The discussions conducted in the following pages are designed to be of interest and profit to all thoughtful readers, and not simply to those who are engaged in theological studies or more general scientific investigations. The treatise is a popular putting of scientific results rather than processes and methods. As nearly as possible The treatlse it is a comprehensive view of the universe in its p°i>ular- known facts and laws as it protends in time and space. "Who ever, whether learned or unlearned, is interested in the pursuit of such knowledge will find here a profitable and fascinating study. As he turns page after page, and the marvels of the uni verse and the story of its unfolding passes before him, he cannot fail to be entranced and lifted. He will find himself encom passed with realities which, filling him with wonder, will also transfigure him and clothe all being, himself with the rest, with a new significance. The style is, of purpose, popular. No reader will find himself troubled to understand any sen tence, even where the subject is obscure. All great facts are great thoughts of God. The facts here given are the greatest known to man — the most Great faets ° D great thoughts certain and, in some respects, highest revelation of God. God has made of himself. Eevelation supplements creation with more definite information with respect to his moral administration over men and other intelligences, but in the vis ible realm he is seen most manifestly in the greatness and glory of his perfections. Vlll Pbeface. This treatise is designed to serve as a text to the discussion to follow on " The Nature and Attributes of the Supreme Being," furnishing as it does the grounds for rational induc tion of these profoundly mysterious themes. It must not be classed among the treatises which attempt a reconciliation between the ascertained facts of science and re ligion or the teachings, doctrinal or historical, of " holy writ." The facts and the writ, properly interpreted and understood, are in perfect accord. The seeming of contradiction arises from ignorant or perverse interpretation. The object here proposed is to set forth the ascertained facts Ascertained without reference to their bearings on any doctrinal facts. teachings of any book or school of thought. Facts must dominate any system, come from what source it may. This is an inevitable law. The first and last demand of mind is truth, which is but another name for facts, and involved principles, which must always and necessarily be harmonious. There is no contradiction between truths, and no demand for reconcilement. They must be accepted, no difference what goes down. "When ascertained one set of facts or one truth may shed a light which will put to flight preconceived notions, but will not, cannot, discredit other truths, but, on the contrary, must aid to a better interpretation and understanding of them, so far as they are affected at all. "We solicit ministers especially to the reading of these pages. special bene- The benefits to be derived are various.

The knowledge of the great facts of being which scientific research is developing is indispensable to one who would hold the attention of the age and command its respect. The theology that will live and which can never die is that which will harmonize with the facts of the universe. Tneology tnat They must be sought and known, and the theological w111 live- professor and preacher must show himself acquainted with the facts and be competent to show that his teachings do not require that they should be ignored. He must recognize them and deal with them. He may not be required to preach science from the pulpit or to become a lecturer in science, but he must know the facts, and not preach or teach doctrines which collide with them. More than that, in the tumult of thought which every new discovery creates, and amid the roar and clamor which is ever and anon raised against popular theological be liefs and teachings, he must be able to satisfy himself first, and then the people to whom he speaks with pen or tongue, that, while some long-regnant ideas may require to be abandoned as rubbish of ignorance, the citadel remains intact. The strength of any system is the truth which it holds ; its weakness is the errors which infest it. If it is all strengai of a error it is utterly worthless and harmful. If it has system' some errors of incidents and minor points they may be relin quished without harm, and its power thereby be increased. If its errors are shown to be not inherent, but the accidents of misinterpretation merely, it is made stronger by the exposure x Preface. if its expounders and defenders show themselves pleased with the discovery and glad to amend the mistake. Nothing can save a system which shrinks from investigation, or attempts to build itself on ignorance, or the impudent denial of facts, or refusal to know them, or inability to show that it does not contradict them. In the interest of theology we plead for the freest and largest liberty. "We hail every new discovery. Every new truth, no difference what old error or system of error it may shake down and utterly destroy, is a harbinger of the millennium. The word Creation, which stands as principal in the title of this volume, is used in its proper sense as a noun, and is the equivalent of all things that exist — the universe. It assumes that all of whatever exists is product of creative energy except the energy, or source of the energy, which creates, and which is necessarily eternal. The further words of the title, to wit, God in Time and Space, are designed to imply that all created existence is prod uct of divine energy exerted in a progressive method and continuous forthputting of power to fill out the measure of infinite thought. The object of the discussion is to show the vastness of crea tion in its space and time measures, and its method of advance from the incipient material atom to the topmost result of spiritual existence, from chaos to cosmos, from the inorganic to the organic, and from the organic to the superorganic, and from the superorganic, or merely sentient, to the higher super- organic or spiritual realm. The inorganic and organic, both insensate and sensate, are assumed to be primary stages, or platforms, which have their meaning in a service they render to the final outcome of a spiritual and immortal universe. Preface. xi The author aims to show that there is a difference between the inorganic and merely organic realms which requires spe cific energizings of the divine Author equivalent to diverse creative acts, and that the same is true between the insensate, or vegetable creation, and the sensate, or animal creation ; and that the same is true, also, between the sentient, or merely animal, and the rational and higher spiritual forms of life. Man is shown to be the final product, and the most recent in the time order of existence, and the final cause, or end of the entire creative movement, whose advent explains and puts meaning in all the antecedent stages of the creative drama. It is shown, not merely, that man is the most recent member of the series, but more than that, that his advent is very recent, at furthest not more than eight or ten thousand years ago, while all other known living beings date back perhaps hundreds of thousands of years. The several theories of a more ancient humanity, possibly of inferior qualities and type, and of plurality of origin, are ex amined and shown to be without evidence to support them. All the evidence points to one head of all the ethnic varieties, and that head the Adam of revelation. Finally, it is assumed as probable, but as unproven by any facts within our knowledge, that the universe is peopled by numerous intelligences of various grades of power and glory, some of whom are superior to man, perhaps, in age and per fection, others possibly as recent. When we say unproved, we mean that there are no facts within our absolute knowledge to establish the certainty that there are personal beings other than those of our own race and the infinite Author himself, but there are known facts which render the conclusion highly probable, and therefore worthy of faith ; indeed, such as render it quite irrational to doubt. xii Preface. One book whose authority we are compelled (we mean, of course, by stress of evidence) to accept as divine testimony is conclusive. The Bible speaks with no uncertain voice on the subject. We accept without hesitation its testimony. "While the popular but declining doctrine of so-called evolu tion — the doctrine that one thing is by inhering forces the source and cause of another and succeeding member of the series, and so that all things are traceable to a primitive atom — is discounted as unscientific and impossible, it is shown that there is a true relation between all forms of existence, each antecedent serving as ground and condition of each succeed- ent — a close consecutive chain running through and binding all together into a complete and united whole. It is shown that this beautiful harmony is brought about, not by the un intelligent working of so-called natural forces, but by a con tinuous divine energizing in created substances of which each specific force is simply a mode or result, the entire series being thus an absolute effect of the forthputting of divine thought by exercise of divine power. As the universe itself in all its parts and as a completed whole is a product of divine thought and power, we recognize that all the forces which play in it as causative of the result are simply direct modes of divine energizing, or indirect but pur posed and inevitable results of established relations among the things created. Things created do nothing independently of their author. Man is the only being known to us who by his Creator is endowed with power whereby he becomes the author of his own acts. The author will have accomplished his highest aim if in the mind of the reader he shall have awakened deeper reverence Preface. xiii for the great Author of the marvelous universe system by placing before him a more adequate view of the mighty work as it extends backward through immeasurable ages, and outward over limited but semi-infinite spaces ; and especially if he shall have been able to furnish him a proximately true clew to the method of the great movement from the beginning to the present ; and more especially still if he shall have aided him to a discovery of the great end had in view — an end of ineffable love. We stand in the middle of the process, and with our finite powers we but dimly perceive its meanings, but we see that it has profound meanings, and from the imperfect comprehension we have we are able to discern something of the outcome. Ages yet may be required to unravel all its mysteries, but we cannot doubt that far on its revelations will not only make plain what is now obscure, but will also bring to us new and higher mani festations of the infinite love and wisdom which inspired and directed it from the beginning to the end — nay, to the forever progressing wonder that will have no end.

THE UNIVERSE. PRELIMINARY OBSERVATIONS. Earnest minds cannot think of God without a sense of awe ; and revelation in so many ways teaches of his greatness that a mind filled with its exalted imagery and august doctrines, even though its conceptions may be vague, must be impressed with a profound sense of his majesty and glory ; but reflection and enlarged knowledge of his works cannot fail to give added dignity and substance to his conceptions. The universe of reality will transcend that of imagination — the invisible things of him, even his eternal power and Godhead, here come to light and certainty. Wisdom, power, and majesty gleam from every atom and from every organism. There is nothing any more little or unmeaning, or that does not point to the one all-glorious Founder of the mighty system ; nothing that does not tell of his love and create confidence in his goodness and beget faith in the beneficent outcome of his plan, however for the present it may be enveloped in mystery and insoluble perplexities to our finite and limited faculties. For ages — indeed, until recently — but relatively little was accurately known of the universe in any respect, untn recently " the universe but especially as to its constitution, laws, forces, uttie known. order of development, and actual history. At last scientific re search has replaced the crude conceptions of ignorance and blind imagination with something approximating truth and reality, and bids fair to still further unveil the long-hidden mystery of its beautiful order and harmonies. 4 Studies in Theology. The true conception of the universe has such manifold rela tions to the true knowledge of its Author that in approaching the study of his nature, attributes, and character it will be of profit to us to refresh our minds with a brief survey of it. It must, of course, be brief and suggestive in a treatise like this, and general and popular rather than strictly scientific ; but it should be sufficiently comprehensive to bring the universe pres ent to our thought somewhat as it is in reality. The survey in itself will be profitable without reference to anything ulterior ; it is tonicful and broadening to the faculties to grapple with vast things. The universe is, next to the In finite as he reveals himself in his word, the best door of ap proach to him. To what is to follow it is, if not absolutely indispensable, exceedingly important, and will not fail to be helpful to the reader, to consult the book styled Cosmic Theism, in this series. At the point where we enter existence we find ourselves point where environed by a vast semi-infinite complex of beins we enter the r & universe. and change. The objects we behold on every hand differ among themselves in almost infinite variety of form, texture, habit, use, and power. They seem to have relations to each other and a kind of unity. They come and go with variable regularity. Some kinds and groups seem to depend on other kinds and groups. A change here emerges in a change yonder. Gradually it dawns upon us that we are in the midst of a deftly arranged system. The multitude comes to unity, and changes march to the rhythm of a plan. We ultimately discern that, so far from an anarchic mass merely, there is not an atom that is not held to a line by inexorable law. We emerge out of what seemed at first a chaos into a deft and beautiful cosmos. A multiplicity of forces play in and around us, but they are all guided by intelligence, and without excep- Preliminary Observations. 5 tion work to ends of harmony and beneficence. The reign of law is discovered to be universal. The discovery of orderly action in the wondrous system im mediately gives rise to two questions, namely, Is the observed order from within the system itself, or is it and the system itself superimposed from without? and are we able from the ob served operation of forces, or master force exerted and trace able in past and present effects, to discern the trend and probable outcome? The first of these questions is fully discussed in Cosmic The ism* of this series. The second is in part considered in the same treatise, but will be more fully developed in the present dis cussion. The discussion on which this volume enters is logically pre liminary to the discussion of the nature, attributes, and charac ter of God.f Recognizing the fact and fundamental principle that the Bible is an authoritative and infallible teacher on these great points, and as such must be court of last resort and final appeal, it is assumed here that for its correct interpretation and understanding the universe must be interrogated and its facts elicited, as illustrative aud exponential. Here God is seen in action. Action is the deepest revelation of an agent. Better than words, as giving meaning to words, it discloses what Actlou better in truth the agent is. When the acts are obscure, or tnan words- but imperfectly apprehended, word statements serve as guides and helps, and when supported by adequate evidence determine the significance of acts themselves, placing them in a clearer light, and leading the weak and vacillating understanding to a dis covery of deeper meaning than it, unaided, could reach. Thus revelation usefully supplements manifestations and helps to * See Cosmic Theism, by the author. f See Nature and Attributes of God, by the author. 6 Studies in Theology. right understanding. The two never do nor can disagree. Each when properly used is helpful to the other. The knowl edge of each, possibly not in the same degree, is essential to the interpretation of the other, or if not absolutely essential is in disputably helpful. In any event, nothing is more certain than that facts of the f ts must universe must have an important bearing on the na- ruie. ture an(j character of its author. For this reason, be fore entering upon the higher theme which lies more remote from us and in the deepest obscurity, we propose in the present volume to deal with the plainer facts which lie immediately about us. The facts of the universe are multitudinous. Some lie upon raets muititu- *ke surface and are easily discovered ; others are dmous. concealed in the deepest obscurity and are difficult of discovery, not alone as to their causes and significance, but as to the facts themselves. No telescope has yet measured the vast areas of the system ; no microscope has penetrated to its minutest constituents. There are still unexplored realms, in all directions and departments. The survey we propose is of some of the more conspicu ous and significant of the known facts, ascertained, not by casual observation merely, but by the accredited methods and most rigorous tests of science. System, orderly processes, intelligible sequences, are the manifestations of mind. A thought factor is intuitively dis cerned in every arranged series. Any force expressed in the series, or necessary to it, points to a personal agent as exerting it— is directly or indirectly personal force. The canon is, wherever plan or system is discerned as means canon tost. to ends> and ths means are effective to the ends, intel ligence is invariaUy and necessarily precedent, and is efficacious cause of the plan, the force employed, and the out- Preliminary Observations. 7 come, so that did no such intelligence exist, neither plan, nor force, nor outcome could exist. There must be, as antecedent, the personal planner in order to the plan. The planner must exert the force or employ it mas terfully in order to the end. The outcome shows first of all the planner ; then the intelligent purpose ; then the force exerted to effect it. This relation is absolute and necessary. This is but another form of the maxim, "There can be no effect, which means change of any kind, without a cause." This is a universal canon. The effect in the case supposed is not merely an effect of force resulting in a change of some kind, but of a force ex erted or controlled by intelligence in order to a preconceived end, and therefore a force which requires a personal agent. If we could suppose the intelligence in the agent withdrawn the effect could not take place ; the force, in fact, could not exist. Every natural force which we call a law is itself invisible, the idea of it in the mind arising, by way of neces- Natural sary inference, out of an observed order of facts. And forces- very often, if not always, in our conception of these forces we are investing them with the attributes of intelligence and of will, at the very moment, perhaps, when we are stumbling over the difficulty of seeing in them the experiments of a mind which is intelligent and of a will which is supreme. The deeper we go in science, the more certain it becomes that all the realities of nature are in the region of the invisible, so that the saying is literally and not merely figuratively true that the things which are seen are temporal, and it is only the things which are not seen that are eternal. For instance, we never see the phenomenon of life disassociated from organization. Yet the prof oundest physiologists have come to the conclusion that organization is not the cause of life, but, on the contrary, that life is the cause of organization; life being something— a force of some kind, by whatever name we may call it — which 8 Studies in Theology. precedes organization, and fashions and builds it up. This was the conclusion come to by the great anatomist Hunter, and it is the conclusion indorsed in our own day by such men as Dr. Carpenter and Professor Huxley, men whose philosophy cer tainly has no bias toward either theological or metaphysical -explanations, or toward belief in anything which cannot be seen and weighed and handled. But what is vital force. It is something which wo cannot -see, but of whose existence we are as certain as we are of its visible effects — nay, which our reason tells us precedes and is superior to these. We often speak of material forces, as if we could identify any kind of force with matter. But this is only one of the many ambiguities of language. All that we mean by a material force is a force which acts upon matter, and pro duces in matter its own appropriate effects. We must go a step further, therefore, and ask ourselves, What is force ? What is our conception of it ? What view can we form, for example, of the real nature of that force, the measure of whose operation has been so exactly ascertained, the force of gravitation ? It is invisible, imponderable. All our words for it are but circum locutions to express its phenomena or effects. There are many kinds of force in nature — which we distin guish after the same fashion — according to their effects or according to the forms of matter in which they become cogni zable to us. But if we trace all our conceptions on the nature of force to their fountain head, we shall find that they are formed on our own consciousness of living effect— of that force which has its seat in our own vitality, and especially with that kind of it which can be called forth at the bidding of the will. If we can ever know anything of the nature of any force, it ought to be of this one. And yet the fact is that we know nothing. If then we know nothing of that kind of force which is so near us, and with which our own intelligence is in such close Preliminary Observations. 9 alliance, much less can we know the ultimate nature of force in its other forms. It is important to dwell on this, because both the aversion with which some men regard the idea of the reign of law, and the triumph with which some others hail it, are founded on a notion that when we have traced any given phenomena to what are called natural forces we have traced them further than we really have. We know nothing of the ultimate nature or of the ultimate seat of force. Science, in the modern doctrine of the conservation of energy and the convertibility of forces, is already getting something like a firm hold of the idea that all kinds of force are but 0utunes 0l forms or manifestations of some one central force astronomy. issuing from some one fountain head of power. Sir John Herschel has not hesitated to say that " it is but reasonable to regard the force of gravitation as the direct or indirect result of a Consciousness or a Will existing somewhere." And even if we cannot certainly identify force in all its forms with the direct energies of an omnipotent and all-pervading will, it is at least in the highest degree unphilosophical to assume the con trary — to speak or to think as if the forces of nature were either independent of, or ever separate from, the Creator's power. It follows, then, from these considerations, that whatever difficulty there may be in conceiving of a will not exerted by a visible person is a difficulty which cannot be evaded by arrest ing our conceptions at the point at which they have arrived in forming the idea of laws or forces. That idea is itself made up out of elements derived from our own consciousness of per sonality. This fact is seen by men who do not see the inter pretation of it. They denounce as a superstition the idea of any personal will separable from the forces which work in nature. They say that this idea is a mere projection of our own per sonality into the world beyond— the shadow of our own form cast upon the ground on which we look. And, indeed, this in 10 Studies in Theology. a sense is true. It is perfectly true that the mind does recog nize in nature a reflection of itself. But if this be a deception, it is a deception which is not derived by transferring the idea of personality to the abstract idea of force, or by investing combinations of force with the attributes of mind. * The most stringent advocates of naturalism cannot free them selves of personal cause without assumptions and presumptions Personal so violent as to shock their own intelligence. The cause nee- , t essary. necessity which compels us to impute mind where we behold an orderly arrangement is in the nature of mind — it is universal, it is irresistible. If the order is discovered in the arrangement of the parts of unliving matter we spontaneously say, Who did it ? or, What is it for ? or, How ingenious it is ! If it is a thing of life we instinctively attribute intelligence to the source of life, in whatever form the life appears. This sponta neous conclusion is supported when we submit the subject to reflection. It is impossible for us to reason ourselves into the chance im- belief that the orderly arrangements of nature are the possible. igsues of ghan^ Nor do we find content wnen we attempt to conceive that somehow nature built itself by blind forces. We cannot rest until we impute personality to the cause. It is forced upon us that there was and is a mind back Mind back °f all. It holds us with 'the unrelaxing grip of a nec essary truth, that the force which projects order is an ordering and arranging agent or personal being. When we conscious- translate nature from within we find three facts al- ness in re lation to ways in our consciousness. They are these : first, we consciously feel that we have power and exert it volitionally ; second, when we consciously exert force which issues in orderly arrangement we know that a mental process precedes volitional activity ; third, we know that when arrange- * Reign of Law, pp. 119-121. Preliminary Observations. 11 ment emerges in an orderly way the order was enforced from without, under conditions of thought and will. We infer, and the inference is a necessity of thought, that the same must be true in every like case of orderly arrangement. If now we locate the arranging forces in matter we do not get rid of this law. We must still posit a thinking and volitionating agent in order to the result. And- if we find, as we do, nature constituting one ineffable, all-inclusive system, we are compelled to posit one all- embracing force, exerted by one thought and will factor. That force, be it what it may and wheresoever located, requires infi nite intelligence and omnipotence as its source. If we locate it in matter we simply impute personality to matter and clothe it with infinite attributes, thus transforming it into God. But this idea is beset with so many violent presumptions against it that reason at once and unalterably rejects it. We are driven by stress of necessity to seek the home of the agent manifest ing itself in some extra immaterial being. There is no re spectable thinker who any more doubts the presence and opera tion of personal agency in the universe. Spirit is recognized as a substance different from matter, and possessed of the very attributes of thought and intelligence manifested in matter. It is of the essence of effects that they should have a begin ning : and, therefore, that there should be a time when Effects must o ' > ' have begin- all effects were nonexistent. It is of the essence of ning. cause that it should be existent in order to the effect of which it is cause. Ultimate cause must therefore be antecedent to all beginnings, and must therefore be itself unbegun, self-existent and eternal. No effect can have anything which was not imparted by its cause ; therefore the aggregate of effects can pos sess nothing which was not imparted by the ultimate ^"J1"*6 cause. The forces which are operative in the universe nai. are therefore derived from, or manifestation of, the one original 12 Studies in Theology. force factor — are but forms of his direct agency, and can in no case transcend what he puts in them. All of which again is but the maxim, " Every effect must have a cause." It thus ap pears not only that the determinative factor in the universe is mind, but that all forces emanate from the ultimate intelli gent cause. For our purpose it is not necessary to enter fur ther into the argument. Method of the Eternal Cause. 13 TO FIND THE METHOD OF THE ETERNAL CAUSE. Starting with this postulate, our aim is to find whether we can so put ourselves into relations with the eternal Cause as to discover his plan and method, and the ultimate end and out come of his personal activity. There are two ways by which mind communicates with mind, whereby one mind detects the existence of other mind, Two ways ii r • ii i -»«-. of dlscover- and becomes aware ot its methods and aims. Mmd ing mmd. itself is invisible. We can neither see it nor see its act. This is true both of internal and external seeing. The mind does not per ceive other mind or other mind acting, except as results occur. The results are what are seen, and the cause is seen in them and not apart from them. If we were dependent on direct perception it would elude us entirely. Mind manifests itself in words and acts, and in no case discovers itself directly. We can only know that it is, and what are its thoughts, feelings, purposes, and plans, by some word revelation of itself, or by some external act which it causes. Even the consciousness of itself emerges only when it is active. The Infinite must possess methods of communication peculiar to himself. Finite mind reads mind only through sym- Difference bols. It has no power to intuit other minds — to gaze ^Zite&na on them in their pure subjectivity— to read their quies- tne flnite- cent states; indeed, it can only know itself in action. The Infinite may — naV) must — have a power to read the inward states of mind without the outward symbol, and may have the power to commu nicate with and awaken and guide the thought powers of finite minds without the aid of external phenomenal manifestations. 14 Studies in Theology. The two methods, or ways, rather, in which finite mind is Language a a^e *° detect the existence of and become commu- means. nicant with other minds are : First, by means of words, spoken or written. Spoken words are sounds addressed to the ear. Written words are characters or forms addressed to the eye. To these, as of the same kind, may be added mo tion signs, addressed to the eye or touch. In order to the use of this method the communicant minds must be so posited as to employ these symbols ; that is, must be invested with some kind of sensorium. There must also be a community in the signs employed. Each mind must attach the same meaning to, or must invest the same mentality in, the symbol, before one can translate the other. These signs, in fact, are mutual for mal thoughts, so that in employing them each discloses to the other that he has the same thought. The language symbol may be an impartation to both, or a creation by both. The power of language — varied mental vocalization, as Language evinced by man— is a special endowment conferred bothagiltand _ _ -1 an invention, in creation, differing in scope and quality from the inarticulate sounds of inferior living creatures — an instrument intended for the use of mind and bestowed with .the gift of intelligence. It is a spontaneity of mind, but there can be little doubt that in quantum sufficit for immediate use it was conferred at the beginning. But language is also a growth, keep ing pace with mental development — an instrument first existing in posse in the human mind and organs, and emerging into reality as needs demand. It is an elaboration of human skill, ever increasing, ever growing in compass, definiteness, and perfection, but as yet inadequate to the perfect expression of all mental states, needs, and wants. So far forth as the vocal or written symbol is definite and comprehensive and significant of the same thing to the various minds employing it, it serves Method of the Eternal Cause. 15 as means of communication between them. That it may be the servitor of truth it must have breadth, delicacy, flexibility, fixedness, and the communicant minds must be able to know that the meanings they attach are language as a identical. An unknown word conveys no idea, or c^mmTnica-0' misleads and confuses. Developed language is the in- tlon" dispensable medium of accurate thought with reference to things which lie outside of immediate perception, and, indeed, must with relation to all matters of thought be forever the chief means of mind communicating with mind. Bereft of the serv ice of a common language, it would be impossible for minds to compare their perceptions, and more impossible still to com municate to each other their reflective processes and rational con clusions. Language is not only the creation of mind for the purpose of expressing itself, but it is the conservator of thought, the medium of treasuring it up in imperishable forms. With out it there could be no growth of knowledge, or relatively but little. The whole inner world of consciousness would for ever remain expressionless. So the Infinite, when he created minds, endowed them with the versatile power of language, both that he might communicate with them and that they might be possessed of a common medium of intercommunication among themselves, and that they might hold in permanence and make common all acquired knowledge. But for this endow ment it is difficult to conceive how the intelligence of man could greatly have transcended that of the brute creation. Even brute life is endowed with a measure of mentality and corresponding linguistic capacity, by which adequate power of correspondence between individuals may be maintained and the ends of existence be secured. With man the endowment is large, in proportion to the demands of the higher range of his faculties and requirements of his more profound and varied wants and experiences. Thus mind is able to communicate 10 Studies in Theology. with mind not simply with respect to the objectives of sense — external material forms and their qualities — but also with respect to whatever is held in consciousness — thoughts, feeling, motives, purposes, principles of action, emotions, volitions, and whatever else characterizes mental and ethical states and activities.

