The number Four occupies a privileged and systematically elaborated position throughout the depth-psychology corpus, functioning not merely as an arithmetical quantity but as the primary archetypal symbol of wholeness, orientation, and realized totality. Jung established its centrality through multiple converging lines of evidence: the fourfold typological model of consciousness (thinking, feeling, sensation, intuition), the recurrence of quaternary structure in mandalas, alchemy, cosmology, and comparative religion, and the phenomenological observation that four appears in patients' dreams and active-imagination products precisely when integrative processes are reaching completion. Von Franz extends and systematizes this finding, distinguishing Four from Three on structural grounds: Three marks dynamic creative process, while Four denotes the establishment of visible order — the result when creative flow becomes still, measurable, and oriented. She further identifies the archetypal priority of the quaternary pattern over its Jungian psychological instantiation, insisting the four functions are derived from the archetype, not the reverse. Hamaker-Zondag adds the crucial Jungian caveat that the step from Three to Four is psychologically painful, linked to confrontation with the inferior fourth function. Edinger, Pauli, Nichols, and Bly collectively document Four's saturation across alchemical, theological, mythological, and cosmological traditions, confirming its trans-cultural status as what Jung called 'an archetypal arrangement.' The central tension in this literature is whether Four is a psychological discovery or a metaphysical given — a question the corpus deliberately leaves generative.
the number four, from our practical experience, always points to a totality and to a total conscious orientation, while the number three points to a dynamic flow of action.
Von Franz articulates the defining structural distinction between Three and Four within Jungian psychology: Four signifies completed, ordered totality rather than dynamic process.

Like the four seasons and the four quarters of heaven, the four elements are a quaternary system of orientation which always expresses a totality... The orienting system of consciousness has four aspects, which correspond to four empirical functions: thinking, feeling, sensation (sense-perception), intuition. This quaternity is an archetypal arrangement.
Jung grounds the four psychological functions in a universal archetypal quaternary structure shared by cosmological, elemental, and temporal systems of orientation.
, Alchemical Studies, 1967thesis
Jung, moreover, says that the step from three to four is painful, because in the psyche it is associated with painful insights into ourselves... the number four can, by the very fact of the confrontations, be a powerful step toward wholeness.
Hamaker-Zondag conveys Jung's insight that Four entails psychological suffering — especially through encounter with the inferior function — yet simultaneously constitutes a decisive movement toward individuation.

Jung observed in his work how tremendously significant the number four is: he discovered the four manners of psychological orientation (the four functions), while the number four in dreams, imagination, and fantasies often indicates that things are falling into place and that processes are having a good outcome.
This passage links the empirical discovery of the four functions to the broader symbolic valence of Four as a prognostic sign of psychic integration in dreamwork and imagination.

the number four symbolizes man's orientation to reality as a human being. One pictorial representation of the number four is a square, symbolic of the order superimposed by Logos.
Nichols synthesizes the encyclopedic cross-cultural catalogue of quaternary symbols into a single thesis: Four is the number of humanity's structured orientation to reality under the governance of Logos.

Like the four seasons and the four quarters of heaven, the four elements are a quaternary system of orientation which always expresses a totality... The orienting system of consciousness has four aspects, which correspond to four empirical functions.

Four is complete in that it stands for the four-gated city, the four directions, the four rivers of Paradise, the four seasons, the four letters of the Holy Name, the four horses of the sun carriage.

Jung, with his intuition, when he set forth this principle of the four functions, touched a very archetypal idea to which now an analogy from a completely different angle reappears in modern physics.
Von Franz argues, citing Pauli, that Jung's four-function model reflects a genuinely archetypal idea independently confirmed by modern physics, validating its transempirical significance.

the quaternity and the cross signify wholeness. Thus Paulinus of Nola says: Extended on the four arms of the wood of the cross, he reached out to the four quarters of the world.

The form does not come into being until the following number: four. Von Franz emphasizes that within Jungian psychology three constantly recurs as a dynamic process.
Drawing on von Franz, Hamaker-Zondag establishes Four as the number at which form becomes actualized in the concrete world, completing the sequence from unity through dynamic process.

The fourfold Mercurius is also the tree or its spiritus vegetativus... A god with four faces is mentioned as early as the Pyramid Texts of the fourth and fifth dynasties. The faces obviously refer to the four quarters of heaven — that is, the god is all-seeing.

Three of the four orienting functions are available to consciousness... His inferior function will be feeling (valuation), which remains in a retarded state and is contaminated with the unconscious.

In this symbolic image we see, first of all, an indication of the quaternary in the cross, four lines being arranged so as to meet in a common point. Joined with the number 3, which denotes the moon, the sun, and fire, this [quaternary] will produce the number 7.
