progressivism: the no-alternative philosophy

Canto: So here’s the thing – I’ve occasionally been asked about my politics and I’ve been a little discomfited about having to describe them in a few words, and I’ve even wondered if I could describe them effectively to myself.
Jacinta: Yes I find it easier to be sure of what I’m opposed to, such as bullies or authoritarians, which to me are much the same thing. So that means authoritarian governments, controlling governments and so forth. But I also learned early on that the world was unfair, that some kids were richer than others, smarter than others, better-looking than others, through no fault or effort of their own. I was even able to think through this enough to realise that even the kind kids and the nasty ones, the bullies and the scaredy-cats, didn’t have too much choice in the matter. So I often wondered about a government role in making things a bit fairer for those who lost out in exactly where, or into whose hands, they were thrown into the world.
Canto: Well you could say there’s a natural diversity in all those things, intelligence, appearance, wealth, capability and so forth… I’m not sure if it’s a good thing or a bad thing, it just is. I remember once answering that question, about my politics, by describing myself as a pluralist, and then later being disappointed at my self-description. Of course, I wouldn’t want to favour the opposite – what’s that, singularism? But clearly not all differences are beneficial – extreme poverty for example, or its opposite…
Jacinta: You wouldn’t want to be extremely wealthy?
Canto; Well okay I’ve sometimes fantasised, but mainly in terms of then having more power to make changes in the world. But I’m thinking of the differences that disadvantage us as a group, as a political entity. And here’s one thing I do know about politics. We can’t live without it. We owe our success as a species, for what it’s worth, to our socio-political organisation, something many libertarians seem to be in denial about.
Jacinta: Yes, humans are political animals, if I may improve upon Aristotle. But differences that disadvantage us. Remember eugenics? Perhaps in some ways it’s still with us. Prospective parents might be able to abort their child if they can find out early on that it’s – defective in some way.
Canto: Oh dear, that’s a real can of worms, but those weren’t the kind of differences I was thinking about. Since you raise the subject though, I would say this is a matter of individual choice, but that, overall, ridding the world of those kinds of differences – intellectual disability, dwarfism, intersex, blindness, deafness and so on – wouldn’t be a good thing. But of course that would require a sociopolitical world that would agree with me on that and be supportive of those differences.
Jacinta: So you’re talking about political differences. Or maybe cultural differences?
Canto: Yes but that’s another can of worms. It’s true that multiculturalism can expand our thinking in many ways, but you must admit that there are some heavy cultures, that have attitudes about the ‘place of women’ for example, or about necessary belief in their god…
Jacinta: Or that taurans make better lovers than geminis haha.
Canto: Haha, maybe. Some false beliefs have more serious consequences than others. So multiculturalism has its positives and negatives, but you want the dominant culture, or the mix of cultures that ultimately forms a new kind of ‘creole’ overarching culture, to be positive and open. To be progressive. That’s the key word. There’s no valid alternative to a progressive culture. It’s what has gotten us where we are, and that’s not such a bad place, though it’s far from perfect, and always will be.
Jacinta: So progressiveness good, conservativism bad? Is that it?
Canto: Nothing is ever so simple, but you’re on the right track. Progress is a movement forward. Sometimes it’s a little zigzaggy, sometimes two forward one back. I’m taking my cue from David Deutsch’s book The beginning of infinity, which is crystallising much I’ve thought about politics and culture over the years, and of the role and meaning of science, which as you know has long preoccupied me. Anyway, the opposite of progress is essentially stasis – no change at all. Our former conservative Prime Minister John Howard was fond of sagely saying ‘if it ain’t broke, don’t fix it’, as a way of avoiding the prospect of change. But it isn’t just about fixing, it’s rather more about improving, or transcending. Landline phones didn’t need fixing, they were a functional, functioning technology. But a new technology came along that improved upon it, and kept improving and added internet technology to its portability. We took a step back in our progress many decades ago, methinks, when we abandoned the promise of electrified modes of travel for the infernal combustion engine, and it’s taking us too long to get back on track, but I’m confident we’ll get there eventually. ..
Jacinta: I get you. Stasis is this safe option, but in fact it doesn’t lead anywhere. We’d be sticking with the ‘old’ way of doing things, which takes us back much further than just the days of landlines, but before any recognisable technology at all. Before using woven cloth, before even using animal skins and fire to improve our chances of survival.
Canto: So it’s not even a safe option. It’s not a viable option at all. You know how there was a drastic drop in the numbers of Homo sapiens some 70,000 years ago – we’ll probably never know how close we came to extinction. I’d bet my life it was some innovation that only our species could have thought of that enabled us to come out of it alive and breeding.
Jacinta: And some of our ancestors would’ve been dragged kicking and screaming towards accepting that innovation. I used to spend time on a forum of topical essays where the comments were dominated by an ‘anti-Enlightenment’ crowd, characters who thought the Enlightenment – presumably the eighteenth century European one (but probably also the British seventeenth century one, the Scottish one, and maybe even the Renaissance to boot) – was the greatest disaster ever suffered by humanity. Needless to say, I soon lost interest. But that’s an extreme example (I think they were religious nutters).
Canto: Deutsch, in a central chapter of The beginning of infinity, compares ancient Athens and Sparta, even employing a Socratic dialogue for local colour. The contrast isn’t just between Athens’ embracing of progress and Sparta’s determination to maintain stasis, but between openness and its opposite. Athens, at its all-too-brief flowering, encouraged philosophical debate and reasoning, rule-breaking artistry, experimentation and general questioning, in the process producing famous dialogues, plays and extraordinary monuments such as the Parthenon. Sparta on the other hand left no legacy to build on or rediscover, and all that we know of its politico-social system comes from non-Spartans, so that if it has been misrepresented it only has itself to blame!
Jacinta: Yet it didn’t last.
Canto: Many instances of that sort of thing. In the case of Athens, its disastrous Syracusan adventure, its ravagement by the plague, or a plague, or a series of plagues, and the Peloponnesian war, all combined to permanently arrest its development. Contingent events. Think too of the Islamic Golden Age, a long period of innovation in mathematics, physics, astronomy, medicine, architecture and much else, brought to an end largely by the Mongol invasions, and the collapse of the Abbasid caliphate but also by a political backlash towards stasis, anti-intellectualism and religiosity, most often associated with the 12th century theologian Abu Hamid al-Ghazali.
Jacinta: Very tragic for our modern world. So how do we guard against the apostles of stasis? By the interminable application of reason? By somehow keeping them off the reins of power, since those apostles will always be with us?
