9. Before I make any attempt to answer these questions, I must pursue the difficulty somewhat further, and look at it in other forms. As I have said, the history of Man has been, in certain nations, a history of intellectual progress, from the earliest times up to our own day. But intellectual progress has been, as I have also said, in a great measure confined to certain nations thus especially favored. The greater part of the earth's inhabitants have shared very scantily in that wealth of knowledge to which the brightest and happiest intellects among men have thus been led. But though the bulk of mankind have thus had little share in the grand treasures of science which are open to the race, their life has still been very different from that of other animals. Many nations, though they may not have been conspicuous in the history of intellectual progress, have yet not been without their place in progress of other kinds—in arts, in arms, and, above all, in morals—in the recognition of the distinction of right and wrong in human actions, and in the practical application of this distinction. Such a progress as this has been far more extensively aimed at, than a progress in abstract and general knowledge; and, we may venture to say, has been, in many nations and in a very great measure, really effected. No doubt the imperfection of this progress, and the constant recurrence of events which appear to counteract and reverse it, are so obvious and so common as to fill with grief and indignation the minds of those who regard such a progress as the great business of the human race; but yet still, looking at the whole history of the human race, the progress is visible; and even the grief and the indignation of which we have spoken are a part of its evidences. There has been, upon the whole, a moral government of the human race. The moral law, the distinction of right and wrong, has been established in every nation; and penalties have been established for wrong-doing. The notion of right and wrong has been extended, from mere outward acts, to the springs of action, to affection, desire, and will. The course of human affairs has generally been such, that the just, the truthful, the kind, the chaste, the orderly portion of mankind have been happier than the violent and wicked. External wrong has been commonly punished by the act of human society. Internal sins, impure and dishonest designs, falsehood, cruelty, have very often led to their own punishment, by their effect upon the guilty mind itself. We do not say that the moral government which has prevailed among men has been such, that we can consider it complete and final in its visible form. We see that the aspect of things is much the contrary; and we think we see reasons why it may be expected to be so. But still, there has existed upon earth a moral government of the human race, exercised, as we must needs hold, by the Creator of man; partly through the direct operation of man's faculties, affections, and emotions; and partly through the authorities which, in all ages and nations, the nature of man has led him to establish. Now this moral progress and moral government of the human race is one of the leading facts on which Natural Religion is founded. We are thus led to regard God as the Moral Governor of man; not only his Creator and Preserver, but his Lawgiver and his Judge. And the grounds on which we entertain this belief are peculiarly the human faculties of man, and their operation in history and in society. The belief is derived from the whole complex nature of man—the working of his Affections, Desires, Convictions, Reason, Conscience, and whatever else enters into the production of human action and its consequences. God is seen to be the Moral Governor of man by evidence which is especially derived from the character of Man, and which we could not attempt to apply to any other creature than man without making our words altogether unmeaning. But would it not be too bold an assumption to speak of the Conscience of an inhabitant of Jupiter? Would it not be a rash philosophy to assume the operation of Remorse or Self-approval on the planet, in order that we may extend to it the moral government of God? Except we can point out something more solid than this to reason from, on such subjects, there is no use in our attempting to reason at all. Our doctrines must be mere results of invention and imagination. Here then, again, we are brought to the conviction that God is, so far as we yet see, in an especial and peculiar manner, the Governor of the earth and of its human inhabitants, in such a way that the like government cannot be conceived to be extended to other planets, and other systems, without arbitrary and fanciful assumptions; assumptions either of unintelligible differences with incomprehensible results, or of beings in all respects human, inhabiting the most remote regions of the universe. And here, again, therefore, we are led to the same difficulty which we have already encountered: Can the earth, a small globe among so many millions, have been selected as the scene of this especially Divine Government?
10. That when we attempt to extend our sympathies to the inhabitants of other planets and other worlds, and to regard them as living, like us, under a moral government, we are driven to suppose them to be, in all essential respects, human beings like ourselves, we have proof, in all the attempts which have been made, with whatever license of hypothesis and fancy, to present to us descriptions and representations of the inhabitants of other parts of the universe. Such representations, though purposely made as unlike human beings as the imagination of man can frame them, still are merely combinations, slightly varied, of the elements of human being; and thus show us that not only our reason, but even our imagination, cannot conceive creatures subjected to the same government to which man is subjected, without conceiving them as being men of one kind or other. A mere animal life, with no interest but animal enjoyment, we may conceive as assuming forms different from those which appear in existing animal races; though even here, there are, as we shall hereafter attempt to show, certain general principles which run through all animal life. But when in addition to mere animal impulses, we assume or suppose moral and intellectual interests, we conceive them as the moral and intellectual interests of man. Truth and falsehood, right and wrong, law and transgression, happiness and misery, reward and punishment, are the necessary elements of all that can interest us—of all that we can call Government. To transfer these to Jupiter or to Sirius, is merely to imagine those bodies to be a sort of island of Formosa, or new Atlantis, or Utopia, or Platonic Polity, or something of the like kind. The boldest and most resolute attempts to devise some life different from human life, have not produced anything more different than romance-writers and political theorists have devised as a form of human life. And this being so, there is no more wisdom or philosophy in believing such assemblages of beings to exist in Jupiter or Sirius, without evidence, than in believing them to exist in the island of Formosa, with the like absence of evidence.
