The Cartesian Split — the ontological severance of mind from body inaugurated by Descartes’s cogito and elaborated across his Meditations — occupies a structurally pivotal position in the depth-psychology corpus. Damasio’s Descartes’ Error delivers the most direct indictment, naming this ‘abyssal separation’ as the founding error that severed reasoning, moral judgment, and suffering from ‘the structure and operation of a biological organism.’ Evan Thompson, drawing on phenomenology and cognitive science, traces the same divorce between consciousness and life, noting that Descartes paradoxically grounded his dualism in first-person experience yet systematically evacuated the living body from his account of mind. Von Franz approaches Descartes from the Jungian interior, reading his famous dreams as evidence that the unconscious pressed upon him the very feeling problem his rationalism split off. Thompson and Damasio converge on the explanatory gap opened by Cartesian metaphysics — the hard problem of subjectivity — while depth psychologists such as Hillman and Edinger treat the split obliquely, addressing its symptomatic effects: the tyranny of rational intellect over soul-life, the mechanistic dissection of organic wholes. The corpus thus treats the Cartesian Split not merely as a philosophical error but as a culturally installed pathology whose psychic consequences — alienation, disembodiment, the repression of feeling — constitute the negative condition against which much of depth psychology defines itself.
the abyssal separation between body and mind…the suggestion that reasoning, and moral judgment, and the suffering that comes from physical pain or emotional upheaval might exist separately from the body
Damasio identifies the Cartesian Split as the foundational philosophical error: the radical severance of mind from body that divorces higher mental operations from the biological organism that sustains them.

Unlike the Aristotelian concept of soul, Descartes’s new concept of consciousness was radically divorced from the concept of life.
Thompson historicizes the Cartesian Split by contrasting it with Aristotle’s unified soul-life concept, arguing that Descartes’s first-person starting point paradoxically severed consciousness from the living body.

What must be shown, to defeat the Cartesian argument, is that when we try to conceive of our minds without our bodies, or vice versa, we do not succeed in doing that, but instead do something else, which we mistake for it.
Thompson, via Nagel, challenges the conceivability argument underpinning Cartesian dualism, suggesting the zombie thought-experiment enacts a conceptual error rather than a genuine insight into the separability of mind and body.

Body connotes life, a living organism, and is richer in meaning than physical in the Cartesian sense. Drawing on this richness can help us to refine the terms of the explanatory gap.
Thompson argues that replacing the Cartesian category of ‘physical’ with ‘body’ — understood as living organism — reframes the hard problem of consciousness and begins to close the explanatory gap the Split created.

the dream had touched the split-off problem of his feeling and the religious problem of evil…he already sketches, in a nutshell, the actual problem of the man of our time, the heir to that epoch of eighteenth-century rationalism, at the dawn of which Descartes stands
Von Franz reads Descartes’s own dreams as psychic evidence that the unconscious confronted him with the very feeling and wholeness problems his rationalism institutionalized as the Cartesian Split.

Daniel Dennett has written extensively about this concept which he dubbed ‘Cartesian theater,’ and has argued persuasively, on cognitive grounds, that the Cartesian theater cannot exist.
Damasio extends his critique of the Cartesian Split into neuroscience, corroborating Dennett’s argument that no single brain site integrates experience — dismantling the implicit homunculus that dualism requires.

certain people who have nothing but the sharp blade of rational intellect with which to understand their tender and sensitive soul-life. Their self-examination is a perpetual torture of self-dissection.
Edinger implicitly diagnoses the psychic consequence of the Cartesian Split: the dominance of analytical, quantitative consciousness over the feeling soul, figured alchemically as the operation of separatio gone pathological.

the Cartesian representation of individuation precisely identifies the individual with its geometrical limits characterized by its figure…there is a non-Cartesian epistemology…in the sense of what concerns the mode of action of one individual on another
Simondon critiques the Cartesian model of individuation — bounded, contact-only, geometrically defined — as insufficient for field-based, probabilistic, and relational accounts of how individuals constitute and affect one another.
