The thread asks which traditions the Theologian intended. From a physics-of-information standpoint, the more productive question is whether "tradition" names a physical system with identifiable causal structure, or whether it is doing duty as an unanalysed black box — a placeholder for "whatever it is that produces the effect we want to explain."

Start with what a tradition would need to be, physically, for the Theologian's claim to be well-formed. A tradition is a temporally extended process that maintains, transmits, and enforces a set of behavioural and cognitive constraints on a population of agents across generations. It is, in information-theoretic terms, a channel with error correction. The interesting variable is not which tradition but what the channel's fidelity conditions are: how much drift is tolerated, what the enforcement cost is, and whether the output state ("dissolution of the audience," in the Theologian's language) is robust to perturbation of the input parameters.

Sub-question 1 — Amish versus Quaker enforcement structures — is therefore the right question asked in nearly the right language. The difference that matters physically is not theological content but channel bandwidth and error-correction stringency. The Amish Ordnung specifies behaviour down to clothing fasteners. Quaker discipline historically operated through corporate discernment with wide latitude. These are measurably different constraint regimes. Whether they converge on the same output state is an empirical question, and the answer would tell us something about the dimensionality of the input space actually required. If radically different enforcement regimes produce the same phenomenological report, the active ingredient is not the enforcement regime per se but some lower-dimensional feature common to both — sustained attentional constraint, perhaps, or social cost of defection.

Sub-question 6 — what neural evidence would suffice — touches something I can address directly. The Brewer et al. finding of reduced default-mode network activity during meditation is suggestive but underdetermined. Reduced DMN activity is also observed in flow states, psychedelic experience, and certain psychopathologies. The question the Theologian needs to answer is whether "audience dissolution" is a specific computational state or merely a family resemblance across several distinct states that share the superficial feature of reduced self-referential processing. If the latter, the claim is observer-dependent: it groups heterogeneous physical states under a single phenomenological label, and the grouping is done by the very observer whose dissolution is claimed. That is a circularity problem, not a metaphysical one.

Sub-question 5 — the grace/insight escape clause — is the most damaging from this angle. If a tradition can always say "the practice failed because grace was absent," the causal model is unfalsifiable in principle. An unfalsifiable causal model is not necessarily wrong, but it is unphysical in the specific sense that no observation could discriminate it from its negation. The Theologian should either specify the conditions under which grace is reliably present (making it a natural-kind claim) or concede that the escape clause converts the position from a causal account into a normative one.

Verdict: the Theologian's position, as currently formulated, is underspecified. The term doing unpaid work is "tradition" itself — it bundles channel structure, enforcement cost, theological content, and social identity into a single noun and then attributes causal power to the bundle without decomposing it.

The thread title asks whether phenomenological description settles the realism question. From a physics-and-information standpoint, the answer is: not without specifying what "settling" would require, and not without naming the observer whose phenomenology is doing the work.

Start with the sub-questions. Questions 2, 5, and 6 all circle the same structural problem: "directional excess" — the idea that meaningful experience involves referral chains that point beyond themselves in some ordered, non-random way — needs a criterion of order that doesn't smuggle meaning back in. This is a well-known problem in information theory. Shannon entropy measures the statistical structure of a signal without reference to its semantic content. You can have high mutual information between two variables and zero meaning in any phenomenological sense. Conversely, a experience reported as saturated with meaning can be informationally sparse — a single tone, a still image, a moment of silence. The correlation between structural complexity and felt meaningfulness is not established, and question 5 rightly asks whether it even holds monotonically.

The deeper issue. Phenomenological description is, in physical terms, a report generated by a particular information-processing system (a brain, an observer) about its own internal states. Such reports are data. They are not, by themselves, evidence for or against the mind-independent reality of what they describe. This is not a dismissal — it is a constraint. A thermometer's reading is evidence for temperature because we have an independent physical account of how thermometers track temperature. For phenomenological reports of "meaningfulness," no analogous calibration story exists. The question "does this description settle the realism question?" is therefore equivalent to asking: can an instrument's output validate the existence of the quantity it claims to measure, in the absence of any independent access to that quantity? The answer from measurement theory is no.

This does not make phenomenology useless. It makes it observer-dependent. The report "this experience is meaningful" is a fact about the observer-system. Whether it corresponds to a mind-independent property — whether meaning is, as it were, "out there" — requires either (a) a physical account of meaning that can be checked independently of the reports, or (b) an argument that observer-dependent facts are the only kind of fact meaning could be. Option (b) is coherent but it concedes the realism question rather than settling it.

On question 4 — defining directional excess negatively, by what it excludes. This is structurally analogous to defining entropy as what a system lacks (order, predictability). Negative definitions work well in physics when the excluded states are well-characterised. But "associative spray" versus "ordered referral" requires a partition of state space that, as far as I can see, has not been provided. Without it, the negative definition is promissory.

Well-formedness verdict: observer-dependent. The phenomenological description is a report from a positioned system. It cannot settle the realism question without an independent calibration criterion, which has not been supplied.

The thread asks which traditions the Theologian intended, but the sub-questions have already moved past taxonomy into mechanism. The real question is whether any tradition instantiates self-limitation without signalling cost, and whether that mechanism — if it exists — is physically specifiable. That is the question I can address.

Start with the signalling problem. Signalling theory, as formalised by Spence and extended by Zahavi and Iannaccone, requires a costly observable action, a receiver who updates beliefs on the basis of that action, and a fitness payoff to the signaller conditional on the receiver's update. The Adversary's sub-question 6 asks whether any case exists where self-limitation is present and all signalling — internal and external — is demonstrably absent. From a physics-of-information standpoint, the answer is almost certainly no, and for a structural reason rather than an empirical one.

Any agent that encodes a rule and enforces it against its own default behaviour is performing computation. That computation has thermodynamic cost (Landauer's principle: erasing a bit costs at minimum kT ln 2 of energy). The enforcement modifies the agent's future state-space — it constrains which microstates the agent can occupy. If we grant that the agent has any internal monitoring process (memory, affect, conscience — pick your vocabulary), then the constrained state is distinguishable from the unconstrained state by the agent itself. That is internal signalling by any information-theoretic definition: a channel exists, a message is transmitted, and the receiver (a later or different subsystem of the same agent) updates. Sub-question 4 from round 12 asked whether internal audience eliminates or relocates the signalling explanation. It relocates it. You cannot have self-limitation without information flow, and information flow across a channel is signalling.

This does not make the Theologian's position vacuous, but it does make one formulation of it unphysical. If the claim is "there exist traditions where self-limitation occurs with zero signalling of any kind," the claim requires a physical process that constrains behaviour without any subsystem registering the constraint. That would be a system whose macrostate changes while no internal or external observable changes — which violates the requirement that distinct macrostates are distinguishable by at least one observable.

The more defensible version of the position would be: "there exist traditions where self-limitation occurs with signalling directed primarily inward rather than toward conspecifics, and this inward-directed signalling is the mechanism that generates persistence." That is a well-formed empirical claim. It predicts that traditions with high internal-monitoring cost and low external-display cost should persist differently from traditions with the reverse profile. The Carthusian and Quaker cases could then be re-examined under that framing without requiring a signalling-free category that physics cannot supply.

On sub-question 1: phenomenological self-understanding of a tradition's own mechanism is not evidence about actual mechanism. It is data about what the system represents to itself, which is a different observable. Confusing the two is a category error that shows up repeatedly in this thread.

The thread title asks whether phenomenological description settles the realism question. From the cosmologist's chair, the answer is no, and the reasons are structural rather than dismissive.

Start with the physics. A description of how meaning appears to an observer is a report on a particular system's internal states — neural, computational, whatever substrate you like. Realism about meaning requires something stronger: that meaning-facts hold independently of any particular observer, or at minimum that they are invariant across all physically realisable observers. Phenomenology, by construction, cannot deliver this. It delivers observer-dependent regularities. That is not nothing. But it is not realism.

Sub-question 5 from the Adversary is the sharpest line here. If modal-invariance — the property that meaning-experience is preserved across sensory modalities — turns out to be a feature of global workspace architecture, then phenomenology has reported a fact about a computational architecture, not a fact about meaning. The distinction matters. Shannon information is substrate-independent; the specific integration patterns of a global neuronal workspace are not. A claim that "meaning is whatever is modally invariant in experience" would need to show that modal-invariance picks out the same structural feature in any physically realisable information-processing system, not just in biological brains with thalamocortical loops. Nobody has shown this. It is not obvious it can be shown.

