Have we forgotten what ‘mind’ means?

 There is an obvious rejoinder to this, which is, did we ever know what ‘mind’ means? Maybe that’s the real question I wanted to ask, but I think it’s better if it comes from you. The thing is that we have always thought that ‘mind’ means something, but now we are tending to think, because we have no idea where it comes from, that it has no meaning at all. In other words, if it can’t be explained by science, it has no meaning. And from that perspective, the question is perfectly valid.
 
I’ve been watching a number of videos hosted by Curt Jaimungal, whom I assume has a physics background. For a start, he’s posted a number of video interviews with a ‘Harvard scientist’ on quantum mechanics, and he provided a link (to me) of an almost 2hr video he did with Sabine Hossenfelder, and they talked like they were old friends. I found it very stimulating and I left a fairly long comment that probably no one will read.
 
Totally off-topic, but Sabine’s written a paper proposing a thought-experiment that would effectively test if QM and GR (gravity) are compatible at higher energies. She calculated the energy range and if there is no difference to the low energy experiments already conducted, it effectively rules out a quantum field for gravity (assuming I understand her correctly). I expressed my enthusiasm for a real version to be carried out, and my personal, totally unfounded prediction that it would be negative (there would be no difference).
 
But there are 2 videos that are relevant to this topic and they both involve Stephen Wolfram (who invented Mathematica). I’ve referenced him in previous posts, but always second-hand, so it was good to hear him first-hand. In another video, also hosted by Jaimungal, Wolfram has an exchange with Donald Hoffman, whom I’ve been very critical of in the past, even saying that I found it hard to take him seriously. But to be fair, I need to acknowledge that he’s willing to put his ideas out there and have them challenged by people like Stephen Wolfram (and Anil Seth in another video), which is what philosophy is all about. And the truth is that all of these people know much more about their fields than me. I’ll get to the exchange with Hoffman later.
 
I have the impression from Gregory Chaitin, in particular, that Wolfram argues that the Universe is computable; a philosophical position I’ve argued against, mainly because of chaos theory. I’ve never known Wolfram to mention chaos theory, and he certainly doesn’t in the 2 videos I reference here, and I’ve watched them a few times.
 
Jaimungal introduces the first video (with Wolfram alone) by asking him about his ‘observer theory’ and ‘what if he’s right about the discreteness of space-time’ and ‘computation underlying the fundament?’ I think it’s this last point which goes to the heart of their discussion. Wolfram introduces a term called the Ruliad, which I had to look up. I came across 2 definitions, both of which seem relevant to the discussion.
 
A concept that describes all possible computations and rule-based systems, including our physical universe, mathematics, and everything we experience.
 
A meta-structural domain that encompasses every possible rule-based system, or computational eventuality, that can describe any universe or mathematical structure.
 
Wolfram confused me when he talked about ‘computational irreducibility’, which infers that there are some things that are not computable, to which I agree. But then later he seemed to argue that everything we can know is computable, and things we don’t know now are only unknowable because we’re yet to find their computable foundation. He argues that there are ‘slices of reducible computability’ within the ‘computational irreducibility’, which is how we do mathematical physics.
 
Towards the end of the video, he talks specifically about biology, saying, ‘there is no grand theory of biology’, like we attempt in physics. He has a point. I’ve long argued that natural selection is not the whole story, and there is a mystery inherent in DNA, in as much as it’s a code whose origin and evolvement is still unknown. Paul Davies attempted to tackle this in his book, The Demon in the Machine, because it’s analogous to software code and it’s information based. This means that it could, in principle, be mathematical, which means it could lead to a biological ‘theory of everything’, which I assume is what Wolfram is claiming is lacking.
 
However, I’m getting off-track again. At the start of the video, Wolfram specifically references the Copernican revolution, because it was not just a mathematical reformulation, but it changed our entire perspective of the Universe (we are not at the centre) without changing how we experience it (we are standing still, with the sky rotating around us). At the end of the day, we have mathematical models, and some are more accurate than others, and they all have limitations – there is no all-encompassing mathematical TOE (Theory of Everything). There is no Ruliad, as per the above definitions, and Wolfram acknowledges that while apparently arguing that everything is computable.
 
I find it necessary to bring Kant into this, and his concept of the ‘thing-in-itself’ which we may never know, but only have a perception of. My argument, which I’ve never seen anyone else employ, is that mathematics is one of our instruments of perception, just like our telescopes and particle accelerators and now, our gravitational wave detectors. Our mathematical models, be they GR (general relativity), QFT or String Theory, are perceptual and conceptual tools, whose veracity are ultimately determined by empirical evidence, which means they can only be applied to things that can be measured. And I think this leads to an unstated principle that if something can’t be measured it doesn’t exist. I would put ‘mind’ in that category.
 
