Ignorance never yet helped anybody.

Nothing can have value without being an object of utility.

From each according to his abilities, to each according to his needs.

Education is free. Freedoom of education shall be enjoyed under the condition fixed by law and under the supreme control of the state.

Revolutions are the locomotives of history.

Change the economic base and you will change human beings.

Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win. Workingmen of all countries unite!

Man makes his own history, but he does not make it out of the whole cloth; he does not make it out of conditions chosen by himself, but out of such as he finds close at hand.

We have no compassion and we ask no compassion from you. When our turn comes, we shall not make excuses for the terror.
