Abstract

The text examines the attempt by Jürgen Habermas to renew the tasks of critical theory. The systematic reconstruction of his writings reveals a system of typical functions: a) the rationalization of instrumental and strategic action in the material reproduction of social systems (social technology); b) the analysis of the pathologies in the symbolic reproduction of the world of life; c) the clarification of the cognitive, value and expressive models in the public sphere; d) the unveiling of false representations that dominate the mainstream (critique of ideology); e) sketching out alternatives to the status quo, through the utopia of a non-reified communicative everyday practice. All these functions actualize the Enlightenment project to place the cultural tradition in the service of civil and social progress. This ambitious program, however, must recognize the limitations of critical theory, with respect to the need for consolation and hope of human existence. The dialogue between philosophy and religion, which marks the last decade of Habermas's reflection, should be understood in this light.
