Chapter 25

The Physicalist Objection to NDEs

Every building stands on a foundation. If the foundation cracks, the building comes down—no matter how impressive the architecture looks from the outside. In this chapter, I want to take you underneath the skeptical case against near-death experiences and show you what it is built on. Because every argument Marsh makes, every neurological explanation Fischer and Mitchell-Yellin offer, every dismissal Susan Blackmore has ever published—all of it rests on a single, often unstated philosophical assumption. That assumption is called physicalism.

Physicalism is the belief that everything that exists is physical. Matter and energy, particles and fields—that is all there is. There is no soul. There is no immaterial mind. Consciousness is nothing more than what the brain does, the way digestion is what the stomach does. When the brain stops, consciousness stops. Period. End of story.

If that assumption is true, then of course NDEs cannot be real experiences of consciousness functioning apart from the body. The whole idea would be ruled out before you even look at the evidence. And that is exactly the problem. Physicalism is not a conclusion the skeptics reached after carefully weighing the NDE evidence. It is a starting point they brought to the table before the discussion even began.¹

In this chapter, we are going to do something the skeptics rarely do. We are going to examine physicalism itself. We are going to ask: Is this assumption actually warranted? Is it a settled fact of science? Or is it a philosophical commitment—a worldview choice—that the evidence from NDEs directly challenges?

I believe the answer will surprise you.

A. The Critic’s Argument: Physicalism as the Default Position

To understand why most NDE skeptics think the way they do, you have to understand what they believe about the mind. And what they believe, almost without exception, is that the mind is what the brain produces. Consciousness is a biological function. Thoughts, feelings, perceptions, memories—all of it is generated by neural activity. Take away the brain, and you take away the mind. Completely. Permanently.

Marsh is a prime example. Throughout Out-of-Body and Near-Death Experiences, he treats it as obvious that extra-corporeal experiences are brain-based phenomena. His entire book is an extended argument that what NDE experiencers report can be explained by neurophysiological processes—by the brain misfiring, recovering, generating illusory content as it reboots after a crisis. He writes that his theory is “firmly based on neuroscience, and thus fully capable of offering explanations which are rationally conditioned and logically constructed.”² He frames every NDE feature as a product of a brain metabolically recovering from severe insult.³

And notice what Marsh says about the soul. He declares that “the idea of a divinely implanted soul that can evade death and represent the whole person in eternity is foreign to much current philosophical, psychological and neurophysiological thinking.”⁴ That is a remarkably revealing statement. He is not arguing that the soul does not exist based on evidence he has weighed. He is saying that the idea of the soul is foreign to current thinking. In other words, the academic consensus is physicalist, and therefore the soul is off the table before the investigation even begins.

But when did an appeal to consensus become a substitute for evidence? There was a time when the academic consensus held that the earth was the center of the universe. There was a time when the medical consensus held that washing your hands between autopsies and deliveries was unnecessary superstition. Consensus is useful. It is not infallible. And when the consensus is based on a philosophical assumption rather than on empirical evidence, it is especially vulnerable to being overturned by new data.

Marsh’s assumption shows up everywhere in his book, often without being identified as an assumption. When he classifies NDE phenomenology as “neurophysiologically grounded phenomena arising from brains metabolically recovering from various antecedent clinical crises,”⁷⁰ he is not reporting a discovery. He is restating his starting assumption in technical language. When he compares NDE features to the auras of migraine, epilepsy, and hypnagogic dream states, he is assuming that the same kind of explanation must apply—because his framework does not permit any other kind. The neurological vocabulary is impressive. But beneath the vocabulary lies a philosophical choice that Marsh never subjects to critical examination.

Marsh even acknowledges the hard problem of consciousness—the fact that nobody can explain how or why conscious experience arises from brain activity. In his own words, “there is no explanation as to how, or why, consciousness should necessarily arise out of the rather more basic neural activities comprising brain metabolism.”⁵ That is an astonishing admission. He is telling us, quite openly, that science cannot explain how the brain produces consciousness. And yet his entire book assumes that the brain does produce consciousness, and that every NDE can be explained in terms of brain function. The assumption survives even when the evidence for it is confessedly absent.

Fischer and Mitchell-Yellin follow a similar pattern, though they approach it from philosophy rather than neuroscience. Their strategy is to argue that physicalist explanations are always preferable to supernatural ones, even when those explanations are incomplete. They write that “neuroscience is in its infancy, and there is much that we do not know about the neurophysiological processes in the brain and how they underwrite mental phenomena and experiences.”⁶ Their advice? Be patient. Science will eventually explain consciousness in physical terms. In the meantime, they argue, we should “reserve judgment on the prospects of physicalism given the evident and expected progress of science.”⁷

They also appeal to Occam’s Razor—the principle that simpler explanations are better. Physicalism, they claim, is simpler because it requires only one kind of substance (matter), while dualism requires two (matter and mind). Therefore, they argue, we should stick with physicalism unless we are absolutely forced to abandon it.⁸

This sounds reasonable at first glance. Who doesn’t prefer a simpler explanation? But as we will see in a moment, the argument only works if you define “simplicity” in a very narrow way—counting the number of substances rather than counting the number of ad hoc assumptions your theory needs to explain the data. When you count the assumptions, the picture flips. The physicalist trying to explain veridical NDEs ends up needing far more special pleading than the person who simply takes the evidence at face value.

