In this article I confront Jürgen Habermas' deliberative model of democracy with Claude Lefort's analysis of democracy as a regime in which the locus of power remains an empty place. This confrontation reveals several structural similarities between the two authors and explains how the proceduralization of popular sovereignty provides a discourse-theoretical interpretation of the empty place of power. At the same time, Lefort's insistence on the open-ended nature of the democratic struggle also points towards an unresolved tension at the core (...) of Habermas' model between the cognitive nature of deliberation on the one hand and the freedom of moral and political agents on the other. A proper solution of this tension requires a full appreciation of the ineliminable gap between actual and ideal deliberation. Because actual deliberation can never result in an ideal consensus, the actual exercise of democratic power should be understood as an unavoidable interruption of deliberation. Key Words: consensus • deliberation • democracy • empty place of power • Jürgen Habermas • Claude Lefort. (shrink)
