The purity of our principles, the idealism of our struggle, these are factors of strengthening and drawing power that have given to us courage for al… - Wilhelm Liebknecht

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.

Membership in the social democracy means a struggle, a political struggle with grievous persecutions, and a private struggle for existence, a struggle that for the majority is far more difficult and heavy than the political struggle. And it is necessary, because the courage for this twofold struggle is created only by the consciousness that the injustice of society by which the great majority of mankind are to-day oppressed, corrupted and crippled, can only be abolished through a revolutionary movement, that is, a movement that shall completely exterminate capitalism with every fiber of its roots.
