The masses are in reality their own leaders, dialectically creating their own development process.

The most revolutionary thing one can do is always to proclaim loudly what is happening.

The most revolutionary act is a clear view of the world as it really is.

We will be victorious if we have not forgotten how to learn.

Friedrich Engels once said: "Bourgeois society stands at the crossroads, either transition to socialism or regression into barbarism." What does "regression into barbarism" mean to our lofty European civilization? Until now, we have all probably read and repeated these words thoughtlessly, without suspecting their fearsome seriousness. A look around us at this moment shows what the regression of bourgeois society into barbarism means. This world war is a regression into barbarism. The triumph of imperialism leads to the annihilation of civilization.

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.