Canto: Not by coercion, no. It has to be a battle of ideas, or maybe I shouldn’t use that sort of male lingo. A demonstration of ideas, in the open market. A demonstration of their effectiveness for improving our world, which means comprehending that world at an ever-deeper, more comprehensive level.
Jacinta: Comprehensively comprehending, that seems commendably comprehensible. But will this improve the world for us all – lift all boats, as Sam Harris likes to say?
Canto: Well, since you mention Harris, I totally agree with him that reason, and science which is so clearly founded on reason, is just as applicable to the moral world, to pointing the way to and developing the best and richest life we all can live, as it is to technology and our deepest understanding of the universe, the multiverse or whatever our fundamental reality happens to be. So we need to keep on developing and building on that science, and communicating it and applying it to the human world and all that it depends upon and influences.

random thoughts on progress and culture

I seem to have a mind geared toward progress. I look forward (as I’m just beginning to feel my age) towards electric vehicles increasing market share in the ‘backward’ land of Oz. I look forward to governments here throwing their weight behind renewables without the usual reservations. I look forward to the James Webb telescope finally being launched, learning more about exoplanets, and of course genomics, epigenetics, neurophysiology, human origins, and much more. I look forward to the collapse of the Kim monarchy in North Korea, the demise of the current batch of macho political thugs worldwide, and the continuing rise to power of women in politics, business, science and technology. I’ve read Pinker’s two big books on the virtues of progress and enlightenment, I’m reading David Deutsch’s book on the beginning of an infinity of knowledge and discovery and technological improvement, and I’m wishing I could live at least another hundred years to watch the two-steps-forward-one step-back dance into the future.
And yet.
I generally describe myself as a humanist, and I’m drawn to those expressing suspicion and a degree of disdain toward nationalism – but, why is that? Am I free to have those feelings, which have been more or less with me since childhood, or have they been imposed on me by experiences I didn’t choose to have? After all, I’m human but I’m thoroughly localised in time and space. I’m a product, of a particular culture, often described as the dominant culture, white (though my skin is light brown and variable as I tan easily), Anglo-Saxon (though being born in the north-east of Scotland I may have Pictish and/or Scandinavian forebears, and frankly I’m not interested in tracing my ancestry) and protestant (though I’m not religious in any sense). Clearly, if I was born in the same place but several hundred years earlier, I wouldn’t be banging on about progress. I wouldn’t have ended up in Australia and I would likely never have travelled more than a few miles from the town of Dundee, where I was born. Whatever occupation I had wouldn’t have differed greatly from that of my father or my son, if I had one.
So much for time. Think of place. Had I been born in Australia a few hundred years ago, I would’ve been what Europeans call an Aborigine or an indigenous Australian – but I should get with the program, they’re called first nations people now, presumably because we now know that we’re all actually indigenous to the African continent. In any case, my world would’ve been unimaginably different. Or I might’ve been born to first nation parents, but in the fifties (that’s to say, on my actual birth date), in which case I would’ve experienced a mixture of Aboriginal and Western/European/White Australian culture. Again, an experience nigh impossible for me to imagine. How, in that case, would I think of nationalism, as someone linked to a ‘nation’ with an ancient, resilient culture, or complex of different cultures, but surrounded by an innovative, progressive, dominant culture that I would never quite belong to. Would I want to belong to it? Who can say – I’m mixing generalisations with particular experiences here, and it’s not making sense.
So it’s perhaps better, or certainly easier, to take the self out of the picture and think of cultures in the way we think of species and sub-species. Some species have found a niche, in the depths of the oceans, say, which has allowed them to survive and even thrive in a basic sort of way for eons, pretty well unchanged. Others, like rats and pigeons, have adapted to a variety of conditions, allowing them to spread across the globe, in tandem with ever-urbanising homo sapiens. Do we value all these species equally? Do we value all human cultures equally? We’re generally encouraged to think positively about biodiversity and cultural diversity. Yet we know that by far the majority of species mothered by this planet are now extinct. Many cultures, too, have been obliterated, by war, climate change, absorption into more dominant cultures and so forth. Which brings me back to progress. There seems to be a tension between the drive to preserve and the drive to transcend. There appears to be room for both drives much of the time, but what if they clash?
I recently had cause to learn a little more about the Andaman Islanders, who have a distinct and clearly self-sustaining culture developed over millenia. They don’t want to be disturbed and they’ve largely been granted that wish. After all, our progressive culture has no great need of their small scraps of land and what, from our perspective, are their meagre resources. However, imagine that something was discovered, via the latest in sophisticated computer technology, not too far beneath the soil of those islands – some mineral with extraordinary properties, valuable beyond measure to the dominant society’s continued technological advancement, but the extraction of which would massively disrupt the everyday life and compromise the spiritual beliefs of the islanders?
Perhaps this is a far-fetched scenario – it’s highly unlikely that, with our multi-faceted ingenuity, we would need to rely on some particular item from a remote set of islands for our juggernaut progress. And yet – I’ve read, in Simon Winchester’s book Pacific – of the fate of the Marshall Islanders in the forties and fifties, as the USA chose to use their region as the site of scores of nuclear tests, causing widespread and more or less permanent radioactive contamination – the price of a particular kind of progress. As Wikipedia puts it:
The testing concluded in 1958. Over the years, just one of over 60 islands was cleaned by the US government, and the inhabitants are still waiting for the 2 billion dollars in compensation assessed by the Nuclear Claims Tribunal. Many of the islanders and their descendants still live in exile, as the islands remain contaminated with high levels of radiation
Mistakes were made…
The ‘new world’ (meaning new to Europeans) and its first nations cultures have paid a heavy price for largely European colonisation, domination and progress. My position, as a somewhat low-ranking beneficiary of the dominant culture, makes it hard to judge the costs and benefits of these developments. We will go forward, but we need to look back at what we’ve done, and to look around at what we’re doing now. Preservation and progress is an uneasy balancing act which we’ll probably never quite master, but we need to keep trying, for humanity’s sake.

interactional reasoning: some stray thoughts

I mentioned in my first post on this topic, bumble-bees have a fast-and-frugal way of obtaining the necessary from flowers while avoiding predators, such as spiders, which is essentially about ‘assessing’ the relative cost of a false negative (sensing there’s no spider when there is) and a false positive (sensing there’s a spider when there’s not). Clearly, the cost of a false negative is likely death, but a false positive also has a cost in wasting time and energy in the search for safe flowers. It’s better to be safe than sorry, up to a point. The bees still have a job to do, which is their raison d’être. So they’ve evolved to be wary of certain rough-and-ready signs of a spider’s presence. It’s not a fool-proof system, but it ensures that false positives are a little more over-determined than false negatives, enough to ensure overall survival, at least against one particular threat.
