Marxism is a revolutionary worldview that must always struggle for new revelations.

Freedom is always and exclusively freedom for the one who thinks differently.

Before a revolution happens, it is perceived as impossible; after it happens, it is seen as having been inevitable.

The masses are the decisive element, they are the rock on which the final victory of the revolution will be built.

Those who don't move don't notice their chains.

History is the only true teacher, the revolution the best school for the proletariat.

The working classes in every country only learn to fight in the course of their struggles...Social democracy...is only the advance guard of the proletariat, a small piece of the total working masses; blood from their blood, and flesh from their flesh. Social democracy seeks and finds the ways, and particular slogans, of the workers' struggle only in the course of the development of this struggle, and gains directions for the way forward through this struggle alone.
