The Logos Principle occupies a pivotal and contested position across the depth-psychology corpus, functioning simultaneously as a cosmological category, a psychological typology, and an archetypal polarity. Jung appropriated the term from its ancient Heraclitean and Stoic registers—where Logos designated the universal ordering principle immanent in all things—and redeployed it as the masculine psychological principle set in dialectical opposition to Eros. In Jungian usage, Logos denotes rationality, discrimination, and intellective achievement, and is associated with the masculine component of the psyche in both men and women; the tension between Logos and Eros organizes Jung's understanding of psychological wholeness, anima, animus, and gender. Andrew Samuels is careful to note that these are symbolic rather than anatomical categories, though the gendered nomenclature remains theoretically fraught. Beyond Jung, the corpus traces the term's lineage through Heraclitus—for whom Logos was the 'common' principle structuring cosmic opposites—through Stoic pneumatology (logos spermatikos), through Plotinus's Reason-Principle, and into Gnostic and Christian theology. Hillman complicates the standard opposition by locating a logos function within Eros itself. McGilchrist draws an illuminating parallel with the Chinese concept of lǐ. The central tension running through the corpus is whether Logos is irreducibly rational and masculine or whether it names something anterior to that binary—a principle of ordered form that encompasses and generates differentiation itself.
The old man represents a spiritual principle that could be designated as Logos, and the maiden represents an unspiritual principle of feeling that could be called Eros.
Jung's Red Book offers his most direct phenomenological definition of the Logos Principle as a spiritual, ordering, and prophetic faculty of the psyche, structurally opposed to Eros and figured by the archetype of the Wise Old Man.

The masculine principle he terms Logos ('the word', hence rationality, logic, intellect, achievement), and the feminine principle Eros... 'it is the function of Eros to unite what Logos has sundered'.
Samuels summarizes and critically frames Jung's Logos/Eros polarity, clarifying that these are archetypal psychological principles independent of anatomical sex, though clouded by gendered terminology.

Animus in a man is not a person, it is his conscious principle, and then I call it Logos.
Jung equates the conscious masculine principle with Logos and distinguishes it from the animus as a personal complex, anchoring the term in his typology of conscious psychological functioning.

According to the Stoics the basic principle of the universe was the logos. It was commonly spoken of as the logos spermatikos, usually translated as 'seminal reason.' This refers to the divine word that is cast like a seed into matter.
Edinger traces the Stoic cosmological substrate of the Logos Principle, presenting logos spermatikos as the divine formative reason immanent in matter, a key historical source for depth-psychological appropriations of the term.

This Reason-Principle, then—let us dare the definition in the hope of conveying the truth—this Logos is not the Intellectual Principle unmingled, not the Absolute Divine Intellect; nor does it descend from the pure Soul alone; it is a dependent of that Soul.
Plotinus distinguishes his Logos (Reason-Principle) from pure Intellect, positioning it as a mediating principle dependent on Soul—a nuance that informs later depth-psychological distinctions between intellect and the ordering principle.

He postulates that a divine principle exists that carries out on a cosmic level a similar activity. The divinity, by thinking and 'speaking' things, forms them.
Sullivan clarifies Heraclitus's Logos as a cosmic principle of articulate formation shared between divine activity and human speech, providing the pre-Socratic foundation for all subsequent Logos doctrines in the corpus.

Heraclitus thinks that in logos, its form and function, the nature of the divine can be grasped. This logos is not speech alone, but speech that reflects thinking (phronesis).
Sullivan establishes that Heraclitus's Logos is a universal cognitive-divine principle irreducible to mere speech, encompassing thinking, cosmological order, and communal intelligibility.

Logos appears within eros itself as the inhibiting daimon with which one can speak, which acts as spiritus rector, and which has an upward, pneumatic tendency.
Hillman destabilizes the neat Logos/Eros binary by arguing that Logos functions as an immanent daemon within Eros itself, complicating any simple identification of Logos with masculine rationality.

The universe itself is a language, logos, a divine expression varied and unified in nature.
Sullivan articulates Heraclitus's identification of the universe with Logos as a semiotic and psychic principle, connecting the cosmic ordering function to the fiery, capacious psyche.

The Logos is here clearly in the Greek sense the principle of order, but at the same time a divine entity and as such substantially involved in what he affects.
Jonas situates the Gnostic Logos as simultaneously cosmic ordering principle and divine presence substantially entangled with matter, a formulation that bridges Stoic and Christian-Gnostic appropriations.

It is perhaps more like what Heraclitus called the logos. At that stage logos had not yet come to mean 'reason' in the rather limited modern sense, instead meaning the common principle that makes complexity, beauty and meaningful order arise.
McGilchrist recovers the pre-rationalist breadth of Heraclitean Logos, aligning it with the Chinese concept of lǐ as dynamic ordered pattern, and resisting its reduction to mere discursive reason.

A verbal logos in which this aspect is especially important is the sacred (hieros) logos spoken in mystic ritual for the instruction of the initiands.
Seaford traces the ritual and monetary dimensions of Logos in Heraclitus, showing how the term carried the connotation of a complete, disclosing account with initiatory and sacred functions.

He terms this divinity logos. The exact nature of this logos is difficult to discern... It seems that he uses the term to indicate a thought-process having a structured form.
Sullivan acknowledges the deliberate opacity of Heraclitus's Logos while affirming its designation as a structured divine thought-process operative at cosmic and human scales.
