A Bayesian theory of death

The sinking of the superyacht displays the probability, and banality, of death.

On any statistical calculation, the probability of dying by drowning when your luxury yacht suddenly and inexplicably sinks at anchor in the Mediterranean has to be extremely low. 

So it’s the cruellest of ironies that tech tycoon Mike Lynch should so die, along with his daughter and five others, having devoted his commercial life to the application of such statistical probabilities. He had named his yacht Bayesian after the 18th-century theorem that introduced the idea that probability expresses a degree of belief in an event. 

That doesn’t expressly mean religious belief. But, intriguingly, it doesn’t exclude it either. According to Thomas Bayes, who published his theorem in 1763, the calculable degree of belief may be based on prior knowledge about an event, such as the results of previous experiments, or on personal beliefs about it. 

In essence, you don’t believe your yacht will capsize in the night and sink in seconds, because your experience tells you so. That belief can mathematically be included in the probability of it happening. 

We can transfer the method into religious praxis. Christian belief in the event of resurrection, for instance, can be calculated in the probability that the deaths of the Lynches and others aboard the Bayesian are not the end of their existence. 

It’s an intriguing legacy of Lynch’s work for theologians. But it’s the sheer lack of probability of the lethal event occurring at all that lends it its random banality. It’s that death visited those asleep on a yacht in the small hours that lends this news story such tireless legs, not just that these were super-rich masters and mistresses of the universe. 

There have been bitter observations on social media that the Bayesian’s victims have commanded limitlessly greater attention than the many thousands of refugees who die in small-boat crossings of the Mediterranean every year.  

This is a category mistake. And again, Bayesian theory can be deployed. Experience supports our belief that crossing the sea in overcrowded and unseaworthy vessels can all too often lead to tragically terminal events. The probability of death is plain. Again, it’s the sheer randomness of the Bayesian yacht event that sets it apart. 

If death can visit at any time, there can be no difference in the valuation of long or short lives. 

That randomness brings us back to the banality of sudden death among us, almost its ordinariness, something that just happens, often entirely out of the blue. The prayer book has the funeral words “in the midst of life we are in death”, meaning that death is our constant living companion. But that doesn’t quite cut it for me, because it tells us it’s there, but nothing of its true significance. 

The tenets of Christian faith are regularly said to be those of a death cult; that it’s a deep-seated fear of death that leads us to avoid it with assurances of eternal life. But it’s the sheer banality of death, as displayed in the randomness of the Bayesian event, that seems to knock down that idea. In its randomness, death looks ridiculous rather than evil. 

Conspiracy theories around the sinking of the Bayesian are a kind of denial of the reality of death too. We want there to be more to it than the utterly banal.

Author Hannah Arendt coined the phrase “the banality of evil” when covering the trial of Nazi holocaust architect Adolf Eichmann in Jerusalem. I’d want to suggest that it’s that same banality, that basic human ordinariness, that is the real nature of the supposed grim reaper, rather than his evil.   

None of this can comfort the Lynch family, who mourn the loss of a much-loved father and his young daughter, or the families of the others who lost their lives on the Bayesian. But it is meant to go some way towards an explanation of what we mean in Christian theology when we bandy about phrases such as “the defeat of death”. Because it’s not a wicked serpent that’s been defeated, more of a pointless clown. 

There is something especially painful about the death of the young, such as that of 18-year-old Hannah Lynch on the Bayesian that night, a young woman on the threshold of life. And – God knows – the even younger lives we’ve read about being taken lately. 

But the concept of banality may lead us to another tenet of faith: The completeness of every life. If death can visit at any time, there can be no difference in the valuation of long or short lives.  

A poem, often ascribed to a former dean of St Paul’s cathedral, begins with the line: “Death is nothing at all.” That’s wrong, as an idea. Death is as significant an event as birth. But its defeat is in keeping it in its place. 

The dignity in simplicity with which football manager Sven-Göran Eriksson greeted his final illness is a masterclass in this tactic for life. Death isn’t to be negotiated, it’s just there. 

In the end, death isn’t a Bayesian probability, it’s a certainty, for all of us. The difference, in Bayesian theory, must be the belief we bring to our personal calculations of the probability of the event.

America: two nations under God?

Red, blue, and rarely purple.

I've just come back from the USA. A few days on the east coast was a chance to take the temperature of America after its recent election, a brief impressionistic sense from conversations, reading the runes – and the blogs. In short, I had heard much about the divided state of America. I didn’t realise quite how divided it was.  

America has always made a great deal of unity. The vision for the USA imagined immigrants from different nations across the world invited to forge a new life in a new continent, leaving behind the divisions of the old world. It was the coming together of varied States across the vast continent into one Union. The language is everywhere. Most cities have a ‘Union Square’, Street or Turnpike. The chosen name itself was the United States of America. The slogan E pluribus unum – “out of many, one” was first featured on the original 1776 design of the Great Seal of the United States and formally adopted by the U.S. Congress as the nation's official motto in 1782. The American civil war of the nineteenth century was such a trauma for the nation precisely because it threatened that union. “One nation under God” says the pledge of allegiance, recited by every American child. Yet today it feels that a more realistic description would be two nations under God. The Disunited States of America. 

The split is pretty even. 73.7m people voted Democrat. 76.4m voted Republican. That itself is no great cause for alarm. What does cause alarm is the utter divide between the two groups. New York, for example. is pretty solidly Democrat. Someone who voted Trump told me they would never admit to it publicly because of the public shame it would bring. The same is true in the red states. To admit you voted Democrat in some Southern Baptist churches in Texas would be to invite social ostracism. Many Evangelical pastors who have their doubts about Trump have to keep quiet otherwise they would lose the support of their congregations and quite possibly their jobs. As a result, the only Evangelicals that tend to criticise Trump will be academics or journalists who have little to lose. 

As a taxi driver joked, if a young Democrat goes out on a date with someone they've met on Tinder, and discover their partner voted Republican, there is unlikely to be a second date. A Christian visitor centre in Washington DC tells me that they are looking forward to Trump being President again, because the flow of evangelical Republicans visiting the capital dried up during the past four years as they felt it was Biden’s town. It’s well known that nearly 80 per cent of white Evangelicals voted for Donald Trump. Such families were more likely to come to DC to see the seat of government if they knew ‘their guy’ was in the White House.  

It seems that in the current version of the USA, who you voted for is the number one identity marker. And the two groups rarely talk. In New York I preached in an Episcopal church. The Bible readings for the day spoke of ‘wars and rumours of wars’ – ‘everything will be thrown down’ – apocalyptic texts that invited me to talk about the election in the light of Jesus. Beforehand I asked the Rector what the voting pattern of the church was. “It’s genuinely purple” he said – “a mix of red and blue, Republican and Democrat, Trump and Harris. At least here they do talk to each other.” That seemed a rare thing in this deeply divided country.  

Jesus once said: “Every kingdom divided against itself will be ruined, and every city or household divided against itself will not stand.” Trump may well fix the economy and illegal immigration. Yet such deep division, especially in a nation whose identity rests of unity is perhaps a more existential threat.
