I suspect that quite a lot of religious people do think religion is what motivates them to be good, especially if they belong to one of those faiths that systematically exploits
personal
guilt.
Richard-Dawkins-God-Delusion
Natural selection favours genes that predispose individuals, in relationships of asymmetric need and opportunity, to give when they can, and to solicit giving when they can't.
It also favours tendencies to remember obligations, bear grudges, police exchange relationships and punish cheats who take, but don't give
when their turn comes.
For there will always be cheats, and stable solutions to the game-
theoretic conundrums of reciprocal altruism always involve an element of punishment of cheats. Mathematical theory allows two broad classes of stable solution to 'games' of this kind. 'Always be nasty' is stable in that, if everybody else is doing it, a single nice individual cannot do better. But there is another strategy which is also stable. ('Stable' means that, once it exceeds a critical frequency in the population, no alternative does better. ) This is the strategy, 'Start out being nice, and give others the benefit of the doubt. Then
218 T H E Ci O D I) E I. U S I O N
repay good deeds with good, but avenge bad deeds. ' In game theory language, this strategy (or family of related strategies) goes under various names, including Tit-for-Tat, Retaliator and Reciprocator. It is evolutionarily stable under some conditions in the sense that, given a population dominated by reciprocators, no single nasty individual, and no single unconditionally nice individual, will do better. There are other, more complicated variants of Tit-for-Tat which can in some circumstances do better.
I have mentioned kinship and reciprocation as the twin pillars of altruism in a Darwinian world, but there are secondary structures which rest atop those main pillars. Especially in human society, with language and gossip, reputation is important. One individual may have a reputation for kindness and generosity. Another individual may have a reputation for unreliability, for cheating and reneging on deals. Another may have a reputation for generosity when trust has been built up, but for ruthless punishment of cheat- ing. The unadorned theory of reciprocal altruism expects animals of any species to base their behaviour upon unconscious responsiveness to such traits in their fellows. In human societies we add the power of language to spread reputations, usually in the form of gossip. You don't need to have suffered personally from X's failure to buy his round at the pub. You hear 'on the grapevine' that X is a tightwad, or - to add an ironic complication to the example - that Y is a terrible gossip. Reputation is important, and biologists can acknowledge a Darwinian survival value in not just being a good reciprocator but fostering a reputation as a good reciprocator too. Matt Ridley's The Origins of Virtue, as well as being a lucid account of the whole field of Darwinian morality, is especially good on reputation. *
The Norwegian economist Thorstein Veblen and, in a rather different way, the Israeli zoologist Amotz Zahavi have added a further fascinating idea. Altruistic giving may be an advertisement of dominance or superiority. Anthropologists know it as the Potlatch Effect, named after the custom whereby rival chieftains of
* Reputation is not confined to humans. It has recently been shown to apply to one of the classic cases of reciprocal altruism in animals, the symbiotic relation- ship between small cleaner fish and their large fish clients. In an ingenious experiment, individual cleaner wrasse, Labroides dimidiatus, that had been observed by a would-be client to be diligent cleaners were more likely to be cho- sen by the client than rival Labroides that had been observed neglecting to clean. See R. Bshary and A. S. Grutter, 'Image scoring and cooperation in a cleaner fish mutualism', Nature 441, 22 June 2006, 975-8.
THF, ROOTS OF MORALI TY: WHY ARE WE GOOD? 219
Pacific north-west tribes vie with each other in duels of ruinously generous feasts. In extreme cases, bouts of retaliatory entertaining continue until one side is reduced to penury, leaving the winner not much better off. Veblen's concept of 'conspicuous consumption' strikes a chord with many observers of the modern scene. Zahavi's contribution, unregarded by biologists for many years until vindicated by brilliant mathematical models from the theorist Alan Grafen, has been to provide an evolutionary version of the potlatch idea. Zahavi studies Arabian babblers, little brown birds who live in social groups and breed co-operatively. Like many small birds, babblers give warning cries, and they also donate food to each other. A standard Darwinian investigation of such altruistic acts would look, first, for reciprocation and kinship relationships
among the birds. When a babbler feeds a companion, is it in the expectation of being fed at a later date? Or is the recipient of the favour a close genetic relative? Zahavi's interpretation is radically unexpected. Dominant babblers assert their dominance by feeding subordinates. To use the sort of anthropomorphic language Zahavi delights in, the dominant bird is saying the equivalent of, 'Look how superior I am to you, I can afford to give you food. ' Or 'Look how superior I am, I can afford to make myself vulnerable to hawks by sitting on a high branch, acting as a sentinel to warn the rest of the flock feeding on the ground. ' The observations of Zahavi and his colleagues suggest that babblers actively compete for the dangerous role of sentinel. And when a subordinate babbler attempts to offer food to a dominant individual, the apparent generosity is violently rebuffed. The essence of Zahavi's idea is that advertisements of superiority are authenticated by their cost. Only a genuinely superior individual can afford to advertise the fact by means of a costly gift. Individuals buy success, for example in attracting mates, through costly demonstrations of superiority, including ostentatious generosity and public-spirited risk-taking.
We now have four good Darwinian reasons for individuals to be altruistic, generous or 'moral' towards each other. First, there is the special case of genetic kinship. Second, there is reciprocation: the repayment of favours given, and the giving of favours in 'anticipation' of payback. Following on from this there is, third, the Darwinian benefit of acquiring a reputation for generosity and
220 i H r o o i> i) hi (i s i o N
kindness. And fourth, if Zahavi is right, there is the particular additional benefit of conspicuous generosity as a way of buying unfakeably authentic advertising.
Through most of our prehistory, humans lived under conditions that would have strongly favoured the evolution of all four kinds of altruism. We lived in villages, or earlier in discrete roving bands like baboons, partially isolated from neighbouring bands or villages. Most of your fellow band members would have been kin, more closely related to you than members of other bands - plenty of opportunities for kin altruism to evolve. And, whether kin or not, you would tend to meet the same individuals again and again throughout your life - ideal conditions for the evolution of reciprocal altruism. Those are also the ideal conditions for building a reputation for altruism, and the very same ideal conditions for advertising conspicuous generosity. By any or all of the four routes, genetic tendencies towards altruism would have been favoured in early humans. It is easy to see why our prehistoric ancestors would have been good to their own in-group but bad - to the point of xenophobia - towards other groups. But why - now that most of us live in big cities where we are no longer surrounded by kin, and where every day we meet individuals whom we are never going to meet again -- why are we still so good to each other, even some- times to others who might be thought to belong to an out-group?
It is important not to mis-state the reach of natural selection. Selection does not favour the evolution of a cognitive awareness of what is good for your genes. That awareness had to wait for the twentieth century to reach a cognitive level, and even now full understanding is confined to a minority of scientific specialists. What natural selection favours is rules of thumb, which work in practice to promote the genes that built them. Rules of thumb, by their nature, sometimes misfire. In a bird's brain, the rule 'Look after small squawking things in your nest, and drop food into their red gapes' typically has the effect of preserving the genes that built the rule, because the squawking, gaping objects in an adult bird's nest are normally its own offspring. The rule misfires if another baby bird somehow gets into the nest, a circumstance that is positively engineered by cuckoos. Could it be that our Good Samaritan urges are misfirings, analogous to the misfiring of a reed
\ I i ' ) K A I I M : \ V 1 ! \ A i d S I t , t ' ' i i i ) '? 221
warbler's parental instincts when it works itself to the bone for a young cuckoo? An even closer analogy is the human urge to adopt a child. I must rush to add that 'misfiring' is intended only in a strictly Darwinian sense. It carries no suggestion of the pejorative.
The 'mistake' or 'by-product' idea, which I am espousing, works like this. Natural selection, in ancestral times when we lived in small and stable bands like baboons, programmed into our brains altruistic urges, alongside sexual urges, hunger urges, xenophobic urges and so on. An intelligent couple can read their Darwin and know that the ultimate reason for their sexual urges is procreation. They know that the woman cannot conceive because she is on the pill. Yet they find that their sexual desire is in no way diminished by the knowledge. Sexual desire is sexual desire and its force, in an individual's psychology, is independent of the ultimate Darwinian pressure that drove it. It is a strong urge which exists independently of its ultimate rationale.
I am suggesting that the same is true of the urge to kindness - to altruism, to generosity, to empathy, to pity. In ancestral times, we had the opportunity to be altruistic only towards close kin and potential reciprocators. Nowadays that restriction is no longer there, but the rule of thumb persists. Why would it not? It is just like sexual desire. We can no more help ourselves feeling pity when we see a weeping unfortunate (who is unrelated and unable to reciprocate) than we can help ourselves feeling lust for a member of the opposite sex (who may be infertile or otherwise unable to reproduce). Both are misfirings, Darwinian mistakes: blessed, precious mistakes.
Do not, for one moment, think of such Darwinizing as demeaning or reductive of the noble emotions of compassion and generosity. Nor of sexual desire. Sexual desire, when channelled through the conduits of linguistic culture, emerges as great poetry and drama:
John Donne's love poems, say, or Romeo and Juliet. And of course the same thing happens with the misfired redirection of kin- and reciprocation-based compassion. Mercy to a debtor is, when seen out of context, as un-Darwinian as adopting someone else's child:
The quality of mercy is not strained.
It droppeth as the gentle rain from heaven Upon the place beneath.
;
222 i11i <? ^1> I)I-'I. USIC>\
Sexual lust is the driving force behind a large proportion of human ambition and struggle, and much of it constitutes a mis- firing. There is no reason why the same should not be true of the lust to be generous and compassionate, if this is the misfired consequence of ancestral village life. The best way for natural selection to build in both kinds of lust in ancestral times was to install rules of thumb in the brain. Those rules still influence us today, even where circumstances make them inappropriate to their original functions.
Such rules of thumb influence us still, not in a Calvinistically deterministic way but filtered through the civilizing influences of literature and custom, law and tradition - and, of course, religion. Just as the primitive brain rule of sexual lust passes through the filter of civilization to emerge in the love scenes of Romeo and
Juliet, so primitive brain rules of us-versus-them vendetta emerge in the form of the running battles between Capulets and Montagues; while primitive brain rules of altruism and empathy end up in the misfiring that cheers us in the chastened reconciliation of Shakespeare's final scene.
A CASE STUDY IN THE ROOTS OF MORALITY
If our moral sense, like our sexual desire, is indeed rooted deep in our Darwinian past, predating religion, we should expect that research on the human mind would reveal some moral universals, crossing geographical and cultural barriers, and also, crucially, religious barriers. The Harvard biologist Marc Hauser, in his book Moral Minds: How Nature Designed our Universal Sense of Right and Wrong, has enlarged upon a fruitful line of thought experiments originally suggested by moral philosophers. Hauser's study will serve the additional purpose of introducing the way moral philosophers think. A hypothetical moral dilemma is posed, and the difficulty we experience in answering it tells us something about our sense of right and wrong. Where Hauser goes beyond the philosophers is that he actually does statistical surveys and psycho- logical experiments, using questionnaires on the Internet, for
R(>OIS (iI Y1Ol<AIII"I: WI! Y AK! ? ' V\i CiKM)? 223
example, to investigate the moral sense of real people. From the present point of view, the interesting thing is that most people come to the same decisions when faced with these dilemmas, and their agreement over the decisions themselves is stronger than their ability to articulate their reasons. This is what we should expect if we have a moral sense which is built into our brains, like our sexual instinct or our fear of heights or, as Hauser himself prefers to say, like our capacity for language (the details vary from culture to culture, but the underlying deep structure of grammar is universal). As we shall see, the way people respond to these moral tests, and their inability to articulate their reasons, seems largely independent of their religious beliefs or lack of them. The message of Hauser's book, to anticipate it in his own words, is this: 'Driving our moral judgments is a universal moral grammar, a faculty of the mind that evolved over millions of years to include a set of principles for building a range of possible moral systems. As with language, the principles that make up our moral grammar fly beneath the radar of our awareness. '
Typical of Hauser's moral dilemmas are variations on the theme of a runaway truck or 'trolley' on a railway line which threatens to kill a number of people. The simplest story imagines a person, Denise, standing by a set of points and in a position to divert the trolley onto a siding, thereby saving the lives of five people trapped on the main line ahead. Unfortunately there is a man trapped on the siding. But since he is only one, outnumbered by the five people trapped on the main track, most people agree that it is morally permissible, if not obligatory, for Denise to throw the switch and save the five by killing the one. We ignore hypothetical possibilities such as that the one man on the siding might be Beethoven, or a close friend.
Elaborations of the thought experiment present a series of increasingly teasing moral conundrums. What if the trolley can be stopped by dropping a large weight in its path from a bridge over- head? That's easy: obviously we must drop the weight. But what if the only large weight available is a very fat man sitting on the bridge, admiring the sunset? Almost everybody agrees that it is immoral to push the fat man off the bridge, even though, from one point of view, the dilemma might seem parallel to Denise's, where
224 iill <ioi> r-iii:sio. \
