Where so much is discord it is well, if it be possible, to start with a basis of agreement. And on one point, at least, there is substantial unity among critics. There is a general agreement among students of folk lore, comparative mythology, and anthropology, that religious ideas rest ultimately upon an interpretation of nature that is now generally discarded. Differing as they do on details, there is consent upon this point. It is the world of the savage that originates the religion of the savage, and upon that rests the religions of civilized man as surely as his physical structure goes back to the animal world for its beginning. And in giving birth to a religious explanation of his world the savage was only pursuing the normal path of human development. Mankind progresses through trial and error; doubtful and erroneous theories are framed before more reliable ones are established, and while truth may crown our endeavours it seldom meets us at the outset. Religious beliefs thus form man's earliest interpretation of nature. On this there is, as I have said, general agreement, and it is as well not to permit ourselves to lose sight of that in the discussion of the various theories that are put forward as to the exact nature of the stages of religious development. In many directions the less accurate theories of things are replaced gradually and smoothly by more reliable explanations. But in religion this is not so. For many reasons, with which we are not now immediately concerned, religious beliefs are not outgrown without considerable "growing pains." And a long time after the point of view from which religious beliefs sprang has been given up, the conclusions that were based on that point of view are held to most tenaciously. And yet if one accepts the scientific story of the origins of religious ideas there seems no justification whatever for this. Religion cannot transcend its origin. Multiply nothing to infinity and the result is still nothing. Illusion can beget nothing but illusion, even though in its pursuit we may stumble on reality. And no amount of ingenuity can extract truth from falsehood.
