THEORY OF _PHYSIOLOGICAL_ DEVELOPMENT; OR THE PRODUCTION OF VEGETABLE AND ANIMAL RACES BY NATURAL LAW.--"TELLIAMED."--PHYSIO-PHILOSOPHY.

The Theory of Development has been applied not only to explain the origin of worlds and of astral systems in the sky, but also to account for the origin of the various tribes of vegetable and animal life which exist on the earth itself. There is nothing, indeed, in any of the kingdoms of Nature that may not be included in it, since the formation of all material bodies, organic or inorganic, is supposed to be sufficiently accounted for by the sole action of Chemical or Mechanical laws. The wide range of this theory is strikingly illustrated by the words of one whose powers of observation have added some interesting discoveries to Natural History, but whose speculations on the origin of Nature resemble the distempered ravings of lunacy, rather than the mature results of philosophic thought "Physio-philosophy has to show," says Dr. Oken, "how, and in accordance indeed with what laws, the Material took its origin, and, therefore, how something took its existence from nothing. It has to portray the first periods of _the world's development from nothing_; how the elements and heavenly bodies originated; in what method, _by self-evolution_ into higher and manifold forms, they separated into minerals, became finally organic, and, in man, attained self-consciousness.... Physio-philosophy is, therefore, _the generative history of the world_; or, in general terms, the history of Creation, a name under which it was taught by the most ancient philosophers, namely, as Cosmogony. From its embracing the Universe, it is plainly the Genesis of Moses!"[37]

It will be observed that this strange speculation goes far beyond the comparatively modest conjecture of La Place. It postulates _nothing_, and undertakes to account for _everything_. In flagrant opposition to the old atheistic maxim, "Ex nihilo, nihil," it boldly affirms, "Ex nihilo, omnia." It speaks, indeed, of "laws in accordance with which the world took its origin;" but these laws must be as abstract as those of Mathematics, since they existed before matter itself; nay, more abstract, or, rather, more inconceivable still, since they existed, it would seem, even before Mind! Dr. Oken attempts to explain the production of the world from nothing by comparing it to the evolution of Arithmetical and Mathematical Science, out of the fundamental conception of _zero_! But, waiving this, we shall direct our attention to the only points in this theory which, in the existing state of speculative thought, can be held to have any practical interest in connection with our great theme.

That theory attempts to account for the production both of the FLORA and the FAUNA of the natural world by _the process of Development_ rather than by _the miracle of Creation_. It proceeds on the assumption, akin to that of Epicurus, that atoms or monads alone existed in the first instance; and that from these were derived, under the action of natural law and by a process of gradual development, all existing substances and beings, whether organic or inorganic, mineral, vegetable, or animal. "No organism has been created," says Dr. Oken, "of larger size than an infusorial point. No organism is, nor ever has one been created, which is not microscopic. Whatever is larger has not been created, but developed. Man has not been created, but developed." On this fundamental assumption the whole theory is based. But we must carefully distinguish between the Atomic Theory and the application which is here made of it. The recent discoveries of Chemistry, by which all material compounds have been decomposed into their constituent elements, amounting to little more than fifty substances, which are either the primary or the proximate bases of all existing bodies, and the marvellous transformations which these elementary principles undergo, in respect alike of form, of density, of solidity, and of magnitude, under the action of natural laws,--may serve to make it credible that there is no _a priori_ impossibility in the assumption on which the Atomic Theory depends. Had it been the will of God to call into being the various vegetable and animal races in the way of gradual evolution out of these primary monads, no enlightened Theist will presume to say that it was either impossible, or inconsistent with His wisdom to do so. It must be observed, however, that the natural analogies which have sometimes been appealed to in support of this hypothesis, labor under a grievous defect when they are applied to account for the origin of the existing races, and that they are extended far beyond their legitimate limits when they are supposed to prove that these races might begin to be without any direct interposition of creative power. For, while the oak may spring from an acorn, and the largest animal from a microscopic monad, yet within the whole range of our experience both in the vegetable and animal kingdoms, _the seed is produced by the organism_, and necessarily presupposes it; whence it follows, either that there must have been an eternal succession of organisms producing seed, and thereby perpetuating the race, or if this be inconceivable, still more if it can be disproved by geological or historical evidence, then that the analogy of our present experience leads us up, not to "an infusorial point" or "microscopic monad," but to a primary living organism as the commencement of each existing tribe. In the words of Dr. Barclay, "It will not be easy, on any principles exclusive of the vital, to answer these questions, What was the origin of the first egg, or what was the origin of the first bird? For where is the egg that comes not from a bird, and where is the bird that comes not from an egg? To the mere materialists, who exclude every species of vitality but that from organism, this problem is nearly as embarrassing as the origin of the Universe itself."[38]

