On Internet Relationships

December 7th, 2009 — 9:20pm

Many of the philosophers who have written on the internet have argued that internet relationships are in various ways diminished compared to everyday, embodied kinds. For example, Hubert Dreyfus in his On The Internet argues that:

our sense of the reality of things and people and our ability to interact effectively with them depend on the way our body works silently in the background. Its ability to get a grip on things provides our sense of the reality of what we are doing and what we are ready to do…All this our body does so effortlessly, pervasively, and successfully that it is hardly noticed. That is why it is so easy to think that in cyberspace we could get along without it, and why it would, in fact, be impossible to do so.

It is easy to understand how philosophers come to make these kinds of arguments. Many important facets of our personal relationships seem to require face-to-face contact. Dreyfus, for example, argues that trust in another person is in part based on the experience that they do not take advantage of our vulnerability when given the opportunity to so in a face-to-face situation. Certainly it does seem to be true that we can have a level of confidence in people we meet in person that is not available in online relationships. Particularly, the opportunity for gross deception is minimised in a face-face-situation. The philosopher Gordon Graham, and countless other people, have pointed out that it is very easy to deceive people on the internet by inventing wholly imaginary personas – something which it is much more difficult to achieve in the non-virtual world.

It’s Easy If You Get No Offers

December 3rd, 2009 — 12:11pm

This Tiger Woods thing is quite amusing, obviously. But if it is true that he has strayed, then really it isn’t surprising. Fidelity is (relatively) easy if beautiful people aren’t offering you sex all the time. If they are, as is presumably the case with Tiger Woods, then it gets a whole lot harder.

I used to think I’d always be able to resist the temptation of illicit sex. But now I’m pretty sure that if I had offers like Tiger Woods, I’d behave exactly as he has done. The flesh is weak.

Poor Bunny

November 25th, 2009 — 11:24pm

This is ridiculous. The boy was fifteen. It was consensual. If he is experiencing anything like trauma, it seems overwhelmingly likely that this is only because people make such a fuss about this kind of thing.

Yes, Madeleine Martin probably should have known better. Yes, the power relationship was likely asymmetrical. Yes, it isn’t a good idea for teachers to jump their students. But even so… let’s get some perspective here. It was sex that almost certainly both parties thoroughly enjoyed. It was just sex.

Here’s a newsflash for fifteen year old boys. If the worst thing that happens in your life is that you get shagged by your 39-year old teacher, then be thankful. And remember, there will almost certainly come a point in your life when you’ll be absurdly grateful if anybody wants to shag you.

Misunderstanding Richard Dawkins

October 5th, 2009 — 9:38am

Introduction

Richard Dawkins’s The Selfish Gene is the kind of book that changes the way that people look at the world. Its importance is that it articulates a gene’s-eye view of evolution. According to this view, all organisms, including human beings, are ‘survival machines’ that have been ‘blindly programmed’ to preserve their genes (see The Selfish Gene, p. v). Of course, extant survival machines take a myriad of different forms – for example, it is estimated that there are some three million different species of insect alone – but they all have in common that they have been built according to the instructions of successful genes; that is, genes whose replicas in previous generations managed to get themselves copied.

At the level of genes, things are competitive. Genes that contribute to making good bodies – bodies that stay alive and reproduce – come to dominate a gene pool (the whole set of genes in a breeding population). So, for example, if a gene emerges which has the effect of improving the camouflage of stick-insects, it will in time likely achieve a preponderance over alternative genes (alleles) which produce less effective camouflage. There are no such things as long-lived, altruistic genes. If a gene has the effect of increasing the welfare of its alleles to its own detriment, it will in the end perish. In this sense, then, all long-lived genes are ‘selfish’, concerned only with their own survival – and the world is necessarily full of genes which have successfully looked after their own interests.

Teachers, Dentists and Sex

September 21st, 2009 — 8:23pm

This story is disturbing on many different levels. The gist of it is that a 15 year old girl had trumpet lessons with a 26 year old female teacher. They became close. They fell in love. They had sex. There were complaints, a scandal, a court case, and the female teacher has ended up in prison.

The relationship was entirely consensual – indeed, it seems that there is the intention that it will continue once the teacher is freed from prison. The evidence in court was that the 15 year old girl was the one who pushed for the relationship to become sexual.

