“A certain atmosphere of breathless and unexplainable dread of outer, unknown forces must be present; and there must be a hint, expressed with a seriousness and portentousness becoming its subject, of that most terrible conception of the human brain - a malign and particular suspension or defeat of those laws of Nature which are our only safeguard against the assaults of chaos and the daemons of unplumbed space .... Therefore we must judge a weird tale not by the author's intent, or by the mere mechanics of the plot; but by the emotional level which it attains at its least mundane point... The one test of the really weird is simply this - whether or not there be excited in the reader a profound sense of dread, and of contact with unknown spheres and powers; a subtle attitude of awed listening, as if for the beating of black wings or the scratching of outside shapes and entities on the known universe's utmost rim.”

“The one test of the really weird (story) is simply this--whether or not there be excited in the reader a profound sense of dread, and of contact with unknown spheres and powers; a subtle attitude of awed listening, as if for the beating of black wings or the scratching of outside shapes and entities on the known universe's utmost rim.”

“A serious adult story must be true to something in life. Since marvel tales cannot be true to the events of life, they must shift their emphasis towards something to which they can be true; namely, certain wistful or restless moods of the human spirit, wherein it seeks to weave gossamer ladders of escape from the galling tyranny of time, space, and natural law.”

“Now all my tales are based on the fundemental premise that common human laws and interests and emotions have no validity or significance in the vast cosmos-at-large.... To achieve the essence of real externality, whether of time or space or dimension, one must forget that such things as organic life, good and evil, love and hate, and all such local attributes of a negligible and temporary race called mankind, have any existence at all.”

“Life is a hideous thing, and from the background behind what we know of it peer daemoniacal hints of truth which make it sometimes a thousandfold more hideous. Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species—if separate species we be—for its reserve of unguessed horrors could never be borne by mortal brains if loosed upon the world.”

“It was just a colour out of space—a frightful messenger from unformed realms of infinity beyond all Nature as we know it; from realms whose mere existence stuns the brain and numbs us with the black extra-cosmic gulfs it throws open before our frenzied eyes.”

“We might have known from the first that human curiosity is undying, and that the results we announced would be enough to spear others ahead on the same age-long pursuit of the unknown.”
