They cannot see the exception is different from the rule—even when it is misrule, even when it is an unruly rule. The sound sense in the old Lunacy Law was this: that you cannot deny that a man is a citizen until you are practically prepared to deny that he is a man. Men, and only men, can be the judges of whether he is a man. But any private club of prigs can be judges of whether he ought to be a citizen. When once we step down from that tall and splintered peak of pure insanity we step on to a tableland where one man is not so widely different from another. Outside the exception, what we find is the average. And the practical, legal shape of the quarrel is this: that unless the normal men have the right to expel the abnormal, what particular sort of abnormal men have the right to expel the normal men? If sanity is not good enough, what is there that is saner than sanity?
Without any grip of the notion of a rule and an exception, the general idea of judging people's heredity breaks down and is useless. For this reason: that if everything is the result of a doubtful heredity, the judgment itself is the result of a doubtful heredity also. Let it judge not that it be not judged. Eugenists, strange to say, have fathers and mothers like other people; and our opinion about their fathers and mothers is worth exactly as much as their opinions about ours. None of the parents were lunatics, and the rest is mere likes and dislikes. Suppose Dr. Saleeby had gone up to Byron and said, "My lord, I perceive you have a club-foot and inordinate passions: such are the hereditary results of a profligate soldier marrying a hot-tempered woman." The poet might logically reply (with characteristic lucidity and impropriety), "Sir, I perceive you have a confused mind and an unphilosophic theory about other people's love affairs. Such are the hereditary delusions bred by a Syrian doctor marrying a Quaker lady from York." Suppose Dr. Karl Pearson had said to Shelley, "From what I see of your temperament, you are running great risks in forming a connection with the daughter of a fanatic and eccentric like Godwin." Shelley would be employing the strict rationalism of the older and stronger free thinkers, if he answered, "From what I observe of your mind, you are rushing on destruction in marrying the great-niece of an old corpse of a courtier and dilettante like Samuel Rogers." It is only opinion for opinion. Nobody can pretend that either Mary Godwin or Samuel Rogers was mad; and the general view a man may hold about the healthiness of inheriting their blood or type is simply the same sort of general view by which men do marry for love or liking. There is no reason to suppose that Dr. Karl Pearson is any better judge of a bridegroom than the bridegroom is of a bride.
An objection may be anticipated here, but it is very easily answered. It may be said that we do, in fact, call in medical specialists to settle whether a man is mad; and that these specialists go by technical and even secret tests that cannot be known to the mass of men. It is obvious that this is true; it is equally obvious that it does not affect our argument. When we ask the doctor whether our grandfather is going mad, we still mean mad by our own common human definition. We mean, is he going to be a certain sort of person whom all men recognise when once he exists. That certain specialists can detect the approach of him, before he exists, does not alter the fact that it is of the practical and popular madman that we are talking, and of him alone. The doctor merely sees a certain fact potentially in the future, while we, with less information, can only see it in the present; but his fact is our fact and everybody's fact, or we should not bother about it at all. Here is no question of the doctor bringing an entirely new sort of person under coercion, as in the Feeble-Minded Bill. The doctor can say, "Tobacco is death to you," because the dislike of death can be taken for granted, being a highly democratic institution; and it is the same with the dislike of the indubitable exception called madness. The doctor can say, "Jones has that twitch in the nerves, and he may burn down the house." But it is not the medical detail we fear, but the moral upshot. We should say, "Let him twitch, as long as he doesn't burn down the house." The doctor may say, "He has that look in the eyes, and he may take the hatchet and brain you all." But we do not object to the look in the eyes as such; we object to consequences which, once come, we should all call insane if there were no doctors in the world. We should say, "Let him look how he likes; as long as he does not look for the hatchet."
Now, that specialists are valuable for this particular and practical purpose, of predicting the approach of enormous and admitted human calamities, nobody but a fool would deny. But that does not bring us one inch nearer to allowing them the right to define what is a calamity; or to call things calamities which common sense does not call calamities. We call in the doctor to save us from death; and, death being admittedly an evil, he has the right to administer the queerest and most recondite pill which he may think is a cure for all such menaces of death. He has not the right to administer death, as the cure for all human ills. And as he has no moral authority to enforce a new conception of happiness, so he has no moral authority to enforce a new conception of sanity. He may know I am going mad; for madness is an isolated thing like leprosy; and I know nothing about leprosy. But if he merely thinks my mind is weak, I may happen to think the same of his. I often do.
In short, unless pilots are to be permitted to ram ships on to the rocks and then say that heaven is the only true harbour; unless judges are to be allowed to let murderers loose, and explain afterwards that the murder had done good on the whole; unless soldiers are to be allowed to lose battles and then point out that true glory is to be found in the valley of humiliation; unless cashiers are to rob a bank in order to give it an advertisement; or dentists to torture people to give them a contrast to their comforts; unless we are prepared to let loose all these private fancies against the public and accepted meaning of life or safety or prosperity or pleasure—then it is as plain as Punch's nose that no scientific man must be allowed to meddle with the public definition of madness. We call him in to tell us where it is or when it is. We could not do so, if we had not ourselves settled what it is.
As I wish to confine myself in this chapter to the primary point of the plain existence of sanity and insanity, I will not be led along any of the attractive paths that open here. I shall endeavour to deal with them in the next chapter. Here I confine myself to a sort of summary. Suppose a man's throat has been cut, quite swiftly and suddenly, with a table knife, at a small table where we sit. The whole of civil law rests on the supposition that we are witnesses; that we saw it; and if we do not know about it, who does? Now suppose all the witnesses fall into a quarrel about degrees of eyesight. Suppose one says he had brought his reading-glasses instead of his usual glasses; and therefore did not see the man fall across the table and cover it with blood. Suppose another says he could not be certain it was blood, because a slight colour-blindness was hereditary in his family. Suppose a third says he cannot swear to the uplifted knife, because his oculist tells him he is astigmatic, and vertical lines do not affect him as do horizontal lines. Suppose another says that dots have often danced before his eyes in very fantastic combinations, many of which were very like one gentleman cutting another gentleman's throat at dinner. All these things refer to real experiences. There is such a thing as myopia; there is such a thing as colour-blindness; there is such a thing as astigmatism; there is such a thing as shifting shapes swimming before the eyes. But what should we think of a whole dinner party that could give nothing except these highly scientific explanations when found in company with a corpse? I imagine there are only two things we could think: either that they were all drunk, or they were all murderers.
And yet there is an exception. If there were one man at table who was admittedly blind, should we not give him the benefit of the doubt? Should we not honestly feel that he was the exception that proved the rule? The very fact that he could not have seen would remind us that the other men must have seen. The very fact that he had no eyes must remind us of eyes. A man can be blind; a man can be dead; a man can be mad. But the comparison is necessarily weak, after all. For it is the essence of madness to be unlike anything else in the world: which is perhaps why so many men wiser than we have traced it to another.
Lastly, the literal maniac is different from all other persons in dispute in this vital respect: that he is the only person whom we can, with a final lucidity, declare that we do not want. He is almost always miserable himself, and he always makes others miserable. But this is not so with the mere invalid. The Eugenists would probably answer all my examples by taking the case of marrying into a family with consumption (or some such disease which they are fairly sure is hereditary) and asking whether such cases at least are not clear cases for a Eugenic intervention. Permit me to point out to them that they once more make a confusion of thought. The sickness or soundness of a consumptive may
