[§ 40]. I have purposely rendered this presentation in terms of the highest abstraction, partly to avoid the possibility of any one, whatever his theory of things may be, finding anything at which to object, and partly in order that my meaning may be understood to include all things which are beyond the range of possible knowledge. Most of all, therefore, must this presentation (if it contains anything of truth) apply to the question regarding the existence of Deity; for the Ens Realissimum must of all things be furthest removed from the range of possible knowledge. Hence, if this presentation contains anything of truth—and of its rigidly accurate truth I think there can be no question—the assertion that the Self-existing Substance is a Personal and Intelligent Being, and the assertion that this Substance is an Impersonal and Non-Intelligent Being, are alike assertions wholly destitute of any assignable degree of logical probability, I say assignable degree of logical probability, because that some degree of such probability may exist I do not undertake to deny. All I assert is, that if we are here able to institute any such probability at all, we are unable logically to assign to it any determinate degree of value. Or, in other words, although we may establish some probability in a sense relative to ourselves, we are unable to know how far this probability is a probability in an absolute sense. Or again, the case is not as though we were altogether unacquainted with the Possible. Experience undoubtedly affords us some information regarding this, although, comparatively speaking, we are unable to know how much. Consequently, we must suppose that, in any given case, it is more likely that the Conceivable should be Possible than that the Inconceivable should be so, and that the Conceivably Probable should exist than that the Conceivably Improbable should do so: in neither case, however, can we know what degree of such likelihood is present.
[§ 41]. From the foregoing considerations, then, it would appear that the only attitude which in strict logic it is admissible to adopt towards the question concerning the being of a God is that of "suspended judgment." Formally speaking, it is alike illegitimate to affirm or to deny Intelligence as an attribute of the Ultimate. And here I would desire it to be observed, that this is the attitude which the majority of scientifically-trained philosophers actually have adopted with regard to this matter. I am not aware, however, that any one has yet endeavoured to formulate the justification of this attitude; and as I think there can be no doubt that the above presentation contains in a logical shape the whole of such justification, I cannot but think that some important ends will have been secured by it. For we are here in possession, not merely of a vague and general impression that the Ultimate is super-scientific, and so beyond the range of legitimate prediction; but we are also in possession of a logical formula whereby at once to vindicate the rationality of our opinion, and to measure the precise degree of its technical value.
[CHAPTER VI].
THE ARGUMENT FROM METAPHYSICAL TELEOLOGY.
[§ 42]. Let us now proceed to examine the effect of the formal considerations which have been adduced in the last chapter on the scientific considerations which were dealt with in the previous chapters. In these previous chapters the proposition was clearly established that, just as certainly as the fundamental data of science are true, so certainly is it true that the theory of Theism in any shape is, scientifically considered, superfluous; for these chapters have clearly shown that, if there is a God, his existence, considered as a cause of things, is as certainly unnecessary as it is certainly true that force is persistent and that matter is indestructible. But after this proposition had been carefully justified, it remained to show that the doctrine of the relativity of knowledge compelled us to carry our discussion into a region of yet higher abstraction. For although we observed that the essential qualities of matter and of force are the most ultimate data of human knowledge, and although, by showing how far the question of Theism depended on these data, we carried the discussion of that question to the utmost possible limits of scientific thought, it still devolved on us to contemplate the fact that even these the most ultimate data of science are only known to be of relative significance. And the bearing of this fact to the question of Theism was seen to be most important. For, without waiting to recapitulate the substance of a chapter so recently concluded, it will be remembered that its effect was to establish this position beyond all controversy—viz., that when ideas which have been formed by our experience within the region of phenomenal actuality are projected into the region of ontological possibility, they become utterly worthless; seeing that we can never have any means whereby to test the actual value of whatever transcendental probabilities they may appear to establish. Therefore it is that even the most ultimate of relative truths with which, as we have seen, the question of Theism is so vitally associated, is almost without meaning when contemplated in an absolute sense. What, then, is the effect of these metaphysical considerations on the position of Theism as we have seen it to be left by the highest generalisations of physical science? Let us contemplate this question with the care which it deserves.
