Abstract
Despite being a staple of liberal-democratic politicians’ and theorists’ rhetorical arsenal, ‘openness’ as a political commitment has yet to receive sustained philosophical analysis. My aim in this paper is to provide such an analysis. I will argue that political openness involves a readiness by an agent to engage with others forthrightly and receptively, and to recognise their authoritative standing in political domains. I demonstrate the explanatory value of this account by showing that it provides an insightful explanation of what’s at stake in the emerging political cleavage between ‘open’ and ‘closed’ politics, explains the appeal of ‘the open society’ as an epithet for liberal democracies, and provides a compelling interpretation of openness’ contribution to social dynamism and progressive reform, one which diverges favourably from the emphasis others have put on social experimentation and trial and error learning.
