and technology with a practical state of mind without the spirit of science. Scientism and technolatry throw humanistic spirit to the edge of destruction and put therefore human civilization into a crisis, since a well-integrated life must assimilate science, technology and humanism.
