Abstract
Two years ago, a professor at the University of California, Herbert Marcuse, an American social philosopher with traditional German training, came to be regarded as the recognized theoretician of the "New Left" movement. Marcuse's popularity compelled many writers, including ourselves , to make a careful examination specifically of the theoretical content of that teaching, which laid claim to performing the role of a critical and revolutionary theory of society. The development of a critique of the philosophical and theoretical foundations and the internal contradictions of Marcuse's teachings was thus dictated by a real situation, by the actual struggle of ideas, and has perhaps still not lost its significance. Another problem, which aroused the interest of researchers even then but which had not found an answer in our article because of its specific purpose, had to do with the relationship between Marcuse's philosophical concept and the spontaneous consciousness of the "mass" participants in the real protest movement that came to be known as the "New Left" movement
