But the whole question concerning the freedom of the will has now come to be as to whether or not consciousness does give its verdict on the side of freedom. Supposing we grant that "we are warranted to rely on a deliverance of consciousness, when that deliverance is that a thing is, although we may be unable to think how it can be,"[[12]] in this case the question still remains, whether our opponents have rightly interpreted the deliverance of their consciousness. I, for one, am quite persuaded that I never perform any action without some appropriate motive, or set of motives, having induced me to perform it. However, I am not discussing this question, and I have merely made the above quotations for the purpose of showing that Sir W. Hamilton appears to identify the theory of Free-will with the fact that we possess a moral sense. He argues throughout as though the theory he advocates were the only one that can explain a given "fact of real actuality." But no one with whom we have to deal questions the fact of our having a moral sense; and to identify this "deliverance of consciousness" with belief in the theory that volitions are uncaused, is, or would now be, merely to abandon the only questions in dispute.
It is very instructive, from this point of view, to observe the dilemma into which Hamilton found himself driven by this identification of genuine fact with spurious theory. He believed that the fact of man possessing an ethical faculty could only be explained by the theory that man's will was not determined by motives; for otherwise man could not be the author of his own actions. But when he considered the matter in its other aspect, he found that his theory of Free-will was as little compatible with moral responsibility as was the opposing theory of "Bond-will;" for not only did he candidly confess that he could not conceive of will as acting without motives, but he further allowed the unquestionable truth "that, though inconceivable, a motiveless volition would, if conceived, be conceived as morally worthless."[[13]] I say this is very instructive, because it shows that in Hamilton's view each theory was alike irreconcilable with "the deliverance of consciousness," and that he only chose the one in preference to the other, because, although not any more conceivable a solution, it seemed to him a more possible one.[[14]]
[§ 21]. Such, then, is the speculative basis on which, according to Sir W. Hamilton, our belief in a Deity can alone be grounded.
Those who at the present day are still confused enough in their notions regarding the Free-will question to suppose that any further rational question remains, may here be left to ruminate over this bolus, and to draw from it such nourishment as they can in support of their belief in a God; but to those who can see as plainly as daylight that the doctrine of Determinism not only harmonises with all the facts of observation, but alone affords a possible condition for, and a satisfactory explanation of, the existence of our ethical faculty,—to such persons the question will naturally arise:—"Although Hamilton was wrong in identifying a known fact with a false theory, yet may he not have been right in the deductions which he drew from the fact?" In other words, granting that his theory of Free-will was wrong, does not his argument from the existence of a moral sense in man to the existence of a moral Governor of the Universe remain as intact as ever? Now, it is quite true that whatever degree of cogency the argument from the presence of the moral sense may at any time have had, this degree remains unaffected by the explosion of erroneous theories to account for such presence. We have, therefore, still to face the fact that the moral sense of man undoubtedly exists.
[§ 22]. The question we have to determine is, What evidence have we to show that the moral part of man was created in the image of God; and if there is any such evidence, what counter-existence is there to show that the moral existence of man may be due to natural causes? In deciding this question, just as in deciding any other question of a purely scientific character, we must be guided in our examination by the Law of Parcimony; we must not assume the agency of supernatural causes if we can discover the agency of natural causes; neither must we merge the supposed mystery directly into the highest mystery, until we are quite sure that it does not admit of being proximately explained by the action of proximate influences.
Now, whether or not Mr. Darwin's theory as to the origin and development of the moral sense be considered satisfactory, there can, I think, be very little doubt in any impartial mind which duly considers the subject, that in some way or other the moral sense has been evolved. The body of scientific evidence which has now been collected in favour of the general theory of evolution is simply overwhelming; and in the presence of so large an analogy, it would require a vast amount of contradictory evidence to remove the presumption that human conscience, like everything else, has been evolved. Now, for my own part, I am quite unable to distinguish any such evidence, while, on the other hand, in support of the à priori presumption that conscience has been evolved, I cannot conceal from myself that there is a large amount of à posteriori confirmation. I am quite unable to distinguish anything in my sense of right and wrong which I cannot easily conceive to have been brought about during the evolution of my intelligence from lower forms of psychical life. On the contrary, everything that I can find in my sense of right and wrong is precisely what I should expect to find on the supposition of this sense having been moulded by the progressive requirements of social development. Read in the light of evolution, Conscience, in its every detail, is deductively explained.
