This reasoning is not destitute of plausibility. For there is scarcely any lesson more forcibly impressed on short-lived man than the mutability of the world. And it is indeed true that change is its most striking attribute. But when we look at the subject philosophically, we find that all this mutability is consistent with the most perfect ultimate stability; nay, that the change is essential to secure the stability. Apart from what revelation and geology teach, these changes in nature form cycles, which, like those in astronomy, are perfectly consistent with the eternal permanence of the general system to which they belong. In the motions of the heavenly bodies, a considerable amount of irregularity and oscillation about a mean state does not tend to the ruin, but rather to the preservation, of the system, provided the anomalies do not extend beyond certain limits. It is just so with other changes that are going on around us. All of them are, in fact, as much regulated by mathematical laws as the perturbations of the heavenly bodies; although those laws are more complicated and difficult to bring out in distinct formulae in the former case than in the latter. Yet even in astronomy, it is not many years since the mutual disturbances among the heavenly bodies were supposed to be the certain precursors of ruin to the system. It was not till the famous problem of the three bodies was solved, by the use of the most refined mathematical analysis, that astronomers learnt the true operation of those causes of disturbance among the heavenly bodies which exist in their mutual attractions. It was then found that, so balanced are they in their action, and so narrow their limits, that they can never affect the stability of the system; or, rather, they secure that stability. It is, indeed, true, that when changes in nature go on increasing or decreasing in magnitude indefinitely, they clearly indicate a beginning and an end to the system to which they belong. And it was on this principle that the earlier astronomers predicted that the celestial perturbations would ultimately bring the universe to a state of chaos. They found, for instance, that the moon's orbit was decreasing in size, and they inferred that, ultimately, that luminary must come to the earth. But they now know it to be mathematically certain that, after a long period, the diminution of the orbit will cease; it will begin to expand, and go on expanding,-until the opposite point of oscillation is reached, when it will again diminish; and in this manner, if God's will permit, perform its eternal round. Just so it is with all the irregularities of the solar system.

"Yonder starry sphere Of planets, and of fixed, in all her wheels, Resembles nearest mazes intricate, Eccentric, intervolved, yet regular; Then most, when most irregular they seem."

And so it is with all the natural changes which we witness around us, and with all which science shows us to have taken place on the globe, excepting some which geology discloses, and perhaps one which astronomy renders probable. Let us look at some of those changes which the argument under consideration regards as inconsistent with the world's eternity.

Nearly all the changes in nature with which we are acquainted belong to three classes,--the mechanical, the chemical, and the organic. Astronomical changes are purely mechanical; and hence the ease with which they may be calculated by mathematics. The universal system of death, which reigns over all animals and plants, is the result of organic laws; and it is this which probably gives to man the strongest impression of the transient nature of sublunary things. But just consider the antagonist agencies to this universal destroyer. I refer to the equally universal system of reproduction, and to the law by which permanence of species is secured. The consequence is, that, while every individual animal and plant dies, the species survives. In the whole history of the animals and plants now existing on the globe, only eight or ten certain examples are on record in which a species has become extinct, and those are some large birds, such as the dinornis and dodo, once inhabitants of the Isle of Bourbon and New Zealand. Every one of the human family, every elephant, every ox, every lion, &c., die, but man, as a species, still lives; and so does the elephant, the ox, and the lion; and most obviously this is a law of nature. How easy, then, for the atheist to evade the force of your argument against the world's eternity, drawn from the ravages of death! He has only to suppose the havoc of individuals by death always to have been repaired by the equivalent operation of reproduction, and that these two agencies have been balanced against each other from eternity; and how will you prove this impossible, except by the absurd metaphysical arguments already considered?

