The God Delusion, Page 9

  4. The Argument from Degree. We notice that things in the world differ. There are degrees of, say, goodness or perfection. But we judge these degrees only by comparison with a maximum. Humans can be both good and bad, so the maximum goodness cannot rest in us. Therefore there must be some other maximum to set the standard for perfection, and we call that maximum God.

  That's an argument? You might as well say, people vary in smelli-ness but we can make the comparison only by reference to a perfect maximum of conceivable smelliness. Therefore there must exist a pre-eminently peerless stinker, and we call him God. Or substitute any dimension of comparison you like, and derive an equivalently fatuous conclusion.

  5. The Teleological Argument, or Argument from Design. Things in the world, especially living things, look as though they have been designed. Nothing that we know looks designed unless it is designed. Therefore there must have been a designer, and we call him God.* Aquinas himself used the analogy of an arrow moving towards a target, but a modern heat-seeking anti-aircraft missile would have suited his purpose better.

  The argument from design is the only one still in regular use today, and it still sounds to many like the ultimate knockdown argument. The young Darwin was impressed by it when, as a Cambridge undergraduate, he read it in William Paley's Natural Theology. Unfortunately for Paley, the mature Darwin blew it out of the water. There has probably never been a more devastating rout of popular belief by clever reasoning than Charles Darwin's destruction of the argument from design. It was so unexpected. Thanks to Darwin, it is no longer true to say that nothing that we know looks designed unless it is designed. Evolution by natural selection produces an excellent simulacrum of design, mounting prodigious heights of complexity and elegance. And among these eminences of pseudo-design are nervous systems which - among their more modest accomplishments - manifest goal-seeking behaviour that, even in a tiny insect, resembles a sophisticated heat-seeking missile more than a simple arrow on target. I shall return to the argument from design in Chapter 4.

  * I cannot help being reminded of the immortal syllogism that was smuggled into a Euclidean proof by a schoolfriend, when we were studying geometry together: 'Triangle ABC looks isosceles. Therefore . . .'

  THE ONTOLOGICAL ARGUMENT AND OTHER A PRIORI ARGUMENTS

  Arguments for God's existence fall into two main categories, the a priori and the a posteriori. Thomas Aquinas' five are a posteriori arguments, relying upon inspection of the world. The most famous of the a priori arguments, those that rely upon pure armchair ratiocination, is the ontological argument, proposed by St Anselm of Canterbury in 1078 and restated in different forms by numerous philosophers ever since. An odd aspect of Anselm's argument is that it was originally addressed not to humans but to God himself, in the form of a prayer (you'd think that any entity capable of listening to a prayer would need no convincing of his own existence).

  It is possible to conceive, Anselm said, of a being than which nothing greater can be conceived. Even an atheist can conceive of such a superlative being, though he would deny its existence in the real world. But, goes the argument, a being that doesn't exist in the real world is, by that very fact, less than perfect. Therefore we have a contradiction and, hey presto, God exists!

  Let me translate this infantile argument into the appropriate language, which is the language of the playground:

  'Bet you I can prove God exists.'

  'Bet you can't.'

  'Right then, imagine the most perfect perfect perfect thing possible.'

  'Okay, now what?'

  'Now, is that perfect perfect perfect thing real? Does it exist?'

  'No, it's only in my mind.'

  'But if it was real it would be even more perfect, because a really really perfect thing would have to be better than a silly old imaginary thing. So I've proved that God exists. Nur Nurny Nur Nur. All atheists are fools.'

  I had my childish wiseacre choose the word 'fools' advisedly. Anselm himself quoted the first verse of Psalm 14, 'The fool hath said in his heart, There is no God,' and he had the cheek to use the name 'fool' (Latin insipiens) for his hypothetical atheist:

  Hence, even the fool is convinced that something exists in the understanding, at least, than which nothing greater can be conceived. For, when he hears of this, he understands it. And whatever is understood, exists in the understanding. And assuredly that, than which nothing greater can be conceived, cannot exist in the understanding alone. For, suppose it exists in the understanding alone: then it can be conceived to exist in reality; which is greater.

  The very idea that grand conclusions could follow from such logo-machist trickery offends me aesthetically, so I must take care to refrain from bandying words like 'fool'. Bertrand Russell (no fool) interestingly said, 'It is easier to feel convinced that [the ontological argument] must be fallacious than it is to find out precisely where the fallacy lies.' Russell himself, as a young man, was briefly convinced by it:

  I remember the precise moment, one day in 1894, as I was walking along Trinity Lane, when I saw in a flash (or thought I saw) that the ontological argument is valid. I had gone out to buy a tin of tobacco; on my way back, I suddenly threw it up in the air, and exclaimed as I caught it: 'Great Scott, the ontological argument is sound.'