If these views be correct, all the natural analogies would lead us to acquiesce, as Dr. Barclay did, in the Mosaic narrative as the most philosophical account of the commencement of the present order of things. It traces up every race to a primary organism, endowed with reproductive powers; for it tells us, in regard to the FLORA, that God said, "Let the earth bring forth grass, _the herb yielding seed_, and the fruit-tree yielding fruit _after his kind_, whose _seed is in itself_, upon the earth; and it was so." And it tells us, with regard to the FAUNA, that God said, "Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven. And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, _after their kind_, and every winged fowl _after his kind_. And God blessed them, saying, _Be fruitful, and multiply_, and fill the waters in the seas, and let fowl multiply in the earth."

Here the distinction between different genera and species, and the provision that was made for the perpetuation of different races, are prominently presented; while the production, in the first instance, not of an "infusorial point" or "microscopic monad," but of a living organism capable of multiplying its kind, is expressly declared; and every race is traced up to that primary organism, in perfect consistency with the only law, whether of vegetable or animal reproduction, which is known to be in operation at the present day. And _this_ law of reproduction, so far from being exclusive of a primary act of Creation, seems to presuppose and require it; for there must be a living organism before there can be vital transmission. But the theory of Physiological Development proceeds on a totally different supposition,--a supposition for the truth of which we have not only no historical evidence, but not even the slightest _analogical presumption_, since we have no instance of development anywhere except from a germ or seed, produced by an organism preëxisting in a state of maturity.

But the exigencies of that theory demand a wide departure from all the familiar lessons of experience; and hence recourse has been had to a series of the wildest and most extravagant conjectures, such as may well justify the opinion of those who have held that the creed of certain philosophers makes a much larger demand on human credulity than that of almost any section of the Christian Church. For, according to that theory, the origin of the FLORA is first accounted for by the action of some element--probably electricity--on a certain _mucus_, which is supposed to be generated at those points where the ocean comes into contact with the earth and air; that is, on the shore of the sea at low water mark. MAILLET had broached the idea of the marine origin of all our present "herbs, plants, roots, and grains,"[39] at a period when the Universal Ocean, of which Leibnitz said so much, was still the creed of some speculative minds; but it has been more recently revived, and exhibited in greater detail, though not with stronger evidence, by some writers of our own age. Thus Dr. Oken tells us that "all life is from the sea;" that "when the sea organism, by self-elevation, succeeds in attaining into form, there issues forth from it a higher organism;" and that "the first organic forms, whether plants or animals, emerged from the shallow parts of the sea." And so the author of "The Vestiges" attempts to show that new races, both of plants and animals, marine and terrestrial, may be accounted for, without any act of immediate creation, by a change or transmutation of species resulting from the agency of natural causes. "There is," as he tells us, "another set of phenomena presented in the course of our history; the coming into existence, namely, of a long suite of living things, vegetable and animal, terminating in the families which we still see occupying the surface. The question arises,--In what manner has this set of phenomena originated? Can we touch at, and rest for a moment on, the possibility of plants and animals having likewise been produced in the way of Natural Law, thus assigning but one class of causes for everything revealed to our sensual observation? Or are we at once to reject this idea, and remain content either to suppose that creative power here acted in a different way, or to believe, unexaminingly, that the inquiry is one beyond our powers?"[40] In reply to these questions, he proceeds to show that "there is a balance of probability from actual evidence in favor of _an organic creation by law_," and that "in tracing the actual history of organic beings upon the earth," as revealed by Geology, we find that "these came not at once, as they might have been expected to do if produced by some special act, or even some special interposition of will, on the part of the Deity; they came in a long-continued succession, in the order, as we shall afterwards see more convincingly, of progressive organization, grade following grade, till, from an humble starting-point in both kingdoms, the highest forms were realized." Such is his general principle; and, without entering into the details, we may sum up his general argument by saying, in the words of another,[41] that, according to his theory, "dulse and hen-ware became, through a very wonderful metamorphosis, cabbage and spinach; that kelp-weed and tangle bourgeoned into oaks and willows; and that slack, rope-weed, and green-raw, shot up into mangel-wurzel, rye-grass, and clover." So much for the FLORA; and now for the _Fauna_, and the transition from the one to the other. His views are thus exhibited by Sir David Brewster: "The electric spark, escaping from the wild elements around it, struck life into an elementary and reproductive germ, and sea-plants, the food of animals, first decked the rude pavement of the ocean. The lichen and the moss reared their tiny fronds on the first rocks that emerged from the deep; land-plants, evolving the various forms of fruit and flower, next arose,--the Upas and the bread-fruit tree, the gnarled oak and the lofty cedar. Animal life appeared when the granary of nature was ready with its supplies. A globule, having a new globule forming within itself, which is the fundamental form of organic being, may be produced in albumen by electricity; and as such globules may be identical with living and reproductive cells, we have the earliest germ of organic life, the first cause of all the species of animated nature which people the earth, the ocean, and the air. Born of electricity and albumen, the simple monad is the first living atom; the microscopic animalcules, the snail, the worm, the reptile, the fish, the bird, and the quadruped, all spring from its invisible loins. The human similitude at last appears in the character of the monkey; the monkey rises into the baboon, the baboon is exalted to the ourang-outang, and the chimpanzee, with a more human toe and shorter arms, gives birth to man."[42]

