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.

The clergy, no less than the capitalist class, lives on the backs of the people, profits from the degradation, the ignorance and the oppression of the people.

The victory of socialism will not descend like fate from heaven.

Freedom only for the members of the government, only for the members of the Party - though they are quite numerous - is no freedom at all.

Tomorrow the revolution will already 'raise itself with a rattle' and announce with fanfare, to your terror: I was, I am, I will be!

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.

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