Scripture: see his 'De Auctoritate Scripturæ Sacræ.' A conviction of the importance of natural theology spread very rapidly in the seventeenth century. This contributed to awaken an interest in the various religions of the world, and thus led to the rise of what may be called Comparative Theology, although more generally designated the Philosophy of Religion. Its origin is to be sought in the attempts made to prove that the principles of natural theology were to be found in all religions. Lord Herbert of Cherbury's 'De Religione Gentilium,' published in 1663, was one of the earliest and most characteristic attempts of the kind. From that time to the present the study of religions has proceeded at varying rates of progress, but without interruption, and has at length begun to be prosecuted according to the rules of that comparative method which has, in the words of Mr Freeman, "carried light and order into whole branches of human knowledge which before were shrouded in darkness and confusion." The eighteenth century was the golden age of natural theology. The deists both of England and France endeavoured to exalt natural theology at the expense of positive theology by representing the former as the truth of which the latter was the perversion. "All religions in the world," said Diderot, "are merely sects of natural religion." The prevalent opinion of the freethinkers of his time could not have been more accurately expressed. It was just what his predecessors in England meant by describing Christianity as "a republication of natural religion," and by maintaining that it was "as old as the creation." The wisest opponents of the deists, and thoughtful Christian writers in general--the adherents of the moderate and rational theology of the seventeenth and eighteenth centuries--strove, on the other hand, to show that natural theology was in reality presupposed by revelation, and that it should carry the mind onwards to the acceptance of revelation. But there were some who undertook to maintain that there was no such thing as natural theology; that reason of itself can teach us absolutely nothing about God or our duties towards Him. The Hutchinsonians, for example, whose best representatives, besides the founder, were Bishop Horne of Norwich, and William Jones, curate of Nayland, believed that all knowledge of religion and morals, and even the chief truths of physical science, ought to be drawn from the Bible. Dr Ellis, in his treatise entitled 'The Knowledge of Divine Things from Revelation, not from Reason or Nature' (1743), laboured to prove that neither the being of a God nor any other principle of religion could be legitimately deduced from the study of the phenomena of the universe. He argued on the assumption that the senses are the only natural inlets to knowledge. The late Archbishop Magee adopted his views on this subject. One of the most widely known expositions and defences of the theory is that contained in the 'Theological
