The field of special education as an integrative human science, as a practice of developmental support and promotion of participation, is broad and diverse. It encompasses the development of foundations and methods, the self-understanding, and the societal role of special educational actions. This volume brings together a wealth of contributions from various themes and fields of special education: practical suggestions, explorations of the history of special education, community building, and inclusion - in the dialogue between theory and practice and from different perspectives, including those of anthroposophical special education and social therapy. 23 authors provide reports of experience and thought-provoking insights for this festschrift dedicated to Rüdiger Grimm.