throwing the switch kills one to save five. Most of us have a strong intuition that there is a crucial difference between the two cases, though we may not be able to articulate what it is.
Pushing the fat man off the bridge is reminiscent of another dilemma considered by Hauser. Five patients in a hospital are dying, each with a different organ failing. Each would be saved if a donor could be found for their particular faulty organ, but none is available. Then the surgeon notices that there is a healthy man in the waiting-room, all five of whose organs are in good working order and suitable for transplanting. In this case, almost nobody can be found who is prepared to say that the moral act is to kill the one to save the five.
As with the fat man on the bridge, the intuition that most of us share is that an innocent bystander should not suddenly be dragged into a bad situation and used for the sake of others without his consent. Immanuel Kant famously articulated the principle that a rational being should never be used as merely an unconsenting means to an end, even the end of benefiting others. This seems to provide the crucial difference between the case of the fat man on the bridge (or the man in the hospital waiting-room) and the man on Denise's siding. The fat man on the bridge is being positively used as the means to stop the runaway trolley. This clearly violates the Kantian principle. The person on the siding is not being used to save the lives of the five people on the line. It is the siding that is being used, and he just has the bad luck to be standing on it. But, when you put the distinction like that, why does it satisfy us? For Kant, it was a moral absolute. For Hauser it is built into us by our evolution.
The hypothetical situations involving the runaway trolley become increasingly ingenious, and the moral dilemmas corres- pondingly tortuous. Hauser contrasts the dilemmas faced by hypothetical individuals called Ned and Oscar. Ned is standing by the railway track. Unlike Denise, who could divert the trolley onto a siding, Ned's switch diverts it onto a side loop which joins the main track again just before the five people. Simply switching the points doesn't help: the trolley will plough into the five anyway when the diversion rejoins the main track. However, as it happens, there is an extremely fat man on the diversionary track who is
ROt'ils OF MdltAI I'I'V: WHY AttI W1- <,0Ol>? 225
heavy enough to stop the trolley. Should Ned change the points and divert the train? Most people's intuition is that he should not. But what is the difference between Ned's dilemma, and Denise's? Presumably people are intuitively applying Kant's principle. Denise diverts the trolley from ploughing into the five people, and the unfortunate casualty on the siding is 'collateral damage', to use the charmingly Rumsfeldian phrase. He is not being used by Denise to save the others. Ned is actually using the fat man to stop the trolley, and most people (perhaps unthinkingly), along with Kant (thinking it out in great detail), see this as a crucial difference.
The difference is brought out again by the dilemma of Oscar. Oscar's situation is identical to Ned's, except that there is a large iron weight on the diversionary loop of track, heavy enough to stop the trolley. Clearly Oscar should have no problem deciding to pull the points and divert the trolley. Except that there happens to be a hiker walking in front of the iron weight. He will certainly be killed if Oscar pulls the switch, just as surely as Ned's fat man. The difference is that Oscar's hiker is not being used to stop the trolley: he is collateral damage, as in Denise's dilemma. Like Hauser, and like most of Hauser's experimental subjects, I feel that Oscar is permitted to throw the switch but Ned is not. But I also find it quite hard to justify my intuition. Hauser's point is that such moral intuitions are often not well thought out but that we feel them strongly anyway, because of our evolutionary heritage.
In an intriguing venture into anthropology, Hauser and his colleagues adapted their moral experiments to the Kuna, a small Central American tribe with little contact with Westerners and no formal religion. The researchers changed the 'trolley on a line' thought experiment to locally suitable equivalents, such as crocodiles swimming towards canoes. With corresponding minor differences, the Kuna show the same moral judgements as the rest of us.
Of particular interest for this book, Hauser also wondered whether religious people differ from atheists in their moral intuitions. Surely, if we get our morality from religion, they should differ. But it seems that they don't. Hauser, working with the moral
87
philosopher Peter Singer, focused on three hypothetical dilemmas
and compared the verdicts of atheists with those of religious people.
226 1 II K (< O l> I) T i 1 si
In each case, the subjects were asked to choose whether a hypothetical action is morally 'obligatory', 'permissible' or 'forbidden'. The three dilemmas were:
1
2
Denise's dilemma. Ninety per cent of people said it was permissible to divert the trolley, killing the one to save the five.
You see a child drowning in a pond and there is no other help in sight. You can save the child, but your trousers will be ruined in the process. Ninety-seven per cent agreed that you should save the child (amazingly, 3 per cent apparently would prefer to save their trousers).
3 The organ transplant dilemma described above. Ninety-seven per cent of subjects agreed that it is morally forbidden to seize the healthy person in the waiting-room and kill him for his organs, thereby saving five other people.
The main conclusion of Hauser and Singer's study was that there is no statistically significant difference between atheists and religious believers in making these judgements. This seems compatible with the view, which I and many others hold, that we do not need God in order to be good - or evil.
IF THERE IS NO GOD, WHY BE GOOD?
Posed like that, the question sounds positively ignoble. When a religious person puts it to me in this way (and many of them do), my immediate temptation is to issue the following challenge: 'Do you really mean to tell me the only reason you try to be good is to gain God's approval and reward, or to avoid his disapproval and punishment? That's not morality, that's just sucking up, apple- polishing, looking over your shoulder at the great surveillance camera in the sky, or the still small wiretap inside your head, monitoring your every move, even your every base thought. ' As Einstein said, 'If people are good only because they fear punish- ment, and hope for reward, then we are a sorry lot indeed. ' Michael
K O O I S O! M O R A I . I H : <<? II \ \ K Y VM. <;<M>1>? 227
Shermer, in The Science of Good and Evil, calls it a debate stopper. If you agree that, in the absence of God, you would 'commit robbery, rape, and murder', you reveal yourself as an immoral person, 'and we would be well advised to steer a wide course around you'. If, on the other hand, you admit that you would con- tinue to be a good person even when not under divine surveillance, you have fatally undermined your claim that God is necessary for us to be good.
I suspect that quite a lot of religious people do think religion is what motivates them to be good, especially if they belong to one of those faiths that systematically exploits personal guilt.
It seems to me to require quite a low self-regard to think that, should belief in God suddenly vanish from the world, we would all become callous and selfish hedonists, with no kindness, no charity, no generosity, nothing that would deserve the name of goodness. It is widely believed that Dostoevsky was of that opinion, presumably because of some remarks he put into the mouth of Ivan Karamazov:
[Ivanj solemnly observed that there was absolutely no law of nature to make man love humanity, and that if love did exist and had existed at all in the world up to now, then it was not by virtue of the natural law, but entirely because man believed in his own immortality. He added as an aside that it was precisely that which constituted the natural law, namely, that once man's faith in his own immortality was destroyed, not only would his capacity for love be exhausted, but so would the vital forces that sustained life on this earth. And furthermore, nothing would be immoral then, everything would be permitted, even anthropophagy. And finally, as though all this were not enough, he declared that for every individual, such as you and me, for example, who does not believe either in God or in his own immortality, the natural law is bound immediately to become the complete opposite of the religion-based law that preceded it, and that egoism, even extending to the perpetration of crime, would not only be permissible but would be recognized as the essential, the
most rational, and even the noblest raison d'etre of
88
the human condition.
228 'IIi (. Ol! 1)K1USI'? )
Perhaps naively, I have inclined towards a less cynical view of human nature than Ivan Karamazov. Do we really need policing - whether by God or by each other - in order to stop us from behaving in a selfish and criminal manner? I dearly want to believe that I do not need such surveillance - and nor, dear reader, do you. On the other hand, just to weaken our confidence, listen to Steven Pinker's disillusioning experience of a police strike in Montreal, which he describes in The Blank Slate:
As a young teenager in proudly peaceable Canada during the romantic 1960s, I was a true believer in Bakunin's anarchism. I laughed off my parents' argument that if the government ever laid down its arms all hell would break loose. Our competing predictions were put to the test at 8:00 A. M. on October 17, 1969, when the Montreal police went on strike. By 11:20 A. M. the first bank was robbed. By noon most downtown stores had closed because of looting. Within a few more hours, taxi drivers burned down the garage of a limousine service that com- peted with them for airport customers, a rooftop sniper killed a provincial police officer, rioters broke into several hotels and restaurants, and a doctor slew a burglar in his suburban home. By the end of the day, six banks had been robbed, a hundred shops had been looted, twelve fires had been set, forty carloads of storefront glass had been broken, and three million dollars in property damage had been inflicted, before city authorities had to call in the army and, of course, the Mounties to restore order. This decisive empirical test left my politics in tatters . . .
Perhaps I, too, am a Pollyanna to believe that people would remain good when unobserved and unpoliced by God. On the other hand, the majority of the population of Montreal presumably believed in God. Why didn't the fear of God restrain them when earthly police- men were temporarily removed from the scene? Wasn't the Montreal strike a pretty good natural experiment to test the hypothesis that belief in God makes us good? Or did the cynic H. L. Mencken get it right when he tartly observed: 'People say
K O O I S O I V! (> R A 1 1 T Y : W H V A R 1 W 1'. (, O (> 1) ? 229
we need religion when what they really mean is we need police. ' Obviously, not everybody in Montreal behaved badly as soon as the police were off the scene. It would be interesting to know whether there was any statistical tendency, however slight, for religious believers to loot and destroy less than unbelievers. My uninformed prediction would have been opposite. It is often cynically said that there are no atheists in foxholes. I'm inclined to suspect (with some evidence, although it may be simplistic to draw conclusions from it) that there are very few atheists in prisons. I am not necessarily claiming that atheism increases morality, although humanism - the ethical system that often goes with atheism - probably does. Another good possibility is that atheism is correlated with some third factor, such as higher education, intelligence or reflectiveness, which might counteract criminal impulses. Such research evidence as there is certainly doesn't support the common view that religiosity is positively correlated with morality. Correlational evidence is never conclusive, but the following data, described by Sam Harris in his Letter to a Christian
Nation, are nevertheless striking.
While political party affiliation in the United States is not a perfect indicator of religiosity, it is no secret that the 'red [Republican| states' are primarily red due to the over- whelming political influence of conservative Christians. If there were a strong correlation between Christian conser- vatism and societal health, we might expect to see some sign of it in red-state America. We don't. Of the twenty- five cities with the lowest rates of violent crime, 62 percent are in 'blue' [Democrat] states, and 38 percent are in 'red' [Republican] states. Of the twenty-five most dan- gerous cities, 76 percent are in red states, and 24 percent are in blue states. In fact, three of the five most dangerous cities in the U. S. are in the pious state of Texas. The twelve states with the highest rates of burglary are red. Twenty- four of the twenty-nine states with the highest rates of theft are red. Of the twenty-two states with the highest rates of murder, seventeen are red. *
* Note that these colour conventions in America are exactly the opposite of those in Britain, where blue is the colour of the Conservative Party, and red, as in the rest of the world, is the colour traditionally associated with the political left.
230 Mil- (. OP I") r I. I; '? > I O N
Systematic research if anything tends to support such correlational data. Dan Dennett, in Breaking the Spell, sardonically comments, not on Harris's book in particular, but on such studies generally:
Needless to say, these results strike so hard at the standard claims of greater moral virtue among the religious that there has been a considerable surge of further research initiated by religious organizations attempting to refute them . . . one thing we can be sure of is that if there is a significant positive relationship between moral behaviour and religious affiliation, practice, or belief, it will soon be discovered, since so many religious organizations are eager to confirm their traditional beliefs about this scientifically. (They are quite impressed with the truth- finding power of science when it supports what they already believe. ) Every month that passes without such a demonstration underlines the suspicion that it just isn't so.
Most thoughtful people would agree that morality in the absence of policing is somehow more truly moral than the kind of false morality that vanishes as soon as the police go on strike or the spy camera is switched off, whether the spy camera is a real one monitored in the police station or an imaginary one in heaven. But it is perhaps unfair to interpret the question 'If there is no God, why bother to be good? ' in such a cynical way. * A religious thinker could offer a more genuinely moral interpretation, along the lines of the following statement from an imaginary apologist. 'If you don't believe in God, you don't believe there are any absolute standards of morality. With the best will in the world you may intend to be a good person, but how do you decide what is good and what is bad? Only religion can ultimately provide your standards of good and evil. Without religion you have to make it up as you go along. That would be morality without a rule book: morality flying by the seat of its pants. If morality is merely a matter of choice, Hitler could claim to be moral by his own eugenically inspired standards, and all the atheist can do is make a personal choice to live by different lights. The Christian, the Jew or
* H. L. Mencken, again with characteristic cynicism, defined conscience as the inner voice that warns us that someone may be looking.

