The psyche-soma split occupies a central and contested position across the depth-psychological corpus, functioning simultaneously as a clinical diagnosis, a philosophical problem, and a marker of civilizational pathology. Marion Woodman names the condition explicitly, identifying it as the presenting wound of the majority of her analysands and arguing that any therapeutic approach excluding the body is as one-sided as analysis conducted without dreams. Donald Kalsched grounds the split in the traumatic dissociation of mind from body, tracing the moment when the animating spirit abandons the somatic domain and becomes encapsulated in state-dependent somatic memory. Winnicott contributes the developmental axis: under conditions of insufficient maternal holding, the mind detaches from psychosomatic unity and becomes a 'thing in itself,' a pathological mind-psyche that usurps rather than serves experiential integration. Gilbert Simondon approaches the same phenomenon through a process-philosophical lens, describing individuation as the partial splitting of a prior psychosomatic unity into distinct somatic and psychical domains. Thomas Moore, drawing on Ficino, frames the split as a loss of soul's mediating function between spirit and matter, resulting in the schizophrenic alienation characteristic of modernity. Jung himself refused reduction in either direction, insisting on the psyche's status as anima media natura — a half-bodily, half-spiritual substance irreducible to either pole. The term thus marks the intersection of trauma theory, developmental psychology, phenomenology, and cultural critique.

Since most of my analysands were suffering in one way or another from a deep psyche/soma split, I saw that the exclusion of the body in the exploration of the unconscious was at least as one-sided as would be the exclusion of dreams.
Woodman identifies the psyche-soma split as the constitutive wound of her clinical population and argues that somatic engagement in analysis is as therapeutically necessary as dream work.
Woodman, Marion, Addiction to Perfection: The Still Unravished Bride: A Psychological Study, 1982thesis
When mind and body split, the animating principle of psychological life, or what we would call the spirit leaves. At this point things get more complicated, because the question then becomes, 'Where does the spirit go when it leaves?'
Kalsched identifies the psyche-soma split as the traumatic event through which the spirit is expelled from its embodied ground and subsequently encapsulated in somatic unconscious states.
Kalsched, Donald, The Inner World of Trauma: Archetypal Defences of the Personal Spirit, 1996thesis
We know our trauma patients have been forced to dissociate mind and body and, as a result, they are psychologically depressed and have lost their spirit.
Kalsched frames forced dissociation of mind from body as the clinical core of trauma, with spirit-loss and psychological depression as its direct consequences.
Kalsched, Donald, The Inner World of Trauma: Archetypal Defences of the Personal Spirit, 1996thesis
the underlying idea of the psyche proves it to be a half bodily, half spiritual substance, an anima media natura, as the alchemists call it, an hermaphroditic being capable of uniting the opposites
Jung's formulation, cited by Kalsched, positions the psyche as an intermediate substance between body and spirit whose mediating function is precisely what the psyche-soma split destroys.
Kalsched, Donald, The Inner World of Trauma: Archetypal Defences of the Personal Spirit, 1996thesis
it individualizes by splitting into thought and body. Before individualization, psychosomatic unity is a homogeneous unity; after individualization, it becomes a functional and relational unity.
Simondon reframes the psyche-soma split as a structural consequence of individuation itself, distinguishing pathological rupture from the normative partial splitting that preserves psycho-physiological relation.
Simondon, Gilbert, Individuation in Light of Notions of Form and Information, 2020thesis
There is also the question of the mind, which has to be thought of separately, especially in so far as it becomes a phenomenon split off from the psyche-soma (Winnicott, 1949).
Winnicott locates the psyche-soma split in developmental terms, describing the mind's dissociation from psychosomatic unity as a distinct pathological formation requiring separate theoretical treatment.
Winnicott, D W, Playing and Reality, 1971supporting
when they are so far separated from each other, without benefit of the mediating consciousness of soul, then individuals and societies feel alienated and split... That something is soul, ie connecting link between mind and body.
Moore, via Ficino, identifies soul as the mediating third term whose absence produces the split between mind and body experienced as cultural schizophrenia and existential alienation.
Moore, Thomas, The Planets Within: The Astrological Psychology of Marsilio Ficino, 1990supporting
the psyche cannot be reduced to a mere expression of the body, the result of brain chemistry or some such physical process... psyche and body are not coterminous, nor is the one derived from the other.
Stein explicates Jung's non-reductive account of the psyche-body relationship, establishing the theoretical ground against which any notion of split or dissociation must be understood.

Patients with narcissistic disorders use projective defences resulting in a disordered sense of what belongs to whom. This applies to mind and body of self and other and is central to understanding transference and countertransference.
Mizen bridges psychoanalytic and neurological accounts of self-organization to show that disorders of body ownership and psychic agency share a common mechanism, extending the psyche-soma split into clinical neuroscience.

when the spirit becomes 'moist and gross' it sinks into the depths, i.e., gets entangled with the object, but when purged through pain it becomes 'dry and hot' and rises up again
Woodman draws on Jung's alchemical language of spirit and matter to frame the tension between embodiment and transcendence that underlies the psyche-soma split.

Sedgwick's index entry registers the psyche-soma question as a discrete and recognized problem within Jungian psychotherapy, signaling its technical status in the literature.
