"Hypocrisy is a tribute vice pays to virtue,” said La Rochefoucauld. The hypocrite who hypocritically says one thing yet does the opposite is paying a tribute to virtue because deep down he knows what is right, though he lacks the moral fortitude to act upon it. There likely is a Latin translation floating around somewhere; moral admonitions sound so much better in Latin.
U.S. Senator Dick Blumenthal used an unfortunate Latin expression in questioning Supreme Court prospect – over Blumenthal’s dead body! – Brett Kavanaugh. He asked Kavanaugh, whose repute now lies in tatters thanks to a triumvirate of leading Senate muckrakers -- Blumenthal, Dianne Feinstein and Chuck Schumer -- Kavanaugh was familiar with the Latin phrase “Falsus in uno, falsus in omnibus,” a rough translation of which is: “False in one thing, false in all things.” The implication is that if one misrepresents objective reality even once, everything one has said previously is false; indeed, everything one may say AFTER the presumed falsehood is also false.
