Arjun Appadurai in Eurozine:
Forced exits can be created by traumas of environment, economy or national civil war. They produce refugees who are invariably traumatized. Their claims on the hospitality of the nations in which they land are always in a grey zone between hospitality, sanctuary and incarceration, because they are usually in a categorical grey zone that combines features of the stranger, the victim, the criminal and the undocumented visitor.
The trauma of the forced refugee provokes the deepest anxieties of the modern nation-state, which relies on boundaries, censuses, taxes and documentation. The heart of the new traumas that the forced refugee experiences in the new country is that he or she has a plot (a narrative, a story) but no character, identity or name. The challenge of evolving a new form of legal and ethical hospitality is to create a name to fit the plot, an identity to fit the narrative. The challenge of the modern nation-state is that, whereas its key narratives of identity rely on fixed starting points (blood, language, religion, territory), the forced exit is usually produced precisely by originary traumas of blood, language, religion or location. This raises the question of how to build a new relationship between plot and character in modern nation-states and a world of forced exits, where there is as yet no ethical foundation for seeing traumatic movement as the pivot of a serious identity for some citizens.
