Digging for Manuscripts

There is an interesting article in the Times about the Villa of the Papyri in Herculaneum. Most readers will know that this is a building, first excavated in the eighteenth century, which gave up an entire ancient library of some 3,000 scrolls. Using modern technology, we can read them (they were badly damaged in the eruption of Vesuvius that buried the villa). In general, the contents of the scrolls have been a big disappointment for amateur classicists as they mainly contain deservedly forgotten works of philosophy and poetry. Some good stuff has turned up, but precious little.

I find all this darkly amusing. People imagine the ancient world's literature must have been amazing and the fact we have lost so much a complete tragedy. Well, it is a pity. But the fact is that the stuff that was preserved are, in the main, the best bits. Their survival is precisely because they were valued more highly and more likely to be copied. True, quite a lot of dross survived too. In general, though, the discoveries from papyri have either confirmed what we already know, or shown that we have missed less than we thought. I've blogged previously about Menander and how his rediscovery in the sands of Egypt was a serious let down. We have since learnt to appreciate his shallow little comedies for what they are, rather than what we hoped they would be.

The Times article speculates about what manuscript treasures might still lurk in the villa of papyri. Digging there will shortly resume although there is no guarantee that there is another library to be found. All classicists have a wish list of what texts they'd like to recover. For me it is largely history rather than science or literature. Top of my list, though, would be Luke/Acts. Given the villa was destroyed in 79AD, the discovery of a Gospel would finally put paid to the arguments that these documents are too late to be reliable.

Professor Watson in Trouble

I have never had much time for James Watson or Francis Crick. They seemed to me to combine overbearing arrogance with over achievement. The treatment of Rosalind Franklin and the way she was airbrushed out of history still causes my hackles to rise, even though the picture has now been largely corrected. Both Watson and Crick were also neo-atheists before the event. Watson is quoted in The God Delusion, IIRC, as finding theists so embarrassing that he has no idea what to say to them.

So the I allowed myself half a smile at how he has come a cropper with some inflammatory remarks about race and IQ. Any one who bases conclusions about general intelligence on the outcome of IQ tests is being extremely foolish. Richard Dawkins himself has been uncharacteristically silent over Watson's defenestration, but his familar Sue Blackmore did try to defend him up to a point.

The most interesting article is in today's Guardian because it sheds some historical light on the whole matter. Johnjoe McFadden looks at the history of the eugenics movement. The supporters of eugenics are a role call of prewar 'freethinkers': George Bernard Shaw, H.G. Wells, Marie Stopes and Virgina Woolf. What the article does not tell us is that both Catholic and Protestant Churches fought hard and ultimately successfully for the human rights of the handicapped, disadvantaged and mentally ill. However, the death blow to eugenics was the Nazis actually doing what English progressives only talked about. Only by changing sides have freethinkers been able to get onto the right side of this argument and start to champion universal human rights themselves. Watson, perhaps, never realised that the world has moved on.

Why do Religious People give more to Charity?

An increasing body of research is showing that, on average, religious people are happier, healthier and more generous, at least in the United States.

This has been a bitter pill for some non-believers to swallow, but before we draw too much from these results, we have to ask a vital question: what is causing what? Readers will recall my praise of Jonathan Haidt’s article on Edge.org which touched on these questions. Aside from Sam Harris’s rant, this drew some more measured criticism. A correspondent pointed out Mark D. Hauser’s response which suggests that religion need not be a cause of the way religious people behave. Granted that religious people give more to charity, as Haidt pointed out, how do we know that religion is the cause of this generosity? Perhaps the sort of people attracted to religion are simply more likely to give to charity any way. Perhaps religious people are happier not because of their beliefs but because they lack the atheist’s clear-eyed pessimism.

