The answers to these questions have already been suggested in the preceding paragraphs, in regard to what has already taken place in Japan. But we may add that that answer really turns on our conception as to the nature of the characteristics separating the East from the West. In proportion as national character is reckoned to be biological, will it be considered fixed and the national destiny predetermined. In proportion as it is reckoned to be sociological, will it be considered alterable and the national destiny subject to new social forces. Now that the intercourse of widely different races has begun on a scale never before witnessed, it is highly important for us to know its probable consequences. For this we need to gain a clear idea of the nature both of the individual man and of society, of the relation of the social order to individual and to race character, and of the law regulating and the forces producing social evolution. Only thus can we forecast the probable course and consequences of the free social intercourse of widely divergent races. It is the belief of the writer that few countries afford so clear an illustration of the principles involved in social evolution as Japan. Her development has been so rapid and so recent that some principles have become manifest that otherwise might easily have escaped notice. The importance of understanding Japan, because of the light her recent transformations throw on the subject of social evolution and of national character and also because of the conspicuous rôle to which she is destined as the natural leader of the Oriental races in their adoption of Occidental modes of life and thought, justifies a careful study of Japanese character. He who really understands Japan, has gained the magic key for unlocking the social mysteries of China and the entire East. But the Japanese people, with their institutions and their various characteristics, merit careful study also for their own sakes. For the Japanese constitute an exceedingly interesting and even a unique branch of the human race. Japan is neither a purgatory, as some would have it, nor a paradise, as others maintain, but a land full of individuals in an interesting stage of social evolution.
