“O vitae Philosophia dux! O virtutum indagatrix expultrixque vitiorum! Unus dies, bene et ex praeceptis tuis actus, peccanti immortalitati est anteponendus.

translation (non-literal):
O philosophy, life’s guide! O searcher of virtues and expeller of vices! Just a single day lived well and according to your lessons is to be preferred to an eternity of errors.

— Cicero, As quoted in Ben Franklin’s Autobiography”

“If an injury has to be done to a man it should be so severe that his vengeance need not be feared.”
― Niccolo Machiavelli, The Prince

“it is much safer to be feared than loved because ...love is preserved by the link of obligation which, owing to the baseness of men, is broken at every opportunity for their advantage; but fear preserves you by a dread of punishment which never fails.”
― Niccolo Machiavelli, The Prince

“Never attempt to win by force what can be won by deception.”
― Niccolò Machiavelli, The Prince
