The Complete Essays of H. P. Lovecraft

Atmosphere, not action, is the great desideratum of weird fiction.

Each weird story—to speak more particularly of the horror type—seems to involve five definite elements: (a) some basic, underlying horror or abnormality—condition, entity, etc.—, (b) the general effects or bearings of the horror, (c) the mode of manifestation—object embodying the horror and phenomena observed—, (d) the types of fear-reaction pertaining to the horror, and (e) the specific effects of the horror in relation to the given set of conditions.

I think, four distinct types of weird story; one expressing a mood or feeling, another expressing a pictorial conception, a third expressing a general situation, condition, legend, or intellectual conception, and a fourth explaining a definite tableau or specific dramatic situation or climax. In another way, weird tales may be grouped into two rough categories—those in which the marvel or horror concerns some condition or phenomenon, and those in which it concerns some action of persons in connexion with a bizarre condition or phenomenon.

There will always be a small percentage of persons who feel a burning curiosity about unknown outer space, and a burning desire to escape from the prison-house of the known and the real into those enchanted lands of incredible adventure and infinite possibilities which dreams open up to us, and which things like deep woods, fantastic urban towers, and flaming sunsets momentarily suggest. These persons include great authors as well as insignificant amateurs like myself—Dunsany, Poe, Arthur Machen, M. R. James, Algernon Blackwood, and Walter de la Mare being typical masters in this field.

My reason for writing stories is to give myself the satisfaction of visualising more clearly and detailedly and stably the vague, elusive, fragmentary impressions of wonder, beauty, and adventurous expectancy which are conveyed to me by certain sights (scenic, architectural, atmospheric, etc.), ideas, occurrences, and images encountered in art and literature.
