The term 'Jordan' enters the depth-psychology corpus along two distinct but occasionally convergent axes. The first is mythological and symbolic: in Jungian exegesis, the River Jordan functions as a threshold image—a site of purification, initiation, and ontological transformation. Von Franz's commentary on the Aurora Consurgens reads Naaman's sevenfold washing in the Jordan as an alchemical prefiguration of baptism, linking the river's waters to the sevenfold planetary symbolism and the doctrine of the Holy Spirit's gifts. Jung's Aion extends this further, treating the 'upwards-flowing Jordan' as a Gnostic cosmogonic symbol equated with the hermaphroditic Logos, the horn of the moon, and the ascending libido that begets gods. The second axis is biographical and scientific: Pascual Jordan, the German quantum physicist, figures in Jung's letters as an interlocutor on the border territory between modern physics and psychic phenomena. Jung corresponds with Pascual Jordan about clairvoyance, synchronicity, and the convergence of quantum theory with depth psychology—a dialogue mediated also through Pauli. In Psychological Types, a third 'Jordan'—the British psychologist Furneaux Jordan—serves as a primary source for Jung's typology of the introverted and extraverted characters. These three registers—mythic river, quantum physicist, and typological predecessor—give the term an unexpectedly rich and polysemous presence in the corpus.
Zeesar is named the 'upwards-flowing Jordan.' The Jordan was caused by Jesus to flow upstream; it is the rising flood and this, as already mentioned, is the begetter of gods.
Jung identifies the upwards-flowing Jordan as a Gnostic cosmogonic symbol equivalent to the hermaphroditic Logos, the quaternio, and the celestial horn of the moon, making the river an image of ascending, generative psychic energy.

And to Naaman was it said: Go and wash seven times in the Jordan and thou shalt be clean. For there is one baptism for the remission of sins.
Von Franz reads Naaman's sevenfold immersion in the Jordan as an alchemical-baptismal symbol integrating planetary numerology, purification from original sin, and the doctrine of the Holy Spirit.

Jordan treats clairvoyance in space. He postulates an infinite number of time dimensions roughly corresponding to Jordan's 'intermediate stages.'
Jung's correspondence reveals Pascual Jordan as a key scientific interlocutor on parapsychology and synchronicity, whose quantum-physical treatment of clairvoyance Jung compares to Dunne's multi-dimensional theory of time.

It is my belief, therefore, that Jordan's intermediate group can be resolved into the sensation and intuitive types.
Jung argues that Furneaux Jordan's typological 'intermediate group' dissolves into his own sensation and intuitive types, demonstrating how Jordan's empirical observations prefigure but require revision by analytical psychology.

The characterization of types in terms of affectivity seems to me the really important aspect of Jordan's work.
Jung credits Furneaux Jordan's affective typology as a genuine anticipation of the introvert-extravert distinction, while noting its conflation of the active type with the less impassioned as a methodological error.

the reflective, contemplative nature of the introvert is compensated by a condition in which instinct and sensation are unconscious and archaic.
In the context of evaluating Jordan's typology, Jung explicates how the introvert's rise above archaic impulse to abstraction is the compensatory dynamic underlying Furneaux Jordan's 'more impassioned' character.

Wigner and Jordan proved that also in this case operators can be defined which are functions of the ordinary space-time coordinates.
Pauli cites the Wigner-Jordan formalism in quantum mechanics as the technical foundation for the exclusion principle, contextualizing Pascual Jordan's scientific standing within the physics-psyche dialogue.

the baptism of John was proclaimed with a view to... the divine Christ-nature descended on the man Jesus at his baptism.
Edinger's discussion of Gnostic baptismal symbolism provides the broader ritual-initiatory context within which the Jordan river's significance as threshold and transformative site can be understood.
