During the lifetime of great revolutionaries, the oppressing classes have visited relentless persecution on them and received their teaching with the most savage hostility, the most furious hatred, the most ruthless campaign of lies and slander.

After their death, attempts are made to turn them into harmless icons, canonize them, and surround their names with a certain halo for the “consolation” of the oppressed classes and with the object of duping them, while at the same time emasculating and vulgarizing the real essence of their revolutionary theories and blunting their revolutionary edge.
