Those who do not move, do not notice their chains.

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

Life is singing also in the sand crunching under the slow and heavy steps of the guards, when we know how to listen to it.

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.

Being human means throwing your whole life on the scales of destiny when need be, all the while rejoicing in every sunny day and every beautiful cloud.

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.

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