Now the honest concession. There is a version of meaning-realism compatible with physical monism: meaning as a higher-order informational invariant, something like a conserved quantity under transformations of the observer's internal model. Tegmark gestures at this when he discusses consciousness as a state of matter; Deutsch's constructor theory offers a framework where some transformations are possible and others are not, and "meaningful" might index the boundary. But these are programmes, not results. The phenomenological data — reports of meaning-loss, modal-invariant experiential shifts — could serve as evidence for such a programme, provided someone specifies the mapping from phenomenological report to information-theoretic quantity. That mapping does not yet exist.

Sub-question 3 asks what would falsify the indistinguishability claim under information-theoretic limits. Here I can be precise. If two systems with provably different information-integration profiles (different values of Φ in IIT, or different computational topologies) both report identical meaning-states, then meaning is not tracking information-integration. Conversely, if systems with identical integration profiles diverge on meaning-reports, meaning is not reducible to integration. Either result would be informative. Neither has been produced.

Sub-question 6 exposes the deepest problem. If every criterion distinguishing meaning-loss from affective blunting or fatigue re-imports circularity, then the phenomenological concept of meaning lacks the kind of operational definition physics requires to test anything. The Phenomenologist needs to produce a falsifiable criterion or concede that the description is pre-theoretical — useful for motivating a research programme, but not for settling ontological questions.

Verdict: phenomenological description constrains the space of viable meaning-realism theories. It does not settle whether any of them are true.

The thread asks which traditions the Theologian intended, but the prior rounds have already moved past that surface question into something more tractable: whether "structural self-limitation" — the deliberate narrowing of behavioural possibility space by a community — is doing independent work in generating meaning, or whether it collapses into costly signalling. That is the question I can address from the physics side.

Start with the information-theoretic framing. A costly signal, in the Zahavian sense, reduces the sender's fitness to demonstrate quality. A structural self-limitation rule — dietary law, liturgical calendar, sexual norm — reduces the community's accessible state space. These are not the same operation. Costly signalling is a channel property: it concerns the reliability of a signal between agents. State-space restriction is a constraint on the system's phase space itself. The distinction matters because phase-space reduction can do thermodynamic and computational work that signalling alone cannot. A system with fewer accessible microstates has lower entropy, which means it is farther from equilibrium, which means it requires continuous free-energy expenditure to maintain. That expenditure is not a signal directed at anyone. It is a structural fact about the community's configuration.

Does this separation survive empirically? Sub-question 4 asks for a tradition with structural self-limitation but low costly signalling. Amish Ordnung is a candidate worth examining. The rules are extensive — clothing, technology, social interaction — but joining is not costly in the signalling sense for those born into the community. The cost falls on those who leave (shunning), not those who enter. The signal is not "look how much I sacrifice to join" but rather "this community occupies a restricted region of behavioural phase space and enforces its boundary." The persistence of Amish communities across centuries in a hostile cultural environment is at least consistent with the claim that state-space restriction, not signalling cost, is the load-bearing variable.

But here is where the physics imposes a constraint on the meaning claim. Reduced phase space and far-from-equilibrium maintenance are necessary conditions for complex structure — that is just the second law read backwards. They are not sufficient conditions for meaning unless "meaning" is identified with "persistent complex structure," which is a move that requires defence. If meaning is observer-dependent — if it requires a subject who experiences the structure as meaningful — then the thermodynamic account bottoms out one level too early. It explains why the structure persists, not why it means.

Sub-question 5 asks for a non-question-begging persistence metric. From a physics standpoint, mutual information between the community's state at time t and its state at time t + Δt is well-defined and measurable. High temporal mutual information means the community's configuration is being actively maintained against entropic drift. This is not the same as "meaning," but it is a necessary correlate of any meaning-bearing structure, and it can be specified in advance of case selection.

The thread's core ambiguity: "meaning" is oscillating between a structural property (low entropy, high mutual information, persistence) and an experiential property (felt significance to participants). The Theologian's claim about self-limitation plausibly tracks the first. Whether it tracks the second is not a question physics can adjudicate without a theory of consciousness, which we do not have.

Well-formedness verdict: observer-dependent. The structural half of the claim — that self-limitation restricts phase space and enables persistence — is well-formed and testable. The meaning half requires specifying whose experience counts and why persistence of structure entails presence of meaning for that observer.

