War should be the only study of a prince. He should consider peace only as a breathing-time, which gives him leisure to contrive, and furnishes as ability to execute, military plans.
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.
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 are of three different capacities: one understands intuitively; another understands so far as it is explained; and a third understands neither of himself nor by explanation. The first is excellent, the second, commendable, and the third, altogether useless.
From the latter he is defended by being well armed and having good allies, and if he is well armed he will have good friends, and affairs will always remain quiet within when they are quiet without, unless they should have been already disturbed by conspiracy; and even should affairs outside be disturbed, if he has carried out his preparations and has lived as I have said, as long as he does not despair, he will resist every attack.
Many have dreamed up republics and principalities that have never in truth been known to exist; the gulf between how one should live and how one does live is so wide that a man who neglects what is actually done for what should be done learns the way to self-destruction rather than self-preservation.
Where the very safety of the country depends upon the resolution to be taken, no consideration of justice or injustice, humanity or cruelty, nor of glory or of shame, should be allowed to prevail. But putting all other considerations aside, the only question should be: What course will save the life and liberty of the country?
Decide which is the line of conduct that presents the fewest drawbacks and then follow it out as being the best one, because one never finds anything perfectly pure and unmixed, or exempt from danger.
I desire to go to Hell and not to Heaven. In the former I shall enjoy the company of popes, kings and princes, while in the latter are only beggars, monks and apostles
It is a true observation of ancient writers, that as men are apt to be cast down by adversity, so they, are easily satiated with prosperity, and that joy and grief produce the same effects. For whenever men are not obliged by necessity to fight they fight from ambition, which is so powerful a passion in the human breast that however high we reach we are never satisfied.
You know better than I that in a Republic talent is always suspect. A man attains an elevated position only when his mediocrity prevents him from being a threat to others. And for this reason a democracy is never governed by the most competent, but rather by those whose insignificance will not jeopardize anyone else's self-esteem.
I believe that it is possible for one to praise, without concern, any man after he is dead since every reason and supervision for adulation is lacking.
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.