When I’m walking on the street and note that a smoker is approaching, I have an immediate impulse, more or less conscious, to give her a wide berth, and even cross the road if possible. I suffer from bronchiectasis, an airways condition, which is much exacerbated by smoke, dust and other particulates. So it’s an eminently reasonable decision, or impulse (or something between the two). I must admit, though, that this event is generally accompanied by feelings of annoyance and disgust, and thoughts such as ‘smokers are such losers’ – in spite of the fact than, in the long long ago, I was a smoker myself.
Such negative thoughts, though, are self-preservative in much the same way as my avoidance measures. However, they’re not particularly ‘rational’ from the perspective of the intellectualist view of reason. I would do better, of course, in an interactive setting, because I’ve learned – through interactions of a sort (such as my recent reading of Siddhartha Mukherjee’s brilliant cancer book, which in turn sent me to the website of the US Surgeon-General’s report on smoking, and through other readings on the nature of addiction) – to have a much more nuanced and informed view. Stiil, my ‘smokers are losers’ disgust and disdain is perfectly adequate for my own everyday purposes!
The point is, of course, that reason evolved first and foremost to promote our survival, but further evolved, in our highly social species, to enable us to impress and influence others. And others have develped their own sophisticated reasons to impress and influence us. It follows that the best and most fruitful reasoning comes via interactions – collaborative or argumentative, in the best sense – with our peers. Of course, as I’ve stated it here, this is a hypothesis, and it’s quite hard to prove definitively. We’re all familiar with the apparently solitary geniuses – the Newtons, Darwins and Einsteins – who’ve transformed our understanding, and those who’ve been exposed to it will be impressed with the rigour of Aristotelian and post-Aristotelian logic, and the concepts of validity and soundness as the sine qua non of good reasoning (not to mention those fearfully absolute terms, rational and irrational). Yet these supposedly solitary geniuses often admitted themselves that they ‘stood on the shoulders of giants’, Einstein often mentioned his indebtedness to other thinkers, and Darwin’s correspondence was voluminous. Science is more than ever today a collaborative or competitively interactive process. Think also of the mathematician Paul Erdős whose obsessive interest in this most rational of activities led to a record number of collaborations.
These are mostly my own off-the-cuff thoughts. I’ll return to Mercier and Sperber’s writings on the evolution of reasoning and its modular nature next time.
preliminary thoughts on reasoning and reputation

In my youth I learned about syllogisms and modus ponens and modus tollens and the invalidity of arguments ad hominem and reductio ad absurdum, and valid but unsound arguments and deduction and induction and all the rest, and even wrote pages filled with ps and qs to get myself clear about it all, and then forgot about it. All that stuff was only rarely applied to everyday life, where, it seemed, our reasoning, though important, was more implicit and intuitive. What I did notice though – being a bit of a loner – was that when I did have a disagreement with someone which left a bitter taste in my mouth, I would afterwards go over the argument in my head to make it stronger, more comprehensive, more convincing and bullet-proof (and of course I would rarely get the chance to present this new and improved version). But interestingly, as part of this process, I would generally make my opponent’s argument stronger as well, even to the point of conceding some ground to her and coming to a reconciliation, out of which both of us would be reputationally enhanced.
In fact, I have to say I spend quite a bit of time having these imaginary to-and-fros, not only with ‘real people’, but often with TV pundits or politicians who’ll never know of my existence. To take another example, when many years ago I was accused of a heinous crime by a young lad to whom I was a foster-carer, I spent excessive amounts of time arguing my defence against imaginary prosecutors of fiendish trickiness, but the case was actually thrown out without my ever having, or being allowed, to say a word in a court-house, other than ‘not guilty’.
So, is all this just so much wasted energy? Well, of course not. For example, I’ve used all that reflection on the court case to give, from my perspective, a comprehensive account of what happened and why, of my view of the foster-care system and its deficiencies, of the failings of the police in the matter and so forth, to friends and interested parties, as well as in writing on my blog. And it’s the same with all the other conversations with myself – they’ve sharpened my view of the matter in hand, of people’s motivations for holding different views (or my view of their motivations), they’ve caused me to engage in research which has tightened or modified my position, and sometimes to change it altogether.
All of this is preliminary to my response to reading The enigma of reason, by Dan Sperber and Hugo Mercier, which I’m around halfway through. One of the factors they emphasise is this reputational aspect of reason. My work to justify myself in the face of a false allegation was all about restoring or shoring up my reputation, which involved not just explaining why I could not have done what I was accused of doing, but explaining why person x would accuse me of doing it, knowing I would have to contend with ‘where there’s smoke there’s fire’ views that could be put, even if nobody actually put them.
So because we’re concerned, as highly socialised creatures, with our reputations, we engage in a lot of post-hoc reasoning, which is not quite to say post-hoc rationalisation, which we tend to think of as making excuses after the fact (something we do a lot of as well). A major point that Sperber and Mercier are keen to emphasise is that we largely negotiate our way through life via pretty reliable unconscious inferences and intuitions, built up over years of experience, which we only give thought to when they’re challenged or when they fail us in some way. But of course there’s much more to their ‘new theory of human understanding’ than this. In any case much of what the book has to say makes very good sense to me, and I’ll explore this further in future posts.
a discussion on scientific progress and scientism

‘Scientific progress depends on an expectation of continuous innovation, on encouraging an attitude of willingness to experiment, rejecting established authority of every sort, on the assumption that new experiments will bring out new realities and force us to revise our knowledge.’
Bruno Maçães, The Dawn of Eurasia
Discuss ‘scientific progress’ in the light of this statement.
Canto: This is very interesting. As a ‘fan’ (remembering that this word comes from ‘fanatic’) of scientific progress, an evidence junky, and also a humanist, I can see, and have experienced, a collision between the scientific process, which involves a respect for evidence rather than people, and the strongly held cultural/religious beliefs of people, which they hold fast to as identifying and solidifying principles. For example, the Aboriginal belief, handed down and taught, that their people have inhabited this land for eternity, while scientists are trying to determine precisely when the first home sapiens arrived here, and how old the continent of Australia actually is, given the pre-existence of Gondwana, Pangaea and the rest.
