The One

The term ‘The One’ occupies a singular and demanding position within the depth-psychology corpus, where it arrives freighted with millennia of philosophical and theological elaboration. Its most sustained treatment appears in Gnostic sources collected by Meyer, where The One designates the supreme, self-subsistent principle of negative theology: illimitable, unnameable, and beyond the category of god itself. This apophatic register — defining The One by what it is not — finds precise parallels in John of Damascus’s orthodox apophaticism and in Plato’s Parmenides, where the dialectical status of the one generates irresolvable paradoxes concerning being, predication, and multiplicity. Seaford’s analysis of Parmenides locates the concept within early Greek monism and its encounter with logical contradiction. The Trinitarian discourse of John of Damascus refracts the term into the tension between unity of essence and plurality of persons — ‘They Two are One God’ — a formulation that resonates through Western theological anthropology. Zimmer’s Vedantic appropriation brings ‘The One’ into dialogue with Atman and the formula tat tvam asi, grounding it in Indian non-dual metaphysics. Von Franz’s alchemical and creation-myth contexts situate the problem of The One against primordial twoness, duality, and the genesis of opposites. Across these voices, The One functions less as a psychological concept than as the apophatic horizon against which all psychological differentiation and individuation unfolds.

The One is a sovereign that has nothing over it. It is God and parent, father of all, the invisible one that is over all, that is incorruptible, that is pure light at which no eye can gaze.

This passage presents the fullest positive statement of The One as the supreme Gnostic principle — invisible, self-sufficient, illimitable, and absolutely beyond all predication, constituting the foundational apophatic theology of the Sethian tradition.

The One is not corporeal and it is not incorporeal. The One is not large and it is not small. It is impossible to say, How much is it? What [kind is it]? For no one can understand it.

Meyer describes the negative theology of The One as a ‘carefully articulated’ systematic apophasis, in which even apparently contradictory predications are denied, underscoring the absolute transcendence of the Gnostic first principle.

If one is, one partakes of being, which is not the same with one; the words ‘being’ and ‘one’ have different meanings… one is never one, and in this way the one, if it is, becomes many and infinite.

Plato’s Parmenides demonstrates through dialectical analysis that the hypothesis ‘the one is’ immediately generates infinite multiplicity, exposing the paradox at the heart of any monist ontology that attempts to predicate being of The One.

The one cannot possibly partake of being? That is the inference. Then the one is not at all? Clearly not. Then the one does not exist in such way as to be one.

Pursuing the hypothesis that the one does not partake of time, Plato arrives at the radical conclusion that the pure one can neither be said to exist nor to be one, anticipating the apophatic theology of later Neoplatonism and Gnosticism.

we may not easily persuade ourselves with Zeller that by the ‘one’ he means the Idea; and that he is seeking to prove indirectly the unity of the Idea in the multiplicity of phenomena.

The introduction to the Parmenides surveys competing interpretations of ‘the one’ — sceptical, Heracleitean, and Zellerite — and in rejecting them frames the term as irreducible to any single school’s metaphysical program.

What is (Being) is one, continuous and homogeneous… Parmenides surely had this kind of cosmological view in mind, but by himself taking it to a logical extreme comes to a conclusion that is in fact opposed both to this earlier cosmology and to the views of people in general.

Seaford situates Parmenides’ monism historically, arguing that the claim ‘Being is one’ emerges from and radically subverts earlier Milesian cosmology, producing conclusions that are paradoxical precisely because they retain monism while negating ordinary experience.

They Two are One God. You cannot confuse Them together, for They Two are not One Person… In confessing the Father it confesses the Son; it believes in the Son in believing in the Father.

John of Damascus articulates the Trinitarian logic in which ‘one God’ signifies unity of essence without collapse into singularity of person, demonstrating how Nicene theology both affirms and complicates the ontological claim of The One.

They Who are one in essence are not one person, and He Who is not one person with Him Who is, is yet so free from difference from Him that They Two are One God.

This passage formulates the central Trinitarian paradox — unity of essence coexisting with irreducible plurality of persons — as the orthodox Christian answer to the metaphysical problem of The One and the many.

If thou wrongly employest the confession of one God to deny the Godhead of Christ, on the ground that where one God exists He must be regarded as solitary, and that to be One is characteristic and peculiar to Him Who is One.

Damascus polemically exposes the heretical misuse of ‘The One’ as a device to deny Christ’s divinity, arguing that exclusive oneness as solitude misreads the relational ontology inherent in the confession of one God.

This whole world has that as its soul; that is Reality; that is Ātman; that art thou, Śvetaketu… reduced the entire spectacle of nature to its single, all-pervading, most subtle, absolutely intangible, hidden essence.

Zimmer presents the Vedantic formula tat tvam asi as the Indian equivalent of The One, wherein the single all-pervading essence (Atman-Brahman) absorbs the multiplicity of phenomena into an undifferentiated ground of reality.

Our Lord prays to His Father that those who shall believe in Him may be one, and as He is in the Father and the Father in Him, so all may be one in Them.

The Johannine prayer for unity among believers is interpreted as grounding oneness not in mere agreement of wills but in participation in the ontological unity of Father and Son, extending the metaphysics of The One into ecclesiology.

The Deity alone is motionless, moving the universe by immobility… it is impossible to explain what He is in His essence, and it befits us the rather to hold discourse about His absolute separation from all things.

John of Damascus imports Aristotelian cosmology — the unmoved mover — into Christian apophatic theology, aligning the divine One with absolute separateness from all things and the impossibility of positive essential predication.

If they had no parts they would be simply one, and parts imply a whole to which they belong… For a part, if not a part of one, must be a part of all but this one.

Plato’s argument that parts presuppose wholes and wholes presuppose the one develops the relational necessity of The One as a logical condition for any plurality or partition to be intelligible.

In the passage from one to many and from many to one, the one is neither one nor many, neither separated nor aggregated.

Plato describes the transitional ‘moment’ in which the one passes between states — one and many, like and unlike — as a condition outside time and predication, suggesting that The One as pure principle lies beyond all dialectical determination.

One, then, alone is one, and two do not exist? Clearly not. And if there are not two, there is no contact? There is not.

The argument demonstrates that if The One is truly singular, relationality — contact with itself or others — becomes impossible, pressing toward the Neoplatonic insight that The One exceeds relational being entirely.

these three are One, [which the Philosopher would have to be] body, spirit, and soul, for all perfection consisteth in the number three.

Von Franz’s alchemical commentary draws the Trinitarian formula ‘three are One’ into correspondence with the triad of body, spirit, and soul, locating the theme of The One within the quaternary and ternary symbolism of alchemical perfection.

God then is infinite and incomprehensible and all that is comprehensible about Him is His infinity and incomprehensibility.

In establishing that God transcends essence and knowledge alike, John of Damascus articulates the apophatic logic that governs the concept of The One — that its only positive content is the negation of all delimiting predication.

We may not sever Him from Thee, or make Him one of a plurality of Gods, on any plea of difference of nature.

Damascus’s theological method insists that christological discourse must preserve the indivisibility of the divine One even while confessing eternal generation, establishing the boundary condition for any theological pluralism.