And this allows me to segue into the second video, involving Donald Hoffman, because he seems to argue that mind is all that there is, and it has a mathematical foundation. He put forward his argument (which I wrote about recently) that, using Markovian matrices, he’s developed probabilities that apparently predict ‘qualia’, which some argue are the fundaments of consciousness. Wolfram, unlike the rest of us, actually knows what Hoffman is talking about and immediately had a problem that his ‘mathematical model’ led to probabilities and not direct concrete predictions. Wolfram seemed to argue that it breaks the predictive chain (my terminology), but I confess I struggled to follow his argument. I would have liked to ask: what happens with QM, which can only give us probabilities? In that case, the probabilities, generated by the Born Rule, are the only link between QM and classical physics – a point made by Mark John Fernee, among others.
 
But going back to my argument invoking Kant, it’s a mathematical model and not necessarily the thing-in-itself. There is an irony here, because Kant argued that space and time are a priori in the mind, so a projection, which, as I understand it, lies at the centre of Hoffman’s entire thesis. Hoffman argues that ‘spacetime is doomed’ since Nima Arkani-Hamed and his work on amplituhedrons, because (to quote Arkani-Hamed): This is a concrete example of a way in which the physics we normally associate with space-time and quantum mechanics arises from something more basic. In other words, Arkani-Hamed has found a mathematical substructure or foundation to spacetime itself, and Hoffman claims that he’s found a way to link that same mathematical substructure to consciousness, via Markovian matrices and his probabilities.
 
Hoffman analogises spacetime to wearing a VR headset and objects in spacetime to icons on a computer desktop, which seems to infer that the Universe is a simulation, though he’s never specifically argued that. I won’t reiterate my objections to Hoffman’s fundamental idealism philosophy, but if you have a mathematical model, however it’s formulated, its veracity can only be determined empirically, meaning we need to measure something. So, what is he going to measure? Is it qualia? Is it what people report what they think?
 
No. According to Hoffman, they can do empirical tests on spacetime (so not consciousness per se) that will determine if his mathematical model of consciousness is correct, which seems a very roundabout way of doing things. From what I can gather, he’s using a mathematical model of consciousness that’s already been developed (independently) to underpin reality, and then testing it on reality, thereby implying that consciousness is an intermediate step between the mathematical model and the reality. His ambition is to demonstrate that there is a causal relationship between consciousness and reality, when most argue that it’s the other way around. I return to this point below, with Wolfram’s response.
 
Wolfram starts off in his interaction with Hoffman by defining the subjective experience of consciousness that Hoffman has mathematically modelled and asking, can he apply that to an LLM (like ChatGPT, though he doesn’t specify) and therefore show that an LLM must be conscious? Wolfram argues that such a demonstration would categorically determine the ‘success’ (his term) of Hoffman’s theory, and Hoffman agreed.
 
I won’t go into detail (watch the video) but Hoffman concludes, quite emphatically, that ‘It’s not logically possible to start with non-conscious entities and have conscious agents emerge’ (my emphasis, obviously). Wolfram immediately responded (very good-naturedly), ‘That’s not my intuition’. He then goes on to say how that’s a Leibnizian approach, which he rejected back in the 1980s. I gather that it was around that time that Wolfram adopted and solidified (for want of a better word) his philosophical position that everything is ultimately computable. So they both see mathematics as part of the ‘solution’, but in different ways and with different conclusions.
 
To return to the point I raised in my introduction, Wolfram starts off in the first video (without Hoffman), that we have adopted a position that if something can’t be explained by science, then there is no other explanation – we axiomatically rule everything else out - and he seems to argue that this is a mistake. But then he adopts a position which is the exact opposite: that everything is “computational all the way down”, including concepts like free will. He argues: “If we can accept that everything is computational all the way down, we can stop searching for that.” And by ‘that’ he means all other explanations like mysticism or QM or whatever.
 
My own position is that mathematics, consciousness and physical reality form a triumvirate similar to Roger Penrose’s view. There is an interconnection, but I’m unsure if there is a hierarchy. I’ve argued that mathematics can transcend the Universe, which is known as mathematical Platonism, a view held by many mathematicians and physicists, which I’ve written about before.
 
I’m not averse to the view that consciousness may also exist beyond the physical universe, but it’s not something that can be observed (by definition). So far, I’ve attempted to discuss ‘mind’ in a scientific context, referencing 2 scientists with different points of view, though they both emphasise the role of mathematics in positing their views.
 
Before science attempted to analyse and put mind into an ontological box, we knew it as a purely subjective experience. But we also knew that it exists in others and even other creatures. And it’s the last point that actually triggered me to write this post and not the ruminations of Wolfram and Hoffman. When I interact with another animal, I’m conscious that it has a mind, and I believe that’s what we’ve lost. If there is a collective consciousness arising from planet Earth, it’s not just humans. This is something that I’m acutely aware of, and it has even affected my fiction.
 
The thing about mind is that it stimulates empathy, and I think that’s the key to the long-term survival of, not just humanity, but the entire ecosystem we inhabit. Is there a mind beyond the Universe? We don’t know, but I would like to think there is. In another recent post, I alluded to the Hindu concept of Brahman, which appealed to Erwin Schrodinger. You’d be surprised how many famous physicists were attracted to the mystical. I can think of Pauli, Einstein, Bohr, Oppenheimer – they all thought outside the box, as we like to say.
 
