The more that social democracy develops, grows, and becomes stronger, the more the enlightened masses of workers will take their own destinies, the leadership of their movement, and the determination of its direction into their own hands.

Marxism must abhor nothing so much as the possibility that it becomes congealed in its current form. It is at its best when butting heads in self-criticism, and in historical thunder and lightning, it retains its strength.

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

Freedom is always the freedom of dissenters.

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

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

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.
