In criticism of the attitude of the commission, it may certainly be held that they underestimated the significance of what they saw and used the term "imagination" in a sense both vague and uncritical; and yet the tenor of their conclusions was as wholesome as it was justifiable. They were primarily concerned with the correctness of the proposed explanation of the phenomena, and with the value of the curative procedures; and on these points their verdict is logically reached and forcibly stated. The psychic element in the guidance of conduct as in the treatment of diseases they were prepared to acknowledge, but not as an indorsement of animal magnetism. "In searching for an imaginary cause for animal magnetism, the actual power which man exercises over his fellow-beings without the immediate and evident intervention of a physical agent, is recognized." Their tests evidence their appreciation of the efficacy of suggestion, a power which they admit "can be elaborated to an art." While it may properly be urged that the report contributed to the postponement of the scientific study of this class of phenomena, its admirable logical qualities entitle its authors to the gratitude and honorable remembrance of mankind. Indeed, in deference to the excited state of public opinion of the time, they subjected themselves and others to most painstaking tests, assuming the burden of disproof, and treating Mesmer's arbitrary attitude with more than scientific fairness. Their verdict not only destroyed Mesmer's pretensions, but held out a rational, though in our present lights an inadequate, interpretation of the phenomena, then so sensationally presented to an excited and distraction-loving public.