Of course, we have been here before. We used to imagine that children grew up like their parents because of the way their parents raised them. Science poured cold water on this idea and has shown than nurture is irrelevant – it’s the parents’ genes that count. We also know that a predisposition towards religious belief or the lack of it is heritable. So, if the genes that give someone proclivity to believe in God also give them a tendency towards looser purse strings, we could not say that religion itself makes people generous. This might sound like a long shot, but we cannot dismiss the possibility without subjecting it to rigorous testing. We need to find out if religious people whose parents were non-believers have pockets as deep as those who were born to religious parents. Likewise, atheists with godly ancestors should be tested against those from a line of sceptics. If religion itself is a cause of generosity, health or happiness, the atheists should score the same, regardless of who their parents were. Likewise, with religious people from different backgrounds. As we already know that upbringing makes no difference to these traits and genes were ruled out by the experiment, we could be confident that religion itself was the deciding factor. In that case, non-believers would have to accept that religion has real benefits.

Of course, none of this has much impact on the question of whether or not a religion is true. Neo-atheists, like the right-wing Thatcherites as they dismantled Britain’s uncompetitive industrial sector, may have to tell themselves, “We may not be very nice, but at least we are right.”

Pity the Rabbits

I like rabbits. Not as pets, where they are a waste of perfectly good carrots. Instead, I like to see them hopping around misty fields first thing in the morning and making the countryside seem full of life. I am also extremely fond of casseroling them although for eating it is better to search out a French farmed rabbit instead of the English wild ones that the local farmers practically give away.

Late last week, I had to catch a train into London, but the car park at the station was full, as usual. No problem for me as I knew a little country lane where I could leave my car for free. After my business in town, I walked back down the little lane towards my car and saw a rabbit ahead. Strangely, it ignored me. When I got really close, it hopped forlornly around my feet without making any effort to get away. This was clearly a very unhappy bunny.

Next day, the set up was the same and with my car parked in the lane, I was walking back up towards the station. There was my rabbit again, but this time it was a great deal thinner. Standing in the middle of the road had led to its inevitable meeting with a car (mine, for all I know). I've seen plenty of squashed animals but this one was quite disturbing. Its eye, which I hadn't seen from above the night before, was swollen up and completely closed by a pink callous. Death by tyre had been merciful.

It was not until later that I learnt the terrible truth about my rabbit. The excellent Rod Liddle, one of my favourite journalists, had had a similar encounter and he knew what it meant. Myxomatosis is back. It arrived in the 1950s when it wiped out most of the English rabbit population, not to mention many of the animals that feed on rabbits and can't get hold of the French farmed ones. Liddle has set out the horrible details of this disease in his article so I won't repeat them here. The resurgence of myxomatosis is evolution in action. The few rabbits that survived the 1950s outbreak had a high degree of immunity. The virus survived but only gave them a bad dose of flu rather than a lingering death. But the genome of the virus has been clicking away like a rubic cube looking for the combination that will get it past the rabbit's immunity. Rabbits may breed like rabbits, but they have nothing on a virus. It was only a matter of time.

Now, they are dying. My wife has noticed it even if the news media has not. No one knows how bad it will get but it is likely that the misty mornings will be still next summer. And if you see a rabbit transfixed in your headlights, running it over is probably the kindest thing you could do.

Religion and Politics

With the prospect of a general election in the UK looking ever more likely, I thought I'd have a look at the religious beliefs of Gordon Brown (the Labour prime minister) and David Cameron (the opposition Conservative leader).

Former prime minister Tony Blair, of course, was a devout Christian in the Anglo-Catholic tradition. His wife is Catholic and Blair's conversion has been long anticipated (although equally long-delayed). However, he was careful to keep religion out of the political sphere. I saw him refer to it just once, years ago when he was still relatively unknown. On a TV show he explained his opposition to the death penalty in terms of his Christian faith.

Gordon Brown is, if anything, even more devout than Blair. His father was a Church of Scotland minister and his ethos is strongly Puritan. Today's European social democratic parties owe much of their philosophy to nineteenth-century Methodists and non-conformist Protestants. Brown's Christianity is very much in that tradition. He is teetotal, echoing the temperance campaigns of the early twentieth century, and very serious in demeanour. However, even more than Brown, he keeps his religion under wraps. No one really knows where he stands on abortion and gay rights, although he has abstained from all anti-gay discrimination measures put before the UK Parliament in the last decade. All this has made him a cipher for the secular left, like Johann Hari, who desperately hope his Christianity won't make an appearance. Given the tradition that Brown comes from, their fears are probably groundless.