Atmospheric and aqueous changes often, and, indeed, generally, appear more chaotic and destitute of a controlling force than any others in nature. When the winds are let loose from their prison-house; when the heavens become dark, and the clouds, rent by the lightnings, pour down their contents, and the swollen torrents carry desolation down the mountain's side and over the wide plain; when the ocean rolls in upon the land its giant waves; when the tornado sweeps all before it, in rich tropical regions; or when the sirocco sends its hot blast, loaded with sand, over the devoted surface,--in all these cases, how difficult for us to conceive that all this uproar among the elements is limited and controlled by laws as fixed and unalterable as those which regulate the heavenly bodies! Nevertheless, it must be so; and although the winds and the waters seem to be rioting at their pleasure, there are, in fact, at work antagonist agencies; which will confine their wild war to a narrow field, and soon bring them again into peaceful submission. For such has always been the case, and the limits of their irregularities are no wider now than six thousand years ago. In other words, the repressing agency has always been superior to the destroying force, when the latter has risen to a certain limit; and I doubt not but the profounder mathematics of angelic minds might as easily calculate the anomalies and perturbations of winds and waves as the formulas of La Place can determine those of the solar system. And if such constancy has existed for six thousand years in meteorological changes,--of all others in nature apparently the most irregular,--why, the atheist will ask, may not that constancy have been eternal? And with equal reason may he ask the same in respect to all changes resulting from mechanical, chemical, and organic laws, which we witness in nature, except those which come within the province of geology, and even concerning some of those; and what changes in the material world do not result, directly or remotely, from one or two, or all of these laws? Yet, in regard to all these changes, there is no inconsistency in supposing them to have gone on in an eternal series; and hence they furnish no proof of the non-eternity of the world.

In the seventh and last place, the recent origin of society, as shown by historical monuments, is regarded as evidence of the recent origin of the world. This argument was well understood as long ago as the days of Lucretius, who states it very clearly in the oft-quoted lines,--

"Si nulla fuit genitalis origo, Terrarum et coeli, semperque eterna fuit, Cur, supra bellum Thebanum et funera Trojae, Non alias alii quoque res cecinere poetae?"

This argument, though it has been met by a plausible reply, is certainly of great importance in its bearing upon the recent origin of the human race, which, as we shall shortly see, is a point of much interest. But it is obvious that it proves nothing respecting the origin of matter, since this might have had an eternal existence before man was placed upon it. We need not, therefore, be delayed by its discussion.

Such is a fair summary, as I believe, of the arguments usually adduced, aside from the Bible and geology, to prove the non-eternity of the world. I am not prepared to say that they amount to nothing; but I do believe that they perplex, rather than convince, and that some of them are mere metaphysical quibbles.

They do not produce that instantaneous conviction which most of the arguments of natural theology force upon the mind; and it is easy to see how a man of a sceptical turn should rise from their examination entirely unaffected, or affected unfavorably. Let us now, therefore, turn to geology, and inquire whether its archives will afford us any clearer light upon the subject.

And here we must confess, at the outset, that geology furnishes us no more evidence than the other sciences of the creation of the matter of the universe out of nothing. But it does furnish us with examples of such modifications of matter as could be effected only by a Deity. Suppose, then, we should be obliged to acknowledge to the atheist, that we yield to him the point of matter's eternal existence, if he pleases, because we can find nowhere in nature decisive evidence of its creation, and then take our stand upon the arrangements and metamorphoses of matter. Or, rather, suppose we say to him, that we shall not contend with him as to the origin of matter, but challenge him to explain, if he can, without a Deity, its modifications, as taught by geology. If that science does disclose to us such changes on the globe as no power and wisdom but those of an infinite God could produce, then of what consequence is it, so far as religion is concerned, whether we can, or cannot, demonstrate the first creation of matter? I can conceive of no religious truth that would be unfavorably affected, though we should admit that this point cannot be settled. Let us, then, at least for the sake of argument, admit that it cannot be, and proceed to inquire whether, aside from this point, geology does not teach us all that is necessary to establish the most perfect system of Theism. I shall select four examples from that science, each of which is independent of the others in its bearing upon the subject, since in this way the argument will become cumulative; and if some are not satisfied with one example, the others may produce conviction.

In the first place, geology teaches that the time has been when the earth existed as a molten mass of matter, and, therefore, all the animals and plants now existing upon its surface, and all those buried in its rocky strata, must have had a beginning, or have been created. I should be sustained by many probabilities, were I to go farther, and maintain that the time was when the globe existed in a gaseous state--an opinion very widely adopted by able philosophers of the present day. But as this view is more hypothetical than my first position, which makes the earth a liquid mass, and as nothing would be gained to the argument by supposing it in a gaseous state, I shall not press that point. That it was once in a state of fusion is probable from the very great heat still remaining in its interior. But more direct proof of this results from the facts, now admitted by almost all geologists, that the unstratified rocks have all been melted, and that the stratified class have all, or nearly all, been the result of disintegration and abrasion of the unstratified masses. A striking confirmation of this opinion is the spheroidal figure of the earth,--a figure precisely such as the globe would have assumed in consequence of rotation, had it been in a fluid state. In fine, so many and so decisive are the facts which point to the original igneous fluidity of the globe, that no competent judge thinks of doubting that all the matter of which it is composed, certainly its crust, has some time or other been in that state. It is, however, the opinion of some geologists of distinction, that the whole of it was not in fusion at the same time, and that its different portions have passed successively through the furnace. But this view of the subject scarcely affects my argument, since at whatever period the fusion of any part took place, the destruction of organic life, if it existed, must have been the consequence. The essential thing is, to show that such was once the state of the earth that animals and plants could not have existed on it. For if such was the case, their creation must have been a subsequent operation; and if this did not require an infinite Being to accomplish it, no result in nature would demand his agency.

