How could we safely approach him maintaining our order? If we wished to retire, what ought we to do? If they retired, how should we follow them? And he put before them as they went along all the cases that might happen to an army, heard their opinion, gave his own, fortifying it by argument; so that through these continued cogitations there could never happen any incident when leading his armies for which he was not prepared. But as to exercise for the mind, the prince ought to read history and study the actions of eminent men, see how they acted in warfare, examine the causes of their victories and losses in order to imitate the former and avoid the latter, and above all, do as some eminent men have done in the past, who have imitated some one, who has been much praised and glorified, and have always kept their deeds and actions before them, as they say Alexander the Great imitated Achilles, Caesar Alexander, and Scipio Cyrus. And whoever reads the life of Cyrus written by Xenophon, will perceive in the life of Scipio how gloriously he imitated him, and how, in chastity, affability, humanity, and liberality Scipio conformed to those qualities of Cyrus described by Xenophon.
A wise prince should follow similar methods and never remain idle in peaceful times, but by industry make such good use of the time as may serve him in adversity, so that when fortune changes she may find him prepared to resist her blows.
