At what a tremendous cost, it may be observed by the way, is such a result achieved. The philosophy of universal necessity places man in the same predicament as it does simple matter. If all nature excludes voluntary control, and is subject only to an iron rule of invariable succession, then man also must himself be incapable of voluntary control, whether it comes from a supreme will or from his own. Thus the warfare which assails miracles, threatens to destroy all ideas of freedom and moral responsibility. And this dark foreshadowing is not concealed. "Step by step," we are confidently and calmly told, "the notion of evolution by law is transforming the whole field of our knowledge and opinion. Not the physical world alone is now the domain of inductive (?) science, but the moral, the intellectual, and the spiritual are being added to the empire. It is the crown of philosophy to see the immutable even in the complex action of human life."[37] But when all assumptions are denied, the whole question presents another aspect. Given the fundamental distinction between things physical and things moral; given the higher nature of man, the personal existence of God, a moral element in the Divine rule, the immortality of the human soul, and the present vicinity of invisible spiritual realms; and, immediately, miracles wrought by the Divine will for men's moral welfare are completely removed out of the sphere of the impossible. Positivism, Atheism, and Pantheism are considered in other lectures of this course, and therefore it is not my office to examine them. To what has been said by the Archbishop of York and the Rev. Mr. Jackson, and to what may be said by the Rev. Dr. Rigg, I must refer my hearers. I would only observe in passing, what, indeed, I have hinted at already, that it puzzles me beyond description to conceive how, by any course of natural evolution, independent of the introduction of a new force by an overruling power, the phenomena of the human will with its morally creative energy for good and evil could have been produced. To solve, on the principle of pure development, the problem of the genesis of that mysterious faculty, is an insuperable task. If we may speak of what is inconceivable--and scientific men set us the example--we should say the existence of volition in man, with its moral accompaniments, is utterly inconceivable, apart from belief in a Divine will, of which ours is the offspring.
