What then can be done with the young? They must early and authoritatively be told of the wrong, the sin of base self-indulgence, and of every practice that leads to it. If a beginning of immorality is discovered in a child, it must be plainly told and emphatically warned of the serious consequences involved. The child's mother is, as a rule, the best guide and director in infancy. Later on, the Doctor has frequent chances to do so; it comes from him with better grace than from others; and his warning is likely to be minded, because it is clear that he knows and ought to know what he is talking about with regard to bodily consequences. Yet it is always a matter of delicacy; and great care should be taken lest, while pointing out the evil, there be also a stimulus added to a prurient curiosity. Much good sense is required in any given case to decide whether more good or more evil is likely to result from the warning; in doubt of success, it is better to leave the matter alone. "Where ignorance is bliss 'Tis folly to be wise." The safest way of repressing the passion of lust is the provision that an all-wise Providence supplies in Religion, in which God authoritatively forbids all immoral action and even all immoral coveting or desire. Positive dogmatic teaching on this subject is required, especially with the young. You cannot argue with them on this matter as you can with grown people. That is one reason why religious teaching should permeate early education. The Decalogue should be the back-bone of a child's training: and it should be proposed on the authority of God, and explained so as to check not only sinful acts, but also covetings, prurient curiosity, improper reading, immodest looks and thoughts, in a word, whatever paves the way to the walks of sin. The greatest of teachers has Himself laid down the law in this matter: it must be proposed as coming from His divine lips, as it did: "I say to you that whosoever shall look on a woman to lust after her has already committed adultery with her in his heart" (St. Matt. v. 28). The lesson is enforced by these words of the great Apostle: "Neither fornicators, nor adulterers, nor the effeminate ... shall possess the kingdom of God" (1 Cor. vi. 9, 10). True, the child will not realize the full import of such lessons; but he will understand it in due time; and already in early years he will be warned against indulging his nascent passions. It is well that the conscience should be early awakened in this matter; for the more this passion is indulged, the more it craves for further indulgence till it becomes almost uncontrollable.
