“One or Many Ontologies? Badiou’s Arguments for His Thesis ‘Mathematics is Ontology’”

This article explores rival interpretations of Badiou’s strategy behind the claim ‘mathematics is ontology’, from his construction of an alternative history of being to that of Heidegger to his exposure of the radical contingency of the ‘decisions on being’ carried out by transformative practices in the four conditions of philosophy: art, politics, love and science. The goal of this exploration is to open up the possibility of another strategy that responds to Badiou’s initial intuition – that being is multiple – by embracing the writing of multiple ontologies in the sphere of action.