David Cameron also claims to be religious. He told the BBC, "I believe in God and I try to get to church more than Christmas and Easter, but perhaps not as often as I should, but I don't feel I have a direct line." In this sense, his views are very much along the lines of most of the British who have a very relaxed view about religion, but on balance do believe in something. Again, commentators like Michael Portillo are hoping that any religious views he does have remain on the back-burner. In Cameron's case, I can't see him ever mentioning God on the stump. His beliefs are both fuzzy and unfocused without any philosophical depth.

Thus, if we do have a general election, both major parties have leaders with broadly Christian credentials. Although, Brown's are much stronger, I doubt a Conservative government would give any comfort to the neo-atheist tendency, nor cause them much concern.

More from Michael F. Flynn

As well as his fictional account of John Buridan's activities in fourteenth century Paris (reviewed on Friday), Flynn also included a non-fiction piece in the same issue of Analog. Rather than simply write an article lauding the achievements of medieval science, Flynn arranged his material into the same form as the Questiones found in the Summa of Thomas Aquinas and many other authors besides. However, instead of asking "Whether God is able to move the world with rectilinear motion", Flynn's questions are along the lines of "Whether the Middle Ages were an Age of Reason" or "Whether the scientific revolution could have occurred without the work of the late medieval natural philosophers."

In answering these questions and the related objections, Flynn marshals and impressive amount of knowledge and many quotations from today's historians of science. Overall, I think he defends medieval science very effectively although I would not agree with all his conclusions, most obviously on whether we can fairly say that there was a scientific revolution at all.

Still, the most valuable lesson I learnt from Flynn's attempt at the Questiones format is why reading medieval natural philosophy is such a strain. Certainly, the form allows a lot of information to be packaged neatly and compactly. But the result is incredibly dry. Even a writer of Flynn's skill is unable to make his questions any more palatable than a set of lecture notes. Medieval Questiones are like those business textbooks with numbered paragraphs. No one reads them for fun. I am not sure how many of Analog's readers will struggle through to the end. Those that do will make it because of the fascinating material rather than the Questiones themselves. As a piece of writing, the story of the fictional antics of young Oresme is far more effective.

The Last Witch to be Executed

At the start of my article about the end of the witch trials, I state that the last execution took place in 1782 in Glarus, Switzerland. This fact appears in almost everything ever written about the trials but I previously knew nothing specific about the event. The other day, the BBC aired a programme on Radio 4 about this final executed 'witch' (with an accompanying article here). She was called Anna Goeldi and her story is one of jealousy and class-politics rather than witchcraft. Her confession, extracted under torture, was a succession of cliches which should have convinced no one. But influential people wanted her dead. Today, there is a campaign for her to be officially acquitted or pardoned, which the authorities are resisting, as authorities do. I think this is a mistake. Not long ago, after decades of prevarication, the British Government issued a blanket pardon for all the deserters executed during the First World War. This was a humane act and I don't see why the authorities in Glarus feel it is worth defending a conviction for witchcraft.

A few posts ago, I asked why there are no right-wing conspiracies. I was put in my place by the comments, but it has also occurred to me that the witch craze, originating in learned books by theologians, was the ultimate conservative conspiracy and one of the most damaging.

De Revolutione scientarum in 'media tempestas' by Michael F. Flynn

Michael Flynn's novella (the title of which means, Concerning the Scientific Revolution of the Middle Ages) appeared in the July/August edition of the magazine Analog Science Fiction and Fact. By the kind auspices of the author, I've been able to read it and can only say it has been a long time since I enjoyed anything more.

