Repeating

"If you tell a lie big enough and keep repeating it, people will eventually come to believe it. The lie can be maintained only for such time as the State can shield the people from the political, economic and/or military consequences of the lie. It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the State."
-- Joseph Goebbels, German Minister of Propaganda, 1933-1945


"See, in my line of work you got to keep repeating things over and over and over again for the truth to sink in, to kind of catapult the propaganda." - George W Bush
