“If you repeat a lie often enough, people will believe it, and you will even come to believe it yourself.” (misattributed) “The best propaganda is that which, as it were, works invisibly, penetrates the whole of life without the public having any knowledge of the propagandistic initiative.”
Joseph Goebbels, from en.wikiquote.org

“This process of continuous alteration was applied not only to newspapers, but to books, periodicals, pamphlets, posters, leaflets, films, sound−tracks, cartoons, photographs – to every kind of literature or documentation which might conceivably hold any political or ideological significance.” “And if all others accepted the lie which the Party imposed – if all records told the same tale — then the lie passed into history and became truth.”
George Orwell, Nineteen Eighty−Four

“No man knows the meaning of ANYTHING published in any newspaper if he doesn't know which interests control the newspaper.”
“We NEVER know enough.”
Ezra Pound, from it.wikiquote.org, some quoted in Giacinto Auriti, Il Paese dell'Utopia (The Land of Utopia, author’s note)

“The media monopoly deals with its opponents in one of two ways; either frontal assault of libel which the average person cannot afford to litigate, or an iron curtain of silence, the standard treatment for any work which exposes its clandestine activities.”
Eustace Mullins, The Secrets of the Federal Reserve, The London Connection

“… it is the villains' attorneys and the media legal departments the ones that de facto decide what you will get to know, taking advantage of the just fear of many a journalist which risk the ruin of their families if they tell the truth.”
Paolo Barnard, Censura Legale (Legal Censorship, author's note), as found at paolobarnard.info
