We can understand this mentality the better since it has not yet completely disappeared from our midst. If the principle of determinism is solidly established to-day in the physical and natural sciences, it is only a century ago that it was first introduced into the social sciences, and its authority there is still contested. There are only a small number of minds which are strongly penetrated with this idea that societies are subject to natural laws and form a kingdom of nature. It follows that veritable miracles are believed to be possible there. It is admitted, for example, that a legislator can create an institution out of nothing by a mere injunction of its will, or transform one social system into another, just as the believers in so many religions have held that the divine will created the world out of nothing, or can arbitrarily transmute one thing into another. As far as social facts are concerned, we still have the mentality of primitives. However, if so many of our contemporaries still retain this antiquated conception for sociological affairs, it is not because the life of societies appears obscure and mysterious to them; on the contrary, if they are so easily contented with these explanations, and if they are so obstinate in their illusions which experience constantly belies, it is because social events seem to them the clearest thing in the world; it is because they have not yet realized their real obscurity; it is because they have not yet recognized the necessity of resorting to the laborious methods of the natural sciences to gradually scatter the darkness. The same state of mind is found at the root of many religious beliefs which surprise us by their pseudo-simplicity. It is science and not religion which has taught men that things are complex and difficult to understand. But the human mind, says Jevons,[30] has no need of a properly scientific culture to notice that determined sequences, or a constant order of succession, exist between facts, or to observe, on the other hand, that this order is frequently upset. It sometimes happens that the sun is suddenly eclipsed, that rain fails at the time when it is expected, that the moon is slow to reappear after its periodical disappearance, etc. Since these events are outside the ordinary course of affairs, they are attributed to extraordinary exceptional causes, that is to say, in fine, to extra-natural causes. It is under this form that the idea of the supernatural is born at the very outset of history, and from this moment, according to this author, religious thought finds itself provided with its proper subject.
