Again, the Confucian system tends to produce a formal morality. While it is not true, as we have seen, that Confucianism neglects to deal with general principles, right feelings, and motives of action, still it is true that instead of relying upon these there is an immense multitude of precepts and minute rules covering the smallest details of conduct. There are three thousand rules of deportment. This has resulted, and naturally, in the substitution of the letter for the spirit. Even the Master has come to serve as a pattern rather in the outer form of his life than in its informing spirit.[185] Never was there a better illustration of how the letter killeth; for a reliance on exact rules and instructions as to conduct in all conceivable relations and situations has made much of Chinese morality a formal and lifeless thing. The Chinese are governed by a sense of propriety rather than by a sense of duty. Their morality is largely etiquette.[186] It has justly been likened to the morality of the ancient Romans in that it makes manners and morals to be almost interchangeable terms. Especially have the hundreds of rules prescribed for the expression of reverence for superiors tended to empty this part of Chinese morality of reality and sincerity, and to make Chinese official ceremonialism one of the most curious phases of Chinese life. It would seem, further, that the very great emphasis laid by the Chinese moralists upon the duties of children toward their parents has prevented the normal development among the Chinese of that ethical sentiment which among ourselves assigns the duties of parents to infant children an important place in the code of domestic morality. This lack among the Chinese of any deep feeling of parental obligation results in a widespread practice condemned by the conscience of Christian nations. The exposure or destruction of infants prevails in almost every province of the Republic. It is the girl babies that are the victims of this practice.[187] They are often drowned or buried alive. In this practice the subsistence motive of course is active. It is in general the extreme poverty of the people which causes them thus to destroy their offspring. But what renders this practice significant for the student of morality is the fact that these things are done with little or no scruple of conscience,[188] showing that acts respecting which the conscience of Christian nations has become very sensitive have not yet among the Chinese been brought generally within the circle covered by the moral feelings.