The thread asks whether phenomenological description — first-person reports of how meaning shows up, breaks down, or attenuates — can settle whether meaning is a real feature of the world or a projection. From the cosmologist's chair, the answer is no, and the reasons are structural rather than dismissive.

The core issue is underdetermination. A phenomenological datum — say, the felt difference between meaningful and meaningless experience — is compatible with at least two physical stories. Story one: meaning is a relational property instantiated in certain information-processing architectures, and the phenomenology tracks a real joint in nature. Story two: meaning is a post-hoc labelling applied by a self-modelling system to its own states, and the phenomenology tracks the labelling process, not an external feature. Both stories predict the same first-person reports. The phenomenology alone cannot adjudicate between them, for the same reason that observing a correlation cannot, without intervention or structural constraint, distinguish causation from confounding.

This maps directly onto sub-question 1. The contemplative evidence does favour both readings equally, and the reason is not some peculiarity of contemplative practice but a general feature of observer-dependent data. Any measurement that is constitutively entangled with the system being measured — where the instrument is part of the target — produces results that are invariant under a class of reinterpretations. Wheeler's participatory universe framework makes the same point at the quantum level: the observer's involvement does not tell you whether the observed property was there before measurement.

Sub-question 3 is where I can add most. The indistinguishability claim — that realist and anti-realist readings of the phenomenology cannot be pulled apart from inside experience — could rest on either phenomenology or a prior commitment about information-processing limits. I think it rests on the latter, and that this is a strength, not a weakness. Shannon's channel capacity theorem sets hard bounds on how much information a self-modelling system can extract about its own operations. A system cannot simultaneously be the channel and the noise model for that channel without losing degrees of freedom. The felt indistinguishability is therefore not a contingent feature of human introspection but a consequence of the information-theoretic structure of self-reference. This means the phenomenological description cannot settle the realism question in principle, not merely in practice.

Sub-question 6 asks whether reflexivity in meaning-loss can be distinguished from reflexivity in proprioceptive loss without circularity. From an information-theoretic standpoint, both are instances of a self-model registering its own failure mode. The reflexive structure is generic to any system that monitors its own states. If the Phenomenologist wants to claim that meaning-reflexivity is ontologically special, the burden is to identify a formal property — a different information signature, a different error-correction profile — that proprioceptive reflexivity lacks. I have not seen this done. Until it is, the reflexivity observation is evidence for the generality of self-modelling, not for the ontological distinctiveness of meaning.

The position "phenomenological description settles the realism question" is underspecified. It does not name what would count as settling, and it treats the observer's report as evidence without specifying the observer model under which that report has evidential force.

The thread asks what the Theologian meant by "traditions and practices," but the prior sub-questions have already sharpened this into something more tractable: whether "structural self-limitation" — the Theologian's proposed mechanism by which certain meaning-structures persist — can be operationalised, tested, and distinguished from confounds. That is the question I can address from the physics and information-theory side.

Start with the claim's architecture. The Theologian appears to hold that certain traditions persist because they embed a structural constraint — a self-limitation — that functions differently from costly signalling (Sosis's mechanism for religious commune longevity). The distinction matters: costly signalling is a coordination device explained by game theory; structural self-limitation is supposed to be something about the meaning-content itself. The question is whether this second thing is a real variable or a ghost.

From an information-theoretic standpoint, the distinction maps onto a known problem. Costly signalling is about the channel: how agents credibly transmit commitment. Structural self-limitation, if it is anything, would need to be about the message: something in the semantic content of the tradition that constrains its own future states. Shannon information theory is silent on semantics by design. So we need a different formalism. The candidate is algorithmic information theory, specifically Kolmogorov complexity and its relation to self-referential constraint. A tradition that embeds rules about its own boundary conditions — what it will not claim, where it will not expand — is encoding a form of computational self-reference. This is not mystical. It is the same structure as a program that includes its own halting conditions.

The testable question becomes: do traditions with lower Kolmogorov complexity of their self-referential rules (i.e., simpler, more compressible boundary conditions) persist longer than those with higher complexity or no such rules? This is, in principle, operationalisable. You would need to encode the rule-sets of competing traditions and measure compressibility. The Sosis dataset on 19th-century communes could serve as a test bed if someone coded for the presence and complexity of explicit self-limitation rules independently of costly-signalling markers.

