In America, except Mr. Alger's admirable monograph on the "Doctrine of the Future Life," we have scarcely anything worthy of notice. Mrs. Lydia Maria Child's work on the "Progress of Religious Ideas" deserves the greatest credit, when we consider the time when it was written and the few sources of information then accessible.[2] Twenty-five years ago it was hardly possible to procure any adequate information concerning Brahmanism, Buddhism, or the religions of Confucius, Zoroaster, and Mohammed. Hardly any part of the Vedas had been translated into a European language. The works of Anquetil du Perron and Kleuker were still the highest authority upon the Zendavesta. About the Buddhists scarcely anything was known. But now, though many important _lacunæ_ remain to be filled, we have ample means of ascertaining the essential facts concerning most of these movements of the human soul. The time seems to have come to accomplish something which may have a lasting value. § 3. Ethnic Religions. Injustice often done to them by Christian Apologists. Comparative Theology, pursuing its impartial course as a positive science, will avoid the error into which most of the Christian apologists of the last century fell, in speaking of ethnic or heathen religions. In order to show the need of Christianity, they thought it necessary to disparage all other religions. Accordingly they have insisted that, while the Jewish and Christian religions were revealed, all other religions were invented; that, while these were from God, those were the work of man; that, while in the true religions there was nothing false, in the false religions there was nothing true. If any trace of truth was to be found in Polytheism, it was so mixed with error as to be practically only evil. As the doctrines of heathen religions were corrupt, so their worship was only a debasing superstition. Their influence was to make men worse, not better; their tendency was to produce sensuality, cruelty, and universal degradation. They did not proceed, in any sense, from God; they were not even the work of good men, but rather of deliberate imposition and priestcraft. A supernatural religion had become necessary in order to counteract the fatal consequences of these debased and debasing superstitions. This is the view of the great natural religions of the world which was taken by such writers as Leland, Whitby, and Warburton in the last century. Even liberal thinkers, like James Foster[3] and John Locke,[4] declare that, at the coming of Christ, mankind had fallen into utter darkness, and that vice and superstition filled the world. Infidel no less than Christian writers took the same disparaging view of natural religions. They considered them, in their source, the work of fraud; in their essence, corrupt superstitions; in their doctrines, wholly false; in their moral tendency, absolutely injurious; and in their result, degenerating more and more into greater evil.
