When Benjamin Disraeli spoke of the 'two nations' in Britain he was perfectly right, only the working classes were not exactly a nation. But the gap in behavioral standards and in outlook, and of course in standards of living, were enormous. And in course of time, at least in countries such as Britain, the working classes more or less adopted and have become assimilated to the standards of the so-called 'gentle' classes. That is assimilation.The working class has hardly been able to govern, but they are no longer outsiders in relation to the state as they were before.

Of course you can more easily recognise the outsiders because they have a different skin color. But let us take for instance the relationship between the White Anglo-Saxon Protestant majority in America and the negroes. What is important here is that the negroes were the descendants from slaves and were excluded from power, while the white majority kept them at bay, kept them down, kept them where they are. If the negroes in the future became assimilated and acquired equal power access, if there were a black president, then many of these things would change.

Perhaps one could appoint three or four professional people specially concerned with the task of bridge building between the majority and the minority. Bridge building of this kind requires an effort from both sides. It's no good if the majority alone do it. The question is whether there is any response, whether people on the other side of the river also wish to try to build a bridge.

The integration in Germany was made easier by the fact that I am probably of the third generation. So I have undergone a process of assimilation, of Jews into German society.I lived as a child in Germany, the feeling of being surrounded by people of whom the majority had very strong anti-Semitic sentiments. But there was one very odd thing in the whole milieu in which I lived: no one accepted the stigmatization. It is quite difficult. No one, my father for instance, would ever take it seriously. He would regard anti-Semites as people of no education.

The natives of England are closing their doors to relationships with Asians and Africans or, for that matter, Turks and Spaniards. While the Africans and Asians on their part are increasingly closing their doors too and resentment at both sides is increasing. This trend can be dangerous. It can lead, sooner or later, to violence - even in this country, which is traditionally an opponent of violence.

I have touched here on a problem that is masked if one speaks of racism. And that is the fact that the major differences between the established and outsiders group, which create tension and irritation, is not the form of the face or the skin color but the form of behavior: something learned. The form of behavior and feeling, of sentiment, is different in the immigrant groups from that of the established groups, and that may give rise to an enormous irritation.

The heart of assimilation process of absorbing minorities lies in the self-image of a nation. There are, as you will know, big differences for instance between the self-image of the French and the English. And the Germans, in accordance with their rather chequered history, had at least in the past very little capacity for absorbing minorities.
