Toward the end of the Renaissance period, a radical epistemological and metaphysical shift overcame the Western psyche. The advances of Nicolaus Copernicus, Galileo Galilei and Francis Bacon posed a serious problem for Christian dogma and its dominion over the natural world. Following Bacon’s arguments, the natural world was now to be understood solely in terms of efficient causes (ie, external effects). Any inherent meaning or purpose to the natural world (ie, its ‘formal’ or ‘final’ causes) was deemed surplus to requirements. Insofar as it could be predicted and controlled in terms of efficient causes, not only was any notion of nature beyond this conception redundant, but God too could be effectively dispensed with.

In the 17th century, René Descartes’s dualism of matter and mind was an ingenious solution to the problem this created. ‘The ideas’ that had hitherto been understood as inhering in nature as ‘God’s thoughts’ were rescued from the advancing army of empirical science and withdrawn into the safety of a separate domain, ‘the mind’. On the one hand, this maintained a dimension proper to God, and on the other, served to ‘make the intellectual world safe for Copernicus and Galileo’, as the American philosopher Richard Rorty put it in Philosophy and the Mirror of Nature (1979). In one fell swoop, God’s substance-divinity was protected, while empirical science was given reign over nature-as-mechanism – something ungodly and therefore free game.

Nature was thereby drained of her inner life, rendered a deaf and blind apparatus of indifferent and value-free law, and humankind was faced with a world of inanimate, meaningless matter, upon which it projected its psyche – its aliveness, meaning and purpose – only in fantasy. It was this disenchanted vision of the world, at the dawn of the industrial revolution that followed, that the Romantics found so revolting, and feverishly revolted against.

The French philosopher Michel Foucault in The Order of Things (1966) termed it a shift in ‘episteme’ (roughly, a system of knowledge). The Western psyche, Foucault argued, had once been typified by ‘resemblance and similitude’. In this episteme, knowledge of the world was derived from participation and analogy (the ‘prose of the world’, as he called it), and the psyche was essentially extroverted and world-involved. But after the bifurcation of mind and nature, an episteme structured around ‘identity and difference’ came to possess the Western psyche. The episteme that now prevailed was, in Rorty’s terms, solely concerned with ‘truth as correspondence’ and ‘knowledge as accuracy of representations’. Psyche, as such, became essentially introverted and untangled from the world.

Foucault argued, however, that this move was not a supersession per se, but rather constituted an ‘othering’ of the prior experiential mode. As a result, its experiential and epistemological dimensions were not only denied validity as an experience, but became the ‘occasion of error’. Irrational experience (ie, experience inaccurately corresponding to the ‘objective’ world) then became a meaningless mistake – and disorder the perpetuation of that mistake. This is where Foucault located the beginning of the modern conception of ‘madness’.

Although Descartes’s dualism did not win the philosophical day, we in the West are still very much the children of the disenchanted bifurcation it ushered in. Our experience remains characterised by the separation of ‘mind’ and ‘nature’ instantiated by Descartes. Its present incarnation  – what we might call the empiricist-materialist position  –  not only predominates in academia, but in our everyday assumptions about ourselves and the world. This is particularly clear in the case of mental disorder.

Common notions of mental disorder remain only elaborations of ‘error’, conceived of in the language of ‘internal dysfunction’ relative to a mechanistic world devoid of any meaning and influence. These dysfunctions are either to be cured by psychopharmacology, or remedied by therapy meant to lead the patient to rediscover ‘objective truth’ of the world. To conceive of it in this way is not only simplistic, but highly biased.

While it is true that there is value in ‘normalising’ irrational experiences like this, it comes at a great cost. These interventions work (to the extent that they do) by emptying our irrational experiences of their intrinsic value or meaning. In doing so, not only are these experiences cut off from any world-meaning they might harbour, but so too from any agency and responsibility we or those around us have – they are only errors to be corrected.

In the previous episteme, before the bifurcation of mind and nature, irrational experiences were not just ‘error’ – they were speaking a language as meaningful as rational experiences, perhaps even more so. Imbued with the meaning and rhyme of nature herself, they were themselves pregnant with the amelioration of the suffering they brought. Within the world experienced this way, we had a ground, guide and container for our ‘irrationality’, but these crucial psychic presences vanished along with the withdrawal of nature’s inner life and the move to ‘identity and difference’.

In the face of an indifferent and unresponsive world that neglects to render our experience meaningful outside of our own minds  –  for nature-as-mechanism is powerless to do this  –  our minds have been left fixated on empty representations of a world that was once its source and being. All we have, if we are lucky to have them, are therapists and parents who try to take on what is, in reality, and given the magnitude of the loss, an impossible task.

But I’m not going to argue that we just need to ‘go back’ somehow. On the contrary, the bifurcation of mind and nature was at the root of immeasurable secular progress –  medical and technological advance, the rise of individual rights and social justice, to name just a few. It also protected us all from being bound up in the inherent uncertainty and flux of nature. It gave us a certain omnipotence – just as it gave science empirical control over nature – and most of us readily accept, and willingly spend, the inheritance bequeathed by it, and rightly so.

It cannot be emphasised enough, however, that this history is much less a ‘linear progress’ and much more a dialectic. Just as unified psyche-nature stunted material progress, material progress has now degenerated psyche. Perhaps, then, we might argue for a new swing in this pendulum. Given the dramatic increase in substance-use issues and recent reports of a teenage ‘mental health crisis’ and teen suicide rates rising in the US, the UK and elsewhere to name only the most conspicuous, perhaps the time is in fact overripe.

However, one might ask, by what means? There has been a resurgence of ‘pan-experiential’ and idealist-leaning theories in several disciplines, largely concerned with undoing the very knot of bifurcation and the excommunication of a living nature, and creating in its wake something afresh. This is because attempts at explaining subjective experience in empiricist-materialist terms have all but failed (principally due to what the Australian philosopher David Chalmers in 1995 termed the ‘the hard problem’ of consciousness). The notion that metaphysics is ‘dead’ would in fact be met with very significant qualification in certain quarters – indeed, the Canadian philosopher Evan Thompson et al argued along the same lines in a recent essay in Aeon.

It must be remembered that mental disorder as ‘error’ rises and falls with the empiricist-materialist metaphysics and the episteme it is a product of. Therefore, we might also think it justified to begin to reconceptualise the notion of mental disorder in the same terms as these theories. There has been a decisive shift in psychotherapeutic theory and practice away from the changing of parts or structures of the individual, and towards the idea that it is the very process of the therapeutic encounter itself that is ameliorative. Here, correct or incorrect judgments about ‘objective reality’ start to lose meaning, and psyche as open and organic starts to come back into focus, but the metaphysics remains. We ultimately need to be thinking about mental disorder on a metaphysical level, and not just within the confines of the status quo.Aeon counter – do not remove

Philosophical Writing Should Read like a Letter Written to Oneself

kierkegaard2

Søren Kierkegaard at his high desk (1920) by Luplau Janssen. Courtesy Wikipedia

John Lysaker | Aeon Ideas

In memory of Stanley Cavell (1926-2018)

I came to philosophy bursting with things to say. Somewhere along the way, that changed. Not that I stopped talking, or, as time went on, writing. But the mood of it, the key in which it was pitched, moved. I came to feel answerable. And not just to myself or those I knew but to some broader public, some open, indefinite ‘you’. ‘Answer for yourself’ wove into ‘know thyself’.

