How did Karl Jaspers’s General Psychopathology influence existential approaches to psychiatry?

Karl Jaspers’s General Psychopathology (1913) was foundational in introducing existential perspectives into psychiatry by shifting the focus from purely causal, biological explanations toward a deeper understanding of the patient's subjective world.12

Influence on Existential Psychiatry

Jaspers integrated phenomenology—the direct investigation and description of phenomena as consciously experienced—into clinical practice. This approach emphasized the need for a "sympathetic participation" in the patient's experience to comprehend the world in which they live, rather than merely categorizing symptoms or focusing solely on mental illness as a biological defect.12

By prioritizing the individual's lived reality, Jaspers’s work paved the way for later existentialist developments in the field. For instance, the Swiss psychiatrist Ludwig Binswanger built upon these foundations by interpreting mental illness as a failure in the existential possibilities that constitute human existence (Dasein). Together, these contributions helped establish an existentialist current in contemporary psychiatry that values the individuality and nonrepeatability of human existence.2
