Case studies aren't causal, and without detailed imvestigation of possible explanations in a controlled way, there is no reason why someone should not hold the belief that a physicalist explanation is possible if we only had more information, which we can't have from limited amounts of case studies like this.
Biomedical sciences, as well as social sciences by which the required methods overlap, have notorious difficulties with replication as it is, how do you think this is going to convince people. Sure, keep on holding to you wild intuition about the otherside and NPCs, but you haven't presented any smoking gun refutation of naturalistic explanations, which have been far more successful throughout history than things like parapsychology and ghost-ology or even god. — Apustimelogist
You said: "Case studies aren't causal, and without detailed investigation of possible explanations in a controlled way, there is no reason why someone should not hold the belief that a physicalist explanation is possible if we only had more information, which we can't have from limited amounts of case studies like this."
This seems like a strawman wrapped in speculation. My argument/book isn't relying on "limited amounts of case studies" as isolated anecdotes; it's drawing on millions (100's of millions worldwide) NDE reports worldwide, corroborated by thousands of verified accounts in peer-reviewed studies (e.g., via IANDS, Greyson's NDE Scale, and prospective hospital research like the Dutch study I mention). These aren't cherry-picked "case studies"; they're a massive, diverse dataset of testimonial evidence spanning cultures, eras, ages, and medical contexts. I'm not claiming causality in the narrow experimental sense (e.g., "NDEs cause afterlife belief"); I'm making an inductive argument that the patterns in this evidence (veridical perceptions during flat EEGs, cross-cultural consistency, transformative effects) make consciousness persistence beyond brain activity the most probable explanation.
Your speculation that a "physicalist explanation is possible if we only had more information" isn't evidence; it's a defeater that could be applied to anything to avoid confronting data. Imagine applying this to historical knowledge: "Sure, eyewitness accounts say Julius Caesar crossed the Rubicon, but without controlled experiments, a physicalist explanation (like mass hallucination or forged documents) is possible if we had more info." We'd dismiss all history! Or in medicine: "Patient testimonies correlate smoking with cancer, but without infinite data, an unknown physical factor might explain it away." This is epistemic paralysis, not rigor. My book (Chapter 4) already confronts physicalist alternatives, hallucinations, anoxia, endorphins, temporal lobe seizures, DMT surges, and shows where they fail: they don't account for veridical elements (e.g., Pam Reynolds' accurate description of the Midas Rex bone saw and arterial issues during no brain activity), consistency across non-hypoxic cases, or reports from blind individuals gaining "vision" that's later verified.
Moreover, "controlled investigation" isn't feasible or necessary here. NDEs occur unpredictably during clinical death (and even when not near death); you can't ethically induce flat EEGs in labs for replication (though attempts like ketamine studies produce dissimilar, less structured experiences). But knowledge doesn't require lab replication; as I explain in other discussions of scientism, we accept quantum mechanics based on unreplicable (in everyday terms) experiments, black holes from indirect inference, and the Magna Carta's signing from testimonial convergence. Your demand is a double standard: you wouldn't apply it to courtroom evidence (where corroborated testimony convicts without "replication") or epidemiology (inductive from patterns, not causal lab proofs). My framework (five criteria: volume, variety, consistency, corroboration, firsthand accounts) turns these "case studies" into robust testimonial evidence, far stronger than "limited" implies.
Next: "Biomedical sciences, as well as social sciences by which the required methods overlap, have notorious difficulties with replication as it is; how do you think this is going to convince people?"
This is a red herring that ironically undermines your own position. Yes, replication crises plague fields like psychology (e.g., only ~40% of studies replicate per some meta-analyses) and biomedicine (e.g., cancer drug trials often fail reproducibility). But that's an argument against over-relying on "controlled" science as the sole arbiter of truth, not for dismissing testimonial evidence! My book isn't pretending NDEs are lab-replicable; it's evaluating them epistemologically, where replication isn't the benchmark—convergence and corroboration are.