How though does one register a key change in prose? If philosophy is bound, in part, to the feeling of being answerable, shouldn’t it have more of an epistolary feel? ‘Dear you, here is where I stand, for the time being… Yours, me.’ One ventures thoughts, accounts for them and awaits a reply, only to begin again: ‘Dear you, thank you for your response. So much (or very little) has changed since I received your letter…’

A move toward the epistolary seems right to me, at least for philosophy. Still a gadfly perhaps, but also working through having been stung, and with the vulnerability of doing so before, even for others. But how much philosophy has the feel of a letter? And when we philosophise, are we cognisant of our addressees and the varied situations in which they find us? The view from nowhere has been more or less exiled from epistemology. We know that we know in concrete, situated locales. But has philosophical writing kept pace and developed a feel for what to consider when pondering: how should I write?

Survey philosophy’s history, and the plot thickens. Philosophical writing is a varied affair. Some texts prioritise demonstration, arguing, for example, that ‘truth’ names a working touch between belief and the world. Others favour provocation, as when a dialogue concerning the nature of friendship concludes before a working definition is reached. If we want a definition, we need to generate our own, or ponder what a lack of one implies. Still other texts offer exemplification, as when Simone de Beauvoir in The Second Sex (1949) proves herself to be the agent-intellect that patriarchy insists she’s not. By confronting her historical fate, she shows us how wrong, how unjust that historical fate has been. And she shows us what patriarchy has kept us from.

Genre considerations intensify the question of what should organise philosophical writing: dialogue, treatise, aphorism, essay, professional article and monograph, fragment, autobiography. And if one’s sensibility is more inclusive, letters, manifestos and interviews also become possibilities. No genre is fully scripted, however, hence the need to also consider logical-rhetorical operations: modus ponens, irony, transcendental arguments, allegory, images, analogies, examples, quotations, translation, even voice, a distinctive way of being there and for the reader. So much seems to count when we answer for how we write.

Questions concerning writing sometimes arise when philosophers worry about accessibility and a broader readership. But the possibilities I have enumerated bear directly on thought itself. Writing generates discovery, and genre impacts rather than simply transfers ideas; so too logical-rhetorical operations. Francis Bacon was drawn to the aphorism because it freed observation from scholastic habits, whereas the professional article defers to its lingua franca. The treatise exhausts whatever might be said about a topic – call this the view from everywhere – whereas the essay accepts its partiality and tests its reach relative to topics such as friendship, feminine sexuality, even a fierce love for film. When writing becomes the question, more than outreach calls for consideration.

Here’s a start. How will my thought unfold through this genre and these logical-rhetorical operations? Where will the aphorism, essay or professional article take me, or an exchange of letters? And so too examples, open disagreements, quotation, the labour of translation, or irony for that matter? It is a celebrated trope of surprise and displacement. But a good deal of irony, at least when one turns to the ironist, facilitates self-preservation. It is the reader who is surprised by an encounter with some covert meaning while the author’s overt and covert meanings are fairly settled. (I thus wonder: what does irony keep safe?)

Questions regarding which possibilities to enact cannot be answered through critique, which, following Immanuel Kant, interrogates the character of our judgments and operative concepts, seeking rules that might govern their use. The discoveries that writing occasions are evidence that philosophy belongs too intimately to language to play charioteer to its steeds. Writing is a gamble and, when it’s honest, one faces unexpected results.

Facing a blank page, one might also ask: what relations will this establish with addressees? The polemic seeks converts rather than interlocutors, and at the expense of discovery. And even when an outright polemic is avoided, some schematise opponents rather than read them publicly and carefully, thereby preaching to the converted, which seems a misstep.

Unwilling to proceed dogmatically, one might favour provocation at the expense of doctrine, as some take Plato to do. But any provocation has its own commitments, beginning with the end toward which it provokes its readers. Socrates is one kind of interlocutor, Gaius Laelius quite another, and that is because Plato and Cicero approach education, the soul and their respective states differently. Strict distinctions between provocation and doctrine (or form and content, for that matter) are thus untenable.

Other operations also engage one’s addressees. Examples allow readers to review what’s on offer, something also made possible when meaningful disagreements are staged. (When authors never pause to imagine a disagreement, I feel claustrophobic and throw open a window.) And if one begins to acknowledge how varied one’s addressees could be, other habits become salient. Looking back at my citations, I know that I’ve written texts that suggest ‘whites only’ or ‘women need not apply’.

Texts and readers do not meet in a vacuum, however. I thus wonder: how does one also address prevailing contextual forces, from ethno-nationalisms to white supremacy to the commodification of higher education? It is tempting to imagine a text without footnotes, as if they were ornaments. But in a period so averse to the rigours of knowledge, and so ahistorical in its feel for the truths we have, why not underscore the contested history of a thought, if only to insist: thought is work, the results fragile, and there will be disagreements. Clarity poses another question, and a particular challenge for philosophy, which is not underwritten by experiments. Instead, its ‘results’ are won (or lost) in the presentation. Moreover, philosophical conclusions do not remain philosophical if freed from the path that led to them. ‘God exists’ says one thing in prayer and something else at the close of a proof. Experts often are asked to share their results without showing their work. But showing one’s work is very much the work of philosophy. Can one do so and reach beyond the academy?

Every reader of Plato knows that Socrates, by way of exemplification, is an image of philosophy, from his modes of interrogation to who is interrogated to his reminders that philosophy demands courage. And so too the dialogue itself – it models philosophy. But every text announces: here too is philosophy. The overall bearing of one’s writing thus merits scrutiny. Is it generous or hasty? Has it earned its ‘therefores’ or, after ripping opponents for nuanced failings, does it invoke the intuitively plausible? Does it acknowledge the full range of possible addressees or cloister itself within the narrow folds of the like-minded? Does it challenge its starting points or hide cut corners with jargon and massive generalisations?

Taking my cue from Ludwig Wittgenstein, I would say: philosophy no longer knows its way around writing. And what it does know – the professional article and monograph – is underwritten by conformity rather than philosophical reflection and commitment. Not for all. And many have led elsewhere by example. But on the whole, and thinking of the present moment, the writer’s life remains unexamined in the aspirational context of philosophy.

Looking into a garden of genres and logical-rhetorical operations, I have proposed four orienting questions. How will my thought unfold along these lines? What relationships will they establish with my varied addressees? Will my address be able to navigate the currents of our varied lives and be ‘equal to the moment’, as Walter Benjamin would ask? And finally, what, in the name of philosophy, does my text exemplify? Have I offered a compelling image? ‘Dear you, here is where I stand, for the time being… Yours, me.’Aeon counter – do not remove

Atheism has been Part of Many Asian Traditions for Millennia

File 20190328 139361 138qhpw.jpg?ixlib=rb 1.1

Atheism is not a modern concept.

