“[…] the dictatorship of the proletariat cannot be exercised through an organisation embracing the whole of that class, because in all capitalist countries (and not only over here, in one of the most backward) the proletariat is still so divided, so degraded, and so corrupted in parts (by imperialism in some countries) that an organisation taking in the whole proletariat cannot directly exercise proletarian dictatorship. It can be exercised only by a vanguard that has absorbed the revolutionary energy of the class. The whole is like an arrangement of cogwheels. Such is the basic mechanism of the dictatorship of the proletariat, and of the essentials of transition from capitalism to communism.”
Lenin continues:
“It is Trotsky who is in ‘ideological confusion’, because in this key question of the trade unions’ role, from the standpoint of transition from capitalism to communism, he has lost sight of the fact that we have here a complex arrangement of cogwheels which cannot be a simple one; for the dictatorship of the proletariat cannot be exercised by a mass proletarian organisation. It cannot work without a number of “transmission belts” running from the vanguard to the mass of the advanced class, and from the latter to the mass of the working people.”
