And now have I not told you that what you mistake for madness is but overacuteness of the senses?
Edgar Allan PoeTHE thousand injuries of Fortunato I had borne as I best could, but when he ventured upon insult I vowed revenge. You, who so well know the nature of my soul, will not suppose, however, that gave utterance to a threat. At length I would be avenged; this was a point definitely, settled --but the very definitiveness with which it was resolved precluded the idea of risk. I must not only punish but punish with impunity. A wrong is unredressed when retribution overtakes its redresser. It is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong.
Edgar Allan PoeThe sole purpose is to provide infinite springs, at which the soul may allay the eternal thirst TO KNOW which is forever unquenchable within it, since to quench it, would be to extinguish the soul's self.
