Moral insanity thus understood, as a derangement of the passions lessening a man's full mastery of himself, but not destroying it altogether, assumes various forms. There are kleptomania, or an abnormal impulse to steal; pyromania, an impulse to set things on fire; dipsomania, or an abnormal fondness for intoxicants; nymphomania, or the tyranny of lustful passions; homicidal mania, or a craving to commit murder; etc. In all these the nature of the disease is the same, it would appear. The imagination seizes the pleasure vividly, yet, it is claimed, without delusion: and the passion, owing to organic disorder, is abnormally excitable. The organic derangement is supposed to be in the brain. For the human brain, a masterpiece of the Creator's wisdom, is now generally believed to consist of various portions which are the organs of the passions, of motive power and the phantasms, erroneously called ideation. Hence it is easy to understand how it may happen that one portion is diseased while the other parts are in a normal condition. And on the other hand it thus appears very probable also that a brain partially diseased is liable to be soon affected in the other parts as well. Hence we may suspect that moral insanity is likely to bring on delusional insanity, and _vice versa_. In fact, I find that a medical expert of note, who had for many years taught that moral insanity was quite a distinct disease and separate from mental insanity, has in his old age changed his mind to some extent on this subject. "Of late years," says Dr. Bauduy, of St. Louis, in his learned work on "Diseases of the Nervous System," "I have believed, notwithstanding the doctrine of Pritchard, that a careful study of moral insanity will enable us to detect some evidence, although, it must be confessed, often very feeble, of mental weakening. Even the classic cases of Pritchard," he adds, "who first defined the so-called moral insanity, when carefully examined, will confirm this statement" (p. 227). Usually, as the same Dr. Bauduy explains, those who are morally insane are at least on the high road to mental insanity (p. 228). Moral insanity is known to exist when there is a sudden change of character which can have no other source than bodily disease; as when a most honest man becomes of a sudden an habitual thief, a decent man openly profane, a miser becomes extravagantly liberal, an affectionate father a very tyrant to his children, without any traceable causes for such transformation. The disease is made more manifest if such a sudden change is preceded by certain physical conditions, such as epilepsy, hereditary taint, suicidal attempts, "the insane temperament," as it is called, and other influences which are to be taken into consideration.

If ever you be summoned, gentlemen, to testify or pronounce on a person's insane condition, let me give you one piece of advice which may spare you much unpleasantness: be unusually cautious of what you say. If you appear as an expert or a witness, and you make a mistake unfavorable to the patient, he will be your enemy for life; even he may at times recover damages for libel. If he is really crazy, he may be all the more dangerous. Do your duty, of course, as an honest man must always do; but do it very prudently.

Dr. Bauduy is very emphatic on the assertion that moral insanity is not moral depravity. He is perfectly right; yet we must not forget that moral depravity is often screened before the courts by the plea of insanity. When a man of bad antecedents commits a crime, and is known to have been sane just before and after the deed, he ought not to be excused on the plea that he may have been insane at the moment when he committed the act; there is no reason for such a plea. And with the victims of kleptomania, dipsomania, and other moral manias, it is well known that a sound whipping will often stop the nuisance. The rod for the juvenile offender, and the whipping-post for adults, would cure many a moral leper and be a strong protection for society at large, especially if applied before bad habits freely indulged have demoralized the person beyond the usual limits. All of us have our passions; they are an essential part of our nature and even an indispensable part. But they should be controlled by reason and will, whereas they are often indulged with guilty weakness. They are much strengthened by indulgence, especially in those predisposed to certain vices by hereditary transmission. No doubt some children have worse passions to contend against than others. It is still worse if, at the same time, their surroundings are unfavorable to virtue; and this is a constant source of increase to the criminal classes.

Wise statesmen will study the ways in which temptations to vice may be diminished; but it is mistaken mercy and dangerous to the community to spare the guilty when once they have committed criminal acts. If ever the principle were admitted in our courts of justice that the possible existence of mental insanity ought to protect a culprit from punishment, crime would soon increase tenfold both in the sane and in the insane. Both classes must be kept impressed with the conviction that the law rules supreme and will not tolerate the destruction of public safety. Your profession, gentlemen, in this matter as in many others, by its sound views on Jurisprudence and Ethics, is one of the strongest bulwarks of the common good.

LECTURE IX.

HYPNOTISM AND THE BORDER-LAND OF SCIENCE.

In this last lecture of our course I propose to make a brief excursion with you into the border-land of science, a region chiefly occupied by imposture and superstition. To show there is such a territory, we have only to name a few of its inhabitants, such as mesmerism, animal magnetism, odylism, hypnotism, mind-reading, faith-cures, clairvoyance, spiritism, including table-rapping, spirit-rapping, most of which have been used in connection with medicine. I do not maintain that all of these are mere vagaries, empty shadows, without the least reality, mere ghosts and hobgoblins, mere phantoms of the heat-oppressed brain, or cunning devices of impostors to deceive a gullible crowd of the ignorant public. Yet most of these are such beyond a doubt, and as such are totally unworthy of our attention.

