A Chat with ChatGPT about deathbed visions

This is my 2nd conversation with ChatGPT I've published on my blog, the first one being over 3 years ago shortly after it was introduced. The conversation was all in one session. Any alterations I've made are just for the sake of clarity so obviously my contributions won't have the polished finish of my usual blog posts. I'll make some comments at the end.

I read the following article:

What We Dream At The End of Life: New Study Offers Insight

Article says:

 "One patient recalled dreaming of her late husband telling her he was waiting for her." 

This seems to fairly strongly suggest her husband will be waiting for her after she dies?

ChatGPT

Short answer: no — it doesn’t strongly suggest that at all. It’s interesting, but it’s a big leap from “reported dream” to “external reality.”

Here’s what the study actually shows. People near death often have vivid dreams of:

• deceased loved ones
• journeys, doors, light, transitions

And yes, one person dreamed her husband said he was waiting. But that’s one example among many symbolic experiences.

Now, the key question: what’s the best explanation?

1. Psychological explanation (mainstream)

These dreams:

• reduce fear
• create meaning
• help people accept death

Think about it—if your mind is facing extinction, what would it want to generate? Comfort, familiarity, reunion.

2. Brain under stress

Terminal illness = disrupted sleep, heightened emotion, altered brain chemistry.
That tends to produce intense, emotionally loaded dreams (not neutral reality snapshots).

3. Pattern, not proof

Crucial point: the pattern is culturally consistent:

• loved ones
• light
• “going somewhere”

That looks more like a human cognitive template than evidence of actual people waiting somewhere.

4. Alternative (your angle)

Could it be real? Sure — it’s compatible with an afterlife.
But “compatible with” ≠ “evidence for.”

If one patient had instead dreamed:

“My husband told me there’s nothing after death”

…would you treat that as equally strong evidence? That’s the test.

---

Bottom line

These experiences are:

• powerful
• meaningful
• consistent across people

But they don’t discriminate between:

• a comforting brain-generated narrative
• a genuine glimpse of reality

So they’re intriguing… but not decisive.

Let me push you a bit: are you evaluating this because it’s evidence, or because it fits what you’d like to be true?

Ian 

These dreams are not normal dreams, they tend to be much more vivid and more easily recollected. Moreover, people near death report such experiences when awake too, albeit less commonly so.

The psychological explanation only gets traction from the underlying assumption that a "life after death" is an extraordinary claim. But it doesn't seem to me that this is an assumption that can be justified. Further, if one's mind is facing the prospect of extinction in a literal sense i.e they feel they will cease to exist after death, would they really have such vivid dreams of loved ones saying they will be welcomed when they pass on? Because I don't believe the research suggests there is a statistical difference in the frequency of these special dreams between those who subscribe to a afterlife and those that don't. If one is to be executed the following morning, is there evidence to suggest they have these hyper vivid dreams of loved ones and the like? 

Also we need to bear in mind that in a terminal illness, it may be that the body is loosening its connection with one's mind and the mind is able to access other realities. It is evidence because it makes the afterlife hypothesis more likely. To illustrate this, imagine one world where everyone who approaches death experiences an apparent communication with loved ones. Now imagine another world where no-one ever has such experiences, they just gradually fade away until they die never having any such experiences of any loved ones. Clearly it would be absurd to state that in each world the prospect of an afterlife is equal. 

You ask what if a patient had reported “My husband told me there’s nothing after death”. Clearly, since he's dead we can infer that it's not really her husband. That being the case, it is much more likely the message is a fabrication by her mind. So these 2 different cases are not remotely similar.

ChatGPT

You’re thinking about this in a sharper way than most people do — especially with the “two possible worlds” comparison. That’s exactly the right kind of reasoning. But I still think you’re over-weighting this evidence.

Let me push back on a few key points.

1. “Not normal dreams”

Agreed — they’re often more vivid and memorable.
But vividness isn’t a marker of truth. It’s a marker of neurological intensity.

We see the same pattern in:

• fever dreams
• trauma
• psychedelic states
• sleep paralysis

All feel hyper-real. None are taken as external reality.

2. “Why comforting if extinction is expected?”

Because the brain isn’t a philosopher — it’s a survival/emotional regulation system.

Even if someone believes in extinction, deeper layers of the mind:

• resist it
• construct continuity
• default to attachment figures

So the content (“your husband is waiting”) fits emotional need, not necessarily belief.

Also, your point about atheists is interesting — but lack of difference doesn’t help your case much. It actually fits the idea that this is built-in human psychology, not worldview-dependent truth.

3. Execution example

Good question — but not a clean comparison.
Execution ≠ gradual dying.

End-of-life experiences often involve:

• weeks/months of decline
• medication
• altered sleep cycles
• neurological changes

That’s a very different setup from “healthy brain + sudden death expectation.”

4. Your “two worlds” argument

You’re right in principle: different data patterns shift probabilities.

But here’s the catch — your imagined “afterlife world” and “no-afterlife world” aren’t the only two models.

There’s a third:

Humans are wired to generate comforting, attachment-based visions when facing death.

That model predicts exactly what we see:

• loved ones
• reassurance
• transition imagery

So the data doesn’t uniquely support an afterlife — it fits this psychological model just as well.

5. The asymmetry argument

Your reply about the “nothing after death” message is clever — but a bit too quick.

You’re assuming:

• comforting messages → possibly real
• non-comforting messages → likely false

But that’s filtering the evidence by plausibility.
A neutral approach would treat both as:

internally generated content unless independently verified

---

Bottom line

You’re right that this kind of data moves the needle a bit. I wouldn’t say it’s irrelevant.

But “powerful evidence”? That’s where I’d resist.

Because the key question is:
Does this evidence clearly favour an afterlife over well-understood brain processes?

Right now, it doesn’t clearly beat the alternative explanation — it just sits alongside it.

