A prince must be prudent enough to know how to escape the bad reputation of those vices that would lose the state for him, and must protect himself from those that will not lose it for him, if this is possible; but if he cannot, he need not concern himself unduly if he ignores these less serious vices.
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.