Medicine is a science; it deals with undoubted facts and certain principles, and with theories in so far as they are supported by well-ascertained realities. The border-land of which I speak presents to our investigation few certain facts. It is chiefly the domain of imposture. Charlatans and showmen and medical quacks call things facts that are not facts. Among all the inhabitants of the shadowy region that I have enumerated, there is only one considered to-day by the science of medicine as worthy of its attention. It is hypnotism. As its first origin is connected with the history of mesmerism, and the latter, though itself a phantom, has been used as the chief patron of all other phantoms, I will premise a few words about mesmerism itself.

I. Mesmer was born about 1733, studied in Vienna and there became a doctor of medicine in 1766. Soon after, he began to speculate upon the curative powers of the magnet, and claimed to have discovered the existence of a force in man similar to magnetism and the source of strong influence on the human body.

In 1775 he published an account of the medical powers of this animal magnetism, which from his name was afterward called _mesmerism_. Paris was then the centre of attraction for scientific discoverers and pretenders. Thither Mesmer betook himself and there he soon created a lively sensation by the exhibition of mesmeric trances, some of which were accompanied by clairvoyance--that is, the power of seeing objects concealed from the eyes. He was also supposed to work some inexplicable cures.

The secret of his art he could not be induced to reveal even for the sum of 340,000 livres, which was offered him in compensation. People began to doubt whether he had a real secret, or whether he was a rank impostor. A royal commission was appointed to examine into the matter. Our Benjamin Franklin, then in Paris, was one of the commissioners. Their report was unfavorable. They found no proof of the existence of a fluid such as animal magnetism, and thought that all that was not imposture could be accounted for by the power of imagination. In a secret report they pointed out very strongly the dangers likely to arise from this unhealthy stimulus to the imagination. Their verdict does honor to their learning and their common-sense. Mesmer left Paris, and he died in obscurity in 1815.

But his pretended discovery did not die with him. It was a mine of resources to charlatans and impostors generally. There were strange effects produced, and at the sight of the inexplicable men lose their wits. The gullible public wondered, restless minds experimented, and many pondered thoughtfully on facts, most of which were not facts at all. But after eliminating all the elements of imposture and exaggeration there seemed to remain a residue of phenomena that were strange and unaccountable.

II. THEORY OF HYPNOTISM.

About 1840 the vaunted claims of the many clairvoyants were exposed before the French Academy of Medicine, which passed a resolution rejecting mesmerism altogether as unworthy of notice on the part of scientific men. The theory of a mesmeric fluid, until then the only one advanced, had evidently to be abandoned. Science with all its tests could find no such cause of the results produced. But in 1842 an English physician, Dr. James Braid, hit upon a more plausible theory. He conjectured that the actions of the mesmeric subject could be explained without a fluid by the suggestion of phantasms to him on the part of the mesmerizer. Dr. Carpenter, then a great authority, defended his theory; but the medical branch of the British Association disdained to consider the matter. Dr. Braid thought the mesmeric trance was only a state of somnambulism artificially brought about, and he coined the word _hypnotism_ to indicate the artificial sleep. Other attempts to promote the cause of hypnotism were made in the United States and other lands, but no very definite or scientific results were reached until 1878, when the celebrated Prof. Charcot and others made its nature and possibilities the subject of a thorough study and abundant experimentation at the Paris hospital of La Salpétrière and in other places. At present it is admitted by distinguished medical scientists that hypnotism is a reality, capable of being utilized for important purposes. Many effects have been demonstrated to be produced by it as real as any ordinary phenomena of nature. But on the explanation of their causes there hangs still a cloud of obscurity.

The Paris School of Doctors attribute the effects to physical causes, chief among which are diseases of the nerves. Those of Nancy trace the phenomena to a psychical source, namely, to suggestion--that is, action on the subject through his imagination excited by words, signs, or in any other manner. This appears to be, in the main, the theory of Dr. Braid vindicated by modern science. Probably enough, both schools are right in their way, the suggestions not taking effect except where nervous affections have prepared the way. The beneficial results claimed for hypnotism by the scientific men who have made its study a specialty are chiefly as follows:

III. BENEFITS OF HYPNOTISM.

1. It acts as a temporary sedative, quieting the excited nerves of the patient. It was thus employed, for instance, on an old woman who was near her death, and who had not been able to make necessary preparations for that important event, being beside herself with nervous agitation. She obtained by this means a calm condition for some seven or eight hours. Hypnotism was for her like the visit of a good angel from heaven.

