are to yield nothing for the higher life. If the development of doctrine is to have any meaning for the future, Theology must draw upon the further revelation of the seen for the further revelation of the unseen. It need, and can, add nothing to fact; but as the vision of Newton rested on a clearer and richer world than that of Plato, so, though seeing the same things in the Spiritual World as our fathers, we may see them clearer and richer. With the work of the centuries upon it, the mental eye is a finer instrument, and demands a more ordered world. Had the revelation of Law been given sooner, it had been unintelligible. Revelation never volunteers anything that man could discover for himself—on the principle, probably, that it is only when he is capable of discovering it that he is capable of appreciating it. Besides, children do not need Laws, except Laws in the sense of commandments. They repose with simplicity on authority, and ask no questions. But there comes a time, as the world reaches its manhood, when they will ask questions, and stake, moreover, everything on the answers. That time is now. Hence we must exhibit our doctrines, not lying athwart the lines of the world's thinking, in a place reserved, and therefore shunned, for the Great Exception; but in their kinship to all truth and in their Law-relation to the whole of Nature. This is, indeed, simply following out the system of teaching begun by Christ Himself. And what is the search for spiritual truth in the Laws of Nature but an attempt to utter the parables which have been hid so long in the world around without a preacher, and to tell men at once more that the Kingdom of Heaven is like unto this and to that?
PART II.
The Law of Continuity having been referred to already as a prominent factor in this inquiry, it may not be out of place to sustain the plea for Natural Law in the Spiritual Sphere by a brief statement and application of this great principle. The Law of Continuity furnishes an a priori argument for the position we are attempting to establish of the most convincing kind—of such a kind, indeed, as to seem to our mind final. Briefly indicated, the ground taken up is this, that if Nature be a harmony, Man in all his relations—physical, mental, moral, and spiritual—falls to be included within its circle. It is altogether unlikely that man spiritual should be violently separated in all the conditions of growth, development, and life, from man physical. It is indeed difficult to conceive that one set of principles should guide the natural life, and these at a certain period—the very point where they are needed—suddenly give place to another set of principles altogether new and unrelated. Nature has never taught us to expect such a catastrophe. She has nowhere prepared us for it. And Man cannot in the nature of things, in the nature of thought, in the nature of language, be separated into two such incoherent halves.
The spiritual man, it is true, is to be studied in a different department of science from the natural man. But the harmony established by science is not a harmony within specific departments. It is the universe that is the harmony, the universe of which these are but parts. And the harmonies of the parts depend for all their weight and interest on the harmony of the whole. While, therefore, there are many harmonies, there is but one harmony. The breaking up of the phenomena of the universe into carefully guarded groups, and the allocation of certain prominent Laws to each, it must never be forgotten, and however much Nature lends herself to it, are artificial. We find an evolution in Botany, another in Geology, and another in Astronomy, and the effect is to lead one insensibly to look upon these as three distinct evolutions. But these sciences, of course, are mere departments created by ourselves to facilitate knowledge—reductions of Nature to the scale of our own intelligence. And we must beware of breaking up Nature except for this purpose. Science has so dissected everything, that it becomes a mental difficulty to put the puzzle together again; and we must keep ourselves in practice by constantly thinking of Nature as a whole, if science is not to be spoiled by its own refinements. Evolution being found in so many different sciences, the likelihood is that it is a universal principle. And there is no presumption whatever against this Law and many others being excluded from the domain of the spiritual life. On the other hand, there are very convincing reasons why the Natural Laws should be continuous through the Spiritual Sphere—not changed in any way to meet the new circumstances, but continuous as they stand.
But to the exposition. One of the most striking generalizations of recent science is that even Laws have their Law. Phenomena first, in the progress of knowledge, were grouped together, and Nature shortly presented the spectacle of a cosmos, the lines of beauty being the great Natural Laws. So long, however, as these Laws were merely great lines running through Nature, so long as they remained isolated from one another, the system of Nature was still incomplete. The principle which sought Law among phenomena had to go further and seek a Law among the Laws. Laws themselves accordingly came to be treated as they treated phenomena, and found themselves finally grouped in a still narrower circle. That inmost circle is governed by one great Law, the Law of Continuity. It is the Law for Laws.
It is perhaps significant that few exact definitions of Continuity are to be found. Even in Sir W. R. Grove's famous paper,[21] the fountain-head of the modern form of this far from modern truth, there is no attempt at definition. In point of fact, its sweep is so magnificent, it appeals so much more to the imagination than to the reason, that men have preferred to exhibit rather than to define it. Its true greatness consists in the final impression it leaves on the mind with regard to the uniformity of Nature. For it was reserved for the Law of Continuity to put the finishing touch to the harmony of the universe.
Probably the most satisfactory way to secure for one's self a just appreciation of the Principle of Continuity is to try to conceive the universe without it. The opposite of a continuous universe would be a discontinuous universe, an incoherent and irrelevant universe—as irrelevant in all its ways of doing things as an irrelevant person. In effect, to withdraw Continuity from the universe would be the same as to withdraw reason from an individual. The universe would run deranged; the world would be a mad world.
There used to be a children's book which bore the fascinating title of "The Chance World." It described a world in which everything happened by chance. The sun might rise or it might not; or it might appear at any hour, or the moon might come up instead. When children were born they might have one head or a dozen heads, and those heads might not be on their shoulders—there might be no shoulders—but arranged about the limbs. If one jumped up in the air it was impossible to predict whether he would ever come down again. That he came down yesterday was no guarantee that he would do it next time. For every day antecedent and consequent varied, and gravitation and everything else changed from hour to hour. To-day a child's body might be so light that it was impossible for it to descend from its chair to the floor; but to-morrow, in attempting the experiment again, the impetus might drive it through a three-story house and dash it to pieces somewhere near the center of the earth. In this chance world cause and effect were abolished. Law was annihilated. And the result to the inhabitants of such a world could only be that reason would be impossible. It would be a lunatic world with a population of lunatics.
Now this is no more than a real picture of what the world would be without Law, or the universe without Continuity. And hence we come in sight of the necessity of some principle of Law according to which Laws shall be, and be "continuous" throughout the system. Man as a rational and moral being demands a pledge that if he depends on Nature for any given result on the ground that Nature has previously led him to expect such a result, his intellect shall not be insulted, nor his confidence in her abused. If he is to trust Nature, in short, it must be guaranteed to him that in doing so he will "never be put to confusion." The authors of the Unseen Universe conclude their examination of this principle by saying that "assuming the existence of a supreme Governor of the universe, the Principle of Continuity may be said to be the definite expression in words of our trust that He will not put us to permanent intellectual confusion, and we can easily conceive similar expressions of trust with reference to the other faculties of man."[22] Or, as it has been well put elsewhere, Continuity is the expression of
