This collection reflects recent discussions on the relation between identity and difference in metaphysics, and in moral and political theory in both the analytic and continental traditions. The contributions to the volume tackle such issues as the role and place of the concept of identity in Hegel's Science of Logic; the question of personal identity in Parfit, Riceour and Schechtman; the problem of inclusion and exclusion in Heidegger's reading of the history of philosophy; Heidegger's conception of the relation between philosophy and politics, the question of alterity in Levinas; and Foucault's conception of the relation between sexual instinct, economic interest, and desire. This book was originally published as a special issue of the Journal of the British Society for Phenomenology.
