attempt to put a number on the probability is quite agreeably funny.

Flynn himself lists the many contradictions between Matthew and Luke, the only two evangelists who treat the
50
birth of Jesus at all. Robert Gillooly shows how all the essential
features of the Jesus legend, including the star in the east, the virgin birth, the veneration of the baby by kings, the miracles, the execution, the resurrection and the ascension are borrowed - every last one of them - from other religions already in existence in the Mediterranean and Near East region. Flynn suggests that Matthew's desire to fulfil messianic prophecies (descent from David, birth in Bethlehem) for the benefit of Jewish readers came into headlong collision with Luke's desire to adapt Christianity for the Gentiles, and hence to press the familiar hot buttons of pagan Hellenistic religions (virgin birth, worship by kings, etc. ). The resulting contradictions are glaring, but consistently overlooked by the faithful.
Sophisticated Christians do not need George Gershwin to convince them that 'The things that you're li'ble / To read in the Bible / It ain't necessarily so'. But there are many unsophisticated Christians out there who think it absolutely is necessarily so - who take the Bible very seriously indeed as a literal and accurate record of history and hence as evidence supporting their religious beliefs. Do these people never open the book that they believe is the literal truth? Why don't they notice those glaring contradictions?
ARCUMENTS FOR GOD'S EXISTENCE 95
Shouldn't a literalist worry about the fact that Matthew traces Joseph's descent from King David via twenty-eight intermediate generations, while Luke has forty-one generations? Worse, there is almost no overlap in the names on the two lists! In any case, if Jesus really was born of a virgin, Joseph's ancestry is irrelevant and can- not be used to fulfil, on Jesus' behalf, the Old Testament prophecy that the Messiah should be descended from David.
The American biblical scholar Bart Ehrman, in a book whose subtitle is The Story Behind Who Changed the New Testament and Why, unfolds the huge uncertainty befogging the New Testament texts. * In the introduction to the book, Professor Ehrman movingly charts his personal educational journey from Bible-believing funda- mentalist to thoughtful sceptic, a journey driven by his dawning realization of the massive fallibility of the scriptures. Significantly, as he moved up the hierarchy of American universities, from rock bottom at the 'Moody Bible Institute', through Wheaton College (a
little bit higher on the scale, but still the alma mater of Billy Graham) to Princeton in the world-beating class at the top, he was at every step warned that he would have trouble maintaining his fundamentalist Christianity in the face of dangerous progressivism. So it proved; and we, his readers, are the beneficiaries. Other refreshingly iconoclastic books of biblical criticism are Robin Lane Fox's The Unauthorized Version, already mentioned, and Jacques Berlinerblau's The Secular Bible: Why Nonbelievers Must Take Religion Seriously.
The four gospels that made it into the official canon were cho- sen, more or less arbitrarily, out of a larger sample of at least a dozen including the Gospels of Thomas, Peter, Nicodemus, Philip,

Bartholomew and Mary Magdalen. It is these additional gospels
that Thomas Jefferson was referring to in his letter to his nephew:

I presume they are the same book, but why do publishers do this kind of thing?

THE GOD DELUSIGN
those whom a council of ecclesiastics have decided for us, to be Pseudo-evangelists, as those they named Evangelists. Because these Pseudo-evangelists pretended to inspiration, as much as the others, and you are to judge their pretensions by your own reason, and not by the reason of those ecclesiastics.
The gospels that didn't make it were omitted by those ecclesiastics perhaps because they included stories that were even more embarrassingly implausible than those in the four canonical ones. The Gospel of Thomas, for example, has numerous anecdotes about the child Jesus abusing his magical powers in the manner of a mischievous fairy, impishly transforming his playmates into goats, or turning mud into sparrows, or giving his father a hand with the carpentry by miraculously lengthening a piece of wood. * It will be said that nobody believes crude miracle stories such as those in the Gospel of Thomas anyway. But there is no more and no less reason to believe the four canonical gospels. All have the status of legends, as factually dubious as the stories of King Arthur and his Knights of the Round Table.
Most of what the four canonical gospels share is derived from a common source, either Mark's gospel or a lost work of which Mark is the earliest extant descendant. Nobody knows who the four evangelists were, but they almost certainly never met Jesus person- ally. Much of what they wrote was in no sense an honest attempt at history but was simply rehashed from the Old Testament, because the gospel-makers were devoutly convinced that the life of
* A. N. Wilson, in his biography of Jesus, casts doubt on the story that Joseph was a carpenter at all. The Greek word tekton does indeed mean carpenter, but it was translated from the Aramaic word naggar, which could mean craftsman or learned man. This is one of several constructive mistranslations that bedevil the Bible, the most famous being the mistranslation of Isaiah's Hebrew for young woman (almah) into the Greek for virgin (parthenos). An easy mistake to make (think of the English words 'maid' and 'maiden' to see how it might have happened), this one translator's slip was to be wildly inflated and give rise to the whole prepos- terous legend of Jesus' mother being a virgin! The only competitor for the title of champion constructive mistranslation of all time also concerns virgins. Ibn Warraq has hilariously argued that in the famous promise of seventy-two virgins to every Muslim martyr, 'virgins' is a mistranslation of 'white raisins of crystal clarity'. Now, if only that had been more widely known, how many innocent victims of sui- cide missions might have been saved? (Ibn Warraq, 'Virgins? What virgins? ', Free Inquiry 26: 1, 2006, 45-6. )
ARGUMENTS FOR GOD'S EXISTENCE 97
Jesus must fulfil Old Testament prophecies. It is even possible to mount a serious, though not widely supported, historical case that Jesus never lived at all, as has been done by, among others, Professor G. A. Wells of the University of London in a number of books, including Did Jesus Exist? .
Although Jesus probably existed, reputable biblical scholars do not in general regard the New Testament (and obviously not the Old Testament) as a reliable record of what actually happened in history, and I shall not consider the Bible further as evidence for any kind of deity. In the farsighted words of Thomas Jefferson, writing to his predecessor, John Adams, 'The day will come when the mystical generation of Jesus, by the Supreme Being as his father, in the womb of a virgin, will be classed with the fable of the gener- ation of Minerva in the brain of Jupiter. '
Dan Brown's novel The Da Vinci Code, and the film made from it, are arousing huge controversy in church circles. Christians are encouraged to boycott the film and picket cinemas that show it. It is indeed fabricated from start to finish: invented, made-up fiction. In that respect, it is exactly like the gospels. The only difference between The Da Vinci Code and the gospels is that the gospels are ancient fiction while The Da Vinci Code is modern fiction.
THE ARGUMENT FROM ADMIRED RELIGIOUS SCIENTISTS
The immense majority of intellectually eminent men disbelieve in Christian religion, but they conceal the fact in public, because they are afraid of losing their incomes.

apologists even add the name of Darwin, about whom persistent, but demonstrably false, rumours of a deathbed conversion con- tinually come around like a bad smell,* ever since they were deliberately started by a certain 'Lady Hope', who spun a touching yarn of Darwin resting against the pillows in the evening light, leaf- ing through the New Testament and confessing that evolution was all wrong. In this section I shall concentrate mostly on scientists, because - for reasons that are perhaps not too hard to imagine - those who trot out the names of admired individuals as religious exemplars very commonly choose scientists.
Newton did indeed claim to be religious. So did almost every- body until - significantly I think - the nineteenth century, when there was less social and judicial pressure than in earlier centuries to profess religion, and more scientific support for abandoning it. There have been exceptions, of course, in both directions. Even before Darwin, not everybody was a believer, as James Haught shows in his 2000 Years of Disbelief: Famous People with the Courage to Doubt. And some distinguished scientists went on believing after Darwin. We have no reason to doubt Michael Faraday's sincerity as a Christian even after the time when he must have known of Darwin's work. He was a member of the Sandemanian sect, which believed (past tense because they are now virtually extinct) in a literal interpretation of the Bible, ritually washed the feet of newly inducted members and drew lots to deter- mine God's will. Faraday became an Elder in 1860, the year after The Origin of Species was published, and he died a Sandemanian in 1867. The experimentalist Faraday's theorist counterpart, James Clerk Maxwell, was an equally devout Christian. So was that other pillar of nineteenth-century British physics, William Thomson, Lord Kelvin, who tried to demonstrate that evolution was ruled out for lack of time. That great thermodynamicist's erroneous datings assumed that the sun was some kind of fire, burning fuel which would have to run out in tens of millions of years, not thousands of millions. Kelvin obviously could not be expected to know about
* Even I have been honoured by prophecies of deathbed conversion. Indeed, they recur with monotonous regularity (see e. g. Steer 2003), each repetition trailing dewy fresh clouds of illusion that it is witty, and the first. I should probably take the precaution of installing a tape-recorder to protect my posthumous reputation. Lalla Ward adds, 'Why mess around with deathbeds? If you're going to sell out, do it in good time to win the Templeton Prize and blame it on senility. '

nuclear energy. Pleasingly, at the British Association meeting of 1903, it fell to Sir George Darwin, Charles's second son, to vindicate his un-knighted father by invoking the Curies' discovery of radium, and confound the earlier estimate of the still living Lord Kelvin.
Great scientists who profess religion become harder to find through the twentieth century, but they are not particularly rare. I suspect that most of the more recent ones are religious only in the Einsteinian sense which, I argued in Chapter 1, is a misuse of the word. Nevertheless, there are some genuine specimens of good scientists who are sincerely religious in the full, traditional sense. Among contemporary British scientists, the same three names crop up with the likeable familiarity of senior partners in a firm of Dickensian lawyers: Peacocke, Stannard and Polkinghorne. All three have either won the Templeton Prize or are on the Templeton Board of Trustees. After amicable discussions with all of them, both in pub- lic and in private, I remain baffled, not so much by their belief in a cosmic lawgiver of some kind, as by their belief in the details of the Christian religion: resurrection, forgiveness of sins and all.
There are some corresponding examples in the United States, for example Francis Collins, administrative head of the American branch of the official Human Genome Project. * But, as in Britain, they stand out for their rarity and are a subject of amused baffle- ment to their peers in the academic community. In 1996, in the gardens of his old college at Cambridge, Clare, I interviewed my friend Jim Watson, founding genius of the Human Genome Project, for a BBC television documentary that I was making on Gregor Mendel, founding genius of genetics itself. Mendel, of course, was a religious man, an Augustinian monk; but that was in the nine- teenth century, when becoming a monk was the easiest way for the young Mendel to pursue his science. For him, it was the equivalent of a research grant. I asked Watson whether he knew many religious scientists today. He replied: 'Virtually none. Occasionally I meet them, and I'm a bit embarrassed [laughs] because, you know, I can't believe anyone accepts truth by revelation. '
Francis Crick, Watson's co-founder of the whole molecular genetics revolution, resigned his fellowship at Churchill College,
* Not to be confused with the unofficial human genome project, led by that bril- liant (and non-religious) 'buccaneer' of science, Craig Venter.