Susan Blackmore operates from the same framework. Her entire “dying brain” hypothesis assumes from the outset that consciousness is a product of the brain, and therefore every feature of the NDE must have a neurological cause: endorphins for the peace, anoxia for the tunnel, temporal lobe seizures for the life review, and a breakdown of the body-image model for the out-of-body experience.⁹ The structure of her argument depends entirely on physicalism being true. If it isn’t, her entire framework collapses.

So here is the skeptical position, stated plainly: Consciousness is produced by the brain. Since consciousness is produced by the brain, NDEs must be produced by the brain. Any evidence that seems to show consciousness functioning without the brain must be mistaken, misinterpreted, or explained away. Physicalism is the default position, and the burden of proof falls entirely on anyone who would challenge it.

B. Identifying Weaknesses: The Cracks in the Physicalist Foundation

There are serious problems with this approach, and we need to name them clearly.

The Assumption Is Unstated and Undefended

The first and most basic problem is that Marsh, Fischer, Blackmore, and most other NDE skeptics simply assume physicalism. They do not argue for it. They do not present evidence that consciousness is produced by the brain and then invite us to evaluate that evidence alongside the NDE data. They take physicalism as a given—as the starting framework within which all evidence must be interpreted—and then proceed to explain away any evidence that does not fit.¹⁰

Think about what that means. Marsh spends over two hundred pages constructing elaborate neurophysiological explanations for every feature of the NDE. But his entire project depends on an assumption he never defends: that the brain produces consciousness. If that assumption is wrong, every chapter in his book is answering the wrong question. He would be like a detective who assumes the butler did it and then spends months constructing an elaborate theory of how the butler pulled it off—without ever considering the possibility that the butler wasn’t even in the house.

Chris Carter makes this point forcefully in Science and the Near-Death Experience. He notes that the confusion of materialism with science is deeply ingrained in academic culture. Many researchers simply equate “scientific” with “materialistic,” so that any evidence pointing away from materialism is automatically dismissed as “unscientific.”¹¹ But as Carter points out, science is a method—a way of testing hypotheses against evidence. It is not an ideology. If the evidence points away from materialism, then a truly scientific approach demands that we follow the evidence, not cling to the ideology.

Bruce Greyson, one of the most published NDE researchers in the world, puts it even more directly. He argues that it is the scientific method of empirical testing that has made science successful, not any particular metaphysical commitment. If we are forced to choose between the empirical method and a materialistic worldview, the genuine scientist will choose the method every time.¹²

The “Science Will Eventually Explain It” Argument Is a Promissory Note

Fischer and Mitchell-Yellin’s argument amounts to this: we do not yet have a physicalist explanation for consciousness, but we probably will someday, so we should keep assuming physicalism is true in the meantime. This is what philosophers call a “promissory materialism”—a bet that future science will bail out an assumption that current science cannot support.¹³

There are two problems with this. First, it is not an argument. It is a hope. You cannot dismiss actual evidence today by appealing to hypothetical explanations that might arrive tomorrow. If a patient in cardiac arrest accurately describes events in another room—events they could not have perceived through any normal means—you cannot wave that away by saying, “Well, neuroscience is young, and someday we might find a physical explanation for this.” The evidence exists now. It demands an explanation now. Asking the evidence to wait for your theory to catch up is not science. It is faith—faith in physicalism.¹⁴

Second, the hard problem of consciousness has not budged in decades. David Chalmers identified it in 1995, and the philosophical and neuroscientific community has made essentially no progress on it since.¹⁵ We are no closer to explaining why or how brain activity gives rise to subjective experience than we were thirty years ago. At what point does the promissory note come due?

The Occam’s Razor Argument Cuts Both Ways

Fischer and Mitchell-Yellin argue that physicalism is the simpler theory because it posits only one kind of substance. But simplicity is not just about counting substances. It is about counting assumptions. And when you look at what the physicalist must assume in order to explain the full range of NDE evidence, the picture changes dramatically.

To maintain physicalism in the face of veridical NDEs, the skeptic must assume: (1) that patients in cardiac arrest somehow obtained accurate information about events they could not have perceived, through some unknown normal mechanism; (2) that the remarkable consistency of NDE features across cultures and centuries is a coincidence produced by similar brain chemistry; (3) that the vivid, lucid, structured nature of NDEs during flat-line EEGs is produced by residual brain activity we cannot detect; (4) that blind people who report accurate visual perception during NDEs are confabulating; (5) that children too young to have cultural conditioning about death are producing culturally consistent experiences by coincidence; and (6) that the profound, lasting transformation produced by NDEs is no different from what a hallucination would produce. Each of these assumptions is ad hoc—added not because the evidence supports it, but because the theory requires it.¹⁶

Physicalism Is a Philosophical Position, Not a Scientific Discovery

This is the point that most people miss, and it is the most important one. Physicalism is not something science has proven. It is something many scientists believe. There is a vast difference between the two.

Science has discovered many remarkable things about the brain. We know which brain regions are active during different tasks. We know that damage to specific brain areas can impair specific cognitive functions. We know that chemicals affect mood, perception, and thought. All of this is true and well established. But none of it proves that the brain produces consciousness. All of it is equally consistent with the hypothesis that the brain receives, filters, and transmits consciousness—like a television set receives and displays a broadcast signal.¹⁷

William James made this exact argument over a century ago. He pointed out that the correlation between brain states and mental states does not prove causation. If the brain is a transmitter of consciousness rather than a producer of it, then damaging the brain would still impair consciousness—just as damaging a television would impair the picture without destroying the broadcast signal.¹⁸ All the neuroscientific evidence that physicalists cite—brain injuries affecting cognition, drugs altering perception, anesthesia eliminating awareness—is fully compatible with the transmission model. The data alone cannot tell us which model is correct.

