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. Probably the worst thing in the world for those who have any inherited tendency to disequilibration of mind is to have an occupation in life which involves strains and stresses of emotion. The gambler, the speculator, the man who risks his all on some attempt to make a great deal of money, are much more prone to develop insanity than those who have occupations in life at which they work from day to day for a moderate wage, and who get their joy in life out of the fulfillment of domestic duties. Almost needless to say religion has always discouraged gambling and such speculation as resembles it very closely, and the whole tendency of religious influence is to make people so satisfied with their lot in life that they will not take the risks which involve the {213} vehement mental emotions so likely to disturb those with inherited predispositions toward irrationality. Undoubtedly religion has in this way saved a great many men from serious developments in mental alienation which might have come had they felt themselves free to take up the riskier avocations in life from which they were deterred by the feeling of religious disapproval. After the tendency to exaggeration of the ego and delusions of grandeur, the most common symptom of incipient insanity is delusion of persecution. As regards this, once more, the religious feeling of trust in Providence and the conviction that God will somehow take care of them keeps many people from allowing their delusions of persecution to manifest themselves so soon or so violently as would otherwise be the case. Only comparatively rarely do religious minded people in the midst of their delusions of persecution commit crimes, being deterred therefrom by the underlying consciousness of the wrongness of their acts in taking judgment on their persecutors into their own hands, even though they may have yielded to a belief in their delusions. It is true that a certain number of religious-minded people do commit crime under the influence of delusions, but these are rarer than the cases which occur in people who have never had any sense of religious morality.
