The Class Struggle (Engels quote)

Great stress is laid on the dictum that Communism is not a mere party doctrine of the working class, but a theory compassing the emancipation of Society at large, including the capitalist class, from its present narrow conditions. This is true enough in the abstract, but absolutely useless, and sometimes worse, in. practice. So long as the wealthy classes not only do not feel the want of any emancipation, but strenuously oppose the self-emancipation of the working class, so long the social revolution will have to be prepared and fought out by the working class alone.

The French Bourgeois of 1789, too, declared the emancipation of the bourgeoisie to be the emancipation of the whole human race; but the nobility and clergy would not see it; the proposition—though for the time being, with respect to feudalism, an abstract historical truth—soon became a mere sentimentalism, and disappeared from view altogether in the fire of the revolutionary struggle. And to-day, the very people who, from the “impartiality” of their superior standpoint, preach to the workers a Socialism soaring high above their class interests and class struggles, and tending to reconcile in a higher humanity the interests of both the contending classes—these people are either neophytes, who have still to learn a great deal, or they are the worst enemies of the workers,—wolves in sheep’s clothing.

FREDERICK ENGELS, 1892.