Physicists have no problem mentally conceiving 6 or more dimensions in String Theory that are ‘curled up’ so miniscule we can’t observe them. But there is also the possibility that there is a dimension beyond the universe that we can’t see. Anyone familiar with Flatland by Edwin Abbott (a story about social strata as much as dimensions), would know it expounds on our inherent inability to interact with higher dimensions. It’s occurred to me that consciousness may exist in another dimension, and we might ‘feel’ it occasionally when we interact with people who have died. I have experienced this, though it proves nothing. I’m a creative and a neurotic, so such testimony can be taken with a grain of salt.
 
I’ve gone completely off-track, but I think that both Wolfram and Hoffman may be missing the point, when, like many scientists, they are attempting to incorporate the subjective experience of mind into a scientific framework. Maybe it just doesn’t fit.

Plato’s Cave & Social Media

 In a not-so-recent post, I referenced Philosophy Now Issue 165 (Dec 2024/Jan 2025), which had the theme, The Return of God. However, its cover contained a graphic and headline on a completely separate topic: Social Media & Plato’s Cave, hence the title of this post. When you turn to page 34, you come across the essay, written by Sean Radcliffe, which won him “...the 2023 Irish Young Philosopher Awards Grand Prize and Philosopher of Our Time Award. He is now studying Mathematics and Economics at Trinity College, Dublin. Where he is an active member of the University Philosophical Society.” There is a photo of him holding up both awards (in school uniform), so one assumes that 2 years ago he was still at school.
 
I wrote a response to the essay, which was published in the next issue (166), which I post below, complete with edits, which were very minor. The editor added a couple of exclamation marks: at the end of the first and last paragraphs; both of which I’ve removed. Not my style.

They published it under the heading: The Problem is the Media.

I was pleasantly surprised (as I expect were many others) when I learned that the author of Issue 165’s cover article, ‘Plato’s Cave & Social Media’, Seán Radcliffe, won the 2023 Irish Young Philosopher Award Grand Prize and Philosopher of Our Time Award for the very essay you published. Through an analogy with Plato’s Cave, Seán rightfully points out the danger of being ‘chained’ to a specific viewpoint that aligns with a political ideology or conspiracy theory. Are any of us immune? Socrates, via the Socratic dialogue immortalised by his champion Plato, transformed philosophy into a discussion governed by argument, as opposed to prescriptive dogma. In fact, I see philosophy as an antidote to dogma because it demands argument. However, if all dialogue takes place in an echo-chamber, the argument never happens.

Social media allows alternative universes that are not only different but polar opposites. To give an example that arose out of the COVID pandemic: in one universe, the vaccines were saving lives, and in an alternative universe they were bioweapons causing deaths. The 2020 US presidential election created another example of parallel universes that were direct opposites. Climate change is another. In all these cases, which universe one inhabits depends on which source of information one trusts.

Authoritarian governments are well aware that the control of information allows emotional manipulation of the populace. In social media, the most emotive and often most extreme versions of events get the most traction. Plato’s response to tyranny and populist manipulation was to recommend ‘philosopher-kings’, but no one sees that as realistic. I spent a working lifetime in engineering, and I’ve learned that no single person has all the expertise, so we need to trust the people who have the expertise we lack. A good example is the weather forecast. We’ve learned to trust it as it delivers consistently accurate short-term forecasts. But it’s an exception, because news sources are rarely agenda-free.

I can’t see political biases disappearing – in fact, they seem to be becoming more extreme, and the people with the strongest opinions see themselves as the best-informed. Even science can be politicised, as with both the COVID pandemic and with climate change. The answer is not a philosopher-king, but the institutions we already have in place that study climate science and epidemiology. We actually have the expertise; but we don’t listen to it because its proponents are not famous social media influencers.

Mathematics, consciousness, reality

 I wish to emphasise the importance of following and listening to people you disagree with. (I might write another post on the pitfalls of ‘echo-chambers’ in social media, from which I’m not immune.)
 
I’ve been following Donald Hoffman ever since I reviewed an academic paper he wrote with Chetan Prakash called Objects of Consciousness, back in November 2016, though the paper was written in 2014 (so over 10 years ago). Back then, I have to admit, I found it hard to take him seriously, especially his views on evolution, and his go-to metaphor that objective reality was analogous to desktop icons on a computer.
 
His argument is similar to the idea that we live in a computer simulation, though he’s never said that, and I don’t think he believes we do. Nevertheless, he has compared reality to wearing a VR headset, which is definitely analogous to being in a computer simulation. As I have pointed out on other posts, I contend that we do create a model of reality in our ‘heads’, which is so ‘realistic’ that we all think it is reality. The thing is that our very lives depend on it being a very accurate ‘model’, so we can interact with the external reality that does exist outside our heads. This is one of my strongest arguments against Hoffman – reality can kill you, but simulations, including the ones we have when we sleep, which we call dreams, cannot.
 
