This is a position paper tackling the topic of culture as a sociological concept, with the aim of retracing clues for interpreting the new multicultural shape of societies, that arises from de-construction processes and from the constant, mutable, dialectic inside\outside. Main argument is that, given that culture is created and taught, rather than being anything inherited, socialisation and its agencies are the vehicle for integration and re-construction, on the condition that the pluralism principle is equally recognised and respected by all players.