the Muslim, by contrast, can claim that evil has an absolute mean- ing, true for all time and in all places, according to which Hitler was absolutely evil. '
Even if it were true that we need God to be moral, it would of course not make God's existence more likely, merely more desirable (many people cannot tell the difference). But that is not the issue here. My imaginary religious apologist has no need to admit that sucking up to God is the religious motive for doing good. Rather, his claim is that, wherever the motive to be good comes from, with- out God there would be no standard for deciding what is good. We could each make up our own definition of the good, and behave accordingly. Moral principles that are based only upon religion (as opposed to, say, the 'golden rule', which is often associated with religions but can be derived from elsewhere) may be called absolutist. Good is good and bad is bad, and we don't mess around deciding particular cases by whether, for example, somebody suffers. My religious apologist would claim that only religion can provide a basis for deciding what is good.
Some philosophers, notably Kant, have tried to derive absolute morals from non-religious sources. Though a religious man himself, as was almost inevitable in his time/' Kant tried to base a morality on duty for duty's sake, rather than for God's. His famous categorical imperative enjoins us to 'act only on that maxim whereby thou canst at the same time will that it should become a universal law'. This works tidily for the example of telling lies. Imagine a world in which people told lies as a matter of principle, where lying was regarded as a good and moral thing to do. In such a world, lying itself would cease to have any meaning. Lying needs a presumption of truth for its very definition. If a moral principle is something we should wish everybody to follow, lying cannot be a moral principle because the principle itself would break down in meaninglessness. Lying, as a rule for life, is inherently unstable. More generally, selfishness, or free-riding parasitism on the good- will of others, may work for me as a lone selfish individual and give me personal satisfaction. But I cannot wish that everybody would adopt selfish parasitism as a moral principle, if only because then I would have nobody to parasitize.
* This is the standard interpretation of Kant's views. However, the noted philosopher A. C. Grayling has plausibly argued (New Humanist, July-Aug. 2006) that, although Kant publicly went along with the religious conventions of his time, he was really an atheist.
232 i11r <;o
The Kantian imperative seems to work for truth-telling and some other cases. It is not so easy to see how to broaden it to morality generally. Kant notwithstanding, it is tempting to agree with my hypothetical apologist that absolutist morals are usually driven by religion. Is it always wrong to put a terminally ill patient out of her misery at her own request? Is it always wrong to make love to a member of your own sex? Is it always wrong to kill an embryo? There are those who believe so, and their grounds are absolute. They brook no argument or debate. Anybody who disagrees deserves to be shot: metaphorically of course, not literally - except in the case of some doctors in American abortion clinics (see next chapter). Fortunately, however, morals do not have to be absolute.
Moral philosophers are the professionals when it comes to thinking about right and wrong. As Robert Hinde succinctly put it, they agree that 'moral precepts, while not necessarily constructed
89
by reason, should be defensible by reason'.
selves in many ways, but in modern terminology the major divide is between 'deontologists' (such as Kant) and 'consequentialists' (including 'utilitarians' such as Jeremy Bentham, 1748-1832). Deontology is a fancy name for the belief that morality consists in the obeying of rules. It is literally the science of duty, from the Greek for 'that which is binding'. Deontology is not quite the same thing as moral absolutism, but for most purposes in a book about religion there is no need to dwell on the distinction. Absolutists believe there are absolutes of right and wrong, imperatives whose Tightness makes no reference to their consequences. Consequentialists more pragmatically hold that the morality of an action should be judged by its consequences. One version of consequentialism is utilitarianism, the philosophy associated with Bentham, his friend James Mill (1773-1836) and Mill's son John Stuart Mill (1806-73). Utilitarianism is often summed up in Bentham's unfortunately imprecise catchphrase: 'the greatest happiness of the greatest number is the foundation of morals and legislation'.
Not all absolutism is derived from religion. Nevertheless, it is pretty hard to defend absolutist morals on grounds other than religious ones. The only competitor I can think of is patriotism, especially in times of war. As the distinguished Spanish film director

