Within the depth-psychology corpus, 'twilight' operates on at least three distinct registers, each carrying substantial theoretical weight. In its most philosophically ambitious usage — developed most fully by James Hillman — twilight names the primordial condition of psychic life prior to the ego's polarizing thrust: a 'divine primordial half-light' from which both consciousness and unconsciousness are simultaneously generated. Here twilight is not a deficiency but an ontological ground, the paradoxical light of archetypal ambivalence that the candle of ego-consciousness necessarily destroys even as it illumines. In Jung's archetypal phenomenology, the 'twilight consciousness of primitive man' designates the pre-differentiated state of subject-object identity out of which mythological images such as the cosmic egg emerge. A sharply contrasting clinical tradition — most systematically in Bleuler's nosology of the schizophrenias — appropriates 'twilight state' (Dämmerzustand) as a technical diagnostic category: a periodic alteration of consciousness characterized by hallucinatory intrusions, lucid intervals, and interrupted rapport with reality, carrying a relatively favorable prognosis within the overall schizophrenic picture. Eliade introduces a cosmological dimension, where twilight marks the transitional interval — dawn and dusk — connecting the great world-ages of the Hindu Mahayuga cycle. Dōgen's Zen usage, finally, recuperates twilight as the phenomenal analogue of meditative self-illumination: the moment after sunset when returning light makes the whole sky glow. The term thus traverses the clinical, the metaphysical, the cosmological, and the contemplative, and its tensions are irreducible.
Consciousness and the unconscious are created into a polarity at the same moment out of original twilight states; and they are continually being created at the same moment.
Hillman argues that twilight is the archetypal primordial condition from which the very polarity of consciousness and unconscious is simultaneously generated, making twilight not a marginal state but the ontological origin of psychic differentiation.

Neither ambivalence nor twilight consciousness is per se a pathological condition even though, as with anything psychological, they may present pathological forms. Living in ambivalence is living where yea and nay, light and darkness, right action and wrong, are held closely together.
Hillman rehabilitates twilight consciousness as a non-pathological mode of psychic wholeness, directly contesting the clinical tradition that reserves the term exclusively for ego deficiency.

To the twilight consciousness of primitive man it seems as if the egg came out of the womb of the wide world and were, accordingly, a cosmic, objective, external occurrence.
Jung locates twilight consciousness as the pre-differentiated psychic condition of archaic humanity in which subject and object remain undivided, and from which mythological projections such as the cosmic egg spontaneously arise.

5. Twilight State The twilight states, li
Bleuler formally designates 'twilight state' as a distinct clinical syndrome within the schizophrenias, establishing the diagnostic category that would persist throughout twentieth-century psychiatry.

the twilight states may be interrupted by periods of lucidity which, in turn, may last anywhere from a few minutes to several days... Schizophrenic twilight states may also take on some characteristics of the Ganser syndrome.
Bleuler elaborates the clinical phenomenology of schizophrenic twilight states, noting their characteristic alternation with lucid intervals and their occasional resemblance to the Ganser syndrome.

twilight states and certain agitated states do not necessarily signify any advance in the disease and therefore usually leave behind them the status quo ante.
Bleuler assigns twilight states a relatively favorable prognostic significance within the overall schizophrenic course, distinguishing them from other acute syndromes that signal genuine deterioration.

A yuga is preceded and followed by a 'dawn' and a 'twilight' that connect the ages together.
Eliade identifies twilight as the cosmological interval articulating the successive world-ages of the Hindu Mahayuga cycle, giving the term a structural function in the mythology of eternal return.

in the quiet, rather lonely scenery of late autumn twilight people can find a much more profound beauty... turning the light inward and illuminating the self... a description of the sky after sunset.
Dōgen's commentary links the phenomenal beauty of autumn twilight — the light that returns after the sun has set — to the meditative practice of self-illumination, grounding contemplative interiority in a precise natural image.

Jung draws on epileptic twilight states as empirical evidence for the unconscious processes of condensation and symbol formation underlying complex psychopathology.

light were a theft from the penumbra of dawn and twilight, of paradoxical archetypal light... Snuff the candle and the twilight dawn
Hillman frames ego-consciousness as a contraction of a wider archetypal twilight, such that the extinction of ego-light would restore rather than destroy the primordial luminosity.
