This volume attempts to renew and reinvigorate critical theory by extending its range and its intellectual trajectories through strategies of inclusiveness that respect and build on parallel traditions. The authors reinterpret the work of Nietzsche, Wittgenstein and Heidegger in relation to central figures (Kant, Marcuse, Foucault) and themes of critical theory - the critique of modernity, theory of the self and the question concerning technology.