Regina Naughton, for the prosecution, said: “They began to have feelings which were not expected. Miss Goddard said she didn’t see her as a 15-year-old and they would have to wait until she was 16, or for three years. But flirting and the sending of text messages to each other began. The teenager described them kissing and then sleeping with each other, and it was at that point that the girl said she wanted a sexual relationship.

“The girl was told that if she felt anything was uncomfortable at any time they could stop. But the girl said it felt right,” she added.

There are a number of points to be made here.

Can secular humanism be a kind of brainwashing?

May 14th, 2009 — 7:59am

brainwashing_small

Richard and Dan live in a society that is thoroughly and harmoniously religious. People are happy. They sing hymns together, burn incense, enjoy wearing robes and have a penchant for incantation. There exists little in the way of what we would recognize as education. Children are taught about God, sacred traditions, the importance of family and community, the truth of the Holy Scripture, but that’s about it.

Richard and Dan, however, do not share the religious sensibility of their fellow citizens. They were brought up by their parents – members of the renegade Enquiries at the Periphery – to be secular humanists. As teenagers, they were closeted away, and put through an intense educational program designed to teach them the overriding importance of science and scientific methodology. At first, Richard and Dan resisted the efforts of their teachers, preferring the simplicity of the beliefs of their early childhood, but the pressure from their teachers was relentless, and inevitably they came to embrace a scientific worldview.

However, their education has not made them happy. They are alienated from the society in which they live, and they find themselves wishing that they could be more like other people – that they could experience the exuberance of happy singing, the joy of worshipping the God they do not believe exists, and the togetherness engendered by a shared belief. But try as they might, they simply cannot believe. It is impossible. They know that their way of understanding the world is the right way, but they wish it were otherwise.

Richard and Dan live lonely, miserable, friendless lives. They are considerably less happy than they would have been had they not been born to proselytizing secular humanist parents. If you ask them about it, they’ll tell you that they were brainwashed as teenagers – that they were victims of a kind of abuse, which has left them unable to live as full members of their society.

***

The notion of brainwashing usually carries with it the idea that a victim has been forced or pushed to believe various things that are palpably false or absurd. The scenario above subverts this idea by asking us to consider whether it is right to describe as brainwashing the inculcation of a worldview that many people think is rationally justified. Richard and Dan are committed to the truth of secular humanism, but they claim that they cannot help but think that way – despite their desire not to do so – because of the nature of their upbringing and education. They have, in effect, been brainwashed.

A possible objection here is to insist that part of what defines brainwashing is that it involves employing specific psychological techniques – such as isolation and emotional manipulation – in order to ensure that people come to believe particular things. The trouble is that this definition seems to leave too much out. Consider, for example, that the scientist Richard Dawkins, and philosopher Anthony Grayling, and many others like them, have suggested that the normal religious education provided by churches, mosques and synagogues is “brainwashing” and “child abuse”.

Perhaps then what defines brainwashing is that it involves the passing on of beliefs that are presented as being unquestionably true. This allows in the teaching of religion as a kind of brainwashing. The trouble is that it also allows in an awful lot else. Just think about how history was taught for a large part of the twentieth century: facts and dates – no questioning, no dissent, and nothing to suggest that the details of history are contested. So was the teaching of history – and anything else taught in a similar fashion – a kind of brainwashing? Perhaps it was.

Maybe the only way to avoid the brainwashing charge is to cultivate a restless and questioning spirit in people through our educational practices. But here the case of Richard and Dan looms large again. They were both precisely taught to be restless and questioning, and it is their claim that they have been damaged as a consequence. For them, it is their inability to leave behind the legacy of their “enlightened” education that has left them isolated and estranged.

This is a reworking of a post that originally appeared on the Talking Philosophy blog.

Not a very bright idea

April 8th, 2009 — 10:04am
brights_small

Daniel Dennett

When Tony Blair first became leader of the Labour Party in 1994, the Sun newspaper, a British tabloid, took to calling him ‘Bambi’, presumably in the hope that the nickname would become established in the public consciousness. It did not, of course, for it lacked any kind of resonance with what people could believe about Blair. He wasn’t a child, his leadership was anything but childlike, and he lacked the requisite number of legs to be a baby deer. Not discouraged, the Sun was at it again in 2001, this time when Iain Duncan Smith became leader of the Conservative Party. In what was probably a desperate attempt to establish his man of the people credentials, it started to call him ‘Smithy’. A quite absurd conceit, given his double-barrelled name and former career as an army officer. Needless to say, this nickname didn’t catch on either, and almost universally in the UK media, Duncan Smith came to be known as IDS.

