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
