The variety of the psychotherapeutic methods is great and only some types are to be characterized here. But one rule is common to all of them: never use psychotherapeutic methods in a schematic way like a rigid pattern. Schematic treatment is a poor treatment in every department of medicine, but in psychotherapeutics it is disastrous. There are no two cases alike and not only the easily recognizable differences of sex and age, and occupation and education, and financial means, and temperament and capacity are decisive, but all the subtle variations of prejudices and beliefs, preferences and dislikes, family life and social surroundings, ambitions and prospects, memories and fancies, diet and habits must carefully be considered. Every element of a man's life history, impressions of early childhood, his love and his successes, his diseases and his distresses, his acquaintances and his reading, his talent, his character, his sincerity, his energy, his intelligence--everything--ought to determine the choice of the psychotherapeutic steps. As it is entirely impossible to determine all those factors by any sufficient inquiry, most of the adjustment of method must be left to the instinct of the physician, in which wide experience, solid knowledge, tact, and sympathy ought to be blended. Even the way in which the patient reacts on the method will often guide the instinct of the well-trained psychotherapist. It is therefore certainly not enough that the knowledge of the physician simply decide beforehand on a definite course of psychical treatment and leave the carrying out to a well-meaning minister or any other medical amateur who schematically follows the indicated path. The finest adjustment has to come in during the treatment itself and the response of the patient often has to suggest entirely new lines of procedure. More than in any other field of medicine, the physician himself has to extend his influence far beyond the office hours and the strictly medical relations. And yet, on the other hand, there is no department of medicine in which the treatment might not profit by the psychotherapeutic influence. With a few vague words of encouragement mechanically uttered, or with a routine of tricks of suggestion by bread pills and colored water and tuning forks, not much will be gained even in the ordinary physician's practice. Subtle adjustment to the personal needs and to the individual conditions is necessary in every case where the psychical factor is to play an important role. It cannot be denied that the one great obstacle in the work of the routine physician is the lack of time and patience which is needed for successful treatment. To prescribe drugs is always quicker than to influence the mind; to cure a morphinist by hyoscine needs less effort than to cure him by suggestion.
