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.

There are horrors beyond life's edge that we do not suspect, and once in a while man's evil prying calls them just within our range.

The oldest and strongest emotion of mankind is fear.

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.

The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown

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.

Vigorous let us be in attaining our ends, and mild in our method of attainment.
