Violations of Reality and Indifference – George Orwell on Manipulation

"In an ever-changing, incomprehensible world the masses had reached the point where they would, at the same time, believe everything and nothing, think that everything was possible and that nothing was true. ... Mass propaganda discovered that its audience was ready at all times to believe the worst, no matter how absurd, and did not particularly object to being deceived because it held every statement to be a lie anyhow. The totalitarian mass leaders based their propaganda on the correct psychological assumption that, under such conditions, one could make people believe the most fantastic statements one day, and trust that if the next day they were given irrefutable proof of their falsehood, they would take refuge in cynicism; instead of deserting the leaders who had lied to them, they would protest that they had known all along that the statement was a lie and would admire the leaders for their superior tactical cleverness." Hannah Arendt

"The holders of authority and those who take advantage of it must convince people of this fiction and put to sleep their realistic, that is to say, critical, faculty of thought. Every thinking person knows the methods of propaganda, methods by which critical judgment is destroyed and the mind is lulled until it submits to clichés that stultify people because they make them dependent, depriving them of the ability to trust their eyes and their judgment. This function, in which they believe, blinds them to reality." Erich Fromm
