Any man who tries to be good all the time is bound to come to ruin among the great number who are not good. Hence a prince who wants to keep his authority must learn how not to be good, and use that knowledge, or refrain from using it, as necessity requires.
A prudent man should always follow in the path trodden by great men and imitate those who are most excellent, so that if he does not attain to their greatness, at any rate he will get some tinge of it.
There is nothing more difficult to plan, more doubtful of success, nor more dangerous to manage than the creation of a new order of things..... Whenever his enemies have occasion to attack the innovator they do so with the passion of partisans, while the others defend him sluggishly so that the innovator and his party alike are vulnerable.
An armed republic submits less easily to the rule of one of its citizens than a republic armed by foreign forces. Rome and Sparta were for many centuries well armed and free. The Swiss are well armed and enjoy great freedom. Among other evils caused by being disarmed, it renders you contemptible. It is not reasonable to suppose that one who is armed will obey willingly one who is unarmed; or that any unarmed man will remain safe among armed servants.
The reason is that nature has so created men that they are able to desire everything but are not able to attain everything: so that the desire being always greater than the acquisition, there results discontent with the possession and little satisfaction to themselves from it. From this arises the changes in their fortunes; for as men desire, some to have more, some in fear of losing their acquisition, there ensues enmity and war, from which results the ruin of that province and the elevation of another.
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.
....it cannot be called ingenuity to kill one's fellow citizens, to betray friends, to be without faith, without mercy, without religion; by these means one can aquire power but not glory.
Thus it happens in matters of state; for knowing afar off (which it is only given a prudent man to do) the evils that are brewing, they are easily cured. But when, for want of such knowledge, they are allowed to grow so that everyone can recognize them, there is no longer any remedy to be found.
He who becomes a Prince through the favour of the people should always keep on good terms with them; which it is easy for him to do, since all they ask is not to be oppressed
Men are less hesitant about harming someone who makes himself loved than one who makes himself feared because love is held together by a chain of obligation which, since men are wretched creatures, is broken on every occasion in which their own interests are concerned; but fear is sustained by dread of punishment which will never abandon you.
Men seldom rise from low condition to high rank without employing either force or fraud, unless that rank should be attained either by gift or inheritance.
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.
