‘Brain in a Vat’: A Thought Experiment

By Keith Tidman

Let’s hypothesise that someone’s brain has been removed from the body and immersed in a vat of fluids essential for keeping the brain not only alive and healthy but functioning normally — as if it is still in a human skull sustained by other bodily organs.

A version of this thought experiment was laid out by René Descartes in 1641 in the Meditations on First Philosophy, as part of inquiring whether sensory impressions are delusions. An investigation that ultimately led to his celebrated conclusion, ‘Cogito, ergo sum’ (‘I think, therefore I am’). Fast-forward to American philosopher Gilbert Harman, who modernised the what-if experiment in 1973. Harman’s update included introducing the idea of a vat (in place of the allegorical device of information being fed to someone by an ‘evil demon’, originally conceived by Descartes) in order to acknowledge the contemporary influences of neuroscience in understanding the brain and mind.

In this thought experiment, a brain separated from its body and sustained in a vat of chemicals is assumed to possess consciousness — that is, the neuronal correlates of perception, experience, awareness, wonderment, cognition, abstraction, and higher-order thought — with its nerve endings attached by wires to a quantum computer and a sophisticated program. Scientists feed the disembodied brain with electrical signals, identical to those that people are familiar with receiving during the process of interacting through the senses with a notional external world. Hooked up in this manner, the brain (mind) in the vat therefore does not physically interact with what we otherwise perceive as a material world. Conceptualizations of a physical world — fed to the brain via computer prompts and mimicking such encounters — suffice for the awareness of experience.

The aim of this what-if experiment is to test questions not about science or even ‘Matrix’-like science fiction, but about epistemology — queries such as what do we know, how do we know it, with what certainty do we know it, and why does what we know matter? Specifically, issues to do with scepticism, truth, mind, interpretation, belief, and reality-versus-illusion — influenced by the lack of irrefutable evidence that we are not, in fact, brains in vats. We might regard these notions as solipsistic, where the mind believes nothing (no mental state) exists beyond what it alone experiences and thinks it knows.

In the brain-in-a-vat scenario, the mind cannot differentiate between experiences of things and events in the physical, external world and those virtual experiences electrically prompted by the scientists who programmed the computer. Yet, since the brain is in all ways experiencing a reality, whether or not illusionary, then even in the absence of a body the mind bears the complement of higher-order qualities required to be a person, invested with full-on human-level consciousness. To the brain suspended in a vat and to the brain housed in a skull sitting atop a body, the mental life experienced is presumed to be the same.

But my question, then, is this: Is either reality — that for which the computer provides evidence and that for which external things and events provide evidence — more convincing (more real, that is) than the other? After all, are not both experiences of, say, a blue sky with puffy clouds qualitatively and notionally the same: whereby both realities are the product of impulses, even if the sources and paths of the impulses differ?

If the experiences are qualitatively the same, the philosophical sceptic might maintain that much about the external world that we surmise is true, like the briskness of a winter morning or the aroma of fresh-baked bread, is in fact hard to nail down. The reason being that in the case of a brain in a vat, the evidence of a reality provided by scientists is assumed to resemble that provided by a material external world, yet result in a different interpretation of someone’s experiences. We might wonder how many descriptions there are of how the conceptualized world corresponds to what we ambitiously call ultimate reality.

So, for example, the sceptical hypothesis asserts that if we are unsure about not being a brain in a vat, then we cannot disregard the possibility that all our propositions (alleged knowledge) about the outside physical world would not hold up to scrutiny. This argument can be expressed by the following syllogism:

1. If I know any proposition of external things and events, then I know that I am not a brain in a vat;

2. I do not know that I am not a brain in a vat;

3. Therefore, I do not know any proposition of external things and events about the external world.

Further, given that a brain in a vat and a brain in a skull would receive identical stimuli — and that the latter are the only means either brain is able to relate to its surroundings — then neither brain can determine if it is the one bathed in a vat or the one embodied in a skull. Neither mind can be sure of the soundness of what it thinks it knows, even knowledge of a world of supposed mind-independent things and events. This is the case, even though computer-generated impulses realistically substitute for not directly interacting bodily with a material external world. So, for instance, when a brain in a vat believes that ‘wind is blowing’, there is no wind — no rushing movement of air molecules — but rather the computer-coded, mental simulation of wind. That is, replication of the qualitative state of physical reality.

I would argue that the world experienced by the brain in a vat is not fictitious or unauthentic, but rather is as real to the disembodied brain and mind as the external, physical world is to the embodied brain. Both brains fashion valid representations of truth. I therefore propose that each brain is ‘sufficient’ to qualify as a person: where, notably, the brains’ housing (vat or skull) and signal pathways (digital or sensory) do not matter.

The Philosophy of Science

The solar eclipse of May 29, 1919, forced a rethink of fundamental laws of physics

By Keith Tidman

Science aims at uncovering what is true. And it is equipped with all the tools — natural laws, methods, technologies, mathematics — that it needs to succeed. Indeed, in many ways, science works exquisitely. But does science ever actually arrive at reality? Or is science, despite its persuasiveness, paradoxically consigned to forever wending closer to its goal, yet not quite arriving — as theories are either amended to fit new findings, or they have to be replaced outright?

It is the case that science relies on observation — especially measurement. Observation confirms and grounds the validity of contending models of reality, empowering critical analysis to probe the details. The role of analysis is to scrutinise a theory’s scaffolding, to better visualise the coherent whole, broadening and deepening what is understood of the natural world. To these aims, science, at its best, has a knack for abiding by the ‘laws of parsimony’ of Occam’s razor — describing complexity as simply as possible, with the fewest suppositions to get the job done.

To be clear, other fields attempt this self-scrutiny and rigour, too, in one manner or another, as they fuel humanity’s flame of creative discovery and invention. They include history, languages, aesthetics, rhetoric, ethics, anthropology, law, religion, and of course philosophy, among others. But just as these fields are unique in their mission (oriented in the present) and their vision (oriented in the future), so is science — the latter heralding a physical world thought to be rational.

Accordingly, in science, theories should agree with evidence-informed, objective observations. Results should be replicated every time that tests and observations are run, confirming predictions. This bottom-up process is driven by what is called inductive reasoning: where a general principle — a conclusion, like an explanatory theory — is derived from multiple observations in which a pattern is discerned. An example of inductive reasoning at its best is Newton’s Third Law of Motion, which states that for every action (force) there is an equal and opposite reaction. It is a law that has worked unfailingly in uncountable instances.