None of this is surprising. If your aim is to coin, ex nihilo, a name or epithet which quickly gains widespread public acceptance, the chances of success are not great. Even the media, with its ability to talk daily to massive audiences, fails as often as it succeeds. Thus, for every ‘Slick Willy’, you’ll find that there is a ‘Bambi’, for every ‘loony left’ a ‘Doris Karloff’.

This is a comforting thought for a secularist at the present time. For a rather unfortunate meme has lately infected the minds of some leading exponents of a naturalistic worldview. It is a meme which says that it would be a good idea if people without belief in things supernatural started to call themselves ‘brights’.

The meme started with two people from Sacramento, California. Though atheists, Paul Geisert and Mynga Futrell did not want to be referred to as being ‘godless’, so they came up with the word ‘bright’ to better describe their naturalistic worldview. Their hope is that other nonbelievers will also use the word, and that it will become an umbrella term for the whole range of naturalistic philosophies (i.e., atheist, agnostic, humanist, etc.). They have setup a website, The Brights Net (www.the-brights.net), to this end, and have attracted a number of high profile advocates, including Richard Dawkins and Daniel Dennett, both of whom have written articles supporting the idea.

It is easy enough to understand the efficacy of this meme. The naturalistic philosophies of the non-religious do not play the same kind of high profile role in political and civic life as do the supernaturalist ideas of their religious counterparts. This is the case particularly in the United States, but also in the United Kingdom, where, for example, assorted bishops get to sit on various ethics committees simply because they are bishops. Given this situation, any intervention which promises to raise the profile of naturalistic thinking is bound to be attractive at first sight. The trouble is that it doesn’t take too many more sights of the brights idea to realise that it is badly flawed.

First, ‘bright’ is just the wrong word. How it was chosen in the first place isn’t quite clear. It seems to have had something to do with the fact that it is a ‘positive’ and ‘memorable’ word; and also that it is sufficiently puzzling or enigmatic when used as a noun – ‘I am a bright’ –that it invites the response, ‘What’s a bright?’, thereby allowing a person to talk about their naturalistic worldview. But there are major problems with the word.

The first is that its enigmatic quality is indicative of a fundamental arbitrariness in its relationship to the phenomenon that it names. It’s the let’s call Tony Blair ‘Bambi’ problem. Dawkins imagines that a bright might have a conversation which goes like this:

‘”What on earth is a bright”? And then you’re away. “A bright is a person whose world view is free of supernatural and mystical elements….”

“You mean a bright is an atheist?”

“Well, some brights are happy to call themselves atheists. Some brights call themselves agnostics. Some call themselves humanists, some freethinkers. But all brights have a world view that is free of supernaturalism and mysticism.”’

(Richard Dawkins, ‘The future looks bright’, The Guardian, June 21st 2003)

All very nice, except that the conversation is far more likely to go something like this:

‘What on earth is a bright?’

‘A bright is a person whose world view is free of supernatural and mystical elements.’

‘Right. So why the word “bright” then?’

‘Err. Well it’s a positive word. And memorable.’

‘So is the word “truffle”, but you wouldn’t call yourself a truffle. So why “bright”?’

‘Well, it’s what this couple from Sacramento came up with… and it is a very cheerful word!’

The arbitrariness of the choice of the word ‘bright’, though undermining its potential as a meme, would not matter so much were it not for the fact that one of the established uses of the word is as an adjective meaning ‘clever’ or ‘intelligent’. The problem here is that in the absence of an obvious reason to explain how it is that the word ‘bright’ designates a person who espouses a naturalist worldview, it is easy to jump to the conclusion that what is being suggested is that it is more intelligent to embrace naturalism than it is to embrace supernaturalism.

It must be said that the supporters of the brights idea are quite clear that the word should not be taken to be an adjective in this way. However, this does not make the problem go away. It should be obvious why it does not. For starters, there is the trivial point that you cannot strip a word of its associations simply by denying that you intend them. [1] Nor can you do so by using the word in a slightly strange way (i.e., as a noun). If someone announces that they’re a bright, then likely it will occur to their audience that what they actually mean is that they are bright. The fact that they will also be unable to explain why the word ‘bright’ is appropriate as a label for someone with a naturalistic worldview will do nothing to allay this suspicion.

