In preparing them for the press I have preserved as much as possible their original form, because I am desirous that they should appear what they are — Papers read before a limited audience, members of a Society formed for the encouragement and prosecution of scientific investigation, and familiar to some extent with the topics discnssed and the prin- ciples attempted to be established. Begarded in any other light, these Papers would scarcely be suited for publication ; if for no other reason, because of their incompleteness. They do not pretend to exhaust the subjects upon which they treat, even under the aspects iij which they are presented, but only to suggest and de- velop certain lines of thought, and the conclusions to which these seem to lead, so far as they appeared to fall within the objects of the Society. The second and third Papers, " Law in Creation" and " Law in History," ai-e printed almost as they were read ; though in the latter I should have liked to develop more fully the last section — that which relates to the influence of former civilizations upon modern thought. I found, however, that this could not be done at all ade- quately without an amount of additional matter which I did not feel justified in inserting. I have, therefore, left it in its original state. In the first Paper I have added one or two paragraphs in order to elucidate more fully the sense in which the term " law" is used in scientific discussions, and the ambiguities which arise from the other senses in which the word is habitually employed. And in the last Paper I have expanded the earKer portion for the purpose of exhibiting more completely what appears to me to be the essential independence of science and theology, as well as the reasons for considering such a discussion not merely legitimate but even necessary. The latter part, however, remains almost verbally as it was originally written. It may be thought, as was suggested by one of the members of the Society, that the views I have endeavoured to establish involve the impossibility of miracles. This, however, appears to me to be a misconception ; and certainly I do not hold such an opinion. I conceive, undoubtedly, that nature ddes not and cannot witness to any supernatural interposition ; and further, that the prevalence of law which wfe trace wherever our investigations extend furnishes a, strong presumption against the occurrence of any such interposition. But this, I imagine, would be conceded by the most unhesitating asserter of miracles. It is indeed the impossibility of accoimting for an occurrence on natural grounds, and its intrinsic improbability as a fact, which gives to it its evidential character and value as a miracle. If we could in any manner explain it, or show that its occur- rence was naturally to be looked for, it would to that extent become worthless as a symbol of divinity or an attestation of doctrine. But I do not, therefore, conclude that miracles cannot have occurred, or even that there may not be considerations resting upon other than natural grounds which may diminish the intrinsic improbability of their occurrence. I do not doubt the power of God to work miracles, and certainly I do not assume that I am able to decide whether he will or wiU not exercise that power. It seems, however, to me, that in any enquiries upon the subject the question whether or not the alleged phenomena were manifested is a question of evi- dence — whether or not they were miraculous is a question of faith ; and therefore that miracles as such are beyond the scope of science. I imagined, therefore, that any discussion of the subject would not fall within the limits of the enquiries in which I was engaged ; but I have thought it right to guard myself from being supposed on that accoimt to deny the possibility or the actual occurrence of miracles. These Papers have no pretensions to originality. Although I should have some difficulty in referring the various arguments and illustrations to the sources from which they were taken, it is pro- bable that all have been suggested in the course of reading ; and ■with regard to the greater portion, they would be found in works readily accessible to most of my hearers. Still I have not im- plicitly followed any authority. I have stated my own conclusions in my own language ; hut the grounds of my conclusions have not been the result of original investigation. My object, however, in these Papers has been not to discover new facts, but to show the principles which we are to apply in drawing conclusions from facts already known. It only remains to add that, as I understand it, the printing of these Papers by the Adelaide Philosophical Society does not imply any agreement with the particular views I have pronounced. It is, I believe, nothing more than an acknowledgment that the im- portance and interest of the questions discussed, and, to a certain extent also, the manner in which they have been treated, justify the Society in securing for the members a more permanent and available record than would otherwise exist. Adelaide, June 24, 1864. EEEATUM. Page 26, third line from tlic bottom, between "otherwise" and "is,"' insert 'is supernatural." THE IDEA OF LAW IN NATURE. I PROPOSE in the course of the present, and of two or three Bucceeding papers, to offer a few observations for the purpose of explaining and illustrating the operation of law in nature, and of discussing how far it may be traced in what we know or can infer with regard to the plan of nature and the history of mankind ; as ■well as the relation which these subjects, and science in general, bear to theology. The present paper is chiefly introductory, and its object is to illustrate what, in default of a more appropriate term, I have designated " The Idea op Law in Natttee." The first impression produced by the aspect of external nature is, that almost everything is capricious and irregular. With the single exception of the succession of day and night, and the position and courses of the heavenly bodies, there is nothing that, to the unin- structed eye, bears the impress of order or method. The wind bloweth where it listeth — the clouds arise and the rains descend — seasons of drought and of flood succeed or alternate with each other — ^hurricanes and calms, sunshine and storms, come and go fitfully and irregularly, according to no assignable or intelligible order. And these events are not merely irregular, but they seem also to be isolated. There are between them no signs of mutual inter- dependence; and even when experience has shown that there is practically a connection between two events, this connection is often, so far as appears, altogether arbitrary ; there may be a connec- tion in fact, but there is none in reason. And all this is the case even more emphatically with the phenomena of life and organi- zation; while these latter have further a mystery of their own. Generation, nutrition^ growth, and decay — ^birth, life, and death — are still among the imsolved problems of science ; and it is no marvel, therefore, that they should, to the earliest thinkers, have ap- peared not only to be beyond their powers of investigation, but to belong to quite a difierent order of phenomena from those of inor- ganic matter. The first rude division of objects, therefore, would be into those which possessed and those which were destitute of life : the former being supposed to be endued with an animating spirit, which would account for all the appearances which they presented — the latter having no internal power, but their opera- tions being caused by the active energy of some Divine agency external to themselves. It is not necessary now to attempt to trace the steps by which this primitive conception has been gradually changed into that with which we are now familiar. It has been argued by Comte, in his Philosophie Positive, that the human intellect in every science has passed, or is passing, through three stages, which he designates as the theological (or supernatural), the metaphysical, and the posi- tive. " In the first (the supernatural) phase the mind seeks causes ; it aspires to know the essences of things, and the absolute reason of their operation. It regards all effeets as the production of super- natural agents. Unusual phenomena are regarded as the signs of the pleasure or displeasure of some god. In the metaphysical stage a modification takes place : the supernatural agents are set aside for abstract forces or entities supposed to inhere in various substances, and capable of producing the appearances which they manifest. In the positive phase, the mind, convinced of the futility of all enquiries into causes and essences, restricts itself to the obser- vation and classification of phenomena, and to the discovery of the invariable relations of succession and similitude which things bear to each other ; in a word, to the discovery of the laws of pheno- mena." There can be no doubt, I ime^ine, that this conception truly represents one aspect of the progress of the human mind ; and it is not necessary to go to the past for illustration of these different methods of viewing the same actual fact: since not merely at the present time are there some sciences — sociology for instance — which are, so far as the great majority of thinkers are concerned, stiU in the supernatural stoige ; and others, such as biology, in the metaphysical ; but if we extend our survey beyond a comparatively narrow circle, we shall find that the vast majority of the human race are still in one or other of the preliminaly stages in regard to every class of phenoiriena. The idea that pestilence is the result, not of the neglect of sanitary laws, but of the Divine displeasure, and is to be averted or removed by propitiatory rites, is as familiar to the modern as it was to the ancient mind, and to civilized as to un- civilized communities. In fact, with the greater part of mankind, every unfamiliar occurrence, especially if its results are widely injurious, is at once imagined to be supernatural ; and as the method of education in every country is still theological instead of scientific, it can be no matter of surprise that this should be the case. The positive conception, so far as it is realized, can only be attained in after life by the process of discarding the lessons which the mind has first been taught ; and this is beyoad the power of the many. It should, however, be observed that the conception of the positive philosopher, that is to say, of the enquirer who seeks exclusively to ascertain the laws which regulate the relations of phenomena, does not necessarily contradict either the theological or the metaphysical notion. It does not pretend to investigate the ab- solute cause of anything ; it confesses that any such enquiry is beyond its province, and that it has neither methods nor instruments of investigation applicable to the purpose. All that it can perceive is certain appearances ; all that it can discover is in what relation of coincidence or succession these appearances stand to each other. These relations it abstracts and generalizes, and the results are the laws which it seeks to trace and define. What imderlies these appearances — what gives efficiency to these laws — what is the ultimate principle or the efficient cause of phenomena — as it cannot discover it is content to be ignorant of; but it asserts that, ^ whatever this unlcnown something may be, it always operates in- variably, the same antecedents producing the same results, and every change in the antecedent being accompanied by a corres- ponding change in the result. And in confirmation of this sbssertion it appeals to its power, in proportion as these laws are understood, to predict or to produce results. It assumes, moreover, as a necessary hypothesis, that all phenomena have analogous relations which are capable of being ultimately ascertained by the application of appropriate methods of investigation. This, however, does not exclude the supernatural conception, excepting upon the hypothesis that a supernatural cause must necessarily be capricious and irre- gular — a hypothesis for which few would now care to contend. The idea, then, of Law in Nature implies that certain definite and constant relations subsist between all classes of phenomena — that there is nothing isolated and nothing anomalous — that any apparent irregularities are only seeming, and relative to our ignorance ; and that, although it may well happen, either owing to the complexity of the phenomena, or to their unusual character, that certain classes of facts may be, for an indefinite period or for ever, beyond the po ler of the scientific method, yet that this would be simply because of the limitation of our faculties, and not because these facts are really of a different order. Whatever may be the truth or error of this idea, there can be no doubt that it is only in so far as it is capable of realization that there can be any science. If there be any classes of facts, or any single facts, which stand isolated and apart from the general scheme of nature — ^not being, if I may so express myself, links in the chain of causation — they are by that very isolation rendered incapable of being the subjects of scientific investigation. The essential object ef science — that without which it has no meaning and no value — is to ascertain those very relations of cause and effect which, by supposition, these facts do not possess. They are pheno- mena which we may observe and register, and upon which we may speculate, but we can assign them no place in the order of nature. Science implies prevision ; its formula is — given certain conditions and arrangements, and certain results follow as the invariable effect — but with regard to these assumed facts no prevision is possible. Take, for instance, as illustration, acts which depend upon human volition. It is well known that there are two classes of thinkers upon this subject, the one of which asserts and the other denies the absolute freedom of the will in man. Into this controversy I have no intention to enter ; in part it is a more question of words, there being no difference of opinion as to the actual phenomena, but only as to the phrases in which they should be described ; and in part it is bound up with questions which science, as I understand it, does not profess to be able to solve. But it is obvious that, on the hypothesis of the absolute freedom of the will, in the sense for which one class contends, it is impossible to make the acts which freely result from the will the subject of calculation. We may guess, but we cannot with any consistency venture to predict; since although these acts, when performed, become themselves causes, and in their operation differ in no wise from similar acts produced by known and calculable laws, yet the volition of which they are the result, being self-determined, is therefore beyond law. And under whatever modifications the idea of the freedom of the will may be entertained, it must necessarily be the case that, in so far as it is free and self- determined, its acts are incapable of prediction; and this, not be- cause of the complexity of tbe phenomena, or of our ignorance of some of the conditions of the problem, but because this element of self-determination is on that very account beyond the reach of the method of scientific investigation. I have instanced this merely as an illustration of the necessary limits of science ; which can only be concerned with phenomena which are themselves determined by their antecedents, and can therefore, to the extent of our know- ledge and faculty, be predicted. But I may go on to remark that, in reality, this question of the freedom of the will is one which, in its scientific aspect at least, is speculative rather than practical. In our personal and individual experience we always find our know- ledge of men's character and circumstances sufficient to enable us so far to foresee their conduct in the ordinary transactions of life, as to form a safe guide to ourselves ; and in public affairs, though prediction is more difficult as to the particular dii-ection which the popular feeling may take, or the extent to which it may be embodied in action, yet on looking back we are for the most part able to trace clearly the nature and the mode of operation of the causes which have led to any great national movement, and thus to gather rules for future guidance. More than this, it is not pro- bable we shall ever be able to do, since the most unbending advocate of the doctrine of necessity can never expect that he will be able to bring under any mathematical formula all the various causes which contribute to determine the will of an individual or the collective wiU of a people ; and less than this no rational observer of himself and others can be satisfied to claim. And this being the case, I confess that it appears to me to be altogether imma- terial, for the purposes of science, whether we employ the word freedom or the word necessity. If the word necessity is used, its conception must be enlarged so as to admit the well-nigh infinite variety and play of motive and of feeling which go to make up the individual man ; and if the word freedom be used, it must be so understood as to allow that, in fact, the acts of all men are capable of being predicted just in proportion as we understand their character and the circumstances in which they will be placed. No doubt it is the case, that when the particular term, freedom or necessity, is abstracted from the phenomena which it represents, and then made the basis of a train of deductive reasoning, founded upon the meaning of the term, and not upon those phenomena, very different results will be arrived at, according to which of the two terms is employed. This, however, is only a particular instance of a very general source of error — reasoning upon the symbol in forgetfolness of the things symbolized — an error which none can wholly escape in cases where the symbols \ised have any meaning of their own, and which is prevalent in proportion to the force and vitality of the expressions employed. And as we probably never shall, and certainly need not wish to, come down to abstract signs — ^to the a and b and x and y of the algebraist — ^we must be content to remain liable to this error, only endeavoiu-irg, by a constant remembrance of the liability, to escape, as far as possible, its actual commission. This is perhaps a digression, but it is so nearly connected with the topic of this paper, and appears to me so to illustrate some of the aspects of the question, that I trust it may be pardoned. Now, this being the idea of law in nature as a subject of science, and this its ideal limitation, the question arises, is there such a limitation in fact ? Are there any phenomena in nature which are really without a natural cause ? Before attempting to give any answer to this question, it is right that I should explain the sense in which 1 employ the word cause. I have said that with absolute, or what has been termed efficient causation, science properly so called has nothing to do ; but we are nevertheless compelled to use a word which in the general mind connotes these ideas. But I use the word here to express the sum of the conditions which determine any particular phenomenon. These conditions may precede or be co- incident with the phenomenon, or, as is very frequently the case, they partly precede and partly coincide with its manifestations, so that the word antecedents is in many cases inapplicable. To state the question, then, in somewhat different language, but expressing the same meaning — are there any phenomena in nature which are not determined by certain known or knowable conditions ? In the first place it would seem certain that aU phenomena, however exceptional their origin may be supposed to be, do, in reality, so soon as they are manifested, take their place in nature, and at once become part of the network of causation. It would seem, therefore, to be improbable that they did not originate in accordance with the laws which, when once manifested, they obey and harmonize with. To take, for instance, the origin of a new species. However originatiag, the individuals of which it is com- posed are, from the very instant of its existence, subject to all the natural laws, material and vital. They are nourished in the same manner ; their frame is composed of the same constituents ; they are affected by the same influences and in the same degree; they propa- gate their like, and they die, in preciselj- the same manner aa those whose origin is confessedly owing to natural laws. If the first in- dividual or pair of a species differed in any assignable character from their successors, if they were differently affected by all or by any natural laws, there would be a ground in reason for assigning to them a different origin ; but the very idea of a species according to the definition of those who argue for its supernatural origin excludes any such difference, since it implies that the parents beget offspring which in all essentials and in all specific distinctions resemble themselves. To infer, therefore, a supernatural cause for what, tried by any test we can apply, appear to be natural effects, would seem in reality to be only a confession of ignorance ; at any rate there is nothing in the observed phenomena to warrant any such inference. All that we see, all of which we can find the trace, tells the same tale. The phenomena of ora;anization and Hfe manifest themselves in orderly development and succession according to definite laws, and nothing affords the faintest indication of that period of disorder and disorganization which some persons, it may be surmised more devout than intelligent, have assumed as the necessary proof of the existence of the Supreme Being. — And, in the second place, it is obvious that if there are such, it is to us, not merely as men of science but as men of action — men whose business in this world is emphatically to do, whatever other business we may have — just the same as though there were not. I have said that if there are such they are beyond the domain of science — they can neither be foreseen nor accounted for — no precautions on our part can avoid — no power can produce them. Hence we must leave them out of consideration. In fact, the dilemma appears to me to be inevitable : either events occur according to some law, in which case we may, in proportion to our knowledge and power, so conform our conduct to the reqtiirements of that law as to enable us to pro- cure the advantages which it offers and to escape the evils which it threatens ; or we must leave them out of our consideration altogether, excepting in so far as it may be within the scope of our abUity to provide against the inconvenience which their occurrence, whenever it does take place, may occasion. If we cannot tell whether an event will happen or not, or whether there is any assignable probability that it will happen : and if its happening or the reverse can neither be averted or procured by any act of ours, then we may indeed attempt to provide against any consequences which in the natural course of things may follow from its happening ; but otherwise we must arrange our plan of life and form our theories of nature without reference to it. Our practical position in this respect would be, for all time, analogous to that of those who, in the existing stats of knowledge, live in the neighbourhood of a volcano. They may know that at any moment an eruption may occur which wiU destroy all the fruits of their labours and perhaps their lives ; but they cannot prevent it — they cannot tell how soon or how long deferred its coming may be, or whether, if it does come, they or others will be the sufferers. Hence they go on sowing and reaping, planting and pruning, and gathering in the vintage, buUding houses and bams, marrying and giving in marriage, just as though no erup- tions were to be feared. They may take precautions against any of the preventible evils which may be produced by the eruption, but otherwise they live and act as those do who are exposed to no such dangers. Undoubtedly the idea of the imminence of such an event, or of any event which can neither be foreseen nor averted, would have an inevitable tendency, in so far as it was realized, to paralyze effort, and to destroy that feeling of security which is the encourage- ment of exertion and the best earnest of success. Happily, how- ever, the classes of phenomena which can now be regarded as thus anomalous are few, and they are daily being brought nearer even in common apprehension to the same conception which we apply to ordinary events. There is, however, an ambiguity in the employment of the term law in reference to this subject which it is important always to bear in mind, and which it will be weU to elucidate. The word law in fact is in itself misleading, since its primary, or at at any rate its ordinary use implies something external to the phenomena which are to be regulated by it. The term law, however, as applied to designate what are called laws of nature, is only an explicit statement of the observed uniformity of relations existing among the phenomena themselves, and resulting, so far as we can observe, from the very nature of the phenomena. Certain uniformities of coincidence or succession are observed, which are summed up in one general expression, and this general expression is termed the law of the phenomena. Thus, that all unsupported bodies fall to the ground, is a law ; but it is obvious that this does not imply any force external to the phenomena, by which this result is caused ; it is merely the statement in one formula of the observed phenomena. So long as it remains, however, in this first stage, it is a mere