But such successes do not eliminate inductive reasoning’s sliver of vulnerability. Karl Popper, the 20th-century Austrian-British philosopher of science, considered all scientific knowledge to be provisional. He illustrated his point with the example of a person who, having seen only white swans, concludes all swans are white. However, the person later discovers a black swan, an event conclusively rebutting the universality of white swans. Of course, abandoning this latter principle has little consequence. But what if an exception to Newton’s universal law governing action and reaction were to appear, instead?

Perhaps, as Popper suggests, truth, scientific and otherwise, should therefore only ever be parsed as partial or incomplete, where hypotheses offer different truth-values. Our striving for unconditional truth being a task in the making. This is of particular relevance in complex areas: like the nature of being and existence (ontology); or of universal concepts, transcendental ideas, metaphysics, and the fundamentals of what we think we know and understand (epistemology). (Areas also known to attempt to reveal the truth of unobserved things.) 

And so, Popper introduced a new test of truth: ‘falsifiability’. That is, all scientific assertions should be subjected to the test of being proven false — the opposite of seeking confirmation. Einstein, too, was more interested in whether experiments disagreed with his bold conjectures, as such experiments would render his theories invalid — rather than merely provide further evidence for them.

Nonetheless, as human nature would have it, Einstein was jubilant when his prediction that massive objects bend light was confirmed by astronomical observations of light passing close to the sun during the total solar eclipse of 1919, the observation thereby requiring revision of Newton’s formulation of the laws of gravity.

Testability is also central to another aspect of epistemology. That is, to draw a line between true science — whose predictions are subject to rigorous falsification and thus potential disproof — and pseudoscience — seen as speculative, untestable predictions relying on uncontested dogma. Pseudoscience balances precariously, depending as it does on adopters’ fickle belief-commitment rather than on rigorous tests and critical analyses.

On the plus side, if theories are not successfully falsified despite earnest efforts to do so, the claims may have a greater chance of turning out true. Well, at least until new information surfaces to force change to a model. Or, until ingenious thought experiments and insights lead to the sweeping replacement of a theory. Or, until investigation explains how to merge models formerly considered defyingly unalike, yet valid in their respective domains. An example of this last point is the case of general relativity and quantum mechanics, which have remained irreconcilable in describing reality (in matters ranging from spacetime to gravity), despite physicists’ attempts. 

As to the wholesale switching out of scientific theories, it may appear compelling to make the switch, based on accumulated new findings or the sense that the old theory has major fault lines, suggesting it has run its useful course. The 20th-century American philosopher of science, Thomas Kuhn, was influential in this regard, coining the formative expression ‘paradigm shift’. The shift occurs when a new scientific theory replaces its problem-ridden predecessor, based on a consensus among scientists that the new theory (paradigm) better describes the world, offering a ‘revolutionarily’ different understanding that requires a shift in fundamental concepts.

Among the great paradigm shifts of history are Copernicuss sun-centered (heliocentric) model of planet rotation, replacing Ptolemys Earth-centered model. Another was Charles Darwins theory of natural selection as key to the biological sciences, informing the origins and evolution of species. Additionally, Einsteins theories of relativity ushered in major changes to Newtons understanding of the physical universe. Also significant was recognition that plate tectonics explain large-scale geologic change. Significant, too, was development by Neils Bohr and others of quantum mechanics, replacing classical mechanics at microscopic scales. The story of paradigm shifts is long and continues.

Science’s progress in unveiling the universe’s mysteries entails dynamic processes: One is the enduring sustainability of theories, seemingly etched in stone, that hold up under unsparing tests of verification and falsification. Another is implementation of amendments as contrary findings chip away at the efficacy of models. But then another is the revolutionarily replacement of scientific models as legacy theories become frail and fail. Reasons for belief in the methods of positivism. 

In 1960, the physicist Eugene Wigner wrote what became a famous paper in philosophy and other circles, coining the evocative expression unreasonable effectiveness. This was in reference to the role of mathematics in the natural sciences, but he could well have been speaking of the role of science itself in acquiring understanding of the world.

Picture Post #41 The Aesthetics of Destruction

'Because things don’t appear to be the known thing; they aren’t what they seemed to be
neither will they become what they might appear to become.'


Posted by Martin Cohen


Herald Weekly image of a store in Fukushima sometime after the nuclear reactor there partially exploded. 
I think the next Picture Post should be from Ukraine, where there are so many scenes of urban destruction that are at once both tragic and appalling – yet also somehow (like this scene) somehow rather calming. These are postcards from a post-apocalyptic future, words of chaos that humanity can only briefly put off.

But about this scene, in particular, which has the quality of a paper seascape, the waves created by the numerous documents and papers thrown onto the floor. Or, writing just after Christmas, it might remind some people of the detritus left after an extravagant present–giving ceremony where the parcels and wrapping paper are all that remain. 

It is not on a huge scale, this destruction, we could imagine being tasked with cleaning it up. But it’s not the kind of mess that we come across every day either.

Determinism and Accountability

Dominos falling

By Keith Tidman

People assume that free will and moral responsibility are mutually and inextricably interwoven. That is, the default belief tends to be that people make decisions and act on them freely. On the grounds of that conviction, society condemns and punishes, or lauds and rewards, people on the basis of their actions’ supposed morality. It’s how accountability for behaviour intersects with matters like retributive and distributive justice. 


But what if decisions and actions are already decided – predetermined? Such that if an event has transpired, it is impossible it could not have happened. Might society still need to parse people’s deeds on the basis of some arbitrary construct — a community’s self-prescribed code of right and wrong — in order for society to function in an orderly fashion?


With the objective, then, of preserving social orderliness, all the while holding people responsible, doesn’t society have no option but to submit to at least the pretense of free will? Where even that pretense is itself predetermined. That is, to make-believe — for the sake of convenience, pragmatic expediency, and the evasion of disorder — that people enjoy unfettered decisions, choices, and deeds.


