Did Christianity Spell the End of Classical Civilisation?

I recently received an email, several in fact, from a correspondent who believed that Christianity caused the fall of classical civilisation. His emails were prompted by some of the material on my website that shows the positive effect that Christianity has had on science. He followed his original email with several more which contained many quotations from historians and the primary sources like the Theodosian Code. He even included a couple of lines from our friend and regular poster Charles Freeman.

Here is an excerpt from a rather longer email that he sent me:

The Christian devout try very hard to rescue their religion from the bitter reproach that its advent caused the eclipse of learning and science in the West for many centuries. They claim Christianity preserved the remnants of classical learning during the barbarian era, so far from being guilty of destroying it.

I think this is a rather desperate apologia. It seems unconvincing to hold the barbarians responsible for so many centuries of darkness in terms of learning and science. It requires us to believe that the classical world, so sophisticated in its intellectual culture, with such vast intellectual and cultural resources, was largely wiped out by barbarian invasions, and took many many centuries to recover.

It is much more likely that, absent some other deculturising factor, the unsettlement caused by the barbarians would have been relatively brief, the barbarians would have been absorbed by the superior civilisation, and the process of intellectual development would have resumed. But of course there was another factor present, and that was the takeover of Western society by the Church. There is no doubt that the Church was bitterly hostile to the intellectual and cultural presence and challenge posed by Graeco-Roman polytheism. To conquer the populace securely for the new faith, it would have had to resort to vast and sustained destruction of the classical heritage. That was the only way in which it could have prevented itself from being absorbed by the old culture. We know from the historical record that Christian destruction of the classical temples and texts was on a huge scale. This is surely not contested by yourself. We know that the destruction was on such a vast scale that in the end it took the transmission by the Arabs of the classical texts, many centuries later, for sustained learning to resumed in the West in a big way.


Far from being an non-believer, my correspondent is a Hindu and sees parallels between his own religion and ancient paganism. I don't know enough about the Hindu pantheon to comment on this, but it may account for some of the evident sympathy that he feels for paganism. It may also account for the fact that he makes a fundamental mistake about Christianity's role in late antiquity. Despite the fact that Tim O'Neill has corrected this misapprehension many times, I want to note the error again because it is so widespread. Indeed, Freeman himself wrote an entire book, The Closing of the Western Mind, which is simply the age old mistake in extra-long format.

Christianity did destroy ancient paganism. It caused enormous damage to many wonderful works of art and fine buildings. Even the art and architecture produced in the name of Christianity can scarcely hide the fact that if you happen to prefer classicism to gothic, the end of paganism was an aesthetic set back. It also seems likely that many pagan religious texts have been lost, although judging by the survivals, such as the Hermetic corpus, this is rather less of a misfortune. And it is false to say that Christians targeted pagan literature. Indeed, they preserved some of the best of it including Homer and Virgil, despite these epic's explicitly polytheistic subject matter.

The central confusion of my correspondent, of Charles Freeman and of so many others is to imagine that a campaign against pagan religion should have caused a decline in science. It is just assumed that ancient paganism and ancient science were one and the same. But they had almost nothing to do with each other. O'Neill puts it better than anyone:

As a humanist with a fondness for most aspects of the ancient and Medieval past, I'd certainly lament the destruction of pretty buildings. And the oppression of pagans by Christians is about the same as the oppression of Christians by pagans to me, since (i) I'm a non-believer and (ii) I avoid value judgements about the supposed sins of the distant past. But how "mounting evidence" that Christians closed down the irrational, superstituous cults of their religious rivals and no longer allowed painted priests to shake rattles and intone chants at incense-wreathed statues of Olympian gods somehow supports your thesis I really can't fathom. The fact that the Flamen Dialis in Rome could no longer wear his magical hat, no longer observed his strange taboos against touching raw meat or beans and no longer had to carefully guard against sleeping in a bed whose legs were smeared with clay (?!) may be sad if you're into that kind of thing, but I can't see what the death of such weird superstitions have to do with any argument about rationality.


I would add that the similar level of cultural vandalism that accompanied the Reformation in England, when a large chunk of the country's medieval heritage was trashed, appears in no way to have set back the development of science. And why should it? Knocking down temples does not cause men to stop studying mathematics. Melting down reliquaries does not impact the advance of physics. And banning ancient rituals does not encompass holding back scientific advance.

Finally, my correspondent suggests that a pagan Roman Empire would have been better able to absorb the barbarian invasions than the Christian one could. This is an interesting reversal of the historical orthodoxy that Christianity helped produce a united polity that allowed the Empire to survive another thousand years in the East. But that is for another post.

Group selection: why I now think it is important

Group selection has been out of fashion for a while, subject to withering attack by Richard Dawkins and others. In general, I found the criticisms of Dawkins convincing and so missed the point of group selection. But as Jeff Schloss pointed out in his talk at the Faraday Institute that I noted last week, modern group selection theory is different from the now discredited idea that groups themselves can be selected for (and Dawkins is correct to dismiss this idea). However, there is an alternative sort of group selection that makes a great deal of sense and is fully compatible with the neo-Darwinian emphasis on the gene a the unit of selection. Today, these ideas are most associated with David Sloan Wilson, but my treatment shamelessly rips off what Jeff had to say at the Faraday.

