Influenced principally by Heidegger, Lacan, and Laclau and Mouffe, but also drawing on Foucault, Wittgenstein, and Derrida, we put forward an ‘ontology of lack’, which is a negative ontology premised on the radical contingency of social relations. Stated simply, we take this axiom to imply that any system or structure of social relations is constitutively incomplete or lacking for a subject. … every social identity is always-already dislocated. On the one hand we take this to be a strictly ontological understanding of dislocation, in which each and every symbolic order is penetrated by an impossibility that has to be filled or covered-over for it to constitute itself. The category of dislocation can also be understood, however, in more ontical terms: moments in which the subject’s mode of being is disrupted by an experience that cannot be symbolized within and by the pre-existing means of discursive representation. From this perspective, practices are governed by a dialectic defined by incomplete structures on the one hand, and the collective acts of subjective identification that sustain or change those incomplete structures on the other.