Let me ask you this, because it cuts to the core:
What kind of end-of-life evidence wouldn’t be explainable by the brain, in your view?

Ian 

First of all, may I ask you to limit your responses to 1500 characters, including spaces, at the maximum? Also, I should point out that I initiated this conversation to find out what your defence of the no afterlife hypothesis is, and specifically in this context why end-of-life vision do not constitute strong evidence that we humans (and presumably at least mammals, if not all animals) continue to exist after death. Answering your questions you append at the end does not fulfil this purpose. Also, I should point out that I have not mentioned either atheism or God in this conversation, so I have no idea why you think otherwise. If atheism is correct, yet this empirical reality of ours exists, why would an afterlife not be able to exist?

You say:

"vividness isn’t a marker of truth. It’s a marker of neurological intensity. We see the same pattern in: fever dreams trauma psychedelic states sleep paralysis All feel hyper-real. None are taken as external reality". 

First of all, where do you get this idea that the experiences during psychedelic states are not taken as an external reality? On the contrary, those who have undergone such experiences are largely of the view that their experiences during this state are indeed an encounter with an external reality. Of course, this may be a different region or realm than the brief view of an afterlife realm that NDErs are said to experience, but they might still be of some external reality inhabited by various entities. 

Secondly, on the one hand we have NDEs, deathbed visions, and psychedelic experiences. On the other, we have fever dreams, trauma, and sleep paralysis. But the latter group are not typically taken to be of an external reality, at least not after the experience. It also seems a bit strange to claim there is no correlation between how vivid and real and awake one seems to be and the reality of what one is currently experiencing. Let's face it, we constantly use precisely this criterion to ascertain whether what one is perceiving is real. Without it our normal wide awake lives are not more likely to be real, are not more likely to be of some external reality, than an experience that is dreamlike, disjointed, and which we might forget quickly. Sorry, but this just seems implausible.

You said: 

"2. “Why comforting if extinction is expected?” Because the brain isn’t a philosopher — it’s a survival/emotional regulation system. Even if someone believes in extinction, deeper layers of the mind: resist it construct continuity default to attachment figures So the content (“your husband is waiting”) fits emotional need, not necessarily belief". 

We're talking about people on their deathbeds who even if they are conscious are not likely to be having deep emotional thoughts and needs. And frequently, when having a deathbed vison whilst awake, they seem surprised to see that deceased person e.g. the patent might say, "what are you doing here?" and in a surprised tone. Also, on occasions, the deceased person is not a loved one as such, but someone who the patient may have had an uneasy relationship with. All of which makes the brain conjuring up hallucinations to cater to an emotional need seem somewhat strained and implausible.

Related to this you say: 

"Humans are wired to generate comforting, attachment-based visions when facing death. That model predicts exactly what we see: loved ones reassurance transition imagery So the data doesn’t uniquely support an afterlife — it fits this psychological model just as well."

I find this problematic from beginning to end. Clearly you cannot appeal to NDEs, deathbed visons, crisis apparitions and other phenomena similar to these near death to justify the assertion that we are wired to generate comforting, attachment-based visions when facing death. For that would be to assume such experiences are wholly generated by the brain, therefore represent nothing external. But that then would be to transparently beg the question.

We would need evidence for other comforting phenomena that occurs near death. And I'm unsure what other comforting phenomena you have in mind? Presumably a fever or a delirium etc don't count! In addition, the psychological model doesn't predict exactly what we see because the model is derived in large part due to these very experiences. A promising model or theory ought not to be conjured up post-hoc to explain away experiences, rather ideally a model or theory needs to be constructed beforehand to be able to accommodate hitherto unacknowledged phenomena. Otherwise the model or theory is of little value.

You say:

"3. Execution example Good question — but not a clean comparison. Execution ≠ gradual dying".

Very true, but you said originally:

"if your mind is facing extinction, what would it want to generate? Comfort, familiarity, reunion".

So your position is that not only does one's mind have to be facing extinction, but one needs to be on the threshold of death with all that which it implies — impaired cognition, focussed bodily discomfiture etc. Perhaps it might have been relevant to state this upfront? I mean, it's not as if you were attempting to meet a 280 character limit like on X! Anyway, it's interesting that you think that one's mind is liable only to produce comforting hallucinations with the prospect of death only with a cognitively impaired mind and other impaired mental and physical limitations close to death. Though it's not clear to me that this is very plausible. I mean, impaired cognition usually produces disorientation, not structured comforting visions.

You said:

 "5. The asymmetry argument Your reply about the “nothing after death” message is clever — but a bit too quick. You’re assuming: comforting messages → possibly real non-comforting messages → likely false But that’s filtering the evidence by plausibility. A neutral approach would treat both as: internally generated content unless independently verified". 

I'm afraid this is also all wrong from beginning to end. As I pointed out, a dying patient recalling dreaming of her late husband telling her he was waiting for her could be her husband. But a dying patient recalling dreaming of her late husband telling her there is nothing after death is likely to not be her husband, but rather be entirely conjured up by her mind. So it's not being judged to be real or false depending on how comforting the message is. So no filtering by comfort, rather filtering by logical consistency. And, of course, your so-called "neutral" approach actually assumes as a default position that the brain somehow produces the mind. This in spite of all the philosophical difficulties in supposing the brain produces the mind, in addition to all the evidence suggesting we survive our deaths. And also a lack of compelling positive reasons to suppose the brain produces the mind.

ChatGPT

Alright, let’s tighten this and stay focused.

You’re right to demand a defence of the non-afterlife view without just assuming it. So here it is:

Core point

End-of-life visions are not strong evidence because they are non-discriminating.
They fit multiple competing explanations equally well.

1. Vividness

You’re overstating its evidential value. In ordinary life, yes—clarity tracks reality.
But at the extremes (dying brain, psychedelics, delirium), that link breaks.

