powerful outside pressure which, even more than its precepts, has everywhere constituted of the Jews a community within a community. Thus has been built up and maintained a certain peculiar environment which gives a distinctive character. Jewish intermarriage has been the effect, not the cause of this. What persecution which stopped short of taking Jewish children from their parents and bringing them up outside of this peculiar environment could not accomplish, will be accomplished by the lessening intensity of religious belief, as is already evident in the United States, where the distinction between Jew and Gentile is fast disappearing.
And it seems to me that the influence of this social net or environment will explain what is so often taken as proof of race differences—the difficulty which less civilized races show in receiving higher civilization, and the manner in which some of them melt away before it. Just as one social environment persists, so does it render it difficult or impossible for those subject to it to accept another.
The Chinese character is fixed if that of any people is. Yet the Chinese in California acquire American modes of working, trading, the use of machinery, etc., with such facility as to prove that they have no lack of flexibility, or natural capacity. That they do not change in other respects is due to the Chinese environment that still persists and still surrounds them. Coming from China, they look forward to return to China, and live while here in a little China of their own, just as the Englishmen in India maintain a little England. It is not merely that we naturally seek association with those who share our peculiarities, and that thus language, religion and custom tend to persist where individuals are not absolutely isolated; but that these differences provoke an external pressure, which compels such association.
