This observation of the Red Men is a kind of parable representing a part of the purport of the following treatise. The Indians, making a hasty inference from a trivial phenomenon, arrived unawares at a probably correct conclusion, long unknown to civilised science. They connected the Aurora Borealis with electricity, supposing that multitudes of deer in the sky rubbed the sparks out of each other! Meanwhile, even in the last century, a puzzled populace spoke of the phenomenon as 'Lord Derwentwater's Lights.' The cosmic pomp and splendour shone to welcome the loyal Derwentwater into heaven, when he had given his life for his exiled king. Now, my purpose in the earlier portion of this essay is to suggest that certain phenomena of human nature, apparently as trivial as the sparks rubbed out of a deer's hide in a dark night, may indicate, and may be allied to a force or forces, which, like the Aurora Borealis, may shine from one end of the heavens to the other, strangely illumining the darkness of our destiny. Such phenomena science has ignored, as it so long ignored the sparks from the stroked deer-skin, and the attractive power of rubbed amber. These trivial things were not known to be allied to the lightning, or to indicate a force which man could tame and use. But just as the Indians, by a rapid careless inference, attributed the Aurora Borealis to electric influences, so (as anthropology assures us) savages everywhere have inferred the existence of soul or spirit, intelligence that 'Does not know the bond of Time, Nor wear the manacles of Space,' in part from certain apparently trivial phenomena of human faculty. These phenomena, as Mr. Tylor says, 'the great intellectual movement of the last two centuries has simply thrown aside as worthless.'[1] I refer to alleged experiences, merely odd, sporadic, and, for commercial purposes, useless, such as the transference of thought from one mind to another by no known channel of sense, the occurrence of hallucinations which, _prima facie_, correspond coincidentally with unknown events at a distance, all that is called 'second sight,' or 'clairvoyance,' and other things even more obscure. Reasoning on these real or alleged phenomena, and on other quite normal and accepted facts of dream, shadow, sleep, trance, and death, savages have inferred the existence of spirit or soul, exactly as the Indians arrived at the notion of electricity (not so called by them, of course) as the cause of the Aurora Borealis. But, just as the Indians thought that the cosmic lights were caused by the rubbing together of crowded deer in the heavens (a theory quite childishly absurd), so the savage has expressed, in rude fantastic ways, his conclusion as to the existence of spirit. He believes in wandering separable souls of men, surviving death, and he has peopled with his dreams the whole inanimate universe.
