William Lane Craig's Cock-Up.

Here's a fascinating example of how William Lane Craig tries to bamboozles his lay audience with highly technical arguments and how he relies on their ignorance and credulity to get away with it.

In this example he uses a statistical theorem which will be obscure if not unknown to his audience, Baye's Theorem, and purports to show that it 'proves' the resurrection of Jesus was hugely more likely than unlikely.

Unfortunately, as Dr Freed, who understands this stuff, shows, his method actually showed that the resurrection could also be shown to be almost impossible using precisely the same technique, and how Lane Craig either deliberately, or through incompetence, made a schoolboy error. No one in the audience appeared to notice the sleight of hand, or, if they did, they didn't have the courage to speak out.

Watch it now, and I'll discuss it more in a few minutes to see what conclusions we can draw about William Lane Craig and religious apologetics in general.

Okay?

Hallelujah! Er... or not.
So, by the simple trick of concentrating on just one variable in the equation, Lane Craig seems, to the uneducated, to show that the probability of the resurrection of Jesus actually happening approaches 1 (certainty).

However, his reason for choosing this variable seems to be because it gives the answer he wants, or at least the answer he wants his audience to believe. Had he included the other variable, as he should have done, he would have shown that the probability of the resurrection of Jesus being true approaches zero (impossible).

In fact, of course, you can play exactly the same trick with any mythical event and 'prove' it is hugely likely to have really happened, especially if your audience is credulous and eager to believe it.

So, what can we conclude here?

William Lane Craig has implicitly presented himself as an expert in maths and as someone who understands Bayes' Theorem, and his audience is suitably impressed with this. Here is a 'brilliant thinker, Christian apologist and mathematician' using maths to prove Jesus almost certainly rose from the dead, just as the Bible claims.

So, there are two possibilities here, neither of which are to Lane Craig's credit:
  1. He is as clever as his audience has been lead to believe, and he is deliberately misleading them.
  2. He is misleading the audience about his cleverness in order to fool them.
It is unrealistic to assume that William Lane Craig does not know his audience well, and knows what he can and can't get away with so we can be sure that either one or other of these deceptions was deliberate.

It actually matters not which. The effect was the same: to trick his audience into thinking they had just watched a very clever argument by one of the leading Christian apologists which proved that the resurrection of Jesus was almost certainly true. In fact, all they had witnessed was a trick worthy of any conjurer, snake-oil pedlar, or confidence trickster. Lane Craig knew well enough that the wool between their ears could be pulled down over their eyes, and he knew exactly how to do it.

There is one more thing that this tells us about William Lane Craig and his commitment to truth, honesty and integrity. He claimed, apparently in all seriousness, that Bayes' Theorem, as he presented it, was a compelling argument that Jesus had indeed risen from the dead just as the Bible says. Certainly his audience were convinced by it and he did nothing to disavow them them of that belief.

Why then, now the mathematical error has been pointed out, and Bayes' Theorem has shown, by Lane Craig's own method but without the school-boy error, that Jesus almost certainly didn't rise from the dead, is this suddenly not the evidence it once was? Why is William Lane Craig not touring the country showing how Bayes' Theorem refutes the Christian Bible and the central Christian dogma? He wouldn't be selecting his data would he?

Is this a seeker after truth at work, or a seeker after book sales, speaking engagement fees and TV appearance money?

No prizes for the best answer.

What of the audience?

Well, we know that none of them pointed out Lane Craig's error so either they lacked the maths to spot it or lacked the courage to speak out. One of the tricks religious apologists employ is the 'Emperor's New Clothes' trick. This depends on people either not speaking out because they either don't have the courage to go against the crowd - probably through fear of what the crowd might do to them - or because they persuade themselves that maybe it's they who have the problem; that they saw the mistake or deception but think they are mistaken because no one else has seen it, so they keep quiet rather than look silly.

In effect, it's a form of passive-aggressive mob bullying or peer pressure. One wonders how many people come out of a William Lane Craig lecture wondering to themselves why they couldn't follow the intricacies of his reasoning but agreeing with everyone else how brilliant had been his argument, how unarguable had been his conclusions, and how right they are to hold the 'faith' they've just had so brilliantly 'proved' true.

This is a very powerful trick to use on an audience and accounts, at least in part, for so many charlatans getting away with it so often. It's the same trick as is used by preachers and priests on their congregation and by dishonest politician on their voters.

Religious apologists almost invariably talk to audiences composed largely of people who agree with them already and who are there simply to enjoy a celebrity apologist 'confirming' what they already know and to share in that nice warm, self-affirming glow of a shared experience and sense of being part of the in-group. In other words, the audience is already receptive and keen to agree with the speaker. The last thing they are looking for is dishonesty and sleight of hand. Apologists almost invariably speak to credulous audiences eager to agree and have any little doubts dispelled. It's what they are buying and the apologist knows well what he's selling.

The Fundomatic God Prover™

Fundamentalists seem to have been having a bad time recently as more and more people laugh at their arguments and counter them with reason, facts and logic.

I've always thought it a little unfair that fundamentalists, and especially Creationists have to cope with not having any evidence to support their claims, as though having to put up with an inability to think rationally and being inhibited by theophobia from thinking critically were not handicap enough.

So, to redress this imbalance, I bring you the Fundomatic Deity Prover©. Works for any god, even new ones.

Just pick any line at random to begin proving your favourite deity is real, then either follow the cross-references to join the others into a longer sentence by putting 'because' between them or wait till your opponent asks you for evidence for that assertion and use the next one to answer it. Don't forget to fill in the name of the god and your holy book correctly or you could be proving the wrong god. Remember to keep track of your position otherwise your proof might start to look like it's not joined up. When it starts to go round in circles tell your opponent that he/she keeps asking the same questions and break off the debate claiming victory. The best arguments are circular ones anyway because they keep proving themselves right and you don't need any real evidence.

After you've provided three or four of these proofs your opponent will probably realise he/she is not going to get very far with you and you will have won! Remember to always have the last word because that's what really counts.

What could be easier?

Any fundamentalist who thinks their best killer argument has been left out can add it to the comment section below. If they are new I'll adjust the F.D.P. to include them. Remember, they don't have to be provable.

Shifting The Burden

You see, if, in all seriousness, I claimed I have an undetectable hippo in my loft, challenged you to prove it didn't exist, and then claimed it must exist because you can't prove it doesn't, you'd probably think I was off my trolley and had lost my marbles.

Unless you're a religious fundamentalist that is.

If you are, you'd immediately recognise this argument as identical to the one you very probably use when confronted by Atheists. Almost invariably, you'll insist your god exists and challenge them to prove it doesn't, then claim it must exist if it can't be disproved.

If you're an honest religious fundamentalist, that is.

If you're a dishonest one you'll deny your argument is identical in logic to my silly hippo-in-my-loft argument and then try to bring in other arguments, change the subject and avoid dealing with the logical fallacy you've been caught trying to get away with.