Signe Cohen, University of Missouri-Columbia

A group of atheists and secularists recently gathered in Southern California to talk about social and political issues. This was the first of three summits planned by the Secular Coalition for America, an advocacy group based in Washington D.C.

To many, atheism – the lack of belief in a personal god or gods – may appear an entirely modern concept. After all, it would seem that it is religious traditions that have dominated the world since the beginning of recorded history.

As a scholar of Asian religions, however, I’m often struck by the prevalence of atheism and agnosticism – the view that it is impossible to know whether a god exists – in ancient Asian texts. Atheistic traditions have played a significant part in Asian cultures for millennia.

Atheism in Buddhism, Jainism

Buddhists do not believe in a creator God.
Keith Cuddeback, CC BY-NC-ND

While Buddhism is a tradition focused on spiritual liberation, it is not a theistic religion.

The Buddha himself rejected the idea of a creator god, and Buddhist philosophers have even argued that belief in an eternal god is nothing but a distraction for humans seeking enlightenment.

While Buddhism does not argue that gods don’t exist, gods are seen as completely irrelevant to those who strive for enlightenment.

Jains do not believe in a divine creator.
Gandalf’s Gallery, CC BY-NC-SA

A similar form of functional atheism can also be found in the ancient Asian religion of Jainism, a tradition that emphasizes non-violence toward all living beings, non-attachment to worldly possessions and ascetic practice. While Jains believe in an eternal soul or jiva, that can be reborn, they do not believe in a divine creator.

According to Jainism, the universe is eternal, and while gods may exist, they too must be reborn, just like humans are. The gods play no role in spiritual liberation and enlightenment; humans must find their own path to enlightenment with the help of wise human teachers.

Other Atheistic Philosophies

Around the same time when Buddhism and Jainism arose in the sixth century B.C., there was also an explicitly atheist school of thought in India called the Carvaka school. Although none of their original texts have survived, Buddhist and Hindu authors describe the Carvakas as firm atheists who believed that nothing existed beyond the material world.

To the Carvakas, there was no life after death, no soul apart from the body, no gods and no world other than this one.

Another school of thought, Ajivika, which flourished around the same time, similarly argued that gods didn’t exist, although its followers did believe in a soul and in rebirth.

The Ajivikas claimed that the fate of the soul was determined by fate alone, and not by a god, or even by free will. The Ajivikas taught that everything was made up of atoms, but that these atoms were moving and combining with each other in predestined ways.

Like the Carvaka school, the Ajivika school is today only known from texts composed by Hindus, Buddhists and Jains. It is therefore difficult to determine exactly what the Ajivikas themselves thought.

According to Buddhist texts, the Ajivikas argued that there was no distinction between good and evil and there was no such thing as sin. The school may have existed around the same time as early Buddhism, in the fifth century B.C.

Atheism in Hinduism

There are many gods in Hinduism, but there are also atheistic beliefs.
Religious Studies Unisa, CC BY-SA

While the Hindu tradition of India embraces the belief in many gods and goddesses – 330 million of them, according to some sources – there are also atheistic strands of thought found within Hinduism.

The Samkhya school of Hindu philosophy is one such example. It believes that humans can achieve liberation for themselves by freeing their own spirit from the realm of matter.

Another example is the Mimamsa school. This school also rejects the idea of a creator God. The Mimamsa philosopher Kumarila said that if a god had created the world by himself in the beginning, how could anyone else possibly confirm it? Kumarila further argued that if a merciful god had created the world, it could not have been as full of suffering as it is.

According to the 2011 census, there were approximately 2.9 million atheists in India. Atheism is still a significant cultural force in India, as well as in other Asian countries influenced by Indian religions.The Conversation

Is Consciousness a Battle between your Beliefs and Perceptions?

elephant-magic

Imagine you’re at a magic show, in which the performer suddenly vanishes. Of course, you ultimately know that the person is probably just hiding somewhere. Yet it continues to look as if the person has disappeared. We can’t reason away that appearance, no matter what logic dictates. Why are our conscious experiences so stubborn?

The fact that our perception of the world appears to be so intransigent, however much we might reflect on it, tells us something unique about how our brains are wired. Compare the magician scenario with how we usually process information. Say you have five friends who tell you it’s raining outside, and one weather website indicating that it isn’t. You’d probably just consider the website to be wrong and write it off. But when it comes to conscious perception, there seems to be something strangely persistent about what we see, hear and feel. Even when a perceptual experience is clearly ‘wrong’, we can’t just mute it.

Why is that so? Recent advances in artificial intelligence (AI) shed new light on this puzzle. In computer science, we know that neural networks for pattern-recognition – so-called deep learning models – can benefit from a process known as predictive coding. Instead of just taking in information passively, from the bottom up, networks can make top-down hypotheses about the world, to be tested against observations. They generally work better this way. When a neural network identifies a cat, for example, it first develops a model that allows it to predict or imagine what a cat looks like. It can then examine any incoming data that arrives to see whether or not it fits that expectation.

The trouble is, while these generative models can be super efficient once they’re up and running, they usually demand huge amounts of time and information to train. One solution is to use generative adversarial networks (GANs) – hailed as the ‘coolest idea in deep learning in the last 20 years’ by Facebook’s head of AI research Yann LeCun. In GANs, we might train one network (the generator) to create pictures of cats, mimicking real cats as closely as it can. And we train another network (the discriminator) to distinguish between the manufactured cat images and the real ones. We can then pit the two networks against each other, such that the discriminator is rewarded for catching fakes, while the generator is rewarded for getting away with them. When they are set up to compete, the networks grow together in prowess, not unlike an arch art-forger trying to outwit an art expert. This makes learning very efficient for each of them.

As well as a handy engineering trick, GANs are a potentially useful analogy for understanding the human brain. In mammalian brains, the neurons responsible for encoding perceptual information serve multiple purposes. For example, the neurons that fire when you see a cat also fire when you imagine or remember a cat; they can also activate more or less at random. So whenever there’s activity in our neural circuitry, the brain needs to be able to figure out the cause of the signals, whether internal or external.

We can call this exercise perceptual reality monitoring. John Locke, the 17th-century British philosopher, believed that we had some sort of inner organ that performed the job of sensory self-monitoring. But critics of Locke wondered why Mother Nature would take the trouble to grow a whole separate organ, on top of a system that’s already set up to detect the world via the senses. You have to be able to smell something before you can go about deciding whether or not the perception is real or fake; so why not just build in a check to the detecting mechanism itself?

In light of what we now know about GANs, though, Locke’s idea makes a certain amount of sense. Because our perceptual system takes up neural resources, parts of it get recycled for different uses. So imagining a cat draws on the same neuronal patterns as actually seeing one. But this overlap muddies the water regarding the meaning of the signals. Therefore, for the recycling scheme to work well, we need a discriminator to decide when we are seeing something versus when we’re merely thinking about it. This GAN-like inner sense organ – or something like it – needs to be there to act as an adversarial rival, to stimulate the growth of a well-honed predictive coding mechanism.