Instead of groups, let’s think about football teams. Consider first, a rubbish team. We’ll call them England. The manager of England pays only for each goal that a player scores. As a result, all the players are desperate to score, but never pass the ball. This means that England are not very good. Consider second, a good team which we’ll call Spain. Players in this team also get paid for scoring goals, but less per score. But, additionally, the manager of Spain pays the whole team a bonus if they win, such that he expects his wages bill to be the same as England's. As a result, Spanish players pass the ball a lot to maximise the team’s goal scoring chances. This means that Spain are much better than England and each player actually scores more goals.

Now group selection says that your reproductive chances are boosted when you are a member of a successful group just as you’ll score more often if you are a member of a successful football team. Indeed, your reproductive chances are also increased if you are a member of a successful football team. In other words, the group forms part of the environment within which the individual’s genes are selected and genes that help the group will be favoured. So in Spain genes for passing the ball are favoured over those of selfishly trying to score yourself.

But as the group favours particular genes (or distributions of genes), the nature of the group itself will change over time and evolve. Just as a football team has room for strikers and midfield play-makers, so groups can accommodate different kinds of individual. This means that in a limited sense the group can be subject to natural selection, at least relative to other groups, such that it is fair to speak of group selection.

We can fruitfully speculate that altruism within the group, even altruism that does not directly favour the genes of each individual, could evolve in these circumstances. And it seems just as likely, as David Sloan Wilson has proposed, that group selection can help to account for some of the complex of behaviours associated with religion.

Tony Judt, whom I wrote about a few months ago, has died. Like many of the secular left, he was a good man who could not understand why his fellow human beings would not live up to the ideals he set for them. And his criticism of US policy towards Israel sometimes veered too close to being a conspiracy theory.

There is an appreciation in the Observer today.

2010 Faraday Lectures

Following on from my post on the Faraday Summer Course below, here are links to some of the other talks. Unfortunately, not all of them were filmed so some are available only in audio (for copyright reasons, I understand). Search for "Summer Course 5".

Royal Excess

In these times of fiscal austerity it’s perhaps worth contemplating the excesses of British Royal Courts of both the Tudors and Stuarts. When the Earl of Danby introduced measures to restore the fiscal credit of Charles II’s regime there was one area he failed to penetrate; the royal household. Charles was especially generous to his favourite mistress Barbara Palmer, the Countess of Castlemaine and the 1st duchess of Cleveland. The Countess was awarded her salary as a lady of the queen’s bedchamber of at least £200 pounds a year; in other words Charles forced his wife to accept his favourite mistress as a lady in waiting. He also paid her:
  • Ten thousand pounds a year out of customs revenue;
  • Ten thousand pounds a year out of the beer and ale excise;
  • Five thousand pounds a year out of the post office;
  • A thousand pounds a year out of first fruits and tenths (a tax which used to go from the clergy to the Pope).
  • Individual debts which were amounts that ranged up to thirty thousand pounds. These were mostly gambling debts.
  • Grants of royal lands and the right to dispose of and sell places in the customs.
Castlemaine was only the most prominent of an army of mistresses, courtier and household servants, all of whom had their hands in Charles's pockets. You might say it’s a good thing we don’t still operate this kind of system. Imagine having to pay a subsidy to Camilla Parker Bowles or Monica Lewinsky every time you send a letter or buy a pack of beers. Mind you there was that Tory MP who claimed for the £1,645 duck house.

My week at the Faraday Institute for Science and Religion

I spent the week before last at a Summer Course at the Faraday Institute where I gave a presentation on the importance of medieval science. I had a wonderful time, meeting loads of people who ranged from legendary academics like Ernan McMullin and Simon Conway Morris, to ordinary people who are just interested in the topic of science and religion.

Unfortunately, work commitments prevented me from attending all the talks. But, of those that I did make, the stand out presentations included the following (in no particular order):

Professor Peter Harrison of the University of Oxford, spoke about science and religion in the early modern period and gave a fantastic introduction to the topic. He was particularly interesting on how religious commitments could legitimate and inform scientific investigation.

Professor Jeff Schloss from Westmonst College gave a fascinating talk about the evolution of altruism and the various theories that have been put forward to account for it. His comments on group selection (which I now finally understand) explained how Richard Dawkins has got the wrong end of the stick over this issue. Time for me to revisit David Sloan Wilson's work in this area since I had previously been convinced by Dawkins' critique.

Professor Peter Clark from the University of Lausanne made the case for a physical theory of the mind being compatible with Christianity and the Resurrection. I agree with him that it is compatible, although I’m still something of a dualist myself. But Peter said he thought many Protestant theologians had now accepted a physical mind (what is technically called monism as opposed to dualism) as linking biblical doctrine to modern science most effectively.

These talks will soon be available on the Faraday Institute website as videos. I’ll post a link when they are up.
