Models, Metaphysics and Reality: How Philosophy keeps science on track


By Rob Hamilton

Does God exist? What is consciousness? How can we know what is real?

Questions such as these have always perplexed humanity and despite the great advances made over recent centuries in understanding the behaviour of the world around us, we seem to be no closer to answering these core questions about the nature of existence.

In my new book Anything Goes – A Philosophical Approach to Answering the God Question, I argue that, paradoxically, answers to these questions can be obtained – but only once we recognise that no knowledge of the true structure of reality is possible. What do I mean by this? Well, essentially that claims about the structure of reality are models that describe the way our experience of how the world behaves. It is these models that then become our reality.

Put short, all the world is models

The popular notion of how science progresses is that we are steadily, if slowly, getting closer to the truth about the nature of the world around us. Indubitably, as time has gone on, scientific advances have been made and, yes, we have reached the stage where two great theories, Einstein’s General Relativity and the Standard Model of particle physics, provide us with a nearly complete description of the universe. We just need some clever physicists to iron out a few wrinkles like dark matter and dark energy in a Theory of Everything, and then we will have arrived at the Truth of how reality is structured.

The naivety of this belief is striking, a point highlighted by 20th century philosopher of science, Karl Popper, when he pointed out that scientific theories can never be proven to be true. Rather, they are working assumptions about the way the world is, that are supported by the evidence. Until they aren’t. 

Take Newton’s theory of gravity: this was thought to be true until anomalies like the precession of the perihelion of the planet Mercury were discovered. Nowadays, it is Einstein’s theory that provides the correct answer. But this raises the possibility that if we manage to come up with a Theory of Everything, who is to say that one day we will not conduct an experiment or make an observation that contradicts this theory too? For this reason, even if physicists were to discover the true structure of reality, they could never know it! 

“Okay”, some might say. “Although we can never know that we have reached the truth, at least we can say that our current theories are ‘more true’ than the previous ones”. This view is known as Convergent Realism and was powerfully critiqued in a 1981 paper by the philosopher Larry Laudan. 

At the everyday level, Einstein’s theory actually provides only very slightly different results to Newton’s, but the way it characterises the universe is completely different. Newton’s theory is set in the common-sense world of three-dimensional space plus a separate conception of time. Einstein’s is based on the notion of curved four-dimensional spacetime. Who can say what the universe will look like according to the next theory? As Schrödinger quipped, quantum mechanics tells us that cats can be alive and dead at the same time and that the building blocks of our universe can be both waves and particles. Weird, yes, but might it be that the true nature of the universe is just as weird and perhaps even beyond our ability to comprehend? 

Ultimately, scientific theories are models of the way the universe works. They allow us to understand the universe in terms of its behaviour, and we can use them to predict how the macroscopic objects of our experience, such as tables, stars and light bulbs behave. They do this by characterising the universe in a certain way that helps us get to grips with it. Because, as humans, we just do not have the tools to find out what the universe is ‘really like’.

The Map is the territory

Now comes the plot twist. The surprising but unavoidable consequence of this conceptual speed limit, is that the structure or make-up of this reality that we are modelling is irrelevant! It is only reality’s behaviour that matters. It is reality’s behaviour that we are modelling and a good model will predict its behaviour well. But if reality’s structure is unknowable and elusive, then it will forever remain a shadowy mysterious thing lying behind the veil. It is only the structure and objects of our models that can be known to us. These are the things that we live by and that give our lives meaning. And so these are the only objects that can be considered ‘real’ in any meaningful sense – if the objects of our models are not real, then nothing is real.

And so, what we have here, I would argue, is a case of The Emperor’s New Clothes. Many scientists and physicists are aware that all of our understanding is in terms of our models, but avoid engaging with the implications of this, because it is unnecessary for day to day work and raises difficult questions. They cling to the idea that there must be a ‘right answer’ out there, because if there isn’t, then well doesn’t everything fall apart? Where are the standards of correctness? What is to stop us from just claiming that whatever we like is true? In my book, I argue that these worries are unfounded. Although the structure of reality is unknowable, the good news is that it does behave in a certain way. And so not all models are created equal.

