This scientific supernaturalism concerns itself with mortal life, not with immortality as do some of the other aspects of the _genre_. It is concrete in its effects, not spiritual. Its incursions into futurity are earthly, not of heaven or hell, and its problems are of time, not of eternity. The form shows how clear, cold intelligence plays with miracles and applies the supernatural to daily life. The enthusiasm, wild and exaggerated in some ways, that sprang up over the prospects of what modern science and investigation would almost immediately do for the world in the latter half of the nineteenth century, had no more interesting effect than in the stimulating of scientific fictive supernaturalism. And though mankind has learned that science will not immediately bring the millennium, science still exercises a strong power over fiction. This type shows a strange effect of realism in supernaturalism, because of the scientific methods, for supernaturalism imposed on material things produces an effect of verisimilitude not gained in the realm of pure spirit. Too intellectually cold for the purposes of poetry, too abstract and elusive for presentation in drama, and too removed by its association with the fantastic aspects of investigation and the curiosities of science to be very appropriate for tragedy, which has hitherto been the chief medium of expressing the dramatic supernatural, science finds its fitting expression in prose fiction. It is an illustration of the widening range of the supernatural in fiction and as such is significant. CHAPTER VIII Conclusion
