Synchronicity and the i ching

The I Ching and synchronicity are not merely related — the oracle is, for Jung, the paradigm case of the synchronistic principle in action, the instrument through which he first articulated what he would eventually name. Writing to Pascual Jordan in 1934, Jung noted plainly that "Chinese science is based on the principle of synchronicity, or parallelism in time" and that "the standard work on this subject is the I Ching" (Letters, 1973). The oracle did not illustrate a theory Jung had already formed; it helped generate the theory itself.

The philosophical premise is a radical alternative to causal thinking. Western science asks how D arose from C, which arose from B — a sequential story of efficient causes. The I Ching asks a different question entirely: what is the quality of this moment, and what does the simultaneous configuration of events — inner and outer, psychic and physical — disclose about it? As Jung formulates it in his foreword to the Wilhelm/Baynes translation:

Whoever invented the I Ching was convinced that the hexagram worked out in a certain moment coincided with the latter in quality no less than in time. To him the hexagram was the exponent of the moment in which it was cast — even more so than the hours of the clock or the divisions of the calendar could be — inasmuch as the hexagram was understood to be an indicator of the essential situation prevailing at the moment of its origin.

This is the core claim: the fall of the coins or the division of the yarrow stalks does not cause the hexagram to correspond to the questioner's situation. Nor does the situation cause the coins to fall as they do. Both are exponents of the same moment — expressions of a single qualitative instant whose meaning is legible precisely because inner and outer share a common temporal fabric. Jung named this "synchronicity," a concept, as he put it in Psychology and Religion, that "formulates a point of view diametrically opposed to that of causality" (CW 11, §972).

The technique enforces this logic structurally. King Wen and the Duke of Chou, Jung argues in The Structure and Dynamics of the Psyche, devised a method that "forced nature to answer in even and odd numbers" — Yin and Yang — which "are found both in the unconscious and in nature in the characteristic form of opposites" and therefore "form the tertium comparationis between the psychic inner world and the physical outer world" (CW 8, §865). The binary structure of the hexagram is not arbitrary; it is the formal element that makes the psychophysical coincidence legible. Von Franz extends this point in Psyche and Matter (2014): the natural numbers are archetypes of order, and the I Ching's numerical structure is precisely the site where acausal meaning and physical event coincide — number as the bridge between the two poles of experience.

What distinguishes Jung's account from earlier Western analogues — Leibniz's harmonia praestabilita, the Stoic doctrine of cosmic sympathy — is the insistence on inconstancy. Leibniz postulated a constant non-causal connection between all things. Jung holds that synchronistic events arise "only inconstantly, sporadically, and arbitrarily, since ultimately they are dependent upon an excited archetypal situation in the observer" (von Franz, Psyche and Matter, 2014). The I Ching does not tap a continuous cosmic current; it catches the qualitative character of a specific, unrepeatable moment. This is why the experiment cannot be repeated: the original situation cannot be reconstructed, and any second consultation would occur within a new context already shaped by the first.

Clarke's study of Jung and Eastern thought captures the epistemological stakes clearly: what intrigued Jung about the oracle was not merely its utility as a self-knowledge tool, but the fact that it "pointed to a way of conceptualising reality in a wholly different way from that which had been established in the West from the time of the Scientific Revolution" (Clarke, 1994). The Chinese mind, as Jung observed in his Tavistock Lectures, asks of any configuration of events — an old hat, a dead fish, a shoe washed up together on the shore — not "what caused this?" but "what does it mean that these things are together?" The I Ching is the systematic, millennia-refined instrument for answering that second question.

The sole criterion of validity, Jung acknowledges, is the observer's judgment that the hexagram text amounts to a true rendering of the psychic condition. This is not a weakness of the method but its nature: synchronistic events are not statistically testable in the ordinary sense, because situations are unique and cannot be repeated under controlled conditions. The I Ching is an empirical instrument in a different register — one that takes the qualitative structure of the unrepeatable moment as its object.
