A prudent man... must behave like those archers who, if they are skillful, when the target seems too distant, know the capabilities of their bow and aim a good deal higher than their objective, not in order to shoot so high but so that by aiming high they can reach the target.
Whoever takes it upon himself to establish a commonwealth and prescribe laws must presuppose all men naturally bad, and that they will yield to their innate evil passions as often as they can do so with safety.
Rome remained free for four hundred years and Sparta eight hundred, although their citizens were armed all that time; but many other states that have been disarmed have lost their liberties in less than forty years.
Entrepreneurs are simply those who understand that there is little difference between obstacle and opportunity and are able to turn both to their advantage.
And what physicians say about disease is applicable here: that at the beginning a disease is easy to cure but difficult to diagnose; but as time passes, not having been recognized or treated at the outset, it becomes easy to diagnose but difficult to cure. The same thing occurs in affairs of state; for by recognizing from afar the diseases that are spreading in the state (which is a gift given only to the prudent ruler), they can be cured quickly; but when, not having been recognized, they are not recognized and are left to grow to the extent that everyone recognizes them, there is no longer any cure.
One can make this generalization about men: they are ungrateful, fickle, liars, and deceivers, they shun danger and are greedy for profit; while you treat them well, they are yours. They would shed their blood for you, risk their property, their lives, their children, so long, as I said above, as danger is remote; but when you are in danger they turn against you.
Men never do good unless necessity drives them to it; but when they are free to choose and can do just as they please, confusion and disorder become rampant.
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 need trouble little about conspiracies when the people are well disposed, but when they are hostile and hold him in hatred, then he must fear everything and everybody.
Whoever wishes to foresee the future must consult the past; for human events ever resemble those of preceding times. This arises from the fact that they are produced by men who ever have been, and ever shall be, animated by the same passions, and thus they necessarily have the same results.