2. It is used as an anæsthetic in place of chloroform, which in many cases cannot be applied without great danger to health, or even life. Thus perfect insensibility may be procured and long continued, allowing sometimes of the performance of protracted surgical operations that would otherwise be almost impossible.

3. At other times it is employed as a mere pain-killer without depriving the patient of consciousness, so that the hurt is felt indeed, but not attended with keen suffering.

4. It is claimed that the skilful application of hypnotism can at times not only alleviate the pain of an injury, but even cure nervous affections more or less permanently, removing, for instance, the defect of stammering.

5. There are not wanting cases in which even moral improvements are claimed to be produced, at least in the removing of bad habits, such as drunkenness. If hypnotism can cure intoxication permanently, or even for a season, it deserves to be encouraged. Yet even then it must be used with great caution, for there may be very evil consequences resulting from its use. To realize fully the dangers and the evils attendant upon hypnotism you must understand the three stages through which the patient is made to pass--those of lethargy, catalepsy, and somnambulism.

IV. DANGEROUS TREATMENT.

Each of these is a disease in itself, and thus it is seen at once that a treatment which employs diseases as its means of cure must be of a dangerous kind. After the patient has been hypnotized by any of the various processes--the chief are mesmeric passes of the hypnotizer's hands, his eyes fixed into the eyes of his subject, or the latter's on an object so held as to strain his eyes--the first stage of hypnotism is obtained, that of lethargy. In the lethargic state, the subject appears to be sunk in a deep sleep; his body is perfectly helpless; the limbs hang down slackly, and when raised fall heavily into the same position. In this condition all the striated or voluntary muscles react on mechanical excitement. Without an accurate knowledge of anatomy, much harm may be done by the experiment.

The second stage is that of catalepsy, certainly not a healthy condition to be in. Its grand feature is a plastic immobility by which the subject maintains all the attitudes given to his body and limbs, but with this peculiarity, that the limbs and features act in unison. Join the hands of the patient as if in devout prayer, and his countenance assumes a devout expression; clench his fist, and anger is depicted in his features.

The third stage is that of somnambulism. The skin is now insensible to pain, but excessive keenness is manifested in the sight, hearing, smell, and muscular sense. Here the impostor can play off his pretended clairvoyance or second sight; for the subject will discover objects hidden from sight by the sense of smell and other senses affected with abnormal power. The somnambulist will now exhibit the utmost sensibility to suggestions made to him by the hypnotizer, so that he seems to be almost entirely controlled by the influence of the latter's will. This is what chiefly favored the early theory that a mesmeric fluid emanated from the mesmerizer by means of which he could act in his subject as he pleased. The experiment by suggestions seems to succeed best with hysterical patients, which fact confirms the morbid character of the hypnotic trance.

V. FIELD FOR A SCIENTIST.

If any distinguished scientist or Doctor who can afford it wishes to make a special study of hypnotism, which is still so imperfectly understood, he may render a valuable service to humanity, and in particular to the science of medicine. But if any ordinary physician asked my advice about devoting attention to this pursuit. I would emphatically tell him, "Leave it alone: you are not likely to derive real benefit from it, and you are very likely to inspire your clients with distrust of you when they see you deal with matters which have deserved a bad name on account of the charlatanism and the superstitious abuses usually connected with them." This is not my opinion alone, but also that of distinguished writers on the subject.

VI. OBJECTIONS TO HYPNOTISM.

When there is question of hypnotic séances or exhibitions such as are designed to feed the morbid cravings of the public for what is mysterious and sensational, I would call special attention to the following objections against such practices.

1. Medical authorities maintain that it requires at least as much knowledge of therapeutics to use hypnotism safely as it does for the general practice of medicine, and requires of a physician who engages in it a more thorough mastery of his profession than many other branches of the healing art, and therefore that it is as objectionable to allow non-professionals to deal with hypnotism as it would be to allow medical practice promiscuously to all persons without a Doctor's diploma. In fact, in Russia, Prussia, and Denmark none but licensed physicians can lawfully practise hypnotism. Aside from a variety of accidents which may result to the subject hypnotized from the ignorance of physiology in the hypnotizer, there is this general injury sustained, that even strong subjects frequently experimented upon contract a disposition to be readily thrown into any of the three morbid states of the mesmeric trance. All these states are real diseases and are allied to hysteria, epilepsy, and a whole family of nervous troubles, any one of which is sufficient to make a patient very miserable for life, and even to lead him to an early grave.

