But, as we all know, in the long run the experiment broke down. The Jews were readmitted in the middle of the seventeenth century, and nowhere have they come to greater strength than in the very nation which attempted this solution of the problem with such drastic thoroughness five hundred years ago. None of the other parallel attempts up and down Europe were of the same thoroughness as the English attempt. Their failure came, therefore, more quickly. But such failure would seem in any case to be inevitable. Quite apart, therefore, from the moral objection which attaches to it, there is the practical experience that a solution is not to be found upon such lines.

Lastly, there is elimination by absorption. This would obviously be the most gentle, as it is the most evident, of all methods. It is further a normal and most usual method of nature herself when a living organism has to deal with disturbance excited by the presence of an alien body. So natural and so obvious is it that it has been taken by many men of excellent judgment upon both sides as a matter of course. It has been taken for granted that if absorption has not taken place in the past it has only been due to an ill-will artificially nourished and maintained against the Jews on our side, or by the unreasoning exclusiveness of the Jews on theirs.

Even to-day, in spite of a vast increase during our own generation, both in the public appreciation of the problem and in its immediate gravity, there are very many men who still regard absorption as the natural end of the affair. These, though dwindling, are still numerous upon the non-Jewish side; upon the other, the Jewish side, they are, I think, a very small body. For I note that even those Jews who think absorption will come, admit it with regret, and certainly the vast majority would insist with pride upon the certain survival of Israel.

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.

The thing might have come where there was a chaos of peoples, as in pagan Alexandria in the four centuries from 200 B.C. to 200 A.D., or in modern New York. It might have come where there was a particularly friendly attitude, as in mediaeval Poland or modern England. It might even have come, paradoxically, through the very persecution and strain of times and places where the Jews suffered the most hostile treatment: for their absorption might have been achieved under pressure though it had failed to be achieved under attraction. As a fact it has never come. It has never proved possible. The continuous absorption of outlying fractions, a process continually going on wherever the Jewish nation is present, has not affected the mass of the problem at all. The body as a whole has remained separate, differentiated, with a strong identity of its own under all conditions and in all places, and the a priori reasoning, by which men come to think this solution reasonable, is nullified by an experience apparent throughout history. That experience is wholly against any such solution. It cannot be.

There remains, then, only the solution of segregation; a word which (I repeat) I use in a completely neutral manner though it has unhappily obtained in this and other issues a bad connotation.

Segregation, as I have said, may be of two kinds. It may be hostile, a sort of static expulsion: a putting aside of the alien body without regard to that body's needs, desires or claims; the building of a fence round it, as it were, solely with the object of defending the organism which reacts against invasion, and suffers from the presence within it of something different from itself.

Or it may take an amicable form and may be a mutual arrangement: a recognition, with mutual advantage, of a reality which is unavoidable by either party.
