A Bayesian theory of death

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

The search for the Bayesian.
Vigili del Fuoco.

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.

Conviction politics is changing morality

Political dialogue gives way to animal-like culture war.

“We're gathering 100 MILLION signatures to OVERTURN Trump's wrongful conviction!” 

I received this SMS message, along with a link, on Monday 10th June. It was the fourth message of its kind I’d received since the verdict convicting former US President Donald Trump of felony. This time, out of curiosity I followed the link. I found a lot of words in capital letters conveying a sense of extreme urgency, but I did not find any evidence or argument for the injustice of the verdict. 

Trump’s conviction has been met with a torrent of reactions from people across the political spectrum. Everyone sees the event as an episode in the upcoming US election in which Trump plans to run for president. For those on the left, it’s final and conclusive proof that he is unfit for office; the evidence is clear, the courts have decided, end of story. For those on the right, it’s a further sign of the depraved depths to which the Democrats will go to discredit him; the jury was rigged, and the whole thing was a political stunt to win the election. The legitimacy of the court ruling is something nobody on the left questions and nobody on the right admits. 

To me, these responses are another sign of the ever-widening gap between left and right that eats up all common ground, even the rule of law. Political victory now takes priority over truth or justice – or perhaps more accurately: victory for my side is identical with truth and justice. To concede anything to the opposing side is seen, not as praiseworthy, but as betrayal.  

My comments in what follows are nonpartisan: I want to point to what is true of both sides equally: the failure of dialogue and its replacement by a warfare mentality. This change affects even what we consider moral and admirable behaviour. It is not only a problem in the US. Ever since Brexit, things have become increasingly polarised in the UK as well. 

That is what “culture war” means. War and dialogue are opposites; war is what happens when dialogue has failed.

Formerly in Western nations, rival political parties offered different means to achieve the same end: a flourishing society of justice, peace, prosperity, and freedom. Politicians disagreed but they respected each other. They had faith in the political process in which they all participated. Consider as an example the letter George Bush Senior left Bill Clinton after losing the 1992 US election.  

“Your success now is our country’s success,” he wrote. “I am rooting hard for you. Good luck.”  

The fact that he was now president was more important than which political party he belonged to. 

In such a cohesive society, the legal system was a trusted arbitrator whose decisions would be accepted by victor and loser alike. This does not mean the system was perfect. Everyone knew that justice could sometimes miscarry. But the public did not see themselves as qualified to judge that either way. How could they expect to know more than the jury? 

What we are witnessing now is a return to a more animal-like state in which the goal is that my team wins no matter what. If the arbitrator rules in favour of my tribe, they are seen as executing justice. If they rule against my tribe, their ruling must by definition be unjust. 

That is what “culture war” means. War and dialogue are opposites; war is what happens when dialogue has failed because both sides have been unable even to “agree to disagree.” 

Reasoned debate is seen as no longer effective in light of the vile underhanded tactics of the other side (but not, of course, of my side). 

In dialogue, both sides aim to uncover the truth even if the truth turns out not to be what I wanted or thought. Prioritizing the truth means that I might realise I was wrong and concede the point, even at some material cost. For example, in a property dispute, I might become persuaded of the truth of my opponent’s case and give up my claim. That may be painful, but winning was less important than justice being done. In dialogue, both ‘sides’ are really on the same side because they both ultimately want the same thing. 

In war, on the other hand, the goal is to defeat the enemy and it makes no difference whether they are right or wrong – or rather, it is assumed without question that they are wrong. If words are used in war, they are weapons in disguise, not meaningful communications. 

This transformation from dialogue to war changes morality itself. You are now judged, not by the sincerity of your pursuit of truth, but by how loyal you are to your tribe. Even to take seriously the opposing position is viewed like reading a propaganda flyer dropped from a Nazi airplane: don’t even read it, it will only twist your mind! 

Even seven years ago, fans of Jordan Peterson were fond of the phrase “all I want is to have a reasoned debate.” Regardless of your opinion of Peterson or of whether he exemplified this, those who used this phrase revealed a desire for dialogue rather than war. But today, many of those same followers no longer say that. Now they say, “the left is out to get us and must be stopped” and their counterparts say, “the right is out to get us and must be stopped.” Reasoned debate is seen as no longer effective in light of the vile underhanded tactics of the other side (but not, of course, of my side).

What do we want from our political opponents? We want them to listen to us and to take our arguments seriously. 

What role can Christianity have in this polarised society? Sadly Christians are often seen as part of the problem rather than the solution: sold out to one political party. But we should be clear that Christianity does not sit neatly on either side of the divide. That does not mean Christians should be moderate or “centrist,” as if none of the issues matter much. Christianity comes down strongly on many things, but those are spread across the political spectrum. The way Christians vote depends on which issues they judge to be the most important or pressing in the current circumstances. 

Second, Christians are called to make peace in time of war. “Blessed are the peacemakers,” Jesus said, “for they will be called children of God.” Christians are called build bridges rather than burn them, to seek common ground rather than trying to obliterate their opponents. This can start with showing love and respect for the person behind the argument; by celebrating our common humanity before trying to argue a point. 

Third, it means exemplifying the kind of attitude we want to see in our opponents. “In everything do to others as you would have them do to you,” Jesus told his disciples. What do we want from our political opponents? We want them to listen to us and to take our arguments seriously. We want them to stop making cheap caricatures of us and represent us at our best. We want them to break out of their echo chambers and read news from a variety of political leanings. We want them to open themselves to persuasion and be prepared to change their minds. Jesus suggests leading by example and doing those things first.  

Fourth and finally, the Christian’s allegiance is to truth and justice above any tribe, any agenda. The real political situation is almost certainly complex, with much to be said for and against both sides. There are awkward facts that don’t fit our own political position; let’s admit them. The Christian commitment to truth means being ready to acknowledge the weaknesses, failings, and faults on our own side before we point the finger. It’s hard, I know. I am not perfect at it myself. But it’s a more Christlike moral standard to aim for than that of the culture warrior who excels at demolishing the enemy.  

Restoring dialogue won’t be easy and may come at a high personal cost. But the cost is greater if we don’t try. My own desire is to see Christians taking the lead in the restoration process and showing the world what Christlike peacemaking can accomplish.