Okay, so far I’ve summarised what free will means by way of libertarian agency in choosing and behaving in particular ways, with the presumption, however faulty, that people could have acted otherwise. But what about its counterpoint, determinism: especially what in academic circles is often referred to as ‘hard determinism’, where determinism and freedom unreservedly conflict (called incompatibilism)?


According to determinism, for example, acting benevolently rather than selfishly (or the reverse) may be no more the exercise of unconstrained free agency than naturally having brunette hair or 20/20 vision. We may not really be ‘free’ to decide which job candidate to hire, which book to read, which model car to buy, which investment to make, which country to visit — or which political candidate to vote for.


Rather, the argument states that all decisions and deeds are predicated on the laws of nature, which inform, describe, and animate the stuff of our universe. The proposition is that people’s choices and actions are shaped (are predetermined) by all that has happened over the course of the cosmos’s entire lifespan. The basis is an unremitting regress of successive causes and outcomes recursively branching and branching in incalculable directions, nonstop. A causal determinism, sourced all the way back to the beginning of the universe.


That is, decisions and deeds inescapably result from a timeless accretion of precedents. The tumbling buildup, over far-ranging generations, of influences: like culture, genetic makeup, experiences, parenting, evolution, intelligence, identity, emotions, disposition, surroundings. As well as, every bit crucially, what naturally occurred throughout the entirety of history and prehistory.


Such factors, among others, have powerful, compelling influences, canceling out moral agency — our ability to make choices based on our sense of right and wrong. After all, in the deterministic model, the events that occurred as antecedents of current and future events did so necessarily. Indeed, we might imagine that if fissures were ever to show up in determinism’s cause-and-effect procession of happenings, the laws of nature and of human behaviour would pitch toward systemic failure — the undoing of events’ inevitability. We thus justify judging and punishing people who behave antisocially, on grounds induced by predetermination, where there is only one possible course of events.


If, however, because of the absence of free agency and volitional intent, people cannot be regarded as morally accountable, ought they be held responsible anyway, subject to legal or other kinds of sanction? To go through the motions — despite determinism dangling menacingly over systems of criminal justice everywhere. And similarly, ought people be lauded and rewarded for things deemed to have been done right? With implications for assigned guilt, sin, and evil, and other verdicts pertinent to actions freely chosen.


One answer to the two preceding questions about responsibility has been ‘yes’, on the basis of a belief system referred to as compatibilism. This asserts that free will and determinism can compatibly coexist. But this is a challenging — arguably impossible — needle to thread, short of arbitrarily warping definitions, assumptions, and preconceived conditions.


My position goes in a different, even simpler, direction from compatibilism. It is that accountability is necessitated by society having to prescribe ethical norms, no matter how contrived — and attempt to force human behaviour to fit those engineered norms — in order to avoid society alternatively sinking into chaos. In this manner, society learns, perhaps kicking and screaming, to cope with a deterministic world — a world where people cannot act otherwise than they do, and events are inevitable.


It’s difficult for us to shake intuitively favouring free will, despite its illusory naturePeople feel as if in control; they zealously covet being in control; they recoil unsettlingly at the prospect of not being in control. Fundamentally, they sense that personal agency and volitional intent define humanity. They can’t easily discard the pretense that only freely willed actions meet the criterion of warranting tribute, on the one hand, or fault, on the other. 


But even if they’re not in control, and determinism routed free will from the start, society must behave otherwise: it must hold people responsible, both to deter and punish — censure — and to reward — validate — decisions and actions as if free choice had indeed sparked them.

Aquarius Wins the World Cup - Again

By Martin Cohen

The FIFA World Cup 2022 has started and Apostagolos.com has returned to the ancient philosophical question of whether the heavens really do govern human affairs by conducting a study of the astrological profiles of the world’s top football players (tracing all the way back to the first tournament in 1930).

The results of their analysis seem to defy statistical explanation. Starting off with the remarkable fact that:
Aquarius is by far the most common star sign amongst the historical squad players - 840 past players have been an Aquarius. This curious link between the game and the sign has been noted before, with astrologers hazarding that it might be something due to the symbolism of Aquarius. Specifically, that of an individual separating from the crowd and being different, while at the same time linking to everyone on an equal, humanitarian level. Aquarian’s are supposed to produce unexpected flourishes too - the two traits seeming ideally suited to the game of football which combines teamwork with that goal-scoring moment.

• Second finding is that Pisces, with 835 players, is the second most common star sign. Astrologers, being literal folk at heart, usually predict Pisceans will seek watery sports, but there is an aspect to Pisces that makes them valuable in a soccer team, which is their selflessness. Pisceans are also creative and make strategic plays that others can convert into goals ..

Capricorn is the third most common stars sign - 769 past squad players were Capricorns, a sign associated with being good team players.

• On the other hand, Sagittarius is the least common star sign amongst the players - with ‘only’ 649 squad players to their credit. Why might that be? Maybe because traditionally the Archer loves to feel free and resist rules. Football, unique for its yellow cards and referees, ain’t their game.
What about this year’s tournament, though? Again, Aquarius is the most common star sign in 2022 - 95 squad players are an Aquarians. Pisces with 85 players is the second most common star sign but now Gemini is the third most common stars sign - 81 current players are heavenly twins. And Libra is the least common star sign amongst the players with only 53 players being a Libra from the 2022 group.

Free Will, the ‘Block Universe’, and Eternalism

In this image, the light trail left by traffic illustrates an idea central to the growing block universe theory of time, that the past, present, and future coexist.  

By Keith Tidman

The block universe is already filled with every event that ever happens. It is where what are traditionally dubbed the past, present, and future exist simultaneously, not as classically flowing linearly from one to the other. As such, these three distinct aspects to time, which by definition exclude the notion of tense, are equally real. None is in any way advantaged over the others.

The orthodox model of a ‘block universe’ describes a four-dimensional universe, resembling a cube, which merges the three dimensions of space and one of time, along the lines that Albert Einstein theorised in his special relativity.

Might this tell us something about the possibility of free will in such a universe? Before we try to answer, let’s explore more particulars about the block universe itself.


If observed from outside, the block would appear to hold all of space and time. The spacetime coordinates of someone’s birth and death — and every occurrence bracketed in between — accordingly exist concurrently somewhere within the block. The occurrences are inalterably and forever in the block. This portrayal of foreverness is sometimes referred to as ‘eternalism’, defined as a complete history of all possible events.