Cambridge, because of the college's decision to build a chapel (at the behest of a benefactor). In my interview with Watson at Clare, I conscientiously put it to him that, unlike him and Crick, some people see no conflict between science and religion, because they claim science is about how things work and religion is about what it is all for. Watson retorted: 'Well I don't think we're for anything. We're just products of evolution. You can say, "Gee, your life must be pretty bleak if you don't think there's a purpose. " But I'm antic- ipating having a good lunch. ' We did have a good lunch, too.
The efforts of apologists to find genuinely distinguished modern scientists who are religious have an air of desperation, generating the unmistakably hollow sound of bottoms of barrels being scraped. The only website I could find that claimed to list 'Nobel Prize-winning Scientific Christians' came up with six, out of a total of several hundred scientific Nobelists. Of these six, it turned out that four were not Nobel Prize-winners at all; and at least one, to my certain knowledge, is a non-believer who attends church for purely social reasons. A more systematic study by Benjamin Beit- Hallahmi 'found that among Nobel Prize laureates in the sciences, as well as those in literature, there was a remarkable degree of
52 irreligiosity, as compared to the populations they came from'.
A study in the leading journal Nature by Larson and Witham in 1998 showed that of those American scientists considered eminent enough by their peers to have been elected to the National Academy of Sciences (equivalent to being a Fellow of the Royal Society in
53 Britain) only about 7 per cent believe in a personal God. This
overwhelming preponderance of atheists is almost the exact opposite of the profile of the American population at large, of whom more than 90 per cent are believers in some sort of super- natural being. The figure for less eminent scientists, not elected to the National Academy, is intermediate. As with the more distinguished sample, religious believers are in a minority, but a less dramatic minority of about 40 per cent. It is completely as I would expect that American scientists are less religious than the American public generally, and that the most distinguished scientists are the least religious of all. What is remarkable is the polar opposition between the religiosity of the American public at large and the
54 atheism of the intellectual elite.
ARGUMENTS FOR GOD'S EXISTENCE 101
It is faintly amusing that the leading creationist website,
'Answers in Genesis', cites the Larson and Witham study, not in
evidence that there might be something wrong with religion, but as
a weapon in their internal battle against those rival religious
apologists who claim that evolution is compatible with religion.
Under the headline 'National Academy of Science is Godless to the
55
'Answers in Genesis' is pleased to quote the concluding
Core',
paragraph of Larson and Witham's letter to the editor of Nature:
As we compiled our findings, the NAS [National Academy of Sciences] issued a booklet encouraging the teaching of evolution in public schools, an ongoing source of friction between the scientific community and some conservative Christians in the United States. The booklet assures readers, 'Whether God exists or not is a question about which science is neutral. ' NAS president Bruce Alberts said: 'There are many very outstanding members of this academy who are very religious people, people who believe in evolution, many of them biologists. ' Our survey suggests otherwise.
Alberts, one feels, embraced 'NOMA' for the reasons I discussed in 'The Neville Chamberlain school of evolutionists' (see Chapter 2). 'Answers in Genesis' has a very different agenda.
The equivalent of the US National Academy of Sciences in Britain (and the Commonwealth, including Canada, Australia, New Zealand, India, Pakistan, anglophone Africa, etc. ) is the Royal Society. As this book goes to press, my colleagues R. Elisabeth Cornwell and Michael Stirrat are writing up their comparable, but more thorough, research on the religious opinions of the Fellows of the Royal Society (FRS). The authors' conclusions will be published in full later, but they have kindly allowed me to quote preliminary results here. They used a standard technique for scaling opinion, the Likert-type seven-point scale. All 1,074 Fellows of the Royal Society who possess an email address (the great majority) were polled, and about 23 per cent responded (a good figure for this kind of study). They were offered various propositions, for example: 'I believe in a personal God, that is one who takes an interest in
102 THH G()D DEI. USIGN
individuals, hears and answers prayers, is concerned with sin and transgressions, and passes judgement. ' For each such proposition, they were invited to choose a number from 1 (strong disagreement) to 7 (strong agreement). It is a little hard to compare the results directly with the Larson and Witham study, because Larson and Witham offered their academicians only a three-point scale, not a seven-point scale, but the overall trend is the same. The over- whelming majority of FRS, like the overwhelming majority of US Academicians, are atheists. Only 3. 3 per cent of the Fellows agreed strongly with the statement that a personal god exists (i. e. chose 7 on the scale), while 78. 8 per cent strongly disagreed (i. e. chose 1 on the scale). If you define 'believers' as those who chose 6 or 7, and if you define 'unbelievers' as those who chose 1 or 2, there were a massive 213 unbelievers and a mere 12 believers. Like Larson and Witham, and as also noted by Beit-Hallahmi and Argyle, Cornwell and Stirrat found a small but significant tendency for biological scientists to be even more atheistic than physical scientists. For the details, and all the rest of their very interesting conclusions, please
56 refer to their own paper when it is published.
Moving on from the elite scientists of the National Academy and the Royal Society, is there any evidence that, in the population at large, atheists are likely to be drawn from among the better educated and more intelligent? Several research studies have been published on the statistical relationship between religiosity and educational level, or religiosity and IQ. Michael Shermer, in How We Believe: The Search for God in an Age of Science, describes a large survey of randomly chosen Americans that he and his colleague Frank Sulloway carried out. Among their many interest- ing results was the discovery that religiosity is indeed negatively correlated with education (more highly educated people are less likely to be religious). Religiosity is also negatively correlated with interest in science and (strongly) with political liberalism. None of this is surprising, nor is the fact that there is a positive correlation between religiosity and parents' religiosity. Sociologists studying British children have found that only about one in twelve break away from their parents' religious beliefs.
As you might expect, different researchers measure things in different ways, so it is hard to compare different studies. Meta-
A R G U M E N T S F O R G OD' S E X I S T E N C E 103
analysis is the technique whereby an investigator looks at all the research papers that have been published on a topic, and counts up the number of papers that have concluded one thing, versus the number that have concluded something else. On the subject of religion and IQ, the only meta-analysis known to me was published by Paul Bell in Mensa Magazine in 2002 (Mensa is the society of individuals with a high IQ, and their journal not surprisingly
57 includes articles on the one thing that draws them together). Bell
concluded: 'Of 43 studies carried out since 1927 on the relationship between religious belief and one's intelligence and/or educational level, all but four found an inverse connection. That is, the higher one's intelligence or education level, the less one is likely to be religious or hold "beliefs" of any kind. '
A meta-analysis is almost bound to be less specific than any one of the studies that contributed to it. It would be nice to have more studies along these lines, as well as more studies of the members of elite bodies such as other national academies, and winners of major prizes and medals such as the Nobel, the Crafoord, the Field, the Kyoto, the Cosmos and others. I hope that future editions of this book will include such data. A reasonable conclusion from existing studies is that religious apologists might be wise to keep quieter than they habitually do on the subject of admired role models, at least where scientists are concerned.
PASCAL'S WAGER
The great French mathematician Blaise Pascal reckoned that, how- ever long the odds against God's existence might be, there is an even larger asymmetry in the penalty for guessing wrong. You'd better believe in God, because if you are right you stand to gain eternal bliss and if you are wrong it won't make any difference anyway. On the other hand, if you don't believe in God and you turn out to be wrong you get eternal damnation, whereas if you are right it makes no difference. On the face of it the decision is a no-brainer. Believe in God.
There is something distinctly odd about the argument, however.
104 THE GOD DEIUS1ON
Believing is not something you can decide to do as a matter of policy. At least, it is not something I can decide to do as an act of will. I can decide to go to church and I can decide to recite the Nicene Creed, and I can decide to swear on a stack of bibles that I believe every word inside them. But none of that can make me actually believe it if I don't. Pascal's wager could only ever be an argument for feigning belief in God. And the God that you claim to believe in had better not be of the omniscient kind or he'd see through the deception. The ludicrous idea that believing is something you can decide to do is deliciously mocked by Douglas Adams in Dirk Gently's Holistic Detective Agency, where we meet the robotic Electric Monk, a labour-saving device that you buy 'to do your believing for you'. The de luxe model is advertised as 'Capable of believing things they wouldn't believe in Salt Lake City'.
But why, in any case, do we so readily accept the idea that the one thing you must do if you want to please God is believe in him? What's so special about believing? Isn't it just as likely that God would reward kindness, or generosity, or humility? Or sincerity? What if God is a scientist who regards honest seeking after truth as the supreme virtue? Indeed, wouldn't the designer of the universe have to be a scientist? Bertrand Russell was asked what he would say if he died and found himself confronted by God, demanding to know why Russell had not believed in him. 'Not enough evidence, God, not enough evidence,' was Russell's (I almost said immortal) reply. Mightn't God respect Russell for his courageous scepticism (let alone for the courageous pacifism that landed him in prison in the First World War) far more than he would respect Pascal for his cowardly bet-hedging? And, while we cannot know which way God would jump, we don't need to know in order to refute Pascal's Wager. We are talking about a bet, remember, and Pascal wasn't claiming that his wager enjoyed anything but very long odds. Would you bet on God's valuing dishonestly faked belief (or even honest belief) over honest scepticism?
Then again, suppose the god who confronts you when you die turns out to be Baal, and suppose Baal is just as jealous as his old rival Yahweh was said to be. Mightn't Pascal have been better off wagering on no god at all rather than on the wrong god? Indeed,
A R G U M E N T S F O R G O D ' S E X 1 S T E N C E 105
doesn't the sheer number of potential gods and goddesses on whom one might bet vitiate Pascal's whole logic? Pascal was probably joking when he promoted his wager, just as I am joking in my dis- missal of it. But I have encountered people, for example in the question session after a lecture, who have seriously advanced Pascal's Wager as an argument in favour of believing in God, so it was right to give it a brief airing here.
Is it possible, finally, to argue for a sort of anti-Pascal wager? Suppose we grant that there is indeed some small chance that God exists. Nevertheless, it could be said that you will lead a better, fuller life if you bet on his not existing, than if you bet on his exist- ing and therefore squander your precious time on worshipping him, sacrificing to him, fighting and dying for him, etc. I won't pursue the question here, but readers might like to bear it in mind when we come to later chapters on the evil consequences that can flow from religious belief and observance.
BAYESIAN ARGUMENTS
I think the oddest case I have seen attempted for the existence of God is the Bayesian argument recently put forward by Stephen Unwin in The Probability of God. I hesitated before including this argument, which is both weaker and less hallowed by antiquity than others. Unwin's book, however, received considerable journal- istic attention when it was published in 2003, and it does give the opportunity to bring some explanatory threads together. I have some sympathy with his aims because, as argued in Chapter 2, I believe the existence of God as a scientific hypothesis is, at least in principle, investigable.
Also, Unwin's quixotic attempt to put a number on the probability is quite agreeably funny.
The book's subtitle, A Simple Calculation that Proves the Ultimate Truth, has all the hallmarks of a late addition by the publisher, because such overweening confidence is not to be found in Unwin's text. The book is better seen as a 'How To' manual, a sort of Bayes' Theorem for Dummies, using the existence of God as a semi-facetious case study. Unwin could equally well have used a
106 T H E G O D D E I, U S I O N
hypothetical murder as his test case to demonstrate Bayes' Theorem. The detective marshals the evidence. The fingerprints on the revolver point to Mrs Peacock. Quantify that suspicion by slapping a numerical likelihood on her. However, Professor Plum had a motive to frame her. Reduce the suspicion of Mrs Peacock by a corresponding numerical value. The forensic evidence suggests a 70 per cent likelihood that the revolver was fired accurately from a long distance, which argues for a culprit with military training. Quantify our raised suspicion of Colonel Mustard. The Reverend Green has the most plausible motive for murder. * Increase our numerical assessment of his likelihood. But the long blond hair on the victim's jacket could only belong to Miss Scarlet. . . and so on. A mix of more or less subjectively judged likelihoods churns around in the detective's mind, pulling him in different directions. Bayes' Theorem is supposed to help him to a conclusion. It is a mathe- matical engine for combining many estimated likelihoods and coming up with a final verdict, which bears its own quantitative estimate of likelihood. But of course that final estimate can only be as good as the original numbers fed in. These are usually subjectively judged, with all the doubts that inevitably flow from that. The GIGO principle (Garbage In, Garbage Out) is applicable here - and, in the case of Unwin's God example, applicable is too mild a word.
Unwin is a risk management consultant who carries a torch for Bayesian inference, as against rival statistical methods. He illustrates Bayes' Theorem by taking on, not a murder, but the biggest test case of all, the existence of God. The plan is to start with complete uncertainty, which he chooses to quantify by assign- ing the existence and non-existence of God a 50 per cent starting likelihood each. Then he lists six facts that might bear on the matter, puts a numerical weighting on each, feeds the six numbers into the engine of Bayes' Theorem and sees what number pops out. The trouble is that (to repeat) the six weightings are not measured quantities but simply Stephen Unwin's own personal judgements, turned into numbers for the sake of the exercise. The six facts are:
* The Reverend Green is the character's name in the versions of Cluedo sold in Britain (where the game originated), Australia, New Zealand, India and all other English-speaking areas except North America, where he suddenly becomes Mr Green. What is that all about?

