In many conditions where the nervous system can have influence a miracle is very difficult of proof from the context. There can, of course, be evident miracles in the cure of some nervous disorders, supposing the diagnosis to be certain. The sudden cure of advanced paresis would be as much a miracle as the sudden replacing of a lost femur. Commonly, however, in neuroses if there is an apparently miraculous healing or similar effect, the supernatural quality can not be established. Suppose Bernadette reported that she had seen the Blessed Virgin at Lourdes: the only safe thing to do in such a case is to deny the apparition until it has been proved. Suppose, secondly, that a patient who has been confined to bed for years by an hysterical paralysis, believed in the reality of the vision, had himself carried to Lourdes, and while at prayer there he suddenly stood up cured. That effect would prove neither the reality of the vision nor the supernatural quality of the cure; nor would it disprove either. We simply can not judge the case, because exactly the same effect has happened hundreds of times from purely natural impressions. If that same paralytic were lying in his bed at home and you set the house afire he would jump up and run. If the patient, however, had been bedridden with a paralysis caused by certain degeneration of nervous tissue, and he were cured in the manner described, that effect would be supernatural, miraculous; always provided there is no error in the medical diagnosis. There is a genuine diabetes and a pseudodiabetes. The latter condition may be diagnosed as true diabetes by a number of physicians, but it is only a symptom of hysteria. If the pseudodiabetes is suddenly cured, this cure may or may not be miraculous, but no one can say which is the truth; the probability is a hundred to one that the cure is altogether natural. There was a flourishing Christian Science congregation established in the west recently upon "miraculous" cure of a case of pseudodiabetes, which some ignorant physicians had called true diabetes, notwithstanding the fact that Christian Science does not believe in either diabetes or false diabetes.