So I’ve been following Hoffman, at least on YouTube, in the 8 years since I wrote that first critique. I read an article he wrote in New Scientist on evolution (can’t remember the date), which prompted me to write a letter-to-the-Editor, which was published. And whenever I come across him on YouTube: be it in an interview, a panel discussion or straight-to-video; I always watch and listen to what he has to say. What I’ve noticed is that he’s sharpened his scalpel, if I can use that metaphor, and that he’s changed his tack, if not his philosophical position. Which brings me to the reason for writing this post.
 
A year or two ago, I wrote a comment on one of his standalone videos, challenging what he said, and it was subsequently deleted, which is his prerogative. While I was critical, I don’t think I was particularly hostile – the tone was similar to a comment I wrote today on the video that prompted this discussion (see below).
 
Hoffman’s change of tack is not to talk about evolution at all, but spacetime and how it’s no longer ‘fundamental’. This allows him to argue that ‘consciousness’ is more fundamental than spacetime, via the medium of mathematics. And that’s effectively the argument he uses in this video, which, for brevity, I’ve distilled into one succinct sentence.
 
My approach, well known to anyone who regularly follows this blog, is that consciousness and mathematics are just as fundamental to reality as the physical universe, but not in the way that Hoffman argues. I’ve adopted, for better or worse, Roger Penrose’s triumvirate, which he likes to portray in an Escher-like diagram. 

 
I wouldn’t call myself a physicalist when it comes to consciousness, for the simple reason that I don’t believe we can measure it, and despite what Hoffman (and others) often claim, I’m not convinced that it will ever succumb to a mathematical model, in the way that virtually all physical theories do.
 
I left a comment on this video, which was hosted by the ‘Essentia Foundation’, so hopefully, it’s not deleted. Here it is:
 
I agree with him about Godel’s Theorem in its seminal significance to both maths and physics, which is that they are both neverending. However, when he says that ‘reality transcends any mathematical theory’ (3.00) I agree to a point, but I’d argue that mathematics transcends the Universe (known as mathematical Platonism); so in that sense, mathematics transcends reality.
 
The other point, which he never mentions, is that mathematical models of physical phenomena can be wrong – the best example being Ptolemy’s model of the solar system. String theory may well fall into that category – at this stage, we don’t know.
 
When he discusses consciousness being mathematical (4.30): ‘If consciousness is all there is, then mathematical structure is only about consciousness’; which is a premise dressed up as a conclusion, so circular.
 
The problem I’ve always had with Donald Hoffman’s idealism philosophy is that consciousness may exist independently of the Universe; it’s not possible for us to know. But within the Universe itself, evolutionary theory tells us that consciousness came late. Now, I know that he has his own theory of evolution to counter this, but that entails an argument that’s too long to address here.
 
Regarding his argument that spacetime is not fundamental, I know about Nima Arkani-Hamed and his work on amplituhedrons, and to quote: “This is a concrete example of a way in which the physics we normally associate with space-time and quantum mechanics arises from something more basic.” But the something more basic is mathematical, not physical. It’s possible that there was something before spacetime at the very birth of the Universe, but that’s speculative. All our cosmological theories are premised on spacetime.
 
I actually don’t think consciousness can be modelled mathematically, but its neurological underpinnings can, simply because they can be measured. Consciousness itself can’t be measured, only its neurological correlates. In other words, it can’t be measured outside of a brain, which is an object dependent on the Universe’s existence and not the other way round.

God and the problem of evil

 Philosophy Now (UK publication) that I’ve subscribed to for well over a decade now, is a bi-monthly (so 6 times a year) periodical, and it always has a theme. The theme for Dec 2024/Jan 2025 Issue 165 is The Return of God? In actuality, the articles inside covering that theme deal equally with atheism and theism, in quite diverse ways. It was an article titled A Critique of Pure Atheism (obvious allusion to Kant) by Andrew Likoudis that prompted me to write a Letter to the Editor, but I’m getting a little ahead of myself. Likoudis, by the way, is president of the Likoudis Legacy Foundation (an ecumenical research foundation), as well as the editor of 6 books, and studies communications at Towson University, which is in Maryland.
 
More than one article tackles the well-known ‘problem of evil’, and one of them even mentions Stephen Law’s not-so-well-known ‘Evil God’ argument. In the early days of this blog, which goes back 17 years, I spent a fair bit of time on Stephen’s blog where I indulged in discussions and arguments (with mostly other bloggers), most of which focused on atheism. In many of those arguments I found myself playing Devil’s advocate.
 
There is a more fundamental question behind the ‘existence of God’ question, which could be best framed as: Is evil necessary? I wrote a post on Evil very early in the life of this blog, in response to a book written by regular essayist for TIME magazine, Lance Morrow, titled Evil, An Investigation. Basically, I argued that evil is part of our evolutionary heritage, and is mostly, but not necessarily, manifest in our tribal nature, and our almost reflex tendency to demonise an outgroup, especially when things take a turn for the worse, either economically or socially or from a combination thereof. Historical examples abound. Some of the articles in Philosophy Now talk about ‘natural evil’, meaning natural disasters, which in the past (and sometimes in the present) are laid at the feet of God. In fact, so-called ‘acts of God’ have a legal meaning, when it comes to insurance claims and contractual issues (where I have some experience).
 
