The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown. These facts few psychologists will dispute, and their admitted truth must establish for all time the genuineness and dignity of the weirdly horrible tale as a literary form. Against it are discharged all the shafts of a materialistic sophistication which clings to frequently felt emotions and external events, and of a naively insipid idealism which deprecates the æsthetic motive and calls for a didactic literature to “uplift” the reader toward a suitable degree of smirking optimism. But in spite of all this opposition the weird tale has survived, developed, and attained remarkable heights of perfection; founded as it is on a profound and elementary principle whose appeal, if not always universal, must necessarily be poignant and permanent to minds of the requisite sensitiveness.
The appeal of the spectrally macabre is generally narrow because it demands from the reader a certain degree of imagination and a capacity for detachment from everyday life. Relatively few are free enough from the spell of the daily routine to respond to rappings from outside, and tales of ordinary feelings and events, or of common sentimental distortions of such feelings and events, will always take first place in the taste of the majority; rightly, perhaps, since of course these ordinary matters make up the greater part of human experience. But the sensitive are always with us, and sometimes a curious streak of fancy invades an obscure corner of the very hardest head; so that no amount of rationalisation, reform, or Freudian analysis can quite annul the thrill of the chimney-corner whisper or the lonely wood. There is here involved a psychological pattern or tradition as real and as deeply grounded in mental experience as any other pattern or tradition of mankind; coeval with the religious feeling and closely related to many aspects of it, and too much a part of our inmost biological heritage to lose keen potency over a very important, though not numerically great, minority of our species.
Man’s first instincts and emotions formed his response to the environment in which he found himself. Definite feelings based on pleasure and pain grew up around the phenomena whose causes and effects he understood, whilst around those which he did not understand—and the universe teemed with them in the early days—were naturally woven such personifications, marvelous interpretations, and sensations of awe and fear as would be hit upon by a race having few and simple ideas and limited experience. The unknown, being likewise the unpredictable, became for our primitive forefathers a terrible and omnipotent source of boons and calamities visited upon mankind for cryptic and wholly extra-terrestrial reasons, and thus clearly belonging to spheres of existence whereof we know nothing and wherein