There is also a slightly more complex point to be made here. To be an atheist in the United States – and also in some ways in the United Kingdom – is to set oneself against the dominant culture. There is, therefore, a tendency to associate atheism with a certain kind of intellectual independence. This is reflected in the names of the groups with which many atheists associate themselves (e.g., freethinkers; skeptics; etc). And it also underpins the anti-intellectual sentiment of much of the religious sermonising characteristic of Christian fundamentalism. The problem with the word ‘bright’ is that it is too easily seen as confirming this link between atheism and intellectuality. Or to put this more precisely, if people with no belief in god begin to self-identify as brights, they run the risk of apparently confirming what many religious people already suspect about them, that they consider themselves to be better or more intelligent than people who believe in a god.

Does this matter? Yes it does, if one is interested in convincing people of the merits of a naturalistic worldview. To start with, there is the obvious point that people are more likely to be receptive to new ideas if they feel that they are being treated with respect. But perhaps more worryingly, a movement which self-identifies as a movement of brights makes itself a hostage to rhetorical fortune. It is extremely easy – and, it must be said, very tempting – to parody the whole idea of a brights movement. And, of course, this is exactly what the enemies of a naturalistic worldview will do should the idea take off. The brights movement will find itself transmogrified into a ‘We’re smarter than you’ movement. And, at that point, protesting that the word was chosen simply because it is ‘warm’ and ‘cheerful’ will just result in more parody and more laughter.

‘Bright’, then, is the wrong choice of word to designate a person with a naturalistic worldview and as an umbrella term for a movement. But substituting a different word won’t make the brights idea a good one because it is muddle-headed for other reasons. Perhaps the most interesting of these has to do with what appears to be an unspoken assumption about people with a naturalistic worldview.

The assumption seems to be that the rejection of supernaturalism is enough to qualify someone as a person without religion. This claim is only unproblematic if one defines religion as involving supernatural beliefs. However, there is at least an argument that the sphere of the religious can be extended to include aspects of the secular world. It is an argument inspired by the French sociologist Emile Durkheim. He claimed that the realm of the sacred is distinguished by the separateness of its objects from those of the world of the profane, and by the system of interdictions which prevents them from being denied. [2] If one accepts this conception, then there are secular phenomena which qualify as sacred. So Durkheim talks of ‘common beliefs of every sort connected to objects that are secular in appearance, such as the flag, one’s country, some forms of political organisation, certain heroes or historical events’, which are ‘indistinguishable from beliefs that are properly religious’; and he notes that ‘Public opinion does not willingly allow one to contest the moral superiority of democracy, the reality of progress, [or] the idea of equality, just as the Christian does not allow his fundamental dogmas to be questioned.’

It is easy to understand what Durkheim is getting at. It is only necessary to attend a meeting organised by a group like the Socialist Workers Party to become very quickly aware that people can hold secular beliefs to be every bit as inviolable as religious beliefs often are for the religious. Of course, this point is already well understood. For example, in a review of Steven Rose et al’s Not in Our Genes, Richard Dawkins, commenting on their arguments against ‘genetic determinism’, has this to say: ‘The myth of the “inevitability” of genetic effects has nothing whatever to do with sociobiology, and has everything to do with Rose et al’s paranoiac and demonological theology of science. [my italics]’ (Richard Dawkins, New Scientist 24 January 1985).

What this means for the brights idea is that the criterion of a naturalistic worldview is no guarantee that people will be free of the kind of thinking which is quite reasonably described as ‘religious’. Or to put this another way, it is no guarantee that people will not be committed to beliefs, or sets of beliefs, which are beyond rational scrutiny in the same way as are many of the beliefs which are associated with theism. Possibly the supporters of the brights movement will not deny this, but rather claim that it does not matter too much, that their expectation has never been that they will create a movement of absolutely rigorous thinkers, each one holding up their beliefs to the light of reason. Fair enough. Except for two further points.