Luis Bunuel said, 'God and Country are an unbeatable team; they break all records for oppression and bloodshed. ' Recruiting officers rely heavily on their victims' sense of patriotic duty. In the First World War, women handed out white feathers to young men not in uniform.
Oh, we don't want to lose you, but we think you ought to go, For your King and your country both need you so.
People despised conscientious objectors, even those of the enemy country, because patriotism was held to be an absolute virtue. It is hard to get much more absolute than the 'My country right or wrong' of the professional soldier, for the slogan commits you to kill whomever the politicians of some future date might choose to call enemies. Consequentialist reasoning may influence the polit- ical decision to go to war but, once war is declared, absolutist patriotism takes over with a force and a power not otherwise seen outside religion. A soldier who allows his own thoughts of consequentialist morality to persuade him not to go over the top would likely find himself court-martialled and even executed.
The springboard for this discussion of moral philosophy was a hypothetical religious claim that, without a God, morals are relative and arbitrary. Kant and. other sophisticated moral philosophers apart, and with due recognition given to patriotic fervour, the preferred source of absolute morality is usually a holy book of some kind, interpreted as having an authority far beyond its history's capacity to justify. Indeed, adherents of scriptural authority show distressingly little curiosity about the (normally highly dubious) historical origins of their holy books. The next chapter will demonstrate that, in any case, people who claim to derive their morals from scripture do not really do so in practice. And a very good thing too, as they themselves, on reflection, should agree.