The remarks which were offered, in the previous section, on Cosmical Development, are equally applicable, _mutatis mutandis_, to this other form of the doctrine of Creation by Natural Law. It might be shown, with reference to the supposed generation of plants and animals, just as it was then shown with reference to the generation of planets and astral systems, first, that the theory rests upon a mere hypothesis, which is utterly unsupported by experimental evidence; secondly, that the progress of science has hitherto afforded no ground to believe that the transmutation of species is provided for under the established constitution of nature; and, thirdly, that even were the theory admitted, it would not destroy the evidence of Theism, any more than the propagation of plants and animals under the existing system, which, so far from excluding or impairing, serves rather to enhance and illustrate the proof of creative wisdom and power. In support of this last position, we might adduce the testimony of the author of "The Vestiges" himself; for, referring to the idea that "to presume a creation of living beings by the intervention of law" is equivalent to "superseding the whole doctrine of the Divine authorship of organic nature," he takes occasion to say, "Were this true, it would form a most important objection to the Law theory; but I think it is not only not true, but the reverse of the truth. As formerly stated, the whole idea of law relates only to the mode in which the Deity is pleased to manifest His power in the natural world. It leaves the absolute fact of His authorship of and supremacy over Nature precisely where it was." He adds, in the words of Dr. Buckland, "Such an aboriginal constitution, so far from superseding an Intelligent Agent, would only exalt our conceptions of the consummate skill and power that could comprehend such an infinity of future uses under future systems, in the original groundwork of His Creation."[43]

But, without enlarging on those general considerations which were formerly stated, and which admit of an easy and obvious application to this _second_ form of the theory, we shall offer a few remarks bearing directly on its distinctive peculiarities, and directed to the exposure of its radical defects.

The theory rests on two very precarious foundations: the assumption of _spontaneous generation_, on the one hand, and the assumption of a _transmutation of species_ on the other. Each of these assumptions is necessarily involved in any attempt to account for the origin of the vegetable and animal races by natural law, without direct Divine interposition. For if, after the first organism was brought into being, the production of every subsequent type may be accounted for simply by a transmutation of species, yet the production of the original organism itself, or the first commencement of life in any form, must necessarily be ascribed either to a creative act or to spontaneous generation. A new product is supposed to have come into being, differing from any that ever existed before it, in the possession of vital and reproductive powers; and this product can only be ascribed, if Creation be denied, to the spontaneous action of some element, such as Electricity, on mucus or albumen. In this sense the doctrine of spontaneous generation seems to be necessarily involved in the first step of the process of Development, and is, indeed, indispensable, if any account is to be given of the origin of vegetable and animal life; but in the subsequent steps of the same process it is superseded by a supposed transmutation of species, whereby a lower form of life is said to rise into a higher, and an inferior passes into a more perfect organism.