2 People do evil things (Hitler, Stalin, Saddam Hussein).
3 Nature does evil things (earthquakes, tsunamis, hurricanes).
4 There might be minor miracles (I lost my keys and found them again).
5 There might be major miracles (Jesus might have risen from the dead).
6 People have religious experiences.
For what it is worth (nothing, in my opinion), at the end of a ding-dong Bayesian race in which God surges ahead in the betting, then drops way back, then claws his way up to the 50 per cent mark from which he started, he finally ends up enjoying, in Unwin's estimation, a 67 per cent likelihood of existing. Unwin then decides that his Bayesian verdict of 67 per cent isn't high enough, so he takes the bizarre step of boosting it to 95 per cent by an emergency injection of 'faith'. It sounds like a joke, but that really is how he proceeds. I wish I could say how he justifies it, but there really is nothing to say. I have met this kind of absurdity elsewhere, when I have challenged religious but otherwise intelligent scientists to justify their belief, given their admission that there is no evidence: 'I admit that there's no evidence. There's a reason why it's called faith' (this last sentence uttered with almost truculent conviction, and no hint of apology or defensiveness).
Surprisingly, Unwin's list of six statements does not include the argument from design, nor any of Aquinas' five 'proofs', nor any of the various ontological arguments. He has no truck with them: they don't contribute even a minor fillip to his numerical estimate of God's likelihood. He discusses them and, as a good statistician, dis- misses them as empty. I think this is to his credit, although his reason for discounting the design argument is different from mine. But the arguments that he does admit through his Bayesian door are, it seems to me, just as weak. That is only to say that the sub- jective likelihood weightings I would give to them are different from his, and who cares about subjective judgements anyway? He thinks the fact that we have a sense of right and wrong counts
108 T H E G O D D E L U S I O N
strongly in God's favour, whereas I don't see that it should really shift him, in either direction, from his initial prior expectation. Chapters 6 and 7 will show that there is no good case to be made for our possession of a sense of right and wrong having any clear connection with the existence of a supernatural deity. As in the case of our ability to appreciate a Beethoven quartet, our sense of good- ness (though not necessarily our inducement to follow it) would be the way it is with a God and without a God.
On the other hand, Unwin thinks the existence of evil, especially natural catastrophes such as earthquakes and tsunamis, counts strongly against the likelihood that God exists. Here, Unwin's judgement is opposite to mine but goes along with many un- comfortable theologians. 'Theodicy' (the vindication of divine providence in the face of the existence of evil) keeps theologians awake at night. The authoritative Oxford Companion to Philosophy gives the problem of evil as 'the most powerful objection to traditional theism'. But it is an argument only against the existence of a good God. Goodness is no part of the definition of the God Hypothesis, merely a desirable add-on.
Admittedly, people of a theological bent are often chronically incapable of distinguishing what is true from what they'd like to be true. But, for a more sophisticated believer in some kind of super- natural intelligence, it is childishly easy to overcome the problem of evil. Simply postulate a nasty god - such as the one who stalks every page of the Old Testament. Or, if you don't like that, invent a separate evil god, call him Satan, and blame his cosmic battle against the good god for the evil in the world. Or - a more sophisticated solution - postulate a god with grander things to do than fuss about human distress. Or a god who is not indifferent to suffering but regards it as the price that has to be paid for free will in an orderly, lawful cosmos. Theologians can be found buying into all these rationalizations.
For these reasons, if I were redoing Unwin's Bayesian exercise, neither the problem of evil nor moral considerations in general would shift me far, one way or the other, from the null hypothesis (Unwin's 50 per cent). But I don't want to argue the point because, in any case, I can't get excited about personal opinions, whether Unwin's or mine.
A R G U M E N T S F O R G O D ' S E X I S T E N C E 109
There is a much more powerful argument, which does not depend upon subjective judgement, and it is the argument from improbability. It really does transport us dramatically away from 50 per cent agnosticism, far towards the extreme of theism in the view of many theists, far towards the extreme of atheism in my view. I have alluded to it several times already. The whole argument turns on the familiar question 'Who made God? ', which most
thinking people discover for themselves. A designer God cannot be used to explain organized complexity because any God capable of designing anything would have to be complex enough to demand the same kind of explanation in his own right. God presents an infinite regress from which he cannot help us to escape. This argu- ment, as I shall show in the next chapter, demonstrates that God, though not technically disprovable, is very very improbable indeed.
CHAPTER 4 Why there almost certainly is no God
The priests of the different religious sects . . . dread the advance of science as witches do the approach of daylight, and scowl on the fatal harbinger announcing the subdivision of the duperies on which they live.
THOMAS JEFFERSON
WHY TIIERE ALMOST CERTAINLY IS NO GOD 113
THE ULTIMATE BOEING 747
The argument from improbability is the big one. In the traditional guise of the argument from design, it is easily today's most popular argument offered in favour of the existence of God and it is seen, by an amazingly large number of theists, as completely and utterly convincing. It is indeed a very strong and, I suspect, unanswerable argument - but in precisely the opposite direction from the theist's intention. The argument from improbability, properly deployed, comes close to proving that God does not exist. My name for the statistical demonstration that God almost certainly does not exist is the Ultimate Boeing 747 gambit.
The name comes from Fred Hoyle's amusing image of the Boeing 747 and the scrapyard. I am not sure whether Hoyle ever wrote it down himself, but it was attributed to him by his close colleague
58 Chandra Wickramasinghe and is presumably authentic. Hoyle
said that the probability of life originating on Earth is no greater than the chance that a hurricane, sweeping through a scrapyard, would have the luck to assemble a Boeing 747. Others have borrowed the metaphor to refer to the later evolution of complex living bodies, where it has a spurious plausibility. The odds against assembling a fully functioning horse, beetle or ostrich by randomly shuffling its parts are up there in 747 territory. This, in a nutshell, is the creationist's favourite argument - an argument that could be made only by somebody who doesn't understand the first thing about natural selection: somebody who thinks natural selection is a theory of chance whereas - in the relevant sense of chance - it is the opposite.
The creationist misappropriation of the argument from im- probability always takes the same general form, and it doesn't make any difference if the creationist chooses to masquerade in the politically expedient fancy dress of 'intelligent design' (ID). * Some observed phenomenon - often a living creature or one of its more complex organs, but it could be anything from a molecule up to the universe itself - is correctly extolled as statistically improbable. Sometimes the language of information theory is used: the Darwinian is challenged to explain the source of all the information
Intelligent design has been unkindly described as creationism in a cheap tuxedo.
114 THE GOD DELUSION
in living matter, in the technical sense of information content as a measure of improbability or 'surprise value'. Or the argument may invoke the economist's hackneyed motto: there's no such thing as a free lunch - and Darwinism is accused of trying to get something for nothing. In fact, as I shall show in this chapter, Darwinian natural selection is the only known solution to the otherwise un- answerable riddle of where the information comes from. It turns out to be the God Hypothesis that tries to get something for nothing. God tries to have his free lunch and be it too. However statistically improbable the entity you seek to explain by invoking a designer, the designer himself has got to be at least as improbable. God is the Ultimate Boeing 747.
The argument from improbability states that complex things could not have come about by chance. But many people define 'come about by chance' as a synonym for 'come about in the absence of deliberate design'. Not surprisingly, therefore, they think improbability is evidence of design. Darwinian natural selection shows how wrong this is with respect to biological improbability. And although Darwinism may not be directly relevant to the inanimate world - cosmology, for example - it raises our consciousness in areas outside its original territory of biology.
A deep understanding of Darwinism teaches us to be wary of the easy assumption that design is the only alternative to chance, and teaches us to seek out graded ramps of slowly increasing complexity. Before Darwin, philosophers such as Hume understood that the improbability of life did not mean it had to be designed, but they couldn't imagine the alternative. After Darwin, we all should feel, deep in our bones, suspicious of the very idea of design. The illusion of design is a trap that has caught us before, and Darwin should have immunized us by raising our consciousness. Would that he had succeeded with all of us.