Conventionally, the block is considered static. But maybe it’s not. What if, for example, what we ordinarily call ‘time’ is better called change? After all, the second law of thermodynamics tells us that the state of entropy of the entire universe — meaning the presence of disorder — will always result in a net increase. It never decreases. Until, that is, the universe ultimately ends. Demonstrating how change, as in the case of entropy, moves inexorably in one direction. The inevitability of such change has a special place for humankind, as reality transforms.


Entropy is thus consummate change, on a cosmic scale, which is how the illusion of something we call ‘the arrow of time’ manifests itself in our conscious minds. As such, change, not time, is what is truly fundamental in nature. Change defines our world. Which, in turn, means that what the block universe comprises is necessarily dynamical and fluid, rather than frozen and still. By extension, the block universe challenges the concept of eternalism.


This also means that cause and effect exist (as do correlation and effect) as fundamental features of a universe in which ‘becoming’, in the form of change, is rooted. Despite past, present, and future coexisting within the block universe, causes still necessarily precede and can never follow the effects of what appears as relentless change. Such change serves, in place of illusory time, as one axis matched up with three-dimensional space. The traditional picture of the block universe comprising nondynamical events would contradict the role of cause in making things happen.


So, let’s return to the issue of free will within the block universe.


First off, the block universe has typically been described as deterministic. That is, if every event within the universe happens simultaneously according to the precise space and time coordinates the model calls for, then everything has been inescapably preordained, or predetermined. It all just is. Free will in such a situation becomes every bit as much an illusion as time.


But there’s a caveat pushing back against that last point. In the absence of freewill, humans would resemble automatons. We would be contraption-like assemblages of parts that move but lack agency, and would be devoid of meaningful identity and true humanity. We, and events, could be seen as two-dimensional set pieces on a stage, deterministically scripted. With no stage direction or audience — and worse, no meaning. Some might proclaim that our sense of autonomy is yet another illusion, along with time. But I believe, given our species’ active role within this dynamical cosmos, that reality is otherwise.


Further, determinism would take us off the hook of accountability and consequences. Fate, bubbling up from the capriciousness of nature’s supposed mechanistic forces, would situate us in a world stripped of responsibility. A world in which our lives are pointlessly set to automatic. Where the distinction between good and evil becomes fuzzy. In this world, ethical norms are arbitrary and fickle — a mere stage prop, giving the appearance of consequences to actions.


And yet, the blueprint above replacing the concept of time with that of change puts free will back into play, allowing a universe in which our conscious minds freely make decisions and behave accordingly. Or, at least, seemingly so. In particular, for there to be events at the space-change coordinates of the block universe, there must be something capable of driving (causing) change. The events aren’t simply fated. That ‘something’ can only be choice associated with truly libertarian free will.


There’s one other aspect to free will that should be mentioned. Given that motion within the three-dimensional space of the block universe can occur, not only the what but also the where of events can be changed. Again, agency is required to freely choose. It’s like shuffling cards: the cards remain the same, but their ‘coordinates’ (location) change.


In refutation of determinism, the nature of change as described above allows that what decisions we make and actions we take within the block universe are expressions of libertarian free will. Our choices become new threads woven through the block universe’s fabric — threads that prove dissoluble, however, through the ceaselessness of change.

Beetle in a Box: A Thought Experiment

By Keith Tidman

Let’s hypothesise that everyone in a community has a box containing a ‘beetle’. Each person can peer into only his or her box, and never into anyone else’s. Each person insists, upon looking into their own box, that they know what a ‘beetle’ is.

But there’s a catch: Each box might contain something different from some or all the others; each box might contain something that continually changes; or each box might actually contain nothing at all. Yet upon being asked, each person resolutely continues to use the word ‘beetle’ to describe what’s in their box. Refusing, even if probed, to more fully describe what they see, even if not showing it. The word ‘beetle’ thus simply meaning ‘that thing inside a person’s box’.

So, what does the thought experiment, set out by the influential twentieth-century philosopher Ludwig Wittgenstein in his book Philosophical Investigations,  tell us about language, mind, and reality?

As part of this experiment, Wittgenstein introduced the concept of a ‘private language’. That is, a language with a vocabulary and structure that only its originator and sole user understands, all the while untranslatable and obscure to everyone else. The original notion of a private (personal) language was in being analogous to what a person might use in attempting to convey his or her unique experiences, perceptions, and senses — the person’s individualised mental state. However, one criticism of such a personal language, by reason of being mostly unfathomable to others, is in its not holding to the definitional purpose of a working language as we commonly know it: to communicate with others, using mutually agreed-upon and comprehended guidelines.

Notably, however, the idea of a ‘private language’ has been subject to different interpretations over the years — besides in expressing to others one’s own mental state — on account of what some people have held are its inherent ambiguities. Even on its surface, such a private language does seem handicapped, inadequate for faithfully representing external reality among multiple users. A language unable to tie external reality to ‘internal’ reality — to a person’s ‘immediate private sensations’, as Wittgenstein put it, such as pain the individual feels. That is, to the user’s subjective, qualitative state of mind. Yet, the idea that people’s frames of mind, subjective experiences, and sense of awareness are unknowable by others, or at least uncertainly known, seems to come to us quite naturally.

Conventionally speaking, we become familiar with what something is because of its intrinsic physical characteristics. That ‘something’ has an external, material reality, comfortably and knowingly acknowledged by others in abidance to norms within the community. The something holds to the familiar terms of the ‘public language’ we use to describe it. It conveys knowledge. It denotes the world as we know it, precipitated by the habitual awareness of things and events. There’s a reassuringly objective concreteness to it.

So, if you were to describe to someone else some of the conventional features of, say, a sheet of paper or of an airplane or of a dog, we would imagine that other people could fathom, with minimal cognitive effort and without bewilderment, what the item you were describing was. A ‘private language’ can’t do any of that, its denying us a universally agreed-upon understanding of what Wittgenstein’s beetle-in-the-box might actually be. To the point about effectiveness, a ‘private language’ — where definitions of terms may be adversely arbitrary, unorthodox, imprecise, and unfamiliar  differs greatly from a ‘public language’ — where definitions of terms and syntactical form stick to conventional doctrine.

