Commonly defined as the acceptance and even endorsement of cultural diversity, multiculturalism seems to echo Bakhtin's notion of heteroglossia, a polyphonic dialogue between texts, voices and discourses, where hierarchies are constantly undermined by the free play of centres and margins. Today, multiculturalism has become an effigy of the contemporary society and discourse, but although it is generally perceived as a positive outcome of cultural progress, it also poses some ethical problems related to cultural assimilation and erasure of boundaries. Our conference aims to host discussions on the ways in which the contemporary discourse mirrors this symptomatic crossing of linguistic, cultural and narrative boundaries, in order to achieve an accurate radiography of multiculturalism in all its aspects.