And, as though there were not sufficient evidence of this kind to justify the conclusion drawn from the theory of evolution, the doctrine of utilitarianism—separately conceived and separately worked out on altogether independent grounds—the doctrine of utilitarianism comes in with irresistible force to confirm that à priori conclusion by the widest and most unexceptionable of inductions.[[15]]
In the supernatural interpretation of the facts, the whole stress of the argument comes upon the character of conscience as a spontaneously admonishing influence which acts independently of our own volition. For it is from this character alone that the inference can arise that conscience is the delegate of the will of another. Thus, to render the whole argument in the singularly beautiful words of Dr. Newman:—"If, as is the case, we feel responsibility, are ashamed, are frightened at transgressing the voice of conscience, this implies that there is One to whom we are responsible, before whom we are ashamed, whose claims upon us we fear. If, on doing wrong, we feel the same tearful, broken-hearted sorrow which overwhelms us on hurting a mother; if, on doing right, we enjoy the same seeming serenity of mind, the same soothing, satisfactory delight, which follows on one receiving praise from a father,—we certainly have within us the image of some person to whom our love and veneration look, in whose smile we find our happiness, for whom we yearn, towards whom we direct our pleadings, in whose anger we waste away. These feelings in us are such as require for their exciting cause an intelligent being; we are not affectionate towards a stone, nor do we feel shame before a horse or a dog; we have no remorse or compunction in breaking mere human law. Yet so it is; conscience emits all these painful emotions, confusion, foreboding, self-condemnation; and, on the other hand, it sheds upon us a deep peace, a sense of security, a resignation, and a hope which there is no sensible, no earthly object to elicit. 'The wicked flees when no one pursueth;' then why does he flee? whence his terror? Who is it that he sees in solitude, in darkness, in the hidden chambers of his heart? If the cause of these emotions does not belong to this visible world, the Object to which his perception is directed must be supernatural and divine; and thus the phenomena of conscience as a dictate avail to impress the imagination with the picture of a Supreme Governor, a Judge, holy, just, powerful, all-seeing, retributive."[[16]]
Now I have quoted this passage because it seems to me to convey in a concise form the whole of the argument from Conscience. But how tremendous are the inferences which are drawn from the facts! As the first step in our criticism, it is necessary to point out that two very different orders of feelings are here treated by Dr. Newman. There is first the pure or uncompounded ethical feelings, which spring directly from the moral sense alone, and which all men experience in varying degrees. And next there are what we may term the ethico-theological feelings, which can only spring from a blending of the moral sense with a belief in a personal God, or other supernatural agents. The former class of feelings, or the uncompounded ethical class, have exclusive reference to the moral obligations that subsist between ourselves and other human beings, or sentient organisms. The latter class of feelings, or the ethico-theological class, have reference to the moral obligations that are believed to subsist between ourselves and the Deity, or other supernatural beings. Now, in order not to lose sight of this all-important distinction, I shall criticise Dr. Newman's rendering of the ordinary argument from Conscience in each of these two points of views separately. To begin, then, with the uncompounded ethical feelings.
Such emotions as attend the operation of conscience in those who follow its light alone without any theories as to its supernatural origin, are all of the character of reasonable or explicable emotions. Granting that fellow-feeling has been for the benefit of the race, and therefore that it has been developed by natural causes, certainly there is nothing mysterious in the emotions that attend the violating or the following of the dictates of conscience. For conscience is, by this naturalistic supposition, nothing more than an organised body of certain psychological elements, which, by long inheritance, have come to inform us, by way of intuitive feeling, how we should act for the interests of society; so that, if this hypothesis is correct, there cannot be anything more mysterious or supernatural in the working of conscience than there is in the working of any of our other faculties. That the disagreeable feeling of self-reproach, as distinguished from religious feeling, should follow upon a violation of such an organized body of psychological elements, cannot be thought surprising, if it is remembered that one of these elements is natural fellow-feeling, and the others the elements which lead us to know directly that we have violated the interests of other persons. And as regards the mere fact that the working of conscience is independent of the will, surely this is not more than we find, in varying degrees, to be true of all our emotions; and conscience, according to the evolution theory, has its root in the emotions. Hence, it is no more an argument to say that the irrepressible character of conscience refers us to a God of morality, than it would be to say that the sometimes resistless force of the ludicrous refers us to a god of laughter. Love, again, is an emotion which cannot be subdued by volition, and in its tendency to persist bears just such a striking resemblance to the feelings of morality as we should expect to find on the supposition of the former