On free will and libertarianism 3: freedom and politics

leave a comment »

 

Canto: So I’ve tried to establish my claim that free will just doesn’t exist, which will of course be rejected by those who are obsessed with the notion, who go on at length about freedom from government, the ‘system’, conformism, gender norms, religion, taxation, and so on. Of course, it would be highly unusual to hear any humans asserting their freedom from being human. We all seem to recognise that we’re stuck with that constraint. So, what is it, to be human?

Jacinta: Well I’m not sure if you’ve succeeded in convincing me about a complete lack of free will. It may be a product of complexity – that’s to say, we just don’t know what all the determining factors are, they’re so mind-bogglingly complex that the sense that we’ve made a particular positive or negative decision through the processes of unconstrained thought is probably the best explanation we can make in many circumstances. Isn’t that more or less the compatibilist argument?

Canto: Well, maybe, but I don’t think we’re the best judges of our own decision-making processes, just as, evidence shows, we’re not the best judges of our own abilities, our sex appeal, and so forth. For obvious evolutionary reasons, we’re inclined to think better of ourselves than others think of us. It helps us to keep afloat. But let’s turn now, for a while, to political libertarianism. First, it’s based, it seems to me, on the concept of rights, which is rather recent, though undoubtedly useful in trying to outline for individuals the needed conditions for a fruitful life. 

Jacinta: Inauspicious beginnings, as we’ve discussed before, but perhaps coming of age as a useful guide with the Universal Declaration. But there’s an obvious problem with basing our ethical and political values on individual liberty when we’re clearly the most hypersocial species on the planet. 

Canto: Yes, and that hypersociality has involved the development of somewhat coercive hierarchical state systems such as the feudal system in its various forms throughout Eurasia. These dominance systems, however, have been phenomenally successful for the spread of our species and for our own overall dominance of the biosphere. 

Jacinta: And a domination based on control of land has since morphed into a dominance based on markets. But it’s much more complicated than that. State control has integrated people in terms of language, customs, religion and so forth. As we’ve already pointed out, the food we eat, the clothes we wear, the houses we live in, our jobs, our education, we didn’t create any of these as individuals but acquired them as part of an organisational structure that existed long before we came into being and will continue long after we pass. Isn’t all this rather problematic for libertarians?

Canto: Yes, I’ve pointed out before that libertarianism is really a product of the success of the state system, of hypersocial civilisation. The individual, who is in many respects the product of all this social construction, has been so benefitted by it that she feels she owes it all to her own striving, somewhat like the ungrateful offspring of an all-giving mother. 

Jacinta: Who’s she, the cat’s mother? But it’s interesting that a lot of disadvantaged people, really quite poor people, are stridently anti-government. Look at so many Trumpet types. His buffoonish incompetence predictably led to dysfunction in every sector of government, to the total delight of his supporters. Would you call these people libertarians?

Canto: Well I doubt if they would call themselves libertarians or have much idea of what the term meant, but I’m sure many of them would be in the category of those who rarely or ever vote, who would see, and suffer from, the inequities of society, which are of such a complex nature that one of the easiest targets for their ire would be government. After all, those in government aren’t poor by their standards.

Jacinta: “Don’t vote, it just encourages them”. Yes, these are people without easy connections to big business, higher education, or political clout. Constraints on free will, you might say?

Canto: The politics of resentment, as you realise that particular avenues don’t seem to be open to you, and you might not have even known those avenues existed until it was too late. So these people shouldn’t be labelled as libertarians – their plight is too complex to be pigeon-holed in such a way. The ‘real’ libertarians base their position on the evolution, over the past few centuries, of the concept of rights. They’ve taken the Universal Declaration, based squarely on the individual…

Jacinta: Having at last, in the 20th century, expanded on the ‘man’ part.

Canto: Yes, and they’ve run with it, especially with regard to restraints on individual freedom which affect others, from freedom from taxation to freedom to drive dangerously crappy cars, own hand-guns or go about unmasked and unvaccinated during a pandemic.

