Eliminative Materialism vs Goff’s Panpsychism
Churchland’s Eliminative Materialism and Goff's Panpsychism, compared field by field from their entries in the Atlas.
At a glance
- Eliminative Materialism belongs to the Materialism family in Kuhn's Landscape of Consciousness, Goff’s Panpsychism to Panpsychism.
- They give the same kind of answer on life after death.
- On meaning and purpose, Eliminative Materialism says “Humanistic only” and Goff’s Panpsychism says “Cosmic/Ultimate”.

The claim
In brief
Eliminative MaterialismPaul and Patricia Churchland hold that common-sense psychology, our everyday talk of beliefs, desires, and experiences, is a radically false theory that a completed neuroscience will displace rather than smoothly reduce. Consciousness as we ordinarily conceive it is a brain-generated picture shaped by evolution, and our self-understanding, introspection included, will be rebuilt in neuroscientific terms.
Goff’s PanpsychismGoff argues that consciousness is a fundamental and ubiquitous feature of the physical world, positioning it as the best hope for solving the hard problem that materialism fails to address. He asserts that the physical sciences, with their purely quantitative language, cannot account for the qualitative nature (qualitivity) or subjective aspect of experience, requiring a change in our fundamental understanding of science (Galileo's Error).
What consciousness is
Eliminative MaterialismWhat we call consciousness, as folk psychology describes it, does not exist in that form. The real phenomena are neural processes, which only a mature neuroscience will describe correctly.
Goff’s PanpsychismConsciousness is identified as a fundamental and ubiquitous feature of the physical world. Specifically, Goff explores Panpsychism through the lens of Russellian Monism, where phenomenal or protomenal properties are the intrinsic nature of fundamental matter.
Big questions
Eliminative MaterialismNo position
Goff’s PanpsychismLikelyIf consciousness is an intrinsic property of matter/energy, then the physical components of AI systems would possess proto-conscious properties. The realization of full AI consciousness would depend on whether advanced technology can resolve the combination problem in the artificial substrate.
Does consciousness survive death?Both agree
Eliminative MaterialismNoSince the mind is the brain, nothing mental survives the brain’s death.
Goff’s PanpsychismUnlikelyWhile consciousness is fundamental, the survival of individual, unified, personal consciousness (the macro-subject) is challenging given the theory relies on a specific organizational structure (the brain) for macro-experience. Success depends on whether the emergent subject persists outside the biological mechanism.
Eliminative MaterialismNo position
Goff’s PanpsychismLikelySince the physical substrate (digital hardware) is composed of fundamentally conscious components (proto-consciousness), virtual immortality is achievable if the conscious organization (solving the combination problem) can be perfectly replicated in the new medium.
Eliminative MaterialismHumanistic onlyPatricia Churchland urges us to see ourselves as organisms in nature, understood by scientific methods, with no cosmic purpose.
Goff’s PanpsychismCosmic/UltimateGoff's Agentive/Teleological Cosmopsychism implies that the universe itself is a conscious mind with goal-directed intent, suggesting an ultimate, cosmic meaning and purpose.
Nature of mind
Ontology
Eliminative MaterialismPhysicalism (eliminative)
Goff’s PanpsychismPanpsychism (often formalized as a variant of Russellian Monism, leading to Hybrid Panpsychism or Agentive Cosmopsychism, where the universe is a conscious agent)
Mind and body
Eliminative MaterialismThe mind is the brain. Patricia Churchland calls her program a ‘unified theory of the mind-brain’ and treats claims that mind goes beyond brain as the residue of folk myths.
Goff’s PanpsychismMind (consciousness/protoconsciousness) is the intrinsic nature of the physical world. This relationship avoids the causal difficulties of Dualism by positing that mental properties are inseparable from the physical fabric, aligning with extended materialism.
Fundamental or emergent
Eliminative MaterialismNeither
Goff’s PanpsychismConsciousness is Primitive/Fundamental at the lowest level of reality. However, human subjects of experience are considered Strongly Emergent entities, while their phenomenal properties are Weakly Emergent (Hybrid Panpsychism).
Qualia
Eliminative MaterialismQualia as folk psychology and philosophers conceive them are expected to give way to neuroscientific description; the view treats consciousness as a kind of illusion generated by the brain.
Goff’s PanpsychismQualia (sensory qualities or qualitivity) are fundamental properties of reality and cannot be reduced to the purely quantitative language of physics, which has an inherent explanatory limitation. Panpsychism solves the hard problem by postulating that these qualities exist fundamentally.
How it works
Mechanism
Eliminative MaterialismTheory displacement. Folk psychology will be replaced the way outdated scientific theories were, its principles and ontology discarded rather than mapped onto brain states.
Goff’s PanpsychismThe primary principle is metaphysical necessity: consciousness must be fundamental to avoid the explanatory gap and solve the hard problem. In Agentive Cosmopsychism, teleological causation (goal-directed intent) by the conscious cosmos explains fine-tuning.
Where it is
Eliminative MaterialismIn the brain.
Goff’s PanpsychismConsciousness is ubiquitous, permeating the physical world. In Cosmopsychism, the fundamental consciousness is located in the universe as a whole.
What it does
Eliminative MaterialismBehavior is caused by neural processes; neuroscience is expected to explain it better than folk psychology does.
Goff’s PanpsychismAt the cosmic level (Agentive Cosmopsychism), consciousness functions as an agent explaining cosmic fine-tuning and the emergence of life/mind. For individual subjects, consciousness is the source of value and identity. The combination problem must be resolved to establish coherent causation from micro- to macro-subjects.
Evidence and criticism
Testability
Eliminative MaterialismConceptually testable
Goff’s PanpsychismSpeculative. The theory aims to solve conceptual and metaphysical tensions (like the hard problem) , but the fundamental claim that consciousness is ubiquitous is difficult to test empirically, leading to critiques that panpsychism reaches a 'cognitive dead end'.
Tests so far
Eliminative MaterialismThe view stakes its claim on the future course of neuroscience; whether folk categories survive in mature brain science is the long-run test.
Goff’s PanpsychismNot stated
Criticisms
Eliminative MaterialismCritics say denying subjective experience defies both intuition and direct evidence; Galen Strawson calls the denial of experience ‘the strangest thing that has ever happened in the whole history of human thought’. There is also tension between Patricia Churchland’s talk of reduction to neurobiology and the eliminativist claim that folk psychology will be displaced rather than reduced.
Goff’s PanpsychismThe main tension is the Combination Problem: how do micro-phenomenal properties combine or aggregate to form complex macro-phenomenal properties (such as human consciousness). Goff's rejection of quantitative descriptions being able to capture quality is also critiqued by proponents of information-based theories.