If this account is right, it’s fair to say that conscious experience is probably akin to a kind of logical inference. That is, if the perceptual signal from the generator says there is a cat, and the discriminator decides that this signal truthfully reflects the state of the world right now, we naturally see a cat. The same goes for raw feelings: pain can feel sharp, even when we know full well that nothing is poking at us, and patients can report feeling pain in limbs that have already been amputated. To the extent that the discriminator gets things right most of the time, we tend to trust it. No wonder that when there’s a conflict between subjective impressions and rational beliefs, it seems to make sense to believe what we consciously experience.

This perceptual stubbornness is not just a feature of humans. Some primates have it too, as shown by their capacity to be amazed and amused by magic tricks. That is, they seem to understand that there’s a tension between what they’re seeing and what they know to be true. Given what we understand about their brains – specifically, that their perceptual neurons are also ‘recyclable’ for top-down functioning – the GAN theory suggests that these nonhuman animals probably have conscious experiences not dissimilar to ours.

The future of AI is more challenging. If we built a robot with a very complex GAN-style architecture, would it be conscious? On the basis of our theory, it would probably be capable of predictive coding, exercising the same machinery for perception as it deploys for top-down prediction or imagination. Perhaps like some current generative networks, it could ‘dream’. Like us, it probably couldn’t reason away its pain – and it might even be able to appreciate stage magic.

Theorising about consciousness is notoriously hard, and we don’t yet know what it really consists in. So we wouldn’t be in a position to establish if our robot was truly conscious. Then again, we can’t do this with any certainty with respect to other animals either. At least by fleshing out some conjectures about the machinery of consciousness, we can begin
to test them against our intuitions – and, more importantly, in experiments. What we do know is that a model of the mind involving an inner mechanism of doubt – a nit-picking system that’s constantly on the lookout for fakes and forgeries in perception – is one of the most promising ideas we’ve come up with so far.

Was the Real Socrates more Worldly and Amorous than We Knew?

socrates-alcibiades-aspasia

Detail from Socrates Dragging Alcibiades from the Embrace of Aspasia (1785) by Jean-Baptiste Regnault. Louvre, Paris. Courtesy Wikipedia

Armand D’Angour | Aeon Ideas

Socrates is widely considered to be the founding figure of Western philosophy – a thinker whose ideas, transmitted by the extensive writings of his devoted follower Plato, have shaped thinking for more than 2,000 years. ‘For better or worse,’ wrote the Classical scholar Diskin Clay in Platonic Questions (2000), ‘Plato’s Socrates is our Socrates.’ The enduring image of Socrates that comes from Plato is of a man of humble background, little education, few means and unappealing looks, who became a brilliant and disputatious philosopher married to an argumentative woman called Xanthippe. Both Plato and Xenophon, Socrates’ other principal biographer, were born c424 BCE, so they knew Socrates (born c469 BCE) only as an old man. Keen to defend his reputation from the charges of ‘introducing new kinds of gods’ and ‘corrupting young men’ on which he was eventually brought to trial and executed, they painted a picture of Socrates in late middle age as a pious teacher and unremitting ethical thinker, a man committed to shunning bodily pleasures for higher educational purposes.

Yet this clearly idealised picture of Socrates is not the whole story, and it gives us no indication of the genesis of his ideas. Plato’s pupil Aristotle and other Ancient writers provide us with correctives to the Platonic Socrates. For instance, Aristotle’s followers Aristoxenus and Clearchus of Soli preserve biographical snippets that they might have known from their teacher. From them we learn that Socrates in his teens was intimate with a distinguished older philosopher, Archelaus; that he married more than once, the first time to an aristocratic woman called Myrto, with whom he had two sons; and that he had an affair with Aspasia of Miletus, the clever and influential woman who was later to become the partner of Pericles, a leading citizen of Athens.

If these statements are to be believed, a different Socrates emerges: that of a highly placed young Athenian, whose personal experiences within an elevated milieu inspired him to embark on a new style of philosophy that was to change the way people thought ever afterwards. But can we trust these later authors? How could writers two or more generations removed from Socrates’ own time have felt entitled to contradict Plato? One answer is that Aristotle might have derived some information from Plato in person, rather than from his writings, and passed this on to his pupils; another is that, as a member of Plato’s Academy for 20 years, Aristotle might have known that Plato had elided certain facts to defend Socrates’ reputation; a third is that the later authors had access to further sources (oral and written) other than Plato, which they considered to be reliable.

Plato’s Socrates is an eccentric. Socrates claimed to have heard voices in his head from youth, and is described as standing still in public places for long stretches of time, deep in thought. Plato notes these phenomena without comment, accepting Socrates’ own description of the voices as his ‘divine sign’, and reporting on his awe-inspiring ability to meditate for hours on end. Aristotle, the son of a doctor, took a more medical approach: he suggested that Socrates (along with other thinkers) suffered from a medical condition he calls ‘melancholy’. Recent medical investigators have agreed, speculating that Socrates’ behaviour was consistent with a medical condition known as catalepsy. Such a condition might well have made Socrates feel estranged from his peers in early life, encouraging him to embark on a different kind of lifestyle.

If the received picture of Socrates’ life and personality merits reconsid­eration, what about his thought? Aristotle makes clear in his Metaphysics that Plato misrepresented Socrates regarding the so-called Theory of Forms:

Socrates concerned himself with ethics, neglecting the natural world but seeking the universal in ethical matters, and he was the first to insist on definitions. Plato took over this doctrine, but argued that what was universal applied not to objects of sense but to entities of another kind. He thought a single description could not define things that are perceived, since such things are always changing. Unchanging entities he called ‘Forms’…

Aristotle himself had little sympathy for such otherwordly views. As a biologist and scientist, he was mainly concerned with the empirical investigation of the world. In his own writings he dismissed the Forms, replacing them with a logical account of universals and their particular instantiations. For him, Socrates was also a more down-to-earth thinker than Plato sought to depict.

Sources from late antiquity, such as the 5th-century CE Christian writers Theodoret of Cyrrhus and Cyril of Alexandria, state that Socrates was, at least as a younger man, a lover of both sexes. They corroborate occasional glimpses of an earthy Socrates in Plato’s own writings, such as in the dialogue Charmides where Socrates claims to be intensely aroused by the sight of a young man’s bare chest. However, the only partner of Socrates’ whom Plato names is Xanthippe; but since she was carrying a baby in her arms when Socrates was aged 70, it is unlikely they met more than a decade or so earlier, when Socrates was already in his 50s. Plato’s failure to mention the earlier aristocratic wife Myrto might be an attempt to minimise any perception that Socrates came from a relatively wealthy background with connections to high-ranking members of his community; it was largely because Socrates was believed to be associated with the antidemocratic aristocrats who took power in Athens that he was put on trial and executed in 399 BCE.

Aristotle’s testimony, therefore, is a valuable reminder that the picture of Socrates bequeathed by Plato should not be accepted uncritically. Above all, if Socrates at some point in his early manhood became the companion of Aspasia – a woman famous as an instructor of eloquence and relationship counsellor – it potentially changes our understanding not only of Socrates’ early life, but of the formation of his philosophical ideas. He is famous for saying: ‘All I know is that I know nothing.’ But the one thing he claims, in Plato’s Symposium, that he does know about, is love, which he learned about from a clever woman. Might that woman have been Aspasia, once his beloved companion? The real Socrates must remain elusive but, in the statements of Aristotle, Aristoxenus and Clearchus of Soli, we get intriguing glimpses of a different Socrates from the one portrayed so eloquently in Plato’s writings.

