on free will and libertarianism 2: character and punishment
I hope I have dispelled two fallacies that have allowed the sciences of human nature to sow unnecessary fear. The first fallacy is that biological explanations corrode responsibility in a way that environmental explanations do not. The second fallacy is that causal explanations (both biological and environmental) corrode responsibility in a way that a belief in an uncaused will or soul does not.
Steven Pinker, ‘the fear of determinism’, from The blank slate
Canto: I’m currently reading Jane Goodall’s book Through a window, about the chimp communities in Tanzania observed and monitored by herself and her team over twenty-odd years – the hierarchies, the friendships, the brutalities, the shifting allegiances and the tragedies. It’s all very recognisable to me, a fellow primate – enough to bring tears to my eyes on occasion.
Jacinta: So we were talking about free will and all that.
Canto: Precisely. We don’t get to choose our species, or our parents, or in the case of chimps, our mothers in particular. Nor do we choose to get crippled by polio, pushed from a high tree-branch, or killed in infancy, for no apparent reason, by an enraged or jealous, or perhaps insane, adult female. Are these environmental or biological events? Does it really matter?
Jacinta: And if we survive them, they shape our character, is that your point?
Canto: Well, I’ve just reread a section of Steven Pinker’s The blank slate, which deals with what he considers our ‘unreasonable fear of determinism’, and it reminds me of what I found so unpalatable about certain academics’ disdain for the idea that determinism diminishes personal responsibility. Pinker, in this essay, reminds me of those typical sons of privilege who mock the ‘his genes/environment made him do it’ legal defence that lawyers sometimes use to get their clients off. I should remind Pinker and his ilk that most individuals who find themselves in legal trouble due to the environment they didn’t choose to grow up in can’t afford lawyers, so they usually don’t get a chance to make those arguments let alone win them. They have to throw themselves on the mercilessness of the court, whose bewigged officers make it clear which class they belong to and and are there to uphold.
Jacinta: So I take it that the above Pinker quote isn’t entirely kosher to you.
Canto: Yes, it’s bullshit. Pinker gives himself away with the examples he chooses to use. He mocks the environmental determinist ‘defence’ without coming remotely close to examining environmental determinism itself (which cannot, by the way, be disentangled from biological determinism, and I don’t find the distinction a particularly valid one). Instead he smugly recites a list of lawyerly tropes – ‘the abuse excuse, the Twinkie defence, black rage, pornography poisoning, societal sickness, media violence, rock lyrics’, etc, without showing a moment’s insight into the kinds of lives I saw around me while growing up, and which have been recounted by those lucky enough to survive, or by those who stood witness to the misery of others.
Jacinta: So your point is that the fallacies Pinker ‘identifies’ in the quote at the top of this post are not fallacies at all?
Canto: Well, my point is that Pinker oversimplifies the issue to a risible degree. Or rather, he doesn’t even address it. For example, he mocks ‘the abuse excuse’, as if abuse is an ‘excuse’ for something rather than a trauma with lifelong effects, depending on its intensity, its type, its duration and other variables including the enormously complex background against which it occurs. These events shape the very being of that person, pig, rat or butterfly. And yet Pinker has the chutzpah to claim that he and his white horse have ridden into view to dispel for us the ‘fallacy’ that such abuse corrodes any responsibility we have for our actions. Yeah, but… nah.
Jacinta: So what about this concept of responsibility? And how we relate it to crime and punishment. Can we really say that we’re not, or never, responsible for our actions?
Canto: I think we’re tricked into thinking we’re responsible by the felt complexity of our own thoughts. When we look at less complex animals – dogs, for example, or birds, we’re much less liable to attribute responsibility to their actions. So what’s the difference between those creatures and ourselves? Surely it’s only complexity.
Jacinta: And the fact that we can speak for ourselves – which is part of our complexity – and other creatures can’t. We can voice the claim that we were free to do otherwise, as no other creature can, as far as we know. But what does all this mean for apportioning blame and punishment? Is our court and justice system obsolete?
