Freedom of the will is requisite for all other freedoms

 I’ve recently read 2 really good books on consciousness and the mind, as well as watch countless YouTube videos on the topic, but the title of this post reflects the endpoint for me. Consciousness has evolved, so for most of the Universe’s history, it didn’t exist, yet without it, the Universe has no meaning and no purpose. Even using the word, purpose, in this context, is anathema to many scientists and philosophers, because it hints at teleology. In fact, Paul Davies raises that very point in one of the many video conversations he has with Robert Lawrence Kuhn in the excellent series, Closer to Truth.
 
Davies is an advocate of a cosmic-scale ‘loop’, whereby QM provides a backwards-in-time connection which can only be determined by a conscious ‘observer’. This is contentious, of course, though not his original idea – it came from John Wheeler. As Davies points out, Stephen Hawking was also an advocate, premised on the idea that there are a number of alternative histories, as per Feynman’s ‘sum-over-histories’ methodology, but only one becomes reality when an ‘observation’ is made. I won’t elaborate, as I’ve discussed it elsewhere, when I reviewed Hawking’s book, The Grand Design.
 
In the same conversation with Kuhn, Davies emphasises the fact that the Universe created the means to understand itself, through us, and quotes Einstein: The most incomprehensible thing about the Universe is that it’s comprehensible. Of course, I’ve made the exact same point many times, and like myself, Davies makes the point that this is only possible because of the medium of mathematics.
 
Now, I know I appear to have gone down a rabbit hole, but it’s all relevant to my viewpoint. Consciousness appears to have a role, arguably a necessary one, in the self-realisation of the Universe – without it, the Universe may as well not exist. To quote Wheeler: The universe gave rise to consciousness and consciousness gives meaning to the Universe.
 
Scientists, of all stripes, appear to avoid any metaphysical aspect of consciousness, but I think it’s unavoidable. One of the books I cite in my introduction is Philip Ball’s The Book of Minds; How to Understand Ourselves and Other Beings; from Animals to Aliens. It’s as ambitious as the title suggests, and with 450 pages, it’s quite a read. I’ve read and reviewed a previous book by Ball, Beyond Weird (about quantum mechanics), which is equally as erudite and thought-provoking as this one. Ball is a ‘physicalist’, as virtually all scientists are (though he’s more open-minded than most), but I tend to agree with Raymond Tallis that, despite what people claim, consciousness is still ‘unexplained’ and might remain so for some time, if not forever.
 
I like an idea that I first encountered in Douglas Hofstadter’s seminal tome, Godel, Escher, Bach; an Eternal Golden Braid, that consciousness is effectively a loop, at what one might call the local level. By which I mean it’s confined to a particular body. It’s created within that body but then it has a causal agency all of its own. Not everyone agrees with that. Many argue that consciousness cannot of itself ‘cause’ anything, but Ball is one of those who begs to differ, and so do I. It’s what free will is all about, which finally gets us back to the subject of this post.
 
Like me, Ball prefers to use the word ‘agency’ over free will. But he introduces the term, ‘volitional decision-making’ and gives it the following context:

I believe that the only meaningful notion of free will – and it is one that seems to me to satisfy all reasonable demands traditionally made of it – is one in which volitional decision-making can be shown to happen according to the definition I give above: in short, that the mind operates as an autonomous source of behaviour and control. It is this, I suspect, that most people have vaguely in mind when speaking of free will: the sense that we are the authors of our actions and that we have some say in what happens to us. (My emphasis)

And, in a roundabout way, this brings me to the point alluded to in the title of this post: our freedoms are constrained by our environment and our circumstances. We all wish to be ‘authors of our actions’ and ‘have some say in what happens to us’, but that varies from person to person, dependent on ‘external’ factors.

Writing stories, believe it or not, had a profound influence on how I perceive free will, because a story, by design, is an interaction between character and plot. In fact, I claim they are 2 sides of the same coin – each character has their own subplot, and as they interact, their storylines intertwine. This describes my approach to writing fiction in a nutshell. The character and plot represent, respectively, the internal and external journey of the story. The journey metaphor is apt, because a story always has the dimension of time, which is visceral, and is one of the essential elements that separates fiction from non-fiction. To stretch the analogy, character represents free will and plot represents fate. Therefore, I tell aspiring writers the importance of giving their characters free will.

