a brief and fairly obvious point

leave a comment »


Someone has pointed out that Frump is a bully and a thug. That person witnessed his bullying via the television, as did, presumably, millions of others. The bully, on being named, proceeded to ridicule the person making the point. The invalidity of such a response, a response which has a well-known designation, ad hominem, was shown some 2,500 years ago. It is equally invalid today of course. This invalidity applies equally to all those who say that actors, musicians etc should not be listened to on matters political, or indeed any other matter. A person’s claim must be based on its truth value, not on the person’s profession or supposed expertise.
So it’s of absolutely no relevance whatever whether Frump’s bullying and thuggery is highlighted by an under-rated actor, an over-rated actor, a journalist, an academic or a drunken person in a pub. The only relevant question is whether the claim is true. And it’s a very easy question to answer in this instance ,as the evidence is bigger than your average blue whale.

beyond feminism – towards a female supremacist society

leave a comment »


Canto: I’ves decided to declare myself as a female supremacist.

Jacinta: Really? I thought you had nothing to declare but your genius. So you’ve come out at last?

Canto: Well it’s not as if I’ve been stifled in the closet for years. I’ve rarely thought about it before. I’ve always considered myself a feminist, but recently we’ve been looking at female-male differences, and it’s been making me feel we need more than just equality between the sexes.

Jacinta: You’ve got a hankering for that bonobo world, haven’t you? Females ganging up on you and soothing your aggressive macho emotions with a bit of sexual fourplay.

Canto: Well, yes and no. I first learned about bonobo society almost twenty years ago, and of course it excited me as a model, but then the complexity of human societies with all their cultural overlays made me feel I was naive to imagine a non-human society, without even its own language, could teach us how to improve our own. And the sex stuff in particular – well, that really got me in, but then it seemed too good to hope for. Too much self-serving wishful thinking, to model our society on a bunch of oversexed, indolent banana-eaters.

Jacinta: Do they have bananas in the Congo?

Canto: Absolutely. They have a town there on the Congo River, called Banana.

Jacinta: Oh wow, sounds like heaven. I love bananas. Let’s go there.

Canto: Anyway, now I’m thinking that a female-supremacist society is what we need today, though not necessarily based on bonobos….

Jacinta: That’s disappointing. I think it should be based on bonobos. Bonobos with language and technology and sophisticated theories about life, the universe and everything. Why not?

Canto: Well then they wouldn’t be bonobos. But do you want to hear my reasons for promoting female supremacy?

Jacinta: I probably know them already. Look at the male supremacist societies and cultures in the world – in Africa, in India, in the Middle East. They’re the most violent and brutish societies. We can’t compare them to female supremacist societies because there aren’t any, but we can look at societies where discrimination against women is least rampant, and those are today’s most advanced societies. It might follow that they’ll become even more enlightened and advanced if the percentage of female leaders, in business, politics and science, rises from whatever it is today – say 10% – to, say 90%.

Canto: Yes, well you’re pretty much on the money. It’s not just broader societies, it’s workplaces, it’s schools, it’s corporations. The more women are involved, especially in leadership roles, the more collaborative these places become. Of course I don’t deny female violence, in schools and at home, against children and partners and in many other situations, but on average in every society and every situation women are less violent and aggressive than men. In fact, all the evidence points to a female-supremacist society being an obvious solution for a future that needs to be more co-operative and nurturing.

Jacinta: So how are you going to bring about the female-supremacist revolution?

Canto: Not revolution, that’s just macho wankery. I’m talking about social evolution, and it’s already happening, though of course I’d like to see it speeded up. We’ll look at how things are changing and what we can hope for in some later posts. But the signs are good. The feminisation of our societies must continue, on a global level!

ten negatory claims about same-sex marriage

leave a comment »


percentages of those favouring same-sex marriage (in the US) over twenty-odd years – one of the fastest changes in public opinion in human history

What are the arguments against same-sex marriage? That’s a question I’m asking myself as I hear that conservatives want public money to run a campaign against it if Australia holds a plebiscite – which I’m not particularly in favour of, but at least it makes me reconsider the ‘no’ arguments. Presumably they’d be along the same lines as those of the TFP (tradition, family, property) organisation of the USA, but Australia as a nation is less religiously fixated than the USA, so the weak arguments found on the TFP website would seem even weaker to people over here. But let’s run through their 10 arguments just for fun. You can read them in full on the website if you’ve nothing better to do.

1. It is not marriage.

The claim here is that you can’t just redefine marriage to suit changing situations. ‘Marriage has always been x’, (x usually being identified as a ‘covenant between a man, a woman and god’ or some such thing). The response is, we can and always have done. Marriage is a human invention, and like all inventions we can modify it to suit our needs. A table is a human invention, and it can be a chess table, a bedside table, a coffee table, a dining table or a conference table, and none of these uses threatens the meaning of the word ‘table’. Marriage is ours to define and use as we wish, and historically we’ve done just that, with polygynous marriages, which have been commonplace, polyandrous marriages (much rarer) and other more or less formal arrangements, such as handfasting and morganatic and common-law marriages. Of course, marriage has rarely been recognised between individuals of the same sex, though same-sex unions, some of them highly ritualised and contractualised, have had a long history. But the reason for this is obvious – throughout history, homosexuals have been tortured and executed for their feelings and practices. The history of exclusive male-female marriage coincides with the history of homosexual persecution. The two histories are not unrelated, they’re completely entwined.

2. It violates natural law.

WTF is natural law, you might ask. A TFP fiction apparently. Their website says: Being rooted in human nature, it [natural law] is universal and immutable. But human nature is neither of these things. It’s diverse and evolving, socially as well as genetically. Marriage and child-rearing arrangements vary massively around the globe, with varying results, but it seems clear from voluminous research that children benefit most from close bonding with one or two significant others, together with a wider circle of potential carers and mentors. It’s notable that when this organisation lays down the ‘law’ on matters of marriage, sexuality and families it cites no scientific research of any kind – its only quotes are from the Bible.

3. It always denies children either a father and a mother.

Leaving aside the fact that there are often no children involved, this argument relies on the assumption that a father and a mother are indispensable to the proper rearing of children. Research reported on in Science Daily found that ‘children raised by two same-gender parents do as well on average as children raised by two different-gender parents. This is obviously inconsistent with the widespread claim that children must be raised by a mother and a father to do well’.  Melvin Konner in his 2015 book Women after all puts it this way: ‘One of the most impressive discoveries of the last decade in child development research is that when babies of either sex are adopted by lesbian or gay couples – and this has been studied very extensively and carefully – the main way the resulting children differ from controls raised with a father and mother is that they turn out to be less homophobic.’ Of course, this is exactly what organisations like TFP are afraid of, as promotion of homophobia is what they’re all about.

