The stomach in the depth-psychological corpus occupies a position at the intersection of somatic reality, symbolic meaning, and psychological process. It is not treated as merely a digestive organ but as a site where psyche and body negotiate their claims upon one another. Classical sources — Cicero's anatomical description, Plato's Timaeus — establish the stomach as a receptacle whose structure and function bear philosophical weight, while John Climacus frames it as a moral-ascetic adversary, the belly's demon, allied with the spirit of fornication. In the modern tradition, the stomach becomes a locus of memory and trauma: the Adult Children of Alcoholics literature positions it as the repository of somatic PTSD, retaining hunger-terror long after the originating events have passed. Bosnak uses it as a precise topographic marker in embodied imagination work, while Barrett locates stomach 'knots' within predictive brain construction of emotion. Neurobiological voices — Levine, Porges, Damasio — situate the stomach within the enteric nervous system and vagal circuitry, treating it as a relay station between gut-brain and cranial-brain communication. Von Franz invokes it clinically and metaphorically: stomach ulcers appear as the somatic consequence of weak ego psychology. Across all positions, the stomach serves as evidence that psychological process is never contained above the neck.
the spirit of fornication, that ally of the stomach's demon, comes — 'Get him now! Go after him. When his stomach is full, he will not put up much of a fight.'
Climacus personifies the stomach as the seat of a demonic force that, when satisfied, weakens spiritual and moral resistance, making appetite the primary adversary of ascetic discipline.

The memory resided in her mind and stomach. As a 30-year-old woman, she shopped for canned potatoes... 25 years after the original incident, this woman's body, her stomach, remembered that hunger pain.
The stomach is presented as a somatic archive of traumatic memory, capable of retaining and transforming PTSD-encoded experience across decades independently of conscious recall.

Its predictions caused my thumping heart, my flushed face, and the knots in my stomach. They directed me to cry, an action that would calm my nervous system.
Barrett identifies stomach sensations as predictively constructed outputs of the brain's emotion-making process rather than passive readouts of physiological states.

Below the gullet lies the stomach, which is constructed as the receptacle of food and drink... The stomach performs a number of remarkable operations; its structure consists principally of muscular fibres.
Cicero establishes the stomach's architectural and functional primacy within the body's design, framing its complex musculature as evidence of purposive natural construction.

there do not exist anorexies brought about by disturbances of the organic sensibility... above all losses of the sensation of hunger... anesthesia of the stomach.
Janet critically examines the hypothesis that hysterical anorexia arises from gastric anesthesia — an abolition of hunger sensation — situating the stomach at the center of the psychosomatic debate in hysteria theory.

Where in her body is the rigidity most held? 'Stomach.' 'Sense the rigidity in the stomach.' Pause. 'And the shoulders.'
Bosnak uses the stomach as a precise topographic anchor in embodied imagination work, treating it as a discrete location within the body's 'memory theater' of trigger impulses.

If you eat completely wrong and your stomach consequently does not react properly, you can say one of two things: either that there is something wrong with the stomach or that you have been eating badly.
Von Franz deploys the stomach as an analogical model for the ego-Self relationship, arguing that psychopathology may originate in ego attitude rather than in a defective Self.

our guts apparently have more to say to our brains (by a ratio of 9:1) than our brains have to say to our guts!
Levine establishes the neurobiological primacy of gut-to-brain signaling via the vagus nerve, repositioning the stomach-gut complex as an active cognitive participant rather than a passive digestive organ.

although SUD and OUD did not show heightened ratings of stomach sensations, both groups displayed lower dorsal dysgranular insula activation than CTL.
Stewart demonstrates that substance use disorder is associated with blunted neural response to stomach interoception, implicating the insula-stomach signal pathway in addiction-related interoceptive dysfunction.

the gastrointestinal tract and the enteric nervous system play an important role in feeling and mood... the 'global' experience of grades of well-being, for example, is importantly related to enteric nervous system function.
Damasio locates the stomach-gut system within the enteric nervous system's contribution to feeling, mood, and the global sense of well-being, extending somatic participation in emotional life.
