SPECULATORS AMONG THE STARS.[1]
Whatever we talk, Things areas they are—not as we grant, dispute, or hope; depending on neither our affirmative nor negative.[2]—Jeremy Taylor.
Let us bear in mind the above passage, pregnant with solemnising reflection, while dealing with the question before us; always remembering that it is one purely speculative, however interesting, however exciting, to imaginative persons; but to weak and superficial ones—to those of unsettled opinions—capable of becoming mischievous.
The state of that question is exactly this: The heavenly bodies around us, some or all of them, are, or are not, in point of fact, the abodes of intellectual and moral beingslike ourselves—that is, be it observed, consisting of body and soul. That there are other and higher orders of intelligent existence, both the Christian and the mere philosopher may, and the former must, admit as an article of his “creed;” but what may be the mode of that existence, and its relations to that physical world of which we are sensible, we know not, and conjecture would be idle. That beings like ourselves exist elsewhere than here, is not revealed in Scripture; and the question, consequently, for us to concern ourselves with is, whether there nevertheless exist rational grounds for believing the fact to be so. The accomplished and eminent person who has so suddenly started this discussion, has, since hisEssayappeared,[3]and in strict consistency with it, emphatically declared—“I do not pretend to disprove a plurality of worlds; but I ask in vain for any argument which makes the doctrine probable. And as I conceive the unity of the world to be the result of its being the work of one Divine Mind, exercising creative power according to His own Ideas; so it seems to me not unreasonable to suppose that man, the being which can apprehend, in some degree, those Ideas, is a creature unique in the creation.” But what says Sir David Brewster, speaking of the greatest known member of our planetary system, Jupiter?
“With so many striking points of resemblance between the Earth and Jupiter, the unprejudiced mind cannot resist the conclusion, that Jupiter has been created, like the Earth, for the express purpose of being the seat of animal and intellectual life. The Atheist and the Infidel, the Christian and the Mahommedan, men of all creeds, nations, and tongues, the philosopher and the unlettered peasant, have all rejoiced in this universal truth; and we do not believe that any individual who confides in the facts of astronomy seriously rejects it. If such a person exists, we would gravely ask him, for what purpose could so gigantic a world have been framed?”[4]
I am such a person, would say Dr Whewell, and I declare that I cannot tell why Jupiter was created. “I do not pretend to know for what purpose the stars were made, any more than the flowers, or the crystalline gems, or other innumerable beautiful objects.... No doubt the Creator might make creatures fitted to live in the stars, or in the small planetoids, or in the clouds, or on meteoric stones; but we cannot believe that hehasdone this, without further evidence.”[5]And as to the “facts of astronomy,” let me patiently examine them, and the inferences you seek to deduce from them. Besides which, I will bring forward certain facts of which you seem to have taken no account.
As we foresaw, Dr Whewell’sEssayis attracting increased attention in all directions; and, as far as we can ascertain the scope of contemporaneous criticism hitherto pronounced, it is hostile to his views, while uniformly recognising the power and scientific knowledge with which they are enforced. “We scarcely expected,” observes an accomplished diurnal London reviewer,[6]“that in the middle of the nineteenth century, a serious attempt would have been made to restore the exploded ideas of man’s supremacy over all other creatures in the universe; and still less that such an attempt would have been made by any one whose mind was stored with scientific truths. Nevertheless a champion has actually appeared, who boldly dares to combat against all the rational inhabitants of other spheres; and though as yet he wears his vizor down, his dominant bearing, and the peculiar dexterity and power with which he wields his arms, indicate that this knight-errant of nursery notions can be no other than the Master of Trinity College, Cambridge.” The reviewer falls, it appears to us, into a serious error as to the sentiments of Dr Whewell, when charging him with requiring us “to assume that, in the creation of intelligent beings, Omnipotence must be limited, in its operations, to the ideas which human faculties can conceive of them: that such beings must be men like ourselves, with similar powers, and have had their faculties developed by like means.” In the very passage cited to support this charge, Dr Whewell will be found thus exactly limiting his proposition so as to exclude so impious and absurd a supposition:—“In order to conceive, on the Moon, or on Jupiter, a race of beings intelligentlike man, we must conceive there colonies of men, with histories resembling, more or less, the histories of human colonies: and, indeed, resembling the history of those nations whose knowledge we inherit, far more closely than the history of any other terrestrial nation resembles that part of terrestrial history.”[7]In the passage which we have quoted in the preceding column, Dr Whewell expressly declares, as of course he could not help declaring, that the Creator no doubt might make creatures fitted to live on the stars, or anywhere; but the passage misunderstood by the reviewer, appears to us possessed of an extensive significance, of which he has hastily lost sight, but which is closely connected with that portion of the author’s speculations with which we briefly dealt in our last number, especially that which regards Man as a being of progressive[8]development. To this we shall hereafter return, reminding the reader of the course of Dr Whewell’s argument as thus far disclosed—namely, that man’s intellectual, moral, religious, and spiritual nature, is of so peculiar and high an order, as to warrant our regarding him as a special and unique existence, worthy of the station here assigned him in creation. Intellectually considered, man “has an element of community with God: whereupon it is so far conceivable that man should be, in a special manner, the object of God’s care and favour. The human mind, with its wonderful and perhaps illimitable powers, is something of which we can believe God to be mindful:”[9]that He may very reasonably be thus mindful of a being whom he has vouchsafed to make in his own Image, after His likeness—the image and likeness of the awful Creator of all things.
“The privileges of man,” observes Dr Whewell, in a passage essential to be considered by those who would follow his argument,[10]“which make the difficulty in assigning him his place in the Vast Scheme of the universe, we have described as consisting in his being anIntellectual, Moral, and Religiouscreature. Perhaps the privileges implied in the last term, and their place in our argument, may justify a word more of explanation.... We are now called upon,” proceeds the Essayist, after a striking sketch of the character and capacity of man, especially as a spiritual creature, “to proceed to exhibit the Answer which a somewhat different view of modern science suggests to this difficulty or objection.”
—“The difficulty[11]appears great either way of considering it. Can the earth alone be the theatre of such intelligent, moral, religious, and spiritual action? Or can we conceive such action to go on in the other bodies of the universe?... Between these two difficulties the choice is embarrassing, and the decision must be unsatisfactory, except we can find some further ground of judgment. But this, perhaps, is not hopeless. We have hitherto referred to the evidence and analogies supplied by one science, namely, Astronomy. But there are other sciences which give us information concerning the nature and history of the Earth. From some of these we may perhaps obtain some knowledge of the place of the Earth in the scheme of creation; how far it is, in its present condition, a thing unique, or only one thing among many like it. Any science which supplies us with evidence or information on this head, will give us aid in forming a judgment upon the question under our consideration.”
