No parent who stops with provision for the physical and intellectual demands of his child has done his full duty. It may appear trite to say that he should go further and train the character and the soul; but failure in this essential is a standing indictment against many Christian homes today. Parental indifference to and ignorance of boy-psychology are the causes which have produced untold thousands of delinquent or semi-delinquent boys. Your boy may, and thousands of boys do, weather the storm of adolescence, guided only by the blundering but loving heart which has neither accurate knowledge nor understanding of his nature; but such results are fortuitous rather than certain. More parents have mastered the rules of bridge than have mastered the principles of child-culture. The training of the boy, despite its tremendous personal significance to him and to our homes, is less frequently and less seriously discussed than politics, the weather, or the latest style of dress. Too many boys are reared like their colored sister, Topsy, who “jest growed.” Deep down in our hearts we feel that we know much more than our neighbors about the upbringing of a son, because of our superior intuition and better judgment, even though we have never qualified for the job by study, research, or thought. Too many of us believe we are “natural-born” boy trainers. When our boy goes wrong, it is our profound conviction that it is due wholly to the influence of the bad boys with whom he associates. As a matter of fact, it is just as likely that our Johnny has corrupted his associates as that they are the cause of his moral infractions. Never, under any circumstances, do we blame ourselves either for the poor quality of his training or for permitting his evil associations. His delinquencies reflect on us and hurt our pride, but we palliate the hurt by attributing them to causes which do not involve us. We are too ready to prove an alibi when called to the court of conscience and charged with responsibility. The average parent bitterly resents personal advice relating to the upbringing of his children, but this resentment probably has less relevancy to reading a book on boy-training because it is impersonal in its application and affords the reader the election of taking as much or as little of it to himself as his reason, judgment, vanity, or egotism may dictate. All boys have a common nature whose development proceeds according to fixed laws; but diversities of temperament and character differentiate individuals and thus make each boy an individual problem. The solution of that problem is your job. CHAPTER II PARENTAL RESPONSIBILITY The wayward boy is often the son of a wayward parent.
