I have an honest lad to my tailor, whom I never knew guilty of one truth, no, not when it had been to his advantage. 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. The Pythagoreans make good to be certain and finite, and evil, infinite and uncertain. There are a thousand ways to miss the white, there is only one to hit it. For my own part, I have this vice in so great horror, that I am not sure I could prevail with my conscience to secure myself from the most manifest and extreme danger by an impudent and solemn lie. An ancient father says "that a dog we know is better company than a man whose language we do not understand."
"Ut externus alieno pene non sit hominis vice."
[As a foreigner cannot be said to supply us the place of a man."--Pliny, Nat. Hist. vii. I]
And how much less sociable is false speaking than silence?
King Francis I. vaunted that he had by this means nonplussed Francesco Taverna, ambassador of Francesco Sforza, Duke of Milan, a man very famous for his science in talking in those days. This gentleman had been sent to excuse his master to his Majesty about a thing of very great consequence, which was this: the King, still to maintain some intelligence with Italy, out of which he had lately been driven, and particularly with the duchy of Milan, had thought it convenient to have a gentleman on his behalf to be with that Duke: an ambassador in effect, but in outward appearance a private person who pretended to reside there upon his own particular affairs; for the Duke, much more depending upon the Emperor, especially at a time when he was in a treaty of marriage with his niece, daughter to the King of Denmark, who is now dowager of Lorraine, could not manifest any practice and conference with us without his great interest. For this commission one Merveille, a Milanese gentleman, and an equerry to the King, being thought very fit, was accordingly despatched thither with private credentials, and instructions as ambassador, and with other letters of recommendation to the Duke about his own private concerns, the better to mask and colour the business; and was so long in that court, that the Emperor at last had some inkling of his real employment there; which was the occasion of what followed after, as we suppose; which was, that under pretence of some murder, his trial was in two days despatched, and his head in the night struck off in prison. Messire Francesco being come, and prepared with a long counterfeit history of the affair (for the King had applied himself to all the princes of Christendom, as well as to the Duke himself, to demand satisfaction), had his audience at the morning council; where, after he had for the support of his cause laid open several plausible justifications of the fact, that his master had never looked upon this Merveille for other than a private gentleman and his own subject, who was there only in order to his own business, neither had he ever lived under any other aspect; absolutely disowning that he had ever heard he was one of the King's household or that his Majesty so much as knew him, so far was he from taking him for an ambassador: the King, in his turn, pressing him with several objections and demands, and challenging him on all sides, tripped him up at last by asking, why, then, the execution was performed by night, and as it were by stealth? At which the poor confounded ambassador, the more handsomely to disengage himself, made answer, that the Duke would have been very loth, out of respect to his Majesty, that such an execution should have been performed by day. Any one may guess if he was not well rated when he came home, for having so grossly tripped in the presence of a prince of so delicate a nostril as King Francis.
Pope Julius II. having sent an ambassador to the King of England to animate him against King Francis, the ambassador having had his audience, and the King, before he would give an answer, insisting upon the difficulties he should find in setting on foot so great a preparation as would be necessary to attack so potent a King, and urging some reasons to that effect, the ambassador very unseasonably replied that he had also himself considered the same difficulties, and had represented them to the Pope. From which saying of his, so directly opposite to the thing propounded and the business he came about, which was immediately to incite him to war, the King of England first derived the argument (which he afterward found to be true), that this ambassador, in his own mind, was on the side of the French; of which having advertised his master, his estate at his return home was confiscated, and he himself very narrowly escaped the losing of his head. --[Erasmi Op.
