In recent years we have come to study much more closely this suggestive element and to appreciate better its true value. Suggestion has always been an important factor in therapeutics, but has been used indeliberately and indirectly rather than with careful forethought. Not that the great thinkers in medicine have not known its value and have not used it deliberately on appropriate occasions, but that the profession generally has been so much occupied with the merely material means of curing that practitioners have not realized the influence for good of the psychotherapeutic factors they were unconsciously employing. The history of the phases of psychotherapy brings out clearly how much it has always meant in the curing of human ills. Constancy of Psychotherapy in Medicine.--Though we are prone to think of it as coming to attention in our time, psychotherapy has played an important role in every phase of the history of medicine. It has always been at work, though usually under other names, and has been effectively used without conscious direction. Germs and their pernicious activity were not recognized before our time, yet many definite precautions against them, such as cooking of food and the keeping of perishable goods on ice, which now seem to be the direct result of our knowledge of bacteriology, were commonly practiced. The influence of the mind on the body exerted itself quite apart from man's recognition of its place or appreciation of its power. When employed unconsciously it was in many ways even more effective than it will be when a consciousness of the means by which it is applied becomes more general. For most people are unwilling to confess that their minds exercise as much influence as now proves to be the case, and that over-solicitude means so much in inhibiting the curative powers of nature, and that it is this which is favorably affected by psychotherapy. The great physicians employed psychotherapy very commonly, and on that account many of their disciples were inclined to think that they were neglectful of medication and other remedial measures. At all times physicians have had to be large-minded and have had to recognize the limitations of medicine in {3} their own time, to turn to other agents and to appreciate how much their own influence on the patient and that of the patient on himself meant for the relief of symptoms and the increase of resistive vitality.
