Anarchism or Socialism (1906)
Context: We are not the kind of people who, when the word "anarchism" is mentioned, turn away contemptuously and say with a supercilious wave of the hand: "Why waste time on that, it's not worth talking about!" We think that such cheap "criticism" is undignified and useless.
Nor are we the kind of people who console themselves with the thought that the Anarchists "have no masses behind them and, therefore, are not so dangerous." It is not who has a larger or smaller "mass" following today, but the essence of the doctrine that matters. If the "doctrine" of the Anarchists expresses the truth, then it goes without saying that it will certainly hew a path for itself and will rally the masses around itself. If, however, it is unsound and built up on a false foundation, it will not last long and will remain suspended in mid-air. But the unsoundness of anarchism must be proved.
Some people believe that Marxism and anarchism are based on the same principles and that the disagreements between them concern only tactics, so that, in the opinion of these people, no distinction whatsoever can be drawn between these two trends.
This is a great mistake.
We believe that the Anarchists are real enemies of Marxism. Accordingly, we also hold that a real struggle must be waged against real enemies.