But we have no experience either of spontaneous generation on the one hand, or of a transmutation of species on the other. Observation has not discovered, nor has history recorded, an authentic example of either. In regard to the _first_, the author of "The Vestiges" anticipates this objection, and attempts to answer it. The objection is, that "a transition from the inorganic to the organic, such as we must suppose to have taken place in the early geological ages, is no ordinary cognizable fact of the present time upon earth; structure, form, life, _are never seen_ to be imparted to the insensate elements; the production of the humblest plant or animalcule, otherwise than as a repetition of some parental form, is not one of the possibilities of science."[44] Such is the objection; and how does he attempt to answer it? He endeavors to show, first, that the work of creation having been _for the most part_ accomplished thousands of years ago, we have no reason to expect that the origination of life and species should be _conspicuously exemplified_ in the present day; secondly, that the comparative infrequency, or even the entire absence, of such phenomena _now_ would be no valid reason for believing that they have _never_ been exhibited heretofore, if, on other grounds, the doctrine of 'natural creation' or 'life-creating laws' can be rendered probable; and, thirdly, that even in our own times there ARE facts which seem to indicate the reality, or at least the possibility, of "the primitive imparting of life and form to inorganic elements."[45]

Now, to this elaborate argument in favor of _spontaneous generation,_ or the production of life by natural law, we answer, in the first place, that the mere fact of its being adduced in connection with the Theory of Development affords a conclusive proof that it is indispensable to the maintenance of that theory, that the hypothesis would be incomplete without it, and that no account can be given of creation by the mere doctrine of a _transmutation of species_. It is the more necessary to make this remark, because not a few who embrace the latter doctrine affect to disown the former, and seek to keep it out of view. But the one is as necessary as the other to a complete theory of Natural Development. The author of "The Vestiges" felt this, and virtually acknowledges it when he undertakes the task of vindicating the credibility of spontaneous generation. But we answer, in the second place, that the method in which he performs his self-imposed task is singularly curious, and not a little instructive. He had, it must be owned, a difficult game to play. The general theory of "The Vestiges" is founded on the fact that, in the ordinary course of Nature, the races of plants and animals are perpetuated by propagation, according to established Natural Laws,--a fact which might seem to afford a strong analogical argument in favor of the supposition that the same order of Nature is maintained also in the few apparently exceptional cases in which, from our defective knowledge, we are unable to trace the connection between the parent and the product. And yet the author evinces no little anxiety to make out a case in favor of "a non-generative origin of life even at the present day;" and he appeals to a class of facts, confessedly obscure, which have not been, as he thinks, satisfactorily accounted for by the law which usually regulates the production of organic beings. He refers us to the speculations of Dr. Allen Thomson on the primitive production of Infusoria,[46] to the facts which modern science, aided by the microscope, has discovered respecting the Entozoa, or the creatures which live within the bodies of others, and, above all, to the experiments of Mr. Crosse and Mr. Weekes, which seemed to result in the production of a small species of insect (_Acarus Crossii_) from the action of a voltaic battery on a saturated solution of the silicate of potash, or the nitrate of copper, or the ferrocyanate of potassium. The reason of his anxiety to avail himself of these cases is evident. The exigencies of his theory demanded a method of accounting for the primary origin of life different from any that can be found in the common process of propagation. He saw clearly enough that his main argument, founded, as it was, on the law of hereditary transmission, could not account for the production of the first organism; and that, if he would avoid either the doctrine of _Immediate Creation_, which is so offensive to him, or the idea of _Eternal Generation_, which is utterly excluded by the clearest lessons of Fossil Geology, he must have recourse to the hypothesis of _Spontaneous Generation_. Hence he attempts to account for the commencement of new species both of plants and animals, in the course of the world's history, by a transmutation of species; while, for the origin of the first species, he has recourse to the same law of Development, but acting in widely different circumstances, and giving rise to what he calls "aboriginal generation," whereby the inorganic passes into the organic, and life, form, and structure, are imparted to hitherto inert materials by the action of Electricity on mucus or albumen. To accomplish this twofold purpose, he felt it necessary to insist, in the first instance, on the ordinary law of generation as the established order of _mediate_ creation; while he found it equally necessary, in the second place, to insist on those apparently exceptional cases in which the connection between the germ and the product has hitherto eluded philosophical research,--and this for the purpose of showing that the original production of plants and animals was _not similar_ to the ordinary method of their propagation in any other respect than this, that in both cases the result is brought about by Natural Laws, without the direct interposition of any supernatural cause.

