In reality, it is not even approached. It is inadmissible that systems of ideas like religions, which have held so considerable a place in history, and to which, in all times, men have come to receive the energy which they must have to live, should be made up of a tissue of illusions. To-day we are beginning to realize that law, morals and even scientific thought itself were born of religion, were for a long time confounded with it, and have remained penetrated with its spirit. How could a vain fantasy have been able to fashion the human consciousness so strongly and so durably? Surely it ought to be a principle of the science of religions that religion expresses nothing which does not exist in nature; for there are sciences only of natural phenomena. The only question is to learn from what part of nature these realities come and what has been able to make men represent them under this singular form which is peculiar to religious thought. But if this question is to be raised, it is necessary to commence by admitting that they are real things which are thus represented. When the philosophers of the eighteenth century made religion a vast error imagined by the priests, they could at least explain its persistence by the interest which the sacerdotal class had in deceiving the people. But if the people themselves have been the artisans of these systems of erroneous ideas at the same time that they were its dupes, how has this extraordinary dupery been able to perpetuate itself all through the course of history? One might even demand if under these conditions the words of science of religions can be employed without impropriety. A science is a discipline which, in whatever manner it is conceived, is always applied to some real data. Physics and chemistry are sciences because physico-chemical phenomena are real, and of a reality which does not depend upon the truths which these sciences show. There is a psychological science because there are really consciousnesses which do not hold their right of existence from the psychologist. But on the contrary, religion could not survive the animistic theory and the day when its truth was recognized by men, for they could not fail to renounce the errors whose nature and origin would thus be revealed to them. What sort of a science is it whose principal discovery is that the subject of which it treats does not exist? CHAPTER III LEADING CONCEPTIONS OF THE ELEMENTARY RELIGION--_continued_ II.--_Naturism_
