A child is intelligent and can easily be brought to notice the difference between people, and to admire the noble and beautiful. It can easily be trained to a healthy discrimination, with an inclination towards all that is sane, wholesome, and vigorous, as being productive of the greatest happiness and pleasure, with a contempt of all uncleanness, and with a fear of the consequences of all unlawfulness. There is no need to punish or to frighten a child, any more than there is any need to feel disgust or fear for a child when it shows an inclination that needs correction; words usually produce the best remembered impressions.