Anything Goes

I like to call this way of thinking the ‘Anything Goes’ method, because with no knowable reality to assess our models against, the only standard of correctness is a consideration of whether your model produces sensible results. And there is more to modelling reality than just the laws of physics. Even the idea that there is some kind of external reality, that is the source of our experiences, is part of this model that gives us an explanation for why our experiences behave in the way they do. Ultimately, each of us needs to find a way of making sense of our experiences in a way that works for us. In that sense, Anything Goes.

I think that this way of thinking is revolutionary! Once we recognise that it’s all a matter of perspective – that there are no disembodied facts about the universe in any useful sense, we can make progress in all sorts of areas that have previously proved intractable. Does God exist? It depends on your model. Is Schrödinger’s Cat alive or dead? Well, from whose perspective? Schrödinger’s or the cat’s? How would we tell if an Artificial Intelligence model attained consciousness? 

In my book, in order to find answers to questions like this last one, I ask what it means to say that an entity that only exists as part of your model of reality has a mind of its own as well as whether solipsism could be true, what it’s like to be a bat and whether you could be a brain in a vat!



All these questions and more are addressed in Anything Goes – A Philosophical Approach to Answering the God Question, due to be released on Amazon on 3 June 2024.

And the Universe Shrugged




Posted by Keith Tidman

It’s not a question of whether humankind will become extinct, but when.

To be clear, I’m not talking about a devastatingly runaway climate; the predations of human beings on ecosystems; an asteroid slamming into Earth; a super-volcano erupting; a thermonuclear conflagration; a global contagion; rogue artificial intelligence; an eventual red-giant sun engulfing us; the pending collision of the Milky Way and Andromeda galaxies. Nor am I talking about the record of short-lived survival of our forerunners, like the Neanderthals, Denisovans, and Homo erectus, all of whom slid into extinction after unimpressive spans.

Rather, I’m speaking of cosmic death!

Cosmic death will occur according to standard physics, including cosmology. Because of the accelerating expansion of the universe and the irrepressibility of entropy — the headlong plunge toward evermore disorder and chaos — eventually no new stars will form, and existing stars will burn out. The universe will become uninhabitable long before its actual demise. Eventually a near vacuum will result. Particles that remain will be so unimaginably distanced from one another that they’ll seldom, if ever, interact. This is the ultimate end of the universe, when entropy reaches its maximum or so-called thermodynamic equilibrium, more descriptively dubbed ‘heat death’. There’s no place to duck; spacefaring won’t make a difference. Nowhere in the universe is immune.

Assuredly, heat death will take trillions of years to happen. However, might anyone imagine that the timeframe veils the true metaphysical significance of universal extinction, including the extinction of humans and all other conscious, intelligent life? And does it really make a difference if it’s tens of years or tens of trillions of years? Don’t the same ontological questions about being still searingly pertain, irrespective of timescale? Furthermore, does it really make a difference if this would be the so-called ‘sixth extinction’, or the thousandth, or the millionth, or the billionth? Again, don’t the same questions still pertain? There remains, amidst all this, the reality of finality. The consequences — the upshot of why this actuality matters to us existentially — stay the same, immune to time.

So, to ask ‘what is the meaning of life?’ — that old chestnut from inquiring minds through the millennia — likely becomes moot and even unanswerable, in the face of surefire universal extinction. As we contemplate the wafer-thin slice of time that makes up our eighty-or-so-year lifespans, the question seems to make a bit of sense. That select, very manageable timeframe puts us into our comfort zone; we can assure ourselves of meaning, to a degree. But the cosmological context of cosmic heat death contemptuously renders the question about life’s purpose without an answer; all bets are off. And, in face of cosmic thermodynamic death, it’s easy to shift to another chestnut: why, in light of all this, is there something rather than nothing? All this while we may justifiably stay in awe of the universe’s size and majesty, yet know the timing and inevitability of our own extinction rests deterministically in its hands.

A more suitable question might be whether we were given, evolutionarily, consciousness and higher-order intelligence for a reason, making it possible for us to reflect on and try to make sense of the universe. And where that ‘reason’ for our being might originate: an ethereal source, something intrinsic to the cosmos itself, or other. It’s possible that the answer is simply that humankind is incidental, consigning issues like beginnings to unimportance or even nonsense. After all, if the universe dies, and is itself therefore arguably incidental, we may be incidental, too. Again, the fact that the timeframe is huge is immaterial to these inquiries. Also immaterial is whether there might, hypothetically, be another, follow-on Big Bang. Whereby the cosmological process restarts, to include a set of natural physical laws, the possible evolution of intelligent life, and, let’s not overlook it, entropy all over again.

