Insanity may be briefly defined as a disease of the mind. We will not here go into a discussion as to what constitutes real insanity, as to what is understood by insanity in the legal sense of the term, and so on, except to note that we have two divisions.
One is functional insanity. This may be temporary, or periodical, and is due to some external cause, is curable, and is not hereditary. For instance, a person may get insane from a severe shock, from trouble, from anxiety, from a severe accident (such as a shipwreck), from a sudden and total loss of his fortune, of his wife and children (by fire, earthquake, shipwreck or railroad accident). Such insanities are curable and are not transmissible. Another example is what is known as puerperal insanity. Some women during childbirth, due probably to some toxic infection, become insane. This insanity may be extreme and maniacal in character. Still, it often passes away in a few days without leaving any trace and may never return again, or, if it does return, it may return only during another childbirth. This kind of insanity is not transmissible.
The second division is what we call organic insanity. This expresses itself in mania and melancholy, so-called manic-depressive insanity. This is due to a degeneration of the brain-and nerve-tissue and is hereditary.
But, our entire conception as to the hereditary transmissibility of insanity has undergone a radical change. There is hardly another disease the fear of whose hereditary character is responsible for so much anguish and torture. In former years, when there was an insane uncle or aunt or grandparent that fact weighed like a veritable incubus on the entire family.
Every member of the family was tortured by the secret anguish that maybe he or she would be next to be affected by this most horrible of all diseases—disease of the mind. If an ancestral member of the family became insane at a certain age, every member of that family was living in fear and trembling until several years had passed after that critical age, and only then would they begin to breathe freely. Indeed, many people became insane from the very fear of becoming insane. It cannot be subject to any doubt that many people do become mentally unbalanced from the fear that they will become unbalanced. Fear has a tremendous influence on the purely bodily functions, but its influence on the mental functions is incomparably greater, and a person will often get that which he fears he is going to get.
Now the hereditary character of insanity is not taken in the same absolute sense in which it was formerly. While we still consider it a dysgenic factor, yet we recognize the paramount importance of environment; and we know that by proper bringing-up, using the expression bringing-up in its broadest sense—including a proper mental and physical discipline—any hereditary taint can be counteracted. In connection with this subject, the following very recent statistics will prove of interest.
The families of 558 insane persons cared for in the London county asylums were investigated, and, according to reports received from the educational authorities, only 15 of these (less than 3 per cent) had mentally defective children. As to the time of the birth of the children, whether before or after the attack of the insanity, we find the following figures: 56 out of 573 parents had children after their first attack of insanity, and 106 children were born after the onset of insanity in the parent; while the remaining 1259 children were born before the parent became insane.
Altogether, as will be seen from a discussion of the various factors rendering marriage permissible or nonpermissible, I am inclined to consider environment a more important factor than heredity. The purely physical characteristics bear the indelible impress of heredity. But the moral and cultural characteristics, which in the modern civilized man are much more important than the physical, are almost exclusively the results of environment.
