【Abstract】 In his theory, Habermas revealed the quintessence of scientific and technological changes, pointing out the dual functions of science and technology in the advanced capitalistic states. He deduced that in later period of capitalism, technology and science become“a leading productive force”, and at the same time, they also act “as a background ideology”. He drew a conclusion that the interdependence of science and technology as well as the state intervention into research were two prerequisites to these dual functions. The interdependence made science and technology into an organic whole, and the state intervention made them into a real leading productive force. Thus these two factors together let science and technology perform a kind of ideological function.更多还原