Jacinta: A belief probably not held by that many Aboriginal people, most of whom have been educated in institutions that treat science seriously. That’s to say, more recent generations, and this is a problem everywhere – ‘established authority’ can also mean traditional beliefs and practices, even the old established language. The tribal language, the local language, being abandoned everywhere for more global forms of communication.
Canto: Yes I read yesterday an essay topic about the growth of English as an international language, often as a person’s second or third language – and I recognised immediately that the essay was out of date as it stated that about 900,000 used English that way. It’s well over a billion now and rising fast.
Jacinta: And the language of science is largely English – plus mathematics. It’s funny that there are actual scientific endeavours to preserve many of the 7,000 languages that exist in the world, while scientific communication relies largely on a universal single language…
Canto: Yes, and a person can feel that contradiction, that kind of tugging both ways, within themselves. Like following Scottish or Jewish traditions at times of celebration, enjoying the fun, and then thinking – why am I doing this? I don’t believe in first-footing or plate-breaking or whatever.
Jacinta: People follow these traditions because they work, or at least they think so, but not always in the traditional way. And many such followers are well aware of this – that these activities don’t work as lucky charms so much as social glue. But that’s the trouble with glue – you get stuck.
Canto: You’ve heard of the missionary who tried to Christianise the Andaman Islanders and was speared to death for his efforts? Most people’s responses were of the ‘serves him right’ type. But wasn’t that because the missionary was just trying to substitute one set of myths for another? If he was trying to introduce a new fishing method, or, I don’t know, something modernising and scientific…
Jacinta: We’ll have to get onto so-called ‘scientism’ at some stage, but here’s the thing. Maçães writes about ‘rejecting established authority of every sort’, and Richard Feynman apparently described science as belief in the ignorance of experts, but when we come upon, say, the Piripkura people of Brazil’s Mato Grosso, whose continued existence in the face of western diseases and cattle-raising gunmen we’re not even sure about, converting such people into scientific modernists who should question why they’re having difficulty surviving and adapting, seems very arrogant somehow.
Canto: This is where humanism comes in, and it’s a fraught kind of humanism. Many would say – look, all these tribes will disappear, because their way of life is outdated and ‘in the way’, which doesn’t mean the people will disappear, they’ll gradually get absorbed into the broader population, modernised, urbanised, educated and homogenised into our diverse modern world. If they’re lucky enough not to die of disease and gunshot wounds.
Jacinta: And their expertise in traditional hunting, gathering and fishing will be found to be not so much ignorant as obsolete within the mechanised world of food production and consumption. And this is happening everywhere, from the Limi of south-western China to the Bushmen of Botswana. Could it be said that they’re the victims of scientific progress? It’s hard to distinguish science and technology from other aspects of modernism I suppose, but this is the complex other face of science’s otherwise refreshing respect for innovation, experiment and evidence rather than ‘experts’, or just plain old people.
Canto: So what do you think of ‘scientism’, which is I think a rather vague claim about the steamrolling arrogance of science, and what about the possibly self-destructive implications of relentless scientific advancement?
Jacinta: You know there might be something in the criticism, because as I try to get my head around the complexities of, say, electromagnetism, or neurological interactions, I find myself less drawn to some of my earlier loves, literature and the visual arts. I don’t know if that means I’m arrogantly dismissing them, but I do know they’re not engaging me in the old way. I find science more exciting, and maybe that’s dangerous…
Canto: In what way?
Jacinta: Well, the motto of this blog is ‘rise above yourself and grasp the world’, but that kind of engagement – in something so large if not abstract as ‘the world’….
Canto: The world isn’t abstract – it’s everything. Everything found in time and space. It’s absolute reality.
Jacinta: Well maybe, but that engagement in ‘everything’, it rather detaches you from the smaller world of the people around you, and – and yourself. Rising above yourself entails escaping from yourself and you can’t really do that, can you?
Canto: The sciences of biology, neurology, genetics and so forth are the best ways of learning about ourselves. It all comes back to us in the end, doesn’t it? Our mathematical equations, our experiments, our discoveries of black holes, the Higgs boson, gravitational waves, they’re all about us, somehow. The things we do. And it seems it helps our understanding and sympathy. Science is about finding out things, like finding out about other people. The more we find out, the less we tend to dismiss or hate, or fear. Look at those who commit acts of terror. Surely ignorance plays a major role in such acts. A refusal or inability to find out stuff about others. A lack of curiosity about why people are different in the way they look and act. Science – or the scientific impulse, which is basically curiosity – opens us up to these things, so that we no longer hate or fear mosquitos or spiders or snakes or Christians or Moslems or Jews.
Jacinta: Hmmm, so what’s the buzz about scientism? Let’s end this post by discussing a quote from an essay on scientism written for the American Association for the Advancement of Science:
It is one thing to celebrate science for its achievements and remarkable ability to explain a wide variety of phenomena in the natural world. But to claim there is nothing knowable outside the scope of science would be similar to a successful fisherman saying that whatever he can’t catch in his nets does not exist. Once you accept that science is the only source of human knowledge, you have adopted a philosophical position (scientism) that cannot be verified, or falsified, by science itself. It is, in a word, unscientific.
Canto: Well I’m not impressed with this argument, I must say, probably because I don’t agree with the implied definition of science it presents. Science, to me, is an activity, driven by curiosity, which provides dividends in the form of a greater knowledge which raises more and more questions. I rarely worry whether it’s the only source of human knowledge, because that raises the question of what ‘knowledge’ is, and I’m not so interested in that enquiry. Much more interesting to try and work out how life came from non-life, how our planet got covered in water, whether life of any kind exists elsewhere in the solar system, how different parts of the brain interact under particular circumstances, etc etc. I don’t know or care whether you call those enquiries ‘science’ or not, I only know that you won’t get answers to those questions by just sitting around thinking about them. I mean, you can start by thinking, forming a hypothesis, but then you have to explore, gather evidence, conduct experiments, test then modify or abandon your hypothesis…
Jacinta: I thought the ‘net’ analogy used in that quote was pretty inept. Of course it’s reminiscent of the old Kantian categories, the grid or net by means of which we know things, which separates the noumenal world of things in themselves from the phenomenal world of perception/conception. But Kant’s problem was that the noumenal world was just a hypothesis that couldn’t be tested, since we only have our perceptions/conceptions – enhanced somewhat by technology – with which to test things.
Canto: Probably another reason why so many scientists, especially physicists, seem dismissive of philosophers of science. Another problem with those that go on about scientism is that they insist that there are other ways of knowing, but you can rarely pin them down on what those ways of knowing are.
