being who has once familiarized himself with the notion of artifice. I was present recently among some members of the lower classes at the flowing of an intermittent spring; not one of them was inclined to believe the phenomenon a natural one, they regarded it as an effect of some mechanism, of some artifice. The same belief is evidently common among primitive people, with this difference, that artificial, instead of suggesting mechanics, implies the notion of a superhuman and marvelous power. [Sidenote: Fetichism a logical theory to primitive man.] Just as the animal finds the rationale of all things in a notion of life and of activity, man tends to find a rationale of all things in a conception of art and of scheming intelligence. For the one, surprising phenomena are simply inexplicable conduct; for the other, they are the complex effects of deliberative intelligence, they are master-pieces. But the notion of activity, far from becoming effaced in the progress of evolution, becomes simply more definite and more precise. Given his incomplete experience, primitive man is perfectly logical in attributing intelligence and consciousness to nature, he could not rationally do otherwise; his mind is imprisoned in a blind alley, and superstition is the sole outlet. At a given moment in human evolution, superstition was perfectly rational. [Sidenote: Seeming immanence of conscious life in nature.] Even in our days, men of science are greatly embarrassed by their inability to point out the precise line of demarcation between the animate and the inanimate; and how should primitive man have grappled with this problem? How distinguish, for example, between sleep and death during one entire portion of life; during sleep, living bodies lie inert, and why should not inert bodies sometimes prove to be alive? At night especially, the whole becomes transformed, everything becomes animate, a breath of wind suffices to make everything palpitate; it seems as if all nature awakened after its day’s sleep; it is the hour when wild beasts go in search of prey, and mysterious noises fill the forest. The calmest imagination, under such circumstances, yields to a temptation to see fantastic objects that are not. One night I was walking on the sea-shore, and saw distinctly a gigantic beast moving some distance away; it proved to be a perfectly motionless rock, in the midst of others like it, but the waves, which alternately covered and discovered it in part, lent it, to my eyes, some portion of their own mobility. How many things in nature borrow thus from some circumstance—from the wind, from a more or less uncertain light—an appearance of life![28] Even when the eyes themselves would be incapable of self-deception, the influence of the foolish terrors so frequent among children and beings habituated to savage life would count enormously. Emotional susceptibility is the more highly developed among savages, in that it forms for them frequently a means of safety.
