Every provisional political set-up following a revolution requires a dictatorship, and an energetic dictatorship at that.

The bourgeoisie of the whole world, which looks complacently upon the wholesale massacre after the battle, is convulsed by horror at the desecration of brick and mortar.

Nothing can have value without being an object of utility.

The Jews of Poland are the smeariest of all races.

In a higher phase of communist society... only then can the narrow horizon of bourgeois right be fully left behind and society inscribe on its banners: from each according to his ability, to each according to his needs.