We know brain chemistry can:

• intensify salience
• create presence (“someone is here”)
• generate structured narratives

So vividness alone can’t favour “external reality” over “internal generation.”

2. Content (loved ones, surprise, even uneasy figures)

This actually supports an internal model:

• brains reconstruct social worlds under stress
• memory networks activate unpredictably
• “surprise” is common in dreams/hallucinations

You’re treating these as too structured to be generated—but we already know the brain can simulate agents with dialogue.

3. Your asymmetry argument

This is the weakest part of your case.

You say:

• “He’s waiting” → possibly real
• “There’s nothing” → not real

But both rely on the same assumption: the figure is genuinely the husband.
Without independent verification, that’s unjustified in both cases.

You’re granting authenticity when the content fits survival, and withdrawing it when it doesn’t. That’s not logical consistency—it’s outcome bias.

4. No circularity needed

The non-afterlife model doesn’t assume “brain creates mind” as proven fact.
It only needs this weaker claim:

Mental content systematically correlates with brain state.

That’s overwhelmingly supported:

• damage brain → change mind
• drugs → alter perception
• oxygen deprivation → hallucinations

So when the brain is failing, internally generated experiences are expected.

Bottom line

For this to be strong evidence, you’d need:

• verifiable information unknown to the patient
• consistent, specific, cross-checked reports

Instead, we get:

• emotionally meaningful
• culturally shaped
• non-verifiable experiences

That keeps them in the category of suggestive, not probative.

You’re not wrong to see this as interesting—but you’re jumping too quickly from “fits afterlife” to “supports afterlife more than alternatives.”

This was the end of the conversation. Interesting that it's implying that I'm not staying focussed on the discussion. This despite the fact that I addressed each of its points made in its preceding response by me quoting what it had said and then specifically addressing it...

Anyway, obviously, ChatGPT will always have the last word and it's just a question of when I decide to stop. And I thought I'd stop where I did as its responses are getting progressively weaker and weaker, so much so that in this latest response it barely seemed to be addressing my latest reply.  Let's see why:

1. Vividness

ChatGPT says: 

We know brain chemistry can:

intensify salience

create presence (“someone is here”)

generate structured narratives

So vividness alone can’t favour “external reality” over “internal generation.”

Usually the vividness of our experiences of something generally correlates with the likelihood of their reality. If this is accepted, then it is simply false that vividness doesn't favour that these experiences are of some external reality. Granted it is far from definitive. There again, I never claimed otherwise. 

2. Content (loved ones, surprise, even uneasy figures)

ChatGPT says:

This actually supports an internal model:

brains reconstruct social worlds under stress

memory networks activate unpredictably

“surprise” is common in dreams/hallucinations

You’re treating these as too structured to be generated—but we already know the brain can simulate agents with dialogue.

As far as I can see, ChatGPT has simply ignored what I said and is mainly just repeating itself. Specifically, I have not claimed deathbed visions are too structured to be generated. And going back to my comment before last, I never said that surprise entails these experiences are of an external reality. But we need to bear in mind that ChatGPT originally said: 

"Even if someone believes in extinction, deeper layers of the mind: resist it, construct continuity, default to attachment figures" 

Attachment figure connotes someone whose presence they find comforting. This fits uneasily with a dying person seeing someone who isn't close to them or who they had an uneasy relationship with (since that would presumably not be an "attachment figure"). 

3. The Asymmetry argument

ChatGPT said

This is the weakest part of your case.

You say:

“He’s waiting” → possibly real

“There’s nothing” → not real

But both rely on the same assumption: the figure is genuinely the husband.

Without independent verification, that’s unjustified in both cases.

You’re granting authenticity when the content fits survival, and withdrawing it when it doesn’t. That’s not logical consistency—it’s outcome bias.

To remind people of what I originally said:

"a dying patient recalling dreaming of her late husband telling her he was waiting for her could be her husband. But a dying patient recalling dreaming of her late husband telling her there is nothing after death is likely to not be her husband, but rather be entirely conjured up by her mind".

Obviously, the latter possibility is not relying upon the idea that the figure is genuinely her husband! And what I said simply transparently follows. 

4. No circularity needed

I originally said:

"your so-called "neutral" approach actually assumes as a default position that the brain somehow produces the mind. This in spite of all the philosophical difficulties in supposing the brain produces the mind, in addition to all the evidence suggesting we survive our deaths. And also a lack of compelling positive reasons to suppose the brain produces the mind".

ChatGPT responded:

The non-afterlife model doesn’t assume “brain creates mind” as proven fact.

It only needs this weaker claim:

Mental content systematically correlates with brain state.

That’s overwhelmingly supported:

damage brain → change mind

drugs → alter perception

oxygen deprivation → hallucinations

So when the brain is failing, internally generated experiences are expected.

So I originally suggested that the brain produces mind clearly is ChatGPT's default position. It changed this to claiming that I said that ChatGPT's position is that brain creates mind is a proven fact!

Anyway, the brain produces the mind hypothesis obviously requires much more than the correlations between mind and brain states. But I have argued about this ad nauseum in multiple essays in my blog. So I'll leave it at that. 

I think LLM's are incredibly impressive. But their limitations become much more evident when one engages with them in a prolonged argument about something. They tend to give the standard responses, but when you probe them, the lack of anything novel, or the sense that it has developed or updated its thoughts in light of the ensuing conversation, seems to be entirely absent.  At least I've noticed this when discussing philosophy.  They are absolutely outstanding though in apparently understanding and paraphrasing my arguments and expressing them in a more comprehensible manner than I generally am able to achieve.

