Certainly virtue is like precious odors, most fragrant when they are incensed, or crushed: for prosperity doth best discover vice, but adversity doth best discover virtue.
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.
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.
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.
