In the first place, then, I would appeal to the clergy to inform themselves as to the limitation of ‘spiritual healing,’ according to the immense mass of evidence which has been collected and does enable us to lay down those limitations with sufficient accuracy for the practical purpose of life; and to act as wise advisers to their people in this matter. (2) The clergy will do well to remember that a great deal of bodily _ill-health_ may exist quite independently of bodily _disease_. These cases are commoner than cases of organic malady. There is plenty of scope for ameliorative work in connexion with them. At the risk of being thought egotistical, I may be allowed to quote a case which recently came under my own observation, and which is typical of a large number of others. A young man, who was clearly very far from being of a neurotic or hysterical type, came to me complaining of severe pain in the region of the heart. It had, according to his account, been gradually increasing for some time. It frequently came on after he had run upstairs, and on one occasion had been intense after running to catch a train. It was sometimes accompanied by violent palpitation and breathlessness, and had no relation to food. Would I tell him if his heart was all right? I examined the heart and could find no trace of any abnormal condition. Nor could I find any evidence of anything in the abdomen which would be likely to account for the pain. I told him that his heart was absolutely sound and that there appeared to be nothing to suggest disease anywhere. A rather careful diet would do him no harm. If it did not do any good, it would be easy enough to prescribe a tonic, but I did not think it necessary. I never expected to see him again. Five months later, however, he called and explained with much gravity that he had come to thank me for ‘curing his heart.’ I then remembered the case, and was fairly staggered. ‘But bless my soul,’ I said rather brusquely, ‘there never was anything the matter with your heart.’ ‘No,’ he replied, this time with a quiet smile, ‘I know there wasn’t. All I can say is that from the time you told me it was all right, the pain disappeared, and I have never had any return of it. But, look here, when it was there, _the pain was real_.’ I have no doubt it was. To label all such cases as ‘hysterical,’ ‘neurotic,’ and so on (in the ordinary connotation of these terms) is utterly unscientific. This young fellow was a sensible, cheerful, rather unimaginative youth without a trace of ‘_neurasthenia_’ about him. Yet, by coming to believe that his heart was diseased, he had quite unconsciously so excited the higher centres that the vagus nerve returned exactly the impressions to the brain which would be conveyed by various morbid organic conditions.