A detour, but not irrelevant. I read an article in Philosophy Now sometime back, about people who can escape their circumstances, and it’s the subject of a lot of biographies as well as fiction. We in the West live in a very privileged time whereby many of us can aspire to, and attain, the life that we dream about. I remember at the time I left school, following a less than ideal childhood, feeling I had little control over my life. I was a fatalist in that I thought that whatever happened was dependent on fate and not on my actions (I literally used to attribute everything to fate). I later realised that this is a state-of-mind that many people have who are not happy with their circumstances and feel impotent to change them.

The thing is that it takes a fundamental belief in free will to rise above that and take advantage of what comes your way. No one who has made that journey will accept the self-denial that free will is an illusion and therefore they have no control over their destiny.

I will provide another quote from Ball that is more in line with my own thinking:

…minds are an autonomous part of what causes the future to unfold. This is different to the common view of free will in which the world somehow offers alternative outcomes and the wilful mind selects between them. Alternative outcomes – different, counterfactual realities – are not real, but metaphysical: they can never be observed. When we make a choice, we aren’t selecting between various possible futures, but between various imagined futures, as represented in the mind’s internal model of the world… (emphasis in the original)

And this highlights a point I’ve made before: that it’s the imagination which plays the key role in free will. I’ve argued that imagination is one of the facilities of a conscious mind that separates us (and other creatures) from AI. Now AI can also demonstrate agency, and, in a game of chess, for example, it will ‘select’ from a number of possible ‘moves’ based on certain criteria. But there are fundamental differences. For a start, the AI doesn’t visualise what it’s doing; it’s following a set of highly constrained rules, within which it can select from a number of options, one of which will be the optimal solution. Its inherent advantage over a human player isn’t just its speed but its ability to compare a number of possibilities that are impossible for the human mind to contemplate simultaneously.

The other book I read was Being You; A New Science of Consciousness by Anil Seth. I came across Seth when I did an online course on consciousness through New Scientist, during COVID lockdowns. To be honest, his book didn’t tell me a lot that I didn’t already know. For example, that the world, we all see and think exists ‘out there’, is actually a model of reality created within our heads. He also emphasises how the brain is a ‘prediction-making’ organ rather than a purely receptive one. Seth mentions that it uses a Bayesian model (which I also knew about previously), whereby it updates its prediction based on new sensory data. Not surprisingly, Seth describes all this in far more detail and erudition than I can muster.

Ball, Seth and I all seem to agree that while AI will become better at mimicking the human mind, this doesn’t necessarily mean it will attain consciousness. Applications software, ChatGPT (for example), despite appearances, does not ‘think’ the way we do, and actually does not ‘understand’ what it’s talking or writing about. I’ve written on this before, so I won’t elaborate.

Seth contends that the ‘mystery’ of consciousness will disappear in the same way that the 'mystery of life’ has effectively become a non-issue. What he means is that we no longer believe that there is some ‘elan vital’ or ‘life force’, which distinguishes living from non-living matter. And he’s right, in as much as the chemical origins of life are less mysterious than they once were, even though abiogenesis is still not fully understood.

By analogy, the concept of a soul has also lost a lot of its cogency, following the scientific revolution. Seth seems to associate the soul with what he calls ‘spooky free will’ (without mentioning the word, soul), but he’s obviously putting ‘spooky free will’ in the same category as ‘elan vital’, which makes his analogy and associated argument consistent. He then says:

Once spooky free will is out of the picture, it is easy to see that the debate over determinism doesn’t matter at all. There’s no longer any need to allow any non-deterministic elbow room for it to intervene. From the perspective of free will as a perceptual experience, there is simply no need for any disruption to the causal flow of physical events. (My emphasis)

Seth differs from Ball (and myself) in that he doesn’t seem to believe that something ‘immaterial’ like consciousness can affect the physical world. To quote:

But experiences of volition do not reveal the existence of an immaterial self with causal power over physical events.

Therefore, free will is purely a ‘perceptual experience’. There is a problem with this view that Ball himself raises. If free will is simply the mind observing effects it can’t cause, but with the illusion that it can, then its role is redundant to say the least. This is a view that Sabine Hossenfelder has also expressed: that we are merely an ‘observer’ of what we are thinking.

Your brain is running a calculation, and while it is going on you do not know the outcome of that calculation. So the impression of free will comes from our ‘awareness’ that we think about what we do, along with our inability to predict the result of what we are thinking.