Jacinta: Not to mention freedom to exploit others in employment. Doesn’t the USA have about the lowest minimum wage rates in the WEIRD world? Not to mention low rates of what they call ‘unemployment insurance’, which is taxable and of limited duration. “Stop scrounging off the government, get out there and get exploited like us…”

Canto: Yes, we love USA-bashing. But of course libertarianism is far from an exclusively US ideology, anyone can indulge in it. But it does seem to rely heavily on individual freedom as a right, and since free will is a myth, IMHO, that’s a bit of a non-starter. But here I want to talk about rights. I think the Universal Declaration of Human Rights was a great advance, not because of its promotion of rights particularly, but because it was a first attempt to be fully global about the conditions for human flourishing. These conditions will always need to be tweaked, because humanity is evolving. Rights are a useful human construct but we need to be aware of their fundamental artificiality. This artificiality can hopefully be more easily uncovered when we note that they’re based on the individual, an entity that simply doesn’t exist outside of the society or culture that brought it into being. You can, of course, isolate a human being, just as you can isolate a chimp, a bonobo, an elephant, a dolphin or a crow, but you cannot understand or explain or define any of these creatures without understanding the species, sub-species, culture or community they belong to. If we were to talk about the ‘rights’ of a crow, for example, we would have to talk about the conditions required for a crow’s flourishing. And it’s those conditions that really matter, not the crow’s ‘rights’. So ‘rights’ talk is really a way of talking about something else, something much more important. 

Jacinta: So… let me be clear about this. Have you just demolished rights as a fundamental concept?

Canto: Haha, well I’ve just tried to establish, or promote, a more fundamental concept, which goes back in history well before the concept of rights. Aristotle used the term eudaimonia, though whether it was his invention, I don’t know. It doesn’t matter really. Think of it as the conditions for flourishing – whether for a human, a guppy or a tardigrade. They all need their own species to keep on keeping on, as a species. 

Jacinta: Ah, but group selection is a myth isn’t it?

Canto: No, not group selection. The individual, being part of a group, or species, seeks to mate with other members of that species, which is not a sacrifice for the group, far from it. The individual is in some very strong sense motivated to replicate itself through reproduction, which indirectly benefits the species.

Jacinta: So these conditions for flourishing take into account individuals as individual members of something larger, a culture, a species, etc? 

Canto: Yes precisely, that membership of a larger whole, which for humanity has become a more global, hypersocial whole than ever, due to our capacity for destruction – nuclear arsenals, destruction of habitats, greenhouse gas emissions, the production of waste and so forth – makes a mockery of the individual’s claim to freedom of action, when they simply can’t and don’t exist outside of that hypersocial, productive and destructive community. We just need to understand what has made us human, and it’s not what libertarians seem to think it is. And that’s really fundamental. 

Jacinta: Well that’s interesting. Libertarianism really seems to stand and fall on rights, unless there are some types of libertarianism that take a different tack. 

Canto: Yes I’m not really sure if I want to explore the topic any further.

Jacinta: Haha well then that’s all for now.

on free will and libertarianism 1: introducing some issues

leave a comment »

I vaguely remember this book annoying me 35 years ago

Canto: So I’ve wanted to get back to this issue for some time, as it’s been on my mind, to connect an increasingly prevalent political ideology (or so it seems to me) with an increasingly tenuous philosophical position with regard to free will, but I’m not sure whether to start with the politics or the philosophy.

Jacinta: Well I think I can dispose of it all quite quickly. Free will’s a myth and individual freedom, however defined, has gotten us nowhere as a species. That’s it – so it’s off to the pub?

Canto: Well, that might be an interesting starting point, but I think we might need to put some flesh on the bones of those arguments, if I may cannibalise a cliché, or whatever.

Jacinta: Hmmm. So you really think there’s more to say?

Canto: Well I do feel the need to account for my change of position over several decades. Of course I’ve always been a determinist – the whole cause-effect relationship underpins our understanding of all human and non-human behaviour. I don’t think even quantum mechanics disrupts it too much, and to the extent it does, it certainly doesn’t do so in favour of human free will. But way back in the late seventies, when I was first introduced to the topic, ‘hard determinism’ as the term was then, was so out of fashion, and seemed to allow so little wiggle room for our actions, that I kind of assumed it was the province of attention-seeking extremists, or something. And of course it did seem a bit deflating to the human spirit, and all that.

Jacinta: So now you don’t mind a bit of deflation?

Canto: Well, over time, I reflected on my background, and perhaps also on the backgrounds of the philosophers and academics putting forward the compatibilist arguments – that somehow free will is compatible with determinism and even dependent on it. I found this later in Dennett’s book Elbow room, and I think there was some of it in Pinker’s The blank slate too. What I found was a kind of disdainful, and dare I say upper-middle class, attitude to ‘wrong-doers’ who need to be held accountable for their actions. And as a person who grew up in one of the most working-class and disadvantaged suburban regions in Australia, I felt defensive for the people around us (our family were better off than most), their bootlessness and despair. It certainly rubbed off on me in my teen years. I didn’t exactly bear a grudge against the world, but I certainly never had any inspiring teachers or adult figures who encouraged my scintillating intellect.