Actually, it's not so much a logical fallacy as a dishonest tactic designed to overcome the fact that the perpetrator believe in something for which they have no supporting evidence. It betrays the fact that they know they have as much evidence for their god as they have for fairies, or I for my undetectable loft-hippo.

It's called shifting the burden. It's the tactic of making a claim you know you can't substantiate and then trying to divest yourself of the moral obligation to substantiate it. It's no different morally to going into court and claiming the accused is guilty, then challenging them to prove their innocence because you know you have no evidence. Another name for this tactic is 'bearing false witness'. It's implicitly claiming you have evidence for something for which you know you have no evidence.

Some examples of fundamentalists bearing false witness can be seen here:

For example, 18.How do we know the supernatural does not exist? The answer of course is that we don't. Dr Saunders is implicitly claiming it does and divesting himself of the responsibility of substantiating his claim, almost certainly because he knows he can't.


Here's the great Mat Dillahunty dealing with someone who's trying it on him:

To be fair to many fundamentalists, they probably don't realise they're being intellectually dishonest. They're probably just aping the tactics of the charlatan who fooled them with it in the first place and lack the intellectual integrity or ability to analyse the tactic and see it for the trick it really is.

You can see these unfortunate people almost daily rushing onto Twitter, Facebook, or other social media eager to try out their new killer argument having seen one of their heroes use it.

Hopefully, this article will help them see where they've been fooled and maybe come to terms with the fact that this is probably their best 'argument' for their god's existence and it simply serves to highlight the fact that they don't have one.

So, here's my top tip for fundamentalists who may be tempted to try this shifting the burden trick. If you can think of a logical reason why my claim to have an undetectable hippo in my loft isn't proven just because you can't disprove it, neither is your claim proven by me failing to disprove it. Your claim to have a god is only proven by you producing definitive, authenticated and indisputable evidence for it. Just because that is impossible for you does not excuse trying to fool people with a dishonest tactic and false witnessing.

If you ever feel tempted to try the shifting burden trick because you've been caught making a claim you can't justify, try changing the word 'god' or 'life after death' or 'sin' or 'soul' or whatever daft idea you're trying to get away with, for 'undetectable hippo in Rosa's loft' and see if it convinces you. If it doesn't, your trick won't fool normal people. It might fool another fundamentalist but that's kinda cheating. The tactic will simply betray your moral bankruptcy and the fact that you know you are making a false claim. The only way to escape that charge is to believe in my undetectable hippo, fairies, all the gods other people do or have believed in, pink unicorns and any daft notion you or anyone else can dream up because no one can prove a negative, which is why the trick is so beloved of religious apologists who need to earn a living somehow.

Of course, this will render you incapable of living a normal existence without close adult supervision but that's the price you may have to accept to avoid the charge that you tried a deception and failed to get away with it.

Why Evolution Is Not Random.

One of the tricks Creationists like William Dembski use is to tell their victims that evolution would need a hugely unlikely sequence of random chance events to occur to produce any given evolved entity, like a cell, a metabolic process or an organism such as a human being. They then produce some simple maths to seemingly show that the probability of this parody arising by chance is virtually indistinguishable from zero by multiplying all these tiny fractions together to get even smaller ones, and claim this shows evolution is, for all practical purposes, impossible.

Of course, this ignores all the principles of the real

Creationist 'Logic'.

Australopithicus afarensis (artist's impression)
Browsing idly through the hilarious Creationist website, answeringingenesis.org (always worth a few minutes if you've nothing worthwhile to do) I came across this stunning example of doublethink creationist 'logic' entitled ‘Oldest’ Hominid Footprints Show No Evolution! by one Alexander R. Williams, concerning the 1978 discovery of human-like footprints in volcanic ash at Laetoli in Kenya.
In 1974[sic], famous fossil hunter Dr Mary Leakey and her team were reported to have uncovered the oldest set of manlike (hominid) footprints ever found, supposedly 3.5 million years old, at Laetoli in East Africa. Most experts agree that these fossils are among the oldest evidence (on their own time-scale) that we have of man and his immediate ancestors. The majority of man-like fossils are all regarded as being younger than these.

In 1987 Mary Leakey published a book on the Laetoli finds.1 At the back of this book, R. H. Tuttle reported a study he had made on the footprints.2 Under a heading ‘Evolutionary Implications’ Tuttle says,
‘Strictly on the basis of the morphology of the G prints [prints found at a site labelled ‘G’], their makers could be classified as Homo sp. because they are so similar to those of Homo sapiens, but their early date would probably deter many paleoanthropologists from accepting this assignment. I suspect that if the prints were undated, or if they had been given younger dates, most experts would probably accept them as having been made by Homo . . . .

‘If the prints were produced by a small species of Australopithecus (southern ape) then we must conclude that it had virtually human feet which . . . were used in a manner indistinguishable from those of slowly walking humans. . . . The feet that produced the G trails are in no discernible features transitional between the feet of apes . . . and those of Homo sapiens. They are like small barefoot Homo sapiens.’
Tuttle then goes on to speculate about when man's ape-like ancestors began to walk upright.

We could not wish for clearer evidence from an evolutionist that it is only his (and his colleagues’) evolutionary assumptions that force him to reach evolutionary conclusions.

There are many similarities between apes and man, but one of the most distinctive differences is the feet. Ape feet are like our hands, with an opposable big toe (like our thumb). Human feet are different from any in the animal world—no other has feet like ours.

So the Laetoli footprints are clearly telling us that man was walking around as he does today when he first appeared in the fossil record. There is no sign of evolution here!
So, there we have it. Obviously, the fact that the human foot and bipedalism had evolved in a possible human ancestor 3.5 million years ago proves that the earth is only 6000 years old and evolution never happened.

The late Alexander R. Williams was a botanist.

How can science compete with devastating logic of this calibre?

Questions Christians Struggle (Or Refuse) To Answer.

First, a brief recap by way of explanation/introduction:

A week ago today, Dr Peter Saunders, CEO, Christian Medical Fellowship, published a list of 20 questions which he claimed in Atheists struggle to answer.

I responded (20 Questions Atheists Have Answered) by showing how these questions had all been addressed and answered and challenged Dr Saunders to explain in what way the answers are unsatisfactory.

So far, the only response has been to complain that the answer to the first question does not answer the question (something which can only be sustained by re-stating the question in an all-too-familiar apologetics tactic of moving the goalposts). This is despite Dr Saunder's continued assurance that he would answer my blog 'soon'.

My reply included several supplementary questions intended to give Dr Saunders an opportunity to explain precisely how he thought his questions represent a problem for Atheists and how a failure to answer them would support the hypothesis that actions by the Christian god alone could provide satisfactory answers.

To simplify Dr Saunder's task, I present the main questions again here, modified in places only slightly. The context of the questions is given by Dr Saunder's original question, shown in red.

