The tragedy enacted in China during the closing year of the nineteenth century marks an epoch in the history of China and of the world. Two world-views, two types of civilization met in deadly conflict, and the inherent weakness of isolated, belated, superstitious and corrupt paganism was revealed. Moreover, during this, Chinas crisis, Japan for the first time stepped out upon the worlds stage of political and military activity. She was recognized as a civilized nation, worthy to share with the great nations of the earth the responsibility of ruling the lawless and backward races. The correctness of any interpretation as to the significance of this conflict between the opposing civilizations turns, ultimately, on the question as to what is the real nature of man and of society. If it be true, as maintained by Prof. Le Bon and his school, that the mental and moral character of a people is as fixed as its physiological characteristics, then the conflict in China is at bottom a conflict of races, not of civilizations. The inadequacy of the physiological theory of national character may be seen almost at a glance by a look at Japan. Were an Oriental necessarily and unchangeably Oriental, it would have been impossible for Japan to have come into such close and sympathetic touch with the West. The conflict of the East with the West, however, is not an inherent and unending conflict, because it is not racial, but civilizational. It is a conflict of world-views and systems of thought and life. It is a conflict of heathen and Christian civilizations. And the conflict will come to an end as soon as, and in proportion as, China awakes from her blindness and begins to build her national temple on the bedrock of universal truth and righteousness. The conflict is practically over in Japan because she has done this. In loyally accepting science, popular education, and the rights of every individual to equal protection by the government, Japan has accepted the fundamental conceptions of civilization held in the West, and has thus become an integral part of Christendom, a fact of world-wide significance. It proves that the most important differences now separating the great races of men are civilizational, not physiological. It also proves that European, American, and Oriental peoples may be possessed by the same great ideals of life and principles of action, enabling them to co-operate as nations in great movements to their mutual advantage. While even we of the West may be long in learning the full significance of what has been and still is taking place in Japan and more conspicuously just now, because more tragically, in China, one thing is clear: steam and electricity have abolished forever the old isolation of the nations. Separated branches of the human race that for thousands of years have been undergoing divergent evolution, producing radically different languages, customs, civilizations, systems of thought and world-views, and have resulted even in marked physiological and psychological differences, are now being brought into close contact and inevitable conflict. But at bottom it is a conflict of ideas, not of races. The age of isolation and divergent evolution is passing away, and that of international association and convergent social evolution has begun. Those races and nations that refuse to recognize the new social order, and oppose the cosmic process and its forces, will surely be pushed to the wall and cease to exist as independent nations, just as, in ancient times, the tribes that refused to unite with neighboring tribes were finally subjugated by those that did so unite.
