But here again I maintain that we have the index of history against us. In point of fact absorption has not taken place. It has had a better chance than any corresponding case can show: ample time in which to work, wide dispersion, constant intermarriage, long periods of tolerant friendship for the Jew, and even at times his ascendancy. If ever there were conditions under which one might imagine that the larger body would absorb the smaller, they were those of Christendom acting intimately for centuries, in relation with Jewry. Nation after nation has absorbed larger, intensely hostile minorities: the Irish, their successive invaders; the British, the pirates of the fifth and eighth centuries and the French of three centuries more; the northern Gauls, their auxiliaries; the Italians, the Lombards; the Greeks, the Slav; the Dacian has absorbed even the Mongol: but the Jew has remained intact. However we explain this--mystically or in whatever other fashion--we cannot deny its truth. It is true of the Jews, and of the Jews alone, that they alone have maintained, whether through the special action of Providence or through some general biological or social law of which we are ignorant, an unfailing entity and an equally unfailing differentiation between themselves and the society through which they ceaselessly move. It is not true that conditions in the past differed from present conditions sufficiently to account for so strange a story. There have been generations and even centuries (not co-incident indeed throughout the world, but applying now to one country, now to another) where every opportunity for absorption existed; yet that absorption has never taken place. There was every chance in Spain at one moment, in Poland at another, but there was the best chance of all in the short but brilliant period of Liberal policy which has dominated Western Europe during the last three generations. That policy has had the fullest play: it has left the Jews not only unabsorbed, but more differentiated than ever, and the political problem they present more insistent by far than it was a century ago.