Of course, other Christian apologists are more than welcome to try answering the questions. Apologists for other gods may also like to tackle these questions, suitably modified, because in almost every respect, these questions are used by supporters of other gods and other religions to justify their particular superstition, so, if you are a Muslim, simply change 'Christian god' for 'Islamic god', and so on.

1.What caused the universe to exist?

1.1. In the absence of a scientific answer to this question, how exactly do you conclude that the only alternative is that the Christian god caused the universe to exist?

2.What explains the fine tuning of the universe?

2.1. Why is there no possible natural explanation for the 'fine tuned' parameters to which you alludes?

3.Why is the universe rational?

3.1. Would you expect the universe to be irrational? If so, why?

4.How did DNA and amino acids arise?

4.1. If the answer to this question was truly unknown, in what way does it support the hypothesis that the Christian god is the only way to explain it?

5.Where did the genetic code come from?

5.1. Why would you expect the genetic code to not exist?

5.2. How would an inability of science to answer this question with complete certainty at present support the hypothesis that the Christian god is the only possible cause of the genetic code?

5.3. What medical advances can you think of which were produced by scientists looking at an unanswered question and concluding the a god must have done it?

6.How do irreducibly complex enzyme chains evolve?

6.1. How do you account for variations of these processes and of less complex chains producing the same or similar outputs in other species if the chains are really irreducibly complex?

6.2. Why would an intelligent designer design so many different ways to achieve the same result and why would it create analogous systems in species which, when arranged in order of degree of difference, look like they evolved from a common, more primitive ancestor?

6.3. How do you account for redundancy in organisms and evidence of inefficient, stupid design, such as the recurrent pharyngeal nerve and a broken ascorbic acid manufacturing process in many primates?

7.How do we account for the origin of 116 distinct language families?

7.1. If this had been unknown to science, in what way precisely does it undermine the Atheist position that there is no evidential reason to believe in any god?

8.Why did cities suddenly appear all over the world between 3,000 and 1,000BC?

8.1. How do you account for the continued existence of subsistence agriculture, hunter-gatherer peoples and nomadic pastoralism if, as you claim, there were cities all over the world?

8.2. How does the existence of cities support the notion of the existence of the Christian god?

8.3. If cities were somehow facilitated by your favourite god, why did it wait until 3000 years ago and take 2000 years to spread the idea, and why did it not give them to everyone?

9.How is independent thought possible in a world ruled by chance and necessity?

9.1. Why would you expect it not to be?

9.2. Why do you believe thought is independent? Independent of what, exactly?

9.3. Why do you believe the world must be 'ruled by chance and necessity' if it's not ruled by the Christian god?

9.4. In what way is this question a problem for the Atheist position that there is no evidential reason to believe in any gods?

10.How do we account for self-awareness?

10.1. If science had been unable to offer an explanation of self-awareness, how would that gap undermine the Atheist position that there is no evidential reason to not be an Atheist?

10.2. How do you account for very evident self-awareness in other species?

11.How is free will possible in a material universe?

11.1. Why would you expect a material universe to have any impact on that debate and why, as your question implies, would you expect it to render it impossible?

11.2. How can free will exist in the presence of an eternal, omniscient and inerrant god?

11.3. How does the existence or otherwise of free will impinge upon the Atheist view that there is no evidential reason to believe in a god?

12.How do we account for conscience?

12.1. Why would you expect an evolving, intelligent, social ape not to evolve a set of memes by which to work together as a co-operative society?

12.2. How do you distinguish between someone who doesn't know right from wrong and needs to look them up in a book and a psychopath?

12.3. How do you account for the differences between different human cultures and societies if they all get their moral codes from the same supernatural source?

12.4. How do you account for the fact that a society like Sweden with it high Atheist population is more peaceful and has far less crime than a highly religious, predominantly Christian society, like the USA?

12.5. How do you account for the statistics in this blog - Not Good With God?

12.6. If you believe you can only tell right from wrong by reference to the Christian Bible, how do you know it was written by a moral god and not an evil one trying to mislead you? In other words, how do you know Satan didn't write the Bible?

13.On what basis can we make moral judgements?

This is, of course a repeat of question 12 so I won't bother to restate the same questions just to make up the numbers.

14.Why does suffering matter?

14.1. Why does suffering not matter to so many species in a universe you believe to have been created by a caring and compassionate god?

14.2. Why does pain persist when it has ceased to fill any useful survival purpose?

14.3. Why would you expect an evolving, intelligent, social ape to not be compassionate and care about its fellows when this produces a better, more co-operative, and more trusting society.

14.4. Why has Christianity so frequently and readily used deliberately brutal methods of torture and execution for those with whom it disagrees, as shown here and here?

15.Why do human beings matter?

15.1. Why do humans not matter to non-humans if, as you believe, the universe was created for them by a caring and compassionate god?

15.2. Why does it look as though morality evolved in humans by a process of memetic evolution similar to the process of genetic evolution?

15.3. How do you account for parasites like these in a universe created by a caring and compassionate god?

15.4. If there is a caring and compassionate creator god why does it look as though he hates Africans, and especially the children?

15.5. How can this photograph exist in the presence of a caring and compassionate god?

16.Why care about justice?

16.1. What precisely do you find inadequate about the answers meme theory provides?

16.2. How would failure to explain human cultural evolution as a natural process undermine the atheist idea that there is no evidential reason to believe in any god?

17.How do we account for the almost universal belief in the supernatural?

17.1. How do you account for a falling belief in supernatural explanations as science makes more and more discoveries, and by a lower levels of belief in the supernatural by the more scientifically literate?

17.2. Why did the supply of prophets and miracles appear to reduce markedly as we became more and more knowledgeable and our understanding of the universe increased?

17.3. Why is 'magic' a more satisfactory answer to mysteries than saying "we don't yet know but we're working on it"?

18.How do we know the supernatural does not exist?

18.1. I normally take an attempt to divest oneself of the burden of proof as evidence of an awareness that the idea being presented is false and of the intellectual dishonesty and moral ambivalence of the perpetrator. Why should I not do so in this case?

18.2. If your god is supernatural, so by definition cannot interact with the natural universe, how does it influence anything?

18.3. If it can influence anything it is not supernatural so should be detectable by science. Has your god been so detected? if so, where may the evidence be seen?

19.How can we know if there is conscious existence after death?

19.1. If your belief is that there is conscious existence after clinical death the burden of proof lies with you. Do you have any evidence for it's continuation?

20.What accounts for the empty tomb, resurrection appearances and growth of the church?

20.1. Again there is the attempt to shift the burden which has started to become almost a signature technique and which raises serious questions of sincerity in my mind. Do you have any extra-biblical evidence that there was an 'empty tomb' resulting from a resurrection?

