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

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

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

Self-criticism, cruel, unsparing criticism that goes to the very root of the evil, is life and breath for the proletarian movement.

Without general elections, without freedom of the press, freedom of speech, freedom of assembly, without the free battle of opinions, life in every public institution withers away, becomes a caricature of itself, and bureaucracy rises as the only deciding factor.

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