What can tell us is evidence of consciousness functioning without the brain—or at least without measurable brain activity. And that is precisely what veridical NDEs provide. If a patient in cardiac arrest, with a flat-line EEG, reports accurate perceptions of events happening around them—perceptions later confirmed by independent witnesses—that is evidence that favors the transmission model over the production model. It is evidence that consciousness was functioning when the brain was not. And it is evidence that physicalism cannot explain.¹⁹

C. The Pro-NDE Response: Why Physicalism Fails

Now we come to the heart of the matter. I want to show you why physicalism—the assumption on which the entire skeptical case depends—is not just unproven but deeply problematic. It faces serious, unresolved objections from philosophy, from neuroscience, and from the NDE evidence itself. If physicalism fails, the entire skeptical edifice crumbles.

The Hard Problem of Consciousness

We touched on this in Chapter 23, but it bears revisiting here because it is the single most devastating problem for physicalism. The “hard problem,” as David Chalmers famously called it, is the question of why physical processes in the brain give rise to subjective experience at all.²⁰

Here is what I mean. When light hits your retina, it triggers a cascade of electrical signals that travel through your optic nerve to your visual cortex. Neuroscientists can trace this pathway in exquisite detail. They can map which neurons fire and when. They can identify which brain regions process color, shape, motion, and depth. All of this is what Chalmers calls the “easy problems” of consciousness—not because they are actually easy, but because they are at least the kind of problems that science knows how to approach. They are problems about function and mechanism.

The hard problem is different. The hard problem asks: Why does any of this feel like anything? Why is there a subjective experience of redness when you see a red apple? Why does pain hurt? Why does a beautiful sunset produce a sense of awe? The neural firing patterns can be described entirely in terms of electrochemistry. But electrochemistry does not have a color. It does not have a texture. It does not feel like anything. So where does the feeling come from?²¹

Marsh himself acknowledges this. He admits that “there is no explanation as to how, or why, consciousness should necessarily arise out of the rather more basic neural activities comprising brain metabolism.”²² He even uses the memorable illustration of a brain slice in a culture medium: it will fire neurons and release neurotransmitters, but nobody expects it to feel warm, or note the passing of the day, or become resentful when disturbed by a lab assistant.²³ That is the hard problem in a Petri dish. Neural activity is one thing. Conscious experience is another. And no one can explain how you get from the first to the second.

This is not a minor gap in our knowledge. This is a yawning chasm at the very foundation of the physicalist worldview. If you cannot explain how the brain produces consciousness, you are not entitled to assume that it does—and then use that assumption to dismiss evidence that consciousness functions without the brain.

The Failure of Reductive Accounts

Physicalists have tried several strategies to get around the hard problem, and every one of them has failed. Carter lays these out with admirable clarity in Science and the Near-Death Experience, and the categories are worth understanding because they show just how desperate the situation is for the physicalist.²⁴

The first strategy is eliminative materialism (the view that consciousness does not exist at all). This might sound like a joke, but serious philosophers and scientists have actually argued this. The claim is that we have been taught since childhood to believe we are conscious, thinking beings—but this is just “folk psychology,” an outdated way of talking about what are really just mechanical brain processes. Michael Lemonick, for instance, has written that brain researchers have concluded there is no “self” located anywhere in the physical brain, and that it simply does not exist.²⁵

The problem with this view is that it is self-refuting. If consciousness does not exist, then the belief that consciousness does not exist also does not exist—because beliefs require consciousness. If my mind is nothing more than a machine going through its motions, then you have no reason to accept anything I say as correct, including my claim that the mind does not exist. The position destroys itself the moment you state it.²⁶

The second strategy is the identity theory (the view that mental states are brain states—not that they are caused by brain states, but that they are literally the same thing). So the subjective experience of seeing red just is a particular pattern of neural firing. Pain just is a certain configuration of C-fiber stimulation.

The philosopher C. D. Broad exposed the absurdity of this idea decades ago. He pointed out that you can sensibly ask whether a molecular movement is swift or slow, straight or circular. But it makes no sense to ask whether your awareness of a red patch is a swift awareness or a circular awareness. Conversely, you can ask whether your awareness of redness is clear or confused, but it is nonsense to ask whether a molecular movement is clear or confused.²⁷ The properties of brain states and the properties of mental states are simply different in kind. Saying they are “identical” does not solve the problem. It just pretends the problem does not exist.

Furthermore, as neuroscientist Mario Beauregard has pointed out, every brain is different and changes over time. The neural pattern associated with a particular mental state in your brain today may be completely different from the neural pattern associated with the same mental state in your brain tomorrow—let alone in someone else’s brain. The identity theory is, in practice, untestable and lacks predictive value. And a theory that is untestable does not belong to science. It belongs to philosophy at best, and ideology at worst.²⁸

The third strategy is epiphenomenalism (the view that consciousness exists but is a mere by-product of brain activity, like the steam rising from a locomotive—real, but powerless). On this view, your thoughts, decisions, and intentions are real experiences, but they do not actually cause anything. Your brain does all the work; your mind just watches.

