The claim
In brief
Bentley Hart’s MonismThis is a metaphysical theory that constructs an ultimate unified monism by asserting the profound inseparability of consciousness (mind) and being (existence) itself. It posits that ultimate reality is God, who is the absolute unity of consciousness and being, fundamentally rejecting reductive physicalist explanations.
FunctionalismFunctionalism posits that mental states are defined by their causal relations to one another, to sensory inputs, and to behavioral outputs, independent of the physical medium (substrate) in which they are realized. The essence of consciousness is determined by how mental states function or operate, rather than by what they are materially composed of.
What consciousness is
Bentley Hart’s MonismConsciousness and being (existence) are two inseparable aspects of a single, ultimate ontological reality.
FunctionalismMental states are identified as functional states, constituted by their causal relations, roles, results, and outputs, implying they are realizable in any substrate that supports those functions.
Big questions
Can AI be conscious?Differ
Bentley Hart’s MonismNoConsciousness is a restricted instance of infinite mind (God) and is not reducible to computation or physical processing. Therefore, artificial systems based purely on physical mechanisms cannot instantiate true consciousness.
FunctionalismYesFunctionalism holds that consciousness is based on function, not biology. If the correct functions can be realized computationally in non-biological substrates, AI consciousness is possible in principle and certain if Materialism is true.
Bentley Hart’s MonismYesConsciousness is identified with ultimate being and God, meaning it is fundamental and cannot be destroyed. Hart’s theology suggests individuals are destined for union with God, becoming 'uncreated'.
FunctionalismConditionalAs a physicalist theory, consciousness is tied to the substrate. Survival beyond death of the biological body is only possible if the functional mental state can be successfully transferred (uploaded) to a new, continuing substrate (virtual immortality).
Bentley Hart’s MonismNoConsciousness is metaphysically unified, physically infrangible mental agency , making it impossible to capture, duplicate, or upload via computational means, which would only replicate 'third-person' processes.
FunctionalismLikelyFunctionalism serves as the theoretical basis for virtual immortality. If the functional role of the mental self can be perfectly duplicated and uploaded to a new medium, the first-person mental self is preserved.
Bentley Hart’s MonismCosmic/UltimateThe entire reality is rationally coherent and grounded in God, the ultimate reason and consciousness, inherently supplying ultimate meaning, purpose, and value.
FunctionalismHumanistic onlyFunctionalism describes the mechanism by which mind/consciousness operates within a physical world, providing capacities for agency and reflection, but offers no rationale for ultimate cosmic meaning or teleology, aligning with the general stance of Materialism.
Nature of mind
Ontology
Bentley Hart’s MonismIdealist Monism/Theistic Monism
FunctionalismPhysicalism (broadly, agnostic to substance). The theory is classified under Materialism, but it is metaphysically agnostic regarding nonphysical substances, focusing primarily on the functional description of mental states.
Mind and body
Bentley Hart’s MonismNon-reductive correlation/Theistic interaction (Justification: Hart argues the causal descriptions of material and mental spheres are radically disparate and incommensurable, making reductionism incoherent. Interaction, while problematic for materialists, is possible, perhaps through the power of God).
FunctionalismMental states are functional states identical to the functional roles that are realized or instantiated in a physical substrate, leading to 'functional state identity theses'.
Fundamental or emergent
Bentley Hart’s MonismPrimitive
FunctionalismEmergent. Consciousness arises from the functional organization realized by a sufficiently complex substrate (like neural tissue or computer chips).
Qualia
Bentley Hart’s MonismQualitative aspects of experience (mental reality) are irreducible. The irreducibility of mind is the same as the irreducibility of being, suggesting qualia are grounded in ultimate intelligibility.
FunctionalismThe theory traditionally struggles to account for phenomenal qualia, often addressing them by asserting that the qualitative feel is entirely exhausted by the functional role, or by coupling with representational theories.
How it works
Mechanism
Bentley Hart’s MonismThe unification of the conditions for knowledge (mind) and the conditions for existence (being) into a single, simple, ultimate act or reality (God).
FunctionalismThe principle of multiple realizability, stating that mental state realization is independent of the physical substrate, contingent only upon the required function being instantiated.
Where it is
Bentley Hart’s MonismUbiquitous/Cosmic (Justification: Consciousness, being unified with ultimate Being/God, is the ground of all reality, aligning with Idealist metaphysics).
FunctionalismDistributed wherever the functional organization is successfully realized, regardless of whether the substrate is neural tissue or hardwired computing components.
What it does
Bentley Hart’s MonismMind holds causal priority over matter. Conscious, unified mental acts depend upon the infinite mind (God). The theory rejects the causal closure of the physical.
FunctionalismFunctions, roles, and outputs are dispositive. Mental states are causally effective because they are defined by their causal relations within the system (functional role).
Evidence and criticism
Testability
Bentley Hart’s MonismSpeculative/Conceptually Testable (Justification: The theory is a high-level metaphysical framework founded on philosophical critiques; Hart questions the possibility of a science of mental reality under physicalist assumptions).
FunctionalismConceptually and empirically testable. Thought experiments (like substrate replacement) probe its conceptual limits, and computational realization (AI) tests its empirical application.
Tests so far
Bentley Hart’s MonismNot stated
FunctionalismThe silicon chip replacement thought experiment is used conceptually to test whether phenomenal consciousness is preserved when the functional role is maintained across a change in substrate.
Criticisms
Bentley Hart’s MonismCritics find the conclusion to unify consciousness, being, and God 'strange'. The theory faces the standard challenge of articulating the continuity or interaction between the disparate mental and material spheres without invoking rejected concepts like strong emergence.
FunctionalismIt is criticized heavily for failing to account for phenomenal consciousness (qualia) by describing only the functional role, leading to the 'hard problem' challenge that functional roles may not exhaust the nature of conscious experience.