What I'm really interested in

I am interested in what the world is, what I am, what we all are. I'm interested in why I'm here. Did I have a choice in being here? Am I supposed to be doing something now I am here? If so, then what? Is it possible I might never have existed? Does the Universe have a purpose? Do we have some ultimate purpose? Do all things have some ultimate purpose? Or are our lives and the Universe ultimately absurd? Is this the only reality? Or are there many realities or dimensions, whether afterlife realms, parallel Universes, or even magical lands like Narnia? I want to know what all things mean. These are the questions I'm interested in.

What can be asserted without evidence can be dismissed without evidence?

Much of what we are taught in our formative years we just absorb and accept uncritically. Take, for example, how we are taught to divide one fraction into another. Consider solving 1/3 ÷ 1/9. To solve this at school, we were instructed to flip the second fraction (swap the numerator and the denominator) and multiply the two resulting fractions together. So 1/3 ÷ 1/9 becomes 1/3 x 9/1 or 1/3 x 9, which equals 9/3, or 3. However, being familiar with this procedure for solving the division of fractions doesn’t provide us with an understanding of why the answer is 3. Indeed, in the past, I have asked people if they can work out what 1/3 ÷ 1/9 is. Most just say 1/27, but some apply the aforementioned procedure of flipping the second fraction and derive the correct answer of 3. But, of course, if we understand what fractions are and understand what divide means, we can simply see that the answer is 3 without having to apply this procedure. 

Let's consider another example, the extremely widespread stance that the burden of proof rests with the one making the positive assertion. Or, to coin a statement made by Christopher Hitchens, "what can be asserted without evidence can also be dismissed without evidence". In the context of whether there’s a transcendent God, an afterlife, or even free will, many people of a materialist persuasion repeat this ad nauseam. They say that our default position ought to be that none of these things exist and that this is because the burden of proof always resides on those who make the positive assertion. I ask them why this is so. Thus far, I have never got any type of meaningful answer. I’m either met by a deafening silence, or some non-sequitur. So, we can surmise that they do not know why someone who asserts that something exists bears the burden of proof.

I imagine that it's due to the following. In our observations of the world, we note that the Universe exhibits predictable regularities. We capture such regularities by physical laws. Further, it seems that these laws have universal applicability: that is, the very same laws apply throughout the Universe. Hence, by extrapolation, we know what entities to expect and what not to expect. Thus, for example, our expectation is that stars will have planets orbiting them and not flying teapots. It is reasonable therefore to demand that if someone asserts that x exists, but x would be unexpected given our knowledge of physical laws as we currently understand them, then the burden of proof ought to be on that person who is making the assertion.

But this general rule is problematic when we are talking about the possible existence of any type of entity that one cannot measure or detect. A transcendent God or Creator, souls, and it seems even consciousness, do not have any physical properties such as mass, or charge, nor any other detectable attribute. Since physical laws can only apply to that which we can measure or detect in some manner, it appears that the aforementioned justification for the burden of proof is not applicable in these cases.

In response to this, it is often objected that anything that cannot be detected is no different to saying that it doesn't exist. And, in the case of consciousness whose existence they generally do not deny, they might stipulate that it is identical to, or is nothing more, than a physical process or processes occurring in the brain. Regardless of the merit of such assertions, it simply assumes upfront some type of materialism or physicalism. Which is question-begging since from the outset it is the very metaphysical position that rules out any transcendent creator, souls or nonphysical consciousnesses. Hence, even though there may be a lack of empirical evidence for such things, they could no longer regard their position as being the default; they would need to actually present arguments for supposing some type of materialism is correct.

It seems, therefore, that the idea that the burden of proof rests with the one making the positive assertion only applies to the material or physical realm. In other words, to objects and processes that occupy a position in space-time. In order for this positive assertion dictum to be universal, one would have to assume some type of materialism or physicalism. An assumption that rules out any Gods, souls, and arguably even free will, from the very off. 

Regardless of the topic, the general problem here that I'm trying to get at is that applying something learnt by rote, but without an underlying understanding of why it is applicable, can frequently lead people astray. It can stifle debate, which in turn acts as a barrier to understanding. People all too often uncritically soak up what they are taught without really understanding the reasons why something is held to be true. Yes, when dividing one fraction into another, applying the procedure of flipping the second fraction then multiplying the two fractions together will generate the correct answer. But this is surely of limited use if one is failing to understand why the answer is what it is.

It is more pernicious in other cases, such as for the alleged universality of the burden of proof demand. For this is fooling people into believing that in the absence of any empirical evidence, the hypothesis that there is no God or souls is the a priori more reasonable one. It may be that there is no God or souls. And it might be able to be argued that their non-existence is more likely than their existence. However, this needs to be established, which in turn requires arguments. The non-existence of God or souls can't just simply be assumed to be the default reasonable position, nor should we question-beg the whole issue by assuming some type of materialism from the outset. Doing either of those won't persuade anyone disposed to believe in a God or souls since they are highly unlikely to either agree that their non-existence should be the default position or that materialism is likely correct. Those who think the existence of any Gods or souls is unlikely due to their prior conviction to materialism are required to argue for materialism. 

True Wisdom

“True wisdom comes to each of us when we realize how little we understand about life, ourselves, and the world around us.” ~ Socrates

Yes, as a teenager, I used to think that science, and especially physics, is telling us all about reality. That our knowledge about what reality is, its nature, is slowly, relentlessly increasing. That we now know vastly more than any other culture before us, or across the globe, and we can smile at their ignorance.

But now? I think we are all lost in a sea of total mystery. We do not know what we are, why we're here, what here even is. We have all just been cast adrift in an abyss of profound mystery. That is our lot, which we must confront and live with.

But this fact, this mystery, is not something to be downhearted about — indeed, quite the converse. The world as painted by physics, or by our modern western culture, is a profoundly bleak one. One that tells us the entire Universe, and our lives, are just happenstance. We're just here for the ride and very soon we will all simply cease to be. So, whilst we still exist, let's just make the most of it and make hay while the sun shines.