Jacinta: Okay, enough about you, what about the argument?

Canto: Well let’s look at free will first. The compatibilist argument is that free will is itself a determining factor in the decisions you make. You weigh the pros and cons in your mind, without undue influence from other sources, and determine to have tea with your breakfast instead of coffee, for the first time in months. Of course you’ve done this of your own free will, just as you’ve chosen to feed the dog instead of throwing her out of your 10th storey window, etc etc. The favourite term is ‘you could’ve done otherwise’.

Jacinta: But you didn’t.

Canto: And the feeling that you could’ve done otherwise is also determined, as is the feeling of regret that you quit that job when you should’ve stayed on, that you didn’t make that move interstate, that you didn’t keep in touch with person x, etc. The sense that we could have been better than what we are, could have done better than what we did, these are everyday feelings that we’re never free from. But getting back to compatibilists, they try to have the best of both worlds by claiming that the self is this autonomous determining factor in decision-making. It all revolves around this self. Presumably the developed self, since obviously the two-year-old self is not fully responsible for her actions.

Jacinta: Ah yes and there’s where it all falls apart. Where does this ‘self’ come from? We start as a fertilised egg, the width of a human hair. No brain, no heart, no belly, no skin, just genetic potential. Clearly we’re not making decisions. Nine months later, we’re born, fortunately with all those organs. But surely we’re not making our own decisions at this stage. And we’ve been subjected to a lot in this period, nutrients of all sorts, twists and turns, bumpings and grindings, the sounds of laughter, tears, music, shouts, squeals, long silences, all of which may influence our patterns of neural development both inside and outside the womb. All of which lay down the pattern of our future self, our future ‘free will’.

Canto: Yes, and from that time on its ‘meet the parents’, or caregivers, and/or our siblings and our homes, the furniture of our early lives. Not our choices. I think the no-free-will argument can be most persuasive when you can persuade the opposite side of the most obvious limitations, which are all big ones – for example you don’t get to choose your parents, your place or time of birth/conception, or even the species you were born into. So with those huge limitations accepted, you start to home in on the wiggle room the freewillers have left. Presuming they’re compatibilists, that’s to say determinists, they must accept that all that ultra-connecting and later trimming of neurons in early childhood has nothing to do with personal choice. And yet they try to argue that after all that connecting and trimming, when they’re a ‘fully determined self’, this self goes into auto mode, that of a self-determining self. Which presumably coincides with ‘adulthood’.

Jacinta: Right. As if our courts, or our laws, have solved the free will problem.

Canto: Yes, but it’s a bit like those claims for perpetual motion machines, that can produce output with no energy input. They’re as mythical as free will. The self is essentially only useful as an identifier, and it’s obviously very useful for that. And every self is unique, and perhaps that’s what confuses people. A person can be eccentric, ‘exceptionally different’, in good or bad ways, and we say ‘she’s really her own person’ or ‘she goes her own way’, and strictly speaking that can be said of everyone, whether human, fish or fowl, or of the plants on our balcony, or the jacarandas on our street, each one of which is unique, but not of their own free will.

Jacinta: We mistake complexity for free will, perhaps. Complexity is everywhere on this life-coated planet, but the human brain beats it all for complexity. We carry those things around, we feel it, and so we feel free, to possibly do anything, be anything, learn anything, commit anything. And feel proud when we do the ‘right’ thing, make the requisite effort and so on.

Canto: It’s arguable that this feeling of free will is important for our success. Or our striving. It’s up to you to work hard to pass that exam, to build a successful business, to become a regular in the first team, whatever. The sense of freedom can be exhilarating, though it might be just as obviously caused as the health-giving freedom ‘experienced’ by a plant moved from a nutrient-poor soil to a nutrient-rich one. Something in our environment makes us more successful than the guy down the road, or in Africa, but we don’t want to place too much emphasis on that environment, especially if we know we’ve put in an effort to succeed.

Jacinta: Okay, so what about punishment? As you’ve said, we might claim too much credit for our successes, isn’t a corollary that we place too much blame on those who ‘fail’, who give in to their peers’ world of violence and contempt? Punishment is mostly about deterrence, they say, but isn’t there a better way to treat people than this?