20.2. How do you account for the four markedly, and often contradictory, accounts for them in the Christian Bible?

20.3. Given the statement purportedly by Jesus, that he would build his (singular) church on the rock of Simon "Peter" Barjonah, and his alleged prophecy that the gates of Hell would not prevail against it, How do you account for the 38,000 or so Christian sects, many of whom regard the others as Satanic creations?

20.4. Do you not feel embarrassed at needing to use this intellectually dishonest tactic of the false dichotomy, which is no more an argument for your god than it is for any other and which relies entirely on the parochial ignorance of its targets to work?

20.5. Why have you not presented a single scrap of evidence for your preferred god and explained why it can only be used in support of your particular god? Do you not have any?

Evolution Gave Us This Day Our Daily Bread

An interesting recent occurrence of speciation gave rise to bread wheat, i.e. the variety of wheat (Triticum aestivum) used to make the flour we in the west use to make bread. It was not a straightforward event and needed an earlier speciation events to occur in the wheat family to produce the two parent plants which hybridised to make our daily bread.

This is a good example of speciation due to a change in the number of chromosomes to produce a condition known by biologists as polyploidy. A brief explanation of polyploidy follows for those non-biologists who may be reading this blog, so skip the next three or four paragraph if you know this already.

Each species has a basic number of chromosomes in its cells. in most normal adult forms each chromosome is paired so that we have two of each. So the base number is 2n where n is number of pairs. 'n' is known at the haploid number so normal adult cells are diploid (i.e. 2n).

The cells from which most individuals are made at fertilization are haploid. These are produced in the germ cells when the reproductive cells or gametes are produced by a special form of cell division in which one of each pair of chromosomes goes to each pair of cells produced instead of the chromosomes doubling first as in normal cell division. This is called meiosis.

In the case of mammals, meiosis produces sperm in males and ova or eggs in females. In the case of flowering plants it produces pollen (male) and the ovules (female) reproductive cells. When these gametes fuse together they create a diploid cell which develops into the normal individual.

Ploidy then refers to the number of chromosomes in relation to this normal haploid number. In normal humans we have 23 pairs of chromosomes (including the x and y chromosomes which determine gender but which are not really pairs as such in males, who have one of each)

Particularly in plants, polyploidy, i.e. where the normal individual had a multiple of the haploid number, often, but not always, tetraploid (4n) is fairly common and is a frequent cause of speciation. This occurs when there is a fault with meiosis and one gamete gets both pairs of chromosomes. If this happens in a pollen grain and in an ovule which happen to come together in fertilization, the resulting cell can be viable. The production of diploid gametes if probably fairly common but what is rare is for them to find another diploid gamete to fuse with, and for that to produce a viable seed.

When this happens between two related species is it known as allopolyploidy and the resulting hybrid is said to be amphidiploid (i.e double diploid) or tetraploid.

Anyway, from an examination of the genome of bread wheat, it is now clear that, not only did it result from just such an allopolyploid hybrid speciation event but that one of the parent species which hybridized was itself produced in an earlier allopolyploid hybridization. The result of this is that bread wheat is hexaploid (i.e. 6n) rather than the normal 2n or less frequent 4n arrangement.

At some time in the past the cultivated form of Triticum monococcum allopolyploidily (not a word to say after a couple of G & T's) hybridized with T.saersii to produce the wild T.turgidum. T.monococcum had been cultivated as Einkorn wheat. Then about 10,000 years ago, wild T.turgidum began to be cultivated as Emmer wheat. This in turn then hybridized with another wild wheat, T.tauschii, to produce T.aestivum which has been cultivated for about 8,000 years.

And, of course, not having a chromosome number which will normally successfully pair up with any other species of wheat other than itself in reproduction, including the parent species, bread wheat is genetically a fully isolated species in it's own right, filling all the criteria of a distinct species.

So, there are a couple of serious problems here for Creationists, the major one being why an intelligent designer would cause different species to hybridize in such a way as to produce a huge number of chromosomes, with all the in-built redundancy that entails, and spread this over several thousand years, when a single act of creation could have achieved the same result with only the normal number of chromosomes and far less, if any, genetic redundancy.

Creationists also need to explain why it looks like human agency was involved if only by producing a large number of cultivated plants in a small area which would have facilitated this hybridization and made it much more likely than mere chance, and of course by producing the highly favourable selective environment which ensured reproductive success of the hybrids.

Those Creationists who insist that speciation cannot occur by a natural process, especially by an evolutionary one, and that magic done by a special magician must be involved to produce new species, have to explain why the process described above is impossible and why magic must have been involved.

And of course, as with all creationist explanations, there is always the essential ingredient of magic to be explained away, along with the origin and nature of the magician and how exactly it works, so their explanation is infinitely complex and hopelessly incomplete and inadequate.

For evolutionary theorists, of course, there is no mystery to be solved; there is no magic to be explained and no infinite complexity. The explanation is entirely complete and includes nothing which is included merely to satisfy the superstition of the proposer. It's all due to a fully understandable natural process. As always, the best explanation is the least complex and most vicarious one, as William of Occam showed. His trusty razor once again pairs gods and magic out of the explanation and produces a fully worked-out theory which explains the evolution of bread wheat.

One really has to pity the poor Creationists as they struggle to fit observable reality into a primitive superstition so singularly ill-fitted for purpose.

More details of this process can be read on the National Center for Biotechnology Information website in the article entitled Changes in Chromosome Number from the book, Modern Genetic Analysis by Griffiths AJF, Gelbart WM, Miller JH, et al. New York: W. H. Freeman; 1999.

How Creationists Lie to Us - 15

Readers of my blog will be aware that I have recently been in 'debate' with Dr Peter Saunders, CEO Christian Medical Fellowship over his claim in his blog, 20 Questions atheists struggle to answer, that there are 20 questions which "as yet in over forty years of discussion with [Atheists] I am yet to hear any good [answers]".

In the blog, 20 Questions Atheists Have Answered, I showed that all these questions have been answered, either by answering them using established science, or provided links to books and articles which answer the questions asked.

I have since been waiting for Dr Saunders to respond, specifically to explain why he believed these questions had not been answered when they clearly have been. So far he has failed to do so, though he is now using Twitter to tweet a link to a Christian apologetics website which purports to (Questions That One Atheist Could Not Answer). The article on this site is anonymous and there is no opportunity to reply to it. I have asked Dr Saunders if this represents his view and should be taken as his definitive reply. He has not provided any reference to it either in reply to my comments on his original blog nor on my blog.

However, the article is interesting in its own right, not for it's reply per se but for what it reveals about the technique of Christian apologetics and how this is used to deceive and mislead rather than to inform through honest debate and to arrive at the truth through reason. This is illustrated very nicely by the 'reply' to the very first reply.
While I am certain that if I dug into her responses to the other questions, I would find much intellectual inadequacy (based on the responses that I found here), but I will leave them for somebody else to dissect. I offer a response to seven bad objections.

Question One: What Is The Cause Of The Universe?