empirical law. When, however, we go a step farther and say that all unsupported bodies fall to the ground because they are attracted by the earth, and that they are attracted by the earth because all bodies attract each other in proportion to their mass, this first law ceases to be empirical, be- cause we are able to deduce it from some mere geoeral law ; but then the latter law, of which the particular law is the consequence, must, I imagine, be called an empirical law, unless we can show that it is the consequence of some law yet more general. But how- ever wide may be our generalization, and however many particular uniformities may be included in one general expression, still each particular law, as well as the general law in which they are all included, is only an expression or formula which describes the actual observed relation subsisting between the phenomena which it embraces. It thence follows that to talk of a violation of a law of nature, or an exception to it, is something like a contradiction in terms. Since the law, or what we term by that name, is nothing more thau a general expression of the observed relation, if anything occurs which is really an exception to that expression, it only shows that the expression does not truly represent the actual facts, and requires to be corrected. Thus, to take an illustration which has been used by Professor Kingsley — suppose it to be stated as a law that all heavy bodies fall to the ground ; but it is found that I or any one can catch a stone as it falls and prevent it from reaching the ground : it is clear that this proves, not that a law of nature is violated, but that we had not accurately expressed the actual relations of the phenomena, since our formula did not include the cases in which the tendency to fall to the ground was counteracted. We have only . then to correct our formula by stating it, that all bodies, unless supported, will fall to the ground, or that all bodies have a tendency to fall to the ground, and there is no exception. It is, however, in moral relations that the ambiguity is most apparent. There are then, in fact, three senses in which the word is used — the scientific sense, as explained above ; the sense of a law imposed by some external authority ; and the sense of the rules which we deduce from the observed uniformities of nature as guides to our own conduct. And as the same word is used to express all of these diiferent conceptions, it constantly happens that the con- clusions which are proper to the one sense are erroneously trans- ferred to another. Thus, I have seen it argued by an eminent modern professor, " As for laws which work of themselves by an irresistible movement, how can we discover such in a past in which every law which we know has been outraged again and again ?" In the first place, it appears to me that the phrase " laws which work of themselves," whether by an irresistible movement or not, does not w express what is contended for by those who seek to discover a law in events. At any rate, it does not express my conception of the subject. I see certain f6rces in inorganic and in organic natnre, and I see that these operate with a certain uniformity which admits of their modes of operation being combined into general expres- sions. These general expressions, in accordance with ordinary usage, I call laws. But I attribute no inherent or intrinsic power, nor even any independent existence, to these laws. When I say that the attraction of two bodies to each other is directly as the mass and inversely as the square of the distance, I express a law of nature ; but that law is not the impelling or controlling force ; it is merely an expression of the mode and condition of action of the force. And the same is the case with regard to moral or mental laws, though, from the ambiguities of language, it is less clearly perceived. When I say that interest is one of the motives by which men are influenced, I state what is assumed to be a law of nature ; but then this law, so far as it is such, is only an expression of one manner in which the sum of the forces which exist in and constitute a human being do actually operate. A law, therefore, in this sense, is not a force ; it is not self-acting, nor does it con- stitute or confer an impulse ; it is simply the general expression which describes the manner in which a given force acts. It is, however, true that a law of nature as generally stated im- plies the'cxistence of the- force, the mode of whose action it defines. But though it implies rhe fact that such a force exists, it does not express anything as to its nature, excepting in so far as that nature is implied in or may be conjectured from the mode of its operation. The scientific expression, therefore, would be, not " laws which work of themselves," but that all forces work according to some ascertainable method, which method we call the law of the force, and which we include in the term " laws of nature." But again, when it is said " Every law which we know has been violated over and over again," it is obvious that the sense in which the term law had been used in the former part of the sentence is shifted in the latter, and it is used either in the sense of rules which men frame for themselves, or of the law which God has revealed.* Un- questionably every rule of morahty or prudence, whether deduced by the human reason or taught by divine revelation, has been "out- raged again and again ;" but the laws of nature, meaning by that * Tliis will be clear ty just supplying the definition in each case. "As for laws" (uniformities of relation) " which work of themselves by an irresistible movement, how are we to discover such, in a past in which every law" (rule of action either commanded by God or deduced by reason) " which we Isnow has been outraged again and again ?" 11 the actual relation between phenomena ; the manner in which the human will as a determinino; force manifests itself in the various circumstances of country, race, climate, government, religion; and the relations between the acts which the human will originates, and their consequences, have never been interrupted : since all these alleged violations of moral or prudential rules — all from which they result and all that they produce — are in reality just the very facts whose relations of sequence or coincidence we have to comprehend in certain general expressions, which expressions, when accurately deduced, will be the law. Thus, the kings of Egypt, in employing the labour of tens of thousands of men for generations in building the' Pyramids — Solomon, in expending a sum slightly exceeding the national debt of England in erecting and decorating the Temple of Jerusalem — the kings of Babylon, in depeopling provinces to fiU. the new capital which they had built — in a sense violated the laws of political economy. So, in the same sense, the vast majority of wars are violations of the laws of justice and humanity, and all vices violate the laws of morality, and most of them the laws of prudence — that is to say, they violate the rules of practice which we should deduce for the guidance of human conduct from our experience of the result of certain courses of action. And yet in reality none of these laws are broken; because, being only expressions of the re- lations of phenomena, they do, so far as they truly express those relations, manifest themselves as clearly in these alleged violations as they do when they are most carefully observed. For, in fact, the law is not that such and such things will or must be done, but that whatever things may be done such and such results follow from their doing. And these results inevitably follow, in so far as we have accurately expressed the law. And beside this every one of these acts was itself the result of forces acting in a determinate order. The conduct of the monarch or of the nation, or, perhaps more ac- curately, the combined action of the two, resulted from individual character and surrounding circumstances and influences. However little we may be able to indulge the expectation of determining the character or the law of these forces, it can hardly be suggested, since men were the instruments, that there is any other possible cause than individual character, and the circumstances of whatever kind external to the individual by which that character is made to embody itself in action. It is only necessary to add to this, that every law truly stated implies only a tendency, which will be eflFectual if not counteracted, but which is liable to counteraction by other forces operating in a 12 different direction. The forms in wliicli the forces of nature mani- fest themselves are innumerable, though it may be that the ultimate force is one; and every form implies a separate mode of action. The first laws are those which express these ■ modes of action by them- selves, making abstraction of everything else ; but these laws, though accurate in so far as they express tendencies, are probably never absolutely realized in practice : since, although the law for every form of force holds good for that so long as it operates by itself the conjoint action of two or more forms of force is the result not of the law of action of any one, but of the conjoint effect of the laws of action of all. It follows from this that the idea of law in nature implies that all the forces of nature work according to determinate laws — not by any means that there is symmetry, or what we might conceive of as order, in the results. A tree may grow irregularly ; different trees of the same species, planted at the same time, may grow taller or more spreading, feebly or vigorously, according to the soil, shelter, aspect, and other conditions of the place in which they were planted. But the processes of assimilation — the attraction of carbon from the atmosphere, and the exhalation of oxygen ; the forces of gravi- tation, of capillary attraction, and the rest ; all of these operate ac- cording to fixed and invariable laws. The effects which the conjoint operation of these forces may produce will be modified by the favouring or counteracting influences of other forces to which the plant is exposed ; but all the forces — those which result from, or which produce organization, as well as those which act externally to the organization, operate in a definite method, and with unvarying regularity. Always, for instance, when a piece of carbonate of lime is exposed to a certain heat in contact with air containing oxygen, will a portion of the carbon leave the lime to unite with a portion of the oxygen ; always will the various elementary bodies combine chemically in certain definite proportions, and in no other ; alwavs does living organized matter assimilate, either directly or indirectly, inorganic substances, forming out of them the same ternary or quater- nary compounds which go to build up the fabric of the plant or the animal ; always, that is, do the forces of nature act in exact conformity with the laws which the Author of nature has imposed. It is, in fact, as inconceivable, in the absence of a disturbing cause, that two bodies oppositely electrified should not attract each other when brought into the requisite proximity, or that the opposite poles of a magnet should not attract, and the corresponding poles repel, each other, as that the three angles of a triangle should be 13 equal to more or less than two right angles, or that two and two should not make four. And although some very ingenious gentlemen, two at the least, have lately been endeavouring to convince the world that upon a sufficient amount of evidence we might believe that two and two did make five, and by inference therefore that we might believe all the other impossibilities which I have in. stanced ; yet there is, I imagine, no danger of such a speculation ever taking the form of practice. When it does it will be a for- tunate day for those who have to pay, and an unlucky one for those who receive. If then we are justified in the assumption that the forces of na- ture — if in truth there is more than one force, of which heat, elec- tricity, gravitation, and the rest are specific manifestations — work according to fixed laws, it is a necessary inference from this that they have so worked in all time. We cannot upon any ground, scientific or otherwise, assume that there was a time when these forces did not exist wherever matter or life existed, or that they acted in any other manner or according to any other laws than those by which they are now regulated. And so far as an inference of this kind is susceptible of proof, we have proof of it in the disclosures of geology. In the records of the rocks we see the same results of mechanical and chemical laws — the same type of organization showing that the external nature to which that type was adapted was essentially the same as at present. The structure of the eye, for iastauce, shows that the laws of light were similar ; and the vaiious contrivances adapted to fit the animals of the early world to walk or to swim or to fly, show that there were air and water and solid earth. And these facts furnish not merely the only proof that can be given, but a proof which is abundantly satisfactory, that into whatever remote depths of the past we may be enabled to gaze, we shall see there the same orderly working of harmoniously adjusted laws, the same marks of order, regularity, and design. It is not, of course, intended by this assertion of the uniformity of the laws by which natural phenomena are regulated to assert any uniformity in the phenomena themselves. On the contrary, as- suming, as some have assumed, upon grounds which have com- manded the assent of probably a majority of geologists, that the earth was originally a diflfused nebulous mass, and was, when first condensed, fluid with the liberated heat, and that since then it has gradually cooled down until it has reached a point at which the heat received from the sun balances, or nearly balances, that which is lost by radiation — it is obrious that, though the laws according to 14 which the natural forces operate have remaiued identical, yet the amount and direction of the forces themselves must have greatly- changed. Or, to take another hypothesis not so generally prevalent, that all the carbon in the earth originally existed in the air, from which it has been absorbed by vegetation, it is obvious that, although the laws of vegetable and of animal life were the same, the forms in which they would be embodied must have been very different in order that they might be adapted to the different circumstances in which they were placed. In such a case the manifestations of the forces of nature would, under some aspects, be more and in others probably less energetic than they are at present ; but the forces would be iden- tical and the laws which regulated them unchanged. It is often as- sumed that those who assert the same laws have operated through all time, have therefore asserted or implied that their manifestations were uniform. On the contrary, the very identity of the law would necessitate a change in the amount or character of its effects in pro- portion as the circumstances were changed in which it operated. Another, but less certain, inference is that these laws operate likewise in all space. There is undoubtedly proof that two of the forces operate so widely as to make it a matter of safe inference that they operate universally — the forces of gravitation and of light — and this gives scientific grounds for the conclusion that all the other forces which have been shown to be wholly or partially convertible with, or correlated to them, are at least as extensively diffused. At any rate, if upon our earth the force of gravitation, as manifested in a falling body, when arrested is converted into heat ; the same amount of force existing under this new form as has been stopped in the other ; if heat is convertible into light, and if light, electricity, magnetism, chemical attraction, and vital force, under certain aspects, touch and pass into each other, there is a fair ground of inference that when one of these forces is found to exist the others are also present. An able and ingenious attempt to show that the laws which regulate the forces of nature on our globe exist not only in all parts of the solar system, but through- out the whole stellar universe, and that this is true of the particular laws by which intelligence and the capacity of moral and spiritual ideas are, or seem to be, connected with a particular tjrpe of physical organization, which is that of the minority of the human race, is to be found in a work, not bearing the name, but known to be the production of Professor Whewell, "The Plurality of Worlds." And this attempt is the more noticeable considering the general views of the author and the object with which that particular work was composed. The argument of that work consists, so far as relates to this topic, of statements which appear to show- in a very clear and irrefragable manner, that in fact the capacity of intellectual progress and of adequate moral and spiritual ideas, is not merely limited to the human species by virtue of its organization, but even among mankind is limited to particular races and families, as must be assumed in consequence of their organization, since other- wise the argument would lose its point. The author then shows that this organization is essentially related to the constitution of the world, to its amount and proportion of heat and cold, to the pressure exerted by gravitation, to its atmosphere, and to its other conditions. He then proceeds to indicate the essential difference that exists be- tween these conditions upon the earth, and upon the other planets of our system, and in the stars ; and from this he argues that such organi- zation as we find essential to the possession of a power to conceive worthily of God, and to worship him aright; to receive intellectually and to embody in action the revelation which God has given ; could not exist in these planets or in the stars, and that as a consequence the capacities which result from this organization would also be wanting. And from this he deduces, as a conclusion, that the motive which has been so often assigned why these worlds should be in- habited, that their inhabitants might know, and love, and worship God, is devoid of force, because there is every ground in analogy to conclude they would not possess the requisite faculties to enable them to do this. Of course it would be out of my province to enter into any discussion of the validity of this argument as affecting the conclusions which the essayist has deduced from it. But it is relevant to my present subject to remark that he appears to have confounded uniformity of law vrith identity of result. In our world we see that organized beings have existed from times inconceivably remote ; that they have gradually changed from their original type in the direction of a greater specialization of organ and frincticn ; and that as the highest and probably the latest organiza- tion man has appeared: as it would now seem in a low type at the first, but in one which, as it was capable of the improvement it has received, we may also conceive to be capable of yet further elevation; and all this in strict relation to the external influences of every kind to which they have been subject. Now we may have from this a right to argue that the human organiza^ tion, and even the higher types of that organization, are, under the circumstances in which living creatures are placed upon this earth, a necessary condition to the enjoyment of certain capacities and 16 fkculties; but since we have no experience and no analogy which can guide us upon the subject, one of the terms being wanting, we have no right to say that these are necessary in worlds differently con- stituted. The same laws operate there as here, and we may presume that they work towards similar results ; but we know that they work under different conditions and possibly upon differently-arranged or differently-proportioned materials. But are we, therefore, to con- ceive that they cannot result in the gradual perfecting of organiza- tion to as high a degree as has been attained in our earth ; this per- fected organization being as harmom'ously adjusted to the size, gravity, temperature, and composition of each particular world as is man to the world which forms the place of his habitation ? The ultimate difference in the composition of the brain and nerve tissues, and of other bodily tissues, is, as I understand, that in the former there is a certain proportion of phosphorus which is wanting in the latter. And I am not aware of any ground for supposing that element to be absent in Jupiter, or, if it were, for supposing that mind cannot come into relation with the worlds of matter and of spirit, imless phosphorus be present in the animal tissue. But though in this respect I think the essayist has carried his inferences beyond their legitimate scope, I recognize his philosophical Adew of the univer- sality of law ; that it pervades all space as well as all time ; and I have no doubt that when the particular controversy to which this essay gave birth has died away, the beneficial effect of these philosophical conceptions will continue to be felt. I have thus very imperfectly completed the object of this paper. I had hoped, when I first thought of the subject, to have treated of -the idea of law in nature under other aspects, and to elaborate more fully those to which I have referred ; still I trust that I have at least said sufficient to show the general bearings of the subject. The idea of law in nature implies no knowledge of anything but the relations which exists between phenomena ; but it implies that these relations are constant ; that all changes are the results of the forces of nature ; and that these forces act according to invariable laws, which are coextensive with nature in time and in space. If I have leisure I propose, with your permission, to devote one or two other papers to particular manifestations of these laws, under the titles of " Law in Creation" and " Law in History," and then I hope to be able to read one last paper on " The Relation of Science and Theology." LAW IN CREATION. In my former Paper I attempted to show that in nature, so far as our investigations are able to extend, either in time or in space, we find everywhere phenomena manifested according to certain definite laws ; and that this, in fact, is our only conception of nature. In the present Paper I propose to examine what grounds there may be for supposing that the maintenance of organic life upon the earth, and its successive manifestations in the various geological formations in which we are able to trace its appearance, as weR as in the almost infinite variety of living things by which the earth is now peopled, can be brought under the same conception. It is, however, right to state that, though, in the title of this Paper, I have used the word " creation," I have not any intention of suggesting any theory with regard to the origination, of matter or of force. The beginning of things is altogether beyond the domain of science, as I understand it. My enquiries refer only to the law, if any can be shown to exist, of the changes in organized beings, which have occurred since their first appearance on the earth. In entering upon the discussion of this question, however, we are met upon the threshold with objections arising out of the theological views which prevail in reference to the idea of creation, and which, if we may judge from the temper in which every theory upon the subject has been attacked, would seem to render its calm and dispas- sionate investigation almost impossible. It appears to be assumed that there is something peculiarly mysterious and sacred in the origination of species — that it stands apart and isolated from all phenomena — and that, whatever may be the case with other and meaner matters, for which the laws of nature may be allowed to oflfer a sufficient explanation, here at least nature must be considered to stop, and something superior to nature must be invoked. The sun may shine and the winds may blow in obedience to law ; the thunderstorm and the earthquake may be traced to natural pro- 18 cesses ; mountains may rise and valleys be excavated, tides may ebb and flow, the mightiest and the most minute inorganic changes, in- volving as they do the welfare or the destruction of miUions of organized beings, may occur in accordance with and may be the necessary result of the laws to which nature is subservient. This the theologian who knows anything of science wiU admit. But the minutest organism that peoples the water, or as a weU-nigh in- visible speck is seen upon the weathered face of a rock, or hastening the decomposition of what was once a living substance, must, he insists, have required for the origination of the trivial characters by which it is distinguished from allied species, a direct supernatural intervention of the Supreme Being. And he who denies or even doubts this runs no small risk of being denounced as an atheist. Happily, however, in this room we may piirsue our enquiries without any fear of being subject to such imputations. The first notion of creation which certainly most, and probably all, of those who hear me received, was contained in that version of the fourth commandment which ia given in the Book of Exodus — " In six days the Lord made heaven and earth, the sea, and all that in them is." This, taken by itself, was complete and satisfactory. There was no distinction between organized beings and inorganic matter — all ahke owed their being in their present form to the fiat of the Almighty, at a date not quite six thousand years ago. With