But according to the statement of Spencer, these accessory causes had only a secondary influence; that which principally determined the institution of naturism was "the literal interpretation of metaphorical names."106
We had to mention this theory to have our exposition of animism complete; but it is too inadequate for the facts, and too universally abandoned to-day to demand that we stop any longer for it. In order to explain a fact as general as the religion of nature by an illusion, it would be necessary that the illusion invoked should have causes of an equal generality. Now even if misunderstandings, such as those of which Spencer gives some rare illustrations, could explain the transformation of the cult of ancestors into that of nature, it is not clear why this should be produced with a sort of universality. No psychical mechanism necessitated it. It is true that because of its ambiguity, the word might lead to an equivocation; but on the other hand, all the personal souvenirs left by the ancestor in the memories of men should oppose this confusion. Why should the tradition which represented the ancestor such as he really was, that is to say, as a man who led the life of a man, everywhere give way before the prestige of a word? Likewise, one should have a little difficulty in admitting that men were born of a mountain or a star, of an animal or a plant; the idea of a similar exception to the ordinary conceptions of generation could not fail to raise active resistance. Thus, it is far from true that the error found a road all prepared before it, but rather, all sorts of reasons should have kept it from being accepted. It is difficult to understand how, in spite of all these obstacles, it could have triumphed so generally.
II
The theory of Tylor, whose authority is always great, still remains. His hypotheses on the dream and the origin of the ideas of the soul and of spirits are still classic; it is necessary, therefore, to test their value.
First of all, it should be recognized that the theorists of animism have rendered an important service to the science of religions, and even to the general history of ideas, by submitting the idea of the soul to historical analysis. Instead of following so many philosophers and making it a simple and immediate object of consciousness, they have much more correctly viewed it as a complex whole, a product of history and mythology. It cannot be doubted that it is something essentially religious in its nature, origin and functions. It is from religion that the philosophers received it; it is impossible to understand the form in which it is represented by the thinkers of antiquity, if one does not take into account the mythical elements which served in its formation.
But if Tylor has had the merit of raising this problem, the solution he gives raises grave difficulties.
First of all, there are reservations to be made in regard to the very principle which is at the basis of this theory. It is taken for granted that the soul is entirely distinct from the body, that it is its double, and that within it or outside of it, it normally lives its own autonomous life. Now we shall see107 that this conception is not that of the primitive, or at least, that it only expresses one aspect of his idea of the soul. For him, the soul, though being under certain conditions independent of the organism which it animates, confounds itself with this latter to such an extent that it cannot be radically separated from it: there are organs which are not only its appointed seat, but also its outward form and material manifestation. The notion is therefore more complex than the doctrine supposes, and it is doubtful consequently whether the experiences mentioned are sufficient to account for it; for even if they did enable us to understand how men have come to believe themselves double, they cannot explain how this duality does not exclude, but rather, implies a deeper unity and an intimate interpenetration of the two beings thus differentiated.
But let us admit that the idea of the soul can be reduced to the idea of a double, and then see how this latter came to be formed. It could not have been suggested to men except by the experience of dreams. That they might understand how they could see places more or less distant during sleep, while their bodies remained lying on the ground, it would seem that they were led to conceive of themselves as two beings: on the one hand, the body, and on the other, a second self, able to leave the organism in which it lives and to roam about in space. But if this hypothesis of a double is to be able to impose itself upon men with a sort of necessity, it should be the only one possible, or at least, the most economical one. Now as a matter of fact, there are more simple ones which, it would seem, might have occurred to the mind just as naturally. For example, why should the sleeper not imagine that while asleep he is able to see things at a distance? To imagine such a power would demand less expense to the imagination than the construction of this complex notion of a double, made of some etherial, semi-invisible substance, and of which direct experience offers no example. But even supposing that certain dreams rather naturally suggest the animistic explanation, there are certainly many others which are absolutely incompatible with it. Often our dreams are concerned with passed events; we see again the things which we saw or did yesterday or the day before or even during our youth, etc.; dreams of this sort are frequent and hold a rather considerable place in our nocturnal life. But the idea of a double cannot account for them. Even if the double can go from one point to another in space, it is not clear how it could possibly go back and forth in time. Howsoever rudimentary his intelligence may be, how could a man on awakening believe that he had really been assisting at or taking part in events which he knows passed long before? How could he imagine that during his sleep he lived a life which he knows has long since gone by? It would be much more natural that he should regard these renewed images as merely what they really are, that is, as souvenirs like those which he has during the day, but ones of a special intensity.
Moreover, in the scenes of which we are the actors and witnesses while we sleep, it constantly happens that one of our contemporaries has a rôle as well as ourselves: we think we see and hear him in the same place where we see ourselves. According to the animists, the primitive would explain this by imagining that his double was visited by or met with those of certain of his companions. But it would be enough that on awakening he question them, to find that their experiences do not coincide with his. During this same time, they too have had dreams, but wholly different ones. They have not seen themselves participating in the same scene; they believe that they have visited wholly different places. Since such contradictions should be the rule in these cases, why should they not lead men to believe that there had probably been an error, that they had merely imagined it, that they had been duped by illusions? This blind credulity which is attributed to the primitive is really too simple. It is not true that he must objectify all his sensations. He cannot live long without perceiving that even when awake his senses sometimes deceive him. Then why should he believe them more infallible at night than during the day? Thus we find that there are many reasons opposing the theory that he takes his dreams for the reality and interprets them by means of a double of himself.
But more than that, even if every dream were well explained by the hypothesis of a double, and could not be explained otherwise, it would remain a question why men have attempted to explain them. Dreams undoubtedly constitute the matter of a possible problem. But we pass by problems every day which we do not raise, and of which we have no suspicion until some circumstance makes us feel the necessity of raising them. Even when the taste for pure speculation is aroused, reflection is far from raising all the problems to which it could eventually apply itself; only those attract it which present a particular interest. Especially, when it is a question of facts which always take place in the same manner, habit easily numbs curiosity, and we do not even dream of questioning them. To shake off this torpor, it is necessary that practical exigencies, or at least a very pressing theoretical interest, stimulate our attention and turn it in this direction. That is why, at every moment of history, there have been so many things that we have not tried to understand, without even being conscious of our renunciation. Up until very recent times, it was believed that the sun was only a few feet in diameter. There is something incomprehensible in the statement that a luminous disc of such slight dimensions could illuminate the world: yet for centuries men never thought of resolving this contradiction. The fact of heredity has been known for a long time, but it is very recently that the attempt has been made
