Habermas, Lyotard and the Concept of Justice

Book excerpt: Habermas' recent work makes a major claim: to be able to determine what is the most rational thing to do. Postmodernists, notably Lyotard, have perhaps successfully belittled this claim as too positivistic. This book does not dispute the validity of the postmodern critique but it is concerned to resist the irrationality which, thus far, seems to coincide with anti-positivism. The author looks at the concept of justice, as one that is both essential to Habermas and Lyotard but is also utilized in their work only in constricted and unimaginative ways.
