It is seldom that there emanates from the pen of a doctor a book which, concerning any physical disorder, minimizes the efforts of the medical practitioner. While this author-physician gives full credit to the conscientious physician for the great service he is able to render in all other spheres of his profession, he wholly denies the necessity for medical care in cases of nervous breakdown, and discounts liberally the benefits to be derived from professional advice except in so far as the doctor is the patient's counselor and dictator as to what and how and how much he shall eat and drink, and the way he shall employ his time. Any discourse is valuable which incites a man having a marked tendency to depressing, morbid ideas, to rid himself of them. Dr. Hinkle helps the sufferer to gain that confidence and cheer which result from knowledge of certain immunity from dreaded ills and positive assurance of recovery by mere regulation of food or employment along the lines of simple, everyday living. But that alone is not sufficient. It is made quite clear that no one thing by itself will insure a cure of "nerves." The cure must come through common sense exerted along several related avenues of endeavor. No matter how steadfastly one may adhere to directions as to abstaining from harmful food and injurious methods of partaking of those foods which are beneficial, if he spends the larger portion of his time idly rocking in a convenient arm chair, exerting neither body nor mind nor will, that which might be gained by proper nutrition is largely nullified by lack of physical exercise and mental activity. That this little book may serve as a spur to the bodily self-denial and self-repression and the intellectual and spiritual uplift which make for character-building, is the very evident goal of its writer. From self-analysis and self-cure he has worked out a philosophy--a system or _art_--by which those afflicted with nervous breakdown may be healed. And by putting into print the result of his practical experiments in diet and exercise he has broadened immeasurably the scope of his helpfulness to all nervebound sufferers by placing within their reach the simplest of measures by which release is secured from a condition which wholly incapacitates for active service or even for quiet, everyday usefulness. It is because the things Dr. Hinkle advises are so commonplace, and because the doing of them day after day, year in and year out, is so monotonous, that people will be tempted to disregard or make light of their helpfulness. But the commonplace things which make up life are all important, as Susan Coolidge has so aptly expressed in these lines which fittingly illustrate the author's thought:
