But if penal laws thus express the wide variability of human morality, they also contribute to make actions moral or immoral according to the penalties by which they enforce or prevent them. For not only does whatever is immoral tend to become penal, but anything can be made immoral by being first made penal; and hence indifferent actions often remain immoral long after they have ceased to be actually punishable. Thus the Jews made Sabbath-breaking equally immoral with homicide or adultery, by affixing to each of them the same capital penalty; and the former offence, though it no longer forms part of any criminal code, has still as much moral force against it as many an offence directly punishable by the law.

But perhaps the best illustrations of the tendency of actions to retain the infamy, attached to them by a past condition of fanatical punishments, are the cases of suicide and child-killing. Could a Greek of the classical period, or a cultivated historian like Plutarch reappear on earth, nothing would strike him more vividly than the modern conception or recent treatment of these crimes. According to Plutarch, Lycurgus, the great Spartan lawgiver, met his death by voluntary starvation, from the persuasion that even the deaths of lawgivers should be of use to mankind, and serve them with an example of virtue and greatness; and Seneca held that it was the part of a wise man not to live as long as he could but as long as he ought. With what astonishment, then, would not Plutarch or Seneca read of recent European punishments for suicide—of Lady Hales losing the estate she was jointly possessed of with her husband, the Judge, because he drowned himself; of the stake and the cross-roads; of the English law which still regards suicide as murder, and condemns one of two men who in a mutual attempt at self-destruction survives the other to the punishment of the ordinary murderer! Is it possible, he would ask, that an action which was once regarded as among the noblest a man could perform, has really come to be looked upon with any other feeling than one of pity or a sad respect?

The case of infanticide suggests similar thoughts. When we remember that both Plato and Aristotle commended as a valuable social custom that which we treat as a crime; when we recall the fact that the life of a Spartan infant depended on a committee of elders, who decided whether it should live or perish, we shall better appreciate the distance we have travelled, or, as some would say, the progress we have made, if we take up some English daily paper and read of some high-minded English judge sentencing, at least formally, some wretched woman to death, because, in order to save her child from starvation or herself from shame, she has released it from existence. Yet the feeling, of which such a sentence is the expression, is often extolled as one of the highest triumphs of civilisation; and the laws, as if there were no difference between adult and infant life, glory in protecting the weakness of a child by their merciless disregard for the weakness of its mother.

But at least, it will be thought, we have by this time arrived at some principles about punishment which correspond with the eternal truths of equity. Is not Equality, for instance, one of the primary essentials of punishment? Does it not stand as a penal axiom with almost the sanction of a moral law that all men should suffer equally for equal crimes? Yet, if by equality be meant the same punishment, the same kind of labour, the same term of servitude, the same pecuniary fine—and this is the only thing it can mean—what more obvious than that the same punishment for rich and poor, for young and old, for strong and weak, for men and women, for educated and uneducated, will bring to the constitution of a penal code the utmost inequality the imagination can conceive? Beccaria insists that the law can do no more than assign the same extrinsic punishment to the same crime; that is, the same punishment, regardless of all other external considerations; and he calls for the infliction of the same punishment on the nobleman as on the commoner. Let it be so; but the same punishment is no longer an equal one; and hence from this very demand for equality springs the demand for its very opposite, for what Bentham calls the equability of punishment; that is, consideration for the different circumstances of individual criminals. So that the same nominal punishment not being the same real one, equality of punishment appears to be a chimera, and the law, which punishes, say, a distinguished officer less severely than it punishes a costermonger for the same crime, errs perhaps really less from actual equality than if it condemned both to precisely the same punishment.

Again, Proportion between crime and punishment seems to be another natural demand of equity. Yet it is evident that it is only approximately possible, and will vary in every age and country according to the prevalent notions of morality. Is imprisonment for a year, or imprisonment for life, or for how long, a fair and proportionate punishment for perjury? Who shall decide? Shall we submit it to the opinion of the judges? But has not Romilly left on record the story of the two men tried by two different judges for stealing some chickens, who were sentenced respectively one to imprisonment for two months, and the other to transportation? Shall we then give up all attempt at proportion and apply the same deterrent as equally efficacious against slight or grave offences? Draco, when asked why he made death the punishment for most offences that were possible, is said to have replied, ‘Small ones deserve it, and I can find no greater for the gravest.’ The same reasoning was for a long time that of our own law; and in Japan, where every wrong act was one of disobedience to the Emperor, and accordingly of equal value, the same penalty of death for gambling, theft, or murder, obviated all difficulties with regard to a proportion which is easier to imagine than it is to define.

Analogy between crime and punishment is another idea which, except in the case of death for death, has been relegated from the practice of most criminal laws. Yet the principle has in its favour the authority of Moses, the authority of the whole world and of all time, that punishment should, if possible, resemble the crime it punishes in kind; so that a man who blinds another should be blinded himself, he who disfigures another be disfigured himself. Thus in the old-world mythology, Theseus and Hercules inflict on the evil powers they conquer the same cruelties their victims were famous for; Termenus having his skull broken because with his own skull he broke the heads of others; and Busiris, who sacrificed others, being himself sacrificed in his turn. Both Montesquieu and Beccaria also advocate analogy in punishment, and so does Bentham to some degree; there being, indeed, few greater contrasts between the theories of the great English jurist and modern English practice than that the former should not have deprecated some suffering by burning as a penalty analogous to the crime of arson, and that he should have advised the transfixing of a forger’s hand or of a calumniator’s tongue by an iron instrument before the public gaze as good and efficient punishments for forgery and slander.

These are some of the difficulties of the subject, which teach us the necessity of constant open-mindedness with regard to all ideas or practices connected with criminal law. But, would we further examine our established notions, we should consider a statement from Hobbes which goes to the very root of the theory of punishment.

‘In revenges or punishments,’ says Hobbes, ‘men ought not to look at the greatness of the evil past, but the greatness of the good to follow, whereby we are forbidden to inflict punishment with any other design than for the correction of the offender and the admonition of others.’ And over and over again the same thing has been said, till it has come to be a commonplace in the philosophy of law, that the object of punishment is to reform and deter. As was once said by a great legal authority, ‘We do not hang you because you stole a horse, but that horses may not be stolen.’[42] Punishment by this theory is a means to an end, not an end in itself.

Yet, supposing it were proved to-morrow that punishment fails entirely of the ends imputed to it; that, for example, the greater number of crimes are committed by criminals who have been punished already; that for one chance of a man’s reformation during his punishment there are a hundred in favour of his deterioration; and that the deterrent influence of his punishment is altogether removed by his own descriptions of it; shall we suppose for a moment that society would cease to punish, on the ground that punishment attained none of its professed ends? Would it say to the horse-stealer, ‘Keep your horse, for nothing we can do to you can make you any better, nor deter others from trying to get horses in the same way?’

Or to take a stronger case. A deserter from the ranks escapes to his home, breaks into it at night, robs an infirm father of all the savings he has provided for his old age, and in a struggle for their possession so injures him that he dies. Must the law disclaim all indignation, all resentment, in the punishment it inflicts, and say to such a ruffian that it only deals hard with him in order to warn others by his example, and with the pious hope of making a good man of him in the future? If resentment is ever just, is it wrong to give it public expression? If it is natural and right in private life, why should it be a matter of shame in public life? If there is such a thing as just anger for a single man, does it become unjust when distributed among a million?
