In this article, I examine the role of cities in the accomodation of ethnocultural diversity. I study the idea that there is a certain heuristic function in taking into consideration the specificities of the urban context and the geographic dimensions of the city. Such consideration leads us (1) to revise our understanding of the agents called upon to honour a conception of justice; (2) to take a second look at the agenda of normative political philosophy while shedding light on the questions and issues specific to this context; and, finally, (3) to discern certain political possibilities and strategies aiming to promote justice and the common good. More specifically, paying attention to the context of the city within a reflection on multiculturalism promises to enrich our understanding of the public policies likely to promote or to jeopardize integration and social cohesion in pluralist societies. Thus, the ideal of the intercultural city offers to make the fostering of intercultural interactions in urban spaces one of the pillars of urban planning.