When we see the external act, which is all that we can see, we intuit the in ternal act in its two elements of thought and will, and at the same time cognize the invisible agent. Acts and results of acts are a kind of language the meanings of which we acquire with great facility. As in the case of verbal symbols the me dium may not be perfect ; no one mind may be able adequately to translate another mind, but the laws of mind are so unique that average mentality will be able to detect the significance of a well-developed series of observed acts. The interpretation will require faculty, and will depend on Require fac- sufficient time, breadth, and continuity of observed and'opportul facts, with close and thoughtful attention. If the ntt?- acts are obscure or the connections uncertain, in volved, conclusions will be correspondingly unreliable ; but if the acts be clear and articulate and the opportunity full for a complete examination, and, especially, if they are such that the observing mind can view them in all possible aspects, the in terpretation will be proximately certain. The same intelligent agent may employ both methods or but one, and either one of the two,; may put himself in rela- Method of the Eternal Cause. 17 tions with other minds and unfold himself to them by acting under their observation or by communicating in The samt words, or both.

Should he adopt both, truth would re- eacb- quire that there should be perfect harmony between them, and content to the observing mind would require that the harmony should be apparent, or at least that there should be no appear ances of irreconcilable contradiction. When practicable the greatest accuracy and the most perfect content would be attained by the combination of both methods. The word explanation might suggest some things which the most careful and able observer would not detect from the act alone ; might relieve points of obscurity by giving the clew ; might save expenditure of time and force by immediate revelation, and in many other ways might be beneficial. We have the clear conviction that the great Mind discovera ble in the universe has added a word explanation to God haa em a work manifestation, and we cannot doubt that it Ployed botn- has in many ways brought us to a clearer and more perfect under standing of his thought and purpose in the things that are seen., The scientific spirit which has. come to such prominence to day owes its existence to the progress which revelation inangu^ rated and brought forward ; and the discoveries it has made, and will make with accelerated rapidity,, are the indirect prod^ act of the right direction and great quickening revelation has given to human faculties and inquiries.

But, on the other hand, tha 3 « 18 Studies in Theology. most devout and reverent Christians must admit that there is an open door for scientific inquiry, and must rejoice in any aid to a better understanding of nature which it may furnish, and thus lead to a better understanding of the work.

The object is not to establish a harmony between the teachings of nature, scientifically and philosophically inter preted, and revelation, but to present a rational view of the di vine movement from the inception to the outcome of his work by a study of the works themselves. Occasional biblical facts will emerge, and it is believed the result of the inquiry will show that a rational theory will be in substantial accord with the word God has given, properly interpreted.

The only difference in that case between the authority of the word and the work would arise from the different degrees of certainty that we are not imposed on by appearances on the one side or the other. But the probability of deception in the case of a miracle or prophecy might be always greater than in that of a fact of nature ; and in case of an apparent conflict reason would so decide. But it should be remembered, in trying the case, that mere difference is not contradiction or conflict. A word communication may add something not contained in a work manifestation, and the absence of it in the former case would not disprove the truth of the word. There may be thoughts and purposes in the infinite which are not expressed Relative in mere nature, and which could never be deduced spheres. from any known facts or principles. A revelation containing an account of such could not be discredited by the mere pau city of nature. It might even reasonably be presumed that in matters of morals, where great interests are involved, and where reason, by reason of its slowness of action and the pau city of data, might prove an insufficient guide direct infor mation would be imparted. It could only be demanded, in such a case, that suitable evidence should be furnished. These are principles which every candid truth seeker should keep in mind ; and, properly observed, they will save ^J^to us from discarding the aids of a word communica- mind. tion too hastily, and from accepting it too indifferently or im- 20 Studies in Theology. perfectly ; and also from relying too exclusively on the teach ings of nature in all matters. They may properly leave science supreme in relation to some things, making it useful in correct- science su- jng anv vagaries and dreams which we have has- some cases, tily attributed to revelation, and the word be left supreme in another realm which mere science cannot reach. No fact of nature can furnish prima facie evidence against the pos sible and actual fact of a revelation, and no assumed revelation can discredit any fact of nature or limit the right of inquiry. The most casual observer will directly perceive three lines of Three lines of movement going on or being carried forward in the divine move ment, universe. The three lines of movement are : (a) the processes going forward in inorganic matter — azoic, particles and masses; (b) processes of life in all varieties ; (c) processes in the realm of mind or spirit. Throughout the movements are incessant and correlated, but always differentiable in law and method. We shall observe to little effect if we do not soon perceive a common ^na* ™ eacu department there is at least one com- characteristtc. mon characteristic, that of a progressive and well articulated unfolding from seemingly insignificant beginnings to grand and imposing outcomes. Nothing begins at per fection : first rudiments or germs, then advance by process to culminations ; each culmination serving but as fulcrum for some grander advance; the entire evolution revealing the matchless skill and inexhaustible resources of the mighty worker, and the inconceivable and endless richness of his design. In the first realm, the inorganic, the agent moves along the The inorganic line of nis advance by simple efflux of volitional realm. force, guidedby unerring skill, but even here never to the end per solium, but in the use of well-adjusted means Method of the Eternal Cause. 21 raised into second causes. But whether the end be reached by immediate creation or by mechanical approaches and long- drawn processes and indirections, in either case and alike his per sonal agency is sole cause, and may be traced by the studious ob server along the entire line, however it extends in time and space. In the second realm, the department of life, it is the same agent, but working in a different way. The results The organlc and laws of the older processes are taken up and sub- realm- ordinated to higher ends. Germ centers are created, and con stituted fulcra of a unique and previously unknown form of force which, under guidance of infinite skill, evolves an endless variety of living organisms, which sustain various relations to each other and to all inorganic existence in a multiform and beneficent economy called life. Here again he is sole agent, and the entire manifestation is manifestation of his power, wisdom, and beneficence. As in the former case, the movement is continuous and progressive, passing in vast measures of time from the lowest to the highest forms, each taking up the in ferior result already reached and advancing to a nobler type. In the third and crowning realm progress is again the law, but it is now a progress of the free individual along The realm of an endless line of possible improvement and per- mlnd- fection. The grade of being is different in essence and attri bute. It is invested with new qualities and dignities, and the law of its development is different and exceptional. The creative purpose is indicated in its constitution and asserted in its consciousness, but its attainment of its end is not enforced, as in every other case, from without, but is commit- Afreeforce ted to its own personality, and depends upon a free power al intra. Here we encounter for the first time the presence of a force that is independent and free in its action. 22 Studies in Theology. We rise into the region of proper agency : though created, a realm which is not under the divine force, but which is free under the restraints of law — a moral realm. To be able to deduce the purpose, method, and outcome of Agency ai- this triune movement of a strictly invisible agent, ^nsequent6 with the obscurities which necessarily surround it, difficulty. mustj confessedly, be extremely difficult. The data must be gathered from a wide field, both of time and space, and used with caution and care. Were we doomed to attempt the work single-handed, nothing could be more hopeless. The speck of time and limited space given to any individual observer, with the small power possessed by any one human mind, would render the task not simply hopeless, but absolutely impossible, and brand the attempt as the grossest folly and presumption. A clew to a mental movement, from observation, requires Demands of a that a sufficient part of the evolution should be clew- observed, not in isolated fragments, but in connec tion and relation. Then it is not impossible or even difficult. Once in the line we detect the meaning of each consecutive act, and forecast with ease the next step, and see on to the end. There is so much homogeneity in rational action that our mind reads not only what has been written, but on beyond, the lines that remain to be filled out. In the city where we dwell, some morning, we hear the au iiiustra- lieav7 tread of passing feet. Looking up we find it tioa- is a gang of workingmen going on to their toil. Our curiosity is excited, and we follow them to learn what it means. On closer observation we find that some are supplied with spades, others with picks, crowbars, drills, and powder cans. From the merest glance at the equipments we at once know this means excavation of some kind for some purpose ; we cannot tell yet what. Now they come to a halt, adjust themselves, and one begins to strike into the earth with a pick, another to Method of the Eternal Cause. 23 remove the loosened parts, another drills a hole in the rock ; already it is apparent what the implements are for. The work progresses ; a great hole is made in the earth, and the rocks and soil removed to convenient points of deposit. The sides of the excavation are trimmed to a line, and the angles are fixed. The blasted rock and other stone have been corded around the edges. Now new workmen appear with trowels, hammers, plummets, and other tools used in masonry. We now know that all this means a structure of some kind. Different kinds of dressed and undressed material are gathered. The foundations are laid, and the walls begin to go up — cross walls and openings. Long before the completion we are able to determine what the finished structure is to be and to what end it is built. The series of observed facts show the plan and pro claim the design. Simply looking at these we find what was in the mind of the worker at the start, and in what manner he chose to accomplish his purpose. We need no word statement in the presence of such facts, and any word statement could only conform to the facts. The act series is simply a thought series which emerges anew in the mind of the beholder. It is obvious that in order to translate the act series back to the thought series there must be homogeneity be- Tnetrend_ tween the worker and the observer. There must now obtained. also be enough facts of the series drawn out and observed in their exact order to constitute a trend. These conditions being fulfilled, the induction is likely to be proximately correct, and will not fail to be correct in its general character. The act series will emerge in a thought series as surely as it emerged from a thought series. It matters nothing that the act series is from the infinite, and that the observer and interpreter is finite. The finite may not comprehend either the plan or the method of the infinite as the infinite himself comprehends it ; but an act series of the 24 Studies in Theology. infinite may translate the thought series which it represents to The same the finite in a degree. The finite will see and think rgentbeflnue the thoughts of the infinite so far forth, though he or infinite. ma^ not comprehend the whole. Though we do not rise to the height of the design or fully comprehend any part of it, and though the working of the power be complete May not com- and absolute mystery to us, we may be able to get the prehend in fuii. trend of the vast movement to its utmost outcome. "Parts of his ways" we shall see though the greatness will transcend us ; " the remainder will be past finding out." It is a great undertaking "by searching" to find out God. It is hopeless to attempt to know him to perfection ; but is it im pious to hope that by diligent study we may at least learn something of his ineffable character and inscrutable plan ? The disadvantages are confessedly great. The worker, as to Disadvan- essence of being, is absolutely unapproachable by us tages. jn anv way. He hides himself behind an impene trable veil. He is incomprehensible in character, and modes both of being and action. In some way and for some rea son, out over immeasurable areas of time and space he sends vastness of signs of his existence. The field is so vast, and life the new. js s0 s]10rt and our standpoint so narrow, that we can only see a small part of these signals, and over all a vast obscurity hangs. From these insignificant atomic facts we are to undertake to interpret him. Necessarily much will be mean ingless to faculties which cannot grasp the whole, and where ob scurity is so profound some obscure facts will even be misleading. Can we find a clew ? Can we by any possibility get the line ? There are these encouraging circumstances with relation to the matter in hand which we do well to note : If the case is Encouraging beset with obscurity the obscurity is not so dense circum- . u stances. as it once was. We stand far along the line of the movement. The plan is far advanced in its development, and Method of the Eternal Cause. 25 a clew has been discovered. Multitudes of skillful workers have preceded us and furnish ready to our use a great accumu lation of materials. Their combined researches extend over centuries of time and cover a large part of the field of observa tion. We but construct out of the materials they have gath ered and sorted to our hands. In fact, they have laid the foundations and we but continue the walls which they have reared so well. The amount of patient work already done — quarrying in the earth, quarrying in the stars, ' quarrying in the mines of thought, blasting a way through the dense darkness of ignorance and the thick walls of prejudice and superstition ; work through midnight vigils ; work with fee ble bodies and overtaxed brains ; work many times with no rec ompense but derision ; work for the love of truth ; work that now enriches the world and will continue more and more to fer tilize coming ages — passes all estimation. It is thus by com bined toil of noble minds the structure of knowledge is built. Mere casual sense observation gives the fact of a great mass of inorganic existence, which in itself, merely Materlaiex. as observed, suggests nothing of a temporal order; istence mere- nothing of an historic process ; nothing of changes, served gives methodical or unmethodical, that have passed within temporal or- or before it ; nothing, in fact, but present existence and speculations. If we would know more we must linger and take note. That there is a temporal order we learn by research and ex perience. Bv closer and continued observation we Temporal r J order — how find an ongoing in ourselves and in things — markde ascertained. by sunrisings and sunsettings — by the succession of the sea sons ; by growth and decay ; by birth and death ; by that change which passes on things. The world, to casual observation, seems to be permanent and abiding. That it also had a birth 26 Studies in Theology. and history, and that there was any possibility of ascertaining the date of the one and tracing the events of the other, was not even surmised by the coming and vanishing generations of men that dwelt upon its surface. Whether it was young or old none could tell. Tradition made it young. But it has now become well known that there were processes going on from the beginning within the earth itself which Earth rec- were recording its marvelous history and laying it oras- away in the rocks forever. We have at last become aware of the processes, and have learned to translate the record with more or less accuracy. We know that any series must have a beginning and a history connecting the whole. Having found the clew, we are able to trace the successive changes to the primal movement ; and to pass beyond that to the eternal agent which gave it its start, and by successive effects to de- determine what kind of a being the agent was and is. From the study of these well-preserved records three things Three things force themselves upon us as absolute certainties: discovered, r^ tjiat tlie system ]ia^ a beginning ; (I) the lapse of almost immeasurable time since its origination; (c) the con stantly advancing dignity and worthiness of its ends and uses. The first of these assumed certainties encounters objection on so- called scientific grounds ; the second was long resisted by popular prejudice ; the third is in one form or another admitted by all. That the system had an absolute beginning is denied on two The system grounds : (a) as not ascertained in fact, and (b) as im- hadabegin- , ; \ / nmg. possible in conception ; the first is argued by science, which deals with facts ; the second by speculative philosophy, which deals with principles. The scientific objection rests upon these grounds in general : that origins do not come into the view of mind at all, and there fore cannot be made subject of scientific inquiry at all ; science Method of the Eternal Cause. 27 deals with facts, and does not find origins among facts. It allows of changes in things, and attempts to account for them Sclentifl0 by the things themselves ; but it denies that there is option. scientific evidence that the things themselves or the substances out of which they are composed have any beginning — that there is any proof of the great fundamental change from non existence to existence. It takes the universe as it now is, and analyzes, classifies, and explores its component parts, and deter mines the laws and forces by which its varied changes of form, relation, and condition are effected. It deals also with the changes which have taken place in its history, and those changes which can and will take place under its known laws in given relations and conditions. In this way it goes back over the past, as it finds it chronicled in the system itself in visible facts. It passes down through a long series of past changes, which it proposes to account for by ascertained laws and forces, until it comes to the ultimate components, when all changes cease, and here it comes to a halt and says it can go no further, there is no other more ultimate fact on which it can fix. It will not raise the question, Whence come these ultimates ? It has sim ply to do with the fact that they are, and with this to explain how all, changes have been wrought. If, stopping here, they assume that they have exhausted all reality they must with these alone carry forward all Failure to ac- the processes which they find going forward and all count- the results of change with which they deal. This is the problem. Can they do it ? They must find in these ultimates which go into the composition of all things and changes — ultimates of matter, law, and force as constituents of matter — " the promise and potency of all things," as has been asserted by a prominent devotee ; the ultimates must be able to do all that has been done, or they cannot account for it. If they, the ultimates, are impotent to the result, and if science has nothing more that it 28 Studies in Theology. can do, then the mind, by a necessity of its nature, must posit something, that is, some fact of being which science does not and cannot reach back of its ultimates. And that something must be the adequate explanation of origins, the source of the facts with which science deals, the absolute Creator. Three Three things considerations are fatal to the claim set up by the uraiism. " devotees of the " dirt theory." First, by definition of its advocates it is impersonal and nnf ree ; its forces necessa rily act ; it fails, therefore, to be able to give account of itself prior to the evolution of itself ; if by its nature it must act how could it be eternal ? Every act must be in time. Second, by confession it is not intelligent ; it fails, therefore, to account for the apparently intelligent manner of its operations. Third, by confession it is without life ; it fails, therefore, to account for life. Its impotency is so great that any attempt to explain the facts of the universe from it alone is conceded to be a fail ure by the most eminent minds who deal with the problem. The necessity of an agency outside of the material system The supernal- to acc0unt for it, that is, of a supernatural cause, is ural a neces- ' r ' sity. such that reason gives way and becomes unreason in attempting to resist it. The impotence of science makes no more against the doctrine of a supernatural cause than the im potence of mathematics in matters of morals makes against ethics. It simply lies outside of scientific inquiry, which deals with the facts of nature and not at all with its cause. When, on the ground that it has nothing to do with cause, it denies its ex istence, science transcends its sphere and drivels into idiocy. But at this point the question of origins encounters another tocTcSve'of obJectio11 from a different quarter, namely, the " im- origins. possibility of conceiving how being can be orio-i- nated." This must be admitted without hesitation and without reservation. The how of a properly creative act is an absolute Method of the Eternal Cause. 29 mystery to human intelligence. But does it therefore follow that it is impossible ? This would involve that our understand ing of how a thing can be is the measure of possibility. This will not be pretended. But is it then said that, at least, we cannot rationally believe that a thing is possible and actual the how of which we cannot conceive ? The answer is that this would limit our believing to our understanding, not of the fact which is matter of belief, but of how it became a fact. But this, again, cannot be assumed, and by a law of our mentality is impossible. We both necessarily believe and know the pos sibility and certainty of multitudes of things the how of which we do not comprehend — our own existence, for example. In this case we know that there must, in fact, be a properly crea tive act, since we know that we now are and that we once were not, and that to pass from nonexistence into existence requires a properly creative, causational exercise of power. The second assumed certainty, namely, that there has been a lapse of almost immeasurable time since the origi- The lapse of nation of the universe, is confessedly a recent dis- almos"nflnite •> time since the covery, but a fact now well established. The popular beginning. belief which long held undisputed sway, and which lingers in some quarters, was that creation was a very recent event, to be measured by at most only a few thousand years. There were no known facts to contradict it. It was supposed to have the highest sanction, the revealed testimony of the Creator himself. Authentic history seemed to favor it, in that it carried back but a brief period and seemed to reach to the infancy of things. There were abundant traditions circulating among all people to the same effect. The idea seemed to be an heirloom of hu manity, and carried unquestioning conviction wherever it cir culated. Not only history and tradition bore testimony to the recent origin of man, but numerous facts established it beyond 30 Studies in Theology. dispute. That the world itself was much older than its inhab itants was not suspected. Some strange facts were discovered in the constitution and position of the rocks. Inquiry was started. The facts mul- how discov- tiplied and became more and more curious and in- ered- teresting. More careful attention was given, and suspicion was engendered and expressed as to the truth of the popular theory of the recent origin of the world. It is within the memory of the gray-haired man, and need not be recited, how great the commotion that ensued. The result is that pa tient research has now established the fact beyond intelligent dispute that the beginning of the world must be dated back many, many millions of years. The same science has discovered also that the popular theory creation not 0f creation is not sustained by the facts, that is, as instantaneous ' . as a whole. long held and taught. That theory was that crea tion was begun and concluded in six solar days of twenty- four hours each. This also was supposed to be biblical and intrenched itself in the sanctuary of faith. It is certainly false. Better learning has discovered that such was not and never is the divine method. His plan extends through eter nity : why should he be in haste ? The examination shows that his movement was in the order of a continuous and systematic evolution or process extending over incompu table eons. The most primitive page records simply a vast accumulation primitive of elements — impalpable atomic substances — an abyss page. 0f vapor, of uncompounded gases, each discrete atom of which was under law. This was the product of the only properly creative act until we reach life and spirit, formative processes being not properly creative but constructive.

