Abstract: Marcuse points out that science and technology promote productivity, meanwhile penetrating the ideological field and being ideological in his book One-Dimensional Man. After ideologicalization, science and technology are more hidden to the person’s rule and control, which leads to the working class losing revolution subject consciousness and the political discourse of people tending to be closed. Marcuse’s critical thought of science and technology plays an important role to grasp the technological rationality and humanistic rational coordination, preventing the alienation of science and technology, reflecting the relationship between human, nature and society, and constructing harmonious ecology.