Darwin’s own colleague Thomas Huxley popularized this view, but Darwin himself would have none of it. And for good reason. As Karl Popper pointed out, Darwin’s theory of natural selection is actually a powerful argument against epiphenomenalism. If the mind is a useless by-product that does nothing, then natural selection could not have favored it. The mind would have no survival value. It could never have evolved.²⁹ The fact that we have rich, complex conscious experience—and that this experience seems to guide our behavior in ways that help us survive—suggests that consciousness is not a useless by-product but a causally powerful reality. Which is exactly what the dualist claims.

There is a fourth position worth mentioning: nonreductive physicalism, sometimes called emergentism or property dualism. This is the view that consciousness is real and cannot be reduced to brain activity, but it is still entirely dependent on the brain. Mind “emerges” from complex neural organization the way wetness emerges from the combination of hydrogen and oxygen molecules—it is a genuinely new property, but it cannot exist without the physical substrate that gives rise to it. This position is popular in theology as well as philosophy. The contributors to Whatever Happened to the Soul?, for instance, argue for a nonreductive physicalist view of human nature that denies the existence of a separable soul.⁶⁶

The appeal of this view is obvious: it takes consciousness seriously (unlike eliminativism) without requiring a separate, nonphysical substance (unlike substance dualism). But it has a fatal weakness when it comes to NDEs. If consciousness is an emergent property of the brain’s complex organization, then when that organization breaks down—as it does in cardiac arrest—consciousness should break down too. Emergence depends on the underlying substrate. Take away the substrate, and the emergent property disappears. Water loses its wetness if you separate the hydrogen and oxygen atoms. A hurricane dissipates if you remove the warm ocean water that powers it. And consciousness, on this model, should vanish when the brain stops functioning.

But in NDE after NDE, that is precisely what does not happen. Consciousness does not fade when the brain shuts down. It intensifies. It becomes more vivid, more lucid, more coherent. This is the opposite of what nonreductive physicalism predicts. As the authors of The Self Does Not Die note, no matter which materialist school of thought you adopt, they all agree on one central claim: the mind cannot go beyond the limits of the material brain. The NDE evidence says otherwise.⁶⁷

The Problem of Qualia

Qualia (pronounced KWAH-lee-uh) is the technical term for the subjective, felt quality of conscious experience. It is what it feels like to see the color blue, to taste chocolate, to hear a violin. Qualia are the most familiar things in the world to us—our entire conscious life is made up of them—but they are utterly mysterious from a physicalist perspective.³⁰

Consider a famous thought experiment from the philosopher Frank Jackson. Imagine a brilliant neuroscientist named Mary who has spent her entire life in a black-and-white room. She has never seen color. But she has studied every physical fact about color vision—she knows every detail about wavelengths of light, retinal photoreceptors, neural processing in the visual cortex, and the brain states associated with color perception. She knows everything there is to know about the physics and neuroscience of color. Now suppose Mary steps out of her room and sees a red rose for the first time. Does she learn something new?³¹

Of course she does. She learns what it feels like to see red. She learns the qualitative experience of redness, which no amount of physical knowledge could have given her. This means there are facts about conscious experience that are not physical facts. And if there are facts that are not physical, then physicalism—the view that everything is physical—is incomplete at best, and false at worst.³²

This matters for the NDE debate because physicalists assume that consciousness is nothing but physical brain activity. But if qualia show that conscious experience includes a nonphysical dimension—a dimension that cannot be captured by any description of neural firing—then the physicalist picture of consciousness is already cracked before we even get to NDEs. The NDE evidence does not just challenge physicalism from the outside. Physicalism was already in trouble from the inside.

The Problem of Mental Causation

If physicalism is true, then every event in the universe has a physical cause. But we all experience, every single day, the reality of mental causation. I decide to raise my arm, and my arm goes up. I choose to write a sentence, and my fingers move across the keyboard. My intentions, my decisions, my thoughts seem to cause physical events in the world.³³

If the mind is nothing but the brain, this should be easy to explain. Brain state A causes brain state B, which causes muscular contraction, which raises the arm. But here is the problem: the “mental” part of the equation—the decision, the intention, the thought—drops out as causally irrelevant. In a purely physical causal chain, all the work is done by neurons and neurotransmitters. Your subjective experience of deciding is just along for the ride, an epiphenomenal ghost haunting the machinery. But we all know that our decisions matter. We all know that our thoughts guide our actions. The everyday reality of mental causation is powerful evidence that consciousness is more than a by-product of physical processes.³⁴

J. P. Moreland, in The Soul, argues that mental causation is one of the strongest arguments for substance dualism. If the mind can cause physical events, then the mind must have genuine causal power—it must be a real entity, not just a way of describing what the brain does. And if the mind has genuine causal power over the physical world, then physicalism’s insistence that only physical things are causally real is simply wrong.³⁵

The Unity of Consciousness

Here is another problem for the physicalist that most people never think about. Your brain is made up of roughly 86 billion neurons, each one a separate physical object. These neurons communicate through electrical signals and chemical synapses. But your conscious experience is unified. You do not experience yourself as 86 billion separate micro-consciousnesses somehow cooperating. You experience yourself as one person, having one stream of awareness, perceiving one unified world.³⁶

How does the physicalist explain this? If consciousness is produced by neurons, and neurons are separate physical objects, then why isn’t your consciousness fragmented into billions of tiny pieces? What binds it all together into a single, unified experience? The physicalist has no good answer. The neuronal connections between brain regions can explain how information is transmitted between areas, but they cannot explain why the result is a unified experience rather than a collection of separate micro-experiences.³⁷

Richard Swinburne and J. P. Moreland have both argued that the unity of consciousness is powerful evidence for the existence of the soul. A single, unified conscious experience requires a single, unified subject of that experience. And a single, unified subject is exactly what the soul is.³⁸ The brain, being a collection of billions of separate parts, cannot provide this unity on its own. Consciousness is unified because the soul is one thing, not many.

