Chalmers’s Panpsychism vs Spira’s Non-Duality
Chalmers’s Panpsychism and Spira’s Non-Duality, 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, Spira’s Non-Duality to Idealism.
- Both treat consciousness as fundamental.
- On AI consciousness, Chalmers’s Panpsychism says “Conditional” and Spira’s Non-Duality says “No”.
- On life after death, Chalmers’s Panpsychism says “Uncertain” and Spira’s Non-Duality says “Yes”.
- On mind uploading, Chalmers’s Panpsychism says “Uncertain” and Spira’s Non-Duality says “Not needed”.
- On meaning and purpose, Chalmers’s Panpsychism says “Uncertain” and Spira’s Non-Duality 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.
Spira’s Non-DualityThis theory proposes that ultimate reality is a single, infinite, and indivisible pure consciousness (non-duality), from which all objects and individual selves derive their apparently independent existence. It asserts that our essential nature, which is this pure consciousness, transcends the limits and destiny of the physical body and mind.
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.
Spira’s Non-DualityConsciousness is identified as the single, infinite, and indivisible reality (pure consciousness) from which all apparent objects and individual selves derive their existence.
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.
Spira’s Non-DualityNoIf consciousness is the singular, non-material ultimate reality, artificial systems (being derived/material objects) cannot achieve true consciousness, only a functional imitation or borrowing of existence from the ultimate reality.
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.
Spira’s Non-DualityYesThe theory explicitly states that our essential nature, being pure consciousness, does not share the limits or destiny of the body and mind, implying survival or continuity beyond biological dissolution.
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.
Spira’s Non-DualityNot neededSince the essential self is fundamentally non-physical, infinite consciousness, digital duplication of the body/mind is unnecessary for the persistence of the essential self.
Chalmers’s PanpsychismUncertainPlacing experience in the basic fabric of nature gives it a cosmic footing, but Chalmers draws no conclusions about meaning or purpose.
Spira’s Non-DualityCosmic/UltimateConsciousness is the foundation of reality ('the nature of reality') and understanding this non-dual essence is the key to achieving ultimate peace and happiness, providing inherent cosmic purpose.
Nature of mind
Ontology
Chalmers’s PanpsychismPanpsychism (Russellian monism)
Spira’s Non-DualityOntological Idealism. The theory posits consciousness as the ultimate, singular, fundamental existent.
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.
Spira’s Non-DualityThe essential nature of the self (consciousness) is held to be independent of the physical body and mind. Physical existence, and all experience, is mediated through the mind, which is derived from the fundamental consciousness.
Fundamental or emergent
Chalmers’s PanpsychismPrimitive
Spira’s Non-DualityPrimitive/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.
Spira’s Non-DualityQualia (multiplicity and diversity of experience) are seen as manifestations or derivations of the underlying singular pure consciousness, borrowing their apparent independent existence from it.
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.
Spira’s Non-DualityNon-Duality, defined by the ultimate identity between the essence of the self and the ultimate reality (pure consciousness).
Where it is
Chalmers’s PanpsychismThroughout physical reality, at the level of its most basic entities.
Spira’s Non-DualityUbiquitous/Cosmic. Consciousness is the underlying reality (single, infinite, indivisible) that pervades and underpins all existence.
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.
Spira’s Non-DualityConsciousness functions as the ontological source of all existence. Achieving the recognition of this pure consciousness is tied to the ultimate goal of finding lasting peace and happiness.
Evidence and criticism
Testability
Chalmers’s PanpsychismConceptually testable
Spira’s Non-DualitySpeculative/Conceptual. The theory relies on philosophical and spiritual recognition of ultimate reality rather than empirical methods based on third-person observation.

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.
Spira’s Non-DualityLike other Idealist theories, it faces the challenge of explaining precisely how the fundamental, non-material consciousness generates or interacts with the apparent physical world and matter.
