Fables of Infidelity and Facts of Faith / Being an Examination of the Evidences of Infidelity

1. Analogy is a very unsafe guide here, because the differences between the limited life of the individual, and the alleged unlimited life of the race, are precisely those of which we have no analogy.

2. It is not true that "the original substratum or material is in every instance alike," nor that the "primordial cell is in every instance the same," whether of the "lichen or the man;"[21] nor as others allege, "that chemical reagents detect no differences between them." Chemical reagents are very clumsy instruments for the analysis of living beings, and their properties and powers; which are the antagonists of chemical reactions. Nevertheless, heat is a well-known chemical agent, and the application of heat to a fertilized, and to an unfertilized, germ develops a whole world of difference between them. The one becomes a chicken, the other an addled egg. Moreover, the application of different degrees of heat to different germs produces the most various reactions. The germs of trout are speedily killed by the moderate temperature of 65° Fahrenheit, while the germs of most animalculæ and plants develop rapidly at that temperature. Such instances might be multiplied, but these are sufficient to contradict the rash assertion of sameness, because a hasty observer did not take pains to discover differences.

3. There are four distinct plans of structure in the animal kingdom, and at least three, perhaps more, in the vegetable kingdom; and every germ, from the first instant when its evolution can be seen at all, is seen to develop only according to its own proper method. There is no more confusion of germs, or embryos, than of plants or animals.

4. No instance has ever been known of a germ producing an animal, or plant, of another species, by any process of stopping short of ripening, or undue prolongation of it. Every seed breeds true to its kind, or not at all, or produces a deformity. Embryology utterly refuses the notion of the transmutation of species.

Mr. Darwin's various references to rudimentary organs, like the bones of a hand in the flipper of the whale, or the teats of male animals, and the like, can hardly be called arguments. He tries to account for them and fails; acknowledging ignorance of the laws of heredity. Some of them he will have to be young organs in process of evolution, others organs aborted for want of exercise. In this category he ought to place the tail which he ought to have inherited from his ancestors, as he is greatly exercised to know what became of it. But it is evident that his attempts to build arguments on such things, and to account for occasional variations by atarism, are in contradiction to his principles. Most of the known instances of the origination of permanent varieties were not the result of infinitesimal improvements, but were sudden and complete at once. The Japan peacocks, the short-legged sheep, the porcupine man and his family, and the six-fingered men, were not at all the results of a slow process of evolution; on the contrary, they were born so, complete at once, in utter contradiction of the theory.

5. The only other line of argument, which has any show of probability, is that based upon the gradations of the various orders of plants and animals. Not but that there are many other arguments adduced, but they are of too technical a character to be intelligible to any but zoologists, and of too little weight to demand consideration after the leading arguments are overturned. But this argument from gradation, though logically unsound, is plausibly specious, and therefore demands notice.

By far the ablest exhibition of this argument is that made by Lamarck, and we give it as he presents it: "The greater the abundance of natural objects assembled together, the more do we discover proofs that everything passes by insensible shades into something else; that even the more remarkable differences are evanescent, and that nature has for the most part left us nothing at our disposal for establishing distinctions, save trifling, and in some respects puerile particularities. We find that many genera among plants and animals are of such an extent, in consequence of the number of species referred to them, that the study and determination of these last have become almost impracticable. When the species are arranged in a series, and placed near to each other, with a due regard to their natural affinities, they each differ in so minute a degree from those next adjoining, that they almost melt into each other, and are in a manner confounded together. If we see isolated species, we may presume the absence of some more closely connected, and which have not yet been discovered. Already there are genera, and even entire orders, nay, whole classes which present this state of things." He then goes on to present, "as a guide to conjecture," what his successors now assert as a fact: "In the first place, if we examine the whole series of known animals, from one extremity to the other, when they are arranged in the order of their natural relations, we find that we may pass progressively, or at least with very few interruptions, from beings of more simple to those of more compound structure; and in proportion as the complexity of their organization increases, the number and dignity of their faculties increase also. Among plants a similar approximation to a graduated scale of being is apparent. Secondly, it appears, from geological observations, that plants and animals of more simple organization existed on the globe before the appearance of those of more compound structure, and the latter were successively formed at more modern periods, each new race being more fully developed than the most perfect of the preceding one."[22]

From this gradation of nature, thus stated, the evolutionists go on to infer genealogy, the birth descent of the larger from the smaller, and of the more complex from the simpler forms, as the only scientific explanation. But it is by no means the only scientific explanation of the order of nature. The best naturalists, from Moses to Agassiz, have regarded the order of nature as the development of the divine idea, have prosecuted their researches on that view, and have regarded that as a sufficient and scientific explanation of the gradation of plants and animals, as they actually exist.

The idea of birth descent can not be logically connected with that of gradation; especially with a gradation upward. Were the order of nature such as Lamarck describes, how could any man logically infer the birth descent of each of its classes from the next below? Here is an ironmonger's sample card of wood screws, beginning with those one-quarter of an inch long, and proceeding by gradations of one-sixteenth of an inch to those of four inches. Does the gradation show that the little ones begot the big ones? It may be said the wood screws do not beget progeny. Well, here is a hill containing twenty-three potatoes, weighing from half an ounce to half a pound, and quite regularly graded. Did the small potatoes beget the big ones? The inference of birth descent from gradation is utterly illogical, and of a piece with the incoherency which we have seen in the other parts of the theory. It never could be inferred from the facts stated, even did nature correspond to Lamarck's description.

But nature does not correspond to Lamarck's description. That description corresponded moderately, perhaps, to the science of his day, which was based chiefly upon external resemblances; but no scientific naturalist of the present day would accept it as a correct statement of the facts revealed by modern science.
