"The emancipation of the workers is the task of the workers themselves."

"Every emancipation is a restoration of the human world and of human relationships to man himself."

"The first step in the revolution by the working class is to raise the proletariat to the position of ruling class to win the battle of democracy."

"The worker is the owner of his labour power, but he cannot sell it without selling himself."

"History is thorough and goes through many phases when carrying an old form to the grave. The last phase of a world-historical form is its comedy."
