A man who wishes to make a profession of goodness in everything must necessarily come to grief among so many who are not good. Therefore, it is necessary for a prince, who wishes to maintain himself, to learn how not to be good, and to use this knowledge and not use it according to the necessity of the case.
Niccolo MachiavelliAnd if such malignity is hidden for a time, it proceeds from the unknown reason that would not be known because the experience of the contrary had not been seen, but time, which is said to be the father of every truth, will cause it to be discovered.
Niccolo MachiavelliTherefore it is unnecessary for a prince to have all the good qualities I have enumerated, but it is very necessary to appear to have them.
Niccolo MachiavelliA prince who is not himself wise cannot be wisely advised. . . . Good advice depends on the shrewdness of the prince who seeks it, and not the shrewdness of the prince on good advice.
Niccolo MachiavelliOne can generally say this about men: that they are ungrateful, fickle, simulators and deceivers, avoiders of danger, greedy for gain; and while you work for their good they are completely yours, offering you their blood, their property, their lives, and their sons when danger is far away; but when it comes nearer to you, they turn away.
Niccolo MachiavelliIt makes him contemptible to be considered fickle, frivolous, effeminate, mean-spirited, irresolute, from all of which a prince should guard himself as from a rock; and he should endeavour to show in his actions greatness, courage, gravity, and fortitude; and in his private dealings with his subjects let him show that his judgments are irrevocable, and maintain himself in such reputation that no one can hope either to deceive him or to get round him.
