At this point, however, the question forcibly presents itself, How does it come to pass in the experience of children that they learn to regard certain lines of action as good and others as bad? You will readily answer, The parent characterizes certain acts as good and others as bad, and the child accepts his definition; and this is undoubtedly true. The parent's word is the main prop of the budding conscience. But how comes the parent's word to produce belief? This is indeed the crucial question touching the development of the moral faculty. Mr. Bain says that the child fears the punishment which the parent will inflict in case of disobedience; that the essential form and defining quality of conscience from first to last is of the nature of dread. He seems to classify the child's conscience with the criminal conscience, the rebel conscience which must be energized by the fear of penalties. But this explanation seems very unsatisfactory. Every one, of course, must admit that the confirmations of experience tend greatly to strengthen the parent's authority. The parent says, You must be neat. The child, if it does as it is bidden, finds an aesthetic pleasure in its becoming appearance. The parent says, You must not strike your little brother, but be kind to him; and the child, on restraining its anger, is gratified by the loving words and looks which it receives in return. The parent says, You must not touch the stove, or you will be burned. The disobedient child is effectually warned by the pain it suffers to be more obedient in future. But all such confirmations are mere external aids to parental authority. They do not explain the feeling of reverence with which even a young child, when rightly brought up, is wont to look up to his father's face. To explain this sentiment of reverence, I must ask you to consider the following train of reasoning. It has been remarked already that the parent should be to the child the visible embodiment of a higher law. This higher law shining from the father's countenance, making its sublime presence felt in the mother's eye, wakens an answering vibration in the child's heart. The child feels the higher presence and bows to it, though it could not, if it tried, analyze or explain what it feels. We should never forget that children possess the capacity for moral development from the outset. It is indeed the fashion with some modern writers to speak of the child as if it were at first a mere animal, and as if reflection and morality were mechanically superadded later on. But the whole future man is already hidden, not yet declared, but latent all the same in the child's heart. The germs of humanity in its totality exist in the young being. Else how could it ever unfold into full-grown morality? It will perhaps serve to make my meaning clearer if I call attention to analogous facts relating to the intellectual faculty. The formula of causality is a very abstract one, which only a thoroughly trained mind can grasp.