Jacinta: Yes they’re often religious or new-age types, and spiritual knowledge is their stock-in-trade. And if you don’t have that spirituality, which doesn’t need to be explained, then you’ll never understand, you’ll always be a shallow materialist. There’s no response to that view.
Canto: Yes, we’re obviously on the autism spectrum, though not so far along as real scientists. Meanwhile, let’s keep exploring…
another look at free will, with thanks to Robert Sapolsky

Having recently had a brief conversation about free will, I’ve decided to look at the matter again. Fact is, it’s been playing on my mind. I know this is a very old chestnut in philosophy, renewed somewhat by neurologists recently, and I know that far more informed minds than mine have devoted oodles of time and energy to it, but my conversation was with someone with no philosophical or neurological background who simply found the idea of our having no free will, no autonomy, no ‘say’ whatever in our lives, frankly ludicrous. Free will, after all, was what made our lives worth living. It gives us our dignity, our self-respect, our pride in our achievements, our sense of shame or disappointment at having made bad or unworthy decisions. To deny us our free will would deny us…. far far too much.
My previous piece on the matter might be worth a look (having just reread it, it’s not bad), but it seems to me the conundrum can be made clear by thinking in two intuitively obvious but entirely contradictory ways. First, of course we have free will, which we demonstrate with a thousand voluntary decisions made every day – what to wear, what to eat, what to watch, what to read, whether to disagree or hold our tongue, whether to turn right or left in our daily walk, etc etc. Second, of course we don’t have free will – student A can’t learn English as quickly and effectively as student B, no matter how well you teach her; this student has a natural ability to excel at every sport, that one is eternally clumsy and uncoordinated; this girl is shy and withdrawn, that one’s a noisy show-off, etc etc.
The first way of thinking comes largely from self-observation, the second comes largely from observing others (if only others were as free to be like us as we are). And it seems to me that most relationship breakdowns come from 1) not allowing the other to be ‘free’ to be themselves, or 2) not recognising the other’s lack of freedom to change. Take your pick.
So I’ve just read Robert Sapolsky’s take on free will in his book Behave, and it strengthens me in my ‘free will is a myth’ conviction. Sapolsky somewhat mocks the free will advocates with the notion of an uncaused homunculus inside the brain that does the deciding with more or less good sense. The point is that ‘compatibilism’ can’t possibly make sense. How do you sensibly define ‘free will’ within a determinist framework? Is this compatibilism just a product of the eternal complexity of the human brain? We can’t tease out the chain of causal events, therefore free will? So if at some future date we were able to tease out those connections, free will would evaporate? As Sapolsky points out, we are much further along at understanding the parts of the prefrontal cortex and the neuronal pathways into and out of it, and research increases exponentially. Far enough along to realise how extraordinarily far we have to go.
One way of thinking of the absurdity of the self-deciding self is to wonder when this decider evolved. Is it in dogs? Is it in mosquitos? The probable response would be that dogs have a partial or diminished free will, mosquitos much less so, if at all. As if free will was an epiphenomen of complexity. But complexity is just complexity, there seems no point in adding free will to it.
But perhaps we should take a look at the best arguments we can find for compatibilism or any other position that advocates free will. Joachim Krueger presents five arguments on the Psychology Today website, though he’s not convinced by any of them. The second argument relates to consciousness (a fuzzy concept avoided by most neurologists I’ve read) and volition, a tricky concept that Krueger defines as ‘will’ but not free will. Yes, there are decisions we make, which we may weigh up in our minds, to take an overseas holiday or spend a day at the beach, and they are entirely voluntary, not externally coerced – at least to our minds. However, that doesn’t make them free, outside the causal chain. But presumably compatibilists will agree – they are wedded to determinism after all. So they must have to define freedom in a different way. I’ve yet to find any definition that works for the compatibilist.
There’s also a whiff of desperation in trying to connect free will with quantum indeterminacy, as some have done. Having read Life at the edge, by Jim Al-Khalili and Johnjoe McFadden, which examines the possibilities of quantum effects at the biological level, I’m certainly open to the science on this, but I can’t see how it would apply at the macro level of human decision-making. And this macro level is generally far more ‘unconscious’ than we have previously believed, which is another way of saying that, with the growth of neurology (and my previous mention of exponential growth in this field is no exaggeration), the mapping of neurological activity, the research into neurotransmission and general brain chemistry, the concept of ‘consciousness’ has largely been ignored, perhaps because it resembles too much the homunculus that Sapolsky mocks.
As Sapolsky quite urgently points out, this question of free will and individual responsibility is far from being the fun and almost frolicsome philosophical conundrum that some have seemed to suggest. It has major implications for the law, and for crime and punishment. For example, there are legal discussions in the USA, one of the few ‘civilised’ nations that still execute people, as to the IQ level above which you’re smart enough to be executed, and how that IQ is to be measured. This legal and semi-neurological issue affects a significant percentage of those on death row. A significant percentage of the same people have been shown to have damage to the prefrontal cortex. How much damage? How did this affect the commission of the crime? Neurologists may not be able to answer this question today, but future neurologists might.
So, for me, the central issue in the free will debate is the term ‘free’. Let’s look at how Marvin Edwards describes it in his blog post ‘Free will skepticism: an incoherent notion’. I’ve had a bit of a to-and-fro with Marvin – check out the comments section on my previous post on the topic, referenced below. His definition is very basic. For a will, or perhaps I should say a decision, to be free it has to be void of ‘undue influences’. That’s it. And yet he’s an out and out determinist, agreeing that if we could account for all the ‘influences’, or causal operants, affecting a person’s decision, we could perfectly predict that decision in advance. So it is obvious to Marvin that free will and determinism are perfectly compatible.
That’s it, I say again. That’s the entire substance of the argument. It all hangs on this idea of ‘undue influence’, an idea apparently taken from standard philosophical definitions of free will. Presumably a ‘due influence’ is one that comes from ‘the self’ and so is ‘free’. But this is an incoherent notion, to borrow Marvin’s phrase. Again it runs up against Sapolsky’s homunculus, an uncaused decider living inside the brain, aka ‘the self’. Here’s what Sapolsky has to say about the kind of compatibilism Marvin is advocating for, which he (Sapolsky) calls ‘mitigated free will’, a term taken from his colleague Joshua Greene. It’s a long quote, but well worth transcribing, as it captures my own skepticism as exactly as anything I’ve read:
Here’s how I’ve always pictured mitigated free will:
There’s the brain – neurons, synapses, neurotransmitters, receptors, brain-specific transcription factors, epigenetic effects, gene transpositions during neurogenesis. Aspects of brain function can be influenced by someone’s prenatal environment, genes, and hormones, whether their parents were authoritarian or their culture egalitarian, whether they witnessed violence in childhood, when they had breakfast. It’s the whole shebang, all of this book.
