Popper dismisses Jaspers ¡®existentialism¡¯ as nihilistic and historicist; Jaspers never cites Popper. Jaspers describes Kant as ¡®the philosopher for me¡¯; Popper is an unorthodox Kantian whose critical rationalism put the finishing touch to Kant. For Kant, knowledge is not a simple copy of reality, but begins with reason¡¯s questioning. Jaspers and Popper too insist that theory has priority over observation. For Jaspers, ¡®there is already theory in every fact¡¯; for Popper, ¡®every statement has the character of a theory¡¯. Science begins with metaphysical Ideas which become scientific when tested in experience. They differ in Popper¡¯s rejection of induction in favour of falsification, while Jaspers tacitly accepts induction %K Jaspers %K Kant %K legacy %K Popper %K psychopathology %K theory and existentialism %U https://journals.sagepub.com/doi/full/10.1177/0957154X19826473