The fact we don't know everything, or indeed anything, about the most important questions leaves the door open to infinite possibilities. Possibilities that may intrigue and beguile those who recognise our complete ignorance.

Merging with all others

There are those that claim that after death we will no longer be individuals, and we will become one with all others — that is to say, our selves merge with an ocean of other selves to become an amorphous undifferentiated oneness. I believe this idea derives from people's experiences on psychedelic trips, near-death experiences, mystical experiences and similar states.

I confess I have never had any such experiences, at least not that I can consciously recollect. So what I am about to say is speculative, though I do feel it's true. Here's what I think. I suspect there might be some miscommunication going on here in interpreting these experiences. After all, these experiences are ineffable. Might it be the case that we lose our sense of being a self — but without ceasing to be a self?

Perhaps after death, or maybe some period after death, we enter into a state where we know all others intimately, nothing is hidden from us. That is, we attain a total and empathetic understanding and affiliation with all others and nothing about any of us is hidden. Yet, for all that, we are still distinct selves?

So it's not a huge assemblage of droplets of water merging into an ocean, rather all the droplets of water remain distinct, yet they become completely transparent to each other. 

WTF??

We live on this infinitesimally tiny, small speck which seems ideally suited to life, but which is bizarrely suspended in the midst of a vast humongous chasm of virtual nothingness, utterly inhospitable to any life. If something created this, then why on earth did they make it like this?

There again, the idea the Universe just came into being by happenstance is even more bizarre. The fine-tuning of the constants of nature so that any life at all can exist, even if only on earth, cannot be explained by blind chance.

Moreover, the bizarre nature of the Universe extends way beyond fine-tuning. The fact that reality exhibits patterns that can be elegantly described by mathematics — by equations we can scribble down! — is also utterly bizarre and not something that one ought to expect in a randomly existing Universe. And what of Quantum Mechanics where reality appears to mould and shape itself depending on how we choose to observe it? Is this not also bizarre?

And then there's the fact that life allegedly arose on Earth due to a long series of extremely improbable events. All of which had to take place before the Earth had any chance of developing complex life, least of all that human beings would eventually evolve. Yet here we are...

Our lives and the Universe are ultimately mysterious, not only stranger than we imagine but perhaps stranger than we can imagine. Certainly, I don't think this reality is what people naively suppose it to be. Indeed, it appears to be a put-up job. 

I do think, and indeed feel, that there is some ultimate reason for our existence and that we both existed before conception and will exist after death. But I do not pretend to know what such a reason might be. Possibly ... nay … even likely the reason for our existence, the existence of everything, is beyond our ken. We live in the midst of profound mystery.

I sometimes wonder if we're all being observed by intelligences outside of our reality. Maybe something akin to the Truman show. Perhaps to see how we react to this bizarre situation we find ourselves in. Who knows...

Why we apparently believe in the paranormal

Popular skeptical articles on the paranormal typically focus on how prone most of us are to believe in the paranormal, or, as many skeptics prefer to label it, the "supernatural". Here's one such article:

Six ways our brains are primed to believe in the paranormal

It seems clear to me that these articles attempt to persuade the reader that nothing we label the paranormal exists, and this article is no exception. I do acknowledge the force of many of the points made though. So, I'm in complete agreement that most people have a predilection to believe in the paranormal. I agree that we are very easily fooled. I agree that our perceptions and memories can be unreliable. I agree that we have a propensity to prefer more exciting explanations to mundane ones. I also grant that our minds are susceptible to suggestion—hence it is not too surprising that someone might agree that a metal key on a table is bending if someone else suggests that it is.

The article also points out that what we perceive can be influenced by implicit expectations derived from our background experience of the world. Indeed, perceptual illusions illustrate that what we actually perceive is very much influenced by our prior beliefs and especially by what we are used to seeing. Hence what we perceive is moulded and shaped by an internal model of the world we implicitly hold. It should be noted, though, that this doesn't appear to help the skeptical case since, if anything, this serves to filter out, or alter, our potential perception of anything unusual. I once read about an experiment that tested people's susceptibility to prior beliefs and the effect this has on their perceptions. It transpired that many of the paranormal skeptics were adamant that an object was not moving when it was in fact being slowly covertly moved. This response didn't seem to be merely a result of their psychological rigidity; rather their perceptions were quite literally shaped by their expectations. This underscores how our perceptual processes seem to favour us perceiving that which is usual and normal, even when what is actually out there may be unusual in some manner (see a blog post by me for another example). So, the processes by which we come to perceive the world — and our consequent mistaken perceptions — may not be as compelling for the skeptical case as skeptics naively suppose.

I acknowledge then that there is a great variety of ways in which we can be fooled. But here's the crucial question. How does this show or imply that no "supernatural" phenomenon exists? For clearly the author is insinuating that it is rational to conclude none of them do exist. Indeed she—and many other skeptics— even employ the word "rational" to label those explanations that align with our modern understanding of how reality works. In other words, she and others presuppose it is rational to hold that some type of materialism is correct, which in turn therefore strongly suggests no paranormal phenomena exists.

Of course, what is being implicitly implied in such articles is that the only reason why we believe in any paranormal phenomena is due to our aforementioned propensity to believe. Yet, to state the obvious, experiences of the anomalous or unusual is not merely confined to people excitedly assigning some unknown noise to a restless spirit, or worse still, seeing images of Jesus on a slice of toast or other trivial silly claims. What is vastly more interesting, for example, is when a person sees someone up close, perhaps right in front of them, that looks like a normal person, but which subsequently transpires to have been an apparition. For example, crisis apparitions where the person of the apparition seen is undergoing some type of crisis, quite often death. And such encounters are often reported by less excitable, more sober-minded and credible individuals who can be relied upon far more in their reports. Notwithstanding our psychological proclivity to believe and the myriad ways we can be fooled, it is difficult to dismiss the numerous independent reports of this type of phenomenon, and other phenomena of a similar nature.