There are two ways in which scripture might be a source of morals or rules for living. One is by direct instruction, for example through the Ten Commandments, which are the subject of such bitter contention in the culture wars of America's boondocks. The other is by example: God, or some other biblical character, might serve as - to use the contemporary jargon - a role model. Both scriptural routes, if followed through religiously (the adverb is used in its metaphoric sense but with an eye to its origin), encourage a system of morals which any civilized modern person, whether religious or not, would find - I can put it no more gently - obnoxious.
To be fair, much of the Bible is not systematically evil but just plain weird, as you would expect of a chaotically cobbled-together anthology of disjointed documents, composed, revised, translated, distorted and 'improved' by hundreds of anonymous authors, editors and copyists, unknown to us and mostly unknown to each

strangeness of the Bible. But unfortunately it is this same weird volume that religious zealots hold up to us as the inerrant source of our morals and rules for living. Those who wish to base their morality literally on the Bible have either not read it or not under- stood it, as Bishop John Shelby Spong, in The Sins of Scripture, rightly observed. Bishop Spong, by the way, is a nice example of a liberal bishop whose beliefs are so advanced as to be almost un- recognizable to the majority of those who call themselves Christians. A British counterpart is Richard Holloway, recently retired as Bishop of Edinburgh. Bishop Holloway even describes himself as a 'recovering Christian'. I had a public discussion with him in Edinburgh, which was one of the most stimulating and

THE OLD TESTAMENT
Begin in Genesis with the well-loved story of Noah, derived from the Babylonian myth of Uta-Napisthim and known from the older mythologies of several cultures. The legend of the animals going into the ark two by two is charming, but the moral of the story of
This may explain some of the sheer
238 T H F G O D D E L U S I O N
Noah is appalling. God took a dim view of humans, so he (with the exception of one family) drowned the lot of them including children and also, for good measure, the rest of the (presumably blameless) animals as well.
Of course, irritated theologians will protest that we don't take the book of Genesis literally any more. But that is my whole point! We pick and choose which bits of scripture to believe, which bits to write off as symbols or allegories. Such picking and choosing is a matter of personal decision, just as much, or as little, as the atheist's decision to follow this moral precept or that was a personal decision, without an absolute foundation. If one of these is 'morality flying by the seat of its pants', so is the other.
In any case, despite the good intentions of the sophisticated theologian, a frighteningly large number of people still do take their scriptures, including the story of Noah, literally. According to Gallup, they include approximately 50 per cent of the US elec- torate. Also, no doubt, many of those Asian holy men who blamed
92 the 2004 tsunami not on a plate tectonic shift but on human sins,
ranging from drinking and dancing in bars to breaking some footling sabbath rule. Steeped in the story of Noah, and ignorant of all except biblical learning, who can blame them? Their whole edu- cation has led them to view natural disasters as bound up with human affairs, paybacks for human misdemeanours rather than anything so impersonal as plate tectonics. By the way, what pre- sumptuous egocentricity to believe that earth-shaking events, on the scale at which a god (or a tectonic plate) might operate, must always have a human connection. Why should a divine being, with creation and eternity on his mind, care a fig for petty human male- factions? We humans give ourselves such airs, even aggrandizing our poky little 'sins' to the level of cosmic significance!
When I interviewed for television the Reverend Michael Bray, a prominent American anti-abortion activist, I asked him why evangelical Christians were so obsessed with private sexual inclin- ations such as homosexuality, which didn't interfere with anybody else's life. His reply invoked something like self-defence. Innocent citizens are at risk of becoming collateral damage when God chooses to strike a town with a natural disaster because it houses sinners. In 2005, the fine city of New Orleans was catastrophically
T H E ' G O O D ' B O O K A N D T H E M O R A L Z ? 1 T G E I S T 239
flooded in the aftermath of a hurricane, Katrina. The Reverend Pat Robertson, one of America's best-known televangelists and a former presidential candidate, was reported as blaming the hurricane on a lesbian comedian who happened to live in New Orleans. * You'd think an omnipotent God would adopt a slightly more targeted approach to zapping sinners: a judicious heart attack, perhaps, rather than the wholesale destruction of an entire city just because it happened to be the domicile of one lesbian comedian.
In November 2005, the citizens of Dover, Pennsylvania voted off their local school board the entire slate of fundamentalists who had brought the town notoriety, not to say ridicule, by attempting to enforce the teaching of 'intelligent design'. When Pat Robertson heard that the fundamentalists had been democratically defeated at the ballot, he offered a stern warning to Dover:
I'd like to say to the good citizens of Dover, if there is a disaster in your area, don't turn to God. You just rejected him from your city, and don't wonder why he hasn't helped you when problems begin, if they begin, and I'm not saying they will. But if they do, just remember you just voted God out of your city. And if that's the case, then

