Chapter 11

Let us take the case of another still greater and more famous man, Rousseau. It cannot reasonably be doubted that, at some moments in his life at all events, and perhaps during a considerable period, Rousseau was definitely insane. We are intimately acquainted with the details of the life and character of his relations and of his ancestry. We not only possess the full account he set forth at the beginning of his _Confessions_, but we know very much more than Rousseau knew. Geneva was paternal--paternal in the most severe sense--in scrutinising every unusual act of its children, and castigating every slightest deviation from the straight path. The whole life of the citizens of old Geneva may be read in Genevan archives, and not a scrap of information concerning the conduct of Rousseau's ancestors and relatives as set down in these archives but has been brought to the light of day. If there is any great man of genius whom the activities of these fanatical eugenists would have rendered impossible, it must surely have been Rousseau. Let us briefly examine his parentage. Rousseau's father was the outcome of a fine stock which for two generations had been losing something of its fine qualities, though without sinking anywhere near insanity, criminality, or pauperism. The Rousseaus still exercised their craft with success; they were on the whole esteemed; Jean-Jacques's father was generally liked, but he was somewhat unstable, romantic, with no strong sense of duty, hot-tempered, easily taking offence. The mother, from a modern standpoint, was an attractive, highly accomplished, and admirable woman. In her neighbours' eyes she was not quite Puritanical enough, high-spirited, independent, adventurous, fond of innocent gaiety, but a devoted wife when, at last, at the age of thirty, she married. More than once before marriage she was formally censured by the ecclesiastical authorities for her little insubordinations, and these may be seen to have a certain significance when we turn to her father; he was a thorough _mauvais sujet_, with an incorrigible love of pleasure, and constantly falling into well-deserved trouble for some escapade with the young women of Geneva. Thus on both sides there was a certain nervous instability, an uncontrollable wayward emotionality. But of actual insanity, of nervous disorder, of any decided abnormality or downright unfitness in either father or mother, not a sign. Isaac Rousseau and Susanne Bernard would have been passed by the most ferocious eugenist. It is again a case in which the chances of convergent heredity have produced a result which in its magnitude, in its heights and in its depths, none could foresee. It is one of the most famous and most accurately known examples of insane genius in history, and we see what amount of support it offers to the ponderous dictum concerning the insane heredity of genius.

Let us turn from insanity to grave nervous disease. Epilepsy at once comes before us, all the more significantly since it has been considered, more especially by Lombroso, to be the special disease through which genius peculiarly manifests itself. It is true that much importance here is attached to those minor forms of epilepsy which involve no gross and obvious convulsive fit. The existence of these minor attacks is, in the case of men of genius, usually difficult to disprove and equally difficult to prove. It certainly should not be so as regards the major form of epilepsy. Yet among the thousand and thirty persons of British genius I was only able to find epilepsy mentioned twice, and in both cases incorrectly, for the National Biographer had attributed it to Lord Herbert of Cherbury through misreading a passage in Herbert's _Autobiography_, while the epileptic fits of Sir W.R. Hamilton in old age were most certainly not true epilepsy. Without doubt, no eugenist could recommend an epileptic to become a parent. But if epilepsy has no existence in British men of genius it is improbable that it has often occurred among their parents. The loss to British genius through eugenic activity in this sphere would probably, therefore, have been _nil_.

Putting aside British genius, however, one finds that it has been almost a commonplace of alienists and neurologists, even up to the present day, to present glibly a formidable list of mighty men of genius as victims of epilepsy. Thus I find a well-known American alienist lately making the unqualified and positive statement that "Mahomet, Napoleon, Moliere, Handel, Paganini, Mozart, Schiller, Richelieu, Newton and Flaubert" were epileptics, while still more recently a distinguished English neurologist, declaring that "the world's history has been made by men who were either epileptics, insane, or of neuropathic stock," brings forward a similar and still larger list to illustrate that statement, with Alexander the Great, Julius Caesar, the Apostle Paul, Luther, Frederick the Great and many others thrown in, though unfortunately he fails to tell us which members of the group he desires us to regard as epileptic. Julius Caesar was certainly one of them, but the statement of Suetonius (not an unimpeachable authority in any case) that Caesar had epileptic fits towards the close of his life is disproof rather than proof of true epilepsy. Of Mahomet, and St. Paul also, epilepsy is alleged. As regards the first, the most competent authorities regard the convulsive seizures attributed to the Prophet as perhaps merely a legendary attempt to increase the awe he inspired by unmistakable evidence of divine authority. The narrative of St. Paul's experience on the road to Damascus is very unsatisfactory evidence on which to base a medical diagnosis, and it may be mentioned that, in the course of a discussion in the columns of the _British Medical Journal_ during 1910, as many as six different views were put forward as to the nature of the Apostle's "thorn in the flesh." The evidence on which Richelieu, who was undoubtedly a man of very fragile constitution is declared to be epileptic, is of the very slenderest character. For the statement that Newton was epileptic there is absolutely no reliable evidence at all, and I am quite ignorant of the grounds on which Mozart, Handel and Schiller are declared epileptics. The evidence for epilepsy in Napoleon may seem to carry slightly more weight, for there is that in the moral character of Napoleon which we might very well associate with the epileptic temperament. It seems clear that Napoleon really had at times convulsive seizures which were at least epileptoid. Thus Talleyrand describes how one day, just after dinner (it may be recalled that Napoleon was a copious and exceedingly rapid eater), passing for a few minutes into Josephine's room, the Emperor came out, took Talleyrand into his own room, ordered the door to be closed, and then fell down in a fit. Bourrienne, however, who was Napoleon's private secretary for eleven years, knew nothing about any fits. It is not usual, in a true epileptic fit, to be able to control the circumstances of the seizure to this extent, and if Napoleon, who lived so public a life, furnished so little evidence of epilepsy to his environment, it may be regarded as very doubtful whether any true epilepsy existed, and on other grounds it seems highly improbable.[3]

