that this latter religion proceeds from the same mentality as the former, that it is made up of the same superstitions and rests upon the same errors? This is how the theoretical importance which has sometimes been attributed to primitive religions has come to pass as a sign of a systematic hostility to all religion, which, by prejudging the results of the study, vitiates them in advance.
There is no occasion for asking here whether or not there are scholars who have merited this reproach, and who have made religious history and ethnology a weapon against religion. In any case, a sociologist cannot hold such a point of view. In fact, it is an essential postulate of sociology that a human institution cannot rest upon an error and a lie, without which it could not exist. If it were not founded in the nature of things, it would have encountered in the facts a resistance over which it could never have triumphed. So when we commence the study of primitive religions, it is with the assurance that they hold to reality and express it; this principle will be seen to re-enter again and again in the course of the analyses and discussions which follow, and the reproach which we make against the schools from which we have separated ourselves is that they have ignored it. When only the letter of the formulæ is considered, these religious beliefs and practices undoubtedly seem disconcerting at times, and one is tempted to attribute them to some sort of a deep-rooted error. But one must know how to go underneath the symbol to the reality which it represents and which gives it its meaning. The most barbarous and the most fantastic rites and the strangest myths translate some human need, some aspect of life, either individual or social. The reasons with which the faithful justify them may be, and generally are, erroneous; but the true reasons do not cease to exist, and it is the duty of science to discover them.
In reality, then, there are no religions which are false. All are true in their own fashion; all answer, though in different ways, to the given conditions of human existence. It is undeniably possible to arrange them in a hierarchy. Some can be called superior to others, in the sense that they call into play higher mental functions, that they are richer in ideas and sentiments, that they contain more concepts with fewer sensations and images, and that their arrangement is wiser. But howsoever real this greater complexity and this higher ideality may be, they are not sufficient to place the corresponding religions in different classes. All are religions equally, just as all living beings are equally alive, from the most humble plastids up to man. So when we turn to primitive religions it is not with the idea of depreciating religion in general, for these religions are no less respectable than the others. They respond to the same needs, they play the same rôle, they depend upon the same causes; they can also well serve to show the nature of the religious life, and consequently to resolve the problem which we wish to study.
But why give them a sort of prerogative? Why choose them in preference to all others as the subject of our study?—It is merely for reasons of method.
In the first place, we cannot arrive at an understanding of the most recent religions except by following the manner in which they have been progressively composed in history. In fact, historical analysis is the only means of explanation which it is possible to apply to them. It alone enables us to resolve an institution into its constituent elements, for it shows them to us as they are born in time, one after another. On the other hand, by placing every one of them in the condition where it was born, it puts into our hands the only means we have of determining the causes which gave rise to it. Every time that we undertake to explain something human, taken at a given moment in history—be it a religious belief, a moral precept, a legal principle, an æsthetic style or an economic system—it is necessary to commence by going back to its most primitive and simple form, to try to account for the characteristics by which it was marked at that time, and then to show how it developed and became complicated little by little, and how it became that which it is at the moment in question. One readily understands the importance which the determination of the point of departure has for this series of progressive explanations, for all the others are attached to it. It was one of Descartes's principles that the first ring has a predominating place in the chain of scientific truths. But there is no question of placing at the foundation of the science of religions an idea elaborated after the cartesian manner, that is to say, a logical concept, a pure possibility, constructed simply by force of thought. What we must find is a concrete reality, and historical and ethnological observation alone can reveal that to us. But even if this cardinal conception is obtained by a different process than that of Descartes, it remains true that it is destined to have a considerable influence on the whole series of propositions which the science establishes. Biological evolution has been conceived quite differently ever since it has been known that monocellular beings do exist. In the same way, the arrangement of religious facts is explained quite differently, according as we put naturism, animism or some other religious form at the beginning of the evolution. Even the most specialized scholars, if they are unwilling to confine themselves to a task of pure erudition, and if they desire to interpret the facts which they analyse, are obliged to choose one of these hypotheses, and make it their starting-point. Whether they desire it or not, the questions which they raise necessarily take the following form: how has naturism or animism been led to take this particular form, here or there, or to enrich itself or impoverish itself in such and such a fashion? Since it is impossible to avoid taking sides on this initial problem, and since the solution given is destined to affect the whole science, it must be attacked at the outset: that is what we propose to do.
Besides this, outside of these indirect reactions, the study of primitive religions has of itself an immediate interest which is of primary importance.
If it is useful to know what a certain particular religion consists in, it is still more important to know what religion in general is. This is the problem which has aroused the interest of philosophers in all times; and not without reason, for it is of interest to all humanity. Unfortunately, the method which they generally employ is purely dialectic: they confine themselves to analysing the idea which they make for themselves of religion, except as they illustrate the results of this mental analysis by examples borrowed from the religions which best realize their ideal. But even if this method ought to be abandoned, the problem remains intact, and the great service of philosophy is to have prevented its being suppressed by the disdain of scholars. Now it is possible to attack it in a different way. Since all religions can be compared to each other, and since all are species of the same class, there are necessarily many elements which are common to all. We do not mean to speak simply of the outward and visible characteristics which they all have equally, and which make it possible to give them a provisional definition from the very outset of our researches; the discovery of these apparent signs is relatively easy, for the observation which it demands does not go beneath the surface of things. But these external resemblances suppose others which are profound. At the foundation of all systems of beliefs and of all cults there ought necessarily to be a certain number of fundamental representations or conceptions and of ritual attitudes which, in spite of the diversity of forms which they have taken, have the same objective significance and fulfil the same functions everywhere. These are the permanent elements which constitute that which is permanent and human in religion; they form all the objective contents of the idea which is expressed when one speaks of religion in general. How is it possible to pick them out?
Surely it is not by observing the complex religions which appear in the course of history. Every one of these is made up of such a variety of elements that it is very difficult to distinguish what is secondary from what is principal, the essential from the accessory. Suppose that the religion considered is like that of Egypt, India or the classical antiquity. It is a confused mass of many cults, varying according to the locality, the temples, the generations, the dynasties, the invasions, etc. Popular superstitions are there confused with the purest dogmas. Neither the thought nor the activity of the religion is evenly distributed among the believers; according to the men, the environment and the circumstances, the beliefs as well as the rites are thought of in different ways. Here they are priests, there they are monks, elsewhere they are laymen; there are mystics and rationalists, theologians and prophets, etc. In these conditions it is difficult to see what is common to all. In one or another of these systems it is quite possible to find the means of making a profitable study of some particular fact which is specially developed there, such as sacrifice