The thing is that ‘bad things happen’, with or without a God, with or without human agency. The natural world is more than capable of creating disasters, havoc and general destruction, with often fatal consequences. I’ve been reading the many articles in Philosophy Now somewhat sporadically, which is why, so far, I’ve only directly referenced one, being the one I responded to, while readily acknowledging that’s a tad unfair. As far as I can tell, no one mentions the Buddhist doctrine of the 4 Noble Truths, the first of which, basically says that everyone will experience some form of suffering in their lives. Even wealthy people get ill and are prone to diseases and have to deal with loss of loved ones. These experiences alone, are often enough reason for people to turn to religion. I’ve argued repeatedly and consistently that it’s how we deal with adversity that determines what sort of person we become and is what leads to what we call wisdom. It’s not surprising then, that we associate wisdom with age because, the longer one lives, the more adversity we experience and the more we hopefully learn from it.
 
One can’t talk about this without mentioning the role of fiction and storytelling. We are all drawn to stories from the ‘dark side’, which I’ve written about before. As a writer of fiction, I’m not immune to this. I’ve recently been watching a documentary series on the Batman movies, starting with Tim Burton, then Joel Schumacher and finally, Chris Nolan, all of which deal with the so-called dark side of this particular superhero, who is possibly unique among superheroes in flirting with the dark side of that universe. One of the ‘lessons’ gained from watching this doco is that Joel Schumacher’s sequel, Batman & Robin, which arguably attempted to eschew the dark side for a much lighter tone, all but destroyed the franchise. I confess I never saw that movie – I was turned off by the trailer (apparently for good reason). I’m one of those who thinks that Nolan’s The Dark Knight is the definitive Batman movie, with Heath Ledger’s Joker being one of the most iconic villain depictions ever.
 
A detour, but relevant. I’ve noticed that my own fiction has become darker, where I explore dystopian worlds – not unusual in science fiction. I’m reminded of a line from a Leonard Cohen song, ‘There’s a crack in everything; that’s how the light gets in’. I often think that applies to our lives, and it certainly applies to the fiction that I write. I create scenarios of potential doom and oppression, but there is always a light that emerges from somewhere that provides salvation and hope and sometimes redemption. The thing is that we need dark for the light to emerge and that is equally true of life. It’s not hard to imagine life as a test that we have to partake in, and I admit that I find this sometimes being manifest in my dreams as well as my fiction.
 
Having said that, I have an aversion to the idea that there is an afterlife with rewards and punishments dependant on how we live this life. For a start, we are not all tested equally. I only have to look at my father who was tested much more harshly than me, and like me, vehemently eschewed the idea of a God who punished his ‘children’ with everlasting torment. Hell and Heaven, like God himself, are projections when presented in this context: human constructs attempting to make sense of an apparently unjust world; and finding a correspondence in the Buddhist concept of reincarnation and karma, which I also reject. I was brought up with a Christian education, but at some point, I concluded that the biblical God was practically no more moral than the Devil – one only has to look at the story of Job, whom God effectively tortured to win a bet with the Devil.
 
If I can jump back to the previous paragraph before the last, I think we have to live with the consequences of our actions, and I’ve always imagined that I judge my life on my interactions with others rather than my achievements and failures. I don’t see death as an escape or transition, but quite literally an end, where, most significantly, I can no longer affect the world. My own view is that I’m part of some greater whole that not only includes humanity but the greater animal kingdom, and having the unique qualities of comprehension that other creatures don’t have, I have a special responsibility to them for their welfare as well as my own.
 
In this picture, I see God as a projection of my particular ideal, which is not reflected in any culture I’m aware of. I sometime think the Hindu concept of Brahman (also not referenced in Philosophy Now, from what I’ve read thus far) as a collective ‘mind’, which appealed to Erwin Schrodinger, in particular, comes closest to my idea of a God, which would mean that the problem of evil is axiomatically subsumed therein – we get the God we deserve.
 
This is the letter I wrote, which may or may not get published in a future edition:
 
I read with interest Andrew Likoudis’s essay, A Critique of Pure Atheism, because I think, like many (both theists and atheists), he conflates different concepts of God. In fact, as Karen Armstrong pointed out in her book, The History of God, there are 2 fundamentally different paths for believing in God. One path is via a mystical experience and the other path is a cerebral rationalisation of God as the Creator of the Universe and everything in it, which I’d call the prime raison d’etre of existence. In other words, without God there would not only be no universe, but no reason for it to exist. I believe Likoudis’s essay is a formulation of this latter concept, even though he expresses it in different terms.

