Changes and hybridization have nourished all civilizations, but today, demanded by false desires and imagination, how can one think of this problem without there being any imposture or alienation ? Certain modes that have been introduced as « intercultural crossbreeds » are rather annoying. The dogmatic enclosure of identity, also between these two extremes, creativity, vision compared to universal phenomenon, real needs of life, necessary to establish bonds with the « other », help us to foresee the way.Faced with a global period of « Bio,power » (Foucault) we other Mediterraneans are called on to unite (miscere consilia) faced with a North, North project which sacrifices us in the name of geo,politics. This project makes us doubt the word « crossbreeding », the term being somewhat disreputable ; It makes us also doubt World Culture such as we are fed by the media and intervening markets. But we know that crossbreeding is a historical and spatial constancy, a means of exchange and mutation, a melting pot of new creations, thoughts and forms, a benificial confrontation, on condition that there is not a « blind identity » (Khatibi) imposed by both sides.
