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 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.

Capitalism, as a result of its own inner contradictions, moves toward a point when it will be unbalanced, when it will simply become impossible.

Only to the rude ear of one who is quite indifferent does the song of a bird seem always the same.

Before a revolution happens, it is perceived as impossible; after it happens, it is seen as having been inevitable.

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.

Freedom is always the freedom of dissenters.
