[Unexplored themes in the psychopathology of Karl Jaspers]

This study discusses: (1) the impact of the methodological approach to psychopathology of K. Jaspers and its potential for further development; (2) the possibility of developing phenomenological sight to participating insight (into the inner experiences of patients) as a preliminary form of therapy; (3) Jaspers' discrimination between the "understandable" and the "non-understandable" as a problem of communication (strictly differentiating between common sense communication and psychotherapeutic understanding and communicating); (4) the considerable relationship between existential communication ("Existenzerhellung") or maieutic procedure and psychotherapy. The bibliography contains 151 references.
