It is double pleasure to deceive the deceiver. - Niccolò Machiavelli

Whether this has ever happened I know not, nor whether it ever can happen. For we see, as I have said a little way back, that a city which owing to its pervading corruption has once begun to decline, if it is to recover at all, must be saved not by the excellence of the people collectively, but of some one man then living among them, on whose death it at once relapses into its former plight; as happened with Thebes, in which the virtue of Epaminondas made it possible while he lived to preserve the form of a free Government, but which fell again on his death into its old disorders; the reason being that hardly any ruler lives so long as to have time to accustom to right methods a city which has long been accustomed to wrong.

For this reason a prince ought to take care that he never lets anything slip from his lips that is not replete with the above-named five qualities, that he may appear to him who sees and hears him altogether merciful, faithful, humane, upright, and religious. There is nothing more necessary to appear to have than this last quality, inasmuch as men judge generally more by the eye than by the hand, because it belongs to everybody to see you, to few to come in touch with you. Every one sees what you appear to be, few really know what you are, and those few dare not oppose themselves to the opinion of the many, who have the majesty of the state to defend them; and in the actions of all men, and especially of princes, which it is not prudent to challenge, one judges by the result.

For it must be noted, that men must either be caressed or else annihilated; they will revenge themselves for small injuries, but cannot do so for great ones; the injury therefore that we do to a man must be such that we need not fear his vengeance.