Thus the Essayist reaches the second stage of his inquiry, entering on the splendid domain ofGeology. To this great but recently consolidated science Dr Chalmers made no allusion in his celebrated “Discourses on the Christian Revelation, viewed in connection with the Modern Astronomy,”[12]which were delivered in the year 1817, nearly thirty-seven years ago: and then he spoke, in his first Discourse, of Astronomy as “the most certain and best established of the sciences.” Dr Whewell, however, vindicates the claims of Geology, in respect of both the certainty and vastness of her discoveries, in a passage so just and admirable, that we must lay it before our readers.
“As to the vastness of astronomical discoveries, we must observe that those of Geology are no less vast: they extend through time, as those of Astronomy do through space; they carry us through millions of years—that is, of the earth’s revolutions—as those of Astronomy through millions of the earth’s diameters, or of diameters of the earth’s orbit. Geology fills the regions of duration with events, as Astronomy the regions of the universe with objects. She carries us backwards by the relation of cause and effect, as Astronomy carries us upwards by the relations of geometry. As Astronomy steps on from point to point of the universe by a chain of triangles, so Geology steps from epoch to epoch of the earth’s history by a chain of mechanical and organical laws. If the one depends on the axioms of geometry, the other depends on the axioms of causation.... But in truth, in such speculations, Geology has an immeasurable superiority. She has the command of an implement, in addition to all that Astronomy can use; and one, for the purpose of such speculations, adapted far beyond any astronomical element of discovery. She has, for one of her studies,—one of her means of dealing with her problems,—the knowledge of life, animal and vegetable. Vital organisation is a subject of attention which has, in modern times, been forced upon her. It is now one of the main parts of her discipline. The geologist must study the traces of life in every form—must learn to decipher its faintest indications and its fullest development. On the question, then, whether there be, in this or that quarter, evidence of life, he can speak with the confidence derived from familiar knowledge; while the astronomer, to whom such studies are utterly foreign, because he has no facts which bear upon them, can offer, on such questions, only the loosest and most arbitrary conjectures, which, as we have had to remark, have been rebuked by eminent men as being altogether inconsistent with the acknowledged maxims of his science.”[13]
Before we proceed to state the singular and suggestive argument derived from this splendid science,[14]we may apprise the reader that Dr Whewell’s primary object is to show, that even “supposing the other bodies of the universe to resemble the earth, so far as to seem, by their materials, forms, and motions, no less fitted than she is to be the abodes of life, yet that, knowing what we know of Man, we can believe the earth to be tenanted by a race who are thespecialobjects of God’s care.”[15]The grounds for entertaining, or rather impugning, that supposition he subsequently deals with after his own fashion in ChaptersVII.,VIII.,IX.,X.; but the two with which we are at present concerned are the fifth and sixth, respectively entitled, as we intimated in our last Number, “Geology,” and “The Argument from Geology.”
The exact object at which this leading section of the Essay is aimed is, in the Essayist’s words, this:—“A complete reply to the difficulty which astronomical discoveries appeared to place in the way of religion:—the difficulty of the opinion that Man, occupying this speck of earth but as an atom in the universe, surrounded by millions of other globes larger, and to all appearance nobler, than that which he inhabits, should be the object of the peculiar care and guardianship of the favour and government of the Creator of All, in the way in which religion teaches us that he is.”[16]
What is that “complete reply?” The following passage contains a key to the entire speculation of the Essayist, and deserves a thoughtful perusal:—
“That the scale of man’s insignificance isof the same order in reference to time as to space. That Man—the Human Race from its origin till now—has occupied but an atom of time as he has occupied but an atom of space.”... “If the earth, as the habitation of Man, is a speck in the midst of an infinity of space, the Earth, as the habitation of Man, is also a speck at the end of an infinity of time. If we are as nothing in the surrounding universe, we are as nothing in the elapsed eternity; or rather in the elapsed organic antiquity during which the Earth has existed, and been the abode of life. If Man is but one small family in the midst of innumerable possible households, he is also but one small family, the successor of innumerable tribes of animals, not possible only, but actual. If the planets may be the seats of life, we know that the seas, which have given birth to our mountains, were so. If the stars may have hundreds of systems of tenanted planets rolling round them, we know that the secondary group of rocks does contain hundreds of tenanted beds, witnessing of as many systems of organic creation. If the Nebulæ may be planetary systems in the course of formation, we know that the primary and transition rocks either show us the earth in the course of formation, as the future seat of life, or exhibit such life as already begun.
“How far that which Astronomy thus asserts as possible, is probable—what is the value of these possibilities of life in distant regions of the universe, we shall hereafter consider; but in what Geology asserts, the case is clear. It is no possibility, but a certainty. No one will now doubt that shells and skeletons, trunks and leaves, prove animal and vegetable life to have existed. Even, therefore, if Astronomy could demonstrate all that her most fanciful disciples assume, Geology would still have a complete right to claim an equal hearing—to insist on havingher analogiesregarded. She would have a right to answer the questions of Astronomy, when she asks, How can we believe this? And to have her answer accepted.”[17]
We regret that our space prevents our laying before the reader the masterly and deeply interesting epitome of geological discoveries contained in these two chapters. The stupendous series of these revelations may be thus briefly indicated:—That countless tribes of animals tenanted the earth for countless ages before Man’s advent; that former ocean-beds now constitute the centres of our loftiest mountains, as the results of changes gradual, successive, and long continued; that these vast masses of sedimentary strata present themselves to our notice in a strangely disordered state; that each of these rocky layers contains a vast profusion of the remains of marine animals, intermingled with a great series of fresh-water and land animals and plants endlessly varied—all these being different, not only in species, but in kind!—and each of these separate beds must have lasted as long, or perhaps longer, than that during which the dry land has had its present form.