Now, in so far as his argument is founded on the principle of analogy,--and it is on this principle that it proceeds throughout,--we submit that it is radically vicious, and utterly inconclusive. For the vast majority of cases in which the commencement of life and organization falls under our notice being confessedly those, not of primary production, but of mediate reproduction, it is reasonable to believe that the same law governs all cases alike, whether we have been able or not to trace the origin of life to the principle of propagation, the few apparent exceptions being sufficiently accounted for by our imperfect knowledge of the causes and conditions on which they depend. Besides, the argument from analogy in favor of a primary production of life by natural causes, in so far as it is founded on the present law of hereditary transmission, is radically defective, since the two cases are widely different; the one presupposing _a primary organism of the same kind_, from which others are evolved by a law of natural succession, the other exhibiting life as a new product, resulting not from any prior organism, but from the action of _causes of a totally different kind_, which are not known to be capable of giving birth either to vegetable or animal organisms under the actual constitution of Nature.

But suppose, even, that the _Acarus Crossii_ were admitted to be a real product of Galvanic action on the silicate of potash, and an undeniable instance of "a non-generative origin of life," how would the illustrative example accord with the author's general theory? It might afford a specimen of aboriginal production; but how would it fit in with his favorite doctrine of _a gradual and progressive advancement_ from the lower to the higher forms of organization? The _Acarus_, at first supposed to be a new and hitherto unknown creature, is now acknowledged to be one of a very familiar species,--a species which may have deposited its ova, and propagated its kind, since the commencement of the present order of things, and whose eggs might very well resist the action even of nitrate of copper, since the creature itself could live in that poisonous mixture. Moreover, it belongs, in point of organization, to one of the highest orders of organisms; not to the _radiata_, not to the _mollusca_, but to the highest type of the _articulata_, the nearest to the _vertebrata_. Had it been a monad,--a mere living cell,--which Galvanism evolved from the solution, and had this primary product developed itself afterwards in various forms, according to the ascending scale of a progressively improving organization, it might have accorded admirably with the twofold doctrine of spontaneous generation and transmutation of species; but, unfortunately, the first process is so perfect, in the present instance, as to leave little room for the second, and we are almost tempted to hope that perhaps the clumsy and troublesome expedient of a transmutation of species may yet be superseded by the discovery of some method,--we know not what,--whereby not only the _articulata_, but the _vertebrata_, and even Man himself, may be immediately produced by some new combination of Nature's elemental laws![47]

We have given prominence, in the first instance, to the doctrine of "spontaneous" or "aboriginal" production, because it constitutes an indispensable part of the Theory of Development, and because we believe that, were this clearly understood, that theory would soon sink into general discredit or total oblivion, like the kindred speculations of Anaximander and Anaxagoras, of the old Ionic School. The experiments of Ehrenberg, instituted with the view of testing the doctrine of spontaneous generation, may be said to have decided the whole question. They did not succeed, indeed, in explaining every apparently exceptional case, for some of the facts are still obscure, and will probably continue to be so, notwithstanding every extension of microscopic power, just as, in the analogous case of the Nebulæ, the increase of telescopic power has enabled us to resolve not a few of them into clusters of stars, while it has served to bring others yet unresolved within the range of our vision. But they were sufficient, at least, to show that, as far as our clear knowledge extends, the one uniform law, "_Omne vivum ex ovo_," universally prevails, and that the whole analogy of Nature, in so far as its constitution has been ascertained, is adverse to the doctrine of spontaneous generation. Ehrenberg detected the minute germs of vegetable mould, and the ova of some of the smallest animalcules; and when it is considered that these germs and ova are so tenacious of vitality that certain prolific seeds have come down to us from the age of the Pharaohs in the wrappings of the Egyptian mummies,--that they are widely diffused in the air and the waters, insomuch that no sooner does a coral reef appear above the level of the sea than it is forthwith covered with herbage by means of seeds wafted by the winds or deposited by the waves,--and that it is almost impossible to exclude them by any artificial expedient, since they are capable of resisting the action of boiling water and even of alcohol itself,--it cannot, we think, be denied that the few cases which still remain obscure or unexplained may be, at least, _probably_ accounted for in accordance with the same natural law which is found to be invariably established in every department to which our clear knowledge extends.

