Dr. Carl Gustav Jung, author of some of the most provocative hypotheses in modern psychology, describes what he regards as an authentic religious function in the unconscious mind.  Using a wealth of material from ancient and medieval Gnostic, alchemistic, and occultistic literature, he discusses the religious symbolism of unconscious processes and the possible continuity of religious forms that have appeared and reappeared through the centuries.    “These compact vigorous essays constitute Dr. Jung’s most sustained interpretation of the religious function in individual experience.”—Journal of Social Philosophy
