such tests are in reality nothing but hypotheses to which a greater or lesser degree of probability attaches. Suppose now—always bearing in mind the imperfect character of our powers of observation—we were to observe that certain plants or species of animals developed by training and circumstances into new species, or to see plants being transformed into animals, or even to notice literally “the foal of a wild ass born a man,” what would all this prove? That the Creator endowed the species of plants and animals with such properties as would enable them to transform into new species, or into any other of the species already in existence; but it does not follow that the Creator must have adopted the same method in the act of creation. He created as many species as His wisdom determined, although they might all have been able to develop from one single species. Suppose the problem which the Alchymists of the Middle Ages proposed to themselves, viz., to produce an animal being by mere chemical combination, had actually been solved, would any one have believed that all animals had been produced in that way? Or does the success of artificial hatching of eggs convince any person that all birds have sprung from artificially hatched eggs? The same argument applies to the geological formation of the earth. We notice changes brought about through natural forces, and mark the amount of change effected in a certain period; we are then able to calculate what time would be required for such or such a change—provided that only those laws be in force which we have noticed in our calculation. Is it reasonable or logical to apply to the act of creation the laws which have been brought into force through this very act? “He said, and it was: He commanded, and they were created” (Ps. xxxiii. 9). The word of God produced in a moment what the natural forces established by the Creator would effect by gradual development in millions of years. It is true that the earth is one of the most insignificant bodies in the universe, and man is a small portion of the creatures on earth, and yet it is neither impossible nor unreasonable to believe that the benefits which man derives from the various parts of the creation, from the sun, the moon, and the stars, were essential elements in the scheme of the All-wise Creator.
