I am firmly convinced, therefore, that to set up a republic which is to last a long time, the way to set about it is to constitute it as Sparta and Venice were constituted; to place it in a strong position, and so to fortify it that no one will dream of taking it by a sudden assault; and, on the other hand, not to make it so large as to appear formidable to its neighbors. It should in this way be able to enjoy its form of government for a long time. For war is made on a commonwealth for two reasons: to subjugate it, and for fear of being subjugated by it.
One can say this in general of men: they are ungrateful, disloyal, insincere and deceitful, timid of danger and avid of profit...Love is a bond of obligation that these miserable creatures break whenever it suits them to do so; but fear holds them fast by a dread of punishment that never passes.
The reply is, that one ought to be both feared and loved, but as it is difficult for the two to go together, it is much safer to be feared than loved, if one of the two has to be wanting. For it may be said of men in general that they are ungrateful, voluble, dissemblers, anxious to avoid danger, and covetous of gain; as long as you benefit them, they are entirely yours; they offer you their blood, their goods, their life, and their children, as I have before said, when the necessity is remote; but when it approaches, they revolt.
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.
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.
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.
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.
Entrepreneurs are simply those who understand that there is little difference between obstacle and opportunity and are able to turn both to their advantage.
A prince must not have any other object nor any other thought… but war, its institutions, and its discipline; because that is the only art befitting one who commands.