Rosa’s Response:
We do not know exactly what happened in the first 1*10-43 [note that I expressed this throughout as 1*10-43] seconds of the life of the universe. This is the Planck length of time, in other words, the smallest unit of time which can exists so it is, in effect, unexaminable by science. Stephen Hawkings, in The Grand Design goes into this question at some length and concludes unequivocally that gravity alone is sufficient to explain it and that there is no evidence for a supernatural involvement.

Given that, at the quantum level, there is no such thing as nothing and everything is subject to unbounded fluctuation, this initial Planck length of time probably does not need to be explained in terms other than an unbounded quantum fluctuation. At the moment of it’s nascences, the universe was already 10-43 seconds old and this time is sufficient for gravity to separate from the other three forms of energy, so allowing a hyperinflation in which energy can be created with reduced entropy so obeying the Laws of Thermodynamics. Science has developed very accurate mathematical models of the Big Bang following this initial 10-43 seconds and observation has confirmed these models to a remarkably high degree of accuracy.
This is a very strange response, for it does not attempt to answer the question at all. The question is, “What is the cause of the universe?” But instead of tackling that question, Rosa answers, “what is the material cause of the formation of the universe?”
So the question is now miraculously re-defined. Having tapped the ball into the empty goal-mouth the goal-posts are relocated to a different part of the pitch. The 'cause' of the universe as originally referred to now does not include the 'material' cause, but something else. And of course, that 'immaterial' cause can only be the Christian god since that is the only one which the author will accept. How to dismiss an answer and hope the credulity of your readers will prevent them noticing the intellectual dishonesty.
Rosa answered a question that was not posed. But to the question that was posed, she replied that she does not know.
So, from "it does not attempt to answer the question at all" the complaint is now that I replied that we do not know the precise details of something which is probably fully explained as a quantum fluctuation anyway... (Note how my reply was truncated to remove the pertinent part in an astonishingly blatant display of selective quote-mining worthy of any creationist 'science' website).

There then follows a puff for an article by our anonymous author and a rather sad repetition of the long-refuted Kalam Cosmological Argument about which many books and articles have been written, including my own, Favourite Fallacies - The Kalâm Cosmological Argument. The KCA is of course nothing more than the God of the Gaps and the Argument From Ignorance fallacies dressed up to look intellectual and which, with equal (in)validity can be used to support any god or any other daft notion one can invent to explain something unknown. Indeed, it was originally devised by Islamic scholars to promote Allah, which few, if any Christians would try to present as the one true god as revealed to Mohammed...

[...]
So Rosa’s objection to the claim that atheists’ struggle to answer this question is not founded on any intellectual basis (at least not in this writing).
Er... apart from showing exactly how the question could be and had been answered and providing links to sources which did exactly that, and thus falsifying the claim...
However at the end of the writing, she offers three questions meant for Doctor Saunders. I will be so bold as to answer in his absence.
Were you unaware of the work of Hawkins, Krauss, and Stenger?
No.
Then you were aware that the question had been answered by Atheists and your pretence that is has not been is dishonest and disingenuous, as is your pretence that I was addressing something other than a claim that this question had not been answered.
If not unaware, in what way are their explanations unsatisfactory?
They attempt explain the material cause of the universe (the stuff out of which the universe is made) but not the efficient cause of the universe (the cause that brought the universe into being).
In other words, they don't answer a different question to the one asked and for which the only answer you will accept is that the Christian god did it. Sorry, but there is no requirement for science to include your magic friend in any explanation to make it's answers satisfactory. If you insist on complaining that science doesn't agree with your superstition you merely betray the fact that your superstition is wrong.
In the absence of a scientific answer to this question, how exactly do you conclude that the only alternative is that the Christian god caused the universe to exist?
It is not that a scientific answer is absent; it is a matter of deduction.
Which of course neatly side-steps the question and the fact that the argument relies entirely on presentation of a dishonest false dichotomy in what is clearly a well-rehearsed attempt to divert the question. Even if there is a gap in scientific knowledge, it does not follow that the Christian god is the only possible alternative answer on offer. I have previously shown how this dishonest tactic depends entirely on the parochial ignorance of its target in The False Dichotomy Fallacy - Creationism's Moral Failing. The anonymous author's response to this question betrays his awareness that it destroys his entire tactic.
From the argument that I presented, we are justified in deducing the existence of a timeless, spaceless, immaterial, powerful, intelligent, personal Creator of the universe. However this argument does not aim to demonstrate that the Christian God exists; just that God exists.
Except, of course, as you know, you have presented nothing more than a god of the gaps argument, an argument from ignorance and a false dichotomy, in lieu of a single shred of anything resembling evidence for the Christian god, let alone explaining how, in the absence of a scientific answer, this god should be regarded as the only alternative explanation on offer.

So there we see:
  1. A claim that a question has never been answered refuted by evidence which is simply waved aside.
  2. An attempt to redefine the question to avoid the fact that the one asked has been answered.
  3. A false claim that the question has not been answered followed by a complaint that the answer was not the one wanted.
  4. The presentation of a dishonest false dichotomy and a clearly rehearsed response to this charge which betrays the dishonesty of the tactic being employed and the author's awareness of it.
All good examples of how Creationists try to get away with tactics over substance and aim their arguments at the credulous and gullible, and of their intellectual dishonesty and their need to use the tactic of the confidence trickster and the snake-oil salesman.

The Houla Massacre And Faith-Based Initiatives.

BBC News - Houla eyewitness: 'They had no mercy'

And so the world witnesses another brutal massacre of women and children by people who've come to see themselves as superior to others and so have assumed for themselves the power of life and death over others.

But is this really surprising in a part of the world still dominated by a religious superstition having it's origins in the brutal pre-civilised Bronze Age when massacres of the sort were routine and are still defended as right and proper by people like William Lane Craig and other politically motivated pseudo-religious apologists?

In fact, it's professional theologians who dutifully trot our whatever justification their 'cause' requires of them who encourage, facilitate and permit these indefensible acts of inhuman barbarity. Alex Alvarez in Justifying Genocide: The Role of Professionals in Legitimizing Mass Killing explains how this happens.

It's perhaps worth recalling how leading Christian apologist William Lane Craig defended the Canaanite Genocide described triumphantly in the Christian Bible:
But why take the lives of innocent children? ... if we believe, as I do, that God’s grace is extended to those who die in infancy or as small children, the death of these children was actually their salvation. We are so wedded to an earthly, naturalistic perspective that we forget that those who die are happy to quit this earth for heaven’s incomparable joy. Therefore, God does these children no wrong in taking their lives.

So whom does God wrong in commanding the destruction of the Canaanites? Not the Canaanite adults, for they were corrupt and deserving of judgement. Not the children, for they inherit eternal life. So who is wronged? Ironically, I think the most difficult part of this whole debate is the apparent wrong done to the Israeli soldiers themselves. Can you imagine what it would be like to have to break into some house and kill a terrified woman and her children? The brutalizing effect on these Israeli soldiers is disturbing.

