On Divination And Synchronicity by Marie-Louise von Franz

The Psychology of Meaningful Chance

This book examines traditional divinatory practices and the phenomenon of meaningful coincidences as expressions of the unconscious, arguing that divination techniques (I Ching, astrology, rune-casting, pendulums, etc.) function as symbolic mediators between inner psychic states and outer events; through case studies and theoretical discussion it presents synchronicity as an acausal connecting principle rooted in archetypal patterns of the collective unconscious, useful for revealing unconscious content and guiding psychological development while warning against mere projection and emphasizing careful, reflective interpretation.