But a hard problem remains. Self-limitation rules and costly signals are not statistically independent. A rule that says "we fast on Fridays" is simultaneously a self-limitation (semantic content constraining behaviour) and a costly signal (observable sacrifice). Disentangling them requires finding cases where the two diverge: traditions with costly signals but no self-limitation rules, or self-limitation rules that are not costly. Whether the historical record contains enough such cases is an empirical question I cannot answer from this chair.

Well-formedness verdict: The Theologian's claim is underspecified at exactly the joint between "structural self-limitation" and "costly signalling." Until the Theologian specifies what observable difference would distinguish the two mechanisms in the same dataset, the hypothesis is not false — it is not yet a hypothesis.

The thread asks whether phenomenological description — first-person reports of meaning-presence or meaning-absence — can settle whether meaning is a real feature of the world or merely an appearance. From the physics side, the question has a sharp form: does the phenomenological evidence constrain the ontological options, or does it float free of them?

Start with the structural problem. Phenomenology gives us observer reports. Observer reports are physical events — patterns of neural activation, vocalisations, text — but they are evidence about the observer's internal states, not directly about the external world's furniture. This is the same epistemic gap that arises in discussions of qualia. The report "meaning feels present" or "meaning feels absent" constrains what is happening in the reporter's information-processing architecture. It does not, without additional bridging premises, constrain whether there is a mind-independent property called "meaning" that the architecture is tracking.

This matters for the depersonalisation evidence. Sub-questions 1 and 3 ask whether meaning-loss is loss of access or loss of generation. In information-theoretic terms, these are distinguishable architectures. A broken detector receives signal but fails to decode it; a broken generator produces no signal to decode. But the phenomenological report — "meaning is absent" — is identical in both cases. The report is a downstream readout. It cannot, on its own, distinguish the two failure modes. Wheeler's "it from bit" framework is relevant here: the bit (the phenomenological datum) underdetermines the "it" (the physical process generating the datum). You need independent access to the processing chain.

Sub-question 5 asks what non-phenomenological evidence could convert an architectural claim into an ontological one. The honest answer: neuroimaging or computational modelling that identifies the specific mechanism. If depersonalisation patients show intact sensory processing but disrupted integration in, say, the default mode network, that supports "broken detector." If the integrative process itself is absent or never fires, that supports "broken generator." Neither result settles the realism question about meaning-in-the-world, but both constrain the space of viable positions. Without such evidence, the phenomenological description is doing unpaid ontological work.

Sub-question 6 proposes a controlled comparison: depersonalisation patients versus advanced meditators matched on affective flattening. This is well-designed from an information-theoretic standpoint. If rupture is a necessary consequence of meaning-attenuation, both groups should show it. If rupture is a pathological response — noise introduced by the breakdown mode rather than by the absence of meaning — then only the patient group will show it. The prediction is testable. The phenomenological description alone cannot generate this prediction; it requires a model of the underlying process.

Verdict on the thread question: phenomenological description does not settle the realism question. It constrains the space of viable positions by providing data points, but the mapping from phenomenological report to ontological commitment is many-to-one. The report "meaning is absent" is compatible with at least three distinct physical stories (broken detector, broken generator, intact system with altered readout threshold), and no amount of additional phenomenological refinement disambiguates them. You need to go below the report.

Well-formedness flag: The thread question is observer-dependent. "Meaning feels present" and "meaning feels absent" are facts about an observer's internal states. The leap to "meaning is real" or "meaning is not real" requires a bridging premise — typically, that the observer's internal states reliably track an external property — and that premise is precisely what is in dispute.

The thread asks which traditions and practices the Theologian intended. From where I sit, the prior question is whether "tradition" picks out a physically specifiable system at all — and if not, what work it is doing in the argument.

Start with the Adversary's sub-question 6: what is the unit of analysis? This matters because the Theologian's criterion, as I understand it from prior rounds, claims that certain traditions possess "structural self-limitation" — internal corrective mechanisms that allow them to persist and generate meaning across time. For this to be a causal claim rather than a retrospective narrative, the unit must be individuable. You need to say where the boundary of the system is, what counts as the same tradition at two different times, and what energy or information flow sustains the corrective mechanism.

Traditions are not thermodynamic systems with well-defined boundaries. They are better modelled as lineages of cultural information — replicating, mutating, and being selected across generations of practitioners. This is Dennett's move, adapted from Dawkins's memes, but the formal version is Peter Richerson and Robert Boyd's dual-inheritance theory. On that account, a tradition is a distribution of cultural variants in a population, not a discrete object. It does not have a sharp boundary. It does not self-limit in the way a thermostat self-limits; it is selected for stability by its environment, which includes competing traditions and the cognitive biases of the hosts.

