 In his classic essay “The phenomenological approach to psychopathology”, Karl Jaspers defended the irreducible reality of the “subjective” mental symptoms and stressed the pivotal role of empathy in their diagnostic assessment. However, Jaspers’ account of the epistemological role of empathy in psychopathological diagnosis was far from clear: whereas at several places Jaspers claimed that empathy provides a direct access to patients’ abnormal mental experiences, at other places he stressed that it did so only indirectly, through a whole battery of their observable clinical indicators. The aim of this paper is to reassess Jaspers’ account of the epistemological role of empathy in psychopathological diagnosis.
