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?

REVIEW: The Leader's Bookshelf (2020)

By Thomas Scarborough


BOOK REVIEW: The Leader’s Bookshelf: 25 Great Books and Their Readers

Martin Cohen. Rowman & Littlefield, $32 (288p) ISBN 978-1-53813-576-1

The Philosopher by Marlina Vera 2018
It was Martin Cohen's sideways look at philosophy which propelled him into the limelight with Routledge's 101 Philosophy Problems (1999). In his latest book, the author would seem to recall his offbeat roots—like a band returning to its original sound.

There is an obsession in business and management circles today with leadership theory (I myself hold two Master's degrees in leadership!) and the books which propound it. There are hundreds of them, if not thousands, many of them fresh off the press. Mostly, they adhere to the ‘transformational’ model—which typically advises vision, character, and influence, and a few things besides. Such books are generally written by people who claim to have tried the formula and succeeded (many have not).


Yet, rather than read books by leaders, why not read the books the leaders read? What were their own sources of inspiration? It would seem to make eminent sense. What's more, for the doubters, Martin Cohen meticulously traces how exactly the leaders' reading is connected with their leadership: thought leaders, political leaders, corporate leaders, and leaders of many kinds. While this is not an entirely new idea,* it is still fresh, and reveals approaches to leadership which are in some way the same—only different—to those of the ‘transformational’ leadership genre.


Martin Cohen selects twenty-five ‘great books’ (by Plato, George Orwell, Herman Melville, Alex Haley, and so on) and twenty-one people who read them (Harry Kroto, Jacob Riis, Rachel Carson, Malcom X and so on), mixing them all into ten chapters.  With a potpourri like this, one is hardly going to find a systematic leadership theory. A review in Publisher’s Weekly calls the book a ‘fun yet haphazard survey’. Yet there is ‘method in the madness’. One finds it in the chapter titles. The ten chapters of the book represent an orderly progression of concepts. It seems worth listing the chapter titles here:

Meet the Wild Things (which is to say, tame the wild things of life)

Roll the Dice (which is to say, just give it a go, and see)

Save the Planet—One Page at a Time! (give a care for the wider world)

Search for Life’s Purpose

See the World in the Wider Social Context

Be Ready to Reinvent Yourself

Set Your Thinking Free

Make a Huge Profit—and Then Share It

Recognise the Power of Symbols

Follow Your Personal Legend

In each of these chapters, Martin Cohen describes the books, and describes the people who read them, then ties the two together—and like the best of biographers and historians, drops a sprinkle-sugar of fascinating facts and anecdotes into his text: for instance, John D. Rockefeller’s (miserly) penny in the Sunday School plate, a lost and lonely young Barack Obama’s attachment to a children’s book, or Richard Branson’s zany experiments with chance.


Is there any leadership theory we can glean from the book? In spite of its free-wheeling style, there surely is. All these leaders found a guiding thought which resonated with them, and they stuck to it; they often had a vision for a wider world, and its many subtleties and interconnections; they found, too, the ‘vision, character, and influence’ of the leadership books—yet so very differently. Theirs was vision which was not bound to material outcomes, character which did not always match cultural norms, and influence which seemed an after-effect rather than a carefully nurtured goal in itself.


In an important sense, one needs to note that this book is not a standard work of research—and yet it is thoughtful, balanced, and broad. It represents personal insight and wisdom, from a well informed philosopher. This is what Cohen brings to the book. In fact, the more serious leadership theory often is little more than unsupported conjecture, where the conjectural nature of it is well disguised.


There is something of an Easter egg for philosophers at the very end of the book—tucked away in the afterword. Cohen says that time and again, in the reading of successful people, ‘philosophers and philosophical works pop up as aspirational or influential texts more often than any others’. At the end of the day, it is philosophers who rule the world—by proxy as it were. And yet, what do the philosophers themselves read? In the case of Ludwig Wittgenstein anyway (one of the thought leaders described in this book) it turns out that it was a work of literary imagination, indeed humour: The Life and Opinions of Tristram Shandy, by Laurence Sterne (1759). This is one of the many surprising literary connections made by Cohen's book.



* A popular book of its kind, also The Leader's Bookshelf (without subtitle), surveys the reading of high-ranking military officers of the US Navy. Published by the Naval Institute Press (2017).

Is Popper a ‘modest’ Leo?


