The dissertation studies the relationship between Québécois and Indigenous peoples with regards to two different approaches to self-determination. It offers a critique of sovereignty-based self-determination in the form of the nation-state – a hegemonic model throughout the world and within Québécois political imagination – by shining light on the co-constitutive relationship between vulnerability and sovereignty, tracing the origins of their conceptual association in the work of Hobbes. The dissertation argues that, comparatively, by asserting the priority of relationality over individuality, the work of Marcel Mauss contributes to a relational theory of self-determination. By positing togetherness, relationality, reciprocity, and difference as forming the most basic reality of politics, Maussian gifting offers new perspectives on the question of vulnerability in the context of intercultural relations. Finally, through a study of the ethos of Indigenous treaty philosophy, the dissertation argues for re-envisioning Québécois self-determination through the role of treaty partner and honouring the gift of hospitality contained in the early treaties and alliances of peace and friendship with Indigenous peoples. / Graduate / 2020-04-18