First, there is just a suggestion in some of the writings of the supporters of the brights idea that they see themselves as the true inheritors of the Enlightenment tradition. Well, it just isn’t this clear-cut. First off, the belief in a deity, in and of itself, does not rule out an attitude towards this world which is entirely consistent with the Enlightenment emphasis on reason and the progress of human knowledge. But perhaps more significantly, many people who qualify as brights would have a decidedly ambivalent attitude towards the products of the Enlightenment. Just consider, for example, that many Marxists would agree with Rose et al that ‘science is the ultimate legitimator of bourgeois ideology.’ (Not in Our Genes). And that from amongst the whole caboodle of postmodern thinkers, at least some will be prepared to commit to agnosticism, and will no doubt claim something like ‘that progress in social thought is not possible without a thorough critique of the Enlightenment, whether for its justification of the domination of nature, or its authoritative support for belief systems like scientific racism or sexism, or for the monocultural legacy of its assumptions about rationality.’ (Andrew Ross, The Sokal Hoax).

Which thoughts lead on to the second point about the kind of movement the brights idea is likely to foster. It is certainly going to contain some odd bedfellows. Scientific atheists and Marxist atheists will be united in thinking that there is definitely no god, but they’ll fight like cats and dogs over the fate of the bourgeoisie. The agnostics will irritate both groups by sitting on the fence, whilst freethinkers drive themselves crazy trying to find a viewpoint unique to themselves. The skeptics will watch the whole thing from afar with slightly cynical smiles, and the postmodernists will talk past themselves, as per usual. As for the rest of the world? They won’t see past the name. And laughter and parody will be the result. Therefore, one can only hope that the ‘bright’ meme fails on its evolutionary journey.

Behaving badly on the internet

March 31st, 2009 — 11:44pm

fingerA little while ago I received an email commenting on my writing ability. It contained phrases like: “you’d better pull your socks up”; “very, very disappointing”; and “you indulge in appalling syntax”. So it wasn’t exactly fan mail. But no big deal, if you put stuff out in the public domain, then you expect to get shot at.

Here’s another one, this time about one of the activities which are featured at TPM Online:

I find your questions biased, short-sighted and bigoted; and I find your test without merit or foundation… which makes you bass and without spiritual wisdom. Sad.

Okay, so that one’s a little odd, especially the bit about the freshwater fish, but there’s not much harm there. However, what about this little missive: 

…your litany of frauds and charlatans does not include a noble exception, the one modern philosopher who was neither a fraud nor a charlatan, but who exposed your own pretentious, social-climbing bullshit – Ayn Rand. So wallow in your pseudo-respectability and slash your wrists accordingly…You’re a pathetic wanker who deserves to perish from a surfeit of self-indulgent whim-worship. Do it, with my blessing, and that of any half-decent human thinker who miraculously remains alive on this earth in spite of your demeaning of philosophy and life.

This email was sent to me by the editor of an online journal promoting “freedom”, who was upset, as far as I can tell, by the failure of TPM to include any of the works of Ayn Rand in its shortlist of the greatest writings of Western philosophy. What makes it interesting is that it is indicative of a certain disregard for those we interact with on the internet. It is the disregard, evident to varying degrees in all the emails cited above, of treating people as though they don’t automatically warrant the respect which would nearly always be forthcoming in a non-virtual context. Consider, for example, that it is almost impossible to imagine saying the kinds of things contained in these emails to a stranger in a face-to-face situation. Yet probably many of us will be able to imagine including at least some of them in an email.

Part of the explanation for this difference has to do with some fairly obvious stuff about email communication. First, email is pretty much instantaneous. Therefore, it is just more likely with email that things will be said in haste which would not have been said had more time been taken for reflection. Second, the internet facilitates relatively anonymous communication. Consequently, in our virtual lives, we’re more likely to be interacting with people we’ve never met, we’re never going to meet, and whom we don’t know anything about. In such a situation, there is more chance that we will treat them as though they are not quite fully human subjects. And third, internet communication involves geographical distance, which removes many of the barriers to aggressive behaviour which exist in the non-virtual world. Not least, you’re not likely to get hit for sending someone an abusive email, whereas this is certainly a possible response to abuse in a face-to-face situation.

However, though these factors are all significant, they are only part of the story. What is also important is that the conventions which have grown up around email usage are much more loose than is the case with other forms of written communication. For example, when writing an email, many people think nothing of dispensing with: a salutation; capital letters; complete sentences; complimentary closing phrase; and even – though it is generally considered to be bad netiquette – correct spelling. The advantage of this informality is primarily speed, but it is an advantage often bought at the expense of a concern for the person who has to read the email.

