For the philosopher and psychologist this book offers the first thoroughly cross-disciplinary interpretation of Jung’s psychology. Using the conceptual framework of traditional Western philosophy, Nagy studies the internal structure of Jung’s theory. His epistemology, his ontology (archetypes), and his teleological views (individuation and theory of self) are analyzed in the context of late nineteenth and early twentieth century philosophical and scientific problems. Jung’s psychology is a response to the challenge of Freud and to the rise of the empirical sciences.