We compartmentalise our lives, to make sense of the bits and pieces that competitively and sometimes contradictorily impact us daily. And in the case of cosmic death and the extinction of life — ours and everyone else’s possibly dotting the universe — that event’s speck-like remoteness in distant time and the vastness of space understandably mollifies. This, despite the event’s unavoidability and hard-to-fathom, hard-to-internalise conclusiveness, existential warts and all. To include, one might suppose, the end of history, the end of physics, and the end of metaphysics! This end of everything might challenge claims to any singular specialness of our and other species, all jointly riding our home planets to this peculiar end. 

Perhaps we have no choice, in the meantime, to conduct ourselves in ways that reflect our belief systems and acknowledge the institutional tools (sociological, political, spiritual) used to referee those beliefs. As an everyday priority, we’ll surely continue to convert those beliefs into norms, to improve society and the quality of life in concrete, actionable ways. Those norms and institutions enable us to live an orderly existence — one that our minds can plumb and make rational sense of. Even though that may largely be a salve, it may be our best (realistically, only) default behaviour in contending with daily realities, ranging from the humdrum to the spectacular. We tend to practice what’s called ‘manic defence’, whereby people distract themselves by focusing on things other than what causes their anxiety and discomfort.

The alternative — to capitulate, falling back upon self-indulgent nihilism — is untenable, insupportable, and unsustainable. We are, after all, quite a resilient species. And we live every day with comparatively attainable horizons. There remains, moreover, a richness to our existence, when our existence is considered outside of extraordinary universal timeframes. Accordingly, we go on with our lives with optimism, not dwelling on the fact that something existential will eventually happen — our collective whistling past the graveyard, one might say. We seldom, if ever, factor this universal expiry date into our thinking — understandably so. There would be little to gain, on any practical level, in doing otherwise. Cosmic thermodynamic death, after all, doesn’t concern considerations of morality. Cosmic death is an amoral event, devoid of concerns about its rightness or wrongness. It will happen matter of factly.

Meanwhile, might the only response to cosmic extinction — and with it, our extinction — be for the universe and humanity to shrug?

PP #48: Philosophic Reflections on a Lunar View of Earth



This view taken  July 20, 1969,  from the Apollo 11 spacecraft shows the Earth rising
above the moon's horizon. (Image credit: NASA/JSC)

Posted by Keith Tidman

Half a century after the Apollo 11 astronauts stepped onto the heavily pockmarked moon, a quarter of a million miles away, much of the world has recently been savoring again the grandeur of the achievement. Reaffirmation of the ‘giant leap for mankind’ legendarily beamed back to Earth, and the ambitious revisualisation of our space-based destiny and vistas.

The feat symbolised humankind’s intrepid instincts. To venture into space, as Earth-bound explorers once riskily did across threatening oceans and landmasses. To satisfy a gnawing curiosity, placing footprints, as these resilient astronauts did, onto unknown and little-known shores. And in the doing, be in awe of the oneness and most-fundamental architecture of humanity — the very nature of our being.

From this comparatively short distance, Earth still looks startlingly small and lonely — even humble, given its cloaking by the atmosphere. Yet, humankind might discover it isn’t alone; the cosmos brims with habitable planets. In that endeavour, how might the image of our planet change, then, as cameras peel back even farther: from elsewhere in the Milky Way and well beyond? As distances in space turn into light-years.

As Earth shrinks with distance, does the meaningfulness of our planet and its inhabitants shrink in parallel, in the vast cosmic backdrop, contesting humankind’s immodestly self-styled honorific of ‘exceptional’? Does our reality change? Or do, say, the ‘volume and mass’ of what fundamentally matters about us — our purpose — rebelliously remain unaffected, defining our place in the larger scheme, no matter Earth’s size in the surrounding cold expanse? 

A rebelliousness that, one might submit, emerges from a web of human ‘consciousness’ that stretches around the planet — the neurons and synapses (connectomes) of seven-and-a-half billion people ceaselessly firing: the stuff of dreams, imaginings, creations. Integral, perhaps, to a larger cosmic consciousness: and again, the stuff of dreams, imaginings, creations.

