Chalmers’s Panpsychism vs Free Energy Principle
Chalmers’s Panpsychism and Friston’s free-energy principle and active inference, 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, Free Energy Principle to Materialism.
- Chalmers’s Panpsychism treats consciousness as fundamental; Free Energy Principle treats it as emergent.
- On AI consciousness, Chalmers’s Panpsychism says “Conditional” and Free Energy Principle says “Yes”.
- On life after death, Chalmers’s Panpsychism says “Uncertain” and Free Energy Principle says “No”.
- On mind uploading, Chalmers’s Panpsychism says “Uncertain” and Free Energy Principle says “Yes”.
- On meaning and purpose, Chalmers’s Panpsychism says “Uncertain” and Free Energy Principle says “Humanistic only”.

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.
Free Energy PrincipleThis theory conceptualizes consciousness as a natural process arising from the minimization of 'free energy,' which is the difference between an organism's internal model (perceptual expectations) and real-time sensory inputs. Consciousness, therefore, functions as the evolved mechanism for simulating scenarios of the world and reducing prediction error to ensure survival and maintain homeostasis.
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.
Free Energy PrincipleConsciousness is identified as a natural process of inference, specifically the internal emergent model that monitors and minimizes the free energy principle (surprise), thereby optimizing the representational capacities of physical/brain systems.
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.
Free Energy PrincipleYesAs a strong materialist theory, if consciousness is fully explained by computational processes of inference and representation minimization, then non-biological systems capable of executing these processes must eventually attain consciousness in principle.
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.
Free Energy PrincipleNoConsciousness is an emergent natural process tied directly to the functional dynamics and physical substrate of the biological brain; thus, it cannot survive bodily decay.
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.
Free Energy PrincipleYesSince consciousness is understood as an emergent, formalized process of inference optimization, perfect duplication of the brain's information processing and representational dynamics in a non-biological medium should be sufficient for the continuation of the mental 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.
Free Energy PrincipleHumanistic onlyThe foundational imperative of the conscious process is survival (minimizing surprise/maintaining homeostasis). The theory does not rationalize ultimate cosmic meaning or purpose, aligning with general materialist perspectives.
Nature of mind
Ontology
Chalmers’s PanpsychismPanpsychism (Russellian monism)
Free Energy PrinciplePhysicalism; often referred to as Markovian Monism, which views mind/matter distinction as dialectical rather than ontological.
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.
Free Energy PrincipleMonistic/Identity. The theory proposes that consciousness is the natural outcome of the physical/brain system's self-organizing processes, dissolving familiar dialectics between mind and matter.
Fundamental or emergent
Chalmers’s PanpsychismPrimitive
Free Energy PrincipleEmergent
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.
Free Energy PrincipleThe theory is highly deflationary regarding the Hard Problem, treating consciousness as a process to be understood rather than a 'thing' whose qualitative attributes need definition. Qualia, if acknowledged, would be epiphenomena or aspects of the internal generative model required for inference.
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.
Free Energy PrincipleThe Free-Energy Principle (FEP), which states that all self-organizing systems must minimize free energy (or 'surprise'), driving action and perception through active inference.
Where it is
Chalmers’s PanpsychismThroughout physical reality, at the level of its most basic entities.
Free Energy PrincipleLocalized in the physical brain system; cortical responses are seen as the brain’s attempt to minimize free energy.
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.
Free Energy PrincipleConsciousness serves an adaptive and functional role as the evolved mechanism for simulating scenarios, monitoring, and minimizing free energy to promote survival (homeostasis) and navigate the world.
Evidence and criticism
Testability
Chalmers’s PanpsychismConceptually testable
Free Energy PrincipleConceptually and empirically linked to testable models (e.g., in neurobiology and psychology) through its reliance on formalizing representational capacities of physical systems.
Tests so far
Chalmers’s PanpsychismNot stated
Free Energy PrincipleThe principles of FEP form the basis for models utilized in empirical work concerning altered states (e.g., the Entropic Brain Hypothesis under psychedelics) and related theories of perception and cognition.
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.
Free Energy PrincipleCriticized for being highly deflationary and difficult to reconcile with the first-person reality of phenomenal experience (the Hard Problem), viewing consciousness merely as a mathematical process or 'natural outcome.' Friston finds engaging with the philosophical premise of consciousness as a 'thing' difficult.
