Chalmers’s Panpsychism vs Kastrup’s Analytic Idealism
Chalmers’s Panpsychism and Analytic Idealism, compared field by field from their entries in the Atlas.
At a glance
- Chalmers’s Panpsychism belongs to the Panpsychism family in Kuhn's Landscape of Consciousness, Kastrup’s Analytic Idealism to Idealism.
- Both treat consciousness as fundamental.
- On AI consciousness, Chalmers’s Panpsychism says “Conditional” and Kastrup’s Analytic Idealism says “No”.
- On life after death, Chalmers’s Panpsychism says “Uncertain” and Kastrup’s Analytic Idealism says “Likely”.
- On mind uploading, Chalmers’s Panpsychism says “Uncertain” and Kastrup’s Analytic Idealism says “No”.
- On meaning and purpose, Chalmers’s Panpsychism says “Uncertain” and Kastrup’s Analytic Idealism says “Cosmic/Ultimate”.

The claim
In brief
Chalmers’s PanpsychismDavid Chalmers argues that consciousness may be a fundamental feature of physical reality, carried by the intrinsic properties of its most basic entities. He treats panpsychism, and its cousin panprotopsychism, as a synthesis of materialism and dualism, and holds that it would become the most promising answer to the mind-body problem if someone solves the combination problem.
Kastrup’s Analytic IdealismAnalytic Idealism is a consciousness-only ontology asserting that phenomenal consciousness is fundamental, the singular primitive of reality. Everything else in nature, including the physical world and individual minds, is grounded in patterns of excitation or expressions of this spatially unbound cosmic consciousness.
What consciousness is
Chalmers’s PanpsychismChalmers identifies consciousness with the intrinsic properties of fundamental physical entities, the categorical bases of the dispositions that physics describes. Physics tells us what basic entities do; on this view, phenomenal or protophenomenal properties are what they are.
Kastrup’s Analytic IdealismConsciousness is identified as the singular, spatially unbound, fundamental ontological primitive (cosmic consciousness).
Big questions
Can AI be conscious?Differ
Chalmers’s PanpsychismConditionalSince every physical system has phenomenal or protophenomenal properties at its base, an AI is built from the same ingredients as a brain. Whether it forms a unified conscious subject depends on how the unsolved combination problem is answered.
Kastrup’s Analytic IdealismNoKastrup suggests conscious AI is a fantasy, arguing that consciousness is not reducible to computation or information processing that current computers perform. Consciousness is tied to fundamental phenomenal reality, not hardware function.
Chalmers’s PanpsychismUncertainThe fundamental properties outlast any body, but nothing in the view says whether the particular combined subject survives once the brain's structure breaks down.
Kastrup’s Analytic IdealismLikelyBodily death is predicted to result in the cessation of the local boundary (dissociated alter), causing conscious inner life to expand back into the underlying universal consciousness. This is supported circumstantially by reports of near-death experiences (NDEs).
Chalmers’s PanpsychismUncertainAn upload would be made of the same fundamental properties, but whether it reconstitutes the same subject turns on the unsolved combination problem.
Kastrup’s Analytic IdealismNoConsciousness is not an algorithm or software program reducible to physical structure; therefore, uploading neural patterns (simulated continuation) would only result in a functional duplication ('deep fake') lacking true subjective experience.
Chalmers’s PanpsychismUncertainPlacing experience in the basic fabric of nature gives it a cosmic footing, but Chalmers draws no conclusions about meaning or purpose.
Kastrup’s Analytic IdealismCosmic/UltimateAs consciousness is ultimate reality, existence is fundamentally grounded in mind/awareness, intrinsically providing meaning and purpose rooted in the singular, fundamental consciousness.

Ontology
Chalmers’s PanpsychismPanpsychism (Russellian monism)
Kastrup’s Analytic IdealismIdealism (Modern analytic metaphysics)
Mind and body
Chalmers’s PanpsychismMind and matter are two sides of one fundamental stuff that has both physical and phenomenal properties. Chalmers places this ‘monism’ in the sixth of his six classes of views, the nonreductive ones that expand or reconceive physical ontology.
Kastrup’s Analytic IdealismIndividual minds are dissociated alters of the cosmic consciousness. The inanimate physical world is the extrinsic view of thoughts and emotions within this universal consciousness, meaning a physical world independent of consciousness is a mistaken intellectual abstraction.
Fundamental or emergent
Chalmers’s PanpsychismPrimitive
Kastrup’s Analytic IdealismPrimitive (Fundamental)
Qualia
Chalmers’s PanpsychismQualia are real and irreducible. In the panpsychist version they exist in simple form at the fundamental level; in the panprotopsychist version, basic entities have protophenomenal properties that are not themselves experiences but can ground them.
Kastrup’s Analytic IdealismQualia are intrinsically real and fundamental, constituting patterns of excitation within the fundamental phenomenal consciousness.
How it works
Mechanism
Chalmers’s PanpsychismChalmers reasons dialectically. Materialism (thesis) meets dualism (antithesis) and yields panpsychism; panprotopsychism challenges it and yields Russellian monism; the combination problem then challenges Russellian monism, with no settled resolution yet.
Kastrup’s Analytic IdealismThe principle of dissociation, which localizes the unitary cosmic consciousness into seemingly isolated subjects (alters).
Where it is
Chalmers’s PanpsychismThroughout physical reality, at the level of its most basic entities.
Kastrup’s Analytic IdealismUbiquitous; consciousness is fundamental and spatially unbound. Individual conscious subjects are localized boundary conditions (dissociated alters).
What it does
Chalmers’s PanpsychismBecause phenomenal or protophenomenal properties are the categorical bases of physical dispositions, consciousness sits at the base of physical causation itself.
Kastrup’s Analytic IdealismCausation is grounded in consciousness itself. The inanimate world is the extrinsic manifestation of universal mentation, while the brain serves to constrain or mediate individual consciousness.
Evidence and criticism
Testability
Chalmers’s PanpsychismConceptually testable
Kastrup’s Analytic IdealismSpeculative/Conceptual. Testable primarily by demonstrating the incoherence or lack of parsimony of rival metaphysical theories and by predicting experiential outcomes in extreme states.
Tests so far
Chalmers’s PanpsychismNot stated
Kastrup’s Analytic IdealismCites neuroimaging of psychedelic states (rich experience correlating with reduced brain activity) to critique physicalist theories.
Criticisms
Chalmers’s PanpsychismThe combination problem is the central difficulty, and Chalmers concedes it is unsolved. He also calls panpsychism initially counterintuitive, holding that the sense of oddity fades on reflection.
Kastrup’s Analytic IdealismThe main critical challenge is the 'decomposition problem': explaining how seemingly distinct phenomenal inner lives of subjects can arise within a fundamentally unitary phenomenal field. Also must reconcile the independence of the common external world from personal volition.
