This paper explores the epistemological sources of C.G. Jung's psychology over the course of its historical evolution. It considers whether his model should be seen as a scientific-philosophical, artistic, or an ethical-mystical model, or a combination of these; whether epistemological knowledge can come from getting a ‘vision of the whole’ or ‘grasping the particulars thoroughly’ (Jung 1939, para. 1012); as well as exploring the philosophers of science with whom Jung's epistemological model best coheres. The paper calls on the work of Joseph Henderson and his concept of the cultural unconscious, as well as exploring the contribution of Brazilian and Latin American civilization to the evolution of analytical psychology.