These were the infinitesimal stones Method of the Eternal Cause. 31 out of which in unrolling eons the creative agent was to con struct sidereal arches and evolve living races.

Thus we read the record from the Laurentian rocks of the first formed sedimentations to the Pliocene of the most recent, from the Eozoon of the metamorphic deposits to the human age. We know the laws and forces which have accumulated these vast masses and piled them tier upon tier and stratum upon stra tum to ten miles in thickness ; they are now working under our gaze. We see the process still going on, doing for our time what it did for those times, registering the chronology and his tory of to-day with the same stylus and on the same kind of page as was employed for those ages. The process is per fectly plain. We know how the accumulations were made and by what agencies. We know the forces which posited the walls and the ratios of their working, and the forces which dis turb and destroy. We see the result over all the surfaces of the world — not perfectly, but proximately. We know that Time for to make these vast deposits required inconceivable changes. measures of time. We know that the mass of the earth during that period has passed through great thermal changes— from a highly heated, perhaps molten, condition to Things its present temperature. We know that there was an almost infinitely long azoic period. We know that life has flourished through (probably) millions of years. We know that there have been epochs of life— that typical forms, characteristic of one period, have perished, to be followed by another order of typical forms. We know that there has been advance in the successive forms, each epoch introducing more complex and perfect organization. We know that each ante cedent condition furnishes something, not only in juxtaposition and temporal relation to what is immediately to follow, but something also essential to and prophetic of what is forthcom- no breas in ing- There is a deft correlation as well as consecu tion. There is no break in the chain from the first to the last link; but there are various elements in its composition Method of the Eternal Cause. 33 and progressive values in its parts. The first part is of iron, the second silver, the third gold, as to relative degree. The most ancient link in the still growing chain is, first, cre ated, impalpable elements, in their discrete and uncompounded forms — primitive atoms ; the second is the same ele ments molecularized, separated into masses, and development0 raised into palpable compounds; the third is masses and construt grouped into systems of cooled and compacted tlon' worlds, with adjusted motions and fixed relations ; the fourth is the appearance of low forms of vegetable and insensate life, rooted in and extracting its aliment from inorganic elements by a peculiar and unknown chemistry ; the fifth is free locomotive and sensitive life, in organisms fashioned from the common elements, but not rooted in them nor taking nutriment from them, but receiving its aliment from the pre viously formed vegetable fiber through a stomach, and in all its almost endless varieties, from the lowest to the highest, ex hibiting automatic mentality in greater or less degree ; the sixth is a discrete essence, eluding sense, and known only by effects it produces in the visible substance of matter — a spirit ual entity shrined in a highest type of sensitive, free locomotive organism, and exhibiting highest forms of mentality; a self- conscious, self -knowing, and self-governing subject, with powers of thought, feeling, and will purely subjective and personal. In a fitting order life crowns azoic ages and mind crowns life. Thus, with absolute diversity, there is pervasive and Divinity ends real unity ; each part having relation to and depend- lu unlty- ence on its immediate antecedent ; but at the same time each several part being distinct.

We are to treat of the universe — the earth and the stars, worlds and their inhabitants, inorganic and organic exist ences, their scope in time and space, originations and on going, and the processes and laws discernible in the vast com plex. The object is to find the facts which lie within our reach and as far as possible get an intelligent comprehension of them. Strictly avoiding the technicalities and frequently, to the common reader, obscure formulations which encumber the pages of learned scientific treatises, and with purpose employ ing a popular style, it will be our aim to give the last results of learned research as accurately as possible, not in the dry naked ness of a mere skeleton, but in tint and warmth of life. It will not be for the want of purpose if the pages do not glow and burn as they recite the wondrous story of the universe, itself 36 Studies in Theology. aglow from base to finial with marvels which surpass the most extravagant dreams of fancy. The proverb, " Truth is many times stranger than fiction," finds its best illustration in the simple facts of being which need but be known to ravish the thoughtful observer with won der and rapture. For the want of knowledge and of language we shall fail to tell the story, to reach the summit of the mighty theme, but you, reader, will grow strong and great as you strive to expand your thought and imagination to grasp it. It is the wrestle with great facts and thoughts which broadens and deepens mind and gives fiber to the best powers and possibili ties within us. We open to yon here the loftiest ranges. Try your pinions. Space Measures of the Universe. SPACE MEASURES OF THE UNIVERSE. Before we take up the facts of the universe for examination it may be well to note some perplexing questions foisted upon us by speculative philosophy. The first of these perplexities is as to reality of the alleged facts, or, perhaps, to be perfectly fair, the determination of what the reality is. What are the facts ? The common-sense view, and that which we accept, is that the universe is an aggregate of real objects, as they mi , Matter real. appear to our sense. There is a real earth — we our selves are real persons, and all the things about us, animate and inanimate, are real things, composed of real hard and fast sub stances, or having substance and reality of existence, objective and not merely subjective. Over against this so-called common-sense view is the theory that there are no such realities, but only a power which sup ports and renders permanent in our consciousness ideas to which we impute, by a law of mind, real objectivity to what we sup pose ourselves to perceive. The universe exists thus only in the mind and in the eternal energy which creates and supports the ideas. We name this theory, which is supported by many of the ablest and best men we know, not for the purpose of attempting to ref nte it, but simply to say that it is not the view held in this treatise. Nor do we denounce it as infidel or certainly not true. It may be true. We find ourselves unable to receive it. If true it makes nothing against the conclusions of this treatise. The facts of the universe are the same whichever view we take. In one case the facts are real as forms energized in the mind by its Creator reducing the universe to ideas, but still making it 38 Studies in Theology. real as a product. In the other case the facts are objects external, corresponding with ideas. If we are unable to comprehend the meaning or to suppose it is a correct ren dering of reality, we will be excused from accepting the ideal theory. To us there is a real objective universe such as we all talk about and imagine that we behold and touch and handle ; and of this universe we write. As our rendering of the facts will commit us to a temporal and spacial order we linger for a mo ment to call attention to these terms. The phrase, " the universe as it exists in space," demands that we should explain what we mean by space. Space is a relative term. It does not denote any real exist ence or thing, but some relation merely, as relative position, magnitude, figure, among real things. Were there no extended objects the term would be meaningless. Ideas have no north side, or east, or west, or south, no bulk or figure. Terms of space do not apply to them. Space has none of the properties of matter — as length, breadth, and thickness, extension, ponder osity, impenetrability, figure, size, color, taste, odor, primary or secondary qualities ; it has none of the attribute of spirits — no essence, no faculties ; it does not feel, or think, or wish — is not conscious. It has no properties of any kind — is nothing. It is invented simply to denote certain kinds of relations among figurable things. When we speak of the universe as it exists in time or as to universe in its temporal measures, the question arises, as it did time. with regard to1 space, " What do we mean by time ? " Again, we answer, " Time is a relative term." It denotes no real thing, but simply a relation among real things. It is sim ply an order of succession among changing realities. Begin ning, past, present, future, all terms of time, denote a relation Space Measures of the Universe. 39 among things which exist, have existed, or will exist, or imagi nary things arranged under ideas of relation. The universe in space means the magnitude and relations of things as to position. The universe in time means the uni verse as it has existed in and through an order of succession, or series of changing phenomena, as sunrisings and sunsettings. Were there no such phenomena of change the term time would have no meaning, and all its uses would disappear; there would be no past, no future, no sooner, no later, no long time, no short time — no time. The term is relative. It does not apply to the Eternal Being. It applies- to his acts which result in effects, not to himself. Time, like space, has none of the properties of matter and none of the attributes of spirit. There are relations of sequence among realities — order, succession. The term is invented to denote these relations — nothing more. Having no properties, it is nothing but an idea of order and suc cession. By the universe we mean the whole aggregate of things — whatever exists under conditions of time and space. universe— The definition of purpose excludes God. His rela- wliat? tion to the universe has treatment in another discussion. The universe may be viewed under three cardinal aspects, and must so be treated in order to get any proper conception. These diverse aspects sustain both a logical and actual re- Three aspects • ii • of the uni- lation to each other, a relation of temporal order verse. and conditioning grounds. They emerge in limina — one ante cedent to the other, and serving as the basis of the other. Thus the universe is discovered to be not merely an aggregation, but a system, all the parts of which cohere in an ultimate unity — a cosmos. 40 Studies in Theology. 1. We have first: The universe as mass of inorganic sub stance, called matter. 2. The organic universe. This comprises all forms of mat ter in which life appears — vegetable and animal. 3. The spiritual universe. This comprises orders of being who are endowed with personality. These divisions are natural, real, logical, and exhaustive. Each opens up a field of profitable study ; and we may venture the assertion, without which the proper understanding of the great theological problem — the problem of problems — the prob lem of the character of God and his end in creation — can never be solved or intelligently construed. Nature is God's highest exponent. The things which exist and are known to have existed, and facts with relation to them, furnish the most direct information we have as to the attributes and aims of the infinite Author. These are the subjects of our present inquiry. The Inorganic Universe. 41 THE INORGANIC UNIVERSE. Our investigation begins with the study of the inorganic uni verse. Logical propriety determines this order. The inorganic antedates and conditions the organic. . The full significance of this statement Avill soon appear. The inorganic exists for the organic. The inorganic universe comprises the vast masses of mere mat ter builded into worlds, and excludes all living beings. The mere word " masses of matter," or the other word " world," conveys no adequate idea of the inorganic realm of existence. If we pluralize the terms and add millions of worlds Masses of we still gain no real concept. If we vary the state- matter. ment into suns and moons and stars, and swell them into vast est number and spread them over what we are pleased to call infinite space, we still make no approach. Reality is definite. To get at reality the mind demands that terms have definite meanings, and that the exact meanings be perceived. Matter is one of the terms here employed. What is its meaning? It might seem unnecessary to pause over so simple a term where the meaning is supposed to be so manifest ; but simple terms are not always most easily apprehended, and, be guiled by their familiarity into the idea that we have their- meaning, we often employ them without any definite idea. at all. Matter is earth and rocks, water and air, the solids and fluids^ and gases which we touch and handle and inhale — " . Matter— what?' a something which has substance — is extended and imperishable; has weight and form and occupies space; has. the reality of existence and is not a mere idea. 42 Studies in Theology. Ultimately all matter — that is, all compounds or kinds of matter — is reducible to infinitesimal atoms, indivisible units ; each unit has the property of extension or so-called occupancy of space. There are but few persons outside of the ranks of the biolog ical students that have any idea of what is meant by the ex pression " an atom of matter." When the microscope is applied to the examination of living tissue, whether that tissue be of animal or vegetable life, it is soon observed that all living things are made up of minute bodies called " organisms." Ex perts in the various branches of biological research will also tell you that no essential difference can be distinguished between those cells which go to make up the sum total of animal life and those which give the vegetable its existence. These life cells, although wonders within themselves, are made up of mi nute particles called "atoms," which are so small that they must ever remain invisible to the human eye. Some critical reader will say, " If this last remark be true, how can it be proved that such infinitesimal particles as your so-called ' atoms ' exist? " To this query the reply would be that it is only when an untold number of these atoms unite themselves so as to form a single body, like the grains in a popcorn ball, that they be come at all visible, and then only by the best appliances that optical science has been able to furnish. This being the case, it is not an exaggeration to say that every little piece of matter which we are able to see is built up of millions upon millions of these atoms, which are so small that no mind can comprehend their minuteness, even when taken in aggregations of thousands. There are, of course, many differ ent kinds of atoms, such as atoms of carbon, hydrogen, oxygen, etc., each of which is believed to have its own particular size and weight. Then, too, they probably differ in shape as well as size. According to the specialists in this line they combine The Inorganic Universe. 43 together by mutual attraction, which is in some cases called co hesion and in others chemical affinity, according as the atoms are of the different elements. This being the case, it is easy to understand why myriads of these atoms of all sizes and shapes, fitted snugly one against the other, combine together in varying degrees of intensity to build up structures possessing all the va rious degrees of stability and solidity. . Some of the most won derful theories ever advanced on the atomic theory are by Sir William Thomson, the English scientist. In one of these arti cles he proves by three different trains of arguments that an atom cannot be greater than the one one hundred and fifty mil lionth of an inch nor less than one five billionth of an inch. Bishop Warren beautifully says : " Science finds matter to be capable of unknown refinement : water becomes steam, full of amazing capabilities ; we add more heat, superheat the steam, and it takes on new aptitudes and uncontrollable energy. Zinc burned in acid becomes electricity, which enters iron as a kind of soul and fills that body with a kind of life. All matter is capable of transformation, if not transfiguration, until it shines by the light of an indwelling spirit. . . . " When God made matter, so far as our thoughts permit us to know, he simply made force stationary and unconscious." (The best definition of idealism yet rendered.) " Join in the long and microscopic hunt for the atom, and if found, or if not found, to a consideration of its remarkable pow ers. Bring telescope and microscope. . . . Make the first search with the microscope ; we can count 112,000 lines ruled on a glass plate inside of an inch. But we are here looking at mountain ridges and valleys, not atoms. Gold can be beaten to the ii0\00 of an inch. But the atoms are still heaped one upon another. " Take some of the infusorial animals. Alonzo Gray says millions of them would not equal in bulk a grain of sand. Yet each of them performs the functions of respiration, circulation, 44 Studies in Theology. digestion, and locomotion. Some of our blood vessels are not a millionth of our size. What must be the size of the ultimate particle that freely moves about to nourish an animal whose totality is too small to estimate ? A grain of musk gives off atoms enough to scent every part of the air of a room. You detect it above, below, on every side. Then let the zephyrs of summer and the blasts of winter sweep through that room for forty years, bearing out into the wide world miles on miles of air, all perfumed from the atoms of that grain of musk, and at the end of the forty years the weight of musk has not appre ciably diminished. Yet unaccountable myriads on myriads of atoms have gone. " Our atom is not found yet. We will pass in review the properties with which materialists preposterously endow it. It is impenetrable and indivisible, though some atoms are a hun dred times larger than others. Each has definite shape — some one shape, some another. They differ in weight, in quantity of combining power, in quality of combining power. They combine with different substances in certain exact assignable quantities. Thus one atom of hydrogen combines with eighty of bromine, one hundred and sixty of mercury, two hundred and forty of boron, three hundred and twenty of silicon, etc. " The atoms of luminif erous ether are infinitely more diffused ; its interactive atoms can give four hundred millions of light waves in a second. And now, more preposterous than all, each atom has an attractive power for every other atom of the universe." * Masses of matter are accumulations and collocations of these minute substances until they acquire bulk and size, become vari ously compounded and take on specific conditions, and are differentiable as solids, liquids, gases, clay, sand, rocks, metals. When they acquire great proportions and are separated from other masses, so as to take on an economy of * Recreations in Astronomy, pp. 241, 256-268. The Inorganic Universe. 45 motion peculiar to themselves, these large masses are called worlds, and collectively they are the inorganic universe — the all of matter. The immediate object we have now in view is to put our selves in possession of some idea of the vastness of these masses of inorganic substance. Having gained this point, vastness of our next effort will be to find out the economies per- tne universe- vasive of them and determining their constitutions and the ends for which they exist, thus discovering the powers of the Being who has made and ordered them, and yet deeper, in their ends or uses discovering the character of the mighty Maker. It is thus we study and measure men. Why shall we not bring the same method to the study of the Maker of men and of the universe ? 46 Studies in Theology. MASSES OF MATTER. Worlds : How shall we get hold of the idea of a world ? Not bv ringing the changes on the word. We gain noth- Worlds. J ° ° TO . , Al ing by this. We must examine and measure the thing itself — see it on all sides, measure it in detail, build it inch by inch until it stands forth in our thought as a whole, as some city or monument that we visit does. Until we are at the pains to do this we delude ourselves with mere sounds with out ideas, and fail of grasping meanings. In studying worlds as inorganic masses let us begin with the world we know most about — the world on which we live and from which we make our observation of other worlds. The single object we aim at now is to get a concept of the bulk or mass of world matter of our own world and other worlds known to exist. Take the earth as a primary study. The earth is now known to be a spherical body — an oblate spheroid, not com- pletely round. Its longest diameter is proximately eight thousand miles. Its substance is wrought together in solid mass, that is, contactual or continuous mass, of hard and fluid matter reaching from its external surfaces inward to the center. Its surfaces present to the eye the appearance of a continuous plain, furrowed by river beds and ocean basins, and corrugated by ranges of hills and mountains, and measuring two hundred million square miles of surface, the greater part being water, only fifty million, or one fourth, land. Try to think of this mass. Tax your faculties. Ascend some highest mountain and get a wide view. Take passage on one of the great steamships. Travel half a thousand miles each Masses of Matter. 47 day for many days to cross from shore to shore. Take the train on the great railways and travel the continents for Aveeks and months together. Pass from kingdom to kingdom and country to country. Spend years at it in continuous going ; ex haust life itself in the pursuit. At the end you have seen but little" narrow ribbons of its surface. The amazement grows upon you. When yon return you talk of the great cities you have visited, the vast cathedrals and temples and tombs you have seen, the lands you have passed through, the seas you have navigated, but you have not seen a thousandth part of the surface which turns to the sun every twenty-four hours ; no man ever did or could in the longest lifetime. Take Pike's Peak, that atomic feature of a single range of mountains, only a speck in the landscape ; shave it Pike's Peak off at the base, as you would remove a mole from the face or a wart from the hand ; there is more material in that single speck than has been used in all the constructions of man from the beginning of the world to this day ; yet com pared with the globe itself it is less proportionately than a mustard seed upon its summit is to its mass. If there were not another Avorld in space the earth itself would be the ever lasting wonder of men and angels, viewed simply as a mass of inorganic matter, the only aspect in which we are now studying it. Further on we shall see its deeper lessons. Standing upon the earth and anchored to it by a fatality which we have no power to overcome, we look upward How tne uni_ ^ ' A verse appears and away from it. What do we behold ? To the in daylight. seeming, in the daylight hours, Ave gaze out into an infinite void. From horizon to horizon there is but a single speck to arrest our gaze, a small luminous object, round in figure and dazzlingly effulgent, but less than the dome on our capitol, not larger than a carriage wheel, a disk of burnished gold, twenty inches in diameter; we name it the sun. It is a fixture. Each day it 48 Studies in Theology. appears on the eastern horizon at a given minute, passes over our heads and disappears behind the western horizon. Night shuts in. A figure of similar form and size, attended by a multitude of brilliant points, comes out to view. The sky is full of them ; we name them moon and planets and stars. What are they ? Let us keep in mind that for the present our sole inquiry is, What are they as objects, specifically as to their dimensions ? We do not now raise questions as to their relations, functions, and economies. These points are in abeyance for the present. That they are real objects and not mere illusions we know. They are given merely to the sense of sight. We are separated from them by impassable space. They seem to be merely luminous disks of small diameter and smaller points. So for ages and until a recent date they were thought in reality to be. The discovery that they are not such is one of the most won derful achievements of the human mind. They are now known to be vast masses of matter-worlds, Night won- some smaller, many of them, indeed, all of them, but less than half a score, almost infinitely larger than the earth which Ave inhabit, and composed of precisely the same substance which our feet press and our hands handle. In considering them as masses with reference solely to the ex tent of the universe, Ave must think of them as to the measures of space which they occupy, which involves the distances they are asunder, as well as the spaces which they fill. So long as men were dependent on mere unaided vision these were problems of impossible solution. Ages of specula tion left the mystery untouched. It is the wonder of wonders that it did not forever remain so. The magnificent concep tion of Copernicus, formulated by Kepler ; the discovery by Newton of the great law of gravitation, possibly first suspected by Kepler, but finally formulated by the great astronomer Masses of Matter. 