Canto: That’s an interesting question, and of course a complex one. We should talk about it next time.

20: bonobo and human families, early childhood and free will

leave a comment »

ye olde nuclear family, and its enclosures

The bonobo reproduction rate is low, as is ours these days, though for different reasons. Bonobos don’t tend to go all the way, while humans have contraception even for naughty catholics. Muslim scholars seem a little confused about the issue, but are generally more accepting than their catholic counterparts. As to children, humans are rather more possessive about them than bonobos. Bonobo females are largely in charges of the kids, collectively, and paternity is unknown and undisputed. Think about how that would play out in human society, which for millennia has been largely patriarchal, patrilineal and even primogenitive. 

This doesn’t mean male bonobos are hostile to kids, as it’s generally a caring and sharing society, and besides, humouring the kids is a good way of winning favours from their mothers and others. Think of how that would be as a kid – you wouldn’t just be able to run to dad when mum’s mad at you, you’d have any number of adults to run to. You’d also have a range of adults to learn from, to identify with, to consider as role models, as well as to play off against each other. 

Modern, supposedly advanced human society is very different. We live in separate, securitised houses, in nuclear families – ideally mum, dad and 2⅓ kids – with a garden surrounded by a high fence, if we’re ‘lucky’. The grandparents live across town, or in another country, or a nursing home. Visitors are vetted by smartphone. Of course often it’s a single-parent situation, usually mum, and the odd long- or short-lived boyfriend. She works, so the kids spend a lot of time in day-care, meeting other kids and sharing with them one or two adults, who don’t get too close, wary of being accused of funny business. Rarely are these adults male. Still it’s pretty good, lots of toys and games and things to make and do, all in primary colours, but it’s not every day because it’s too expensive, you (the kid) sometimes get shipped around to aunties or friends or assorted baby-sitters, or you get switched to a new centre, with a whole bunch of strangers, or a kid you really like just disappears. But mostly you’re at home with your stupid brother, until school days arrive and you have to wear a uniform, and mum fusses over you and makes you feel nervous and watchful about whether you look different from the other kids, in a good or bad way. And you learn stuff and you like or hate the teacher and you start competing with the other kids and start thinking about how smart or dumb you are. 

Modern human life is pretty regimented. At a certain tender age you go to school where you learn first of all the basics of numeracy and literacy as the first steps toward being civilised. You also learn about rules and regulations, time management and the difference between work and play. Thrown into the school pool of humanity, you’re driven to contemplate and come to terms with variety: fat and skinny, pretty and ugly, noisy and quiet, smart and dumb, friend and enemy and all in between. You learn to make judgments, who to trust, who to avoid, and what to pay attention to. The prefrontal cortex, that amazing human asset, is continuing on its great connective journey, as you negotiate yourself between the formal and the free, between regimentation and independence. 

Yet all the research tells us that most of those judgments you make at school, and which you vaguely remember having made, are actually the product of that growth period before the laying down of memories, distorted or otherwise. And that includes your ability to make effective judgments. 

In the first few years of life, we form more than a million new neural connections every second. In fact, so many that after this surge of connections comes a period of pruning for order and efficiency. But this early period of development requires stimulation, which comes in infinite varieties of ways, including, of course, the bonobo way (and I don’t mean tree-climbing and chomping on insects), the chimp way (watching adult males battling it out), the Tiwi Islander way or the Netherlands royal family way or whatever. And much of this guided stimulation forms our behaviour for the rest of our lives. And the lack of it can reduce our capacities for a lifetime, in spite of subsequent kindness and care, as the notorious case of the Romanian orphans kept in horrendous states of neglect under the Ceauşescu regime has shown, though interestingly, some 20% of those adopted orphans have grown up showing little or no damage. Stimulation can come from within as well as without, and neglect has many variables. 

It stands to reason that we as individuals have little or no control over our development in this crucial period. Which brings me to the issue of free will. Philosophers have traditionally argued for free will on the ‘could have done otherwise’ basis. I could have drunk tea rather than coffee with brekky this morning (though I invariably drink coffee). I could’ve chosen x from the restaurant menu instead of y. So often these trivial examples are given, when it’s screamingly obvious that you don’t get to choose your parents, your genetic inheritance, your early childhood environment, the country or period you were born into, or even the species you were born as (I could’ve snuffed out your brief candle by treading on you in this morning’s walk). Given these restraints on your freedom, restaurant choices surely pale into insignificance. 

