The similarity of these two phenomena so different in their forms comes out most clearly in the final results at the close of the period. The English proletariat in the struggle to meet its daily issues was forced to form an independent party of its own, without, however, breaking with its liberal traditions; and the party of the German proletariat, when the War forced upon it the necessity of a decisive choice, gave an answer in the spirit of the national-liberal traditions of the English labor party. Marxism, of course, was not merely something accidental or insignificant in the German labor movement. Yet there would be no basis for deducing the social-revolutionary character of the Party from its official Marxist ideology. Ideology is an important, but not a decisive factor in politics. Its rôle is that of waiting on politics. That deep-seated contradiction, which was inherent in the awakening revolutionary class on account of its relation to the feudal-reactionary state, demanded an irreconcilable ideology which would bring the whole movement under the banner of social revolutionary aims. Since historical conditions forced opportunist tactics, the irreconcilability of the proletarian class found expression in the revolutionary formulas of Marxism. Theoretically, Marxism reconciled with perfect success the contradiction between reform and revolution. Yet the process of historical development is something far more involved than theorizing in the realm of pure thought. The fact that the class which was revolutionary in its tendencies was forced for several decades to adapt itself to the monarchical police state, based on the tremendous capitalistic development of the country, in the course of which adaptation an organization of a million members was built up and a labor bureaucracy which led the entire movement was educated--this fact does not cease to exist and does not lose its weighty significance because Marxism anticipated the revolutionary character of the future movement. Only the most naïve ideology could give the same place to this forecast that it does to the political actualities of the German labor movement.
