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 Jurgen 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.