And then, separate from that, in a concrete bunker tucked away in the brain, sits a little man (or woman, or agendered individual), a homunculus at a control panel. The homunculus is made of a mixture of nanochips, old vacuum tubes, crinkly ancient parchment, stalactites of your mother’s admonishing voice, streaks of brimstone, rivets made out of gumption. In other words, not squishy biological brain yuck.
And the homunculus sits there controlling behaviour. There are some things outside its purview – seizures blow the homunculus’s fuses, requiring it to reboot the system and check for damaged files. Same with alcohol, Alzheimer’s disease, a severed spinal cord, hypoglycaemic shock.
There are domains where the homunculus and that biology stuff have worked out a détente – for example, biology is usually automatically regulating your respiration, unless you must take a deep breath before singing an aria, in which case the homunculus briefly overrides the automatic pilot.
But other than that, the homunculus makes decisions. Sure, it takes careful note of all the inputs and information from the brain, checks your hormone levels, skims the neurobiology journals, takes it all under advisement, and then, after reflecting and deliberating, decides what you do. A homunculus in your brain, but not of it, operating independently of the material rules of the universe that constitute modern science.
This captures perfectly, to me, the dilemma of those sorts of compatibilists who insist on determinism but. They seem more than reluctant to recognise the implications of that determinist commitment. It’s an amusing description – I love the bit about the aria – But it seems to me just right. As to the implications for our cherished sense of freedom, we can at least reflect that it has ever been thus, and it hasn’t stopped us thriving in our selfish, selfless ways. But as to the implications for those of us less fortunate in the forces that have moved us since childhood and before, that’s another story.

the short life and strange brains of the octopus, and other thoughts

a meeting of minds?
Canto: So we’ve been reading about the strange world of the octopus, and her fellow cephalopods, the squid and the cuttlefish, and what they might tell us about other intelligent forms of life. So what might they?
Jacinta: This is quite a new field of investigation, but certainly an exciting one. The octopus appears to be the most intelligent invertebrate on earth, though we still have lots to learn about it, and we know even less about its cephalopod cousins.
Canto: And we need to be careful about the ‘it’ word, as there are at least 300 species of the beasties, which vary considerably in size, habitat and even quite possibly in life-span.
Jacinta: Yes, some octopuses appear to have very short life-spans, a mere two years, but so little is known about so many of the deeper water species out there…
Canto: They’re predators, of course, feeding mainly on crabs, but some of the shallow-water species are known to scavenge off human activities, stealing bait and the like. They have incredibly flexible, almost amorphous bodies that aren’t co-ordinated simply by a central brain. In fact their nervous systems are still very much a source of mystery.
Jacinta: Like our own. Well, okay we know a helluva lot more about ours. Some other facts: they have three hearts, their eight arms or tentacles are made up of four pairs, they’re all more or less venomous, they’re famously able to match their colour to their surroundings pretty well instantly, they can unscrew the lids of jars to get at the contents, some species collect shells to use as constructions around their homes, they have very high brain-to-body mass ratios, and they appear to be very quick to learn new stuff.
Canto: Apparently tentacles are out, they’re called arms. Tentacles are another thing. A cuttlefish has two tentacles and eight arms. Snails have tentacles. As to the brain and nervous systems of octopuses, here’s what we know. Two thirds of its neurons are to be found in its arms, and they can allow the arms to act independently to some extent. Interestingly, although octopuses have complex motor systems, they don’t have an internalised map of the body as vertebrates apparently do. It’s called a somatotopic map, and it’s found in humans in the primary somatosensory cortex, at the top of the brain. Octopuses’ brains/nervous systems are organised quite differently, and that’s the point – their relationship to us on the evolutionary bush is very distant indeed.
Jacinta: Yes, that’s exactly what makes them fascinating – they’ve evolved a complex nervous system on a completely different plan, like aliens.
Canto: Not quite – they still have neurons after all, and DNA. But the link between humans and octopuses probably goes back at least 500 million years, to some of the earliest complex life forms.
Jacinta: Not so complex by modern standards…
Canto: Indeed, something like a sea worm or sea sponge. Anyway, although they appear to have highly developed intelligence, their learning capacity is really hard to ascertain. They’re not highly social animals like many primates and cetaceans are, and they certainly don’t learn from their parents, since both parents ‘fall apart’ and die shortly after breeding.
Jacinta: They’re quite inventive, even playful, they’ve been observed pushing objects into circular currents and catching them. They also board fishing boats in search of food and find ways of getting out of lab aquariums. Their ability to flatten and elongate or bunch up when required makes them very slippery little suckers, you always have to keep an eye on them.
Canto: Well no doubt researchers will be keen to learn more about their neurology, but this relatively new understanding of their smarts raises questions about their treatment by researchers – not to mention eating them en masse.
Jacinta: Well just sticking with lab treatment, I remember reading in The Lab Rat Chronicles how the rather complacently cruel treatment of lab rats, and all experimental animals, is being questioned more and more, leading to the use of less invasive neurological and other operational approaches..
Canto: Which would in any case be a good thing – the more we can learn without destroying the living thing we’re seeking to learn about, the better, for obvious reasons.
Jacinta: Rats are really smart animals – and just about the most successful animals on the planet – and they certainly feel pain and become depressed, and it’s clear that octopuses do too. In fact some countries have rules against surgical procedures without anaesthetic for octopuses, presumably based on a growing body of knowledge about them.
Canto: They often lose an arm to predators – which by the way they’re able to regrow – and have been observed to favour and tend to damaged or lost arms and other parts, which is a clear sign of ‘feeling’ the damage. But really, the idea that animals don’t feel pain – any animal – has surely had its day.
Jacinta: So what about eating them? I gather that in some parts, eating them live is a thing.
Canto: Well I’ve always been of two minds about this, about eating other animals. And Peter Wohlleben argues for the smartness and the communal life of trees and plants, so that doesn’t leave us with anything to eat at all, if we’re being truly sensitive to others. But there’s no doubt we’re eating too much, we’re destroying the habitats of huge number of species, on land and sea, to feed our growing and increasingly voracious human population. Nobody knows how that’s going to end, though some are hoping, as ever, for technological fixes – artificial meat, ways of creating bumper harvests using less and less land and so forth.
Jacinta: Another whole realm of discussion, but getting back to octopuses, can they tell us anything about consciousness, given their vastly different origin, compared to us?