The careful prosecution of their researches has forced on the minds of geologists and naturalists “the general impression that, as we descend in this long staircase of natural steps, we are brought in view of a state of the earth in which life was scantily manifested, so as to be near its earliest stages.”[18]
In the opinion of the most eminent geologists, some of these epochs of organic transition were also those of mechanical violence, on a vast and wonderful scale—as it were, a vast series of successive periods of alternate violence and repose. The general nature of such change is vividly sketched by the Essayist, in a passage to which we must refer the reader.[19]When, continues the Essayist, we find strata bearing evidence of such a mode of deposit, and piled up to the height of thousands and tens of thousands of feet, we are naturally led to regard them as the production of myriads of years; and to addnewmyriads, as often as we are brought to new masses of strata of the like kind; and again to interpolate new periods of the same order, to allow for the transition from one group to another.[20]
The best geologists and naturalists are utterly at fault, in attempting to account for the successive introduction of these numerousnew species, at these immense intervals of time, except by referring them to the exercise of a series of distinct Acts of Creation. The chimerical notion of some natural cause effecting a transmutation of one series of organic forms into another, has been long exploded, as totally destitute of proof: and “the doctrine of the successiveCREATIONof species,” says the Essayist, “remains firmly established among geologists.”[21]There is nothing known of the cosmical conditions of our globe, to contradict the terrestrial evidence for its vast antiquity as the seat of organic life,[22]says Dr Whewell: and then proceeds thus, in a passage which is well worth the reader’s attention, and has excited the ire of Sir David Brewster:—
“If, for the sake of giving definiteness to our notions, we were to assume that the numbers which express the antiquity of these four periods—the present organic condition of the earth; the tertiary period of geologists which preceded that; the secondary period which was anterior to that; and the primary period which preceded the secondary—wereon the same scaleas the numbers which express these four magnitudes:—The magnitude of the earth; that of the solar system compared with the earth; the distance of the nearest fixed stars compared with the solar system; and the distance of the most remote nebulæ compared with the nearest fixed stars,—there is, in the evidence which geological science offers, nothing to contradict such an assumption. And as the infinite extent which we necessarily ascribe to space allows us to find room, without any mental difficulty, for the vast distances which astronomy reveals, and even leaves us rather embarrassed with the infinite extent which lies beyond our furthest explorations; so the infinite duration which we, in like manner, necessarily ascribe to past time, makes it easy for us, so far as our powers of intellect are concerned, to go millions of millions of years backwards, in order to trace the beginning of the earth’s existence—the first step of terrestrial creation.”
To return, however, to the course of the argument. We hear the oppressed observer asking, as he reascends this “long staircase of natural steps” which had brought time down to the mystic origin of animal existence; his eye dimmed with its efforts to “decipher,” in the picturesque language of Sir David Brewster, “downwards, the pale and perishing alphabet[23]of the Chronology of Life”—where, all this while, was Man?
Were Europe at this moment to be submerged beneath the ocean, or placed under a vast rocky stratum, what countless proofs would present themselves to the exploring eyes of remote future geologists, of the existence of both Man and his handiwork!—of his own skeleton, of the products of his ingenuity and power, and the various implements and instruments with which he had effected them!
The rudest conceivable work of human art would carry us to any extent backward, but it is not to be found! Man’s existence and history incontestably belong to the existing condition of the earth; and the Essayist now addresses himself to the two following propositions:—
First, That the existence and history of man are facts of an Entirely Different Order from any which existed in any of the previous states of the earth.
Secondly, That his history has occupied a series of years which, compared with geological periods, may be regarded as very brief and limited.
Here opens the “Argument from Geology”—and with it Chapter VI.
That the existence of man upon the earth is an event of an order quite different from any previous part of the earth’s history; and that there is no transition from animals toMAN, in even his most degraded, barbarian, and brutish condition, the Essayist demonstrates, with affecting eloquence, and with great argumentative power. No doubt there are kinds of animals very intelligent and sagacious, and exceedingly disposed and adapted to companionship with man; but by elevating the intelligence of the brute, we do not make it become that of the man; nor by making man barbarous, do we make him cease to be man. He has a capacity, not for becoming sagacious, butrational,—or rather he has a capacity forPROGRESS, in virtue of his being rational.
After adverting to Language, as an awful and mysterious evidence of his exalted endowments, and felicitously distinguishing instinct from reason, the Essayist observes that we need not be disturbed in our conclusions by observing the condition of savage and uncultivated tribes, ancient or modern—the Scythians and Barbarians, the Australians and Negroes. The history of man, in the earliest times, is as truly a history of a wonderful, intellectual, social, political, spiritual creature, as it is at present.[24]The savage and ignorant state is not the state of nature out of which civilised life has everywhere emerged: their savage condition is one rather of civilisation degraded and lost, than of civilisation incipient and prospective. And even were it to be assumed to be otherwise, that man, naturally savage, had a tendency to become civilised, thatTENDENCYis an endowment no less wonderful than those endowments which civilisation exhibits.
When, however, we know not only what man is, but what hemay become, both intellectually and morally, as we have already seen; when we cast our mind’s eye over the history of the civilised section of our race, wherever authentic records of their sayings and doings exist, we find repeated and radiant instances of intellectual and moral greatness, rising into sublimity—such as compel us to admit that man is incomparably the most perfect and highly endowed creature which appears to have ever existed on the earth.
“How far previous periods of animal existence were a necessary preparation of the earth as the habitation of man, or a gradual progression towards the existence of man, we need not now inquire. But this, at least, we may say, that man, now that he is here, forms a climax to all that has preceded—a term incomparably exceeding in value all the previous parts of the series—a complex and ornate capital to the subjacent column—a personage of vastly greater dignity and importance than all the preceding line of the procession.”[25]
If we are thus to regard man as the climax of the creation in space, as in time, “can we point out any characters,” finally asks the Essayist, “which may tend to make it conceivable that the Creator should thus distinguish him, and care for him—should prepare his habitation, if it be so, by ages of chaotic and rudimentary life, and by accompanying orbs of brute and barren matter? If man be thus the head, the crowned head, of the creation, is he worthy to be thus elevated? Has he any qualities which make it conceivable that, with such an array of preparation and accompaniment”—the reader will note the sudden introduction of these elements of the question, the “accompanying orbs!”—“he should be placed upon the earth, his throne? Does any answernowoccur to us, after the views which have been presented to us? That answer,” continues the Essayist, “is the one which has been already given:” “the transcendent intellectual, moral, and religious character of man—such as warrants him in believing that God, in very deed, is not only mindful of him, but visits him.”[26]
This may be, the objector is conceived to say; but my difficulty haunts and harasses me: that, while man’s residence is, with reference to the countless glistening orbs revealed by Astronomy, scarcely in the proportion of a single grain of sand to the entire terraqueous structure of our globe, I am required to believe that the Almighty has dealt with him, and with the speck in which he resides, in the awfully exceptional manner asserted in the Scriptures. Let us here remind the reader of a coarser, and an insolent and blasphemous, expression of this “difficulty,” by Thomas Paine, already quoted:—[27]
“The system of a plurality of worlds renders the Christian faith at once little and ridiculous, and scatters it in the mind like feathers in the air: the two beliefs cannot be held together in the same mind.” With such an opponent Dr Whewell expressly states that he has no concern; he deals with a “‘difficulty’ felt by a friend:” wishing “rather to examine how to quiet the troubled and perplexed believer, than how to triumph over the dogmatical and self-satisfied unbeliever.”
