"When any opinion leads to absurdity, it is certainly false; but it is not certain that an opinion is false because it is of dangerous consequence."—(IV. p. 112.)
And, therefore, that the attempt to refute an opinion by a picture of its dangerous consequences to religion and morality, is as illogical as it is reprehensible.
It is said, in the first place, that necessity destroys responsibility; that, as it is usually put, we have no right to praise or blame actions that cannot be helped. Hume's reply amounts to this, that the very idea of responsibility implies the belief in the necessary connexion of certain actions with certain states of the mind. A person is held responsible only for those acts which are preceded by a certain intention; and, as we cannot see, or hear, or feel, an intention, we can only reason out its existence on the principle that like effects have like causes.
If a man is found by the police busy with "jemmy" and dark lantern at a jeweller's shop door over night, the magistrate before whom he is brought the next morning, reasons from those effects to their causes in the fellow's "burglarious" ideas and volitions, with perfect confidence, and punishes him accordingly. And it is quite clear that such a proceeding would be grossly unjust, if the links of the logical process were other than necessarily connected together. The advocate who should attempt to get the man off on the plea that his client need not necessarily have had a felonious intent, would hardly waste his time more, if he tried to prove that the sum of all the angles of a triangle is not two right angles, but three.
A man's moral responsibility for his acts has, in fact, nothing to do with the causation of these acts, but depends on the frame of mind which accompanies them. Common language tells us this, when it uses "well-disposed" as the equivalent of "good," and "evil-minded" as that of "wicked." If A does something which puts B in a violent passion, it is quite possible to admit that B's passion is the necessary consequence of A's act, and yet to believe that B's fury is morally wrong, or that he ought to control it. In fact, a calm bystander would reason with both on the assumption of moral necessity. He would say to A, "You were wrong in doing a thing which you knew (that is, of the necessity of which you were convinced) would irritate B." And he would say to B, "You are wrong to give way to passion, for you know its evil effects"—that is the necessary connection between yielding to passion and evil.
So far, therefore, from necessity destroying moral responsibility, it is the foundation of all praise and blame; and moral admiration reaches its climax in the ascription of necessary goodness to the Deity.
To the statement of another consequence of the necessarian doctrine, that, if there be a God, he must be the cause of all evil as well as of all good, Hume gives no real reply—probably because none is possible. But then, if this conclusion is distinctly and unquestionably deducible from the doctrine of necessity, it is no less unquestionably a direct consequence of every known form of monotheism. If God is the cause of all things, he must be the cause of evil among the rest; if he is omniscient, he must have the fore-knowledge of evil; if he is almighty, he must possess the power of preventing, or of extinguishing evil. And to say that an all-knowing and all-powerful being is not responsible for what happens, because he only permits it, is, under its intellectual aspect, a piece of childish sophistry; while, as to the moral look of it, one has only to ask any decently honourable man, whether, under like circumstances, he would try to get rid of his responsibility by such a plea.
Hume's Inquiry appeared in 1748. He does not refer to Anthony Collins' essay on Liberty, published thirty-three years before, in which the same question is treated to the same effect, with singular force and lucidity. It may be said, perhaps, that it is not wonderful that the two freethinkers should follow the same line of reasoning; but no such theory will account for the fact that in 1754, the famous Calvinistic divine, Jonathan Edwards, President of the College of New Jersey, produced, in the interests of the straitest orthodoxy, a demonstration of the necessarian thesis, which has never been equalled in power, and certainly has never been refuted.
In the ninth section of the fourth part of Edwards' Inquiry, he has to deal with the Arminian objection to the Calvinistic doctrine that "it makes God the author of sin"; and it is curious to watch the struggle between the theological controversialist, striving to ward off an admission which he knows will be employed to damage his side, and the acute logician, conscious that, in some shape or other, the admission must be made. Beginning with a tu quoque, that the Arminian doctrine involves consequences as bad as the Calvinistic view, he proceeds to object to the term "author of sin," though he ends by admitting that, in a certain sense, it is applicable; he proves from Scripture, that God is the disposer and orderer of sin; and then, by an elaborate false analogy with the darkness resulting from the absence of the sun, endeavours to suggest that he is only the author of it in a negative sense; and, finally, he takes refuge in the conclusion that, though God is the orderer and disposer of those deeds which, considered in relation to their agents, are morally evil, yet, inasmuch as His purpose has all along been infinitely good, they are not evil relatively to him.
And this, of course, may be perfectly true; but if true, it is inconsistent with the attribute of omnipotence. It is conceivable that there should be no evil in the world; that which is conceivable is certainly possible; if it were possible for evil to be non-existent, the maker of the world, who, though foreknowing the existence of evil in that world, did not prevent it, either did not really desire it should not exist, or could not prevent its existence. It might be well for those who inveigh against the logical consequences of necessarianism to bethink them of the logical consequences of theism; which are not only the same, when the attribute of Omniscience is ascribed to the Deity, but which bring out, from the existence of moral evil, a hopeless conflict between the attributes of Infinite Benevolence and Infinite Power, which, with no less assurance, are affirmed to appertain to the Divine Being.
