By the delusions of seeming good the people are often misled to desire their own ruin; and they are frequently influenced by great hopes and brave promises.
War should be the only study of a prince. He should consider peace only as a breathing-time, which gives him leisure to contrive, and furnishes as ability to execute, military plans.
Therefore, a prudent ruler ought not to keep faith when by so doing it would be against his interest, and when the reasons which made him bind himself no longer exist. If men were all good, this precept would not be a good one; but as they are bad, and would not observe their faith with you, so you are not bound to keep faith with them.
When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred.
It is often found that modesty and humility not only do no good, but are positively hurtful, when they are shown to the arrogant who have taken up a prejudice against you, either from envy or from any other cause.
There are three kinds of brains: One understands of itself, another can be taught to understand, and the third can neither understand to itself or be taught to understand.
For among other evils caused by being disarmed, it renders you contemptible; which is one of those disgraceful things which a prince must guard against.
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.
One man should not be afraid of improving his posessions, lest they be taken away from him, or another deterred by high taxes from starting a new business. Rather, the Prince should be ready to reward men who want to do these things and those who endeavour in any way to increase the prosperity of their city or their state.
For he who innovates will have for his enemies all those who are well off under the existing order of things, and only lukewarm supporters in those who might be better off under the new.
A prince ought to have no other aim or thought, nor select anything else for his study, than war and its rules and discipline; for this is the sole art that belongs to him who rules, and it is of such force that it not only upholds those who are born princes, but it often enables men to rise from a private station to that rank. And, on the contrary, it is seen that when princes have thought more of ease than of arms they have lost their states. And the first cause of your losing it is to neglect this art; and what enables you to acquire a state is to be master of the art.
For it must be noted, that men must either be caressed or else annihilated; they will revenge themselves for small injuries, but cannot do so for great ones; the injury therefore that we do to a man must be such that we need not fear his vengeance.
Some princes, so as to hold securely the state, have disarmed their subjects, others have kept their subject towns distracted by factions...Our forefathers, and those who were reckoned wise, were accustomed to say that it was necessary to hold Pistoia [an Italian city] by factions and Pisa by fortress, and with this idea they fostered quarrels in some of their tributary towns so as to keep possession of them the more easily.
