In this important book, Jurgen Habermas takes up certain fundamental questions of philosophy. While much of his recent work has been concerned with issues of morality and law, in this new work Habermas returns to the traditional philosophical questions of truth, objectivity and reality which were at the centre of his earlier classic book Knowledge and Human Interests. In this new work Habermas returns to the traditional philosophical questions of truth, objectivity and reality. Habermas pursues these questions from the perspective of his own formal pragmatic theory which is based on an analysis of speech acts and language use. He asks: How can the idea that our world exists independently of our attempts to describe it be reconciled with the insight that we can never reach reality without the mediation of language? Addresses the limits of philosophy and reassesses the relation between theory and practice from a 'post-Marxist' perspective.

Jurgen Habermas is Emeritus Professor of Philosophy at the University of Frankfurt.
