A prince being thus obliged to know well how to act as a beast must imitate the fox and the lion, for the lion cannot protect himself from snares, and the fox cannot defend himself from wolves.
A prince... must learn from the fox and the lion... One must be a fox in order to recognize traps, and a lion to frighten off wolves. Those who act simply as lions are stupid. So it follows that a prudent ruler cannot, and must not, honour his word when it places him at a disadvantage and when the reasons for which he made his promise no longer exist.
In truth, there never was any remarkable lawgiver amongst any people who did not resort to divine authority, as otherwise his laws would not have been accepted by the people; for there are many good laws, the importance of which is known to be the sagacious lawgiver, but the reasons for which are not sufficiently evident to enable him to persuade others to submit to them; and therefore do wise men, for the purpose of removing this difficulty, resort to divine authority.
And here one must not that hatred is acquired just as much by means of good actions as by bad ones; and so, as I said above, if a prince wishes to maintain the state, he is often obliged not to be good; because whenever that group which you believe you need to support you is corrupted, whether it be the common people, the soldiers, or the nobles, it is to your advantage to follow their inclinations in order to satisfy them; and then good actions are your enemy.
Knowing how to fight made men more bold, because no one fears doing what it seems to him he has learned to do. Therefore, the ancients wanted their citizens to be trained in every warlike action.
He who desires or attempts to reform the government of a state and wishes to have it accepted, must at least retain the semblance of the old forms; so that it may seem to the people that there has been no change in the institutions, even though in fact they are entirely different from the old ones. For the great majority of mankind are satisfied with appearances, as though they were realities.
And it will always happen that he who is not your friend will request your neutrality and he who is your friend will ask you to declare yourself by taking up arms. And irresolute princes, in order to avoid present dangers, follow the neutral road most of the time, and most of the time they are ruined.
the wise man should always follow the roads that have been trodden by the great, and imitate those who have most excelled, so that if he cannot reach their perfection, he may at least acquire something of its savour.
If you only notice human proceedings, you may observe that all who attain great power and riches, make use of either force or fraud; and what they have acquired either by deceit or violence, in order to conceal the disgraceful methods of attainment, they endeavor to sanctify with the false title of honest gains.
If someone puts up the argument that King Louis gave the Romagna to Pope Alexander, and the kingdom of Naples to Spain, in order to avoid a war, I would answer as I did before: that you should never let things get out of hand in order to avoid war. You don't avoid such a war, you merely postpone it, to your own disadvantage.
