"Here we see the possible significance of Lenin's book for the future working-class movement. The Communist Party, though it may lose ground among the workers, tries to form with the socialists and the intellectual class a united front, ready at the first major crisis of capitalism to take in its hands the power over and against the workers. Leninism and its philosophical textbook then will serve, under the name of Marxism, to overawe the workers and to impose upon the intellectuals, as the leading system of thought by which the reactionary spiritual powers are beaten, Thus the fighting working class, basing itself upon Marxism, will find Lenin's philosophical work a stumbling-block in its way, as the theory of a class that tries to perpetuate its serfdom."
