From lack of true knowledge of the natural facts of their own physical organization, young men are often terrified into a resort to quacks, who impose on their ignorance. The young also of both sexes may be tempted into bad habits of self-abuse at the outset of this new life, from being unacquainted with the evils and dangers of vicious indulgence. It is the grave parental duty of both father and mother to be able to direct a child at its first entrance into adult life. At an age varying with climate, race, and temperament, the young man as well as the young woman will experience the healthy discharge, which is a sign that the gradual development of the reproductive organs has attained its final stage. In both its sudden appearance often produces fright; in both it may appear once, with long intervals of recurrence. In the girl it tends gradually (for important natural reasons) to the establishment of a frequent and regularly returning function. In the young man and in the continent unmarried adult, the natural action of these organs is of far less frequent recurrence; it may be of slow and uncertain return, dependent greatly upon the occupation of the mind and general physical state of the individual. In the natural healthy young man, the occasional return of this function, even with a certain degree of periodicity, is a valuable aid to adult self-government. It is impossible to reprobate too strongly the false views of physiology held by those who make no distinction between the natural healthy growth of these functions and their abuse. No Christian physiologist whose observation of facts is enlightened by a knowledge of the possibility of moral growth can commit so fatal an error. It is an insult to the male nature to infer that it is inferior to the female nature because it does not fully possess the power of individual self-balance. The assertion that one human being is dependent on the degradation of another human being for the maintenance of personal health is contradicted by physiological facts as well as social experience.