In regard, again, to the supposed "transmutation of species," we are equally warranted in affirming that it is destitute of all experimental evidence, and unsupported even by any natural analogy. As the doctrine of spontaneous generation stands opposed to the maxim that _organic life can be produced only by organic life_, so the doctrine of a transmutation of species stands opposed to the equally certain maxim that _like produces like, both in the vegetable and animal kingdoms_. Cuvier has demonstrated, with reference to the birds and reptiles preserved in Egypt, an entire fixity and uniformity of species, in every, even the least, particular, for at least three thousand years.[48] In the actual course of Nature we see no tendency to change; nay, a barrier seems to have been erected in the constitution of Nature itself to prevent the possible confusion of races by promiscuous intercourse, through that provision which renders the mule incapable of reproduction. No plant has ever been found in a state of transition from a lower to a higher form; no instance has ever been produced of one of the algæ being transmuted into the lowest form of terrestrial vegetation; nor of a small gelatinous body developing itself into a fish, a bird, or a beast; nor of an ourang-outang rising into a man.[49] It is true, indeed, that "there is a capacity in all species to accommodate themselves, to a certain extent, to a change of external circumstances, this extent varying greatly according to the species. There may thus arise changes of appearance or structure, and some of these changes are transmissible to the offspring; but the mutations thus superinduced are _governed by constant laws and confined within certain limits_. Indefinite divergence from the original type is not possible, and the extreme limit of possible variation may usually be reached in a short period of time; in short, species have a real existence in Nature, and a transformation from one to another does not exist."[50]

The whole science of Natural History is based on the existence of distinct species, capable of being discriminated from each other by certain characteristic marks; and the whole art of the agriculturist and the stockbreeder proceeds on the assumption of a law, invariable in its operation, whereby "like produces like in the vegetable and animal worlds." The instances to which the author of "The Vestiges" refers in support of his theory are utterly frivolous when opposed to the copious inductions to which they are opposed; and they may all be explained consistently with the _law of variation within definite limits_, as stated by Dr. Whewell, or by our ignorance of all the conditions involved in each particular case. Nor is his argument founded on the limited range of our observation, even with its singular illustration derived from Mr. Babbage's calculating engine, fitted to diminish, in the slightest degree, our confidence in the general results of these inductions; for, not to mention that it amounts to nothing more than an appeal from what we do know to what we do not know, from knowledge to ignorance, from the certainties of science to the mere possibilities of conjecture, it has been well shown by Mr. Miller, that our range of observation is not so limited as the author of "The Vestiges" would have us to believe, since "_extent of space_ is, in a matter of this kind, equivalent to _duration of time_. For, although no man has lived five hundred years, so as to observe the gradual development of the oak from the acorn in its various stages of progress, yet every man who can survey five hundred yards of an English forest, can see the oak in every stage of its growth, and need have no doubt as to the law of its progressive development. And so, had there really been such a transmutation of species as is contended for, we might expect to find, somewhere on the vastly extended sea coasts of our islands and continents, some specimens of plants or animals in a state of transition from the lower to the higher forms."

We are told, indeed, in answer to this argument, that Mr. Babbage's engine produces numbers according to a certain law up to a particular point, and then, most unexpectedly, perhaps even unaccountably, the law of the series is changed, and the next term exhibits a striking departure from the order previously followed; and so, it is argued, it may be in nature. Each organism may propagate after its kind for immense periods, so as to give the impression of this being an invariable law; but at a certain stage the order may change, and the next term in the series may differ from all that went before it. The argument--if it can be called an argument--amounts to this: Mr. Babbage's machine produces a _series of numbers, and of numbers only_, but according to different laws of succession; _ergo_, Nature may produce in the same way, and with similar variations, _different races of plants and animals_. The argument would have been perfect if the engine had produced _something else than numbers_; if, as Professor Dod supposes, "while watching Mr. Babbage's machine, presenting to us successive numbers by the revolution of its plates, we should suddenly see one of those plates resolving itself into types, and these types arranging themselves in the order of a page of 'Paradise Lost,' or even of 'The Vestiges of Creation;'--in such a case, there might have been something in the argument; but even then, the withering question remains, Is there any man in his senses who would not immediately conclude that _some new cause was now at work_?"

