2013 sees the centenary of Jaspers' foundation of psychopathology as a science in its own right. The general sense of the General Psychopathology and its specific contribution are discussed. In particular, the lecture focuses on three major contributions: the methodological import (Jaspers perspectivism), the importance to study subjective experiences scientifically (Jaspers' phenomenology), and the concept of understanding. Three psychiatrists with partly different theoretical background discuss with the members of the Roman Circle of Psychopathology questions like: the specific historical and theoretical (...) features of early Twentieth Century culture, science and psychiatry in Germany; Jaspers' relationship with other great thinkers of his time (Freud, Husserl, Heidegger, Kretschmer); the reception of the General Psychopathology in different countries; and the importance and limitations of Jaspers' approach for nowadays psychopathology.