“Let the difficulty,” he says, “be put in any way the objector pleases.”
I. Is it that it is unworthy of the greatness and majesty of God, according to our conception of Him, to bestow such peculiar care on soSMALL A PARTof His creation?[28]
But a narrow inspection of the atom of space assigned to man, proves that Hehasdone so. He has made the period of mankind, though only a moment in the ages of animal life, the only period of Intelligence, Morality, Religion. If it be contrary toOUR!conception of Him, to suppose Him to have done so, it is plain that these conceptions are wrong. God has not judged as to what is worthy of Him, as we have presumed to judge. He has deemed it worthy of Himself to bestow upon man this special care, though he occupy so small a portion ofTIME:—why not, then, though he occupy so small a portion ofSPACE?
II. Is the difficulty this:—That supposing the earth, alone, to be occupied by inhabitants, all the other globes of the universe areWASTED?—turned toNO PURPOSE?[29]
Is “waste” of this kind to be considered unsuited to the character of our Creator? But here again we have the like “waste” in the occupation of this earth! All its previous ages, its seas and its continents, have been “wasted” upon mere brute life: often, apparently, on the lowest, the least conscious forms of life:—upon sponges, coral, shell-fish. Why, then, should not the seas and continents of other planets be occupied with life of this order, or with no life at all? Who shall tell how many ages elapsed before this earth was tenanted by life at all? Will the occupation of a spot of land, or a little water, by the life of a sponge, a coral, or an oyster, save it from being “wasted”? If a spot of rock or water be sufficiently employed by its being the mere seat of organisation, of however low and simple a type,—why not, by its being the mere seat of attraction? cohesion? crystalline power? All parts of the universe appear pervaded by attraction, by forces of aggregation and atomic relation, by light and heat: why may not these be sufficient, in the eyes of the Creator, to prevent the space from being “wasted,” as, during a great part of the earth’s past history, and over vast portions of its mass in its present form, they are actually held by Him to be sufficient? since these powers, or forces, are all that occupy such portions. This notion, therefore, of the improbability of there being in the universe so vast an amount of “waste” spaces, or “waste” bodies, as is implied in the notion that the earth alone is the seat of life, or of intelligence, is confuted by matter-of-fact, existing, in respect of vast spaces, waste districts, and especially waste times, upon our own earth. Theavoidanceof such “waste,” according to our notions of waste, is no part of the economy of creation, so far as we can discern that economy in its most certain exemplification.
III. Is the difficulty this:—That giving such a peculiar dignity and importance to the earth iscontrary to the Analogy of Creation?[30]
This objection, be it observed,assumesthat there are so many globes similar to the earth, and like her revolving,—some accompanied as she is, by satellites,—on their axis, and that therefore it is reasonable to suppose the destination and office of all, the same;—that there are so many stars, each, like our sun, a source of light, probably also of heat; and that it is consequently reasonable to suppose their light and heat, like his, imparted, as from so many centres of systems, to uphold life;—and that all this affords strong ground for believing all such planets, as well those of our own as of other systems, inhabited like our planet.
But the Essayist again directs the eye of the questioner to the state of our own planet, as demonstrated by Geology, in order to show the precariousness, if not futility, of supposing such an analogy to exist. It would lead us to a palpably false conclusion—viz., that during all the vast successive periods of the Earth’s history, that Earth was occupied with life of the same order—nay, even, that since the Earth is now the seat of an intelligent population, it must have been so in all its former conditions. For it was then able, and adapted, to support animal life, and that of creatures pretty closely resembling man[31]in physical structure. Nevertheless, if evidence go for anything, the Earth did not do so! “Even,” says Dr Whewell, “those geologists who have dwelt most on the discovery of fossil monkeys, and other animals nearest to man, have not dreamed that there existed, before him, a race of rational, intelligent, and progressive creatures.”[32]Here, however, he is mistaken, as we shall presently see Sir David Brewster revelling in such a dream. As, then, the notion that one period of time in the Earth’s history must resemble another in the character of its population, because it resembles it in physical conditions, is negatived by the history of the Earth itself; so the notion that one partof the universemust resemble another in its population, because it has a resemblance in physical conditions, is negatived, as a law of creation. Analogy really affords no support to such a notion.
IV. Nay, continues Dr Whewell,[33]we may go further: instead of the analogy of creation pointing to such entire resemblance of similar parts, it points in the opposite direction: it is not entire resemblance, but universal difference, that we discover: not the repetition of exactly similar cases, but a series of cases perpetually dissimilar, presents itself: not constancy, but change—perhaps advance; not one permanent and pervading scheme, but preparation, and completion of successive schemes:—not uniformity, and a fixed type of existences, but progression and a climax.
Viewing the advent of Man, and what preceded it, it seems the analogy of nature that there should be inferior, as well as superior, provinces in the universe, and that the inferior may occupy an immensely larger portion of Time than the superior. Why not, then, of Space?
“The earth was brute and inert, compared with its present condition; dark and chaotic, so far as the light of reason and intelligence are concerned, for countless centuries before man was created. Why then may not other parts of creation be still in this brute and inert and chaotic state, while the earth is under the influence of a higher exercise of creative power? If the earth was for ages a turbid abyss of lava and of mud, why may not Mars or Saturn be so still?... The possibility that the planets are such rude masses, is quite as tenable, on astronomical grounds, as the possibility that the planets resemble the earth, in matters of which astronomy can tell us nothing. We say, therefore, that the example of geology refutes the argument drawn from the supposed analogy of one part of the universe with another; and suggests a strong suspicion that the force of analogy, better known, may tendin the opposite direction.”[34]
We have now gone through a large portion, embracing two of the three sections into which we had divided this startlingEssay; presenting as full and fair an account of it as is consistent with our limits. Though the author professes that he “does not pretend to disprove the Plurality of Worlds, but to deny the existence of arguments making the doctrine probable,” his undisguised object is to assign cogent reasons for holding the opposite to be the true doctrine—the Unity of the World. What has gone before is, moreover, on the assumption that the other bodies of the universe are fitted, equally with the Earth, to be the abodes of life. Before passing on, however, to the remaining section of theEssay, which is decidedly hostile to that assumption, let us here introduce on the scene Dr Whewell’s only hitherto avowed antagonist, Sir David Brewster.
