The God Delusion Page 7

  What the theist claims about God is that he does have a power to create, conserve, or annihilate anything, big or small. And he can also make objects move or do anything else . . . He can make the planets move in the way that Kepler discovered that they move, or make gunpowder explode when we set a match to it; or he can make planets move in quite different ways, and chemical substances explode or not explode under quite different conditions from those which now govern their behaviour. God is not limited by the laws of nature; he makes them and he can change or suspend them - if he chooses.

  Just too easy, isn't it! Whatever else this is, it is very far from NOMA. And whatever else they may say, those scientists who subscribe to the 'separate magisteria' school of thought should concede that a universe with a supernaturally intelligent creator is a very different kind of universe from one without. The difference between the two hypothetical universes could hardly be more fundamental in principle, even if it is not easy to test in practice. And it undermines the complacently seductive dictum that science must be completely silent about religion's central existence claim. The presence or absence of a creative super-intelligence is unequivocally a scientific question, even if it is not in practice - or not yet - a decided one. So also is the truth or falsehood of every one of the miracle stories that religions rely upon to impress multitudes of the faithful.

  Did Jesus have a human father, or was his mother a virgin at the time of his birth? Whether or not there is enough surviving evidence to decide it, this is still a strictly scientific question with a definite answer in principle: yes or no. Did Jesus raise Lazarus from the dead? Did he himself come alive again, three days after being crucified? There is an answer to every such question, whether or not we can discover it in practice, and it is a strictly scientific answer. The methods we should use to settle the matter, in the unlikely event that relevant evidence ever became available, would be purely and entirely scientific methods. To dramatize the point, imagine, by some remarkable set of circumstances, that forensic archaeologists unearthed DNA evidence to show that Jesus really did lack a biological father. Can you imagine religious apologists shrugging their shoulders and saying anything remotely like the following? 'Who cares? Scientific evidence is completely irrelevant to theological questions. Wrong magisterium! We're concerned only with ultimate questions and with moral values. Neither DNA nor any other scientific evidence could ever have any bearing on the matter, one way or the other.'

  The very idea is a joke. You can bet your boots that the scientific evidence, if any were to turn up, would be seized upon and trumpeted to the skies. NOMA is popular only because there is no evidence to favour the God Hypothesis. The moment there was the smallest suggestion of any evidence in favour of religious belief, religious apologists would lose no time in throwing NOMA out of the window. Sophisticated theologians aside (and even they are happy to tell miracle stories to the unsophisticated in order to swell congregations), I suspect that alleged miracles provide the strongest reason many believers have for their faith; and miracles, by definition, violate the principles of science.

  The Roman Catholic Church on the one hand seems sometimes to aspire to NOMA, but on the other hand lays down the performance of miracles as an essential qualification for elevation to sainthood. The late King of the Belgians is a candidate for sainthood, because of his stand on abortion. Earnest investigations are now going on to discover whether any miraculous cures can be attributed to prayers offered up to him since his death. I am not joking. That is the case, and it is typical of saint stories. I imagine the whole business is an embarrassment to more sophisticated circles within the Church. Why any circles worthy of the name of sophisticated remain within the Church is a mystery at least as deep as those that theologians enjoy.

  When faced with miracle stories, Gould would presumably retort along the following lines. The whole point of NOMA is that it is a two-way bargain. The moment religion steps on science's turf and starts to meddle in the real world with miracles, it ceases to be religion in the sense Gould is defending, and his amicabilis concordia is broken. Note, however, that the miracle-free religion defended by Gould would not be recognized by most practising theists in the pew or on the prayer mat. It would, indeed, be a grave disappointment to them. To adapt Alice's comment on her sister's book before she fell into Wonderland, what is the use of a God who does no miracles and answers no prayers? Remember Ambrose Bierce's witty definition of the verb 'to pray': 'to ask that the laws of the universe be annulled in behalf of a single petitioner, confessedly unworthy'. There are athletes who believe God helps them win - against opponents who would seem, on the face of it, no less worthy of his favouritism. There are motorists who believe God saves them a parking space - thereby presumably depriving somebody else. This style of theism is embarrassingly popular, and is unlikely to be impressed by anything as (superficially) reasonable as NOMA.

  Nevertheless, let us follow Gould and pare our religion down to some sort of non-interventionist minimum: no miracles, no personal communication between God and us in either direction, no monkeying with the laws of physics, no trespassing on the scientific grass. At most, a little deistic input to the initial conditions of the universe so that, in the fullness of time, stars, elements, chemistry and planets develop, and life evolves. Surely that is an adequate separation? Surely NOMA can survive this more modest and unassuming religion?

  Well, you might think so. But I suggest that even a non-interventionist, NOMA God, though less violent and clumsy than an Abrahamic God, is still, when you look at him fair and square, a scientific hypothesis. I return to the point: a universe in which we are alone except for other slowly evolved intelligences is a very different universe from one with an original guiding agent whose intelligent design is responsible for its very existence. I accept that it may not be so easy in practice to distinguish one kind of universe from the other. Nevertheless, there is something utterly special about the hypothesis of ultimate design, and equally special about the only known alternative: gradual evolution in the broad sense. They are close to being irreconcilably different. Like nothing else, evolution really does provide an explanation for the existence of entities whose improbability would otherwise, for practical purposes, rule them out. And the conclusion to the argument, as I shall show in Chapter 4, is close to being terminally fatal to the God Hypothesis.