William Lane Craig, professional Christian apologist
Killing children is good for them. It makes them happy and we should actually pity the "traumatized" soldiers who have to break into houses and murder them! He actually said that!

No. I couldn't believe it either until I saw Lane Craig saying it for myself here:

"It's not a pleasant job, but somebody has to do it. It's all to the good in the end!"

I wonder how many guards at Treblinka, Dachau, Belsen, Buchenwald and Sobibor said that.

William Lane Craig is highly regarded as a theologian in American right-wing circles and even has a band of loyal devotees in other English-speaking countries.

So, if you want to see what America would be like if Craig and those to whom he provides his repugnant apologetics ever gained the power they seek, look no further than the Syrian village of Taldou near Houla where at least 108 people, including women and children, were dragged from their homes and massacred in something remarkably similar, though on a smaller scale, to the Canaanite Massacre some 3500 years earlier and a little way to the south, by people who believed they had a duty to do it because their priests and authority figures told them they had.

I wonder if those who carried out the crime think they should be pitied for being traumatized in the process of doing their essential work and clearing the world of lesser beings and undesirables. There can be little doubt that William Lane Craig would regard our instinctive human revulsion over these 'faith-based initiatives' as an "emotional outburst" indicative of a character flaw and a lack of intellect, as he chillingly explained here in a reply to one of his devoted right-wing loon followers.

20 Questions Atheists Have Answered


This blog is in reply to a blog entitled Twenty questions atheists struggle to answer by Dr Peter Saunders, CEO Christian Medical Fellowship. Dr Saunders claims in his blog:

I am not, in posting these, saying that atheists have no answers to them, only that as yet in over forty years of discussion with them I am yet to hear any good ones

Of course, neither I nor Dr Saunders is the final arbiter of whether an argument is good or not, so presumably we should interpret that claim as that he has not accepted these answers. He has an opportunity to explain why not here, rather than merely waving them away as 'not good'.

I have addressed these answers personally to Dr Saunders but please feel free to answer them if you think Dr Saunders is right, or that the answers are unsatisfactory.

More Good Christian Love

Pope Clement V, the first Avignon Pope
In a previous blog on the brutal suppression of the Cathars of southern France I showed an example of the huge gap between what the Christian Church tells us to do and what it does itself. One might expect a Church which teaches love, compassion, ascetic poverty, giving to the poor and the sanctity of life, and which claims to be based on sound philosophical reasoning and the teachings of 'perfect' Jesus, to show these qualities itself when discussing differences of opinion amongst its followers.

But not a bit of it. Throughout history, the normal response has been a resort to armed power, to brutal suppression, grotesque methods of mass destruction and rigidly enforced dogma from a position of obscene wealth and splendour. Maintenance of this wealth and power seems to have been the primary motive for the Church, rather than spreading the 'Love of Jesus' and the elevation of all of humanity above the level of the humble peasant and toiler for the landed gentry which was the lot for the vast majority of medieval Europeans whose poverty and labour were the source of the Church's and the small powerful ruling elite's wealth.

The Christian religion was clearly the means to an end rather than an end in itself and it could be moulded and bent into whatever shape suited the rich and powerful at the time.

Proof Of Noah's Flood!

Christian archaeologists have found astonishing evidence of the Biblical flood, it was revealed today. Excavations in the Forbidden City in Beijing have uncovered a message sent to to the First Emperor, Qin Shi Huang

This translates as:

To Emperor Qin Shi Huang.
Very sorry. No work on Great Wall. No one alive in world. All drown in flood of Christian Bible.

Humble slave,

Sammy Chan, Foreman, East is Red Construction Team.
2500 BC.

It has been acclaimed as a Message From God! Christian apologist David Barton welcomed the find but explained that it was nothing new. "We have dozens of these messages from all over the world. They turn up regularly and are even quoted verbatim in the Declaration of Independence and in the US Constitution", he said.

C.S.Lewis Dispenses With Faith

Here is C.S.Lewis on 'Faith', again from his 1952 book "Mere Christianity". It illustrates well the conceited vacuosity of his religious views and how his frankly annoying patronising style almost seems designed to gloss over it and to rely on the deferential social mores of his target audience. It oozes with 'niceness' and smugly reassuring self-satisfaction but actually says very little other than "believe what I say". I'm sorry it's so long but he probably had space to fill.
I must talk in this chapter about what the Christians call Faith. Roughly speaking, the word Faith seems to be used by Christians in two senses or on two levels, and I will take them in turn. In the first sense it means simply Belief-accepting or regarding as true the doctrines of Christianity. That is fairly simple. But what does puzzle people-at least it used to puzzle me-is the fact that Christians regard faith in this sense as a virtue, I used to ask how on earth it can be a virtue-what is there moral or immoral about believing or not believing a set of statements? Obviously, I used to say, a sane man accepts or rejects any statement, not because he wants or does not want to, but because the evidence seems to him good or bad. If he were mistaken about the goodness or badness of the evidence that would not mean he was a bad man, but only that he was not very clever. And if he thought the evidence bad but tried to force himself to believe in spite of it, that would be merely stupid.

Well, I think I still take that view. But what I did not see then- and a good many people do not see still-was this. I was assuming that if the human mind once accepts a thing as true it will automatically go on regarding it as true, until some real reason for reconsidering it turns up. In fact, I was assuming that the human mind is completely ruled by reason. But that is not so. For example, my reason is perfectly convinced by good evidence that anaesthetics do not smother me and that properly trained surgeons do not start operating until I am unconscious. But that does not alter the fact that when they have me down on the table and clap their horrible mask over my face, a mere childish panic begins inside me. I start thinking I am going to choke, and I am afraid they will start cutting me up before I am properly under. In other words, I lose my faith in anaesthetics. It is not reason that is taking away my faith: on the contrary, my faith is based on reason. It is my imagination and emotions. The battle is between faith and reason on one side and emotion and imagination on the other.

When you think of it you will see lots of instances of this. A man knows, on perfectly good evidence, that a pretty girl of his acquaintance is a liar and cannot keep a secret and ought not to be trusted; but when he finds himself with her his mind loses its faith in that bit of knowledge and he starts thinking, "Perhaps she'll be different this time," and once more makes a fool of himself and tells her something he ought not to have told her. His senses and emotions have destroyed his faith in what he really knows to be true. Or take a boy learning to swim. His reason knows perfectly well that an unsupported human body will not necessarily sink in water: he has seen dozens of people float and swim. But the whole question is whether he will be able to go on believing this when the instructor takes away his hand and leaves him unsupported in the water-or whether he will suddenly cease to believe it and get in a fright and go down.

