Since its beginnings, phenomenology has established itself as one of the most influential philosophical currents of the twentieth and twenty-first centuries. This handbook - the first of its kind in German - provides a comprehensive overview of the basic concepts, positions, developments, and fields of application. Tracing the non-linear development of the phenomenological movement in its historical and systematic breadth and diversity along methodologically justified turns, its specially written articles by distinguished authors present complex factual contexts clearly and succinctly. As an aid to independent exploration of the phenomenological school of thought and its application to topical issues, the volume is characterised by reader-friendliness and a strong practical reference to research, while its didactic structure ensures that it is an ideal tool for beginners and advanced students alike.
