The major cause of the agitation against Japanese in California must be attributed to modern civilization, which, with scientific devices, has conquered time and space and thereby destroyed the high walls of international boundaries. Indeed, had it not been for the steamboat, railroad, telegraph, and other civilized instruments, which bind the nations of the world into a composite whole, and modern industrialism, which civilization brought about and which in turn assisted in unifying the world, Japan for one would have remained a peaceful hermit nation, undisliked or unsuspected by any other. She, of course, has no reason to regret the adoption of European culture, which brought her untold values and happiness; but the fact remains that the present anti-Japanese agitation in California, as well as elsewhere in the world, would never have occurred had she not followed the lead of Occidental nations. Clearly, such a conflict is one of the by-products of the complex international relations brought about by modern science, which, simply because of the lack of experience and regulation due to their short history, remain deplorably defective. This suggests the point already brought out in our introduction, that the principle of the solution of the California problem lies not in an attempt at separating Japan and the United States, which time and destiny brought together, but in a yet closer, more regulated relationship, and in the promotion of a better mutual understanding. Various Attitudes Towards Japanese. With reference to the attitude toward the Japanese, it is possible to discern four classes of critics in California. There are the veteran exclusionists, whose only hope in this world seems to be the realization of the slogan, "All Japs must go!" There is the majority of people which is too preoccupied with its own affairs to investigate the facts and is ready to accept anything said or asserted by the exclusionists. Then there are those, intellectually more critical, who hold independent opinions as to why the Japanese must be excluded. There are also others who stoutly oppose, rationally or irrationally, any attempt at excluding the Japanese.
