This article compares Habermas’s and Taylor’s approach to the role of religious language in a liberal democracy. It shows that the difference in their approach is not simply in their theories of religious language. The contrast lies deeper, in their incompatible moral theories: Habermas’s universal discourse ethics vs Taylor’s communitarian substantive ethics. I also explore William Rehg’s defence of discourse ethics by conceding that it is based on a metavalue of rational consensus. However, I argue that Habermas’s and Rehg’s discourse (...) ethics and translation proviso are untenable. While Taylor rightly argues that there is no reason to exclude religious reason from the formal political sphere, his proposed fusion of horizons to generate a new hybrid framework is also problematic. I suggest that Taylor’s historical hermeneutics should be extended to include the narrative approach to ethical deliberation as conducive to mutual experiential understanding, and hence to achieving a fusion of horizons of the diverse worlds of citizens in a liberal democracy.