this view the question of development or of creation by law could have no meaning ; there was, in fact, no place for any such idea. But though this continues to be taught in schools, and, I suppose, also in colleges — ^for error is often thought to be safer than truth — it is a view which no person acquainted in any degree, however slight, with the discoveries of geology during the last half century continues to hold. It is as certain as any conclusion of reason can be that the world has existed as the habitation of organized beings for unknown millions of ages, and that the various species of animals and plants by which it is now peopled are comparatively of very recent introduction, though the existence of some of them must be calculated by probably miUions of years. I cannot better illustrate this part of my subject than by a brief quotation from Professor Owen's recent work on Palaeontology ; and I quote firom him in preference to other authors whose words I might employ because he has been an opponent of every proposed theory of development. " Palaeontology teaches that the globe allotted to man has re- volved in its orbit through a period of time so vast that the mind in its endeavour to realize it is strained by an effort like that by which 19 it strives to conceive of the space dividing the solar system from the most distant nebtdae. " Palaeontology has shown that from the iaconceivably remote period of the depositioa of the Cambrian Eocks the earth has been vivified by the sun's light and heat, has been fertilized by refreshing showers and washed by tidal waves — ^that the ocean not only moved in orderly oscillation, regulated, as now, by sun and moon, but was rippled and agitated by winds and storms — that the atmosphere, besides these movements, was healthily influenced by clouds and vapours rising, condensing, and falling, in ceaseless circulation. With these conditions of life, palaeontology demonstrates that life has been enjoyed during the same countless thousands of years, and that with life, from the beginning, there has been death. The earliest testimony of the living thing, whether coral, crust, or shell, in the oldest fossiliferous rock, is at the same time proof that it died. At no period does it appear that the gift of life has been monopo- lized by contemporary individuals through a stagnant sameness of untold time, but it hasbeen handed down from generation to genera- tion and successively enjoyed by the countless thousands that con- stitate the species. Palaeontology further teaches us that not only the individual but the species perishes^-that, as death is balanced by generation, so extinction has been concomitant with the creative power which has continued to provide a succession of species ; and fia:thermore, that as regards the various forms of life which this planet has supported, there has been an advance and progress in the main. Thus we learn that the creative force has not deserted the earth during any of the epochs of geological time that have suc- ceeded to the first manifestation of such force, and that in respect to no one class of animals has the operation of creative force been limited to one geological epoch ; and perhaps the most important and significant result of palseontological research has been the establishment of the axiom of the continuous operation of the or- dained becoming; of living, things." These being the facts, the view taken of them by those who insist upon the supernatural origin of species — or what I might call the theological view — appears to be that, as soon as, by the slow operation of natural causes, the world had become fitted for the re- ception of organic life, the lowest forms of vegetables and of animals were introduced by a direct supernatural creative act of the Deity. That, being so introduced they increased and multiplied until, by some catastrophe — whether the' result of natm-al law or of miracu- lous interposition is left doubtful, though presumably it must 20 have been the latter — they were all destroyed. That, after this des- truction, when the forces of nature had recovered their equilibrium, another set of animals and plants suited to the new conditions of the elrth was again miracidously created. And that, this process has been repeated from time to time imtil the commencement of the present order of things ; since which period there have been successive miraculous creations of new species of animals arid of plants to take the place of those species which have successively in the slow pro- gress of time become extinct, the creation of man being the last of these. This, so far as I can gather, appears to be the view most in favour, though it is gradually losing its hold of more advanced thinkers, and it may have been superseded by some newer views which have not yet reached me. In any modification which it may receive, however, the essential idea must remain ; and that is, that, whether by a gradual decay of vital force in the individuals of which the species is composed, or by a change of the conditions in which they are placed, either sudden and catastrophic or gradual and regular, all extinct species have perished without leaving any pos- terity; and that, the miraculous intervention of the Creator has been required, by the creation of new species, either to supply the gap thus occasioned, or to prevent its being filled up by other surviving species. This view, in its general results, suggests order and regu- larity as the rule, both in the inorganic and organic world; all things going on in accordance with natural laws for thousands or for millions of years ; then, suddenly, a breaking up of the whole system, for some unexplained and inexplicable reason, and in some incomprehensible mode ; then a period, longer or shorter as the fancy of the individual speculator may determine, of lawlessness and confusion ; and then, the beginning of a new era of order and regularity in a world of changed conditions and peopled by new inhabitants organically adapted to the change. I must say it appears to me that to make this conception complete it requires the old Persian view of two opposite powers — Ormuzd ruling during the periods of repose and order, and Ahriman obtaining the mastery in those of confusion and destruction. To suggest that the Supreme Being becomes dissatisfied with the result of his labours and so breaks up the system he has established -^ or to suppose that the machinery he has set in motion gets out of gear and knocks itself to pieces, or becomes worn out with age — and one of these conceptions appears necessarily involved in the hy- pothesis I have described — does seem to me to introduce low and unworthy views of his character and works. Thewhole view, how- ever, is thoroughly anthropomorphic. It is the conception of an 21 artificer, hampered by his materials, who has to make essay after essay until the elements with which he has to deal grow plastic under his hands, and he can at length mould them into a form which adequately embodies his conception. This is not the view of God which either reason or revelation suggests or sanctions ; and that such a view should ever have been adopted, and especially that it should have been supposed to save the credit of revelation and to satisfy the requirements of reason, is a marvel to me ; and none the less so that I once myself held very similar views. The history of this theory is, in fact, something like that of the Ptolemaic theory, which, starting from the assumption of the im- mobility of the earth in the centre of the system, and accounting for the movements of the sun and the planets by " cycle on epicycle, orb on orb," grew more and more compKcated with every improve- ment in the means of observation, until Alphonso of Portugal could say, with the avowed or silent assent of all astronomers, that if God had consulted him in arranging the motions of the heavenly bodies he could have shown him a much better way. So here, starting from the assumption that the origin of species is necessarily a phenomenon altogether beyond any force or law of nature, either known or un- known, and therefore one that could only have been produced by a miracle, the result has been that, to explain the succession of species from the first manifestation of life upon the earth up to the present moment, theories more and more complex have required to be in- vented ; until every idea of order and regularity is lost in the profu- sion of perpetually recurring miracles, and the conception presented of the Creator is a good deal more like that of a workman putting his hand to his work, than that of such a Being as revelation discloses and reason recognizes. It must, however, at the same time be admitted that most of the theories which have been put forth on the other side have been, to use the mildest term, of a highly speculative and fanciful character. The theories of LaMarck and DeMaillet were as little accordant with observed phenomena, and as little capable of proof, as that theory of immediate creation which they were invented to supersede ; and they were easily capable of being presented in a ludicrous point of view. The description of them in the lines of Mr. Hosea Biglow when he says — "That the fears of some monkey whose holt chanced to fail Drawed his vertebrae out to a prehensile tail," is scarcely an exaggeration of some of the processes which were supposed to have been opei'ative in order to bring about the observed 22 modification of organs and habits in allied classes of animals. And in the recent work in which the theory of development has been temperately and ably supported, with many modL6.cations drawn from more extensive observations of facts, "The Vestiges of Creation," there appears to me still to be the same weakness. All of these various theories, although they shadow forth with more or less com- pleteness what we may conceive might have been, are deficient under two aspects — they do not rest upon causes which we can ac- tuaUy see in operation, or can infer certainly fi-om the analogies of na- ture ; and theyleave unexplained certain classes of facts which any complete theory is bound to accoimt for. With, regard to the former objection, it is not the rule that a change of circumstances or habits involves a change of organization ; and with regard to the latter, sudi phenomena as those of the colour of some insects being ad^ted to the colour of the leaves or branches where they are usuallyfoimd — the colour of the eggs of some birds being similar to that of the places where they are deposited — the peculiar organization and habits of neuter insects, and other analogous facts — are left unac- counted for. But it should in fairness be remembered that these defects are no more than we must expect to find in the first attempts to explain phenomena so complicated and so far beyond the limits of our ordinary experience as those with which this theory professes to deal ; and that it is the necessary, or at any rate the invariable course of the human intellect, to attain to a complete and satisfactory theory upon any subject, only after framing and abandoning many imperfect and erroneous theories. It might almost be said that we can only reach truth -through the gate of error. And these theories have answered some important purposes. They have brought under one general view all the phenomena which they profess to explain — they have shown to a certain extent the relation and interdependence of these phenomena ; and by their very failures they have pointed to the path in which a true explanation of the facts is most probably to be found. In attempting to form any theory upon the subject the first ques- tion to be determined is, whether in reality there has been any real development or progress — whether the plants and animals of the' present time are of higher classes and more perfectly organized than those of the earliest times ; and if so, whether that elevation of type and improvement in organization is such as to point to a gradual progress from the simplest forms, or merely to an improvement by the simplifying or specialization of more complex organizations. These are questions which are far from being settled ; but upon the 23 whole it appears to me that the evidence, both negative and posi- tive, establishes the conclusion that there has been a progress from lower to higher classes of beings, and from the more simple to the more highly organized forms ; and that although a part of that progress has consisted in a specializationof organs, yet that this has on the whole been accompanied by a gradual elevation of the type, the lowest organisms standing at one end of the scale and man at the other. This conclusion is asserted or admitted by almost every geologist, and by none more decidedly than by those who are opposed to the doctrine of transmutation of species. That, in the order of creation, the invertebrate preceded the vertebrate type, and that, among vertebrates, fishes preceded reptiles, and reptiles mammals, and that, last of all, man appeared,- are conclusions to which all the evidence points, and in which all, or almost all, enquirers agree. When, however, the question is raised whether the same evidence of progress exists among the various species of which these families are composed, and still more, whether there is any indication of a passage from one class to another, there is no longer the same unanimity. And it is undoubtedly the case that the earliest fishes, reptiles, and birds, of which we have any remains, are not either of small dimensions or of the lowest organization. With regard to fishes. Professor Owen, from whom I again quote, says, "A retrospect of the genetic history of fishes imparts an idea rather of mutation than of development to which the class has been subject in the course of geological time." And again, " It (the present period) repre- sents rather a period of mutation of the piscine character depending upon the progressive assumption of a more special piscine tj^e, and progressive departure from a more general vertebrate type." " The comparative anatomist dissecting a shark, a polypterus, or a lepi- dosteus, would point to the structures of the brain, heart, generative organs, and, in the last two genera, to the air-bladder, as being of a higher or more reptilian character than the corresponding parts would present in most other fishes. But the palaeontologist would point to the persistent notochord and to the heterocercal tail in palaeozoic and many mesozoic fishes as evidence of an ' arrest of development' or of a retention of embryonic characters in these primeval fishes." Again, with regard to reptiles, he says, " A retrospect of the foregoing outline of the palaeontology of the class of reptiles shows that, unlike that of fishes, it is now on the wane, and that the period when reptiles flourished under the greatest di- versity of forms with the highest grade of structure and of the most colossal size is the mesozoic. The progress of air-breathing verte- 24 brates, graduating Ijy close transitional steps from the water- breathing class, has been checked, as if it had been unequal to the exigencies and life capacities of the present state of the planet. Eeptiles have been superseded by air-breathers of a higher type which cannot be directly derived from the class of fishes. A more generalized vertebrate structure is illustrated in the extinct reptiles by the affinities to ganoid fishes shown by the ganocephala, laby- rinthodontia, and icthyopterygia, by the affinities of pterosauria to birds, and by the approximation of dinosauria to mammals." With regard to birds the evidence is so imperfect that scarcely any general conclusion can be drawn ; but the earliest indication of the existence of this class of vertebrates, the fossil footmarks found in the sand- stones of Connecticut, show birds of a size apparently surpassing any at present known to exist. With regard, consequently, to these three classes of vertebrate animals, there appears to be no evidence of any links connecting the earlier forms with any lower organiza- tion, and these earlier forms are themselves highly organized and many of great size. From their first appearance there are indica- tions of change of specific character, which in the fishes has resulted in the general establishment of true fish-like forms without any of the reptilian characters found in the palaeozoic fishes, and in the loss of the embryonic characters by which those paleozoic fishes also appear to have been distinguished. In the reptiles there has also been a similar specialization, the existing reptiles having for the most part lost the fish, bird, and mammal affinities which the earliest forms displayed. The evidence, then, which we possess, con- fining ourselves to these two latter classes for the moment, shows a change in each in a certain direction, which so far would seem to be favourable to the idea of transmutation of species — at any rate within these classes themselves, and possibly also of a transmutation from the class of fishes to that of reptiles ; but it does not aiford any support to the idea of the derivation of the class of fishes fi-om a lower class. It does not, however, contradict such an idea, unless upon the supposition that the evidence is complete, and that the fishes whose remains we have discovered were the earliest fishes that existed. With regard to mammals the evidence appears to be, that the earliest known fossils of this class are found in very early deposits, and are, so far as they can be identified, of the lowest type ; then that there are enormous periods ol time, and deposits rich in fossils of various classes, but with no mammalian remains, until we arrive at the tertiary deposits, where fossils of this order abound, gradually becoming more and more similar to the existing order of 25 animals. Taken generally, then, it may perhaps be stated that the result of the palaeoutological evidence shows there is in a certain sense a progress from the earliest times to the present — ^that in some cases, more especially in the invertebrate class, and most noticeably as we approach the existing order of things, where the evidence is more continuous and perfect, species appear to pass into each other by almost insensible gradations, but that this seeming continuity is frequently interrupted, and that there are intervals between the various classes which contradict the theory of transmutation, if we can assume that there are no missing Units which might, if pre- served, have filled up the gap. It is, of course, essential to any theory which can be received as sufficient that it shall not be contradicted by the evidence. The evidence may not in the first instance completely establish the theory — it may not in some cases ever prove sufficient to do so, be- cause the evidence itself may be hopelessly defective. And there may even be facts which the theory is inadequate to explain, without destroying its claim to be received, conditionally, or even absolutely. As, for instance, the theory of gravitation was insufficient to explain the perturbations of the planet Uranus until the discovery of the planetNeptune ; and Kepler's laws to explain the observed difierences in the period of the occultation of Jupiter's satellites, according as they wera nearer or more distant from the earth, until the velocity of light was admitted and determined. Nevertheless, these theories were accepted, and astronomers addressed themselves to the work of discovering the cause of the seeming exceptions. And so, in any theory that may be framed in order to account for the origin of species, it is no vahd objection to its soundness that there are ap- parent exceptions and anomalies which it fails to explain, though it would be a conclusive objection if there were any facts by which it was directly contradicted. If, for instance, to refer to a work which is probably well known to all of you, there was proof that the gi- gantic asterolepis, discovered by the late Hugh Miller in the Caith- ness Sandstones, and so graphically described by him in his " Foot- prints of the Creator," was the earliest fish that ever existed, as it is one of the oldest fishes of which any trace has been found ; and if there were no invertebrate animals which approached nearer to it than those whose remains have been discovered ; such a fact woidd, as it seems to me, directly contradict and be fatal to any theory of development or transmutation. But the fact that this organism is the oldest fossil vertebrate discovered, in our profound ignorance of the innumerable organisms which peopled the palaeozoic seas prior 26 to and contemporaneous with the deposit of the old red sandstone, almost the only trace of which is foxmd in those Caithness Sand- stones, of itself proves nothing against any theory. It only leayes the application of the theory imperfect so far as these animals are concerned, inasmuch as it is impossible to show whether or in what manner their origiaation conformed to the theory. Assuming, then, what no one will now deny, that the materials of evidence are incomplete; that, whatever theory we may adopt, its appUcatian must inevitably be ia a great measure conjectural ; the questions for our decision are, first, what is the apparent bearing of the evidence so far as we can trace it — and second, is there anything, in the nature of the case or in the seeming exceptions, which should prevent us from adopting this apparent conclusion as true ? Before attempting an answer to these questions there are, however, certain general considerations which it is necessary to bear in mind. In the first place, then, birth and death, extinction and repro- duction, are correlative, and in the order of nature supplement- and indeed almost imply each other. The causes which produce one set of phenomena are therefore presumably sufficient to account for the other. If the death of individuals results from the laws of nature, so also w^e may presume will their birth ; if the extinction of species is due to natural causes, so we may presume is their origination. Throughout the past the two processes have gone on together,"both with regard to individuals and to species ; and they appear at all times to have balanced each other, so that on the whole there has been neither excess nor deficiency. Their conjoint operation has been, moreover, a necessary condition of the progressive elevation of the type of organized beings. As, therefore, we know from our own recent experience that natural causes will produce the ex- tinction of species, there is a strong aniecedent presumption that natural causes may also produce their origination. In fact, to deny this is, by an almost necessary implication, to assert that the world is so arranged as that natural causes produce supernatural conse- quences. The occasion in nature for the origination of a new species is that there is a place for it, either by reason of its greater fitness for its new position, or by reason of the diminution or ex- tinction of some other species, and this is unquestionably a natural cause. To assert, then, that the production of a new species, which is produced because there is this place for it, and would not be pro- duced, for it could not exist, otherwise, is in effect to attriUute supernatural effects to natural causes. And, in the second place, the general, if not the universal, rule is 27 that there is now no origination of the vital force. Excepting with ihe BJiost elemental^ forms, if even they are to be excepted, it ap- pears now to be established, or at any rate it is the almost universal opinion of naturalists, that there is no such thing as spontaneous generation — ^that the whole organic life of the globe, in all its com- plexity and profiision, is a continuation of former life without any interruption or break. Myriads of germs possessing vital force are never developed — myriads of living beings in every generation die without reproducing their species ; but organic life is always the con- tinuation of previously-existing life. The life of the offspring is a prolongation of the life of the parents — the germ developing itself according to definite laws, so as in its full growth to be specifically identical with the parent, though individually distinct, and within certain limits different. "Whatever doubts may rest upon other questions connected with this subject, upon this there is none — that organic life, in all but th% most elementary forms, is but the mani- festation in new elements of the same life which before existed. There can be no break in this chain. If a seed die, it rots and nothing springs from it. In order to the growth of the plant it is essential that the vitality of the germ remain unimpaired; and then, by some power, which in our ignorance of its nature we call the vital force, and by some process, which as yet we are unable to ex- plain, it attracts from the surrounding inorganic elements the mate- rials for building up a perfect plant. Now this fact, which is most strongly insisted upon by the opponents of all theories of develop- ment or transmutation, appears to me at any rate to involve a very strong argument against their theory of the origination of species in some unexplained manner, but not in the course of ordinary generation. For, assuming, as they assert, that all new species are formed independently ; either by infusing life into some newly-formed germ which shall develop itself into mature and complete being by assimilating from the surrounding elements the necessary materials ; or else by shaping those elements at once into the perfect form of the new animal or plant — and it must be presumed that one or the other of these metiiods is intended — then spontaneous genera- tion is just what we should have a