NATURAL SELECTION AS A CONSCIOUSNESS-RAISER
In a science-fiction starship, the astronauts were homesick: 'Just to
W H Y T H E R E A I . M O S T C E R T A I N L Y I S NO G O D 1 1 5
think that it's springtime back on Earth! ' You may not immediately see what's wrong with this, so deeply ingrained is the unconscious northern hemisphere chauvinism in those of us who live there, and even some who don't. 'Unconscious' is exactly right. That is where consciousness-raising comes in. It is for a deeper reason than gimmicky fun that, in Australia and New Zealand, you can buy maps of the world with the South Pole on top. What splendid consciousness-raisers those maps would be, pinned to the walls of our northern hemisphere classrooms. Day after day, the children would be reminded that 'north' is an arbitrary polarity which has no monopoly on 'up'. The map would intrigue them as well as raise their consciousness. They'd go home and tell their parents - and, by the way, giving children something with which to surprise their
parents is one of the greatest gifts a teacher can bestow.
It was the feminists who raised my consciousness of the power of consciousness-raising. 'Herstory' is obviously ridiculous, if only because the 'his' in 'history' has no etymological connection with the masculine pronoun. It is as etymologically silly as the sacking, in 1999, of a Washington official whose use of 'niggardly' was held to give racial offence. But even daft examples like 'niggardly' or 'herstory' succeed in raising consciousness. Once we have smoothed our philological hackles and stopped laughing, herstory shows us history from a different point of view. Gendered pronouns notoriously are the front line of such consciousness-raising. He or she must ask himself or herself whether his or her sense of style could ever allow himself or herself to write like this. But if we can just get over the clunking infelicity of the language, it raises our consciousness to the sensitivities of half the human race. Man, mankind, the Rights of Man, all men are created equal, one man one vote - English too often seems to exclude woman. * When I was young, it never occurred to me that women might feel slighted by a phrase like 'the future of man'. During the intervening decades, we have all had our consciousness raised. Even those who still use 'man' instead of 'human' do so with an air of self-conscious apology - or truculence, taking a stand for traditional language, even deliberately to rile feminists. All participants in the Zeitgeist
* Classical Latin and Greek were better equipped. Latin homo (Greek anthropo-) means human, as opposed to vir (andro-) which means man, and fetnina (gyne-) which means woman. Thus anthropology pertains to all humanity, where androl- ogy and gynecology are sexually exclusive branches of medicine.
116 THE COD DELUSION
have had their consciousness raised, even those who choose to respond negatively by digging in their heels and redoubling the offence.
Feminism shows us the power of consciousness-raising, and I want to borrow the technique for natural selection. Natural selection not only explains the whole of life; it also raises our consciousness to the power of science to explain how organized complexity can emerge from simple beginnings without any deliberate guidance. A full understanding of natural selection encourages us to move boldly into other fields. It arouses our suspicion, in those other fields, of the kind of false alternatives that once, in pre-Darwinian days, beguiled biology. Who, before Darwin, could have guessed that something so apparently designed as a dragonfly's wing or an eagle's eye was really the end product of a long sequence of non-random but purely natural causes?
Douglas Adams's moving and funny account of his own con- version to radical atheism - he insisted on the 'radical' in case anybody should mistake him for an agnostic - is testimony to the power of Darwinism as a consciousness-raiser. I hope I shall be for- given the self-indulgence that will become apparent in the following quotation. My excuse is that Douglas's conversion by my earlier books - which did not set out to convert anyone - inspired me to dedicate to his memory this book - which does! In an interview, reprinted posthumously in The Salmon of Doubt, he was asked by a journalist how he became an atheist. He began his reply by explaining how he became an agnostic, and then proceeded:
And I thought and thought and thought. But I just didn't have enough to go on, so I didn't really come to any resolution. I was extremely doubtful about the idea of god, but I just didn't know enough about anything to have a good working model of any other explanation for, well, life, the universe, and everything to put in its place. But I kept at it, and I kept reading and I kept thinking. Sometime around my early thirties I stumbled upon evolutionary biology, particularly in the form of Richard Dawkins's books The Selfish Gene and then The Blind Watchmaker, and suddenly (on, I think the second
W H Y T H E R E A L . M O S T C E R T A I N L . Y I S NO G O D
1 1 7
reading of The Selfish Gene) it all fell into place. It was a concept of such stunning simplicity, but it gave rise, naturally, to all of the infinite and baffling complexity of life. The awe it inspired in me made the awe that people talk about in respect of religious experience seem, frankly, silly beside it. I'd take the awe of understanding over the
59 awe of ignorance any day.
The concept of stunning simplicity that he was talking about was, of course, nothing to do with me. It was Darwin's theory of evolution by natural selection - the ultimate scientific consciousness- raiser. Douglas, I miss you. You are my cleverest, funniest, most open-minded, wittiest, tallest, and possibly only convert. I hope this book might have made you laugh - though not as much as you made me.
That scientifically savvy philosopher Daniel Dennett pointed out that evolution counters one of the oldest ideas we have: 'the idea that it takes a big fancy smart thing to make a lesser thing. I call that the trickle-down theory of creation. You'll never see a spear making a spear maker. You'll never see a horse shoe making
60
a blacksmith. You'll never see a pot making a potter. '
discovery of a workable process that does that very counter- intuitive thing is what makes his contribution to human thought so revolutionary, and so loaded with the power to raise consciousness.
It is surprising how necessary such consciousness-raising is, even in the minds of excellent scientists in fields other than biology. Fred Hoyle was a brilliant physicist and cosmologist, but his Boeing 747 misunderstanding, and other mistakes in biology such as his attempt to dismiss the fossil Archaeopteryx as a hoax, suggest that he needed to have his consciousness raised by some good exposure to the world of natural selection. At an intellectual level, I suppose he understood natural selection. But perhaps you need to be steeped in natural selection, immersed in it, swim about in it, before you can truly appreciate its power.
Other sciences raise our consciousness in different ways. Fred Hoyle's own science of astronomy puts us in our place, meta- phorically as well as literally, scaling down our vanity to fit the tiny stage on which we play out our lives - our speck of debris from the
Darwin's
118 THE GOD DELUSION
cosmic explosion. Geology reminds us of our brief existence both as individuals and as a species. It raised John Ruskin's conscious- ness and provoked his memorable heart cry of 1851: 'If only the Geologists would let me alone, I could do very well, but those dreadful hammers! I hear the clink of them at the end of every cadence of the Bible verses. ' Evolution does the same thing for our sense of time - not surprisingly, since it works on the geological timescale. But Darwinian evolution, specifically natural selection, does something more. It shatters the illusion of design within the domain of biology, and teaches us to be suspicious of any kind of design hypothesis in physics and cosmology as well. I think the physicist Leonard Susskind had this in mind when he wrote, 'I'm not an historian but I'll venture an opinion: Modern cosmology really began with Darwin and Wallace. Unlike anyone before them, they provided explanations of our existence that completely rejected supernatural agents . . . Darwin and Wallace set a standard
61
not only for the life sciences but for cosmology as well. ' Other
physical scientists who are far above needing any such consciousness-raising are Victor Stenger, whose book Has Science Found God? (the answer is no) I strongly recommend, and Peter Atkins, whose Creation Revisited is my favourite work of scientific prose poetry.
I am continually astonished by those theists who, far from having their consciousness raised in the way that I propose, seem to rejoice in natural selection as 'God's way of achieving his creation'. They note that evolution by natural selection would be a very easy and neat way to achieve a world full of life. God wouldn't need to do anything at all! Peter Atkins, in the book just mentioned, takes this line of thought to a sensibly godless conclusion when he postulates a hypothetically lazy God who tries to get away with as little as possible in order to make a universe containing life. Atkins's lazy God is even lazier than the deist God of the eighteenth-century Enlightenment: deus otiosus - literally God at leisure, unoccupied, unemployed, superfluous, useless. Step by step, Atkins succeeds in reducing the amount of work the lazy God has to do until he finally ends up doing nothing at all: he might as well not bother to exist. My memory vividly hears Woody Allen's perceptive whine: 'If it turns out that there is a God, I don't think that he's evil. But the

