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.

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.

Scientific modes of thought cannot be developed and become generally accepted unless people renounce their primary, unreflecting, and spontaneous attempt to understand all their experience in terms of its purpose and meaning for themselves. The development that led to more adequate knowledge and increasing control of nature was therefore, considered from one aspect, also a development toward greater self-control by men.

I wish you all the pleasurable excitement one can have without hurting others and one's own dignity.

Debating the concept of race does not mean that I in any way regard this as a quarrel between neighbors over where they come from. I have perhaps said enough when I said the alternative to assimilation is that immigrant groups form their own state or go away for lack of acceptance. Why should it be less serious if quarrels and dissensions are socially related? After all, the quarrels and dissensions between Russia and America are also not racial. And yet they seem to me extremely dangerous.

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.