49 whose name it bears, and ascribed to an accidental discovery ; the similarly accidental discovery of the lens ; finally, the spec troscope, have jointly furnished the key by which the mystery of the sidereal universe has been resolved. Newton gives us the law which lias been found to determine and regulate the relations and motions of all worlds. Copernicus has given us the solar system. The lens multiplies the power of the eye so that we can carry our observations many thousand times further into space than was possible to unaided vision, and so discover universes- a thousand — many thousand — times greater than that before known. With the aid of these clews we begin our investiga tion. Some mention has already been made of our earth home, as to its magnitude. Of it we have a tolerably clear conception as a vast globe but measurable by imagination. It is found to be a member of a system, or small group of worlds which takes the name of the central body around which it and the other mem bers move, the solar system. 50 Studies in Theology. THE SOLAR SYSTEM. It is natural and proper that we should begin our investiga tions with a more careful survey of this system. The study will prepare us for the more extended survey of other systems out beyond to the rims of the universe as noAV known. The solar system comprises our sun and its retinue of nine or ten planets and their satellites, with a group of asteroids, sup posed by its location to be fragments of a disrupted planet, numbering two or three hundred, not visible to the eye, or possibly minute bodies never massed into a greater globe. THE SUN. The sun is the fixed center of the system around which other members revolve in periods of definite but longer The sun. , . ~ . or shorter time. It is proper that we should begin the survey by first calling attention to that amazing body. To the eye it seems to be infinitely small compared with the earth ; in reality it is discovered to be almost infinitely large. As stated already, it is found to be a fixed body ; that is, to be sta tionary Avith respect to the other members of the group, and indeed relatively to the other stellar systems. If it has any orbital movement that fact is not ascertained with certainty, and if a fact, it does not change its relation to other stellar bodies, but must be in some vast revolution through periods of unimagina ble time, in which all other bodies of the universe move in har mony around some as yet unascertained center. It is known, hoAvever, to have an axial motion, to revolve about its OAvn center in the same direction Avith the other members of the group, completing a revolution in every twenty-six days, about six times the velocity of our axial movement. The Solar System. 51 We have already hinted at the magnitude of this amazing body. It is important that we should further ponder this r The govern- point on many accounts. It is the center of the sys- Ins b0<&- tem. It has sovereign relation to the other members. Its at traction governs them all and determines their movements, an chors them in bounds which they cannot pass. It is king over a vast region of space where it holds absolute dominion, not sim ply over its own planetary children and subjects, but against the invasion of all other world systems. There, rooted fast in the infinite void, it holds absolute empire. There it burns and shines forever with undiminished splendor. Nothing is more amazing than this fact. Neither its brigthness nor fervors ever appreciably vary or wane ; the emblem of its Author, " the same yesterday, to-day, and forever," or until its appointed time ; its flame so dazzling that no eye can gaze upon it for a moment, flooding immeasurable realms of space through immeasurable ages with unfading brilliancy. Matchless monarch ! But we were to speak of its magnitude. It seems not larger than a carriage wheel — hardly so large. We wonder at its shining. Let us try to get some idea of its real size. It has been meas ured and weighed. There is no uncertainty about the accu racy of the result. We have but to try to grasp it. We have alluded to the planets, satellites, and asteroids, or worlds like our earth, most of the planets larger, the others smaller ; we have some conception of the earth. The sun is seven hundred times larger than all of them put together, or 1,300,000 times larger than the earth taken alone. How shall we grasp this amazing magnitude ? We must re sort to illustration ; mere statement fails to give any Earth magni. idea. The earth is 8,000 miles in diameter; the tude- sun is 880,000 miles in diameter. Still we fail to get an idea except that one is much larger than the other. Let us try again. Suppose the sun a hollow sphere with a 1,000-mile 52 Studies in Theology. thickness for the shell. Imagine an opening into it 8,000 miles in diameter, a great auger hole 8,000 miles across, further than from San Francisco to the Bosporus or Constantinople, across the continent of America, the Atlantic Ocean, and the continent of Europe. Now collect 1,300,000 worlds the size of ours and drop them into this immense cavern, and they will only fill the void ; or, instead of this, drop our earth in and sun magm- ^ ^ settle at the center of the cavity, and then drop tude. our moon in and let it take the precise position with relation to the earth which it now occupies, 240,000 miles from it, and now let it commence its accustomed revolution ; the orbit it will describe will be equidistant from the earth and the inner surface of the shell. " There is no point on the surface of the globe that unites so many awful and sublime objects as the top of Etna, and no imagination has dared to form a description of so glorious and magnificent a scene. The body of the sun is seen rising from the ocean, immense tracts of both sea and land interven ing ; the islands of Panara, Alicudi, Lipari, Stromboli, and "Vol cano, with their smoking summits, appear under your feet, and you look down on the whole of Sicily as on a map, and can trace every river through all its windings from its source to its mouth. The view is absolutely boundless on every side, so that the sight is everywhere lost in immensity. Yet this glorious and expansive prospect is comprised within a circle about 240 miles in diameter and 754 in circumference, containing 45,240 square miles, which is only ^^^ part 0f the surface of the sun; so that fifty-three million seven hundred and seventy-six thousand six hundred and eight landscapes, such as beheld from Mount Etna, behooved to pass before us be fore we could contemplate a surface as expansive as that of the sun ; and if every such landscape were to occupy two hours in the contemplation, as supposed above, it would require twenty- The Solar System. 53 four thousand five hundred and fifty-four years before the whole surface of this immense globe could be in this manner surveyed." * It has been already stated that the solar system which we are now considering comprises a definite group of worlds under one group of economies, constituting a system within it self. The sun belongs to the greater universe sys- ° ar sp m" tem. The other members of the group are called planets. There are nine of them, varying in diameters from Vulcan, which is the least, to Jupiter, which is the largest. Besides there is a cluster of very small bodies, occupying a place where there ought to be a tenth planet. These are known as asteroids or planetoids. There are several hundred of them already known, and they have an economy of motion among themselves. They are supposed to be fragments of a disrupted planet, and collectively would make a body about the size of Mars, which is the planet next them. The planets revolve about the great central member of the sys tem — the sun — in fixed orbits of various dimensions, and with varying velocities and on shorter and longer periods. I lfl.HGtS. They also have an axial revolution in varying time. The orbital revolution determines the length of their year, while the axial determines the length of their day. The extremes are great — reducing the day in some cases to ten hours, and carry ing the year up to two hundred and eighty of our years$ and in some cases reducing it to two thirds of ours. The planets in turn become 'centers of inferior groups, called satellites. The number varies. One, at least, is known to have eight. Our earth home has one. Of these subsidi- pianet3 Be- ary bodies between twenty and thirty have been dis- come oenter3, covered ; some of them only inferior in size to some of the smaller planets. The entire solar system — sun, planets, satellites, and asteroids *Dick, Celestial Scenery, p. 214. 54 Studies in Theology. — comprises several hundred bodies, or if we call the planetoids one, about forty, which must be classed as lesser and greater worlds, under economies peculiar to the system, and amid ex treme complexity of motions, orbit within orbit, maintaining absolute harmony and subserving various functions of useful ness and grace to the life which pervades the system — a beauti ful and sublime universe within itself. In fact, it is but one of innumerable similar systems overspreading illimitable spaces, making the vast system of worlds of unknown extent. As this system, best known to us, may serve as a key to all other outlying systems, it will be of advantage if we linger for its yet more particular study. Keep in mind that the one thing we have in view now is to get a clear concept of the space measures of the universe ; and in order to that we now seek to get an idea of the space meas ures of our own solar system. It has been already stated that the planets are grouped about the sun at various distances, and that they describe orbits of Ararious diameters in regular but differing periods of time about their common center. Our search now is to find their respec tive distances from the sun. VULCAN. Vulcan, of whose existence even we had no knowledge until recently, and which is even yet in dispute, is the innermost and smallest of the planets. It is located and has its mean orbital vuican, dis- path about fifteen million miles from the sun. Its tancefrom . , the sun. motions, orbital and axial, are both still undeter mined. Its distance only is proximately ascertained. It is the shortest distance in celestial measurements except in the case of satellites. But it will be of service to endeavor to form some concept of this amazing distance before we approach the larger measures of the solar system, but especially before we grapple The Solar System. 5£ with the still greater spaces in the sidereal systems. Fifteen million miles — nothing to infinite space ; but yet all that we know of measurement is as nothing compared with it. Eight een hundred and ninety of our world, if placed in line, would find room between Vulcan and the sun, or seventy-five moons, each separated from the other as far as our moon is separated from us, could stand in line to cover the enormous space. mercury. Mercury, next in order, is better knoAvn, and yet it is seldom seen without special search Avith an instrument. Its place and habits are familiar to astronomic science. Its orbit lies about thirty-seven million miles away from the sun, or twice gize ai8tanee and proximately a half as distant as Vulcan. Its from the sun. motions and magnitude are measured and determined. It is thirty-one hundred miles in diameter, and its orbital revolution requires eighty-eight days. Its axial revolution is about the same, but only minutes less than that of our earth. VENUS. Pursuing our course outward, we next come to Venus. This planet is universally regarded as the most beautiful venus the of the group, and, indeed, unsurpassed in the entire celestial scenery, competing with our moon for the title " queen of heaven." Our nearest neighbor, it is also nearly of the same dimen sions of our earth, having a diameter of seven thousand seven hundred miles. Its position is about sixty-eight million miles from the sun. Its orbital revolution is accomplished in tAVO hundred and twenty-five days, a little less than two thirds of the time required by our planet, while its axial revolution occupies twenty-three hours and some minutes, making its day practically the same as our OAvn. It is now known to have an 56 Studies in Theology. atmosphere of volume nearly equal to that of our earth, and its light is radiantly beautiful. earth. The earth comes next in the order of distance. It, as is well known, is about eight thousand miles in diameter, and moves in an orbit of proximately ninety-two millions of miles from the sun and about twenty-five millions exterior to that of Venus, with an axial movement nearly identical with that planet ; its day being twenty-four hours and its year three hundred and sixty-five days and about one quarter. We have become so well acquainted with the facts and economies of our earth home that it makes easy many matters concerning the general universe system that otherwise might have remained insolvable. For the first time we encounter the satellite fea ture of the universe system in the moon which attends our earth, and which, because of its near neighborhood, is so charm ing a companion. It, like the planets, shines with a reflected light. Its distance from us is only an average of two hundred thousand miles, and its size is only about one fiftieth that of the earth, or only about two thousand miles in diameter. MARS. Next us and exterior is the planet Mars. The distance which separates us from it is, as we would expect, greater, being about Mars the erst forty-seven million miles, and placing it remote from exterior ° planet. the sun more than one hundred and forty million miles. The observed order in the interior planets of increasing size here is not sustained, the diameter of Mars being only four thousand one hundred miles, just more than one half that of the earth. Its axial motion is nearly identical with that of the earth and of Venus. Its day is a few minutes longer than ours, being twenty-four and a half hours ; but there is a great leap The Solar System. 57 in its orbital movement, its year being six hundred and eighty- seven days, nearly twice the length of ours. As we would ex pect, it is attended with two satellites to our one ; but they are less than our moon. ASTEROIDS. Still further outward, next to Mars, and at the distance of about two hundred million miles from the solar center, where according to the analogies of the system, a planet A ruPtured should be found, we come upon a large group of planet. several hundred planetoids of very small size — only a few miles in diameter the largest of them, and not collectively, so far as yet knoAvn, equal in mass to the smallest planet. They are generally assumed to be fragments of a disrupted world, but with no certainty of the truth of the conjecture. JUPITER. Jupiter the magnificent is next in order. His position with relation to other bodies in the system is midway between the asteroids and Saturn, the asteroids being scattered Tnemagnin- over a space between two and three hundred millions cent- of miles from the sun, and Saturn being eight hundred and eighty-one million miles. The place of Jupiter is four hundred and fifty-seven million miles. He is justly styled the magnifi cent, being the largest and most brilliant of the solar group. His diameter is about one tenth that of the sun, being eighty-seven thousand miles — ten times that of the earth ; and his volume being equal to one thousand three hundred of our world. He is attended by four moons of varied dimensions, which are eas ily seen through a telescope of moderate power, some of them being visible at times to the human eye. One of the moons is larger than the planet Mercury. Bishop Warren, in his captivating and most suggestive and instructive volume, liecreations in Astronomy, says: "If 58 ' Studies in Theology. the Jovian system were the only one in existence it would be a surprising object of wonder and study. A monster planet, eighty-five thousand miles in diameter, hanging on npthing, re volving its equatorial surface forty-five miles a minute, holding four other worlds in steady orbits, some of them at a speed of seven hundred miles a minute, and the whole system carried through space at five hundred miles a minute." * Of this amazing body one of the most amazing facts is the rapidity of its axial revolution, which is accomplished in less than ten hours, making its day but tAvo fifths that of the earth, and requiring its equatorial surface to move twenty-four thousand miles an hour. Its orbital revolution is accomplished in about twelve years, and its motion is at the rate of nearly five hundred miles a minute. SATURN. Continuing our journey outward from the great solar center, Ave find ourselves, at the end of eight hundred and eighty million miles, four hundred and twenty-three million miles away from Jupiter, counting Vulcan as one, and the asteroids, an eighth satum the group — the Satiirnian. Saturn, with his rings, has unique. eyer keen regarded as the only rival of Venus for beauty. Seen through a great telescope it is the most fascina ting and wondrously beautiful body in space. To the eye it lacks the brightness of Jupiter and does not compare with Venus. It is only less than Jupiter in size, being in mean diam eter about seventy thousand miles. For a minute description of this unique body see any Avork on astronomy. The history of research on the subject is exceedingly interesting, but is not in the line of our object in this discussion. The Saturnian body, as stated, is proximately seventy thousand miles in diameter. The rings are separate from the body at distances ten thousand miles first ; ring second, eighteen thousand miles ; * Recreations in Astronomy, p. 167. The Solar System. 59 then a gap of near two thousand miles ; then a third ring of ten thousand miles wide ; then the eight moons in exterior orbits. The whole presents the most sublime spectacle imaginable. The axial revolution of Saturn is nearly the same as that of Jupiter, being a few minutes more than ten hours. Its year is about twenty-nine and a half of our years. URANUS. Still continuing our journey outward at a point beyond Sat urn nearly a billion miles, and from the sun 1,800,000,000, or one billion eight hundred million miles,* we come to Uranus, more than double the distance of Saturn, by far the largest interval between any of the planets. It was long The wonder J r ° ofitsdiscov- supposed to be the outermost planet of the solar ery. group. It lies too deep in space to be seen by the unaided eye, but is easily seen by the aid of an ordinary telescope. It is known to be attended by four, with probability of six, moons. Its ascertained diameter is about thirty-two thousand miles, four times that of the earth, and not quite half that of Saturn. Its distance is too great to furnish data for calculating its axial revolution, but its orbital movement is well known. It requires eighty-four of our years to complete one revolution. Its orbital velocity is proximately — exactly, in fact — two hundred and fifty-two miles per minute throughout its long and solitary journey round the solar center. We have reached a distance, the measure merely of a radius of an amazing circle, which makes the mind reel and stagger in the contemplation. NEPTUNE. Once more we start on our outward journey. Phenomena discovered in Uranus — disturbances of motion — lead to the conjecture that there must be lying out beyond it still another * French method of enumeration. 60 Studies in Theology. planet, so accurately has science calculated the laws of motion The outer- hi these remote spaces. Careful calculation deter- most planet. mine(j aD0Ut at what point in the immense periphery of space the disturbing body must be located. Turning the telescope to that point the unknown stranger was soon discov ered, and Neptune was registered in the brilliant galaxy. He retains his heraldic honor up to date of being the eldest of the solar progeny — the outermost and most ancient of the planets. His place is found to be 2,775,000,000 miles from the sun, about 1,000,000,000 miles from his nearest neighbor and next of kin. Vastness of the Solar Group. 61 VASTNESS OF THE SOLAR GROUP. Three points deserve special attention : first, the magnificent scale of the system as to spatial extension or domain. The do main of the solar system, as described by the orbit of Nep tune, is an area of 5,550,000,000 miles in diameter, or, if we allow it a share of one half the space between it Measures of the solar sys- and its nearest solar neighbor, a domain of tem. 40,000,000,000,000 miles in diameter. The planets under its immediate control are within the first-named inclosure in the space circumscribed by the orbit of Neptune. Within this inclosure we have seen that the planets describe orbits within orbits. Within this area these great globes perform their wonderful evolutions. How shall we get a concept of these amazing distances and amazing magnitudes ? To do so we must employ a measure of which we have some conception. We might employ the velocity of a cannon ball — twelve miles in a minute — but it would scarcely help us. Let us use a more familiar measure, the average speed of an express train or a locomotive — thirty-eight miles and a fraction in an hour. This measure has two advantages : it is perfectly comprehensible, and it requires just three years to make one million miles. Now we seek to get an idea of the domain inclosed in the orbit of Neptune or of the solar system. To do this let us in imagina tion project a railroad from the sun to Neptune, and place our locomotive on it and start it from the sun at a speed of thirty- eight and a half miles an hour, and suppose it to run continu ously ; we should have this result : at the end of forty-five years we should cross the orbit of Vulcan, that is, the path the planet travels around the sun ; at the end of one hundred and eight 62 Studies in Theology. years we should cross the track of Mercury ; at the end of two hundred and four years we should cross the track of Venus ; at the end of two hundred and eighty-five years we should pass outside the orbit of the earth ; at the end of four hundred and twenty-six years we should cross the track of Mars ; at the end of one thousand four hundred and fifty years we should pass beyond the orbit of Jupiter ; at the end of two thousand six hundred and seventy years we should cross the path of Saturn ; at the end of five thousand four hundred years we should pass the orbit of Uranus ; and at the end of eight thou sand three hundred and twenty-five years we should come to the orbit of Neptune. Had Adam started on the journey at his birth he might now, according to the most liberal chronol ogy, just be coming to the end of his ride ; and if now he would reach the nearest of the fixed stars he must extend his ride sixty million years more. Such is the measure of the em pire of our solar system as determined by science. If now we consider the magnitude of the bodies composing the system we have this result : of the whole number two are only about half the size of the earth, two are nearly its size, and four are many times larger, the largest being one thousand three hundred times as great. Who can reflect on the effulgence of solar bodies without feel ing aAve of the wondrous power which feeds their fires through infinite ages, so that their luminosity remains undiminished, shining on and flooding the infinite abyss while generations and eons come and go as transient dreams ; ever the same, keeping their silent vigils while decay and death destroy all sublunary existence ; suns sending messages to kindred suns over spaces so remote that the fleet courier reaches his destination only after the flight of millions of years ; lighting up the way of planets and their freightage of life as they revolve in their great circuits Vastness of the Solar Group. 