One can say this in general of men: they are ungrateful, disloyal, insincere and deceitful, timid of danger and avid of profit...Love is a bond of obligation that these miserable creatures break whenever it suits them to do so; but fear holds them fast by a dread of punishment that never passes.
In order not to annul our free will, I judge it true that Fortune may be mistress of one half our actions but then even she leaves the other half, or almost, under our control.
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.
A wise man ought always to follow the paths beaten by great men, and to imitate those who have been supreme, so that if his ability does not equal theirs, at least it will savor of it. Let him act like the clever archers who, designing to hit the mark which yet appears too far distant, and knowing the limits to which the strength of their bow attains, take aim much higher than the mark, not to reach by their strength or arrow to so great a height, but to be able with the aid of so high an aim to hit the mark they wish to reach.
A prince must not have any objective nor any thought, nor take up any art, other than the art of war and its ordering and discipline; because it is the only art that pertains to him who commands. And it is of such virtue that not only does it maintain those who were born princes, but many times makes men rise to that rank from private station.
Well used are those cruelties (if it is permitted to speak well of evil) that are carried out in a single stroke, done out of necessity to protect oneself, and are not continued but are instead converted into the greatest possible benefits for the subjects. Badly used are those cruelties which. although being few at the outset, grow with the passing time instead of disappearing. Those who follow the first method can remedy their condition with God and with men; the others cannot possibly survive.
A prince... must learn from the fox and the lion... One must be a fox in order to recognize traps, and a lion to frighten off wolves. Those who act simply as lions are stupid. So it follows that a prudent ruler cannot, and must not, honour his word when it places him at a disadvantage and when the reasons for which he made his promise no longer exist.
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.