Of all these distinguished persons in the list of alleged epileptics, it is naturally most profitable to investigate the case of the latest, Flaubert, for here it is easiest to get at the facts. Maxime du Camp, a friend in early life, though later incompatibility of temperament led to estrangement, announced to the world in his _Souvenirs_ that Flaubert was an epileptic, and Goncourt mentions in his _Journal_ that he was in the habit of taking much bromide. But the "fits" never began until the age of twenty-eight, which alone should suggest to a neurologist that they are not likely to have been epileptic; they never occurred in public; he could feel the fit coming on and would go and lie down; he never lost consciousness; his intellect and moral character remained intact until death. It is quite clear that there was no true epilepsy here, nor anything like it.[4] Flaubert was of fairly sound nervous heredity on both sides, and his father, a distinguished surgeon, was a man of keen intellect and high character. The novelist, who was of robust physical and mental constitution, devoted himself strenuously and exclusively to intellectual work; it is not surprising that he was somewhat neurasthenic, if not hysterical, and Dumesnil, who discusses this question in his book on Flaubert, concludes that the "fits" may be called hysterical attacks of epileptoid form.

It may well be that we have in Flaubert's case a clue to the "epilepsy" of the other great men who in this matter are coupled with him. They were nearly all persons of immense intellectual force, highly charged with nervous energy; they passionately concentrated their energy on the achievement of life tasks of enormous magnitude, involving the highest tension of the organism. Under such conditions, even in the absence of all bad heredity or of actual disease, convulsive discharges may occur. We may see even in healthy and sound women that occasionally some physiological and unrelieved overcharging of the organism with nervous energy may result in what is closely like a hysterical fit, while even a violent fit of crying is a minor manifestation of the same tendency. The feminine element in genius has often been emphasised, and it may well be that under the conditions of the genius-life when working at high pressure we have somewhat similar states of nervous overcharging, and that from time to time the tension is relieved, naturally and spontaneously, by a convulsive discharge. This, at all events, seems a possible explanation.

It is rather strange that in these recklessly confident lists of eminent "epileptics" we fail to find the one man of distinguished genius whom perhaps we are justified in regarding as a true epileptic. Dostoievsky appears to have been an epileptic from an early age; he remained liable to epileptic fits throughout life, and they plunged him into mental dejection and confusion. In many of his novels we find pictures of the epileptic temperament, evidently based on personal experience, showing the most exact knowledge and insight into all the phases of the disease. Moreover, Dostoievsky in his own person appears to have displayed the perversions and the tendency to mental deterioration which we should expect to find in a true epileptic. So far as our knowledge goes, he really seems to stand alone as a manifestation of supreme genius combined with epilepsy. Yet, as Dr. Loygue remarks in his medico-psychological study of the great Russian novelist, epilepsy only accounts for half of the man, and leaves unexplained his passion for work; "the dualism of epilepsy and genius is irreducible."

There is one other still more recent man of true genius, though not of the highest rank, who may possibly be counted as epileptic: Vincent van Gogh, the painter.[5] A brilliant and highly original artist, he was a definitely abnormal man who cannot be said to have escaped mental deterioration. Simple and humble and suffering, recklessly sacrificing himself to help others, always in trouble, van Gogh had many points of resemblance to Dostoievsky. He has, indeed, been compared to the "Idiot" immortalised by Dostoievsky, in some aspects an imbecile, in some aspects a saint. Yet epilepsy no more explains the genius of van Gogh than it explains the genius of Dostoievsky.

