It argues that prehensions are the phenomenal counterparts of quantum states and events, that entangled systems coupled to the brain can provide the physical basis for a single macro-subject, and that quantum indeterminism leaves room for genuine agency. The central proposal in Section 5.2 is that personal identity over time is constituted by three requirements: (i) classical organizational connection of the brain, (ii) phenomenal continuity of prehensions, and (iii) identity of agents; the paper claims these can be given a physical counterpart by replacing (ii) and (iii) with (ii') identity of the sequence of states of the quantum entangled system. It further argues that the no-cloning theorem blocks fission and teleportation thought experiments, so the usual transitivity violations do not arise, and that the resulting account avoids both the simple view and purely factual reductionist criteria.","tokens_in":21947,"tokens_out":7222,"duration_ms":79491,"significance":"If its assumptions were established, the paper would offer an original account of personal identity grounded in quantum information rather than in material continuity, and the no-cloning argument is a concrete, non-trivial constraint that gives the proposal some philosophical teeth. The paper is also commendably explicit about one of its load-bearing commitments: it states in Section 5.2 that the existence of robust entangled quantum states in the brain is a necessary condition for the proposed notion of personal identity. However, the central claims are highly conditional. They rest on an unverified empirical assumption about brain-scale entanglement, on a stipulated rather than derived account of free choice, and on an ambiguity in the use of the no-cloning theorem. As a programmatic contribution the paper is valuable, but as a demonstration of a new theory of personal identity it is not yet convincing.","major_comments":[{"comment":"The paper states, 'The existence of such states is a necessary condition for the validity of this form of panpsychism as well as the proposed notion of personal identity,' but it provides no experimental evidence that robust, long-lived entangled quantum systems exist in the human brain under physiological conditions. The only concrete candidate mentioned, Fisher's Posner molecules (Fisher, 2015), is a theoretical proposal; no studies are cited showing that such states form, resist decoherence for behaviorally relevant durations, or couple to neural activity as required. Since the persistence criterion (ii') and the no-cloning argument are formulated entirely in terms of this quantum system, the central claim is conditional on an unestablished empirical assumption. The paper should either supply such evidence, or explicitly recast the proposal as a conditional theory with clearly stated testable consequences.","section":"§5.2"},{"comment":"The identification of quantum measurement outcomes with free choices is asserted rather than derived. The paper says that the self 'can choose' and that prehensions 'determine dispositions to action,' but in the quantum mechanics invoked here the probabilities of outcomes are fixed by the Born rule; adding an intrinsic phenomenal aspect to states does not, without further dynamical assumptions, give the agent a role in selecting among outcomes. The paper explicitly distinguishes freedom from randomness ('To be free is not to act randomly'), but it does not explain how non-random selection is implemented, instead referring to previous work. Because condition (iii), the identity of agents, and the notion of 'acts' in the persistence criteria depend on this freedom, the account needs a clearly stated additional assumption or mechanism before the proposed criteria can be evaluated.","section":"§4.2 and §5.1"},{"comment":"The no-cloning argument is ambiguous between token and type identity. The paper says 'two systems in the same state are indistinguishable' and 'identical people can be based on different material constituents,' which suggests that persistence is carried by informational content or state type. The no-cloning theorem, however, only forbids copying an arbitrary unknown token state; it does not rule out two independently prepared systems being in the same state. If the authors intend token-state identity, they should say so explicitly and reconcile it with the claim that identity is based on quantum information rather than matter; if they intend type identity, the no-cloning theorem is irrelevant to the fission and teleportation scenarios. As written, the argument does not establish that transitivity violations are impossible.","section":"§5.2"},{"comment":"The third condition, 'The agent A at time t is identical to A' at t'>t iff the acts of A at t were acts of A',' is circular or at least uninformative, since 'acts of A' already presupposes the identity it is meant to define. The paper later claims that the three conditions are 'sufficient to ensure personal identity' and that the second and third conditions are independent, but no argument is given for sufficiency, and the physical reduction (ii') is explicitly said not to capture the phenomenal aspect of agency. The status of IA as a primitive, a definition, or a testable condition needs to be clarified before the proposed criteria can be assessed.","section":"§5.2"}],"minor_comments":[{"comment":"The sentence 'the original quantum state is necessarily destroyed in any physical teleportation process without' appears incomplete; the final word 'without' dangles.","section":"§5.2"},{"comment":"There are several typographical errors in the references: 'Watanbe' should be 'Watanabe', 'Panspyshicsm' should be 'Panpsychism', and 'consciouusness' should be 'consciousness'.","section":"References"},{"comment":"The text 'from origio' should likely be 'from the origin', and the spelling 'prehesions' appears in place of 'prehensions' in a few places.","section":"§4.2"}],"recommendation":"major_revision","confidential_remarks":"The manuscript leans heavily on the authors' previous work, including forthcoming or recently published items, for the 'demonstration' that quantum panprotopsychism solves the combination problem; the editor may wish to verify that those sources are accepted.

