If falsehood, like truth, had but one face, we would be more on equal terms. For we would consider the contrary of what the liar said to be certain. But the opposite of truth has a hundred thousand faces and an infinite field.Michel de Montaigne (1533-1592) French essayist
Essays, Bk. I, ch. 9 “Of Liars” (1575)
Alt trans. [C. Cotton (1877)]: "If falsehood had, like truth, but one face only, we should be upon better terms; for we should then take for certain the contrary to what the liar says: but the reverse of truth has a hundred thousand forms, and a field indefinite, without bound or limit."
Alt trans. [Florio (1603)]: "If a lie had no more faces but one, as truth had, we should be in farre better termes than we are: For whatsoever a lier should say, we would take it in a contrarie sense. But the opposite of truth has many shapes, and an undefinite field."