The Matrix 20 Years On: How a Sci-fi Film Tackled Big Philosophical Questions

The Matrix was a box office hit, but it also explored some of western philosophy’s most interesting themes.

Incredible as it may seem, the end of March marks 20 years since the release of the first film in the Matrix franchise directed by The Wachowski siblings. This “cyberpunk” sci-fi movie was a box office hit with its dystopian futuristic vision, distinctive fashion sense, and slick, innovative action sequences. But it was also a catalyst for popular discussion around some very big philosophical themes.

The film centres on a computer hacker, “Neo” (played by Keanu Reeves), who learns that his whole life has been lived within an elaborate, simulated reality. This computer-generated dream world was designed by an artificial intelligence of human creation, which industrially farms human bodies for energy while distracting them via a relatively pleasant parallel reality called the “matrix”.

‘Have you ever had a dream, Neo, that you were so sure was real?’

This scenario recalls one of western philosophy’s most enduring thought experiments. In a famous passage from Plato’s Republic (ca 380 BCE), Plato has us imagine the human condition as being like a group of prisoners who have lived their lives underground and shackled, so that their experience of reality is limited to shadows projected onto their cave wall.

A freed prisoner, Plato suggests, would be startled to discover the truth about reality, and blinded by the brilliance of the sun. Should he return below, his companions would have no means to understand what he has experienced and surely think him mad. Leaving the captivity of ignorance is difficult.

In The Matrix, Neo is freed by rebel leader Morpheus (ironically, the name of the Greek God of sleep) by being awoken to real life for the first time. But unlike Plato’s prisoner, who discovers the “higher” reality beyond his cave, the world that awaits Neo is both desolate and horrifying.

Our Fallible Senses

The Matrix also trades on more recent philosophical questions famously posed by the 17th century Frenchman René Descartes, concerning our inability to be certain about the evidence of our senses, and our capacity to know anything definite about the world as it really is.

Descartes even noted the difficulty of being certain that human experience is not the result of either a dream or a malevolent systematic deception.

The latter scenario was updated in philosopher Hilary Putnam’s 1981 “brain in a vat” thought experiment, which imagines a scientist electrically manipulating a brain to induce sensations of normal life.

So ultimately, then, what is reality? The late 20th century French thinker Jean Baudrillard, whose book appears briefly (with an ironic touch) early in the film, wrote extensively on the ways in which contemporary mass society generates sophisticated imitations of reality that become so realistic they are mistaken for reality itself (like mistaking the map for the landscape, or the portrait for the person).

Of course, there is no need for a matrix-like AI conspiracy to achieve this. We see it now, perhaps even more intensely than 20 years ago, in the dominance of “reality TV” and curated identities of social media.

In some respects, the film appears to be reaching for a view close to that of the 18th century German philosopher, Immanuel Kant, who insisted that our senses do not simply copy the world; rather, reality conforms to the terms of our perception. We only ever experience the world as it is available through the partial spectrum of our senses.

The Ethics of Freedom

Ultimately, the Matrix trilogy proclaims that free individuals can change the future. But how should that freedom be exercised?

This dilemma is unfolded in the first film’s increasingly notorious red/blue pill scene, which raises the ethics of belief. Neo’s choice is to embrace either the “really real” (as exemplified by the red pill he is offered by Morpheus) or to return to his more normal “reality” (via the blue one).

This quandary was captured in a 1974 thought experiment by American philosopher, Robert Nozick. Given an “experience machine” capable of providing whatever experiences we desire, in a way indistinguishable from “real” ones, should we stubbornly prefer the truth of reality? Or can we feel free to reside within comfortable illusion?

In The Matrix we see the rebels resolutely rejecting the comforts of the matrix, preferring grim reality. But we also see the rebel traitor Cypher (Joe Pantoliano) desperately seeking reinsertion into pleasant simulated reality. “Ignorance is bliss,” he affirms.

The film’s chief villain, Agent Smith (Hugo Weaving), darkly notes that unlike other mammals, (western) humanity insatiably consumes natural resources. The matrix, he suggests, is a “cure” for this human “contagion”.

We have heard much about the potential perils of AI, but perhaps there is something in Agent Smith’s accusation. In raising this tension, The Matrix still strikes a nerve – especially after 20 further years of insatiable consumption.The Conversation

A Philosophical Approach to Routines can Illuminate Who We Really Are

Elias Anttila | Aeon Ideas

There are hundreds of things we do – repeatedly, routinely – every day. We wake up, check our phones, eat our meals, brush our teeth, do our jobs, satisfy our addictions. In recent years, such habitual actions have become an arena for self-improvement: bookshelves are saturated with bestsellers about ‘life hacks’, ‘life design’ and how to ‘gamify’ our long-term projects, promising everything from enhanced productivity to a healthier diet and huge fortunes. These guides vary in scientific accuracy, but they tend to depict habits as routines that follow a repeated sequence of behaviours, into which we can intervene to set ourselves on a more desirable track.

The problem is that this account has been bleached of much of its historical richness. Today’s self-help books have in fact inherited a highly contingent version of habit – specifically, one that arises in the work of early 20th-century psychologists such as B F Skinner, Clark Hull, John B Watson and Ivan Pavlov. These thinkers are associated with behaviourism, an approach to psychology that prioritises observable, stimulus-response reactions over the role of inner feelings or thoughts. The behaviourists defined habits in a narrow, individualistic sense; they believed that people were conditioned to respond automatically to certain cues, which produced repeated cycles of action and reward.

The behaviourist image of habit has since been updated in light of contemporary neuroscience. For example, the fact that the brain is plastic and changeable allows habits to inscribe themselves in our neural wiring over time by forming privileged connections between brain regions. The influence of behaviourism has enabled researchers to study habits quantitatively and rigorously. But it has also bequeathed a flattened notion of habit that overlooks the concept’s wider philosophical implications.

Philosophers used to look at habits as ways of contemplating who we are, what it means to have faith, and why our daily routines reveal something about the world at large. In his Nicomachean Ethics, Aristotle uses the terms hexis and ethos – both translated today as ‘habit’ – to study stable qualities in people and things, especially regarding their morals and intellect. Hexis denotes the lasting characteristics of a person or thing, like the smoothness of a table or the kindness of a friend, which can guide our actions and emotions. A hexis is a characteristic, capacity or disposition that one ‘owns’; its etymology is the Greek word ekhein, the term for ownership. For Aristotle, a person’s character is ultimately a sum of their hexeis (plural).

An ethos, on the other hand, is what allows one to develop hexeis. It is both a way of life and the basic calibre of one’s personality. Ethos is what gives rise to the essential principles that help to guide moral and intellectual development. Honing hexeis out of an ethos thus takes both time and practice. This version of habit fits with the tenor of ancient Greek philosophy, which often emphasised the cultivation of virtue as a path to the ethical life.