The seeming peacefulness in the image at top is just that: ‘seeming’. The pacific panorama masks the true nature of Earth: roiling with both natural and human activity. The phantom tranquility conceals one of our instinctual human behaviours: successive wars filling millennia of history. One wonders what idiosyncratically in the human genome leads mankind to war to remedy differences and trifling grievances, as well as quench hegemonic cravings. All the while paradoxically juxtaposed with the astounding complexities of humankind’s diverse civilisations and cultures.

As we gaze, from moon’s vantage point, upon the orb of Earth, with its thin coating of air and water, we are reminded of how vulnerably brittle the Earth’s environment is. Especially at the environment’s intersections with not-uncommonly remorseless technology. Existential risks abound. We’re reminded of the responsibility humanity has as active (proactive) guardians, to nurture the planet as the planet symbiotically nurtures us. Critical, we might agree, to the survival and continued evolution of our species.

What happens if we misguidedly, even disinterestedly, poison or exhaust the planet, as it hangs precariously in space? Or might nature, perhaps indifferent to humanity and coolly subjecting us to its whim, itself render the planet uninhabitable — leading to another major extinction event? Are we only renters, not owners? Did the lunar visit introduce a new imperative: to leave Earth behind and inhabit somewhere else?

Is there a solemnity about the rearward-looking scene of a distanced Earth — an awe that prompts reflection? A scene made all the more evocative by our believing that Earth is immersed in a sort of cosmic sea — of dark matter, dark energy, quantum fluctuations, and more. Is there the perception of ‘aloneness’, too, our seemingly distanced from everyone and everything else in that cosmic sea? The silence of the gaping, inky space contrasts with the cacophony of Earth, the latter a hive of devices that magnify our voices and echo our presence. Will that cacophony continue, or ultimately go silent?

In that presence, we marvel that humankind, dwelling on the comparatively tiny planet seen from the lunar perspective, nevertheless has the cognitive wherewithal to ponder and increasingly understand the cosmology of the whole universe: its beginning, its evolution, its current circumstances, its future. A study in the making, propelled by an irresistible impulse to know.

Anyone whose culture might have included the pre-digital-age children’s game of marbles may nostalgically recognise, from this lunar distance, the surface appearance of Earth, with its gauzy, chaotically swirling patterns. We admire its familiarly abstract beauty. All the while suspecting that there’s order interweaving the deception of chaos. Surrounding this marble-like Earth is a bewildering stillness and blackness — a blackness majestically interrupted, however, by galaxies and stunning phenomena like the Pillars of Creation.

Future generations will grasp, better than us, how this one step on another cosmic body, however craggy and nearby the moon is, served to spur far more ambitious tours through space, whether by human beings or sophisticated thinking apparatuses — to face down the harsh environment of space as we inexorably scratch our exploratory itch.

Fermi's Paradox . . . But What If?


Posted by Keith Tidman

Seven decades ago, the physicist-of-atomic-bomb-fame, Enrico Fermi, pondered with his lunchtime companions at Los Alamos whether other intelligent life forms populate planets around the Milky Way, and if so, why we have no evidence of them? He purportedly asked, “Where are they?”, meaning, of course, the alien beings. Because if other complex, intelligent, technology-clever life forms have even a fraction of humankind’s proclivity toward curiosity and, let’s say, colonization, then why is there no evidence of them having acted on these instincts throughout our galaxy? From that conundrum, Fermi’s Paradox emerged.

The American astrophysicist, Frank Drake, later thought about which factors might be necessary to address Fermi’s question and, in particular, how many technological civilizations, emitting electromagnetic signals, might exist among the stars of just our galaxy alone. These became known as Drake’s Equation, and offer a way to calculate the number of civilizations in the Milky Way based on seven variables.* Although scientists can’t yet insert firm numbers for the variables, I think Drake’s effort remains a worthy first attempt at eventually quantifying an answer to Fermi’s question. Especially given that the physical laws of evolution could well differ among far-flung, unfamiliarly diverse chemical, biological, and physical conditions and constraints, yielding singularly different intelligent species.

