The moral education of the youth is also of the greatest importance. A child must grow to recognize a father in every elderly man, a mother in every elderly woman, a sister in girls of his age, and a brother in boys like himself. In this way the obligations of one soul to another in this world will be better understood. When a youth considers his duty only to someone closely related to him, and not to the others, he becomes limited; his point of view becomes narrowed. How much better the world would be if every young man considered it his duty to take care of and be responsible for every young girl as he would for his own sister; there would not be so much sorrow and disappointment. The greatest moral a youth could be taught is to understand his obligations to others, in order to fill his place fittingly in the scheme of life.
