Within the depth-psychology corpus, 'mortal' operates as far more than a biological descriptor; it names the ontological condition that makes meaning, value, and psychological transformation possible. The range of treatments is striking. For Hillman, mortality is inseparable from the archetypal wound—the Achillean heel that simultaneously grants swiftness and ensures death is the substrate of the human condition itself, not a pathology to be overcome. Peterson, reading Homer through Jung, argues that value is literally forged by mortality's three constraints—permanent loss, radical uncertainty, and utter powerlessness—and that the gods are structurally excluded from this grammar of value-creation. Yalom approaches mortality as the primary existential datum whose denial generates the full spectrum of psychopathology. Campbell and Edinger, drawing on mythological and alchemical sources respectively, treat the mortal/immortal polarity as a dialectical engine: the hero is precisely the hybrid figure who is both, and mortificatio names the alchemical death that precedes quintessential transformation. Plato's Timaeus frames the cosmos itself around this division, with the divine creating immortal principles and delegating mortal bodies to lesser craftsmen. Across these positions, the central tension is whether mortality is a deficit to be transcended or the very precondition of depth, heroism, and soulful existence.
value is not an a priori truth to be discovered but a psychic substance forged under 'Mortality's Three Constraints': permanent loss, radical uncertainty, and utter powerlessness.
Peterson argues that mortality—defined by three structural constraints—is the necessary forge in which value itself is created, and that the gods are grammatically excluded from this process in Homeric epic.

The same foot that made Achilles the 'swiftest' also carried that flaw that made him mortal… Organ inferiority is the human condition, our liability to be bruised at the heel, our mortality.
Hillman identifies mortality not as pathology but as the archetypal substrate of the human condition, inseparable from the very gift that distinguishes each individual.

our mortality and our immortality are one… Castor is mortal and Pollux is immortal. And so are we, both mortal and immortal.
Campbell locates the mortal/immortal polarity at the center of initiatory mythology, arguing that the human being is constitutively both and that recognizing this duality is itself the telos of mythic initiation.

the universe, which was a single animal comprehending in itself all other animals, mortal and immortal. Now of the divine, he himself was the creator, but the creation of the mortal he committed to his offspring.
Plato's Timaeus establishes the cosmological framework in which mortality is delegated by the divine demiurge to lesser craftsmen, making the mortal body ontologically secondary to but dependent upon the immortal principle.

the mortal body from the mortal worms… the incorruptible body that grows out of the death of the corruptible seed. It corresponds to the alchemical idea that death is the conception of the Philosophers' Stone.
Edinger's alchemical reading identifies mortificatio as the psychic process by which the mortal and corruptible is transformed into the incorruptible Self, making mortality the precondition of individuation.

a soul that has been sullied… wanders from the blessed ones for three times countless years, being born throughout the time as all kinds of mortal forms… 'I am delivered, forever, from death, an immortal god revered by all.'
Vernant documents the Greek philosophical tradition, from Empedocles onward, in which the mortal condition is a stage of expiation to be traversed rather than a permanent ontological status.

When death is excluded, when one loses sight of the stakes involved, life becomes impoverished. It is turned into something, Freud wrote, 'as shallow and empty as… an American flirtation.'
Yalom, drawing on Freud, argues that the exclusion of mortality from consciousness impoverishes existence, implying that awareness of one's mortal condition is therapeutically and existentially essential.

Semele was a child of man, who had conceived a son in the arms of the god of heaven. But the mortal mistress did not have the power to endure the fulminating majesty of the god who loved her.
Otto's reading of the Semele myth frames the mortal's inability to sustain divine contact as the necessary tragic precondition for the birth of Dionysus, making mortal limitation constitutive of theogonic creativity.

Thirty thousand, that is, innumerable immortal Watchers over mortal men wander invisibly in the service of Zeus over the earth, taking note of right and wrong.
Rohde traces the Hesiodic conception in which mortal men are defined by their subjection to invisible divine oversight, establishing the mortal/immortal boundary as a cosmological and ethical frontier.

one of the characteristics of the hero is that he is a hybrid between human and divine, and is thus destined to be a pontifex.
Greene articulates the astrological-psychological thesis that the hero's defining attribute is hybrid mortality—being born of one divine and one mortal parent—which positions him as a bridge between the two realms.

there are other mothers for whom the men are mere ciphers… who only appear as the mortal fathers of a mortal twin.
Neumann situates the mortal father as the lesser, cipher-like element in hero mythology, against which the divine or suprahuman maternal principle asserts the hero's transpersonal origin.

The dead, worthless residue is the stuff of the nigredo phase… The worthless becomes the most precious, and the last becomes first. It is the psyche that we find in the worthless, despised place.
Edinger's discussion of the caput mortuum—the mortal residue of alchemical distillation—figures mortality as the paradoxical locus of psychic treasure, where the most despised becomes most precious.

Her childlike concern for the transience of life even though it may seem a 'blight,' is a natural and necessary attribute of mankind – one all too easily outgrown.
Nichols argues, via Hopkins, that genuine mourning over mortality's transience is a necessary and easily suppressed human capacity, whose loss marks psychological impoverishment.

Although death is a concept of fleshly limitation belonging to the yin side of life, it is usually referred to as masculine.
Nichols notes a tension in the gendering of death within archetypal symbolism, observing that the concept of mortal fleshly limitation is typically coded masculine despite belonging to the yin principle.

It is in dealing with death that one is most forcibly made aware of how we have yielded, hands down, to the forgetting of Being.
McGilchrist links the confrontation with mortality to the philosophical problem of the forgetting of Being, positioning death as one of the few remaining sites where modern consciousness might apprehend existence itself.

we must show also that men are mortal in that and in so far as they are men, if we are going to establish the cogency of the proposed inference.
Long and Sedley's presentation of Stoic sign-inference methodology uses universal human mortality as the test case for distinguishing essential from accidental predication in logical argument.
