The Apeiron — Anaximander’s ‘Boundless’ or ‘Infinite’ — enters the depth-psychology corpus primarily as a cosmological archetype: the undifferentiated, unlimited substrate from which all determinate existence emerges and to which it must return as expiation. Edward Edinger reads this return as a psychological paraphrase of Jung’s theology of the ego: individual existence is an injustice exacted against the primordial ground, and consciousness is literally the guilt of separation. Jean-Pierre Vernant, working from a structural-political angle, locates the Apeiron’s significance in its function as a cosmological meson — a sovereign common law holding opposites in civic equilibrium, analogous to the Greek polis rather than to monarchical rule. Richard Seaford mounts the most sustained reinterpretation, arguing that Anaximander’s Apeiron — impersonal, all-containing, unifying opposites through absorption — finds its structural homologue in monetized exchange: both money and the Apeiron are abstract, imperceptible, and exercise unifying control over a concrete multiplicity. Shirley Darcus Sullivan stresses the Apeiron’s divine, guiding character as the cosmological source of justice. Together, these readings reveal a term whose psychological, political, and economic valences remain contested — a figure for what transcends all limits precisely because it imposes limits on everything else.
like the mind, the apeiron is an abstract imperceptible entity exercising unifying control over the concrete multiplicity of which it in a sense consists.
Seaford argues that the Apeiron functions structurally like both mind and money — an abstract, imperceptible principle that unifies and governs the concrete many, providing the key analogy for his monetization thesis.

In monetised exchange, as in the cosmology of Anaximander, opposites originate in, and embody, a single substance into which they are reabsorbed.
Seaford draws an explicit structural analogy between monetary exchange and the Apeiron’s cosmological role, arguing both are systems in which opposites emerge from and return to a single undifferentiated substrate.

the rule of the apeiron is not comparable with a monarchia like that exerted by Zeus according to Hesiod… The apeiron is sovereign in the manner of a common law that imposes the same dike on each individual.
Vernant distinguishes the Apeiron’s sovereignty from monarchical divine rule, identifying it instead as a depersonalized common law — a cosmological expression of the political principle of isonomia.

the source of the universe was a divine principle which he called the Apeiron, the ‘Infinite’ or the ‘Boundless’… unlimited in time and space; it was unlimited in quality in that it displayed no qualities.
Sullivan provides the foundational exposition of the Apeiron as Anaximander’s divine, qualityless, unlimited cosmological principle that both surrounds and steers all things.

a primitive stuff must be, so to speak, a neutral in these hostilities, and must therefore have no definite characteristics of its own… the chief reason why he called his archê simply ‘the apeiron’. There were no perata in it between the hot, the cold, the wet and the dry.
Seaford, citing Guthrie, establishes why the Apeiron must be undifferentiated: as the source of all opposing qualities, it can privilege none of them and so must be without internal limits.

tau de apeirou auk estin arche: eie gar an autou peras, there is no arche to the apeiron, for that would be its limit… it envelops and governs everything.
Vernant quotes Aristotle to establish the self-grounding logical structure of the Apeiron: having no origin of its own, it is the origin of all things and the enveloping governor of the cosmos.

This Apeiron, as we noted, ‘surrounds’ and ‘guides all things’ (A 15); it is divine in nature. We may perhaps assume that what the Apeiron guides is the very way that opposites are forced to relate under time. It thus probably acts as the source of justice within the universe.
Sullivan interprets the Apeiron’s governing function as cosmological justice, linking its divine guidance of opposites to the Presocratic microcosm/macrocosm framework.

the transcendent power of money to make things as homogeneous as itself is expressed as the power to unite opposites… Was money a factor in its genesis?
Seaford presses his analogy into a genetic hypothesis: the concept of the Apeiron may have emerged not from pure observation but from the social experience of money as a transcendent unifier of opposites.

One can read Jung’s passage as a psychological paraphrase of Anaximander’s text which says that things that pass away return to that infinite stuff out of which they came and pay reparation for their injustice.
Edinger connects Anaximander’s Apeiron directly to Jungian psychology, reading the return to the boundless as a depth-psychological figure for the ego’s guilty separation from the unconscious ground.

For both Anaximander and Xenophanes there is a single divine thing that is impersonal and yet omnipotent, eternal, and in some sense the equivalent of all things. So too money is impersonal and yet omnipotent.
Seaford extends his analogy to contrast Anaximander’s relational Apeiron with Xenophanes’ more unitary deity, identifying money as the structural constant underlying both conceptual formations.

The apeiron envelops the cosmos as a whole, as a totality composed of all the various elements… It is outside our cosmos, and does not persist as an entity within it.
Vernant, citing Stokes, clarifies that the Apeiron envelops not the earth directly but the cosmos in its entirety, remaining an external, transcendent condition rather than an immanent element.

their simultaneous absorption into each other is also reabsorption into the apeiron… the opposites perish into each other.
Seaford examines the interpretive controversy over whether the mutual perishing of opposites in Anaximander’s fragment entails reabsorption into the Apeiron, defending an affirmative reading against Kahn’s objections.

ten de gen apeiron einai kai metehup’ aeros mete hupo tou ouranou periechesthai, the earth is not limited and is not enveloped, neither by the air nor by the sky.
Vernant presents Xenophanes’ contrasting cosmological use of ‘apeiron’ to describe the earth’s downward infinity, illustrating how the term circulates with variable application across early Greek thought.

The other fundamental concept of the Milesians is the term arche. It means beginning; principle; original substance; in German, urstoff, ruling element. In alchemy the term arche was translated as prima materia or first matter.
Edinger situates the Apeiron within the broader Milesian concept of arche, noting its alchemical translation as prima materia and establishing its relevance to depth-psychological archetypes of originary substance.

Being thus limited by something other than itself that both supports and envelops it (in space and in time), the earth cannot be said to be autokrates like the nous of Anaxagoras.
Vernant contrasts the limited earth with the Apeiron’s boundlessness, using the Anaximenean cosmology to show that limitation by an enveloping principle is the structural inverse of the Apeiron’s self-grounding sovereignty.

Although Anaximander is largely inaccessible behind later interpretation, this will not seriously impede us, for our focus is on almost the only text.
Seaford acknowledges the hermeneutic difficulty of accessing Anaximander’s original thought while justifying his methodological focus on the surviving fragment as the basis for his analysis of the Apeiron.

That which dominates everything cannot be limited by anything but must, on the contrary, envelop all the rest.
In discussing the cosmological organization of Hesiodic powers, Vernant articulates the structural logic — enveloping entails dominating — that underpins Anaximander’s conception of the Apeiron as supreme archê.