11. Any examination of what has been written on this subject would show that, in speculating about moral and intellectual beings in other regions of the universe, we merely make them to be men in another place. With regard to the plants and animals of other planets, fancy has freer play; but man cannot conceive any moral creature who is not man. Thus Fontenelle, in his Dialogues on the Plurality of Worlds, makes the inhabitants of Venus possess, in an exaggerated degree, the characteristics of the men of the warm climates of the earth. They are like the Moors of Grenada; or rather, the Moors of Grenada would be to them as cold as Greenlanders and Laplanders to us. And the inhabitants of Mercury have so much vivacity, that they would pass with us for insane. "Enfin c'est dans Mercure que sont les Petites-Maisons de l'Univers." The inhabitants of Jupiter and Saturn are immensely slow and phlegmatic. And though he and other writers attempt to make these inhabitants of remote regions in some respects superior to man, telling us that instead of only five senses, they may have six, or ten, or a hundred, still these are mere words which convey no meaning; and the great astronomer Bessel had reason to say, that those who imagined inhabitants in the Moon and Planets, supposed them, in spite of all their protestations, as like to men as one egg to another.3
12. But there is one step more, which we still have to make, in order to bring out this difficulty in its full force. As we have said, the moral law has been, to a certain extent, established, developed, and enforced among men. But, as I have also said, looking carefully at the law, and at the degree of man's obedience to it, and at the operation of the sanctions by which it is supported, we cannot help seeing, that man's knowledge of the law is imperfect, his conviction of its authority feeble, his transgressions habitual, their punishment and consequences obscure. When, therefore, we regard God, as the Lawgiver and Judge of man, it will not appear strange to us, that he should have taken some mode of promulgating his Law, and announcing his Judgments, in addition to that ordinary operation of the faculties of man, of which we have spoken. Revealed Religion teaches us that he has done so: that from the first placing of the race of man upon the earth, it was his purpose to do so: that by his dealing with the race of man in the earlier times, and at various intervals, he made preparation for the mission of a special Messenger, whom, in the fulness of time, he sent upon the earth in the form of a man; and who both taught men the Law of God in a purer and clearer form than any in which it had yet been given; and revealed His purpose, of rewards for obedience, and punishments for disobedience, to be executed in a state of being to which this human life is only an introduction; and established the means by which the spirit of man, when alienated from God by transgression, may be again reconciled to Him. The arrival of this especial Messenger of Holiness, Judgment, and Redemption, forms the great event in the history of the earth, considered in a religious view, as the abode of God's servants. It was attended with the sufferings and cruel death of the Divine Messenger thus sent; was preceded by prophetic announcements of his coming; and the history of the world, for the two thousand years that have since elapsed, has been in a great measure occupied with the consequences of that advent. Such a proceeding shows, of course, that God has an especial care for the race of man. The earth, thus selected as the theatre of such a scheme of Teaching and of Redemption, cannot, in the eyes of any one who accepts this Christian faith, be regarded as being on a level with any other domiciles. It is the Stage of the great Drama of God's Mercy and Man's Salvation; the Sanctuary of the Universe; the Holy Land of Creation; the Royal Abode, for a time at least, of the Eternal King. This being the character which has thus been conferred upon it, how can we assent to the assertions of Astronomers, when they tell us that it is only one among millions of similar habitations, not distinguishable from them, except that it is smaller than most of them that we can measure; confused and rude in its materials like them? Or if we believe the Astronomers, will not such a belief lead us to doubt the truth of the great scheme of Christianity, which thus makes the earth the scene of a special dispensation.