right to expect ; and in the con- ditions of the globe, changing as they are in every locality from year to year, we should always be on the watch to detect these new manifestations of creative power. From the earliest ages of which the crust of the earth presents a record, down to the present time, there has been a change in the two directions of extinction and renovation — species dying out, and their places being supplied by 28 new species ; and as at tte present moment the process of extinction of species is going on, we have a right to presume that the cor- responding process of the origination of new species is going on too. If, therefore, this origination is not in the way of ordinary genera- tion, to ns it must necessarily appear as spontaneous generation. It would consequently be wise in the opponents of the idea that species can be originated as a result of the ordinary laws which regulate the succession of organized beings, to re-examine their ob- jections to the theory of spontaneous generation, and to consider whether, by their opposition to that theory, they may not have de- prived themselves of opportunities of seeing the actual manifestation of that miraculous creative energy in which they believe. It may, no doubt, be said that there is yet a third method. The animal or plant might be created in the theological sense — that is, formed out of nothing ; the very elements of which it is composed might be called into existence ; and the being thus miraculously origi- nated might be placed upon the earth, perfect in organization, with matured instincts and powers, supematurally implanted and directed. And this appears to be the view of the learned author of the Eclipse of Faith, at least with regard to man. But even in this case, since it would be necessary, in order that the being thus created should be nurtured, and Uve, and propagate its species, that the elements of which it is composed — ^the carbon, oxygen, hydrogen, nitrogen, phosphorus, iron, sulphur, and the rest — should be absolutely the same in their nature and properties with those which already ex- isted, so that the most minute chemical analysis should fail to detect the slightest difference, there would be no possibility of verifying this supposed method of origination, and, to the spectator who wit- nessed the phenomenon, it would stiU, if he could believe his eyes, be no more than an apparent case of spontaneous generation. Whether it be a germ into which a new principle of vitality is infused, and to which a new form of development is given ; or whether the inorganic elements suddenly flash into the organized tissues which constitute the perfect form ; or whether the very substances of which these organized tissues are foi-med are contemporaneously called into existence, to our observation and to our understanding there is and can be nothing but the appearance of spontaneous generation. Undoubtedly, however, there are considerations connected with the idea of spontaneous generation which account for the disfavour in which it is held by the opponents of the idea of the transmuta- tion of species. For, inasmuch as this spontaneous generation would be nothing more than the apparent evolution of the vital force by 29 the union or combination of certain elementary substances, in no way to be distinguished from the evolution of the electrical force, or of chemical forces, from similar imions and combinations ; nothing to the common apprehension would more tend to connect the idea of life with the idea of law than such an occurrence. And however miraculous the occurrence in fact might be, there would be no pos- sibility of the most eloquent theologian, or the most acute controver- sialist, proving upon scientific grounds its supernatural character. We may, however, for the purposes of the present discussion, assume, as a fact resting upon all the evidence which in the nature of the case it is possible to bring to bear upon the subject, that at any rate, excepting in the case of the most simple and elementary organism, spontaneous generation does not exist. Every living thing has sprung from a parent by the process of ordinary generation. And, upon the other hand, it is an admitted fact that generally, if not imiversally, species remain constant for many thousands of years ; that no case of the passage of one species into another has ever been verified ; and that the divergencies between known species are in very many instances so great as to negative the idea that they can have passed one into the other without having also passed through transitional stages of which no traces can be found. On each side there are unquestionable and admitted difficulties. The question, then, is whether it is more probable that, we will say, the first pair of elephants was produced by ordinary generation from parents dif- fering slightly from themselves, who had themselves been similarly produced; or whether they were the outgrowth of germs inde- pendently originated, and miraculously developed into the form of an elephant, by a process of assimilation which we not only do not know but cannot even by any process of imagination represent to ourselves ; or whether the various elements of which their bodies ^ere composed were suddenly brought together from the surrounding earth and air and plants and water, and formed into the complete forms of a male and female elephant, into which forms life was mi- raculously infused, and which were also at the same time and by the same miracle endowed with all the instincts necessary for their own preservation and the propagation of the species. Tried by the test of reason, and by their conformity to the laws of nature, which are to us the expression of the Divine plan, there can be no doubt that the first of these suppositions is the most probable — nay, is the only one conceivable. There may be difficulties in the way of any theory that may be framed to accoimt for the precise mode in which the species of elephants has originated — ^how the specific differences by 30 wliich that species is characterized and defined could have been produced, and how, being produced, they could have remained so permanent ; but these difficulties, great as they nndoubte?ily are, almost disappear by the side of those by which either of the other theories or any that can be substituted in their place is surrounded. It may, no doubt, be said that the cases are different — that ia the one case, when we undertake to explain, and account for the pheno- mena, the theories which we frame for this purpose are properly amenable to reason and must satisfy the conditions of science ; but that when reason is con&ssedly abandoned, and science pronounced incompetent either as a clue or as a test, and when it thus becomes necessary to invoke the direct supernatural iuterposition of the Deity, we have no right to subject the mode of his operation to criticism upon rational or scientific grounds. I do not enquire how far this objection may be well founded in principle, but it is obvious that it proceeds upon the assumption that the supernatural character of the phenomenon is demonstrated, at least negatively by the ex- clusion of every other hypothesis ; while, in feet,, that is the very question at issue. And, until this demonstration is furnished, we of course are entitled to examine the apparent appropriateness and adequacy of the processes which it is proposed, or which it is pos- sible, to substitute for those which we have suggested. But, to revert for a moment to the case of the elephant, there is a further diffilcully suggested by his peculiar organization. In his massive foot, enclosed, in one continuous integument, and combined together into a solid mass, there is- tiie same number of separate bones, occupying the same relative positions, as in the human hand. How or why this should have occurred on the theory of supernatural creation, no one has ever suggested, excepting upon the anthropo- morphic idea that the Creator has, throughout the whole animal kingdom, designedly limited himself to a certain type, and has, if I may venture to employ the phrase, shown his skill and ingenuity by the innumerable modifications of that type whieh adapt it more or less; perfectly to the circumstances of the particular animal : thus accomplishing indirectiy what might otherwise have been accom- plished directly — ^imperfectiy what might have been accomplished completely, and even creating, useless appendages and rudimentary structures, such as, for instance, the abortive teeth in the young whale, for no other purpose than to preserve this unity of type. That this unity of type does exist is no doubt incontestable, as well as that it has existed from all time. In tiie past, as well as in the present, there is nothing at variance with this plan. Whatever 31 discoveries may have been made, and however widely the forms dis- covered may depart from those with which we are familiar, they are all part of the same system, and take their place in the series — generally tending to bridge over the intervals which were previously supposed to exist between known forms. As it has been said, we never come upon a fossil centaur or a palaeozoic mermaid. Every new discovery in fact only tends to bring into greater union and harmony the existing forms, and to demonstrate yet more com- pletely the unity of plan which pervades all nature. The only question here is, what inference are we entitled to draw from its universality and permanence ? It is scarcely necessary to say that this unity of plan, at any rate, becomes intelligible on the supposition that aU species are connected through the medium qf a common an- cestry, if it does not even furnish a presumption in favour of that conclusion. It is a fact eminently consistent with such an idea, as- taken by itself it may be supposed to be also consistent with the opposite idea of direct creation, all forms having their origin in the same creative mind. But while on a general view this observed unity is consistent with the latter conception, the manner in which it is carried out is full of difficulties. When, for instance, the same bones in the same relative positions are found in the hand of man, the " trowel" of a mole, the paddle of a whale, and the hoof of sta. elephant — when the same multiplied points of ossification in the skuU of the human foetus which are so usefid in parturition are also found in similar order " in the skull of the embryo kangaroo which is born when an inch in length, and in that of the callow bird which breaks the brittle egg," these facts, which are significant on the Mie supposition are meaningless and unintelligible on the other ; and these, though among the most striking, are only an insignificant fraction of the vast number of similar instances. Another fact which points in the same direction is the existence of what have been termed specific centres of creation. It is well known that whenever any two tracts of land, whether large or small, are entirely separated from each other, then whatever may be the analogy of soil, climate, and natural conditions, there is almost always an absence of specific identity between the animal and vegetable forms found in the one and in the other, while at the same time there is a strong general resemblance between them. Thus, in tiie temperate regions of Europe, of Asia,, aai of North America there is a striking resemblance in the general aspect of the flora and faima, while there are comparatively very few plants or animals specifically the same. And, in connection with this, there is the additional 32 circumstance that, in small islands, the plants and animals found there generally resemble those 'which are found in the nearest con- tinent, though they diiFer specifically. Nor can it now be said, as once used to be said, that there is such a relation between the or- ganisms found in any country, and its conditions of soil, climate, and temperature, as that they are better adapted the one to the other, than without these specific differences could have been the ease. For it has been foimd that both plants and animals, when introduced by the agency of man into a new country, and there left to themselves, have spread themselves over the face of the land to the exclusion and consequent destruction of the native races ; thus proving themselves better adapted to their new home than species which upon this theory were created specially for it ; and even some- times showing that their new home was better adapted to themselves than that from which they- had been transplanted, and where they were first found. There are two other general facts pointing to the same general conclusion to which I may advert, merely mentioning them. The one is the existence of apparent imperfections in organizations, which may be illustrated, to select one instance only, by the circum- stance that the bee loses its sting and so its life when it uses it ; and the other is the manner in which animals are adapted to habits of life apparently at variance with their organization, as in the case of the water ouzel ; or in which the purposes of the organization appear to be missed, as in the case of the musk duck of the Murray, which, though having wings, is unable to fly, and only uses them to paddle itself along more quickly. All of these are inexplicable on the theory of specific acts of creation, but they are capable of explanation on the hjrpothesis, which they aU in their turn tend to support, of the transmutation of species. It may be said in answer to these last suggestions that it is nothing uncommon in nature to find phenomena for which we are unable to account, and that imperfection is the universal attribute of finite beings. I admit this, and I admit also that it would be an Unusual and, so to speak, a suspicious circumstance if anything were found not having these marks of obscurity and incomplete- ness. The analogy of nature leads us necessarily to anticipate their existence ; but, if any opponent of the theory of creation according to law refers to the analogy of nature and relies upon it, he must be content to be bound by the witness to which he has appealed. And that gives no support to his view. On the contrary, we see every- where in nature general laws operating; working, as we believe, on the whole, for the general good, but causing in their influence much individual suffering — everywhere we see evidences of the highest wisdom as shown in the establishment and maintenance of perma- nent order and regularity ; but we look in vain for any marks of in- terruption or violation of those laws or of that order. Everywhere we see natural causes working to the accomplishment of the Divine purposes ; nowhere do we find anything to show us that those ordained causes are inadequate, or that they require special inter- positions to prevent their failure. The analogy of nature leads us, therefore, irresistibly to the conclusion that whatever we see around us owes its origin to the same laws to which obviously it owes its preservation ; and there is nothing in nature, whatever there may be in the regions of speculation or of sentiment, to lead to any other conclusion. I had intended to have said something in detail of the theory of Mr. Darwin, which, though confessedly incomplete, at any rate offers a solution of the problem of the origin of species strictly in accordance with what we know from experience, and can infer from analogy, of the operations of nature : but I find that I have not left myself space for the purpose. His theory is based upon the ob- served fact that in all, or almost all, organizations there is a tendency to slight variation, and that, by taking advantage of this tendency and selecting for breeding those animals which vary in any par- ticular direction, we are able to accumulate these variations and to cause in the course of a comparatively few generations very percep- tible differences of structure and habit. And from this, taken in connection with the constant struggle for existence among indi- viduals of the same and of different species, arising from the cir- cumstance that in general only a fraction of those who are born can live and propagate their kind, he argues that in the battle of life any variation, however slight, which gives any Individual an ad- vantage, will tend to the preservation of that individual, and to his having offspring, some of whom at least, on the principle of the hereditary transmission of Individual peculiarities, would partake of the peculiarity of their progenitor, possibly in a greater degree, and would thus be more likely to survive and to bear offspring re- sembling themselves in the characters to which their own preser- vation was owing. And in this manner, time being allowed, he assumes that any amount of deviation from the original species is capable of explanation. Stated In this general manner, there is nothing in the theory which is not within the limits of a sound analogy ; but whether, when applied to the facts, it wUI suffice for 34 their explanation, is an altogether different question, and one upon which it would be premature to pronounce confidently. But at any rate it has the merit of proposing a vera causa, something that we know to exist, and whose operations we are, within certain limits, able to trace ; and in the sketch of his theory which Mr. Darwin has published, he has accumulated an immense amount of facts, of many of which I have already availed myself, which tend to show that at any rate this principle has the merit of offering a probable so- lution of the question. And although his theory, from the extent to which it rtms counter to cherished prepossessions, is certain to excite strenuous opposition, I have no doubt that it will be ultimately recognized as having commenced a new era ; and that it will be conceded to Mr. Darwin that if he has not himself effectually solved the problem, yet that he has opened up the true way to its ultimate solution. There is one objection to this theory as developed by Mr. Darwin proceeding from the pen of Sir Jphn Herschel, to which, however, I may before concluding briefly advert, because it is a type of much that has been vrritten against the theory, and of more that has silently operated to prevent its reception. Sir John says, " we can no more accept the principle of arbitrary and casual variation and natural selection as a sufficient account per se of the past and present organic world, than we can receive the Laputan method of composing books (pushed a Voutrance) as a sufficient one of Shakspeare and the Principia. Equally in either case an intel- ligence guided by a purpose must be continually in action to bias the direction of the steps of change — to regulate their amount— to limit their divergence— and to continue them in a definite course. We do not believe that Mr. Darwin means to deny the necessity of such intelligent direction. But it does not, so far . as we can see, enter into the formula of his law, and without it we are unable to conceive how the law can have led to the results." So far Sir John, and there is no doubt that he expresses the senti- ments of very many persons, though I confess there is scarcely any person from whom I should not have been less surprised to hear such sentiments than from him. This objection seems to me to ignore all that has been accomplished, in no small degree by his own labours, to show how the laws which the Creator has impressed upon matter are sufficient of themselves, and enable us to dispense with the imaginary vortices of Descartes, or the angelic intelligences of Kepler, that kept the planets spinning on their axis. It leaves out of consideration what Bishop Butler had said of the superior 35 evidences of wisdom and power furnialied by a law which executes itself, as contrasted with one which requires the perpetual inter- vention of the Lawgiver in order that it may be executed. And, in reference to the special subject, it forgets that, inasmuch as this law of variation can only work in so far as it tends to give to the indi- vidual some advantage which otherwise he would not have pos- sessed, it has within itself the necessary guide and check. The theory assumes that variations, hurtful as well as beneficial, may occur, and perhaps with equal frequency ; but that only those which are advantageous to their possessors have any tendency to per- petuate themselves ; while those which are injurious have a direct tendency to prevent their own perpetuation; inasmuch as they place the individuals in whom they occur at a disadvantage in the struggle for life, and so on the whole ensure that they shall not survive or propagate their species. This law, then, if established, does not require that an intelligence guided by a purpose should be con- tinually in action to bias the directions of the steps of change, for the intelligence which has established the law has rendered it self- executing and self-regulating. And this surely gives us a higher conception of the Divine wisdom and power than a system which was so imperfect as to need perpetual interference and adjustment. Once it was thought that the planetary perturbations were such as to threaten the system with ruin, unless the Creator should interfere to restore order ; and there were not a few who looked upon this as one of the proofs of the existence of a Deity. But now that we know that God has made these worlds fast for ever and ever — that he has given them a law which cannot be broken — ^that by this law they win, so. far as our foresight extends, continue harmoniously in their courses for all time — have we not a higher and a worthier concep- tion of his wisdom, and even a more convincing proof of his ex- istence, than could be derived from any fancied imperfection in his plans, because that imperfection might, to our limited view, appear to require his personal interposition ? The highest evidence of the wisdom, and the most adequate, or I would rather say the least in- adequate, idea of the character of God, appear to me to be derived from the eontemplation of all things, whether inorganic, vital, mental, or spiritual, working together, obscurely perhaps but unerringly, towards the accomplishment of results which he has preordained, in obedience to laws which he has established. LAW IN HISTOEY. The idea of Law in History implies little more tlian the application to communities of the conception involved in the familiar phrases which we so frequently employ in speaking of individuals — " one would not have expected it of hini," and, " what else could he expect?" It implies that the conduct of nations, no less than that of individuals, and just because nations are made up of individuals, is the result of the character and circumstances of the nation ; and that its destiny is, to a certain noticeable extent, the result of its conduct. It however implies, further, that the character and circiun- stances of the nation are themselves the orderly result of something that has gone ])efore, which has made them what they are ; and that, whatever may affect its destiny, not as the direct result of its own character and conduct, must either result from physical causes, which again result from the operation of physical laws, or from the contact of other nations, whose conduct towards it is in the same manner determined by their own circumstances and character. But in all these respects the idea of natural laws as applied to nations resembles, in its essential particulars, the conception which we form .with regard to individuals. And it is so much a matter of common experience that the conduct of any individual is determined, first, by what he is in himself, and secondly, by the circumstances in which he is placed and the motives which arise out of those circumstances ; and that, just in proportion as we are acquainted with these, we should be able to anticipate what he will feel and do in any par- ticular conjuncture ; that few would experience any difficulty in extending the conclusion which is thus found applicable to indi- viduals to the case of nations. The object, then, of the present Paper will be, first, to enquire whether a general survey of the observed facts of history supports this first impression, and what are the elements of the law thus deduced. The first general conclusion, which springs from the most ele- 37 mentary acquaintance with history, is that, among what we call civilized nations, there has been, on the whole, a progress in all subjects — ^material, mental, and moral ; and that this progress has resulted from the circumstance that, as a rule, each generation has been enabled to avail itself of the experience of those which have gone before ; and to make the acquisitions and discoveries of its pre- decessors the starting point for new discoveries and gains. No doubt there have been numerous and signal exceptions to this. Wars and despotisms have not only at aU times checked progress, but they tave sometimes even thrown nations back to a condition of barbarism in which they have lost the knowledge which their ancestors possessed, and have almost forgotten its existence. But these are the exceptions ; and in spite of these the human race has continued to advance. This is so obvious that it is unnecessary to attempt to prove it, and scarcely necessary to give any instance by way of illustration. A railway train with its engine anH carriages, as compared with the carriages, or rather cars, which are figured on the monuments of Thebes or Nineveh ; and these latter as con- trasted -with the entirely primitive and, I presume, patriarchal methods of locomotion employed by the natives of this land ; or the gas lights which in almost all the large towns of the civUized world render the streets as passable by night as by day, and the