  THE GREAT PRAYER EXPERIMENT

  An amusing, if rather pathetic, case study in miracles is the Great Prayer Experiment: does praying for patients help them recover? Prayers are commonly offered for sick people, both privately and in formal places of worship. Darwin's cousin Francis Galton was the first to analyse scientifically whether praying for people is efficacious. He noted that every Sunday, in churches throughout Britain, entire congregations prayed publicly for the health of the royal family. Shouldn't they, therefore, be unusually fit, compared with the rest of us, who are prayed for only by our nearest and dearest?* Galton looked into it, and found no statistical difference. His intention may, in any case, have been satirical, as also when he prayed over randomized plots of land to see if the plants would grow any faster (they didn't).

  * When my Oxford college elected the Warden whom I quoted earlier, it happened that the Fellows publicly drank his health on three successive evenings. At the third of these dinners, he graciously remarked in his speech of reply: 'I'm feeling better already.'

  More recently, the physicist Russell Stannard (one of Britain's three well-known religious scientists, as we shall see) has thrown his weight behind an initiative, funded by - of course - the Templeton Foundation, to test experimentally the proposition that praying for sick patients improves their health.36

  Such experiments, if done properly, have to be double blind, and this standard was strictly observed. The patients were assigned, strictly at random, to an experimental group (received prayers) or a control group (received no prayers). Neither the patients, nor their doctors or caregivers, nor the experimenters were allowed to kn
ow which patients were being prayed for and which patients were controls. Those who did the experimental praying had to know the names of the individuals for whom they were praying -otherwise, in what sense would they be praying for them rather than for somebody else? But care was taken to tell them only the first name and initial letter of the surname. Apparently that would be enough to enable God to pinpoint the right hospital bed.

  The very idea of doing such experiments is open to a generous measure of ridicule, and the project duly received it. As far as I know, Bob Newhart didn't do a sketch about it, but I can distinctly hear his voice:

  What's that you say, Lord? You can't cure me because I'm a member of the control group? . . . Oh I see, my aunt's prayers aren't enough. But Lord, Mr Evans in the next-door bed .. . What was that, Lord? . . . Mr Evans received a thousand prayers per day? But Lord, Mr Evans doesn't know a thousand people . . . Oh, they just referred to him as John E. But Lord, how did you know they didn't mean John Ellsworthy? . . . Oh right, you used your omniscience to work out which John E they meant. But Lord . . .

  Valiantly shouldering aside all mockery, the team of researchers soldiered on, spending $2.4 million of Templeton money under the leadership of Dr Herbert Benson, a cardiologist at the Mind/Body Medical Institute near Boston. Dr Benson was earlier quoted in a Templeton press release as 'believing that evidence for the efficacy of intercessory prayer in medicinal settings is mounting'. Reassuringly, then, the research was in good hands, unlikely to be spoiled by sceptical vibrations. Dr Benson and his team monitored 1,802 patients at six hospitals, all of whom received coronary bypass surgery. The patients were divided into three groups. Group 1 received prayers and didn't know it. Group 2 (the control group) received no prayers and didn't know it. Group 3 received prayers and did know it. The comparison between Groups 1 and 2 tests for the efficacy of intercessory prayer. Group 3 tests for possible psychosomatic effects of knowing that one is being prayed for.

  Prayers were delivered by the congregations of three churches, one in Minnesota, one in Massachusetts and one in Missouri, all distant from the three hospitals. The praying individuals, as explained, were given only the first name and initial letter of the surname of each patient for whom they were to pray. It is good experimental practice to standardize as far as possible, and they were all, accordingly, told to include in their prayers the phrase 'for a successful surgery with a quick, healthy recovery and no complications'.

  The results, reported in the American Heart Journal of April 2006, were clear-cut. There was no difference between those patients who were prayed for and those who were not. What a surprise. There was a difference between those who knew they had been prayed for and those who did not know one way or the other; but it went in the wrong direction. Those who knew they had been the beneficiaries of prayer suffered significantly more complications than those who did not. Was God doing a bit of smiting, to show his disapproval of the whole barmy enterprise? It seems more probable that those patients who knew they were being prayed for suffered additional stress in consequence: 'performance anxiety', as the experimenters put it. Dr Charles Bethea, one of the researchers, said, 'It may have made them uncertain, wondering am I so sick they had to call in their prayer team?' In today's litigious society, is it too much to hope that those patients suffering heart complications, as a consequence of knowing they were receiving experimental prayers, might put together a class action lawsuit against the Templeton Foundation?