4. It Validates and Promotes the Homosexual Lifestyle

And that’s precisely what it aims to do. Of course TFP argues, or rather states without argument, that this would ‘weaken public morality’. Humanists would argue precisely the opposite, that such validation is long overdue, and would strengthen a morality based on the recognition of the fundamental humanity and value of diverse individuals.

5. It Turns a Moral Wrong into a Civil Right

In its discussion of this reason to oppose same-sex marriage, TFP again refers to its bogus ‘natural law’. Same-sex marriage (always in inverted commas on its website ) is opposed to nature, according to TFP. Again this is stated rather than argued, but as I’ve often pointed out, bonobos, our closest living relatives, engage in homosexual acts on a regular basis. Of course, they don’t marry, because marriage isn’t natural, it’s a human construction, and mostly a quite usefiul one, though not necessary for child-rearing, or for permanent monogamous relationships. Further to this, researchers have observed homosexual acts in between 500 and 1500 non-human species, so it seems to be natural enough.

6. It Does Not Create a Family but a Naturally Sterile Union

Again TFP makes ad nauseum use of the word ‘nature’ to give credit to its views. But the fact that same-sex couples can’t have offspring without outside help isn’t a reason to debar them from a union that serves multiple purposes. Moreover, it’s quite reasonable for homosexual males or females to feel that they would make good parents, and to yearn to be parents, and there is no reason why this should yearning should be opposed, if the opportunity to parent a child arises. Adopted children are often brought up in loving and happy environments, and succeed accordingly.

7. It Defeats the State’s Purpose of Benefiting Marriage. 

It’s hardly for the TFP or any other organisation to tell us what the State’s purpose is regarding marriage. Most advanced states provide benefits for children, regardless of the marital status of the mother. This is very important, considering the large number of single-parent (mostly female) families we have today. The state also doesn’t distinguish between marriage and de facto relationships when it dispenses benefits. The TFP is obviously out of date on this one.

8. It Imposes Its Acceptance on All Society

States are legalising same-sex marriage around the western world under public pressure. Here in Australia, where same-sex marriage hasn’t yet been legalised, polls have indicated that same-sex marriage is clearly acceptable to the majority. Where it is up to courts to decide, as occurred recently in the USA, the process is too complex to cover here, but it’s clear that the public’s attitude to same-sex marriage in every advanced or developed nation has undergone a seismic shift in a relatively short period – the last ten years or so.

9. It Is the Cutting Edge of the Sexual Revolution

Vive la révolution. Of course, TFP presents the slippery slope argument – paedophilia, bestiality and the like – so hurtful and offensive to the LGBT community. Again, there’s never any presentation of evidence or research, every proposition is presented as self-evident. It’s a profoundly anti-intellectual document.

10. It Offends God

This is, of course, presented as the main argument. Biblical quotes are given, including one in which their god’s mass immolation of ‘sodomites’ is celebrated. I don’t really see much point in questioning the supposedly offended feelings of a supposedly all-perfect, all-powerful invisible undetectable being. It’s all a fairly nasty fantasy.

There’s nothing more to say, and as an intellectual exercise this was probably a waste of time, as people who believe the above guff aren’t listening much. Any critical responses to their 10 propositions on the TFP website will be promptly deleted. There’s definitely no fun to be had with these guys. Their absolute certainty, and their inability and unwillingness to argue cogently or to examine evidence is a very disturbing sign, and a clear indication that they’re fuelled entirely by emotion. A passionate fear of change and difference. It all tends to reinforce the arguments against holding a plebiscite, in which, in Australia, people of this sort would actually be funded to give voice to their certainties with all the indignation of righteousness. They would be ruthless about their targets, and being patriarchal  – because preserving extreme patriarchy is what this is all about at base – they would be violent in their language and tactics. The best way to muzzle them would be to resolve this in parliament as soon as possible.

the greatest country on Earth?

leave a comment »

let's call bullshit

let’s call bullshit

Canto: So Michelle Obama thinks America is the greatest country on Earth…

Jacinta: Not just thinks, but tearfully feels, in every cell of her body, but you know, even she must realise it’s all rhetorical baloney.

Canto: I prefer to call it balderdash – less American.

Jacinta: But you can’t blame pollies for getting all jingoistic come election time, can you?

Canto: I do. I can’t stand it at any time. But I want us to reflect for a while on the meaning of ‘the greatest country on Earth’. Is greatness measurable? Is there currently a fifteenth greatest country on Earth? What are the measuring criteria?

Jacinta: I think you’re taking it all too seriously, but it’s interesting – we’ve observed this before – that every nation in history that has had economic and military superiority over others has assumed this entailed moral superiority. Whereas in the world of realpolitik it just means they’re an apex predator.

Canto: I’m sure Donald Frump would agree, though I think he’s wrong to claim that the USA is no longer an apex predator. There can be room for more than one at the top, though it wouldn’t do to let that space get too crowded.

Jacinta: Yes, so ‘greatest’ can only mean ‘most powerful’, it’s not the kind of term you use to measure a nation’s quality for its own citizens.

Canto: But why are Americans so keen to trumpet their nation’s superiority? I mean methinks they do protest too much.

Jacinta: Well a couple of centuries ago, when the Brits had the strongest economy, weren’t they the same?

Canto: Well, not really… I mean, that wouldn’t be British, would it? I mean they thought they were morally superior of course, but they weren’t so utterly boorish as to proclaim it while banging their tits.

Jacinta: Well you’re making a good point. When imperialist nations or superpowers or whatever start believing they’re better than others in some moral way, they may act accordingly, pushing their weight around, hectoring, lecturing, even taking it upon themselves to punish other nations for not being like them.

Canto: Or invading other nations to show them how ‘being great’ is done. So that’s why we need correctives. We need more objective measures, not for measuring national greatness, which is just a term of power, or just rhetoric, but for measuring success in terms of the well-being, happiness, freedom or whatever of the members of that nation.

Jacinta: I think that people like Obama, and so many Americans, really believe in this rhetoric though. They take a term like ‘great’, and they really think it refers to all those other things – opportunity, well-being, smarts, etc.

