People have learned by bitter experience that the "European fraternal union of peoples" cannot be achieved by mere phrases and pious wishes, but only by profound revolutions and bloody struggles; they have learned that the question is not that of a fraternal union of all European peoples under a single republican flag, but of an alliance of the revolutionary peoples against the counter-revolutionary peoples, an alliance which comes into being not on paper, but only on the battlefield.
Friedrich EngelsJust as Marx used to say about the French Marxists of the late 'seventies: All I know is that I am not a Marxist.
Friedrich EngelsWe find two great gangs of political speculators, who alternately take possession of the state power and exploit it by the most corrupt ends -- the nation is powerless against these two great cartels of politicians who are ostensibly its servants, but in reality dominate and plunder it.
Friedrich Engels...it was always our view that in order to attain this [proletarian revolution] and the other far more important aims of the future social revolution, the working class must first take possession of the organised political power of the state and by its aid crush the resistance of the capitalist class and organise society anew.