63 at a velocity a hundred times greater than the flight of a cannon ball ! And these amazing velocities, who can think of them without terror of the power which impels and guides them, rushing along their unstaked paths so that they do not deviate an inch in all their course, and coming to their time to the fraction of a second in a million years ? Surely, " The heavens declare the glory of God ; and the firmament showeth his handiwork. Day unto day uttereth speech, and night unto night showeth knowledge. There is no speech nor language, their voice is not heard [they have no voice — make no sound], yet their line is gone out through all the earth, and their Avords to the end of the world." It is a curious fact of planets that there seem to be fixed ra tios with respect to their distances, volumes, and densities, and that this should have been discoATered. "The pri- Facts of the mary planets show a progressive increase of bulk Planets. and diminution of density from the one nearest to the sun to the one most distant. With respect to density alone we find, taking water as a measure and counting it as one, that Saturn is |f, or less than half ; Jupiter, 1-fa ; Mars, 3^3T ; Earth, 4J ; Venus, 5-fi-; Mercury, 9-fa, or above the weight of lead. Then the distances are curiously relative. It has been found that if we place the folloAving line of numbers, 0 — 3 — 6 — 12 — 24 — 48 — 96 — 192, and add 4 to each, Ave shall have a series denoting the respect ive distances of the planets from the sun. It will stand thus : 4 — 7 — 10 — 16 — 28 — 52 — 100—196 Mercury, Venus, Earth, Mars, Asteroids, Jupiter, Saturn, Uranus. It will be observed that the first row of figures goes on from the second on the left hand in a succession of duplications or multiplications by 2. It was remarked when this curious rela- 64 Studies in Theology. tion was first detected that there was the want of a planet cor responding to 28 ; the difficulty was afterward considered as in a great measure overcome by the discovery of a group of plan etoids revolving in the space between Mars and Jupiter. It is a still further curious fact that the distances bear an equally in teresting mathematical relation to the times of their respective revolutions round the sun. It has been found that, with respect to any two planets, the squares of the times of revolutions are to each other in the same proportions as the cubes of their mean distances — a most surprising result for the discovery of which the world is indebted to Kepler. Sir John Herschel Avell observes : " When we contemplate the constituents of the planetary system from the point of view which this relation affords us it is no longer mere analogy which strikes us, no longer general resemblance among them, as individuals inde pendent of each other, and circulating about the sun, each ac cording to his own peculiar nature, and connected with it by its own peculiar tie. The resemblance is now perceived to be a trne family likeness ; they are bound up in one chain ; inter woven in one web of mutual relation and harmonious agree ment ; subjected to one pervading influence which extends from the center to the furthest limits of that great system, of Avhich all of them, the earth included, must henceforth be re garded as members." * A better knowledge of the constitution of the sun, which may some time be obtained, may explain the curious phenom ena ; at present they must be viewed as remarkable facts. The orbital velocities of the planets have a similar proportion. The motion in miles per second is as follows: Mercury, 29.55; Ve nus, 21.61 ; Earth, 18.38 ; Mars, 14.99 ; Jupiter, 8.06— here Ave perceive the gap occasioned by the absence of a planet replaced by the asteroids— Saturn, 5.95 ; Uranus, 4.20 ; Neptune, 3.36. f * Taken from Vestiges of Creation, pp. 8, 9. f Warren, p. 105. Economies of the Inorgahic Universe. 65 ECONOMIES OF THE INORGANIC UNIVERSE. The economies of the inorganic universe are not less amazing than the magnitude of the bodies which compose it and the semi-infinite spaces Avhich separate them. If we are drowned in wonder in the contemplation of this, Avonder and awe are lost in admiration and reverence as we think of them. If mere bulk and brilliancy and breadth overwhelm us, what shall be our emotions as we behold the harmonies of the heavenly bodies ? There are four aspects in which they are to be contemplated under the general concept of economies : (1) They are hung upon nothing out, in, and over the empty spaces — Economies of founded not even upon air, but upon emptiness — the system. void. Every building hath foundation, but what upholdeth the pillars of the sky ? Above, beneath, around, infinite void — neither bracket, nor brace, nor support; ponderous with infinite weight, but suspended on nothing. (2) The seeond as pect is their absolute fixity. We refer now to the stellar bod ies — the great solar centers, and with reference to their relation to each other. We do not know that they have any motions except axial. They are known to revolve, and they all move in harmony with unchanging relation over immeasurable fields of space. But we do know that, whatever their motions, their special relations to each other are fixed. The " bands of Orion " are not broken, and the constellations are not variable. Each star occupies its exact place, more absolute than if spiked in framework of steel. (3) The third aspect is that of the motions of the planetary bodies. If the stellar bodies are fixed the planets. are in perpetual motion. Two things amaze us, the unalterable QQ Studies in Theology. courses they pursue and their velocities. They are endowed with two motions, one axial, the other orbital; one through space, the other in space. To these we call attention. These motions, both one and the other, are known to be absolutely reg ular ; but each body has its own rate of motion, both axial and orbital. For the illustration we select one or two examples. Our first example is taken from our own earth home. It makes a complete revolution once in twenty-four hours, which The earth mo- makes our day and night. If this were its only tions on its . axis. motion it would be as fixed in space as the sun itself, and would never, except in its surfaces, change its rela tions to its sister planets or to any of the fixed solar bodies ; there would be no wandering stars. The velocity of its revolution is such that we are borne along through space at the rate of nearly seventeen miles in a minute, or once and half the speed of a cannon ball, yet never feel the motion. Its orbital motion, which makes our year — that is, its motion around the sun— is still more wonderful, being at the rate of a fraction over seventeen miles in a second of time, or nearly seventy times faster than a cannon ball. All the planets have corresponding but less and greater velocities both axial and or bital. Their motions are absolutely regular, passing in their courses over the same spaces in precisely the same time. These amazing velocities transcend imagination. In our system, whieh is doubtless in general features similar to all solar systems, the planets have their satellites, which in turn revolve in their or bits around them as they revolve around the sun. Each mem ber of the system has its fixed place and absolute orbit, orbit within orbit. Each pursues its strict and invariable course with strict and invariable velocity, never crossing the path of any other or trespassing on its domain ; each attracting every other, but producing no disturbance ; all moving in absolute harmony. Could we occupy a fixed position, and were we endowed with Economies of the Inorganic Universe. 67 power of vision that would command the entire area occupied by the Avhole universe, and could we see each world in its act ual size and precise relations of distance to every other, how amazing the spectacle we should behold ! — the immensity, the vastness, the complicate but absolute harmony ; the great suns motionless or changeless in position ; the planets careering in countless orbits Avith varied but inconceivable velocities in every direction, course cutting course ; their satellites rushing on their ways in lesser spheres in reverse and counter courses, like a chaos of burning wheels, but all working with the harmony of a perfect machine in which no wheel is astray and no cog dis placed ; the great clockwork of the universe measuring out its time to the thousandth part of a second in millions of ages. (4) The next aspect we note is the permanence of the com plicate system, the undiminishing persistence of the mysterious force which holds them in existence and conserves their relations. Atoms have formed new alliances, have been compounded and recompounded, have now been collocated in one way, now in another ; may have changed places and relations by the breadth of the globes which they compose ; but thWe is no evidence that a single atom has perished or of any power which works to their destruction. There is evidence of an economy of growth and development, but not of increase of substance. Planets have their bulk and evolutions from one stage to an other, their changes from chaos to maturity and decay, but as far as is known do not disappear. Their changes indicate other uses and are for ulterior ends. It is supposed that as the universal system had in some remote past a beginning, which is among the demonstrable facts, there will come a time when it will have an end or transformation into anew and higher form for new and higher uses, and that there are signs of such a change ; but if such a change shall come it must be at some far distant future and by the same power which started it on its amazing career. 68 Studies in Theology. MODE OF MAKING THE SOLAR SYSTEM. Before we leave our survey of the solar system for the wider sidereal um- survey of the universe we ask attention to the proc- yerse- ess of its erection. It is now certain that the great Builder has consumed immeasurable ages in its construction ; that not only is it built on a scale of inconceivable vastness and with consummate skill, but also that the work has been carried forward according to a perfect method pursued through infinite reaches of time. First the suitable material, then the structure. Geology discloses the fact that at an inconceivably distant pe riod the foundations of the earth were laid. There is abun dant evidence that with respect to the earth, which serves as a clew to the whole process of world building, its first condi tion was that of a molten mass, or, earlier still, mere primor dial elements. In ages — how long cannot be ascertained — it assumed the form of a molten mass refrigerated and solidified or crusted over on the surface with probably a yet remaining molten interior. When the solid crust was formed a secondary surface began to appear in the form of stratified deposits. By means of these we are able to trace with scientific certainty and proxi mate accuracy its subsequent history up to date. The agencies at work in producing superficial deposits over the earth's sur faces are well known, and the rate at which the deposits are made is proximately ascertained. No one who has studied the problem doubts that millions of years have been consumed in piling up these immense stratified accumulations. But if now we push our researches further back, as we are able to do, to the period when the earth was a molten ball, Mode of Making the Solar System. 69 who shall tell us of the eons which elapsed during the process of the formation of its refrigerated crust ? And if, again, adopting the nebular theory, to which all the facts seem to point, Ave push our researches back to the universal fire mist during which solar foci were determined which divided the infinite mass into segregated parts, and watch the process by Avhich worlds were evolved, how infinitely our line is extended ! By supposition we have reached the point when the mass of which our solar system is formed was disseminated over the space which extends midway to neighboring solar foci — half way to Cygni. Then, atom by its law rushing to its kindred atom, the process commenced. The law of attraction drew the atoms toward a common center, imparted rotary motion, developed the law of centrifugal force. Condensation, in ages how long, reduced the as yet undivided mass, revolving around the point which is now our sun, to a globe the dimensions of the orbit of Neptune, when the increasing velocity threw off or dislodged from the parent mass a portion sufficient to make that planet, the oldest and first born of our planetary sisters. Then again, in ages how long, when the mass had condensed to the orbit of Uranus, by a similar dis- lodgment that planet commenced its orbital movement, held like the other in its orbital path by the two forces, centripetal and centrifugal, which forever determine its place, and so down through till each planet in turn assumed its place and the system was completed — the solar center still reducing to its present compact form. If this rational but undemonstrated theory be true the dawn of creation, which is the birthday of time, is pushed back to a date compared with which geological eons are but transient moments. 70 Studies in Theology BEYOND THE SOLAR SYSTEM. But this rough sketch of the solar system is but the first page of the marvelous revelation. For the solution of the matchless problem we must extend our researches into remoter regions of space. Looking up into the heavens, we discover beyond the domain of the solar system, by unaided vision, innumerable other bril- Numherofthe liant objects, now known to be worlds. There are, visible stars. in(jee^j ^ut aDOut six thousand of them visible to the eye — less than half that number visible from any one point at one time. These are discovered to be absolutely fixed bodies, that is, to maintain unchanged relations to each other and to our solar center. This fact, together with their self-luminous character and vast magnitudes, determine them to be of the order of suns and not planets, and warrants the idea that they, as our sun, are centers of groups of worlds resembling our solar system. Science determines with accuracy that these vast solar centers are distributed at points proximately equidistant over the field of space, the measure of separation being from twenty to thirty millions of millions of miles. The depth to which the eye carries us is found to be through twelve of these side real measures, that is, the remotest star visible to the eye is determined to be about twelve times as far as the one nearest to us by actual measurement. It is found that the light and apparent size of the bodies diminish in the ratios of their dis tances, until they finally fade out and we find ourselves in a pale milky zone in which no individual objects are discernible, beyond Avhich is darkness. Whether these remoter depths are inhabited by farther away suns and systems the eye fails to Beyond the Solar System. 71 tell us — the dim light discoverable beyond is suggestive merely. But let us now return to examine more carefully what we have thus briefly stated. The area described by the penetrating power of the eye is seen to be a sphere the radius of which is, say, 360,000,000,000,000 to 500,000,000,000,000 miles. This, of course, transcends all power of conception ; illustration may aid us. Light, at a speed of 12,000,000 miles in a minute, would traverse the Distance . measured by radius in 80 years or less, or the diameter of the sphere light. in about 160 years ; but a velocity of 12,000,000 miles a min ute simply stuns us and conveys no idea. Let us return to the locomotive, and fix the rate of motion at 38 miles in an hour, or 1,000,000 miles in three years, we do understand the rate of motion. Our journey is from our sun outward to the rims of the visible universe. By a former calculation in describing the solar system we found that at the above rate of speed, without stopping for a moment, we should pass beyond our outer boundary, the orbit of Neptune, in about 8,000 years, and now pursuing our journey we should reach our nearest solar neighbor in about 60,000,000 to 100,000,000 years, and at the end of about 1,080,000,000 years should reach the outer boundary of the visible universe. But as yet we have but contemplated the universe as given to the eye. Until within a recent period that would UniVerse of seem to have been the whole extent. That other and tbe telescope. incomparable heavens existed and would at some future time be revealed scarcely entered the dreams of men. But the diligent research which finally disclosed what those visible heavens Avere developed the fact that out beyond there were still greater wonders awaiting discovery. There were stray hints in unex plained phenomena. The eye had exhausted its power, but gen ius, unsatisfied, busied itself with invention. The lens, in part by a happy accident, was discovered. It was found to be able 72 Studies in Theology. to double them to thousandfold the eye which God *hM given. In addition to magnifying and making more plain and beautiful the visible heavens, and thus aiding in deciphering them, it was found to have another more important power, that of extend ing the vision, penetrating into new and more distant regions of space. The result Avas the discovery of a new universe so much more wonderful than the old that the old dwindled into in significance. To the six thousand suns it added millions. Out beyond the dim stars of the sixth magnitude which aforetiiiie were supposed to be the frontiers of the universe it brought to view phalanx upon phalanx, galaxy upon galaxy, rank behind rank whose light had required half a million years to pass the mighty interval. The Milky Way cast away its cloud robes and flamed into a score of million suns ; and yet on and on were piled unresolved nebulae of still more distant outposts of crea tion. STARS OF DIFFERENT MAGNITUDES. " Of the stars of the first magnitude, which include all the Number of brightest and supposably the nearest stars in the eighth magnt- heavens> there are about twenty. Of this number tude. Sirius is so incomparably the brightest as almost to constitute a class itself. The stars of the second class are those in which there is one distinct step dowmvard from the brilliancy of those of the first magnitude. The brighter stars in the con stellation of the Great Bear (the Dipper) may be taken as exam ples. In the entire heavens we have about sixty-five stars of the second magnitude. Immediately below the second magni tude Ave have the stars of the third magnitude to the number of 190. Next come' the stars of the fourth, 425 ; the fifth, 1,100 ; and so on down to the sixth, 3,200, which complete the stars visible to the naked eye. In stars of telescopic mag nitude we have the seventh, to the number of about 13,000, while the eighth has 40,000, and the ninth 142,000. Beyond the Solar System. 73 " It will thus be seen that the number of stars increases when we approach the lower magnitude, and when we come to those magnitudes below the ninth the number speedily reaches from thousands into millions. The minutest stars visible in powerful telescopes are usually stated to be of the fourteenth or fifteenth magnitude, while in the very greatest instruments magnitudes two or three steps lower can be observed, or to the eighteenth magnitude." * Thus it appears that as we penetrate the heavens from one magnitude or depth to another the wider disk or area Ratioof m- of vision increases the number of stars at the rate of creaseaswe penetrate the about threefold. Were that the exact as it is the heavens. proximate ratio, the number of stars discernible at the greatest depth yet reached by the most poAverful instrument would be the enormous sum of about one thousand seven hundred and twenty-one millions two hundred and twenty-one thousand two hundred (1,721,221,200). But actual count up to the stars of the ninth magnitude sIioavs the rate of increase to be much greater as we penetrate to the deeper depths. It is estimated that there are stars visible to the eye whose light has required one hundred and twenty years to reach us. A telescope which penetrates six thousand times that depth Avould still see a star of the first magnitude were it carried back to that distant point. It thus appears that we reach stars whose light has been tens, perhaps hundreds of thousands of years reaching our planet. Chalmers says : " What is seen may be as nothing to what is unseen ; for what is seen is limited by the range of our instru ments. What is unseen has no limits ; and though all which the eye of man can take in or his fancy can grasp were swept away, there might still remain as ample a field over which the Divinity may expatiate, and which he may have peo- * Stars of the ffeavens, by Ball, p. 390. 74 Studies in Theology. pled with innumerable worlds. If the whole visible creation were to disappear it would leave a solitude behind it, but to the infinite mind, that can take in the whole system of nature, this solitude might be nothing — a small unoccupied point in the immensity which surrounds it, and which he may have filled with the wonders of his omnipotence. Though this earth were to be burned up, though the trumpet of its dissolution were sounded, though yon sky were to pass aAvay as a scroll, and every visible glory which the finger of the Divine has inscribed on it were to be put out forever, an event so awful to us, and to every world in our vicinity, by which so many suns Avould be extinguished, and so many varied scenes of life and of population would rush into forgetfulness — what is it in the high scale of the Almighty's Workmanship ? A mere shred, which, though scattered into nothing, would leave the universe of God one entire scene of greatness and of majesty. Though this earth and these heavens were to disappear there are other worlds which roll afar ; the light of other suns shines upon them, and the sky which mantles them is garnished with other stars. . . . The universe at large would suffer as little in its splendor and variety by the destruction of our planet as the verdure and sublime magnitude of a forest would suffer by the fall of a single leaf." * Before we take our leave of the inorganic universe there are still other aspects in Avhich it must be studied. We have viewed it simply Avith respect to its magnitude and extent in space. Amazing as the results of investigation are on this single aspect of the subject, truth compels the confession that outer bound- we have not reached the utmost facts. The outer aryunex- - - ... . piored. boundary still remains unexplored. Any instru ments yet made leave unresolved nebulae on all the horizon. The vast realms beyond, for aught we know, immeasurably * Astronomical Discourses. Beyond the Solar System. 75 transcend all that has been brought under observation. But there is a limit ; somewhere in the illimitable expanse there is a boundary beyond which no world revolves, an outer space where no sun or star lights up the infinite void. The in organic universe is finite. Besearch has not come to the bor der, but there is such a border of creation. Postulate : Even the Infinite cannot create an infinite uni verse of matter. Whatever has figure or extension However must have a limit ; and as all collocations of ulti- be unite."3 mate atoms are reducible by compression into still smaller di mensions the largest dimensions are different from the smallest in size ; and all size is finite. Each atom has an identity of its OAvn, which, however compounded with others, it cannot lose. It might forever exist apart and in its own space, and would so exist uninfluencing and uninfluenced but for a force imparted to it or exerted in it which imparts to it influence on every other atom. The atom, in fact, is never found without influence or force of some kind. Within the realm of space in which mat ter exists there must be a medium for such influence. There is no absolute vacuum. When we suffer the idea of the universe to unfold itself in the mind the first thought, perhaps, is that of immense extent in space. But this conception is found to be incomplete. An other element in the great idea is found to be demanded. Thus we are led to think of the world in time. A great time is con ceived of as corresponding to great space ; still the mind is not satisfied. As we have the three dimensions in geometry, so there would seem to be demanded three aspects of the universe, each as the complement of the others, and all entering into the ideal perfection. Thus there comes in still another concep tion. It is that of degree, of rank, of a rising higher in the or der of being. The three dimensions are now complete and the mind is satisfied. We have breadth, we have length, we have 76 Studies in Theology. altitude. We have what we have called the time aspect of the universe. When the thought has taken full possession of the mind we cannot lose any part of it without feeling that the ideal harmony of the whole has been impaired. There is dis cord, deformity, and irrationality in the conception of immense worlds in space, having an almost infinitesimal brevity in time. It is the thought of vast breadth without length. There is the same discord, the same unsatisfying incompleteness, when Ave think of the universe as length and breadth without altitude. As we are not satisfied to regard our world in space as the only space occupied by rational personalities, so neither are Ave satis fied to regard our world in time, or our world-time (welt-2ei£) as the only world-time to the exclusion of all similar past or to come. And when we have come thug far, equally inharmoni ous is felt to be the supposition that our OAvn level is the high est altitude of the created universe, or that there are not above us orders and ranks of beings ascending to multiples bearing 6ome ratio, at least, to the descending grades, which we regard as existing below us. It is hard to think that the world ends with our space, that it began with our time, or that its upward growth is bounded by what we may ever so boastingly style our progress. In either of these directions the conceiving faculty stretches on to infinity or toward infinity ; and the man of science, in his claim for the human dignity, has no more right to limit it in one aspect than he has to change his theo logical view with an attempt to amend it in another. We do not say that this feeling is the measure of truth, or that there are these world-spaces, these world-times, and these world-alti tudes of being because the mind has a tendency thus to con ceive them ; yet still we regard it as worthy of consideration in our mental history as we trace its effects in modes of thinking. Now, to make an application of the general thought, we may say that the first, or space aspect, is the favorite field of mod- Beyond the Solar System. 