We are told constantly that Donald Trump’s lies corrode the life of our Republic. Jacob Levy of the Niskanen Center invoked Hannah Arendt on the subject, and said that Trump uses lies the way authoritarians do, to demonstrate and expand their power, by “making his surrogates repeat the lies [he] compromised them; that tied them to him. And it degraded them, and made clear where power lay.” James Pfiffner of the Brookings Institute solemnly argued that Trump’s lies are different than past presidential fibs because Trump doesn’t try to equivocate, and that they thus “challenge the fundamental principles of the Enlightenment.”
