This jealousy, then, is so natural to princes, that they cannot guard themselves against it, nor show gratitude to those who serving under their standard have gained great victories and made great conquests on their behalf. And if it be impossible for princes to free their minds from such suspicions, there is nothing strange or surprising that a people should be unable to do so. For as a city living under free institutions has two ends always before it, namely to acquire liberty and to preserve it, it must of necessity be led by its excessive passion for liberty to make mistakes in the pursuit of both these objects. Of the mistakes it commits in the effort to acquire liberty, I shall speak, hereafter, in the proper place. Of mistakes committed in the endeavour to preserve liberty are to be noted, the injuring those citizens who ought to be rewarded, and the suspecting those who should be trusted. Now, although in a State which has grown corrupt these errors occasion great evils, and commonly lead to a tyranny, as happened in Rome when Caesar took by force what ingratitude had denied him, they are nevertheless the cause of much good in the republic which has not been corrupted, since they prolong the duration of its free institutions, and make men, through fear of punishment, better and less ambitious. Of all peoples possessed of great power, the Romans, for the reasons I have given, have undoubtedly been the least ungrateful, since we have no other instance of their ingratitude to cite, save that of Scipio. For both Coriolanus and Camillus were banished on account of the wrongs which they inflicted on the commons; and though the former was not forgiven because he constantly retained ill will against the people, the latter was not only recalled, but for the rest of his life honoured as a prince. But the ingratitude shown towards Scipio arose from the suspicion wherewith the citizens came to regard him, which they had not felt in the case of the others, and which was occasioned by the greatness of the enemy whom he had overthrown, the fame he had won by prevailing in so dangerous and protracted a war, the suddenness of his victories, and, finally, the favour which his youth, together with his prudence and his other memorable qualities had gained for him. These qualities were, in truth, so remarkable that the very magistrates, not
