Of old, the mother of Mencius chose a neighbourhood; and when her child would not learn, she broke the shuttle from the loom. Tou of the Swallow Hills had the right method. He taught five sons, each of whom raised the family reputation. To feed without teaching is the father's fault. To teach without severity is the teacher's laziness. If the child does not learn, this is not as it should be. If he does not learn while young, what will he be when old? If jade is not polished, it cannot become a thing of use. If a man does not learn, he cannot know his duty towards his neighbour. He who is the son of a man, when he is young should attach himself to his teachers and friends, and practise ceremonial usages.
