The Melanesian attributes this same general efficacy to his mana. It is owing to his mana that a man succeeds in hunting or fighting, that gardens give a good return or that flocks prosper. If an arrow strikes its mark, it is because it is charged with mana; it is the same cause which makes a net catch fish well, or a canoe ride well on the sea,[674] etc. It is true that if certain phrases of Codrington are taken literally, mana should be the cause to which is attributed "everything which is beyond the ordinary power of men, outside the common processes of nature."[675] But from the very examples which he cites, it is quite evident that the sphere of the mana is really much more extended. In reality, it serves to explain usual and everyday phenomena; there is nothing superhuman or supernatural in the fact that a ship sails or a hunter catches game, etc. However, among these events of daily life, there are some so insignificant and familiar that they pass unperceived: they are not noticed and consequently no need is felt of explaining them. The concept of mana is applied only to those that are important enough to cause reflection, and to awaken a minimum of interest and curiosity; but they are not marvellous for all that. And what is true of the mana as well as the orenda and wakan, may be said equally well of the totemic principle. It is through this that the life of the men of the clan and the animals or plants of the totemic species, as well as all the things which are classified under the totem and partake of its nature, is manifested.
So the idea of force is of religious origin. It is from religion that it has been borrowed, first by philosophy, then by the sciences. This has already been foreseen by Comte and this is why he made metaphysics the heir of "theology." But he concluded from this that the idea of force is destined to disappear from science; for, owing to its mystic origins, he refused it all objective value. But we are going to show that, on the contrary, religious forces are real, howsoever imperfect the symbols may be, by the aid of which they are thought of. From this it will follow that the same is true of the concept of force in general.
