“It is absolutely necessary, for the peace and safety of mankind, that some of earth's dark, dead corners and unplumbed depths be left alone; lest sleeping abnormalities wake to resurgent life, and blasphemously surviving nightmares squirm and splash out of their black lairs to newer and wider conquests.”

“I have an odd craving to whisper about those few frightful hours in that ill-rumoured and evilly shadowed seaport of death and blasphemous abnormality.”

“The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age. ”

“Any magazine-cover hack can splash paint around wildly and call it a nightmare, or a witches sabbath or a portrait of the devil; but only a great painter can make such a thing really scare or ring true. That's because only a real artist knows the anatomy of the terrible, or the physiology of fear.”

“It might, too, have been the singular cold that alienated me; for such chilliness was abnormal on so hot a day, and the abnormal always excites aversion, distrust, and fear.”

“Yet when I looked from that highest of all gable windows, looked while the candles sputtered and the insane viol howled with the night-wind, I saw no city spread below, and no friendly lights gleamed from remembered streets, but only the blackness of space illimitable; unimagined space alive with motion and music, and having no semblance of anything on earth. And as I stood there looking in terror, the wind blew out both the candles in that ancient peaked garret, leaving me in savage and impenetrable darkness with chaos and pandemonium before me, and the demon madness of that night-baying viol behind me.”
