Circular logic is circular in Evidence for God

Michael R. Licona, one of the editors of Evidence for God (the other being William A. Dembski) contributes Chapter 33, "Can We Be Certain That Jesus Died on a Cross? — A Look at the Ancient Practice of Crucifixion". Certainty in this matter is apparently important because if Jesus didn't die on a cross he couldn't have been resurrected, and "without a resurrection, Christianity is falsified." So Licona presents "four reasons that support the credibility of the claim that Jesus died as a result of being crucified."

First, he mentions reports about Jesus's execution, some by non-Christians, and he goes on to say:
The fact that these non-Christians mentioned Jesus in their writings shows that Jesus' death was known outside of Christian circles and was not something the Christians invented.
That's stretching it a bit. Licona himself states that the reports were late first century, early second century, early to mid-second century, and second to third century. Even the earliest would presumably have been decades after the event reported, so it's unlikely they were reliable eye-witness accounts. They could even have been second-hand reports based on the same source — but how reliable was that source itself? Maybe the story of Jesus's death was known outside of Christian circles, but the existence of those reports is hardly proof that they are all true.

Second, Licona goes into gory detail about crucifixion and concludes that people who were crucified were highly unlikely to survive it. I'm not sure why this needs to be stated — execution isn't something one is expected to survive.

Then we get this:
Third, professional medical opinions are unanimous in concluding that Jesus certainly died as a result of being crucified.7
Licona gives the following reference for the above statement:
7A number of these are mentioned in Raymond Brown, The Death of the Messiah, Volume 2 (New York: Doubleday, 1994), 1088ff.
Now, I'm not disputing that Jesus probably died as a result of his crucifixion, but I have to point out Licona's appallingly shoddy logic in the above claim. What, precisely, does he mean by "unanimous"? Has he consulted every professional medical opinion? Apparently not — he says "a number" are mentioned in his cited reference. It seems therefore that he's using "unanimous" in the sense that all of the professional medical opinions that conclude Jesus died from crucifixion are unanimous in that opinion — which is at best tautologous.

Licona may have been perilously close to the edge of logic with that last "reason", but with his fourth he steps right off the cliff. He attempts to use Jesus's post-mortem appearances as evidence for him dying on the cross. This is begging the question. What Licona is trying to establish in this chapter is that Jesus died on the cross, because if Jesus didn't die on the cross he couldn't have been resurrected. Licona can't use the resurrection as proof of the crucifixion and then use the crucifixion to prove the resurrection, because — this is elementary stuff — that's a circular argument.

Argumentation of such low calibre is fatal to Licona's credibility here. Dembski should have spiked it.

Sophisticated theologians circumvent Bible’s condemnation of homosexuality « Why Evolution Is True:
Jerry Coyne: "I’m starting to realize that there is no sophisticated theology." He's referring to a post by Jason Rosenhouse, who concludes with this on Leviticus:
"If you want to use the Bible as a moral guide then you are stuck with it. The text is not infinitely malleable, and you cannot reasonably interpret X to mean not X. Rather than try to twist the text to fit modern moral sensibilities, which despite their denials is precisely what Friedman and Dolansky are doing, why don't we simply discard this particular ancient book and move on to more promising approaches to morality?"
Amen!

* Yeah, he's my dad.

It's that man again — the Craig "itch"

Regular readers of this blog (and listeners to Skepticule Extra) will know that I have an oscillating attitude to William Lane Craig. No sooner have I concluded that he has nothing new to tell me and therefore I can forthwith ignore him, than I find myself irresistibly scratching at something he's said, knowing that it's wrong without being able to put my finger on precisely why. But I think Thunderf00t has nailed it:

http://youtu.be/4u6Mz21jTaA


Being a confident speaker will go a long, long way towards convincing people that what you say is true. If you behave in a way that says loudly and clearly that of course what you say is true, many people will believe you by default. But with Craig there is always that niggling doubt that his approach to his various arguments for the existence of God rests on something not just unsound but profoundly silly. This video exposes that doubt and parades it for all to see.