In the first place, it is evident that the effect of these purely formal considerations is to render all reasonings on the subject of Theism equally illegitimate, unless it is constantly borne in mind that such reasonings can only be of relative signification. Thus, as a matter of pure logic, these considerations are destructive of all assignable validity of any such reasoning whatsoever. Still, even a strictly relative probability is, in some undefinable degree, of more value than no probability at all, as we have seen these same formal considerations to show (see [§ 40]); and, moreover, even were this not so, the human mind will never rest until it attains to the furthest probability which to its powers is accessible. Therefore, if we do not forget the merely relative nature of the considerations which are about to be adduced, by adducing them we may at the same time satisfy our own minds and abstain from violating the conditions of sound logic.
The shape, then, to which the subject has now been reduced is simply this:—Seeing that the theory of Evolution in its largest sense has shown the theory of Theism to be superfluous in a scientific sense, does it not follow that the theory of Theism is thus shown to be superfluous in any sense? For it would seem from the discussion, so far as it has hitherto gone, that the only rational basis on which the theory of Theism can rest is a basis of teleology; and if, as has been clearly shown, the theory of evolution, by deducing the genesis of natural law from the primary data of science, irrevocably destroys this basis, does it not follow that the theory of evolution has likewise destroyed the theory which rested on that basis? Now I conclude, as stated at the close of [Chapter IV.,] that the question here put must certainly be answered in the affirmative, so far as its scientific aspect is concerned. But when we consider the question in its purely logical aspect, as we have done in [Chapter V.,] the case is otherwise. For although, so far as the utmost reach of scientific vision enables us to see, we can discern no evidence of Deity, it does not therefore follow that beyond the range of such vision Deity does not exist. Science indeed has proved that if there is a Divine Mind in nature, and if by the hypothesis such a Mind exerts any causative influence on the phenomena of nature, such influence is exerted beyond the sphere of experience. And this achievement of science, be it never forgotten, is an achievement of prodigious importance, effectually destroying, as it does, all vestiges of a scientific teleology. But be it now carefully observed, although all vestiges of a scientific teleology are thus completely and permanently ruined, the formal considerations adduced in the [last chapter] supply the conditions for constructing what may be termed a metaphysical teleology. I use these terms advisedly, because I think they will serve to bring out with great clearness the condition to which our analysis of the teleological argument has now been reduced.
[§ 43]. In the first place, let it be understood that I employ the terms "scientific" and "metaphysical" in the convenient sense in which they are employed by Mr. Lewes, viz., as respectively designating a theory that is verifiable and a theory that is not. Consequently, by the term "scientific teleology" I mean to denote a form of teleology which admits either of being proved or disproved, while by the term "metaphysical teleology" I mean to denote a form of teleology which does not admit either of being proved or of being disproved. Now, with these significations clearly understood, it will be seen that the forms of teleology which we have hitherto considered belong entirely to the scientific class. That the Paleyerian form of the argument did so is manifest, first because this argument itself treats the problem of Theism as a problem that is susceptible of scientific demonstration, and next because we have seen that the advance of science has proved this argument susceptible of scientific refutation. In other words, from the supposed axiom, "There cannot be apparent design without a designer," adaptations in nature become logically available as purely scientific evidence of an intelligent cause; and that Paley himself regarded them exclusively in this light is manifest, both from his own "statement of the argument," and from the character of the evidence by which he seeks to establish the argument when stated—witness the typical passage before quoted ([§ 26]). On the other hand, we have clearly seen that this Paleyerian system of natural theology has been effectually demolished by the scientific theory of natural selection—the fundamental axiom of the former having been shown by the latter to be scientifically untrue. Hence the term "scientific teleology" is without question applicable to the Paleyerian system.
Nor is the case essentially different with the more refined form of the teleological argument which we have had to consider—the argument, namely, from General Laws. For here, likewise, we have clearly seen that the inference from the ubiquitous operation of General Laws to the existence of an omniscient Law-maker is quite as illegitimate as is the inference from apparent Design to the existence of a Supreme Designer. In other words, science, by establishing the doctrine of the persistence of force and the indestructibility of matter, has effectually disproved the hypothesis that the presence of Law in nature is of itself sufficient to prove the existence of an intelligent Law-giver.
