As a theory and practice of understanding, Theme-Centered Interaction (TCI) can contribute to shaping our interpersonal, social and global coexistence in a manner that is humane and based on solidarity. This volume takes up the critical potential of topic-centered interaction and brings it up for discussion - both in social and in scientific discourses. Eight authors illuminate educational, sociological, philosophical, ethical, political and linguistic perspectives on a wide variety of topics such as anti-discriminatory language use, sustainability and critical consumption.
