In so far, however, as a knowledge of God’s law is believed to be attainable by the Reason, Ethics and Theology seem to be so closely connected that we cannot sharply separate their provinces. For, as we saw,[379] it has been widely maintained, that the relation of moral rules to a Divine Lawgiver is implicitly cognised in the act of thought by which we discern these rules to be binding. And no doubt the terms (such as ‘moral obligation’), which we commonly use in speaking of these rules, are naturally suggestive of Legal Sanctions and so of a Sovereign by whom these are announced and enforced. Indeed many thinkers since Locke have refused to admit any other meaning in the terms Right, Duty, etc., except that of a rule imposed by a lawgiver. This view, however, seems opposed to Common Sense; as may be, perhaps, most easily shown[380] by pointing out that the Divine Lawgiver is Himself conceived as a Moral Agent; i.e. as prescribing what is right, and designing what is good. It is clear that in this conception at least the notions ‘right’ and ‘good’ are used absolutely, without any reference to a superior lawgiver; and that they are here used in a sense not essentially different from that which they ordinarily bear seems to be affirmed by the consensus of religious persons. Still, though Common Sense does not regard moral rules as being merely the mandates of an Omnipotent Being who will reward and punish men according as they obey or violate them; it certainly holds that this is a true though partial view of them, and perhaps that it may be intuitively apprehended. If then reflection leads us to conclude that the particular moral principles of Common Sense are to be systematised as subordinate to that pre-eminently certain and irrefragable intuition which stands as the first principle of Utilitarianism; then, of course, it will be the Utilitarian Code to which we shall believe the Divine Sanctions to be attached.
Or, again, we may argue thus. If—as all theologians agree—we are to conceive God as acting for some end, we must conceive that end to be Universal Good, and, if Utilitarians are right, Universal Happiness: and we cannot suppose that in a world morally governed it can be prudent for any man to act in conscious opposition to what we believe to be the Divine Design. Hence if in any case after calculating the consequences of two alternatives of conduct we choose that which seems likely to be less conducive to Happiness generally, we shall be acting in a manner for which we cannot but expect to suffer.
To this it has been objected, that observation of the actual world shows us that the happiness of sentient beings is so imperfectly attained in it, and with so large an intermixture of pain and misery, that we cannot really conceive Universal Happiness to be God’s end, unless we admit that He is not Omnipotent. And no doubt the assertion that God is omnipotent will require to be understood with some limitation; but perhaps with no greater limitation than has always been implicitly admitted by thoughtful theologians. For these seem always to have allowed that some things are impossible to God: as, for example, to change the past. And perhaps if our knowledge of the Universe were complete, we might discern the quantum of happiness ultimately attained in it to be as great as could be attained without the accomplishment of what we should then see to be just as inconceivable and absurd as changing the past. This, however, is a view which it belongs rather to the theologian to develop. I should rather urge that there does not seem to be any other of the ordinary interpretations of Good according to which it would appear to be more completely realised in the actual universe. For the wonderful perfections of work that we admire in the physical world are yet everywhere mingled with imperfection, and subject to destruction and decay: and similarly in the world of human conduct Virtue is at least as much balanced by Vice as Happiness is by misery.[381] So that, if the ethical reasoning that led us to interpret Ultimate Good as Happiness is sound, there seems no argument from Natural Theology to set against it.
§ 5. If, then, we may assume the existence of such a Being, as God, by the consensus of theologians, is conceived to be, it seems that Utilitarians may legitimately infer the existence of Divine sanctions to the code of social duty as constructed on a Utilitarian basis; and such sanctions would, of course, suffice to make it always every one’s interest to promote universal happiness to the best of his knowledge. It is, however, desirable, before we conclude, to examine carefully the validity of this assumption, in so far as it is supported on ethical grounds alone. For by the result of such an examination will be determined, as we now see, the very important question whether ethical science can be constructed on an independent basis; or whether it is forced to borrow a fundamental and indispensable premiss from Theology or some similar source.[382] In order fairly to perform this examination, let us reflect upon the clearest and most certain of our moral intuitions. I find that I undoubtedly seem to perceive, as clearly and certainly as I see any axiom in Arithmetic or Geometry, that it is ‘right’ and ‘reasonable’ for me to treat others as I should think that I myself ought to be treated under similar conditions, and to do what I believe to be ultimately conducive to universal Good or Happiness. But I cannot find inseparably connected with this conviction, and similarly attainable by mere reflective intuition, any cognition that there actually is a Supreme Being who will adequately[383] reward me for obeying these rules of duty, or punish me for violating them.[384] Or,—omitting the strictly theological element of the proposition,—I may say that I do not find in my moral consciousness any intuition, claiming to be clear and certain, that the performance of duty will be adequately rewarded and its violation punished. I feel indeed a desire, apparently inseparable from the moral sentiments, that this result may be realised not only in my own case but universally; but the mere existence of the desire would not go far to establish the probability of its fulfilment, considering the large proportion of human desires that experience shows to be doomed to disappointment. I also judge that in a certain sense this result ought to be realised: in this judgment, however, ‘ought’ is not used in a strictly ethical meaning; it only expresses the vital need that our Practical Reason feels of proving or postulating this connexion of Virtue and self-interest, if it is to be made consistent with itself. For the negation of the connexion must force us to admit an ultimate and fundamental contradiction in our apparent intuitions of what is Reasonable in conduct; and from this admission it would seem to follow that the apparently intuitive operation of the Practical Reason, manifested in these contradictory judgments, is after all illusory.
I do not mean that if we gave up the hope of attaining a practical solution of this fundamental contradiction, through any legitimately obtained conclusion or postulate as to the moral order of the world, it would become reasonable for us to abandon morality altogether: but it would seem necessary to abandon the idea of rationalising it completely. We should doubtless still, not only from self-interest, but also through sympathy and sentiments protective of social wellbeing, imparted by education and sustained by communication with other men, feel a desire for the general observance of rules conducive to general happiness; and practical reason would still impel us decisively to the performance of duty in the more ordinary cases in which what is recognised as duty is in harmony with self-interest properly understood. But in the rarer cases of a recognised conflict between self-interest and duty, practical reason, being divided against itself, would cease to be a motive on either side; the conflict would have to be decided by the comparative preponderance of one or other of two groups of non-rational impulses.
If then the reconciliation of duty and self-interest is to be regarded as a hypothesis logically necessary to avoid a fundamental contradiction in one chief department of our thought, it remains to ask how far this necessity constitutes a sufficient reason for accepting this hypothesis. This, however, is a profoundly difficult and controverted question, the discussion of which belongs rather to a treatise on General Philosophy than to a work on the Methods of Ethics: as it could not be satisfactorily answered, without a general examination of the criteria of true and false beliefs. Those who hold that the edifice of physical science is really constructed of conclusions logically inferred from self-evident premises, may reasonably demand that any practical judgments claiming philosophic certainty should be based on an equally firm foundation. If on the other hand we find that in our supposed knowledge of the world of nature propositions are commonly taken to be universally true, which yet seem to rest on no other grounds than that we have a strong disposition to accept them, and that they are indispensable to the systematic coherence of our beliefs,—it will be more difficult to reject a similarly supported assumption in ethics, without opening the door to universal scepticism.