Though it is impossible to treat otherwise than with much consideration, whatever is published by this gentleman, we must express our regret that he did not more deliberately approach so formidable an opponent as Dr Whewell, and, as we are compelled to add, in a more calm and courteous spirit. We never read a performance less calculated than thisEssay, from its modesty and moderation of tone, and the high and abstract nature of the topics which it discusses with such powerful logic, and such a profusion of knowledge of every kind, to provoke an acrimonious answer. It is happily rare, in recent times, for one of two philosophic disputants, to speak of the other’s “exhibiting an amount of knowledge so massive as occasionally to smother his reason;”[35]“ascribing his sentiments only to some morbid condition of the mental powers, which feeds upon paradox, and delights in doing violence to sentiments deeply cherished, and to opinions universally believed;”[36]characterising some of his reasonings as “dialectics in which a large dose of banter and ridicule is seasoned with a little condiment of science;”[37]and an elaborate argument, of great strength and originality, whether sound or not, as “the most ingenious, though shallow piece of sophistry, whichwe!(Sir David Brewster) have encountered in modern times;”[38]referring his “theories and speculations to no better a feeling than a love of notoriety.”[39]It is not to be supposed that Sir David was not perfectly aware who his opponent was,[40]which occasions extreme surprise at the tone adopted throughoutMore Worlds than One. In his preface, he explains as a cause of his anger, that he found that “the author” of theEssay, “under a title calculated to mislead the public, had made an elaborate attack upon opinions consecrated, as Sir David had thought, by reason and revelation,”—that the author had not only adopted a theory (the Nebular) so universally condemned as a dangerous speculation, “but had taken a view of the condition of the solar system calculated to disparage the science of astronomy, and throw a doubt over the noblest of its truths.” We dismiss this topic with a repetition of our regret, that so splendid a subject was not approached in a serener spirit; that greater respect was not shown by one of his contemporaries for one of the most eminent men of the age; and that sufficient time was not taken, in order to avoid divers surprisingmaculæoccurring in even the composition, and certain rash and unguarded expressions and speculations.
If Dr Whewell may be regarded as (pace tanti viri!) a sort of Star-Smasher, his opponent is in very truth a Star-Peopler. Though he admits that “there are some difficulties to be removed, and some additional analogies to be adduced, before the mind can admit the startling proposition[41]that the Sun, Moon, and all the satellites, are inhabited spheres”—yet he believes that they are:[42]that all the planets of their respective systems are so; as well as all the single stars, double stars, and nebulæ, with all planets and satellites circling about them!—though “ourfaltering reason utterly failsus!” he owns,[43]“when called on to believe that even theNebulæmust be surrendered to life and reason! Wherever there is matterthere mustbe life!” One can by this time almost pardon the excitement, the alarm rather, and anger, with which Sir David ruefully beheld Dr Whewell go forth on his exterminating expedition through Infinitude! It was like a father gazing on the ruthless slaughter of his offspring. Planet after planet, satellite after satellite, star after star, sun after sun, single suns and double suns, system after system, nebula after nebula, all disappeared before this sidereal Quixote! As for Jupiter and Saturn, the pet planets of Sir David, they were dealt with in a way perfectly shocking. The former turned out, to the disordered optics and unsteady brain of the Essayist, to be a sphere of water, with perhaps a few cinders at the centre, and peopled “with cartilaginous and glutinous monsters—boneless, watery, pulpy creatures, floating in the fluid;” while poor Saturn may be supposed turning aghast on hearing that, for all his grand appearance, he was little else than a sphere of vapour, with a little water, tenanted, if at all, by “aqueous, gelatinous creatures—too sluggish almost to be deemed alive—floating in their ice-cold waters, shrowded for ever by their humid skies!” But talk after this of the pensive Moon! “She is a mere cinder! a collection of sheets of rigid slag, and inactive craters!” This could be borne no longer; so thus Sir David pours forth the grief and indignation of the Soul Astronomic, in a passage fraught with the spirit, and embodying the results, of his whole book, and which we give, as evidently laboured by the author with peculiar care.
“Those ungenial minds that can be brought to believe that the earth is the only inhabited body in the universe, will have no difficulty in conceiving that it also might have been without inhabitants. Nay, if such minds are imbued with geological truth, they must admit that for millions of years the earth was without inhabitants; and hence we are led to the extraordinary result, that for millions of years there was not an intelligent creature in the vast dominions of the universal King; and that before the formation of the protozoic strata, there was neither a plant nor an animal throughout the infinity of space! During this long period of universal death, when Nature herself was asleep—the sun, with his magnificent attendants—the planets, with their faithful satellites—the stars in the binary systems—the solar system itself, were performing their daily, their annual, and their secular movements unseen, unheeded, and fulfilling no purpose that human reason can conceive; lamps lighting nothing—fires heating nothing—waters quenching nothing—clouds screening nothing—breezes fanning nothing—and everything around, mountain and valley, hill and dale, earth and ocean, all meaning nothing.
‘The starsDid wander darkling in the eternal space.’
‘The starsDid wander darkling in the eternal space.’
‘The starsDid wander darkling in the eternal space.’
‘The stars
Did wander darkling in the eternal space.’
To our apprehension, such a condition of the earth, of the solar system, and of the sidereal universe, would be the same as that of our own globe if all its vessels of war and of commerce were traversing its seas with empty cabins and freightless holds; as if all the railways on its surface were in full activity without passengers and goods; and all our machinery beating the air and gnashing their iron teeth without work performed. A house without tenants, a city without citizens, present to our minds the same idea as a planet without life, and a universe without inhabitants. Why the house was built, why the city was founded, why the planet was made, and why the universe was created, it would be difficult even to conjecture. Equally great would be the difficulty were the planets shapeless lumps of matter, poised in ether, and still and motionless as the grave. But when we consider them as chiselled spheres, and teeming with inorganic beauty, and in full mechanical activity, performing their appointed motions with such miraculous precision that their days and their years never err a second of time in hundreds of centuries, the difficulty of believing them to be without life is, if possible, immeasurably increased. To conceive any one material globe, whether a gigantic clod slumbering in space, or a noble planet equipped like our own, and duly performing its appointed task, to have no living occupants, or not in a state of preparation to receive them, seems to us one of those notions which could be harboured only in an ill-educated and ill-regulated mind—a mind without faith and without hope: but to conceive a whole universe of moving and revolving worlds in such a category, indicates, in our apprehension, a mind dead to feeling and shorn of reason.”[44]
“It is doubtless possible,” observes Sir David, however, a little further on,[45]as if with a twinge of misgiving, “that the Mighty Architect of the universe may have had other objects in view, incomprehensible by us, than that of supporting animal and vegetable life in these magnificent spheres.” Would that Sir David Brewster would allow himself to be largely influenced by this rational and devout sentiment! His book is, on the contrary, crammed with assertions from beginning to end, and of a peremptory and intolerant character unknown to the spirit of genuine philosophy.
