The term 'Other' occupies a contested and multivalent position across the depth-psychological corpus. At its most philosophically foundational, the Other appears in Platonic dialectic—particularly in the Sophist and Parmenides—as an ontological category: not-being is not the opposite of being but simply 'the other,' a principle that runs through all things and conditions every act of differentiation. This Platonic inheritance reverberates through later phenomenological and psychological thought. In Ricoeur's engagement with Lévinas, the Other becomes an ethical absolute, an exteriority that summons the self from outside and institutes responsibility in an irreducibly asymmetric relation. Byung-Chul Han's social critique identifies the pathological consequences of the Other's disappearance: the late-modern achievement-subject, freed from the 'commanding Other,' collapses into narcissistic self-relation and psychic disturbance. Gallagher's embodied phenomenology locates the Other at the very origin of self-awareness, arguing that the newborn's perception of the other's movement is coupled intermodally with proprioceptive self-experience. Yalom addresses the Other through the lens of existential isolation and the transformation of love from passive reception to active giving. Across these registers—ontological, ethical, social, embodied—the corpus treats the Other not as a peripheral concept but as the constitutive term against which selfhood, being, and relatedness are measured.
Since the initiative belongs wholly to the Other, it is in the accusative—a mode well named—that the I is met by the injunction and made capable of answering
Ricoeur, reading Lévinas, argues that the Other commands with absolute asymmetry, addressing the self in the accusative and constituting ethical subjectivity through an irreducible exteriority.

not-being is the principle of the other which runs through all things, being not excepted. And 'being' is one thing, and 'not-being' includes and is all other things. And not-being is not the opposite of being, but only the other.
The Sophist establishes 'the Other' as a universal ontological principle—the form of difference that permeates all things—distinguishing it carefully from simple negation or opposition.

Freedom from the Other switches into narcissistic self-relation, which occasions many of the psychic disturbances afflicting today's achievement-subject. The absence of relation to the Other causes a crisis of gratification.
Han argues that the modern subject's emancipation from the 'commanding Other' does not produce freedom but rather narcissistic closure and a resulting psychic crisis.

There exists in the newborn infant a natural intermodal coupling between self and other, one that does not involve a confused experience.
Gallagher's embodied phenomenology demonstrates that the self-other distinction is neurologically grounded from birth in intermodal coupling, making the Other constitutive of somatic self-awareness from the very beginning.

the link to the other person is immediate; experientially, and not just objectively, we are born into a world of others.
Gallagher argues that the relation to the Other is phenomenologically primary, not inferred—we are experientially born into a world of others rather than constructing it from analogy.

What is the meaning of these two words, 'same' and 'other'? Are they two new kinds other than the three, and yet always of necessity intermingling with them?
The Sophist's dialogue interrogates whether Sameness and Otherness constitute irreducible ontological categories distinct from being, motion, and rest, establishing the Other as a fifth fundamental form.

If other than itself it would be other than one, and would not be one... Then not by virtue of being one will it be other.
Parmenides' dialectic explores the paradox that the One cannot be other than itself or other than the Other by virtue of its own nature, probing the logical limits of identity and difference.
, Parmenides, -370supporting
the terms 'other' and 'different' are synonymous... Other means other than other, and different, different from the different.
Parmenides clarifies that otherness is a relational and irreducibly differential category, requiring a term from which difference is measured—a move that anticipates later phenomenological accounts of alterity.

as the individual overcomes egocentricity, the needs of the other become as important as his or her own; and gradually the individual transforms the concept of love from 'being loved' into 'loving.'
Yalom, drawing on Fromm, traces the developmental arc by which the Other ceases to be merely instrumental to self-gratification and becomes the locus of mature, active love.

one's sense of self can be expanded to include, or feel a sense of unity with, other people and one's environment.
Yaden's self-transcendence research operationalizes self/other overlap as a measurable construct, linking degrees of boundary dissolution with the Other to prosocial behavior and intimacy.

the only way to relate on the level of the inferior function is by what Jung calls bush politeness.
Von Franz illustrates through a clinical anecdote that authentic encounter with the Other at the level of psychological vulnerability demands ritual deference rather than direct confrontation.

Through the kolossos, the dead man returns to the light of day and manifests his presence in the sight of the living. It is a peculiar and ambiguous presence that is also the sign of an absence.
Vernant's analysis of the kolossos figure shows how ancient Greeks materialized the radical alterity of the dead—the Other as one who is irreversibly elsewhere—through stone representation.