13. This is the form in which Chalmers has taken up the argument. This is the difficulty which he proposes to solve; or rather, (such being as I have said the mode in which he presents the subject,) the objection which he proposes to refute. It is the bearing of the Astronomical discoveries of modern times, not upon the doctrines of Natural Religion, but upon the scheme of Christianity, which he discusses. And the question which he supposes his opponent to propound, as an objection to the Christian scheme, is:—How is it consistent with the dignity, the impartiality, the comprehensiveness, the analogy of God's proceedings, that he should make so special and pre-eminent a provision for the salvation of the inhabitants of this Earth, where there are such myriads of other worlds, all of which may require the like provision, and all of which have an equal claim to their Creator's care?
14. The answer which Chalmers gives to this objection, is one drawn, in the first instance, from our ignorance. He urges that, when the objector asserts that other worlds may have the like need with our own, of a special provision for the rescue of their inhabitants from the consequences of the transgression of God's laws, he is really making an assertion without the slightest foundation. Not only does Science not give us any information on such subjects, but the whole spirit of the scientific procedure, which has led to the knowledge which we possess, concerning other planets and other systems, is utterly opposed to our making such assumptions, respecting other worlds, as the objection involves. Modern Science, in proportion as she is confident when she has good grounds of proof, however strange may be the doctrines proved, is not only diffident, but is utterly silent, and abstains even from guessing, when she has no grounds of proof. Chalmers takes Newton's reasoning, as offering a special example of this mixed temper, of courage in following the evidence, and temperance in not advancing when there is no evidence. He puts, in opposition to this, the example of the true philosophical temper,—a supposed rash theorist, who should make unwarranted suppositions and assumptions, concerning matters to which our scientific evidence does not reach;—the animals and plants, for instance, which are to be found in the planet Jupiter. No one, he says, would more utterly reject and condemn such speculations than Newton, who first rightly explained the motion of Jupiter and of his attendant satellites, about which Science can pronounce her truths. And thus, nothing can be more opposite to the real spirit of modern science, and astronomy in particular, than arguments, such as we have stated, professing to be drawn from science and from astronomy. Since we know nothing about the inhabitants of Jupiter, true science requires that we say and suppose nothing about them; still more requires that we should not, on the ground of assumptions made with regard to them, and other supposed groups of living creatures, reject a belief, founded on direct and positive proofs, such as is the belief in the truths of Natural and of Revealed Religion.
15. To this argument of Chalmers, we may not only give our full assent, but we may venture to suggest, in accordance with what we have already said, that the argument, when so put, is not stated in all its legitimate force. The assertion that the inhabitants of Jupiter have the same need as we have, of a special dispensation for their preservation from moral ruin, is not only as merely arbitrary an assumption, as any assertion could be, founded on a supposed knowledge of an analogy between the botany of Jupiter, and the botany of the earth; but it is a great deal more so. There may be circumstances which may afford some reason to believe that something of the nature of vegetables grows on the surface of Jupiter; for instance, if we find that he is a solid globe surrounded by an atmosphere, vapor, clouds, showers. But, as we have already said, there is an immeasurable distance between the existence of unprogressive tribes of organized creatures, plants, or even animals, and the existence of a progressive creature, which can pass through the conditions of receiving, discerning, disobeying, and obeying a moral law; which can be estranged from God, and then reconciled to him. To assume, without further proof, that there are, in Jupiter, creatures of such a nature that these descriptions apply to them, is a far bolder and more unphilosophical assumption, than any that the objector could make concerning the botany of Jupiter; and therefore, the objection thus supposed to be drawn from our supposed knowledge, is very properly answered by an appeal to our really utter ignorance, as to the points on which the argument rests.
16. This appeal to our ignorance is the main feature in Chalmers' reasonings, so far as the argument on the one side or the other has reference to science. Chalmers, indeed, pursues the argument into other fields of speculation. He urges, that not only we have no right to assume that other worlds require a redemption of the same kind as that provided for man, but that the very reverse maybe the case. Man maybe the only transgressor; and this, the only world that needed so great a provision for its salvation. We read in Scripture, expressions which imply that other beings, besides man, take an interest in the salvation of man. May not this be true of the inhabitants of other worlds, if such inhabitants there be? These speculations he pursues to a considerable length, with great richness of imagination, and great eloquence. But the suppositions on which they proceed are too loosely connected with the results of science, to make it safe for us to dwell upon them here.
17. I conceive, as I have said, that the argument with which Chalmers thus deals admits of answers, also drawn from modern science, which to many persons will seem more complete than that which is thus drawn from our ignorance. But before I proceed to bring forward these answers, which will require several steps of explanation, I have one or two remarks still to make.