2. The moralist has still stronger objections against the use of hypnotism, except when it is used as a means to most important results. He maintains that one of the greatest evils that can befall a man is the weakening of his will-power; this leaves him a victim to the cravings of his lower appetites. Now the frequent surrender of one's will to the control of another is said (very reasonably, it would seem) to bring on a weakening of the will or self-control. We see this exemplified in the habitual drunkard. He loses will-power to such an extent that he can scarcely keep his most solemn promises or withstand the slightest temptations. There is a very serious question asked by the moralist upon another resemblance of an hypnotic subject to a drunkard. He asks whether any man has a right for the amusement perhaps of the curious lookers-on to forfeit for awhile his manhood, or the highest privilege of his manhood--his powers of intellect and free-will. He admits that we do so daily in our sleep. But then he argues that sleep is a necessity of our nature directly intended by the Creator, a normal part of human life. Besides it is a necessary means for the renewal of our strength, and on the plea of necessity the moralist may admit the use of hypnotism when it is needed for the cure of bodily diseases. But for the mere amusement of spectators he maintains that it is wrong for a man thus to resign his human dignity, as it would be wrong for him to get drunk for the amusement of lookers-on. Still, in this latter case the evil would be greater, for in drunkenness there is contained a lower degradation, inasmuch as the baser passions are then left without all control, and are apt to become exceedingly vile in their licentious condition. The hypnotic subject has at least the mind and will of the hypnotizer to direct him. Here, however, appears the need of another caution, namely, that the hypnotizer should be known to be a virtuous man; else the evil that he can do to his subject, as is readily seen, may be even worse than that resulting from a fit of drunkenness. And as men who occupy even respectable positions may yet be vile at heart, it is very desirable for prudence' sake to have no one hypnotized in private without the presence of a parent, close relative, or some other party, who will see to it that nothing improper be suggested during the trance. For the scenes gone through during the hypnotic state, though not remembered by the subject upon his return to consciousness, are apt to recur to him afterwards like a dream, showing that they have left traces behind them.

3. Legal writers and lawyers have serious charges against hypnotism. This practice, they maintain, if publicly exhibited to old and young, begets dangerous cravings for sensational experiments. Turning away men's attention from the sober realities and duties of social life, it prompts them to pursue the unnatural and abnormal. It was this craving that in less enlightened ages led men to the superstitious practice of astrology and witchcraft. At present it leads to such vagaries and unchristian and often immoral practices as are connected with spiritism, faith-cures, mind-reading, and similar foolish or criminal or at least dangerous experimentations which dive into the dark recesses found in the border-land of the preternatural. The atmosphere of that region is morally unhealthy and should be barred off by the guardians of public morals.

The most common objection of legal writers is directed against the various crimes to which hypnotism is apt to lead men of criminal propensities. They point to the statements of Dr. Luys, a respectable authority on hypnotism, who says: "A patient under the influence of hypnotism can be made to swallow poison, to inhale noxious gases. He can be led to make a manual gift of property, even to sign a promissory note or bill, or any kind of contract." Indeed, how can notaries or witnesses suspect any fraud when even the Doctor needs all his experience and all his skill to avoid falling into error? In criminal matters a man under suggestion can bring false accusations and earnestly maintain that he has taken part in some horrible crime.

VII. FURTHER EXPLANATION OF HYPNOTISM.

After considering the objections to the use, or rather abuse, of hypnotism, I may add some further explanation of hypnotism itself--of its nature so far as it is known to science. Science has ascertained the reality of the phenomena and facts--not single facts only, scattered here and there, but groups of facts uniformly obedient to certain laws of nature. It has not yet discovered the exact cause or causes of all these phenomena, but it gives plausible explanations of them, both in the physical theory of the Paris School and in the psychical theory of the Nancy School of Physicians. Science has discarded the original theory of a mesmeric fluid as the cause of these phenomena, just as it has discarded the formerly supposed fluids of electricity and magnetism. Of electricity the "Century Dictionary" says: "A name denoting the cause of an important class of phenomena of attraction and repulsion, chemical decomposition, and so on, or, collectively, these phenomena themselves." The true nature of electricity is as yet not all understood, but it is not, as it was formerly supposed to be, of the nature of a fluid. Similarly we may define hypnotism as the collection of peculiar phenomena of a trance or sleep artificially induced, or the induced trance or sleep itself.

The true cause of these phenomena is not yet understood, but there is no apparent reason for attributing them to a special fluid; they seem to be peculiar ways of acting, belonging to man's physical powers when his nerves are in an abnormal condition. By laying down these definite statements we gain the advantage that we isolate hypnotism from the frauds and empty shades, from the ghosts and hobgoblins with which it used to be associated in the border-region which we have undertaken to explore. Science deals with well-ascertained facts. Now of mesmerism, animal magnetism, and its kindred, odylism, we have seen that we have no reliable facts. We have done with those unsubstantial shades. But of hypnotism we have well-known facts, and we have shown it to be placed on a scientific basis.

VIII. SCIENCE DREADS ERROR.
