For the harmonious working of a family, then, we need respect for authority on one side, and self-sacrifice on the other. The father's object must be entirely altruistic--the good of his family. Then only will he be doing his duty as a father, just as a son is not doing his duty unless he shows honour and obedience to his parents. The all-important element which makes possible the working of the family machine, the lubricating oil that eases the bearings, is not merely filial piety without any corresponding feeling on the part of the parent, but rather a certain subtle principle of harmony and self-control permeating every member of the family group, which restrains egoistic propensities and promotes the common good. This is the Chinese term _li_, which in this sense of a quality of the soul is hardly translatable by any single word or combination of words, but is certainly not to be rendered by any such atrocious phrase as "the rules of propriety."[3] Now Confucius saw that the same general principles which govern the family are applicable also to that greatest of families, the State. Here we have the Emperor, in whose hands the supreme authority must lie, exercising functions exactly analogous to those of the father of a family. But if his is the supreme authority, his must also be the supreme responsibility. Veneration and respect are his due, but only because he identifies himself with the good of the people. In public affairs, just as in the home, there must be that same principle of harmony to regulate the relations of governor and governed, otherwise the machine will not work. There must be _li_ here as well, but as it is not possible for the sovereign to maintain with his subjects the personal intimacy which unites a father and his sons, it is necessary to fall back upon symbols, and to give outward and visible expression to the inward sentiments of loyalty and respect which should animate the breast of each member of the nation. These symbols are the rites and ceremonies of which Confucius was considered such a past-master. He saw indeed their full importance as symbols, but he also knew that, divorced from the inward feeling, they were meaningless and without value. In this way it is easy to see how the word _li_, as a human attribute, acquired its various shades of meaning, from the harmony in the soul which prompts action in accordance with true natural instincts, down to ordinary politeness and good manners--also an indispensable lubricant in the lesser dealings of life between man and man.