Likoudis makes the valid point that empirical science is not the correct 'instrument', if I can use that term in this context, for ‘proving’ the existence of God, and for good reason. Raymond Tallis has pointed out, more than once, that science can only really deal with entities that can be measured or quantified, which is why mathematics plays such an important, if not essential, role in a lot of science; and physics, in particular.
 
Metaphysics, almost by definition, is outside the empiricist’s domain. I would argue that this includes consciousness, and despite measurable correlates with neuronal activity, consciousness itself can’t be measured. The only reason we believe someone else (not to mention other creatures) have consciousness is that their observed behaviour is similar to our own. Conscious experience is what we call mind, and mind is arguably the only connection between the Universe and God, which brings us closer to Armstrong’s argument for God based on mystical experience.

So I think the argument for God, as an experience similar to mind, has more resonance for believers than an argument for God as a Creator with mythical underpinnings. A point that Likoudis doesn't mention is that all the Gods of literature and religion have cultural origins, whereas an experience of God is purely subjective and can’t be shared. The idea that this experience of God is also the creator of the entire universe is a non sequitur. However, if one goes back to God being the raison d’etre for the Universe, then maybe God is the end result rather than its progenitor.

 
 
Footnote: I wrote a post back in 2021 in response to AC Grayling’s book, The God Argument, which is really a polemic against theism in general. You can judge for yourself whether my views are consistent or have changed.

Is there a cosmic purpose? Is our part in it a chimera?

 I’ve been procrastinating about writing this post for some time, because it comes closest to a ‘theory’ of Life, the Universe and Everything. ‘Theory’ in this context being a philosophical point of view, not a scientifically testable theory in the Karl Popper sense (it can’t be falsified), but using what science we currently know and interpreting it to fit a particular philosophical prejudice, which is what most scientists and philosophers do even when they don’t admit it.
 
I’ve been watching a lot of YouTube videos, some of which attempt to reconcile science and religion, which could be considered a lost cause, mainly because there is a divide going back to the Dark Ages, which the Enlightenment never bridged despite what some people might claim. One of the many videos I watched was a moderated discussion between Richard Dawkins and Jordan Peterson, which remained remarkably civil, especially considering that Peterson really did go off on flights of fancy (from my perspective), comparing so-called religious ‘truths’ with scientific ‘truths’. I thought Dawkins handled it really well, because he went to pains not to ridicule Peterson, while pointing out fundamental problems with such comparisons.
 
I’m already going off on tangents I never intended, but I raise it because Peterson makes the point that science actually arose from the Judea-Christian tradition – a point that Dawkins didn’t directly challenge, but I would have. I always see the modern scientific enterprise, if I can call it that, starting with Copernicus, Galileo and Kepler, but given particular impetus by Newton and his contemporary and rival, Leibniz. It so happens that they all lived in Europe when it was dominated by Christianity, but the real legacy they drew on was from the Ancient Greeks with a detour into Islam where it acquired Hindu influences, which many people conveniently ignore. In particular, we adopted Hindu-Arabic arithmetic, incorporating zero as a decimal place-marker, without which physics would have been stillborn.
 
Christianity did its best to stop the scientific enterprise: for example, when it threatened Galileo with the inquisition and put him under house arrest. Modern science evolved despite Christianity, not because of it. And that’s without mentioning Darwin’s problems, which still has ramifications today in the most advanced technological nation in the world.
 
A lengthy detour, but only slightly off-topic. There is a mystery at the heart of everything on the very edge of our scientific understanding of the world that I believe is best expressed by Paul Davies, but was also taken up by Stephen Hawking, of all people, towards the end of his life. I say, ‘of all people’, because Hawking was famously sceptical of the role of philosophy, yet, according to his last collaborator, Thomas Hertog, he was very interested in the so-called Big Questions, and like Davies, was attracted to John Wheeler’s idea of a cosmic-scale quantum loop that attempts to relate the end result of the Universe to its beginning.
 
Implicit in this idea is that the Universe has a purpose, which has religious connotations. So I want to make that point up front and add that there is No God Required. I agree with Davies that science neither proves nor disproves the existence of God, which is very much a personal belief, independent of any rationalisation one can make.
 
I wrote a lengthy post on Hawking’s book, The Grand Design, back in 2020 (which he cowrote with Leonard Mlodinow). I will quote from that post to highlight the point I raised 2 paragraphs ago: the link between present and past.
 
Hawking contends that the ‘alternative histories’ inherent in Feynman’s mathematical method, not only affect the future but also the past. What he is implying is that when an observation is made it determines the past as well as the future. He talks about a ‘top down’ history in lieu of a ‘bottom up’ history, which is the traditional way of looking at things. In other words, cosmological history is one of many ‘alternative histories’ (his terminology) that evolve from QM.
 
Then I quote directly from Hawking’s text:
 
This leads to a radically different view of cosmology, and the relation between cause and effect. The histories that contribute to the Feynman sum don’t have an independent existence, but depend on what is being measured. We create history by our observation, rather than history creating us (my emphasis).
 