The conventions of email are based on an assumption that what is important in communication is overwhelmingly the content of the message, not the perceptions and feelings of the person who receives it. This is very different from letter writing, for example, where many of the traditional stylistic conventions, some of which are still in common usage, are employed precisely to communicate a certain kind of, albeit ritualistic, regard for the recipient of the letter. To fail to include a salutation in a letter, for example, will, more often than not, be taken to indicate a lack of respect.

The claim here is not that people never show concern for each other when they exchange emails because clearly they do. It is rather that there is no requirement that they should show such concern; that day to day, in many of the short and perfunctory emails which people send, they do not show such concern; and that as a result there is a tendency for them to pay insufficient regard to how their emails are likely to be received when the content of their message suggests that such regard is required (as, for example, when they send a rude or abusive email). Or to put this another way, the informality and speed of email communication will in certain circumstances subvert what is arguably a moral requirement to treat those with whom we interact as fully human subjects.

Are philosophers immune to this tendency? Unfortunately not. Check out, for example, some of the emails about the Israel/Palestine conflict in the archive of philos-l (http://listserv.liv.ac.uk/archives/philos-l.html), the premier mailing list for UK philosophers. You won’t learn anything much about the Middle East conflict, but you’ll find plenty of evidence of philosophers behaving badly in their virtual lives.

Other Examples

Louis Proyect, Unrepentent Marxist, calls me a “Neocon scumbag” and “Creepy Crawly” (the mind boggles!).

Daniel Davies calls me a liar (in effect) (not email, though).

In both these instances, Ophelia Benson at Butterflies and Wheels tells the story.

Charles Darwin’s brilliant idea

March 27th, 2009 — 10:30pm

darwin_smallThere are a number of candidates for the single most powerful idea in the history of the sciences and humanities. Nicolaus Copernicus’s heliocentric view of the Earth’s place in the universe is certainly one, as is Einstein’s theory of relativity. However, for the breadth of its application, and the impact that it had on modern civilisation, it would be hard to beat Charles Darwin’s theory of evolution by natural selection.

Until Darwin’s The Origin of the Species was published in 1859, it was hard to see how the natural world could have been anything other than designed. The significant point here is its complexity. As William Paley famously argued, it seems almost unimaginable that something as complex and highly wrought as the human eye could possibly have emerged purely by natural mechanisms. The eye just appears too precisely specified to be anything other than the creation of an intelligent entity (by which just about everybody means God). Darwin’s importance is that he showed exactly how this kind of “design” could have occurred without a designer.

Darwin was influenced by Thomas Malthus’s famous essay on population, in which Malthus argued that the capacity of a population to sustain itself tends not to keep up with its rate of growth. The lesson that Darwin took from this is that the living world is necessarily thoroughly competitive (“red in tooth and claw”, as one of his disciples later put it). Life is characterised by a struggle for existence – or, more exactly, for reproduction – since any species will tend to produce more individuals than can be sustained. It was this insight that led Darwin to his theory of evolution by natural selection.

Every species manifests some variation in the inherited traits of its members. Take foxes, for example: some foxes will be able to run faster than other foxes; some will have better eyesight, better hearing, sharper teeth, and better camouflage. Variations that give an individual a competitive advantage (e.g., sharper teeth and better eyesight) will tend to be passed on more often than variations that put an individual at a disadvantage (e.g., a birthmark that makes its bearer a sitting target). Therefore, given enough time, helpful variations will come to be much more numerous than less helpful variations. So long as there are always new variations for natural selection to operate upon, then evolution will carry on in this way indefinitely.

This is a hugely powerful idea. It answers Paley’s challenge to explain how the eye could have emerged naturalistically: by means of tiny, incremental steps, each one beneficial in its own right. In Darwin’s day, the mechanisms of inheritance, and the source of the variations upon which natural selection works, were not known. It was only at the turn of the twentieth century, with the rediscovery of the ideas of Gregor Mendel, that this became clearer. One hundred years later, we now know that genes are the units of inheritance; and that, every so often, they mutate to produce new characteristics in an organism, which are then subject to Darwinian selection.