Pat Robertson would be harmless comedy, were he less typical of those who today hold power and influence in the United States.
In the destruction of Sodom and Gomorrah, the Noah equivalent, chosen to be spared with his family because he was uniquely righteous, was Abraham's nephew Lot. Two male angels were sent to Sodom to warn Lot to leave the city before the brim- stone arrived.

when their turn comes.
For there will always be cheats, and stable solutions to the game-
theoretic conundrums of reciprocal altruism always involve an element of punishment of cheats. Mathematical theory allows two broad classes of stable solution to 'games' of this kind. 'Always be nasty' is stable in that, if everybody else is doing it, a single nice individual cannot do better. But there is another strategy which is also stable. ('Stable' means that, once it exceeds a critical frequency in the population, no alternative does better. ) This is the strategy, 'Start out being nice, and give others the benefit of the doubt. Then
218 T H E Ci O D I) E I. U S I O N
repay good deeds with good, but avenge bad deeds. ' In game theory language, this strategy (or family of related strategies) goes under various names, including Tit-for-Tat, Retaliator and Reciprocator. It is evolutionarily stable under some conditions in the sense that, given a population dominated by reciprocators, no single nasty individual, and no single unconditionally nice individual, will do better. There are other, more complicated variants of Tit-for-Tat which can in some circumstances do better.
I have mentioned kinship and reciprocation as the twin pillars of altruism in a Darwinian world, but there are secondary structures which rest atop those main pillars. Especially in human society, with language and gossip, reputation is important. One individual may have a reputation for kindness and generosity. Another individual may have a reputation for unreliability, for cheating and reneging on deals. Another may have a reputation for generosity when trust has been built up, but for ruthless punishment of cheat- ing. The unadorned theory of reciprocal altruism expects animals of any species to base their behaviour upon unconscious responsiveness to such traits in their fellows. In human societies we add the power of language to spread reputations, usually in the form of gossip. You don't need to have suffered personally from X's failure to buy his round at the pub. You hear 'on the grapevine' that X is a tightwad, or - to add an ironic complication to the example - that Y is a terrible gossip. Reputation is important, and biologists can acknowledge a Darwinian survival value in not just being a good reciprocator but fostering a reputation as a good reciprocator too. Matt Ridley's The Origins of Virtue, as well as being a lucid account of the whole field of Darwinian morality, is especially good on reputation. *
The Norwegian economist Thorstein Veblen and, in a rather different way, the Israeli zoologist Amotz Zahavi have added a further fascinating idea. Altruistic giving may be an advertisement of dominance or superiority. Anthropologists know it as the Potlatch Effect, named after the custom whereby rival chieftains of
* Reputation is not confined to humans. It has recently been shown to apply to one of the classic cases of reciprocal altruism in animals, the symbiotic relation- ship between small cleaner fish and their large fish clients. In an ingenious experiment, individual cleaner wrasse, Labroides dimidiatus, that had been observed by a would-be client to be diligent cleaners were more likely to be cho- sen by the client than rival Labroides that had been observed neglecting to clean. See R. Bshary and A. S. Grutter, 'Image scoring and cooperation in a cleaner fish mutualism', Nature 441, 22 June 2006, 975-8.
THF, ROOTS OF MORALI TY: WHY ARE WE GOOD? 219
Pacific north-west tribes vie with each other in duels of ruinously generous feasts. In extreme cases, bouts of retaliatory entertaining continue until one side is reduced to penury, leaving the winner not much better off. Veblen's concept of 'conspicuous consumption' strikes a chord with many observers of the modern scene. Zahavi's contribution, unregarded by biologists for many years until vindicated by brilliant mathematical models from the theorist Alan Grafen, has been to provide an evolutionary version of the potlatch idea. Zahavi studies Arabian babblers, little brown birds who live in social groups and breed co-operatively. Like many small birds, babblers give warning cries, and they also donate food to each other. A standard Darwinian investigation of such altruistic acts would look, first, for reciprocation and kinship relationships
among the birds. When a babbler feeds a companion, is it in the expectation of being fed at a later date? Or is the recipient of the favour a close genetic relative? Zahavi's interpretation is radically unexpected. Dominant babblers assert their dominance by feeding subordinates. To use the sort of anthropomorphic language Zahavi delights in, the dominant bird is saying the equivalent of, 'Look how superior I am to you, I can afford to give you food. ' Or 'Look how superior I am, I can afford to make myself vulnerable to hawks by sitting on a high branch, acting as a sentinel to warn the rest of the flock feeding on the ground. ' The observations of Zahavi and his colleagues suggest that babblers actively compete for the dangerous role of sentinel. And when a subordinate babbler attempts to offer food to a dominant individual, the apparent generosity is violently rebuffed. The essence of Zahavi's idea is that advertisements of superiority are authenticated by their cost. Only a genuinely superior individual can afford to advertise the fact by means of a costly gift. Individuals buy success, for example in attracting mates, through costly demonstrations of superiority, including ostentatious generosity and public-spirited risk-taking.
We now have four good Darwinian reasons for individuals to be altruistic, generous or 'moral' towards each other. First, there is the special case of genetic kinship. Second, there is reciprocation: the repayment of favours given, and the giving of favours in 'anticipation' of payback. Following on from this there is, third, the Darwinian benefit of acquiring a reputation for generosity and
220 i H r o o i> i) hi (i s i o N
kindness. And fourth, if Zahavi is right, there is the particular additional benefit of conspicuous generosity as a way of buying unfakeably authentic advertising.
Through most of our prehistory, humans lived under conditions that would have strongly favoured the evolution of all four kinds of altruism. We lived in villages, or earlier in discrete roving bands like baboons, partially isolated from neighbouring bands or villages. Most of your fellow band members would have been kin, more closely related to you than members of other bands - plenty of opportunities for kin altruism to evolve. And, whether kin or not, you would tend to meet the same individuals again and again throughout your life - ideal conditions for the evolution of reciprocal altruism. Those are also the ideal conditions for building a reputation for altruism, and the very same ideal conditions for advertising conspicuous generosity. By any or all of the four routes, genetic tendencies towards altruism would have been favoured in early humans. It is easy to see why our prehistoric ancestors would have been good to their own in-group but bad - to the point of xenophobia - towards other groups. But why - now that most of us live in big cities where we are no longer surrounded by kin, and where every day we meet individuals whom we are never going to meet again -- why are we still so good to each other, even some- times to others who might be thought to belong to an out-group?
It is important not to mis-state the reach of natural selection. Selection does not favour the evolution of a cognitive awareness of what is good for your genes. That awareness had to wait for the twentieth century to reach a cognitive level, and even now full understanding is confined to a minority of scientific specialists. What natural selection favours is rules of thumb, which work in practice to promote the genes that built them. Rules of thumb, by their nature, sometimes misfire. In a bird's brain, the rule 'Look after small squawking things in your nest, and drop food into their red gapes' typically has the effect of preserving the genes that built the rule, because the squawking, gaping objects in an adult bird's nest are normally its own offspring. The rule misfires if another baby bird somehow gets into the nest, a circumstance that is positively engineered by cuckoos. Could it be that our Good Samaritan urges are misfirings, analogous to the misfiring of a reed
\ I i ' ) K A I I M : \ V 1 ! \ A i d S I t , t ' ' i i i ) '? 221
warbler's parental instincts when it works itself to the bone for a young cuckoo? An even closer analogy is the human urge to adopt a child. I must rush to add that 'misfiring' is intended only in a strictly Darwinian sense. It carries no suggestion of the pejorative.
The 'mistake' or 'by-product' idea, which I am espousing, works like this. Natural selection, in ancestral times when we lived in small and stable bands like baboons, programmed into our brains altruistic urges, alongside sexual urges, hunger urges, xenophobic urges and so on. An intelligent couple can read their Darwin and know that the ultimate reason for their sexual urges is procreation. They know that the woman cannot conceive because she is on the pill. Yet they find that their sexual desire is in no way diminished by the knowledge. Sexual desire is sexual desire and its force, in an individual's psychology, is independent of the ultimate Darwinian pressure that drove it. It is a strong urge which exists independently of its ultimate rationale.
I am suggesting that the same is true of the urge to kindness - to altruism, to generosity, to empathy, to pity. In ancestral times, we had the opportunity to be altruistic only towards close kin and potential reciprocators. Nowadays that restriction is no longer there, but the rule of thumb persists. Why would it not? It is just like sexual desire. We can no more help ourselves feeling pity when we see a weeping unfortunate (who is unrelated and unable to reciprocate) than we can help ourselves feeling lust for a member of the opposite sex (who may be infertile or otherwise unable to reproduce). Both are misfirings, Darwinian mistakes: blessed, precious mistakes.
Do not, for one moment, think of such Darwinizing as demeaning or reductive of the noble emotions of compassion and generosity. Nor of sexual desire. Sexual desire, when channelled through the conduits of linguistic culture, emerges as great poetry and drama:
John Donne's love poems, say, or Romeo and Juliet. And of course the same thing happens with the misfired redirection of kin- and reciprocation-based compassion. Mercy to a debtor is, when seen out of context, as un-Darwinian as adopting someone else's child:
The quality of mercy is not strained.
It droppeth as the gentle rain from heaven Upon the place beneath.
;
222 i11i <? ^1> I)I-'I. USIC>\
Sexual lust is the driving force behind a large proportion of human ambition and struggle, and much of it constitutes a mis- firing. There is no reason why the same should not be true of the lust to be generous and compassionate, if this is the misfired consequence of ancestral village life. The best way for natural selection to build in both kinds of lust in ancestral times was to install rules of thumb in the brain. Those rules still influence us today, even where circumstances make them inappropriate to their original functions.
Such rules of thumb influence us still, not in a Calvinistically deterministic way but filtered through the civilizing influences of literature and custom, law and tradition - and, of course, religion. Just as the primitive brain rule of sexual lust passes through the filter of civilization to emerge in the love scenes of Romeo and
Juliet, so primitive brain rules of us-versus-them vendetta emerge in the form of the running battles between Capulets and Montagues; while primitive brain rules of altruism and empathy end up in the misfiring that cheers us in the chastened reconciliation of Shakespeare's final scene.
A CASE STUDY IN THE ROOTS OF MORALITY
If our moral sense, like our sexual desire, is indeed rooted deep in our Darwinian past, predating religion, we should expect that research on the human mind would reveal some moral universals, crossing geographical and cultural barriers, and also, crucially, religious barriers. The Harvard biologist Marc Hauser, in his book Moral Minds: How Nature Designed our Universal Sense of Right and Wrong, has enlarged upon a fruitful line of thought experiments originally suggested by moral philosophers. Hauser's study will serve the additional purpose of introducing the way moral philosophers think. A hypothetical moral dilemma is posed, and the difficulty we experience in answering it tells us something about our sense of right and wrong. Where Hauser goes beyond the philosophers is that he actually does statistical surveys and psycho- logical experiments, using questionnaires on the Internet, for
R(>OIS (iI Y1Ol<AIII"I: WI! Y AK! ? ' V\i CiKM)? 223
example, to investigate the moral sense of real people. From the present point of view, the interesting thing is that most people come to the same decisions when faced with these dilemmas, and their agreement over the decisions themselves is stronger than their ability to articulate their reasons. This is what we should expect if we have a moral sense which is built into our brains, like our sexual instinct or our fear of heights or, as Hauser himself prefers to say, like our capacity for language (the details vary from culture to culture, but the underlying deep structure of grammar is universal). As we shall see, the way people respond to these moral tests, and their inability to articulate their reasons, seems largely independent of their religious beliefs or lack of them. The message of Hauser's book, to anticipate it in his own words, is this: 'Driving our moral judgments is a universal moral grammar, a faculty of the mind that evolved over millions of years to include a set of principles for building a range of possible moral systems. As with language, the principles that make up our moral grammar fly beneath the radar of our awareness. '
Typical of Hauser's moral dilemmas are variations on the theme of a runaway truck or 'trolley' on a railway line which threatens to kill a number of people. The simplest story imagines a person, Denise, standing by a set of points and in a position to divert the trolley onto a siding, thereby saving the lives of five people trapped on the main line ahead. Unfortunately there is a man trapped on the siding. But since he is only one, outnumbered by the five people trapped on the main track, most people agree that it is morally permissible, if not obligatory, for Denise to throw the switch and save the five by killing the one. We ignore hypothetical possibilities such as that the one man on the siding might be Beethoven, or a close friend.
Elaborations of the thought experiment present a series of increasingly teasing moral conundrums. What if the trolley can be stopped by dropping a large weight in its path from a bridge over- head? That's easy: obviously we must drop the weight. But what if the only large weight available is a very fat man sitting on the bridge, admiring the sunset? Almost everybody agrees that it is immoral to push the fat man off the bridge, even though, from one point of view, the dilemma might seem parallel to Denise's, where
224 iill <ioi> r-iii:sio. \
throwing the switch kills one to save five. Most of us have a strong intuition that there is a crucial difference between the two cases, though we may not be able to articulate what it is.
Pushing the fat man off the bridge is reminiscent of another dilemma considered by Hauser. Five patients in a hospital are dying, each with a different organ failing. Each would be saved if a donor could be found for their particular faulty organ, but none is available. Then the surgeon notices that there is a healthy man in the waiting-room, all five of whose organs are in good working order and suitable for transplanting. In this case, almost nobody can be found who is prepared to say that the moral act is to kill the one to save the five.
As with the fat man on the bridge, the intuition that most of us share is that an innocent bystander should not suddenly be dragged into a bad situation and used for the sake of others without his consent. Immanuel Kant famously articulated the principle that a rational being should never be used as merely an unconsenting means to an end, even the end of benefiting others. This seems to provide the crucial difference between the case of the fat man on the bridge (or the man in the hospital waiting-room) and the man on Denise's siding. The fat man on the bridge is being positively used as the means to stop the runaway trolley. This clearly violates the Kantian principle. The person on the siding is not being used to save the lives of the five people on the line. It is the siding that is being used, and he just has the bad luck to be standing on it. But, when you put the distinction like that, why does it satisfy us? For Kant, it was a moral absolute. For Hauser it is built into us by our evolution.
The hypothetical situations involving the runaway trolley become increasingly ingenious, and the moral dilemmas corres- pondingly tortuous. Hauser contrasts the dilemmas faced by hypothetical individuals called Ned and Oscar. Ned is standing by the railway track. Unlike Denise, who could divert the trolley onto a siding, Ned's switch diverts it onto a side loop which joins the main track again just before the five people. Simply switching the points doesn't help: the trolley will plough into the five anyway when the diversion rejoins the main track. However, as it happens, there is an extremely fat man on the diversionary track who is
ROt'ils OF MdltAI I'I'V: WHY AttI W1- <,0Ol>? 225
heavy enough to stop the trolley. Should Ned change the points and divert the train? Most people's intuition is that he should not. But what is the difference between Ned's dilemma, and Denise's? Presumably people are intuitively applying Kant's principle. Denise diverts the trolley from ploughing into the five people, and the unfortunate casualty on the siding is 'collateral damage', to use the charmingly Rumsfeldian phrase. He is not being used by Denise to save the others. Ned is actually using the fat man to stop the trolley, and most people (perhaps unthinkingly), along with Kant (thinking it out in great detail), see this as a crucial difference.
The difference is brought out again by the dilemma of Oscar. Oscar's situation is identical to Ned's, except that there is a large iron weight on the diversionary loop of track, heavy enough to stop the trolley. Clearly Oscar should have no problem deciding to pull the points and divert the trolley. Except that there happens to be a hiker walking in front of the iron weight. He will certainly be killed if Oscar pulls the switch, just as surely as Ned's fat man. The difference is that Oscar's hiker is not being used to stop the trolley: he is collateral damage, as in Denise's dilemma. Like Hauser, and like most of Hauser's experimental subjects, I feel that Oscar is permitted to throw the switch but Ned is not. But I also find it quite hard to justify my intuition. Hauser's point is that such moral intuitions are often not well thought out but that we feel them strongly anyway, because of our evolutionary heritage.
In an intriguing venture into anthropology, Hauser and his colleagues adapted their moral experiments to the Kuna, a small Central American tribe with little contact with Westerners and no formal religion. The researchers changed the 'trolley on a line' thought experiment to locally suitable equivalents, such as crocodiles swimming towards canoes. With corresponding minor differences, the Kuna show the same moral judgements as the rest of us.
Of particular interest for this book, Hauser also wondered whether religious people differ from atheists in their moral intuitions. Surely, if we get our morality from religion, they should differ. But it seems that they don't. Hauser, working with the moral
87
philosopher Peter Singer, focused on three hypothetical dilemmas
and compared the verdicts of atheists with those of religious people.
226 1 II K (< O l> I) T i 1 si
In each case, the subjects were asked to choose whether a hypothetical action is morally 'obligatory', 'permissible' or 'forbidden'. The three dilemmas were:
1
2
Denise's dilemma. Ninety per cent of people said it was permissible to divert the trolley, killing the one to save the five.
You see a child drowning in a pond and there is no other help in sight. You can save the child, but your trousers will be ruined in the process. Ninety-seven per cent agreed that you should save the child (amazingly, 3 per cent apparently would prefer to save their trousers).
3 The organ transplant dilemma described above. Ninety-seven per cent of subjects agreed that it is morally forbidden to seize the healthy person in the waiting-room and kill him for his organs, thereby saving five other people.
The main conclusion of Hauser and Singer's study was that there is no statistically significant difference between atheists and religious believers in making these judgements. This seems compatible with the view, which I and many others hold, that we do not need God in order to be good - or evil.
IF THERE IS NO GOD, WHY BE GOOD?
Posed like that, the question sounds positively ignoble. When a religious person puts it to me in this way (and many of them do), my immediate temptation is to issue the following challenge: 'Do you really mean to tell me the only reason you try to be good is to gain God's approval and reward, or to avoid his disapproval and punishment? That's not morality, that's just sucking up, apple- polishing, looking over your shoulder at the great surveillance camera in the sky, or the still small wiretap inside your head, monitoring your every move, even your every base thought. ' As Einstein said, 'If people are good only because they fear punish- ment, and hope for reward, then we are a sorry lot indeed. ' Michael
K O O I S O! M O R A I . I H : <<? II \ \ K Y VM. <;<M>1>? 227
Shermer, in The Science of Good and Evil, calls it a debate stopper. If you agree that, in the absence of God, you would 'commit robbery, rape, and murder', you reveal yourself as an immoral person, 'and we would be well advised to steer a wide course around you'. If, on the other hand, you admit that you would con- tinue to be a good person even when not under divine surveillance, you have fatally undermined your claim that God is necessary for us to be good.
I suspect that quite a lot of religious people do think religion is what motivates them to be good, especially if they belong to one of those faiths that systematically exploits personal guilt.
It seems to me to require quite a low self-regard to think that, should belief in God suddenly vanish from the world, we would all become callous and selfish hedonists, with no kindness, no charity, no generosity, nothing that would deserve the name of goodness. It is widely believed that Dostoevsky was of that opinion, presumably because of some remarks he put into the mouth of Ivan Karamazov:
[Ivanj solemnly observed that there was absolutely no law of nature to make man love humanity, and that if love did exist and had existed at all in the world up to now, then it was not by virtue of the natural law, but entirely because man believed in his own immortality. He added as an aside that it was precisely that which constituted the natural law, namely, that once man's faith in his own immortality was destroyed, not only would his capacity for love be exhausted, but so would the vital forces that sustained life on this earth. And furthermore, nothing would be immoral then, everything would be permitted, even anthropophagy. And finally, as though all this were not enough, he declared that for every individual, such as you and me, for example, who does not believe either in God or in his own immortality, the natural law is bound immediately to become the complete opposite of the religion-based law that preceded it, and that egoism, even extending to the perpetration of crime, would not only be permissible but would be recognized as the essential, the
most rational, and even the noblest raison d'etre of
88
the human condition.
228 'IIi (. Ol! 1)K1USI'? )
Perhaps naively, I have inclined towards a less cynical view of human nature than Ivan Karamazov. Do we really need policing - whether by God or by each other - in order to stop us from behaving in a selfish and criminal manner? I dearly want to believe that I do not need such surveillance - and nor, dear reader, do you. On the other hand, just to weaken our confidence, listen to Steven Pinker's disillusioning experience of a police strike in Montreal, which he describes in The Blank Slate:
As a young teenager in proudly peaceable Canada during the romantic 1960s, I was a true believer in Bakunin's anarchism. I laughed off my parents' argument that if the government ever laid down its arms all hell would break loose. Our competing predictions were put to the test at 8:00 A. M. on October 17, 1969, when the Montreal police went on strike. By 11:20 A. M. the first bank was robbed. By noon most downtown stores had closed because of looting. Within a few more hours, taxi drivers burned down the garage of a limousine service that com- peted with them for airport customers, a rooftop sniper killed a provincial police officer, rioters broke into several hotels and restaurants, and a doctor slew a burglar in his suburban home. By the end of the day, six banks had been robbed, a hundred shops had been looted, twelve fires had been set, forty carloads of storefront glass had been broken, and three million dollars in property damage had been inflicted, before city authorities had to call in the army and, of course, the Mounties to restore order. This decisive empirical test left my politics in tatters . . .
Perhaps I, too, am a Pollyanna to believe that people would remain good when unobserved and unpoliced by God. On the other hand, the majority of the population of Montreal presumably believed in God. Why didn't the fear of God restrain them when earthly police- men were temporarily removed from the scene? Wasn't the Montreal strike a pretty good natural experiment to test the hypothesis that belief in God makes us good? Or did the cynic H. L. Mencken get it right when he tartly observed: 'People say
K O O I S O I V! (> R A 1 1 T Y : W H V A R 1 W 1'. (, O (> 1) ? 229
we need religion when what they really mean is we need police. ' Obviously, not everybody in Montreal behaved badly as soon as the police were off the scene. It would be interesting to know whether there was any statistical tendency, however slight, for religious believers to loot and destroy less than unbelievers. My uninformed prediction would have been opposite. It is often cynically said that there are no atheists in foxholes. I'm inclined to suspect (with some evidence, although it may be simplistic to draw conclusions from it) that there are very few atheists in prisons. I am not necessarily claiming that atheism increases morality, although humanism - the ethical system that often goes with atheism - probably does. Another good possibility is that atheism is correlated with some third factor, such as higher education, intelligence or reflectiveness, which might counteract criminal impulses. Such research evidence as there is certainly doesn't support the common view that religiosity is positively correlated with morality. Correlational evidence is never conclusive, but the following data, described by Sam Harris in his Letter to a Christian
Nation, are nevertheless striking.
While political party affiliation in the United States is not a perfect indicator of religiosity, it is no secret that the 'red [Republican| states' are primarily red due to the over- whelming political influence of conservative Christians. If there were a strong correlation between Christian conser- vatism and societal health, we might expect to see some sign of it in red-state America. We don't. Of the twenty- five cities with the lowest rates of violent crime, 62 percent are in 'blue' [Democrat] states, and 38 percent are in 'red' [Republican] states. Of the twenty-five most dan- gerous cities, 76 percent are in red states, and 24 percent are in blue states. In fact, three of the five most dangerous cities in the U. S. are in the pious state of Texas. The twelve states with the highest rates of burglary are red. Twenty- four of the twenty-nine states with the highest rates of theft are red. Of the twenty-two states with the highest rates of murder, seventeen are red. *
* Note that these colour conventions in America are exactly the opposite of those in Britain, where blue is the colour of the Conservative Party, and red, as in the rest of the world, is the colour traditionally associated with the political left.

