That prince is highly esteemed who conveys this impression of himself, and he who is highly esteemed is not easily conspired against; for, provided it is well known that he is an excellent man and revered by his people, he can only be attacked with difficulty.
For as laws are necessary that good manners may be preserved, so there is need of good manner that laws may be maintained.
