In addressing the political and theoretical debates between critical and post-Marxist theorists, this book discusses the politics of communication and rationality, subjectivity, sovereignty, ethics and deliberative democracy, considering questions such as: * Does the theory of communicative action justify deliberative democracy? * Is a theory of hegemony compatible with an account which relies upon an ideal of communicative success? * Is autonomy a good which should be fostered? * Can the ideal of democracy extend beyond the nation state? * Does post-Marxism have anything interesting to say about ethics? Analysing the work of Ernesto Laclau and Jürgen Habermas - as representatives of different choices made in regard to theory, politics and morality - Ethics and Politics in Contemporary Theory develops a critical response to the contrasting conclusions of these approaches.