4thought.tv: "Should creationism be taught in schools?"

Back in June Channel 4's daily two-minute opinion film-clip slot, 4thought.tv, covered intelligent design. I blogged about it at the time, and we covered it on the Skepticule Extra podcast. A couple of weeks ago the subject was "Should creationism be taught in schools?"

Monday's clip was 18-year-old student Sam Scott Perry:

http://www.4thought.tv/themes/should-creationism-be-taught-in-schools/sam-scott-perry
Young Earth Creationist Sam Scott Perry believes the world is only between 6,000 to 10,000 years old and that dinosaurs roamed the land with humans. Sam thinks creationism should be included in schools in order to allow children to make up their own mind.
He believes that humans were formed from dust by God because that's what the Bible says, and wants creationism to be taught in schools in the interests of "fair and objective science." From these and other comments it's clear he has no notion of what science is — he admits that he gained his A* in GCSE Biology by writing the answers required even though he doesn't believe they are true. He believes humans walked with dinosaurs because dinosaurs are land animals and the Bible says that land animals and humans were created on the sixth day. This, according to Sam Scott Perry, is "logical". He also floats a weird conspiracy theory that creationism is not currently taught in schools because of fears it might convince people the Bible is true. Are his views typical of 18-year-old creationists? Perhaps not, but Channel 4 naturally go for the extreme case with which to start off this series.

Conspiracy theories are picked up by Tuesday's contributor, Stephen Law:

http://www.4thought.tv/themes/should-creationism-be-taught-in-schools/stephen-law
Stephen Law is a Lecturer in Philosophy who believes creationism is scientific nonsense. Stephen says it is wrong to teach children something he thinks is quite clearly false.
"Creationism is pernicious scientific nonsense." Stephen Law states simply that teaching creationism as fact is teaching things known not to be true, and goes on to suggest that clinging to the Biblical story of creation in the face of scientific evidence to the contrary could be interpreted as symptomatic of mental illness. (He has pointed out elsewhere that he didn't intend to imply that all creationists were mentally ill.)

Randall Hardy of "Creation Research" is another creationist who thinks that children should be allowed to make up their own minds:

http://www.4thought.tv/themes/should-creationism-be-taught-in-schools/randall-hardy
Creationist Randall Hardy wants children to be taught that God made the world in 6 days and rested on the 7th. Randall thinks evolutionists and atheists fear Creationism being taught in schools because children will find it convincing.
Creationists often play the "academic freedom" card, but in schools it's not appropriate to teach something that isn't accepted science. Otherwise the science curriculum would be full of phlogiston theory, the luminiferous aether, the four humours and all sorts of other unscientific stuff like alchemy and astrology. Students are free to investigate pseudo-science after school — they can even go on to study it at university. Randall Hardy displays appalling ignorance of evolution when he talks of cats bringing forth cats, dogs bringing forth dogs. He's also wrong when he claims people when they are born believe naturally in a creator. Leaving aside the fact that the existence of a belief has no bearing on whether that belief is true, what children are born with is an innate tendency to ascribe agency (to inanimate objects as well as people and animals). This is an evolved instinct — it supports evolution rather than creation.

Next we have Rev Canon Rosie Harper, who says that creationism is based on a literal reading of the Bible, and is an unnecessarily narrow viewpoint:

http://www.4thought.tv/themes/should-creationism-be-taught-in-schools/rev-canon-rosie-harper
Reverend Canon Rosie Harper believes teaching creationism to children is selling them short. Rosie thinks literal interpretations of the Bible are dangerously wrong-headed and risk bringing mainstream Christianity into disrepute.
She doesn't want creationism taught in schools, but she's one of those wishy-washy Anglicans about whom one might say, "there but for the grace of God goes an atheist." In this debate however, she's on the right side.