worst that you can say about him is that basically he's an under- achiever. '
IRREDUCIBLE COMPLEXITY
It is impossible to exaggerate the magnitude of the problem that Darwin and Wallace solved. I could mention the anatomy, cellular structure, biochemistry and behaviour of literally any living organism by example. But the most striking feats of apparent design are those picked out - for obvious reasons - by creationist authors, and it is with gentle irony that I derive mine from a creationist book. Life - How Did It Get Here? , with no named author but published by the Watchtower Bible and Tract Society in sixteen languages and eleven million copies, is obviously a firm favourite because no fewer than six of those eleven million copies have been sent to me as unsolicited gifts by well-wishers from around the world.
Picking a page at random from this anonymous and lavishly dis- tributed work, we find the sponge known as Venus' Flower Basket (Euplectella), accompanied by a quotation from Sir David Attenborough, no less: 'When you look at a complex sponge skeleton such as that made of silica spicules which is known as Venus' Flower Basket, the imagination is baffled. How could quasi- independent microscopic cells collaborate to secrete a million glassy splinters and construct such an intricate and beautiful lattice? We do not know.

birth of Jesus at all. Robert Gillooly shows how all the essential
features of the Jesus legend, including the star in the east, the virgin birth, the veneration of the baby by kings, the miracles, the execution, the resurrection and the ascension are borrowed - every last one of them - from other religions already in existence in the Mediterranean and Near East region. Flynn suggests that Matthew's desire to fulfil messianic prophecies (descent from David, birth in Bethlehem) for the benefit of Jewish readers came into headlong collision with Luke's desire to adapt Christianity for the Gentiles, and hence to press the familiar hot buttons of pagan Hellenistic religions (virgin birth, worship by kings, etc. ). The resulting contradictions are glaring, but consistently overlooked by the faithful.
Sophisticated Christians do not need George Gershwin to convince them that 'The things that you're li'ble / To read in the Bible / It ain't necessarily so'. But there are many unsophisticated Christians out there who think it absolutely is necessarily so - who take the Bible very seriously indeed as a literal and accurate record of history and hence as evidence supporting their religious beliefs. Do these people never open the book that they believe is the literal truth? Why don't they notice those glaring contradictions?
ARCUMENTS FOR GOD'S EXISTENCE 95
Shouldn't a literalist worry about the fact that Matthew traces Joseph's descent from King David via twenty-eight intermediate generations, while Luke has forty-one generations? Worse, there is almost no overlap in the names on the two lists! In any case, if Jesus really was born of a virgin, Joseph's ancestry is irrelevant and can- not be used to fulfil, on Jesus' behalf, the Old Testament prophecy that the Messiah should be descended from David.
The American biblical scholar Bart Ehrman, in a book whose subtitle is The Story Behind Who Changed the New Testament and Why, unfolds the huge uncertainty befogging the New Testament texts. * In the introduction to the book, Professor Ehrman movingly charts his personal educational journey from Bible-believing funda- mentalist to thoughtful sceptic, a journey driven by his dawning realization of the massive fallibility of the scriptures. Significantly, as he moved up the hierarchy of American universities, from rock bottom at the 'Moody Bible Institute', through Wheaton College (a
little bit higher on the scale, but still the alma mater of Billy Graham) to Princeton in the world-beating class at the top, he was at every step warned that he would have trouble maintaining his fundamentalist Christianity in the face of dangerous progressivism. So it proved; and we, his readers, are the beneficiaries. Other refreshingly iconoclastic books of biblical criticism are Robin Lane Fox's The Unauthorized Version, already mentioned, and Jacques Berlinerblau's The Secular Bible: Why Nonbelievers Must Take Religion Seriously.
The four gospels that made it into the official canon were cho- sen, more or less arbitrarily, out of a larger sample of at least a dozen including the Gospels of Thomas, Peter, Nicodemus, Philip,

Bartholomew and Mary Magdalen. It is these additional gospels
that Thomas Jefferson was referring to in his letter to his nephew:
I forgot to observe, when speaking of the New Testament, that you should read all the histories of Christ, as well of
* I give the subtitle because that is all I am confident of. The main title of my copy of the book, published by Continuum of London, is Whose Word Is It? I can find nothing in this edition to say whether it is the same book as the American publication by Harper San Francisco, which I haven't seen, whose main title is Misquoting Jesus. I presume they are the same book, but why do publishers do this kind of thing?

THE GOD DELUSIGN
those whom a council of ecclesiastics have decided for us, to be Pseudo-evangelists, as those they named Evangelists. Because these Pseudo-evangelists pretended to inspiration, as much as the others, and you are to judge their pretensions by your own reason, and not by the reason of those ecclesiastics.
The gospels that didn't make it were omitted by those ecclesiastics perhaps because they included stories that were even more embarrassingly implausible than those in the four canonical ones. The Gospel of Thomas, for example, has numerous anecdotes about the child Jesus abusing his magical powers in the manner of a mischievous fairy, impishly transforming his playmates into goats, or turning mud into sparrows, or giving his father a hand with the carpentry by miraculously lengthening a piece of wood. * It will be said that nobody believes crude miracle stories such as those in the Gospel of Thomas anyway. But there is no more and no less reason to believe the four canonical gospels. All have the status of legends, as factually dubious as the stories of King Arthur and his Knights of the Round Table.
Most of what the four canonical gospels share is derived from a common source, either Mark's gospel or a lost work of which Mark is the earliest extant descendant. Nobody knows who the four evangelists were, but they almost certainly never met Jesus person- ally. Much of what they wrote was in no sense an honest attempt at history but was simply rehashed from the Old Testament, because the gospel-makers were devoutly convinced that the life of
* A. N. Wilson, in his biography of Jesus, casts doubt on the story that Joseph was a carpenter at all. The Greek word tekton does indeed mean carpenter, but it was translated from the Aramaic word naggar, which could mean craftsman or learned man. This is one of several constructive mistranslations that bedevil the Bible, the most famous being the mistranslation of Isaiah's Hebrew for young woman (almah) into the Greek for virgin (parthenos). An easy mistake to make (think of the English words 'maid' and 'maiden' to see how it might have happened), this one translator's slip was to be wildly inflated and give rise to the whole prepos- terous legend of Jesus' mother being a virgin! The only competitor for the title of champion constructive mistranslation of all time also concerns virgins. Ibn Warraq has hilariously argued that in the famous promise of seventy-two virgins to every Muslim martyr, 'virgins' is a mistranslation of 'white raisins of crystal clarity'. Now, if only that had been more widely known, how many innocent victims of sui- cide missions might have been saved? (Ibn Warraq, 'Virgins? What virgins? ', Free Inquiry 26: 1, 2006, 45-6. )
ARGUMENTS FOR GOD'S EXISTENCE 97
Jesus must fulfil Old Testament prophecies. It is even possible to mount a serious, though not widely supported, historical case that Jesus never lived at all, as has been done by, among others, Professor G. A. Wells of the University of London in a number of books, including Did Jesus Exist? .
Although Jesus probably existed, reputable biblical scholars do not in general regard the New Testament (and obviously not the Old Testament) as a reliable record of what actually happened in history, and I shall not consider the Bible further as evidence for any kind of deity. In the farsighted words of Thomas Jefferson, writing to his predecessor, John Adams, 'The day will come when the mystical generation of Jesus, by the Supreme Being as his father, in the womb of a virgin, will be classed with the fable of the gener- ation of Minerva in the brain of Jupiter. '
Dan Brown's novel The Da Vinci Code, and the film made from it, are arousing huge controversy in church circles. Christians are encouraged to boycott the film and picket cinemas that show it. It is indeed fabricated from start to finish: invented, made-up fiction. In that respect, it is exactly like the gospels. The only difference between The Da Vinci Code and the gospels is that the gospels are ancient fiction while The Da Vinci Code is modern fiction.
THE ARGUMENT FROM ADMIRED RELIGIOUS SCIENTISTS
The immense majority of intellectually eminent men disbelieve in Christian religion, but they conceal the fact in public, because they are afraid of losing their incomes.
BERTRAND RUSSELL

apologists even add the name of Darwin, about whom persistent, but demonstrably false, rumours of a deathbed conversion con- tinually come around like a bad smell,* ever since they were deliberately started by a certain 'Lady Hope', who spun a touching yarn of Darwin resting against the pillows in the evening light, leaf- ing through the New Testament and confessing that evolution was all wrong. In this section I shall concentrate mostly on scientists, because - for reasons that are perhaps not too hard to imagine - those who trot out the names of admired individuals as religious exemplars very commonly choose scientists.
Newton did indeed claim to be religious. So did almost every- body until - significantly I think - the nineteenth century, when there was less social and judicial pressure than in earlier centuries to profess religion, and more scientific support for abandoning it. There have been exceptions, of course, in both directions. Even before Darwin, not everybody was a believer, as James Haught shows in his 2000 Years of Disbelief: Famous People with the Courage to Doubt. And some distinguished scientists went on believing after Darwin. We have no reason to doubt Michael Faraday's sincerity as a Christian even after the time when he must have known of Darwin's work. He was a member of the Sandemanian sect, which believed (past tense because they are now virtually extinct) in a literal interpretation of the Bible, ritually washed the feet of newly inducted members and drew lots to deter- mine God's will. Faraday became an Elder in 1860, the year after The Origin of Species was published, and he died a Sandemanian in 1867. The experimentalist Faraday's theorist counterpart, James Clerk Maxwell, was an equally devout Christian. So was that other pillar of nineteenth-century British physics, William Thomson, Lord Kelvin, who tried to demonstrate that evolution was ruled out for lack of time. That great thermodynamicist's erroneous datings assumed that the sun was some kind of fire, burning fuel which would have to run out in tens of millions of years, not thousands of millions. Kelvin obviously could not be expected to know about
* Even I have been honoured by prophecies of deathbed conversion. Indeed, they recur with monotonous regularity (see e. g. Steer 2003), each repetition trailing dewy fresh clouds of illusion that it is witty, and the first. I should probably take the precaution of installing a tape-recorder to protect my posthumous reputation. Lalla Ward adds, 'Why mess around with deathbeds? If you're going to sell out, do it in good time to win the Templeton Prize and blame it on senility. '

nuclear energy. Pleasingly, at the British Association meeting of 1903, it fell to Sir George Darwin, Charles's second son, to vindicate his un-knighted father by invoking the Curies' discovery of radium, and confound the earlier estimate of the still living Lord Kelvin.
Great scientists who profess religion become harder to find through the twentieth century, but they are not particularly rare. I suspect that most of the more recent ones are religious only in the Einsteinian sense which, I argued in Chapter 1, is a misuse of the word. Nevertheless, there are some genuine specimens of good scientists who are sincerely religious in the full, traditional sense. Among contemporary British scientists, the same three names crop up with the likeable familiarity of senior partners in a firm of Dickensian lawyers: Peacocke, Stannard and Polkinghorne. All three have either won the Templeton Prize or are on the Templeton Board of Trustees. After amicable discussions with all of them, both in pub- lic and in private, I remain baffled, not so much by their belief in a cosmic lawgiver of some kind, as by their belief in the details of the Christian religion: resurrection, forgiveness of sins and all.
There are some corresponding examples in the United States, for example Francis Collins, administrative head of the American branch of the official Human Genome Project. * But, as in Britain, they stand out for their rarity and are a subject of amused baffle- ment to their peers in the academic community. In 1996, in the gardens of his old college at Cambridge, Clare, I interviewed my friend Jim Watson, founding genius of the Human Genome Project, for a BBC television documentary that I was making on Gregor Mendel, founding genius of genetics itself. Mendel, of course, was a religious man, an Augustinian monk; but that was in the nine- teenth century, when becoming a monk was the easiest way for the young Mendel to pursue his science. For him, it was the equivalent of a research grant. I asked Watson whether he knew many religious scientists today. He replied: 'Virtually none. Occasionally I meet them, and I'm a bit embarrassed [laughs] because, you know, I can't believe anyone accepts truth by revelation. '
Francis Crick, Watson's co-founder of the whole molecular genetics revolution, resigned his fellowship at Churchill College,
* Not to be confused with the unofficial human genome project, led by that bril- liant (and non-religious) 'buccaneer' of science, Craig Venter.

