It was necessary, therefore, to Moses that he should find the people of Israel in Egypt enslaved and oppressed by the Egyptians, in order that they should be disposed to follow him so as to be delivered out of bondage. It was necessary that Romulus should not remain in Alba, and that he should be abandoned at his birth, in order that he should become King of Rome and founder of the fatherland. It was necessary that Cyrus should find the Persians discontented with the government of the Medes, and the Medes soft and effeminate through their long peace. Theseus could not have shown his ability had he not found the Athenians dispersed. These opportunities, therefore, made those men fortunate, and their high ability enabled them to recognize the opportunity whereby their country was ennobled and made famous. Those who by valorous ways become princes, like these men, acquire a principality with difficulty, but they keep it with ease. The difficulties they have in acquiring it rise in part from the new rules and methods which they are forced to introduce to establish their government and its security. And it ought to be remembered that there is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things, because the innovator has for enemies all those who have done well under the old conditions, and lukewarm defenders in those who may do well under the new. This coolness arises partly from fear of the opponents, who have the laws on their side, and partly from the incredulity of men, who do not readily believe in new things until they have had a long experience of them. Thus it happens that whenever those who are hostile have the opportunity to attack they do it like partisans, whilst the others defend lukewarmly, in such wise that the prince is endangered along with them. It is necessary, therefore, if we desire to discuss this matter thoroughly, to inquire whether these innovators can rely on themselves or have to depend on others: that is to say, whether, to consummate their enterprise, have they to use prayers or can they use force? In the first instance they always succeed badly, and never compass anything; but when they can rely on themselves and use force, then they are rarely endangered. Hence it is that all armed prophets have conquered, and the unarmed ones have been destroyed. Besides the reasons mentioned, the nature of the people is variable, and whilst it is easy to persuade them, it is difficult to fix them in that persuasion. And thus it is necessary to take such measures that, when they believe no longer, it may be possible to make them believe by force.
