The whole struggle of our Party (and of the working class movement in Europe generally) must be directed against opportunism. The latter is not a current of opinion, not a tendency; it (opportunism) has now become the organised tool of the bourgeoisie within the working class movement.
Vladimir LeninYou can become a Communist only when you enrich your mind with a knowledge of all the treasures created by mankind.
Vladimir LeninComrades! The kulak uprising in your five districts must be crushed without pity. You must make example of these people. (1) Hang (I mean hang publicly, so that people see it) at least 100 kulaks, rich bastards, and known bloodsuckers. (2) Publish their names. (3) Seize all their grain. (4) Single out the hostages per my instructions in yesterday's telegram. Do all this so that for miles around people see it all, understand it, tremble, and tell themselves that we are killing the bloodthirsty kulaks and that we will continue to do so ...Find tougher people.
