The German philosopher Jürgen Habermas has long been recognized as the most persistent and influential defender of an Enlightenment rationality that has been attacked both by postmodernism, which derides formal reason’s claims of internal coherence and neutrality, and by various fundamentalisms, which subordinate reason to religious imperatives that sweep everything before them, often not stopping at violence. In his earlier work, Habermas believed, as many did, that the ambition of religion to provide a foundation of social cohesion and normative guidance could now, in the Modern Age, be fulfilled by the full development of human rational capacities harnessed to a “discourse ethics” that admitted into the conversation only propositions vying for the status of “better reasons,” with “better” being determined by a free and open process rather than by presupposed ideological or religious commitments: “…the authority of the holy,” he once declared, “is gradually replaced by the authority of an achieved consensus.”