Now just the same thing happens about Christianity. I am not asking anyone to accept Christianity if his best reasoning tells him that the weight of the evidence is against it. That is not the point at which Faith comes in. But supposing a man's reason once decides that the weight of the evidence is for it. I can tell that man what is going to happen to him in the next few weeks. There will come a moment when there is bad news, or he is in trouble, or is living among a lot of other people who do not believe it, and all at once his emotions will rise up and carry out a sort of blitz on his belief. Or else there will come a moment when he wants a woman, or wants to tell a lie, or feels very pleased with himself, or sees a chance of making a little money in some way that is not perfectly fair: some moment, in fact, at which it would be very convenient if Christianity were not true. And once again his wishes and desires will carry out a blitz. I am not talking of moments at which any real new reasons against Christianity turn up. Those have to be faced and that is a different matter. I am talking about moments where a mere mood rises up against it.

Now Faith, in the sense in which I am here using the word, is the art of holding on to things your reason has once accepted, in spite of your changing moods. For moods will change, whatever view your reason takes. I know that by experience. Now that I am a Christian I do have moods in which the whole thing looks very improbable: but when I was an atheist I had moods in which Christianity looked terribly probable. This rebellion of your moods against your real self is going to come anyway. That is why Faith is such a necessary virtue: unless you teach your moods "where they get off," you can never be either a sound Christian or even a sound atheist, but just a creature dithering to and fro, with its beliefs really dependent on the weather and the state of its digestion. Consequently one must train the habit of Faith.

Probably the key phrase in all this is, "But supposing a man's reason once decides that the weight of the evidence is for it".

Nowhere in this book does he say what evidence convinced him. All his reasons for being a Christian are based on negatives and absent evidence; because he can't explain something using his rather tenuous grasp of science, or doesn't understand something, he declares it inexplicable, fills the gap with a god and deems it to be the god his parents told him about. To Lewis, it seems 'unknown' and 'unknowable' are synonyms. And of course this god is to be worshipped according the the rites and rituals of the church his was baptised into as an infant. Never a shred of definitive evidence is ever offered for this god nor any explanation of why, if he has to invoke a god, it follows that it must be the god of the Christian Bible.

How could the English have possibly got the wrong god? The idea is not even worth considering.

Nope. There must be a god and it must be Lewis' god because there are things Lewis can't understand, and it is virtuous to just have faith in that conclusion. And faith means never having to change your mind even when the evidence changes or you realise the 'evidence' wasn't what you thought it was.

To borrow a metaphor from Richard Dawkins, there is not sufficient evidence to have a firm belief either way on the cause of the mass extinction of dinosaurs. There is evidence that it could have been a large meteorite strike. It is plausible that it could have been a virus. It could possibly have been a catastrophic climate change caused by a super volcano. It is sheer arrogance to merely opt for one of those and then proclaim it a virtue to cling to that belief even when the evidence changes. Not only arrogant but vain, something Lewis regards as a sin. It can only come from the belief that one can merely 'know' the truth; that somehow something must be true because one believes it.

Faith, in the absence of definitive evidence, is not a virtue; it is the sin of vain arrogance writ large.

The mere fact that C.S.Lewis has opted to believe in the Christian god is sufficient reason for him to believe in it. None of this nonsensical subservience to reality and dependence on evidence for our hero. He comes from a class which not even the universe would dare to question. Reality is what he says it is and that's an end to the matter. He would not believe it if it were not just so.

And of course any reasonable plebeian hearing truth and wisdom dispensed by a brilliant Oxford don who even writes children's books, should accept it as good enough for him and marvel at the benevolence of such a nice man dispensing his knowledge so nicely, and with such simple words too.

What a wonderful example of a nice Christian.

40 Killer Arguments For Internet Creationists.

So, you've decided to be a Creationist and convince people that science is wrong and your favourite god really created the universe in six days out of nothing, and made humans out of dust (or a lump of mud). I bet you're really fed up with scientists and Atheists having all the facts, evidence and logic on their side and with having to make do without any. I bet you really wish you could win just one debate without having to flounce of in righteous indignation, avoid answering questions, needing to resort to abuse and threats, or simply boring the pants off people by repeating questions and ignoring answers until they ignore you.

Don't worry. You can win! This is all you need to do.
  1. Have a list of questions you don't want answered. Check on any Creationist website for these.
  2. Keep asking these questions over and over but ignore the answers.
  3. Never be tempted to follow any links or read any books which might be recommended.
  4. Demand absolute proof for every scientific theory. Never accept it.
  5. Claim Creationism is proved because it's written about in a book and you believe it.
  6. Produce random quotes from a religious book and claim that proves it.
  7. Say that faith is better than evidence so it must be true otherwise you wouldn't believe it.
  8. Claim to have absolute proof that your god exists. Never produce it because it might be falsifiable.
  9. Promise that you will produce that proof soon but demand that it be accepted first.
  10. Refuse to produce the proof because it would be wasted on someone who won't accept it.
  11. Never say what you would accept as proof of Evolution or the Big Bang in case it's provided.
  12. Never say what you would accept as falsifying Creationism in case it's provided.
  13. Never say what testable predictions Creationism makes in case they are tested.
  14. Never say what the definitive evidence for Creationism is, in case people look for it.
  15. Never explain why your version of Creationism is better then any other.
  16. Never explain why, if science is wrong, Creationism should be the only alternative on offer.
  17. Claim absence of evidence for your god isn't evidence of absence so it must be proof of presence.
  18. Don't worry about using a computer to argue that science doesn't work.
  19. When pressed for an answer you don't have, claim you've answered it already.
  20. Claim the evidence for Creation is 'everywhere' but people won't look at it.
  21. Complain that no one has ever managed to answer any of your questions.
  22. Assert that Darwin believed in Intelligent Design.
  23. Claim that Darwin recanted on his death bed.
  24. Claim that Darwin was a Communist.
  25. Say that irreducible complexity proves life is intelligently designed. Avoid technical discussion.
  26. Assert that Evolution was falsified by science many years ago.
  27. Claim that the Second Law of Thermodynamics means Evolution is impossible. Avoid discussion.
  28. Assert that there is no evidence for Evolution.
  29. Say that Darwin admitted God must have designed eyes.
  30. State that the Peppered Moths experiment was a fraud.
  31. State that Coelacanths prove Evolution doesn't happen.
  32. Claim that all fossils are forgeries made of plaster of Paris.
  33. Assert that there are no transitional fossils.
  34. Assert that Evolution has never been seen.
  35. Don't take any notice of the detailed rebuttals you'll get.
  36. If needs be, resort to condescension, passive-aggressive threats like saying you'll pray for them, and abuse.
  37. It's okay to call scientists mad because they usually are from all that reading and learning they do - which is why you should avoid it.
  38. Never get into technical arguments with real scientists, especially biologists, because you know how they can prove anything they want with facts.
  39. Tell people they'll burn in Hell if they don't agree with you.
  40. When you've got through this list just start again. People might have forgotten you had all of your questions answered and arguments refuted.

So there you are. You can now go on line and hold your head high in Creationist circles, sure of their admiration at the depth of your knowledge and the brilliance of your debating skills.

