Diversity of opinions on theoretical points is never dangerous to the party. There are for us no bounds to criticism, and however great our respect m… - Wilhelm Liebknecht

The highest triumph of Bismarckian politics carried its downfall and bankruptcy within it.

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.

All parties without exception recognize us as a political power, and exactly in proportion to our power. Even the craziest reactionary that denies us the right of existence courts our favor and by his acts gives the lie to his words. From the fact that our assistance is sought by other parties, some of our comrades draw the strange conclusion that we should reverse the party tactics, and in place of the old policy of the class struggle against all other parties, substitute the commercial polities of log rolling, wire pulling and compromise. Such persons forget the power which makes our alliance sought for, even by our bitterest enemies, would have had absolutely no existence were it not for the old class struggle tactics. If Marx, Engels and Lassalle had accepted from Bernstein and his modest or not modest fellow thinkers the tactics of compromise and dependence upon bourgeois parties, then there never would have been any Social Democracy; we would have been simply the tail of the Progressive party.