Systematic research if anything tends to support such correlational data. Dan Dennett, in Breaking the Spell, sardonically comments, not on Harris's book in particular, but on such studies generally:
Needless to say, these results strike so hard at the standard claims of greater moral virtue among the religious that there has been a considerable surge of further research initiated by religious organizations attempting to refute them . . . one thing we can be sure of is that if there is a significant positive relationship between moral behaviour and religious affiliation, practice, or belief, it will soon be discovered, since so many religious organizations are eager to confirm their traditional beliefs about this scientifically. (They are quite impressed with the truth- finding power of science when it supports what they already believe. ) Every month that passes without such a demonstration underlines the suspicion that it just isn't so.
Most thoughtful people would agree that morality in the absence of policing is somehow more truly moral than the kind of false morality that vanishes as soon as the police go on strike or the spy camera is switched off, whether the spy camera is a real one monitored in the police station or an imaginary one in heaven. But it is perhaps unfair to interpret the question 'If there is no God, why bother to be good? ' in such a cynical way. * A religious thinker could offer a more genuinely moral interpretation, along the lines of the following statement from an imaginary apologist. 'If you don't believe in God, you don't believe there are any absolute standards of morality. With the best will in the world you may intend to be a good person, but how do you decide what is good and what is bad? Only religion can ultimately provide your standards of good and evil. Without religion you have to make it up as you go along. That would be morality without a rule book: morality flying by the seat of its pants. If morality is merely a matter of choice, Hitler could claim to be moral by his own eugenically inspired standards, and all the atheist can do is make a personal choice to live by different lights. The Christian, the Jew or
* H. L. Mencken, again with characteristic cynicism, defined conscience as the inner voice that warns us that someone may be looking.

the Muslim, by contrast, can claim that evil has an absolute mean- ing, true for all time and in all places, according to which Hitler was absolutely evil. '
Even if it were true that we need God to be moral, it would of course not make God's existence more likely, merely more desirable (many people cannot tell the difference). But that is not the issue here. My imaginary religious apologist has no need to admit that sucking up to God is the religious motive for doing good. Rather, his claim is that, wherever the motive to be good comes from, with- out God there would be no standard for deciding what is good. We could each make up our own definition of the good, and behave accordingly. Moral principles that are based only upon religion (as opposed to, say, the 'golden rule', which is often associated with religions but can be derived from elsewhere) may be called absolutist. Good is good and bad is bad, and we don't mess around deciding particular cases by whether, for example, somebody suffers. My religious apologist would claim that only religion can provide a basis for deciding what is good.
Some philosophers, notably Kant, have tried to derive absolute morals from non-religious sources. Though a religious man himself, as was almost inevitable in his time/' Kant tried to base a morality on duty for duty's sake, rather than for God's. His famous categorical imperative enjoins us to 'act only on that maxim whereby thou canst at the same time will that it should become a universal law'. This works tidily for the example of telling lies. Imagine a world in which people told lies as a matter of principle, where lying was regarded as a good and moral thing to do. In such a world, lying itself would cease to have any meaning. Lying needs a presumption of truth for its very definition. If a moral principle is something we should wish everybody to follow, lying cannot be a moral principle because the principle itself would break down in meaninglessness. Lying, as a rule for life, is inherently unstable. More generally, selfishness, or free-riding parasitism on the good- will of others, may work for me as a lone selfish individual and give me personal satisfaction. But I cannot wish that everybody would adopt selfish parasitism as a moral principle, if only because then I would have nobody to parasitize.
* This is the standard interpretation of Kant's views. However, the noted philosopher A. C. Grayling has plausibly argued (New Humanist, July-Aug. 2006) that, although Kant publicly went along with the religious conventions of his time, he was really an atheist.

