The paper explores approaches to cultural diversity and its relation to the concept of social cohesion in the context of a multicultural school community. It uses insights from an empirical research on multicultural education conducted in Namibia as context for a discussion on tools in educational practice that would support diversity while working towards a greater integration of a pluralistic society. Looking into the African concept of Ubuntu and the corresponding teachings of the philosophers of dialogue, this theoretical paper suggests dialogic learning as an approach to multiculturalism that can enhance tolerance among peoples and produce a society united through understanding.
