The
concept of synchronicity was first described in this terminology by Carl Gustav
Jung in the 1920s. The concept does not question, or compete with, the notion
of causality. Instead, it maintains that just as events may be grouped by
causes, they may also be grouped by finalities, a meaningful principle. Jung
coined the word synchronicities to describe what he called “temporally
coincident occurrences of acausal events.” He variously described synchronicities
as an “acausal connecting principle,” “meaningful coincidences” and “acausal
parallelisms.”
