Must a child obey without understanding? There is a vast difference between the mentality and experience of the child and of the guardian. Very often the child will not know why it is told, "You must not do it"; and if the child always asked, "Why must I not do it?" then it would be difficult, because very often it cannot even be explained. And very often it had better not be explained; very often it is better that the child only listens to the guardian and does not argue. Just as the musicians in the orchestra are accustomed to look at the conductor's baton, so a baby must be taught to look at the glance of its guardian. And if the guardian is wise enough to conduct the action of the baby from morning till evening by his glance alone, he is sure to train that child to be a most promising soul in the future.