Meanwhile, such a realisation about the shortcomings of a ‘private language’ points to an analogy applicable to a ‘shared’ (or public) language: What happens in the case of expressing one’s personal, private experiences? Is it even possible to do so in an intelligible fashion? The discussion now pivots to the realm of the mind, interrogating aspects such as perception, appearance, attention, awareness, understanding, belief, and knowledge.

For example, if someone is in pain, or feeling joy, fear, or boredom, what’s actually conveyed and understood in trying to project their situation to other people? It’s likely that only they can understand their own mental state: their pain, joy, fear, or boredom. And any person with whom they are speaking, while perhaps genuinely empathetic and commiserative, in reality can only infer the other individual’s pain while understanding only their own.

Put another way, neither person can look into the other’s ‘box’; neither can reach into the other’s mind and hope to know. There are epistemic (knowledge-related) limits to how familiar we can be with another person’s subjective experience, even to the extent of the experience’s validation. Pain, joy, fear, and boredom are inexpressible and incomprehensible, beyond rough generalizations and approximations, whether resorting to either a ‘private’ or public language.

What’s important is that subjective feelings obscurely lack form — like the mysterious ‘beetle’. They lack the concrete, external reality mentioned previously. The reason being that your feelings and those of the other person are individualised, qualitative, and subjective. They are what philosophy of mind calls qualia. Such that your worry, pleasure, pride, and anxiety likely don’t squarely align with mine or the next person’s. Defaulting, as Wittgenstein put it, to a ‘language game’ with consequences, with its own puzzling syntactical rules and lexicon. And as such, the game’s challenge to translate reality into precise, logical, decipherable meaning.

All of which echoes Wittgenstein’s counsel against the inchoate, rudimentary notion of a ‘private language’, precisely because of its lacking necessary social, cultural, historical, and semiotic context. A social backdrop whereby a language must be predictably translatable into coherent concepts (with the notable exception of qualia). Such as giving things identifiable, inherent form readily perceived by others, according to the norms of social engagement and shared discourse among people within a community.

Shape-shifting ‘beetles’ are a convenient analogue of shape-shifting mental states. Reflecting altering ways our qualitative, subjective states of mind influence our choices and behaviours, through which other people develop some sense of our states of mind and how others may define us  a process that, because  of its mercurial nature, is seldom reliable. The limitations discussed here of Wittgenstein’s ‘private language’ arguably render such a medium of communication unhelpful to this process.

We make assumptions, based on looking in the box at our metaphorical beetle (the thing or idea or sensation inside), that will uncover a link: a connection between internal, subjective reality — like the pain that Wittgenstein’s theorising demonstrably focused on, but also happiness, surprise, sadness, enthrallment, envy, boredom — and external, objective reality. However, the dynamics of linguistically expressing qualitative, individualised mental states like pain need to be better understood.

So, what truths about others states of mind are closed off from us, because we’re restricted to looking at only our own ‘beetle’ (experience, perception, sensation)? And because we have to reconcile ourselves to trying to bridge gaps in our knowledge by imperfectly divining, based on externalities like behaviour and language, what’s inside the boxes’ (minds) of everyone else?

Science and Humanity

by Allister John Marran

NASA's Double Asteroid Redirection Test, 26 September 2022

We have officially transitioned backwards as a species into an era of personal belief over facts, of emotion over intellect, of blind trust over earned authority.

We have striven to become significantly more fallible by sitting at the camp fire exchanging stories, choosing to first believe and then explore, a honeycomb of fictional realities.

Our little rock doesn't stand still. It moves at thousands of kilometres an hour around the sun, while rotating constantly on its own axis, with gravity pulling eternally—and yet some very clever people place explosives in a cylinder and fire it upwards, breaking free of our planet and then moving at thirty times the speed of sound to another celestial body which is also rotating around the sun on its own axis.

They aim the rocket at an empty point in space, knowing that the other planet will arrive at the exact moment the rocket does.

We can do all of that, and do it safely and reliably, not because of faith or emotion, not because of belief or trust. The numbers tell them it will be there, every time, to the second.

Science and mathematics do not care about your feelings or your complex personal belief structures. They do not worry about offending people or massaging ones’ scruples. It simply and succinctly solves a physical or theoretical problem as efficiently as possible.

Mathematics is the universal language. Unchanging and uncompromised.

But emotion and belief and trust are the language of mankind, it's what makes us human, a most endearing quality that allows love and hate, care and neglect, laughter and crying, and great triumph and cruelty.

The great works of Shakespeare and Tolkien and King and Koontz could simply not be written in the language of maths. They require a suspension of disbelief and an emotional core.

Because human behaviour hardly ever adds up.

But our strength is our weakness, and it's the exploitation of these analogue traits which has led us to place a greater importance on our beliefs than the facts.

More than ever, nefarious actors are taking the political, religious or social stage, and asking you to forget the truth, ignore the facts, trample the math, destroy the science and just believe them.

Trust them implicitly. Don't over-think, don't look too deeply, don't add it up or use common sense to interrogate the facts. Just trust them.

And so we now live in an age where conspiracy theoriests can mobilise an army, televangelists can ask their congregation for another eight hundred million to buy another jet, politicians can command more loyalty the more they lie and cheat and thieve, and Finding Bigfoot can enter a twelfth season without ever finding Bigfoot.

It's not necessary to destroy your humanity in order to defeat these exploitative forces trying to cajole you into believing nonsense. You don't have to stop your suspension of disbelief, or temper your emotion, or stop loving the ones you love.

You just need to compartmentalise or segment various types of knowledge and activity, and treat each one a little differently.

When you read Shakespeare or watch a romantic comedy or praise your God or watch your football team, let it all out, go to town, laugh and weep and give it your best.

But don't ever give a person the keys to your soul or your belief structure. Don't allow a politician to get you worked up. Don't let your guard down when you need to keep your wits.

Know when to use the language of people or the language of maths and science. Become fully bilingual and know when to change between the two.