Canto: Which is why reality checks are in order. Take the ‘land of opportunity’ rhetoric. What this refers to is social mobility. Anyone has the chance to be anything. But there are surely ways to measure social mobility, which are more or less objective.

Jacinta: Certainly more objective than just making the claim. And it’s interesting, we’ve looked at a few national surveys, based on various criteria, and I can’t recall the USA ever coming in the top ten in any of them. Usually it’s well down the list.

Canto: So it’s time to revisit those surveys. First the OECD survey that was posted on in the past, its better life index. The Organisation of Economic Co-operation and Development (OECD)…

Jacinta: Such a positive, feel-good internationalist title.

Canto: Isn’t it? It was founded in 1948, another of those positives to come out of the negativity of warfare. It’s headquartered in Paris, it has 35 member countries and its purpose is pretty well self-explanatory.

Jacinta: Yes, but while its focus is obviously on economics, primarily, the better life index is a kind of side project, which is almost saying ‘money ain’t everything’, there are all these other factors as well as the economic, to consider when striving for a better life, and a better country.

Canto: Yes they consider 11 factors in all: housing, income, jobs, community, education, environment, civic engagement, health, life satisfaction, safety, and work-life balance. People can give different weightings to these factors, and on their website they allow you to change the weightings so that you’ll come up with a different top ten or twenty of the 35 participating countries.

Jacinta: But according to the weightings they favour, the USA comes a fairly creditable ninth behind Norway, Australia, Denmark, Switzerland, Canada, Sweden, New Zealand and Finland, in that order. But since we’re in Australia we can surely permit ourselves some eye-rolling at your standard Yank jingoism.

Canto: Surely but of course many will say that these ‘objective’ assessment criteria are highly suspect, and possibly anti-American.

Jacinta: Naturally, and we haven’t the resources or the time to evaluate them, so instead we’ll look at a number of these surveys with the assumption that they’re not all anti-American, to see how our chauvinistic allies fare. But it’s interesting that the OECD survey doesn’t highly rate any of the non-Scandinavian European counties. A Scandinavian bias perhaps?

Canto: Well here’s another rather different international survey, which looks instead at cities.

Jacinta: Very relevant considering the world’s rapid urbanisation shift.

Canto: The Mercer Quality of Living rankings looks at living conditions in hundreds of cities ‘according to 39 factors, grouped in 10 categories’: Political and social environment, Economic environment, Medical and health considerations, Schools and education, Public services and transportation, Recreation, Consumer goods, Housing, and Natural environment. And again, you may want to believe its findings are biased and you may be right, but its highest ranking American city is Honolulu at number 31.

Jacinta: Honolulu? Hardly the heart of America.

Canto: Compare neighbouring Canada, which has 5 cities in front of Honolulu. Vancouver (4), Ottawa (14), Toronto (16), Montreal (21) and Calgary (28). Australia and New Zealand also rate far better than the USA with Aukland ranked at 4 (tied with Vancouver), Sydney ranked 10, Wellington 12, Melbourne 18, Perth 21 and Canberra 26. Some 16 European cities are in the top 25, with Vienna being ranked the number one city for the past 6 years in a row. There are no Asian, African or South American cities in the top rankings.

Jacinta: Mercer, by the way, is a human resources consulting firm headquartered in New York, and it’s really hard to get full data from it because it restricts full access to ‘professionals’, presumably behind a paywall. Nosy impoverished amateurs like us are unwelcome. So most of the data we’re using is from back in 2010 (and that’s only from press releases, with little detail) but I doubt that the USA has become any ‘greater’ since then. So it’s clear that the USA is no great shakes, city-wise – in fact it would be classed as probably the lowest-ranked western country in the world, according to this survey…

Canto: Conducted by a New York based firm…

Jacinta: Insofar as the liveability of it’s cities are concerned. And that’s where most people live, after all.

Canto: So it’s not looking good for the bad old USA. Any more surveys?

Jacinta: And in case people quibble about the term ‘western’, let’s be a little more precise. The USA, in terms of the quality of its cities for their own residents, lags behind Western Europe, Australia, New Zealand and Canada.

Canto: That way greatness tells lies.

Jacinta:  There’s a website called numbeo which claims to provide ‘the world’s largest database of user contributed data about cities and countries worldwide. Numbeo provides current and timely information on world living conditions including cost of living, housing indicators, health care, traffic, crime and pollution.‘ Its ‘quality of life index’, based on countries,  looks somewhat similar to that of the OECD, with the USA ranked tenth, well below Australia and New Zealand, ranked third and fourth respectively. However it differs from the OECD in that it ranks a number of non-Scandinavian European countries above the USA, namely Germany, Austria, Switzerland and Spain. And it ranks Canada below the USA, which is unusual. And again the top rankings are dominated by western countries, with Japan being the top Asian country at 16.

Canto: I’ve never heard of numbeo, what are their bonafides and how do they gather data?

Jacinta: It’s a crowd-sourcing site, founded in 2009 by one Mladan Adamovic, a former Google software engineer. It’s evolving, and its findings suggest it’s not particularly an outlier, though at this stage not perhaps as reliable as the OECD.

Canto: Well, with crowd-sourcing, there would be some nation-participants where information would be scarce, or virtually non-existent.

Jacinta: That’s right, but all of these survey organisations and websites face the same problems, and it’s pretty likely that the places from which info is scarce wouldn’t be in the top rankings in any case. If you know your country’s doing well, you’d want to share it.

Canto: Okay, so we’ve looked at three sources. One more?

Jacinta: Yeah well a few more, which I’ll summarise. Monocle magazine, a British lifestyle magazine, has been doing an annual quality of life index based on cities since 2006. Its criteria are ‘safety/crime, international connectivity, climate/sunshine, quality of architecture, public transport, tolerance, environmental issues and access to nature, urban design, business conditions, pro-active policy developments and medical care’, and it ranks Tokyo at number one, whereas Mercer ranked it 44th! It did rank Vienna at number two, however. And it ranked Melbourne at 4 and Sydney at 5, so it must be very objective.

Canto: And the US?

Jacinta: Its highest ranking city was Portland Oregon at 25. So there’s definitely a pattern emerging.

Canto: Where’s Adelaide?

Jacinta: They’ve never heard of it. Another survey based on cities comes from the Economist Intelligence Unit (EIU), from the London-based group that publishes The Economist. They go into a lot of detail about their criteria on their website, so I won’t go into it here. I only had access to their current top 10. It shows Hong Kong at number one, and Sydney at 5. No US cities make the ten, and Vienna isn’t there either. Tokyo comes in at 10. It should be added that they seem to have drastically amended their criteria recently – before that, Vienna regularly came in at number 3, with Melbourne and Vancouver also in the top 5 regularly. Melbourne ranked number 1 in 2011.

