For the average future physician, it would be wiser to omit even the psychiatry studies than those in abnormal psychology. The latter ought to lead him far enough to discriminate early between a mere neurasthenia, for instance, and a beginning of insanity. As soon as the discrimination is perfected and insanity is found, he has to give the case out of his care anyhow and hand it over to the specialist and to the asylum. The knowledge of psychiatric treatment is, therefore, not essential for the average practitioner. But no one can relieve him from the responsibility for those borderland cases, for the hysterias and psychasthenias and neurasthenias, and he can never master them without normal and abnormal psychology. Moreover it must not be forgotten that mental factors may enter into every disease. The psychology of pain, for instance, and of comfort feeling, the psychology of hunger and thirst, of nausea and dizziness, the psychology of the sexual feelings, the psychology of hope and fear, of confidence and discouragement, of laziness and energy, of sincerity and cunningness play their role in almost every sick room. And if the physician haughtily declares that he does not care for the methods of suggestion, it might justly be asked whether he can be a physician at all if he does not apply some suggestions; yes, if his very entrance into the sick room does not suggest relief and improvement from the start. The introduction of a serious study of psychology is the most immediate need of the medical curriculum. Instructorships in abnormal psychology must be created in every medical school; institutes for psychotherapy should soon follow. But in all this, there is nowhere to appear any artificial antithesis between mind and body, any more than between organic and functional diseases; we have discussed all that with full detail. Only the physician who has a thorough psychological preparation can fulfill the manifold demands which modern life must raise; he alone is prepared to cooeperate with the other factors of the community in the development of a sound and healthful nation, to work towards the hygiene of the nervous system and of the mental life; and to correct the injuries which the perversities of our civilization inflict.