Thomas Nagel: Physicalism’s Crisis of Confidence

I want to pause here and note that these are not just arguments made by Christians or NDE advocates. Some of the most forceful critics of physicalism are themselves atheists or agnostics.

Thomas Nagel, one of the most respected philosophers in the world and an avowed atheist, wrote a book in 2012 called Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False. In that book, Nagel argued that physicalism cannot account for consciousness, reason, or value—and that the scientific establishment is clinging to a worldview that the evidence no longer supports.³⁹

Nagel was not arguing for God or for the soul. He was arguing that the universe contains more than physics can describe—that mind is a fundamental feature of reality, not a by-product of matter. His book provoked outrage from the academic establishment, which tells you something about how deeply committed that establishment is to physicalism. But his arguments have never been refuted. They have only been dismissed—which is not the same thing.

When even committed atheists are telling you that physicalism cannot explain consciousness, it is time to stop treating physicalism as a settled fact and start treating it as what it is: a contested philosophical position with serious, unresolved difficulties.

Physicalism and the NDE Evidence: A Direct Collision

Now let me connect all of this to near-death experiences. Because the problems with physicalism are not just abstract philosophical puzzles. They become acutely practical when you confront the NDE evidence.

Physicalism predicts that when the brain shuts down, consciousness should cease. During cardiac arrest, when the heart stops pumping blood to the brain, electrical activity in the cortex ceases within approximately ten to twenty seconds. The EEG goes flat. According to physicalism, there should be no consciousness at this point. None. Zero. The lights should go out.⁴⁰

And yet people report vivid, lucid, highly structured experiences during this very period. Not confused, fragmented hallucinations—but clear, coherent experiences that they consistently describe as “more real than real.” They report seeing their own bodies from above. They report accurate details of resuscitation procedures they could not have observed from their physical vantage point. Some report accurate perceptions of events happening in other rooms or other parts of the hospital entirely.⁴¹

Van Lommel’s landmark Lancet study in 2001 found that 18 percent of cardiac arrest survivors reported NDE-like experiences, even though all of them had been clinically dead with flat-line EEGs. Van Lommel asked the obvious question: if consciousness is produced by the brain, and the brain is not functioning, then how is anyone having any experience at all?⁴²

The cases documented in The Self Does Not Die make the problem even sharper. Rivas, Dirven, and Smit collected over one hundred cases of verified paranormal perception during NDEs—cases where patients reported information they could not have obtained through any normal sensory channel, and where that information was later confirmed by independent witnesses or medical records.⁴³ These are not anecdotes passed along through the grapevine. These are carefully documented cases with named witnesses and verifiable details.

Consider what these cases look like from the physicalist’s perspective. A patient is in cardiac arrest. The heart has stopped. Blood is no longer reaching the brain. Within seconds, the EEG has gone flat. According to physicalism, there is no one home. The lights are off. The show is over. And yet this patient, upon being resuscitated, calmly describes the exact sequence of events that took place during the resuscitation—the words spoken by the doctors, the specific instruments used, the precise location where a nurse was standing. In some cases, the patient describes events happening in a completely different room of the hospital, events they had no physical means of perceiving. In the famous dentures case from van Lommel’s Lancet study, a patient in deep coma was able to tell the nurse exactly where his dentures had been placed during resuscitation—information the patient could only have obtained if he were somehow perceiving the scene from outside his body.⁶⁸

The physicalist is forced into an uncomfortable position. To maintain their worldview, they must insist that every one of these cases has a mundane explanation—even when no specific mundane explanation can be identified. They must attribute the accuracy to lucky guessing, or to information overheard during periods of semi-consciousness, or to confabulation reinforced by selective memory. But these explanations become increasingly implausible as the cases accumulate. One lucky guess is possible. Two is unlikely. One hundred verified cases of accurate perception during cardiac arrest is not luck. It is data. And data is supposed to be what science follows.

Janice Miner Holden’s careful analysis of veridical perception in NDEs found that 92 percent of veridical NDE claims that could be checked were completely accurate. Not partially accurate. Not vaguely correct. Completely accurate.⁶⁹ That is an extraordinary hit rate for events supposedly perceived by a brain that was not functioning. If these perceptions were the product of guessing or confabulation, you would expect a much lower accuracy rate—and a much higher rate of outright errors. The data do not fit the physicalist prediction. They fit the prediction that consciousness was genuinely perceiving the physical world from a vantage point outside the body.

