ike of others in comparison of truth.
Apollonius said it was for slaves to lie, and for freemen to speak truth:
'tis the chief and fundamental part of virtue; we must love it for
itself. He who speaks truth because he is obliged so to do, and because
it serves him, and who is not afraid to lie when it signifies nothing to
anybody, is not sufficiently true. My soul naturally abominates lying,
and hates the very thought of it. I have an inward shame and a sharp
remorse, if sometimes a lie escapes me: as sometimes it does, being
surprised by occasions that allow me no premeditation. A man must not
always tell all, for that were folly: but what a man says should be what
he thinks, otherwise 'tis knavery. I do not know what advantage men
pretend to by eternally counterfeiting and dissembling, if not never to
be believed when they speak the truth; it may once or twice pass with
men; but to profess the concealing their thought, and to brag, as some of
our princes have done, that they would burn their shirts if they knew
their true intentions, which was a saying of the ancient Metellius of
Macedon; and that they who know not how to dissemble know not how to
rule, is to give warning to all who have anything to do with them, that
all they say is nothing but lying and deceit:

"Quo quis versutior et callidior est, hoc invisior et
suspectior, detracto opinione probitatis:"

["By how much any one is more subtle and cunning, by so much is he
hated and suspected, the opinion of his integrity being withdrawn."
--Cicero, De Off., ii. 9.]

it were a great simplicity in any one to lay any stress either on the
countenance or word of a man who has put on a resolution to be always
another thing without than he is within, as Tiberius did; and I cannot
conceive what part such persons can have in conversation with men, seeing
they produce nothing that is received as true: whoever is disloyal to
truth is the same to falsehood also.

Those of our time who have considered in the establishment of the duty of
a prince the good of his affairs only, and have preferred that to the
care of his faith and conscience, might have something to say to a prince
whose affairs fortune had put into such a posture that he might for ever
establish them by only once breaking his word: but it will not go so;
they often buy in the same market; they make more than one peace and
enter into more than one treaty in their lives.
