This article proposes a critical reading of pro-sovereignty discourse on the recomposition of Quebecois national public space. Essentially, it maintains that the redefinition of the nation desired by advocates of Quebec sovereignty, which pushes Quebec to the realization of a de-ethnicized nation, predicated on a civic, rational logic, is out of step with the Quebecois social imaginary and the political reality of Quebec. Cloaked in an adherence to universal reason, this redefinition essentially banishes ethnicity and cultural particularisms and advocates subsuming both the historical identity of the Quebecois and other identities now constitutive of Quebec's social fabric by an homogenizing, post-national public space. Contrary to appearances, the sense of the nation emanating from the pro-sovereignty theoretico-political project actually hides an act of exclusion and hegemonic aspirations for the historical nation. The author maintains that it is pointless to evacuate the difference and alterity inherent to the Quebec's political dynamic. Ethnicity and culture are unavoidable facts of conscience. A true avant-garde project for the recomposition of Quebec's public space should seek to accept its tenants and constitute a flexible institutional structure that does not dismiss alterity and difference, that does not establish a hierarchy of identities, and that is not based on a pre-established conception of the public space. This involves abandoning "Nation" as the axiomatic pivot of the political community and a fundamental re-examination of the parameters of contemporary liberalism.