77 em science, although she has lately entered upon the second. The third she has, as yet, almost wholly ignored. Scientific men have either said nothing about it or they have shown a tendency, at least, to make man the highest thing in creation next the Deity, and the present state of our world the measure of universal growth. On the other hand, this first or space aspect is far from being the prominent one in the Scriptures. The Bible tells us noth ing about suns and systems and other space worlds like the one in which our own habitation is assigned. Its expression, " the heavens and the earth," comprehends the universe. By the former is meant the visible round mundus which seems to roll overhead. And yet in those reduplications of the terms to which we have alluded, and in such expressions as we find in Psalm viii, 1, "thy glory above the heavens," there might seem to be an aiming at an idea beyond ; though whether this world came under the aspect of space or degree — that is, in alti tude of supposed upward extent, or of altitude in rank of being — cannot, perhaps, be certainly determined from such passages alone. In respect, however, to this space aspect of the worlds, and the silence of Scripture about it, there are two common falla cies on which we would briefly dwell. One is that such aspects come wholly from science— that is, modern science. To this it is said we are indebted for our enlarged view of the universe. Now, it requires no great amount of learning or thought to show the falsehood of such an assertion. The idea of the plu rality of worlds is full as much an a priori as an a posteriori judgment. It belongs to all thinking souls, whatever their amount of either positive or hypothetical science. Such a soul of its own promptings asks the question, Has not God made other worlds than this, and made them to be inhabited? We find unanswerable evidence of such thinking among the medi- 78 Studies in Theology. tative men of the olden time. The idea of the plurality and even the infinity of worlds can be shown to have been among the speculations of the earliest philosophy. It may have had, with some, more of a metaphysical than of a physical aspect ; and yet the thought, in its simplest and most obvious form, comes most naturally to the human mind. Infinite or vastly ex tended space we long to fill up in some way, if not with worlds like this, at least Avith exhibitions or exercises of divine poAver. Why should not God have thus filled it ? Why should he not thus have filled one part of space as well as another ? If crea tion is the manifestation of his glory is there not a demand for the thought that this manifestation must have been in spaces and times exceeding our own visible spaces and our OAvn com puted times by measures to which no human arithmetic can even make an approach? It may be thought, perhaps, that there is a dangerous tendency in such speculations or in the admission of such a law of thinking as either necessary or nat ural to the mind. It tends to pantheism, it might be said. It would seem to involve a necessity of creation. But to this there is a prompt and easy answer. Carry our thought to the furthest conceivable extent, and the universe' is still finite. We are compelled to admit a time when creation is not, and spaces where it is not. Carry the objection boldly out to the very con clusion it affects to draw, and such conclusion furnishes its OAvn perfect refutation. If God must create, he must create every where. There could be no vacuum anywhere. And so in respect to time and degree. The idea that the universe is finite in one aspect is no more difficult than the idea of its being finite in the other. The other fallacy to which we alluded as connected with the space aspect is found in the common opinion that not only the intellectual notion, but the devout feeling, of God's greatness is vastly enlarged by the discoveries of modern science, or what Beyond the Solar System. 79 may be called the mathematical or nnmerical idea of the uni verse. Now, in reference to this it may be said, in the first place, that our emotional conceptions are very little dependent upon our speculative or scientific knowledge, as expressed in numerical or quantitative formulas. The reason may follow these to any extent, but the power of conceiving cannot go beyond a certain limit. We have no higher, no greater con ception of a million worlds than of a thousand, no greater con ception of a thousand Avorlds than of a hundred ; yea, the image or conception Avhich one man has of one hundred worlds may be far inferior in grandeur, in vividness, in power of emotion, to that which another soul has of one. David and Socrates, with no knowledge of the numerical distances or magnitudes of the stars, may have really had a wider, a loftier, a more rever ent feeling of the greatness of God's kingdom than Laplace. So may Ave say one soul may have a more lofty as Avell as a more devout vieAV of God's greatness at the sight of a mountain than another in the contemplation of planets and comets and nebulae and double stars, Avith all their merely numerical or scientific estimations. The reason is that the latter has merely numbers and mathematical formulas. His soul is upon his cal culus instead of the heavens. It Avould be equally upon it em ployed to measure the most microscopic distances. We aston ish ourselves Avith long toavs of decimals, but no delusion could be greater than that which would make these immense numbers the measure of ideas, much less of the moral emotions connected with them. He Avho praised God for making " Orion and bringing forth Mazzaroth in his seasons " may really have had a more awe-inspiring view of the universe than the modern lecturer avIio talks to us of millions and billions and trillions and the wondrous human intellect that can make such tran scending calculations in arithmetic. Yet still the stars remain but points for the conception as well as for the eye. The 80 Studies in Theology. fancy, too, that peoples them is only a repetition of the world in which we dwell. It is only a numerical enlargement, and even this, instead of being habitually with the mind like the sense of grandeur which has always been connected with the visible firmament, is only fully present while the mathematical formulae are before it. The third, or rank, aspect, we have said, is peculiar to the Bible. Science has little or nothing to say about it. The Scriptures, both Old and New, give us no obscure intimations of ascending ranks of being — of angels, of archangels, thrones, dominions, principalities, powers, seraphim, kedoshim, or holy ones, rising higher and higher until the mind is lost in amazing altitude of conceived power and intelligence. See Lewis's Six Days of Creation, pp. 338-342". appalling depths of space. In a recent lecture Sir Robert Ball said that a telegraphic message would go seven times round the earth in a second, and if a telegraphic message could be sent to the moon it would reach its destination in a little more than a second. It would take something like eight minutes to arrive at the sun ; but how long, think you, would it take to get to Alpha Cen- tauri, traveling thither 180,000 miles a second? Seconds, minutes, hours, days, weeks, months, would not be long enough ; it would take no less than three years, traveling all the time at that tremendous pace, before it would reach its destination. If that is the case with respect to the nearest of the stars, what must be said of those which are farther off ? There are stars so remote that if the news of the victory of Wellington at Waterloo had been flashed to them in 1815, on that celestial telegraph system, it would not have reached them yet, even if the message had sped at the pace indicated, and had been trav eling all the time. There are stars so remote that if, when Beyond the Solar System. 81 William the Conqueror landed in England in 1066, the news of his conqnest had been dispatched to them, and if the signals flew over the wire at a pace which would carry them seven times round the earth in a single second of time, that news would not have reached them yet. Nay, more, if the glad tid ings of that first Christmas in Bethlehem, nineteen centuries ago, had thus been disseminated through the universe, there are yet stars of which astronomers could tell us, plunged into space in depths so appalling that even the eighteen hundred and ninety-four years which have elapsed since that event would not have been long enough for the news to reach them, though it traveled 180,000 miles in every second. We add, there are now knoAvn stars so remote that half a million years would not suffice to convey the message to them. We cannot better conclude this survey of the inorganic uni verse than in the eloquent words of our own most eminent as tronomer, distinguished alike for his learning, patriotisnij and piety, O. M. Mitchell. The excerpt is from his treatise on Planetary and Stellar Worlds — a book which deserves a place in every student's library. We know of no more elevating and soul-expanding discussion : " Having now succeeded in gaining a knoAvledge of the dis tance which separates our sun from its remote companions, we- are prepared to extend our explorations of the universe. The* question naturally arises, how are the stars distributed through out space? — are they indifferently scattered in all directions, or are they grouped together into magnificent systems ? A cur sory examination of the starry heavens Avith the naked eye shows us, that so far as the larger stars are concerned they do- not appear to have been distributed in the celestial sphere ac cording to any determinate law ; but on applying the telescope that luminous zone which, under the name of the Milky Way, girdles the whole heavens is found to be composed of minute; 7 * 82 Studies in Theology. stars, scattered like millions of diamond points on the deep blue ground of the sky. " Sir William Herschel conceived the idea that it might be pos sible to fathom this mighty ocean of stars, and to determine its metes and bounds ; to give to it figure, and to circumscribe its limits. It will not be difficult to explain, in a few words, the general outline of the plan adopted by this extraordinary man in the prosecution of this wonderful undertaking. In case we admit that the stars are of equal magnitudes, and at equal distances from each other, it would not be difficult to ascertain how far they extended in any given direction, the one behind the other. It is manifest that, in examining the heavens with a telescope of given power and aperture, we shall be able to count more stars in the field of vieAV in those regions Avhere they are soar- ranged as to reach farthest back into space ; and in case we knoAV their absolute distance from each other, the number counted in any field of view will determine with certainty the length of the visual ray reaching to the most remote star visible in that field. " Now, although the hypothesis that the stars are of equal mag nitude, and are uniformly distributed through space, may not be rigorously true, yet doubtless the mean distances are not far from this hypothesis ; and although our results may only be ap proximate, yet as such they are to be relied upon, and they become the more interesting as they carry us to the utmost limits of human investigation. Armed with his mighty tele scopes, Sir William Herschel commenced the stupendous task of sounding the heavens, with the purpose of ascertaining Avhether the stars composing the Milky Way were unfathoma ble, or were bounded and circumscribed by definite limits. " Sweeping a circle round the heavens which cut this grand stratum of star in a direction nearly perpendicular to its circum ference, he directed his great telescope to a certain number of points along this circle, and as he moved slowly onward Beyond the Solar System. 83 counted all the stars visible in each field of view. It was fair to conclude that, wherever most stars were to be seen, there was the stratum deepest. Having gone entirely around the heavens, along the circumference of his circle, he had sounded the depth of the stars along a section of the Milky Way, and to obtain the figure of the section thus cut out was not a difficult matter. " He assumed a central point on paper to represent his point of observation. He then drew from this point lines radiating, and in the actual directions which he had given to his telescope while engaged in his explorations. On each of these indefinite lines he laid off a distance proportioned to the number of stars counted in the field of view in the direction which the line represented, and by joining these points thus determined he formed a figure which represented the relative depths to which he had penetrated into space ; and in case he could be certain that he had gone absolutely through the stratum in every instance and had grasped every star, even where the extent was mo^t profound, the figure thus constructed would represent the form of the line cut from the outside boundary of the Milky Way by the plane of the circle in which the explorations had been made. " Did he then actually penetrate the deepest portions, or any portion, of the Milky Way ? This was now his grand question, and to its decision he gave all his power and ingenuity. As a unit Avherewith to measure the space-penetrating power of his telescopes, he assumed the power of the human eye, and know ing that stars of the sixth magnitude are within the reach of the unaided eye, he concluded, from the law regulating the de crease of light, that these minute stars were twelve times more distant than the nearest or brightest stars. Now, a telescope having an aperture such as to concentrate twice as much light as the eye would penetrate into space twice as far, or would reach stars of the twenty-fourth order of distances, and so on 84 Studies in Theology. for telescopes of all sizes. In this way he concluded that his great forty-foot reflector, with a diameter of four feet, would penetrate 194 times as far as the naked eye, or that it would still see a star of the first magnitude if it were carried back ward into space 2,328 times its present distance ! " Such, then, was the computed length of the sounding line employed in gauging these mighty depths. Suppose, then, it was required to determine whether this line actually penetrated any given region of the Milky Way. Even with a single tele scope, a series of experiments may be performed which go very far to determine this great question. As the space-penetrat ing power of a telescope depends on the diameter of its aper ture, it is easy to give to the same instrument different powers, by covering up, by circular coverings, certain portions of its object glass. Take circles of pasteboard, or any other suita ble material, and in the first cut an opening one inch in diam eter, in the second an opening of two inches, and so on, up to the diameter of the object glass. These diaphragms, being successively applied to the object glass, give to the telescope space-penetrating powers proportioned to the diameter of the opening. " In this way Herschel prepared himself to explore one of the deepest portions of the Milky Way. The spot selected was a nebulous or hazy cloud in the sword handle of Perseus, in which, to the naked eye, not a solitary star was visible. With the lowest telescopic aid many stars are rendered visible, surrounded by a hazy light, in which minute glimpse points are occasionally to be seen. As the space-penetrating power was increased, the bright spots of light were successively resolved into groups of brilliant stars, and more nebulous haze came up from the deep distance, indicating that the visual ray was not long enough to fathom the mighty distance. At last the full power of his grand instrument was brought to bear, when a count- Beyond the Solar System. 85 less multitude of magnificent orbs burst on the sight, like so many sparkling diamonds on the deep blue of the heavens. There was no haze behind ; the telescopic ray had shot entirely through the mighty distance, and the clear deep heavens formed the background of the brilliant picture. " Thus did Herschel penetrate to the limits of the Milky Way, and send his almost illimitable sounding line far beyond, into the vast abyss of space, boundless and unfathomable. And now do you inquire the depth of this stupendous stratum of stars ? The answer may be given, since we have the unit of measure in the distance of stars of the first magnitude. Light, with its amazing velocity, requires ten years to come to us from the nearest fixed Stars, and yet Sir William Herschel concluded, from the examinations he had been able to make, that in some places the depth of the Milky Way was such that no less than five hundred stars were ranged one behind the other in a line, each separated from the other by a distance equal to that which di vides our sun from the nearest fixed star. So that for light to sweep across the diameter of this vast congeries of stars would require a period of five thousand years at the rate of twelve million of miles in every minute of time ! " The countless millions of stars composing the Milky Way ap pear to be arranged in the form of a flat zone or ring, or rather stratum, of irregular shape, which I shall explain more fully hereafter. Its extent is so great as properly to form a universe of itself. If it were possible, to-night, to wing our flight to any one of the bright stars which blaze around us, sweeping away from our own system, until planet after planet fades in the dis tance, and finally the sun itself shrinks into a mere star, alight ing on a strange world that circles round a new and magnificent sun, which has grown and expanded in our sight, until it blazes with a magnificence equal to that of our own — here let us pause and look out upon the starry heavens which now surround us. 86 Studies in Theology. "We have passed over sixty millions of millions of miles. We have reached a new system of worlds revolving about another sun, and from this remote point we have a right to expect anew heavens, as well as a new earth on which we stand. But no. Lift up your eyes, and lo ! the old familiar constellations are all there. Yonder blazes Orion, with its rich and gorgeous belt ; there comes Arcturus, and yonder the Northern Bear circles his ceaseless journey round the pole. All is unchanged, and the mighty distance over which we have passed is but the thousandth part of the entire diameter of this grand cluster of suns and systems ; and although we have swept from our sun to the nearest fixed star, and have traveled a distance which light itself cannot traverse in less than ten years, yet the change wrought by this mighty journey in the appearance of the heavens is no greater than would be produced in the relative positions of the person filling an ordinary church near its cen ter who should change his seat Avith his immediate neighbor ! " Such, then, is the scale on Avhich the starry heavens are built. If, in examining the magnificent orbits of the remoter planets, and in tracing the interminable career of some of the far-sweep ing comets, we feared there might not be room for the accomplish ment of their vast orbits, our fears are now at an end. There is no jostling here ; there is no interference, no perturbation of the planets of one system by the suns of another. Each is iso lated and independent, filling the region of space assigned, and within its own limits holding on its appointed movements. " Thus far we have spoken only of the Milky Way. In case it be possible to pierce its boundaries and pass through into the regions of space which lie beyond, the inquiry arises, What meets the vision there? What lies beyond these mighty limits ? Does creation cease with this one great cluster, and is all blank beyond its boundary ? " Here again the telescope has given us an answer. When we Beyond the Solar System. 87 shall have traveled outward from our own sun, and passed in a straight line from star to star, until we shall have left behind us in grand perspective a series of five hundred suns, we then stand on the confines of our own great cluster of stars. All behind blazes with the light of countless orbs, scattered in wild magnificence, Avhile all before us is deep, impenetrable, un broken darkness. No glance of human vision can pierce the dark profound. "But summoning the telescope to our aid, let us pursue our mighty journey through space ; far in the distance we are just able to discover a faint haze of light — a minute luminous cloud which comes up to meet us — and tOAvard this object we will urge our flight. We leave the shining millions of our own great cluster far behind. Its stars are shrinking and fading ; its dimensions are contracting. It once filled the whole heavens, and now its myriads of blazing orbs could almost be grasped with a single hand. But now look forward. A new universe of astonishing grandeur bursts on the sight. The cloud of light has swelled and expanded, and its millions of suns now fill the whole heavens. "We have reached the clustering of ten millions of stars. Look to the right, there is no limit ; look to the left, there is no end. Above, beloAv, sun rises upon sun, and system on sys tem, in endless and immeasurable perspective. Here is a neAV universe as magnificent, as glorious as our own — a new Milky Way, whose vast diameter the flashing light Avould not cross in thousands of years. Nor is this a solitary object. Go out on a clear, cold winter night, and reckon the stars which strew the heavens, and count their number, and for every single orb thus visible to the naked eye the telescope reveals a universe, far sunk in the depths of space, and scattered with vast profusion over the entire surface of the heavens. " Some of these blaze with countless stars, while others, occu- 88 Studies in Theology. pying the confines of visible space, but dimly stain the blue of the sky, just perceptible with the most powerful means that man can summon to the aid of his vision. These objects are called clusters and nebulae— clusters when near enough to per mit their individual stars to be shown by the telescope, nebulae when the mingled light of all their suns and systems can only be seen as a hazy cloud. " Thus have we risen in the orders of creation. We com menced with a planet and its satellite ; we rose to the sun and its revolving planets, a magnificent system of orbs, all united in one great family and governed by the same great law ; and we now find millions of these suns clustered and associated together in the formation of distinct, universes, whose number, already revealed to the eye of man, is not to be counted by scores or hundreds, but has risen to thousands, while every increase of telescopic power is adding by hundreds to their catalogue. " Let us now explain these ' island universes,' as the Germans have aptly termed them, and attempt approximately to circum scribe their limits and measure their distances from us and from each other. Sir William Herschel, to Avhom we are indebted for this department of astronomy, conceived a plan by which it Avas possible approximately to sound the depths of space and determine, within certain limits, the distance and magnitudes of the clusters and nebulae within the reach of his telescopes. To convey some idea of his method of conducting these most wonderful researches, imagine a level plane, of indefinite ex tent, and along a straight line, separated by intervals of one mile each, let posts be placed bearing boards on which certain words are printed in letters of the same size. The words printed on the nearest board we will suppose can just be read with the naked eye. To read those on the second, telescopic aid is required, and that poAver which suffices to enable the letters to be distinctly seen is exactly double that of the unaided eye. Beyond the Solar System. 