Contributed by leading scholars of Quebec Studies, both emerging and established, the 30 essays of this comprehensive collection offer a multidisciplinary survey of the study of diversity in Quebec over space and time. The volume is organized around a variety of themes through which Quebec’s plural reality is expressed, including conceptual, historical and contemporary approaches, covering a wide range of social and economic cleavages, identity markers, political contestation and, broadly, the lived experiences of Quebecers negotiating difference over time. In an environment increasingly demarcated by conflicts around values and cultural and social practices, this collection hopes to contribute to broadening the spectrum of voices to the current debate, adding an inclusive reflection to a conversation that has only intensified over the last decade. Quebec as a pluri-national and multi-ethnic society has been and remains a great laboratory to study and to test public policies on ethnic diversity. It allows us to identify the tensions and to evaluate the balance between the majority and the minority; and between settler society and indigenous nations, in conceptualizing and finding a normative consensus around the configuration of collective rights. In short, the contributions in this volume seek to illustrate how pluralism has and continues to constitute the lifeblood of belonging in Quebec.
