Was C.G. Jung a Mystic?

C.G. Jung, the father of analytical psychology, explored the realms of thought and intuition. He devoted many years to an in-depth study of alchemy and closely observed the range of the occult; he was interested in anthropology and in nuclear physics. He liked to consider himself a scientist. But was Jung a "mystic"? Aniela Jaffé, his editor, collaborator and confidante, addressed this question and others in her last book of essays.