But let’s stick with humanity. I won’t go into the neurological underpinnings of the argument against free will (as if I could), but if we treat no free will as a given, then the consequences for humanity, vis-à-vis our handling of crime and punishment, are stark, as  the neurologist and primatologist Robert Sapolsky points out in the penultimate chapter of his book Behave, entitled ‘Biology, the criminal justice system, and (oh, why not?) free will’. This is a vital issue for me, in terms of a more caring and sharing bonoboesque society, so I’ll reserve it for another essay, or two, or more.

progressivism: the no-alternative philosophy

leave a comment »

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.

the self and its brain: free will encore

leave a comment »


yeah, right

so long as, in certain regions, social asphyxia shall be possible – in other words, and from a yet more extended point of view, so long as ignorance and misery remain on earth, books like this cannot be useless.

Victor Hugo, author’s preface to Les Miserables

Listening to the Skeptics’ Guide podcast for the first time in a while, I was excited by the reporting on a discovery of great significance in North Dakota – a gigantic graveyard of prehistoric marine and other life forms precisely at the K-T boundary, some 3000 kms from where the asteroid struck. All indications are that the deaths of these creatures were instantaneous and synchronous, the first evidence of mass death at the K-T boundary. I felt I had to write about it, as a self-learning exercise if nothing else.

But then, as I listened to other reports and talking points in one of SGU’s most stimulating podcasts, I was hooked by something else, which I need to get out of the way first. It was a piece of research about the brain, or how people think about it, in particular when deciding court cases. When Steven Novella raised the ‘spectre’ of ‘my brain made me do it’ arguments, and the threat that this might pose to ‘free will’, I knew I had to respond, as this free will stuff keeps on bugging me. So the death of the dinosaurs will have to wait.

The more I’ve thought about this matter, the more I’ve wondered how people – including my earlier self – could imagine that ‘free will’ is compatible with a determinist universe (leaving aside quantum indeterminacy, which I don’t think is relevant to this issue). The best argument for this compatibility, or at least the one I used to use, is that, yes, every act we perform is determined, but the determining factors are so mind-bogglingly complex that it’s ‘as if’ we have free will, and besides, we’re ‘conscious’, we know what we’re doing, we watch ourselves deciding between one act and another, and so of course we could have done otherwise.

Yet I was never quite comfortable about this, and it was in fact the arguments of compatibilists like Dennett that made me think again. They tended to be very cavalier about ‘criminals’ who might try to get away with their crimes by using a determinist argument – not so much ‘my brain made me do it’ as ‘my background of disadvantage and violence made me do it’. Dennett and other philosophers struck me as irritatingly dismissive of this sort of argument, though their own arguments, which usually boiled down to ‘you can always choose to do otherwise’ seemed a little too pat to me. Dennett, I assumed, was, like most academics, a middle-class silver-spoon type who would never have any difficulty resisting, say, getting involved in an armed robbery, or even stealing sweets from the local deli. Others, many others, including many kids I grew up with, were not exactly of that ilk. And as Robert Sapolsky points out in his book Behave, and as the Dunedin longitudinal study tends very much to confirm, the socio-economic environment of our earliest years is largely, though of course not entirely, determinative.

Let’s just run though some of this. Class is real, and in a general sense it makes a big difference. To simplify, and to recall how ancient the differences are, I’ll just name two classes, the patricians and the plebs (or think upper/lower, over/under, haves/have-nots).

Various studies have shown that, by age five, the more plebby you are (on average):

  • the higher the basal glucocorticoid levels and/or the more reactive the glucocorticoid stress response
  • the thinner the frontal cortex and the lower its metabolism
  • the poorer the frontal function concerning working memory, emotion regulation , impulse control, and executive decision making.

All of this comes from Sapolsky, who cites all the research at the end of his book. I’ll do the same at the end of this post (which doesn’t mean I’ve analysed that research – I’m just a pleb after all. I’m happy to trust Sapolski). He goes on to say this:

moreover , to achieve equivalent frontal regulation, [plebeian] kids must activate more frontal cortex than do [patrician] kids. In addition, childhood poverty impairs maturation of the corpus collosum, a bundle of axonal fibres connecting the two hemispheres and integrating their function. This is so wrong foolishly pick a poor family to be born into, and by kindergarten, the odds of your succeeding at life’s marshmallow tests are already stacked against you.