  It will be no surprise that this study was opposed by theologians, perhaps anxious about its capacity to bring ridicule upon religion. The Oxford theologian Richard Swinburne, writing after the study failed, objected to it on the grounds that God answers prayers only if they are offered up for good reasons.37 Praying for somebody rather than somebody else, simply because of the fall of the dice in the design of a double-blind experiment, does not constitute a good reason. God would see through it. That, indeed, was the point of my Bob Newhart satire, and Swinburne is right to make it too. But in other parts of his paper Swinburne himself is beyond satire. Not for the first time, he seeks to justify suffering in a world run by God:

  My suffering provides me with the opportunity to show courage and patience. It provides you with the opportunity to show sympathy and to help alleviate my suffering. And it provides society with the opportunity to choose whether or not to invest a lot of money in trying to find a cure for this or that particular kind of suffering . . . Although a good God regrets our suffering, his greatest concern is surely that each of us shall show patience, sympathy and generosity and, thereby, form a holy character. Some people badly need to be ill for their own sake, and some people badly need to be ill to provide important choices for others. Only in that way can some people be encouraged to make serious choices about the sort of person they are to be. For other people, illness is not so valuable.

  This grotesque piece of reasoning, so damningly typical of the theological mind, reminds me of an occasion when I was on a television panel with Swinburne, and also with our Oxford colleague Professor Peter Atkins. Swinburne at one point attempted to justify the Holocaust on the grounds that it gave the Jews a wonderful opportunity to be courageous and noble. Peter Atkins splendidly growled, 'May you rot in hell.'*

  * This interchange was edited out of the final broadcast version. That Swinburne's remark is typical of his theology is indicated by his rather similar comment about Hiroshima in The Existence of God (2004), page 264: 'Suppose that one less person had been burnt by the Hiroshima atomic bomb. Then there would have been less opportunity for courage and sympathy . . .'

  Another typical piece of theological reasoning occurs further along in Swinburne's article. He rightly suggests that if God wanted to demonstrate his own existence he would find better ways to do it than slightly biasing the recovery statistics of experimental versus control groups of heart patients. If God existed and wanted to convince us of it, he could 'fill the world with super-miracles'. But then Swinburne lets fall his gem: 'There is quite a lot of evidence anyway of God's existence, and too much might not be good for us.' Too much might not be good for us! Read it again. Too much evidence might not be good for us. Richard Swinburne is the recently retired holder of one of Britain's most prestigious professorships of theology, and is a Fellow of the British Academy. If it's a theologian you want, they don't come much more distinguished. Perhaps you don't want a theologian.

  Swinburne wasn't the only theologian to disown the study after it had failed. The Reverend Raymond J. Lawrence was granted a generous tranche of op-ed space in the New York Times to explain why responsible religious leaders 'will breathe a sigh of relief that no evidence could be found of intercessory prayer having any effect.38 Would he have sung a different tune if the Benson study had succeeded in demonstrating the power of prayer? Maybe not, but you can be certain that plenty of other pastors and theologians would. The Reverend Lawrence's piece is chiefly memorable for the following revelation: 'Recently, a colleague told me about a devout, well-educated woman who accused a doctor of malpractice in his treatment of her husband. During her husband's dying days, she charged, the doctor had failed to pray for him.'

  Other theologians joined NOMA-inspired sceptics in contending that studying prayer in this way is a waste of money because supernatural influences are by definition beyond the reach of science. But as the Templeton Foundation correctly recognized when it financed the study, the alleged power of intercessory prayer is at least in principle within the reach of science. A double-blind experiment can be done and was done. It could have yielded a positive result. And if it had, can you imagine that a single religious apologist would have dismissed it on the grounds that scientific research has no bearing on religious matters? Of course not.

  Needless to say, the negative results of the experiment will not shake the faithful. Bob Barth, the spiritual director of the Missouri prayer ministry which supplied some of the experimental prayers, said: 'A person of faith would say that this study is interesting,
but we've been praying a long time and we've seen prayer work, we know it works, and the research on prayer and spirituality is just getting started.' Yeah, right: we know from our faith that prayer works, so if evidence fails to show it we'll just soldier on until finally we get the result we want.

  THE NEVILLE CHAMBERLAIN SCHOOL OF EVOLUTIONISTS

  A possible ulterior motive for those scientists who insist on NOMA - the invulnerability to science of the God Hypothesis - is a peculiarly American political agenda, provoked by the threat of populist creationism. In parts of the United States, science is under attack from a well-organized, politically well-connected and, above all, well-financed opposition, and the teaching of evolution is in the front-line trench. Scientists could be forgiven for feeling threatened, because most research money comes ultimately from government, and elected representatives have to answer to the ignorant and prejudiced, as well as to the well-informed, among their constituents. In response to such threats, an evolution defence lobby has sprung up, most notably represented by the National Center for Science Education (NCSE), led by Eugenie Scott, indefatigable activist on behalf of science who has recently produced her own book, Evolution vs. Creationism. One of NCSE's main political objectives is to court and mobilize 'sensible' religious opinion: mainstream churchmen and women who have no problem with evolution and may regard it as irrelevant to (or even in some strange way supportive of) their faith. It is to this mainstream of clergy, theologians and non-fundamentalist believers, embarrassed as they are by creationism because it brings religion into disrepute, that the evolution defence lobby tries to appeal. And one way to do this is to bend over backwards in their direction by espousing NOMA - agree that science is completely non-threatening, because it is disconnected from religion's claims.
