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.

Don’t die: the relentless pursuit of life

If there was a way beyond death, shouldn't we give up everything to find it?

Josh is a curate in London, and is completing a PhD in theology.

In the days before my daughter's birth, I was reading about the fear of death. Ernest Becker won a Pulitzer Prize in 1974 for his book The Denial of Death. In it, he argues that our lives are structured around the fear of death. In the posthumously published follow-up, Escape from Evil, Becker writes:

"Man wants to persevere as does any animal…but man is cursed with a burden no animal has to bear: he is conscious that his own end is inevitable."  

For Becker, human culture is really a series of attempts to avoid or transcend the reality of death. We follow charismatic leaders in the hope of becoming part of something greater. We have children in the hope that something of us will last beyond the span of one lifetime. We collude to marginalise pensioners and prisoners and any other reminders of our frailty, hiding them away so we can briefly pretend at immortality.  

Last week I thought of Becker when I watched Don’t Die: The Man Who Wants to Live Forever on Netflix. The documentary follows Bryan Johnson, who made his millions in tech and is now going to extremes to undo the impact of ageing on his body. An exacting routine of dieting, sleep, fitness and medication is augmented by riskier interventions, such as experimental gene therapies. 

As Johnson tells it, his past struggles with mental ill health and suicidal ideation led him to pursue a life less reliant on his mind. He seeks instead to listen to what his organs tell him they need via algorithms and diagnostics: fallible humanity corrected by data. 

Johnson is resolute that it is not fear of death that drives the enterprise but a desire to live, particularly to live as long as possible with his son. One of the documentary’s strangest and most touching scenes is an inter-generational plasma transfer. There is evidence that plasma from a younger donor can have a de-ageing effect on a recipients' organs. So, Bryan decides to give his dad some of his plasma and his son gives him some plasma. Each of the three men, we learn, have experienced isolation after leaving Mormonism. The transfer becomes a kind of founding of a family outside the faith they have each rejected and been rejected by. 

Johnson’s pursuit of longevity now plays an equivalent role in his life to that faith– not just as a source of belief and human purpose, but of human connection. The documentary ends with a montage of "Don't Die" communities around the world hiking and dancing and celebrating life together.  

In the months after my daughter's birth, I recognised something of what Becker names. Here is someone who will outlast me, something of me will transcend the limits of my life. And here is someone who reminds me of those limits. Here is this great gift and joy who will sit in the front row at my funeral: the embodiment of life’s goodness a witness to its end.  

Are we wrong to fear death? If there was a way beyond it, shouldn't we give up everything to find it?

There is more going on in Bryan Johnson and the wider de-ageing movement than Becker's analysis would perhaps allow. Fear of death is not the only story here. When is it ever, really? Fear only makes sense alongside—and in light of— goodness, life, gift. To fear loss, you must have something to lose.  

And yet, the story Becker tells about culture does seem to ring truer in the years since his death. As technology improves, death's denial becomes more convenient. As the natural world degrades, it becomes more compelling. And as wealthy men become wealthier still, their denial on behalf of us all becomes ever more creative.  

And who can blame us—any of us? Are we wrong to fear death? If there was a way beyond it, shouldn't we give up everything to find it? 

This Wednesday, Ash Wednesday, marks the beginning of Lent, the Christian season of reflection and self-denial. On Wednesday, I will receive an ash cross, and as I draw that same cross on forehead after forehead, I will repeat these words:  

"Remember you are dust and to dust you shall return,  
turn away from Sin and be faithful to Christ."  

I will hear the invitation, in my voice and not my own, to give up the futile theatrics of a deathless life. I will pray for the strength to live what I have spoken. I will say goodbye to those who I marked, each of us now a signpost to our shared mortality. And then I will go home to yoghurty hands, bathtime songs and giggles at the funny smudge on my face.