Canto: Well the justice system is, I suppose, designed to keep us safe from each other. You see this, again in a less complex way, with wild animals. I recall watching a video of pack animals, I can’t recall, maybe hyenas or wolves, in which the pack leader for some reason started behaving dysfunctionally – that’s to say, to the detriment of the pack. He was biting and wounding other pack members for no apparent reason. Eventually, it got too much, and the pack rose up against him, hurting him badly, and sending him to the back of the pack. From then on he behaved more like the runt of the litter, living off the scraps of the others. You see this sort of thing too, in gorilla and chimp groups. The group deals with the alpha male turned miscreant But if we can only agree on the evidence that free will is a myth, then we should be able to develop a far better justice system than the one we have.
Jacinta: How so?
Canto: Well, take one very toxic issue. Paedophilia. There’s at least one person I know well who has a kind of zero tolerance, ‘worst of the worst’ attitude to serial paedophiles, and simply doesn’t want to hear any kind of free will argument that might ‘exonerate’ them. It’s easy to understand this attitude being held by a victim whose life has been seriously damaged by a paedophile, and as we know, they’re a favourite tabloid newspaper villain. But, as has been pointed out by Sam Harris among others, arguments that paedophiles are the worst of the worst and are incorrigible, ‘never to be released’, are essentially arguments for a lack of free will. If they can never be ‘corrected’, how can they be held responsible for their ‘incorrectness’ in the first place? It follows that ‘punishment’ for such people not only doesn’t work, but is unfair. A justice system should of course be about protecting people from the malpractices of the minority, but surely it needs to be accompanied or tied up with an understanding of how these malpractices arise, and how to fix them.
Jacinta: Do you think serial paedophilia is fixable?
Canto: I have no idea, but I’m saying that should be the aim. To take a simpler example, I don’t know if a broken diff in a car is fixable (I don’t even know what that is), but I don’t see why it wouldn’t be, and if it can be fixed obviously it should be. As Robert Sapolsky points out, we’ve fixed schizophrenia largely with medications, and knowing more than one schizophrenic as I do, that has improved their lives massively.
Jacinta: Okay, so maybe that’s enough about free will for now. There’s another kind of freedom that’s been in the air for decades, and that’s political freedom – freedom from the tyranny of Big Government. It has generally gone by the name ‘libertarianism’. I suppose that if there’s no free will, that kind of freedom doesn’t even get out of the starting gate?
Canto: Well political libertarianism brings up a whole different set of issues, though clearly it’s dependent on and assumes free will. But we’ll leave all that for next time.
20: bonobo and human families, early childhood and free will
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.

Robert Sapolsky, Behave: the biology of humans at our best and worst. 2017
kin selection – some fascinating stuff
Canto: So we’ve done four blogs on Palestine and we’ve barely scratched the surface, but we’re having trouble going forward with that project because, frankly, it’s so depressing and anger-inducing that it’s affecting our well-being.
Jacinta: Yes, an undoubtedly selfish excuse, but we do plan to go on with that project – we’re definitely not abandoning it, and meanwhile we should recommend such books as Tears for Tarshiha by the Palestinian peace activist Olfat Mahmoud, and Goliath by the Jewish American journalist Max Blumenthal, which highlight the sufferings of Palestinian people in diaspora, and the major stresses of trying to exist under zionist monoculturalism. But for now, something completely different, we’re going to delve into the fascinating facts around kin selection, with thanks to Robert Sapolski’s landmark book Behave.
Canto: The term ‘kin selection’ was first used by John Maynard Smith in the early sixties but it was first mooted by Darwin (who got it right about honey bees), and its mathematics were worked out back in the 1930s.
Jacinta: What’s immediately interesting to me is that we humans tend to think we alone know who our kin are, especially our extended or most distant kin, because only we know about aunties, uncles and second and third cousins. We have language and writing and record-keeping, so we can keep track of those things as no other creatures can. But it’s our genes that are the key to kin selection, not our brains.
Canto: Yes, and let’s start with distinguishing between kin selection and group selection, which Sapolsky deals with well. Group selection, popularised in the sixties by the evolutionary biologist V C Wynne-Edwards and by the US TV program Wild Kingdom, which I remember well, was the view that individuals behaved, sometimes or often, for the good of the species rather than for themselves as individuals of that species. However, every case that seemed to illustrate group selection behaviour could easily be interpreted otherwise. Take the case of ‘eusocial’ insects such as ants and bees, where most individuals don’t reproduce. This was seen as a prime case of group selection, where individuals sacrifice themselves for the sake of the highly reproductive queen. However, as evolutionary biologists George Williams and W D Hamilton later showed, eusocial insects have a unique genetic system in which they are all more or less equally ‘kin’, so it’s really another form of kin selection. This eusociality exists in some mammals too, such as mole rats.