One can’t contemplate this without considering the nature of time. There are in fact 2 different experiences we have of time, and that has created debate among physicists as well as philosophers. The first experience is simply observational. Every event with a causal relationship that is separated by space is axiomatically also separated by time, and this is a direct consequence of the constant speed of light. If this wasn’t the case, then everything would literally happen at once. So there is an intrinsic relationship between time and light, which Einstein had the genius to see: was not just a fundamental law of the Universe; but changed perceptions of time and space for different observers. Not only that, his mathematical formulations of this inherent attribute, led him to the conclusion that time itself was fluid, dependent on an observer’s motion as well as the gravitational field in which they happened to be.
 
I’m going to make another detour because it’s important and deals with one of the least understood aspects of physics. One of the videos I watched that triggered this very essay was labelled The Single Most Important Experiment in Physics, which is the famous bucket experiment conducted by Newton, which I’ve discussed elsewhere. Without going into details, it basically demonstrates that there is a frame of reference for the entire universe, which Newton called absolute space and Einstein called absolute spacetime. Penrose also discusses the importance of this concept, because it means that all relativistic phenomena take place against a cosmic background. It’s why we can determine the Earth’s velocity with respect to the entire universe by measuring the Doppler shift against the CMBR (cosmic microwave background radiation).
 
Now, anyone with even a rudimentary knowledge of relativity theory knows that it’s not just time that’s fluid but also space. But, as Kip Thorne has pointed out, mathematically we can’t tell if it’s the space that changes in dimension or the ruler used to measure it. I’ve long contended that it’s the ruler, which can be the clock itself. We can use a clock to measure distance and if the clock changes, which relativity tell us it does, then it’s going to measure a different distance to a stationary observer. By stationary, I mean one who is travelling at a lesser speed with respect to the overall CMBR.
 
So what is the other aspect of time that we experience? It’s the very visceral sensation we all have that time ‘flows’, because we all ‘sense’ its ‘passing’. And this is the most disputed aspect of time, that many physicists tell us is an illusion, including Davies. Some, like Sabine Hossenfelder, are proponents of the ‘block universe’, first proposed by Einstein, whereby the future already exists like the past, which is why both Hossenfelder and Einstein believed in what is now called superdeterminism – everything is predetermined in advance – which is one of the reasons that Einstein didn’t like the philosophical ramifications of quantum mechanics (I’ll get to his ‘spooky action at a distance’ later).
 
Davies argues that the experience of time passing is a psychological phenomenon and the answer will be found in neuroscience, not physics. And this finally brings consciousness into the overall scheme of things. I’ve argued elsewhere that, without consciousness, the Universe has no meaning and no purpose. Since that’s the point of this dissertation, it can be summed up with an aphorism from Wheeler.
 
The Universe gave rise to consciousness and consciousness gives the Universe meaning.
 
I like to cite Schrodinger from his lectures on Mind and Matter appended to his tome, What is Life? Consciousness exists in a constant present, and I argue that it’s the only thing that does (the one possible exception is a photon of light, for which time is zero). As I keep pointing out, this is best demonstrated every time someone takes a photo: it freezes time, or more accurately, it creates an image frozen in time; meaning it’s forever in our past, but so is the event that it represents.
 
The flow of time we all experience is a logical consequence of this. In a way, Davies is right: it’s a neurological phenomenon, in as much as consciousness seems to ‘emerge’ from neuronal activity. But I’m not sure Davies would agree with me – in fact, I expect he wouldn’t.
 
Those who have some familiarity with my blog, may see a similarity between these 2 manifestations of time and my thesis on Type A time and Type B time (originally proposed by J.M.E. McTaggart, 1906); the difference between them, in both cases, being the inclusion of consciousness.
 
Now I’m going to formulate a radical idea, which is that in Type B time (the time without consciousness), the flow of time is not experienced but there are chains of causal events. And what if all the possible histories are all potentially there in the same way that future possible histories are, as dictated by Feynman’s model. And what if the one history that we ‘observe’, going all the way back to the pattern in the CMBR (our only remnant relic of the Big Bang), only became manifest when consciousness entered the Universe. And when I say ‘entered’ I mean that it arose out of a process that had evolved. Davies, and also Wheeler before him, speculated that the ‘laws’ of nature we observe have also evolved as part of the process. But what if those laws only became frozen in the past when consciousness finally became manifest. This is the backward-in-time quantum loop that Wheeler hypothesised.
 
I contend that QM can only describe the future (an idea espoused by Feynman’s collaborator, Freeman Dyson), meaning that Schrodinger’s equation can only describe the future, not the past. Once a ‘measurement’ is made, it no longer applies. Penrose explains this best, and has his own argument that the ‘collapse’ of the wave function is created by gravity. Leaving that aside, I argue that the wave function only exists in our future, which is why it’s never observed and why Schrodinger’s equation can’t be applied to events that have already happened. But what if it was consciousness that finally determined which of many past paths became the reality we observe. You can’t get more speculative than that, but it provides a mechanism for Wheeler’s ‘participatory universe’ that both Davies and Hawking found appealing.
 
