Quotes from Aristotle and Machiavelli

Aristotle first (343 B.C.):

"A tyrant must put on the appearance of uncommon devotion to religion. Subjects are less apprehensive of illegal treatment from a ruler whom they consider to be God-fearing and pious."

Machiavelli, about a millenium later:

A prince, then, must be very careful not to say a word which does not seem inspired by the five qualities I mentioned earlier. To those seeing and hearing him, he should appear a man of compassion, a man of good faith, a man of integrity, a kind and a religious man. And there is nothing so important as to seem to have this last quality. Men in general judge by their eyes rather than by their hands; because everyone is in a position to watch, few are in a position to come in close touch with you. Everyone sees what you appear to be, few experience what you really are. And those few dare not gainsay the many who are backed by the majesty of the state. In the actions of all men, and especially of princes, where there is no court of appeal, one judges by the result.
