And hence it comes that a commonwealth endures longer, and has a more sustained good fortune than a princedom, because from the diversity in the characters of its citizens, it can adapt itself better than a prince can to the diversity of times. For, as I have said before, a man accustomed to follow one method, will never alter it; whence it must needs happen that when times change so as no longer to accord with his method, he will be ruined. Piero Soderini, of whom I have already spoken, was guided in all his actions by patience and gentleness, and he and his country prospered while the times were in harmony with these methods. But, afterwards, when a time came when it behoved him to have done with patience and gentleness, he knew not how to drop them, and was ruined together with his country. Pope Julius II., throughout the whole of his pontificate, was governed by impulse and passion, and because the times were in perfect accord, all his undertakings prospered. But had other times come requiring other qualities, he could not have escaped destruction, since he could not have changed his methods nor his habitual line of conduct. As to why such changes are impossible, two reasons may be given. One is that we cannot act in opposition to the bent of our nature. The other, that when a man has been very successful while following a particular method, he can never be convinced that it is for his advantage to try some other. And hence it results that a man’s fortunes vary, because times change and he does not change with them. So, too, with commonwealths, which, as we have already shown at length, are ruined from not altering their institutions to suit the times. And commonwealths are slower to change than princes are, changes costing them more effort; because occasions must be waited for which shall stir the whole community, and it is not enough that a single citizen alters his method of acting. But since I have made mention of Fabius Maximus who wore out Hannibal by keeping him at bay, I think it opportune to consider in the following Chapter whether a general who desires to engage his enemy at all risks, can be prevented by that enemy from doing so. CHAPTER X.—_That a Captain cannot escape Battle when his Enemy forces it on him at all risks._ “_Cneius Sulpitius when appointed dictator against the Gauls, being unwilling to tempt Fortune by attacking an enemy whom delay and a disadvantageous position would every day render weaker, protracted the war._”