moderator, argand, paraffin, kerosine, and other lamps for domestic use, as com- pared with the torches and lamps of Egypt and Assyria, or of Greece or Rome ; as these latter, with the absence of aU means of artificial illumination among our natives, whom we may perhaps take as types of the primitive man — not indeed in colour or in organization, but in knowledge— may be referred to for the purpose of illustrating the reality and the extent of this progress in the material elements of civilization. And it is also obvious that, in the very nature of things, this progress implies that every successive step is contingent upon those which have preceded it. The knowledge of auy given fact is the necessaiy condition for the acquisition of the knowledge of all other facts dependent upon it — the possession of an instrument is the necessary condition for the execution of aU the works which, without that instrument, could not have been accomplished. Thus, the knowledge of the properties of fire in smelting metals, and in reducing them into such a form as that tools could be manufactm-ed from them, necessarily preceded the formation of those tools ; and the possession of those metal tools was a pre-requisite to the erection of temples and palaces, the construction of ships, the making of armour and weapons, and, in fact, for the accomplishment of all the 38 •various purposes to whicli these tools were devoted. Under this aspect, therefore, the development of humanity must have been, as it must continue to be, progressive. And it may be added, that the first steps of that progress must have been almost inconceivably slow. Let any one compare, for instance, the mode of melting and forging iron at the present moment in use among the natives of India, with that which is shown to have been in use in Egypt, certainly some three thousand years ago, and observe the little improvement which has been made 'in that long interval, and he will then be able to form some estimate of the smallest period necessary in order that the art of metallurgy should have been raised to that rude stage, even after the possibility of fusing and employing metals had been discovered. And, if we may judge by analogy, the period which must have elapsed before that discovery must have been even yet more extended ; since it would seem inevitable that the first stages of invention, unguided by theory, and unaided by the imple- ments which invention itself creates, must have been the slowest and longest. With regard to the mental progress of manMnd it may be sufficient to adduce by way of illustration the differential calculus as compared with the arithmetical methods known even to the most advanced of the Greek mathematicians, and this with the primitive method of counting by the fingers and toes ; or, better stiU, we may refer to the general amount of knowledge, difiused through the majority of the inhabitants of every civilized country, as contrasted with the inevitable ignorance of the peoples of an- tiquity, upon all subjects excepting those of a directly practical character, and, even upon these, outside of the class which needed to employ the knowledge in practice. And, with regard to the moral progress, it is sufficient to refer to the wide difference between such conceptions of the character of the Supreme Being as are involved in the phrases " Jehovah smelled a sweet savour," " Jehovah rested and was refreshed," " It repented Jehovah that he had made man," and those which are conveyed by the words " God is a spirit," " In him there is no variableness nor the shadow of turning,'' " Jehovah, the maker of the ends of the earth, fainteth not, neither is weary ;" or, under another aspect, to contrast the idea of the Divine government involved in the accormt of the slaughter of all the first-bom of Egjrpt to punish the obstinacy of their king, the command to exterminate the people of Canaan, and the sacrifice of the grand-children of Saul to stay a famine, with those implied in ' the phrase " God willeth not the death of the sinner, but rather 39 ' tltat he should turn from his wickedness and live," or this, " He bath showed thee, oh man, what is good, and what doth the Lord require of thee but to do justice and to love mercy, and to walk humbly with thy God ?" or this, " Suppose ye that those upon whom the tower of Siloam fell were guilty above all who dwelt in Jerusalem" — ^in order to see how great is the progress under this aspect. And, as the conceptions which men actually form of the Being whom they worship, however those conceptions may have originated, or from whatever source they may have been derived, constitute the ideal to which they, for the most part, seek, consciously or unconsciously, to conform their own life, and the test by which character and con- duct are tiied ; this progress in the ideas formed of the Divine character forms a standard by which we may approximately estimate the moral progress of man. And this is the more noticeable when we remember by how wide an interval even the earliest of these conceptions, involving, as they did, the idea of the Unity of God, and that he is the moral Governor of the world, were separated from the fetichism and polytheism of the surrounding nations, and from the degrading idolatry and shameless practices with which this fetichism and polytheism were associated. And not merely do we thus find proofs of a progress of our race under these aspects ; and all progress implies causes, and suggests laws, according to which those causes operate ; but we are also able to trace, to a certain extent, the causes of the growth and decay of empires and of states, and to see in what manner and by what in- fluences this general progress has been interrupted, and sometimes apparently changed into a retrograde movement ; often by the very means employed for the purpose of accelerating or securing its advance. It is not necessary for the purposes of this Paper, nor would it indeed be possible within the limits to which I must con- fine myself, to illustrate this branch of the subject at any length. It is sufficient to say, what the recollection of all wiU confinn, that, in precise proportion as we are acquainted with the details of the history of any people, we are enabled to trace the various phases of growth and decay, of prosperity and suffering, to intelligible and ascertainable causes, and to see how the laws of human nature and ' the influence of circumstances have asserted themselves against the most skilfuUy-planned attempts or the most elaborate policy. Illus- trations from ancient history might be found in the early vigour, the uniformly succeeding corruption, and the rapid fall of the Empires of the East ; in the brilliant but brief career of the Greek Republics ; and in the slow growth, the long vigorous maturity, the gradual 40 decay, and the ultimate dissolution of the Roman Empire ; but aU of these would require more detailed explanations than my time will allow me to afford. I will, therefore, select orily , one illustration, which I will take from the Jewish history, and which has appeared to me to be one of the most striking instances of the influence of circumstances as prevailing over, at once, the intentions of those who originated the movement, and the feelings and wishes of those who were the agents in its accomplishment. I refer to the causes which led to the establishment of the kingdom of Israel as a separate kingdom, and the consequences of that separation. There can, I imagine, be no doubt that Ahijah in anointing Jeroboam, and in thus preparing the way for the revolt of the ten tribes against the successor of Solomon, had in view the establishment of a kingdom, in which the pure worship of Jehovah should be maintained. The idolatry of Solomori — his introduc- tion, or public sanction, of the worship of strange gods, had been the causes why the kingdom ihat his father had founded, or rather consolidated, was to be broken up ; and it might naturally be supposed, and was no doubt confidently anticipated, that, with such an example before him, the man who was selected by the prophet of Jehovah, speaking in his name, to rule over the separated people, would have established and maintained a pure worship ; which his successors would have preserved as their best inheritance and their surest safeguard. We may, moreover, reasonably presume that Jeroboam himself was known as a sincere worshipper of Jehovah, and as one who had, privately at least, pro- tested against the melancholy defection of Solomon from the faith of his youth and his early manhood. And yet, no sooner was the revolt successful, no sooner was the separation of the ten tribes coiiipleted and the kingdom of Israel established, than the inevitable jealousy of the ruler and of his people against the metropolis of the old kingdom ; the jealousy of the priests of the high places against the priests of the temple ; and the anticipations of the new king and of his advisers of the probable consequences of allowing his subjects to go up year by year to worship in the temple ; thus bringing them under the influence of associations connected with the line of David and the supremacy of Jerusalem, prevailed over every other feeling : and Jeroboam set up, with the cordial acquiescence of the whole separated nation, the golden calves at Bethel and at Dan, and presented them to his people as representatives of the Elohim who brought them up from the land of Egypt. Nor was this feeling confined to him ; for when, at a later period, under Ahab, the wor- 41 «liip of the sanguinary and obscene deities of the Phoenicians was introduced, and the struggle between the servants of Jehovah and the partizans of the idolatrous worship culminated in the massacre of the priests of Baal in the deep clefts of the Kishon, and in the anointing of Jehu to be king of Israel ; the latter, although receiving his commission from a prophet of Jehovah, and although he quenched the fires of the altars of Baal in the blood of their priests, and des- troyed or suppressed every manifestation of foreign idolatry, was impelled by the same motives or coerced by the same influences that operated upon Jeroboam, to maintain the worship which Jeroboam had established. And thus the result of a measure which had for its object to found a kingdom dependent upon Jehovah, and in which Jehovah should be peculiarly worshipped, led to the almost entire apostacy of the majority of the Jewish people, and to their ultimate absorption into the population of the kingdoms into which they were carried captive. And this happened as the natural result of the instinct of self-preservation, the feelings of national and priestly rivalry, and the dictates of policy, necessarily springing out of the position in which the new kingdom was placed. It must not, however, be forgotten that other consequences of this division have been of the highest importance to the history of the world. It separated the kiagdom of Judah from those countries whose alliance had been most injurious to the religion of the nation — it rendered impossible those projects of forming a kingdom which by its intrinsic strength might maintain itself against the monarchies of Assyria or Egypt, which the successors of David would otherwise have entertained — it cut oflF the channels of the commerce which, under Solomon, was sapping the foundation of the Hebrew nation- ality — and it therefore cleared the ground for that complete religious reform or development, under whichever aspect it may be viewed, which characterized the reigns of Hezekiah and of Josiah; and which, finding its fullest expression in the writings of the prophets, enabled a portion of the exiled Jews to maintain their unity and their faith in the land of their captivity, and through the stormy times that intervened between the return from exile and the birth of our Saviour. Had the kingdom which David left been continued, it can scarcely be doubted, from the conduct of Solomon, and the subsequent history of the kingdom of Israel, that its great worldly prosperity and the necessary blendiag of foreign elements with the Jewish nationality, would have destroyed the essential peculiarities of the character and religion of the Jews. And if this had been the case, they too would have passed away, as so many nations more nu- merous, powerful, and united than they have done. 42 In modem history tlie instances are scarcely less striking. The decay of Spain, as contrasted with the prosperity of Holland — ^the fatal divisions which have hitherto prevented Italy from ranking as a nation — the loss of the American Colonies by England — the French Revolution — and last, but not least instructive, the disruption of the United States of America^aU are so many illustrations of the operation of causes which we can trace in the character, conduct, and circumstances of each nation. And, in fact, owing to our more intimate acquaintance with, the events of modem history, we are able to follow that operation into more minute details, and to see that it applies not only to the broad general facts of history, but also to the separate incidents of which these genei-al facts are com- posed. This is not, of course, suggested as a scientific demonstration of the fact that aU events in history are due to the operation of natural causes working in a definite direction and producing certain results — ^nor even as a complete enumeration of facts from which such an inference might be deduced. I have rather proceeded upon the assumption that the conduct, and consequently the fate, of nations is determined by the character of the individuals of whom it is composed, of course according to the degree of efiective power which they possess ; and by the circumstances in which they are placed ; and I have referred to these few familiar instances not by way of proof but of illustra- tion. And I anticipate no dissent from this assumption, whatever may be the view taken of the actual bearing of any of the examples to which I have referred. Possibly, in fact, I might have spared all illustration, and have proceeded upon the supposition not merely that the general conclusion would be admitted, but that it did not need any reference to particular instances in which its tendencies were exemplified. But even if superfluous, I trust that the manner in which I have attempted to Ulustrate the subject will not be found altogether uninteresting. Proceeding, then, upon the basis of this assumption, we have to consider whether we can take a further step, and ascertain, in the first place, what it is that determines the character of a people. And here we enter upon a question upon which very wide difierences of opinion exist. The question may perhaps be thus stated — Is human nature, so to speak, a constant quantity ; so that if any people, whatever their organizationprovided they are men, are placed in given circumstances of soil, climate, and aspects of nature, we may expect them to be similarly affected by these, and to develop a corresponding civilization ; or, do different races so vary as that, if they could be 43 placed in the same circumstances in all respects, so far as regarded soil, climate, and aspects of nature, they would nevertheless manifest a different degree and character of civilization, or might never attain any civilization whatever ? This question has received various answers ; and many eminent men — among whom I may mention two of a past generation, Locke and Turgot, quoted by Mr. Buckle, and two of the most profound thinkers of the present time, Mr. Buckle and, if I mistake not, Mr. John Stuart Mill — support the former view. Nor can it be denied that there are many very powerful arguments in support of that conclusion. The effect of these ex- ternal circumstances to which I have referred is unquestionably immense ; and it appears to be established beyond all reasonable doubt that, if two divisions of the same people could be separated from each other, and placed, the one, for instance, in such a country as Greece, and the other in such a country as Bengal, their develop- ment must take different du-ections ; and theii- ultimate character, when they had grown up into nations, must differ very widely from each other. In fact, it , may almost be considered as proved that this experiment has been made. The analogies of the Greek and the Sanskrit languages have led all who have studied the subject to conclude that the ruling class in Hindostan, and the Greeks, were two branches of the same family, who were not separated untU they had reached a certain amount of civilization : so that the wide dif- ferences which existed between the development of the Greeks and of the Hindoos — ^between their modes of thought, form of govern- ment, religious ideas, and philosophical spirit — must be due to the influence of the circumstances in which they were respectively placed. And if we were to suppose two colonies of Englishmen, the one placed in a land like that which we inhabit, where everything is to be procured as the result of labour, and where the productive powers of nature are rather deficient than excessive, and the other placed in the vaUey of the Amazon, where little labour is required, and where the powers of nature operate with such in- tensity as to dwarf by comparison the results of the labour of man ; and if we further suppose both shut out from communication with other countries, so that their development should depend entirely upon themselves and upon the circumstances by which they were surrounded, we could scarcely doubt that at the end of a few cen- turies the actual character of the two commimities must be widely different. And not only is there this ground for assuming that a dif- ference would be produced between members of the same family u as a result of their being placed in different circumstances, but there is also the seeming fact, that, when individuals of different families of the human race are brought under the same influences, their character is what we might predict from the known operation of these influences, unmodified by the influence of race. For instance, few topics have been more insisted upon by modern writers than the essential difference in organization and character between the Celtic and the Teutonic races. Innumerable events in history are referred to this difference as their cause, and the political and social position of Ireland, and of France — the two great representatives of Celtic nationality at the present day — has been explained on this assumption. Now, it is said, not merely that the character of these nations, and especially of France, has undergone great changes con- sequent upon changes in their constitution and government, but also that, if individuals of either nation became citizens of other countries, under circumstances which expose their children freely to the same influences which operate upon the other inhabitants of their new country, there is no perceptible difference in their character. It is not, of course, denied that if the French, for instance, form a separate establishment, like that formed by the Huguenot Refugees in Spital- fields, or the Irish, like those which they have formed in many of the principal cities of Great Britain and the United States, that they may for an indefinite period continue to manifest perceptible traces of their original character ; but it is said this is due to the effect, not of race, but of education, meaning by this, the sum of all the external influences which contribute to form the chai'acter. And in support of this view may be instanced the Lefevres, the Eomillys, and many others of Celtic descent both in England and the United States, who, it is said, are now in all respects as thoroughly English or American as though they had been Anglo- Saxon by descent instead of by adoption. Without pretending to give an opinion upon this branch of the question, so far as the dif- ference between the Celtic and Teutonic races are concerned, I would suggest two considerations which appear to me to render these assumed facts of little value in determining the general enquiry. In the first place the same reasoning which led to the conclusion that the Greeks and the Hindoos were branches of the same family leads also to the conclusion that the Celts are another branch which separated from the original stock at some earlier epoch : in which case the difference in character might be attributable to the effect of the different circumstances in which they have been placed, and, of course, would be susceptible of obliteration by analogous causes 45 operating in a reverse order ; and, in the second place, it is a question -vvhetlier the difference between the character of the English people, and that of the other branches of the Teutonic family, may not be in some degree dependent upon the greater infusion of Celtic blood, and whether the character of the American people may not even now be in course of alteration from the same cause. Still, whatever opinions we may adopt with regard to such original differences of organization, if any, as may prevail between the different peoples who now inhabit Europe, excepting the Laplanders and their cognate races, it is very difficult for anyone who has seen the Australian and Polynesian races, to say nothing of the North American Indians and the negroes, to adopt the opinion of Mr. Buckle when he says, " The child born in a civilized land is not likely, as such, to be superior to one bom among barbarians ; and the difference which ensues between the acts of the two children will be caused, so far as we know, solely by the pressure of external circumstances, by which I mean the surrounding opinions, knowledge, associations — in a word, the entire mental atmosphere in which the two children are respectively nurtured." That a child of European parents born among'the native Australians, and, from the moment of his birth, separated from its parents, and brought up among those natives ex- clusively, never seeing any other practices or hearing any other sentiments than those of the tribe among which he grew up, would show no marks of superiority either intellectual or moral, is possible ; though it is also possible, and, I am inclined to think, probable, that he would be their superior in intellect and energy ; but that the chUd of natives of this country, brought up in England, and never hearing or learning anything but what English children hear and leam, woiJd be undistinguishable, mentally and morally, from an Englishman, is a proposition which I confess I greatly doubt. It is easy to repress tendencies and to dwarf growth, but not so easy to infuse tendencies which are not proper to the organization or to increase the growth beyond certain well-defined limits. It is said that the Chinese have an art of growing oaks in flower-pots, so that the mature tree should not be larger than a cabbage ; and this, by withholding the appro- priate nourishment and constantly repressing the growth, is con- ceivable ; but I never heard of any people persuading a cabbage to grow to the size of an oak. And, taking a general survey of history, it appears to me there are innumerable facts that point to the same conclusion. Thus, in many coimtries in the old world, the actually civilized race by which 46 we find them to have been inhabited within the historical period was not the earliest possessor of the soil, but dispossessed some anterior occupants who had never raised themselves above bar- barism ; and in many of the countries which were once civilized, and whose soil and climate and aspects of nature remain the same, the new conquering race, although it had the example of anterior civilization by which to profit, has not in fact ever raised itself abovfe its original condition. In the new world, too, it is true that we find the two comparatively-civilized empires of Mexico and Peru grown up just where the theory of Mr. Buckle would require that they should ; and yet we see, in the more temperate parts of North America, the Indian himting over plains dotted with mounds marking the sites where once stood large cities, and where the material elements and incentives to civUiiation lie as ready to his hand as they did to those of the extinct population by whom these mounds were erected, without any attempt to elevate himself above his existing condition, and without even the curiosity to enquire how these mounds were formed. It would seem, too, that the view which regards difierences of race as important elements in the formation of character is war- ranted by the analogies of nature. Making every allowance for the power of adaptation among animals, by which they are, to a certain extent, enabled to accommodate themselves to new con- ditions of life, it is manifest that their habits and instincts, their mode of hfe, their food, and their methods of obtaining it, are dependent upon or intimately correlated with their organization, and that, for the most part, any change in the former must be accompanied by a corresponding change in the latter, if the animal is to sin:vive. And as man is certainly an animal, though with faculties, powers, and feelings which no other animal possesses, there is a strong ground in reason for supposing that those faculties, powers, and feelings, if not directly dependent upon, yet would be found to be correlated with his physical organization. And when we find that, ia fact, there are gradations of form and structure in the races of man, from the Australian negro up to the Caucasian — ^to employ a much-abused term — and that, for the most part, if not uni- versally, these gradations in organization are associated with and indicate corresponding gradations in actual progress, if not in in- herent capacity, there seems to be all the proof which the nature of the case admits, that the two are in some degree agsoeiated as cause and effect ; though we may be very far at the present ti,me from knowing the nature of the connection or the mode of its operation. 