"The revolutionary epoch demands that the proletariat should employ such fighting methods as will concentrate its entire energy, viz., the method of mass action, and lead to its logical consequence--the direct collision with the capitalist state machine in an open combat. All other methods, e.g., revolutionary use of bourgeois parliamentarism will in the revolution have only a subordinate value." It is very significant, therefore, that the Socialist Party of America definitely committed itself to these tactics in the manifesto it adopted at the Chicago Emergency Convention on September 4, 1919. As given in the "Call" of September 5, 1919, the manifesto of the Socialist Party of the United States says on this point: "The great purpose of the Socialist Party is to wrest the industries and the control of the Government of the United States from the capitalists and their retainers. It is our purpose to place industry and government in the control of the workers with hand and brain, to be administered for the benefit of the whole community. "To insure the triumph of Socialism in the United States the bulk of the American workers must be strongly organized politically as Socialists, in constant, clear-cut and aggressive opposition to all parties of the possessing class. They must be strongly organized in the economic field on broad industrial lines, as one powerful and harmonious class organization, co-operating with the Socialist Party, and ready in cases of emergency to reinforce the political demands of the working class by industrial action. "To win the American workers from their ineffective and demoralizing leadership, to educate them to an enlightened understanding of their own class interests, and to train and assist them to organize politically and industrially on class lines, in order to effect their emancipation, that is the supreme task confronting the Socialist Party in America. "To this great task, without deviation or compromise, we pledge all our energies and resources. For its accomplishment we call for the support and co-operation of the workers of America and of all other persons desirous of ending the insane rule of capitalism before it has had the opportunity to precipitate humanity into another cataclysm of blood and ruin. "Long live the International Socialist Revolution, the only hope of the suffering world!"
