A man who wishes to make a profession of goodness in everything must necessarily come to grief among so many who are not good. Therefore, it is necessary for a prince, who wishes to maintain himself, to learn how not to be good, and to use this knowledge and not use it according to the necessity of the case.
Niccolo MachiavelliI 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.
Niccolo MachiavelliMinds 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.
Niccolo MachiavelliI am firmly convinced, therefore, that to set up a republic which is to last a long time, the way to set about it is to constitute it as Sparta and Venice were constituted; to place it in a strong position, and so to fortify it that no one will dream of taking it by a sudden assault; and, on the other hand, not to make it so large as to appear formidable to its neighbors. It should in this way be able to enjoy its form of government for a long time. For war is made on a commonwealth for two reasons: to subjugate it, and for fear of being subjugated by it.
