“Without Revolutionary theory, there can be no Revolutionary Movement.”

“During the lifetime of great revolutionaries, the oppressing classes constantly hounded them, received their theories with the most savage malice, the most furious hatred and the most unscrupulous campaigns of lies and slander. After their death, attempts are made to convert them into harmless icons, to canonize them, so to say, and to hallow their names to a certain extent for the “consolation” of the oppressed classes and with the object of duping the latter, while at the same time robbing the revolutionary theory of its substance, blunting its revolutionary edge and vulgarizing it.”

“Attention, must be devoted principally to raising the workers to the level of revolutionaries; it is not our task to descend to the level of the 'working masses'.”

“Can a nation be free if it oppresses other nations? It cannot.”

“A lie told often enough becomes the truth.”

“Despair is typical of those who do not understand the causes of evil, see no way out, and are incapable of struggle.”

“Freedom in capitalist society always remains about the same as it was in ancient Greek republics: Freedom for slave owners.”
