It is equally idle to speak of pain as a form of discipline. Professor Sorley says that if the pain in the world can be turned to the increase of goodness, then its existence offers no insuperable objection to "the ethical view of reality." So Dr. Martineau says that suffering is "the moral discipline" through which our nature arrives at its "true elevation." It is needless to multiply quotations; such statements are the commonplaces of theistic controversy, and almost any book that one cares to pick up will supply further illustrations, if they be required. None can reject them, because no theist can afford to candidly admit that the world we know offers no justification for his belief. The belief in the goodness of God, as Canon Green says, is a belief that is "absolutely fundamental to all religion," and if the facts as we see them do not support the belief, some apology must be found that will marry the theory to the fact.
Nevertheless, the belief in the disciplinary power of pain or suffering is, if not quite illusory, so nearly so that it is useless for the purpose for which it is brought forward. In the first place, it does not require very profound study to see that whatever are the lessons taught by suffering they are seldom proportionate to the conduct which cause them, nor do those who suffer reap the alleged disciplinary benefit of their suffering. Let us take a common case. A mother goes out and leaves a child near an unguarded fire. The mother returns to find the child burned to death. Where is the discipline here? Certainly the child cannot have gained any. But there is, of course, the mother. The mother has learned such a lesson that she will never forget it, and will never again commit the same blunder. There we have it. A child is allowed to die by a hideously cruel death in order that a mother may learn a lesson in carefulness. It is good to learn from other sources that God's ways are not our ways. A man who tried to imitate them, and who burned one of his children in order to teach its mother how to look after the rest, would soon find himself in the criminal court, or in an asylum. But what would be insanity or criminal cruelty in the case of man, becomes, in the alembic of religious apologetic, goodness and wisdom in God.
The theory that it is the function of pain to elevate and to discipline is simply not true. One has only to look to see that in countless cases the effect of pain is disaster. The world's best work is not born of pain but of pleasure. There is no pain and no suffering, there is hardly even toil, in the work of a genius. In all the higher walks of music, of art, of literature, the work is perfect in proportion as the worker finds himself in agreeable and pleasant surroundings. And what is true of the higher aspect of art is true also of life in general. Life may be lived in spite of pain, as good work may be done in spite of discouraging circumstances, but one might as well talk of a plant flourishing because of poor soil, or sharp frosts, as to speak of life becoming better because of pain.
The normal function of pain is to depress, that of pleasure is to heighten. As Spencer said, every pain lowers the tide of life; every pleasure raises the tide of life. It is one of the commonest of sights to see those suffering from illness becoming more self-centred, less careful of others, and to see the disintegrating consequences of disease on character. Here and there one may find a character that has had its rough edges smoothed down by suffering, but for every case of that kind one may find a score of an opposite order. It is not the underfed, badly clothed, neglected child that is likely to make the best citizen, but the one that has the best chance of developing itself in healthy surroundings. And it is a curious commentary, if it were true, to argue that a good and wise God so arranged things that pain and suffering, even undeserved suffering, should be the main way for the development of character.
A strange but not uncommon argument is used by Canon Green in dealing with the suffering incidental to the various disasters that overtake mankind from time to time. Suffering, he says, has a certain element of martyrdom about it. Even evils due to human greed and carelessness bring some benefit in their train. Thus, apropos of the Titanic disaster:—
Every such disaster tends to produce some improvement for future generations. Shipowners are forced to supply more boats, wireless instalment is required on all ships; the idle rich are led to think less of saving useless time and more of saving lives, their own and those of men in the stokeholds. In a sense those who perish may be said to be unwilling martyrs who by their deaths purchase some advantage for others. It will be said that it is a great price to pay for a small advantage, and one which might have been cheaply gained in some other ways. That is so. But so too the ways of nature are cruel. So many seeds must be sown, so many young animals or birds or fishes born, so many must be trampled out of existence, that only the best may survive. (Problem of Evil; pp. 163-4).
That certainly puts all the owners of slum property, all the grasping shipowners, all those who batten and fatten on other people's welfare in a most favourable light. We have been thinking them almost criminals when they were in reality public benefactors. They lead to many improvements, and even though the improvements come too late to benefit those who suffer from the evils, yet they do come—sometimes. Certainly it might give some comfort if the sufferers knew what it was they were being sacrificed for, and that others would be benefited by their death. But they do not, and we are therefore bound to conclude that whatever satisfaction is felt is by those who survive. When a Titanic sinks it must be the people on shore who see the element of goodness in it since it makes travelling easier for them. And the kindness developed in one who can excuse the brutalities of nature because it brings some benefit to himself is of a rather startling nature.
The fundamental fault in all reasoning of this order lies in the assumption that pain ceases to be pain if it can be shown to bring good to some one. But that it not so. Pleasure and pain are not quantitative things, increments of which can be carried on from generation to generation and a balance struck at the end, much as one strikes a balance between the profits and losses of a year's trading. All suffering and all enjoyment are of necessity personal. Suffering is not increased by extending it over a million instances. There was not more pain because a larger number happened to be be killed in the European war than are killed in a borderland skirmish. There were a larger number of people involved in the one case than in the other, but that is all. Multiplying the number of cases makes a greater appeal to a sluggish imagination, but it adds nothing substantial to the fact. Feeling, whether it be pleasant or painful, is a matter of individual experience, and that being so it is not the number of people who suffer through no fault of their own, and, so far as one can see, without any benefit proportionate to the suffering experienced, but the fact of there being this suffering at all. That is the point the theist must face; it is the one point he systematically avoids.
Another form of the same argument meets us in the familiar plea that bodily pain "sounds the alarm bell of disease in time for its removal." In some sense it may be admitted that a painful feeling, in certain circumstances, does act as a warning that persistence will lead to disaster. But it is not universally true in the sense and in the degree that is needed to justify the argument, and it is a "warning" out of all proportion to the danger faced. In the first place, pain cannot be a warning against disease, it can only be an indication of its presence. It does not warn us against the dangers of a contemplated course of conduct, nor can it tell us what conduct has led to the pain experienced. And in the case of contagious diseases, what amount of warning is there given? In some case the victim is stricken and is dead in so short a time as not to know with what it is he has been afflicted, and certainly without any chance of being warned. What warning is there in the case of a violent poison? Or what relation is there between pains felt and dangers run? The most dangerous diseases may have painless beginnings, and be well rooted in the system before the victim is driven by discomfort to seek medical advice. On the other hand, a corn or a toothache, neither of them very deadly ailments, create pain out of all proportion to their gravity. And if we take the case of excessive cold we have here an instance where instead of pain acting as a warning, the danger just acts as an anæsthetic. The victim is oppressed by drowsiness, sinks into insensibility, finally death. Here it is not the approach of death that is painful, but the return to life, the pain of restoring circulation being very severe indeed.
