Nature creates few men brave, industry and training makes many.

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 may second fortune, but they cannot thwart her.

It is necessary that the prince should know how to color his nature well, and how to be a hypocrite and dissembler. For men are so simple, and yield so much to immediate necessity, that the deceiver will never lack dupes.

They have not any difficulties on the way up because they fly, but they have many when they reach the summit.

There is nothing that Nature seems to have inclined us to as much as society.

Always assume incompetence before looking for conspiracy.
