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.
I hold it to be of great prudence for men to abstain from threats and insulting words towards any one, for neither the one nor the other in any way diminishes the strength of the enemy; but the one makes him more cautious, and the other increases his hatred of you, and makes him more persevering in his efforts to injure you
Nevertheless, he must be cautious in believing and acting, and must not inspire fear of his own accord, and must proceed in a temperate manner with prudence and humanity, so that too much confidence does not render him incautious, and too much diffidence does not render him intolerant. From this arises the question whether it is better to be loved more than feared, or feared more than loved.
There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things.
For as laws are necessary that good manners may be preserved, so there is need of good manner that laws may be maintained.
[It., Perche, cosi come i buoni costumi, per mantenersi, hanno bisogno delli leggi; cosi le leggi per ossevarsi, hanno bisogno de' buoni costumi.]
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.
I don't doubt that every prince would like to be both; but since it is hard to accomodate these qualities, if you have to make a choice, to be feared is much safer than to be loved. For it is a good general rule about men, that they are ungrateful, fickle, liars, and deceivers, fearful of danger and greedy for gain....[love] is a link of obligation which men, because they are rotten, will break anything they think doing so serves their advantage; but fear involves dread of punishment, from which they can never escape.
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.
Men ought either to be well treated or crushed, because they can avenge themselves of lighter injuries, of more serious ones they cannot; therefore the injury that is to be done to a man ought to be of such a kind that one does not stand in fear of revenge.
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.
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.