Many ‘what if’ hypotheses exist by way of possible answers to Fermi’s deceptively simple question. For example, perhaps technology-based civilizations and species with sophisticated intelligence are too far separated by space and time, measured even in thousands of light-years to reveal any presence. Or perhaps, because of the finely grained conditions necessary for life with high intelligence to evolve (the ‘anthropic principle’), civilizations are so rare and scattered that it’s difficult to find each other. Certainly it seems that our own sending-receiving (and space-faring) technologies are too primitive to matter much yet in the sophisticated game of cosmic outreach. Or just perhaps other civilizations have spotted us, but regard humankind as too biologically and intellectually primitive a species to bother with whom to show their hand. Or perhaps they regard humankind as a prototypically warring species, never-endingly engaged in small-minded, lethal belligerence over territory, resources, and power. Perhaps all intelligent species tend toward self-isolating wariness that outweighs curiosity about ‘the other’. Perhaps Thucydides’ thesis that established and rising powers are compelled to go to war applies even on the interplanetary scale.

All that said, should there eventually be confirmation of alien intelligent species that are endowed with far higher levels of consciousness and intelligence than humankind — qualities having evolved over histories hundreds of thousands or millions of years older than ours — then the consequence would be culturally tectonic shifting. As a species, perhaps lulled by so easily triumphing over so many of our Earthly competitors, we’re prone to indulging in flights of ‘exceptionalism’. We’re predisposed to looking at our reflection in life’s mirror and — more often looking down, not up — seeing only reasons to preen over our capacity for rationality, creativity, and imagination. To be unseated, with a thud, by an alien species’ cognitive prowess — and the benefits to its civilization — could prove unsettling for humankind’s indulgences in unchallenged exceptionalism.

At the very least, discovery of our sudden non-uniqueness might compel reexamination of basic principles. It might lead to fundamentally questioning religious texts, customs, tenets, rituals, codes of morality, ‘spirituality’, and dicta. If so, the result may be to rethink and rewrite the underlying explanations and descriptions, widening out the aperture of religious philosophy and theology to take into account the new realities of not being alone in the galaxy and in larger cosmos. At the heart of such teleological investigation and reinvention might be questions, which never go away, about humankind’s purpose: about why we are here.

The stunning space-time topography of this universe isn’t hubristically ours alone. I venture it’s a matter of when, not whether, the ‘code’ to Fermi’s Paradox will be cracked.



*Drake’s equation, as in our image, is typically shown as follows:

N = R* fp ne fl fi fc L,

Here N is the number of civilizations in the Milky Way whose electromagnetic emissions are detectable; R* is the rate of formation of stars suitable for the development of intelligent life; fp is the fraction of those stars with planetary systems; ne is the number of planets, per solar system, with an environment suitable for life (the habitable, ‘Goldilocks’ zones around their suns); fl is the fraction of suitable planets on which life actually appears; fi is the fraction of life-bearing planets on which intelligent life emerges; fc is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space; and L is the length of time such civilizations release detectable signals into space.

Eastern and Western Philosophy: Personal Identity

With acknowledgement to the CeramiX Art Collection
Posted by John Hansen
Once, when our world was not so small, major philosophies rarely made contact with one another. Further, being embedded in different languages, different concepts, different cultures, and different religions, on the surface of it they seemed to hold little in common.  
Yet as our world has become smaller, and as scholars have devoted more careful attention to distant ideas, so we have discovered, to our surprise, that our philosophies may be much the same.

A case in point is David Hume, the Scottish philosopher of the 18th Century, and Vasubandhu, the Indian philosopher of (about) the 5th – in particular, their views on personal identity.

From one point of view, there were enormous differences between these two men. Hume was an agnostic, and probably an atheist. He was, in the words of Julian Baggini, ‘as godless a man as can be imagined.’ Vasubandhu, on the other hand, was deeply religious. He was a Buddhist monk who spent much of his life writing commentaries on the teachings of the Buddha.

Yet Hume and Vasubandhu came remarkably close, on core philosophical issues. How then did they diverge so completely on matters of religion? What may this tell us about philosophy – above all about metaphysics? But first, let us survey a few examples of the central concepts common to both men, in the area of personal identity.

Vasubandhu believed that the self is a continuum of 'aggregates', which are the physiological elements which constitute the individual person. Similarly, Hume equated the self with a conglomeration of perceptions, which are in a constant state of flux. Both Hume and Vasubandhu therefore believed that, because of the constant transition of our mental states, these are a part of a continuum that moves in temporal sequence from perception to perception.