Ball makes the point that we only have to look at all the material manifestations of human intellectual achievements that are evident everywhere we’ve been. And this brings me back to the loop concept I alluded to earlier. Not only does consciousness create a ‘local’ loop, whereby it has a causal effect on the body it inhabits but also on the external world to that body. This is stating the obvious, except, as I’ve mentioned elsewhere, it’s possible that one could interact with the external world as an automaton, with no conscious awareness of it. The difference is the role of imagination, which I keep coming back to. All the material manifestations of our intellect are arguably a result of imagination.

One insight I gained from Ball, which goes slightly off-topic, is evidence that bees have an internal map of their environment, which is why the dance they perform on returning to the hive can be ‘understood’ by other bees. We’ve learned this by interfering in their behaviour. What I find interesting is that this may have been the original reason that consciousness evolved into the form that we experience it. In other words, we all create an internal world that reflects the external world so realistically, that we think it is the actual world. I believe that this also distinguishes us (and bees) from AI. An AI can use GPS to navigate its way through the physical world, as well as other so-called sensory data, from radar or infra-red sensors or whatever, but it doesn’t create an experience of that world inside itself.

The human mind seems to be able to access an abstract world, which we do when we read or watch a story, or even write one, as I have done. I can understand how Plato took this idea to its logical extreme: that there is an abstract world, of which the one we inhabit is but a facsimile (though he used different terminology). No one believes that today – except, there is a remnant of Plato’s abstract world that persists, which is mathematics. Many mathematicians and physicists (though not all) treat mathematics as a neverending landscape that humans have the unique capacity to explore and comprehend. This, of course, brings me back to Davies’ philosophical ruminations that I opened this discussion with. And as he, and others (like Einstein, Feynman, Wigner, Penrose, to name but a few) have pointed out: the Universe itself seems to follow specific laws that are intrinsically mathematical and which we are continually discovering.

And this closes another loop: that the Universe created the means to comprehend itself, using the medium of mathematics, without which, it has no meaning. Of purpose, we can only conjecture.

Common sense; uncommonly agreed upon

 The latest New Scientist (28 Sep., 2024) had an article headlined Uncommon Sense, written by Emma Young (based in Sheffield, UK) which was primarily based on a study done by Duncan Watts and Mark Whiting at the University of Pennsylvania. I wasn’t surprised to learn that ‘common sense’ is very subjective, although she pointed out that most people think the opposite: that it’s objective. I’ve long believed that common sense is largely culturally determined, and in many cases, arises out of confirmation bias, which the article affirmed with references to the recent COVID pandemic and the polarised responses this produced; where one person’s common sense was another person’s anathema.
 
Common sense is something we mostly imbibe through social norms, though experience tends to play a role long term. Common sense is often demonstrated, though not expressed, as a heuristic, where people with expertise develop heuristics that others outside their field wouldn’t even know about. This is a point I’ve made before, without using the term common sense. In other words, common sense is contextual in a way that most of us don’t consider.
 
Anyone with an interest in modern physics (like myself) knows that our common sense views on time and space don’t apply in the face of Einstein’s relativity theory. In fact, it’s one of the reasons that people struggle with it (Including me). Quantum mechanics with phenomena like superposition, entanglement and Heisenberg’s Uncertainty Principle also play havoc with our ‘common sense’ view of the world. But this is perfectly logical when one considers that we never encounter these ‘effects’ in our everyday existence, so they can be largely, if not completely, ignored. The fact that the GPS on your phone requires relativistic corrections and that every device you use (including said phone) are dependent on QM dynamics doesn’t change this virtually universal viewpoint.
 
I’ve just finished reading an excellent, albeit lengthy, book by Philip Ball titled ambitiously, if not pretentiously, The Book of Minds. I can honestly say it’s the best book I’ve read on the subject, but that’s a topic for a future post. The reason I raise it in this context, is because throughout I kept using AI as a reference point for appreciating what makes minds unique. You see, AI comes closest to mimicking the human mind, yet it’s nowhere near it, though others may disagree. As I said, it’s a topic for another post.
 
I remember coming up with my own definition of common sense many years ago, when I saw it as something that evolves over time, based on experience. I would contend that our common sense view on a subject changes, whether it be through the gaining of expertise in a specific field (as I mentioned above) or just our everyday encounters. A good example, that most of us can identify with, is driving a car. Notice how, over time, we develop skills and behaviours that have helped us to avoid accidents, some of which have arisen because of accidents.
 
And a long time ago, before I became a blogger, and didn’t even consider myself a philosopher, it occurred to me that AI could also develop something akin to common sense based on learning from its mistakes. Self-driving cars being a case-in-point.
 
