We Social Democrats dare not be like the other parties, all of whom are equally guilty of the injustices of the present system and equally responsibl… - Wilhelm Liebknecht

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.

All who are weary and heavy laden; all who suffer under injustice; all who suffer from the outrages of the existing bourgeois society; all who have in them the feeling of the worth of humanity, look to us, turn hopefully to us, as the only party that can bring rescue and deliverance. And if we, the opponents of this unjust world of violence, suddenly reach out the hand of brotherhood to it, conclude alliances with its representatives, invite our comrades to go hand in hand with the enemy whose misdeeds have driven the masses into our camp, what confusion must result in their minds! ... It must be that for the hundreds and thousands, for the millions that have sought salvation under our banner, it was all a colossal mistake for them to come to us. If we are not different from the others, then we are not the right ones – the Savior is yet to come; and the Social Democracy was a false Messiah, no better than the other false ones! Just in this fact lies our strength, that we are not like the others, and that we are not only not like the others, and that we are not simply different from the others, but that we are their deadly enemy, who have sworn to storm and demolish the Bastile of Capitalism, whose defenders all those others are. Therefore we are only strong when we are alone. This is not to say that we are to individualise or to isolate ourselves. We have never lacked for company, and we never shall so long as the fight lasts. On the essentially true but literally false phrase about a “single reactionary mass,” the Social Democracy has never believed since it passed from the realm of theory to that of practice. We know that the individual members and divisions of the “single reactionary mass” are in conflict with each other, and we have always used these conflicts for our purposes. We have used opponents against opponents, but have never allowed them to use us.

If the way to hell is paved with good intentions, the way to defeat is paved with illusions.
