The results of our analysis thus attach themselves to and confirm those attained by MM. Hubert and Mauss when they studied magic directly.[1186] They have shown that this is nothing more nor less than crude industry based on incomplete science. Behind the mechanisms, purely laical in appearance, which are used by the magician, they point out a background of religious conceptions and a whole world of forces, the idea of which has been taken by magic from religion. We are now able to understand how it comes that magic is so full of religious elements: it is because it was born of religion.

But the principle which has just been set forth does not merely have a function in the ritual; it is of direct interest for the theory of knowledge. In fact, it is a concrete statement of the law of causality and, in all probability, one of the most primitive statements of it which has ever existed. A full conception of the causal relation is implied in the power thus attributed to the like to produce the like; and this conception dominates primitive thought, for it is the basis both of the practices of the cult and the technique of the magician. So the origins of the precept upon which the imitative rites depend are able to clarify those of the principle of causality. The genesis of one should aid us in understanding the genesis of the other. Now we have shown how the former is a product of social causes: it was elaborated by groups having collective ends in view, and it translates collective sentiments. So we may assume that the same is true for the second.

In fact, an analysis of the principle of causality is sufficient to assure us that the diverse elements of which it is composed really did have this origin.

The first thing which is implied in the notion of the causal relation is the idea of efficacy, of productive power, of active force. By cause we ordinarily mean something capable of producing a certain change. The cause is the force before it has shown the power which is in it; the effect is this same power, only actualized. Men have always thought of causality in dynamic terms. Of course certain philosophers had refused all objective value to this conception; they see in it only an arbitrary construction of the imagination, which corresponds to nothing in the things themselves. But, at present, we have no need of asking whether it is founded in reality or not; it is enough for us to state that it exists and that it constitutes and always has constituted an element of ordinary mentality; and this is recognized even by those who criticize it. Our immediate purpose is to seek, not what it may be worth logically, but how it is to be explained.

Now it depends upon social causes. Our analysis of facts has already enabled us to see that the prototype of the idea of force was the mana, wakan, orenda, the totemic principle or any of the various names given to collective force objectified and projected into things.[1187] The first power which men have thought of as such seems to have been that exercised by humanity over its members. Thus reason confirms the results of observation; in fact, it is even possible to show why this notion of power, efficacy or active force could not have come from any other source.

In the first place, it is evident and recognized by all that it could not be furnished to us by external experience. Our senses only enable us to perceive phenomena which coexist or which follow one another, but nothing perceived by them could give us the idea of this determining and compelling action which is characteristic of what we call a power or force. They can touch only realized and known conditions, each separate from the others; the internal process uniting these conditions escapes them. Nothing that we learn could possibly suggest to us the idea of what an influence or efficaciousness is. It is for this very reason that the philosophers of empiricism have regarded these different conceptions as so many mythological aberrations. But even supposing that they all are hallucinations, it is still necessary to show how they originated.

If external experience counts for nothing in the origin of these ideas, and it is equally inadmissible that they were given us ready-made, one might suppose that they come from internal experience. In fact, the notion of force obviously includes many spiritual elements which could only have been taken from our psychic life.

Some have believed that the act by which our will brings a deliberation to a close, restrains our impulses and commands our organism, might have served as the model of this construction. In willing, it is said, we perceive ourselves directly as a power in action. So when this idea had once occurred to men, it seems that they only had to extend it to things to establish the conception of force.

As long as the animist theory passed as a demonstrated truth, this explanation was able to appear to be confirmed by history. If the forces with which human thought primitively populated the world really had been spirits, that is to say, personal and conscious beings more or less similar to men, it was actually possible to believe that our individual experience was enough to furnish us with the constituent elements of the notion of force. But we know that the first forces which men imagined were, on the contrary, anonymous, vague and diffused powers which resemble cosmic forces in their impersonality, and which are therefore most sharply contrasted with the eminently personal power, the human will. So it is impossible that they should have been conceived in its image.
