Excerpt from A Treatise on Nervous and Mental Diseases, for Students and Practitioners of Medicine This book is an endeavor to put a working kwledge of nervous and mental diseases into the hands of students and practitioners. A mere compilation, even of an encyclopaedia, would have been comparatively an easy task, calling only for a judicious aggregation of material. In contradistinction, the purpose and limits of a treatise require the selection and clinical verification of facts, and to this most important element of my work the leisure of seven years has been devoted, only two of which, however, have been required for the actual composition. A teacher must kw what to omit, as the force and permanence of his teachings will depend upon his strict avoidance of n-essentials. Superfluous kwledge, like surplus food, may clog the activity of the mind, and in department of medical science is the temptation to expansion and speculation more enticing than in neurology. Keenly appreciating the patient toil of the scientists, to whom we owe most of our kwledge, I have held the task of the physician in yet higher esteem, as the latter must make utilitarian application of all the facts collected by the former. There can be loftier aim in medicine than the relief of human suffering, and to this end I have endeavored to glean from the many departments of medical science what they could contribute. Whether Americans are more prone to nervous disease than other races, or whether it is that our democratic principles set a higher value upon the individual, his comfort and health, than is customary elsewhere, it is yet certain that Europeans, in investigating disease, regard the patient simply as its vehicle, whilst Americans go one step further, and deem the cure all-essential.