Cambridge, because of the college's decision to build a chapel (at the behest of a benefactor). In my interview with Watson at Clare, I conscientiously put it to him that, unlike him and Crick, some people see no conflict between science and religion, because they claim science is about how things work and religion is about what it is all for. Watson retorted: 'Well I don't think we're for anything. We're just products of evolution. You can say, "Gee, your life must be pretty bleak if you don't think there's a purpose. " But I'm antic- ipating having a good lunch. ' We did have a good lunch, too.
The efforts of apologists to find genuinely distinguished modern scientists who are religious have an air of desperation, generating the unmistakably hollow sound of bottoms of barrels being scraped. The only website I could find that claimed to list 'Nobel Prize-winning Scientific Christians' came up with six, out of a total of several hundred scientific Nobelists. Of these six, it turned out that four were not Nobel Prize-winners at all; and at least one, to my certain knowledge, is a non-believer who attends church for purely social reasons. A more systematic study by Benjamin Beit- Hallahmi 'found that among Nobel Prize laureates in the sciences, as well as those in literature, there was a remarkable degree of
52 irreligiosity, as compared to the populations they came from'.
A study in the leading journal Nature by Larson and Witham in 1998 showed that of those American scientists considered eminent enough by their peers to have been elected to the National Academy of Sciences (equivalent to being a Fellow of the Royal Society in
53 Britain) only about 7 per cent believe in a personal God. This
overwhelming preponderance of atheists is almost the exact opposite of the profile of the American population at large, of whom more than 90 per cent are believers in some sort of super- natural being. The figure for less eminent scientists, not elected to the National Academy, is intermediate. As with the more distinguished sample, religious believers are in a minority, but a less dramatic minority of about 40 per cent. It is completely as I would expect that American scientists are less religious than the American public generally, and that the most distinguished scientists are the least religious of all. What is remarkable is the polar opposition between the religiosity of the American public at large and the
54 atheism of the intellectual elite.
ARGUMENTS FOR GOD'S EXISTENCE 101
It is faintly amusing that the leading creationist website,
'Answers in Genesis', cites the Larson and Witham study, not in
evidence that there might be something wrong with religion, but as
a weapon in their internal battle against those rival religious
apologists who claim that evolution is compatible with religion.
Under the headline 'National Academy of Science is Godless to the

'Answers in Genesis' is pleased to quote the concluding
Core',
paragraph of Larson and Witham's letter to the editor of Nature:
As we compiled our findings, the NAS [National Academy of Sciences] issued a booklet encouraging the teaching of evolution in public schools, an ongoing source of friction between the scientific community and some conservative Christians in the United States. The booklet assures readers, 'Whether God exists or not is a question about which science is neutral. ' NAS president Bruce Alberts said: 'There are many very outstanding members of this academy who are very religious people, people who believe in evolution, many of them biologists. ' Our survey suggests otherwise.
Alberts, one feels, embraced 'NOMA' for the reasons I discussed in 'The Neville Chamberlain school of evolutionists' (see Chapter 2). 'Answers in Genesis' has a very different agenda.
The equivalent of the US National Academy of Sciences in Britain (and the Commonwealth, including Canada, Australia, New Zealand, India, Pakistan, anglophone Africa, etc. ) is the Royal Society. As this book goes to press, my colleagues R. Elisabeth Cornwell and Michael Stirrat are writing up their comparable, but more thorough, research on the religious opinions of the Fellows of the Royal Society (FRS). The authors' conclusions will be published in full later, but they have kindly allowed me to quote preliminary results here. They used a standard technique for scaling opinion, the Likert-type seven-point scale. All 1,074 Fellows of the Royal Society who possess an email address (the great majority) were polled, and about 23 per cent responded (a good figure for this kind of study). They were offered various propositions, for example: 'I believe in a personal God, that is one who takes an interest in
102 THH G()D DEI. USIGN
individuals, hears and answers prayers, is concerned with sin and transgressions, and passes judgement. ' For each such proposition, they were invited to choose a number from 1 (strong disagreement) to 7 (strong agreement). It is a little hard to compare the results directly with the Larson and Witham study, because Larson and Witham offered their academicians only a three-point scale, not a seven-point scale, but the overall trend is the same. The over- whelming majority of FRS, like the overwhelming majority of US Academicians, are atheists. Only 3. 3 per cent of the Fellows agreed strongly with the statement that a personal god exists (i. e. chose 7 on the scale), while 78. 8 per cent strongly disagreed (i. e. chose 1 on the scale). If you define 'believers' as those who chose 6 or 7, and if you define 'unbelievers' as those who chose 1 or 2, there were a massive 213 unbelievers and a mere 12 believers. Like Larson and Witham, and as also noted by Beit-Hallahmi and Argyle, Cornwell and Stirrat found a small but significant tendency for biological scientists to be even more atheistic than physical scientists. For the details, and all the rest of their very interesting conclusions, please
56 refer to their own paper when it is published.
Moving on from the elite scientists of the National Academy and the Royal Society, is there any evidence that, in the population at large, atheists are likely to be drawn from among the better educated and more intelligent? Several research studies have been published on the statistical relationship between religiosity and educational level, or religiosity and IQ. Michael Shermer, in How We Believe: The Search for God in an Age of Science, describes a large survey of randomly chosen Americans that he and his colleague Frank Sulloway carried out. Among their many interest- ing results was the discovery that religiosity is indeed negatively correlated with education (more highly educated people are less likely to be religious). Religiosity is also negatively correlated with interest in science and (strongly) with political liberalism. None of this is surprising, nor is the fact that there is a positive correlation between religiosity and parents' religiosity. Sociologists studying British children have found that only about one in twelve break away from their parents' religious beliefs.
As you might expect, different researchers measure things in different ways, so it is hard to compare different studies. Meta-
A R G U M E N T S F O R G OD' S E X I S T E N C E 103
analysis is the technique whereby an investigator looks at all the research papers that have been published on a topic, and counts up the number of papers that have concluded one thing, versus the number that have concluded something else. On the subject of religion and IQ, the only meta-analysis known to me was published by Paul Bell in Mensa Magazine in 2002 (Mensa is the society of individuals with a high IQ, and their journal not surprisingly
57 includes articles on the one thing that draws them together). Bell
concluded: 'Of 43 studies carried out since 1927 on the relationship between religious belief and one's intelligence and/or educational level, all but four found an inverse connection. That is, the higher one's intelligence or education level, the less one is likely to be religious or hold "beliefs" of any kind. '
A meta-analysis is almost bound to be less specific than any one of the studies that contributed to it. It would be nice to have more studies along these lines, as well as more studies of the members of elite bodies such as other national academies, and winners of major prizes and medals such as the Nobel, the Crafoord, the Field, the Kyoto, the Cosmos and others. I hope that future editions of this book will include such data. A reasonable conclusion from existing studies is that religious apologists might be wise to keep quieter than they habitually do on the subject of admired role models, at least where scientists are concerned.
PASCAL'S WAGER
The great French mathematician Blaise Pascal reckoned that, how- ever long the odds against God's existence might be, there is an even larger asymmetry in the penalty for guessing wrong. You'd better believe in God, because if you are right you stand to gain eternal bliss and if you are wrong it won't make any difference anyway. On the other hand, if you don't believe in God and you turn out to be wrong you get eternal damnation, whereas if you are right it makes no difference. On the face of it the decision is a no-brainer. Believe in God.
There is something distinctly odd about the argument, however.
104 THE GOD DEIUS1ON
Believing is not something you can decide to do as a matter of policy. At least, it is not something I can decide to do as an act of will. I can decide to go to church and I can decide to recite the Nicene Creed, and I can decide to swear on a stack of bibles that I believe every word inside them. But none of that can make me actually believe it if I don't. Pascal's wager could only ever be an argument for feigning belief in God. And the God that you claim to believe in had better not be of the omniscient kind or he'd see through the deception. The ludicrous idea that believing is something you can decide to do is deliciously mocked by Douglas Adams in Dirk Gently's Holistic Detective Agency, where we meet the robotic Electric Monk, a labour-saving device that you buy 'to do your believing for you'. The de luxe model is advertised as 'Capable of believing things they wouldn't believe in Salt Lake City'.
But why, in any case, do we so readily accept the idea that the one thing you must do if you want to please God is believe in him? What's so special about believing? Isn't it just as likely that God would reward kindness, or generosity, or humility? Or sincerity? What if God is a scientist who regards honest seeking after truth as the supreme virtue? Indeed, wouldn't the designer of the universe have to be a scientist? Bertrand Russell was asked what he would say if he died and found himself confronted by God, demanding to know why Russell had not believed in him. 'Not enough evidence, God, not enough evidence,' was Russell's (I almost said immortal) reply. Mightn't God respect Russell for his courageous scepticism (let alone for the courageous pacifism that landed him in prison in the First World War) far more than he would respect Pascal for his cowardly bet-hedging? And, while we cannot know which way God would jump, we don't need to know in order to refute Pascal's Wager. We are talking about a bet, remember, and Pascal wasn't claiming that his wager enjoyed anything but very long odds. Would you bet on God's valuing dishonestly faked belief (or even honest belief) over honest scepticism?
Then again, suppose the god who confronts you when you die turns out to be Baal, and suppose Baal is just as jealous as his old rival Yahweh was said to be. Mightn't Pascal have been better off wagering on no god at all rather than on the wrong god? Indeed,
A R G U M E N T S F O R G O D ' S E X 1 S T E N C E 105
doesn't the sheer number of potential gods and goddesses on whom one might bet vitiate Pascal's whole logic? Pascal was probably joking when he promoted his wager, just as I am joking in my dis- missal of it. But I have encountered people, for example in the question session after a lecture, who have seriously advanced Pascal's Wager as an argument in favour of believing in God, so it was right to give it a brief airing here.
Is it possible, finally, to argue for a sort of anti-Pascal wager? Suppose we grant that there is indeed some small chance that God exists. Nevertheless, it could be said that you will lead a better, fuller life if you bet on his not existing, than if you bet on his exist- ing and therefore squander your precious time on worshipping him, sacrificing to him, fighting and dying for him, etc. I won't pursue the question here, but readers might like to bear it in mind when we come to later chapters on the evil consequences that can flow from religious belief and observance.
BAYESIAN ARGUMENTS
I think the oddest case I have seen attempted for the existence of God is the Bayesian argument recently put forward by Stephen Unwin in The Probability of God. I hesitated before including this argument, which is both weaker and less hallowed by antiquity than others. Unwin's book, however, received considerable journal- istic attention when it was published in 2003, and it does give the opportunity to bring some explanatory threads together. I have some sympathy with his aims because, as argued in Chapter 2, I believe the existence of God as a scientific hypothesis is, at least in principle, investigable.
Also, Unwin's quixotic attempt to put a number on the probability is quite agreeably funny.
The book's subtitle, A Simple Calculation that Proves the Ultimate Truth, has all the hallmarks of a late addition by the publisher, because such overweening confidence is not to be found in Unwin's text. The book is better seen as a 'How To' manual, a sort of Bayes' Theorem for Dummies, using the existence of God as a semi-facetious case study. Unwin could equally well have used a
106 T H E G O D D E I, U S I O N
hypothetical murder as his test case to demonstrate Bayes' Theorem. The detective marshals the evidence. The fingerprints on the revolver point to Mrs Peacock. Quantify that suspicion by slapping a numerical likelihood on her. However, Professor Plum had a motive to frame her. Reduce the suspicion of Mrs Peacock by a corresponding numerical value. The forensic evidence suggests a 70 per cent likelihood that the revolver was fired accurately from a long distance, which argues for a culprit with military training. Quantify our raised suspicion of Colonel Mustard. The Reverend Green has the most plausible motive for murder. * Increase our numerical assessment of his likelihood. But the long blond hair on the victim's jacket could only belong to Miss Scarlet. . . and so on. A mix of more or less subjectively judged likelihoods churns around in the detective's mind, pulling him in different directions. Bayes' Theorem is supposed to help him to a conclusion. It is a mathe- matical engine for combining many estimated likelihoods and coming up with a final verdict, which bears its own quantitative estimate of likelihood. But of course that final estimate can only be as good as the original numbers fed in. These are usually subjectively judged, with all the doubts that inevitably flow from that. The GIGO principle (Garbage In, Garbage Out) is applicable here - and, in the case of Unwin's God example, applicable is too mild a word.
Unwin is a risk management consultant who carries a torch for Bayesian inference, as against rival statistical methods. He illustrates Bayes' Theorem by taking on, not a murder, but the biggest test case of all, the existence of God. The plan is to start with complete uncertainty, which he chooses to quantify by assign- ing the existence and non-existence of God a 50 per cent starting likelihood each. Then he lists six facts that might bear on the matter, puts a numerical weighting on each, feeds the six numbers into the engine of Bayes' Theorem and sees what number pops out. The trouble is that (to repeat) the six weightings are not measured quantities but simply Stephen Unwin's own personal judgements, turned into numbers for the sake of the exercise. The six facts are:
* The Reverend Green is the character's name in the versions of Cluedo sold in Britain (where the game originated), Australia, New Zealand, India and all other English-speaking areas except North America, where he suddenly becomes Mr Green. What is that all about?

