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.
....for friendships that are acquired by a price and not by greatness and nobility of character are purchased but are not owned, and at the proper moment they cannot be spent.
In the same manner, having been reduced by disorder, and sunk to their utmost state of depression, unable to descend lower, they, of necessity, reascend; and thus from good they gradually decline to evil, and from evil again return to good. The reason is, that valor produces peace; peace, repose; repose, disorder; disorder, ruin; so from disorder order springs; from order virtue, and from this, glory and good fortune.
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.

Whoever takes it upon himself to establish a commonwealth and prescribe laws must presuppose all men naturally bad, and that they will yield to their innate evil passions as often as they can do so with safety.
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.
When settling disputes between his subjects, he should ensure that his judgement is irrevocable; and he should be so regarded that no one ever dreams of trying to deceive or trick him.