  Why, I wonder, didn't he say something like: 'Great Scott, the ontological argument seems to be plausible. But isn't it too good to be true that a grand truth about the cosmos should follow from a mere word game? I'd better set to work to resolve what is perhaps a paradox like those of Zeno.' The Greeks had a hard time seeing through Zeno's 'proof that Achilles would never catch the tortoise.* But they had the sense not to conclude that therefore Achilles really would fail to catch the tortoise. Instead, they called it a paradox and waited for later generations of mathematicians to explain it (with, as it turned out, the theory of infinite series converging on a limiting value). Russell himself, of course, was as well qualified as anyone to understand why no tobacco tins should be thrown up in celebration of Achilles' failure to catch the tortoise. Why didn't he exercise the same caution over St Anselm? I suspect that he was an exaggeratedly fair-minded atheist, over-eager to be disillusioned if logic seemed to require it.* Or perhaps the answer lies in something Russell himself wrote in 1946, long after he had rumbled the ontological argument:

  * Zeno's paradox is too well known for the details to be promoted out of a footnote. Achilles can run ten times as fast as the tortoise, so he gives the animal, say, 100 yards' start. Achilles runs 100 yards, and the tortoise is now 10 yards ahead. Achilles runs the 10 yards and the tortoise is now 1 yard ahead. Achilles runs the 1 yard, and the tortoise is still a tenth of a yard ahead . . . and so on ad infinitum, so Achilles never catches the tortoise.

  * We might be seeing something similar today in the over-publicized tergiversation of the philosopher Antony Flew, who announced in his old age that he had been converted to belief in some sort of deity (triggering a frenzy of eager repetition all around the Internet). On the other hand, Russell was a great philosopher. Russell won the Nobel Prize. Maybe Flew's alleged conversion will be rewarded with the Templeton Prize. A first step in that direction is his ignominious decision to accept, in 2006, the 'Phillip E. Johnson Award for Liberty and Truth'. The first holder of the Phillip E. Johnson Award was Phillip E. Johnson, the lawyer credited with founding the Intelligent Design 'wedge strategy'. Flew will be the second holder. The awarding university is BIOLA, the Bible Institute of Los Angeles. One can't help wondering whether Flew realizes that he is being used. See Victor Stenger, 'Flew's flawed science', Free Inquiry 25: 2, 2005, 17-18; www.secularhumanism.org/index.php ?section=library&page=stenger_25_2.

  The real question is: Is there anything we can think of which, by the mere fact that we can think of it, is shown to exist outside our thought? Every philosopher would like to say yes, because a philosopher's job is to find out things about the world by thinking rather than observing. If yes is the right answer, there is a bridge from pure thought to
things. If not, not.

  My own feeling, to the contrary, would have been an automatic, deep suspicion of any line of reasoning that reached such a significant conclusion without feeding in a single piece of data from the real world. Perhaps that indicates no more than that I am a scientist rather than a philosopher. Philosophers down the centuries have indeed taken the ontological argument seriously, both for and against. The atheist philosopher J. L. Mackie gives a particularly clear discussion in The Miracle of Theism. I mean it as a compliment when I say that you could almost define a philosopher as someone who won't take common sense for an answer.

  The most definitive refutations of the ontological argument are usually attributed to the philosophers David Hume (1711-76) and Immanuel Kant (1724-1804). Kant identified the trick card up Anselm's sleeve as his slippery assumption that 'existence' is more 'perfect' than non-existence. The American philosopher Norman Malcolm put it like this: 'The doctrine that existence is a perfection is remarkably queer. It makes sense and is true to say that my future house will be a better one if it is insulated than if it is not insulated; but what could it mean to say that it will be a better house if it exists than if it does not?'46 Another philosopher, the Australian Douglas Gasking, made the point with his ironic 'proof that God does not exist (Anselm's contemporary Gaunilo had suggested a somewhat similar reductio).

  1. The creation of the world is the most marvellous achievement imaginable.

  2. The merit of an achievement is the product of (a) its intrinsic quality, and (b) the ability of its creator.

  3. The greater the disability (or handicap) of the creator, the more impressive the achievement.

  4. The most formidable handicap for a creator would be non-existence.

  5. Therefore if we suppose that the universe is the product of an existent creator we can conceive a greater being - namely, one who created everything while not existing.

  6. An existing God therefore would not be a being greater than which a greater cannot be conceived because an even more formidable and incredible creator would be a God which did not exist.

  Ergo:

  7. God does not exist.

  Needless to say, Gasking didn't really prove that God does not exist. By the same token, Anselm didn't prove that he does. The only difference is, Gasking was being funny on purpose. As he realized, the existence or non-existence of God is too big a question to be decided by 'dialectical prestidigitation'. And I don't think the slippery use of existence as an indicator of perfection is the worst of the argument's problems. I've forgotten the details, but I once piqued a gathering of theologians and philosophers by adapting the ontological argument to prove that pigs can fly. They felt the need to resort to Modal Logic to prove that I was wrong.

  The ontological argument, like all a priori arguments for the existence of God, reminds me of the old man in Aldous Huxley's Point Counter Point who discovered a mathematical proof of the existence of God:

  You know the formula, m over nought equals infinity, m being any positive number? Well, why not reduce the equation to a simpler form by multiplying both sides by nought. In which case you have m equals infinity times nought. That is to say that a positive number is the product of zero and infinity. Doesn't that demonstrate the creation of the universe by an infinite power out of nothing? Doesn't it?

