A Candid Examination of Theism

by George John Romanes

Thus it is that scientific teleology in any form is now and for ever obsolete. But not so with what I have termed metaphysical teleology. For as we have seen that the doctrine of the relativity of knowledge precludes us from asserting, or even from inferring, that beyond the region of the Knowable Mind does not exist, it remains logically possible to institute a metaphysical hypothesis that beyond this region of the Knowable Mind does exist. There being a necessary absence of any positive information whereby to refute this metaphysical hypothesis, any one who chooses to adopt it is fully justified in doing so, provided only he remembers that the purely metaphysical quality whereby the hypothesis is ensured against disproof, likewise, and in the same degree, precludes it from the possibility of proof. He must remember that it is no longer open to him to point to any particular set of general laws and to assert, these proclaim Intelligence as their cause; for we have repeatedly seen that the known states of matter and force themselves afford sufficient explanation of the facts to which he points. And he must remember that the only reason why his hypothesis does not conflict with any of the truths known to science, is because he has been careful to rest that hypothesis upon a basis of purely formal considerations, which lie beyond even the most fundamental truths of which science is cognisant.

Thus, for example, he may present his metaphysical theory of Theism in some such terms as these:—'Fully conceding what reason shows must be conceded, and there still remains this possible supposition—viz., that there is a presiding Mind in nature, which exerts its causative influence beyond the sphere of experience, thus rendering it impossible for us to obtain scientific evidence of its action. For such a Mind, exerting such an influence beyond experience, may direct affairs within experience by methods conceivable or inconceivable to us—producing, possibly, innumerable and highly varied results, which in turn may produce their effects within experience, their introduction being then, of course, in the ordinary way of natural law. For instance, there can be no question that by the intelligent creation or dissipation of energy, all the phenomena of cosmic evolution might have been directed, and, for aught that science can show to the contrary, thus only rendered possible. Hence there is at least one nameable way in which, even in accordance with observed facts, a Supreme Mind could be competent to direct the phenomena of observable nature. But we are not necessarily restricted to the limits of the nameable in this matter, so that it is of no argumentative importance whether or not this suggested method is the method which the supposed Mind actually adopts, seeing that there may still be other possible methods, which, nevertheless, we are unable to suggest.'

Doubtless the hypothesis of Theism, as thus presented, will be deemed by many persons but of very slender probability. I am not, however, concerned with whatever character of probability it may be supposed to exhibit. I am merely engaged in carefully presenting the only hypothesis which can be presented, if the theory as to an Intelligent Author of nature is any longer to be maintained on grounds of a rational teleology. No doubt, scientifically considered, the hypothesis in question is purely gratuitous; for, so far as the light of science can penetrate, there is no need of any such hypothesis at all. Thus it may well seem, at first sight, that no hypothesis could well have less to recommend it; and, so far as the presentation has yet gone, it is therefore fully legitimate for an atheist to reply:—'All that this so-called metaphysical theory amounts to is a wholly gratuitous assumption. No doubt it is always difficult, and usually impossible, logically or unequivocally to prove a negative. If my adversary chose to imagine that nature is presided over by a demon with horns and hoofs, or by a dragon with claws and tail, I should be as unable to disprove this his supposed theory as I am now unable to disprove his actual theory. But in all cases reasonable men ought to be guided in their beliefs by such positive evidence as is available; and if, as in the present case, the alternative belief is wholly gratuitous—adopted not only without any evidence, but against all that great body of evidence which the sum-total of science supplies—surely we ought not to hesitate for one moment in the choice of our creed?'

Now all this is quite sound in principle, provided only that the metaphysical theory of Theism is wholly gratuitous, in the sense of being utterly destitute of evidential support. That it is destitute of all scientific support, we have already and repeatedly seen; but the question remains as to whether it is similarly destitute of metaphysical support.

[§ 44]. To this question, then, let us next address ourselves. From the theistic pleading which we have just heard, it is abundantly manifest that the formal conditions of a metaphysical teleology are present: the question now before us is as to whether or not any actual evidence exists in favour of such a theory. In order to discuss this question, let us begin by allowing the theist to continue his pleading. 'You have shown me,' he may say, 'that a scientific or demonstrable system of teleology is no longer possible, and, therefore, as I have already conceded, I must take my stand on a metaphysical or non-demonstrable system. But I reflect that the latter term is a loose one, seeing that it embraces all possible degrees of evidence short of actual proof. The question, therefore, I conceive to be, What amount of evidence is there in favour of this metaphysical system of teleology? And this question I answer by the following considerations:—As general laws separately have all been shown to be the necessary outcome of the primary data of science, it certainly follows that general laws collectively must be the same—i.e., that the whole system of general laws must be, so far as the lights of our science can penetrate, the necessary outcome of the persistence of force and the indestructibility of matter. But you have also dearly shown me that these lights are of the feeblest conceivable character when they are brought to illuminate the final mystery of things. I therefore feel at liberty to assert, that if there is any one principle to be observed in the collective operation of general laws which cannot conceivably be explained by any cause other than that of intelligent guidance, I am still free to fall back on such a principle and to maintain—Although the collective operation of general laws follows as a necessary consequence from the primary data of science, this one principle which pervades their united action, and which cannot be conceivably explained by any hypothesis other than that of intelligent guidance, is a principle which still remains to be accounted for; and as it cannot conceivably be accounted for on grounds of physical science, I may legitimately account for it on grounds of metaphysical teleology. Now I cannot open my eyes without perceiving such a principle everywhere characterising the collective operation of general laws. Universally I behold in nature, order, beauty, harmony,—that is, a perfect correlation among general laws. But this ubiquitous correlation among general laws, considered as the cause of cosmic harmony, itself requires some explanatory cause such as the persistence of force and the indestructibility of matter cannot conceivably be made to supply. For unless we postulate some one integrating cause, the greater the number of general laws in nature, the less likelihood is there of such laws being so correlated as to produce harmony by their combined action. And forasmuch as the only cause that I am able to imagine as competent to produce such effects is that of intelligent guidance, I accept the metaphysical hypothesis that beyond the sphere of the Knowable there exists an Unknown God.[^[25]]

