When one looks close one is surprised to see how many causes would naturally lead one to attribute life, and life of an extraordinary and mysterious character, to such and such really passive objects. Such causes act evidently with greatly additional power upon the savage, the primitive man, the man of the quaternary epoch, or upon the anthropoid, as yet undiscovered, whose instruments have been found in the tertiary period. Common animals, in effect, are almost lacking in attention; from which it results that to produce any durable mental effect on them, a prolonged repetition of the same sensation is necessary; they must be accustomed to it. Moreover their crude intelligence takes no impression from evanescent facts, they are unacquainted with the external world except by averages. Exceptional facts strike them for an instant, but presently glance off into oblivion. In this imperfect machine, wear and tear is very rapid and the traces of phenomena inevitably blur and become confounded. If animals possess a memory for sensations, they lack an intellectual memory altogether; they are capable of surprise, but not of remembering a surprise. To produce in them a tenacious memory demands a setting of pain or pleasure, and even then, if they recollect the sensation they experienced, they readily forget the grounds of it. They feel passively, instead of observing. From the moment where, with man, the spirit of observation enters upon the scene everything is different; an exceptional fact, for the same reason that it becomes rapidly effaced in an animal intelligence, penetrates the more deeply into the memory of a man. Moreover, man’s sphere of action is much wider than that of any animal, and consequently the field of his experience is much more vast; the more he modifies, voluntarily, the face of nature, the more capable he becomes of recognizing and observing the variations which it presents, independently of his interventions. Man possesses a notion unknown to animals, the notion of _artificial_ things, of results deliberately attained by self-conscious volition. One remembers that _fetich_ comes from _factitius_, artificial. Man, being acquainted with the use of fire, will regard, for example, a forest set ablaze by lightning from entirely a different point of view from what any animal could: the animal will flee without any other sentiment than that of alarm; the man will naturally suppose the existence of some person who set it on fire—who was acting, who was doing on a grand scale what he himself sometimes does. Similarly with a boiling spring; this phenomenon lies too far beyond the limits of animal intelligence to be especially striking; but a man, on the other hand, who habitually goes to some trouble to provide himself with boiling water, infers the existence of some subterranean person who is heating water for purposes of his own. All natural phenomena tend thus to appear artificial to the eyes of a
