I can scarcely now say whether in those moments I was more overcome with thankfulness that Nature was so like Revelation, or more filled with wonder that Revelation was so like Nature. Nature, it is true, is a part of Revelation—a much greater part doubtless than is yet believed—and one could have anticipated nothing but harmony here. But that a derived Theology, in spite of the venerable verbiage which has gathered round it, should be at bottom and in all cardinal respects so faithful a transcript of "the truth as it is in Nature" came as a surprise and to me at least as a rebuke. How, under the rigid necessity of incorporating in its system much that seemed nearly unintelligible, and much that was barely credible, Theology has succeeded so perfectly in adhering through good report and ill to what in the main are truly the lines of Nature, awakens a new admiration for those who constructed and kept this faith. But however nobly it has held its ground, Theology must feel to-day that the modern world calls for a further proof. Nor will the best Theology resent this demand; it also demands it. Theology is searching on every hand for another echo of the Voice of which Revelation also is the echo, that out of the mouths of two witnesses its truths should be established. That other echo can only come from Nature. Hitherto its voice has been muffled. But now that Science has made the world around articulate, it speaks to Religion with a twofold purpose. In the first place it offers to corroborate Theology, in the second to purify it.
If the removal of suspicion from Theology is of urgent moment, not less important is the removal of its adulterations. These suspicions, many of them at least, are new; in a sense they mark progress. But the adulterations are the artificial accumulations of centuries of uncontrolled speculation. They are the necessary result of the old method and the warrant for its revision—they mark the impossibility of progress without the guiding and restraining hand of Law. The felt exhaustion of the former method, the want of corroboration for the old evidence, the protest of reason against the monstrous overgrowths which conceal the real lines of truth, these summon us to the search for a surer and more scientific system. With truths of the theological order, with dogmas which often depend for their existence on a particular exegesis, with propositions which rest for their evidence upon a balance of probabilities, or upon the weight of authority; with doctrines which every age and nation may make or unmake, which each sect may tamper with, and which even the individual may modify for himself, a second court of appeal has become an imperative necessity.
Science, therefore, may yet have to be called upon to arbitrate at some points between conflicting creeds. And while there are some departments of Theology where its jurisdiction cannot be sought, there are others in which Nature may yet have to define the contents as well as the limits of belief.
What I would desire especially is a thoughtful consideration of the method. The applications ventured upon here may be successful or unsuccessful. But they would more than satisfy me if they suggested a method to others whose less clumsy hands might work it out more profitably. For I am convinced of the fertility of such a method at the present time. It is recognized by all that the younger and abler minds of this age find the most serious difficulty in accepting or retaining the ordinary forms or belief. Especially is this true of those whose culture is scientific. And the reason is palpable. No man can study modern Science without a change coming over his view of truth. What impresses him about Nature is its solidity. He is there standing upon actual things, among fixed laws. And the integrity of the scientific method so seizes him that all other forms of truth begins to appear comparatively unstable. He did not know before that any form of truth could so hold him; and the immediate effect is to lessen his interest in all that stands on other bases. This he feels in spite of himself; he struggles against it in vain; and he finds perhaps to his alarm that he is drifting fast into what looks at first like pure Positivism. This is an inevitable result of the scientific training. It is quite erroneous to suppose that science ever overthrows Faith, if by that is implied that any natural truth can oppose successfully any single spiritual truth. Science cannot overthrow Faith; but it shakes it. Its own doctrines, grounded in Nature, are so certain, that the truths of Religion, resting to most men on Authority, are felt to be strangely insecure. The difficulty, therefore, which men of Science feel about Religion is real and inevitable, and in so far as Doubt is a conscientious tribute to the inviolability of Nature it is entitled to respect.
None but those who have passed through it can appreciate the radical nature of the change wrought by Science in the whole mental attitude of its disciples. What they really cry out for in Religion is a new standpoint—a standpoint like their own. The one hope, therefore, for Science is more Science. Again, to quote Bacon—we shall hear enough from the moderns by-and-by—"This I dare affirm in knowledge of Nature, that a little natural philosophy, and the first entrance into it, doth dispose the opinion to atheism; but, on the other side, much natural philosophy, and wading deep into it, will bring about men's minds to religion."[2]
The application of similia similibus curantur was never more in point. If this is a disease, it is the disease of Nature, and the cure is more Nature. For what is this disquiet in the breasts of men but the loyal fear that Nature is being violated? Men must oppose with every energy they possess what seems to them to oppose the eternal course of things. And the first step in their deliverance must be not to "reconcile" Nature and Religion, but to exhibit Nature in Religion. Even to convince them that there is no controversy between Religion and Science is insufficient. A mere flag of truce, in the nature of the case, is here impossible; at least, it is only possible so long as neither party is sincere. No man who knows the splendor of scientific achievement or cares for it, no man who feels the solidity of its method or works with it, can remain neutral with regard to Religion. He must either extend his method into it, or, if that is impossible, oppose it to the knife. On the other hand, no one who knows the content of Christianity, or feels the universal need of a Religion, can stand idly by while the intellect of his age is slowly divorcing itself from it. What is required, therefore, to draw Science and Religion together again—for they began the centuries hand in hand—is the disclosure of the naturalness of the supernatural. Then, and not till then, will men see how true it is, that to be loyal to all of Nature, they must be loyal to the part defined as Spiritual. No science contributes to another without receiving a reciprocal benefit. And even as the contribution of Science to Religion is the vindication of the naturalness of the Supernatural, so the gift of Religion to Science is the demonstration of the supernaturalness of the Natural. Thus, as the Supernatural becomes slowly Natural, will also the Natural become slowly Supernatural, until in the impersonal authority of Law men everywhere recognize the Authority of God.
To those who already find themselves fully nourished on the older forms of truth, I do not commend these pages. They will find them superfluous. Nor is there any reason why they should mingle with light which is already clear the distorting rays of a foreign expression.
But to those who are feeling their way to a Christian life, haunted now by a sense of instability in the foundation of their faith, now brought to bay by specific doubt at one point raising, as all doubt does, the question for the whole, I would hold up a light which has often been kind to me. There is a sense of solidity about a Law of Nature which belongs to nothing else in the world. Here, at last, amid all that is shifting, is one thing sure; one thing outside ourselves, unbiased, unprejudiced, uninfluenced by like or dislike, by doubt or fear; one thing that holds on its way to me eternally, incorruptible, and undefiled. This more than anything else, makes one eager to see the Reign of Law traced in the Spiritual Sphere. And should this seem to some to offer only a surer, but not a higher Faith; should the better ordering
