The opium habit, to which allusion has also been made, is open to the same objections, and must be abandoned by all who would seek recovery.
PART IV.
DISEASES AND THEIR REMEDIAL TREATMENT.
INTRODUCTION.
Knowledge which is conducive to self-preservation is of primary importance. That great educator, profound thinker, and vigorous writer, Herbert Spencer, has pertinently said that, "As vigorous health and its accompanying high spirits, are larger elements of happiness than any other things whatever, the teaching how to maintain them is a teaching that yields to no other whatever. And therefore we assert that such a course of physiology as is needful for the comprehension of its general truths and their bearings on daily conduct is an all-essential part of a rational education."
Believing that the diffusion of knowledge for the prevention of disease is quite as noble a work as the alleviation of physical suffering by medical skill, we have devoted a large portion of this volume to the subjects of physiology and hygiene. These we have endeavored to present in as familiar a style as possible, that they may be understood by every reader. Freely as we have received light upon these subjects have we endeavored to reflect it again, in hopes that a popular presentation of these matters made plain and easy of comprehension to all people, may lead the masses into greater enjoyment of life—the result of a better preservation of health. This we do in part as a public acknowledgment of our obligations to society, to whom every professional man is a debtor. He belongs to it, is a part of its common stock, and should give as well as receive advantages, return as well as accept benefits. We know of no better way to signify our appreciation of the public confidence and patronage, so generously accorded to us, than to offer this volume to the people at a price less than the actual cost for an edition of ordinary size. This we do as a token of the cordial reciprocation of their good will. In giving to the people wholesome advice, by which they may be enabled to ward off disease and thus preserve the health of multitudes, we believe we shall receive their hearty approval, as well as the approbation of our own conscience, both of which are certainly munificent rewards. We believe that good deeds are always rewarded, and that the physician who prevents sickness manifests a genuine and earnest devotion to the common interests of humanity.
We have no respect for the motives of those medical men who would withhold that information from the people which will direct the masses how to take care of themselves, and thereby prevent much sickness and suffering. Nor is the diffusion of such knowledge antagonistic to the best interests of the true and competent physician. The necessity for his invaluable services can no more be set aside by popularizing physiological, hygienic, and medical truths, than we can dispense with those of the minister and lawyer by the inculcation of the principles of morality in our public schools. The common schools do not lessen the necessity for colleges or universities, but rather contribute to their prosperity. Nor are we so presumptuous as to anticipate that we could possibly make this volume so instructive as to render "every man his own physician." No man can with advantage be his own lawyer, carpenter, tailor, and printer; much less can he hope to artfully repair his own constitution when shattered by grave maladies, which not only impair the physical functions, but weaken and derange the mental faculties. What physician presumes to prescribe for himself, when suddenly prostrated by serious illness? He very sensibly submits to the treatment of another, because he realizes that sickness impairs his judgment, and morbid sensations mislead and unfit him for the exercise of his skill. If this is true of the physician, with how much greater force does it apply to the unprofessional! If a sick sea-captain is unfit to stand at the helm and direct his ship, how utterly incompetent must the raw sailor be when similarly disqualified! Nor is the physician as competent to treat those near and dear to him, when they are suffering from dangerous illness, as another medical man not similarly situated, whose judgment is not liable to be misled by intense anxiety and affectionate sympathy.
Notwithstanding all these facts, however, a knowledge on the part of the unprofessional, of something more than physiology and hygiene, and appertaining more closely to medicine proper, will many times prove valuable.
