in general?
Things are quite different in the lower societies. The slighter development of individuality, the small extension of the group, the homogeneity of external circumstances, all contribute to reducing the differences and variations to a minimum. The group has an intellectual and moral conformity of which we find but rare examples in the more advanced societies. Everything is common to all. Movements are stereotyped; everybody performs the same ones in the same circumstances, and this conformity of conduct only translates the conformity of thought. Every mind being drawn into the same eddy, the individual type nearly confounds itself with that of the race. And while all is uniform, all is simple as well. Nothing is deformed like these myths, all composed of one and the same theme which is endlessly repeated, or like these rites made up of a small number of gestures repeated again and again. Neither the popular imagination nor that of the priests has had either the time or the means of refining and transforming the original substance of the religious ideas and practices; these are shown in all their nudity, and offer themselves to an examination, it requiring only the slightest effort to lay them open. That which is accessory or secondary, the development of luxury, has not yet come to hide the principal elements.2 All is reduced to that which is indispensable, to that without which there could be no religion. But that which is indispensable is also that which is essential, that is to say, that which we must know before all else.
Primitive civilizations offer privileged cases, then, because they are simple cases. That is why, in all fields of human activity, the observations of ethnologists have frequently been veritable revelations, which have renewed the study of human institutions. For example, before the middle of the nineteenth century, everybody was convinced that the father was the essential element of the family; no one had dreamed that there could be a family organization of which the paternal authority was not the keystone. But the discovery of Bachofen came and upset this old conception. Up to very recent times it was regarded as evident that the moral and legal relations of kindred were only another aspect of the psychological relations which result from a common descent; Bachofen and his successors, MacLennan, Morgan and many others still laboured under this misunderstanding. But since we have become acquainted with the nature of the primitive clan, we know that, on the contrary, relationships cannot be explained by consanguinity. To return to religions, the study of only the most familiar ones had led men to believe for a long time that the idea of god was characteristic of everything that is religious. Now the religion which we are going to study presently is, in a large part, foreign to all idea of divinity; the forces to which the rites are there addressed are very different from those which occupy the leading place in our modern religions, yet they aid us in understanding these latter forces. So nothing is more unjust than the disdain with which too many historians still regard the work of ethnographers. Indeed, it is certain that ethnology has frequently brought about the most fruitful revolutions in the different branches of sociology. It is for this same reason that the discovery of unicellular beings, of which we just spoke, has transformed the current idea of life. Since in these very simple beings, life is reduced to its essential traits, these are less easily misunderstood.
But primitive religions do not merely aid us in disengaging the constituent elements of religion; they also have the great advantage that they facilitate the explanation of it. Since the facts there are simpler, the relations between them are more apparent. The reasons with which men account for their acts have not yet been elaborated and denatured by studied reflection; they are nearer and more closely related to the motives which have really determined these acts. In order to understand an hallucination perfectly, and give it its most appropriate treatment, a physician must know its original point of departure. Now this event is proportionately easier to find if he can observe it near its beginnings. The longer the disease is allowed to develop, the more it evades observation; that is because all sorts of interpretations have intervened as it advanced, which tend to force the original state into the background, and across which it is frequently difficult to find the initial one. Between a systematized hallucination and the first impressions which gave it birth, the distance is often considerable. It is the same thing with religious thought. In proportion as it progresses in history, the causes which called it into existence, though remaining active, are no longer perceived, except across a vast scheme of interpretations which quite transform them. Popular mythologies and subtile theologies have done their work: they have superimposed upon the primitive sentiments others which are quite different, and which, though holding to the first, of which they are an elaborated form, only allow their true nature to appear very imperfectly. The psychological gap between the cause and the effect, between the apparent cause and the effective cause, has become more considerable and more difficult for the mind to leap. The remainder of this book will be an illustration and a verification of this remark on method. It will be seen how, in the primitive religions, the religious fact still visibly carries the mark of its origins: it would have been well-nigh impossible to infer them merely from the study of the more developed religions.
The study which we are undertaking is therefore a way of taking up again, but under new conditions, the old problem of the origin of religion. To be sure, if by origin we are to understand the very first beginning, the question has nothing scientific about it, and should be resolutely discarded. There was no given moment when religion began to exist, and there is consequently no need of finding a means of transporting ourselves thither in thought. Like every human institution, religion did not commence anywhere. Therefore, all speculations of this sort are justly discredited; they can only consist in subjective and arbitrary constructions which are subject to no sort of control. But the problem which we raise is quite another one. What we want to do is to find a means of discerning the ever-present causes upon which the most essential forms of religious thought and practice depend. Now for the reasons which were just set forth, these causes are proportionately more easily observable as the societies where they are observed are less complicated. That is why we try to get as near as possible to the origins.3 It is not that we ascribe particular virtues to the lower religions. On the contrary, they are rudimentary and gross; we cannot make of them a sort of model which later religions only have to reproduce. But even their grossness makes them instructive, for they thus become convenient for experiments, as in them, the facts and their relations are easily seen. In order to discover the laws of the phenomena which he studies, the physicist tries to simplify these latter and rid them of their secondary characteristics. For that which concerns institutions, nature spontaneously makes the same sort of simplifications at the beginning of history. We merely wish to put these to profit. Undoubtedly we can only touch very elementary facts by this method. When we shall have accounted for them as far as possible, the novelties of every sort which have been produced in the course of evolution will not yet be explained. But while we do not dream of denying the importance of the problems thus raised, we think that they will profit by being treated in their turn, and that it is important to take them up only after those of which we are going to undertake the study at present.

But our study is not of interest merely for the science of religion. In fact, every religion has one side by which it overlaps the circle of properly religious ideas, and there, the study of religious phenomena gives a means of renewing the problems which, up to the present, have only been discussed among philosophers.
For a long time it has been known that the first systems of representations with which men have pictured to themselves the world and themselves were of religious origin. There is no religion that is not a cosmology at the same time that it is a speculation upon divine things. If philosophy and the sciences were born of religion, it is because religion began by taking the place of the sciences and philosophy. But it has been less frequently noticed that religion has not confined itself to enriching the human intellect, formed beforehand, with a certain number of ideas; it has contributed to forming the intellect itself. Men owe to it not only a good part of the substance of their knowledge, but also the form in which this knowledge has been elaborated.
At the roots of all our judgments there are a certain number of essential ideas which dominate all our intellectual life; they are what philosophers since Aristotle