47 And this conclusion appears to me to be strengthened by the analogous phenomena which we observe with regard to individuals. There is in them the same variation in organization and the same difference, in mental capacities and in moral character. And there appear to be the same general grounds for supposing that the one class of phenomena is dependent upon the other. Upon the whole, therefore, I have arrived at the conclusion that difference of race is one of the elements which enter into the formation of the character of nations; and aid in determining the course of their history. It must, however, be confessed that this conclusion, if true, leads us a very little way, for, of all matters, those of which we know least are perhaps the causes which determine the varieties of organization of the human famUy, whether as regards individuals or races. We must, for the present, accept the existence of these varieties as an ultimate fact. That such differences do exist is undeniable — that they are connected with, and are the causes of, mental and moral differences, I think that I have shown to be probable : but further than this we are at present unable to penetrate. The only conclu- sions I can here venture to draw are, that any laws, deduced from the observed effects of external causes upon the races which have actually become civilized, are not necessarily nor even probably applicable to other races ; and that it is at the least presumable that some of the observed differences in different civilizations are due to difference of race, instead of being due entirely to the operation of the circumstances in which a nation has been placed. In analyzing, then, and defining the physical and mental laws which favour the growth of civilization and determine its character, we have to bear in mind that their result is not an absolute quantity, but one which varies in some unknown degree with the organization of the people upon whom they operate. Subject to this exception, however, ifc seems to me that the view given by Mr. Buckle in his history of civilization in England of the circumstances which render civilization possible, and which deter- mine its course, is mainly correct. He conceives the first requisite to have been a soil and climate which enabled the unskilled labour of primitive man to raise a larger portion of food than was required for the subsistence of the labourer, in order that the surplus produce might be available for the support of an unemployed class. Until this was the case, no organization beyond the rude organization of the family and the tribe, no division of employment, and no combination of labour could exist ; and, as a consequence, there could be no cre- ation of capital and none of the works which can be produced by the 48 power wliicli capital furnishes of commanding combined labour. He then shows how the character of the food which is the staple pro- duct of the various countries in which the principal civilizations of the East and of America have originated — by its cheapness and abundance, has encouraged a dense population, which has therefore been poor, and the labour of which has been at the command of the ruling class upon easy terms. And he has shown how, by the side of these, other civilizations have arisen, later in their development, because less aided by the powers of nature, where food was neither so cheap nor so plentiful, requiring more labour for a scantier return, but in which a freer scope was given for the play of the human facul- ties, and in which there were no such wide differences between the conditions of the various classes of free men as those which gave their character to the older civilizations. He shows also in what - manner those other influences, which he calls the aspects of nature, operate : how, when men feel themselves powerless beside the results of natural forces, the hurricane, the earthquake, or the volcano ; or when the fertility of nature is so exuberant, as that the results of what man does are insignificant in comparison with what' nature does for him ; or when the climate is pestilential ; certain concep- tions with regard to the objects of worship naturally arise, essentially distinguished from those which spring up in other countries, where these natural conditions are reversed. It is not, however, my purpose to pursue these investigations. It is sufficient to say that under these combined inflaences of external circumstances and of national character thus originated or modified, Mr. Buckle considers that the various early civilizations of Egypt and the East, and the later of Judea, Greece, and Rome, sprung up and obtained their separate development : and, as the result of these difierent influences, he shows that while the one kind of civilization chiefly depends upon and is to be explained by physical laws, the other, including that of modern Europe, chiefly depends upon and is to be explained by mental laws. The question then arises — What are the mental laws that regulate the progress of European civilization ? Is the guiding power the perception of moral or of inteUeotual truth ? One or the other of these it must be, since all mental laws may be classed under one of the two heads of moral or intellectual — the one relating to our duties, the other to our knowledge. To this Mr. Buckle has answered — Intellectual truth ; and the argument by which he supports this conclusion may be very briefly stated. He observes that the standard of conduct in nations is perpetually varying, and on the 49 ■wHole progressive, and he thence infers that, whatever it may be that determines conduct, must itself he variable and progressive. He then shows that the truths which are recognized as the ultimate rules in morals have been long known, and have for many centuries received no addition, and that hence it cannot be these which furnish the varying rule necessary for the purpose of the enquiry. On the contrary, intellectual truths, or what are apprehended as such, are constantly varying and constantly progressive, and hence supply such a standard as is required. He therefore concludes that the latter are proved to be the cause and measure of change and of pro- gress. In this conclusion I am disposed on the whole to concur, at any rate so far as nations are concerned. Allowing for occasions such as that of the French Revolution, and that of the war now raging, in America, where the passions become so excited as to sUence for the time aU. considerations of expediency, there can be no doubt that national action is, in the great majority of cases, if not in all, determined by a consideration of what is conceived to conduce to the national interest. And under this view it may be doubted whether even the instances to which I have just referred are excep- tions, since both of the movements originated in an instinctive feeling that the deepest national interests were involved ; and it is the nature of all powerful impulses to action to carry the agent far beyond what would be the limit fixed by a mere consideration of the object sought to be obtained. But if this is the case, then whatever tends to enlighten mankind as to their true interests — to make them feel that religious persecution, war, slavery, oppression, injustice, never in the long run accomplish even the objects for which they are undertaken or sanctioned, and that they are as injurious to the progress of a nation as they are to the happiness of individuals — must tend to render the occurrence of these scourges of the human race less frequent, and so far to improve the conduct and the cia-cum- stances of nations. At the same time, I conceive that this conclusion is stated too absolutely. I doubt if sufficient allowance is made for the different degree of force with which the same truth is appre- ciated, according to the time and circumstances in which it is pre- sented to the individual ; or for the effect of example in stimulating to virtuous conduct ; or even for the probabiKty that these intel- lectual truths, which are supposed to be the sole guide, owe no small degree of their operative force to the perception that their -dictates practically coincide with the old moral truths. No doubt, how- ever, Mr. Buckle would have been quite ready to admit all these considerations. But in a work which was intended to lay the 50 foundation of a science of history, he pursued the scientific method of making abstraction of all but one chief element, in order that its distinct and separate effects might be traced and decided, leaving the other subsidiary elements to be afterwards estimated and allowed for. There is one corollary from this view of the determining cause of human progress to which it may be usefiil to advert. Intellectual progress, and moral progress, too, so far as it depends upon the conclusions of the intellect, imply the substitution of true views for erroneous, or the elimination from partial truths of the errors which they contain. Now, it is obvious that this is impossible to anyone who is impressed with the conviction that what is received as truth is not to be questioned. To substitute a new view for an old one it is necessary that the old view should be foxmd to.be no longer tenable ; and this demands, as its previous condition, enquiry and investigation ; which again wiU not be undertaken excepting as the result of doubt. It is true that the actual course of the discovery of new truths does not always appear to take this form. They often seem to flash upon the mind "as intuitions coming we know not how or whence ; but these intuitions of new truths never come excepting to those who, consciously or unconsciously, have felt the barrenness and insufiiciency of the received beUef. Hence this conclusion follows — that doubt is the great instrument of progress, and that sceptics are among the great benefactors of the world. It ought not to be necessary to show the limitations of this state- ment, but to prevent misconception I will do so. In the first place, then, I do not regard doubt as either the necessary or the appropriate condition of the great majority of mankind. Action is the essential function of humanity, and doubt always tends to impede action. And there are few, comparatively, who have either the leisure for ori- ginal investigation or the faculties which its successful pursuit de- mands. Not many of our race have the intuitions which enable them to discover new truths, or the logical training which fits them to judge of the sufficiency or completeness of the proof which is offered in support of the old. All of us upon some topics, and most of us upon all, must take our opinions upon authority, accepting as suffi- cient proof of their correctness the general agreement among those who have investigated the subject. And, with regard to those questions in respect of which no such agreement exists, though opinions are and must be adopted by the many without enquiry, yet in these cases they, for the most part, practically adopt only such part as they feel to be suitable to their condition and wants, and more 51 or less consciously reject or modify the rest. They are benefited, consequently, by doubt and enquiry, only at second hand, when results are obtained which can be embodied in popular teaching : but they are thus benefited. And, in the second place, mere doubt, excepting for its indirect efiect of making us tolerant both of the doubts and the convictions of others, is useless. It is useful only when it has led to an enquiry which has either established some old opinion on a firmer basis, or has unseated it and substituted some- thing better in its place. But the essential condition of progress, and the proper attitude of every reasonable being, is that the intellect should be kept open to new truths or new views of truth, from what- ever quarter ; and that no enquiry should be rejected or forbidden upon the ground that the subject to which it relates is established beyond the possibility of question. In order to complete the view which I propose to take of this subject, there are still two topics to which I wish to advert, and which I shall briefly illustrate. The first is, the influence exerted upon the course of history by individual character and action j and the second, the manner in which the actual condition of the civilized world is dependent upon and moulded by all preceding civilizations. It is a complaint of the poet that " the indijyidual lessens and the mass grows more and more," and there is undoubtedly some truth itt this ; though there probably was never a time in which the mass was not liable to be swayed by common motives and to obey a common impulse ; and, even now, the influence of individual genius and energy is a perceptible power in the progress of human know- ledge and conduct. And no theory of history can be complete which does not include this influence of individuals as well as the more general causes which operate upon a people as a whole. Take a not very great number of men out of modem history, and how difierent would have been the intellectual condition of the nations of Europe. One may enumerate less than a dozen — Copernicus, Galileo, Kepler, Bacon, Descartes, Newton, Leibnitz, Flamsteed, Lagrange, Laplace. Where, without these, would the science of astronomy have been ? Without Cromwell, how different would have been the history of England ; without Napoleon, how different that of France. It is no doubt true that all of these were, in a certain sense, the product of the age— they could not have been what they were, nor have accomplished what they did, had it not been for the actual condition of the circumstances in which they were placed ; but the subsequent course of science and of history 52 would have been different had they not lived. I will select two illustrations of this effect — one from ancient and one from modern history — the one connected with the histoiy of the Jews, and the other with thai of the Roman Church. One of the most perilous times for Jewish nationality was the reign of Antiochus Epiphanes. An able, energetic, and liberal ruler, he entertained the project of establishing a united monarchy upon the principle which he had seen practised with so much success at Rome, where he had long been a hostage, of absorbing aU nation- alities in a common"- organization. In this projected kingdom he proposed to establish the policy pf Rome and the arts and philosophy of Greece. To the accomplishment of this design there was one obstacle — ^that of Judsea ; and to overcome that obstacle he put in motion the various means which were familiar with the rulers of that day, and which have not yet become entirely obsolete. He tempted the pliant by the offer of place and power ; he awed the indifferent by the display of force ; and to the malcontent he gave the alternative of submission or death. At first he was suc- cessful. The high priest was won over to the side of the monarch, and signalized his adhesion by adopting the name of Jason in place of that of Joshua ; and the majority of the priests and of the people of Jerusalem followed his example. The Temple was polluted : for a moment the statue of Olympic Jupiter was erected within its walls ; and thpugh this provoked tumults, they were put down by the troops of Antiochus. And it almost seemed at one time that the attempt would be crowned with ultimate success. In this ex- tremity, however, the members of one heroic family- — the Mac- cabees — offered themselves as leaders for the adherents of the ancient faith, rallied round them the patriotism of the nation, and organized and maintained a resistance which aU the power and policy of Antiochus were unable to overcome. It is not easy to over-estimate the consequence to the civUized world of these events. Had Antiochus succeeded, the material prosperity of Judeaa might have been much greater, but it could not have been the birthplace of Christianity : and yet but for this one family his success was all but assured. Never, perhaps, has any conflict been fraught with more momentous results. Great as were the interests involved in the battle of Marathon, where, as has been forcibly stated, the contest was whether Europe should be civilized or barbarous, they appear to me to become well nigh insignificant in comparison with that which was at stake in the almost nameless battles of the Maccabees ; for there the question was, whether the long progress of those religious 53 ideas wtich formed the iuheritance of the Jewish nation, and which found their completion and fulfilment in the work of Christ and the preaching of St. Paul, should run their course, or should be checked, and be absorbed in the civilization and philosophyof Greece. And beside the intrinsic importance of the events, I have been induced to select them because, owing to the break in Jewish history which is occasioned by our habitually passing over the period which elapsed between Malachi and John the Baptist, this is a pei'iod which seems to me scarcely to have received the attention to which it is entitled. I select now, as another illustration, the founder of the Society of Jesus — Ignatius Loyola. For though, possibly, the personal in- fluence of Luther was as great or greater, that influence displayed itself more in accordance with the obvious tendencies of the age. And though the Reformation either would not have occurred when it did, or would have run a different course had Luther never lived, yet he did not set so unmistakeable an impression of his own indi- viduality upon the movement which he originated, as did Loyola. The Society of Jesus has been, almost ever since its foundation, a power in the world ; and it has been so by maintaining the organi- zation and observing the rules prescribed in the first instance by its founder. The celebrated reply of one of its generals, vrhen urged to make some concessions for the purpose of neutralizing the hos- tility which the Society had provoked, " Sint ut sunt aut non sint," has always been the governing principle of the body ; and it shows the profound knowledge of human nature, sagacity, and de- termination of its founder, that he shoxild have thus framed a system which contained these elements of perpetuity and strength, and should have succeeded in procuring its adoption. The first results of the operations of the Society are soon told. When the Jesuits entered the field, Protestantism was everywhere in the ascendant. It had pene- trated into every country in Europe, and though opposed and pro- scribed in some, was stiU gradually working its way even in Italy and Spain, while in France it was supposed to number one third of the population. Within little more than half a century it was extin- guished in Spain and in Italy, was checked in France, and was only saved from annihilation in Germany by the intervention of Gustavus Adolphus, and at the price of the thirty years' war which reduced to a desert the most flourishing portions of the empire. And of this reaction the Jesuits were the authors and the agents. If the Refor- mation in its actual form and results was due to Luther, still more was the reaction in its actual form and results due to Loyola. 54 Of course I do not suppose that in either of these instances the individuals whom I have thus selected for the purpose of illustration could have effected vrhat they did if they had not represented and embodied an actual existing feeling and tendency. Had not the feelings of nationality and patriotism, of love for the national religion and faith in the national God, existed in the minds of the bulk of the Jewish people at the time of the Maccabees, their zeal and courage and energy would have been fruitless. But, by means of that family, these feelings were stimulated and developed ; the weak were roused, the wavering fixed, the timid encoirraged, and, what was above all essential, leaders were pro^-ided equal to the occasion, around whom all might rally, and who were able to unite the scat- tered elements of resistance into combined and mutually supporting action. And without such leaders the feelings which prompted the resistance would have evaporated in fruitless repinings, or would have wasted their strength in isolated tumults that would have been easily suppressed. And so, in the case of Loyola, the elements of the reaction were already there. The Reformation had from the first aroused the hostility of all who were interested in the ancient abuses, or were sincerely attached to the ancient faith ; and in its progress it provoked a wider opposition. It is a necessary, or at all events an universal, tendency of human nature, that no principle, hovrever pure in its character, can maintain its purity when at- tempted to be realized in practice through human instrumentality. The early history of Christianity — I might say its entire history — is a striking exemplification of this ; and assuredly the history of the Keformation formed no exception. The wildest excesses in doctrine and practipe, of which the proceedings of the Anabaptists at Munster are examples, too often disfigured the movement. Many, taking literally the precept, " The truth shaU make you free," imagined themselves freed from the restraints of law and custom, as well as from the errors of doctrine and practice against which the Refor- mation was directed. The negative character of much of the teaching of the reformers, and the logical aspect of their doctrines, were felt as unsatisfying and repugnant by the sincerely devout. And all who considered it meritorious to surrender their reason to faith, and who deemed it impious to subject the claims of the Chiirch which they had so long been taught to regard as infallible, to the same investigation which they would have allowed in the case of mere human institutions, regarded the free spirit which the Refor- mation encouraged as a mark of infidelity, or rather of atheism. But an organization was wantea to combine all these scattered 55 elements — something roucd wlaicli, so to speak, tliey might crys- tallize, and this was given by the Society of Jesus. That there would have been a reaction — that the progress of Protestantism must have been checked — -is an infel-ence that no one probably can fail to draw from the feelings which the Reformation had provoked ; but that reaction would have been very different in its character, and far less complete and durable in its results, if Loyola had not lived. I need hardly say that I do not consider this influence of the great men of every age upon their contemporaries, and the character which they thus impart to the history of their time and of future- times, as an exception to the order of nature. It is a part of that order. But I deem it not unnecessary to call attention to the fact, of this influence because, in referring to general laws, there is a tendency to ignore the freedom of human action and the infinite variety of human character, and to argue as though the laws which, in the long I'un and in the mass, are seen to regulate human affairs, and determine the course of events were inconsistent with, instead of being the exponents of, the free choice and self-determined action, of individuals. The present condition of mankind is the result of its past history.. There is scarcely any people that has lived that has not contributed something to the formation of the character of the existing genera- tion. "We ourselves have received our religion primarily from the Jews, our laws and institutions partly from our Saxon ancestors and partly from Kome, our logic and mathematics and philosophy from Greece. And each of these nations, in that which it has thus transmitted to modern times, has been indebted in part to influences derived from the nations who preceded or were contemporaiy with its history. Nor can anyone say that one of these gifts to modern society is less important or less influential than another, so far as its progress is concerned. If there are those who would depreciate the sectdar elements of our civilization as contrasted with the religious, I would request them, before they definitively pronounce their opinion, to trace out the result of all the attempts which have been made to establish a state upon « theological basis ; and, either to deduce the laws of government and the maxims of society, not from the laws of God as taught by experience, or from the example of those who had made the science of government their study, but from the Bible ; or to exclude all science as profane, and all free enquiry as ti-eason against God and an affront to the infallible rule which he has afforded, whether in the Chm-ch or in the Scriptures. They may take New England, or one party in England itself, in the time of 56 the Commonwealtli, or Geneva in the time of Calvin, as illus- trations of the one, and Paraguay or Spain as examples of the other. And, having done this, they may say whether even re- ligion itself does not gain by the admixture of those secular elements which modern Christian society has derived from Pagan sources, and from that spirit of free enquiry into the origin and grounds of all belief of which Socrates may be taken as the most signal, though very far from the only, example and teacher. For, under another form, and with a different method, which prevent its being generally recognized, the same spirit was as fully ex- emplified in Isaiah and St. Paul ; to take them as types of Hebrew and Christian teachers. In truth, both Hebrew prophecy and Christian teaching were founded upon the inalienable right of man to reject or to modify any views of truth, however sanctioned, which were found