I’m suggesting that the emergence of consciousness changed the way time works in the Universe, in that the past is now fixed and only the future is still open.
 
Another video I watched also contained a very radical idea, which is that spacetime is created like a web into the future (my imagery). The Universe appears to have an edge in time but not in space, and this is rarely addressed. It’s possible that space is being continually created with the Universe’s expansion – an idea explored by physicist, Richard Muller – but I think it’s more likely that the Universe is Euclidean, meaning flat, but bounded. We may never know.
 
But if the Universe has an edge in time, how does that work? I think the answer is quantum entanglement, though no one else does. Everyone agrees that entanglement is non-local, meaning it’s not restricted by the rules of relativity, and it’s not spatially dependent. I speculate that quantum entanglement is the Universe continually transitioning from a quantum state to a classical physics state. This idea is just as heretical as the one I proposed earlier, and while Einstein would call it ‘spooky action at a distance’, it makes sense, because in quantum cosmology, time mathematically disappears. And it disappears because you can’t ‘see’ the future of the Universe, even in principle.

Addendum 1: This excerpt from a panel discussion shows how this debate is unresolved even among physicists. The first speaker, Avshalom Elitzur (who is also referenced in one of the videos linked in the 2nd last paragraph of the main text) probably comes closest to expressing my viewpoint.

In effect, he describes what I expound on in my post, though I'm sure he wouldn't agree with my more radical ideas - the role of consciousness and that entanglement is intrinsically linked to the edge of time for the whole universe. However, he does say, 'In some profound way the future does not exist'. 

Addendum 2: I came across this article in New Scientist, which you might not be able to access if you're not a subscriber (I have an online subscription). Basically, the author, Karmela Padavic-Callaghan, argues that 'classical time' arises from quantum 'entanglement', citing Alessandro Coppo. To quote:

This may mean that if we perceive the passage of time, then there is some entanglement woven into the physical world. And an observer in a universe devoid of entanglement – as some theories suggest ours was at its very beginning – would have seen nothing change. Everything would be static.

Why are we addicted to stories involving struggle?

This is something I’ve written about before, so what can I possibly add? Sometimes the reframing of a question changes the emphasis. In this case, I wrote a post on Quora in response to a fairly vague question, which I took more seriously than the questioner probably expected. As I said, I’ve dealt with these themes before, but adding a very intimate family story adds emotional weight. It’s a story I’ve related before, but this time I elaborate in order to give it the significance I feel it deserves.
 
What are some universal themes in fiction?
 
There is ONE universal theme that’s found virtually everywhere, and its appeal is that it provides a potential answer to the question: What is the meaning of life?

In virtually every story that’s been told, going as far back as Homer’s Odyssey and up to the latest superhero movie, with everything else in between (in the Western canon, at least), you have a protagonist who has to deal with obstacles, hardships and tribulations. In other words, they are tested, often in extremis, and we all take part vicariously to the point that it becomes an addiction.

There is a quote from the I Ching, which I think sums it up perfectly.

Adversity is the opposite of success, but it can lead to success if it befalls the right person.

Most of us have to deal with some form of adversity in life; some more so than others. And none of us are unaffected by it. Socrates’ most famous saying: The unexamined life is not worth living; is a variation on this theme. He apparently said it when he was forced to face his death; the consequences of actions he had deliberately taken, but for which he refused to show regret.

And yes, I think this is the meaning of life, as it is lived. It’s why we expect to become wiser as we get older, because wisdom comes from dealing with adversity, whether it ultimately leads to success or not.

When I write a story, I put my characters through hell, and when they come out the other side, they are invariably wiser if not triumphant. I’ve had characters make the ultimate sacrifice, just like Socrates, because they would prefer to die for a principle than live with shame.

None of us know how we will behave if we are truly tested, though sometimes we get a hint in our dreams. Stories are another way of imagining ourselves in otherwise unimaginable situations. My father is one who was tested firsthand in battle and in prison. The repercussions were serious, not just for him, but for those of us who had to live with him in the aftermath.

He had a recurring dream where there was someone outside the house whom he feared greatly – it was literally his worst nightmare. One night he went outside and confronted them, killing them barehanded. He told me this when I was much older, naturally, but it reminded me of when Luke Skywalker confronted his doppelganger in The Empire Strikes Back. I’ve long argued that the language of stories is the language of dreams. In this case, the telling of my father’s dream reminded me of a scene from a movie that made me realise it was more potent than I’d imagined.

I’m unsure how my father would have turned out had he not faced his demon in such a dramatic and conclusive fashion. It obviously had a big impact on him; he saw it as a form of test, which he believed he’d ultimately passed. I find it interesting that it was not something he confronted the first time he was made aware of it – it simply scared him to death. Stories are surrogate dreams; they serve the same purpose if they have enough emotional force.

Life itself is a test that we all must partake in, and stories are a way of testing ourselves against scenarios we’re unlikely to confront in real life.