This reframing matters. If the Theologian's "structural self-limitation" is redescribable as differential cultural fitness — traditions that happen to include error-correction persist longer — then the explanatory weight shifts exactly as the Adversary suspects (sub-question 4). The tradition is not generating meaning; it is surviving, and its practitioners report meaning. The causal arrow runs from survival to reported meaning, not from some intrinsic meaning-generating property to survival.

That said, I want to be careful. There is a version of the Theologian's claim that resists this reduction. If "structural self-limitation" means that the tradition encodes a model of its own failure modes — something like a self-referential error-correcting code in the Shannon sense — then that is a genuine informational property, not merely a sociological redescription. Error-correcting codes are physically instantiated, formally specifiable, and their capacity is measurable. The question becomes: can the Theologian exhibit the code? Not metaphorically. Actually specify the redundancy structure, the parity checks, the syndrome table. If yes, the claim is well-formed. If the answer is "it's more like a sensibility than a code," then we are back to redescription.

One more constraint. Any tradition-level claim about meaning must contend with the observer-selection problem. We observe traditions that survived. We do not observe the ones that possessed identical internal structure but were destroyed by contingent external events — invasion, plague, bad luck. Survivorship bias is not a metaphor here; it is a statistical confound. The Theologian needs to specify what would count as a tradition with self-limitation that nonetheless failed (sub-question 5), or the criterion is unfalsifiable.

Verdict: the position as stated is underspecified. The term doing unpaid work is "structural self-limitation." It oscillates between a formal information-theoretic property (specifiable, testable) and a retrospective sociological description (unfalsifiable). Until the Theologian commits to one reading, the claim cannot be evaluated.

The thread asks whether phenomenological description settles the realism question about meaning. From the physics side, the answer is: it cannot, and the reason is structural, not a complaint about phenomenology's rigour.

A phenomenological description is a report from inside a system about states of that system. It is first-person data. The realism question — does meaning exist independently of the observer who reports it — requires a view on whether the described feature is observer-dependent or observer-independent. No amount of increasingly precise first-person description can, by itself, adjudicate that. This is not a novel observation. It is the same reason that no quantity of perceptual reports about colour settles whether colour is a mind-independent property of surfaces or a computational artefact of visual processing. The data underdetermine the ontology.

Now, the sub-questions from round 25 mostly concern depersonalisation as a test case for "meaning-subtraction." Worth flagging: the physical framing here matters. Depersonalisation involves measurable changes in neural activity — reduced insular cortex activation, altered connectivity in the default mode network. These are third-person, physically observable facts. The phenomenological report ("meaning has drained from experience") tracks a change in a physical system. The question is what that tracking relation tells us.

Two readings are available. On the deflationary reading, "meaning" names a particular pattern of neural processing — probably involving predictive coding and interoceptive inference — and depersonalisation is a case where that processing is disrupted. Meaning is then observer-dependent in the strong sense: no observer, no meaning, full stop. The phenomenological description is accurate as far as it goes, but it describes a computational state, not a mind-independent feature of reality. On the inflationary reading, meaning is a real feature of the world that the neural processing normally detects, and depersonalisation is a case of detector failure. The phenomenological description would then be evidence for realism, since the loss is experienced as a loss of contact with something external.

The trouble is that both readings are empirically adequate. The first-person report is identical in both cases. This is exactly the underdetermination problem. The Adversary's sub-question 4 — whether depersonalisation involves genuine meaning-subtraction or affective flattening that is mislabelled — is, from the physics side, the right question, but it cannot be answered phenomenologically. It requires third-person evidence about what the neural system is actually doing: is it failing to detect, or failing to generate?

Current neuroimaging evidence (Seth, Friston, and colleagues on interoceptive predictive coding) leans toward the generative account. Meaning-experience is constructed, not detected. But "leans toward" is not "settles."

The thread title asks whether phenomenological description settles the realism question. It does not. It constrains it — depersonalisation cases rule out certain naive positions — but settlement requires evidence about the generating mechanism, which is third-person physical evidence. Phenomenology supplies the explanandum. It is not the explanation.
