The working class movement is one of the oldest in the world. It has continued against all obstacles to fight for its emancipation and for a socialist society. Today its consciousness is growing about the necessity of challenging the type of society which exists in capitalist countries. It stands on the threshold of providing itself with modern class consciousness, which is to say the necessary consciousness to lead society out of the crisis, the consciousness of developing its own revolutionary theory from the concrete conditions as prevailing nationally and internationally by using Marxism-Leninism as a guide. In this regard the necessary instrument for the working class providing itself with a revolutionary theory is the proletarian party, the party of a new type, the vanguard of the working class. Without such a revolutionary theory, there can be no revolutionary working class movement aimed at the overthrow of the capitalist system, which is long overdue, and no revolutionary communist party to guide it in this noble cause of overthrowing capitalism and building socialism through revolution. Theory, which refers to the objective sphere, the opposite of pragmatism, shows that it is the working class itself which must go into action, which must provide itself with the necessary consciousness and organization to organize itself as a class, to be conscious of itself as a class. Modern large-scale industry, modern capitalist society, has given rise to a modern proletariat which must provide itself with revolutionary class consciousness. It must bring forth revolutionary intelligentsia and win over to its cause those coming from the petty bourgeoisie and middle strata in order to isolate the bourgeoisie to the extreme. The conclusion is therefore that the working class must emancipate itself and its emancipation cannot be the act of other classes. Taken with the conclusion of the necessity of a proletarian party, it follows that the vanguard of the working class must be guided by Marxism-Leninism to work out and provide the working class with a revolutionary theory.
