CHAPTER XIII
RELIGIOUS IDEAS
Religion and religious ideas are among the most remarkable products of the human spirit. With all their reason-defying assertions and astounding incongruities, they seem at first sight inexplicable. Time out of mind, therefore, men have found it difficult to conceive them as having arisen otherwise than through a supernatural or divine revelation, which, it would follow, must originally have been imparted to all men alike. But gradually, as people became acquainted with the more or less rudimentary religions of the various races, which often differ greatly on the most essential matters, they began to doubt the accuracy of this assumption, and came more and more to consider whether religious ideas must not be reckoned as a natural product of the human mind itself, under the influence of its surroundings.
The first theory was that they arose from a religious craving common to all human beings, which was itself, therefore, in a certain sense supernatural.