Thus the impression we gain when, laying aside prejudice, we take a fairly wide and impartial survey of the facts, or even when we investigate in detail the isolated facts to which significance is most often attached, by no means supports the notion that genius springs entirely, or even mainly, from insane and degenerate stocks. In some cases, undoubtedly, it is found in such stocks, but the ability displayed in these cases is rarely, perhaps never, of any degree near the highest. It is quite easy to point to persons of a certain significance, especially in literature and art, who, though themselves sane, possess many near relatives who are highly neurotic and sometimes insane. Such cases, however, are far from justifying any confident generalisations concerning the intimate dependence of genius on insanity.

We see, moreover, that to conclude that men of genius are rarely or never the offspring of a radically insane parentage is not to assume that the parents of men of genius are usually of average normal constitution. That would in any case be improbable. Apart from the tendency to convergent heredity already emphasised, there is a wider tendency to slight abnormality, a minor degree of inaptness for ordinary life in the parentage of genius. I found that in 5 per cent. cases (certainly much below the real mark) of the British people of genius, one parent, generally the father, had shown abnormality from a social or parental point of view. He had been idle, or extravagant, or restless, or cruel, or intemperate, or unbusinesslike, in the great majority of these cases "unsuccessful." The father of Dickens (represented by his son in Micawber), who was always vainly expecting something to turn up, is a good type of these fathers of genius. Shakespeare's father may have been of much the same sort. George Meredith's father, again, who was too superior a person for the outfitting business he inherited, but never succeeded in being anything else, is another example of this group of fathers of genius. The father in these cases is a link of transition between the normal stock and its brilliantly abnormal offshoot. In this transitional stage we see, as it were, the stock _reculer pour mieux sauter_, but it is in the son that the great leap is made manifest.

This peculiarity will serve to indicate that in a large proportion of cases the parentage of genius is not entirely sound and normal. We must dismiss absolutely the notion that the parents of persons of genius tend to exhibit traits of a grossly insane or nervously degenerate character. The evidence for such a view is confined to a minute proportion of cases, and even then is usually doubtful. But it is another matter to assume that the parentage of genius is absolutely normal, and still less can we assert that genius always springs from entirely sound stocks. The statement is sometimes made that all families contain an insane element. That statement cannot be accepted. There are many people, including people of a high degree of ability, who can trace no gross mental or nervous disease in their families, unless remote branches are taken into account. Not many statistics bearing on this point are yet available. But Jenny Roller, in a very thorough investigation, found at Zurich in 1895 that "healthy" people had in 28 per cent. cases directly, and in 59 per cent. cases indirectly and altogether, a neuropathic heredity, while Otto Diem in 1905 found that the corresponding percentages were still higher--33 and 69. It should not, therefore, be matter for surprise if careful investigation revealed a traceable neuropathic element at least as frequent as this in the families which produce a man of genius.

It may further, I believe, be argued that the presence of a neuropathic element of this kind in the ancestry of genius is frequently not without a real significance. Aristotle said in his _Poetics_ that poetry demanded a man with "a touch of madness," though the ancients, who frequently made a similar statement to this, had not our modern ideas of neuropathic heredity in their minds, but merely meant that inspiration simulated insanity. Yet "a touch of madness," a slight morbid strain, usually neurotic or gouty, in a preponderantly robust and energetic stock, seems to be often of some significance in the evolution of genius; it appears to act, one is inclined to think, as a kind of ferment, leading to a process out of all relation to its own magnitude. In the sphere of literary genius, Milton, Flaubert, and William Morris may help to illustrate this precious fermentative influence of a minor morbid element in vitally powerful stocks. Without some such ferment as this the energy of the stock, one may well suppose, might have been confined within normal limits; the rare and exquisite flower of genius, we know, required an abnormal stimulation; only in this sense is there any truth at all in Lombroso's statement that the pearl of genius develops around a germ of disease. But this is the utmost length to which the facts allow us to go in assuming the presence of a morbid element as a frequent constituent of genius. Even then we only have one of the factors of genius, to which, moreover, undue importance cannot be attached when we remember how often this ferment is present without any resultant process of genius. And we are in any case far removed from any of those gross nervous lesions which all careful guardianship of the race must tend to eliminate.

Thus we are brought back to the point from which we started. Would eugenics stamp out genius? There is no need to minimise the fact that a certain small proportion of men of genius have displayed highly morbid characters, nor to deny that in a large proportion of cases a slightly morbid strain may with care be detected in the ancestry of genius. But the influence of eugenic considerations can properly be brought to bear only in the case of grossly degenerate stocks. Here, so far as our knowledge extends, the parentage of genius nearly always escapes. The destruction of genius and its creation alike elude the eugenist. If there is a tendency in modern civilisation towards a diminution in the manifestations of genius--which may admit of question---it can scarcely be due to any threatened elimination of corrupt stocks. It may perhaps more reasonably be sought in the haste and superficiality which our present phase of urbanisation fosters, and only the most robust genius can adequately withstand.

