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.
The Romans never allowed a trouble spot to remain simply to avoid going to war over it, because they knew that wars don't just go away, they are only postponed to someone else's advantage. Therefore, they made war with Philip and Antiochus in Greece, in order not to have to fight them in Italy... They never went by that saying which you constantly hear from the wiseacres of our day, that time heals all things. They trusted rather their own character and prudence- knowing perfectly well that time contains the seeds of all things, good as well as bad.
Then also pretexts for seizing property are never wanting, and one who begins to live by rapine will always find some reason for taking the goods of others, whereas causes for taking life are rarer and more quickly destroyed.
Therefore, in order not to have to rob his subjects, to be able to defend himself, not to become poor and contemptible, and not to be forced to become rapacious, a prince must consider it of little importance if he incurs the name of miser, for this is one of the vices that permits him to rule.
All courses of action are risky, so prudence is not in avoiding danger (it's impossible), but calculating risk and acting decisively. Make mistakes of ambition and not mistakes of sloth. Develop the strength to do bold things, not the strength to suffer.
No proceeding is better than that which you have concealed from the enemy until the time you have executed it. To know how to recognize an opportunity in war, and take it, benefits you more than anything else. Nature creates few men brave, industry and training makes many. Discipline in war counts more than fury.
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.
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.
People should either be caressed or crushed. If you do them minor damage they will get their revenge; but if you cripple them there is nothing they can do. If you need to injure someone, do it in such a way that you do not have to fear their vengeance.
States that rise quickly, just as all the other things of nature that are born and grow rapidly, cannot have roots and ramifications; the first bad weather kills them
Therefore the best fortress is to be found in the love of the people, for although you may have fortresses they will not save you if you are hated by the people.
