Abstract

Deliberative democrats have abandoned the ideal of consensus in favour of a range of different, more realistic alternatives. But these alternatives provide little anchorage to guide or even evaluate deliberative practice – something acutely problematic given the contemporary context of accelerating polarization in many advanced liberal democracies. In this article, we turn to Stalnaker’s account of the ‘common ground’ – the shared pool of information that is agreed upon by the parties to a discourse – to reassert a distinct ideal standard for democratic deliberation which remains malleable enough to apply across messy contexts of real-world political contestation and debate. Our account offers an appropriate normative yardstick by which to assess deliberative practices across different discursive contexts, as well as impetus for further experimentation and innovation in efforts towards democratic renewal and reform.
