Clouston, the well-known English authority on mental diseases, whose opinion is founded on many years of personal observation, in his book on "Unsoundness of Mind" [Footnote 6] has put the relationship between religion and mental disease very clearly. He said: "It is true that religion, touching as it does, in the most intense way the emotional nature and the spiritual instincts of mankind, sometimes appears to cause and is often mixed up with insanity. But in nearly all such cases the brain of the individual was originally unstable, specially emotional, oversensitive, hyperconscientious and often somewhat weak in the intellectual and inhibitory faculties and, if looked for, other causes will usually be found." He had said just before, "To talk of 'religious insanity' as if it were a definite and definable form is in my judgment a mistake."
[Footnote 6: Methuen, London, 1911. ]
So far from prayer—the principal exercise of religion, that is the raising up of the mind to God, either in petition or in resignation—unsettling people's minds, it has exactly the opposite effect. Professor William James, whom most people are not inclined to think of as likely to be an overstrenuous advocate of religion, in his [{209}] well-known essay on "The Energies of Men" has a paragraph in which he quotes from a physician who had had long experience in the care of a great many insane and who did not hesitate to say that prayer was a benefit and not in any sense of the word a detriment to his patients.
"Doctor Thomas Hyslop, of the great West Riding Asylum in England, said last year to the British Medical Association that the best sleep-producing agent which his practice had revealed to him was prayer. I say this, he added (I am sorry here that I must quote from memory) purely as a medical man. The exercise of prayer, in those who habitually exert it, must be regarded by us doctors as the most adequate and normal of all the pacifiers of the mind and calmers of the nerves."
It is recognized as a general rule in asylum practice that when patients begin really to pray, a turn for the better has come in their condition, and they are on the high road to recovery. This does not mean, of course, noisy, wordy praying, but quiet raising of the mind to God and acts of resignation to their condition so long as they may be affected.
There is a very general impression among those who have had most to do with the insane as well as among psychologists in general that religion, instead of favoring the development of insanity, rather inhibits it. Professor Münsterberg, in his "Psychotherapy" dwells particularly on this. Almost needless to say Professor Münsterberg did not wear the special favor of religion in the lists and was in no sense her champion. He is proclaiming simply what he knows and feels to be true.
A very curious reflection on the relations of religion and insanity is to be found in the fact that the marked increase in the insane among the population of all the [{210}] great modern civilized countries and most striking among our own has come since the decay of religion and the decrease of religious belief. The statistics of that increase in the number of the insane are very startling to those who are not familiar with the subject. During a single generation the number of the insane in our institutions has increased to five times what it was before in proportion to the population. There is no doubt that this is due to some extent to the fact that people are much less ready to care for their insane relatives outside of institutions than they were a generation and especially two or three generations ago. We are much less ready to make the personal sacrifices needed to keep our friends at home, which is probably also due to the lowering of our religious sense of obligation in the matter. Fortunately our insane asylums are much better conducted than they were, and this has made people more willing to confide their relatives to them. Giving all due allowance for this, however, there has been an enormous increase in the number of the insane. Such commonwealths as California and Massachusetts, in which there are very large proportions of educated people, present the highest increase in the number of the insane. There are certain critical spirits who would say that it is our education without God and without religion that has fostered this state of affairs, and that it is particularly people of a certain limited intelligence who, when overeducated, lose their faith, who are most prone to lose their minds.
The most important single factor in insanity, not dependent on constitution or heredity but on conduct, is that degeneration of the brain which brings on paresis or general paralysis of the insane. Taken by and large throughout the world generally, nearly one in five of all [{211}] those who die in insane asylums die from this affection. It is the result of an infection usually consequent upon sexual immorality. The disease is inevitably fatal and once it begins it is steadily progressive from the delusions of grandeur so common at the beginning through various delusional states up to absolute dementia and death, which usually takes place in a little more than three years from the beginning of the disease; five years is a long time for a patient to survive. Nothing has done so much to limit the occurrence of this disease as religious influences, and it has increased to become the modern scourge that it is just in proportion as religion has lost its hold upon the mind of the rising generation. The disease is particularly infrequent among clergymen, and while lues from which the disease develops may be contracted innocently, it is very evident that a regular moral life such as is led under the sway of religious principles is the best possible safeguard against the spread of the disease.
After paresis the most serious form of acquired insanity in modern life is that known as alcoholic insanity, due to excess in the taking of spirituous liquors. It is not necessarily inevitable that a man who frequently indulges to excess in alcoholic liquors will become insane any more than that he will suffer from alcoholic neuritis, but a large number of individuals prove susceptible to the toxic effects of alcohol in these ways. There is an inherent liability in their brain and nervous system to degenerate under the influence of alcohol acting as a poison. This is an extremely common form of insanity, but almost needless to say it occurs much less frequently in those who have any religious principles than in those who are without them, because religion protects from the excesses that predispose to these conditions. Clergymen [{212}] very rarely suffer from them and though occasionally clerical patients have developed alcoholic insanity or alcoholic neuritis, these cases on careful investigation oftener proved to be due to certain patent medicines which contained alcohol in large percentage than to any direct consumption of spirituous liquor.
Religion by its calming influence keeps a good many people who have hereditary tendencies to insanity from developing outspoken symptoms of the disease. Religious conviction has a definite efficacy in making people humble instead of conceited, and this is an excellent factor for preventing the tendency to insanity. Nearly always the preliminary sign of insanity is an exaggeration of the ego and a hint at least of delusions of grandeur. People who overrate their importance are often on the road to the asylum. Religion, by inculcating humility, at least lessens this tendency and puts off developments that are inevitable so that many more years of reasonable sanity are enjoyed than would otherwise be the case.