inconsistent with improved knowledge or inapplicable to existing circumstances. And whether they, to whom I am ap- pealing, admit this or not ; since they caimot be blind to the fact that these secular influences exist, and that they have modified and are even now modifying religious opinion ; they cannot but see that there are natural causes operating ,by their own intrinsic force in accordance with the laws of human nature which affect the faith and feeling and character of men — even of religious men. If acquainted, even in a small degree, with the history of controversy they wiU know how much of what is now received as Christian doc- trine is in reality the result of the application to the language of the New Testament, of the ideas of Plato, or the mystical conceptions of the schools of Alexandria, or the juridical maxims of Eome ; if altogether unlearned in this history, they may at least, if they watch the current literature of the day, see how, under the influence of secular ideas, the views even of systematic theologians have changed from those which were current only half a century ago, and are stiU in process of change. And, seeing all this, I ask them, will they retain the current view which supposes that, of many causes thus operating to produce a common effect, the one is the result of the watchful and overruling providence of God, and all the rest the result of what, under this aspect, is equivalent to chance ? WUl they believe, in opposition to St. Paid, what the current theology implies, that God was the God of the Jews only and not of the Gentiles ; or will they not rather see a proof in aU this, that the laws which God has ordained; which rule the conduct of men no less than the forces of nature ; which, being framed by infinite wisdom, can find no emer- gency unprovided for, no contingency overlooked ; which, being 57 the representative to us^ of a Being in whom is no Yariabloness, cannot admit of change ; of a Being almighty, cannot allow of violation ; have been operative in all times of history and in all countries which have been peopled by man ? Law, under this aspect, is not the antithesis but the manifestation of will, and since that win is the will of a Being perfect in wisdom, knowledge, power, and goodness — the same yesterday, to-day, and for ever — all its operations, rightly interpreted, will manifest these attributes of its author. SCIENCE AND THEOLOGY. I PKOCEED on the present occasion to attempt to redeem my promise to read a Paper on the relations between Science and Theology ; but I confess that I have entered upon the task with much reluc- tance. The subject is one of great intrinsic difficulty, and it is not easy so to speak as to avoid misconstruction ; nor do I feel that I am competent adequately to deal with it. Still, the topic is not merely interesting, especially at the present moment, but it possesses a close practical relation to the great majority of the subjects which from time to time occupy our attention as members of this Society. Every scientific investigation, whether physical, physiological, or historical, runs up into regions which have been at one time or another monopolized by theology ; and it is consequently almost a matter of necessity that the respective claims of the two should be adjusted. Whether this can be satisfactorily accomplished may be doubted ; or rather, it is quite certain that no present adjust- ment is practicable, which shall secure freedom to the enquiries of science and at the same time preserve the peace of the theo- logian. It may be permitted, however, to investigate the nature of their relations, and the points in which they apparently conflict, in the hope that something towards the solution of the question may be accomplished in this case as in so many others, by an attempt to exhibit in calm and unexaggerated language what the question really is. It can, I imagine, scarcely be doubted at the present time, that in many particulars the cqjjclusions of modern science conflict with the dogmas of theology ; and even if it were possible to dissemble the fact of this contradiction, either by denying the conclusions of science, or by modifying the theological dogma so as to bring the two into apparent juxtaposition, yet there would still remain an ab- solute difference between the theological and the scientific basis and method as they are at present understood. Theology rests upon 59 authority : science upon investigation. Theology is always based upon a revelation either universal or special : science upon reason. Theology presupposes the absolute insufficiency of the human facul- ties : science their relative sufficiency. Theology proceeds from certain facts or principles which are held to be above all need of proof, and to be exempt from investigation : while science assumes nothing excepting by way of hypothesis and conditionally, accepts nothing as true excepting upon the appropriate evidence, and re- gards no assertion as raised above investigation. Even, therefore, when the conclusions of the theologian and of the philosopher coincide, they rest upon diiferent foundations and have been attained by a different process. And yet it would appear, a priori, that there need not be any such conflict : for the appropriate domain of theology lies altogether beyond or at any rate apart fi-om that of science, and those ultimate truths upon which theology pronounces so absolutely are truths which science confesses itself without instruments either to prove or to confute. What is the origin, and what the essence of mind or of matter — what the cause and principle of the forces which per- vade nature — what the essential being and attributes of God — what the ulterior destiny of man — these are questions which science, properly understood, can scarcely propound to itself, and which, when proposed, are by their terms beyond the reach of a scientific solution. Some of them, no doubt, are not beyond the reach of analogical conjecture ; but, as these conjectures have no basis of certainty, and are beyond the possibility of verification, they cannot pass into the domain of science. They may raise a faint presumption in favour of one set of views or against another, but that is all. And thus there cannot be properly, and there is not, I imagine, in fact, any opposition between science and theology upon these essen- tially theological subjects. It may even be said that science, by the very limitations which it confesses, and the contradictions in which it is involved when it attempts to pass these limits and to speculate upon subjects which transcend its sphere, bears unconscious testimony to the central truths of theology ; that there exists a great first cause from which proceed every thing that we see and all that we are, and that this cause is unsearchable and past finding out. No doubt this tes- timony is, under most of its aspects, rather negative than positive, and under every aspect imperfect. But it is not therefore the less valid, so far as it extends. In every direction in which our en- quii'ies are prosecuted, we find ourselves encountered by insoluble 60 mysteries. We are absolutely unable to conceive the possibility either of the origination of matter or of its eternal existence, and yet are of necessity compelled to conclude that one or the other of these must have been the case ; and similar difficulties surroimd the question of the cause and origin of spirit. We cannot conceivp of force as an essential attribute of matter, and yet cannot conceive of matter otherwise than as possessing force, for matter is incon- ceivable without resistance, and resistance is a manifestation of force. And these are only samples of the contradictions in which we are involved when we attempt to form any conception of "things in themselves." But, then, the very impossibility of any solution derived from our own faculties appears to involve the idea of some- thing, or rather of some being, the cause and t\e reason of all existence, in whom all these seeming contradictions are harmonized, but whose nature and essence are on that very account inscrutable to our imperfect conceptions. And when we see how a few elementary substances, manifesting or acted upon by various forms of force, result in all the variety and order and beauty of organic and inorganic nature — how every part is dependent upon and adjusted to the whole, as the whole is adjusted to the various parts — how all creatures, from the lowest to the highest, are adapted to their circumstances, and all apparently exhibit a marked pre- ponderance of enjoyment — we cannot, as it appears to me, do other- wise than regard all these phenomena as so many manifestations, relative to our faculties, of the wisdom and goodness of the Being to whom they are owing ; though we still confess our inability to conceive of Him as he is. And further, although, as I have attempted to show in my pre- vious Papers, everything around us, everything that science dis- closes of the past or can conjecture of the ftiture, displays the same obedience to law — although nothing in nature warrants the as- sumption that there have been emergencies which infinite wisdom had failed to foresee in the adjustment of these laws, or against which infinite power had been unable to provide, and in which, therefore, some suspension or violation of law was needed in order to prevent or to remedy disorder — yet there is nothing in this con- ception which contradicts the theological idea of a personal God, or excludes the notion that he works in aU things according to his wiU. Impossible as it is for us to think of absolute being as per- sonal, or to predicate of it such an attribute as that of will, yet these difficulties are metaphysical, not scientific. So far as science is concerned, there is nothing in the conception of causatiojj^'mat 61 necessarily contradicts personality — nothiing in the universality of law wliicli excludes will. On the contrary, knowing that with men, the higher their moral and intellectual faculties the more nearly do they approach to consistency, and the more rarely do they manifest anomalies and imperfections, we are naturally, if not necessarily, led to regard this connection as essential, and to suppose that in propor- tion J;o the wisdom, goodness, and power which any being possesses will be the uniformity of the procedure in which his will is manifested. And hence, assuming the absolute wisdom, power, and goodness of God, we should deduce from that assumption an absolute uniformity in the processes of nature and the dealings of providence, supposing that these are the results of his will. No doubt, to those who place God outside of nature, and conceive of him as in some respect an- tagonistic to it, this view of the universality of law is repugnant, because it appears to exclude God from the universe. So far from this being the case, however, it negatives the idea of the occasional intervention of the Deity only because it regards him as always and everywhere present and active. It is not, therefore, upon any of these great truths which underlie all theology, that the oppositions to which I have referred arise. The questions which are now at issue between men of science and theologians stand upon another and a lower ground. They are, for the most part, reducible to one, or, rather, they are different aspects of the same fundamental question : — ^what, in matters of science, meaning by this everything which the human intellect is competent to investigate, is the authority of the Hebrew and Christian Scrip- tures ? Either directly or incidentally these writings contain no- tices, or descriptions, or narratives, which refer to matters susceptible of investigation, and which are more or less at variance with the results of scientific enquiry. And, as the first consequence of the perception of these variances was the denial of the conclusions at which men of science had arrived and a condemnation of the method of enquiry which had led to these obnoxious conclusions, it followed necessarily that those who had proved the soundness of their method of investigation in a hundred fields of research, and who could not, without renouncing the exercise of their reason, doubt the truth of the conclusions at which they had arrived, were drawn to examine their position in reference to the Bible. This examination took at first the form — Is the teaching of science in these matters, especially in geology, at variance with the teaching of the Bible ? In this enquiry many persons, among whom I may name Granville Penn, Chalmers, Buckland, Pye Smith, Hugh MiUer, proposed various 62 methods ofreconciling the apparent discrepancy — some by moulding the facts of science so as to make them harmonize with the language of the Bible, and some by moulding the language of the Bible so as to make it harmonize with the facts of science. But as all of these, however decided and however sincere their professions of belief in the inspiration and infallibility of the Bible, virtually conceded by the very attempt at reconciliation that, in matters of science, science was the ultimate authority, a farther question necessarily was raised : Is the Bible to be regarded as infallible in matters of science ? And this latter question became connected with others which resulted from contemporaneous investigations into the origin of the Bible itself, and which concerned the date, authorship, authenticity, and genuineness of the various books of which it is composed. And aU these questions have gradually been investigated with more boldness and earnestness as their importance to the interests both of science and of religion has been more appreciated, and as the materials for forming a conclusion have become more abundant and accessible. The question, therefore, between science and theology has a two- fold aspect. It regards, on the one hand, the facts narrated in the Bible — its cosmogony, chronology, ethnology, and history, and examines into their accordance with the laws of nature, and with the inferences derived from a complete induction of known fects. And, on the other hand, it regards the origin of the Bible itself — at what time, by what authors, under what circumstances, were its various books written. And under each of these aspects science comes into collision with theology. Theologians assume that these books are the direct utterance of the Supreme Being, and that whatever is therein narrated must not only be received as literally true, but must, if needs be in order to its reception, be considered as with- drawn from the operation of the ordinary laws of nature, and as being in the strictest sense miraculous ; and this, if admitted, would be fatal to the pretensions of science. It is true that, in deference to the opinions of the day, from the influence of which no man can wholly escape, there has been on the part of many theologians a recession from these extreme pretensions ; but this is at variance with the theological spirit, and those who have made such conces- sions are often regaijded as only a shade less dangerous than those who frankly adopt the scientific method throughout. This, then, is the theatre of conflict, and the question is whether science in its enquiries upon these subjects has invaded the domain of theology, or theology, in attempting to exclude them from investigation, has intruded into that of science. 63 It cannot, of course, be pretended that the great majority of these subjects, relating, as they do, to results of physicial agencies, and to human conduct, are not in themselves properly the subject of scientific investigation. Whether, for instance, at any time within the last 4,000 or 5,000year3the whole of the earth has been covered with water to the depth of some miles, and for a period of many months, is a question of the effect of physical agents, and properly to be investigated by the methods of physical enquiry. Whether a book, such, for instance, as Genesis, appears to be the production of one individual, or of more than one — whether it exhibits a unity of conception and of execution — whether the language is all of one age or in parts of different ages, and to what age the language is to be referred — and whether the date of the composition, in whole or in part, can be approximately fixed by a consideration of the pecu- liarities of the language, or of other internal evidence — are questions of crititism, and are prima facie to be decided by the same canons as are applicable to other ancient writings. Whether a particular people belonged to one branch of the human family or to another is a question of ethnology, and to be decided by considerations of their language, institutions, and history. Whether events are probable or the reverse, and whether the evidence of their having actually occurred is of such a nature as to overbear any antecedent presumption against them on the ground of their improbability, is a question of evidence, and to be decided by the same principles as would guide us in investigating any contemporary narrative. At least, this must be the case, unless some reason can be shown for applying different methods and tests to the investigation of the books of the Bible and the events therein narrated from those which would be applied to other books and events. There is, however, a widely-spread feeling that the Bible and everything that it contains ought to be exempted from enquiry. Apart from those, aad they are many, who think that the teachings of the Bible are to be taken as conclusive upon all subjects, and that it is impious to enquire, when, as they conceive, God has spoken, because enquiry implies a doubt either of his knowledge or of his truth, there are many who would willingly ignore all these topics. They admit the right and the competence of the human intellect to prosecute such enquii-ies, but they fear, possibly, that the results may tend to weaken their own faith, or, at any rate, to weaken the faith of the multitude. Both of these classes are entitled to much consideration, but neither of them has a place within the walls of this room. The very object of this Society is to investigate the 64 laws of nature, in their practical and in their speculative aspects, and this implies, necessarily, the absence of all bias and of all limit. In other societies, philosophical or scientific investigations may be followed only to a certain distance, and always with a tacit regard to consequences. Here we have no object but truth, and no limit but that which results from the necessarily progressive character of all knowledge. In fact, it is obvious that any such limits as theology would impose are inconsistent with all enquiry. In geo- logy we should have to stop with the last division of the recent period, because that may possibly, with a little management, be brought within, or nearly within, the received chronology, and must exclude from our investigations everything beyond. In ethnology, we should have to limit our enquiries to the mere classification of the existing varieties of the human family, "without venturing to speculate upon their origin and affinities, because these speculations must, or, at any rate, may result either in attributing an antiquity to the human race far beyond that warranted by Genesis, or in as- suming an original diversity of races. In the science of language we should have to shut our eyes to the evidences lying before us of the existence, so to speak, of one stratum of language underlying another, because, tracing these downwards, we may, in the dim dis- tance of an unknown antiquity, far beyond the records of history or ■the dawn of tradition, faintly surmise some original language spoken by our primeval fathers, from which all existing languages have been ■derived by natural processes. In history, we should have to leave •out of our investigations the origin, course, and results of the two most pregnant facts in the development of our race — ^the Jewish and Christian religions. I might extend the list of these limitations indefinitely, but these are enough to show how narrow would be the range, or, rather, how impossible would be the prosecution, of philo- sophical investigation if we should really determine to avoid all those points in which the Bible and science may come into collision. It may however be said, granting all this, the investigations of science should be conducted apart. Philosophers may pursue their speculations and form their conclusions, but they have no right to Taring these conclusions into comparison with the dogmas of theo- logy. This is the task and the function of theologians only, and therefore all such enquiries as the present are beyond the legitimate objects of a philosophical society. There might be some fairness in such a suggestion if men of science were left to pursue their en- quii'ies without encountering opposition or obloquy from the men of theology, but even then it would be alike unwise and impracti- 65 cable. For, in the first place, why should science be condemned to be irreligious ? There can surely be no reason why the man who before all others is familiar with proofs of the marvellous adaptations of nature — ^who sees above, around, and within him evidences of wisdom and benevolence which increase with every increase of his knowledge, should be compelled to exclude from his consideration all the lessons which he may thence derive. It has been too often, though unjustly, the complaint against science that it is irreligious ; but this would be to compel it to remain so in the supposed in- terests of religion itself. And, in the second place, it must be remembered that after all members of philosophical societies are men, and as such are as much interested in theology as anyone can be. It is for us individually as important, to know whether there is or is not any conflict between science and theology as it is for the man who repudiates all science as profane. We do not drop our personality when we enter this room, nor are we able to draw a sharp line of demarcation between our scientific and theo- logical belief, much less to assume the same thing to be a theological truth and a scientific error. Whatever may be our creed, it is the same person who believes and who investigates ; and it is therefore our right as enquirers, if it is not also our duty, to attempt to ascer- tain the relations between our faith and our science. That there is such a duty, whether it devolves upon us or not, must be taken to be admitted, for otherwise it would be impossible to account for the large and increasing number of works professedly devoted to this subject. It must, however, be confessed that there appears something of inconsistency in the manner in which these questions are treated by different persons who have discussed them from the theological point of view, and even by the same person at different times. Sometimes what, for the sake of distinctness, I may call the orthodox view, is supported by arguments appropriate to the subjects of enquiry, regarded under their scientific aspect, while sometimes the application of similar arguments to the deter- mination of the same questions is denounced as irreverent, if not impious. It would reaUy seem that the true solution of these ap- parent inconsistencies is to be found in the assumption, that the scientific method is permissible in reference to questions of theology only when it is employed to establish the truth of the received opinions, and in no wise when it is employed simply to investigate whether they are true or not. I do not suppose that in fact the majority of orthodox writers have consciously represented their own principles to themselves under this definite formula, but it is diificult 66 not to imagine that some such feeling is more or less unconsciously underlying all their conceptions on the subject ; and there are some who undisguisedly avow their adhesion to this rule. It is, however, obvious that all arguments addressed to the reason presuppose that reason is the ultimate judge of the truth of the con- clusions to which these arguments are designed to lead, and it would seem equally obvious that any claim to authority which shall exclude the employment of the reason in reference to any particular subject must, in the first instance, vindicate itself by arguments addressed to the reason. However much we may be disposed to concede to authority when its claims are established, it wotdd seem to be un- questionable that the establishment of these claims is a necessary preliminary to our submission, and that this must, or rather should be (for often it is not) the result of arguments addressed to the reason. Whatever form, therefore, the argument may assume, whether the truth and divine authorship of the Bible are attempted to be proved inductively from an examination of its contents, and from the characters of the persons by whom it was written and the miracles by which it is alleged to have been authenticated, or whether the truth of everything it contains is established deductively upon the basis of its divine authorship, the appeal is ultimately made to the human reason ; in the one case as to the validity of the induction, and in the other as to the truth of the assumed basis. And if the reason of each man is to be for himself the ultimate judge of the conclusions he shall adopt, then those conclusions must be tested by the same methods, and the evidence adduced in their support must be subjected to the same processes of examination as are applicable to all other questions. There is probably nothing in this which would not receive the formal assent of all Protestant theologians, since the very right to protest against the doctrines and the practices of the older Church must be founded upon, or, at any rate, can only be justified