Book excerpt: This collection of ten essays offers the first systematic assessment of JürgenHabermas's Philosophical Discourse of Modernity, a book that defended the rational potential of themodern age against the depiction of modernity as a spent epoch. The essays (of which four are newlycommissioned, five were published in the journal Praxis International, and one -- by Habermas --first appeared in translation in New Critique) are divided into two sections: Critical Rejoindersand Thematic Reformulations.An opening essay by d'Entrèves sets out the main issues and orients thedebate between Habermas and the postmodernists by identifying two different senses ofresponsibility: a responsibility to act versus a responsibility to otherness (an openness todifference, dissonance, and ambiguity). These are linked with two alternative understandings of theprimary function of language: action-orienting versus world-disclosing. This is a fruitful way oflooking at the issues that Habermas has raised in his attempt to resurrect and complete the projectof Enlightenment.Habermas's essay discusses the main themes of his book in the context of a criticalengagement with neoconservative cultural and political trends. The main body of essays offer aninteresting collection of points of view, for and against Habermas's position by philosophers,social scientists, intellectual historians, and literary critics.SECTIONS & CONTRIBUTORS :Introduction, Maurizio Passerin d'Entrèves.
