Jiirgen Habermas is a radical democrat. The source of that self-designation is that his conception of democracy-what he calls "discursive democracy"-is founded on the ideal of "a self-organizing community of free and equal citizens," co- ordinating their collective affairs through their common reason. The author discusses three large challenges to this radical-democratic ideal of collective self-regulation: 1) What is the role of private autonomy in a radical-democratic view? 2) What role does reason play in collective self-regulation? 3) What relevance might (...) a radical- democratic outlook have for contemporary democracies? The author addresses these questions by considering Habermas' answers, and then presenting alternative responses to them. The alternatives are also radical-democratic in inspiration, but they draw on a richer set of normative-political ideas than Habermas wants to rely on, and are more ambitious in their hopes for democratic practice.
