Free Energy Principle vs Strawson’s Panpsychism
Friston’s free-energy principle and active inference and Strawson’s Panpsychism Theory, compared field by field from their entries in the Atlas.
At a glance
- Free Energy Principle belongs to the Materialism family in Kuhn's Landscape of Consciousness, Strawson’s Panpsychism to Panpsychism.
- Free Energy Principle treats consciousness as emergent; Strawson’s Panpsychism treats it as fundamental.
- They give the same kind of answer on AI consciousness, life after death and mind uploading.
- On meaning and purpose, Free Energy Principle says “Humanistic only” and Strawson’s Panpsychism says “Uncertain”.

The claim
In brief
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.
Strawson’s PanpsychismStrawson argues that any philosopher taking a realistic view of physicalism must accept that all physical phenomena are intrinsically experiential or phenomenal, leading to panpsychism (or panexperientialism) as a necessary conclusion of 'Real Materialism'. The existence of conscious experience, being the most certain fact, cannot be denied by genuine physicalism .
What consciousness is
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.
Strawson’s PanpsychismConsciousness (experience) is identified as an intrinsic, non-reducible phenomenal property of all fundamental physical stuff or energy (panexperientialism).
Big questions
Can AI be conscious?Both agree
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.
Strawson’s PanpsychismLikelyIf consciousness is an irreducible property of every elementary physical entity, then AI, being composed of physical matter, should also have inner awareness, provided the combination problem can be solved and micropsychic aspects can be manipulated by advanced technology .
Does consciousness survive death?Both agree
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.
Strawson’s PanpsychismUnlikelyAlthough the world is infused with consciousness, survival requires reversing the complex process of microscopic elements coalescing into macroscopic consciousness, which seems difficult for first-person survival upon brain dissolution .
Could a mind be uploaded?Both agree
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.
Strawson’s PanpsychismLikelyIf consciousness is an intrinsic, regular property of the fabric of reality, advanced technology could potentially learn the regularities needed to aggregate or manipulate micropsychic forces to duplicate or upload consciousness .
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.
Strawson’s PanpsychismUncertainPanpsychism is positioned between Materialism (no ultimate purpose) and Dualism/Idealism (ultimate purpose), suggesting possible ultimate meaning/purpose/value .
Nature of mind
Ontology
Free Energy PrinciplePhysicalism; often referred to as Markovian Monism, which views mind/matter distinction as dialectical rather than ontological.
Strawson’s PanpsychismRealistic Monism / Real Materialism
Mind and body
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.
Strawson’s PanpsychismIdentity Theory (Strong Sense). Mental phenomena are considered concrete physical phenomena because real physicalism encompasses all real phenomena, including experience.
Fundamental or emergent
Free Energy PrincipleEmergent
Strawson’s PanpsychismPrimitive/Fundamental
Qualia
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.
Strawson’s PanpsychismQualia are real, concrete, and physical properties of the world; their denial is considered the 'silliest claim ever made'.
How it works
Mechanism
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.
Strawson’s PanpsychismThe principle that all concrete phenomena are physical, combined with the fact that experience is a concrete phenomenon and cannot radically emerge, dictates that experience is intrinsic to fundamental physics.
Where it is
Free Energy PrincipleLocalized in the physical brain system; cortical responses are seen as the brain’s attempt to minimize free energy.
Strawson’s PanpsychismUbiquitous, associated with every part or aspect of physical reality, akin to fundamental fields and particles .
What it does
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.
Strawson’s PanpsychismConsciousness, being physical, fits unproblematically into the natural world. (The specific causal role of individual experiences is implied through their physical status but not detailed in the sources).
Evidence and criticism
Testability
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.
Strawson’s PanpsychismConceptually testable. It is a metaphysical proposal derived from philosophical premises about the nature of the physical world. Nagasawa notes that panpsychism, even if true, may reach a 'cognitive dead end' because it cannot be proven .
Tests so far
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.
Strawson’s PanpsychismNot stated
Criticisms
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.
Strawson’s PanpsychismWidely held to be 'absurd' by some critics . It suffers from the combination problem, requiring an explanation of how micro-level experiences aggregate to yield macrophenomenal properties.