According to the New Scientist article, the researchers, Watts and Whiting, claim that there is no correlation between so-called common sense and IQ. Instead, they contend that there is a correlation between a ‘consensual common sense’ (my term) and ‘Reading the Mind in the Eyes’ (their terminology). In other words, the ability to ‘read’ emotions is a good indicator for the ability to determine what’s considered ‘common sense’ for the majority of a cultural group (if I understand them correctly). This infers that common sense is a consensual perception, based on cultural norms, which is what I’ve always believed. This might be a bit simplistic, and an example of confirmation bias (on my part), but I’d be surprised if common sense didn’t morph between cultures in the same way it becomes modified by expertise in a particular field. So the idea of a universal, objective common sense is as much a chimera as objective morality, which is also more dependent on social norms than most people acknowledge.
 
 
Footnote: it’s worth reading the article in New Scientist (if accessible), because it provides a different emphasis and a different perspective, even though it largely draws similar conclusions to myself.

Prima Facie; the play

 I went and saw a film made of a live performance of this highly rated play, put on by the National Theatre at the Harold Pinter Theatre in London’s West End in 2022. It’s a one-hander, played by Jodie Comer, best known as the quirky assassin with a diabolical sense of humour, in the black comedy hit, Killing Eve. I also saw her in Ridley Scott’s riveting and realistically rendered film, The Last Duel, set in mediaeval France, where she played alongside Matt Damon, Adam Driver and an unrecognisable Ben Affleck. The roles that Comer played in those 2 screen mediums, couldn’t be more different.
 
Theatre is more unforgiving than cinema, because there are no multiple takes or even a break once the curtain’s raised; a one-hander, even more so. In the case of Prima Facie, Comer is on the stage a full 90mins, and even does costume-changes and pushing around her own scenery unaided, without breaking stride. It’s such a tour de force performance, as the Financial Times put it; I’d go so far as to say it’s the best acting performance I’ve ever witnessed by anyone. It’s such an emotionally draining role, where she cries and even breaks into a sweat in one scene, that I marvel she could do it night-after-night, as I assume she did.
 
And I’ve yet to broach the subject matter, which is very apt, given the me-too climate, but philosophically it goes deeper than that. The premise for the entire play, which is even spelt out early on, in case you’re not paying attention, is the difference between truth and justice, and whether it matters. Comer’s character, Tessa, happens to experience it from both sides, which is what makes this so powerful.
 
She’s a defence barrister, who specialises in sexual-assault cases, where, as she explains very early on, effectively telling us the rules of the game: no one wins or loses; you either come first or second. In other words, the barristers and those involved in the legal profession, don’t see the process the same way that you and I do, and I can understand that – to get emotionally involved makes it very stressful.

In fact, I have played a small role in this process in a professional capacity, so I’ve seen this firsthand. But I wasn’t dealing with rape cases or anything involving violence, just contractual disputes where millions of dollars could be at stake. My specific role was to ‘prepare evidence’ for lawyers for either a claim or the defence of a claim or possibly a counter-claim, and I quickly realised the more dispassionate one is, the more successful one is likely to be. I also realised that the lawyers I was supporting in one case could be on the opposing side in the next one, so you don’t get personal.
 
So, I have a small insight into this world, and can appreciate why they see it as a game, where you ‘win or come second’. But in Prima Facie, Tess goes through this very visceral and emotionally scarifying transformation where she finds herself on the receiving end, and it’s suddenly very personal indeed.
 
Back in 2015, I wrote a mini-400-word essay, in answer to one of those Question of the Month topics that Philosophy Now like to throw open to amateur wannabe philosophers, like myself. And in this case, it was one that was selected for publication (among 12 others), from all around the Western globe. I bring this up, because I made the assertion that ‘justice without truth is injustice’, and I feel that this is really what Prima Facie is all about. At the end of the play, with Tess now having the perspective of the victim (there is no other word), it does become a matter of winning or losing, because, not only her career and future livelihood, but her very dignity, is now up for sacrifice.
 
I watched a Q&A programme on Australia’s ABC some years ago, where this issue was discussed. Every woman on the panel, including one from the righteous right (my coinage), had a tale to tell about discrimination or harassment in a workplace situation. But the most damming testimony came from a man, who specialised in representing women in sexual assault cases, and he said that in every case, their doctors tell them not to proceed because it will destroy their health; and he said: they’re right. I was reminded of this when I watched this play.
 
