Philosophy and psychiatry share many topics and problems. For example, the "solutions" of the psychiatry of the philosophical body-soul problem have direct effects on the self-image of the discipline. Despite these obvious overlappings, and unlike the English-speaking countries, interdisciplinary research on "philosophical psychopathology" has been scarce in Germany. The current anthology closes these gaps, because the authors - renowned experts as well as young scientists, whose new approaches open promising perspectives - come from both disciplines. The individual contributions deal with philosophical debates as they arise within the context of psychiatric theory and practice.