Millennia later, in medieval Christian Europe, Aristotle’s hexis was Latinised into habitus. The translation tracks a shift away from the virtue ethics of the Ancients towards Christian morality, by which habit acquired distinctly divine connotations. In the middle ages, Christian ethics moved away from the idea of merely shaping one’s moral dispositions, and proceeded instead from the belief that ethical character was handed down by God. In this way, the desired habitus should become entwined with the exercise of Christian virtue.

The great theologian Thomas Aquinas saw habit as a vital component of spiritual life. According to his Summa Theologica (1265-1274), habitus involved a rational choice, and led the true believer to a sense of faithful freedom. By contrast, Aquinas used consuetudo to refer to the habits we acquire that inhibit this freedom: the irreligious, quotidian routines that do not actively engage with faith. Consuetudo signifies mere association and regularity, whereas habitus conveys sincere thoughtfulness and consciousness of God. Consuetudo is also where we derive the terms ‘custom’ and ‘costume’ – a lineage which suggests that the medievals considered habit to extend beyond single individuals.

For the Enlightenment philosopher David Hume, these ancient and medieval interpretations of habit were far too limiting. Hume conceived of habit via what it empowers and enables us to do as human beings. He came to the conclusion that habit is the ‘cement of the universe’, which all ‘operations of the mind … depend on’. For instance, we might throw a ball in the air and watch it rise and descend to Earth. By habit, we come to associate these actions and perceptions – the movement of our limb, the trajectory of the ball – in a way that eventually lets us grasp the relationship between cause and effect. Causality, for Hume, is little more than habitual association. Likewise language, music, relationships – any skills we use to transform experiences into something that’s useful are built from habits, he believed. Habits are thus crucial instruments that enable us to navigate the world and to understand the principles by which it operates. For Hume, habit is nothing less than the ‘great guide of human life’.

It’s clear that we ought to see habits as more than mere routines, tendencies and ticks. They encompass our identities and ethics; they teach us how to practise our faiths; if Hume is to believed, they do no less than bind the world together. Seeing habits in this new-yet-old way requires a certain conceptual and historical about-face, but this U-turn offers much more than shallow self-help. It should show us that the things we do every day aren’t just routines to be hacked, but windows through which we might glimpse who we truly are.Aeon counter – do not remove

Ibn Tufayl and the Story of the Feral Child of Philosophy

Marwa Elshakry & Murad Idris | Aeon Ideas

Ibn Tufayl, a 12th-century Andalusian, fashioned the feral child in philosophy. His story Hayy ibn Yaqzan is the tale of a child raised by a doe on an unnamed Indian Ocean island. Hayy ibn Yaqzan (literally ‘Living Son of Awakeness’) reaches a state of perfect, ecstatic understanding of the world. A meditation on the possibilities (and pitfalls) of the quest for the good life, Hayy offers not one, but two ‘utopias’: a eutopia (εὖ ‘good’, τόπος ‘place’) of the mind in perfect isolation, and an ethical community under the rule of law. Each has a version of human happiness. Ibn Tufayl pits them against each other, but each unfolds ‘no where’ (οὐ ‘not’, τόπος ‘place’) in the world.

Ibn Tufayl begins with a vision of humanity isolated from society and politics. (Modern European political theorists who employed this literary device called it ‘the state of nature’.) He introduces Hayy by speculating about his origin. Whether Hayy was placed in a basket by his mother to sail through the waters of life (like Moses) or born by spontaneous generation on the island is irrelevant, Ibn Tufayl says. His divine station remains the same, as does much of his life, spent in the company only of animals. Later philosophers held that society elevates humanity from its natural animal state to an advanced, civilised one. Ibn Tufayl took a different view. He maintained that humans can be perfected only outside society, through a progress of the soul, not the species.

In contrast to Thomas Hobbes’s view that ‘man is a wolf to man’, Hayy’s island has no wolves. It proves easy enough for him to fend off other creatures by waving sticks at them or donning terrifying costumes of hides and feathers. For Hobbes, the fear of violent death is the origin of the social contract and the apologia for the state; but Hayy’s first encounter with fear of death is when his doe-mother dies. Desperate to revive her, Hayy dissects her heart only to find one of its chambers is empty. The coroner-turned-theologian concludes that what he loved in his mother no longer resides in her body. Death therefore was the first lesson of metaphysics, not politics.

Hayy then observes the island’s plants and animals. He meditates upon the idea of an elemental, ‘vital spirit’ upon discovering fire. Pondering the plurality of matter leads him to conclude that it must originate from a singular, non-corporeal source or First Cause. He notes the perfect motion of the celestial spheres and begins a series of ascetic exercises (such as spinning until dizzy) to emulate this hidden, universal order. By the age of 50, he retreats from the physical world, meditating in his cave until, finally, he attains a state of ecstatic illumination. Reason, for Ibn Tufayl, is thus no absolute guide to Truth.

The difference between Hayy’s ecstatic journeys of the mind and later rationalist political thought is the role of reason. Yet many later modern European commentaries or translations of Hayy confuse this by framing the allegory in terms of reason. In 1671, Edward Pococke entitled his Latin translation The Self-Taught Philosopher: In Which It Is Demonstrated How Human Reason Can Ascend from Contemplation of the Inferior to Knowledge of the Superior. In 1708, Simon Ockley’s English translation was The Improvement of Human Reason, and it too emphasised reason’s capacity to attain ‘knowledge of God’. For Ibn Tufayl, however, true knowledge of God and the world – as a eutopia for the ‘mind’ (or soul) – could come only through perfect contemplative intuition, not absolute rational thought.

This is Ibn Tufayl’s first utopia: an uninhabited island where a feral philosopher retreats to a cave to reach ecstasy through contemplation and withdrawal from the world. Friedrich Nietzsche’s Zarathustra would be impressed: ‘Flee, my friend, into your solitude!’

The rest of the allegory introduces the problem of communal life and a second utopia. After Hayy achieves his perfect condition, an ascetic is shipwrecked on his island. Hayy is surprised to discover another being who so resembles him. Curiosity leads him to befriend the wanderer, Absal. Absal teaches Hayy language, and describes the mores of his own island’s law-abiding people. The two men determine that the islanders’ religion is a lesser version of the Truth that Hayy discovered, shrouded in symbols and parables. Hayy is driven by compassion to teach them the Truth. They travel to Absal’s home.

The encounter is disastrous. Absal’s islanders feel compelled by their ethical principles of hospitality towards foreigners, friendship with Absal, and association with all people to welcome Hayy. But soon Hayy’s constant attempts to preach irritate them. Hayy realises that they are incapable of understanding. They are driven by satisfactions of the body, not the mind. There can be no perfect society because not everyone can achieve a state of perfection in their soul. Illumination is possible only for the select, in accordance with a sacred order, or a hieros archein. (This hierarchy of being and knowing is a fundamental message of neo-Platonism.) Hayy concludes that persuading people away from their ‘natural’ stations would only corrupt them further. The laws that the ‘masses’ venerate, be they revealed or reasoned, he decides, are their only chance to achieve a good life.

