But if such fears haunt the students about to enter Harvard College, who are young men drawn from the better educated and more well-to-do classes, we may be sure that fear plays even a larger part in producing the sufferings of patients such as we examine and treat in a public dispensary. For such patients are very apt to be influenced by groundless rumors, panics, neighborhood gossip. They are prone to believe medical lies which they read in newspapers and in the leaflets and circulars sent to them by charlatans. Almost all their medical education comes to them from such sources, and is made up of a mass of systematic falsehoods designed to excite fear and to produce symptoms by suggestion. Now if it is true that even among educated and relatively self-conscious classes the most troublesome and incapacitating fears are those which are but dimly known to the patient himself, this is sure to be still more frequently the case among dispensary patients. It is especially difficult and especially important, therefore, that their fears should be understood and brought to light through the investigations of some one who has time, patience, and tact to devote to the task. This cannot be the task of the physician who sees neurological cases in the dispensary, any more than the psychological twists and tangles of the tuberculous patient can be followed out by the specialist in tuberculosis who examines the patient's lungs. It is the proper task of the social worker. When she has brought the patient's fears to light, when she understands the details of his malady, she can communicate these facts to the physician. He then can exorcise the unclean spirits with the full authority of his medical position. Just here one sees a good example of the proper coöperation between the physician and the social worker in the dispensary. Each brings to light certain elements in the diagnosis. But in the end the physician must unite all the knowledge accumulated either by himself or by his social assistants, and thus must be enabled to act for the patient's benefit on the basis of a body of information much larger than he could have secured alone.
