We recognize no infallible Pope, not even a literary one. - Wilhelm Liebknecht

The supreme importance of tactics and the necessity of maintaining its class struggle character, is something the party has been well conscious of from the beginning. ... We find that in all questions of tactics the thought was continually kept in the foreground that the party must be kept clean from all mixture with all other parties, every one of which, no matter how much they differed from each other or how furiously they fought among themselves, stood upon the ground of bourgeois society as a common basis. This separation of the Social Democracy from all other parties, this essential difference, which silly opponents take as a reason or pretext for declaring us political outlaws, is our pride and our strength.

As Prince Bismarck, in the ’60s, wanted to move the “Acheron” of socialism, ... it was of course not love for socialism or knowledge of socialism that led Prince Bismarck to do this. He understood nothing about socialism at that time, and never did understand anything about it down to his death; in fact, he never had any conception of the moving forces of political and social life at all. There probably never lived at any time in any country a “statesman” who was less scientific, who had less knowledge, and who relied so purely on experience and a sort of half-gambler, half-peddler cunning, as Bismarck. Those offers to socialists place in the clearest light the untruthfulness of Prince Bismarck’s claim that he always regarded the social democracy as incompatible with the existence of the state. Bismarck wanted to use socialism for the purpose of breaking up and dissolving the bourgeois liberal opposition, especially the Progressive party. This, in itself, is the most conclusive proof that he had no conception of the real nature of socialism. Of course the fate of the boy magician was repeated. The elemental force which was conjured up grew over the head of the dabbler, and he did not get the best of socialism; socialism got the best of him.

It would be an unparalleled case of flying the track and going astray if the German Social Democracy, which has had such wonderful success and such a wonderful growth for the very reason that it has marched ahead unterrified on the basis of the class struggle, should suddenly face about and plunge into mistakes, the avoidance of which has been the power and pride of our party, and has put the German Social Democracy at the head of the international social democracy of all countries.
