(13) Aim at not being beaten in your competition with foreigners. Remember that loyalty and filial piety are our most precious national treasures and do nothing to violate them. Many of the above rules are excellent in tone. Number 7, however, which hails from Osaka, is somewhat narrow and prejudiced. The injunction not to sell houses to foreigners is, as the _Jiji Shimpo_ points out, absurd and mischievous.[H] The sensitiveness of the people also works to the advantage of the nation in the social unity which it helps to secure. Indeed I cannot escape the conviction that the striking unity of the Japanese is largely due to this characteristic. It tends to make their mental and emotional activities synchronous. It retards reform for a season, to be sure, but later it accelerates it. It makes it difficult for individuals to break away from their surroundings and start out on new lines. It leads to a general progress while it tends to hinder individual progress. It tends to draw back into the general current of national life those individuals who, under exceptional conditions, may have succeeded in breaking away from it for a season. This, I think, is one of the factors of no little power at work among the Christian churches in Japan. It is one, too, that the Japanese themselves little perceive; so far as I have observed, foreigners likewise fail to realize its force. Closely connected with this sensitiveness to environment are other qualities which make it effective. They are: great flexibility, adjustability, agility (both mental and physical), and the powers of keen attention to details and of exact imitation. As opposed to all this is the Chinese lack of flexibility. Contrast a Chinaman and a Japanese after each has been in America a year. The one to all appearances is an American; his hat, his clothing, his manner, seem so like those of an American that were it not for his small size, Mongolian type of face, and defective English, he could easily be mistaken for one. How different is it with the Chinaman! He retains his curious cue with a tenacity that is as intense as it is characteristic. His hat is the conventional one adopted by all Chinese immigrants. His clothing likewise, though far from Chinese, is nevertheless entirely un-American. He makes no effort to conform to his surroundings. He seems to glory in his separateness. The Japanese desire to conform to the customs and appearances of those about him is due to what I have called sensitiveness; his success is due to the flexibility of his mental constitution.