The Essayist, however, is not incapable of quiet humour: and the following pregnant passage is at least worthy to stand side by side with that which we have just quoted from his indignant and eloquent opponent:—
“Undoubtedly, all true astronomers, taught caution and temperance of thought by the discipline of their magnificent science, abstain from founding such assumptions upon their discoveries. They know how necessary it is to be upon their guard against the tricks which fancy plays with the senses; and if they see appearances of which they cannot interpret the meaning, they are content that they should have no meaning for them, till the due explanation comes. We have innumerable examples of this wise and cautious temper in all periods of astronomy. One has occurred lately. Several careful astronomers, observing the stars by day, had been surprised to see globes of light glide across the field of view of their telescopes, often in rapid succession, and in great numbers. They did not, as may be supposed, rush to the assumption that these globes were celestial bodies of a new kind, before unseen, and that, from the peculiarity of their appearance and movement, they were probably inhabited by beings of a peculiar kind. They proceeded differently. They altered the focus of their telescopes, looked with other glasses, made various changes and trials; and finally discovered that these globes of light were the winged seeds of certain plants, which were wafted through the air, and which, illuminated by the sun, were made globular by being at distances unsuited to the focus of the telescopes!”[46]
Before proceeding to give our readers some idea of the mode in which Sir David Brewster encounters Dr Whewell, let us offer a general observation concerning both these eminent gentlemen. While the latter exhibits throughout his Essay a spirit of candour and modesty, without one harsh expression or uncharitable insinuation with reference to the holder of doctrines which he is bent upon impugning with all his mental power and multifarious resources; the former, as we have seen, uses language at once heated, uncourteous, and unjustifiable: especially where he more than insinuates that his opponent, whose great knowledge and ability he admits, either deliberately countenances doctrines tending really to Atheism, or may be believed “ignorantof their tendency, and to have forgotten the truths of Inspiration, and even those of Natural Religion.”[47]To venture, however circuitously, to hint such imputations upon an opponent whom he had the slightest reason to suspect being one of such high and responsible academic position, is an offence equally against personal courtesy and public propriety; as we think Sir David Brewster would, on reflection, acknowledge. Both Dr Whewell and Sir David Brewster must excuse us, if, scanning both through the cold medium of impartial criticism, their speculations, questions, or assertions appear to us disturbed and deflected by a leading prepossession or foregone conclusion, which we shall indicate in the words of each.
DrWhewell.—“The Earth is really the largest Planetary body in the Solar system; its domestic hearth, and the Only World [i. e.collection of intelligent creatures] in the Universe.”[48]
SirDavid Brewster.—“Life is almost a property of matter.... Wherever there is Matter, there must be Life:—Life physical, to enjoy its beauties; Life Moral, to worship its Maker; and Life Intellectual, to proclaim His wisdom and His power.... Universal Life upon Universal matter, is an idea to which the mind instinctively clings.... Every star in the Heavens, and every point in a nebula which the most powerful telescope has not separated from its neighbour, is a sun surrounded by inhabited planets like our own.... In peopling such worlds with life and intelligence, we assign the cause of their existence; and when the mind is once alive to this great Truth, it cannot fail to realise the grand combination of infinity of life with infinity of matter.”[49]
The composition of Sir David Brewster, though occasionally too declamatory and rhetorical, and so far lacking the dignified simplicity befitting the subjects with which he deals, has much merit. It is easy, vivid, and vigorous, but will bear retrenchment, and lowering of tone. As to the substantial texture of his work, we think it betrays, in almost every page, haste and impetuosity, and evidence that the writer has sadly under-estimated the strength of his opponent. Another feature ofMore Worlds than One, is a manifest desireprovocare ad populum—a greater anxiety, in the first instance, to catch the ear of the million, than to convince the “fit audience, though few.” Now, however, to his work; and, as we have already said, on him lies the labouring oar of proof. All that his opponent professes to do, is to ask for arguments “rendering probable” that “doctrine” which Sir David pledges himself to demonstrate to be not only the “hope” of the Christian, but thecreedof the philosopher: as much, that is, an article of his belief, as the doctrines of attraction and gravitation, or the existence of demonstrable astronomical facts.
He commences with a brief introduction, sketching the growth of the belief in a plurality of worlds—one steadily and firmly increasing in strength, till it encountered the rude shock of the Essayist, whose “very remarkable work” is “ably written,” and who “defends ingeniously his novel and extraordinary views:” “the direct tendency of which is to ridicule and bring into contempt the grand discoveries in sidereal astronomy by which the last century has been distinguished.” In his next chapter, Sir David discusses “the religious aspect of the question,” representing man, especially the philosopher, as always having pined after a knowledge of the scene of his future being. He declares that neither the Old nor the New Testament contains “a single expression incompatible with the great truth that there are other worlds than our own which are the seats of life and intelligence;” but, on the contrary, there are “other passages which are inexplicable without admitting it to be true.” He regards, as we have seen, the noble exclamation of the Psalmist, “What is man,” as “a positive argument for a plurality of worlds;” and “cannot doubt” that he was gifted with a plenary knowledge of the starry system, inhabited as Sir David would have it to be! Dr Chalmers, let us remark, in passing, expressed himself differently, and with a more becoming reserve: “It is not for us to say whether inspiration revealed to the Psalmist the wonders of the modern astronomy,” but “even though the mind be a perfect stranger to the science of these enlightened times, the heavens present a great and an elevating spectacle, the contemplation of which awakened the piety of the Psalmist”—a view in which Dr Whewell concurs. Sir David then comes to consider the doctrine of “Man, in his future state of existence, consisting, as at present, of a spiritual nature residing in a corporeal frame.” We must, therefore, find for the race of Adam, “if not for the races which preceded him!”[50]“a material home upon which he may reside, or from which he may travel to other localities in the universe.” That house, he says, cannot be the earth, for it will not be big enough—there will be such a “population as the habitable parts of our globe could not possibly accommodate;” wherefore, “we can scarcely doubtthat their future abode must be on some of the primary or secondary planets of the solar system, whose inhabitants have ceased to exist, like those on the earth; or on planets which have long been in a state of preparation, as our earth was, for the advent of intellectual life.” Here, then, is “the creed of the philosopher,” as well as “the hope of the Christian.” Passing, according to the order adopted in this paper, from the first chapter (“Religious Aspect of the Question”), we alight on the seventh, entitled “Religious Difficulties.” We entertain too much consideration for Sir David Brewster to speak harshly of anything falling from his pen; but we think ourselves justified in questioning whether this chapter—dealing with speculations of an awful nature, among which the greatest religious and philosophical intellects tremble as they “go sounding on their dim and perilous way”—shows him equal to cope with his experienced opponent, whom every page devoted to such topics shows to have fixed theDifficultywith which he proposed to deal, fully and steadily before his eyes, in all its moral, metaphysical, and philosophical bearings, and to have discussed it cautiously and reverently. We shall content ourselves with briefly indicating the course of observation on that “difficulty” adopted by Sir David Brewster, and leaving it to the discreet reader to form his own judgment whether Sir David has left the difficulty where he found it, or removed, lessened, or enhanced it.