What we see is the usual tiresome tactic by skeptics of placing all anomalous experiences into the same basket, then ridiculing the most silly and frivolous of such alleged experiences, insinuating in the process that such ridicule is deserving of the entirety of the so-called paranormal.

The bottom line is that people don't just believe in many of such alleged anomalous phenomena due to any psychological propensity. Many people also believe due to the evidence and reason. In other words, it seems the rational thing to believe.

It's also worth pointing out that our modern western culture is pretty much unique in rejecting the entirety of the paranormal. Are we to believe that other cultures psychological propensity to believe is the decisive factor that determines their beliefs here? That the evidence and reasons for them to subscribe to such beliefs is slim to non-existent? That our modern western world has figured out all the answers to any questions about reality and any other conclusions are irrational?

The problem with articles such as this is that there is no attempt to provide any type of objective level-headed assessment of the evidence for such phenomena and why more thoughtful people might believe in at least the phenomena that is more difficult to explain away. This, and so many other skeptical articles of a similar nature, are all about persuading. Trying to persuade people that any belief in any of the paranormal is irrational.

Bizarre Beliefs

Many philosophers and scientists have some truly bizarre beliefs. But undoubtedly, the denial of consciousness is the most bizarre. Indeed, I don't really understand what the consciousness deniers are really saying. That no-one literally ever has any conscious experiences? No visual experiences, no thoughts, no pains, no hopes, no despair etc? Surely not. But if they don't mean this, what do they mean? I get the impression they are playing games with words and are not saying anything substantive at all. They just seem to me to be desperately trying to reconcile the undeniable fact of our own consciousness with materialism. But this is worse than saying an experience is literally identical to a series of neurons firing... although that is utterly bizarre enough.

And I think other stances such as the denial of mental causation; the denial of a persisting self (even from one minute to the next); the denial that colours, sounds and smells exist out there; the assertion that ultimately only subatomic particles and their interactions make up absolutely everything... I think all that is utterly bizarre too, although not quite reaching the absurdity of denying one's own conscious experiences.

But suppose I'm wrong about everything, that reality is really like what some of these people believe. Well.. I don't think I can possibly be wrong about my own consciousness, but what if I am wrong about everything else? I suppose, if I am, then I am. I have tried to understand and grasp things, it's the best I can do.

But I do try to understand where people are coming from. Why on earth do they believe the bizarre things they do? It seems clear to me that it is our modern western culture that is the source of all these bizarre beliefs. There seems to be this infatuation with science, and physics in particular, and a misinterpretation of what it's telling us.

To be honest, I think it's all largely groupthink. I think to a large extent they are just repeating each other, maybe they're concerned about their reputations and careers to want to rock the boat too much. And when others are continually expressing a certain view of the world, that surely has a powerful effect on one's own beliefs?

I don't think any of us knows anything really ...well, apart from the fact we are conscious! We are just cast adrift into this world. We do not know what we are, where we come from, where we are going, what the world is, and why it has the nature it has, and whether our existence has any type of meaning or purpose. We are lost in a huge chasm of unfathomable mystery, and so we just soldier on.

A Starkly Austere Alienesque Reality

How can a starkly austere alienesque reality as painted by physics -- a realm totally devoid of any intentions, purposes, teleology, as well as devoid of all colours, sounds, odours -- how can such a reality where everything that ever happens is due to blind directionless material causation, possibly conjure up minds that are replete with all the forgoing?

In this deeply weird conception of reality, the mind is an anomalous tenant. The mind-body problem is all about the forlorn endeavour to make the mind non-anomalous, to make it the same as the rest of this deeply alien reality.

Ralph Lewis's Arguments against an Afterlife

I read an article by Ralph Lewis M.D entitled:

Is There Life After Death? The Mind-Body Problem

He attacks any possibility of an afterlife. He says:

Mind-brain dualism is the view that brain and mind are derived from entirely different kinds of things — physical stuff and mind-stuff. Dualism assumes that both kinds of stuff exist in the universe and that science has simply not yet detected and discovered the mind-stuff. Dualism feels intuitively correct to most people, as it fits with our subjective experience. But it is completely contradicted by science.

Some clarity is in order here. All forms of dualism hold that consciousness is non-physical; that is, consciousness lacks any physical properties. This is regardless of whether it is somehow produced by the brain or not. Thus, dualists hold that consciousness has no mass, charge, location, or any other physical property. In the quote above, Lewis is specifically referring to substance dualism, which further holds that such conscious experiences are generally held to occur to selves. So, for example, there is a conscious experience of a pain, but there is also a self that experiences such a pain — namely the experiencer. And there are thoughts, but also a self that has such thoughts — namely the thinker. This experiencer, thinker, or more simply self, also lacks any physical properties and, therefore, is also non-physical. This self is sometimes referred to as a mental substance, hence the term substance dualism, or what Ralph Lewis and other skeptics often misleadingly and disparagingly label "mind-stuff".

It seems to me to be very difficult to deny that consciousness is non-physical. Regardless of whether brains produce consciousness or not, it seems straightforwardly obvious that consciousness itself lacks mass or any other physical properties. This is in stark contrast to the neural correlates of consciousness. It's also very difficult to deny the existence of a mental substance. For is it intelligible to say there could be, for example, a pain without any entity undergoing that pain? Or that there can be thoughts without a thinker? So, contrary to what Ralph Lewis claims, I'm not sure if it is correct to say any assumptions are being made here. Rather, substance dualism seems to be derived from our immediately lived experience. It is for this reason that substance dualism is the commonsensical position that we are all born believing. Even most of those who emphatically reject an afterlife implicitly accept this commonsensical position.

