The term ‘interior’ functions across the depth-psychology corpus as a charged locus where the question of psychic reality is most sharply contested. Its range of significations spans the neurobiological, the phenomenological, the architectural-symbolic, and the strictly logical. Damasio anchors the interior in the homeostatic viscera — the ‘old interior world’ of chemical and electrochemical signaling from which feelings, and ultimately consciousness, are fashioned. Neumann historicizes this dimension, arguing that the dawn-period human inhabits an interior world ‘without being aware that so,’ experienced as outer reality. Giegerich radicalizes the concept philosophically: interiority is not located in any individual psyche but constitutes the very Notion of psychology itself — ‘the discipline of interiority.’ Hillman dramatizes the dialectic between containing the soul inside (as psychological factor) and the soul’s demand to move beyond that containment. Tarnas traces a civilizational arc in which disenchanted cosmologies force the ‘cultural psyche to the interior.’ Campbell and Spengler, via architecture, identify interior space as a symbol of spiritual inwardness absent from Classical culture. Sardello warns that matter conceived as pure energy acquires no interior and thus no soul. Together these voices make ‘interior’ one of the most theoretically generative and contested terms in depth psychology: the site where biology, cosmology, clinical practice, and philosophical logic converge on the question of what it means to have an inside at all.
Psychology is the discipline of interiority. But this interiority is not in me, not in you, not in anybody, also not in the depth of any thing out there. It is in its (psychology’s) own Notion itself.
Giegerich argues that psychological interiority is not a property of persons or objects but is constitutive of psychology’s own self-reflexive Notion, relocating ‘interior’ from empirical subjectivity to logical structure.

the impenetrable boundaries of the disenchanted cosmic vision began again to force the cultural psyche to the interior. Pascal was among the first to confront the dark entailments of the new cosmic reality.
Tarnas locates a civilizational pattern in which the closure of the outer cosmos repeatedly drives the collective psyche inward, making ‘interior’ the refuge and generative space of new spiritual and psychological forms.

In our dreams we inhabit an interior world without being aware that we do so, for all the figures in the dream are the images, symbols, and projections of interior processes.
Neumann identifies the interior world as the primordial matrix of symbolic experience, shared by dreams and the dawn-period of humanity, where inside and outside remain undifferentiated.

Just wanting to keep you inside and psychological makes you a prisoner? Soul-Voice. A prisoner in your psychology. You have imprisoned me in your psychological system, preventing me from appearing wherever I please.
Hillman dramatizes the tension between the therapeutic imperative to internalize the soul as a psychological factor and the soul’s own demand to exceed that containment, treating ‘interior’ as both sanctuary and cage.

for Classical man ‘the Temple of the Body, too, had no interior.’ The mosque, in contrast, was all interior: an architectural likeness of the world-cavern, which appears to the Levantine mind to be the proper symbol of the spiritual form of the universe.
Campbell, drawing on Spengler, uses architectural contrast between Greek temple and mosque to argue that the very capacity for interiority marks a historical shift in spiritual self-understanding.

using images made from the oldest components of the organism’s interior — the processes of metabolic chemistry largely carried out in viscera and in the blood circulation — nature gradually fashioned feelings.
Damasio grounds the psychological interior in evolutionary biology, arguing that feelings emerge from images of the organism’s visceral interior, establishing a continuum from homeostasis to consciousness.

the ‘interior’ and the nervous system form an interactive complex; the ‘exterior’ and the nervous system do not.
Damasio distinguishes the interior as uniquely co-constitutive with the nervous system, making interiority a functional rather than merely spatial concept in the biology of mind.

the esophagus is an excellent image of one of the soul’s chief functions: to transfer material of the outside world into the interior. But in this dream it is made of an unnatural substance that stands for the superficiality of our age, plastic.
Moore reads a dream image as a diagnosis of modernity’s failure to achieve genuine interiority, figuring soul-work as the deepening conduit between outer experience and inner nourishment.

matter which has no interior — results in matter that has no radiation at all; the balance between exterior and interior becomes disturbed, divided into an absolute polarity.
Sardello argues that the modern imagination of matter as pure energy destroys the interior dimension of things, with pathological consequences for soul and body alike.

the borderline cases between inert matter and the living being are precisely cases of processes that unfold according to the dimensions of exteriority and interiority.
Simondon situates interior/exterior as the ontological threshold between inert matter and living individuation, making the development of genuine interiority coextensive with the emergence of life.

information is both interior and exterior; it expresses the limits of a subset; it is the mediation between the set and each subset.
Simondon recasts interiority as a relational, informational concept — neither purely contained nor purely exposed — that mediates between individual subsystems and the larger set to which they belong.

There are two kinds of worlds inside our organisms. Let us call them the old interior world and the not so old. The old internal world is concerned with basic homeostasis.
Damasio introduces a stratified model of organic interiority, distinguishing an ancient visceral interior from a more recent somatic one, both contributing to the construction of mental life.

The interior maintains its internal equilibrium based on the information received through the boundary which opposes entropy.
Mizen, drawing on Friston’s Markov Blanket model, frames the interior as an information-bounded system maintaining homeostatic equilibrium against environmental entropy, linking biological and psychological selfhood.

Greek notions of femaleness interact with the basic Greek principle that the outer world, the kosmos, is made of the same fabric and structure as the inner.
Padel traces how Greek culture mapped the human interior — paradigmatically the female body — onto cosmic and chthonic structures, showing that interiority was always already gendered and cosmological.

he had begun to let the group into his less-than-perfect ‘interior’ world. Perhaps, he said, the dream reflected his fear that the new members coming the next week would not take proper care of his interior.
Yalom illustrates clinically how the ‘interior world’ functions as a protected intimate space whose exposure to new relational figures activates vulnerability and defensive anxiety.

Evolution has developed telesenses with which external objects connect to us neurally and mentally first and only reach our physiological interior via the intermediate agency of the affective filter.
Damasio argues that the affective filter is the gateway through which external perception reaches the physiological interior, positioning affect as the mediating threshold between world and inner life.
