Abstract: There have always been different opinions on if Science has positive function or negative. This paper, based on analysing the critic attitude to science of some Chinese intellectuals especially the intellectuals studying the humanities since the last century, restates that science can give people reason and strength, self-respect and self-confident, and that science is the backing of humanity not its enemy. Therefore, the paper lays stress on the important significance of understanding the spirit, quality and involved range of science, and taking scientific attitude towards science.
