out these it could not be. Socialism and ethics are two separate things. This fact must be kept in mind.
Whoever conceives of socialism in the sense of a sentimental philanthropic striving after human equality, with no idea of the existence of capitalist society, is no socialist in the sense of the class struggle, without which modern socialism is unthinkable. To be sure Bernstein is nominally for the class struggle—in the same manner as the Hessian peasant is for "the Republic and the Grand Duke." Whoever has come to a full consciousness of the nature of capitalist society and the foundation of modern socialism, knows also that a socialist movement that leaves the basis of the class struggle, may be anything else, but it is not socialism.
This foundation of the class struggle, which Marx—and this is his immortal service—has given to the modern labor movement, is the main point of attack in the battle which the bourgeois political economy is waging with socialism. The political economists deny the class struggle and would make of the labor movement only a part of the bourgeois party movements, and the Social Democracy only a division of the bourgeois democracy. The bourgeois political economy and politics direct all their exertions against the class character of the modern labor movement. If it were possible to create a breach in this bulwark, in this citadel of the Social Democracy, then the Social Democracy is conquered, and the proletariat thrown back under the dominion of capitalist society. However small such a breach may be in the beginning, the enemy has the power to widen it and the certainty of final victory. And the enemy is most dangerous when he comes as a friend to the fortress, when he slinks in under the cover of friendship, and is recognized as a friend and comrade.
