The term 'synchronistic' functions in the depth-psychology corpus as both an adjective modifying specific classes of event and as a theoretical marker distinguishing Jung's acausal principle from ordinary temporal coincidence. Jung himself introduced the adjectival form to discriminate 'synchronistic' (pertaining to the meaningful coincidence of inner and outer events across time) from 'synchronous' (mere clock-time simultaneity), thereby insisting on the primacy of meaning over mere temporal contiguity. Von Franz, the most systematic elaborator of the concept, deploys 'synchronistic' across a wide range: individual clinical events, the Chinese thought-world of the Tao, divination systems, and even what she calls 'synchronistic thinking' among archaic peoples. A central tension in the corpus concerns scope — whether 'synchronistic' properly names only those unrepeatable, meaning-laden coincidences observable in individual lives, or whether it extends to cover all instances of 'acausal orderedness,' including constants of physics and the properties of natural numbers. A second tension concerns method: Jung himself acknowledged that statistical procedure stands in a relationship of complementarity to synchronistic phenomena, such that statistical observation tends to dissolve the very phenomenon it seeks to measure. Stein, Hall, and Hoeller each attend to the clinical and epistemological implications of the term within analytic practice, while Ponte and Romanyshyn situate it at the interface with quantum physics. The term's ongoing productive instability — straddling science, metaphysics, and clinical observation — explains its continued centrality in Jungian discourse.
Synchronicity designates the parallelism of time and meaning between psychic and psychophysical events, which scientific knowledge so far has been unable to reduce to a common principle.
Jung provides his canonical definition of the synchronistic as the acausal, meaning-based parallelism of psychic and physical events, distinguishing it explicitly from causal explanation.

We should rather see synchronistic phenomena in terms of the simple actuality or suchness of a contingence that cannot be reduced any further, that is, in terms of an acausal modality.
Von Franz argues that synchronistic phenomena must be understood as irreducible acausal contingencies, not causal sequences, and that ordinary language itself structurally resists this framing.
, Psyche and Matter, 2014thesis
synchronicity in the narrow sense is only a particular inst[ance]... our narrower conception of synchronicity is probably too narrow and really needs expanding.
Von Franz, following Jung, argues that individual synchronistic events are special cases of a wider principle of acausal orderedness that encompasses the discontinuities of physics and the properties of natural numbers.
, Psyche and Matter, 2014thesis
When he created the concept of synchronicity, Jung laid a foundation which might lead us to see the complementary realms of psyche and matter as one reality.
Von Franz positions the concept of synchronicity as the theoretical bridge Jung constructed toward a unified ontology of psyche and matter, grounding it in the unus mundus hypothesis.
, Psyche and Matter, 2014thesis
Jung, in his main work on synchronicity, calls synchronistic events 'acts of creation in time,' which implies nothing less than that creation is continually in progress in nature as a creatio continua.
Von Franz highlights Jung's characterization of synchronistic events as instances of ongoing creation, linking the concept to a metaphysics of continuous cosmogonic activity.
, Psyche and Matter, 2014thesis
Primitive peoples still think synchronistically today; that is, for them there is no such thing as a meaningless accident.
Von Franz grounds the synchronistic mode of perception anthropologically, arguing that archaic thinking constitutes a living precedent for Jung's acausal principle.
, Psyche and Matter, 2014thesis
Jung chose the term synchronistic rather than synchronous, and spoke of synchronicity and not synchronism.
Hoeller clarifies Jung's deliberate terminological precision: 'synchronistic' foregrounds meaning-laden coincidence across time, not mere temporal simultaneity.
, The Gnostic Jung and the Seven Sermons to the Dead, 1982thesis
synchronistic events should be taken as 'just-so' facts, as irreducible contingencies... the principle of equivalence of psychical and physical processes, which according to his experience appear in synchronistic events.
Von Franz summarizes Jung's epistemological instruction that synchronistic events are to be accepted as irreducible facts, and traces their underlying logic to the equivalence of psychic and physical processes.

the highly improbable coincidence of the inner and outer three tigers in this woman's life seems to have no common cause, and therefore it inevitably struck her as 'more than mere chance' and somehow as 'meaningful.'
Von Franz illustrates the synchronistic phenomenon through a clinical case in which an archetypal dream image and an improbable outer event coincide with no discernible causal link.
, Psyche and Matter, 2014supporting
synchronistic events form only momentary special instances in which the observer stands in a position to recognize the third, connecting element, namely the similarity of meaning in the inner and outer events.
Von Franz distinguishes synchronistic events from the broader category of acausal orderedness by identifying their defining feature as the observer's recognition of meaning-equivalence between inner and outer occurrences.

The great breakthrough, which put an end to the dualism of psyche and matter, was achieved by Jung in his work on synchronicity.
Von Franz frames Jung's work on synchronicity as a philosophical revolution overcoming the Cartesian dualism of psyche and matter.