89 The telescope revealing the letters at the distance of three miles is threefold more powerful than the eye, and so of all the others. In this way we can provide ourselves with instru ments Avhose space-penetrating power, compared with that of the eye, can be readily obtained. " Now to apply these principles to the sounding of the heavens. The eye, Avithout assistance, would follow and still perceive the bright star Sirius, if removed back to twelve times its present distance. After this, as it recedes, it must be followed by the telescope. Suppose, then, a nebula is discovered Avith a tele scope of low poAver, and it is required to determine its charac ter and distance. The astronomer applies one power after an other, until he finally employs a telescope of sufficient reach to reveal the separate stars of which the object is composed, which shows it to be a cluster; and since the space-penetrating power of this instrument is known, relative to that of the human eye, in case the poAver is one hundred times greater than that of the eye, then Avould the cluster be located in space one hundred times farther than the eye can reach, or twelve hundred times more remote than Sirius, or at such a distance that its light would only reach our earth after a journey of one hundred and twenty thousand years ! "Such Avas Herschel's method of locating these objects in space. Some are so remote as to be far beyond the reach of the most powerful instruments, and no telescopic aid can show them other than nebulous clouds of greater or less extent. It was while pursuing these grand investigations that Herschel was led to the conclusion, that among the nebulae which were visible in the heavens there were some composed of chaotic matter, a hazy, luminous fluid, like that occasionally thrown out from comets on their approach to the sun. " Among these chaotic masses he discovered some in which the evidences of condensation appeared manifest, while in others 90 Studies in Theology. he found a circular disk of light with a bright nucleus in the center. Proceeding yet farther, he found well-formed stars surrounded by a misty halo, which presented all the character istics of what he now conceived to be nebulous fluid. Some of the unformed nebulae were of enormous extent, and among those partially condensed, such as the nebulae with planetary disks, many were found so vast that their magnitude would fill the space occupied by the sun and all its planets, forming a sphere with a diameter of more than six thousand millions of miles. Uniting these and many other facts, the great astronomer was finally brought to believe that worlds and systems of Avorlds might yet be in the process of formation by the gradual conden sation of this nebulous fluid, and that from this chaotic matter originally came the sun and all the fixed stars which crowd the heavens. This theory, extended, but not modified, in the hands of Laplace, is made to account for nearly all the phenomena of the solar system. " For a long time this bold and sublime speculation was looked upon, even by the wisest philosophers, with remarkable favor. The resolution of one or two nebulae (so classed by Herschel), with the fifty-two feet reflector of Lord Bosse, has induced some persons to abandon the theory and to attempt to prove its utter impossibility. All that I have to say is that Herschel only adopted the theory after he had resolved many hundreds of nebulae into stars ; and if there ever existed a reason for accepting the truth of this remarkable speculation, that reason has been scarcely in any degree affected by recent discoveries. " I have examined a large number of these mysterious objects floating on the deep ocean of space like the faintest filmy clouds of light. No power, however great, of the telescope can ac complish the slightest change in their appearance. So distant that their light employs (in case they be clusters) hundreds of Beyond the Solar System. 91 thousands of years in reaching the eye that gazes upon them, and so extensive, even when viewed from such a distance, as to fill the entire field of view of the telescope many times. Sirius, the brightest and probably the largest of all the fixed stars, with a diameter of more than a million of miles, and a distance of only a single unit compared with the tens of thousands which divide us from some of the nebulae ; and yet this vast globe, at this comparatively short distance, is an inappreciable point in the field of the telescope. What, then, must be the dimensions of those objects which at so vast a distance fill the entire field of view even many times repeated ? "Herschel computes that the power of his great reflector would follow one of the large clusters if it were plunged so deep in space that its light would require three hundred and fifty thousand years to reach us, and the great telescope of Lord Rosse would pursue the same object probably to ten times this enormous distance." 92 Studies in Theology. TIME MEASURES OF THE UNIVERSE. The mind does not rest with the discovery of these vast masses and their vaster distances from each other in space, and their interrelations of motion and harmony, amazing as these discoveries are. One set of facts discovers another. Pushing its inquiries still further, it discovers, not simply that they are composed of similar substances, and what these sub stances are, but, deeper yet, what their primordial condition has been, and by what process they have been brought into their present condition. In conducting the inquiry it returns to the study of the objects immediately about it, the study of the earth itself. It has given the name matter to the substances of these marvelous masses it has been contemplating ; it now returns upon its track to find out what this matter is and the variety it manifests. Here we begin our study, and that we may not fall into aber rations of fancy we will call to our aid the definitions supplied by the ablest scientists, and the conclusions now universally ad mitted to be true and reliable. Matter is a substance which has form and Avhich occupies space and which is impenetrable, that is, which precludes any other substance from occupying the same space which it does. In its final forms it is an atom. The earth is a body which consists of innumerable atoms. All masses or worlds are simply accumulations of atoms, held in fixed relation to each other, so as to constitute a unit in space marked off by distance from other similar masses, and so as to have an economy of its own. Time Measures of the Universe. 93 From these accredited facts of science we postulate as the primary stage and most primitive form of matter the ether which is found pervasive of the entire universe, The ether' a simple and uncompoundable substance, which, as an ocean whose boundaries extend to the inclusion of all other material substances, touches and relates every other atom of every other substance, connecting the interstellar spaces and all spaces of the universe together. This most primitive form of matter is also the most attenu ate ; the atmosphere is gross compared with it. It bathes the sides of all atoms in the densest solids and interpenetrates the atoms of impalpable gases themselves. It is the universal frame in Avhich all atoms are set, parting every one from every other, and binding all together. All Avorlds revolve in it; it is the highway for light and the electric fluid, and for gravitation itself ; the invisible and imponderable forces travel it as they bind the spheres together and exert their power upon them. If there is such a substance as ether it has no resemblance to any other of the sixty-two substances of matter except occupancy of space and figures as a whole. It is not ponderable ; it is not compoundable with other substances ; it is not drawn toward a center by gravitation ; it exerts no influence ; it has no affinities ; and yet it may furnish the condition of the existence of every other substance and of the forces exerted by them or in them. The primordial condition of all other grosser matter was that of atomic severance, each atom existing apart by itself in its own place, neither compounded with nor affected by its neigh bor, any more than if it were alone the universe. An atom, though reduced to infinitesimal dimensions, so as neither to be palpable nor visible, is a reality — has the quality of individual being in it ; and if there be collocations and com- 94 Studies in Theology. pounding of atoms into masses they must first exist as distinct and separate entities. The one involves the other. Atoms are antecedent to masses, and masses are resolvable into atoms. All atoms, that is, all matter in whatever state, are character ized by a certain number of common properties, The atom. which, being universal, are essential. No atom does or can exist without them ; no atom can be deprived of them. Where they are not found matter does not exist. These uni versal properties are extension, figure, impenetrability, inde structibility, inertia, where atoms become massed ; divisibility, paucity, compressibility, expansibility, mobility, and gravita tion are also discovered to have been potential properties of all atoms. In mass matter assumes one of three possible forms : solid, liquid, or aeriform ; solid when the atoms cohere so that they cannot move among themselves ; liquid when its particles do not cohere, but move freely among themselves, as water ; aeri form when it exists as atmosphere, or gases, or vapors. There are known to be sixty-two differentiable kinds of atomic substances possessed of these common properties. Of these fifty are distinguished by a peculiar luster and are called metals. The others are distinguished as nonmetallic. The non- metallic elements are oxygen, hydrogen, nitrogen, chlorine, iodine, bromine, fluorine, selenium, sulphur, phosphorus, car bon, and boron. These original substances are called simple, for the reason that they cannot be resolved into more than one element, though they may be compounded with some of the others. Matter as we know it is rarely found in the simple form ; the atmosphere is compounded of twenty-one parts of oxygen and Time Measures of the Universe. 95 seventy-nine parts of nitrogen. Water is also a compound sub stance, having one part of oxygen to eight parts of hydrogen. These sixty-two differentiable substances are not all equally distributed over the surfaces of the earth or in the masses of matter in world forms. Many of them are extremely rare, and discoverable only by most careful and delicate processes of investigation. Of the Avhole number ten or fifteen only are found in the great bulk of the objects or collocations with Avhich we are familiar. We have already stated that the atmosphere is compounded of but two of them, and also that the same is true of water. The great masses of rocks and earth are mainly composed of eight, and easily reducible to them, namely, oxygen, which is the principal constituent of universal matter, silicon, aluminum, calcium, potassium, sodium, chlorine, and iron. These original or simple substances, which in the ultimate form are all alike atomic — that is, exist as atoms — are found to be undergoing incessant changes — changes of place and relations ; changes of composition and decomposition ; changes ChanKes of of condition from hardness, or solids, to fluids, and atoms' from fluids to gases, and back again ; changes of temperature from hot to cold, and the reverse ; changes of motion and mass, of texture and form, of taste and odor and color. The changes are traceable to causes to which we give the name of forces — we call them natural forces, and mean thereby that they somehow belong to the nature of these substances, and must therefore under given conditions occur. When the conditions are found under which they are sure to exist we call them laws. Forces are not substances. They have none of the properties of substances, as length, breadth, and thickness, or form or divisibility. They do not occupy space. They act in and on matter, but are not matter or essential to the existence of 96 Studies in Theology. matter, though always appearing in matter. Ultimately all forces are a mode of agency. Forces are differentiable modes of action. It is possible to conceive of matter— that is, atoms- existing without affinities or motion of any kind ; but it does not so exist. If atoms existed without the forces it would be simply as an infinite expanse, a useless immensity of mere stuff. It would exist to no end. The forces are few and simple : they are attraction of gravi tation and molecular forces. The name gravitation is applied to that force by which all the bodies or atoms of the universe attract or tend to approach each other. It differs from all molecular forces in that it is universal and constant under all conditions ; acting at all times, upon all substances, and at all distances. It is that master force which binds all atoms together and regulates the motions of worlds, from which there is no escape — that force by which all atoms are drawn toward some center. It acts instantaneously. It treats all matter alike. Its only variation is that it increases with the increase of the mass, and diminishes as the square of the distance increases. Formulated it reads : a force which acts in proportion to the mass, and which becomes less as the square of the distance. Molecular forces differ from gravitation in that they act in ternally upon particles of matter when the particles are in close proximity, and only under such conditions. They are modes of interaction among contiguous atoms. The forces developed through the agency of heat (which is a state of some material body) and light, electricity and magnetism, are diverse in their nature and affect different forms of matter differently. They differ from gravitation inasmuch as their influence is not universal and constant, but local and limited both in time and space. They differ also from molecular Time Measures of the Universe. 97 forces inasmuch as their influence is exerted at measurable distances, though not at great distances. Molecular forces are found under four manifestations or varieties : cohesion, adhesion, capillary attraction, and affinity. Cohesion is that form Avhich binds together atoms of the same kind to form a compact or uniform mass, and differs from gravitation, which draws all kinds into a common mass ; the force which holds together atoms of iron, stone, or other co herent masses. By cohesion the constituent atoms are not de stroyed, but united, cemented. Adhesion is another form of molecular force which causes unlike substances to adhere, but not unite, as smooth surfaces cleave together. Capillary attraction is a form of molecular force. It mani fests itself variously between the surfaces of solids and liquids. Affinity is a mode of molecular force precisely the reverse of cohesion, and next to that most efficient to the conversion of atoms into masses. As cohesion binds together atoms of the same kind into solid masses, so affinity binds together and unites into solid masses unlike substances. The resultant is not mere mass, but a compound which manifests different qualities from any discoverable in either part separately. The compound is thus seen not to be a mere mixture of different parts, but a> transfusion or interblending, making a third something not in bulk merely, but in a different class of properties. Water is not oxygen, nor yet hydrogen, nor a mixture ; but a substance Avith new properties belonging to neither. Thus it appears that the action of gravity and the several molecular modes of force differ in their manifestation and results. The force of affinity binds together the atoms of the elements oxygen and hydrogen to constitute a molecule of water. Cohesion unites the molecules thus formed into a drop or an ocean. Adhesion causes the union of water with the surfaces; of different substances. Capil- 98 Studies in Theology. lary attraction causes water to rise above its level ; while the force of gravity causes coherent quantities of water to descend in rain from the clouds, or to move down inclined planes as rivers until they find their level. Having now possessed ourselves of the knoAvledge of the vast masses of inorganic substance aggregated in worlds, and of their distribution through immeasurable regions of space ; and having discovered that these masses are composed of innumera ble atoms of such infinitesimal dimensions as to require the aid of the microscope to render them visible ; and having found that these atoms are of sixty-two kinds of differentiable substances variously impacted and compounded ; and having ascertained the forces which act in and upon them to produce the various changes through which they have passed and are passing to bring them to their present conditions and relations, Ave are prepared to consider another aspect of the inorganic universe, namely, its temporal measures, or the method by which it has been brought to its present state and the length of time con sumed in bringing it to its present condition. By the essential properties of the atom we were enabled to determine with the utmost certainty that, illimitable as it is, space occupied by matter is nevertheless finite, boundable, and Theuniverseactuallv bounded> though its utmost bounds are not bounded. ascertained or ascertainable by any poAvers within our possession or reach. No certainty of knowledge is greater or more secure than this, that out beyond whatever is figur- able or has figure as its essential property there is an unfig- urable immensity or infinitude of space where matter might exist. There is a center and circumference of all matter sub stance, and its diameter, though unmeasured, is measurable. This we postulate as a necessary truth, reached not by observa tion but by intuition. Time Measures of the Universe. 99 The question Avhether it is also finite or limited in its time measures is that which we now raise. It is confessedly the most difficult problem in the whole range of scientific investi gation, and also the most important in its theological bear ings. As a scientific question it must be treated in the light of known facts, and must be subjected to the tests which deter mine facts to be facts. A class of thinkers arrogating to them selves the appellation of scientists assert that all original inor ganic substances are eternal, and that all subsequent changes are products of their inhering forces. Another class as positively affirm that all such substances had a beginning and were created, and that all subsequent changes are outcomes of the agency which produced them. The first position leads to atheism ; the second affirms theism. What are the known facts in the light of which these antago nistic affirmations are to be tested ? It were an easy Light. thing to appeal to the Bible and say that it settles it, and so to refuse further inquiry. But this summary method, however it might satisfy some minds, fails to give content to others, who imagine that facts contradict it. Facts must be the court of last appeal, since no assumption can stand against them. The first fact to which we need to attend is this : that we have no knowledge of the actual origin of any atom BeglimiI1g of matter. This is a universally admitted fact. Of of matter- the beginning of matter as a whole, or of any part of it, we know nothing, either by observation or induction or intuition. The second fact we call attention to is this : whether inorganic substances had a beginning or not, we know as a fact that it does exist, and has existed through immeasurable ages of time, and we are able to trace the history of changes in it throughout these vast eons to what seems to be its most primitive — actually 100 Studies in Theology. primordial — condition. This we affirm to be a fact, and one of great importance in its bearing on the question under considera tion, and now ask attention to its proofs. The first proof we submit is drawn from the observation of the heavenly bodies. It is established by indubitable evidence deduced by many actual experiments of the most unquestionable accuracy that light is subject to the law of motion, if it is not in fact a mode of motion, and hence that it occupies appreciable time in its passage through space. If any fact is absolutely determined, this is. The existence of the sun is not more certain than that it requires about eight minutes for its light to pass over the space which separates it from the earth. The movement is determined at about one hundred an d ninety thousand Time meas- rf ures of light. mjles in a second of time. This is not the place to re cite the evidence which supports this fact ; nor is it necessary. The eye discerns stars whose distance has been measured Avith mathematical accuracy, whose light requires a hundred and twenty years to cross the space separating them from the observer who beholds them. The telescope, with a penetrating power many thousand times that of the eye, reveals stars whose light has required two hundred and fifty thousand years to reach the eye of the observer, and unresolved nebula out beyond whose light has required double that time to make the transit. No one who is in formed will doubt these facts. They fall far within the limit of reality. The ablest and most devout astronomers have affirmed that the inorganic universe, under actual observation by means of instruments, is of such extent that its diameter would require millions of years for light to traverse. The processes by which these conclusions are reached are open and within the reach of all studious observers. The fact thus established by careful scientific method deter mines that the universe as existing with developed solar bodies has been as it now is for not less than a million years. How Time Measures of the Universe. 