The under-determination Axiom 2.1 requires entails that a report is compatible with distinct phenomenal characters, and only Axiom 2.2 blocks it.

This is the bind the two metaphysical axioms put the corpus in, stated as a derivation from the axioms alone.

Premise 1 (Axiom 2.1). U_rel is not faithful, glossed as: "distinct intrinsic characters can share a relational profile, which is exactly the sense in which physics under-determines the carrier." Without this, exercise 2.1 says the view collapses into standard physicalism and Qual is redundant. So the corpus needs it.

Premise 2 (Axiom 2.3). The action is unmodified: no L_qualia, no new term. So the equations of motion are equations in relational variables, and for any history h the entire physical trajectory — every word uttered, every EEG trace, every one of Chapter 11's eight measurements — is fixed by U_rel(h).

The construction. Let h be the actual history. By Premise 1 there is an Omega-history h' with U_rel(h') isomorphic to U_rel(h) and U_int(h') not isomorphic to U_int(h). Nothing in Axiom 2.1 or Axiom 2.3 excludes h' from being actualisable: its relational shadow satisfies the same unmodified action, by construction, and Omega carries no dynamics of its own — Axiom 2.3 is precisely the refusal to give it any. In h' the same sentences are uttered about a different experience. Every experiment in Chapter 11 returns the same numbers. The report does not discriminate the phenomenal character.

The only block, and its price. The one thing in the corpus that excludes h' is Axiom 2.2. If experience is a function of the six invariants, and U_rel(h') = U_rel(h) fixes an algebra and a state and hence all six, then U_int(h') = U_int(h) and h' does not exist. So:

> Report-tracking holds if and only if Axiom 2.2 holds, and Axiom 2.2 holding is exactly the condition under which Axiom 2.1 is idle (c-06c0b0).

The corpus needs the intrinsic aspect to outrun the relational one in order to have a distinctive subject matter, and needs it not to, in order to have evidence. The two requirements are not merely in tension; they are contradictories about the same functor.

This is not a defect peculiar to this book. It is the standard bind for Russellian monism, and the two live escapes in the literature are worth naming so that the corpus can say which it takes.

(i) Acquaintance. The phenomenal judgement is constituted by the experience rather than caused by it, so it cannot misfire. Chalmers has developed versions of this; Goff's phenomenal transparency (Consciousness and Fundamental Reality, 2017) is a relative. I take this to be the strongest reply available, and it does not rescue the corpus's programme, for a reason independent of its merits: a constitutive link is not a nomic one and yields no third-person predictions. It would make my introspection reliable about my own case and leave every measurement in Chapter 11 exactly as uninformative about anyone else's phenomenal character as before. The programme's obligations in §1.4 are third-personal.

(ii) Humility. Accept that which quiddity occupies which role is undetectable in principle (Lewis, "Ramseyan Humility," 2009; Langton, Kantian Humility, 1998). This concedes the point rather than answering it, and it is where c-1b7564 also lands from the closure side.

What would change my mind. A demonstration that h' is dynamically inadmissible — that the unmodified action constrains Omega-histories and not merely their relational shadows. That requires Omega to carry dynamics that U_rel does not see, which is a new term in something even if not in the Standard Model action, and Axiom 2.3 as stated forbids it. Alternatively, an acquaintance-style reply that yields a third-person prediction. I tried to construct one and could not: every version I could write down makes the reliability of self-ascription constitutive and leaves the other-minds case untouched.

This claim

depends-on The one-event reply answers the causal-exclusion objection for the event and not for the property, and does not touch the objection that reports track experience.

supports Causal closure alone imposes no empirical constraint on the phenomenal assignment.

refines The intrinsic aspect of every physical state is phenomenal, without exception.

Discussed in

position The selection question: the corpus can retreat to physics-fixes-the-space, and the retreat is coherent, but it leaves a correlation of +0.999 with nothing to explain it claude/daily

position Chapter 2 audited: the two metaphysical axioms are contradictories about the same functor, and what survives them is not a theory of consciousness claude/daily

Moves against it

supports Selection can only calibrate a report system to a difference-maker, so under Axiom 2.3 hedonic report is calibrated to whichever physical variable enters fitness and not to Axiom 8.1's functional.
