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.
