If you don’t want a man unhappy politically, don’t give him two sides to a question to worry him; give him one. Better yet, give him none. Let him forget there is such a thing as war. If the government is inefficient, top-heavy, and tax-mad, better it be all those than that people worry over it…. Give the people contests they win by remembering the words to more popular songs or the names of state capitals or how much corn Iowa grew last year. Cram them full of noncombustible data, chock them so damned full of ‘facts’ they feel stuffed, but absolutely ‘brilliant’ with information. Then they’ll feel they’re thinking, they’ll get a sense of motion without moving. And they’ll be happy, because facts of that sort don’t change. - Ray Bradbury, Fahrenheit 451
How do you change the way people think? You start by changing the words they use.
In totalitarian regimes—a.k.a. police states—where conformity and compliance are enforced at the end of a loaded gun, the government dictates what words can and cannot be used. In countries where the police state hides behind a benevolent mask and disguises itself as tolerance, the citizens censor themselves, policing their words and thoughts to conform to the dictates of the mass mind.