The Kantian imperative seems to work for truth-telling and some other cases. It is not so easy to see how to broaden it to morality generally. Kant notwithstanding, it is tempting to agree with my hypothetical apologist that absolutist morals are usually driven by religion. Is it always wrong to put a terminally ill patient out of her misery at her own request? Is it always wrong to make love to a member of your own sex? Is it always wrong to kill an embryo? There are those who believe so, and their grounds are absolute. They brook no argument or debate. Anybody who disagrees deserves to be shot: metaphorically of course, not literally - except in the case of some doctors in American abortion clinics (see next chapter). Fortunately, however, morals do not have to be absolute.
Moral philosophers are the professionals when it comes to thinking about right and wrong. As Robert Hinde succinctly put it, they agree that 'moral precepts, while not necessarily constructed

by reason, should be defensible by reason'.
selves in many ways, but in modern terminology the major divide is between 'deontologists' (such as Kant) and 'consequentialists' (including 'utilitarians' such as Jeremy Bentham, 1748-1832). Deontology is a fancy name for the belief that morality consists in the obeying of rules. It is literally the science of duty, from the Greek for 'that which is binding'. Deontology is not quite the same thing as moral absolutism, but for most purposes in a book about religion there is no need to dwell on the distinction. Absolutists believe there are absolutes of right and wrong, imperatives whose Tightness makes no reference to their consequences. Consequentialists more pragmatically hold that the morality of an action should be judged by its consequences. One version of consequentialism is utilitarianism, the philosophy associated with Bentham, his friend James Mill (1773-1836) and Mill's son John Stuart Mill (1806-73). Utilitarianism is often summed up in Bentham's unfortunately imprecise catchphrase: 'the greatest happiness of the greatest number is the foundation of morals and legislation'.
Not all absolutism is derived from religion. Nevertheless, it is pretty hard to defend absolutist morals on grounds other than religious ones. The only competitor I can think of is patriotism, especially in times of war. As the distinguished Spanish film director

Luis Bunuel said, 'God and Country are an unbeatable team; they break all records for oppression and bloodshed. ' Recruiting officers rely heavily on their victims' sense of patriotic duty. In the First World War, women handed out white feathers to young men not in uniform.
Oh, we don't want to lose you, but we think you ought to go, For your King and your country both need you so.
People despised conscientious objectors, even those of the enemy country, because patriotism was held to be an absolute virtue. It is hard to get much more absolute than the 'My country right or wrong' of the professional soldier, for the slogan commits you to kill whomever the politicians of some future date might choose to call enemies. Consequentialist reasoning may influence the polit- ical decision to go to war but, once war is declared, absolutist patriotism takes over with a force and a power not otherwise seen outside religion. A soldier who allows his own thoughts of consequentialist morality to persuade him not to go over the top would likely find himself court-martialled and even executed.
The springboard for this discussion of moral philosophy was a hypothetical religious claim that, without a God, morals are relative and arbitrary. Kant and. other sophisticated moral philosophers apart, and with due recognition given to patriotic fervour, the preferred source of absolute morality is usually a holy book of some kind, interpreted as having an authority far beyond its history's capacity to justify. Indeed, adherents of scriptural authority show distressingly little curiosity about the (normally highly dubious) historical origins of their holy books. The next chapter will demonstrate that, in any case, people who claim to derive their morals from scripture do not really do so in practice. And a very good thing too, as they themselves, on reflection, should agree.

There are two ways in which scripture might be a source of morals or rules for living. One is by direct instruction, for example through the Ten Commandments, which are the subject of such bitter contention in the culture wars of America's boondocks. The other is by example: God, or some other biblical character, might serve as - to use the contemporary jargon - a role model. Both scriptural routes, if followed through religiously (the adverb is used in its metaphoric sense but with an eye to its origin), encourage a system of morals which any civilized modern person, whether religious or not, would find - I can put it no more gently - obnoxious.
To be fair, much of the Bible is not systematically evil but just plain weird, as you would expect of a chaotically cobbled-together anthology of disjointed documents, composed, revised, translated, distorted and 'improved' by hundreds of anonymous authors, editors and copyists, unknown to us and mostly unknown to each

strangeness of the Bible. But unfortunately it is this same weird volume that religious zealots hold up to us as the inerrant source of our morals and rules for living. Those who wish to base their morality literally on the Bible have either not read it or not under- stood it, as Bishop John Shelby Spong, in The Sins of Scripture, rightly observed. Bishop Spong, by the way, is a nice example of a liberal bishop whose beliefs are so advanced as to be almost un- recognizable to the majority of those who call themselves Christians. A British counterpart is Richard Holloway, recently retired as Bishop of Edinburgh. Bishop Holloway even describes himself as a 'recovering Christian'. I had a public discussion with him in Edinburgh, which was one of the most stimulating and

THE OLD TESTAMENT
Begin in Genesis with the well-loved story of Noah, derived from the Babylonian myth of Uta-Napisthim and known from the older mythologies of several cultures. The legend of the animals going into the ark two by two is charming, but the moral of the story of
This may explain some of the sheer
238 T H F G O D D E L U S I O N
Noah is appalling. God took a dim view of humans, so he (with the exception of one family) drowned the lot of them including children and also, for good measure, the rest of the (presumably blameless) animals as well.
Of course, irritated theologians will protest that we don't take the book of Genesis literally any more. But that is my whole point! We pick and choose which bits of scripture to believe, which bits to write off as symbols or allegories. Such picking and choosing is a matter of personal decision, just as much, or as little, as the atheist's decision to follow this moral precept or that was a personal decision, without an absolute foundation. If one of these is 'morality flying by the seat of its pants', so is the other.
In any case, despite the good intentions of the sophisticated theologian, a frighteningly large number of people still do take their scriptures, including the story of Noah, literally. According to Gallup, they include approximately 50 per cent of the US elec- torate. Also, no doubt, many of those Asian holy men who blamed

ranging from drinking and dancing in bars to breaking some footling sabbath rule. Steeped in the story of Noah, and ignorant of all except biblical learning, who can blame them? Their whole edu- cation has led them to view natural disasters as bound up with human affairs, paybacks for human misdemeanours rather than anything so impersonal as plate tectonics. By the way, what pre- sumptuous egocentricity to believe that earth-shaking events, on the scale at which a god (or a tectonic plate) might operate, must always have a human connection. Why should a divine being, with creation and eternity on his mind, care a fig for petty human male- factions? We humans give ourselves such airs, even aggrandizing our poky little 'sins' to the level of cosmic significance!
When I interviewed for television the Reverend Michael Bray, a prominent American anti-abortion activist, I asked him why evangelical Christians were so obsessed with private sexual inclin- ations such as homosexuality, which didn't interfere with anybody else's life. His reply invoked something like self-defence. Innocent citizens are at risk of becoming collateral damage when God chooses to strike a town with a natural disaster because it houses sinners. In 2005, the fine city of New Orleans was catastrophically
T H E ' G O O D ' B O O K A N D T H E M O R A L Z ? 1 T G E I S T 239
flooded in the aftermath of a hurricane, Katrina. The Reverend Pat Robertson, one of America's best-known televangelists and a former presidential candidate, was reported as blaming the hurricane on a lesbian comedian who happened to live in New Orleans. * You'd think an omnipotent God would adopt a slightly more targeted approach to zapping sinners: a judicious heart attack, perhaps, rather than the wholesale destruction of an entire city just because it happened to be the domicile of one lesbian comedian.
In November 2005, the citizens of Dover, Pennsylvania voted off their local school board the entire slate of fundamentalists who had brought the town notoriety, not to say ridicule, by attempting to enforce the teaching of 'intelligent design'. When Pat Robertson heard that the fundamentalists had been democratically defeated at the ballot, he offered a stern warning to Dover:
I'd like to say to the good citizens of Dover, if there is a disaster in your area, don't turn to God. You just rejected him from your city, and don't wonder why he hasn't helped you when problems begin, if they begin, and I'm not saying they will. But if they do, just remember you just voted God out of your city. And if that's the case, then

Pat Robertson would be harmless comedy, were he less typical of those who today hold power and influence in the United States.
In the destruction of Sodom and Gomorrah, the Noah equivalent, chosen to be spared with his family because he was uniquely righteous, was Abraham's nephew Lot. Two male angels were sent to Sodom to warn Lot to leave the city before the brim- stone arrived. Lot hospitably welcomed the angels into his house, whereupon all the men of Sodom gathered around and demanded that Lot should hand the angels over so that they could (what else? )
