the two Kingdoms than the analogy of their Phenomena—a unity which the poet's vision, more quick than the theologian's, has already dimly seen:—

The function of Parable in religion is to exhibit "form by form." Law undertakes the profounder task of comparing "line by line." Thus Natural Phenomena serve mainly an illustrative function in Religion. Natural Law, on the other hand, could it be traced in the Spiritual World, would have an important scientific value—it would offer Religion a new credential. The effect of the introduction of Law among the scattered Phenomena of Nature has simply been to make Science, to transform knowledge into eternal truth. The same crystallizing touch is needed in Religion. Can it be said that the Phenomena of the Spiritual World are other than scattered? Can we shut our eyes to the fact that the religious opinions of mankind are in a state of flux? And when we regard the uncertainty of current beliefs, the war of creeds, the havoc of inevitable as well as of idle doubt, the reluctant abandonment of early faith by those who would cherish it longer if they could, is it not plain that the one thing thinking men are waiting for is the introduction of Law among the Phenomena of the Spiritual World? When that comes we shall offer to such men a truly scientific theology. And the Reign of Law will transform the whole Spiritual World as it has already transformed the Natural World.

I confess that even when in the first dim vision, the organizing hand of Law moved among the unordered truths of my Spiritual World, poor and scantily-furnished as it was, there seemed to come over it the beauty of a transfiguration. The change was as great as from the old chaotic world of Pythagoras to the symmetrical and harmonious universe of Newton. My Spiritual World before was a chaos of facts; my Theology, a Pythagorean system trying to make the best of Phenomena apart from the idea of Law. I make no charge against Theology in general. I speak of my own. And I say that I saw it to be in many essential respects centuries behind every department of Science I knew. It was the one region still unpossessed by Law. I saw then why men of Science distrust Theology; why those who have learned to look upon Law as Authority grow cold to it—it was the Great Exception.

I have alluded to the genesis of the idea in my own mind partly for another reason—to show its naturalness. Certainly I never premeditated anything to myself so objectionable and so unwarrantable in itself, as either to read Theology into Science or Science into Theology. Nothing could be more artificial than to attempt this on the speculative side; and it has been a substantial relief to me throughout that the idea rose up thus in the course of practical work and shaped itself day by day unconsciously. It might be charged, nevertheless, that I was all the time, whether consciously or unconsciously, simply reading my Theology into my Science. And as this would hopelessly vitiate the conclusions arrived at, I must acquit myself at least of the intention. Of nothing have I been more fearful throughout than of making Nature parallel with my own or with any creed. The only legitimate questions one dare put to Nature are those which concern universal human good and the Divine interpretation of things. These I conceive may be there actually studied at first-hand, and before their purity is soiled by human touch. We have Truth in Nature as it came from God. And it has to be read with the same unbiased mind, the same open eye, the same faith, and the same reverence as all other Revelation. All that is found there, whatever its place in Theology, whatever its orthodoxy or heterodoxy, whatever its narrowness or its breadth, we are bound to accept as Doctrine from which on the lines of Science there is no escape.

When this presented itself to me as a method, I felt it to be due to it—were it only to secure, so far as that was possible, that no former bias should interfere with the integrity of the results—to begin again at the beginning and reconstruct my Spiritual World step by step. The result of that inquiry, so far as its expression in systematic form is concerned, I have not given in this book. To reconstruct a Spiritual Religion, or a department of Spiritual Religion—for this is all the method can pretend to—on the lines of Nature would be an attempt from which one better equipped in both directions might well be pardoned if he shrank. My object at present is the humbler one of venturing a simple contribution to practical Religion along the lines indicated. What Bacon predicates of the Natural World, Natura enim non nisi parendo vincitur, is also true, as Christ had already told us, of the Spiritual World. And I present a few samples of the religious teaching referred to formerly as having been prepared under the influence of scientific ideas in the hope that they may be useful first of all in this direction.

I would, however, carefully point out that though their unsystematic arrangement here may create the impression that these papers are merely isolated readings in Religion pointed by casual scientific truths, they are organically connected by a single principle. Nothing could be more false both to Science and to Religion than attempts to adjust the two spheres by making out ingenious points of contact in detail. The solution of this great question of conciliation, if one may still refer to a problem so gratuitous, must be general rather than particular. The basis in a common principle—the Continuity of Law—can alone save specific applications from ranking as mere coincidences, or exempt them from the reproach of being a hybrid between two things which must be related by the deepest affinities or remain forever separate.

To the objection that even a basis in Law is no warrant for so great a trespass as the intrusion into another field of thought of the principles of Natural Science, I would reply that in this I find I am following a lead which in other departments has not only been allowed but has achieved results as rich as they were unexpected. What is the Physical Politic of Mr. Walter Bagehot but the extension of Natural Law to the Political World? What is the Biological Sociology of Mr. Herbert Spencer but the application of Natural Law to the Social World? Will it be charged that the splendid achievements of such thinkers are hybrids between things which Nature has meant to remain apart? Nature usually solves such problems for herself. Inappropriate hybridism is checked by the Law of Sterility. Judged by this great Law these modern developments of our knowledge stand uncondemned. Within their own sphere the results of Mr. Herbert Spencer are far from sterile—the application of Biology to Political Economy is already revolutionizing the Science. If the introduction of Natural Law into the Social sphere is no violent contradiction but a genuine and permanent contribution, shall its further extension to the Spiritual sphere be
