Marxism found its highest historical expression in Bolshevism. Under the banner of Bolshevism the first victory of the proletariat was achieved and the first workers’ state established. No force can now erase these facts from history. But since the October Revolution has led to the present stage of the triumph of the bureaucracy, with its system of repression, plunder and falsification – the “dictatorship of the lie”, to use Schlamm’s happy expression – many formalistic and superficial minds jump to a summary conclusion: one cannot struggle against Stalinism without renouncing Bolshevism. Schlamm, as we already know, goes further: Bolshevism, which degenerated into Stalinism, itself grew out of Marxism; consequently one cannot fight Stalinism while remaining on the foundation of Marxism. There are others, less consistent but more numerous, who say on the contrary: “We must return Bolshevism to Marxism.” How? To what Marxism? Before Marxism became “bankrupt” in the form of Bolshevism it has already broken down in the form of social democracy, Does the slogan “Back to Marxism” then mean a leap over the periods of the Second and Third Internationals… to the First International? But it too broke down in its time. Thus in the last analysis it is a question of returning to the collected works of Marx and Engels. One can accomplish this historic leap without leaving one’s study and even without taking off one’s slippers. But how are we going to go from our classics (Marx died in 1883, Engels in 1895) to the tasks of a new epoch, omitting several decades of theoretical and political struggles, among them Bolshevism and the October revolution? None of those who propose to renounce Bolshevism as a historically bankrupt tendency has indicated any other course. So the question is reduced to the simple advice to study Capital. We can hardly object. But the Bolsheviks, too, studied Capital and not badly either. This did not however prevent the degeneration of the Soviet state and the staging of the Moscow trials. So what is to be done?