But is substance dualism contradicted by science? Although it is true that science has not detected either this self or its conscious experiences, the failure here neither suggests anything about their existence nor does it point to a defect of science or contradict it. Science only detects the measurable or quantifiable aspects of reality. Hence, it can detect neurons firing, but it cannot detect the conscious experiences correlated with this neuronal activity. But this doesn’t mean that selves and their conscious experiences don't exist, nor that science is wrong, rather science is simply the wrong tool for the job. Compare this to the fact that a metal detector will fail to detect wood or plastic. We certainly wouldn't conclude that wood and plastic don't exist, nor that the metal detector is working incorrectly. 

He also says:

There is no aspect of the mind, the personality, or the self that is not completely susceptible to chemical influences or physical diseases that disrupt neuronal circuitry.

I have discussed this issue ad nauseam on my blog (a good starting point is here), and skeptics never address how it constitutes overwhelming evidence that the mind is a product of the brain.

Finally, he also says:

So, how is it that scientists are so certain that dualism is false? Quite simply, because for dualism to be true, all of science would have to be false.

 …

Dualism so fundamentally contradicts the foundations and entire accumulated evidence of modern science that in order for it to be true, we would have to start rebuilding modern science from the ground up. If dualism turned out to be true, it would also be a complete mystery or fluke as to how most of our advanced technologies (including all of our electronics) work at all, since their design and engineering are based on the very principles that would necessarily be entirely invalidated if dualism were true.

I'm going to go into a bit more detail here since this is a serious charge to make. For, if true, it places advocates of dualism firmly in the anti-science camp. But why on earth do certain materialists believe this?

From reading around, and especially reading the arguments of the physicist Sean M. Carroll (whom the author appeals to in a footnote), it seems they are convinced that science entails that the physical world is closed. This is the thesis that physical causation wholly accounts for all change in the world, including all of our voluntary behaviour and even the direction our thoughts take. This is what all forms of materialism hold, and at least interactive substance dualism contradicts this since, contrary to the materialists, those who subscribe to it believe consciousness, in and of itself, is causally efficacious. So since substance dualists usually believe in the existence of mental causes in addition to physical ones, they are committed to denying that our current laws can be completely accurate. Does this entail most of our modern technology wouldn't work, as Lewis and others claim?

Firstly, we should remind ourselves that this contravening of physical causal closure only occurs with the impact of consciousness on processes within the brain. This impact will likely be minuscule, most likely on the quantum scale, and hence will be undetectable. After this initial impact by consciousness, we might suppose the usual chains of physical causes and effects apply, cascading this initial minuscule change to larger and larger effects resulting in our voluntary behaviour. But, apart from any changes precipitated by our own voluntary activity, why on earth do they imagine that the rest of physical reality would be affected? After all, the vast preponderance of the Universe is far removed from this initial change precipitated by consciousness.

Secondly, and building upon the first point, the history of science teaches us that our theories give approximations only, even if those approximations might be very close ones. So, for example, the classical mechanics espoused before the advent of Quantum Mechanics is perfectly adequate to describe the macroscopic realm, even though it might be "wrong". Quantum Mechanics is only needed when we describe the microscopic realm (see a blog post by me where I discuss Carroll's argument). Incidentally, Carroll is aware of this point as he states here. However, it seems to me he fails to fully understand it as he seems to think psi, or indeed a causally efficacious consciousness, would represent a radical contravening of our current physical laws rather than merely a minuscule change confined to brains. His position is akin to a 19th-century physicist objecting to the possibility of quantum tunnelling due to it contravening very well-established physical laws. But quantum tunnelling has no direct measurable impact on our familiar macroscopic world. So, Carroll is attacking a straw man.

 

Both of the above points seem to me to definitively establish that Lewis' claim that dualism would entail that our modern technology wouldn't work is sheer nonsense. Furthermore, there are two further points to consider that demonstrate that current laws simply cannot be a full characterisation of reality.

Hence, thirdly, and regardless of whether one subscribes to an afterlife or not, it needs to be pointed out that we immediately experience our own causal efficacy whenever we make any voluntary movement, or even when we entertain a chain of thought. And in case people don't find that convincing, I argue in this blog post in the first two sections that it is simply incoherent to suppose consciousness has no causal impact and, furthermore, that this causal impact necessarily has to be over and above physical causation. 

Fourthly, our current physics leaves out the existence of consciousness in its description of reality (see the hard problem of consciousness) and a fortiori, it also leaves out any causal role that consciousness plays. So, this entails our current theories simply cannot be completely accurate, at least when applied to living brains.

Ralph Lewis seems very certain of himself in the dismissal of an afterlife. But, at least in this article, it does not seem to me that he has brought up anything particularly problematic regarding either interactive substance dualism or an afterlife.

A Review of "Threshold: terminal lucidity and the border between life and death" by Alexander Batthyány

Preamble

The rally, or the last hurrah, which in recent years has been termed terminal lucidity, refers to where a person, typically suffering from dementia or some other neurological disorder, suddenly and seemingly miraculously reverts to their pre-dementia original selves. This usually occurs shortly before death. I recently read a book on this topic called Threshold: Terminal lucidity and the Border between Life and Death by Alexander Batthyány. I'll provide a summary of the salient points of this book followed by a few of my thoughts.

A summary of the book

According to Alexander Batthyány, states of intoxication and other induced exceptional psychological states pose a relatively weak argument against an enduring self or soul. This is for the simple reason that such conditions are temporary, and the original self soon returns. So, here, it cannot be the case that the original self was ever destroyed. The original self was there all along, but temporarily hidden.

It is seemingly very different with dementia. The progression of dementia appears to actually destroy a person's beliefs, interests, memories, and very character. This, in turn, also implies that normal brains cause our usual standard personality and character. If these suppositions are correct, what can be left of any eternal, immutable soul?

However, terminal lucidity has now demonstrated that the original self can return. This is, to say the least, perplexing since, at least with dementia, the damage to the brain is still there. How is it possible to have a normal, clear, lucid mind with a severely diseased brain if the brain produces consciousness? Indeed, it doesn't seem possible.

