Before I leave this topic, I wish to present to the reader a case somewhat parallel to that of Homœopathy, which may serve to illustrate farther the way in which medical delusions acquire their hold upon the public mind. A clergyman in a small town in Germany, interpreting the passage of Scripture, ‘the prayer of faith shall save the sick,’ as having a literal and an universal application, some years ago went into the practice of medicine among the people of his charge upon this idea. He gives no medicine, but merely visits the sick and prays with them. All kinds of disease, acute and chronic, are submitted to this treatment. He tells those that apply to him, that there is no need of doing so, if they will only themselves repent of their sins, and lift up the prayer of faith. It is only in default of their penitence and faith that his prayers are required. He shows great shrewdness in pointing out the sins of the vicious, to which he attributes their diseases. This adds much to his reputation, and to the mental influence which he exerts upon the sick. He is sincere in his views, and takes no compensation for his services to the sick, which he performs in connexion with his pastoral labors. His success is so great, that no physician has been able to get a living in the place where he resides, and invalids come to him from all the country round, even to the distance of fifty miles. In this instance, there are some of the same elements of success that exist in the case of Homœopathy. His mental influence upon his patients is very decided. He leaves the curative power of nature to act undisturbed. And added to these sources of success may be mentioned, as having a considerable influence, a reformation in the life of some of those whose vices he faithfully points out to them. So far as apparent results are concerned, it is quite as proper to attribute a curative ‘dynamic power’ to the prayers of this clergyman, as to the infinitesimal doses of Hahneman.
