Before puberty, the effect o the vice upon the genital organs is to ca — John Harvey Kellogg

"JUST in proportion as the perpetuation of the race is more important than the existence of any single individual, the organs of reproduction may in a certain sense be said to rank higher than any other organs of the human frame, since to them is intrusted the important duty of performing that most marvelous of all vital processes, the production of human beings. That this high rank in the vital economy is recognized by nature, is shown by the fact that he has attached to the abuse of the generative function the most terrible penalties which can be inflicted upon a living being. The power of abuse seems to be almost exclusively confined to man; hence, we find him the only one of all living creatures subject of the awful penalties of sexual transgression. The “use” of the reproductive function is perhaps the highest physical act of which man is capable; its “abuse” is certainly one of the most grievous outrages against nature which t is possible for him to perpetrate No observing person an doubt that sexual relations of men and women determine in a great degree their happiness or misty in life. This subject, then, deserves due attention and careful consideration. It is of no use to scout it; for it will inevitably obtrude itself upon us, no matter how sedulously we attempt to avoid it. It can be rightly considered only with the most perfect candor, with the mind unbiased by passion, and prayerfully anxious to know and “do” what is right."

"In order to make more clear and comprehensible the teachings of nature respecting the laws regulating the sexual function, and the evils resulting from their violation, it has seemed necessary to preface the practical part of the subject by a concise description of the anatomy of reproduction. In this portion of the work especial pains has been taken to avoid anything like indelicacy of expression yet it has not been deemed advisable to sacrifice perspicuity of ideas to any prudish notions of modesty. It is hoped that the reader will bear in mind that the language of science is always chaste in itself, and that it is only through a corrupt imagination that it becomes invested with impurity."

"Sexual Precocity.-There are two periods in human life when the sexual instincts should be totally dormant; and they are so when nature is not perverted. The first is the period reaching from infancy to puberty. The second is the period reached in advanced age. If raised strictly in accordance with natural law, children would have no sexual notions or feelings before the occurrence of puberty. No prurient speculation about sexual matters would enter their heads. Until that period, the reproductive system should lie dormant in its undeveloped state. No other feeling should be exhibited between the sexes than that brotherly and sisterly affection which is so admirable and becoming. Fortunate, indeed, would it be for humanity if this natural state always existed; but it is a lamentable fact that it is rarely seen in modern homes. Not infrequently, evidences of sexual passion are manifested before the child has hardly learned to walk. It has been suggested that this precocity is nothing remarkable or unnatural, since it is often seen in little lambs and other young animals. To this it is only necessary to reply that the development of the sexual instincts perfectly correspond with the longevity of the animal; if short-lived, like the sheep, only a short period intervenes between birth and the attainment of the sexual appetite and virility. If the animal is intended for long life, as is the case with man, these manifestation s are delayed until a much later period, or should be. Certain insects perform the sexual act as soon as they acquire their perfect form; but they perish as soon as the act is completed."

"The premature development of the sexual inclination is not alone repugnant to all we associate with the term childhood, but is also fraught with danger to dawning manhood. On the judicious treatment of a case such as has been sketched, it probably depends whether the dangerous propensity shall be so kept in check as to preserve the boy’s health and innocence, or whether one more shattered constitution and wounded conscience shall be added to the victims of sexual precocity and careless training. It ought not to be forgotten that in such a cases a quasi-sexual power often accompanies these premature sexual inclinations. Few, perhaps, except medical men, know how early in life a mere infant may experience erections. Frequently it may be noticed that a little child, on being taken out of bed in the morning, cannot make water at once. It would be well if it were recognized by parents and nurses that this often depends upon a more or less complete erection."

"Often the manifestation of sexual precocity is less gross, but almost equally fraught with danger, nevertheless. Dr. Acton, a distinguished English surgeon whom we shall frequently quote, makes the following excellent remarks upon this subject:- “Slight signs are sufficient to indicate when a boy has this unfortunate tendency. He shows marked preferences. You will see him single out one girl, and evidently derive and unusual pleasure (for a boy) in her society. His “penchant” does not take the ordinary form of a boy’s good nature, but little attentions that are generally reserved for a later period prove that his feeling is different, and sadly premature. He may be apparently healthy, and fond of playing with other boys; still there are slight, but ominous, indications of propensities fraught with danger to himself. His play with the girl is different from his play with his brothers. His kindness to her is a little too ardent. He follows her, he does not know why. He fondles her with a tenderness painfully suggestive of a vague dawning of passion. No one can find fault with him. He does nothing wrong. Parents and friends are delighted at his gentleness and politeness, and not a little amused at the early flirtation. If they were wise, they would rather feel profound anxiety; and he would be an unfaithful or unwise medical friend who did not if an opportunity occurred, warn them that such a boy, unsuspicious and innocent as he is, ought to be carefully watched and removed from every influence calculated to foster his abnormal propensities."

"The publishers of this work offer no apology for presenting it to the reading public, since the wide prevalence of the evils which is exposes is sufficient warrant for its publication. The subjects with which it deals are of vital consequence to the human race ; and it is of the utmost importance that every effort should be made to dispel the gross ignorance which almost universally prevails, by the wide diffusion, in a proper manner, of information of the character contained in this volume."
