Rancière’s political thought is the object of growing fascination, particularly as a lens through which to interpret contemporary political protests, yet his conception of axiomatic equality remains unexamined. This article investigates Rancière’s account of equality as a ‘presupposition’, showing that an axiom of equality guides momentary acts of resistance, but also serves as a ‘necessary and sufficient condition’ of all societies, however hierarchical. Although this account holds some appeal, I argue that it restricts equality to two, not especially satisfying possibilities: (...) a temporary revelation or a hidden secret. This rendering of axiomatic equality is symptomatic of Rancière’s general hostility toward institutional politics. Because Rancière tends to depict ‘institutions’ per se as oppressive, equality is positioned ‘outside’ the socio-political order – as its fleeting interruption or disavowed condition of possibility. I argue, on the contrary, that a radically egalitarian politics today should affirm a practice-centered project of institution-building. (shrink)
