Virtue that wavers is not virtue, but vice revolted from itself, and after a while returning. The actions of just and pious men do not darken in their middle course.
Vice is a monster of so frightful mien As to be hated needs but to be seen; Yet seen too oft, familiar with her face, We first endure, then pity, then embrace.
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.
