Thus the soul is frequently represented in an animal form. It is known that in inferior societies, death is never considered a natural event, due to the action of purely physical causes; it is generally attributed to the evil workings of some sorcerer. In a large number of Australian societies, in order to determine who is the responsible author of this murder, they work on the principle that the soul of the murderer must inevitably come to visit its victim. Therefore, the body is placed upon a scaffolding; then, the ground under the corpse and all around it is carefully smoothed off so that the slightest mark becomes easily perceptible. They return the next day; if an animal has passed by there during the interval, its tracks are readily recognizable. Their form reveals the species to which it belongs, and from that, they infer the social group of which the guilty man is a member. They say that it is a man of such a class or such a clan,[852] according to whether the animal is the totem of this or that class or clan. So the soul is believed to have come in the form of the totemic animal.
In other societies where totemism has weakened or disappeared, the soul still continues to be thought of in an animal form. The natives of Cape Bedford (North Queensland) believe that the child, at the moment of entering the body of its mother, is a curlew if it is a girl, or a snake if it is a boy.[853] It is only later that it takes a human form. Many of the Indians of North America, says the Prince of Wied, say that they have an animal in their bodies.[854] The Bororo of Brazil represent the soul in the form of a bird, and therefore believe that they are birds of the same variety.[855] In other places, it is thought of as a snake, a lizard, a fly, a bee, etc.[856]
But it is especially after death that this animal nature of the soul is manifested. During life, this characteristic is partially veiled, as it were, by the very form of the human body. But when death has once set it free, it becomes itself again. Among the Omaha, in at least two of the Buffalo clans, it is believed that the souls of the dead go to rejoin the buffalo, their ancestors.[857] The Hopi are divided into a certain number of clans, whose ancestors were animals or beings with animal forms. Now Schoolcraft tells us that they say that at death, they take their original form again; each becomes a bear or deer, according to the clan to which he belongs.[858] Very frequently the soul is believed to reincarnate itself in the body of an animal.[859] It is probably from this that the widely-spread doctrine of metempsychosis was derived. We have already seen how hard pressed Tylor is to account for it.[860] If the soul is an essentially human principle, what could be more curious than this marked predilection which it shows, in so large a number of societies, for the animal form? On the other hand, everything is explained if, by its very constitution, the soul is closely related to the animal, for in that case, when it returns to the animal world at the close of this life, it is only returning to its real nature. Thus the generality of the belief in metempsychosis is a new proof that the constituent elements of the idea of the soul have been taken largely from the animal kingdom, as is presupposed by the theory which we have just set forth.
