Propaganda

The task of propaganda lies not in weighing right and wrong, but driving home your own point of view. You cannot objectively explore the facts that favors others and present them in doctrinaire sincerity to the masses. You have to push relentlessly your own case...

Even the most brilliant propaganda will not produce the desired results unless it follows this fundamental rule: You must stick to limiting yourself to essentials and repeat them endlessly. Persistence on this point, as in so many other cases in the world, is the first and most important precondition for success...

Propaganda does not exist to furnish interesting diversions to the blase' young dandies, but to convince above all the masses. In their clumsiness they always require a long lead before they are ready to take notice. Only by thousandfold repetition will the simplest concept stick in their memories.
