And so in every department of science the Bible is always true to nature, and has invariably been in advance of all human investigations and discoveries. How many thousands of years have metaphysicians and psychologists been at work to map out, classify, and gauge the various capacities and powers of the human mind and soul! But they have found no way of approach to the heart so masterly and effective as that taken by the Scriptures; and the more that is known of the nature of the man, the more clearly is it seen that the Bible comprehended it from the commencement. It has been but a few years since Newton laid open the laws of gravitation; and yet the Scriptures spoke of the earth being hung "upon nothing," as if familiar with the whole subject, before human science had begun to form even its feeblest guesses in the case. It has only been since the invention of the telescope enabled men to search through the starry spaces that Sir John Herschel has discovered in the northern sky a peculiar barrenness; but more than three thousand years ago Job told Bildad the Shuhite that "God stretched out the north over the empty place." It has been but a few years since science discovered "that the sun is not the dead center of motion, around which comets sweep and planets whirl," but that "the earth and sun, with their splendid retinue of comets, satellites, and planets, are all in motion around some point or center of attraction inconceivably remote, and that that point is in the direction of the star Alcyone, one of the Pleiades"; which would hence seem to be "the midnight throne" in which the whole system of gravitation has its central seat and from which all material orbs are governed. But the Bible asked the question, more than thirty centuries ago, "Canst thou bind the sweet influences of Pleiades?" as if the speaker knew all about the facts in the case. How long has it been since the doctrine of the rotundity of the earth has been settled by scientific men? yet the Psalmist spoke of "the round world"; and Solomon described in brief the true theory of wind-currents, and strongly hinted the circulation of the blood, at least twenty-five hundred years ago. And, with all the advances of knowledge which have so wonderfully marked the last three hundred years, in which the spirit of philosophic inquiry has ranged the universe, searched heaven, earth, and sea, knocked at every door, peered into every recess, consulted every oracle of nature, and gathered trophies of power and treasures of wisdom and sublimities of knowledge at which the world has been amazed,--in all the motions which the experimentist has traced, in all the principles of power which the master of physics has discovered, in all the combinations which the chemist has detected, in all the forms which the naturalist has recorded, in all the spiritual phenomena which the metaphysician has described, and in all the conditions and relations of mind or