Docklands in the Great City of Melbourne

Docklands in the Great City of Melbourne

Canto: That’s interesting about Hong Kong, because I read elsewhere that life expectancy of its residents is about the highest in the world. So the city must be doing something right.

Jacinta: Well I’m sure the Chinese government will put a stop to that.

Canto: Okay I think we’ve done enough survey of surveys – let’s summarise. We started with Michele Obama, in typical US pollie style, proclaiming the greatness of her country.

Jacinta: I.e. not just great but ‘the greatest on Earth’. So we had a look at a handful of the most well-known global surveys of nations and cities, based essentially on liveability criteria. Though it’s impossible to be entirely objective in these surveys, they collectively present a pattern. In none of them did the USA distinguish itself, and in terms of its cities it really did quite badly, as a western nation. As to why that might be the case, we leave that for the reader’s speculations, for now. The gap between US perceptions and reality, I would contend, is largely caused by the assumption that if you’re globally dominant in economic terms, you’re in a ‘great’ country in any or every other way.

Canto: Roman economic hegemony, in the old days, was largely based on a substantial slave population, wasn’t it?

Jacinta: Well, that and being able to dictate terms of trade with others, as every dominant nation or empire has been able to do. But you’re right, a lot of economic success in the past has involved the exploitation of a populous underclass. The USA is by far the most populous of the traditional western countries, and it effectively has no minimum wage. That’s very handy for the McDonald Frumps of that great nation.

why are our brains shrinking?

leave a comment »

my own brain, squeezed of alcohol

my own brain, squeezed of alcohol

Jacinta: So you know that the average human brain mass, or is it volume, has reduced by  – is it 15%, I can’t remember – over the past 20,000 years or so, right? And there’s this theory that it’s somehow related to domestication, because the same thing has happened to domesticated animals…

Canto: How so..?

Jacinta: Well, we don’t know how so, we just know it’s happened.

Canto: How do we know this? Who says?

Jacinta: Well I’ve heard about it from a few sources but most recently from Bruce Hood, the well-known psychologist and skeptic who was talking on the SGU about a recent book of his, The Domesticated Brain. 

Canto: So the idea is that humans have somehow domesticated themselves, in the same way that they’ve domesticated other species, with a corresponding decrease in brain mass in all these species, which signifies – what?

Jacinta: Well it raises questions, dunnit? What’s going on?

Canto: It doesn’t signify dumbing down though – I read in Pinker’s big book about our better angels that our average IQ is rising in quite regular and exemplary fashion.

Jacinta: Yes, the Flynn effect. Though of course what IQ measures has always been controversial. And they do reckon size isn’t the main thing. I mean look at all those small critters that display so many smarts. For example, rats, octopuses and corvids (that’s to say crows, ravens and some magpies). They all seem to be fast learners, within their limited spheres, and very adaptable. But getting back to the human brain, it seems to be something known mainly to palaeontologists, who have a variety of theories about it, including the ‘we’re getting dumber’ theory, but I’m not convinced by that one. It seems more likely that our brains are getting more organised, requiring less mass.

Canto: So this has happened only in the last 20,000 years?

Jacinta: Or perhaps even less – between 10 and 20 thousand.

Canto: Isn’t that a phenomenally short time for such a substantial change?

Jacinta: I really don’t know. They say it might be partly related to a decrease in overall body size, so that the brain to body ratio remains much the same.

Canto: A decrease in body size? What about the obesity epidemic? And I remember way back when I was a kid reading about how we’d been getting taller with each generation since the Great Depression – or was it the Industrial Revolution? Anyway our improved diet, our era of relative abundance, has led to a change in height, and presumably in mass, in only a few generations.

Jacinta: So now you’re saying that substantial changes can occur in a few generations, let alone 10,000 years?

Canto: Uhhh, yeah, okay, but I wasn’t talking about brain size.

Jacinta: Well why not brain size? Anyway, although there have been those recent changes, at least in the west, the story goes that the planet has warmed since the last ice age, favouring less bulky bodies, less fat storage, more gracile frames.

Canto: So what about domestication, why has this led to decreased brain sizes?

Jacinta: Well this is very complex of course…

Canto: I can think of a reason, though it might not be called domestication, more like socialisation, and outsourcing. You can see it in very recent times, with smart phones – it’s even become an already-stale joke, you know phones are getting smarter so we’re getting dumber. But then we always tend to exaggerate the short-term and the present against the longer view. And yet…. I was on the tram the other night, sitting across from this couple, locked into their phone screens, I mean really locked in, earplugs attached, heads bent, utterly fixated on their little screens, completely oblivious, of each other as well as of the outside world. I was reading a book myself, but I became distracted by my irritation with these characters, while wondering why I should be irritated. It just went on so long, this locked-in state. I leaned forward. I waved my hand in front of their bowed heads. I wanted to tell them that the tram had rattled past all the stations and was heading out to sea…

Jacinta: There are some problems with the whole argument. How do we know that domesticated animals have smaller brains? Domesticated cats have a wide range of brain sizes no doubt, but what wild cats are you comparing them with? Even more so with dogs and their immense varieties. Okay they’re descended from wolves so you compare a wolf brain with its modern doggy-wolfy counterpart, but who’s going to agree on type specimens?

Canto: So you brought the subject up just to dismiss it as a load of rubbish?

Jacinta: Well if we shelve the domestication hypothesis for the moment – I’m not dismissing it entirely – we might consider other reasons why human brains are shrinking – if they are.

Canto: So you’re not convinced that they are?

Jacinta: Well let’s be sceptical until we find some solid evidence. In this Scientific American site, from November 2014, palaeontologist Chris Stringer states that ‘skeletal evidence from every inhabited continent’ suggests – only suggests – that our brains have become smaller in the past 10 to 20 thousand years. No references are given, but the article assumes this is a fact. This piece from Discovery channel or something, which dates back to 2010, relies in part on the work of another palaeontologist, John Hawks, whose website we link to here. Hawks also talks about a bucketload of evidence, but again no references. The original research papers would likely be behind a paywall anyway, and barely intelligible to my dilettante brain….

Canto: Your diminishing brain.

