Abstract: The ideology of capitalist technological rationality is the kernel of Marcuses ideology theory. In his view， technological rationality penetrated into every aspect of social life in the developed capitalist society; moreover， it took on a greater control because of its super-class and non-political veil. Based on an explanation of the ideologicalization of scientific and technological rationality and an analysis of “false needs” and “additional depression”， he revealed the reason why people in the capitalist society were “unidimensional”. In view of the “unidimensional person” of technological rationality， Marcuse proposed the idea of transcending the science and technology ideology of the developed capitalist society， namely， realizing “the new socialism” via “the overall revolution”.

Key words: Herbert Marcuse, ideology, technological rationality
