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.

A covering of feathers for the terrors of the night

How to struggle with the burden of other people's suffering.

It’s one of the sad facts of life: that many of us at some point will see our parents get old and fade away. Sigh. It doesn’t matter how well prepared you are or how much you’ve thought about it before hand, the reality of a fragile mum or an exhausted dad can break your heart.  

I’ve talked to my parents about this for years here and there. We’ve done lots of joking about seeing them off with a pink pill in the sherry, or ‘it’ll be a pillow for you Pa, if you’re too annoying’ – type thing. But when they left after Sunday lunch a couple of weeks ago, I had to clutch my husband. He lost his own mother last year… we’re still fluttering around the gap she’s left in our family. And now there’s my beloved olds too, looking diminished and moth eaten and moving at crepuscular speed. Ask Dad how he is these days, and he says ‘Old, dear’, and won’t elaborate further. 

I can cope with this when it’s in short bursts. Visiting them for lunch or taking them out on a trip is OK and manageable, and there is still joy in family occasions. Mum’s birthday was full of love, even though she took all afternoon to open her cards and became hopelessly confused about who’d given her what.  

But staying with them… that’s hard. Seeing the dust thick over the spare room; worrying about just how long that bowl of leftovers has been in the fridge. I whip about as unobtrusively as I can, scrubbing the bottom of the washing up bowl or putting their jerseys in a wash. I don’t want to be annoying – they won’t accept help and I’m not going to push – but it makes me sad. In particular I hate that my mum is in constant pain from crumbling bones, and that dementia has stolen her mind. Also, that as a consequence, Dad is irritable with her; he who has always adored her so much. 

I could picture them vividly, the feathers, soft and heavy and beautifully patterned like an owl’s, and imagine I was peering out through them at Mum’s pain.

Since childhood, I have struggled with the burden of other people’s suffering. I sometimes wonder if I’m exaggerating when I think about how much I mind, but I don’t think I am. I can only manage if I’m really ready for it. With my counselling clients that takes the form of very firm boundaries, regular supervision, colleagues to talk to etc… but with family it’s much harder. It’s just your own naked, soft-bodied self-shrinking from all the nettles and thorns – like a hermit crab without a shell.  

So when I went down to Mum and Dad’s this time, I felt the need to prepare. ‘Put on the armour of light,’ St Paul says, which sounds just the thing. I hardly slept last time, tossing and wriggling through small-hour horrors with my neck hurting and a feeling of tears not being far away. What to arm myself with though? 

The answer came in the form of an ancient poem - Psalm 91. I was listening to a Premier Radio presenter who is a pastor – a big, tattooed fellow with rings in his nose and lip – and he said it was his main defence when his wife was diagnosed with cancer. So, I looked it up, and I loved it. It was all about how the Lord will cover you with his wings and keep you safe from the terrors that visit in the night and the pestilence that stalks by day, or words to that effect.  

Malcolm Guite (a poet and priest whose writing I love) says you have to treat Psalm 91 with care: it was the one Satan tempted Christ within the wilderness, challenging him to throw himself from the temple roof and God would send his angels to catch him (as it says in the psalm). It’s not to be taken literally, this psalm: you can’t deliberately put yourself in harm’s way and expect to be immune because you’re a Christian, like some of the vehement anti-vaxxers around the world who think faith alone will protect them from lethal diseases. But the message is that if you put your trust in God, he won’t let you be damaged in any important or lasting way by the evils of the world. 

I memorised as much of it as I could. And then when I woke in the night – inevitably – with the dread hovering over me, I kept thinking, ‘The Lord will cover thee with his feathers’. I could picture them vividly, the feathers, soft and heavy and beautifully patterned like an owl’s, and imagine I was peering out through them at Mum’s pain and muddliness and Dad’s frustration and my own fear. They were like malevolent ghosts drifting through the dark, menacing and cruel. But Mum and Dad and I, our actual selves, were curled up safely, warm and hidden with the great wings over us.  

And eventually, I was able to go back to sleep.
