In the final volume of his history of philosophy, Jürgen Habermas offers a series of brilliant interpretations of the thinkers who set the agenda for contemporary philosophy.  Beginning with masterful readings of Hume and Kant, he traces the genealogy of their postmetaphysical thinking through the main currents of historicism and German Idealism, and the multifarious reactions to Hegel's influential system, culminating in nuanced readings of Marx, Kierkegaard and Peirce.  Through his analysis of their work, Habermas demonstrates the interpretive fecundity of the central themes of his philosophical enterprise - his pragmatist theory of meaning, his communicative theories of subjectivity and sociality, and his discursive theory of normativity in its moral, juridical and political manifestations. In contrast to the bland compendia of thinkers and positions generally presented in surveys of the history of philosophy, Habermas's thematically focused interpretations are destined to provoke controversy and stimulate dialogue. With this work one of the indisputably great thinkers of our time presents a powerful vindication of his conception of philosophy as an inherently discursive - and not merely analytical or speculative - enterprise.