  Or there is the notorious eighteenth-century debate on the existence of God, staged by Catherine the Great between Euler, the Swiss mathematician, and Diderot, the great encyclopedist of the Enlightenment. The pious Euler advanced upon the atheistic Diderot and, in tones of the utmost conviction, delivered his challenge: 'Monsieur, (a + b")/n = x, therefore God exists. Reply!' Diderot was cowed into withdrawal, and one version of the story has him withdrawing all the way back to France.

  Euler was employing what might be called the Argument from Blinding with Science (in this case mathematics). David Mills, in Atheist Universe, transcribes a radio interview of himself by a religious spokesman, who invoked the Law of Conservation of Mass-Energy in a weirdly ineffectual attempt to blind with science: 'Since we're all composed of matter and energy, doesn't that scientific principle lend credibility to a belief in eternal life?' Mills replied more patiently and politely than I would have, for what the interviewer was saying, translated into English, was no more than: 'When we die, none of the atoms of our body (and none of the energy) are lost. Therefore we are immortal.'

  Even I, with my long experience, have never encountered wishful thinking as silly as that. I have, however, met many of the wonderful 'proofs' collected at http://www.godlessgeeks.com/LINKS/ GodProof.htm, a richly comic numbered list of 'Over Three Hundred Proofs of God's Existence'. Here's a hilarious half-dozen, beginning with Proof Number 36.

  36. Argument from Incomplete Devastation: A plane crashed killing 143 passengers and crew. But one child survived with only third-degree burns. Therefore God exists.

  37. Argument from Possible Worlds: If things had been different, then things would be different. That would be bad. Therefore God exists.

  38. Argument from Sheer Will: I do believe in God! I do believe in God! I do I do I do. I do believe in God! Therefore God exists.

  39. Argument from Non-belief: The majority of the world's population are non-believers in Christianity. This is just what Satan intended. Therefore God exists.

  40. Argument from Post-Death Experience: Person X died an atheist. He now realizes his mistake. Therefore God exists.

  41. Argument from Emotional Blackmail: God loves you. How could you be so heartless as not to believe in him? Therefore God exists.

  THE ARGUMENT FROM BEAUTY

  Another character in the Aldous Huxley novel just mentioned proved the existence of God by playing Beethoven's string quartet no. 15 in A minor {'heiliger Dankgesang') on a gramophone. Unconvincing as that sounds, it does represent a popular strand of argument. I have given up counting the number of times I receive the more or less truculent challenge: 'How do you account for Shakespeare, then?' (Substitute Schubert, Michelangelo, etc. to taste.) The argument will be so familiar, I needn't document it further. But the logic behind it is never spelled out, and the more you think about it the more vacuous you realize it to be. Obviously Beethoven's late quartets are sublime. So are Shakespeare's sonnets. They are sublime if God is there and they are sublime if he isn't. They do not prove the existence of God; they prove the existence of Beethoven and of Shakespeare. A great conductor is credited with saying: 'If you have Mozart to listen to, why would you need God?'

  I once was the guest of the week on a British radio show called Desert Island Discs. You have to choose the eight records you would take with you if marooned on a desert island. Among my choices was 'Mache dich mein Herze rein' from Bach's St Matthew Passion. The interviewer was unable to understand how I could choose religious music without being religious. You might as well say, how can you enjoy Wuthering Heights when you know perfectly well that Cathy and Heathcliff never really existed?

  But there is an additional point that I might have made, and which needs to be made whenever religion is given credit for, say, the Sistine Chapel or Raphael's Annunciation. Even great artists have to earn a living, and they will take commissions where they are to be had. I have no reason to doubt that Raphael and Michelangelo were Christians - it was pretty much the only option in their time - but the fact is almost incidental. Its enormous wealth had made the Church the dominant patron of the arts. If history had worked out differently, and Michelangelo had been commissioned to paint a ceiling for a giant Museum of Science, mightn't he have produced something at least as inspirational as the Sistine Chapel? How sad that we shall never hear Beethoven's Mesozoic Symphony, or Mozart's opera The Expanding Universe.

  And what a shame that we are deprived of Haydn's Evolution Oratorio - but that does not stop us from enjoying his Creation. To approach the argument from the other side, what if, as my wife chillingly suggests to me, Shakespeare had been obliged to work to commissions from the Church? We'd
surely have lost Hamlet, King Lear and Macbeth. And what would we have gained in return? Such stuff as dreams are made on? Dream on.

  If there is a logical argument linking the existence of great art to the existence of God, it is not spelled out by its proponents. It is simply assumed to be self-evident, which it most certainly is not. Maybe it is to be seen as yet another version of the argument from design: Schubert's musical brain is a wonder of improbability, even more so than the vertebrate's eye. Or, more ignobly, perhaps it's a sort of jealousy of genius. How dare another human being make such beautiful music/poetry/art, when I can't? It must be God that did it.