In short, in so far as the _facts of the case_ are concerned, there is not only no known instance either of "spontaneous generation" or of "transmutation of species," but there is not even any natural analogy that can give the theory the slightest aspect of verisimilitude. The author of "The Vestiges" thinks that a presumption in its favor may be derived from "the analogy of the inorganic world,"--in other words, from the supposed conversion of nebulæ into planets and astral systems by the operation of natural causes; but this analogy has been conclusively set aside by disproving the hypothesis on which it depends. He further thinks that a favorable presumption may be derived from "the analogy of the organic world,"--in other words, from the process of propagation by which the races of plants and animals are perpetuated; but the presumption thence derived, so far from being favorable, is directly opposed to his theory, since all the facts which come under our cognizance in every department of Nature serve only to establish the two great maxims of Natural History,--that _organic life can spring only from organic life_, and that _like produces like, both in the vegetable and animal world_.

If we have succeeded in disposing of _the facts of the case_, we shall have little difficulty in exposing _the fallacy of the principles_ which are involved in the author's speculations on this subject. It is of fundamental importance, in this inquiry, to form a clear and correct conception of the precise point at issue, and of the two alternatives between which we are called to make our choice. It has been well said that "the great antagonist points in the array of the opposite lines are simply the LAW of Development _versus_ the MIRACLE of Creation."[51] And the author of "The Vestiges" virtually acknowledges this to be the real state of the question, when he says that "if we can see no _natural_ origin for species, a _miraculous_ one must be admitted."[52] Now, the grand alternative being Creation by Miracle or Creation by Law, that is, Creation by a Natural or by a Supernatural cause, we affirm that it is utterly presumptuous and unphilosophical to represent the one as less worthy of God, or more derogatory to His infinite perfections, than the other. Yet the author does not hesitate to say that the _natural_ ought to be preferred to the _miraculous_ method of accounting for the origin both of planets and of their inhabitants, for this among other reasons, that the latter would be derogatory to the wisdom and power of the Most High. His words are remarkable: "The Eternal Sovereign arranges a solar or an astral system by dispositions imparted primordially to matter; He causes, by the same majestic means, vast oceans to form and continents to rise, and all the grand meteoric agencies to proceed in ceaseless alternation, so as to fit the earth for a residence of organic beings. But when, in the course of these operations, fuci and corals are to be for the first time placed in those oceans, a particular interference of the Divine power is required; and this special attention is needed whenever a new family of organisms is to be introduced,--a new fiat for fishes, another for reptiles, a third for birds; nay, taking up the present views of Geologists as to species, such an event as the commencement of a certain cephalopod, one with a few new nodulosites and corrugations upon its shell, would, on this theory, require the particular care of that same Almighty who willed at once the whole means by which infinity was replenished with its worlds?" ... "Is it conceivable, as a fitting mode of exercise for Creative Intelligence, that it should be constantly paying a special attention to the creation of species, as they may be required in each situation throughout those worlds at particular times? Is such an idea accordant with our general conception of the dignity, not to speak of the power, of the Great Author?" ... "It would be distressing to be compelled to picture the power of God as put forth _in any other manner_ than in those slow, mysterious, universal laws which have so plainly an eternity to work in."[53]

Such is the author's presumptuous decision on a matter which is far "too high for him." We offer the following remarks upon it:

_First_ of all, let it be observed that, unless on the principle of absolute Atheism, which he professes to repudiate, he cannot but acknowledge that _once_, at least, the power of God must have been put forth _in another manner_ than "in those slow, mysterious, universal laws" of which he speaks; and that, even if he could succeed in disproving "repeated interferences of creative power," he could in nowise dispense with a primitive act of direct, immediate, supernatural creation, since he does not profess to believe in the eternal existence of matter and its laws. We find, indeed, that even in the subsequent acts of a continuous, but mediate creation, he is compelled to acknowledge a supernatural power as acting, in each individual case, according to established natural laws; for he says expressly, "There cannot be _an inherent intelligence in these laws_; the intelligence appears _external to the laws_, something of which the laws are but as the expression of the will and power. If this be admitted, the laws cannot be regarded as primary or independent causes of the phenomena of the physical world. We come, in short, to a being beyond Nature,--its Author, its God." ... "When we speak of Natural Law, we only speak of _the mode in which the Divine power is exercised_; it is but another phrase for _the action of the ever-present and sustaining God_."[54] It is admitted, then, _first_, that there must have been a primary act of creation, in the highest and strictest sense, by a direct and immediate interposition of Divine power, at the commencement of created existence; and, _secondly_, that, even in the continuous work of creation, which is supposed to have been subsequently carried on after the method of development by established natural laws, Divine agency is still equally real, although it is differently manifested, and is indispensably necessary to account for the resulting products. Now, can it be reasonably asserted that the direct and immediate creation of such a being as Man would be more derogatory to the wisdom and power of God than the primordial production of "a universal Fire-Mist," or even of "electricity and albumen?" or, will it be pretended that immediate creation of molluscs as molluscs, of fishes as fishes, of reptiles as reptiles, would be less worthy of the great Author of Nature than the establishment of a system which _must_ in due time give them birth, and that, too, not without the concurrence and coöperation of the Divine will; for "natural law is but another phrase for _the action_ of the ever-present and sustaining God?"

