If, therefore, the Russian Revolution* teaches us anything, it teaches above all that the mass strike is not artificially "made," not "decided" at random, not "propagated," but that it is a historical phenomenon which, at a given moment, results from social conditions with historical inevitability. It is not, therefore, by abstract speculations on the possibility or impossibility, the utility or the injuriousness of the mass strike, but only by an examination of those factors and social conditions out of which the mass strike grows in the present phase of the class struggle–in other words, it is not by subjective criticism of the mass strike from the standpoint of what is desirable, but only by objective investigation of the sources of the mass strike from the standpoint of what is historically inevitable, that the problem can be grasped or even discussed.