Chinese thought altogether is to a great extent synchronistic: Every moment was for the Chinese an accidental but meaningful configuration of things and not the result of a nexus of causal chains.
Von Franz identifies Chinese cosmological thought as paradigmatically synchronistic in its orientation, providing a cultural analogue to Jung's principle.
, Psyche and Matter, 2014supporting
if synchronistic events are what they seem to be, they point to the fact of a continuous creation going all along with the stream of time.
Von Franz argues that synchronistic events, taken at face value, imply a doctrine of continuous creation in which temporal flow itself serves as the vehicle of meaning's realization.

the statistical method of science, which alone furnishes adequate proofs, stands in a relationship of complementarity to synchronicity. This means that when we observe statistically we eliminate the synchronicity phenomenon.
Jung acknowledges a methodological antinomy: statistical observation, as the gold standard of scientific proof, is structurally incompatible with the isolation of synchronistic phenomena.

when we observe statistically we eliminate the synchronicity phenomenon, and conversely, when we establish synchronicity we must abandon the statistic
Jung's letters confirm his view that synchronistic observation and statistical method are mutually exclusive epistemic stances, presenting a fundamental methodological challenge.

Jung's results at first were highly improbably 'good'... but this ultimately seems to have been just a synchronistic event in itself.
Von Franz recounts that even Jung's own statistical experiments produced a result that was itself a synchronistic event rather than stable statistical evidence for the phenomenon.

Synchronistic dreams may occur when there is a need to generate more interest in the analyst or the patient for the process of analysis.
Hall extends the synchronistic category to clinical dreamwork, arguing that synchronistic dreams serve a compensatory energic function within the analytic relationship.

The correct interpretation of a synchronistic event is essential and can only be done by a sober and disciplined mind which keeps to the necessary statements and does not run off into arbitrary assumptions.
Von Franz insists on interpretive discipline in working with synchronistic events, warning against the inflationary tendencies that the numinous quality of such occurrences tends to invite.

the archetypes are not found exclusively in the psychic sphere, but can occur just as much in circumstances that are not psychic (equivalence of an outward physical process with a psychic one).
Stein frames the synchronistic principle through Jung's concept of archetypal 'transgressivity,' which licenses the archetype's appearance in both psychic and physical registers.

the synchronicity hypothesis does not causally 'explain' psi-phenomena, but as compared with results obtained hitherto by research, it places them in a new, broader context, that is, in the realm of archetypes.
Von Franz defends the synchronicity hypothesis against reduction to parapsychological 'psi,' arguing that it recontextualizes such phenomena within archetypal psychology rather than causally explaining them.

What in nature tends to coincide in the same moment? That is also a legitimate question, the one that the Oriental peoples have asked.
Von Franz frames the synchronistic inquiry as a legitimate alternative to causal questioning, aligning it with the Oriental epistemology of the Tao.

a connection of meaning is present — a gathering of birds means mythologically that souls are coming to take someone away... in this example something of like meaning in fact takes place externally.
Von Franz illustrates the synchronistic structure through a case in which mythological meaning-resonance between inner symbol and outer event constitutes the connecting principle.

synchronicity seems more connected with time than with space. For, as Jung pointed out, 'it is not easy to understand synchronicity in time as spatial, for we cannot imagine any space in which future events are objectively present.'
Von Franz, in dialogue with Capra, argues that synchronistic phenomena are fundamentally temporal rather than spatial in their structure, complicating any simple geometric model of coincidence.

Jung observed the occurrence of synchronistic events only when an archetype was activated.
Von Franz summarizes Jung's empirical observation that the activation of an archetype is the consistent psychological precondition for the emergence of synchronistic events.

There is an obvious simultaneity between the flock of birds, in its traditional meaning, and the death of the husband.
Jung presents a clinical case — birds as death omen — to illustrate how the synchronistic link between psychic symbol and outer event is established through shared traditional meaning rather than causation.

Another physicist who particularly espoused the idea of synchronicity is J. T. Fraser... Fraser considers Jung's idea of synchronicity several times in a sympathetic fashion.
Von Franz surveys the reception of the synchronicity hypothesis among physicists and Jungian scholars, noting cross-disciplinary interest from figures such as Pauli and Fraser.

at the time of certain synchronistic incidents (see below), especially in the case of telepathy, space seems to disappear.
Von Franz notes in passing that synchronistic phenomena, particularly telepathic cases, implicate the relativization of spatial separation, linking them to Einstein-Podolsky-Rosen non-locality.

the Chinese have long tried to gather information about synchronicity by just such a 'throw of dice.'
Von Franz connects the I Ching's divinatory method to the synchronistic principle, presenting it as a practical Chinese technology for accessing acausal orderedness.