Vasubandhu believed that one's memory of an object is aroused when a special function of the mind connects to, and identifies objects from, earlier occurrences. Similarly, Hume believed that whatever the changes a person’s mental state may go through, older perceptions influence newer, and the vehicle for continuity is found in our memory, which acquaints us with a succession of perceptions.

For Vasubandhu, the 'self' which possesses a memory is equivalent to that which generated the memory. He argues that the only constant is that of perceived causal connection. Hume, similarly, argues that our memory helps us discover our personal identity by showing us associations among our different perceptions – and these produce the impression of identity.

Vasubandhu, however, did not distinguish between material objects and our mental sensation of them. Hume, on the other hand, did separate the two. Therefore Vasubandhu presumed the existence of objects outside of our mental state of being – allowing for religious belief. But Hume focused almost entirely on empirical comparisons and observations, believing it to be an abuse of the notion of personal identity that the idea of an unchanging substance should be added to it.

Hume the skeptic, and Vasubandhu the monk. How did they come so close on core philosophical questions, yet on the basis of such vastly different presuppositions? How could they so completely diverge on matters of religion, while in basic concepts they so largely agreed? What was it that – as it were – switched on religious corollaries in Vasubandhu, and switched them off in Hume?

Was Hume right? Was Vasubandhu wrong? Were there cracks in the coherence of their philosophies? Did their very languages shape their conceptual associations? Do religious belief or godlessness serve as mere garnish to real philosophy? The answers could have crucial consequences for philosophy.

If Aristotle Visited Us Today

Posted by Eugene Alper
The term 'metaphysics' was born with Aristotle. He was the first who aspired to gathering together all previous philosophical knowledge, and integrating it in a single great work.
Perhaps he felt hopeful – as one might feel on a fresh morning in the woods, with the first rays of the sun filtering through the trees. Although he was teased by a few outstanding questions, perhaps Aristotle felt that the end was truly in sight.

Yet if Aristotle visited us today, he might conclude that philosophy is in major crisis. For we have been asking the same fundamental questions – the same perennial questions – for two and a half millennia. And because of that, he might note, we are in a less enviable position than he was. For accumulated knowledge without obvious fruit affects one’s sense of self-confidence. It also undermines hope: the more knowledge, the less hope.

It is natural for the teenager – by way of analogy – to be hopeful about the future, to think that by the age of forty she will certainly know how to live a life, as opposed to her parents who, for some reasons, still do not. But when the age comes, and the former teenager asks the same question and still finds no answer, and suspects something even worse—that at the age of fifty and sixty and seventy she may still have no answer—a sense of unease dawns on her. This is what they call midlife crisis.

One wonders whether Aristotle might see, in the philosophic state of humankind today, the same sort of midlife crisis. He himself had a limited literature or recorded history to look back upon – but we, he might observe, have 2 500 years. This long view of the well-recorded past might give him – as it gives us – a deep sense of unease.

On the one hand, seeing so much treasure accumulated in literature, poetry, drama, philosophy, one can reasonably say, 'Look at the baggage of fine thought we are bringing along. Does this not give hope that its accumulation in the future may be even greater, and that, just as we have seen in technology, there may soon come a qualitative breakthrough? Isn’t this the evidence that we may be onto something? Just one more step, just one more realisation, and we may understand what the good life is?'

On the other hand, this very outlook on the past shows that our thinking, in the most fundamental ways, does not improve with time. Like the bird which greets each morning with the same old song, we fail to recognise that there is nothing new, that our questions are not different from the questions already asked by Aristotle long ago, or better than the answers he already gave.

Our baggage today, Aristotle might observe, is dubious and heavy, for the very ability to know the past and to observe the distance one has travelled without much philosophic growth may make one lose heart. Our human thinking, he might conclude, is somewhat defective, somewhat limited by nature. It could be that, by nature, our mind is incapable of going beyond the Biblical God, Plato’s One, or Aristotle’s Primary Cause. Or it could be that, by nature, our mind does better when dealing with things measurable, yet not so well with things abstract.

Perhaps, then, there is no exiting from the loop, no jumping out of the rut. On the most fundamental issues we will still think in inescapable circles, resembling the fish in the bowl, who thinks it is moving forward while sliding along the concave glass.
