Thus this same idea tends to come to light on every side.[669] The impression becomes more and more prevalent that even the most elementary mythological constructions are secondary products[670] which cover over a system of beliefs, at once simpler and more obscure, vaguer and more essential, which form the solid foundations upon which the religious systems are built. It is this primitive foundation which our analysis of totemism has enabled us to reach. The various writers whose studies we have just mentioned arrived at this conclusion only through facts taken from very diverse religions, some of which even correspond to a civilization that is already far advanced: such is the case, for example, with the Mexican religions, of which Preuss makes great use. So it might be asked if this theory is equally applicable to the most simple religions. But since it is impossible to go lower than totemism, we are not exposed to this risk of error, and at the same time, we have an opportunity of finding the initial notion from which the ideas of wakan and mana are derived: this is the notion of the totemic principle.[671]
But this notion is not only of primary importance because of the rôle it has played in the development of religious ideas; it also has a lay aspect in which it is of interest for the history of scientific thought. It is the first form of the idea of force.
In fact, the wakan plays the same rôle in the world, as the Sioux conceives it, as the one played by the forces with which science explains the diverse phenomena of nature. This, however, does not mean that it is thought of as an exclusively physical energy; on the contrary, in the next chapter we shall see that the elements going to make up this idea are taken from the most diverse realms. But this very compositeness of its nature enables it to be utilized as a universal principle of explanation. It is from it that all life comes;[672] "all life is wakan"; and by this word life, we must understand everything that acts and reacts, that moves and is moved, in both the mineral and biological kingdoms. The wakan is the cause of all the movements which take place in the universe. We have even seen that the orenda of the Iroquois is "the efficient cause of all the phenomena and all the activities which are manifested around men." It is a power "inherent in all bodies and all things."[673] It is the orenda which makes the wind blow, the sun lighten and heat the earth, or animals reproduce and which makes men strong, clever and intelligent. When the Iroquois says that the life of all nature is the product of the conflicts aroused between the unequally intense orenda of the different beings, he only expresses, in his own language, this modern idea that the world is a system of forces limiting and containing each other and making an equilibrium.
