Finally, the professor says that he spoke of the Miltonic theory rather than of the “Mosaic doctrine,” because “we are now assured upon the authority of the highest critics, and even of dignitaries of the church, that there is no evidence whatever that Moses ever wrote this chapter or knew anything about it.” This allegation is not creditable to the judgment of the lecturer.
The Genesis is the undoubted work of Moses, as all ancient and modern scholars, both Jew and Christian, testify. If, however, Professor Huxley, upon the authority of his perverse or ignorant critics and of the rationalistic dignitaries of a false church, believes the contrary, it does not follow that the historical method obliged him to substitute the Miltonic theory for the Biblical history under pain of “entangling himself in a vexed question.” If there was a vexed question, he could discard it with a word. Nothing prevented him from speaking of “what is styled the Mosaic doctrine.” The truth is that the professor labored all along to demolish the Mosaic doctrine under the name of Miltonic hypothesis, thinking, no doubt, that by this artifice he might just say enough to satisfy his friends the free-thinkers, without shocking too violently the public mind. The artifice, however, proved unsuccessful; and if the professor has seen the criticism passed on his lectures by the American press, he must now have acquired the conviction that the Miltonic hypothesis did not deserve the honor of a scientific refutation.
In his second lecture Mr. Huxley begins to deal with the evidences of evolution. He points out that
such evidences are of three kinds—viz., indifferent, favorable, and demonstrative. The first two kinds he is prepared to examine at once, whilst the third he keeps in reserve for his last lecture. One might ask what an “indifferent evidence” is likely to mean. For, if any fact has no greater tendency to prove than to disprove a theory, such a fact does not constitute “evidence” on either side. This, of course, is true; but, in the language of the professor, “indifferent evidence” designates those facts which are brought against his theory, and which he believes to admit of a satisfactory explanation without abandoning the theory. Thus he relates how
“Cuvier endeavored to ascertain by a very just and proper method what foundation there was for the belief in a gradual and progressive change of animals, by comparing the skeletons of all accessible parts of these animals (old Egyptian remains)—such as crocodiles, birds, dogs, cats, and the like—with those which are now found in Egypt; and he came to the conclusion—a conclusion which has been verified by all subsequent research—that no appreciable change has taken place in the animals which inhabited Egypt, and he drew thence the conclusion, and a hasty one, that the evidence of such fact was altogether against the doctrine of evolution.”
Again, the professor states that the animal remains deposited in the beds of stone lining the Niagara “belong to exactly the same forms as now inhabit the still waters of Lake Erie”; and these remains, according to his calculation, are more than thirty thousand years old. Again:
“When we examine the rocks of the cretaceous epoch itself, we find the remains of some animals which the closest scrutiny cannot show to be in any respect different from those which live at the present time.” “More than that:
At the very bottom of the Silurian series, in what is by some authorities termed the Cambrian formation, where all signs appear to be dying out, even there, among the few and scanty animal remains which exist, we find species of molluscous animals which are so closely allied to existing forms that at one time they were grouped under the same generic name.… Facts of this kind are undoubtedly fatal to any form of evolution which necessitates the supposition that there is an intrinsic necessity on the part of animal forms which once come into existence to undergo modifications; and they are still more distinctly opposed to any view which should lead to the belief that the modification in different types of animal or vegetable life goes on equally and evenly. The facts, as I have placed them before you, would obviously contradict directly any such form of the hypothesis of evolution as laid down in these two postulates.”
Here, then, we have facts which “contradict directly” any form of necessary evolution. Now let us see how the professor strives to turn them into indifferent evidences of spontaneous evolution. He says:
“Now, the service that has been rendered by Mr. Darwin to the doctrine of evolution in general is this: that he has shown that there are two great factors in the process of evolution, and one of them is the tendency to vary, the existence of which may be proved by observation in all living forms; the other is the influence of surrounding conditions upon what I may call the parent form and the variations which are thus evolved from it. The cause of that production of variations is a matter not at all properly understood at present. Whether it depends upon some intricate machinery—if I may use the phrase—of the animal form itself, or whether it arises through the influence of conditions upon that form, is not certain, and the question may for the present be left open. But the important point is the tendency to the production of variations. Then whether those variations shall survive and supplant the parent, or whether the parent form shall survive and supplant the variations, is a matter which depends entirely on surrounding conditions.”
