THE ARGUMENT FROM GENERAL LAWS.

[§ 28]. Turning now to an important error of Mr. Mill's in respect of omission, I firmly believe that all competent writers who have ever undertaken to support the argument from Design, have been moved to do so by their instinctive appreciation of the much more important argument, which Mill does not mention at all and which we now proceed to consider—the argument from General Laws. That is to say, I cannot think that any one competent writer ever seriously believed, had he taken time to analyse his beliefs, that the cogency of his argument lay in assuming any knowledge concerning the process of divine thought; he must have really believed that it lay entirely in his observation of the product of divine thought—or rather, let us say, of divine intelligence. Now this is the whole difference between the argument from Design and the argument from General Laws. The argument from Design says, There must be a God, because such and such an organic structure must have been due to such and such an intellectual process. The argument from General Laws says, There must be a God, because such and such an organic structure must in some way or other have been ultimately due to intelligence. Nor does this argument end here. Not only must such and such an organic structure have been ultimately due to intelligence, but every such structure—nay, every phenomenon in the universe—must have been the same; for all phenomena are alike subject to the same method of sequence. The argument is thus a cumulative one; for as there is no single known exception to this universal mode of existence, the united effect of so vast a body of evidence is all but irresistible, and its tendency is clearly to point us to some one explanatory cause. The scope of this argument is therefore co-extensive with the universe; it draws alike upon all phenomena with which experience is acquainted. For instance, it contains all the phenomena covered by the Design argument, just as a genus contains any one of its species; it being manifest, from what was said in the last section, that if the general doctrine of Evolution is accepted, the argument from Design must of necessity merge into that from General Laws. And this wide basis, we may be sure, must be the most legitimate one whereon to rest an argument in favour of Theism. If there is any such thing as such an argument at all, the most unassailable field for its display must be the universe as a whole, seeing that if we separate any one section of the universe from the rest, and suppose that we here discover a different kind of testimony to intelligence from that which we can discover elsewhere, we may from analogy be abundantly sure that on the confines of our division there must be second causes and general laws at work (whether discoverable or not), which are the immediate agents in the production of the observed results. Of course I do not deny that some classes of phenomena afford us more and better proofs of intellectual agency than do others, in the sense of the laws in operation being more numerous, subtle, and complex; but it will be seen that this is a different interpretation of the evidence from that against which I am contending. Thus, if there are tokens of divine intention (as distinguished from design) to be met with in the eye,—if it is inconceivable that so "nice and intricate a structure" should exist without intelligence as its ultimate cause; then the discovery of natural selection, or of any other law, as the manner in which this intelligence wrought in no wise attenuates the proof as to the fact of an intelligent cause. On the contrary, it tends rather to confirm it; for, besides the evidence before existing, there is added that which arises from the conformity of the method to that which is observable in the rest of the universe.

Thus, notwithstanding what Hamilton, Chalmers, and others have said, I cannot but feel that the ubiquitous action of general laws is, of all facts supplied by experience, the most cogent in its bearing upon teleology. If perpetual and uninterrupted uniformity of method does not indicate the existence of a presiding intelligence, it becomes a question whether any other kind of method—short of the intelligently miraculous—could possibly do so; seeing that the further the divine modus operandi (supposing such to exist) were removed from absolute uniformity, the greater would be the room for our interpreting it as mere fortuity. But forasmuch as the progress of science has shown that within experience the method of the Supreme Causality is absolutely uniform, the hypothesis of fortuity is rendered irrational; and let us think of this Supreme Causality as we may, the fact remains that from it there emanates a directive influence of uninterrupted consistency, on a scale of stupendous magnitude and exact precision, worthy of our highest possible conceptions of Deity.

[§ 29]. Had it been my lot to have lived in the last generation, I doubt not that I should have regarded the foregoing considerations as final: I should have concluded that there was an overwhelming balance of rational probability in favour of Theism; and I think I should also have insisted that this balance of rational probability would require to continue as it was till the end of time. I should have maintained, in some such words as the following, in which the Rev. Baden Powell conveys this argument:—"The very essence of the whole argument is the invariable preservation of the principle of order: not necessarily such as we can directly recognise, but the universal conviction of the unfailing subordination of everything to some grand principles of law, however imperfectly apprehended in our partial conceptions, and the successive subordination of such laws to others of still higher generality, to an extent transcending our conceptions, and constituting the true chain of universal causation which culminates in the sublime conception of the Cosmos.

"It is in immediate connection with this enlarged view of universal immutable natural order that I have regarded the narrow notions of those who obscure the sublime prospect by imagining so unworthy an idea as that of occasional interruptions in the physical economy of the world.

"The only instance considered was that of the alleged sudden supernatural origination of new species of organised beings in remote geological epochs. It is in relation to the broad principle of law, if once rightly apprehended, that such inferences are seen to be wholly unwarranted by science, and such fancies utterly derogatory and inadmissible in philosophy; while, even in those instances properly understood, the real scientific conclusions of the invariable and indissoluble chain of causation stand vindicated in the sublime contemplations with which they are thus associated.

"To a correct apprehension of the whole argument, the one essential requisite is to have obtained a complete and satisfactory grasp of this one grand principle of law pervading nature, or rather constituting the very idea of nature;—which forms the vital essence of the whole of inductive science, and the sole assurance of those higher inferences from the inductive study of natural causes which are the vindications of a supreme intelligence and a moral cause.

"The whole of the ensuing discussion must stand or fall with the admission of this grand principle. Those who are not prepared to embrace it in its full extent may probably not accept the conclusions; but they must be sent back to the school of inductive science, where alone it must be independently imbibed and thoroughly assimilated with the mind of the student in the first instance.

"On the slightest consideration of the nature, the foundations, and general results of inductive science,... we recognise the powers of intellect fitly employed in the study of nature,... pre-eminently leading us to perceive in nature, and in the invariable and universal constancy of its laws, the indications of universal, unchangeable, and recondite arrangement, dependence, and connection in reason....