Jacinta: Okay I’m prepared to believe Hawks about our incredible shrinking brains, but is domestication the cause, and what exactly is domestication anyway? Hawks doesn’t go with the domestication hypothesis. In fact the Discovery article usefully covers a number of alternative hypotheses, and of course the shrinking may be due to a combo. In fact that’s more than likely.

Canto: So what’s Hawks’ hypothesis, since we’re supposedly admirers of his?

Jacinta: Well Hawks decided to look more closely at this brain contraction – which is interesting because I was thinking along the same lines as he was, i.e. has it been a uniform contraction, or was there a sudden, quick development, followed by a stagnant period, as you would expect?

Canto: Anyway isn’t brain organisation more important than brain mass? Sorry to interrupt, but haven’t we already established that?

Jacinta: We haven’t established anything, we’re just effing dilettantes remember. Hawks started looking at more recent data, over the past 4000 years or so, to see if he could detect any difference in the encephalisation quotient (EQ) – the ratio of brain volume to body mass – over that time. He found that indeed there has. The picture is complicated, but overall there has been a reduction in the brain compared to the body. His explanation for this though is quite different. He reckons that a series of mutations over recent history have resulted in the brain producing more out of less…

Canto: Right, just as a series of modifications have allowed us to produce smaller but more powerful and fuel-efficient cars.

Jacinta: Uhh, yeah, something like that.

Canto: But we know what those modifications were, we can name them. Can we name the mutations?

Jacinta: Clever question, but we know about cars, we built them and they’ve only been around for a bit more than a century. We know vastly less about the brain and we’re still getting our heads around natural selection, give us a break. Hawks points out that it’s a rule about population genetics well-known in principle to Darwin, that the larger the population the more numerous the mutations, and there was a surge in the human population back when agriculture was developed and large settlements began to form. So a number of brain-related mutations led to streamlining and, as you suggest, fuel efficiency.

Canto: But isn’t this compatible with the domestication hypothesis? I imagine that, if there really is a brain reduction for domesticated animals, it’s because they don’t have to rely on their brains so much for survival, and we don’t either, the collective has sort of magically taken care of it through farming and infrastructure and supermarkets.

Jacinta: Yes but they all have their own complicated networks and issues we have to wrap our brains around. The domestication hypothesis is really about aggression apparently. The argument goes that all animals under domestication become more varied in size, coloration and general build, with a tendency to become more gracile over all. Selection against aggression, according to the primatologist Richard Wrangham, favours a slowly developing brain – one that is, in a sense, in a perpetually juvenile state (think of cute cat and dog videos). Of course, all this assumes that juvenile brains are less aggressive than adult brains, which some might see as a dubious assumption.

Canto: Yes, think of school bullying, Lord of the Flies, youth gangs, the adolescent tendency to extremes…

Jacinta: Well, both Wrangham and Hood offer a particularly interesting example of ‘super-fast’ domestication to illustrate their hypothesis:

In 1958 the Russian geneticist Dmitri Belyaev started raising silver foxes in captivity, initially selecting to breed only the animals that were the slowest to snarl when a human approached their cage. After about 12 generations, the animals evidenced the first appearance of physical traits associated with domestication, notably a white patch on the forehead. Their tameness increased over time, and a few generations later they were much more like domesticated dogs. They had developed smaller skeletons, white spots on their fur, floppy ears, and curlier tails; their craniums had also changed shape, resulting in less sexual dimorphism, and they had lower levels of aggression overall.

Now, how does this relate to juvenilism? Well, in the wild, offspring grow up quickly and have to fend for themselves, which requires a certain ruthless degree of aggression. Cats and dogs, yes, they abandon their offspring soon enough, but those offspring continue to be tutored, tamed, domesticated under their human owners. We hear a lot about school bullying and gangs of youths, but they’re actually the exception rather than the rule, or a last ditch rebellion against the domestication pressure that’s exerted by the whole of society, and they’ll either succumb to that pressure or end up in jail, or worse. It’s a bit like the Freudian concept of sublimation, you channel your aggressive energies into creativity, competitive problem-solving, sports achievements and the like.

Canto: So you’re in favour of the domestication hypothesis?

Jacinta: Well, I’m not against it. It sounds plausible to me. Human domestication, or self-domestication if you want to call it that, is a social-contract sort of thing. You agree to outsource and comply with certain arrangements – laws, government, taxation and so forth, in return for certain benefits in terms of security and resources. So you don’t have to fend for yourself. And that affects the brain, obviously. Though it might not be the whole story.

what should a vegan’s pet eat, and other immortal questions

leave a comment »



Jacinta: So here’s a question – if vegans have pets – say a cat or a dog – do they feed them only vegetables?

Canto: I don’t know, I suppose it would depend on the vegan…

Jacinta: Shouldn’t it depend on the pet? Cats and dogs are carnivores aren’t they? So it would be a form of cruelty to deprive them of meat. Might even be murder.

Canto: We don’t extend murder to the killing of other animals.

Jacinta: Many vegans do.

Canto: Good point. I once read an article by a vegan philosopher, who gets out of those problems by declaring that using animals as pets is unethical. A form of slavery, I suppose.

Jacinta: So, we free the pets? Along with the cows, the sheep, the donkeys, the camels, the water buffalos, the horses, the chooks and pigeons and all those other creatures we’ve used and abused so horridly?

Canto: Well, from memory – I’ll never be able to hunt out the article – he didn’t address the issue of those animals already under captivity of one sort or another. He was simply wanting to argue on general principles that using animals for our personal benefit was unethical.

Jacinta: Even if it benefits the animal?

Canto: Well I suppose the argument would be that even a well-treated slave is still a slave.

Jacinta: But if you free a dog, say, what would happen to it? You’re actually throwing it out of its home, it has nowhere else to go. And I believe that there’s historical evidence that dogs, and probably cats too, have adapted to live with humans. That it was their choice, in a sense. Like pigeons in the city getting fat on leftover bits of hamburger, with no obvious ill-effects. Do pigeons get diabetes?

Canto: Well there’s an obvious difference between scavenging pigeons and pets. Pets don’t choose to become pets. I think that’s the way the argument would run. Unfortunately there are a lot of current pets who would suffer from being set free, but that’s not the issue.

Jacinta: I think I see. We look after the pets we’ve got, then bury them and don’t have any more. And this wouldn’t mean the end of all dogs because there are plenty of strays – scavengers – to maintain the species. And no more enforced ‘pedigree’ breeding – I’d be all for that. But there’s a problem – in order to get rid of all the pets, you have to stop them breeding and that would mean desexing them – a gross interference of their right to reproduce. And if you allow them to reproduce, you must surely bear responsibility for their offspring as your home is theirs. You’re caught in a trap, you can’t walk out, because you love them babies too much.