But, while we hold that there is no good ground for an affirmative answer to these questions, we would carefully guard against rushing to the opposite extreme, and affirming, either that the production of new races by the method of natural law was, on _a priori_ grounds, impossible, or that God might not have adopted that method, had He so pleased, in perfect consistency with the manifestation of His wisdom and power. We see that He has done so, under the actual constitution of Nature, so far as the production of _individuals_ is concerned; we see not why a similar provision might not have been made for the production of _genera and species_. In either way His power and His wisdom might have been displayed. But, when we are told that the one is derogatory to the Divine Majesty, and the other alone consistent with the loftiest views of His perfections, we denounce the whole speculation as one that is alike presumptuous and unphilosophical, on the simple but conclusive ground that we are in no degree competent judges of the best method either of creating or of governing the world. Had we been asked to say whether it was likely that, under the rule of infinite wisdom and almighty power, certain insects, reptiles, and fishes, that are unattractive to the eye, and loathsome to the fastidious taste of many, could find a place at all among the works of God, we might have thought it improbable that they should be created; but they exist notwithstanding, and the fact of their existence is enough to silence all our presumptive reasonings. And surely it is not less--it is much more--presumptuous to affirm that, existing as they do, they could not have been brought into being, without disparagement to Divine wisdom, otherwise than by the action of established laws, or by a process of natural development; as if it were unworthy of God to _produce_ that for whose production He confessedly did make _provision_.

But, further, we see here very strikingly exemplified the tendency of such speculations to _exclude God from all real, active, and direct connection with His works_. The dominion of Natural Law, which, as we shall afterwards see, is held by M. Comte and Mr. Combe to exclude the doctrine of a special Providence and the efficacy of prayer, is here extended, by the author of "The Vestiges," so as to be exclusive also of any direct Divine interposition in the work of Creation itself, other than what may have been implied in the aboriginal production of matter and its laws, or in the subsequent concurrence of His will with the action of these laws in the established order of Nature.

We have said that the Theory of Development, as expounded in "The Vestiges," is not necessarily atheistic, partly because the author professedly disclaims Atheism, and partly also because, in strict logic, it might still be possible, even on the basis of that theory, considered simply in itself and apart from the speculations with which it has been associated, to construct, from the actual phenomena of Nature, a valid proof for the being and attributes of God. And yet we have thought it necessary to advert to it as one of the recent speculations of science, because, whatever may be its _professed aim_, its _practical tendency_ is unquestionably hostile to the influence of religious truth. It will be found, in the great majority of cases, and especially in the case of ardent youthful minds, that this theory, when it is embraced as an article of their philosophic creed, is, to all practical purposes, tantamount to Atheism. For not to insist on the consideration, so forcibly stated by others,[55] that the natural argument for the Immortality of Man, or for the doctrine of a Future Life, as implying distinct individuality and continued self-consciousness, must be materially weakened, if not entirely neutralized, by a theory of development which traces the human lineage up through the monkeys and fishes to albumen impregnated by electricity, or, further still, to a diffused Nebula or universal Fire-Mist,--we think that the Sensational and Materialistic speculations with which the work abounds have a tendency to weaken the evidence for a living, personal, spiritual God, as the Creator and Moral Governor of the world, and to diminish that reverence, confidence, and love, which these aspects of His character alone can inspire. The system of Epicurus, although it contained a formal recognition of a First Cause, has always been held to be practically atheistic, simply because it removed God from the active superintendence of the affairs of the world, and excluded the doctrine of a special providence and of a moral government. It was held, in the words of Cicero, "Epicurum verbis reliquisse Deos,--re sustulisse."[56] And so, in "The Vestiges," Natural Law is substituted for Supernatural Interposition, not only in the common course of Providence, but in the stupendous work of Creation itself.