2 People do evil things (Hitler, Stalin, Saddam Hussein).
3 Nature does evil things (earthquakes, tsunamis, hurricanes).
4 There might be minor miracles (I lost my keys and found them again).
5 There might be major miracles (Jesus might have risen from the dead).
6 People have religious experiences.
For what it is worth (nothing, in my opinion), at the end of a ding-dong Bayesian race in which God surges ahead in the betting, then drops way back, then claws his way up to the 50 per cent mark from which he started, he finally ends up enjoying, in Unwin's estimation, a 67 per cent likelihood of existing. Unwin then decides that his Bayesian verdict of 67 per cent isn't high enough, so he takes the bizarre step of boosting it to 95 per cent by an emergency injection of 'faith'. It sounds like a joke, but that really is how he proceeds. I wish I could say how he justifies it, but there really is nothing to say. I have met this kind of absurdity elsewhere, when I have challenged religious but otherwise intelligent scientists to justify their belief, given their admission that there is no evidence: 'I admit that there's no evidence. There's a reason why it's called faith' (this last sentence uttered with almost truculent conviction, and no hint of apology or defensiveness).
Surprisingly, Unwin's list of six statements does not include the argument from design, nor any of Aquinas' five 'proofs', nor any of the various ontological arguments. He has no truck with them: they don't contribute even a minor fillip to his numerical estimate of God's likelihood. He discusses them and, as a good statistician, dis- misses them as empty. I think this is to his credit, although his reason for discounting the design argument is different from mine. But the arguments that he does admit through his Bayesian door are, it seems to me, just as weak. That is only to say that the sub- jective likelihood weightings I would give to them are different from his, and who cares about subjective judgements anyway? He thinks the fact that we have a sense of right and wrong counts
108 T H E G O D D E L U S I O N
strongly in God's favour, whereas I don't see that it should really shift him, in either direction, from his initial prior expectation. Chapters 6 and 7 will show that there is no good case to be made for our possession of a sense of right and wrong having any clear connection with the existence of a supernatural deity. As in the case of our ability to appreciate a Beethoven quartet, our sense of good- ness (though not necessarily our inducement to follow it) would be the way it is with a God and without a God.
On the other hand, Unwin thinks the existence of evil, especially natural catastrophes such as earthquakes and tsunamis, counts strongly against the likelihood that God exists. Here, Unwin's judgement is opposite to mine but goes along with many un- comfortable theologians. 'Theodicy' (the vindication of divine providence in the face of the existence of evil) keeps theologians awake at night. The authoritative Oxford Companion to Philosophy gives the problem of evil as 'the most powerful objection to traditional theism'. But it is an argument only against the existence of a good God. Goodness is no part of the definition of the God Hypothesis, merely a desirable add-on.
Admittedly, people of a theological bent are often chronically incapable of distinguishing what is true from what they'd like to be true. But, for a more sophisticated believer in some kind of super- natural intelligence, it is childishly easy to overcome the problem of evil. Simply postulate a nasty god - such as the one who stalks every page of the Old Testament. Or, if you don't like that, invent a separate evil god, call him Satan, and blame his cosmic battle against the good god for the evil in the world. Or - a more sophisticated solution - postulate a god with grander things to do than fuss about human distress. Or a god who is not indifferent to suffering but regards it as the price that has to be paid for free will in an orderly, lawful cosmos. Theologians can be found buying into all these rationalizations.
For these reasons, if I were redoing Unwin's Bayesian exercise, neither the problem of evil nor moral considerations in general would shift me far, one way or the other, from the null hypothesis (Unwin's 50 per cent). But I don't want to argue the point because, in any case, I can't get excited about personal opinions, whether Unwin's or mine.
A R G U M E N T S F O R G O D ' S E X I S T E N C E 109
There is a much more powerful argument, which does not depend upon subjective judgement, and it is the argument from improbability. It really does transport us dramatically away from 50 per cent agnosticism, far towards the extreme of theism in the view of many theists, far towards the extreme of atheism in my view. I have alluded to it several times already. The whole argument turns on the familiar question 'Who made God? ', which most
thinking people discover for themselves. A designer God cannot be used to explain organized complexity because any God capable of designing anything would have to be complex enough to demand the same kind of explanation in his own right. God presents an infinite regress from which he cannot help us to escape. This argu- ment, as I shall show in the next chapter, demonstrates that God, though not technically disprovable, is very very improbable indeed.
CHAPTER 4 Why there almost certainly is no God