One needs to give special mention to the writer, Suzie Miller, who is an Aussie as it turns out, and as far as 6 degrees of separation go, I happen to know someone who knows her father. Over 5 decades I’ve seen some very good theatre, some of it very innovative and original. In fact, I think the best theatre I’ve seen has invariably been something completely different, unexpected and dare-I-say-it, special. I had a small involvement in theatre when I was still very young, and learned that I couldn’t act to save myself. Nevertheless, my very first foray into writing was an attempt to write a play. Now, I’d say it’s the hardest and most unforgiving medium of storytelling to write for. I had a friend who was involved in theatre for some decades and even won awards. She passed a couple of years ago and I miss her very much. At her funeral, she was given a standing ovation, when her coffin was taken out; it was very moving. I can’t go to a play now without thinking about her and wishing I could discuss it with her.

Science and religion meet at the boundary of humanity’s ignorance

 I watched a YouTube debate (90 mins) between Sir Roger Penrose and William Lane Craig, and, if I’m honest, I found it a bit frustrating because I wish I was debating Craig instead of Penrose. I also think it would have been more interesting if Craig debated someone like Paul Davies, who is more philosophically inclined than Penrose, even though Penrose is more successful as a scientist, and as a physicist, in particular.
 
But it was set up as an atheist versus theist debate between 2 well known personalities, who were mutually respectful and where there was no animosity evident at all. I confess to having my own biases, which would be obvious to any regular reader of this blog. I admit to finding Craig arrogant and a bit smug in his demeanour, but to be fair, he was on his best behaviour, and perhaps he’s matured (or perhaps I have) or perhaps he adapts to whoever he’s facing. When I call it a debate, it wasn’t very formal and there wasn’t even a nominated topic. I felt the facilitator or mediator had his own biases, but I admit it would be hard to find someone who didn’t.
 
Penrose started with his 3 worlds philosophy of the physical, the mental and the abstract, which has long appealed to me, though most scientists and many philosophers would contend that the categorisation is unnecessary, and that everything is physical at base. Penrose proposed that they present 3 mysteries, though the mysteries are inherent in the connections between them rather than the categories themselves. This became the starting point of the discussion.
 
Craig argued that the overriding component must surely be ‘mind’, whereas Penrose argued that it should be the abstract world, specifically mathematics, which is the position of mathematical Platonists (including myself). Craig pointed out that mathematics can’t ‘create’ the physical, (which is true) but a mind could. As the mediator pointed out (as if it wasn’t obvious) said mind could be God. And this more or less set the course for the remainder of the discussion, with a detour to Penrose’s CCC theory (Conformal Cyclic Cosmology).
 
I actually thought that this was Craig’s best argument, and I’ve written about it myself, in answer to a question on Quora: Did math create the Universe? The answer is no, nevertheless I contend that mathematics is a prerequisite for the Universe to exist, as the laws that allowed the Universe to evolve, in all its facets, are mathematical in nature. Note that this doesn’t rule out a God.
 
Where I would challenge Craig, and where I’d deviate from Penrose, is that we have no cognisance of who this God is or even what ‘It’ could be. Could not this God be the laws of the Universe themselves? Penrose struggled with this aspect of the argument, because, from a scientific perspective, it doesn’t tell us anything that we can either confirm or falsify. I know from previous debates that Craig has had, that he would see this as a win. A scientist can’t refute his God’s existence, nor can they propose an alternative, therefore it’s his point by default.
 
This eventually led to a discussion on the ‘fine-tuning’ of the Universe, which in the case of entropy, is what led Penrose to formulate his CCC model of the Universe. Of course, the standard alternative is the multiverse and the anthropic principle, which, as Penrose points out, is also applicable to his CCC model, where you have an infinite sequence of universes as opposed to an infinity of simultaneous ones, which is the orthodox response among cosmologists.
 
This is where I would have liked to have seen Paul Davies respond, because he’s an advocate of John Wheeler’s so-called ‘participatory Universe’, which is effectively the ‘strong anthropic principle’ as opposed to the ‘weak anthropic principle’. The weak anthropic principle basically says that ‘observers’ (meaning us) can only exist in a universe that allows observers to exist – a tautology. Whereas the strong anthropic principle effectively contends that the emergence of observers is a necessary condition for the Universe to exist (the observers don’t have to be human). Basically, Wheeler was an advocate of a cosmic, acausal (backward-in-time) link from conscious observers to the birth of the Universe. I admit this appeals to me, but as Craig would expound, it’s a purely metaphysical argument, and so is the argument for God.
 
