The purpose of that dialog is not to rehearse old differences. Rather it is to find new points of growth and overlap, and to identify new and important theoretical and empirical topics. The book thus collects together studies which explore topical questions of general interest: corporeality and subjectivity; passion and desire; organizational and political struggle; economics; and cross–cultural contacts.
