Minds are of three kinds: one is capable of thinking for itself; another is able to understand the thinking of others; and a third can neither think for itself nor understand the thinking of others. The first is of the highest excellence, the second is excellent, and the third is worthless.
A prudent man... must behave like those archers who, if they are skillful, when the target seems too distant, know the capabilities of their bow and aim a good deal higher than their objective, not in order to shoot so high but so that by aiming high they can reach the target.
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.
He who has not first laid his foundations may be able with great ability to lay them afterwards, but they will be laid with trouble to the architect and danger to the building.
One can make this generalization about men: they are ungrateful, fickle, liars, and deceivers, they shun danger and are greedy for profit; while you treat them well, they are yours. They would shed their blood for you, risk their property, their lives, their children, so long, as I said above, as danger is remote; but when you are in danger they turn against you.
People should either be caressed or crushed. If you do them minor damage they will get their revenge; but if you cripple them there is nothing they can do. If you need to injure someone, do it in such a way that you do not have to fear their vengeance.
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.
The lion cannot protect himself from traps, and the fox cannot defend himself from wolves. One must therefore be a fox to recognize traps, and a lion to frighten wolves.
A return to first principles in a republic is sometimes caused by the simple virtues of one man. His good example has such an influence that the good men strive to imitate him, and the wicked are ashamed to lead a life so contrary to his example.
