Dualism in the depth-psychology corpus occupies a charged theoretical crossroads: it names a problem that the tradition cannot ignore and yet consistently moves to overcome. Panksepp's neuroscientific survey anchors the modern mind-body form of the debate, tracing it from Cartesian interactionism through contemporary monistic alternatives. Jung himself, as documented in both the 1925 seminar notes and Aion, explicitly resists the dualist label, insisting that his doctrine of opposites is better described as a coincidentia oppositorum — a tension that seeks wholeness rather than irreconcilable bifurcation. McGilchrist extends this argument philosophically, warning against both the collapse into monism and the frozen stand-off of strict dualism, proposing instead a living dialectic of opposites that fulfil one another. Gnostic scholarship (King) complicates received typologies by questioning whether anticosmic dualism is truly the essential signature of Gnostic thought. Eastern voices — Suzuki's Zen and Bryant's Yoga-Sāṃkhya commentary — offer the nondual as a corrective frame, while Masters draws a developmental distinction between the neonate's pre-dual unity, the adult's necessary immersion in duality, and the sage's transcendence of it. Thompson introduces a further variant — informational dualism — as a hidden metaphysical commitment within cognitive science. What unifies these otherwise divergent treatments is the shared conviction that naive dualism forecloses precisely the integrative understanding that depth psychology exists to provide.
Most neuroscientists, who ascribe to monistic beliefs, now believe this is the case. Many others, who hold dualistic worldviews, do not agree. They believe mind and brain are fundamentally different
Panksepp maps the contemporary scientific debate, distinguishing radical mind-brain dualism from interactionist variants and tracing both to the Cartesian legacy.

my leanings are therefore towards the very reverse of dualism
Jung explicitly disavows the dualist label by appeal to the self as a complexio oppositorum, insisting his doctrine of opposites aims at unity rather than irreconcilable bifurcation.

The sage has transcended dualism, whereas the newborn has yet to enter it, not having awakened to the fact that he or she has been born into a realm of deeply ingrained dualism
Masters articulates a developmental typology in which dualism is a necessary stage between pre-personal fusion and post-personal transcendence.

Some philosophies tend to collapse into the monism that opposites are identical; others into the dualism that opposites remain irreconcilable and are merely, at most, juxtaposed.
McGilchrist positions dualism as one of two philosophical failures flanking the authentic insight that opposites co-inhere and mutually generate one another.

radical anticosmic dualism is said to be a fundamental and essential characteristic of Gnosticism. But this characterization is problematic, in part because of the fluidity and imprecision with which the term 'dualism' itself is used
King interrogates the scholarly typology of Gnostic dualism, arguing that the term is deployed with insufficient precision and that Nag Hammadi evidence resists the standard characterization.

as a group, Gnostic texts do not supply consistent evidence of the extreme anticosmic dualism for which they so often stand as the most famous example in Western history
King concludes that the breadth of Nag Hammadi material undermines any monolithic identification of Gnosticism with radical anticosmological dualism.

the notion of information is that it almost invariably goes hand in hand with a dualism of matter versus information. This dualism obscures the nature of cellular dynamics.
Thompson exposes an unacknowledged informational dualism embedded in computational and genocentric biology, arguing it distorts the autopoietic reality of living systems.

Here is Dennett's version of informational dualism: If you think of yourself as a center of narrative gravity an abstraction defined by the brain's information processing
Thompson identifies a form of substance dualism re-emerging in Dennett's computational theory of self, where the informational program is held separable from its physical substrate.

If you take the pairs of opposites you are almost supposing two parties at war with one another—this is a dualistic conception. Ambivalence is a monistic conception; there the opposites do not appear as split apart, but as contrasting aspects of one and the same thing.
Jung distinguishes his own concept of ambivalence from dualism proper, defining the former as a monistic recognition of opposing aspects within a single psychic reality.

When the mind rests serene in the oneness of things, The dualism vanishes by itself.
The Zen verse presents the dissolution of dualism not as a philosophical argument but as the natural consequence of the mind's direct resting in non-discriminative awareness.

Zoroastrian dualism can be clearly distinguished from Gnostic dualism. By portraying the two opposing principles, Ohrmazd and Ahriman, as twin sons of a common father, the Infinite, Zoroastrianism actually resolved its dualism into a monistic solution.
King shows that the comparative category of dualism fractures on close inspection: Zoroastrianism and Gnosticism represent structurally distinct metaphysical positions despite both being labelled dualist.

the coincidentia oppositorum involves both the union and separation of good and evil. It is not possible to get round that.
McGilchrist invokes Jung's coincidentia oppositorum to argue that even ethically, a genuine synthesis must preserve rather than dissolve the tension between the poles.

the opposition between man and animal, which is erected into a dualistic principle, originates within the somatopsychic opposition itself
Simondon traces the philosophical dualism between man and animal back to a more primary psychosomatic polarity, suggesting that metaphysical dualisms are derivative of ontogenetic tensions.

if the opposing forces in lyre or bow simply annulled one another, the string would go slack – no 'tonus' – and nothing, no flight of notes, no arrow's flight – could come from either.
McGilchrist uses the metaphors of lyre and bow to argue that the productive power of opposites requires their maintained tension, not their cancellation or mere juxtaposition.

The libido as an energetic phenomenon contains the pairs of opposites, otherwise there would be no movement of the libido.
Jung grounds the pairs of opposites in libido theory, arguing that psychic energy itself presupposes a polar structure rather than a fixed dualist partition.