The other possibility that is very rarely expressed, is that God is the end result of the Universe rather than its progenitor. In other words, the ‘mind’ that Craig expounded upon is a consequence of all of us. This aligns more closely with the Hindu concept of Atman or a Buddhist concept of collective karma – we get the God we deserve. Erwin Schrodinger, who studied the Upanishads, discusses Atman as a pluralistic ‘mind’ (in What is Life?). My point would be that the Judea-Christian-Islamic God does not have a monopoly on Craig’s overriding ‘mind’ concept.
 
A recurring theme on this blog is that there will always be mysteries – we can never know everything – and it’s an unspoken certitude that there will forever be knowledge beyond our cognition. The problem that scientists sometimes have, but are reluctant to admit, is that we can’t explain everything, even though we keep explaining more by the generation. And the problem that theologians sometimes have is that our inherent ignorance is neither ‘proof’ nor ‘evidence’ that there is a ‘creator’ God.
 
I’ve argued elsewhere that a belief in God is purely a subjective and emotional concept, which one then rationalises with either cultural references or as an ultimate explanation for our existence.

Addendum: I like this quote, albeit out of context, from Spinoza:: "The sum of the natural and physical laws of the universe and certainly not an individual entity or creator".

How scale demonstrates that mathematics is intrinsically entailed in the Universe

 I momentarily contemplated another title: Is the Planck limit an epistemology or an ontology? Because that’s basically the topic of a YouTube video that’s the trigger for this post. I wrote a post some time ago where I discussed whether the Universe is continuous or discrete, and basically concluded that it was continuous. Based on what I’ve learned from this video, I might well change my position. But I should point out that my former opposition was based more on the idea that it could be quantised into ‘bits’ of information, whereas now I’m willing to acknowledge that it could be granular at the Planck scale, which I’ll elaborate on towards the end. I still don’t think that the underlying reality of the Universe is in ‘bits’ of information, therefore potentially created and operated by a computer.
 
Earlier this year, I discussed the problem of reification of mathematics so I want to avoid that if possible. By reification, I mean making a mathematical entity reality. Basically, physics works by formulating mathematical models that we then compare to reality through observations. But as Freeman Dyson pointed out, the wave function (Ψ), for example, is a mathematical entity and not a physical entity, which is sometimes debated. The fact is that if it does exist physically, it’s never observed, and my contention is that it ‘exists’ in the future; a view that is consistent with Dyson’s own philosophical viewpoint that QM can only describe the future and not the past.
 
And this brings me to the video, which has nothing to say about wave functions or reified mathematical entities, but uses high school mathematics to explore such esoteric and exotic topics as black holes and quantum gravity. There is one step involving integral calculus, which is about as esoteric as the maths becomes, and if you allow that 1/∞ = 0, it leads to the formula for the escape velocity from any astronomical body (including Earth). Note that the escape velocity literally allows an object to escape a gravitational field to infinity (∞). And the escape velocity for a black hole is c (the speed of light).
 
All the other mathematics is basic algebra using some basic physics equations, like Newton’s equation for gravity, Planck’s equation for energy, Heisenberg’s Uncertainty Principle using Planck’s Constant (h), Einstein’s famous equation for the equivalence of energy and mass, and the equation for the Coulomb Force between 2 point electric charges (electrons). There is also the equation for the Schwarzschild radius of a black hole, which is far easier to derive than you might imagine (despite the fact that Schwarzschild originally derived it from Einstein’s field equations).
 
Back in May 2019, I wrote a post on the Universe’s natural units, which involves the fundamental natural constants, h, c and G. This was originally done by Planck himself, which I describe in that post, while providing a link to a more detailed exposition. In the video (embedded below), the narrator takes a completely different path to deriving the same Planck units before describing a method that Planck himself would have used. In so doing, he explains how at the Planck level, space and time are not only impossible to observe, even in principle, but may well be impossible to remain continuous in reality. You need to watch the video, as he explains it far better than I can, just using high school mathematics.
 
Regarding the title I chose for this post, Roger Penrose’s Conformal Cyclic Cosmology (CCC) model of the Universe, exploits the fact that a universe without matter (just radiation) is scale invariant, which is essential for the ‘conformal’ part of his theory. However, that all changes when one includes matter. I’ve argued in other posts that different forces become dominant at different scales, from the cosmological to the subatomic. The point made in this video is that at the Planck scale all the forces, including gravity, become comparable. Now, as I pointed out at the beginning, physics is about applying mathematical models and comparing them to reality. We can’t, and quite possibly never will, be able to observe reality at the Planck scale, yet the mathematics tells us that it’s where all the physics we currently know is compatible. It tells me that not only is the physics of the Universe scale-dependent, but it's also mathematically dependent (because scale is inherently mathematical). In essence, the Universe’s dynamics are determined by mathematical parameters at all scales, including the Planck scale.
 
