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.

There is no democracy without socialism, and no socialism without democracy.

The working classes in every country only learn to fight in the course of their struggles.

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

Freedom for supporters of the government only, for members of one party only no matter how big its membership may be is no freedom at all. Freedom is always freedom for the man who thinks differently.

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

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