[1] A Danish alienist, Lange, has, however, made an attempt on a statistical basis to show a connection between mental ability and mental degeneracy. (F. Lange, _Degeneration in Families_, translated from the Danish, 1907). He deals with 44 families which have provided 428 insane or neuropathic persons within a few generations, and during the same period a large number also of highly distinguished members, Cabinet ministers, bishops, artists, poets, etc. But Lange admits that the forms of insanity found in these families are of a slight and not severe character, while it is clear that the forms of ability are also in most cases equally slight; they are mostly "old" families, such as naturally produce highly-trained and highly placed individuals. Moreover, Lange's methods and style of writing are not scientifically exact, and he fails to define precisely what he means by a "family." His investigation indicates that there is a frequent tendency for men of ability to belong to families which are not entirely sound, and that is a conclusion which is not seriously disputed.

[3] Dr. Cabanes (_Indiscretions de l'Histoire_, 3rd series) similarly concludes that, while in temperament Napoleon may be said to belong to the epileptic class, he was by no means an epileptic in the ordinary sense. Kanngiesser (_Prager Medizinische Wochenschrift_, 1912, No. 27) suggests that from his slow pulse (40 to 60) Napoleon's attacks may have originated in the heart and vessels.

[4] Genuine epilepsy usually comes on before the age of twenty-five; it very rarely begins after twenty-five, and never after thirty. (L.W. Weber, _Muenchener Medizinische Wochenschrift_, July 30th and Aug. 6th, 1912.) In genuine epilepsy, also, loss of consciousness accompanies the fits; the exceptions to this rule are rare, though Audenino, a pupil of Lombroso, who sought to extend the sphere of epilepsy, believes that the exceptions are not so rare as is commonly supposed (_Archivio di Psichiatria_, fasc. VI., 1906). Moreover, true epilepsy is accompanied by a progressive mental deterioration which terminates in dementia; in the Craig Colony for Epileptics of New York, among 3,000 epileptics this progressive deterioration is very rarely absent (_Lancet_, March 1st, 1913); but it is not found in the distinguished men of genius who are alleged to be epileptic. Epileptic deterioration has been elaborately studied by MacCurdy, _Psychiatric Bulletin_, New York, April, 1916.

[5] See, _e.g._, Elizabeth du Quesne van Gogh, _Personal Recollections of Vincent van Gogh_, p. 46. These epileptic attacks are, however, but vaguely mentioned, and it would seem that they only appeared during the last years of the artist's life.

THE PRODUCTION OF ABILITY

The growing interest in eugenics, and the world-wide decline in the birth-rate, have drawn attention to the study of the factors which determine the production of genius in particular and high ability in general. The interest in this question, thus freshly revived and made more acute by the results of the Great War, is not indeed new. It is nearly half a century since Galton wrote his famous book on the heredity of genius, or, as he might better have described the object of his investigation, the heredity of ability. At a later date my own _Study of British Genius_ collectively summarised all the biological data available concerning the parentage and birth of the most notable persons born in England, while numerous other studies might also be named.

Such investigations are to-day acquiring a fresh importance, because, while it is becoming realised that we are gaining a new control over the conditions of birth, the production of children has itself gained in importance. The world is no longer bombarded by an exuberant stream of babies, good, bad, and indifferent in quality, with Mankind to look on calmly at the struggle for existence among them. Whether we like it or not, the quantity is relatively diminishing, and the question of quality is beginning to assume a supreme significance. What are the conditions which assure the finest quality in our children?

A German scientist, Dr. Vaerting, of Berlin, published on the eve of the War a little book on the most favourable age in parents for the production of children of ability (_Das guenstigste elterliche Zeugungsalter_).[1] He approaches the question entirely in this new spirit, not as a merely academic topic of discussion, but as a practical matter of vital importance to the welfare of society. He starts with the assertion that "our century has been called the century of the child,"[2] and for the child all manner of rights are now being claimed. But the prime right of all, the right of the child to the best ability that his parents are able to transmit to him, is never even so much as considered. Yet this right is the root of all children's rights. And when the mysteries of procreation have been so far revealed as to enable this right to be won, we shall, at the same time, Dr. Vaerting adds, renew the spiritual aspect of the nations.

The most easily ascertainable and measurable factor in the production of ability, and certainly a factor which cannot be without significance, is the age of the parents at the child's birth. It is this factor with which Vaerting is mainly concerned, as illustrated by over one hundred German men of genius concerning whom he has been able to obtain the required data. Later on, he proposes to extend the inquiry to other nations.
