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.
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.
I don't doubt that every prince would like to be both; but since it is hard to accomodate these qualities, if you have to make a choice, to be feared is much safer than to be loved. For it is a good general rule about men, that they are ungrateful, fickle, liars, and deceivers, fearful of danger and greedy for gain....[love] is a link of obligation which men, because they are rotten, will break anything they think doing so serves their advantage; but fear involves dread of punishment, from which they can never escape.
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.
Thus it is well to seem merciful, faithful, humane, sincere, religious, and also to be so; but you must have the mind so disposed that when it is needful to be otherwise you may be able to change to the opposite qualities.
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.
I consider it a mark of great prudence in a man to abstain from threats or any contemptuous expressions, for neither of these weaken the enemy, but threats make him more cautious, and the other excites his hatred, and a desire to revenge himself.
