To carry it as a working principle into so lofty a region may appear impracticable. Difficulties lie on the threshold which may seem, at first sight, insurmountable. But obstacles to a true method only test its validity. And he who honestly faces the task may find relief in feeling that whatever else of crudeness and imperfection mar it, the attempt is at least in harmony with the thought and movement of his time.

That these papers were not designed to appear in a collective form, or indeed to court the more public light at all, needs no disclosure. They are published out of regard to the wish of known and unknown friends by whom, when in a fugitive form, they were received with so curious an interest as to make one feel already that there are minds which such forms of truth may touch. In making the present selection, partly from manuscript, and partly from articles already published, I have been guided less by the wish to constitute the papers a connected series than to exhibit the application of the principle in various directions. They will be found, therefore, of unequal interest and value, according to the standpoint from which they are regarded. Thus some are designed with a directly practical and popular bearing, others being more expository, and slightly apologetic in tone. The risk of combining two objects so very different is somewhat serious. But, for the reason named, having taken this responsibility, the only compensation I can offer is to indicate which of the papers incline to the one side or to the other. "Degeneration," "Growth," "Mortification," "Conformity to Type," "Semi-Parasitism," and "Parasitism" belong to the more practical order; and while one or two are intermediate, "Biogenesis," "Death," and "Eternal Life" may be offered to those who find the atmosphere of the former uncongenial. It will not disguise itself, however, that, owing to the circumstances in which they were prepared, all the papers are more or less practical in their aim; so that to the merely philosophical reader there is little to be offered except—and that only with the greatest diffidence—the Introductory chapter.

In the Introduction, which the general reader may do well to ignore, I have briefly stated the case for Natural Law in the Spiritual World. The extension of Analogy to Laws, or rather the extension of the Laws themselves so far as known to me, is new; and I cannot hope to have escaped the mistakes and misadventures of a first exploration in an unsurveyed land. So general has been the survey that I have not even paused to define specially to what departments of the Spiritual World exclusively the principle is to be applied. The danger of making a new principle apply too widely inculcates here the utmost caution. One thing is certain, and I state it pointedly, the application of Natural Law to the Spiritual World has decided and necessary limits. And if elsewhere with undue enthusiasm I seem to magnify the principle at stake, the exaggeration—like the extreme amplification of the moon's disc when near the horizon—must be charged to that almost necessary aberration of light which distorts every new idea while it is yet slowly climbing to its zenith.

In what follows the Introduction, except in the setting there is nothing new. I trust there is nothing new. When I began to follow out these lines, I had no idea where they would lead me. I was prepared, nevertheless, at least for the time, to be loyal to the method throughout, and share with nature whatever consequences might ensue. But in almost every case, after stating what appeared to be the truth in words gathered directly from the lips of Nature, I was sooner or later startled by a certain similarity in the general idea to something I had heard before, and this often developed in a moment, and when I was least expecting it, into recognition of some familiar article of faith. I was not watching for this result. I did not begin by tabulating the doctrines, as I did the Laws of Nature, and then proceed with the attempt to pair them. The majority of them seemed at first too far removed from the natural world even to suggest this. Still less did I begin with doctrines and work downward to find their relations in the natural sphere. It was the opposite process entirely. I ran up the Natural Law as far as it would go, and the appropriate doctrine seldom even loomed in sight till I had reached the top. Then it burst into view in a single moment.

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
