's most important writings on society, the state, and social theory collected in one volume. For more than three decades Habermas has consistently attempted to supply foundations for a reconstructed Marxist social theory that provides a critical analysis of modernity. He has defended the position that only if a general notion of reason can be invoked can we hope to sustain a democratic social order. This carefully edited volume includes selections from Habermas's earliest works through his most recent: essays on the aim of social science, the structure of a theory of action and society, the development of modern society, psychoanalysis, and the crisis of the welfare state.