having played an important part in the genesis of the latter. The dictating character of conscience, therefore, is clearly in itself of no avail as pointing to a superhuman Dictator. Thus, for example, to take Dr. Newman's own illustration, why should we feel such tearful, broken-hearted sorrow on intentionally or carelessly hurting a mother? We see no shadow of a reason for resorting to any supernatural hypothesis to explain the fact—love between mother and offspring being an essential condition to the existence of higher animals. Yet this is a simple case of truly conscientious feeling, where the thought of any personal cause of conscience need not be entertained, and is certainly not necessary to explain the effects. And similarly with all cases of conscientious feeling, except in cases where it refers directly to its supposed author. But these latter cases, or the ethico-theological class of feelings, are in no way surprising. If the moral sense has had a natural genesis in the actual relations between man and man, as soon as an ideal "image" of "a holy, just, powerful, all-seeing, retributive" God is firmly believed to have an objective existence, as a matter of course moral feelings must become transferred to the relations which are believed to obtain between ourselves and this most holy God. Indeed, it is these very feelings which, in the absence of any proof to the contrary, must be concluded, in accordance with the law of parcimony, to have generated this idea of God as "holy, just," and good. And the mere fact that, when the complex system of religious belief has once been built up, conscience is strongly wrought upon by that belief and its accompanying emotions, is surely a fact the very reverse of mysterious. Suppose, for the sake of argument, that the moral sense has been evolved from the social feelings, and should we not certainly expect that, when the belief in a moral and all-seeing God is superadded, conscience should be distracted at the thought of offending him, and experience a "soothing, satisfactory delight" in the belief that we are pleasing him? And as to the argument, "Why does the wicked flee when none pursueth? whence his terror?" the question admits of only too easy an answer. Indeed, the form into which the question is thrown would almost seem—were it not written by Dr. Newman—to imply a sarcastic reference to the power of superstition. "Who is it that," not only Dr. Newman, but the haunted savage, the mediæval sorcerer, or the frightened child, "sees in solitude, in darkness, in the hidden chambers of his heart?" Who but the "image" of his own thought? "If the cause of these emotions does not belong to this visible world, the Object to which his perception is directed must be supernatural and divine." Assuredly; but what an inference from what an assumption! Whether or not the moral sense has been developed by natural causes, "these emotions" of terror at the thought of offending beings "supernatural and divine" are not of such unique occurrence "in the visible world" as to give Dr. Newman the monopoly of his particular "Object." With a deeper meaning, therefore, than he intends may we repeat, "The phenomena of conscience as a dictate avail to impress the imagination with the picture of a Supreme Governor." But criticism here is positively painful. Let it be enough to say that those of us who do not already believe in any such particular "Object"—be it ghost, shape, demon, or deity—are strangers, utter and complete, to any such supernatural pursuers. The fact, therefore, of these various religious emotions being associated with conscience in the minds of theists, can in itself be no proof of Theism, seeing that it is the theory of Theism which itself engenders these emotions; those who do not believe in this theory experiencing none of these feelings of personal dread, responsibility to an unknown God, and the feelings of doing injury to, or of receiving praise from, a parent. To such of us the violation of conscience is its own punishment, as the pursuit of virtue is its own reward. For we know that not more certainly than fire will burn, any violation of the deeply-rooted feelings of our humanity will leave a gaping wound which even time may not always heal. And when it is shown us that our natural dread of fire is due to a supernatural cause, we may be prepared to entertain the argument that our natural dread of sin, as distinguished from our dread of God, is likewise due to such a cause. But until this can be done we must, as reasonable men, whose minds have been trained in the school of nature, forbear to allow that the one fact is of any greater cogency than the other, so far as the question of a supernatural cause of either is concerned. For, as we have already seen, the law of parcimony forbids us to ascribe "the phenomena of conscience as a dictate" to a supernatural cause, until the science of psychology shall have proved that they cannot have been due to natural causes. But, as we have also seen, the science of psychology is now beginning, as quick and thoroughly as can be expected, to prove the very converse; so that the probability is now overwhelming that our moral sense, like all our other faculties, has been evolved. Therefore, while the burden of proof really lies on the side of Theism—or with those who account for the natural phenomena of conscience by the hypothesis of a supernatural origin—this burden is now being rapidly discharged by the opposite side. That is to say, while the proofs which are now beginning to substantiate the naturalistic hypothesis are all in full accord with the ordinary lines of scientific explanations, the vague and feeble reflections of those who still maintain that Conscience is evidence of Deity, are all such as run counter to the very truisms of scientific method.