To prove the original igneous fluidity of the globe, we might have adopted another course of argument. All will admit that the present temperature of the interior of the earth is far more elevated than that of the surrounding planetary spaces. The inevitable result is, from the known laws of heat, that its radiation into the celestial spaces is constantly going on, and consequently the earth's temperature is being constantly lowered. Who can tell us now when this process of refrigeration commenced? If no one, then there must have been a time when the heat was great enough to fuse the whole globe. And the facts already stated confirm such an inference. For all the efforts hitherto made to show that the earth may be passing through regions of various temperatures, in its march around the centre of centres, amount to nothing more than dreamy conjecture.

In order to feel the force of the argument, sustained by so many facts in geology, just picture to yourselves this vast globe as a mass of liquid fire. From such a world every thing organic must have been excluded, and every thing combustible consumed, and only such combinations of matter have existed as incandescent heat could not decompose. Compare such a world with that now teeming with life, and beauty, and glory, which we inhabit; and say, must not the transition to its present condition have demanded the exercise of infinite power, infinite wisdom, and infinite benevolence? You can, indeed, conceive how a solid crust might have formed over the vast fiery ocean, by the simple radiation of heat; and then, too, by natural laws, might the vapors have been condensed into oceans and clouds, while volcanic force within might have lifted up our continents and mountains above the flood. But what a picture of desolation and ruin would such a world present, while unadorned with vegetation, and with no voice of life to break the stillness of universal death! Here is, then, the precise point where we need the interference of a Deity. Admit, if you please, that atheism, with its eternal matter and the laws of nature at command, might form a world without inhabitants. Who does not see, that to bestow organization, and life, and instinct, to say nothing of intellect, upon brute matter, is the loftiest prerogative of Jehovah? especially to fill so vast a world as ours with its teeming millions, exhibiting ten thousand diversities of size, form, and structure.

Let the atheist then exult in the belief of an eternal world. Geology shows him that it must have been without inhabitants; and that, therefore, the most wonderful part of the creation still remains to be accounted for; while physiology teaches that the interference of an infinite Deity can alone solve the enigma.

My second example from geology to disprove the notion of an eternal series of animals and plants on the globe, is derived from the history of organic remains. That history shows us clearly, that the earth, since its creation, has been the seat of several distinct economies of life, each occupying long periods, and successively passing away. During each of these periods, distinct groups of animals and plants have occupied the earth, the air, and the waters. Each successive group has been entirely distinct from that which preceded it, though each group was exactly adapted to the existing state of the climate and the food provided; so that, had the different groups changed places with one another, they must have perished, because their constitutions were adapted only to the state of things during the period in which they actually lived. A distinguished naturalist has recently declared that "he has discovered, in surveying the entire series of fossil animal remains, five great groups, so completely independent that no species whatever is found in more than one of them."--_Deshayes._

Including the existing races, this would give us six entirely distinct groups of organic beings that have lived in succession upon this globe since it became a habitable world. But even if it should be found that a few species are common to adjoining groups, the great truth would still remain, that the different groups were too much unlike to be contemporaries, and that consequently a new creation must have taken place whenever each new group commenced its course.

