That sort of love does not have a boundary-line of hate

How does one hate a country, or love one? [...] I know people, I know towns, farms, hills and rivers and rocks, I know how the sun at sunset in autumn falls on the side of a certain lowland in the hills; but what is the sense of giving a boundary to all that, of giving it a name and ceasing to love where the name ceases to apply? What is love of one's country; is it hate of one's uncountry? Then it's not a good thing. Is it simply self-love? That's a good thing, but one mustn't make a virtue of it, or a profession... Insofar as I love life, I love the hills of the Domain of Estre, but that sort of love does not have a boundary-line of hate. And beyond that, I am ignorant, I hope.

The thing that is so worrying about the character of the immigrant is the emigrant

Perhaps the reason why immigrants worry settled people so much (and often so abstractly) is that they expose the relative nature of certainties inscribed in the soil: the thing that is so worrying and fascinating about the character of the immigrant is the emigrant. The state of contemporary Europe certainly forces us to envisage the 'return' of nationalisms. Perhaps, though, we should pay more attention to the aspects of this 'return' that seem essentially to express rejection of the collective order: obviously the model of national identity is available to give form to this rejection, but it is the individual image (the image of the free individual course) that animates and gives meaning to the model today, and may weaken it tomorrow.

Borders do not acknowledge and register an already existing estrangement

As Frederick Barth explained, borders do not acknowledge and register the already existing estrangement; they are drawn, as a rule, before the estrangement is brought about. First there is a conflict, a desperate attempt to set 'us' apart from 'them'; then the traits keenly spied out among 'them' are taken to be the proof and the source of a strangehood that bears no conciliation. Human beings being as they are multi-faceted creatures having many attributes, it is not difficult to find such traits once the search has started in earnest.
