The Hard Problem of Consciousness in 2026

Three physicalist proposals, three different explanatory locations

Dennis Nicholson: perspectival physicalism

In The Hard Problem of Consciousness Resolved (August 2026), Nicholson proposes that a conscious experience and the corresponding brain state can be a single physical reality known from incompatible first-person and third-person perspectives. Direct knowledge is epistemologically irreducible to an external observer's knowledge without entailing a second substance or a second occurrence. This is a substantive answer to the apparent explanatory gap, and Nicholson's related published argument predates 2026.

The central question is the transition from one reality could be differently known to experience and this physical state actually are identical. Distinct perspectives make identity intelligible; they do not by themselves establish it. His discussion of scientific mapping offers a research programme, but mapping and correlation are also compatible with some rival interpretations. This is a question of justification, not a dismissal of Nicholson's proposal.

Paul G. Skokowski: sensory naturalism

Skokowski's 2022 paper Sensing Qualia develops grounded functionalism, and his 2026 book develops the sensory-naturalist approach. The senses are natural physical detectors whose contents concern properties of the world: surface reflectances, temperatures, chemical properties and, in the pain discussion, damage detected by sensory pathways. His proposal takes those detected properties seriously as the contents of sensation rather than inventing a second phenomenal realm.

This theory is especially clear about veridical perception and the role of environmental properties. Its difficult cases are nonveridical sensations, where an experience occurs without the represented object or property. Skokowski does address misrepresentation: the challenge is not to pretend that he ignores dreams or hallucinations, but to assess whether a detector's mistaken representation adequately explains their vivid sensory character.

Victor Wyld: two-tier Ownership Answer

Wyld's October 24, 2026 philosophical paper proceeds in two tiers. Tier One challenges the move from an explanatory or conceptual gap to a necessary additional phenomenal property, intrinsic phenomenal nature, or bridging law. Tier Two offers a positive sensory-identity thesis: hurting is the sensory occurrence itself, not an added feeling manufactured by that occurrence.

Objective Ownership means that an occurrence belongs to whatever is implicated in it; the relation precedes and does not require awareness. The occurrence may implicate a non-biological object without implying that object is sentient. Sensation concerns what is sensed and the character of that sensory occurrence. Consciousness requires scrutinized awareness. These are distinct explanatory relations, not three stages that generate qualia.

The comparison under IBE

An abductive verdict should compare explanatory scope, integration with relevant physical evidence, ontological commitments, and remaining costs. Merely assigning a favourable name or rating to a theory is not an explanation. The following table states the comparative case advanced here.

Why phantom pain, dreaming and hallucination matter

An account of sensation must contend with experiences in which apparent sensory content does not track an actual external object or its apparent bodily location. Phantom-limb pain is painful without damage occurring in a present limb at the experienced location; dreams and hallucinations can exhibit vivid colour or sound without the corresponding object in the environment.

These cases do not automatically refute externalist theories: a detector may misrepresent, and Skokowski explicitly allows for that. The comparative issue is whether identifying qualia with externally detected properties explains the phenomenal character of an erroneous detection as well as identifying sensory character with the physically constituted sensory occurrence does.

For Wyld, the physical occurrence of sensing is the proposed bearer of sensory character, whether an external stimulus is correctly represented, wrongly localized, or absent. The occurrence and its represented source must not be conflated. Neural mechanism-dependence, cortical stimulation, and sensory tracking are relevant evidence for this account; they do not deductively prove identity over correlation.

Ontological economy is not a count of conceptual distinctions

It is a mistake to mark an identity theory as ontologically expensive merely because it names Ownership, sensation and scrutiny separately. These terms specify different explanatory jobs. They do not, by themselves, posit new substances, fundamental properties or laws.

An a posteriori identity claim is not the claim that a physical event acquires an additional phenomenal ingredient. A critic may reasonably ask what justifies identifying sensory character with a particular sensory occurrence. That is an epistemic challenge. It is not evidence that the account secretly requires a new psychophysical law or panprotopsychist property.

By the same standard, Skokowski's identification of sensory contents with worldly physical properties is not penalized merely for being an identity proposal. If both theories remain wholly physicalist, the comparative decision turns on explanatory reach and evidential support rather than invented differences in ontological cost. Physical identity is also not automatically analytical functionalism; identity and functional role are distinct claims.

Three distinctions the theory cannot afford to lose

Ownership asks whose occurrence it is. Objective implication can be present when nobody is conscious: a sheet of paper owns its tearing, and a person under anaesthetic owns an amputation without necessarily sensing it. Ownership alone generates neither sensation nor consciousness.

Sensory identity asks what the character of sensing is. Hurting belongs to the painful sensory occurrence; the character is not a further product supplied by an observer, Ownership or a later cognitive operation.

Scrutiny concerns consciousness. In SAT, there is no consciousness without scrutiny. Scrutiny does not manufacture sensory character, and the theory does not require positing a separate neural module or a second temporal stage that injects feeling into a previously neutral occurrence. Carrying concerns implication across continuation, which is again a distinct question.

The strongest questions that remain

Wyld's preference under IBE is not established merely by pointing out that rival proposals face difficult cases. The positive identity must earn its explanatory standing. What evidence distinguishes sensory character is the physical sensory occurrence from a theory in which sensory character is an irreducible property perfectly correlated with that occurrence? Which cases count for and against each identification? And is scrutiny sufficiently specified to distinguish conscious from non-conscious awareness without defining the answer into existence?

Those questions are live philosophical objections. Mechanism dependence, causal participation, sensory tracking and evolutionary fit contribute to Wyld's abductive case, but no one datum independently settles the metaphysics. The relevant question under IBE is whether rival additions explain a fact that the physical sensory occurrence and participant-relative relations cannot explain at comparable cost.

Comparative conclusion

Nicholson offers an important epistemological diagnosis of the gap. Skokowski offers a serious physicalist account of detectable sensory content. Wyld offers a distinct combination: criticism of the inference to additional ontology, sensory identity grounded in the occurrence, objective Ownership independent of consciousness, and a scrutiny criterion for consciousness.

Under the IBE criteria defended here, Wyld's account is preferred because it aims to explain both veridical and nonveridical sensory character while preserving a separate answer to the conscious threshold, without adding a further phenomenal ingredient. That is the substantive reason for the comparative judgment. It is not an assertion that earlier authors had no solutions, that their complete books have been refuted, or that every philosopher agrees.