It is probable the earth has changed its inhabitants more than the six times that have been mentioned; some think as many as twelve times. But a larger number cannot yet be proved so clearly; and could they be, they would add nothing to this argument; for it rests mainly on the fact that this change of organic life has even once been complete. We may, however, very safely assume that the present animals and plants are the sixth group that have occupied the globe.[12]

These facts being admitted, and who does not see the necessity of divine interference, whenever one race of animals and plants passed from the earth in order to repeople it? It is not difficult to conceive how volcanic fires, or aqueous inundations, may have carried universal destruction over the globe, and bereft it of inhabitants. But where, save in the fiat of an infinite Deity, is the power that can make this universe of death teem again with life and beauty? In the powerful language of Dr. Chalmers, we may inquire, "Is there aught in the rude and boisterous play of a great physical catastrophe that can germinate those exquisite structures, which, during our yet undisturbed economy, have been transmitted in pacific succession to the present day? What is there in the rush, and turbulence, and mighty clamor of such great elements, of ocean heaved from its old resting-place, and lifting its billows above the Alps and the Andes of a former continent,--what is there in this to charm into being the embryo of an infant family, wherewith to stock and to repeople a now desolate world? We see in the sweeping energy and uproar of this elemental war enough to account for the disappearance of all the old generations, but nothing that might cradle any new generations into existence, so as to have effloresced on ocean's deserted bed the life and loveliness which are now before our eyes. At no juncture, we apprehend, in the history of the world, is the interposition of the Deity more manifest than at this; nor can we better account for so goodly a creation emerging again into new forms of animation and beauty from the wreck of the old one, than that the spirit of God moved on the face of chaos, and that nature, turned by the last catastrophe into a wilderness, was again repeopled at the utterance of his word."

Sir Isaac Newton has said, that "the growth of new systems out of old ones, without the mediation of a divine power, seems to me apparently absurd." He seems in this passage to have referred only to the arrangements of matter, "with respect to size, figure, proportions, and properties," and not to the principle of life, of instinct, or of intellect. But when the latter are taken into the account, it must be superlatively absurd to suppose new systems can grow out of old ones by merely natural operations. He, indeed, who can bring himself to believe, with a certain writer, that "the instincts of animals are nothing more than inert and passive attractions, derived from the power of sensation, and the instinctive operations of animals nothing more than crystallizations produced through the agency of that power,"--such a man could probably easily persuade himself that, by the help of galvanism, animals and plants might be the result of natural operations. Such doctrines, however, we shall examine in another lecture.

My third example from geology, showing the non-eternity of the present condition of the globe, is the fact of the disappearance of several large species of animals since the commencement of the most recent or alluvial geological period. Certain large pachydermatous and other animals, such as the fossil elephant, the mastodon, the megatherium, the mylodon, the megalonyx, the glyptodon, the fossil horse, ox, deer, &c., also nine or ten species of huge birds--the dinornis, the palapteryx, aptornis, notornis, and nestor of New Zealand, the dodo of Mauritius and Bourbon, and the pezohaps or solitaire of Rodriguez,--have ceased to exist since the tertiary period; some of them--the birds, for instance--since man's creation. Now, if any important species of animals from time to time disappear from any system of organic life, it shows a tendency to ruin in that system; for such is the intimate dependence of different beings upon one another, that you cannot blot out one, certainly not a large number, without disturbing the healthy balance between the whole, and probably bringing the whole to ultimate ruin. At any rate, if several species die out by natural processes, no reason can be given why others should not, in like manner, disappear. And to prove that any organic system shows a tendency to ruin is to show that it had a beginning.

My third example from geology, demonstrating the special interference of the Deity in the affairs of this world, is the fact of the comparatively recent commencement of the human race. That man was among the very last of the animals created is made certain by the fact that his remains are found only in the highest part of alluvium. This is rarely more than one hundred feet in thickness, while the other fossiliferous strata, lying beneath the alluvium, are six miles thick.

Hence man was not in existence during all the period in which these six miles of strata were in a course of deposition, and he has existed only during the comparatively short period in which the one hundred feet of alluvium have been formed; nay, during only a small part of the alluvial period. His bones, having the same chemical composition as the bones of other animals, are no more liable to decay; and, therefore, had he lived and died in any of the periods preceding the alluvial, his bones must have been mixed with those of other animals belonging to those periods. But they are not thus found in a single well-authenticated instance, and, therefore, his existence has been limited to the alluvial period. Hence he must have been created and placed upon the globe--such is the testimony of geology--during the latter part of the alluvial period.

I might include in this example nearly all the other species of existing animals and plants, since it is only a very few of these that are found fossil, and such species are limited to the tertiary strata. But since this might make some confusion in the argument, and since man is confessedly at the head of the existing creation, I prefer to let his case stand out alone, and to regard it _instar omnium_.