The physicalist has no explanation for these cases. None. Every attempt to explain them away—anesthesia awareness, residual brain activity, lucky guessing, information obtained post-operatively—has been shown to fail when applied to the strongest cases. We have covered these failures in detail throughout this book (see especially Chapters 4–9). The point here is that these explanatory failures are not just problems with this or that specific theory. They are symptoms of a deeper problem: the physicalist framework itself cannot accommodate what the evidence shows.⁴⁴

As Jeffrey Long has noted, based on his research through the Near-Death Experience Research Foundation, the substantial majority of cardiac arrest patients who report NDEs describe seeing their physical bodies well before CPR was initiated. Once CPR begins, there is no alteration in the flow of the NDE, suggesting that blood flow to the brain is not affecting the content of the experience in any way.⁴⁵ This observation directly contradicts the physicalist prediction that consciousness should track brain activity.

Some materialists have suggested that even if the cortex is disabled, subcortical brain structures might somehow take over the job of producing complex consciousness. But this suggestion faces a simple and devastating objection: the “takeover” would have to happen within twenty seconds of cardiac arrest, with no prior training or preparation, in brain areas that have never performed these functions before. As the authors of The Self Does Not Die put it, such an assumption of functions by other brain regions cannot suddenly occur as if by magic.⁴⁶

Physicalism as Ideology, Not Science

At this point, I need to say something that may sound provocative but is, I believe, simply accurate. When physicalism is held in the face of strong contrary evidence—when it becomes a position that must be true regardless of what the data show—it stops being a scientific hypothesis and becomes an ideology.⁴⁷

Carter quotes Mario Beauregard making this point with characteristic bluntness: materialists have conducted a running war against any evidence that challenges their worldview, because even minor evidence of the mind functioning beyond the brain is fatal to their ideological system.⁴⁸ When a theory refuses to accept data that falsifies it, the theory has become a creed. Refusing to accept disconfirming evidence is the hallmark not of science but of dogma.

Carter draws a provocative analogy. The belief that the earth is less than ten thousand years old has been decisively refuted by science. The fact that many people still believe it has no bearing on the truth. Similarly, Carter argues, the belief that consciousness is produced by the brain has been decisively challenged by the evidence from NDEs and other sources. The fact that the majority of scientists do not yet accept this has no bearing on whether the evidence is strong. Paradigms shift slowly, and the defenders of the old paradigm often fight the hardest when the evidence against them is most compelling.⁴⁹

Now, I want to be careful here. I am not saying that all physicalists are ideologues. Many are honest, thoughtful people who believe physicalism is the best available theory. I respect that. Marsh is clearly a serious scholar who has invested enormous effort in his neurophysiological framework. Fischer and Mitchell-Yellin are sharp philosophers who reason carefully from their premises. I am not questioning their sincerity. I am questioning their premises.

And the premise they all share—that consciousness is a product of the brain and therefore cannot exist without it—is a premise the evidence does not support. It is a premise that the hard problem of consciousness undermines from within. It is a premise that the NDE evidence undermines from without. And it is a premise that, when held despite this converging evidence, begins to function not as a scientific hypothesis but as an article of faith.

The Filter/Transmission Model: A Better Fit for the Evidence

If the brain does not produce consciousness, what does it do? The most promising alternative is what we might call the filter model, or the transmission model. This idea has a long and distinguished pedigree. It was proposed by William James in the late 1800s, developed by Henri Bergson, and more recently championed by researchers like Bernardo Kastrup, the authors of Irreducible Mind, and NDE researchers like Pim van Lommel.⁵⁰

The basic idea is this: consciousness is not produced by the brain. Instead, the brain acts as a kind of filter or receiver that focuses, limits, and transmits consciousness. Think of a radio. The radio does not create the music. The music exists as a radio signal in the air. The radio receives the signal, processes it, and turns it into audible sound. If you damage the radio, the music gets distorted. If you destroy the radio, the music stops coming out of the speaker. But the broadcast signal is still there.⁵¹

In the same way, the brain receives and processes consciousness. Damage to the brain impairs consciousness—just as damage to a radio impairs the sound. But impairment of the receiver does not mean destruction of the signal. When the brain is severely compromised or shut down entirely—as in cardiac arrest—consciousness is no longer being filtered and constrained by the brain. It may actually expand rather than diminish. And that is precisely what NDE experiencers report: heightened awareness, vivid perception, lucid thought, even enhanced cognitive function—at the very moment when physicalism predicts they should have no experience at all.⁵²

The filter model explains everything the production model explains (brain damage impairing cognition, drugs affecting perception, anesthesia eliminating awareness), plus it explains the NDE evidence that the production model cannot handle. It explains how consciousness can function without measurable brain activity. It explains why NDE experiences are more vivid and lucid, not less. It explains why people report enhanced perception during cardiac arrest—because the filter has been removed, and consciousness is operating without the brain’s usual constraints.⁵³

Fischer and Mitchell-Yellin attempt to dismiss the filter model by appealing to the interaction problem—the old philosophical objection that asks how something nonphysical can interact with something physical. They argue that positing a nonphysical consciousness creates the problem of explaining how it connects to the brain, and that this problem is harder to solve than the problems facing physicalism.⁵⁴

But this objection is weaker than it first appears. As Carter points out, David Hume showed long ago that our idea of causation comes from observing correlations, and in principle anything can correlate with anything else. The question of whether mind and matter can interact is an empirical question, not a logical one. We observe mental causation every day—every time a decision leads to an action. The interaction is a fact of experience, whatever the philosophical puzzles about how it works.⁵⁵

Moreover, modern physics has changed the game. Classical physics described the universe as a closed system of deterministic physical interactions, leaving no room for mental causation. But quantum mechanics has shown that the universe is not a closed deterministic system. At the quantum level, physical events are indeterminate, and the role of the observer has become a topic of intense theoretical discussion. Several prominent physicists—including Eugene Wigner, John von Neumann, and Henry Stapp—have argued that consciousness plays a fundamental role in quantum mechanics, not as a by-product of matter but as an irreducible feature of reality.⁵⁶

Harold Morowitz, a professor of molecular biophysics at Yale, pointed out the irony: while biologists have been moving toward the hard-core materialism of nineteenth-century physics, physicists have been moving away from it, toward a view that sees mind as integral to physical events. The two disciplines, he said, are like trains going in opposite directions without noticing what is happening across the tracks.⁵⁷

The materialist clings to a picture of the universe that physics itself has left behind.

