No one, whether he be wise or foolish, bad or good, if asked to choose between these two kinds of men, will ever be found to withhold praise from what deserves praise, or blame from what is to be blamed. And yet almost all, deceived by a false good and a false glory, allow themselves either ignorantly or wilfully to follow in the footsteps such as deserve blame rather than praise; and, have it in their power to establish, to their lasting renown, a commonwealth or kingdom, turn aside to create a tyranny without a thought how much they thereby lose in name, fame, security, tranquility, and peace of mind; and into how much infamy, scorn, danger, and disquiet they run. But were they to read history, and turn to profit the lessons of the past, it seems impossible that those living in a republic as private citizens, should not prefer, in their native city, to play the part of Scipio rather of Caesar; or that those who by good fortune or merit have risen to be rulers, should not seek rather to resemble Agesilaus, Timoleon, and Dion, than to Nabis, Phalaris and Dionysius; since they would see how the latter are loaded with infamy, while the former have been extolled beyond bounds. They would see, too, how Timoleon and others like him, had as great authority in their country as Dionysius or Phalaris in theirs, while enjoying far greater security. Nor let anyone finding Caesar celebrated by a crowd of writers, be misled by his glory; for those who praise him have been corrupted by his good fortune, and overawed by the greatness of that empire which, being governed in his name, would not suffer any to speak their minds openly concerning him. But let him who desires to know how historians would have written of Caesar had they been free to declare their thoughts mark what they say of Catiline, than whom Caesar is more hateful, in proportion as he who does is more to be condemned than he who only desires to do evil. Let him see also what praises they lavish upon Brutus, because being unable, out of respect for his power, to reproach Caesar, they magnify his enemy. And if he who has become prince in any state will but reflect, how, after Rome was made an empire, far greater praise was earned those emperors who lived within the laws, and worthily, than by those who lived in the contrary way, he will see that Titus, Nerva, Trajan, Hadrian, Antoninus and Marcus had no need of praetorian cohorts, or of countless legions to guard them, but were defended by their own good lives, the goodwill of their subjects, and the attachment of the senate. In like manner he will perceive in the case of Caligula, Nero, Vitellius, and ever so many more of those evil emperors, that all the armies of the east and of the west were of no avail to protect them from the enemies whom their bad and depraved lives raised up against them. And were the history of these emperors rightly studied, it would be a sufficient lesson to any prince how to distinguish the paths which lead to honour and safety from those which end in shame and insecurity. For of the twenty-six emperors from Caesar to Maximinus, sixteen came to a violent, ten only to a natural death; and though one or two of those who died by violence may have been good princes, as Galba or Pertinax, they met their fate in consequence of that corruption which their predecessors had left behind in the army. And if among those who died a natural death, there be found some bad emperors, like Severus, it is to be ascribed to their signal good fortune and to their great abilities, advantages seldom found united in the same man. From the study of this history we may also learn how a good government is to be established; for while all the emperors who succeeded to the throne by birth, except Titus, were bad, all were good who succeeded by adoption; as in the case of the five from Nerva to Marcus. But so soon as the empire fell once more to the heirs by birth, its ruin recommenced.
Let a prince therefore look to that period which extends from Nerva to Marcus, and contrast it with that which went before and that which came after, and then let him say in which of them he would wish to have been born or to have reigned. For during these times in which good men governed, he will see the prince secure in the midst of happy subjects, and the whole world filled with peace and justice. He will find the senate maintaining its authority, the magistrates enjoying their honours, rich citizens their wealth, rank and merit held in respect, ease and content everywhere prevailing, rancour, licence, corruption and ambition everywhere quenched, and that golden age restored in which every one might hold and support what opinions he pleased. He will see, in short, the world triumphing, the sovereign honoured and revered, the people animated with love, and rejoicing in their security. But should he turn to examine the times of