The islanders’ ideals – lawfulness, hospitality, friendship, association – might seem reasonable, but these too exist ‘no where’ in the world. Hence their dilemma: either they adhere to these and endure Hayy’s criticisms, or violate them by shunning him. This is a radical critique of the law and its ethical principles: they are normatively necessary for social life yet inherently contradictory and impossible. It’s a sly reproach of political life, one whose bite endures. Like the islanders, we follow principles that can undermine themselves. To be hospitable, we must be open to the stranger who violates hospitality. To be democratic, we must include those who are antidemocratic. To be worldly, our encounters with other people must be opportunities to learn from them, not just about them.

In the end, Hayy returns to his island with Absal, where they enjoy a life of ecstatic contemplation unto death. They abandon the search for a perfect society of laws. Their eutopia is the quest of the mind left unto itself, beyond the imperfections of language, law and ethics – perhaps beyond even life itself.

The islanders offer a less obvious lesson: our ideals and principles undermine themselves, but this is itself necessary for political life. For an island of pure ethics and law is an impossible utopia. Perhaps, like Ibn Tufayl, all we can say on the search for happiness is (quoting Al-Ghazali):

It was – what it was is harder to say.
Think the best, but don’t make me describe it away.

After all, we don’t know what happened to Hayy and Absal after their deaths – or to the islanders after they left.Aeon counter – do not remove

Descartes was Wrong: ‘A Person is a Person through Other Persons’

Abeba Birhane | Aeon Ideas

According to Ubuntu philosophy, which has its origins in ancient Africa, a newborn baby is not a person. People are born without ‘ena’, or selfhood, and instead must acquire it through interactions and experiences over time. So the ‘self’/‘other’ distinction that’s axiomatic in Western philosophy is much blurrier in Ubuntu thought. As the Kenyan-born philosopher John Mbiti put it in African Religions and Philosophy (1975): ‘I am because we are, and since we are, therefore I am.’

We know from everyday experience that a person is partly forged in the crucible of community. Relationships inform self-understanding. Who I am depends on many ‘others’: my family, my friends, my culture, my work colleagues. The self I take grocery shopping, say, differs in her actions and behaviours from the self that talks to my PhD supervisor. Even my most private and personal reflections are entangled with the perspectives and voices of different people, be it those who agree with me, those who criticise, or those who praise me.

Yet the notion of a fluctuating and ambiguous self can be disconcerting. We can chalk up this discomfort, in large part, to René Descartes. The 17th-century French philosopher believed that a human being was essentially self-contained and self-sufficient; an inherently rational, mind-bound subject, who ought to encounter the world outside her head with skepticism. While Descartes didn’t single-handedly create the modern mind, he went a long way towards defining its contours.

Descartes had set himself a very particular puzzle to solve. He wanted to find a stable point of view from which to look on the world without relying on God-decreed wisdoms; a place from which he could discern the permanent structures beneath the changeable phenomena of nature. But Descartes believed that there was a trade-off between certainty and a kind of social, worldly richness. The only thing you can be certain of is your own cogito – the fact that you are thinking. Other people and other things are inherently fickle and erratic. So they must have nothing to do with the basic constitution of the knowing self, which is a necessarily detached, coherent and contemplative whole.

Few respected philosophers and psychologists would identify as strict Cartesian dualists, in the sense of believing that mind and matter are completely separate. But the Cartesian cogito is still everywhere you look. The experimental design of memory testing, for example, tends to proceed from the assumption that it’s possible to draw a sharp distinction between the self and the world. If memory simply lives inside the skull, then it’s perfectly acceptable to remove a person from her everyday environment and relationships, and to test her recall using flashcards or screens in the artificial confines of a lab. A person is considered a standalone entity, irrespective of her surroundings, inscribed in the brain as a series of cognitive processes. Memory must be simply something you have, not something you do within a certain context.

Social psychology purports to examine the relationship between cognition and society. But even then, the investigation often presumes that a collective of Cartesian subjects are the real focus of the enquiry, not selves that co-evolve with others over time. In the 1960s, the American psychologists John Darley and Bibb Latané became interested in the murder of Kitty Genovese, a young white woman who had been stabbed and assaulted on her way home one night in New York. Multiple people had witnessed the crime but none stepped in to prevent it. Darley and Latané designed a series of experiments in which they simulated a crisis, such as an epileptic fit, or smoke billowing in from the next room, to observe what people did. They were the first to identify the so-called ‘bystander effect’, in which people seem to respond more slowly to someone in distress if others are around.

Darley and Latané suggested that this might come from a ‘diffusion of responsibility’, in which the obligation to react is diluted across a bigger group of people. But as the American psychologist Frances Cherry argued in The Stubborn Particulars of Social Psychology: Essays on the Research Process (1995), this numerical approach wipes away vital contextual information that might help to understand people’s real motives. Genovese’s murder had to be seen against a backdrop in which violence against women was not taken seriously, Cherry said, and in which people were reluctant to step into what might have been a domestic dispute. Moreover, the murder of a poor black woman would have attracted far less subsequent media interest. But Darley and Latané’s focus make structural factors much harder to see.

Is there a way of reconciling these two accounts of the self – the relational, world-embracing version, and the autonomous, inward one? The 20th-century Russian philosopher Mikhail Bakhtin believed that the answer lay in dialogue. We need others in order to evaluate our own existence and construct a coherent self-image. Think of that luminous moment when a poet captures something you’d felt but had never articulated; or when you’d struggled to summarise your thoughts, but they crystallised in conversation with a friend. Bakhtin believed that it was only through an encounter with another person that you could come to appreciate your own unique perspective and see yourself as a whole entity. By ‘looking through the screen of the other’s soul,’ he wrote, ‘I vivify my exterior.’ Selfhood and knowledge are evolving and dynamic; the self is never finished – it is an open book.

So reality is not simply out there, waiting to be uncovered. ‘Truth is not born nor is it to be found inside the head of an individual person, it is born between people collectively searching for truth, in the process of their dialogic interaction,’ Bakhtin wrote in Problems of Dostoevsky’s Poetics (1929). Nothing simply is itself, outside the matrix of relationships in which it appears. Instead, being is an act or event that must happen in the space between the self and the world.

Accepting that others are vital to our self-perception is a corrective to the limitations of the Cartesian view. Consider two different models of child psychology. Jean Piaget’s theory of cognitive development conceives of individual growth in a Cartesian fashion, as the reorganisation of mental processes. The developing child is depicted as a lone learner – an inventive scientist, struggling independently to make sense of the world. By contrast, ‘dialogical’ theories, brought to life in experiments such as Lisa Freund’s ‘doll house study’ from 1990, emphasise interactions between the child and the adult who can provide ‘scaffolding’ for how she understands the world.

A grimmer example might be solitary confinement in prisons. The punishment was originally designed to encourage introspection: to turn the prisoner’s thoughts inward, to prompt her to reflect on her crimes, and to eventually help her return to society as a morally cleansed citizen. A perfect policy for the reform of Cartesian individuals. But, in fact, studies of such prisoners suggest that their sense of self dissolves if they are punished this way for long enough. Prisoners tend to suffer profound physical and psychological difficulties, such as confusion, anxiety, insomnia, feelings of inadequacy, and a distorted sense of time. Deprived of contact and interaction – the external perspective needed to consummate and sustain a coherent self-image – a person risks disappearing into non-existence.

