The vital theory regards nature as the product and the continued work of an ever-living and ever-creating Spirit, who is the immediate fountain of all force, and the immanent life of all that lives. It looks upon the universe "as the manifestation and the abode of a Free Mind like our own," who realizes his thoughts in its collocations and adjustments, embodies his ideals in its typical forms, and by his free volition subordinates nature to the higher purposes of intellectual and moral life--the formation of noble human characters. In a world so constituted prayer is a real power, and human character is a free development through the power of prayer which influences that ever-present Will that sustains our life. The mechanical theory regards the world as a huge machine supplied with motor power in the primal act of creation, and then left to make its own history according to rigid laws of mechanics and "the multiplication table." There is no "Power which makes for righteousness," and no purpose of love mingling in the necessary order of things. Evolution is the only law of creation; there is nothing spontaneous, nothing free. All the processes of nature, all the forms of life, all the facts of consciousness, all the sympathies, sacrifices, joys, and sorrows of social life, and all the noble or ignoble deeds of history, are only mechanical functions which can be weighed or measured, and catalogued in tables of statistics. Inflexible necessity, inexorable law, absolute uniformity, unbroken continuity tell the story of the universe. In such a world there is no place for prayer, or at most it is but the cry of anguish wrung from the lips of those who are being mangled and crushed by the ponderous mechanism, which floats away into the infinite spaces, and never finds a living ear or touches a compassionate heart. Then, as Dr. Hedge puts the melancholy case, "We must rough it as best we can with driving-wheel and fly-wheel, and trust that the power may not fail and the gearing foul in our short day." This is the position of some, but by no means of the majority of the scientists of our time. We venture the assertion that it is no part of the doctrine of modern science, neither does it follow as a logical consequence from any of the accepted principles of modern science, nor does it reflect the real feeling of the best exponents of modern science.
