Perhaps you will point to the Paris Commune; but apart from the fact that this was merely the rising of a town under exceptional conditions, the majority of the Commune was in no sense socialist, nor could it be. With a small amount of sound common sense, however, they could have reached a compromise with Versailles useful to the whole mass of the people -- the only thing that could be reached at the time. The appropriation of the Bank of France alone would have been enough to dissolve all the pretensions of the Versailles people in terror, etc., etc. The general demands of the French bourgeoisie laid down before 1789 were roughly just the same, mutatis mutandis [with corresponding alterations] as the first immediate demands of the proletariat are pretty uniformly to-day in all countries with capitalist production. But had any eighteenth-century Frenchman the faintest idea a priori beforehand of the way in which the demands of the French bourgeoisie would be accomplished? The doctrinaire and necessarily fantastic anticipations of the programme of action for a revolution of the future only divert us from the struggle of the present. The dream that the end of the world was at hand inspired the early Christians in their struggle with the Roman Empire and gave them confidence in victory. Scientific insight into the inevitable disintegration of the dominant order of society continually proceeding before our eyes, and the ever-growing passion into which the masses are scourged by the old ghosts of government--while at the same time the positive development of the means of production advances with gigantic strides--all this is a sufficient guarantee that with the moment of the outbreak of a real proletarian revolution there will also be given the conditions (though these are certain not to be idyllic) of its next immediate modus operandi [form of action]. It is my conviction that the critical juncture for a new International Workingmen's Association has not yet arrived and for this reason I regard all workers' congresses, particularly socialist congresses, in so far as they are not related to the immediate given conditions in this or that particular nation, as not merely useless but harmful. They will always fade away in innumerable stale generalised banalities.