Note that the mathematical relationships in the video use ~ not = which means that they are approximate, not exact. But this doesn’t detract from the significance that 2 different approaches arrive at the same conclusion, which is that the Planck scale coincides with the origin of the Universe incorporating all forces equivalently.
 
 
Addendum: I should point out that Viktor T Toth, who knows a great deal more about this than me, argues that there is, in fact, no limit to what we can measure in principle. Even the narrator in the video frames his conclusion cautiously and with caveats. In other words, we are in the realm of speculative physics. Nevertheless, I find it interesting to contemplate where the maths leads us.

When truth becomes a casualty, democracy is put at risk

 You may know of Raimond Gaita as the author of Romulus, My Father, a memoir of his childhood, as the only child of postwar European parents growing up in rural Australia. It was turned into a movie directed by Richard Roxborough (his directorial debut) and starring Eric Bana. What you may not know is that Raimond Gaita is also a professor of philosophy who happens to live in the same metropolis as me, albeit in different suburbs.
 
I borrowed his latest tome, Justice and Hope; Essays, Lectures and Other Writings, from my local library (published last year, 2023), and have barely made a dent in the 33 essays, unequally divided into 6 parts. So far, I’ve read the 5 essays in Part 1: An Unconditional Love of the World, and just the first essay of Part 2: Truth and Judgement, which is titled rather provocatively, The Intelligentsia in the Age of Trump. Each essay heading includes the year it was written, and the essay on the Trump phenomenon (my term, not his) was written in 2017, so after Trump’s election but well before his ignominious attempt to retain power following his election defeat in 2020. And, of course, he now has more stature and influence than ever, having just won the Presidential nomination from the Republican Party for the 2024 election, which is only months away as I write.
 
Gaita doesn’t write like an academic in that he uses plain language and is not afraid to include personal anecdotes if he thinks they’re relevant, and doesn’t pretend that he’s nonpartisan in his political views. The first 5 essays regarding ‘an unconditional love of the world’ all deal with other writers and postwar intellects, all concerned with the inhumane conditions that many people suffered, and some managed to survive, during World War 2. This is confronting and completely unvarnished testimony, much darker and rawer than anything I’ve come across in the world of fiction, as if no writer’s imagination could possibly capture the absolute lowest and worst aspects of humanity.
 
None of us really know how we would react in those conditions. Sometimes in dreams we may get a hint. I’ve sometimes considered dreams as experiments that our minds play on us to test our moral fortitude. I know from my father’s experiences in WW2, both in the theatre of war and as a POW, that one’s moral compass can be bent out of shape. He told me of how he once threatened to kill someone who was stealing from wounded who were under his care. The fact that the person he threatened was English and the wounded were Arabs says a lot, as my father held the same racial prejudices as most of his generation. But I suspect he’d witnessed so much unnecessary death and destruction on such a massive scale that the life of a petty, opportunistic thief seemed worthless indeed. When he returned, he had a recurring dream where there was someone outside the house and he feared to confront them. And then on one occasion he did and killed them barehanded. His telling of this tale (when I was much older, of course) reminded me of Luke Skywalker meeting and killing his Jungian shadow in The Empire Strikes Back. My father could be a fearsome presence in those early years of my life – he had demons and they affected us all.
 
Another one of my tangents, but Gaita’s ruminations on the worst of humanity perpetrated by a nation with a rich and rightly exalted history makes one realise that we should not take anything for granted. I’ve long believed that anyone can commit evil given the right circumstances. We all live under this thin veneer that only exists because we mostly have everything we need and are generally surrounded by people who have no real axe to grind and who don’t see our existence as a threat to their own wellbeing.
 
I recently saw the movie, Civil War, starring Kirsten Dunst, who plays a journalist covering a hypothetical conflict in America, consequential to an authoritarian government taking control of the White House. The aspect that I found most believable was how the rule of law no longer seemed to apply, and people had become completely tribal whereupon one’s neighbour could become one’s enemy. I’ve seen documentaries on conflicts in Rwanda and the former Yugoslavia where this has happened – neighbours become mortal enemies, virtually overnight, because they suddenly find themselves on opposite sides of a tribal divide. I found the movie quite scary because it showed what happens when the veneer of civility we take for granted is not just lifted, but disappears.
 
