To this philosophy may be applied the word of the Apostle: “Beware lest any man cheat you by philosophy and vain deceit” (Col. ii. 8). No, it is not the spirit of true science that opposes the belief in supernatural factors, but it is the desertion of the traditions and the spirit of a better science. To the representatives of paganism, to _Plato_ and others, the highest goal of human quest of truth was to find God and to worship Him. For the great leaders in recent natural science, _Copernicus_, _Kepler_, _Newton_, _Linné_, _Boyle_,_ Volta_, _Faraday_, and _Maxwell_, the highest achievement was to point to God’s wisdom in the wonderful works of nature; their science ended in prayer. A principle of unbroken natural causation, as a boycott of the Deity, was to them not a postulate of science but an abomination. They were carried by a conviction expressed by a later scientist, _W. Thomson_, in the following words: “Fear not to be independent thinkers! If you think vigorously enough, you will be forced by science to believe in a God, Who is the basis of all religion”; and expressed by _R. Mayer_ in the following words: “True philosophy must not and cannot be anything else but the propædeutics of the Christian religion.” But let us proceed. We have before us an astonishing _order_, we behold uncounted wonders of well-designed purpose in the world. The question suggests itself: Whence this Order? The watch originates from the intelligence of a maker, an accident could not have produced it; hence also the great world-machine must have had an intelligent maker. This is the logic of unbiassed reason. But the principles of liberal research object to the acceptance of this explanation. What is theirs?
