It is eternally true that nature must triumph in the long run. Theories are very imposing, doubtless, but when they are erected on a misconception the inexorable fact is sure to assert itself sooner or later, and with pitiless serenity level the magnificent fabric with the dust. It is this which gives to scientific men so grave and calm an attitude; theologians wrangle fiercely and bitterly because they wrangle about _opinions_, and one man's say is as good as another's where both deal in intangibles; but the man of science, when absolutely sure of his ground, _can afford to wait_, because the fact he has discovered remains unshaken, however it be assailed, and it will, in time, assert itself. When nature and revelation then come into contact, revelation must go to the wall; no outcry can save it; it is doomed; as well try and dam the rising Thames with a feather, as seek to bolster up a theology whose main dogmas are being slowly undermined by natural science. Of course no one nowadays (at least among educated people, for Zadkiel's Almanac I believe still protests on Biblical grounds against the heresy of the motion of the earth) dreams of maintaining Bible, _i e_., revealed, science against natural science; it is agreed on all hands that on points where science speaks with certainty the words of the _Bible must be explained so as to accord with the dictum of nature_; _i e._, it is allowed--though the admission is wrapped up in thick folds of circumlocution--that science must mould revelation, and not revelation science. The desperate attempts to force the first chapter of Genesis into some faint resemblance to the ascertained results of geological investigations are a powerful testimony to the conscious weakness of revealed science and to the feeling on the part of all intelligent theologians that the testimony graven with an iron pen on the rocks cannot be contradicted or refuted. In fact so successfully has science asserted its own preeminence in its own domain that many defenders of the Bible assert loudly, to cover their strategic movement to the rear, that revelation was not intended to teach science, and that scientific mistakes were only to be expected in a book given to mankind by the great Origin of all scientific law. They are freely welcome to find out any reasons they like for the errors in revealed science; all that concerns us is that their revelation should get out of the way of advancing science, and should no longer interpose its puny anathemas to silence inquiry into facts, or to fetter free research and free discussion.
