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.

Coal’s demise teaches us to be cautious about progress

Why the extinguishing of coal power should dampen attitudes to what promises to be progress.

Chimneys. In our 1920s house, we have two of them, rising into the sky like solid brick antennae. Look across most big cities in the UK today and virtually every house still has them. Yet most of them remain idle, monuments of a bygone age. Useful for holding the TV aerial but not much else.  

I thought of chimneys recently when driving up the M1 past Ratcliffe-on-Soar Power Station. On the last day of September this year, it was disconnected from the national grid, as the UK’s last coal-fired power station. The age of coal was over. 

Back in the day, chimneys were busy. In the Industrial Revolution of the 1700s and 1800, coal was used to light towns, power railways, and fuel steam engines. By 1850 we were mining 62 million tonnes of coal every year. Coal was the fuel of the present, driving the technology of the future. Chimneys were a sign of a bright way ahead, churning out smoke from coal-fired factories and bringing safe fires into the hearth and home on those dark wintry northern European nights. Coal was leading us into the sunny uplands of prosperity, comfort and mastery over nature. The power behind the industrial revolution, it was as crucial to the present - and the future - as the smartphone seems to us today. 

It began to dawn on us we had a problem with coal during the Great Smog of London in 1952. A period of cold weather, an unusually high number of domestic coal fires, no wind and an anticyclone which acted like a thick, stifling blanket, all of it kept the soot-filled fumes from escaping into the atmosphere. As a result, a miasma of dense, smelly fog sat for days over London, killing thousands of people. It led to the Clean Air Acts of 1956 and 1968, banning emissions of black smoke and making residents of urban areas and operators of factories convert to smokeless fuel. Margaret Thatcher’s fight with the miners in 1982, leading to the closure of many pits, was another nail in the coffin of coal.  

In October 2001, the Large Combustion Plant Directive aimed to reduce carbon emissions throughout Europe. The UK planned to end coal use by 2025, and we managed to get there a year early. On the domestic level, not many of us use coal or wood fires anymore. Since May 2023, it has been illegal to sell ordinary domestic coal in the UK. Wet wood is banned too. You can burn what’s called ‘dry wood’, with 20% moisture or less, but you can’t go into the woods and bring home random logs you find on a weekend walk any more. Wood burners remain popular, yet even they are suspect, as they produce high levels of CO2.  

Gradually we realised that there was an order and a rhythm to the natural world that we messed with at our peril. There was, as Marilynne Robinson once called a ‘Givenness’ to the world. We simply had to learn to respect that givenness, that order, and live within the limits it placed upon us. And as a result, the chimneys lie idle. 

The demise of coal - and chimneys - teaches us a lesson. Not everything that promises progress is good. Wisdom lies not in pushing forward with whatever technology or new idea offers more choice, more possibility, but knowing what will diminish us and what will give us life.
