Adaptation occupies a peculiarly charged position in the depth-psychology corpus: it is simultaneously a biological necessity, a psychological task, a potential trap, and a diagnostic criterion for health or pathology. Jung provides the most architecturally elaborated treatment, distinguishing rigorously between adaptation to outer conditions and adaptation to inner conditions — to the unconscious — and insisting that neurosis is precisely a disturbance of one or both processes. For Jung, adaptation is never a static achievement but a continuous energic task, inseparable from the progression and regression of libido. Thompson and the enactivist tradition, drawing on Maturana and Varela, reframe adaptation not as optimization but as a conserved invariant of autopoiesis — the minimal condition of being alive rather than a measure of fitness. Simondon presses further, arguing that adaptation is merely a special case of individuation and therefore insufficient as a criterion for life. Winnicott positions maternal adaptation as the ontogenetic ground of selfhood, with graduated failures of adaptation paradoxically enabling ego development. Fromm resists behaviorist accounts that reduce psychological change to adaptive habit-formation, insisting on an irreducible dynamic core. Across these voices, a persistent tension obtains between adaptation as conformity to the given — socially, biologically, collectively — and adaptation as the creative, individuating response to inner demands that cannot be reduced to mere environmental fit.
Psychological adaptation consists of two processes: 1. Adaptation to outer conditions. 2. Adaptation to inner conditions... In neurosis the adaptation process is disturbed, or rather we might say that the neurosis is itself a disturbed or diminished process of adaptation
Jung defines adaptation as a dual process — outward and inward — and identifies neurosis as the structural failure of either dimension of this process.

Progression could be defined as the daily advance of the process of psychological adaptation. We know that adaptation is not something that is achieved once and for all... the achievement of adaptation is completed in two stages: (1) attainment of attitude, (2) completion of adaptation by means of the attitude.
Jung links adaptation directly to libidinal progression, arguing it is a perpetually renewed process requiring both attitudinal orientation and its concrete fulfillment.

Central to evolution is not the optimization of adaptation, but rather the conservation of adaptation... The adaptation of a living being to its environment is therefore a necessary consequence of its autonomy and structural coupling.
From an autopoietic standpoint, adaptation is recast as an invariant background condition of all living systems rather than a goal or measure of evolutionary fitness.

For neo-Darwinians, evolution involves the optimization of adaptation through natural selection. From an autopoietic perspective, however, adaptation is an invariant background condition of all life... whereas cognition, in the present context, means the activity of sense-making.
Thompson contrasts the neo-Darwinian view of adaptation as optimization with the autopoietic view of adaptation as invariant condition, using this distinction to carve out cognition as something qualitatively beyond mere adaptive fitness.

The relation between subject and object, biologically considered, is always one of adaptation, since every relation between subject and object presupposes the modification of one by the other through reciprocal influence. Adaptation consists in these constant modifications.
Jung grounds the extravert-introvert typology in two biologically distinct modes of adaptation, locating psychological character in the organism's fundamental adaptive strategy.

The good-enough 'mother'... is one who makes active adaptation to the infant's needs, an active adaptation that gradually lessens, according to the infant's growing ability to account for failure of adaptation and to tolerate the results of frustration.
Winnicott frames maternal adaptation as the ontogenetic foundation of psychological development, with the gradual withdrawal of perfect adaptation serving as the productive condition for the child's autonomous ego-formation.

Adaptation, the particular case in which the disparation pair includes an element of the subject and a representative element of the external world, is an insufficient criterion for providing an account of life. Life includes adaptation, but for there to be adaptation, th
Simondon subordinates adaptation to the broader ontogenetic process of individuation, arguing that adaptation is a derivative special case rather than the primary criterion of living being.

regression confronts consciousness with the problem of the psyche as opposed to the problem of outward adaptation... regression leads to the necessity of adapting to the inner world of the psyche.
Jung argues that psychic regression, though apparently a failure of outer adaptation, serves the compensatory function of redirecting adaptive energy toward the demands of the inner world.

If adaptation to the outer world is neglected, the value of the inner world will gradually increase, and this shows itself in the irruption of personal elements into the sphere of outer adaptation.
Jung illustrates through a clinical vignette how one-sided outer adaptation generates compensatory pressure from the inner world, with potentially catastrophic consequences when the domains are conflated.

Individuals can become neurotic when they are unable to find the right position between the two, e.g. not having a desired level of adaptation to the context, or being unfulfilled by it because of an inner disposition.
Myers uses Jung's hydrometer metaphor to show that neurosis arises from failure to achieve a dynamic equilibrium between inner and outer adaptive demands, not simply from environmental mismatch.

The concept of adaptation in Darwinism, however, is not so much that of a state, but a process—the process of adapting or becoming adapted, which is linked to fitness (i. e., to survival and reproduction).
Thompson surveys the received Darwinian account of adaptation as dynamic process rather than static state, providing the conceptual baseline against which enactivist revisions are developed.

Common to all these theories is the assumption that human nature has no dynamism of its own and that psychological changes are to be understood in terms of the development of new 'habits' as an adaptation to new cultural patterns.
Fromm critiques behaviorist and sociological reductionism for dissolving human nature into mere adaptive habit-formation, arguing that a dynamic depth psychology must resist this flattening.

When the stage of elucidation has been traversed, the patient is left with the task of making a new adaptation to life. The old habits of idealization and childish wishful thinking
Stein situates adaptation as the practical task that follows the analytic work of elucidation, marking the transition from insight to functional re-engagement with life.

The point at which external (alloplastic) control is completely abandoned and inner adaptation sets in (whereby reconciliation even with the destruction of the ego, that is, death as a form of adaptation, becomes conceivable) will be perceived inwardly as deliverance.
Ferenczi radically extends the concept of adaptation to encompass autoplastic inner transformation and even the acceptance of annihilation, revealing adaptation's most extreme intrapsychic reaches.

'The length of the human life span,' Dr. Selye commented, 'appears to be primarily determined by the amount of available adaptation energy.'
Drawing on Selye's stress research, this passage proposes a finite somatic resource — 'adaptation energy' — as the biological substrate limiting the organism's capacity to adapt across a lifetime.