The genuinely new piece is the use of the no-cloning theorem against Parfit-style fission and teleportation: if personal identity is partly constituted by a quantum state of an entangled brain system, then no perfect copy can be made, so the transitivity violations that plague psychological-continuity accounts do not arise. The second thing is that the whole proposal is explicitly conditional. Section 5.2 says: \"The existence of such states is a necessary condition for the validity of this form of panpsychism as well as the proposed notion of personal identity.\" The paper offers no experimental evidence that robust, long-lived entangled states exist in the brain; it cites Fisher's Posner molecules only as a candidate.\n\nWhat the paper does well: the three persistence criteria — classical organizational connection, phenomenal continuity of prehensions, identity of agents — are stated clearly, and the physical counterpart (identity of the sequence of states of the entangled quantum system) is a genuine step beyond the authors' earlier work. The no-cloning argument is a sharp, legitimate philosophical move: teleportation necessarily destroys the original state, and fission either preserves the entangled system in only one hemisphere or destroys it, so no transitivity violation follows. The paper also handles edge cases like fetuses and persistent vegetative states with care, and it is honest about what its physical anchor requires.\n\nThe soft spots are real but mostly concentrated in one place. The brain-scale entanglement premise is load-bearing: the personal-identity criteria and the no-cloning argument presuppose a unique, persisting quantum state. If decoherence destroys such states on cognitive timescales, the account has no physical anchor. Second, the paper identifies quantum measurement outcomes with free choices but does not explain how a random outcome becomes a meaning-governed choice; it frankly says \"we do not attempt to solve this issue here.\" Third, the \"agent\" who chooses is said not to be exhausted by physical states, which sits uneasily with the naturalistic framing and is the kind of extra entity a cautious reader will want clarified. Fourth, the repeated claim that previous papers \"demonstrated\" the quantum solution to the combination problem is stronger than what a philosophical argument can show; the present paper inherits that unverified foundation, though the personal-identity argument does use independent resources.\n\nThis is a serious speculative contribution, not a desk-reject. The no-cloning argument is publishable on its own if properly scoped, and the paper's explicit admission of its empirical precondition is a virtue. I would send it to peer review, with the request that the referee separate the conditional conceptual argument from the empirical conjecture about brain entanglement. I would not cite it in my own work unless I were working on panpsychism, but I would take it seriously.","headline":"A serious speculative extension of the authors' quantum panprotopsychist program, with a genuinely new no-cloning argument against fission and teleportation, but the personal-identity claim is explicitly hostage to unestablished brain-scale entanglement.","tokens_in":22390,"tokens_out":3464,"would_cite":false,"duration_ms":34022,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"A person persists as a sequence of entangled quantum states, not as matter or memory.","keywords":["panprotopsychism","personal identity","self-consciousness","quantum entanglement","prehension","no-cloning theorem","free will","nuclear-spin molecules"],"falsifier":"Look for stable entangled nuclear-spin states, such as Posner molecules in neurons, that survive across the timescales of synaptic firing and remain coupled to neural activity in living human brains.

The authors propose that a person persists when three conditions hold: the neural organization of the brain is causally connected over time, the prehensions of the subject continue, and the same agent performs the later acts. They claim these conditions have a physical counterpart in the identity of the sequence of states of the brain's entangled quantum system, so that identity is a quantum-information property rather than a matter of substance or pure psychology. This is meant to dissolve the standard paradoxes of fission and teleportation, because the no-cloning theorem forbids producing two numerically identical copies of the original person.

The identity-preserving work is done by continuity of that entanglement-backed state sequence together with the no-cloning theorem, which blocks the exact duplication that fission and teleportation scenarios require; the classical organizational connection supplies the causal bridge between earlier and later brain states.","core_discovery":"The central claim is that personal identity can be characterized by three requirements—classical organizational connection of the brain, phenomenal continuity of prehensions, and identity of agents—and that these are sufficient to ensure persistence once the quantum state sequence is included. In physical terms, the last two can be replaced by the identity of the sequence of states of the quantum entangled system coupled to the brain, where every change of state corresponds to a preparation or measurement event in the brain. The definition deliberately cannot be expressed in factual, third-person terms, because quantum states are not determinable by individual observations and any observation changes them. The authors argue that this is why the usual reductionist puzzle cases fail: fission and teleportation cannot produce a genuine second candidate for identity, since the no-cloning theorem guarantees that the original entangled state is destroyed or divided in any attempt to copy it.","pith_inferences":["If the account is right, 'mind uploading' by copying neural information would not transfer personal identity, but a procedure that physically moves the entangled quantum state itself without cloning might preserve it;