Canto: You’re looking at it all from a practical perspective, which is all fine and good and relevant, but I think the issue for this philosopher was, I think – judging from him being a vegan – that all such usage of animals – pets as cuddly toys, dolphins as trained performers, horses and camels as pack animals, etc, not to mention farming them for slaughter – is unethical. What do you think of that as a general principle?

Jacinta: I don’t think it holds up, because species take advantage of other species all the time, and not just by preying on them. Sharks have their remoras, we have lice more or less specially adapted to us, roses have their aphids, in fact everywhere you look you have species making use of other species. And presumably being a vegan he marks a strict boundary between animal and vegetable and in reality that’s quite a fuzzy boundary, like with coral. And what about insects, what’s the vegan take on that?

Canto: Presumably negative – they have eyes and antennae and feelings of some sort.

Jacinta: Yes, well it’s a step too far I think. Yes we have a moral responsibility to avoid causing undue suffering….

Canto: Well what about this argument. Because we can survive – and indeed thrive – on only plants, we should do so. I mean, you’re talking about species that, say, are mostly carnivorous – that won’t survive if their food supply dries up. Sharks, for example, they can’t just become vegan, they’ve adapted to a very specific diet. We on the other hand are omnivores, we can dispense with certain varieties of food, including meat, and still live healthy lives, perhaps.

Jacinta: Hmmm, that’s definitely a more difficult question. I do believe that being omnivores, or being very adaptable in our diet has stood us in very good stead in the past, like in the last major  ice age when we almost died out apparently. So I’m wondering whether confining our diet might not expose us to greater risks…

Canto: It may not even mean confining our diet – we could synthesise many of the proteins and other nutrients we nowadays get from meat. We’ve already done that, probably.

Jacinta: Well I’ve heard they’re still a long way from synthesising anything that really has the nutrients as well as the texture, flavour, odour and je ne sais quoi of meat. At under about $200, 000.

Canto: And if they achieved that feat, and got it down to competitive prices, would you go vego?

Jacinta: Well of course – I’d have no reason not to. I just don’t think it’ll happen in my lifetime.

Canto: But let’s say for argument’s sake that it does – would you feed this synthetic stuff to your pet cat?

Jacinta: Ah so we come full circle. Yes I would, since it would be more or less chemically identical to meat.

Canto: But animals that have adapted to become carnivores have also adapted to become hunters. They go together. Haven’t you turned your cat from its proper course in life?

Jacinta: No, she became removed from her ‘proper course’, if there is such a thing, by becoming my pet, whether by her choice or mine, or the choice of her ancestors. Likely she will keep up her hunting skills, catching flies and insects and mice and small birds, if she can. And she will benefit from being my friend, as I will benefit from being hers. Like all good friends, we’ll use each other for own purposes, which we hope will be, and will try to make, mutually beneficial.

Canto: Okay, no further questions your excellency.

The philosophers want more power

leave a comment »

tamsin shaw

tamsin shaw

Canto: Well I suppose the apparent detection of gravitational waves should be capturing our attention more than anything else right now, but it’s very well described in The Economist, and in many other places, and we’re no astrophysicists, and we did promise to focus a bit more on philosophical issues, so…

Jacinta: But we’re no philosophers. But we’re philosophasters at least, so let’s have a go.

Canto: Well I came across an article on Three Quarks Daily which vaguely gave me the irrits, so with your help I want to explore why.

Jacinta: Right. The essay is called ‘The psychologists take power’, the author is Tamsin Shaw and it was originally published in the New York review of books.

Canto: Yes, and on reading it in full I find it an interesting but confused piece, which seems to take the failings of certain individual psychologists as an example of the failings of psychology as a whole, and even of neurology. Shaw seems to be entering the philosophy versus science debate, on the side of philosophy, but I don’t find her arguments convincing.

Jacinta: The essay seems to divide into two parts, first a general critique of psychology and neurology, which can be summed up by the title of a philosophical essay by Selim Berker, which she quotes approvingly, ‘the normative insignificance of neuroscience’. The second part is an account of how certain professional psychologists, practitioners of the ‘positive psychology’ pioneered by the influential Martin Seligman, colluded with the US government in providing dubious evidence for the psychological effectiveness of torture in eliciting valuable information from ‘enemies of the state’. Shaw clearly wants to link these unethical practices to what she might want to call ‘the normative insignificance of psychology’.

Canto: Yes, and it’s a bit of a dangerous game – you might as well label Heidegger’s allegiance to the Nazi party, or Althusser’s murder of his wife, as examples of ‘the normative insignificance of philosophy’.

Jacinta: Ha, well Althusser was declared insane at the time, no doubt by psychologists, who would be examining Althusser to determine whether he was, while strangling his wife, capable of understanding and following the normative rules of his society. Such determinations are hardly normatively insignificant, even though, no doubt, individual psychologists might make different determinations, due to levels of competence, corruption, ideological considerations and so forth.

Canto: Right, but let’s look more closely at Shaw’s essay, and pick it apart.

Jacinta: Okay, but first let’s make a philosophasters’ confession. Shaw mentions eight or so books or sources at the head of her essay, which form the basis of her discussion, but of those we’ve only read one – Pinker’s eloquent tome, The better angels of our nature. And we don’t intend to bone up on those other texts, though no doubt we’ll refer to our own reading in our responses.

Canto: And we are reasonably familiar with Jonathan Haidt’s work and ideas.

Jacinta: So Shaw begins her essay with the overweening ambition of behaviourist extraordinaire B F Skinner, a pretty soft target these days. I have no problems with criticising him, or Freud or any other psychologist whose theories get way out of hand. Shaw’s concerns, though, are specifically about the moral sphere. She feels that a new breed of psychologists, armed with neurological research, are making big claims about moral expertise. Here’s a quote from her essay:

Neuroscience, it is claimed, has revealed that our brains operate with a dual system for moral decision-making.

Canto: I like the ‘it is claimed’ bit. Claimed by who? Someone has put forward that hypothesis I’m sure, along with their reasons, but most neurologists bang on about neurology being a field in its infancy, and most findings are highly contested, it seems to me.

