This paper presents the main contents of Geiger’s 1910 lecture on empathy and focuses on its possible influence on Jaspers’ General Psychopathology. In particular, some key methodological distinctions traced by Jaspers are compared to Geiger’s similar concepts. Geiger’s role in shaping Jaspers’ concept of understanding is still neglected and it is time to recognize it. In particular, Geiger’s distinction between the direct empathy for the other’s expressions at one side, and the ‘reliving after the event’ of the ‘inner correlation of (...) the psyche’ on the other side had a major role in shaping Jaspers’ similar distinction between static and genetic understanding.