Flynn is a noted science fiction author and shares my passion for the Middle Ages. His story is set in Paris during the late 1430s where John Buridan is the rector of the university. He has two precocious students - Nicole Oresme and Albert of Saxony. Of these seminal figures, historians know very little beyond the basic events of their lives and their highly technical works. Flynn fills in the details of their appearances and personalities, taking his lead from the fact that the three came from Picardy, Normany and Germany respectively. One day, William of Heytesbury, an Englishman and one of the Merton Calculators, comes to visit and the four of them decide to carry out Galileo's experiments on falling weights.

Two things made this a story come alive for me. The first is Flynn's skill as a writer. He uses the present tense throughout to convey a sense of immediacy and mines the humour inherent in the relationship between Buridan's two students. To some extent, any decent author could have done this, but Flynn's other achievement is nearly miraculous - he manages to transport the scientific revolution to the fourteenth century with almost no sense of anachronism. He can do this because he knows the minds of his protagonists and understands medieval natural philosophy. The anachronisms that remain are entirely deliberate and fashioned into a series of in-jokes. In comparison, I found The Name of the Rose deeply unsatisfying because Umberto Eco had no comprehension of medieval life and his main character was simply a cipher for the twentieth century vision of the Middle Ages. Flynn knows his stuff and so his own rewriting of history is far more convincing.

Thus, his novella is probably the best entry point to medieval natural philosophy I have read. It is also enormous fun and heartily recommended.

The Undercover Economist by Tim Harford

Tim Harford, a columnist for the Financial Times, would make a very good economics professor. His book, The Undercover Economist, is essentially a textbook intended to explain various fundamental concepts of the dismal science. But the combination of a lively style and lots of examples from every day life make this one of the best introductions to an academic subject that I've read. In fact, I imagine that many readers will have no idea that they have been introduced to an academic subject, so light is Harford's touch.

He explains why supermarkets make their budget ranges look grottier than they really are. They don't want rich people to buy them. Instead, wealthy customers are steered towards organic, free-range and fair trade products. We learn why free trade is always a good thing and also why most people find the concept so hard to grasp. Harford makes a powerful case for road pricing so that car users pay for the damage they do with each additional mile they drive at rush hour. His 'told-you-so' attitude to the dot.com boom is faintly nauseating because he gives little indication he did tell us before it fell apart. But overall, this is one of the books I'd make people read before giving them a licence to vote.

What struck me most about the book, though, was that it takes the triumph of free-market economics completed for granted. There is some stuff in defence of globalisation, but otherwise Harford makes no effort to debunk socialism or even Keynesian demand management. The latter was still part of the accountancy exam syllabus when I sat it in 1994. No more, I expect. For all the sound and fury from Naomi Klein and her ilk, the market really does seem to have swept all before it.

What's In a Name?

Yesterday, I came across a new word on the Guardian's comment is free web page. "Troofer", as in "the troof is out there," is apparently a derogatory term for a conspiracy theorist. As conspiracy theorists are, in my opinion, fairly low down in the intellectual food chain, I thought this word might be worth adopting. I'd still like a good term for the troofers who claim that Jesus never existed, although it seems Jesus Myther is going to stick.

The disciples of Richard Dawkins are another group in need of a name. What should we call the Dawkinistas if not Dawkinistas (which doesn't seem to have caught on)? Neither new atheists nor neo-atheists really do it for me, although that is what they tend to call themselves. Would the simple term Dawks be considered too rude? It's better than Brights anyway.

Looking at the biggest conspiracy theories out there - 9/11, Diana, Holy Blood, Kennedy, Shakespeare - I am struck that they all seem to be promulgated by the left. Why don't conservatives have any conspiracy theories? It seems most unfair. Apart from the belief that the media are a bunch of lily-livered liberals, conservatives just don't have a decent paranoid delusion to their names. Are they just too sensible to believe in them? Or maybe believing in conspiracy theories is all part of being anti-establishment.

On other matters, I've rejigged the blog to allow various feeds and networking options. It looks a bit ugly at the moment, I'm afraid. I tried the new blogger templates but that just made my blog look the same as everyone else's. Also, regular reader Bjorn-Are has started an English-language blog called B.A.D. Blog. He always has something interesting to say. I want to compile a blog roll of my own, so if you have a blog and especially if you link here, let me know in the comments.