Jacinta: The famous primatologist Sarah Hrdy dealt something of a death-blow to group selection in the seventies by observing that male langur monkeys in India commit infanticide with some regularity, and, more importantly, she worked out why. Langurs live in groups with one resident male to a bunch of females, with whom he makes babies. Meanwhile the other males tend to hang around in groups brooding instead of breeding, and infighting. Eventually, one of this male gang feels powerful enough to challenge the resident male. If he wins, he takes over the female group, and their babies. He knows they’re not his, and his time is short before he gets booted out by the next tough guy. Further, the females aren’t ovulating because they’re nursing their kids. The whole aim is to pass on his genes (this is individual rather than kin selection), so his best course of action is to kill the babs, get the females ovulating as quickly as possible, and impregnate them himself.
Canto: Yes, but it gets more complicated, because the females have just as much interest in passing on their genes as the male, and a bird in the hand is worth two in the bush…
Jacinta: Let me see, a babe in your arms is worth a thousand erections?
Canto: More or less precisely. So they fight the male to protect their infants, and can even go into ‘fake’ estrus, and mate with the male, fooling the dumb cluck into thinking he’s a daddy.
Jacinta: And since Hrdy’s work, infanticide of this kind has been documented in well over 100 species, even though it can sometimes threaten the species’ survival, as in the case of mountain gorillas. So much for group selection.
Canto: So now to kin selection. Here are some facts. If you have an identical twin your genome is identical with hers. If you have a full sibling you’re sharing 50% and with a half-sibling 25%. As you can see, the mathematics of genes and relatedness can be widened out to great degrees of complexity. And since this is all about passing on all, or most, or some of your genes, it means that ‘in countless species, whom you co-operate with, compete with, or mate with depends on their degree of relatedness to you’, to quote Sapolsky.
Jacinta: Yes, so here’s a term to introduce and then fairly promptly forget about: allomothering. This is when a mother of a newborn enlists the assistance of another female in the process of child-rearing. It’s a commonplace among primate species, but also occurs in many bird species. The mother herself benefits from an occasional rest, and the allomother, more often than not a younger relation such as the mother’s kid sister, gets to practice mothering.
Canto: So this is part of what is called ‘inclusive fitness’, where, in this case, the kid gets all-day mothering (if of varying quality) the kid sister gets to learn about mothering, thereby increasing her fitness when the time comes, and the mother gets a rest to recharge her batteries for future mothering. It’s hopefully win-win-win.
Jacinta: Yes, there are negatives and positives to altruistic behaviour, but according to Hamilton’s Rule, r.B > C, kin selection favours altruism when the reproductive success of relatives is greater than the cost to the altruistic individual.
Canto: To explain that rule, r equals degree of relatedness between the altruist and the beneficiary (aka coefficient of relatedness), B is the benefit (measured in offspring) to the recipient, and C is the cost to the altruist. What interests me most, though, about this kin stuff, is how other, dumb primates know who is their kin. Sapolsky describes experiments with wild vervet monkeys by Dorothy Cheney and Robert Seyfarth which show that if monkey A behaves badly to monkey B, this will adversely affect B’s behaviour towards A’s relatives, as well as B’s relatives’ behaviour to A, as well as B’s relatives’ behaviour to A’s relatives. How do they all know who those relatives are? Good question. The same researchers proved this recognition by playing a recording of a juvenile distress call to a group of monkeys hanging around. The female monkeys all looked at the mother of the owner of that distress call to see what she would do. And there were other experiments of the sort.
Jacinta: And even when we can’t prove knowledge of kin relations (kin recognition) among the studied animals, we find their actual behaviour tends always to conform to Hamilton’s Rule. Or almost always… In any case there are probably other cues, including odours, which may be unconsciously sensed, which might aid in inclusive fitness and also avoiding inbreeding.