The emerging fields of embodied and enactive cognition have started to take dialogic models of the self more seriously. But for the most part, scientific psychology is only too willing to adopt individualistic Cartesian assumptions that cut away the webbing that ties the self to others. There is a Zulu phrase, ‘Umuntu ngumuntu ngabantu’, which means ‘A person is a person through other persons.’ This is a richer and better account, I think, than ‘I think, therefore I am.’Aeon counter – do not remove

The Concept of Probability is not as Simple as You Think

probability

Nevin Climenhaga | Aeon Ideas

The gambler, the quantum physicist and the juror all reason about probabilities: the probability of winning, of a radioactive atom decaying, of a defendant’s guilt. But despite their ubiquity, experts dispute just what probabilities are. This leads to disagreements on how to reason about, and with, probabilities – disagreements that our cognitive biases can exacerbate, such as our tendency to ignore evidence that runs counter to a hypothesis we favour. Clarifying the nature of probability, then, can help to improve our reasoning.

Three popular theories analyse probabilities as either frequencies, propensities or degrees of belief. Suppose I tell you that a coin has a 50 per cent probability of landing heads up. These theories, respectively, say that this is:

  • The frequency with which that coin lands heads;
  • The propensity, or tendency, that the coin’s physical characteristics give it to land heads;
  • How confident I am that it lands heads.

But each of these interpretations faces problems. Consider the following case:

Adam flips a fair coin that self-destructs after being tossed four times. Adam’s friends Beth, Charles and Dave are present, but blindfolded. After the fourth flip, Beth says: ‘The probability that the coin landed heads the first time is 50 per cent.’

Adam then tells his friends that the coin landed heads three times out of four. Charles says: ‘The probability that the coin landed heads the first time is 75 per cent.’

Dave, despite having the same information as Charles, says: ‘I disagree. The probability that the coin landed heads the first time is 60 per cent.’

The frequency interpretation struggles with Beth’s assertion. The frequency with which the coin lands heads is three out of four, and it can never be tossed again. Still, it seems that Beth was right: the probability that the coin landed heads the first time is 50 per cent.

Meanwhile, the propensity interpretation falters on Charles’s assertion. Since the coin is fair, it had an equal propensity to land heads or tails. Yet Charles also seems right to say that the probability that the coin landed heads the first time is 75 per cent.

The confidence interpretation makes sense of the first two assertions, holding that they express Beth and Charles’s confidence that the coin landed heads. But consider Dave’s assertion. When Dave says that the probability that the coin landed heads is 60 per cent, he says something false. But if Dave really is 60 per cent confident that the coin landed heads, then on the confidence interpretation, he has said something true – he has truly reported how certain he is.

Some philosophers think that such cases support a pluralistic approach in which there are multiple kinds of probabilities. My own view is that we should adopt a fourth interpretation – a degree-of-support interpretation.

Here, probabilities are understood as relations of evidential support between propositions. ‘The probability of X given Y’ is the degree to which Y supports the truth of X. When we speak of ‘the probability of X’ on its own, this is shorthand for the probability of X conditional on any background information we have. When Beth says that there is a 50 per cent probability that the coin landed heads, she means that this is the probability that it lands heads conditional on the information that it was tossed and some information about its construction (for example, it being symmetrical).

Relative to different information, however, the proposition that the coin landed heads has a different probability. When Charles says that there is a 75 per cent probability that the coin landed heads, he means this is the probability that it landed heads relative to the information that three of four tosses landed heads. Meanwhile, Dave says there is a 60 per cent probability that the coin landed heads, relative to this same information – but since this information in fact supports heads more strongly than 60 per cent, what Dave says is false.

The degree-of-support interpretation incorporates what’s right about each of our first three approaches while correcting their problems. It captures the connection between probabilities and degrees of confidence. It does this not by identifying them – instead, it takes degrees of belief to be rationally constrained by degrees of support. The reason I should be 50 per cent confident that a coin lands heads, if all I know about it is that it is symmetrical, is because this is the degree to which my evidence supports this hypothesis.

Similarly, the degree-of-support interpretation allows the information that the coin landed heads with a 75 per cent frequency to make it 75 per cent probable that it landed heads on any particular toss. It captures the connection between frequencies and probabilities but, unlike the frequency interpretation, it denies that frequencies and probabilities are the same thing. Instead, probabilities sometimes relate claims about frequencies to claims about specific individuals.

Finally, the degree-of-support interpretation analyses the propensity of the coin to land heads as a relation between, on the one hand, propositions about the construction of the coin and, on the other, the proposition that it lands heads. That is, it concerns the degree to which the coin’s construction predicts the coin’s behaviour. More generally, propensities link claims about causes and claims about effects – eg, a description of an atom’s intrinsic characteristics and the hypothesis that it decays.

Because they turn probabilities into different kinds of entities, our four theories offer divergent advice on how to figure out the values of probabilities. The first three interpretations (frequency, propensity and confidence) try to make probabilities things we can observe – through counting, experimentation or introspection. By contrast, degrees of support seem to be what philosophers call ‘abstract entities’ – neither in the world nor in our minds. While we know that a coin is symmetrical by observation, we know that the proposition ‘this coin is symmetrical’ supports the propositions ‘this coin lands heads’ and ‘this coin lands tails’ to equal degrees in the same way we know that ‘this coin lands heads’ entails ‘this coin lands heads or tails’: by thinking.

But a skeptic might point out that coin tosses are easy. Suppose we’re on a jury. How are we supposed to figure out the probability that the defendant committed the murder, so as to see whether there can be reasonable doubt about his guilt?

Answer: think more. First, ask: what is our evidence? What we want to figure out is how strongly this evidence supports the hypothesis that the defendant is guilty. Perhaps our salient evidence is that the defendant’s fingerprints are on the gun used to kill the victim.

Then, ask: can we use the mathematical rules of probability to break down the probability of our hypothesis in light of the evidence into more tractable probabilities? Here we are concerned with the probability of a cause (the defendant committing the murder) given an effect (his fingerprints being on the murder weapon). Bayes’s theorem lets us calculate this as a function of three further probabilities: the prior probability of the cause, the probability of the effect given this cause, and the probability of the effect without this cause.

Since this is all relative to any background information we have, the first probability (of the cause) is informed by what we know about the defendant’s motives, means and opportunity. We can get a handle on the third probability (of the effect without the cause) by breaking down the possibility that the defendant is innocent into other possible causes of the victim’s death, and asking how probable each is, and how probable they make it that the defendant’s fingerprints would be on the gun. We will eventually reach probabilities that we cannot break down any further. At this point, we might search for general principles to guide our assignments of probabilities, or we might rely on intuitive judgments, as we do in the coin cases.

When we are reasoning about criminals rather than coins, this process is unlikely to lead to convergence on precise probabilities. But there’s no alternative. We can’t resolve disagreements about how much the information we possess supports a hypothesis just by gathering more information. Instead, we can make progress only by way of philosophical reflection on the space of possibilities, the information we have, and how strongly it supports some possibilities over others.Aeon counter – do not remove
