We dare not do all that our opponents do. We dare not sacrifice everything for advantages. For what is an advantage to our opponents is deadly poison… - Wilhelm Liebknecht

We shall never go wrong if we do what is opposed to the interests of our enemy. On the other hand, we shall almost never go right if we do what our enemies applaud. Historical development is a continuous conflict, a conflict of interests, a conflict of races, a conflict of classes. And if friendship does not count even in ordinary business, how much less so in such a conflict. Good-naturedness and sentimentality have no place in politics. They have never won a victory, but have brought unnumbered defeats. Bluecher’s motto, “Always follow the cannon’s roar and throw yourself upon the enemy,” is the best rule also in .

When I speak here of our policy, I use the word without regard to anything immaterial and superficial, but in the sense which since the beginning of the party it has had for us in contrast to all other parties, – in the sense of the policy of the class struggle, which has very often changed in form, but in substance has remained the same, – our unique proletarian class policy, which separates us from all other political parties in the world of bourgeois society and excludes us from intercourse with them.

We may not do as other parties, because we are not like the others. We are – and this cannot be too often repeated – separated from all other parties by an insurmountable barrier, a barrier that any individual can easily surmount; but once on the other side of it, and he is no Social Democrat. We are different from the others; “we are other than the others.” What for the others are necessities and conditions of life are death to us.
