Read the following paragraph from "The Black Cat" by Edgar Allen Poe. For the most wild, yet most homely narrative which I am about to pen, I neither expect nor solicit belief. Mad indeed would I be to expect it, in a case where
my very senses reject their own evidence. Yet, mad am I not-and very surely do I not dream. But to-morrow I die, and to-day I would unburden my soul. My
immediate purpose is to place before the world, plainly, succinctly, and without comment, a series of mere household events. In their consequences, these
events have terrified-have tortured-have destroyed me. Yet I will not attempt to expound them. To me, they have presented little but Horror-to many they
will seem less terrible than baroques. Hereafter, perhaps, some intellect may be found which will reduce my phantasm to the common-place-some intellect
more calm, more logical, and far less excitable than my own, which will perceive, in the circumstances I detail with awe, nothing more than an ordinary
succession of very natural causes and effects.
