Published in 1913, General Psychopathology blends philosophy, rigorous conceptual analysis and detailed clinical examples. Jaspers makes the case that psychopathology requires two different methods (explaining and understanding) to address the predicament of the subjective nature of experience and what it was to be human. Key contributions from General Psychopathology to psychiatry include the conceptual framework for delusions, the issue of somatic prejudice, empathy as the key tool at our disposal in thinking about another person’s subjectivity, and the whole versus the part (gestalt). Jaspers was a proponent of the existential school of philosophy, which is evident throughout the work.
