And in addition to these points there should be brought out distinctly a _corollary_, which is, that science must be studied by its own means and to its own ends, unmixed with the means and unbiased by the motives of investigators in other fields, and uncontrolled by consciences unenlightened by itself. The very finger of the Almighty seems to have written the proofs of this truth on human history. No one can gainsay it. It is decisive, for it is this: _There has never been a scientific theory framed from the use of Scriptural texts, wholly or partially, which has been made to stand_. Such attempts have only subjected their authors to derision, and Christianity to suspicion. From Cosmas finding his plan of the universe in the Jewish tabernacle, to Increase Mather sending mastodon's bones to England as the remains of giants mentioned in Scripture; from Bellarmin declaring that the sun cannot be the centre of the universe, because such an idea "vitiates the whole Scriptural plan of salvation," to a recent writer declaring that an evolution theory cannot be true, because St. Paul says that "all flesh is not the same flesh," the result has always been the same.[158] Such facts show that scientific hypothesis will be established or refuted by scientific men and scientific methods alone, and that no conscientious citation of texts, or outcries as to consequences of scientific truths, from any other quarter, can do any thing save retard truth and cause needless anxiety.[159] Such facts show, too, that the sacred books of the world were not given for any such purpose as that to which so many men have endeavored to wrest them--the purpose served by compends of history and text-books of science. Is skepticism feared? All history shows that the only skepticism which does permanent harm is skepticism as to the value and safety of truth as truth. No skepticism has proved so corrosive to religion, none so cancerous in the human brain and heart. Is faith cherished? All history shows that the first article of a saving faith, for any land or time, is faith that there is a Power in this universe strong enough to make truth-seeking safe, and good enough to make truth-telling useful.
