The cornerstone of Jaspers’ work is the distinction between causal explanation and meaningful understanding. Natural sciences, including neurobiology, seek explanation by identifying external causes and law-like regularities (e.g., a brain tumor causing memory loss). In contrast, Jaspers argued that the core of psychopathology—delusions, hallucinations, phobias, and personality changes—requires understanding of the psychic connections that are meaningful to the patient. A patient’s jealous delusion, for example, cannot be causally deduced from a neurotransmitter imbalance alone; the clinician must understand its emergence from a life-history context, a sense of betrayal, or a transformation of meaning. This distinction prevents two errors: treating all mental phenomena as if they were purely physical symptoms, and naively believing that all psychic events are transparently rational. For Jaspers, the limit of understanding is precisely where genuine psychopathology begins—in the “ununderstandable” primary delusions or radical personality shifts that break the chains of meaningful biography.
Here, Jaspers explores how life events connect to mental states. For example, how shame leads to depression, or how trauma reshapes personality. This section is the foundation of modern psychodynamic and existential therapy. karl jaspers psicopatologia general pdf
