But to exercise the intellect the prince should read histories, and study there the actions of illustrious men, to see how they have borne themselves in war, to examine the causes of their victories and defeat, so as to avoid the latter and imitate the former; and above all do as an illustrious man did, who took as an exemplar one who had been praised and famous before him, and whose achievements and deeds he always kept in his mind, as it is said Alexander the Great imitated Achilles, Caesar Alexander, Scipio Cyrus. And whoever reads the life of Cyrus, written by Xenophon, will recognize afterwards in the life of Scipio how that imitation was his glory, and how in chastity, affability, humanity, and liberality Scipio conformed to those things which have been written of Cyrus by Xenophon. A wise prince ought to observe some such rules, and never in peaceful times stand idle, but increase his resources with industry in such a way that they may be available to him in adversity, so that if fortune chances it may find him prepared to resist her blows. CHAPTER XV. CONCERNING THINGS FOR WHICH MEN, AND ESPECIALLY PRINCES, ARE PRAISED OR BLAMED It remains now to see what ought to be the rules of conduct for a prince towards subject and friends. And as I know that many have written on this point, I expect I shall be considered presumptuous in mentioning it again, especially as in discussing it I shall depart from the methods of other people. But, it being my intention to write a thing which shall be useful to him who apprehends it, it appears to me more appropriate to follow up the real truth of the matter than the imagination of it; for many have pictured republics and principalities which in fact have never been known or seen, because how one lives is so far distant from how one ought to live, that he who neglects what is done for what ought to be done, sooner effects his ruin than his preservation; for a man who wishes to act entirely up to his professions of virtue soon meets with what destroys him among so much that is evil.
