Place of Personal Influence.--When the antitoxins and directly curative serums seemed about to make for themselves a place in therapeusis, it looked for a time as though this personal element might be entirely superseded. It seemed that all other therapeutic factors must give way to definitely accurate doses of antitoxic principles, directly opposed to the toxins of disease and {70} capable of conquering it. With the success of diphtheria serum, the prospects for scientific therapeutics from the biological standpoint became very promising. Unfortunately, our further experience with antitoxins and therapeutic sera of various kinds has not been satisfactory, and now the medical world is looking elsewhere for progress in therapeutics. This throws us back once more on the old-time therapeutics, and we have to learn to use all their elements. One of the most important of these, if not, as we have suggested, absolutely the most important, the one that in all the many variations of therapeusis has maintained itself, is the personal influence of the physician by which he is able to soothe the patient's fears, allay his anxieties, make him face the situation calmly so that he may not use up any of his vital force in useless worry, but on the contrary employ all his available psychic energy in helping nature to overcome whatever disturbance there is within the organism. This personal influence was for several centuries spoken of as personal magnetism, not merely in the figurative sense in which we now employ that term, but in a literal sense. The implication was that some men possessed within themselves a reservoir of superfluous energy, vital in character, but thought to be related to the force exhibited by the magnet, when it attracted bodies to itself, and made metals for a time magnetic like itself, and which actually passed over from the physician to his patient. We have gotten away from the idea of any physical force flowing from physician to patient, but we know very well that certain physicians are much more capable than others of arousing the vital energies of the patient, sometimes to the extent of making him feel, after treatment, that he has more force than before. The patient feels that something must have been added to his natural powers, though he has only been brought into a state of mind where he can better use his own powers.