Behave, pp195-6

Of course, this is just the sort of ‘social asphyxia’ Victor Hugo was at pains to highlight in his great work. You don’t need to be a neurologist to realise all this, but the research helps to hammer it home.

These class differences are also reflected in parenting styles (and of course I’m always talking in general terms here). Pleb parents and ‘developing world’ parents are more concerned to keep their kids alive and protected from the world, while patrician and ‘developed world’ kids are encouraged to explore. The patrician parent is more a teacher and facilitator, the plebeian parent is more like a prison guard. Sapolsky cites research into parenting styles in ‘three tribes’: wealthy and privileged; poorish but honest (blue collar); poor and crime-ridden. The poor neighbourhood’s parents emphasised ‘hard defensive individualism’ – don’t let anyone push you around, be tough. Parenting was authoritarian, as was also the case in the blue-collar neighbourhood, though the style there was characterised as ‘hard offensive individualism’ – you can get ahead if you work hard enough, maybe even graduate into the middle class. Respect for family authority was pushed in both these neighbourhoods. I don’t think I need to elaborate too much on what the patrician parenting (soft individualism) was like – more choice, more stimulation, better health. And of course, ‘real life’ people don’t fit neatly into these categories, there are an infinity of variants, but they’re all determining.

And here’s another quote from Sapolsky on research into gene/environment interactions.

Heritability of various aspects of cognitive development is very high (e.g. around 70% for IQ) in kids from [patrician] families but is only around 10% in [plebeian] kids. Thus patrician-ness allows the full range of genetic influences on cognition to flourish, whereas plebeian settings restrict them. In other words, genes are nearly irrelevant to cognitive development if you’re growing up in awful poverty – poverty’s adverse affects trump the genetics.

Behave, p249

Another example of the huge impact of environment/class, too often underplayed by ivory tower philosophers and the silver-spoon judiciary.

Sapolsky makes some interesting points, always research-based of course, about the broader environment we inhabit. Is the country we live in more communal or more individualistic? Is there high or low income inequality? Generally, cultures with high income inequality have less ‘social capital’, meaning levels of trust, reciprocity and cooperation. Such cultures/countries generally vote less often and join fewer clubs and mutual societies. Research into game-playing, a beloved tool of psychological research, shows that individuals from high inequality/low social capital countries show high levels of bullying and of anti-social punishment (punishing ‘overly’ generous players because they make other players look bad) during economic games. They tend, in fact, to punish the too-generous more than they punish actual cheaters (think Trump).

So the determining factors into who we are and why we make the decisions we do range from the genetic and hormonal to the broadly cultural. A couple have two kids. One just happens to be conventionally good-looking, the other not so much. Many aspects of their lives will be profoundly affected by this simple difference. One screams and cries almost every night for her first twelve months or so, for some reason (and there are reasons), the other is relatively placid over the same period. Again, whatever caused this difference will likely profoundly affect their life trajectories. I could go on ad nauseam about these ‘little’ differences and their lifelong effects, as well as the greater differences of culture, environment, social capital and the like. Our sense of consciousness gives us a feeling of control which is largely illusory.

It’s strange to me that Dr Novella seems troubled by ‘my brain made me do it’, arguments, because in a sense that is the correct, if trivial, argument to ‘justify’ all our actions. Our brains ‘make us’ walk, talk, eat, think and breathe. Brains R Us. And not even brains – octopuses are newly-recognised as problem-solvers and tool-users without even having brains in the usual sense – they have more of a decentralised nervous system, with nine mini-brains somehow co-ordinating when needed. So ‘my brain made me do it’ essentially means ‘I made me do it’, which takes us nowhere. What makes us do things are the factors shaping our brain processes, and they have nothing to do with ‘free will’, this strange, inexplicable phenomenon which supposedly lies outside these complex but powerfully determining factors but is compatible with it. To say that we can do otherwise is just saying – it’s not a proof of anything.

To be fair to Steve Novella and his band of rogues, they accept that this is an enormously complex issue, regarding individual responsibility, crime and punishment, culpability and the like. That’s why the free will issue isn’t just a philosophical game we’re playing. And lack of free will shouldn’t by any means be confused with fatalism. We can change or mitigate the factors that make us who we are in a huge variety of ways. More understanding of the factors that bring out the best in us, and fostering those factors, is what is urgently required.

another look at free will, with thanks to Robert Sapolsky

with 11 comments

Ah poor old Aynnie – from guru to laughing stock within a couple of gens

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.
