The paper includes three parts : part one raises the question , and put forward the western solution to the relation between science and technology and humanism by going back through western history of science and technology criticism . part two explores the cause of the two types of culture and the two types of science turning on parrel roads since modern times and the contemporary dilemma caused by the development of science and technology and ways to its solution - through historical reflection on the relation between science and technology and humanism . the last part puts forward " double stressing " on developing science and technology and upholding humanism 文章分三部分：第一部分，通过对西方科技批判思潮的历史梳理，提出问题并揭示西方哲学对科技与人文关系的理解及处理方式；第二部分，对科学技术与人文关系作了历史反思，探讨了近代以来两类文化、两类科学走上对立道路的原因以及科技发展带来的当代困境及脱困方式；第三部分，在前两部分的基础上，提出发展科学技术与弘扬人文精神并重。