by, the right of private judgment — that is, the ultimate supremacy of the human reason — with regard both to the grounds and the objects of belief. It too often happens, however, that the supremacy thus conceded in theory is denied in practice, and men are permitted to enquire and examine only upon the tacit condition that they shall arrive at certain predetermined results. But this is an inconsis- tency which by no means derogates from the soundness or value of the admitted principle. Taking it, then , to be admitted, at least in this room, that there is a right of enquiry into the grounds of theological belief, both as re- 67 gards the authority of the Bible and the conclusions to be drawn from its teaching, and knowing that there are many persons who have, as the result of such enquiry, arrived at the conclusion that the Bible is not only inspired but also absolutely authoritative upon all subjects, it is not, perhaps, irrelevant to remark that any inferences to be deduced fi-om this conclusion must partake of the uncertainty of the conclusion itself, as well as of the added uncertainty of the reasoning by which the inference is reached. It would often appear as if, by a natural confusion of ideas, men upon this subject transfer the attribute of infallibility which, as the result of their investiga- tion, or sometimes prior to all investigation, they attribute to the Bible, to the process or act by which the conclusion has been reached, and thus not merely conclude that the Bible is infallible but that they are infallible in making that conclusion. In fact, however, it is only necessary to state the proposition in order to secure its re- ception, viz., that whether, in point of fact, the Bible be or be not infallible, our conclusion that it is so, being simply the result of our own mental processes, has no greater certainty than belongs to other conclusions arrived at by similar processes. The stream cannot rise above its fount. There can be no infallible conclusions of fallible reason, and therefore the assertion of the infallibility of the Bible being only a deduction of reason, cannot logically be used to bar any course of enquiry or to prove, a priori, the unsoundness of any conclusions to which that enquiry may lead. And, as has been well shown by Archbishop Whately, in reference to another subject, it is impossible to escape this dilemma. Whether a man siirrenders his reason to the Bible, or to the Church, or to a priest, or to the witness of the spirit within, and however complete the surrender or abnegation of reason may be, there is one exercise of reason which he cannot escape — -he must decide what shall be the authority to which his reason shall be subservient, and that choice must be determined explicitly or implicitly by his reason. As a late writer has said, to attempt to avoid being ultimately de- cided by reason in choosing a faith is like a man attempting to jump off his own shadow ; and thus the uncertainty which attaches to all processes of argument necessarily attaches to the decision in favour of this or that authority. Any conclusion, consequently, formed upon the basis of any authority has necessarily no greater validity than the act of reason by which that authority was recognized. I have said this because it appears to me that many persons con- ceive, either that there is something in the fact that theology has claimed any subjects as being within its domain, which renders the 68 human reason incapable of forming a judgment upon them ; or that there is a peculiar certainty in the conclusions which may be formed or accepted by the human reason in relation to them. And, sin- gular as it may appear, it often happens that these two somewhat contradictory conceptions are held by the same person, who thus both denies the competency of his reason to form an opinion, and asserts the absolute truth of the opinions which, as he alleges in the absence of his reason, he has adopted. And I have therefore attempted to show that, on the contrary, the points upon which scientific investigation is now exercised are matters especially within the domain of science ; and that every opinion which may be formed on the subject is an opinion which, in the nature of things, must rest upon individual reason, and consequently can at any rate have no greater certainty than belongs to conclusions of reason in general. I might, if it were necessary, go even further and say that, from the nature of the subject, there is necessarily a smaller amount of certainty attaching to theological conclusions than to conclusions upon any other subject, because, in addition to the difficulties which are common to those subjects and to theology, there are added diffi- culties arising from the very nature of the objects of theological in- vestigation. And, in support of this view, I might quote largely from Mr. Mansel, whose new defence of the faith excited so much attention a short time since, and having answered its end of puzzling some and amusing others, is gradually sinking out of notice. But I refrain from dwelling upon this view of the subject, which is be- sides immaterial under that aspect of the question which I am con- sidering, and content myself with remarking that these admitted difficulties may at least serve to inspire theologians with reserve and diffidence in stating their conclusions, and with some consideration for those who, upon matters so important and so difficult, may have arrived at views difierent from their own ; even though this should appear to admit the possibility that their own views were not abso- lutely complete and accurate. But if, in fact, it is competent to anyone to investigate the age, authorship, and authenticity of the various books of which the Bible is composed, to examine upon independent grounds the historical truth of the narratives which it contains, and to pursue the study of sciences, though their conclusions may conflict with the plain language of the Bible — ^then it would seem that no theological con- siderations ought to be allowed to influence the course of enquiry or to affect its result. A scientific investigation is utterly worthless imless it is absolutely unbiassed. And, if so, it. would appear further 69 that no real theological principle can be involved in the enquiry. For instance, the uniform course of opinion during the last half century among all competent enquirers has been in a direction ad- verse to the historical character, at least of the early part, of the Book of Genesis. Geology has, I believe I may say, utterly exploded the notion of creation in six days as given in the first chapter, as well as the idea of a universal deluge, and it is gradually throwing back the date of the first appearance of man upon the globe to an antiquity which, according to present appearances, will ultimaitely be measured by hundreds of thousands of years. The science of language and ethnology both tend to show that the separation of the human family, if, as is probable, it was one family originally, must be thrown back for tens of thousands of years ; and that the people of Canaan, whom the Israelites drove out, belonged, no less than the Israelites themselves, to the Semitic race instead of being Hamites, while the Persians belonged to the Indo-European family instead of being, as the author of the tenth chapter of Genesis makes them, Semitic. And, at the same time, oriti^^l investigations as to the age and authorship of the book are leadia^g unmistakeably to the belief that, whoever its compiler might be, and whatever ancient documents might be embodied in it, there were, at any rate, more than two persons concerned in its authorship, the earliest of whom could not have lived much before and probably did not live after the time of David. I do not now put forward these conclusions as true, though personally I consider the evidence such as to warrant our belief of their truth, but I mention them as those conclusions to which the current of opinion is now leading, and which the ma- jority of independent thinkers who devote themselves to these enquiries will be likely to adopt. In fact, but for the theological interests supposed to be at stake and the theological passions there- fore aroused, I believe that there would at this time be no more doubt as to the general truth of the conclusions which Bishop Colenso is enouncing with regard to the uncertainty of the early history of the world and of the Jews than there is with regard to those put forth by Niebuhr as to the uncertainty of the early his- toiy of the Romans. But however this may be, it cannot be denied that among independent thinkers who have directed their enquiries to this subject the tendency is towards the conclusions which I have indicated, in spite of strong early prepossessions, and of no slight present inducements to maintain the contraiy views. Now, is it to loe supposed — ^will anyone venture to assert — ^that these views, if adopted, can affect the relation of man to God, or the purposes of 70 God to man ; that the inducements to virtue or piety -will be diminished, or that virtue and piety will be less acceptable to God ; or even that these opinions, if honestly formed and manfully pro- claimed, will be less pleasing in the eyes of the God of truth than the contrary opinions taken at second hand without enquiry, or ob- tained as the result of an enquiry whose conclusion was foredeter- mined. No doubt it is true that many opinions which we have been accustomed to hold, rather, though, upon the authority of the school- men and of Milton than of the Bible, will fall if these views ulti- mately prevail ; and those who insist upon having their theology in a systematic form may have to remodel their systems : but these are the necessary consequences, in every branch of enquiry, of the dis- covery of new truths, whenever systems have been prematurely formed. But whatever may be their results, unless we are prepared to prohibit all scientific investigation ; and though outside these walls there may be many who would do so, yet the very character of this Society is a proof that aU here would repudiate such a pro- posal ; these enquiries are demanded by the very importance and sacredness of the subject ; and, if instituted, they must be carried on with no other purpose than that of following truth whithersoever it may lead us. But there is another aspect of science, of which the previous Papers that I have read have been partial illustrations, and that is, that all things are conducted according to invariable rules, and, to use the common phraseology, through the instrumentality of second causes, which even more conflicts with the theological spirit. But apart from the question of miracles, with which I do not here intermeddle, only remarking that the evidence to prove a miracle must be strong in proportion to the exceptional character of the fact to be proved, 1 imagine there is no well-informed person (I beg pardon, I must except modern spiritualists, but excepting them) who does not admit that the course of nature is now uninterrupted, and that all results are brought about by the sUent operation of natural forces working in definite and prearranged directions, and producing, no doubt, their appointed results. The Hebrew poets regarded thunder as the voice of Jehovah, and lightning as the breath of his nostrils ; hail and snow were laid up in his storehouses to be poured forth at his will ; and, in fact, every occurrence, whether helpful or hurtful, was referred to his direct agency. We, however, see in thunder and lightning and hail the effect of electrical agencies. Even the courses of the winds and the fall of rain are found to be regulated by laws as definite as those which cause the succession 71 of day and niglxt ; and in all surrounding circumstances we are able, altogether or proximately, to refer them to their causes and to show the manner in which those causes operate. But we do not, on that account, deny the being of God, or conceive of nature as existing independently of him. We are unable, doubtless, to represent to ourselves the mode of his existence, or the character of his relation to the phenomena by which we are surrounded and the sum of which we call nature, but we look upon all manifestations of power or beauty as tokens of his presence, and we regard the laws which we are able to trace, not as hiding him from us but, as revelations of his method of government, and as enabling us, however imperfectly, to conceive of some of his attributes. And if we are to believe what reason, no less than revelation, would seem to teach, that he is the same yesterday, to-day, and for ever, then this may be presumed to have been the method of his government from the beginning. And yet whenever attempts are made to suggest the manner in which the existing order of things may have been developed by the opera- tion of laws which still subsist, there is always more or less of sus- picion attaching to the attempt, as if it were derogatory to God to show that he was not like man, and that his operations have none of those marks of weakness and i^lperfection which characterize our own. It is probable, however, that one great source of the objection felt to these views is the fact that they conflict more emphatically than even the views as to the antiquity of the human race, or as to the non-occurrence of the flood, with the Book of Genesis, and with theological deductions from it, especially as to the fall. For, if the world has existed under the same laws from the first moment of its formation; if all things have been slowly shaping themselves into fitness for the existence of higher and higher classes of being, organic and inorganic nature gradually assuming improved forms ; and if, as the culmination of the long progress, Man appeared, at first in a low animal form, but gradually elevated to higher and higher types — then the whole doctrine of the faU, as represented in eur systems of theology, and of the present degradation of our race as compared with its early elevation, and of the deterioration of ex- ternal nature as a consequence, is obviously erroneous. I may, however, venture to observe upon this point that, although this view is inconsistent with the historical truth of the narrative in Genesis, yet the idea of the fall answers to facts lying deep in the human consciousness, and to which the experience of every man will testify. The contrast between faith and practice — between 72 resolve and performance^-lietween the excellence which we are able to conceive and that which we can embody in action — ^is a real and permanent fact in the natvire of man, whatever be the language in which it is expressed or the cause to which it is to be referred. Whether we say, with St. Paid, " To will is present with me, but how to perform that which is good I know not," or with the heathen poet, " I see, and I approve the things which are better : I follow the things which are worse''— whether, with Augustine and his modern followers, we regard it as a predestined result of the sin of Adam, which was itself predestined, or, with some recent thinkers, as a proof of the growing supremacy of the human reason and con- science, an increasing knowledge of good and evil which brings with it an admiration of the former, accompanied by a consciousness of subjection to the latter, or in whatever other forms it may be repre- sented or embodied-t-iJit remains as a fact. And, consequently, no theological doctrines which are based upon its existence would seem to be affected by the result of any scientific investigation, though dogmas which rest entirely upon the form of the narrative must faU if the narrative itself is shown to be at variance with fact. There is, then, even at the present time, an opposition upon these various grounds between science and theology. And, while theology has been stationary, at any rate since the Beformation, for the same questions are agitating theologians now as were then raised, and are apparently as far from settlement as ever, science has con- tinued to advance ; and, regarding the signs of the times, it would seem destined to continue its progi-ess, unless stopped by some catastrophe such as that which overwhelmed the civilizations of Greece and Rome. For, however much it maybe distrusted or de- nounced, the obvious practical benefits which it confers upon society, and the political, intellectual, and material superiority of those countries in which its unfettered cultivation is permitted, as com- pared with those where the theological spirit is in the ascendant, are too plain and palpable to allow any doubt of its utility and value. The nations fox whom science has done and is doing so much will never wiflingly consent to dry up the so\irces of their progress by throwing impediments in the way of its further development. Whatever, consequently, may be its effects, they are inevitable, and must be accepted as necessary elements in any scheme for the future. If science stood in need of State patronage or of artificial fostering of amy kind, there might be some uncertainty as to its permanence and progress. . It needs, however, no other encouragement than to be let alone, and then its inherent attractions will secure for it a 73 crowd of ■willing votaries by whose efforts it is advanced in every direction. And whenever any obj ect requires for its accomplish- ment more than isolated individuals can perform, the results to be attained are such as to ensure the ready union of private persons or to command the support of the public. And as a result of this progress, we may expect to see every occurrence in nature and every historical record explained and accounted for by being referred either certainly or probably to natural circumstances acting in obe- dience with or in analogy to known laws. No doubt the time of the complete fulfilment of this anticipation is far distant, but every year will see some progress made towards it, and every step in the progress is an earnest and a prophecy of its ultimate realization. But, in this case, what is to be the attitude and what the function of theology ? For the last four centuries theologians have been fighting a losing battle in every country in which free thought has been permitted. They have been compelled to concede one point after another, always after having continued the defence when im- partial bye-standers could clearly discern that the point was already lost. And they have at last retired unwillingly and under protest, not seldom anathematizing those by whose labours they have been compelled to recede. And in countries in which thought has been fettered and enquiry forbidden or its results stifled, theology has been able to hold its ground only on the condition of arresting the mental progress of the nation. So that a very few years since (as late as 1857) a Spanish archbishop could denounce the whole circle of modem science, including the discoveries which have immor- talized the names of Newton, Laplace, and others as only a renewal and reproduction of errors which had been a thousand times refuted and denounced by the Church !* Might we not fancy this to be an echo of recent orthodox denunciations in England ? Are theo- logians prepared to continue a conflict in which defeat is assured if the terms of the combat are equal, or in which victory, or rather escape, is only possible on the terms of prohibiting all enquiry into the subject ? Or will they not rather recognise the fact that nature * I subjoin a translation of the passage so far as material. It occurs in a note in ■'Buckle's History of Civilization in England," vol. ii., p. 147. "Firstly, that the schools of Holland, Germany, England, and France, hostile to Catholicism, have commenced and prosecuted with the utmost zeal certain philosophical discussions, presenting them as a triumph of reason over religion, of philosophy over theology, and of materialism over spiritualism. Secondly, that these maxims are, for the most part, nothing more than the reproduction or further development of errors a thousand times refuted and condemned by a holy philosophy and by the Church, so that instead of having to con- gratulate themselves upon their progress, they should far rather blush for their retro- gression." 74 is as truly a revelation of God as any book can be : that the reason of man is a God-implanted faculty and its free exercise a sacred duty, and that, in the exercise of his reason for the purpose of discovering the laws or elucidating the phenomena of nature, man is only bringing into broader light the proofs of the wisdom and goodness of God ? This alternative is open to them, and in spite of the clamour which a few have raised, and which the many have echoed, I think there are some symptoms that no inconsiderable portion of the theologians of the present day will adopt the latter course. ' In this case the task of the theologian is marked out before him. He has two objects to keep in view. The first is to show that the essential doctrines of theology are and will remain unaffected by any scientific conclusions, to separate them from all extraneous or adventitious elements with which they may have become mingled, and to present them in their purity and simplicity ; and the second is to consecrate, so to speak, the conclusions of science by showing their harmony v/ith these essential truths and by bringing out their religious significance. The attitude which theology in Protestant countries has long since assumed with regard to astronomy may be taken as an illustration of the spirit in which this twofold task should be perfoi'med. There can be no doubt that in the first in- stance the system of Copernicus was regarded as eminently anti- theological and atheistical. It was at variance with the letter of the Bible, with the teaching of the Church, and with the doctrines of the Fathers, and, by destroying the localities in which mediaeval theology had placed its heaven and its hell, it seemed to annihilate the belief in those future rewards and punishments of which thej' were to be the theatre. But now-a-days no one, in England at least, even dreams of there being any such contradiction, and the dis- coveries of astronomy are referred to as a sort of common place for illustrations of the infinity, power, wisdom, and goodness of the Creator. It is true that more is involved, or rather, perhaps, more seems to us to be involved, in admitting the antiqidty of man — the origin of all species, including man, by development out of lower organisms — the late date and uncertain authorship of the Penta- teuch — to take only a few of the matters which are still the battle- field of science and theology. Nor do I assert or assume that these are now proved, or that ever they will be proved, at any rate, with the same absoluteness of demonstration as belongs to the dis- coveries of astronomy. But, if not proved, these opinions are held by men eminent for ability, learning, patient investigation, and a reverent spu-it, and they are winning their way into an ever widening 75 circle of disciples. They demand recognition, then, as plausible, and even as probable hypotheses ; not proved, but coming year by year nearer to proof; and as such a theologian might deal with them. And surely there are aspects under which all of these might be made to subserve the purposes of theology. I am no professional theologian, but I might, perhaps, suggest as appropriate and as sanctioned by precedent such as these. The enlarged view which they present of the period during which the divine energy and superintendence has been manifested on our globe — the confirmation which they give to the Divine wisdom and immutability in showing 'that one system of laws has prevailed from the very commencement of organization, and that system so arranged as gradually to evolve all that we now see — the manner in which instrumentalities of the most varied and seemingly unlikely kind have been employed for the education of the world and in preparing it for higher and purer teaching — these are some of the lessons which might be deduced, and which, whether or not the most appropriate or edifyingthat might be drawn, may at least suffice to show that theology need not lose anything essential, or any instrument for elevating or purifying the intellect or the character, even were these conclusions adopted. To me the opposition between science and theology has always appeared most unfortunate. The implied stigma cast upon science, by denouncing its enquiries as presumptuous and unwarranted and its conclusions as u-religious and atheistical, is injurious to the mental tone of those to whom it is addressed, and the consequent injury to theology when it is perceived, as in many cases it is, that what has been so denounced is nevertheless demonstrably true has been at least equal. If I could believe that the opposition was necessarily inherent in the nature of the two conceptions, I should have no prospect before me but on the one hand the destruction of theology or on the' other the enslavement of the human intellect, either of which I should regard as. a misfortune of almost equal magnitude ; though undoubtedly the former would be the roBre tolerable and the more hopeful condition : for man, by his very constitution, if left free, would frame a theology for himself, not, we may believe, without the guiding spirit of God, while the enslaved intellect might struggle for ages without ever raising itself to a worthy conception of its author, its nature, or its destinies. But I do not think that there is any such essential incompatibility between the two, and it appears to me, therefore, that their present conflict arises from mis- taken views on one side or the other, which a calm and dispassionate investigation may help to remove.