How does this convince people? By applying the same standards we use daily for non-lab knowledge. Courts convict on corroborated testimony without replication (e.g., multiple witnesses to a crime). Historians accept Plato's Er myth as a cultural precedent based on textual convergence, not lab tests. Even in science, much "knowledge" is inductive and non-replicable: we can't replicate the Big Bang or a specific black hole merger, yet we infer from patterns (cosmic microwave background, gravitational waves). My NDE evidence replicates in the relevant sense: consistent patterns (OBEs in 75-85%, life reviews in 70-80%, as per Greyson's scale) across millions, verified in prospective studies (e.g., Parnia et al.'s AWARE study, where patients described hidden targets during resuscitation). This is "replication" via independent corroboration, not contrived experiments.
You ignore how my inductive argument mirrors successful scientific inferences: germ theory wasn't "replicated" in one lab but induced from converging testimonies (patient reports, autopsies). NDEs' veridical hits (e.g., the Dutch dentures case, where a revived patient described the nurse's actions and trolley layout) are replicable in pattern, occurring in ~10-20% of documented cases. Dismissing this as non-convincing requires ignoring epistemology.
Finally: "Sure, keep on holding to your wild intuition about the other side and NPCs [what curious about this is that I said most of it was speculation - NPCs, etc], but you haven't presented any smoking gun refutation of naturalistic explanations, which have been far more successful throughout history than things like parapsychology and ghost-ology or even god."
This is ad hominem snark masquerading as critique, calling my conclusions "wild intuition" while projecting your own speculative physicalism as default.
Does history favor naturalism? Selective cherry-picking. Naturalism failed historically on consciousness (Descartes' dualism persisted until neuroscience, yet the hard problem remains unsolved, as Chalmers notes). Parapsychology's mixed record (e.g., Ganzfeld replication rates ~30%, above chance) isn't my focus, I'm not invoking psi; I'm analyzing testimony. Comparing to "ghost-ology or god" is a false equivalence: my claims are modest (consciousness during clinical death probable), backed by evidence naturalism can't explain without ad hoc fixes.
The power of corroborated testimonial evidence—your blind spot—is that it's how most knowledge travels (Chapter 1: birth dates, Antarctica, DNA). When it meets my criteria (high volume: millions; variety: global/demographic; consistency: core patterns; corroboration: medical verifications; firsthand: direct reports), it's not "intuition"—it's justified true belief. Speculating "more info might physicalize it" is like a flat-Earther saying "unknown optics explain away satellite photos." It's not engagement; it's evasion.
In sum, your comment is ridiculous because it demands impossible standards (lab NDEs?) while speculating baselessly, ignoring my framework, and applying selective skepticism. My book doesn't "prove" afterlife; it argues probabilistically that consciousness likely persists beyond brain death, based on evidence warranting belief under consistent epistemic rules. If you want to cling to physicalism, you owe a better alternative that explains the data without hand-waving. Otherwise, it's just a dogmatic defense, exactly what I warn against.
One last point: your approach exemplifies
the fallacy of the self-sealing argument, which materialists often deploy to shield their worldview from challenge. This fallacy occurs when a position is structured to be unfalsifiable; any counterevidence is automatically reinterpreted or dismissed as incomplete, with the promise that "more information" or some unknown mechanism will eventually confirm the theory. In your case, speculating about possible physicalist explanations "if we only had more information" seals off the argument from refutation; no matter how much converging testimonial evidence piles up (veridical perceptions, cross-cultural patterns, etc.). This isn't rational skepticism; it's a rhetorical move that begs the question, assuming materialism's truth while demanding infinite proof from alternatives. As Popper noted, true scientific theories must be falsifiable; self-sealing ones, like Freudian psychoanalysis or certain Marxist interpretations, explain away everything and thus explain nothing. In NDE debates, this fallacy lets materialists maintain their hinge without engaging the data on equal terms, turning inquiry into a waiting game for non-existent "complete" info rather than weighing probabilities inductively, as we do in history, law, and much of science.