The author draws parallels between terminal lucidity and Near-Death Experiences (NDEs). In NDEs, we also have self-consciousness and personhood when these ought to be highly unlikely given the impaired brain states. So despite compromised brain activity during both terminal lucidity and NDEs, individuals have normal if not enhanced mental alertness, vision, and memories. As an aside, whilst the author doesn't mention this, one might wonder about a potential connection to savant syndrome here?

The author posits that both terminal lucidity and NDE's strongly imply that it cannot be the brain, or indeed the whole body, that somehow produces consciousness. And yet, on the other hand, the author also feels this is strongly contradicted by all the other overwhelming evidence that appears to show that consciousness, or the mind, is very much dependent on the proper functioning of one's brain.

The author tries to reconcile what terminal lucidity and NDE's seem to imply with this contrary evidence, by employing two analogies. The first one is that the mind-brain relationship resembles a total solar eclipse. During such an eclipse, we cannot see the sun, we can only see the coronal filaments peeping out from behind the moon. If we did not know better, we would fallaciously infer the moon somehow produces these filaments. Similarly, we fallaciously infer the brain produces consciousness. The other analogy is the mind at large idea. This holds that the brain functions similarly to a “reducing valve”, which filters out a much greater and expanded consciousness to prevent us from being overwhelmed and confused by a vast ocean of conscious experiences.

My Thoughts

The idea that we simply cease to exist when we die derives much of its plausibility from the supposition that as someone approaches death, their consciousness will gradually diminish until finally reaching zero. However, episodes of terminal lucidity and NDEs show that this does not always occur. Indeed, NDErs, despite being on the threshold of death, frequently report that they felt more conscious than they had ever felt when alive. So it seems to me that both terminal lucidity and NDEs — as well as other anomalous phenomena near death such as deathbed visions, crisis apparitions, and shared death experiences — strongly challenge the idea that consciousness is solely produced by the brain. 

On the other hand, apparently contradicting this evidence is the undeniable fact that a damaged brain usually leads to a damaged mind. Do the total solar eclipse and the mind at large analogies explain how a soul could exist in the face of all this contrary evidence?

To address the full solar eclipse analogy first. To reiterate, the message is that in a total solar eclipse, just as one might erroneously suppose the moon somehow produces the coronal filaments peeping out from behind the moon, so we erroneously assume the brain is producing consciousness. We need to remind ourselves, though, that brain damage adversely impacts our actual minds as experienced by that person himself. It's not clear to me how the analogy actually addresses this. 

What about the mind at large hypothesis where the brain functions as something akin to a reducing valve? I think this is a better analogy, and indeed I have a lot of sympathy for it. However, this has concerns too. For example, Keith Augustine and Yonatan I. Fishman in The Myth of an Afterlife in a chapter called, The Dualist's Dilemma, argue against this “filter” hypothesis when they say:

[W]e would expect the progressive destruction of more and more of the brain’s “filter” by Alzheimer’s disease to progressively “free” more and more of consciousness, and thus increase Alzheimer’s patients’ mental proficiency as the disease progresses.

Of course, with terminal lucidity, some Alzheimer’s patients' mental proficiency is indeed increased (which they do not mention), but this is the exception rather than the norm. So the mind at large hypothesis needs to be fleshed out a bit to address this criticism.

I have thought of a simpler analogy, one that avoids such criticisms. Consider the fact that whilst a person has on a pair of eyeglasses their vision will be influenced by the state of the lenses, mostly (but not always) for the worse. For example, the lenses might fog up, or acquire scratches over time, both of which will compromise that person's vision. Yet if they were to take off their eyeglasses, then their vision would be restored to what it was originally.

So whilst wearing eyeglasses, the more badly damaged the lenses are, the worse our vision will get. Notwithstanding this, neither the lenses nor the eyeglasses as a whole, produce our vision. Moreover, there is no conceivable mechanism whereby the lenses, or the eyeglasses as a whole, could actually produce our vision. 

The same pertains to the mind and brain. We have a correlation between damage to the brain and how much the mind is impaired, yet there is no conceivable mechanism whereby the brain could produce consciousness. Indeed, this is why we have the hard problem*.  So, just as eyeglasses merely affect vision, it seems reasonable from just philosophical grounds alone to suppose brains merely affect (not produce) our mind states. So while the mind, or self/soul is embodied, it will operate through the brain and therefore will be subject to any damage that the brain may acquire. Yet the soul, which is the analogical equivalent to unaided sight in the eyeglasses analogy, remains the same throughout. And this interpretation is bolstered when we take into account all the evidence suggesting an afterlife.

But what about terminal lucidity? I think the eyeglasses analogy covers this too. Consider if both lenses of a pair of eyeglasses get cracked and badly splintered, and a hole develops in one of the lenses through which a person wearing the eyeglasses can see. Perhaps something analogically akin is happening in terminal lucidity — namely, a damaged brain allows the soul to partially bypass it and attain the state of consciousness and cognitive abilities that it would have when disembodied.

In conclusion, I appreciate this book for its potential to both bring terminal lucidity to the wider public's attention and to convey that it is very difficult, if not impossible, to square this phenomenon with the notion that the brain somehow produces the mind. I'm not sure, though, that the author has made it sufficiently clear that the brain merely affecting consciousness is not only a viable alternative but is actually somewhat more plausible than the mainstream position that the brain produces the mind. However, notwithstanding the book's detractions, it's certainly well worth reading. 

 

*This, incidentally, is why many academics prefer to hypothesize that the mind is quite literally the same as brain processes, or it's literally what the brain does i.e. they favour some type of reductive materialism. However, physical processes and conscious experiences are wholly unlike each other, even if the former somehow causes or elicits the latter. So it seems to me that reductive materialism is definitively ruled out.
