From Counterpunch:
Hannah Arendt, an émigré from Nazi Germany.
“The result of a consistent and total substitution of lies for factual truth,” Arendt wrote in her classic volume The Origins of Totalitarianism, “is not that the lie will now be accepted as truth and truth be defamed as a lie, but that the sense by which we take our bearings in the real world—and the category of truth versus falsehood is among the mental means to this end—is being destroyed.”
