Forgetting occupies a remarkably diverse and contested position across the depth-psychological corpus. Far from being treated as mere failure of retention, it emerges as a phenomenon with positive, even constitutive, functions. Freud establishes the interpretive foundation: forgetting is purposive, governed by counter-will and repression, legible in parapraxes, mislaying, and the resistance encountered in dream analysis. Jung elaborates the structural dimension, insisting that what vanishes from consciousness does not cease to exist but persists in an unconscious register awaiting retrieval. Nietzsche, whose shadow falls heavily on this literature, advances the most radical positive claim: forgetting is an active faculty of repression indispensable to psychic health, the precondition of new experience. Hillman imports this Nietzschean-chthonic sense into archetypal psychology, reading the forgotten dream as belonging to Lethe and the underworld — forgetting as the soul's own movement away from ego-service. Estés redeploys the concept clinically, distinguishing conscious forgetting (willful release of obsessive recollection) from erasure of memory. The Platonic-Hillmanian tradition further treats pre-natal forgetting at the plain of Lethe as the ontological ground of incarnate existence. Tensions between these positions — forgetting as symptom vs. faculty, as pathology vs. grace, as loss vs. liberation — make the term a fault-line running through the entire field.
Forgetting is no mere vis inertiae as the superficial imagine; it is rather an active and in the strictest sense positive faculty of repression, that is responsible for the fact that what we experience and absorb enters our consciousness as little while we are digesting it
Nietzsche redefines forgetting as an active, positive psychic capacity—a form of healthy repression that protects consciousness from being overwhelmed by undigested experience.

The forgotten dream is the dream resisting to be remembered, perhaps because memory has been put into the yoke of the dayworld and the forgotten dream refuses this service... dreaming itself, as we said earlier, is a process of forgetting, of removing elements out of life so that they no longer hold such interest
Hillman locates dream-forgetting within an archetypal underworld logic, arguing that dreaming is itself a process of Lethean release from ego-consciousness rather than a failure of recall.

Before the souls enter human life, however, they pass through the plain of Lethe (oblivion, forgetting) so that on arrival here all of the previous activities of choosing lots and the descent from the lap of Necessity is wiped out.
Hillman employs the Platonic myth of Lethe to establish pre-natal forgetting as the ontological condition of incarnation, the ground from which the soul's daimonic calling must be recovered.

We practice conscious forgetting by refusing to summon up the fiery material, we refuse to recollect. To forget is an active, not a passive, endeavor... This kind of forgetting does not erase memory, it lays the emotion surrounding the memory to rest.
Estés articulates a clinical, volitional model of forgetting as active disengagement from obsessive recollection, distinguishing it sharply from the erasure of memory.

forgetting to execute a plan may bear many meanings... when we find proof in a large majority of cases that the forgetting of an intention proceeds from a counter-will, we gain courage to extend this solution to another group of cases
Freud systematizes the purposive character of forgetting across parapraxes, grounding it in an operative counter-will that analysis can identify even when the subject denies it.

When something vanishes from consciousness it does not dissolve into thin air or cease to exist, any more than a car disappearing round a corner becomes non-existent. It is simply out of sight
Jung establishes the fundamental structural argument that forgetting is not annihilation but displacement into the unconscious, where the content persists and may re-emerge.
, The Undiscovered Self: With Symbols and the Interpretation of Dreams, 1957thesis
When something vanishes from consciousness it does not dissolve into thin air or cease to exist... It is merely the decrease of attention that causes its apparent disappearance.
Jung reinforces his structural account of forgetting as attentional withdrawal rather than obliteration, using perceptual analogy to argue for the persistence of unconscious content.

there was a hostile (i.e. resistant) purpose at work in the forgetting of the dream... resistance shows unmistakably in the readiness with which he accepts
Freud identifies the forgetting of dreams as a manifestation of resistance within the analytic process, linking nocturnal amnesia directly to defensive psychic operations.

Another series of such phenomena are those based on forgetting something temporarily, though not permanently; as, for instance, when anyone cannot think of a name which he knows quite well
Freud taxonomizes the varieties of forgetting — temporary, permanent, and selective — as a class of parapraxes revealing unconscious interference in conscious mental functioning.

She had forgotten that this man had been her husband for some weeks... I know a woman now divorced from her husband who, in managing her money-affairs, frequently signed documents with her maiden name
Freud demonstrates through clinical vignettes that forgetting in intimate relationships symptomatically expresses unconscious estrangement, anticipating future rupture.

Confusing forgiving with forgetting sets another trap: We become convinced that mistakes and wrongdoings not only can, but should, be forgotten... The offense is precisely what must not be forgotten, since it is through the act of facing what has happened... that the possibility of atonement occurs.
Kurtz argues that spiritual tradition explicitly distinguishes forgiveness from forgetting, insisting that redemptive memory — not amnesia — is the vehicle of atonement and wholeness.

he found that forgetting had at least two phases: a rapid initial decline that was sharpest in the first hour after learning and then a much more gradual decline that continued for about a month.
Kandel details Ebbinghaus's empirical discovery of the biphasic forgetting curve, providing the neuroscientific baseline against which depth-psychological accounts of motivated forgetting are implicitly measured.

The subjects forgot more than 90% of the syllables after 8 hours of normal waking activity, but only about 44% after 8 hours of sleep.
James presents experimental evidence that forgetting is substantially reduced during sleep, suggesting that waking interference — proactive and retroactive inhibition — accounts for much ordinary forgetting.

The phenomenon of forgetting is actually a normal part of normal motor action... forgetting is normal and possible precisely because motor behavior does not ordinarily require that my limbs be included in my perceptual awareness.
Gallagher extends the concept of forgetting into phenomenology of embodiment, arguing that the transparent functioning of body schemas constitutes a form of beneficial, operative forgetting.

unawareness, or 'the phenomenon of information inaccessibility', may help a child to maintain necessary attachments with abusive caregivers... information can become inaccessible via many routes (e.g., everyday forgetting, encoding failures)
Lanius situates traumatic forgetting on a continuum from ordinary encoding failures through motivated dissociation, arguing that inaccessibility of abuse-related memory can serve an adaptive function in maintaining attachment.

if active attempts are being made to avoid and forget traumatic material, avoidant cognitive processes can become automatic... attention can be withdrawn unconsciously from reminders... thus maintaining traumatic amnesia.