18. Undoubtedly they who believe firmly both that the earth has been the scene of a Divine Plan for the benefit of man, and also that other bodies in the universe are inhabited by creatures who may have an interest in such a Plan, are naturally led to conjectures and imaginations as to the nature and extent of that interest. The religious poet, in his Night Thoughts, interrogates the inhabitants of a distant star, whether their race too has, in its history, events resembling the fall of man, and the redemption of man.
Enjoy your happy realms their golden age?
And had your Eden an abstemious Eve?
Or, if your mother fell are you redeemed?
And if redeemed, is your Redeemer scorned?
And such imaginations may be readily allowed to the preacher or the poet, to be employed in order to impress upon man the conviction of his privileges, his thanklessness, his inconsistency, and the like. But every form in which such reflections can be put shows how intimately they depend upon the nature and history of man. And when such reflections are made the source of difficulty or objection in the way of religious thought, and when these difficulties and objections are represented as derived from astronomical discoveries, it cannot be superfluous to inquire whether astronomy has really discovered any ground for such objections. To some persons it may be more grateful to remedy one assumption by another: the assumption of moral agents in other worlds, by the assumption of some operation of the Divine Plan in other worlds. But since many persons find great difficulty in conceiving such an operation of the Divine Plan in a satisfactory way; and many persons also think that to make such unauthorized and fanciful assumptions with regard to the Divine Plans for the government of God's creatures is a violation of the humility, submission of mind, and spirit of reverence which religion requires; it may be useful if we can show that such assumptions, with regard to the Divine Plans, are called forth by assumptions equally gratuitous on the other side: that Astronomy no more reveals to us extra-terrestrial moral agents, than Religion reveals to us extra-terrestrial Plans of Divine government. Chalmers has spoken of the rashness of making assumptions on such subjects without proof; leaving it however, to be supposed, that though astronomy does not supply proof of intelligent inhabitants of other parts of the universe, she yet does offer strong analogies in favor of such an opinion. But such a procedure is more than rash: when astronomical doctrines are presented in the form in which they have been already laid before the reader, which is the ordinary and popular mode of apprehending them, the analogies in favor of "other worlds," are (to say the least) greatly exaggerated. And by taking into account what astronomy really teaches us, and what we learn also from other sciences, I shall attempt to reduce such "analogies" to their true value.
14. The privileges of man, which make the difficulty in assigning him his place in the vast scheme of the Universe, we have described as consisting in his being an intellectual, moral, and religious creature. Perhaps the privileges implied in the last term, and their place in our argument, may justify a word more of explanation. Religion teaches us that there is opened to man, not only a prospect of a life in the presence of God, after this mortal life, but also the possibility and the duty of spending this life as in the presence of God. This is properly the highest result and manifestation of the effect of Religion upon man. Precisely because it is this, it is difficult to speak of this effect without seeming to use the language of enthusiasm; and yet again, precisely because it is so, our argument would be incomplete without a reference to it. There is for man, a possibility and a duty of bringing his thoughts, purposes, and affections more and more into continual unison with the will of God. This, even Natural Religion taught men, was the highest point at which man could aim; and Revealed Religion has still more clearly enjoined the duty of aiming at such a condition. The means of a progress towards such a state belong to the Religion of the heart and mind. They include a constant purification and elevation of the thoughts, affections, and will, wrought by habits of religious reflection and meditation, of prayer and gratitude to God. Without entering into further explanation, all religious persons will agree that such a progress is, under happy influences, possible for man, and is the highest condition to which he can attain in this life. Whatever names may have been applied at different times to the steps of such a progress;—the cultivation of the divine nature in us; resignation; devotion; holiness; union with God; living in God, and with God in us;—religious persons will not doubt that there is a reality of internal state corresponding to these expressions; and that, to be capable of elevation into the condition which these expressions indicate, is one of the especial privileges of man. Man's soul, considered especially as the subject of God's government, is often called his Spirit; and that man is capable of such conformity to the will of God, and approximation to Him, is sometimes expressed by speaking of him as a spiritual creature. And though the privilege of being, or of being capable of becoming, in this sense, a spiritual creature, is a part of man's religious privileges; we may sometimes be allowed to use this additional expression, in order to remind the reader, how great those religious privileges are, and how close is the relation between man and God, which they imply.
15. We have given a view of the peculiar character of man's condition, which seem to claim for him a nature and place unique and incapable of repetition, in the scheme of the universe; and to this view astronomy, exhibiting to us the habitation of man as only one among many similar abodes, offers an objection. We are, therefore, now called upon, I conceive, to proceed to exhibit the answer which a somewhat different view of modern science suggests to this difficulty or objection.
For this purpose, we must begin by regarding the Earth in another point of view, different from that hitherto considered by us.