Dr Whewell, in hisDialogue, thus temperately and effectively deals with this section of his opponent’s lucubrations:—
“His own solution of the question concerning the redemption of other worlds appears to be this, that the provision made for the redemption of man by what took place upon earth eighteen hundred years ago, may have extended its influence to other worlds.
“In reply to which astronomico-theological hypothesis three remarks offer themselves: In the first place, the hypothesis is entirely without warrant or countenance in the revelation from which all our knowledge of the scheme of redemption is derived; in the second place, the events which took place upon earth eighteen hundred years ago, were connected witha train of events in the history of man, which had begun at the creation of man, and extended through all the intervening ages; and the bearing of this whole series of events upon the condition of the inhabitants of other worlds must be so different from its bearing on the condition of man, that the hypothesis needs a dozen other auxiliary hypotheses to make it intelligible; and, in the third place, this hypothesis, making the earth, insignificant as it seems to be in the astronomical scheme, the centre of the theological scheme, ascribes to the earth a peculiar distinction, quite as much at variance with the analogies of the planets to one another, as the supposition that the earth alone is inhabited; to say nothing of the bearing of the critic’s hypothesis on the other systems that encircle other suns.”[51]
“In freely discussing the subject of a Plurality of Worlds,” says Sir David, “there can be no collision between Reason and Revelation.” He regrets the extravagant conclusion of some, that the inhabitants of all planets but our own, “are sinless and immortal beings that never broke the Divine Law, and enjoying that perfect felicity reserved for only a few of the less favoured occupants of earth. Thus chained to a planet, the lowest and most unfortunate in the universe, the philosopher, with all his analogies broken down, may justly renounce his faith in a Plurality of Worlds, and rejoice in the more limited but safer creed of the anti-Pluralist author, who makes the earth the only world in the universe, and the special object of God’s paternal care.”[52]He proceeds, in accordance with “men of lofty minds and undoubted piety,” to regard the existence of moral evil as a necessary part of the general scheme of the universe, and consequently affecting all its Rational Inhabitants.[53]He “rejects the idea that the inhabitants of the planets do not require a Saviour; and maintains the more rational opinion, that they stand in the same moral relation to their Maker as the inhabitants of the earth; and seeks for a solution of the difficulty—how can there be inhabitants in the planets, when God had but One Son, whom He could send to save them? If we can give a satisfactory answer to this question, it may destroy the objections of the Infidel, while it relieves the Christian from his difficulties.”[54]... “When our Saviour died, the influence of His death extended backward, in the Past, to millions who never heard His name; in the Future, to millions who never will hear it ... a Force which did not vary with any function of the distance.[55]... Emanating from themiddleplanet of the system.”
——Theearththemiddleplanet of the system? How is this? In an earlier portion of his book (p. 56), Sir David had demonstrated that “our earth is neither themiddle[his own italics] planet, nor the planetnearestthe sun, nor the planet furthest from that luminary: that therefore the earth, as a planet, has no pre-eminence in the solar system, to induce us to believe that it is the only inhabited world....Jupiteris themiddleplanet (p. 55), and is otherwise highly distinguished!” How is this? Can the two passages containing such direct contradictions have emanated from the samescientificcontroversialist?—To resume, however:
—“Emanating from the middle planet of the system, why may it not haveextended to them all, ... to the Planetary Races in the Past, and to the Planetary Races in the Future?... But to bring our argument more within the reach of an ordinary understanding”—he supposes our earth split into two parts! the old world and the new (as Biela’s comet is supposed to have been divided in 1846), at the beginning of the Christian era![56]—“would notboth fragmentshave shared in the beneficence of the Cross—the penitent on the shores of the Mississippi, as richly as the pilgrim on the banks of the Jordan?... Should this view prove unsatisfactory to the anxious inquirer, we may suggest another sentiment, even though we ourselves may not admit it into our creed.... May not the Divine Nature, which can neither suffer, nor die, and which, in our planet,onceonly clothed itself in humanity,resume elsewhere a physical form, and expiate the guilt of unnumbered worlds?”[57]
We repeat, that we abstain from offering any of the stern strictures which these passages almost extort from us.
He proceeds to declare himself incompetent to comprehend the Difficulty “put in a form so unintelligible” by the Essayist—that of a kind of existence, similar to that of men, in respect of their intellectual, moral, and spiritual character, and itsprogressivedevelopment, existing in any region occupied by other beings than man. He denies that Progression has been the character of the history of man,[58]but rather frequent and vast retrogressions ever since the Fall; and asks “which of these ever-changing conditions of humanity is theuniquecondition of the Essayist—incapable of repetition in the scheme of the Universe?”[59]Why may there not be an intermediate race between that of man and the angelic beings of Scripture, where human reason shall pass into the highest form of created mind, and human affections into their noblest development?—
“Why may not the intelligence of the spheres be ordained for the study of regions and objects unstudied and unknown on earth? Why may not labour have a better commission than to earn its bread by the sweat of its brow? Why may it not pluck its loaf from the bread-fruit tree, or gather its manna from the ground, or draw its wine from the bleeding vessels of the vine, orinhale its anodyne breath from the paradise gas of its atmosphere?”[60]
And Sir David thus concludes the chapter:—
“The difficulties we have been considering, in so far as they are of a religious character, have been very unwisely introduced into the question of a Plurality of Worlds. We are not entitled to remonstrate with the sceptic, but we venture to doubt the soundness of that philosopher’s judgment who thinks that the truths of natural religion are affected by a belief in planetary races, and the reality of that Christian’s faith who considers it to be endangered by a belief that there are other Worlds than his own.”
This last paragraph induces us to go so far as to doubt whether Sir David Brewster has addressed his understanding deliberately, to the subject to which so large a portion of the most elaborate reasonings of Dr Whewell have been directed.