'If it is retorted that the above argument involves an absurd contradiction, in that while it sets out with an explicit avowal of the fact that the collective operation of general laws follows as a necessary consequence from the primary data of physical science, it nevertheless afterwards proceeds to explain an effect of such collective operation by a metaphysical hypothesis; I answer that it was expressly for the purpose of eliciting this retort that I threw my argument into the above form. For the position which I wish to establish is this, that fully accepting the logical cogency of the reasoning whereby the action of every law is deduced from the primary data of science, I wish to show that when this train of reasoning is followed to its ultimate term, it leads us into the presence of a fact for which it is inadequate to account. If, then, my contention be granted—viz., that to human faculties it is not conceivable how, in the absence of a directing intelligence, general laws could be so correlated as to produce universal harmony—then I have brought the matter to this issue:—Notwithstanding the scientific train of argument being complete in itself, it still leaves us in the presence of a fact which it cannot conceivably explain; and it is this unexplained residuum—this total product of the operation of general laws—that I appeal to as the logical justification for a system of metaphysical teleology—a system which offers the only conceivable explanation of this stupendous fact.

'And here I may further observe, that the scientific train of reasoning is of the kind which embodies what Mr. Herbert Spencer calls "symbolic conceptions of the illegitimate order."[^[26]] That is to say, we can see how such simple laws as that action and reaction are equal and opposite may have been self-evolved, and from this fact we go on generalising and generalising, until we land ourselves in wholly symbolic and—a paradox is here legitimate—inconceivable conceptions. Now the farther we travel into this region of unrealisable ideas, the less trustworthy is the report that we are able to bring back. The method is in a sense scientific; but when even scientific method is projected into a region of really super-scientific possibility, it ceases to have that character of undoubted certainty which it enjoys when dealing with verifiable subjects of inquiry. The demonstrations are formal, but they are not real.

'Therefore, looking to this necessarily suspicious character of the scientific train of reasoning, and then observing that, even if accepted, it leaves the fact of cosmic harmony unexplained, I maintain, that whatever probability the phenomena of nature may in former times have been thought to establish in favour of the theory as to an intelligent Author of nature, that probability has been in no wise annihilated—nor apparently can it ever be annihilated—by the advance of science. And not only so, but I question whether this probability has been even seriously impaired by such advance, seeing that although this advance has revealed a speculative raison d'être of the mechanical precision of nature, it has at the same time shown the baffling complexity of nature; and therefore, in view of what has just been said, leaves the balance of probability concerning the existence of a God very much where it always was. For stay awhile to contemplate this astounding complexity of harmonious nature! Think of how much we already know of its innumerable laws and processes, and then think that this knowledge only serves to reveal, in a glimmering way, the huge immensity of the unknown. Try to picture the meshwork of contending rhythms which must have been before organic nature was built up, and then let us ask, Is it conceivable, is it credible, that all this can have been the work of blind fate? Must we not feel that had there not been intelligent agency at work somewhere, other and less terrifically intricate results would have ensued? And if we further try to symbolise in thought the unimaginable complexity of the material and dynamical changes in virtue of which that thought itself exists,—if we then extend our symbols to represent all the history of all the orderly changes which must have taken place to evolve human intelligence into what it is,—and if we still further extend our symbols to try if it be possible, even in the language of symbols, to express the number and the subtlety of those natural laws which now preside over the human will;—in the face of so vast an assumption as that all this has been self-evolved, I am content still to rest in the faith of my forefathers.'

[§ 45]. Now I think it must be admitted that we have here a valid argument. That is to say, the considerations which we have just adduced must, I think, in fairness be allowed to have established this position:—That the system of metaphysical teleology for which we have supposed a candid theist to plead, is something more than a purely gratuitous system—that it does not belong to the same category of baseless imaginings as that to which the atheist at first sight, and in view of the scientific deductions alone, might be inclined to assign it. For we have seen that our supposed theist, while fully admitting the formal cogency of the scientific train of reasoning, is nevertheless able to point to a fact which, in his opinion, lies without that train of reasoning. For he declares that it is beyond his powers of conception to regard the complex harmony of nature otherwise than as a product of some one integrating cause; and that the only cause of which he is able to conceive as adequate to produce such an effect is that of a conscious Intelligence. Pointing, therefore, to this complex harmony of nature as to a fact which cannot to his mind be conceivably explained by any deductions from physical science, he feels that he is justified in explaining this fact by the aid of a metaphysical hypothesis. And in so doing he is in my opinion perfectly justified, at any rate to this extent—that his antagonist cannot fairly dispose of this metaphysical hypothesis as a purely gratuitous hypothesis. How far it is a probable hypothesis is another question, and to this question we shall now address ourselves.

[§ 46]. If it is true that the deductions from physical science cannot be conceived to explain some among the observed facts of nature, and if it is true that these particular facts admit of being conceivably explained by the metaphysical hypothesis in question, then, beyond all controversy, this metaphysical hypothesis must be provisionally accepted. Let us then carefully examine the premises which are thus adduced to justify acceptance of this hypothesis as their conclusion.