Jacinta: Shaw may be referring to the work of Daniel Kahneman – a psychologist not a neurologist – who distinguished between system 1 thinking (intuitive, less conscious, rough-and ready) and system 2 thinking (reasoned, conscious, more changeable depending on inputs and knowledge). But really there are many dual-process theories going back at least to William James. But Shaw is explicitly referring to the fMRI imaging work of the neurologist Jonathan Cohen, who analysed brain activity when subjects were asked to think about moral hypotheticals.

Canto: Yes and she’s quite straight about describing the two systems apparently highlighted by Cohen’s research and the brain regions associated with them, but becomes scathing in dealing with Joshua Greene, Cohen’s co-researcher, whom she quite deliberately introduces as a mere ‘philosophy graduate student’, whose interpretation of the research she describes thus:

Greene interpreted these results in the light of an unverifiable and unfalsifiable story about evolutionary psychology. Since primitive human beings encountered up-close dangers or threats of personal violence, their brains, he speculated, evolved fast and focused responses for dealing with such perils. The impersonal violence that threatens humans in more sophisticated societies does not trigger the same kind of affective response, so it allows for slower, more cognitive processes of moral deliberation that weigh the relevant consequences of actions. Greene inferred from this that the slower mechanisms we see in the brain are a later development and are superior because morality is properly concerned with impersonal values—for example, justice—to which personal harms and goals such as family loyalty should be irrelevant. He has taken this to be a vindication of a specific, consequentialist philosophical theory of morality: utilitarianism.

Jacinta: Okay, so here’s where psychology – especially evolutionary psychology – first comes under attack. It’s often said to present just so stories, which are necessarily highly speculative, as if they are facts. But I would question whether these speculations, or hypotheses, are unverifiable (forget about falsifiability, a term made popular by Karl Popper but which has come under heavy criticism since, both by scientists and philosophers of science, and I suspect Shaw has simply used it as a ‘double whammy’ to vilify Greene), to me they’re important and useful, and in any case are rarely presented as facts, at least not by the best psychologists.

Canto: So how do you verify this hypothesis, that fast, rough-and-ready responses for dealing with immediate dangers are systematically different from slower, more sophisticated responses that deal with the ‘impersonal violence’, the many restraints, justified or not, on our personal freedoms that we deal with on a daily basis?

Jacinta: Well one obvious way is through neurology, a scientific field still in its infancy as you say. Clearly the system 1 responses would be shared by other complex social mammals, whereas system 2 thinking is much more language-dependent and unique to humans – unless cetaceans have developed complex language, which is far from being out of the question. New techniques for mapping and exploring neural pathways are coming up all the time, as well as non-invasive ways of exploring such pathways in our closest mammalian relatives.

Canto: Good point. So to go to the second part of the above quote, Greene is presented (and I wonder about whether Shaw is fairly or accurately presenting him) as finding system 2 thinking as superior because it deals with more abstract and less personal values, whereas I would prefer to think of this system as a further adaptation, to a human existence that has become more socially complex, systematic and language-based. And in this, I’m apparently in line with the thinking of psychologists Shaw takes aim at:

Many of the psychologists who have taken up the dual-process model claim to be dismissive of philosophical theories, generally. They reject Greene’s inferences about utilitarianism and claim to be restricting themselves to what can be proved scientifically. But in fact all of those I discuss here are making claims about which kinds of moral judgments are good or bad by assessing which are adaptive or maladaptive in relation to a norm of social cooperation. They are thereby relying on an implicit philosophical theory of morality, albeit a much less exacting one than utilitarianism.

Jacinta: But I detect a problem here. You’ve talked about adaptation to the fact of growing social complexity, and the need to co-operate within that complexity. Shaw has written of a ‘norm of social co-operation’, by which she means an ethical norm, because she claims that this is the implicit philosophical theory of morality these psychologists rely on. But that’s not true, they’re not claiming that there’s anything moral about social complexity or social co-operation. We just are more complex, and necessarily more co-operative than our ancestors. So it’s kind of silly to say they’re relying on a less exacting moral philosophy than utilitarianism. It’s not about moral philosophy at all.

Canto: And it gets worse. Shaw claims that this phantom moral ethic of social co-operation is greatly inferior to utilitarianism, so let’s look at that normative theory, which in my view is not so much exacting as impossible. Utilitarianism is basically about the maximising of utility. Act in such a way that your actions maximise utility (act utilitarianism), or create rules that maximise utility (rule utilitarianism). So what’s utility? Nothing that can be measured objectively, or agreed upon. We can replace it with happiness, or pleasure, or well-being, or Aristotle’s eudaemonia, however translated, and the problem is still the same. How do you measure, on a large-scale, social level, things so elusive, intangible and personal?

Jacinta: Yes, and look at how laws change over time, laws for example relating to homosexuality, women’s rights, the protection of minorities, and even business practices, taxation and the like; they’re all about our changing, socially evolving sense of how to co-operate in such a way as to produce the best social outcomes. This can’t be easily bedded down in some fixed normative ethic.

Canto: Yes, Shaw seems to imply that some deep philosophical insight is missing from these psychologists which makes them liable to go off the rails, as the second half of her essay implies, but I’m very doubtful about that. But let’s continue with our analysis:

Rather than adhering to the moral view that we should maximize “utility”—or satisfaction of wants—they are adopting the more minimal, Hobbesian view that our first priority should be to avoid conflict. This minimalist moral worldview is, again, simply presupposed; it is not defended through argument and cannot be substantiated simply by an appeal to scientific facts. And its implications are not altogether appealing.

Jacinta: But surely she’s just assuming that ‘they’ – presumably all the psychologists she doesn’t like, or is it all the psychologists who posit a two-tiered system of decision-making? – take the view that avoidance of conflict is the highest priority.

Canto: Well I must say that Jonathan Haidt seems to take that view, and it’s something I find uncomfortable. So I agree with Shaw that Haidt ‘presupposes that the norm of cooperation should take precedence over the values that divide us’, and that this view is dubious. It’s just that I suspect my own view, that there are values more important than co-operation, is also a ‘presupposition’, though I dislike that word. But more of that later perhaps.

Jacinta: Right, so Shaw refers to the sinister implications of a minimalist Hobbesian worldview, supposedly held by these psychologists. What are they?

