The Unobjectifiable: Why Phenomenal Consciousness Cannot Be a Variable in Scientific Explanation

This paper argues that the “Hard Problem” of consciousness is a result of a category error: to treat phenomenal consciousness (P), which is fundamentally first-person and unobjectifiable, as an object within relational, third-person frameworks. By clarifying the logical separability of phenomenal consciousness(P) from functional/access consciousness(A) using established literature such as Ned Block’s distinction and the philosophical zombies thought experiment, I then argue methodologically that P cannot function as a variable, property or explanandum in third-person scientific models. The core of this paper is a dual-track critique of any theory attempting to treat P as an object of study. First, through a Wittgensteinian “therapeutic” lens, I demonstrate that much contemporary public discourse around P is sustained by a grammatical confusion. Phenomenal terms (P-talk) do not successfully refer to a private object; rather, they arise as expressive outputs of A encountering the limits of third-person explanation. By revisiting the Beetle in the Box argument, I show that P is fundamentally unobjectifiable: once treated as an object of reference, it ceases to play the role it was meant to capture. Second, I demonstrate that frameworks of science, including the most permissive one, cannot accommodate P. Beyond arguments from publicity and causal closure, I formalize P’s informational inertia within a Bayesian framework. If P is logically separable from A, then P(E|A,P)=P(E|A) for any empirical evidence E. Observable data is thus equally compatible with or without P’s presence. Inclusion of P adds no explanatory power and violates parsimony, rendering it methodologically inert within third-person scientific inquiry. In acknowledging that the failure is not the signal of scientific shortcomings but reveals the category error, I explore the post-analytic implications. I advocate that mind science should focus rigorously on the mechanisms of A; ethics can be grounded in functional and observable criteria without appeal to metaphysically opaque phenomenal states ; and that philosophy of life and order should decouple the concept of subjective experience from biological or functional complexity, challenging related anthropocentric assumptions; and finally, personal subjective experience retains its first-person significance precisely in the recognition that it cannot be captured as an object of description.