Canto: Well I don’t want to get into consciousness now – that’s such a massive subject – but they can tell us a lot about a different neurological system, obviously. The fact is, though, that we observe whales, crows, elephants, octopuses, rats and other creatures that are vastly different from each other behaving in ways we, in our indulgent and sometimes condescending manner, consider intelligent, but we know barely anything about, to paraphrase a philosopher, what it’s like to be any of those creatures. Do they have thoughts like us? Or do they have thoughts, but nothing like our own? Which of course raises the question, what exactly is a thought? Can it be reduced to brain processes or do we lose too much in the reduction? Will our endless and increasing probing of human and other brains definitively answer this question?
Jacinta: I think we’ll have to wait till after we die to find out…

Is free will a thing? Apparently not.

Science appears to be cutting the gordian knot of philosophical isms
Canto: The subject of free will often comes up, and I’ve recently read Sam Harris’ booklet on it, so I want to state right now my view that if we do have free will, it’s a far more circumscribed thing than many prefer to believe, and I’m open to the view that it doesn’t exist at all.
Jacinta: Yes I’ve read a fair bit on the subject over the years, including Dennett’s Elbow Room in the eighties, and a collection of essays edited by Bernard Berofsky, dating back to the sixties, but like everyone I’ve forgotten almost all of any book I’ve read within weeks of having read it, so it’ll be good to get back to the subject enfin.
Canto: But have you been exercised by the actual subject, intellectually speaking?
Jacinta: Very much so. Let’s return to our old friend the Dunedin longitudinal study, which indicates that the various personality types – roughly characterised as well-adjusted, confident, reserved, under-controlled and inhibited – are established very early on and rarely change outside of neurological damage. These constrain free will, as does your broad environment, for example whether you’re a scion of the British aristocracy or the offspring of Mongolian goat-herders. You’re not free to choose these things or your genetic inheritance or, presumably, your neuronal wiring, at least not as a youngster.
Canto: I think the free will people would concede all that, but their best argument would be that in spite of all the determining factors that make you who you are, your moment-to-moment decisions – whether to get out of bed or sleep in for a while, whether to break your diet or stick to it, whether to watch a TV program or go to the pub, whether to study physics or psychology at uni (assuming you’re qualified to do either), and so on – these decisions are made of your own volition, so you are responsible for them and nobody else. If there’s no free will, there’s no responsibility, therefore nothing or nobody to praise or blame. And then where would we be with our ethics?
Jacinta: That’s interesting because we often get confused about that, or some people do. I would say most people believe we have free will, so we’re happy to punish people for criminal acts. They chose to commit them after all. But take those serial paedophiles that the tabloid press like to call ‘monsters’. They describe them as incorrigible – that’s to say, uncorrectable. So they should never be released again into the public, once they’ve been proven to commit some heinous paedophile act. What’s being claimed here is that the paedophile can’t help but commit these acts again and again – he has no choice, and presumably had no choice to begin with. But prison is a terrible punishment for someone who has no choice but to be what he is. They’re denying that he has free will, but punishing him for acts that should only be punished if they’re undertaken freely. You can’t have it both ways.
Canto: Well put, and my own tendency towards what used to be called hard determinism comes from reading the writings of ‘compatibilists’ or ‘reconciliationists’ who wanted, I thought, to give themselves as much credit for their success as they possibly could, seeing that they were successful academic philosophers earning, I assumed, the kind of salaries I could only dream of. On the other hand, as a hard determinist, I naturally wanted to blame everyone else, my parents, my working class environment, my lack of wealthy and educated connections, for my abject failures in life.
Jacinta: You jest a little, but I know you’re being essentially serious, in that the Gina Rineharts of the world, inheritors of millions, are the biggest spruikers of the notion that everyone is free to be as rich as everyone else but most people are just too slack, or, for reasons unfathomable to her, aren’t sufficiently interested in material self-enrichment, so they get precisely what they deserve.
Canto: Or what they’re destined to get. Just reading through some of that old philosophical material though, I find myself reliving my impatience with the academicism of philosophy. For example, the endless analysis of ‘able to’, as in ‘she’s able to play the piano’ but she can’t because she hasn’t got one right now. So she has the skill but not, right now, the equipment. Perhaps because she’s fallen on hard times and has had to sell it. Which leads to having ‘potential ability’. She might have been one of the world’s greatest soccer players, having the requisite skill, speed, drive, etc, but she was never introduced to the game or was discouraged from playing it.
Jacinta: She was told to study piano instead. Or more importantly, potential scientific geniuses who just didn’t get the opportunity due to a host of external circumstances, to attain that potential. They say geniuses are made not born, but they require external material to make themselves into geniuses, if that’s what they do. The point is that you can get caught up with words like ‘able to’ or ‘could have done otherwise’, which you can then interpret in varieties of ways, and it becomes almost a philosophy of language thing. But the main point is that although it seems obvious that you can choose between having a piece of cake before bedtime or not, these aren’t the most important choices..
Canto: And maybe even these choices aren’t as freely made as we might think, according to research Sam Harris cites in his essay. It seems science is catching up with what I knew all along. Not only do we have no control whatever over our genetic inheritance, but the way those genes are expressed, based largely on environmental factors, which lead to our brains being wired up in particular ways to release particular levels of hormones and neurotransmitters in patterned ways, leading to those character types identified in the Dunedin study, all of this is way beyond our conscious control. In fact it’s fair to say that the gradual retreat of the notion of free will is largely the result of the assault on the primacy of consciousness. Far more of what we do is less conscious than we think.
Jacinta: Yes the neurophysiological research around everyday ‘decisions’ is compelling, and disturbing to many. It suggests that our feeling of having freely decided on something is a delusion, though perhaps an evolutionarily useful one. Believing in free will usually entails belief in personal moral responsibility, and thus supports punishment for damaging acts and reward for heroic or beneficial ones. And some research has actually shown that people primed to disbelieve in free will are more prepared to cheat and pilfer than those who aren’t.
Canto: So if this continues, this spread of disbelief or skepticism about free will, it may lead to a spike in criminal activity, large and small?
Jacinta: Well I don’t know if there’s been a rise in crime, but there has certainly been a rise in ‘my brain made me do it’ defenses. The effect of all this might be a ‘go with the flow’ attitude to pursue self-interest because your brain’s wiring supposedly impels you to.
