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 MachiavelliIf you only notice human proceedings, you may observe that all who attain great power and riches, make use of either force or fraud; and what they have acquired either by deceit or violence, in order to conceal the disgraceful methods of attainment, they endeavor to sanctify with the false title of honest gains.
Niccolo MachiavelliAnyone who becomes master of a city accustomed to freedom and does not destroy it may expect to be destroyed by it; for such a city may always justify rebellion in the name of liberty and its ancient institutions.