Posted by Martin Cohen

A few years ago, astrologer-aesthete Mark Shulgasser asked this revealing question about one of the 20th century's most under-rated philosophers for us. Popper, we should first recall, is admired for at least two big ideas: the first that science proceeds by testing hypotheses and disregarding those that fail the test (‘falsification’) and secondly, his critique of ‘historicism’ (the idea that history is marching towards a fine goal) and linked defence of liberal values and what he calls ‘the open society’. His point is that too many philosophers, from Plato down, think that they are exceptional beings - ‘philosopher kings’.

And yet... Shulgasser throws the charge back at him!

Those (like Popper) born under the astrological sign of Leo think they are kings. Do Leo philosophers think like that too?

Shulgasser continues:
‘Popper himself, so Napoleonic, the overcompensating short man. Popper's philosophical ambitions are overweening. He conquers continents. No one talks about Popper the person without noting his autocratic behavior and intransigence in contrast to his ethic of openness. Here's the Leo dilemma — the autocratic, central I versus the right of every peripheral being to claim to be the same.’
Certainly, in later years, it seems that Professor Popper lived in a house ‘supremely large in area, and adorned with numerous books, works of art, and a Steinway concert grand piano’...  But does that make him ‘Napoleonic’? Consider Brian Magee (broadcaster, politician, author, and popularizer of philosophy) on Popper. taken from Confessions of a Philosopher. Magee starts by accepting Popper as the ‘the outstanding philosopher of the twentieth century’ indeed, the “foremost philosopher of the age”! 
‘My chief impression of him at our early meetings was of an intellectual aggressiveness such as I had never encountered before [Napoleonism]. Everything we argued about he pursued relentlessly, beyond the limits of acceptable aggression in conversation. As Ernst Gombrich—his closest friend, who loved him—once put it to me, he seemed unable to accept the continued existence of different points of view, but went on and on and on about them with a kind of unforgivingness until the dissenter, so to speak, put his signature to a confession that he was wrong and Popper was right. 
In practice this meant he was trying to subjugate people. And there was something angry about the energy and intensity with which he made the attempt. This unremittingly fierce, tight focus, like a flame, put me in mind of a blowtorch, and that image remained the dominant one I had of him for many years, until he mellowed with age. . . 
He behaved as if the proper thing to do was to think one’s way carefully to a solution by the light of rational criteria and then, having come as responsibly and critically as one can to a liberal-minded view of what is right, impose it by an unremitting exercise of will, and never let up until one gets one’s way. ‘The totalitarian liberal’ was one of his nicknames at the London School of Economics, and it was a perceptive one.’
Popper it seems,  ‘turned every discussion into the verbal equivalent of a fight, and appeared to become almost uncontrollable with rage, and would tremble with anger ’.

Yet central to his philosophy is the claim that criticism does more than anything else to bring about growth and improvement of our knowledge and his political writings contain the best statement ever made of the case for freedom and tolerance in human affairs.

So who is the ‘real’ Karl Popper? Does it matter if he failed to live up to his own writings? There's a revealing story told about Popper in which he was invited to give a talk at Cambridge University ‘at the Moral Sciences Club’. 

Who did wave the poker during the acrimonious debate? I understood the Popper version of the Poker incident to put him in a meek and philosophical light and Wittgenstein in a boorish, intolerant one. Maybe I got this wrong - alas I committed myself to this in print - in my book called Philosophical Tales

Anyway, what is known is that Popper was there to present his paper entitled ‘Are There Philosophical Problems?’ at a meeting chaired by Wittgenstein. The two started arguing vehemently over whether there existed substantial problems in philosophy, or merely linguistic puzzles—the position taken by Wittgenstein. In Popper’s account, Wittgenstein gestured at him with a fireplace poker to emphasise his points. When challenged by Wittgenstein to state an example of a moral rule, Popper claims to have replied: ‘Not to threaten visiting lecturers with pokers’, after which (according to Popper) Wittgenstein threw down the poker and stormed out.

My guess it that Popper was indeed a little bit Napoleonic. Mind you, he faced a world in which he was passed over by others all the time, not least Wittgenstein, partly on some kind of unspoken notion of his not being ‘one of us’, not being quite posh enough. Popper was denied access to Oxbridge, and had to graze on the outskirts of academia as a 'not-quite-great' philosopher. 

And elsewhere Magee himself makes it clear he believes Popper is colossally underrated. Why, it’s enough to give anyone a Napoleon complex!

Why Is There Something Rather Than Nothing?

For scientists, space is not empty but full of quantum energy
Posted by Keith Tidman

Gottfried Wilhelm Leibniz introduced this inquiry more than three hundred years ago, saying, ‘The first question that should rightly be asked is, “Why is there something rather than nothing?”’ Since then, many philosophers and scientists have likewise pondered this question. Perhaps the most famous restatement of it came in 1929 when the German philosopher, Martin Heidegger, placed it at the heart of his book What Is Metaphysics?: ‘Why are there beings at all, and why not rather nothing?’