Canto: So, that’s interesting, maybe a solution to this is more knowledge. The understanding that we’re the most social mammals on the planet, and that what we do, such as cheating and pilfering, adversely affects others, which will ultimately rebound on us. Even our brain’s own wiring has been caused by environmental factors, primary among those being human factors. So emphasising that our ‘self’ is more of a social self than our privileged access might lead us to believe will encourage us to consider what we owe to the wider society that helped shape us.
Jacinta: Yes, that’s a good point. And I think, as Harris and others point out, jettisoning the free will notion should help us reduce our tendency to blame and hate. I struggle myself with this – I ‘hate’ Trump, but I quickly realise he’s always been like this, and I can’t even blame his parents, who are what they are, etc. So I turn, as I think I should, to a US political system that enables such a person to reach the position he’s reached. In focusing on this system I can heap blame upon blame to my heart’s content, which I always love to do, without getting personal, which may have rebounding consequences for me. It’s a great solution.
Canto: Anyway, I think we’ve just scratched the surface with this one. Don’t we sometimes appear to agonise over decisions? People make lists of pros and cons about whether to spend x money or whether to travel to y, or whether or not to break up with z. How does this sort with a lack of free will? There must be a lot more to say.
Jacinta: It’s determined by our brain’s wiring that we agonise over some of our decisions and not over others. And how often do we make those lists you speak of, often prompted by others, and then just go with our original intuition?
Canto: Hmmm, I still think this is all worth further consideration…
Jacinta: I don’t think there’s any way you can seriously argue for free will. The argument is essentially about the consequences.

what should a vegan’s pet eat, and other immortal questions
Jacinta: So here’s a question – if vegans have pets – say a cat or a dog – do they feed them only vegetables?
Canto: I don’t know, I suppose it would depend on the vegan…
Jacinta: Shouldn’t it depend on the pet? Cats and dogs are carnivores aren’t they? So it would be a form of cruelty to deprive them of meat. Might even be murder.
Canto: We don’t extend murder to the killing of other animals.
Jacinta: Many vegans do.
Canto: Good point. I once read an article by a vegan philosopher, who gets out of those problems by declaring that using animals as pets is unethical. A form of slavery, I suppose.
Jacinta: So, we free the pets? Along with the cows, the sheep, the donkeys, the camels, the water buffalos, the horses, the chooks and pigeons and all those other creatures we’ve used and abused so horridly?
Canto: Well, from memory – I’ll never be able to hunt out the article – he didn’t address the issue of those animals already under captivity of one sort or another. He was simply wanting to argue on general principles that using animals for our personal benefit was unethical.
Jacinta: Even if it benefits the animal?
Canto: Well I suppose the argument would be that even a well-treated slave is still a slave.
Jacinta: But if you free a dog, say, what would happen to it? You’re actually throwing it out of its home, it has nowhere else to go. And I believe that there’s historical evidence that dogs, and probably cats too, have adapted to live with humans. That it was their choice, in a sense. Like pigeons in the city getting fat on leftover bits of hamburger, with no obvious ill-effects. Do pigeons get diabetes?
Canto: Well there’s an obvious difference between scavenging pigeons and pets. Pets don’t choose to become pets. I think that’s the way the argument would run. Unfortunately there are a lot of current pets who would suffer from being set free, but that’s not the issue.
Jacinta: I think I see. We look after the pets we’ve got, then bury them and don’t have any more. And this wouldn’t mean the end of all dogs because there are plenty of strays – scavengers – to maintain the species. And no more enforced ‘pedigree’ breeding – I’d be all for that. But there’s a problem – in order to get rid of all the pets, you have to stop them breeding and that would mean desexing them – a gross interference of their right to reproduce. And if you allow them to reproduce, you must surely bear responsibility for their offspring as your home is theirs. You’re caught in a trap, you can’t walk out, because you love them babies too much.
Canto: You’re looking at it all from a practical perspective, which is all fine and good and relevant, but I think the issue for this philosopher was, I think – judging from him being a vegan – that all such usage of animals – pets as cuddly toys, dolphins as trained performers, horses and camels as pack animals, etc, not to mention farming them for slaughter – is unethical. What do you think of that as a general principle?
Jacinta: I don’t think it holds up, because species take advantage of other species all the time, and not just by preying on them. Sharks have their remoras, we have lice more or less specially adapted to us, roses have their aphids, in fact everywhere you look you have species making use of other species. And presumably being a vegan he marks a strict boundary between animal and vegetable and in reality that’s quite a fuzzy boundary, like with coral. And what about insects, what’s the vegan take on that?
Canto: Presumably negative – they have eyes and antennae and feelings of some sort.
Jacinta: Yes, well it’s a step too far I think. Yes we have a moral responsibility to avoid causing undue suffering….
Canto: Well what about this argument. Because we can survive – and indeed thrive – on only plants, we should do so. I mean, you’re talking about species that, say, are mostly carnivorous – that won’t survive if their food supply dries up. Sharks, for example, they can’t just become vegan, they’ve adapted to a very specific diet. We on the other hand are omnivores, we can dispense with certain varieties of food, including meat, and still live healthy lives, perhaps.
Jacinta: Hmmm, that’s definitely a more difficult question. I do believe that being omnivores, or being very adaptable in our diet has stood us in very good stead in the past, like in the last major ice age when we almost died out apparently. So I’m wondering whether confining our diet might not expose us to greater risks…
Canto: It may not even mean confining our diet – we could synthesise many of the proteins and other nutrients we nowadays get from meat. We’ve already done that, probably.
Jacinta: Well I’ve heard they’re still a long way from synthesising anything that really has the nutrients as well as the texture, flavour, odour and je ne sais quoi of meat. At under about $200, 000.
Canto: And if they achieved that feat, and got it down to competitive prices, would you go vego?
Jacinta: Well of course – I’d have no reason not to. I just don’t think it’ll happen in my lifetime.
Canto: But let’s say for argument’s sake that it does – would you feed this synthetic stuff to your pet cat?
Jacinta: Ah so we come full circle. Yes I would, since it would be more or less chemically identical to meat.
Canto: But animals that have adapted to become carnivores have also adapted to become hunters. They go together. Haven’t you turned your cat from its proper course in life?
Jacinta: No, she became removed from her ‘proper course’, if there is such a thing, by becoming my pet, whether by her choice or mine, or the choice of her ancestors. Likely she will keep up her hunting skills, catching flies and insects and mice and small birds, if she can. And she will benefit from being my friend, as I will benefit from being hers. Like all good friends, we’ll use each other for own purposes, which we hope will be, and will try to make, mutually beneficial.
Canto: Okay, no further questions your excellency.
