Original Big lie quote intended to describe, "behavior of Jews" according to Jewish Virtual Library
“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.”
This is an excellent definition of the “Big lie,” however, there seems to be no evidence that it was used by Nazi propaganda chief Joseph Goebbels, though it is often attributed to him.
The original description of the big lie appeared in Mein Kampf. Adolf Hitler applied it to the behavior of Jews rather than as a tactic he advocated.
