The punishments which the Chinese laws enjoin for unfilial conduct bear witness to the high estimation in which the Chinese moralists and rulers hold the virtue of filial obedience and reverence. Thus a parent may, with the consent of the maternal uncle, require a magistrate to whip to death an unfilial son.[144] A parricide is beheaded, his body cut in pieces, his house torn down, his neighbors are punished, his chief teacher is put to death, and the magistrates of the district in which he lived are degraded or deposed.[145] [Sidenote: Reverence toward superiors] Filial piety is regarded by Chinese moralists as the root out of which grow all other virtues. Immediately out of this root springs the duty of obedience and reverence toward all superiors. This is the corner stone of the Chinese system of political ethics. “In the family life,” in the words of Jernigan, “may be seen the larger life of the empire.”[146] [Sidenote: A conforming to ancient custom] We have here the third of the cardinal duties, the duty which in practice constitutes the heart and core of Chinese morality.[147] The commandment is, Follow the ancients; walk in the trodden paths; let to-day be like yesterday. This duty, as we have already noticed, springs from the Chinese conception of the past as perfect. If that past be perfect, then of course it becomes the duty of living men to make the present like unto it, and in no case to depart from the customs and practices of the fathers. We can easily make the Chinese view in this matter intelligible to ourselves by recalling how we have been wont to regard the religious past of that Hebrew world of which we are the heirs. Sanctity in our minds has attached to it all, and we regard any departure from the teachings and commandments of that past to be a fault, even a species of wickedness deserving eternal punishment. Now in China this idea of sanctity, which among ourselves attaches only to the religious side of life, has attached to all phases of life, to government, to society, to art, to science, to trade and commerce--to all of the ideas, ways, and customs of antiquity. As their fathers did, so must the children do. They must deem worthy what their fathers deemed worthy and love what their fathers loved.[148] He who departs from the beliefs and practices of the ancients is regarded as irreverent and immoral, just as he who with us departs from the beliefs and customs of the fathers in religion is looked upon as presumptuous and irreligious.
