Goff’s Panpsychism vs Spinoza’s One Reality
Goff's Panpsychism and Spinoza’s One Reality: Embodied Mind and Graded Consciousness, compared field by field from their entries in the Atlas.
At a glance
- Goff’s Panpsychism belongs to the Panpsychism family in Kuhn's Landscape of Consciousness, Spinoza’s One Reality to Neutral Monism.
- They give the same kind of answer on meaning and purpose.
- On AI consciousness, Goff’s Panpsychism says “Likely” and Spinoza’s One Reality says “Conditional”.

The claim
In brief
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).
Spinoza’s One RealityBaruch Spinoza holds that there is only one substance, God or Nature, known to us under two attributes, thought and extension. A human mind is the idea of an actually existing human body: one and the same thing as the body, conceived under thought. Because every body has a corresponding idea, mind runs through all of nature, and consciousness varies by degree with the complexity and power of the body.
What consciousness is
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.
Spinoza’s One RealityThe mind is the idea of the body, the same individual conceived under the attribute of thought rather than extension. Spinoza does not single out phenomenal consciousness as a category; his interpreters read consciousness as higher-order awareness, cognitive access, power or complexity of thinking, or affective awareness.
Big questions
Can AI be conscious?Differ
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.
Spinoza’s One RealityConditionalSince every body has a corresponding mind whose richness tracks the body's complexity and power, a sufficiently complex artificial body would have a correspondingly rich mind; whether that mind would be conscious in the human sense is contested.
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.
Spinoza’s One RealityNo 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.
Spinoza’s One RealityNo position
Does it give life meaning?Both agree
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.
Spinoza’s One RealityCosmic/UltimateMinds are modes of God or Nature, and freedom lies in understanding the causal order of Nature through more adequate ideas.

Ontology
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)
Spinoza’s One RealitySubstance monism (dual-attribute)
Mind and body
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.
Spinoza’s One RealityMind and body neither interact nor merely correlate; they are one thing under two descriptions. ‘The order and connection of ideas is the same as the order and connection of things’ (Ethics 2p7), so thought is explained only through thought and extension only through extension.
Fundamental or emergent
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).
Spinoza’s One RealityPrimitive
Qualia
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.
Spinoza’s One RealitySpinoza has no explicit theory of phenomenal character. Interpreters reconstruct it from his accounts of sensation, imagination and affect, where an affect is both a change in the body's power of acting and the idea of that change.
How it works
Mechanism
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.
Spinoza’s One RealityPsychophysical identity under parallel attributes: whatever happens in the body as extension happens in the mind as an idea, so no causal bridge between them is needed.
Where it is
Goff’s PanpsychismConsciousness is ubiquitous, permeating the physical world. In Cosmopsychism, the fundamental consciousness is located in the universe as a whole.
Spinoza’s One RealityMentality is everywhere in nature, since all individuals are ‘animate’ in some degree (2p13s). Whether this means every physical thing has phenomenal experience is contested, and Spinoza does not treat God or Nature as one human-like conscious subject.
What it 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.
Spinoza’s One RealityMind never causes bodily motion and body never causes thought. Affects make ideas matter to behavior by increasing, decreasing or fixing the mind's striving, and freedom comes from forming more adequate ideas of the causes acting on us.
Evidence and criticism
Testability
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'.

Criticisms
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.
Spinoza’s One RealityThe identity formula says mind and body are one thing but not what makes the thought side felt. The ideas-of-ideas reading makes every idea conscious, which Bennett called absurdly excessive, and LeBuffe notes that a mind's overall power and the power of its ideas can diverge, giving odd verdicts on degrees.
