The term 'limit case' appears in the depth-psychology corpus not as a clinical diagnostic category but as a philosophical and ontological operator — a device by which thinkers establish the primacy or priority of one phenomenon over another by demonstrating that the supposedly fundamental term is actually a degenerate instance of what it was believed to explain. Its most systematic deployment appears in McGilchrist's The Matter With Things, where the maneuver is performed repeatedly and deliberately: randomness is revealed as the limit case of order, simplicity as the limit case of complexity, inanimacy as the limit case of animacy, and the actual as the limit case of the potential. In each inversion, what modernity took to be the baseline or ground is reconstituted as a special, attenuated, or impoverished instance of a richer prior reality. This constitutes a profound challenge to reductionist ontologies. The philosophical precedent for such inversions runs through Simondon's account of the individual as a 'limited being' defined by dynamic polarization rather than substance, through Derrida's interrogation of limit itself as structurally oblique, and through the Presocratic tension between peras (limit) and apeiron (the unlimited) traced by Seaford. Across these registers, the limit case functions simultaneously as a logical tool, an ontological claim, and a heuristic for exposing the hidden assumptions of dominant world-pictures.

randomness merely the limit case of order, which is the universal norm… inanimacy is better regarded as the limit case of animacy… The actual is the limit case o[f the potential]
McGilchrist performs a systematic ontological inversion, arguing that what modernity treats as fundamental — randomness, simplicity, inanimacy, actuality — are each impoverished or degenerate limit cases of richer prior realities.

randomness merely the limit case of order, which is the universal norm… inanimacy is better regarded as the limit case of animacy… The actual is the limit case o[f the potential]
Parallel to the above, this edition of the passage establishes the limit case as the central structural device of McGilchrist's ontological revisionism.

relation is observable as an active limit, and its type of reality is that of a limit… a limited being is a polarizing being that possesses an indefinite dynamism of growth with respect to an amorphous milieu
Simondon reframes the individual as constitutively defined by an active, relational limit rather than by substance, positioning limit as the ontological condition of dynamic individuation rather than a mere boundary.

the point both connects and limits the length — it is the beginning of one and the end of another… if you consider the one point as two, an arrest or pause is necessary, if the same point is to be both beginning and end
Derrida, via Aristotle and Bergson, shows that the 'now' cannot function as a simple limit point without generating paradox, destabilizing any account of limit as a clean boundary between states.

the issue would be less to displace a given determined limit than to work toward the concept of limit and the limit of the concept… if the limit in general… is structurally oblique
Derrida argues that limit itself cannot be straightforwardly determined, that the concept of limit is always already oblique, making any limit case philosophically unstable.

currency (nomisma) is 'a limiting factor (peras)' of exchange… In acquiring a monetary price [the vase is] delimited from that unlimited continuum
Seaford traces the Presocratic philosophical tension between peras and apeiron to the social experience of money, in which a commodity acquires a determinate limit within an otherwise unlimited continuum of value.

'holds the limits of all things' seems to connect mind with cosmos, implying a cosmic role for the mind as agent of the limitation… antithetical also to the new unlimit of money
Seaford shows how Presocratic thought projects mental limitation onto the cosmos, positioning mind as the agent that imposes limit on the unlimited — a cosmological analogon to the limit case structure.

the making of money is, as Solon and Aristotle pointed out, unlimited… Money may seem unlimited internally (as homogeneous), and ex[ternally]
Seaford contrasts the limit-imposing function of culture and ritual with money's structural unlimitedness, illuminating how the limit/unlimited polarity organizes early Greek cosmological and social thought.

This power is called Limit (horos): by him she was stopped, consolidated, brought back to herself, and convinced that the Father [is incomprehensible]
In Gnostic cosmology, Limit (horos) functions as a salvific power that arrests the Sophia's dissolution into the abyss, making limit an ontologically necessary constraint that preserves individual being.

These spatial boundaries mark out the limits within which each type of power is contained… That which dominates everything cannot be limited by anything but must… envelop all the rest
Vernant shows how archaic Greek thought conceives divine power through the logic of limit and envelopment: what is unlimited dominates by containing all limits, a structure analogous to the limit case's ontological hierarchy.

a corpuscle which cannot be characterized by a rigorously fixed mass… cannot even receive an upper limit for a possible increase of mass
Simondon uses the relativistic electron to illustrate how modern physics dissolves fixed limits on fundamental quantities, undermining atomist substantialism and opening toward a physics of relation.

the notion of justice… is a notion of the equitable distribution of finite and limited resources. Both the meaningfulness of these values and their value or goodness seem to depend upon… our human context of limitation
Nussbaum argues that ethical values such as justice derive their meaning from a human condition of finitude and limited resources, suggesting that limitation is constitutive of rather than merely restrictive of moral life.
