Bare-faced covetousness was the moving spirit of civilization from its first dawn to the present day; wealth, and again wealth, and for the third time wealth; wealth, not of society, but of the puny individual, was its only and final aim.
Friedrich EngelsIf in all ideology men and their circumstances appear upside-down as in a camera obscura, this phenomenon arises just as much from their historical life-process as the inversion of objects on the retina does from the physical life-process.
Friedrich EngelsPeople 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.