Those crazy elitist scientists and Godless heathen Atheists won't stand a chance!

C.S.Lewis Gets It Wrong Again

More smugly self-satisfied moralising from C.S.Lewis' 1952 book, "Mere Christianity". This time it's quite easy to see why he got it wrong. It was a combination of ignorance and arrogance, of which, as so often with Lewis, arrogance was the main failure.
Some people say that though decent conduct does not mean what pays each particular person at a particular moment, still, it means what pays the human race as a whole; and that consequently there is no mystery about it. Human beings, after all, have some sense; they see that you cannot have real safety or happiness except in a society where every one plays fair, and it is because they see this that they try to behave decently. Now, of course, it is perfectly true that safety and happiness can only come from individuals, classes, and nations being honest and fair and kind to each other. It is one of the most important truths in the world. But as an explanation of why we feel as we do about Right and Wrong it just misses the point If we ask: "Why ought I to be unselfish?" and you reply "Because it is good for society," we may then ask, "Why should I care what's good for society except when it happens to pay me personally?" and then you will have to say, "Because you ought to be unselfish"-which simply brings us back to where we started. You are saying what is true, but you are not getting any further. If a man asked what was the point of playing football, it would not be much good saying "in order to score goals," for trying to score goals is the game itself, not the reason for the game, and you would really only be saying that football was football-which is true, but not worth saying. In the same way, if a man asks what is the point of behaving decently, it is no good replying, "in order to benefit society," for trying to benefit society, in other words being unselfish (for "society" after all only means "other people"), is one of the things decent behaviour consists in; all you are really saying is that decent behaviour is decent behaviour. You would have said just as much if you had stopped at the statement, "Men ought to be unselfish."

And that is where I do stop. Men ought to be unselfish, ought to be fair. Not that men are unselfish, nor that they like being unselfish, but that they ought to be. The Moral Law, or Law of Human Nature, is not simply a fact about human behaviour in the same way as the Law of Gravitation is, or may be, simply a fact about how heavy objects behave. On the other hand, it is not a mere fancy, for we cannot get rid of the idea, and most of the things we say and think about men would be reduced to nonsense if we did. And it is not simply a statement about how we should like men to behave for our own convenience; for the behaviour we call bad or unfair is not exactly the same as the behaviour we find inconvenient, and may even be the opposite. Consequently, this Rule of Right and Wrong, or Law of Human Nature, or whatever you call it, must somehow or other be a real thing- a thing that is really there, not made up by ourselves. And yet it is not a fact in the ordinary sense, in the same way as our actual behaviour is a fact. It begins to look as if we shall have to admit that there is more than one kind of reality; that, in this particular case, there is something above and beyond the ordinary facts of men's behaviour, and yet quite definitely real-a real law, which none of as(sic) made, but which we find pressing on us.

Writing in 1952 it is not surprising that Lewis was ignorant of memes and memetic evolution, so we can perhaps forgive him for that, but never-the-less we should expect him to have been aware of Occam's Razor and how it should be used to produce the most vicarious explanation. Instead, he waves aside any possible natural explanation in favour of one which requires magic and an unexplained mystery, but which serves his purpose if his reader can be relied on not to probe too deeply.

Australopithicus africanus (artists impression)
This puny ape was only ever going to succeed by cooperating.
Evolution of cultures, together with the rules which facilitate co-operative behaviour are fully understandable in terms of memetic evolution by an evolutionary process. Human groups which were more co-operative would have been more successful in the conditions in which we were evolving and co-operation depends on team skills, which themselves rely on mutual trust. In conditions where an increasingly intelligent brain was also evolving these memes would have developed and so in turn facilitated an even more rapidly evolving brain.

Hence meme-gene co-evolution would have facilitated both the development of a brain able to hold and use these memes and the memes themselves, producing more successful groups and cultures, leading eventually to the evolution of an intelligent ape which today we call Homo sapiens complete with a set of evolved cultural norms and ethics which we inherit from our parents, peers and authority figures in our society.

Whilst the basic principles of treating others with respect, doing least harm and the empathetic skill of judging what you would want done to or for you, if you were the other person, are more or less common to all human societies and groups, the details often differ considerably.

Queueing is one example. I remember being shocked when in former Yugoslavia in the 1970 I had waited with some friends for a bus. We had arrived early and took up our position at the bus-stop sign, as we would have done in England. Over the next 15 minutes or so we noticed people gathering around but thought nothing of it until the bus arrived. It was then a scramble of pushing and shoving to get on the bus - the sort of behaviour which might have led to an argument or worse in England - and we were the last to get on the bus.

However, once on the packed bus, it was noticeable how not one woman was standing.

Memetic evolution of cultures, just like the genetic evolution of species, sub-species and regional varieties, accounts for both the similarities and difference. This cannot be explained by a system of objective moral laws handed down by a magic man. And that also begs the question where did this magic man get them from? Is there an infinite regress of higher authorities handing down morals to the Christian god, or are they merely it's capricious and arbitrary whim? (See Xeno's Religious Paradox). Lewis conveniently neglects to explain how this assumed god fed these 'laws' to us. Did it feed them in slowly a little at a time as we evolved into modern humans? Did it provide them fully worked out to our pre-human ancestors, or did it decide one day that humans were now human enough so we could all be given a dose of moral laws? Obviously, this is all part of the 'mystery' element that we mere mortals shouldn't be concerning our selves with.

For more on memetic evolution of morality, see Religion: An Abdication Of Moral Responsibility.

Memetic evolution is the most vicarious explanation and does not need to invoke an unexplained, and unexplainable, magic or magician, or an infinite regress of higher authorities. All elements of the memetic theory of moral origins are there to be examined, tested and validated by scientific methodology. There is nothing which needs to be pared away with Occam's Razor because nothing is included merely to arrive at the desired conclusion or to pander to an audience.

Of course, memetic evolution doesn't provide comfort to those who need to feel a magic man is thinking about them and looking after their interests, nor those who like to imagine they alone have the one true culture given to them by the one true invisible friend, but then pandering to such desires should not be part of a scientific explanation even if it is a normal component of a theological one.

So, although we can forgive C.S.Lewis his ignorance of memes, writing as he was before they were discovered, we shouldn't overlook his arrogance. The basic mistake he made was in assuming that, because he couldn't think of a natural explanation for the origin of human morality, there couldn't be one, so the only explanation had to be supernatural.

Of course, as always with Lewis, there is the arrogant assumption of his class that the only possible supernatural explanation must be the god locally popular in England in 1952 - how could the English possibly have the wrong god? - hence his patronising tone and underlying assumption that us plebeians would simply accept what our social superior was telling us and not ask how he got from not knowing why we have societies based on morals to the conclusion that it must have been his favourite god. We could safely be relied on to take that for granted, just as people in culturally arrogant and parochially ignorant societies still can be today.