Sir David does not quarrel with the Essayist’s account of the constitution of man; and we must now see how he deals with the Essayist’s arguments drawn from Geology.
Sir David “is not disposed to grudge the geologist even periods so marvellous” as “millions of years required for the formation of strata, provided they be considered as merely hypothetical;” and admits that “our seas and continents have nearly the same locality, and cover nearly the same area, as they did at the creation of Adam;” but demurs to the conclusion that the earth was prepared for man by causes operating so gradually as the diurnal change going on around us. “Why may not the Almighty have deposited the earth’s strata, during the whole period of its formation, by arapidprecipitation of their atoms from the waters which suspended them, so as to reduce the period of the earth’s formation to little more than the united generations of the different orders of plants and animals constituting its organic remains? Why not still further shorten the period, by supposing that plants and animals, requiring, in our day, a century for their development, may in primitive times have shot up in rank luxuriance, and been ready, in a fewdays!or months! or years, for the greatpurpose of exhibiting, by their geological distribution, the progressive formation of the earth?”[61]
These questions, of which a myriad similar ones might be asked by any one, we leave to our geological readers; and hasten to inform them, that in involuntary homage to the powerful reasonings of his opponent, Sir David Brewster is fain to question the “inference that man did not exist during the period of the earth’s formation;”[62]and to suggest that “there may have existed intellectual races in present unexplored continental localities, or the immense regions of the earth now under water!”—“The future of geology may be pregnant with startling discoveries of the remains of intellectual races, evenbeneaththe primitive Azoic[63]formations of the earth!... Who can tell what sleeps beyond? Another creation may be beneath! more glorious creatures may be entombed there! the mortal coils of beings more lovely, more pure, more divine than man, may yet read to us the unexpected lesson that we have not been the first, and may not be the last of the intellectual race!”[64]Is he who can entertain and publish conjectures like these, entitled to stigmatise so severely those of other speculators—as “inconceivable absurdities, which no sane mind can cherish—suppositions too ridiculous even for a writer of romance!” This wild license given to the fancy may not be amiss in a poet, whose privilege it is that his “eye in a fine phrenzy rolling” may “give to airy nothing a local habitation, and a name:”—but when set in the scale against the solemnly magnificent array of facts in the earth’s history established by Geology, may be summarily discarded by sober and grave inquirers.
The Essayist’s suggested analogy between man’s relation to time and to space appears to us not understood, in either its scope or nature, by Sir David Brewster. At this we are as much surprised, as at the roughness with which he characterises the argument, as “the most ingenious though shallow piece of sophistry he has ever encountered in modern dialectics.” The Essayist suggests a comparison between the numbers expressing the four magnitudes and distances,—of the earth, the solar system, the fixed stars, and the nebulæ—and the numbers expressing the antiquity of the four geological periods “for the sake of giving definiteness to our notions.” Sir David abstains from quoting these last expressions, and alleges that the Essayist, “quitting the ground of analogy,” founds an elaborate argument on the mutual relation of an atom of time and an atom of space. The “argument” Sir David thus presents to his readers, the capital and italic letters being his own: “That is,the earth, theATOM OF SPACE,is the only one of the planetary and sidereal worlds that is inhabited, because it was so long without inhabitants, and has been occupied only anATOM OF TIME.”[65]“If any of our readers,” he adds, “see the force of this argument, they must possess an acuteness of perception to which we lay no claim. To us, it is not only illogical; it is a mere sound in the ear, without any sense in the brain.” This is the language possibly befitting an irritated Professor towards an ignorant and conceited student, but hardly suitable when Sir David Brewster is speaking of such an antagonist as he cannot but know he has to deal with. It does not appear to us the Essayist’s attempt, or purpose, to establish any arbitrary absoluterelationbetween time and space, or definite proportions of either, as concurring or alternative elements for determining the probability of a plurality of worlds. But he says to the dogmatic astronomical objector to Christianity, Such arguments as you have hitherto derived fromyourconsideration ofSPACE,MULTITUDE, andMAGNITUDE, for the purpose of depressing man into a being beneath his Maker’s special notice, I encounter by arguments derived from recent disclosures concerning another condition of existence—DURATION, orTIME. Protesting that neither Time nor Space has any true connection with the subject, nevertheless I will turn your own weapons against yourself. My argument from Time shall at least neutralise yours from Space: mine shall involve the conditions of yours, fraught with their supposed irresistible force, and falsify them in fact, as forming premises whence may be deduced derogatory inferences concerning man. The Essayist’s ingenious and suggestive argument is intended not to prove an opinion, butto remove an objection; which, according to the profound thinker, Bishop Butler, is the proper office of analogy. It is asked, for instance,howcan you suppose that man, such as he is represented to be, occupies only an immeasurably minute fraction of existing matter? and it is answered, I find that man occupies only an immeasurably minute fraction of elapsed time: and this is, to me, an answer to the “How,” as concluding improbability.Howis balanced againstHow: Difficulty against difficulty: they neutralise each other, and leave the great question, the great reality, standing as it did before either was suggested, to be dealt with according to such evidence as God has vouchsafed us. We, therefore, do not see that the Essayist is driven to say, as Sir David Brewster alleges he is, either that because man has occupied only an atom of space, he must live only an atom of time on the earth;[66]or that because he has lived only an atom of time, he must occupy but an atom of space. In dismissing this leading portion of the Essayist’s reasonings, we shall say only that we consider it worthy of the attention of all persons occupied in speculations of this nature, as calculated to suggest trains of novel, profitable, and deeply interesting reflection.
Thus far the Essayist, as followed by his opponent, on the assumption that the other bodies of the universe are fitted, equally with the earth, to be the abodes of life.But are they?Here we are brought to the last stage of the Essayist’s speculations—What physicalEVIDENCEhave we that the other bodies of the Solar System, besides the Earth, the Fixed Stars, and the Nebulæ, are structures capable of supporting human life, of being inhabited by Rational and Moral Beings?
The great question, in its physical aspect, is now fully before us: Is there that analogy on which the pluralist relies?
For the existence of Life several conditions must concur; and any of these failing, life, so far as we know anything about it, is impossible. Not air, only, and moisture, but a certain temperature, neither too hot nor too cold, and a certain consistence, on which the living frame can rest. Without the other conditions, an atmosphere alone does not make life possible; still less, prove its existence. A globe of red-hot metal, or of solid ice, however well provided with an atmosphere, could not be inhabited, so far as we can conceive. The old maxim of the logicians is true: that it requiresallthe conditions to establish the affirmative, but that the negative of anyoneproves thenegative.
