The author presents a practical, lecture-style guide to sexual health in childhood, explaining physical, emotional, and intellectual development through a simple chart that shows feelings and bodily impulses dominating the intellect in early years. He argues that this imbalance creates special vulnerability to sexual abnormality and disease unless parents supply deliberate, pure moral and educational guidance. The text examines physiological centers driving adolescent impulses, warns of risks from unchecked imagery or misinformation, and urges guardians to shape wholesome impressions and provide clear, age-appropriate instruction to protect developing bodies and minds.
