synchronicity

Synchronicity () is a concept introduced by Carl Jung, founder of analytical psychology, to describe events that coincide in time and appear meaningfully related, yet lack a discoverable causal connection. Jung held that this was a healthy function of the mind, although it can become harmful within psychosis.

Jung developed the theory as a hypothetical noncausal principle serving as the intersubjective or philosophically objective connection between these seemingly meaningful coincidences. After coining the term in the late 1920s Jung developed the concept with physicist Wolfgang Pauli through correspondence and in their 1952 work The Interpretation of Nature and the Psyche. This culminated in the Pauli–Jung conjecture. Jung and Pauli's view was that, just as causal connections can provide a meaningful understanding of the psyche and the world, so too may acausal connections.
