A new tendency to limit immigration and to seek some test of its quality has been a marked feature of the last quarter of a century. The principle is almost certainly sound; the right to act on it, to anyone who accepts the doctrine of national self-government, unquestionable. Whether the test ultimately imposed by a recent Act passed by Congress over President Wilson's veto, that of literacy, is a wise one, is another question. Its tendency may well be to exclude great masses of the peasantry of the Old World, men admirably fitted to develop by their industry the resources of America, whose children at least could easily be taught to read and write the American language and would probably become excellent American citizens. On the other hand, it does not exclude the criminal, or at any rate the most dangerous type of criminal. It does not exclude the submerged population of great European cities, the exploitation of whose cheap labour is a menace to the American workman's standard of life. And it does not, generally speaking, exclude the Jew. The problem of the Jew exists in America as elsewhere--perhaps more formidably than elsewhere. This, of course, is not because Jews, as such, are worse than other people: only idiots are Anti-Semites in that sense. It arises from the fact that America, more than any other nation, lives by its power of absorption, and the Jew has, ever since the Roman Empire, been found a singularly unabsorbable person. He has an intense nationalism of his own that transcends and indeed ignores frontiers, but to the nationalism of European peoples he is often consciously and almost always subconsciously hostile. In various ways he tends to act as a solvent of such nationalism. Cosmopolitan finance is one example of such a tendency. Another, more morally sympathetic but not much less dangerous to nationalism in such a country as America, is cosmopolitan revolutionary idealism. The Socialist and Anarchist movements of America, divided of course in philosophy, but much more akin in temper than in European countries, are almost wholly Jewish, both in origin and leadership. For this reason, since America's entrance into the Great War, these parties, in contrast to most of the European Socialist parties, have shown themselves violently anti-national and what we now call "Bolshevist."