On the first page of his essay on Trump, Gaita sets the tone and the context that resulted in Brexit on one side of the Atlantic and Trump’s Republican nomination on the other.
 
Before Donald Trump became the Republican nominee, Brexit forced many among the left-liberal intelligentsia to ask why they had not realised that resentment, anger and even hatred could go so deep as they did in parts of the electorate.
 
I think the root cause of all these dissatisfactions and resentments that lead to political upheavals that no one sees coming is trenchant inequality. I remember my father telling me when I was a child that the conflict in Ireland wasn’t between 2 religious groups but about wealth and inequality. I suspect he was right, even though it seems equally simplistic.
 
In all these divisions that we’ve seen, including in Australia, is the perception that people living in rural areas are being left out of the political process and not getting their fair share of representation, and consequentially everything else that follows from that, which results in what might be called a falling ‘standard of living’. The fallout from the GFC, which was global, exacerbated these differences, both perceived and real, and conservative politicians took advantage. They depicted the Left as ‘elitist’, which is alluded to in the title of Gaita’s essay, and is ‘code’ for ignorant and arrogant. This happened in Australia and I suspect in other Western democracies as well, like the UK and America.
 
Gaita expresses better than most how Trump has changed politics in America, if no where else, by going outside the bounds of normal accepted behaviour for a world leader. In effect, he’s changed the social norms that one associates with a person holding that position.
 
To illustrate my point, I’ll provide selected quotes, albeit out of context.
 
To call Trump a radically unconventional politician is like calling the mafia unconventional debt collectors; it is to fail to understand how important are the conventions, often unspoken, that enables decency in politics. Trump has poured a can of excrement over those conventions.
 
He has this to say about Trump’s ‘alternative facts’ not only espoused by him, but his most loyal followers.

In linking reiterated accusations of fake news to elites, Trump and his accomplices intended to undermine the conceptual and epistemic space that makes conversations between citizens possible.
 
It is hardly possible to exaggerate the seriousness of this. The most powerful democracy on Earth, the nation that considers itself and is often considered by others to be the leader of ‘the free world’, has a president who attacks unrelentingly the conversational space that can exist only because it is based on a common understanding – the space in which citizens can confidently ask one another what facts support their opinions. If they can’t ask that of one another, if they can’t agree on when something counts as having been established as fact, then the value of democracy is diminished.
 
He then goes on to cite J.D. Vance’s (recently nominated as Trump’s running VP), Hillbilly Elegy, where ‘he tells us… that Obama is not an American, that he was “born in some far-flung corner of the world”, that he has ties to Islamic extremism…’ and much worse.
 
Regarding some of Trump’s worse excesses during his 2016 campaign like getting the crowd to shout “Lock her up!” (his political opponent at the time) Gaita makes this point:
 
At the time, a CNN reporter said that his opponents did not take him seriously, but they did take him literally, whereas his supporters took him seriously but not literally. It was repeated many times… he would be reigned in by the Republicans in the House and the Senate and by trusted institutions. [But] He hasn’t changed in office.
 
It’s worth contemplating what this means if he wins Office again in 2024. He’s made it quite clear he’s out for revenge, and he’s also now been given effective immunity from prosecution by the Supreme Court if he seeks revenge through the Justice Department while he’s in Office. There is also the infamous Project 2025 which has the totally unhidden agenda to get rid of the so-called ‘deep state’ and replace public servants with Trump acolytes, not unlike a dictatorship. Did I just use that word?
 
Trump has achieved something I’ve never witnessed before, which Gaita doesn’t mention, though I have the benefit of an additional 7 years hindsight. What I’m referring to is that Trump has created an alternative universe, and from the commentary I’ve read on forums like Quora and elsewhere, you either live in one universe or the other – it’s impossible to claim you inhabit both. In other words, Trump has created an unbridgeable divide, which can’t be reconciled politically or intellectually. In one universe, Biden stole the 2020 POTUS election from Trump, and in another universe, Trump attempted to overturn the election and failed.
 
This is the depth of division that Trump has created in his country, and you have to ask: How far will people go to defend their version of the truth?
 
It was less than a century ago that fascism threatened the entire world order and created the most extensive conflict witnessed by humankind. I don’t think it’s an exaggeration to say that we are on the potential brink of creating a new brand of authoritarianism in the country epitomised by the slogan, ‘the free world’.
