Naturally one would rather be a broad artist with power to evoke beauty from every phase of experience--but when one unmistakably isn't such an artist, there's no sense in bluffing and faking and pretending that one is.
Non- Euclidean calculus and quantum physics are enough to stretch any brain; and when one mixes them with folklore, and tries to trace a strange background of multi-dimensional reality behind the ghoulish hints of Gothic tales and the wild whispers of the chimney-corner, one can hardly expect to be wholly free from mental tension. (Dreams In The Witch-House)
In my actual imaginative contact with life, I am vastly more responsive to beauty than to horror - indeed, I never experience real cosmic horror except in infrequent nightmares. However, when I come to record my various imaginative experiences, I generally find that only the horror items have any uniqueness or originality. Others have seen the same beautiful things that I have seen, & have sung them more nobly.
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.
No one ever wrote a story yet without some real emotional drive behind it--and I have not that drive except where violations of the natural order ... defiances and evasions of time, space, and cosmic law ... are concerned.
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.
There now ensued a series of incidents which transported me to the opposite extremes of ecstasy and horror; incidents which I tremble to recall and dare not seek to interpret.
I am so beastly tired of mankind and the world that nothing can interest me unless it contains a couple of murders on each page or deals with the horrors unnameable and unaccountable that leer down from the external universes.
