Lenin's methods [of "hard" centralism and mistrust of the working class] lead to this: the party organization substitutes itself for the party, the central committee substitutes itself for the organization, and, finally, a "dictator" substitutes himself for the central committee. ... The party must seek the guarantee of its stability in its own base, in an active and self-reliant proletariat, and not in its top caucus ... which the revolution may suddenly sweep away with its wing.
