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.
For as the interposition of a rivulet, however small, will occasion the line of the phalanx to fluctuate, so any trifling disagreement will be the cause of seditions; but they will not so soon flow from anything else as from the disagreement between virtue and vice, and next to that between poverty and riches.
Therefore, in order not to have to rob his subjects, to be able to defend himself, not to become poor and contemptible, and not to be forced to become rapacious, a prince must consider it of little importance if he incurs the name of miser, for this is one of the vices that permits him to rule.
Virtue also depends on ourselves. And so also does vice. For where we are free to act we are also free to refrain from acting, and where we are able to say No we are also able to say Yes; if therefore we are responsible for doing a thing when to do it right, we are also responsible for not doing it when not to do it is wrong, and if we are responsible for rightly not doing a thing, we are also responsible for wrongly doing it.
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.
Sensuality, too, which used to show itself course, smiling, unmasked, and unmistakable, is now serious, analytic, and so burdened with a sense of its responsibilities that it passes muster half the time as a new type of asceticism.
Where virtue is, sensibility is the ornament and becoming attire of virtue. On certain occasions it may almost be said to become virtue. But sensibility and all the amiable qualities may likewise become, and too often have become, the panders of vice and the instruments of seduction.