THOMAS JEFFERSON
WHY TIIERE ALMOST CERTAINLY IS NO GOD 113
THE ULTIMATE BOEING 747
The argument from improbability is the big one. In the traditional guise of the argument from design, it is easily today's most popular argument offered in favour of the existence of God and it is seen, by an amazingly large number of theists, as completely and utterly convincing. It is indeed a very strong and, I suspect, unanswerable argument - but in precisely the opposite direction from the theist's intention. The argument from improbability, properly deployed, comes close to proving that God does not exist. My name for the statistical demonstration that God almost certainly does not exist is the Ultimate Boeing 747 gambit.
The name comes from Fred Hoyle's amusing image of the Boeing 747 and the scrapyard. I am not sure whether Hoyle ever wrote it down himself, but it was attributed to him by his close colleague
58 Chandra Wickramasinghe and is presumably authentic. Hoyle
said that the probability of life originating on Earth is no greater than the chance that a hurricane, sweeping through a scrapyard, would have the luck to assemble a Boeing 747. Others have borrowed the metaphor to refer to the later evolution of complex living bodies, where it has a spurious plausibility. The odds against assembling a fully functioning horse, beetle or ostrich by randomly shuffling its parts are up there in 747 territory. This, in a nutshell, is the creationist's favourite argument - an argument that could be made only by somebody who doesn't understand the first thing about natural selection: somebody who thinks natural selection is a theory of chance whereas - in the relevant sense of chance - it is the opposite.
The creationist misappropriation of the argument from im- probability always takes the same general form, and it doesn't make any difference if the creationist chooses to masquerade in the politically expedient fancy dress of 'intelligent design' (ID). * Some observed phenomenon - often a living creature or one of its more complex organs, but it could be anything from a molecule up to the universe itself - is correctly extolled as statistically improbable. Sometimes the language of information theory is used: the Darwinian is challenged to explain the source of all the information
Intelligent design has been unkindly described as creationism in a cheap tuxedo.
114 THE GOD DELUSION
in living matter, in the technical sense of information content as a measure of improbability or 'surprise value'. Or the argument may invoke the economist's hackneyed motto: there's no such thing as a free lunch - and Darwinism is accused of trying to get something for nothing. In fact, as I shall show in this chapter, Darwinian natural selection is the only known solution to the otherwise un- answerable riddle of where the information comes from. It turns out to be the God Hypothesis that tries to get something for nothing. God tries to have his free lunch and be it too. However statistically improbable the entity you seek to explain by invoking a designer, the designer himself has got to be at least as improbable. God is the Ultimate Boeing 747.
The argument from improbability states that complex things could not have come about by chance. But many people define 'come about by chance' as a synonym for 'come about in the absence of deliberate design'. Not surprisingly, therefore, they think improbability is evidence of design. Darwinian natural selection shows how wrong this is with respect to biological improbability. And although Darwinism may not be directly relevant to the inanimate world - cosmology, for example - it raises our consciousness in areas outside its original territory of biology.
A deep understanding of Darwinism teaches us to be wary of the easy assumption that design is the only alternative to chance, and teaches us to seek out graded ramps of slowly increasing complexity. Before Darwin, philosophers such as Hume understood that the improbability of life did not mean it had to be designed, but they couldn't imagine the alternative. After Darwin, we all should feel, deep in our bones, suspicious of the very idea of design. The illusion of design is a trap that has caught us before, and Darwin should have immunized us by raising our consciousness. Would that he had succeeded with all of us.
NATURAL SELECTION AS A CONSCIOUSNESS-RAISER
In a science-fiction starship, the astronauts were homesick: 'Just to
W H Y T H E R E A I . M O S T C E R T A I N L Y I S NO G O D 1 1 5
think that it's springtime back on Earth! ' You may not immediately see what's wrong with this, so deeply ingrained is the unconscious northern hemisphere chauvinism in those of us who live there, and even some who don't. 'Unconscious' is exactly right. That is where consciousness-raising comes in. It is for a deeper reason than gimmicky fun that, in Australia and New Zealand, you can buy maps of the world with the South Pole on top. What splendid consciousness-raisers those maps would be, pinned to the walls of our northern hemisphere classrooms. Day after day, the children would be reminded that 'north' is an arbitrary polarity which has no monopoly on 'up'. The map would intrigue them as well as raise their consciousness. They'd go home and tell their parents - and, by the way, giving children something with which to surprise their
parents is one of the greatest gifts a teacher can bestow.
It was the feminists who raised my consciousness of the power of consciousness-raising. 'Herstory' is obviously ridiculous, if only because the 'his' in 'history' has no etymological connection with the masculine pronoun. It is as etymologically silly as the sacking, in 1999, of a Washington official whose use of 'niggardly' was held to give racial offence. But even daft examples like 'niggardly' or 'herstory' succeed in raising consciousness. Once we have smoothed our philological hackles and stopped laughing, herstory shows us history from a different point of view. Gendered pronouns notoriously are the front line of such consciousness-raising. He or she must ask himself or herself whether his or her sense of style could ever allow himself or herself to write like this. But if we can just get over the clunking infelicity of the language, it raises our consciousness to the sensitivities of half the human race. Man, mankind, the Rights of Man, all men are created equal, one man one vote - English too often seems to exclude woman. * When I was young, it never occurred to me that women might feel slighted by a phrase like 'the future of man'. During the intervening decades, we have all had our consciousness raised. Even those who still use 'man' instead of 'human' do so with an air of self-conscious apology - or truculence, taking a stand for traditional language, even deliberately to rile feminists. All participants in the Zeitgeist
* Classical Latin and Greek were better equipped. Latin homo (Greek anthropo-) means human, as opposed to vir (andro-) which means man, and fetnina (gyne-) which means woman. Thus anthropology pertains to all humanity, where androl- ogy and gynecology are sexually exclusive branches of medicine.
116 THE COD DELUSION
have had their consciousness raised, even those who choose to respond negatively by digging in their heels and redoubling the offence.
Feminism shows us the power of consciousness-raising, and I want to borrow the technique for natural selection. Natural selection not only explains the whole of life; it also raises our consciousness to the power of science to explain how organized complexity can emerge from simple beginnings without any deliberate guidance. A full understanding of natural selection encourages us to move boldly into other fields. It arouses our suspicion, in those other fields, of the kind of false alternatives that once, in pre-Darwinian days, beguiled biology. Who, before Darwin, could have guessed that something so apparently designed as a dragonfly's wing or an eagle's eye was really the end product of a long sequence of non-random but purely natural causes?
Douglas Adams's moving and funny account of his own con- version to radical atheism - he insisted on the 'radical' in case anybody should mistake him for an agnostic - is testimony to the power of Darwinism as a consciousness-raiser. I hope I shall be for- given the self-indulgence that will become apparent in the following quotation. My excuse is that Douglas's conversion by my earlier books - which did not set out to convert anyone - inspired me to dedicate to his memory this book - which does! In an interview, reprinted posthumously in The Salmon of Doubt, he was asked by a journalist how he became an atheist. He began his reply by explaining how he became an agnostic, and then proceeded:
And I thought and thought and thought. But I just didn't have enough to go on, so I didn't really come to any resolution. I was extremely doubtful about the idea of god, but I just didn't know enough about anything to have a good working model of any other explanation for, well, life, the universe, and everything to put in its place. But I kept at it, and I kept reading and I kept thinking. Sometime around my early thirties I stumbled upon evolutionary biology, particularly in the form of Richard Dawkins's books The Selfish Gene and then The Blind Watchmaker, and suddenly (on, I think the second
W H Y T H E R E A L . M O S T C E R T A I N L . Y I S NO G O D
1 1 7
reading of The Selfish Gene) it all fell into place. It was a concept of such stunning simplicity, but it gave rise, naturally, to all of the infinite and baffling complexity of life. The awe it inspired in me made the awe that people talk about in respect of religious experience seem, frankly, silly beside it. I'd take the awe of understanding over the
59 awe of ignorance any day.
The concept of stunning simplicity that he was talking about was, of course, nothing to do with me. It was Darwin's theory of evolution by natural selection - the ultimate scientific consciousness- raiser. Douglas, I miss you. You are my cleverest, funniest, most open-minded, wittiest, tallest, and possibly only convert. I hope this book might have made you laugh - though not as much as you made me.
That scientifically savvy philosopher Daniel Dennett pointed out that evolution counters one of the oldest ideas we have: 'the idea that it takes a big fancy smart thing to make a lesser thing. I call that the trickle-down theory of creation. You'll never see a spear making a spear maker. You'll never see a horse shoe making
60
a blacksmith. You'll never see a pot making a potter. '
discovery of a workable process that does that very counter- intuitive thing is what makes his contribution to human thought so revolutionary, and so loaded with the power to raise consciousness.
It is surprising how necessary such consciousness-raising is, even in the minds of excellent scientists in fields other than biology. Fred Hoyle was a brilliant physicist and cosmologist, but his Boeing 747 misunderstanding, and other mistakes in biology such as his attempt to dismiss the fossil Archaeopteryx as a hoax, suggest that he needed to have his consciousness raised by some good exposure to the world of natural selection. At an intellectual level, I suppose he understood natural selection. But perhaps you need to be steeped in natural selection, immersed in it, swim about in it, before you can truly appreciate its power.
Other sciences raise our consciousness in different ways. Fred Hoyle's own science of astronomy puts us in our place, meta- phorically as well as literally, scaling down our vanity to fit the tiny stage on which we play out our lives - our speck of debris from the
Darwin's
118 THE GOD DELUSION
cosmic explosion. Geology reminds us of our brief existence both as individuals and as a species. It raised John Ruskin's conscious- ness and provoked his memorable heart cry of 1851: 'If only the Geologists would let me alone, I could do very well, but those dreadful hammers! I hear the clink of them at the end of every cadence of the Bible verses. ' Evolution does the same thing for our sense of time - not surprisingly, since it works on the geological timescale. But Darwinian evolution, specifically natural selection, does something more. It shatters the illusion of design within the domain of biology, and teaches us to be suspicious of any kind of design hypothesis in physics and cosmology as well. I think the physicist Leonard Susskind had this in mind when he wrote, 'I'm not an historian but I'll venture an opinion: Modern cosmology really began with Darwin and Wallace. Unlike anyone before them, they provided explanations of our existence that completely rejected supernatural agents . . . Darwin and Wallace set a standard
61
not only for the life sciences but for cosmology as well. ' Other
physical scientists who are far above needing any such consciousness-raising are Victor Stenger, whose book Has Science Found God? (the answer is no) I strongly recommend, and Peter Atkins, whose Creation Revisited is my favourite work of scientific prose poetry.
I am continually astonished by those theists who, far from having their consciousness raised in the way that I propose, seem to rejoice in natural selection as 'God's way of achieving his creation'. They note that evolution by natural selection would be a very easy and neat way to achieve a world full of life. God wouldn't need to do anything at all! Peter Atkins, in the book just mentioned, takes this line of thought to a sensibly godless conclusion when he postulates a hypothetically lazy God who tries to get away with as little as possible in order to make a universe containing life. Atkins's lazy God is even lazier than the deist God of the eighteenth-century Enlightenment: deus otiosus - literally God at leisure, unoccupied, unemployed, superfluous, useless. Step by step, Atkins succeeds in reducing the amount of work the lazy God has to do until he finally ends up doing nothing at all: he might as well not bother to exist. My memory vividly hears Woody Allen's perceptive whine: 'If it turns out that there is a God, I don't think that he's evil. But the

worst that you can say about him is that basically he's an under- achiever. '
IRREDUCIBLE COMPLEXITY
It is impossible to exaggerate the magnitude of the problem that Darwin and Wallace solved. I could mention the anatomy, cellular structure, biochemistry and behaviour of literally any living organism by example. But the most striking feats of apparent design are those picked out - for obvious reasons - by creationist authors, and it is with gentle irony that I derive mine from a creationist book. Life - How Did It Get Here? , with no named author but published by the Watchtower Bible and Tract Society in sixteen languages and eleven million copies, is obviously a firm favourite because no fewer than six of those eleven million copies have been sent to me as unsolicited gifts by well-wishers from around the world.
Picking a page at random from this anonymous and lavishly dis- tributed work, we find the sponge known as Venus' Flower Basket (Euplectella), accompanied by a quotation from Sir David Attenborough, no less: 'When you look at a complex sponge skeleton such as that made of silica spicules which is known as Venus' Flower Basket, the imagination is baffled. How could quasi- independent microscopic cells collaborate to secrete a million glassy splinters and construct such an intricate and beautiful lattice? We do not know.
