When we seek to know why this was, several reasons present themselves, the first being that men so passionately love change, that, commonly speaking, those who are well off are as eager for it as those who are badly off:  for as already has been said with truth, men are pampered by prosperity, soured by adversity.  This love of change, therefore, makes them open the door to any one who puts himself at the head of new movements in their country, and if he be a foreigner they adopt his cause, if a fellow-countryman they gather round him and become his partisans and supporters; so that whatever methods he may there use, he will succeed in making great progress.  Moreover, men being moved by two chief passions, love and fear, he who makes himself feared commands with no less authority than he who makes himself loved; nay, as a rule, is followed and obeyed more implicitly than the other.  It matters little, however, which of these two ways a captain chooses to follow, provided he be of transcendent valour, and has thereby won for himself a great name For when, like Hannibal or Scipio, a man is very valiant, this quality will cloak any error he may commit in seeking either to be too much loved or too much feared.  Yet from each of these two tendencies, grave mischiefs, and such as lead to the ruin of a prince, may arise.  For he who would be greatly loved, if he swerve ever so little from the right road, becomes contemptible; while he who would be greatly feared, if he go a jot too far, incurs hatred.  And since it is impossible, our nature not allowing it, to adhere to the exact mean, it is essential that any excess should be balanced by an exceeding valour, as it was in Hannibal and Scipio.  And yet we find that even they, while they were exalted by the methods they followed, were also injured by them.  How they were exalted has been shown.  The injury which Scipio suffered was, that in Spain his soldiers, in concert with certain of his allies, rose against him, for no other reason than that they stood in no fear of him.  For men are so restless, that if ever so small a door be opened to their ambition, they forthwith forget all the love they have borne their prince in return for his graciousness and goodness, as did these soldiers and allies of Scipio; when, to correct the mischief, he was forced to use something of a cruelty foreign to his nature.

As to Hannibal, we cannot point to any particular instance wherein his cruelty or want of faith are seen to have been directly hurtful to him; but we may well believe that Naples and other towns which remained loyal to the Roman people, did so by reason of the dread which his character inspired.  This, however, is abundantly clear, that his inhumanity made him more detested by the Romans than any other enemy they ever had; so that while to Pyrrhus, in Italy with his army, they gave up the traitor who offered to poison him, Hannibal, even when disarmed and a fugitive, they never forgave, until they had compassed his death.