Canto: We’ll get there eventually – perhaps. Shaw describes the work of the ‘positive psychology’ movement, stemming from Martin Seligman and practised by Haidt among others, including Steven Pinker, whose book The better angels of our nature was apparently influenced by this movement:

In that extremely influential work Pinker argues that our rational, deliberative modes of evaluation should take precedence over powerful, affective intuitions. But by “rationality” he means specifically “the interchangeability of perspectives and the opportunity the world provides for positive-sum games,” rather than any higher-order philosophical theory. He allows that empathy has played a part in promoting altruism, that “humanitarian reforms are driven in part by an enhanced sensitivity to the experiences of living things and a genuine desire to relieve their suffering.” But nevertheless our “ultimate goal should be policies and norms that become second nature and render empathy unnecessary.”

And here’s where I see another problem. Pinker is here criticised for not subscribing to any ‘higher-order philosophical theory’, but Shaw doesn’t attempt to outline or give examples of such higher-order theories, though she does refer to empathy – an important factor, but one that doesn’t obviously emerge from philosophy.

Jacinta: Right, and we’ve already referred to utilitarianism and its problems. This reminds me that years ago  I read a sort of primer on ethics, I think it was called Moral Philosophy, in which the author devoted chapters to utilitarianism, Kantianism, rights theory and other ethical approaches. In the final chapter he presented his own preferred approach, a sort of neo-Aristotelianism. I was intrigued that he felt we hadn’t made much progress in philosophical ethics in almost 2,500 years.

Canto: Well, his may be a minority view, but it’s doubtful that our changing laws derive from philosophical work on normative ethics, though this may have had an influence. I do think, with Haidt, that there’s a great deal of post-hoc rationalisation going on, though I’m reluctant – very reluctant actually – to embrace the relativism of values. And this brings me to the nub of the matter, IMHO. To go back to an old favourite of mine, Hume: ‘reason is and ought only to be the slave of the passions’. A fairly notorious pronouncement, but I take the passions here to be something very basic – the fundamental drives and instincts, largely unconscious, that characterise us as humans…

Jacinta: But doesn’t Hume break his own is-ought rule here? He says that our passions rule our reason, which may or may not be true, but does it follow that they ought to?

Canto: Please don’t complicate matters. Hume also wrote this, in An Enquiry Concerning the Principles of Morals:

In all determinations of morality, this circumstance of public utility is ever principally in view, and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind.

So these true interests of mankind…

Jacinta: Hang on, so there he goes again, gaily bounding over his own is-ought barrier, saying that in order to work out what we ought to do we need – pretty well absolutely – to determine our interests, what in fact makes us human, what we actually are.

Canto: Well, precisely…

Jacinta: Or what we have evolved to become, which might amount to the same thing. So we need to study our evolution, our genes and genetic inheritance, our brain and its inheritance, and adaptive growth, and maybe the physics of our bodies…

our old Scottish mate Davey Hume, doyen of skeptics, whose is-ought distinction has been widely misinterpreted, we suspect

our old Scottish mate Davey Hume, doyen of skeptics, whose is-ought distinction has been widely misinterpreted, we suspect

Canto: So we need neurology, and genetics, and palaeontology, and physics and psychology, all of which contribute to an understanding of what we are. Without them, normative ethics would be empty theorising.

Jacinta: So I suppose you’re going to write a rejoinder to this ‘normative insignificance of neurology’ essay? Something like ‘the insignificance of normative ethics without neurology’?

Canto: Ha, well that would require reading Selim Berker’s essay, which I’m not sure about – so many other things to explore. But I should end this discussion by saying a few words about the second half of Shaw’s article – and I’ll pass over many other points she’s made. This section deals with the collusion of some psychologists, practitioners of the above-mentioned ‘positive psychology’, with the CIA and the US Department of Defence in the commission of torture.

Jacinta: And what exactly is this ‘positive psychology’?

Canto: Well, to explain that would require a large digression. Suffice to say for now that it’s about using psychology to make us more resilient, and in some sense ethically superior, or more benign, humans. Shaw dwells on this at some length, but claims that in spite of much rhetoric, these psychologists can only offer what she calls the bare, Hobbesian ethic of avoidance of strife. However, she herself is unable to point to a more robust, or a deeper, ethic. She presumably believes in one, but she doesn’t enlighten us as to what it might be. And this is very striking because the tale of these psychologists’ collusion with the Bush administration  on torture, and the huge financial gain to them in applying ‘learned helplessness’, a theory of Seligman’s, to the application of torture, is truly shocking.

Jacinta: So it would be a question of what, in their make-up, allowed them to engage in such unethical behaviour, and was it the lack of a deep ethical understanding, beyond ‘bare Hobbesianism’?

Canto: Right, and my answer would be that, although two psychologists took up this lucrative offer to ‘serve the state’, there would have been others who refused, and would any of them, on either side, have made their decision on the basis of some rigorous normative ethic?

Jacinta: I’m quite sure I wouldn’t have colluded with that sort of thing for all the terracotta warriors in China, but I’m also sure it wouldn’t have been for deep philosophical reasons. I just have a kind of visceral revulsion for physical violence and bullying as you know, and I wouldn’t be able to live with myself if I’d facilitated the premeditated cruel and unusual punishment of others. I’m not even sure if it’s about empathy, but it’s not a particularly reasoned position.

Canto: Yes, and so the only way to understand why some people are more prone to do unethical things – actions outside of the ever-changing standards of community ethics – might be to look at individual psychology, and neurology, and genetics, which takes us further away from normative ethics than ever.

Jacinta: Yes, and didn’t we read, in Sam Kean’s The tale of the duelling neurosurgeons, about a poor fellow in his mid-fifties who suddenly started engaging in paedophile acts, something he had never showed any signs of before? A brain scan revealed a large tumour pressing on parts of the brain responsible for higher-order decision-making (to put it over-simplistically). When the tumour was removed he returned to ‘normal’, until some time later he regressed to paedophile acts. A further scan showed they didn’t remove all the tumour and it had regrown. After another more successful operation he was cured and never diddled again. But the consequences of his actions for his victims when ‘not himself’ would have required him to be punished, on a consequentialist ethical view, wouldn’t they?

Canto: Very good point. And yet, and yet… can it be true that we’ve barely gone further in our ethics than the Golden Rule, or Aristotle’s mean between extremes?

Jacinta: We’re animals, don’t forget. Okay we’re animals that have managed to detect waves from space that are a tiny fraction of the diameter of a proton, but we’re still not that good at being nice to each other. And the extent to which we’re able to be nice to each other, and follow social norms, that’s a matter of our individual psychology, our neurology, our individual and cultural circumstances, our genes and our epigenetic profile, so much particular stuff that philosophical ethics, with its generalities, can’t easily deal with.