Darwin’s importance simply cannot be overstated. He was the founder of modern biology; the person who, in Huxley’s phrase, put the world of life into the domain of natural law.

Animal rights, humanists and wishful thinking

March 25th, 2009 — 9:52am
Fluffy Bunny

Fluffy Bunny

Human beings are very good at believing things to be true just because they want them to be true. In some ways, this is a useful ability. For example, the belief that one will beat a normally deadly cancer is helpful if one is undergoing the painful chemotherapy required to give one any chance of survival at all. However, when it comes to our ability to discern the truth about the world, to assess evidence and argument according to the dictates of rational enquiry, our tendency to engage in wishful thinking is no help whatsoever.

Consider, for example, the part that it plays in the currently high profile debate over animal rights and vivisection. It is perfectly possible to object to animal experimentation on moral grounds: for example, one might hold that all life is sacred and that it should always be preserved. However, it is much more difficult to argue that animal experimentation is unnecessary because it has no scientific benefit. Colin Blakemore, one time head of the MRC (Medical Research Council), points out that:

Every drug, every form of advanced surgery, nearly every antibiotic, nearly every vaccine – the development of them all has at some stage involved animal testing… every pain killer; every treatment for heart disease, kidney disease and cancer; chemotherapy; radiotherapy; surgical techniques; bypass surgery; open heart surgery – you name it, animals were involved in the research.

Yet the line taken by many anti-vivisectionists is precisely that animal research has little, if any, medical benefit. For example, the section on “Bad Science” on the SPEAK web site is headed up with the claim that “Using primates kills people”. Further reading reveals that 70,000 people in England each year are killed or disabled by drugs that have been tested on animals.

It is easy enough to demolish this kind of argument: whilst it is true that whenever a drug is associated with a bad outcome, then animal testing will have been part of its development (because all drugs are tested on animals), it is also true: that we judge that the risks associated with powerful drugs are worth it; that we would be worse off in terms of deaths and injuries had there been no animal testing; and that we are overwhelmingly better off in general as a result of drugs that have been developed using vivisection.

Perhaps what is more interesting than the details of the (risible) arguments employed by anti-vivisectionists is the neat correspondence they set up between the wished-for and the real; that is, between the almost visceral desire for a world where there is no animal experimentation, and the claim that by happy coincidence our world does not reward animal experimentation. This kind of wishful thinking short-circuits the necessity to engage in messy and complicated arguments about morality and the relative value of human and animal life. It constitutes both intellectual and moral cowardice.

There is an interesting contrast here with the position of the vivisectionists. They too desire a world without animal experimentation, but recognise that it is not available unless we forego benefits to medical research. Here’s Blakemore again:

If there are alternatives [to animal research], let’s see them. We want them. I don’t know of a single person who uses animals in their research, who wouldn’t rather use an alternative.

It isn’t just anti-vivisectionists who engage in wishful thinking, of course. In fact, wishful thinking is ubiquitous, which is something we need to worry about if we are interested in finding out the truth about things. Consider, for example, that the recent history of the social sciences is replete with examples of an almost childish desire to reconstruct the world through the filter of political, ideological and moral commitments. Marxist theorists spent a large part of the twentieth century falling over each other trying to explain why revolution hadn’t occurred quite yet; sociologists, desperate to detach human behaviour from biology, spent their time jumping through hoops in order to explain away data that suggested that at least some human attributes and behaviour are inherited; and anthropologists, even today, in the name of resisting Western hegemony, happily grant epistemological privilege to local and situated “knowledges”.

Even people ostensibly committed to rational enquiry fall into the trap of wishful thinking. It ill behoves humanists, self-appointed defenders of reason par excellence, to sneer at the likes of Philip Gosse for supposing that the fossil record has been planted by God, whilst they remain committed to the view that it will be possible to reconcile the human-centred aspects of humanism with what science teaches us about the natural world and our place in it. The jury is still out on whether things such as free will, moral responsibility and the idea of human progress will survive the increases in knowledge that science brings. To suppose otherwise is to engage in wishful thinking. It might be more subtle than the kind engaged in by anti-vivisectionists or Philip Gosse style Biblical literalists, and perhaps it will be passed off as understandable optimism, but it no less wishful thinking for that. It is just another example of the way in which ideological, moral and political commitments tend to infect the judgements that we make about the world.
