In its struggle for power the proletariat has no other weapon but organisation. Disunited by the rule of anarchic competition in the bourgeois world, ground down by forced labour for capital, constantly thrust back to the 'lower depths' of utter destitution, savagery, and degeneration, the proletariat can, and inevitably will become an invincible force only through its ideological unification on the principles of Marxism being reinforced by the material unity of organisation, which welds millions of toilers into an army of the working class.

Strikes, boycott, parliamentarism, meetings and demonstrations are all good forms of struggle as means for preparing and organising the proletariat. But not one of these means is capable of abolishing existing inequality. All these means must be concentrated in one principal and decisive means; the proletariat must rise and launch a determined attack upon the bourgeoisie in order to destroy capitalism to its foundations. This principal and decisive means is the socialist revolution.

Marxism is the science of the laws governing the development of nature and society, the science of the revolution of the oppressed and exploited masses, the science of the victory of socialism in all countries, the science of building communist society.

Leninism is Marxism of the era of imperialism and the proletarian revolution.

Until the bourgeoisie is completely vanquished, until its wealth has been confiscated, the proletariat must without fail possess a military force, it must without fail have its "proletarian guard," with the aid of which it will repel the counter-revolutionary attacks of the dying bourgeoisie, exactly as the Paris proletariat did during the Commune.

Undoubtedly, our path is not of the easiest; but, just as undoubtedly, we are not to be frightened by difficulties. Paraphrasing from the well-known words of Luther, Russia might say: 'Here I stand on the frontier between the old, capitalist world and the new, socialist world. Here on this frontier I unite the efforts of the proletarians of the West and of the peasantry of the East in order to shatter the old world. May the God of history be my aid!'