I Stand in the Middle of the Ocean

by Tioti Timon *

In the middle of the ocean I stand
without anyone to help.
Days, months, and years have left me behind.
I search for my home,
I call you by name – Kiribati, Where are you?
Hear the voice of my song.
Rise up, rise up, you the centre of the world.
Arise from the depth of the Ocean
So you may be seen from afar
Be lifted higher, and higher
With no friends to help me
They left me days and years ago

—Tom Toakai

In the middle of the ocean means ‘the deep sea’ or ‘deep void’ where feet cannot stand. Standing in the middle of the deep sea means living without a grounding, or strong foundation to stand on. The tone of this song harks back to the 1960s, when Kiribati was still under the British Empire. With a limitation of natural resources, Kiribati relied on the phosphate island of Banaba as the only resource for its economic development.

However, the phosphate was mined by the British, and when it was exhausted, they granted us independence, and left us with a legacy that ignored economic development.** The impact of climate change reflects the continuous roughshod treatment of poor and small island nations like Kiribati, by the powerful nations of the developed world. We have been ignored, and now we are paying the cost of what rich countries are doing for their own benefit, development, and security.

The second line, ‘I stand without anyone to help, days and years’ expresses the complaint of the people of Kiribati, after being used, and then left to stand on their own without a single viable industry on the islands. Being left by the British with limited resources has given the people of Kiribati a hard time to develop their country. Even though Kiribati is poor, and constantly oppressed and victimised by the impacts of climate change, the song encourages the people to fight for their land, their rights and their freedoms.

The Kiribati phrase, ‘Ko mena ia?’ literally means ‘Kiribati, where are you?’ In this song, the composer reminds his people to call out the name of their country, which seems to be lost in the middle of the Pacific Ocean, after being left helpless by the British, and at the same time destroyed by the ignorance of rich countries. The composer suggests that calling out the name of a country is a source of strength, to enable its inhabitants to stand up for their country.

Even though Kiribati was left with very little, we should own the name of our country, and not accept that the situation is lost and hopeless, because we have our islands, and we also have our ocean—our home and refuge, our well-being and our future. We should not remain silent, but must keep on calling the name of our islands to rise from beneath the ocean. This means that we must not rely on other sources to build our lives, but rather to build with our own lands, culture, and ways of living. As islanders, we must return to our home, the home of our ancestors, our cultural ways of living, built by our own ancestral wisdom and knowledge, and not by foreigners.

‘Rise up from the ocean,’ serves to remind the people to rise and stand on their own feet, utilising their own knowledge and skills to bring out what is there in their ocean. It is a wake-up call to the new generation who are caught up with the influences of a new civilisation that replaces traditional ways of living.

‘Arise, arise from the bottom of the ocean, so that you will be seen by those from afar’ is thus a challenge for the islands to rise up, not only to cry out for help, but to do something about it for themselves. It is a call for action by the islanders themselves, to rise up as lights to the world, to tell the world that ‘We are the sea, we are the ocean, we must wake up to this ancient truth and together use it.’

We have a freedom which must not be allowed to be taken away again. We must not allow others to determine our own future, but rather create a future that matches our own plans and dreams. We need to learn from our experiences, the impact of globalisation and climate change ‘to cherish our identities and rediscover ourselves as guardians of the best for the next generations’.***

Slums fill Bangalore city. Most of the people staying in them are construction workers who set up temporary abodes near the construction area. Sometimes you will see the slum dwellers going on with their regular activities out on the road. What option do they have?

The scene seems so complete and wholesome with the little girl child happily enjoying her play time in the toy car while watching her mother cook. But if I would have to cook on the street on a temporary earthen chulha every day, I would pull my hair out. Or would I?

Where Do Ideas Come From?

By Keith Tidman

Just as cosmic clouds of dust and gas, spanning many light-years, serve as ‘nurseries’ of new stars, could it be that the human mind similarly serves as a nursery, where untold thought fragments coalesce into full-fledged ideas?

At its best, this metaphor for bringing to bear creative ideas would provide us with a different way of looking at some of the most remarkable human achievements in the course of history.

These are things like Michelangelo’s inspired painting, sculpting, architecture, and engineering. The paradigm-shifting science of Niels Bohr and Max Planck developing quantum theory. The remarkable compositions of Mozart. The eternal triumvirate of Socrates, Plato, and Aristotle — whose intellectual hold remains to today. The piercing insights into human nature memorably expressed by Shakespeare. The democratic spread of knowledge achieved through Gutenberg’s printing press. And so many more, of course.

To borrow from Newton (with his nod to the generations of luminaries who set the stage for his own influences upon science and mathematics), might humbler souls, too, learn to ‘stand on the shoulders of such giants’, even if in less remarkable ways? Yet still to reach beyond the rote? And, if so, how might that work?

I would say that, for a start, it is essential for the mind to be unconstrained by conformance and orthodox groupthink in viewing and reconceiving the world: a quest for patterns. The creative process must not be sapped by concern over not getting endeavours right the first or second or third time. Doubting ideas, putting them to the test through decomposition and recomposition, adds to the rigour of those that optimally survive exploitation and scrutiny.

To find solutions that move significantly beyond the prevailing norms requires the mind to be undaunted, undistracted, and unflagging. Sometimes, how the creative process starts out — the initial conditions, as well as the increasing numbers of branching paths along which those conditions travel — greatly shapes eventual outcomes; other times, not. All part of the interlacing of analysis and serendipitous discovery. I think that tracing the genealogy of how ideas coalesce informs that process.

For a start, there’s a materialistic aspect to innovative thought, where the mind is demystified from some unmeasurable, ethereal other. That is, ideas are the product of neuronal activity in the fine-grained circuity of the brain, where hundreds of trillions of synapses, acting like switches and routers and storage devices, sort out and connect thoughts and deliver clever solutions. Vastly more synapses, one might note, than there are stars in our Milky Way galaxy!

The whispering unconscious mind, present in reposed moments such as twilight or midnight or simply gazing into the distance, associated with ‘alpha brain waves’, is often where creative, innovative insights dwell, being readied to emerge. It’s where the critical mass of creative insights is housed, rising to challenge rigid intellectual canon. This activity finds a force magnifier in the ‘parallel processing’ of others’ minds during the frothy back and forth of collaborative dialogue.

The panoply of surrounding influences helps the mind set up stencils for transitioning inspiration into mature ideas. These influences may germinate from individuals in one’s own creative orbit, or as inspiration derived from the culture and community of which one is a part. Yet, synthesising creative ideas across fields, resulting in multidisciplinary teams whose members complement one another, works effectively to kindle fresh insights and solutions.