Of course, many people around the world turn to a god as a sufficient reason (explanation) for the universe’s existence. Aristotle believed, as did his forerunner Heraclitus, that the world was mutable — everything undergoing perpetual change — which he characterised as movement. He argued that there was a sequence of predecessor causes that led back deep into the past, until reaching an unmoved mover, or Prime Mover (God). An eternal, immaterial, unchanging god exists necessarily, Aristotle believed, itself independent of cause and change.

In the 13th century Saint Thomas Aquinas, a Christian friar, advanced this so-called cosmological view of universal beginnings, likewise perceiving God as the First Cause. Leibniz, in fact, was only proposing something similar, with his Contingency Argument, in the 17th century:

‘The sufficient reason [for the existence of the universe] which needs not further reason must be outside of this series of contingent things and is found in a substance which . . . is a necessary being bearing the reason for its existence within itself. . . .  This final reason for things is called God’ — Leibniz, The Principles of Nature and Grace

However, evoking God as the prime mover or first cause or noncontingent being — arbitrarily, on a priori rather than empirical grounds — does not inescapably make it so. Far from it. The common counterargument maintains that a god correspondingly raises the question that, if a god exists — has a presence — what was its cause? Assuming, that is, that any thing — ‘nothing’ being the sole exception — must have a cause. So we are still left with the question, famously posed by the theoretical physicist Stephen Hawking, ‘What is it that breathes fire into the equations and makes a universe for them to describe?’ To posit the existence of a god does not, as such, get around the ‘hard problem’: why there is a universe at all, not just why our universe is the way it is.



Some go so far as to say that nothingness is unstable, hence again impossible.


 
Science has not fared much better in this challenge. The British mathematician and philosopher Bertrand Russell ended up merely declaring in 1948, ‘I should say that the universe is just there, and that’s all’. A ‘brute fact’, as some have called it. Many scientists have embraced similar sentiments: concluding that ‘something’ was inevitable, and that ‘nothingness’ would be impossible. Some go so far as to say that nothingness is unstable, hence again impossible. But these are difficult positions to support unquestionally, given that, as with many scientific and philosophical predecessors and contemporaries, they do not adequately explain why and how. This was, for example, the outlook of Baruch Spinoza, the 17th-century Dutch philosopher who maintained that the universe (with its innumerable initial conditions and subsequent properties) had to exist. Leaping forward to the 20th century, Albert Einstein, himself an admirer of Spinoza’s philosophy, seemed to concur.

Quantum mechanics poses an interesting illustration of the science debate, informing us that empty space is not really empty — not in any absolute sense, anyway. Even what we might consider the most perfect vacuum is actually filled by churning virtual particles — quantum fluctuations — that almost instantaneously flit in and out of existence. Some theoretical physicists have suggested that this so-called ‘quantum vacuum’ is as close to nothingness as we might get. But quantum fluctuations do not equate to nothingness; they are not some modern-day-science equivalent of the non-contingent Prime Mover discussed above. Rather, no matter however flitting and insubstantial, virtual quantum particles are still something.

It is therefore reasonable to inquire into the necessary origins of these quantum fluctuations — an inquiry that requires us to return to an Aristotelian-like chain of causes upon causes, traceable back in time. The notion of a supposed quantum vacuum still doesn’t get us to what might have garnered something from nothing. Hence, the hypothesis that there has always been something — that the quantum vacuum was the universe’s nursery — peels away as an unsupportable claim. Meanwhile, other scientific hypotheses, such as string theory, bid to take the place of Prime Mover. At the heart of the theory is the hypothesis that the fundamental particles of physics are not really ‘points’ as such but rather differently vibrating energy ‘strings’ existing in many more than the familiar dimensions of space-time. Yet these strings, too, do not get us over the hump of something in place of nothing; strings are still ‘something’, whose origins (causes) would beg to be explained.

In addressing these questions, we are not talking about something emerging from nothing, as nothingness by definition would preclude the initial conditions required for the emergence of a universe. Also, ‘nothingness’ is not the mere absence (or opposite) of something; rather, it is possible to regard ‘nothingness’ as theoretically having been just as possible as ‘something’. In light of such modern-day challenges in both science and philosophy, Lugdwig Wittgenstein was at least partially right in saying, early in the 20th century (Tractatus Logico-Philosophicus, section 6.4 on what he calls ‘the mystical’), that the real mystery was, ‘Not how the world is . . . but that it is’.