101 much longer we do not conjecture, nor does astronomic science give any clew. Nor does the fact here adduced simply prove the measureless antiquity of those distant stars, or, more properly, suns. The evi dence is that our own sun, whose light comes to us in eight min utes, has been sending forth its beams to these far-off worlds dur ing the same period — is, in fact, of the same antiquity with the most ancient of its compeers. It matters nothing what the theory of light is — the result is the same. This appears from two facts : first, the harmony of the spheres and their fixed relations, and the great universal law of gravitation which determines their rela tions. Second, from the fact that its existence is Harmonyof traceable in its effects on our planet, both as to its the spheres. inorganic changes and its organic phenomena, to a period much more remote than that required for the transit of light across the longest diameter of the known stellar universe. Nothing is more certain than that it was needed to be in its place con temporaneously with the existence of our planet itself, and that its solar function was needed in the earliest ages of organic existence. Our next proof is deduced from the science of geology. This science treats of the earth. It is relatively recent, but it has rapidly grown into one of the best understood branches, and now takes rank almost as one of the exact sciences. Its facts lie so within easy reach that they fall under immedi- Ages 0l ate observation, and -cannot be disputed. It deals geology. with forces and agencies, and the effects which they produce, which are now in full play under our direct cognizance. Its facts are numerous and open, and the knowledge of them is in creasing with every sun rising and setting. We now call atten tion to some of those well-known facts which point to the immense antiquity of the earth as an inorganic mass, or prior to the ages of fife. 102 Studies in Theology. Had the earth from the beginning been as we now find it, and remained a perfectly unchanged body, it is difficult to see how it would have been possible to get at any clew to its age ; indeed, it would have been impossible. The immutable gives no note of time. Changes denote time and forces which produce them. When the forces are known, and the conditions under which they act, and the relative time consumed in the effects, we are able to arrive at a proximate estimate of the whole period during which all the observed effects were wrought. To ascertain the changes through which the earth has passed we have to begin our researches with those which we observe and the causes which produce them. These changes are those which take place immediately upon its surface, extending to but a few inches beneath. Below that by actual observation Ave know absolutely nothing. But while we do not see below the surface so as to note what is passing there, we shall be able to show by many indubitable evidences that changes have been passing there through immeasurable ages of time. We shall find the same forces Avhich are now working changes under our eyes were working long ago just as now, when portions of the earth which are now miles deep below the surface were the then surfaces of the world. The agencies now working changes upon the surface may be named: gravitation, cohesive attraction, chemical affinity, changes of temperature, the heat of summer and cold of winter, erosion of rocks by chemical and mechanical agents, action of the atmosphere, organic growth and decay, rains, snows, cur- Agencies of rents of rivers and streams, the beating of ocean tides changes. and waveg on their shoregj c]0U(jbursts and inunda tions, earthquakes and volcanoes, uplifts and depressions of con tinents, windstorms, mechanical attrition, glacial slides and movements, geysers, springs, organic agencies, solar influences of light and heat. These forces are now at work uninter- Time Measures of the Universe. 103 mittently about us on every hand, often unnoted and always unappreciated, except by the few who carefully study their operations. The crust of the earth reveals evidences that the same forces have been busy along all the ages of earth's history, in more active and terrific forms as we descend to the period of their earlier and earliest manifestations. Most conspicuous among them is gravitation, chemical affinity, cohesive attraction, fire, and water. There have been periods extending through ages in which they Avere intensely active, producing the mightiest changes, ruptures of the earth's surfaces, cataclysms, and upheavals, evi dences of Avhich, as Ave shall see, remain to this day. Their operations are now quiet and orderly, and their effects only observable in local and transient changes. From year to year and generation to generation, and indeed throughout his toric time, there has been scarcely any marked change in the visible condition of the earth. The mountains and oceans and rivers and continents and islands are essentially the same as when man first made observation of it. The climatic changes are small ; the contour of land and water, the vegetable and animal tribes, the mountain ranges and river courses, the for ests and lakes, are the same our most ancient ancestors looked upon. The same birds sing in our groves, and the same fishes SAvim in our seas, and the same animals roam in our forests. It is the same earth our ancestors back to our primogenitor inhabited in all essential respects, modified only by the touch of man. The same stars shine above us in their exact places that guided and cheered the shepherds of Chaldea as they herded their flocks on the same slopes and in the same vales where their descendants live and toil to-day. Kingdoms have risen and passed away, civilizations have come and gone like shadows over the rocks, man's works and monuments have per ished, but the earth remains in its old orbit and turns its surfaces 104 Studies in Theology. to the sun unchanged through these human ages ; and yet great changes have been going forward even during this period, some of which will be noted. Changes are the records which the earth makes of its history. They tell the story of its age and of its experiences. The rec ord is often blurred and parts totally effaced, but enough is preserved to enable us to trace the story from its beginning to the present, and read backward and forward the romance of its youth and middle age all through from infancy to majority without the loss of a single chapter. " It is lead in the rock forever ; " more marvelous than the wildest dream of fancy, yet as real as the rocks in which they arc traced and as deter minable in the agencies which produce them and in their chrono logical order as the pages of a written history. As to read a book one must master the alphabet, so to read this ancient volume one must acquaint himself with the facts. Having observed the forces working about him and looking full upon the varied surfaces of the world all abroad, he begins to inquire the relations of the one to the other. Here is a vast region broken up into mountains ; adjacent is half a continent of rolling lands and stretches of plain ; here are great gorges and ancient beds of living or extinct rivers ; here are conical shafts thousands of feet high with dead craters in their sum mits and clay and lava accumulations along their sides and out into the plain about their bases leagues in extent ; over half a continent are scattered great bowlders and immense rocks weigh ing thousands of tons, separated from their congeners or native habitat. Everywhere over all the world are beds of gravel and rounded pebbles and bowlders piled up into hills hundreds of feet high ; along the sides of the mountains are striated rocks laminated in regular layers piled one upon the other ; along the ocean and lake and river shores are beaches, one, two, three, Time Measures of the Universe. 105 of accumulated rocks and soil, pointing unmistakably to ancient sea levels; there seem in some places, hundreds of miles in extent, substructures of walls laid as if in masonry ; the mate rials of which the walls are built are filled with casts of organ- isms which resemble creatures which now live ; here are vast measures of combustible rocks, many feet in thickness, and lower down, separated by other rocky strata, another and then still another and then still another ; doAvn beneath all is a vast crystalline base upon which the mighty accumulations are piled. The outcome of research is this, that these facts discover changes which have been passing in this outer crust of the earth through infinite ages, by the operation of the forces which are still, but more quietly, carrying on their processes to-day ; forces building and destroying the continents. Let us see if the history can be deciphered and the time, orders, and measures be determined. How were the mountains piled ? By the agency of internal fires. Hoav were the plains formed? By sedimentation in ancient seas and lakes and the attrition of the elements level ing elevations and filling up depressions, and by the deporta tion of comminuted substances by wind and water. How were the pebbles and rounded bowlders fastened ? By being rolled in currents and waves. How Avere the stratified rocks piled ? By deposits in ancient seas, lakes, and oceans deported from the dry land. How were the bowlders deported from their ancient homes and sown broadcast over the continents? By emptyings of frozen oceans over the continents. How Avere the coal measures corded under the rocky strata which hide them away ? By uplift of continents which grew the prolific vegetation of Avhich they are composed, and then by depression under shallow seas and ocean waters until superincumbent rock strata Avere laid down upon them, and so by repetition 106 Studies in Theology. until the series was complete. There is now no question among those who have patiently studied these phenomena about the correctness of these findings. That the mountains Avere reared by the agency of heat has, I believe, never been questioned. They are either volcanic in their origin and simple accumulations of substance spouted from internal depths, or ruptured masses, lifted and piled in jagged ridges and peaks by continental upheaval. Both agen cies are perfectly apparent and differentiable. If we add to these the agency of water floods poured from the clouds, and through the ages dashing down their sides in torrents and rivers, cutting deep gorges therein, Ave have a full account of their origin and outline. That the stratified rocks were made by sedimentation is proved by their structure and fossil contents, and by the visible operation of the same cause now. That the great bowlders were floated to their places by rushings of emptying oceans and by masses of icefloes is evident from the fact that striae and moraines show that they were dragged or driven along lines of movements. That pebbles were factured by being rolled in currents and waves of water is proved by the fact that the process is going on to-day in all river and lake and sea beds and shores, and from the fact that no other method of their formation can be assigned, and from the further fact that their snrfaces show that they were ground from other shapes into their rounded form. The force which formed the mountains is less capable of being measured, and less calculable as to the time required for the effect, but there are not wanting means of proximate calcu lations. Volcanic agency, though rapid Avhen in highest activity, requires time for its effects. Upbursts may be instantaneous, but Avhen we consider the vast ranges of mountains on all the Time Measures of the Universe. 107 continents, and beneath the oceans as well, apparently breaking up the entire crust of the globe, we are compelled to locate the agency causing such effect long anterior to the age of life on the planet, and during the formative period, antecedent to the secondary, or sedimentary crust, or to any subsequent upheavals, breaking the strata piled upon them, and in no way active in the formation of the secondary rocks. The force which has been operative in the production of the secondary rocks, or rocks made by sedimentation, is secondary almost, if not entirely, aqueous. The mode of its roeks- operation is gradual, and, though at times violent, usually rela tively quiet. It acts in the form of solution, or decomposition, and deportation. The loose or decomposed elements are taken up by it and deported and deposited in thin and proximately equal horizontal layers along the courses of rivers and their over flowed banks, and out in basins, lakes, and seas, into which the rivers empty, or in which they are held in solution from the bottom of the ocean. Before there were continents of dry land, but after water had formed, sedimentation may have commenced building at ocean bottoms. When portions of the crust were lifted above the watery enswathement a decomposing agency immediately began to grow upon the solid crust, just as at pres ent. Chemical and atmospheric action began to weather the crystalline mass and loosen its particles, and the descending rains forming into rills and rivers caught up the portable parts and carried them in solution, dropping them in the flow, but carrying their more portable or finer parts out into the basins where the water emptied itself, and dropping them over its floor. Thus the stratified rocks were made ; they are being so made now. The general cause of mountains (as indeed of all igneous phe nomena) is the reaction of the earth's hot interior Mountain upon its cooler crust. Mountain chains seem to changes. be produced by the secular cooling and therefore contracting of 108 Studies in Theology. the earth, greater in the interior than the exterior, in con sequence of which the face of the old earth is become wrinkled. Or, to express it a little more fully, by the greater interior con traction the exterior crust is subjected to enormous lateral pressure, which crushes it together and swells it upward along certain lines, the strata, by the pressure, beiug at the same time thrown into more or less complex foldings. These lines of upswelled and folded strata are mountain ranges. The first grand forms thus produced are afterward chiseled down and sculptured to their present diversified conditions by means of aqueous agency.* Now it remains to examine the result and calculate the time occupied in bringing it about. Our only search now is after the time measures of the process. We are not at all preparing an examination of other questions which pertain to geology. For this the reader must refer to scientific treatises such as Dawson's Earth and Man, Winchell's Walks and Talks in the Geological Field, Elements of Geology by Le Conte. This latter book is exhaustive and most able. A word before we trace the process, that we may be prepared for the examination. We have been so long accustomed to imagine that the earth and heavens were made and completed in a brief time, and by direct agency, that we need to remember a few facts which have been already hinted at before we advance to the consideration of matters now to be introduced. We have already called your attention to positive proof that instead of a brief time millions of years have been employed in the formative Avork of the universe. This point is established already by the discovery of the time consumed in the transit of light from the remotest nebula brought under observation by the telescope. It is no more a question. * See Le Conte's Elements of Geology. Time Measures of the Universe. 109 We now adduce other facts which require the supposition in order to their explanation. You are prepared, therefore, to admit vast ages of time, to explain phenomena, and will not be disturbed when we assume it as already established, Avhile at the same time we point out processes which not only require such immense periods, but also demonstrate the fact. When we are freed from the delusion that time history is short, and are ready to concede an immense period to it, we shall be able to deal with the facts which we encounter in the study of the earth. When we discover phenomena that under the normal operation of the forces by which they were apparently produced required millions of years, having found absolute proof that the history has been developing through such measures, we Avill not find occasion to reduce the period to a less measure. Had the earth been created a globe of matter substantially as we find it in respect of distribution of land and water, and in the elements which compose it, so that the ancient seas had always maintained their places and the dry land had also occu pied the same position it at first held, the principal phenomena in its crust, could they be discovered, could not be explained, nor would it be possible for many of them to exist, and also there Avould be no means of arriving at its probable age, or even to determine that it had existed more than a brief period as com pared with geological eons. Its dry land, which can alone be examined, would have presented no such appearance and no such facts as are now presented. There might, indeed, have been mountains lifted by internal fires, and deep gorges and river beds cut through soils and rocks by the action of rains, and slight surface changes produced by chemical agents and other surface effects, but there would have been no accessible stratified rocks to tell the story of the ages of their formation and varied conditions under which they Avere made ; or fossil con tents revealing the history of life ; or coal measures serviceable 110 Studies in Theology. to the uses of man ; or indeed any of the phenomena which we now perceive, except possibly those of volcanic origin and those produced by atmospheric, organic, and aqueous agency in form ing the soils and in furrowing the surface into river beds. All stratification would have been carried on under the oceans and seas, and we should not, perhaps, even have dreamed of their existence; the supposition itself, though long entertained, is beset with other insuperable difficulties. The proof, as we shall see, is that the history has not been that. The earth is, indeed, the same as to its substances and forces, but the proof is that in respect of size and surface phenomena it has been the scene of perpetual changes, dry land and oceans often changing places, and inorganic and organic changes chasing each other over im measurable ages. But had the two portions remained unchanged, land Avhere the land was first placed, and water where the water was first placed, and the quiet forces left to work their effects, this would have been one of them : the dry land would have been con stantly loAvered until it came to the water level and became submerged, or it must have been constantly uplifted so as to preserve its relative level. In either case we should have found it impossible to determine anything of the probable duration of the process, and carbonifera would have been impossible. This further result would have followed : there would have been a perfect series in their exact order of stratification under the oceanic waters, each geological period depositing itself upon that which immediately preceded. Allowing, as we now find it, that there was a long period during which there Avas no life upon the planet, could we get a cross section of the deportations into the sea, or sedimentation by the sea, we should have a corresponding stratum, in Avhich there would be no fossils, there being no life or organic remains. AlloAving the history of ages of life to have been just Time Measures of the Universe. m as it has been, we would then find overlying this forty thousand feet of unfossiliferous rock the complete series of strata up to date. Following the unstratified igneous foundation would have been the metamorphic deposits, formerly known as the primary azoic period, but now, as more comprehensive, the lau- rentian system and archaean era ; ascending into the first forms of life, called by Darwin and others the eozoic age. Then Ave should find without a gap or break the complete paleozoic era ; comprising in their order the silurian system — lower and upper the devonian, the carboniferous, the permian. We should then have what was formerly knoAvn as the old tertiary, but mod- ernly called mesozoic age, comprising cretaceous, Jurassic, and triassic formations. Then, rising to the most recent geological period, we should find neozoic deposits, eocene, miocene, plio cene, postpliocene, modern — the quaternary group. But, as we shall see by irresistible proof, such has not been the history of the earth. The continents have not always been continents, or the oceans and seas always oceans and seas. They have many times changed place. Present seas and oceans roll over many buried continents, or parts of continents, whose memorials we cannot reach. Present continents have been many times and for long ages submerged. It may be allowed as probable that the present continents and oceans occupy sub stantially their primitive position, the oceans often engulfing parts of the continents and uplifting other parts that had been submerged. It is this series of changes that puts us in posses sion of the earth's story. The records Arere made under the waters for the most part. We are able to trace the writing by having the once submerged page lifted up and spread out on the dry land, portions of it being found here and portions yonder, and possibly large portions entirely lost. Let us see how this is ; and that it is. We have already ' A. 112 Studies in Theology. referred to the stratified rocks and to the fact that these Avere laid in the waters. Before we proceed more particularly to examine the story they relate Ave now call your attention to the fact that there are more ancient unstratified rocks, upon which they are built. Of these more ancient rocks we shall speak further on, and how they came and the story they tell. For the present we assert that all stratified rocks are laid down on unstratified bases. Stratification, therefore, marks a line of new facts in the history of world growth, and like the annular rings of trees, or physiological changes in animals, records growth and age. Stratified rocks, we have said, are made in water by deporta tion of material and by sedimentation found in solution in situ, but chiefly by the former. This is a well-known and universally conceded fact. The sedimentation is affected by the extent and force of agitation and volume and SAviftness of currents, and coarseness or fineness of material deposited. In quiet waters the texture is attenuate and the laminae fine grained and evenly laid ; in turbulent waves or currents coarser and more irregular in volume and form. The growth is constant and gradual, and, as to age, determinable by measurable agencies employed in their production, and by their nonfossiliferous or fossiliferous contents. Any portion of the earth's crust that may at the time be submerged either under shallow swamps or lakes or estuaries, or under deep seas, may be recipients of sedimentation, and the sediment is determinable whether laid in fresh or saline waters. No portion of the earth elevated above water becomes stratified, but is always subject to Avaste and denudation, both by the action of wind and rainfalls and other causes. Wind waves over naked plains and higher lands transport loose and fine sands and pile them in heaps which simulate stratification, but are easily distinguishable ; but this effect is mainly confined to Time Measures of the Universe. 113 seashores Avhere immense drifts accumulate. The overfloAvin* of rivers, inundating vast marginal bottom lands, leave deposits Avhich in the course of ages increase into many feet of earth. In these various ways stratified accumulations are piled on the primitive foundations of the world. The extent of these changes indicates the time measures of world growth since the solid crust was formed. But now, before we come to examine the result in this direc tion, let us turn to examine how the primitive crust itself is formed, and see what light it sheds on the question of the time measure of world growth. If the unstratified under floor on which the stratified rocks are piled may be supposed to have been made instantaneously, the age of the world would be simply the time con- Vostnaaea sumed in the piling up of the stratified deposits ; but un(ler floor- if time was also consumed in making the primitive substructure, that must also be considered, and it may appear that an im measurably greater time was consumed in this first stage than in the second. It is entirely certain that the unstratified antedate the stratified rocks, and that the latter are made out of the former by dis integration and deportation. This needs no proof. Is there any way by which we can determine how these older forms; were produced, and whether instantaneously or by long process-?- There are abundant facts which give light on this subject,. and to some of these we now call attention. The unstratified are distinguished from the stratified' (a) by position ; (I) by the absence of true stratification ; (c) by a crys talline structure ; and (d) by a total absence of fossils. They give evidence that they have been consolidated from a fused or semifused condition, and are hence called igneous rocks. This origin is clearly shown by their structure and by 114 Studies in Theology. the occurrence in them of dikes and tortuous veins, and by the effects produced on contactual stratified rocks, and by their like ness to lavas. They underlie the strata wherever found over the whole globe, and reach as far down as can be penetrated toward the interior of the globe ; they form the peaks and apexes of mountain ranges, and fill the fissures and veins of fractured overlying stratified rocks, into which they could only be intro duced in a state of fusion. These universal characteristics lead to the conclusion that the globe itself was primitively a molten mass, of whicli the exterior was formed into a solid crust by radiation of heat and refrigeration. This theory finds support in these further facts : (a) by the oblate spheroidal form of the earth ; (I) the baked, wrinkled, contorted, and semicrystalline condition of the stratified rocks immediately overlying the unstratified base all the earth over, except when the strata is of a much later age — the oldest strata are invariably transformed by evident heat agency; (c) the volcanic phenomena found in all parts of the globe even to this day ; (d) the increase of temperature as we descend in the crust, showing that at a fixed depth all substances would be reduced to a molten or fluid state ; (