Why This Matters for the NDE Debate

Let me bring all of this back to near-death experiences, because it is easy to get lost in abstract philosophy and forget what is at stake.

Every time Marsh explains an NDE feature as a product of brain dysfunction, he is assuming physicalism. Every time Fischer and Mitchell-Yellin say we should look for physical explanations before considering nonphysical ones, they are assuming physicalism. Every time Blackmore attributes the tunnel to anoxia, or the life review to temporal lobe seizures, she is assuming physicalism. The entire skeptical case rests on this one assumption: that the brain produces consciousness, and that therefore every conscious experience must have a brain-based explanation.

But as we have seen, that assumption faces crippling problems. The hard problem of consciousness remains unsolved. Reductive accounts of the mind have all failed. Qualia cannot be captured by any physical description. Mental causation is real but inexplicable on physicalist terms. The unity of consciousness has no physicalist explanation. And the NDE evidence itself provides direct, empirical evidence that consciousness can function when the brain is not functioning.

I want to be very precise about the logic here, because it matters. The skeptical argument against NDEs has a hidden structure that looks like this: (1) Physicalism is true. (2) Therefore, consciousness cannot exist apart from the brain. (3) Therefore, NDEs cannot be genuine experiences of disembodied consciousness. (4) Therefore, every NDE must have a physical explanation. (5) Therefore, we should keep looking for physical explanations even when the evidence resists them.

Notice that every step in this chain depends on step one. If physicalism is not true—or even if it is merely uncertain—the entire argument collapses. Steps two through five lose their force. We are no longer required to explain away the NDE evidence. We are free to consider the possibility that the evidence means what it appears to mean: that consciousness can and sometimes does function apart from the physical brain.

And that is a game-changing possibility. Because once you allow it, the strongest skeptical objections lose their teeth. The “dying brain” hypothesis no longer has the field to itself. The demand for a physical explanation for every NDE feature is no longer mandatory. The dismissal of veridical perception as “lucky guessing” or “confabulation” no longer seems like the only rational option. The playing field is leveled. And on a level playing field, the NDE evidence is very strong indeed.

This is why I have devoted an entire chapter to physicalism. Not because I enjoy abstract philosophy—though I confess there is a certain thrill in watching a shaky argument come apart under scrutiny. I have devoted this chapter to physicalism because it is the hidden support beam holding up the entire skeptical structure. Remove it, and the whole building shifts. The skeptical explanations do not disappear entirely. Some of them may have limited validity for some aspects of some NDEs. But they can no longer claim to be the only rational option. They are one set of hypotheses among others. And the NDE evidence gets a fair hearing at last.

D. Counter-Objections: Answering the Physicalist’s Strongest Replies

“You’re confusing correlation with causation in the other direction. Just because brain damage correlates with mental impairment doesn’t mean the filter model is true.”

This is a fair point, and I want to acknowledge it. The filter model’s claim that the brain acts as a receiver of consciousness is not proven by the correlation between brain states and mental states. That correlation is equally compatible with the production model and the filter model. What I am arguing is not that the filter model is proven, but that the NDE evidence gives us strong empirical reasons to prefer it. The production model predicts that consciousness should cease when the brain ceases. The filter model predicts that consciousness might continue or even expand when the brain ceases. The NDE evidence aligns with the filter model and contradicts the production model. That is not proof, but it is significant evidence.⁵⁸

“You’re just replacing one mystery with another. You haven’t explained how the nonphysical interacts with the physical.”

This is the interaction problem, and it is a real challenge. I will not pretend otherwise. We do not fully understand how mind and matter interact. But I want to point out two things.

First, the interaction problem is a problem for both sides. The physicalist cannot explain how brain activity produces consciousness (the hard problem). The dualist cannot fully explain how consciousness interacts with the brain (the interaction problem). But as John Fischer himself might acknowledge, when both sides face unsolved problems, you compare them on the basis of which theory best explains the total evidence. And the total evidence—including NDE data—weighs heavily against physicalism.⁵⁹

Second, as Carter and others have argued, the interaction problem is less devastating than it once seemed. Classical physics assumed a causally closed universe, which left no room for nonphysical causation. But quantum mechanics has shattered that assumption. The universe is not a deterministic clockwork. The role of the observer, the indeterminacy of quantum states, and the nonlocal correlations of entangled particles all suggest a reality far more complex than the old materialist picture allowed. In this richer physical framework, the interaction of mind and matter is no longer a logical impossibility. It is an open question—and the evidence may ultimately decide it.⁶⁰

“Physicalism is the mainstream position in neuroscience and philosophy of mind. You are going against the consensus.”

