For it must be noted, that men must either be caressed or else annihilated; they will revenge themselves for small injuries, but cannot do so for great ones; the injury therefore that we do to a man must be such that we need not fear his vengeance.
Niccolo MachiavelliA prince, therefore, must not mind incurring the charge of cruelty for the purpose of keeping his subjects united and confident; for, with a very few examples, he will be more merciful than those who, from excess of tenderness, allow disorders to arise, from whence spring murders and rapine; for these as a rule injure the whole community, while the executions carried out by the prince injure only one individual. And of all princes, it is impossible for a new prince to escape the name of cruel, new states being always full of dangers.
Niccolo MachiavelliBesides what has been said, people are fickle by nature; and it is a simple to convince them of something but difficult to hold them in that conviction; and, therefore, affairs should be managed in such a way that when they no longer believe, they can be made to believe by force.
Niccolo MachiavelliThere is nothing more difficult to plan, more doubtful of success, nor more dangerous to manage than the creation of a new order of things..... Whenever his enemies have occasion to attack the innovator they do so with the passion of partisans, while the others defend him sluggishly so that the innovator and his party alike are vulnerable.