Canto: Yes and It’s interesting how this closeness, this familiarity, breeds contempt in some ways. Among humans too. Well, maybe not contempt but we tend not to be sexually attracted to those we grow up with and, for example, take baths with as kids, whether or not they’re related to us. But I suppose that has nothing to do with kin selection. And yet…
Jacinta: And yet it’s more often than not siblings or kin that we have baths with. As kids. But getting back to odours, we have more detail about that, as described in Sapolski. Place a mouse in an enclosed space, then introduce two other mice, one unrelated to her, another a full sister from another litter, never encountered before. The mouse will hang out with the sister. This is called innate recognition, and it’s due to olfactory signatures. Pheromones. From proteins which come from genes in the major histocompatibility complex (MHC).
Canto: Histowhat?
Jacinta: Okay, you know histology is the study of bodily tissues, so think of the compatibility or otherwise of tissues that come into contact. Immunology. Recognising friend or foe, at the cellular, subcellular level. The MHC, this cluster of genes, kicks off the production of proteins which produce pheromones with a unique odour, and because your relatives have similar MHC genes, they’re treated as friends because they have a similar olfactory signature. Which doesn’t mean the other mouse in the enclosure is treated as a foe. It’s a mouse, after all. But other animals have their own olfactory signatures, and that’s another story.
Canto: And there are other forms of kin recognition. Get this – birds recognise their parents from the songs sung to them before they were hatched. Birds have distinctive songs, passed down from father to son, since its mostly the males that do the singing. And as you get to more complex species, such as primates – though maybe they’re not all as complex as some bird species – there might even be a bit of reasoning involved, or at least consciousness of what’s going on.
Jacinta: So that’s kin selection, but can’t we superior humans rise above that sort of thing? Australians marry Japanese, or have close friendships with Nigerians, at least sometimes.
Canto: Sometimes, and this is the point. Kinship selection is an important factor in shaping behaviour and relations, but it’s one of a multiple of factors, and they all have differential influences in different individuals. It’s just that such influences may go below the level of awareness, and being aware of the factors shaping our behaviour is always the key, if we want to understand ourselves and everyone else, human or non-human.
Jacinta: Good to stop there. As we’ve said, much of our understanding has come from reading Sapolsky’s Behave, because we’re old-fashioned types who still read books, but I’ve just discovered that there’s a whole series of lectures by Sapolsky, about 25, on human behaviour, which employs the same structure as the book (which is clearly based on the lectures), and is available on youtube here. So all that’s highly recommended, and we’ll be watching them.

on luck, and improving environments
I’m in the process of reading Behave, by Robert Sapolsky, a professor of neurology and biology at Stanford University, who has tried in his book to summarise, via the research literature, the seconds, then minutes, then hours, then days, then lifetimes and more, that precede any particular piece of behaviour. It’s a dense but fascinating book, which aligns with, and provides mountains of evidence for, my view that we’re far less in control of ourselves than we think.
It seems we think this because of what might be called conscious awareness of our behaviours and our decisions. This consciousness is something we sometimes mistake for control. It’s interesting that we consider it obvious that we have no control over the size of our nose or the colour of our eyes, but we have more or less complete control of our temper, appetites, desires and ambitions.
Humanistically speaking, this understanding about very limited control needs to have massive implications for our understanding of others. We don’t get to choose our parents, our native country or the immediate environment that most profoundly affects our early life and much of our subsequent behaviour. The flow of hormones and neurotransmitters and their regulation via genetic and epigenetic factors proceed daily, hourly, moment by moment, and all we’re aware of, essentially, is outcomes.
A lot of people, I note, are very uncomfortable about this kind of talk. For example, many of us want to treat each other as ‘equal before the law’. But is one person ever ‘equal’ with another? We know – it’s obvious – that we’re all different. That’s how we distinguish people, by their smiles, their voices, their fingerprints, their DNA. So how can we be different and equal at the same time? Or, to turn things around, how can a legal system operate if everyone is treated as different, unique, a special case?
Well, in a sense, we already do this, with respect to the law. No two bank robberies, or rapes, or murders are the same, and the judiciary must be highly attuned to the differences when applying punishments. Nowadays, and increasingly, the mental state of the offender – particularly at the time of the offence, if that can be ascertained – is considered when sentencing. And this is surely a good thing.
The question here is, considering the exponential growth of our neurophysiological knowledge in the 21st century, and its bearing on our understanding of every kind of negative or positive behaviour we engage in, how can we harness that knowledge to improve outcomes and move from a punitive approach to bad behaviours to something more constructive?