Thoughts may be collaboratively exchanged within and among teams, pushing boundaries and inciting vision and understanding. It’s incremental, with ideas stepwise building on ideas in the manner famously acknowledged by Newton. Ultimately, at its best the process leads to the diffusion of ideas, across communities, as grist for others engaged in reflection and the generation of new takes on things. Chance happenings and spontaneous hunches matter, too, with blanks cooperatively filled in with others’ intuitions.

As an example, consider that, in a 1959 talk, the Nobel prize winning physicist, Richard Feynman, challenged the world to shrink text to such an extent that the entire twenty-four-volume Encyclopedia Britannica could fit onto the head of a pin. (A challenge perhaps reminiscent of the whimsical question about ‘the number of angels fitting on the head of a pin’, at the time intended to mock medieval scholasticism.) Meanwhile, Feynman believed there was no reason technology couldn’t be developed to accomplish the task. The challenge was met, through the scaling of nanotechnology, two and a half decades later. Never say never, when it comes to laying down novel intellectual markers.

I suggest that the most-fundamental dimension to the origination of such mind-stretching ideas as Feynman’s is curiosity — to wonder at the world as it has been, as it is now, and crucially as it might become. To doggedly stay on the trail of discovery through such measures as what-if deconstruction, reimagination, and reassembly. To ferret out what stands apart from the banal. And to create ways to ensure the right-fitting application of such reinvention.

Related is a knack for spotting otherwise secreted links between outwardly dissimilar and disconnected things and circumstances. Such links become apparent as a result of combining attentiveness, openness, resourcefulness, and imagination. A sense that there might be more to what’s locked in one’s gaze than what immediately springs to mind. Where, frankly, the trite expression ‘thinking outside-the-box’ is itself an ironic example of ‘thinking inside-the-box’.

Forging creative results from the junction of farsightedness and ingenuity is hard — to get from the ordinary to the extraordinary is a difficult, craggy path. Expertise and extensive knowledge is the metaphorical cosmic dust required in order to coalesce into the imaginatively original ideas sought.

Case in point is the technically grounded Edison, blessed with vision and critical-thinking competencies, experiencing a prolific string of inventive, life-changing eureka moments. Another example is Darwin, prepared to arrive at his long-marinating epiphany into the brave world of ‘natural selection’. Such incubation of ideas, venturing into uncharted waters, has proven immensely fruitful.

Thus, the ‘nurseries’ of thought fragments, coalescing into complex ideas, can provide insight into reality — and grist for future visionaries.

Neo-Medievalism and the New Latin

By Emile Wolfaardt

Medieval Latin (or Ecclesiastical Latin, as it is sometimes called), was the primary language of the church in Europe during the Dark Ages. The Bible and its laws and commands were all in Latin, as were the punishments to be meted out for those who breached its dictates. This left interpretation and application up to the proclivities of the clergy. Because the populace could not understand Latin, there was no accountability for those who wielded the Latin sword.

We may have outgrown the too-simplistic ideas of infanticidal nuns and the horror stories of medieval torture devices (for the most part, anyway). Yet the tragedy of the self-serving ecclesiastical economies, the gorgonising abuse of spiritual authority, the opprobrious intrusion of privacy, and disenfranchisement of the masses still cast a dark shadow of systemic exploitation and widespread corruption over that period. The few who birthed into the ranks of the bourgeois ruled with deleterious absolutism and no accountability. The middle class was all but absent, and the subjugated masses lived in abject poverty without regard or recourse. There was no pathway to restation themselves in life. It was effectively a two-class social stratification system that enslaved by keeping people economically disenfranchised and functionally dependent. Their beliefs were defined, their behavior was regulated, and their liberties were determined by those whose best interest was to keep them stationed where they were.

It is the position of this writer that there are some alarming perspectives and dangerous parallels to that abuse in our day and age that we need to be aware of.

There has been a gargantuan shift in the techno-world that is obfuscatious and ubiquitous. With the ushering in of the digital age, marketers realised that the more information they could glean from our choices and conduct, the better they could influence our thinking. They started analysing our purchasing history, listening to our conversations, tracking key words, identifying our interests. They learned that people who say or text the word ‘camping’ may be in the market for a tent, and that people who buy rifles, are part of a shooting club, and live in a particular area are more likely to affiliate with a certain party. They learned that there was no such thing as excess data – that all data is useful and could be manipulated for financial gain.

Where we find ourselves today is that the marketing world has ushered in a new economic model that sees human experiences as free raw material to be taken, manipulated, and traded at will, with or without the consent of the individual. Google's vision statement for 2022 is ‘to provide access to the world's information in one click’. Everything, from your heart rate read by your watch, your texts surveyed by your phone’s software, your words recorded by the myriad listening devices around you, your location identified by twenty apps on your phone, your GPS, your doorbell, and the security cameras around your home are garnering your data. And we even pay for these things. It is easier to find a route using a GPS than a map, and the convenience of a smart technology seems, at first glance anyway, like a reasonable exchange.

Our data is being harvested systematically, and sold for profit without our consent or remuneration. Our search history, buying practices, biometric data, contacts, location, sleeping habits, exercise routine, self-discipline, articles we pause our scrolling to peruse, even whether we use exclamation marks in our texts – the list continues almost endlessly – and a trillion other bits of data each day is recorded. Then it is analysed for behavioural patterns, organised to manipulate our choices, and sold to assist advertisers to prise the hard-earned dollars out of our hands. It is written in a language very few people can understand, imposed upon us without our understanding, and used for financial gain by those who do not have our best interest at heart. Our personal and private data is the traded for profit without our knowledge, consent, or benefit.

A new form of economic oppression has emerged, ruthlessly designed, implemented by the digital bourgeois, and built exclusively on harvesting our personal and private data – and we gladly exchanged it for the conveniences it offered. As a society, we have been gaslighted into accepting this new norm. We are fed the information they choose to feed us, are subject to their manipulation, and we are simply fodder for their profit machine. We are indeed in the oppressive age of Neo-Medievalism, and computer code is the new Latin.

It seems to have happened so quickly, permeated our lives so completely, and that without our knowledge or consent.