Laura Horner is the founder of CrISIS — Creationism In Schools Isn't Science:

http://www.4thought.tv/themes/should-creationism-be-taught-in-schools/laura-horner
Laura Horner is an Anglican and the founder of CrISIS; Creationism in Schools Isn’t Science. Laura started the group after a creationist movement visited her son’s school. Laura believes creationism discredits religion as much as it discredits science.
She's a Christian who believes creationism is bad religion as well as bad science, and makes the important point about valid science being falsifiable, while creationism isn't.

Saturday's clip was by Abdul Aziz, a maths teacher:

http://www.4thought.tv/themes/should-creationism-be-taught-in-schools/abdul-aziz
Muslim Abdul Aziz is a Maths Teacher who believes evolution is not convincing as a scientific theory. Abdul wants creationism presented alongside evolution in the classroom, so that children get the opportunity to make up their own minds.
He claims that belief in evolution is based on a "leap of faith" and comes out with the usual creationist micro/macro-evolution objection. His whole argument is one from ignorance — it appears he's never read a book about evolution (I'd suggest The Greatest Show on Earth by Richard Dawkins). He also says (like Randall Hardy) that children should be allowed to make up their own minds, which from a teacher is a shocking misunderstanding of what education is about.

Finally we have Michael Reiss, who does not want to see creationism taught in schools, but he's not averse to it being discussed (though thankfully not as a science in science lessons):

http://www.4thought.tv/themes/should-creationism-be-taught-in-schools/michael-reiss 
A Professor of Science Education at the Institute of Education, University of London, Michael Reiss welcomes open discussion of creationism in the classroom provided it is made clear that it has no scientific basis whatsoever.
He complains that some materialist scientists can't understand what it's like to have a religious faith. What he's implying, I think, is that a hard-line atheistic attitude is alienating children with creationist beliefs, to the extent that they will not be open to the scientific evidence. Michael Reiss made similar comments when he was the Royal Society's Director of Education, which caused a bit of an uproar, and shortly afterwards he stepped down from his post. Although the 4thought.tv website makes no mention of it (except, someone has noted it in the comments), Michael Reiss is a minister of religion.

Creationism does seem to bring the wackos out of the woodwork, as the comments on these clips show. I posted a brief comment on the first clip, and found myself in a protracted exchange with a user named Phillip, who — though extremely polite — seemed to have no conception of how to distinguish what's true from what's false.

Skepticule Extra 017 now available

Somewhat delayed, the 17th edition of Skepticule Extra is now available for listening. Go here for this delectable download:

http://www.skepticule.co.uk/2011/12/skepextra-017-20111113.html

The three Pauls deal actively with some feedback, then discuss some planned disruptive action to Remembrance Sunday, some libel action, some political action, and some concentrated apologetics action. It's an all-action episode...


An explanation that's nothing of the kind

Last week's Unbelievable? featured Edgar Andrews and Robert Stovold on "What made the Universe?" — a loaded question if ever there was one (though to be fair, host Justin Brierley admitted this). There was much about fine tuning and the Big Bang, and God being an uncaused cause. In other words, the usual stuff.


What I found disturbing is that Andrews seems to think that positing "Goddidit" is an adequate explanation. He says that unbelievers come up with all sorts of ad hoc arguments to explain such things as the Big Bang, the apparent design of the universe, how something can exist rather than nothing, and such-like, but these explanations are all separate and unrelated. (I'm not sure that's true, but we'll let it pass.) Andrews claims that positing an all-powerful, all-knowing, timeless, spaceless, uncaused intelligence (or to put it another way, Goddidit) explains all these separate things with a single entity — and presumably is therefore more likely to be correct*.

Andrews must have a very odd idea of what constitutes explanation. In general when we attempt to explain something we don't understand, we do so in terms of things we do understand. Saying "Goddidit" isn't only the worst kind of intellectual cop-out — in theological terms it exhibits stupendous hubris.

As Karl Popper pointed out, if you have a theory that fits all circumstances without exception, in that there's nothing it can't explain, it isn't an explanation at all.


* My competing theory — that magic pixies did it — is similarly unified, but I wouldn't call it an explanation. Edgar Andrews is on Unbelievable? again today. I'm not looking forward to it much.