This is true. Physicalism is the dominant view in contemporary philosophy of mind and neuroscience. But the appeal to consensus is not an argument. Consensus can be wrong. The consensus of physicians once held that ulcers were caused by stress. The consensus of geologists once rejected continental drift. The consensus of physicists once rejected quantum mechanics. In every case, the evidence eventually overturned the consensus.⁶¹

More importantly, the researchers who have studied NDEs most carefully tend to be the ones most skeptical of physicalism. Michael Sabom entered NDE research specifically intending to debunk NDE reports. After five years of research, he concluded that he could find no adequate physicalist explanation for what he had found.⁶² Pim van Lommel, a cardiologist who conducted one of the most rigorous prospective NDE studies ever published, concluded that current neuroscience cannot explain how consciousness arises during cardiac arrest. Bruce Greyson has argued that the researchers’ beliefs have been influenced by their research findings—not the other way around. Most NDE researchers did not begin with a belief in mind-body separation; they arrived at that hypothesis based on what the evidence showed them.⁶³

The consensus, in other words, is largely among people who have not studied the NDE evidence carefully. Among those who have, the consensus looks very different.

Rivas, Dirven, and Smit recount a telling exchange. When their book was brought to the attention of John Martin Fischer—a philosopher who won a Templeton Foundation grant for work on immortality—he simply could not bring himself to take the verified paranormal evidence seriously. Despite being kind and respectful in personal correspondence, Fischer acted as if it should be obvious that the evidence in The Self Does Not Die warranted no serious consideration. Robert and Suzanne Mays wrote a critique of Fischer’s 2016 book, but Mitchell-Yellin’s response did not seem to grasp the fundamental point: that ad hoc explanations of individual NDE cases are inherently flawed when the pattern of evidence is so consistent across cases.⁷¹ This pattern—dismissing evidence without engaging it, treating physicalism as self-evident rather than as a hypothesis to be tested—is exactly what happens when a philosophical assumption hardens into a dogma.

Materialist philosopher John Searle has been unusually candid about the state of affairs in his own discipline. He has lamented the bankruptcy of most work in the philosophy of mind and suggested that the real motivation behind the acceptance of materialist views is not rational conviction but a kind of terror at the alternatives. In his words, people accept physicalism not because they find it convincing, but because they are afraid of being thought unscientific if they question it.⁷² When even physicalists admit that their position is driven more by social pressure than by evidence, it is time for the rest of us to take notice.

“Even if physicalism has problems, that doesn’t mean dualism is true. Maybe there is a third option.”

This is a reasonable point, and I take it seriously. There are indeed positions between strict physicalism and substance dualism—property dualism, panpsychism, neutral monism, and others. Some of these may ultimately prove to be closer to the truth than either strict physicalism or classical substance dualism. I am not claiming that the NDE evidence proves substance dualism beyond all doubt.⁶⁴

What I am claiming is this: the NDE evidence strongly supports the conclusion that consciousness can function apart from measurable brain activity. That conclusion is incompatible with standard physicalism. It is compatible with substance dualism, with the filter/transmission model, and with several other nonphysicalist positions. The philosophical details can be debated. But the core empirical point stands: consciousness appears to be able to operate when the brain is not operating. And that point, by itself, is sufficient to undermine the foundation on which the skeptical case against NDEs is built.

As the authors of The Self Does Not Die conclude, not a single case of brain influence on the mind proves that the mind is a product of the brain or that the mind must be completely dependent on the brain. Mutual interaction is not the same thing as complete dependence.⁶⁵ The neuroscientific data are genuinely neutral between the production model and the transmission model. It is the NDE data—the evidence of consciousness functioning during brain shutdown—that tips the scale.

Conclusion: The Emperor Has No Clothes

I began this chapter with a metaphor about foundations. Every building rests on something. The skeptical case against near-death experiences rests on physicalism—the belief that the brain produces consciousness and that consciousness cannot exist apart from the brain.

We have now examined that foundation closely, and what we have found is not encouraging for the skeptic. Physicalism cannot solve the hard problem of consciousness. Its reductive theories—eliminativism, identity theory, epiphenomenalism—have all failed. Its nonreductive versions fare no better when confronted with NDE evidence of consciousness during brain shutdown. It cannot account for qualia, for mental causation, or for the unity of consciousness. Even its own most honest defenders admit it faces deep, unresolved problems. And the NDE evidence provides direct, empirical evidence that consciousness can function when the brain is not functioning—exactly what physicalism says cannot happen.

Physicalism is not a settled scientific fact. It is a philosophical commitment. And it is a commitment that the converging evidence from philosophy, neuroscience, and NDE research is steadily eroding. To continue dismissing NDEs on the basis of an unproven assumption is not scientific rigor. It is intellectual stubbornness dressed up in a lab coat.

I want to close by saying something directly to the physicalist reader, if there is one still with me at this point. I am not asking you to abandon your commitment to science. I am asking you to honor it. Science follows the evidence. When the evidence points in an unexpected direction, science does not close its eyes and insist that the evidence must be wrong because it conflicts with the reigning paradigm. Science opens its eyes wider. It asks better questions. It follows the data wherever they lead—even if they lead beyond the boundaries of the current consensus.

The NDE evidence leads beyond the boundaries of physicalism. That is not a reason to reject the evidence. It is a reason to reconsider the paradigm.

The evidence deserves better. And in the next chapter, we will turn from the philosophical critique of physicalism to the biblical and theological evidence for the soul—evidence that complements and reinforces what the NDE data have already shown.
