To the problem thus stated, two contrary solutions have been given.
There is no religious system, ancient or recent, where one does not meet, under different forms, two religions, as it were, side by side, which, though being united closely and mutually penetrating each other, do not cease, nevertheless, to be distinct. The one addresses itself to the phenomena of nature, either the great cosmic forces, such as winds, rivers, stars or the sky, etc., or else the objects of various sorts which cover the surface of the earth, such as plants, animals, rocks, etc.; for this reason it has been given the name of naturism. The other has spiritual beings as its object, spirits, souls, geniuses, demons, divinities properly so-called, animated and conscious agents like man, but distinguished from him, nevertheless, by the nature of their powers and especially by the peculiar characteristic that they do not affect the senses in the same way: ordinarily they are not visible to human eyes. This religion of spirits is called animism. Now, to explain the universal co-existence of these two sorts of cults, two contradictory theories have been proposed. For some, animism is the primitive religion, of which naturism is only a secondary and derived form. For the others, on the contrary, it is the nature cult which was the point of departure for religious evolution; the cult of spirits is only a peculiar case of that.
These two theories are, up to the present, the only ones by which the attempt has been made to explain rationally93 the origins of religious thought. Thus the capital problem raised by the history of religions is generally reduced to asking which of these two solutions should be chosen, or whether it is not better to combine them, and in that case, what place must be given to each of the two elements.94 Even those scholars who do not admit either of these hypotheses in their systematic form, do not refuse to retain certain propositions upon which they rest.95 Thus we have a certain number of theories already made, which must be submitted to criticism before we take up the study of the facts for ourselves. It will be better understood how indispensable it is to attempt a new one, when we have seen the insufficiency of these traditional conceptions.

It is Tylor who formed the animist theory in its essential outlines.96 Spencer, who took it up after him, did not reproduce it without introducing certain modifications.97 But in general the questions are posed by each in the same terms, and the solutions accepted are, with a single exception, identically the same. Therefore we can unite these two doctrines in the exposition which follows, if we mark, at the proper moment, the place where the two diverge from one another.
In order to find the elementary form of the religious life in these animistic beliefs and practices, three desiderata must be satisfied: first, since according to this hypothesis, the idea of the soul is the cardinal idea of religion, it must be shown how this is formed without taking any of its elements from an anterior religion; secondly, it must be made clear how souls become the object of a cult and are transformed into spirits; and thirdly and finally, since the cult of these spirits is not all of any religion, it remains to be explained how the cult of nature is derived from it.
According to this theory, the idea of the soul was first suggested to men by the badly understood spectacle of the double life they ordinarily lead, on the one hand, when awake, on the other, when asleep. In fact, for the savage,98 the mental representations which he has while awake and those of his dreams are said to be of the same value: he objectifies the second like the first, that is to say, that he sees in them the images of external objects whose appearance they more or less accurately reproduce. So when he dreams that he has visited a distant country, he believes that he really was there. But he could not have gone there, unless two beings exist within him: the one, his body, which has remained lying on the ground and which he finds in the same position on awakening; the other, during this time, has travelled through space. Similarly, if he seems to talk with one of his companions who he knows was really at a distance, he concludes that the other also is composed of two beings: one which sleeps at a distance, and another which has come to manifest himself by means of the dream. From these repeated experiences, he little by little arrives at the idea that each of us has a double, another self, which in determined conditions has the power of leaving the organism where it resides and of going roaming at a distance.
Of course, this double reproduces all the essential traits of the perceptible being which serves it as external covering; but at the same time it is distinguished from this by many characteristics. It is more active, since it can cover vast distances in an instant. It is more malleable and plastic; for, to leave the body, it must pass out by its apertures, especially the mouth and nose. It is represented as made of matter, undoubtedly, but of a matter much more subtile and etherial than any which we know empirically. This double is the soul. In fact, it cannot be doubted that in numerous societies the soul has been conceived in the image of the body; it is believed that it reproduces even the accidental deformities such as those resulting from wounds or mutilations. Certain Australians, after having killed their enemy, cut off his right thumb, so that his soul, deprived of its thumb also, cannot throw a javelin and revenge itself. But while it resembles the body, it has, at the same time, something half spiritual about it. They say that "it is the finer or more aeriform part of the body," that "it has no flesh nor bone nor sinew"; that when one wishes to take hold of it, he feels nothing; that it is "like a purified body."99
Also, other facts of experience which affect the mind in the same way naturally group themselves around this fundamental fact taught by the dream: fainting, apoplexy, catalepsy, ecstasy, in a word, all cases of temporary insensibility. In fact, they all are explained very well by the hypothesis that the principle of life and feeling is able to leave the body momentarily. Also, it is natural that this principle should be confounded with the double, since the absence of the double during sleep daily has the effect of suspending thought and life. Thus diverse observations seem to agree mutually and to confirm the idea of the constitutional duality of man.100
But the soul is not a spirit. It is attached to a body which it can leave only by exception; in so far as it is nothing more than that, it is not the object of any cult. The spirit, on the other hand, though generally having some special thing as its residence, can go away at will, and a man can enter into relations with it only by observing ritual precautions. The soul can become a spirit, then, only by transforming itself: the simple application of these preceding ideas to the fact of death produced this metamorphosis quite naturally. For a rudimentary intelligence, in fact, death is not distinguished from a long fainting swoon or a prolonged sleep; it has all their aspects. Thus it seems that it too consists in a separation of the soul and the body, analogous to that produced every night; but as in such cases, the body is not reanimated, the idea is formed of a separation without an assignable limit of time. When the body is once destroyed — and funeral rites have the object of hastening this destruction — the separation is taken as final. Hence come spirits detached from any organism and left free in space. As their number augments with time, a population of souls forms around the living population. These souls of men have the needs and passions of men; they seek to concern themselves with the life of their companions of yesterday, either to aid them or to injure them, according to the sentiments which they have kept towards them. According to the circumstances, their nature makes them either very precious auxiliaries or very redoubtable adversaries. Owing to their extreme fluidity, they can even enter into the body, and cause all sorts of disorders there, or else increase its vitality. Thus comes the habit of attributing to them all those events of life which vary slightly from the ordinary: there are very few of these for which they cannot account. Thus they constitute a sort of ever-ready supply of causes which never leaves one at a loss when in search of explanations. Does a man appear
