The “lefts” who tried to skip Bolshevism in their return to Marxism generally confined themselves to isolated panaceas: boycott of parliament, creation of “genuine” Soviets. All this could still seem extremely profound in the heat of the first days after the war. But now, in the light of most recent experience, such “infantile diseases” have no longer even the interest of a curiosity. The Dutchmen Gorter and Pannekoek, the German “Spartakists”, the Italian Bordigists, showed their independence from Bolshevism only by artificially inflating one of its features and opposing it to the rest. But nothing has remained either in practice or in theory of these “left” tendencies: an indirect but important proof that Bolshevism is the only possible form of Marxism for this epoch.

The Bolshevik party has shown in action a combination of the highest revolutionary audacity and political realism. It established for the first time the correspondence between the vanguard and the class which alone is capable of securing victory. It has proved by experience that the alliance between the proletariat and the oppressed masses of the rural and urban petit bourgeoisie is possible only through the political overthrow of the traditional petit-bourgeois parties. The Bolshevik party has shown the entire world how to carry out armed insurrection and the seizure of power. Those who propose the abstraction of the Soviets from the party dictatorship should understand that only thanks to the party dictatorship were the Soviets able to lift themselves out of the mud of reformism and attain the state form of the proletariat. The Bolshevik party achieved in the civil war the correct combination of military art and Marxist politics. Even if the Stalinist bureaucracy should succeed in destroying the economic foundations of the new society, the experience of planned economy under the leadership of the Bolshevik party will have entered history for all time as one of the greatest teachings of mankind. This can be ignored only by sectarians who, offended by the bruises they have received, turn their backs on the process of history.

But this is not all. The Bolshevik party was able to carry on its magnificent “practical” work only because it illuminated all its steps with theory. Bolshevism did not create this theory: it was furnished by Marxism. But Marxism is a theory of movement, not of stagnation. Only events on such a tremendous historical scale could enrich the theory itself. Bolshevism brought an invaluable contribution to Marxism in its analysis of the imperialist epoch as an epoch of wars and revolutions; of bourgeois democracy in the era of decaying capitalism; of the correlation between the general strike and the insurrection; of the role of the party, Soviets and trade unions in the period of proletarian revolution; in its theory of the Soviet state, of the economy of transition, of fascism and Bonapartism in the epoch of capitalist decline; finally in its analysis of the degeneration of the Bolshevik party itself and of the Soviet state. Let any other tendency be named that has added anything essential to the conclusions and generalisations of Bolshevism. Theoretically and politically Vandervilde, De Brouckere, Hilferding, Otto Bauer, Leon Blum, Zyromski, not to mention Major Attlee and Norman Thomas, live on the tattered leftovers of the past. The degeneration of the Comintern is most crudely expressed by the fact that it has dropped to the theoretical level of the Second International. All the varieties of intermediary groups (Independent Labour Party of Great Britain, POUM and their like) adapt every week new haphazard fragments of Marx and Lenin to their current needs. Workers can learn nothing from these people.

Only the founders of the Fourth International, who have made their own the whole tradition of Marx and Lenin, take a serious attitude towards theory. Philistines may jeer that 20 years after the October victory the revolutionaries are again thrown back to modest propagandist preparation. The big capitalists are, in this question as in many others, far more penetrating than the petit bourgeois who imagine themselves “socialists” or “communists”. It is no accident that the subject of the Fourth International does not leave the columns of the world press. The burning historical need for revolutionary leadership promises to the Fourth International an exceptionally rapid tempo of growth. The greatest guarantee of its further success lies in the fact that it has not arisen away from the great historical road, but has organically grown out of Bolshevism.
