The history of humanity is a history of exiles. For Jews and Christians, the exile from Paradise is the beginning of history. For Muslims, it is the exile from Mecca. For political dissidents throughout the world, it is a miserable refrain, one of one the principle forms of "reeducation", punishment or simply annihilation. Millions of human beings have been led violently, by force or voluntarily into exile for political, religious or national reasons or simply in search of a better life. Exile is a state of the bidy, but also a state of mind. It is inscribed in our DNA, we carry within ourselves the nostalgia for an ideal topos, a utopia, even if our daily lives take the form of "normality". In our days, its real and symbolic aspects are more real than ever.