But it is not hopeless. As oppressive as the Dark Ages were, that period came to an end. Why? Because there were people who saw what was happening, vocalised and organised themselves around a healthier social model, and educated themselves around human rights, oppression, and accountable leadership. After all – look at us now. We were birthed out of that period by those who ushered in the Enlightenment and ultimately Modernity.

Reformation starts with being aware, with educating oneself, with speaking up, and with joining our voices with others. There is huge value to this digital age we have wholeheartedly embraced. However, instead of allowing it to oppress us, we must take back control of our data where we can. We must do what we need to, to maximise the opportunities it provides, join with those who see it for what it is, help others to retain their freedom, and be a part of the wave of people and organisations looking for integrity, openness, and redefinition in the process. The digital age with its AI potential is here to stay. This is good. Let’s be a part of building a system that serves the needs of the many, that benefits humanity as a whole, and that lifts us all to a better place.

The Uncaused Multiverse: And What It Signifies

By Keith Tidman

Here’s an argument that seems like commonsense: everything that exists has a cause; the universe exists; and so, therefore, the universe has a cause. A related argument goes on to say that the events that led to the universe must themselves ultimately originate from an uncaused event, bringing the regress of causes to a halt.

But is such a model of cosmic creation right?

Cosmologists assert that our universe was created by the Big Bang, an origin story developed by the Belgian physicist and Catholic priest Georges Lemaitre in 1931. However, we ought not to confuse the so-called singularity — a tiny point of infinite density — and the follow-on Big Bang event with creation or causation per se, as if those events preceded the universe. Rather, they were early components of a universe that by then already existed, though in its infancy.

It’s often considered problematic to ask ‘what came before the Big Bang’, given the event is said to have led to the creation of space and time (I address ‘time’ in some detail below). By extension, the notion of nothingness prior to the Big Bang is equally problematic, because, correctly defined, nothingness is the total, absolute absence of everything — even energy and space. Although cosmologists claim that quantum fluctuations, or short bursts of energy in space, allowed the Big Bang to happen, we are surely then obliged to ask what allowed those fluctuations to happen.

Yet, it’s generally agreed you can’t get something from nothing. Which makes it all the more meaningful that by nothingness, we are not talking about space that happens to be empty, but rather the absence of space itself.

I therefore propose, instead, that there has always been something, an infinity where something is the default condition, corresponding to the impossibility of nothingness. Further, nothingness is inconceivable, in that we are incapable of visualising nothingness. As soon as we attempt to imagine nothingness, our minds — the act of thinking about it — causes the otherwise abstraction of ‘nothingness’ to turn into the concreteness of ‘something’: a thing with features. We can’t resist that outcome, for we have no basis in reality and in experience that we can match up with this absolute absence of everything, including space, no matter how hard we try to picture it in our mind’s eye.

The notion of infinity in this model of being excludes not just a ‘first universe’, but likewise excludes a ‘first cause’ or ‘prime mover’. By its very definition, infinity has no starting point: no point of origin; no uncaused cause. That’s key; nothing and no one turned on some metaphorical switch, to get the ball rolling.

What I wish to convey is a model of multiple universes existing — each living and dying — within an infinitely bigger whole, where infinity excludes a ‘first cause’ or ‘first universe’.

In this scenario, where something has always prevailed over nothingness, the topic of time inevitably raises its head, needing to be addressed. We cannot ignore it. But, I suggest, time appears problematic only because it's misconceived. Rather, time is not something that suddenly lurches out of the starting gate upon the occurrence of a Big Bang, in the manner that cosmologists and philosophers have typically described how it happens. Instead, when properly understood, time is best reflected in the unfolding of change.

The so-called ‘arrow of time’ traditionally appears to us in the three-way guise of the past leading to (causing) the present leading to the future. Allegorically, like a river. However, I propose that past and future are artificial constructs of the mind that simply give us a handy mechanism by which to live with the consequences of what we customarily call time: by that, meaning the consequences of change, and thus of causation. Accordingly, it is change through which time (temporal duration) is made visible to us; that is, the neurophysiological perception of change in human consciousness.

As such, only the present — a single, seamless ‘now’ — exists in context of our experience. To be sure, future and past give us a practical mental framework for modeling a world in ways that conveniently help us to make sense of it on an everyday level. Such as for hypothesising about what might be ahead and chronicling events for possible retrieval in the ‘now’. However, future and past are figments, of which we have to make the best. ‘Time reflected as change’ fits the cosmological model described here.

A process called ‘entropy’ lets us look at this time-as-change model on a cosmic scale. How? Well, entropy is the irresistible increase in net disorder — that is, evolving change — in a single universe. Despite spotty semblances of increased order in a universe — from the formation of new stars and galaxies to someone baking an apple pie — such localised instances of increased order are more than offset by the governing physical laws of thermodynamics.

These physical laws result in increasing net disorder, randomness, and uncertainty during the life cycle of a universe. That is, the arrow of change playing out as universes live and peter out because of heat death — or as a result of universes reversing their expansion and unwinding, erasing everything, only to rebound. Entropy, then, is really super-charged change running its course within each universe, giving us the impression of something we dub time.

I propose that in this cosmological model, the universe we inhabit is no more unique and alone than our solar system or beyond it our spiral galaxy, the Milky Way. The multiplicity of such things that we observe and readily accept within our universe arguably mirrors a similar multiplicity beyond our universe. These multiple universes may be regarded as occurring both in succession and in parallel, entailing variants of Big Bangs and entropy-driven ‘heat deaths’, within an infinitely larger whole of which they are a part.

In this multiverse reality of cosmic roiling, the likelihood of dissimilar natural laws from one universe to another, across the infinite many, matters as to each world’s developmental direction. For example, in both the science and philosophy of cosmology, the so-called ‘fine-tuning principle’ — known, too, as the anthropic principle — argues that with enough different universes, there’s a high probability some worlds will have natural laws and physical constants allowing for the kick-start and evolution of complex intelligent forms of life.

There’s one last consequence of the infinite, uncaused multiverse described here. Which is the absence of intent, and thus absence of intelligent design, when it comes to the physical laws and materialisation of sophisticated, conscious species pondering their home worlds. I propose that the fine-tuning of constants within these worlds does not undo the incidental nature of such reality.

The special appeal of this kind of multiverse is that it alone allows for the entirety of what can exist.
