Besides 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 MachiavelliAny man who tries to be good all the time is bound to come to ruin among the great number who are not good. Hence a prince who wants to keep his authority must learn how not to be good, and use that knowledge, or refrain from using it, as necessity requires.
Niccolo MachiavelliTherefore it is unnecessary for a prince to have all the good qualities I have enumerated, but it is very necessary to appear to have them.