Of course, it’s one thing to identify the release or suppression of glucocorticoids, for example, and its effect on person x’s cognitive faculties, it’s entirely another thing to effect a remedy. And to what effect? To make everyone docile, ‘happy’ and law-abiding? To have another go at eugenics, this time involving far more than just genes?
One of the points constantly hammered home in Sapolsky’s book is the effect of environment on everything that goes on inside us, so that, for example, genes aren’t quite as determinative as we once thought. Here are some key points from his chapter on genes (with apologies about unexplained terms such as epigenetic, transcription and transposons):
a. Genes are not autonomous agents commanding biological events.
b. Instead genes are regulated by the environment, with environment consisting of everything from events inside the cell to the universe.
c. Much of your DNA turns environmental influences into gene transcription, rather than coding for genes themselves; moreover, evolution is heavily about changing regulation of gene transcription, rather than genes themselves.
d. Epigenetics can allow environmental effects to be lifelong, or even multigenerational.
e. And thanks to transposons, neurons contain a mosaic of different genomes.
And genes are only one component of the array of forces that influence or control our behaviour. We know, or course, about how Phineas Gage-type accidents and brain tumours can alter behaviour, but many other effects on the brain can alter our behaviour without us and others knowing too much about it. These include stress, malnutrition, and long-term cultural and religious influences which permanently affect our attitudes to, for example, women, other species and the food we eat. Domestic violence, drug use, political affiliations, educational outcomes and sexual affinities are all more inter-generational than we’re generally prepared to admit.
The first thing we need to do is be aware of all this in our judgment of others, and even of ourselves. There’s just so much luck involved in being who we are. We could’ve been more or less ‘good-looking’ than we are -according to the standards of the culture around us – and this would’ve affected the way we’ve been treated throughout our whole lives. We could’ve been born richer or poorer, with more or less dysfunctional parents, taller or shorter, more or less mentally agile, more or less immune to the pathogens that surround us. On and on and on we could go, even to an extreme degree. We could’ve been born in Algeria, Argentina or Azerbaijan. We could’ve been born in 1912, 1412 or 512, or 150,000 years ago. We could’ve been born a mongoose, a mouse or a mosquito. It’s all luck, whether good or bad is up to us to decide, but probably not worth speculating about as we have no choice but to make the best of what we are.
What we do have is consciousness or awareness of what we are. And with that consciousness we can speculate, as we as a species always have, on how to make the best of ourselves, given that we’re the most socially constructed mammalian species on the planet, and for that reason the most successful, measured by population, spread across the globe, and what we’ve done for ourselves in terms of social evolution – our science, our technology, our laws and our politics.
That’s where humanism comes in, for me. Since we know that ‘there but for the randomness of luck go I’, it surely follows that we should sympathise with those whose luck hasn’t been as lucky as our own, and strive to improve the lot of those less fortunate. Safe havens, educational opportunities, decent wages, human rights, clean environments, social networks – we know what’s required for people to thrive. Yet we focus, I think, too much on punishment. We punish people for trying to improve their family’s situation – or to avoid obliteration – by seeking refuge in safer, richer, healthier places. We punish them for seeking solace in drugs because their circumstances are too overwhelming to deal with. We punish them for momentary and one-off lapses of concentration that have had dire consequences. Of course it has always been thus, and I think we’re improving, though very unevenly across the globe. And the best way to improve is by more knowing. And more understanding of the consequences of that knowledge.
Currently, it seems to me, we’re punishing people too much for doing what impoverished, damaged, desperate people do to survive. It’s understandable, perhaps, in our increasingly individualist world. How dare someone bother me for handouts. It’s not my fault that x has fucked up his life. Bring back capital punishment for paedophiles. People smugglers are the lowest form of human life. Etc etc – mostly from people who don’t have a clue what it’s like to be those people. Because their life is so different, through no fault, or cause, of their own.
So to me the message is clear. Out lives would be better if others’ lives were better – if we could give others the opportunities, the health, the security and the smarts that we have, and if we could have all of those advantages that they have. I suppose that’s kind of impossible, but it’s better than blaming and punishing, and feeling superior. We’re not, we’re just lucky. Ot not.
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.
