AI will never codify the unruly instructions that make us human

The many exceptions to the rules are what make us human.

On average, students with surnames beginning in the letters A-E get higher grades than those who come later in the alphabet. Good looking people get more favourable divorce settlements through the courts, and higher payouts for damages. Tall people are more likely to get promoted than their shorter colleagues, and judges give out harsher sentences just before lunch. It is clear that human judgement is problematically biased – sometimes with significant consequences. 

But imagine you were on the receiving end of such treatment, and wanted to appeal your overly harsh sentence, your unfair court settlement or your punitive essay grade: is Artificial Intelligence the answer? Is AI intelligent enough to review the evidence, consider the rules, ignore human vagaries, and issue an impartial, more sophisticated outcome?  

In many cases, the short answer is yes. Conveniently, AI can review 50 CVs, conduct 50 “chatbot” style interviews, and identify which candidates best fit the criteria for promotion. But is the short and convenient answer always what we want? In their recent publication, As If Human: Ethics and Artificial Intelligence, Nigel Shadbolt and Roger Hampson discuss research which shows that, if wrongly condemned to be shot by a military court but given one last appeal, most people would prefer to appeal in person to a human judge than have the facts of their case reviewed by an AI computer. Likewise, terminally ill patients indicate a preference for doctor’s opinions over computer calculations on when to withdraw life sustaining treatment, even though a computer has a higher predictive power to judge when someone’s life might be coming to an end. This preference may seem counterintuitive, but apparently the cold impartiality—and at times, the impenetrability—of machine logic might work for promotions, but fails to satisfy the desire for human dignity when it comes to matters of life and death.  

In addition, Shadbolt and Hampson make the point that AI is actually much less intelligent than many of us tend to think. An AI machine can be instructed to apply certain rules to decision making and can apply those rules even in quite complex situations, but the determination of those rules can only happen in one of two ways: either the rules must be invented or predetermined by whoever programmes the machine, or the rules must be observable to a “Large Language Model” AI when it scrapes the internet to observe common and typical aspects of human behaviour.  

The former option, deciding the rules in advance, is by no means straightforward. Humans abide by a complex web of intersecting ethical codes, often slipping seamlessly between utilitarianism (what achieves the most amount of good for the most amount of people?) virtue ethics (what makes me a good person?) and theological or deontological ideas (what does God or wider society expect me to do?) This complexity, as Shadbolt and Hampson observe, means that: 

“Contemporary intellectual discourse has not even the beginnings of an agreed universal basis for notions of good and evil, or right and wrong.”  

The solution might be option two – to ask AI to do a data scrape of human behaviour and use its superior processing power to determine if there actually is some sort of universal basis to our ethical codes, perhaps one that humanity hasn’t noticed yet. For example, you might instruct a large language model AI to find 1,000,000 instances of a particular pro-social act, such as generous giving, and from that to determine a universal set of rules for what counts as generosity. This is an experiment that has not yet been done, probably because it is unlikely to yield satisfactory results. After all, what is real generosity? Isn’t the truly generous person one who makes a generous gesture even when it is not socially appropriate to do so? The rule of real generosity is that it breaks the rules.  

Generosity is not the only human virtue which defies being codified – mercy falls at exactly the same hurdle. AI can never learn to be merciful, because showing mercy involves breaking a rule without having a different rule or sufficient cause to tell it to do so. Stealing is wrong, this is a rule we almost all learn from childhood. But in the famous opening to Les Misérables, Jean Valjean, a destitute convict, steals some silverware from Bishop Myriel who has provided him with hospitality. Valjean is soon caught by the police and faces a lifetime of imprisonment and forced labour for his crime. Yet the Bishop shows him mercy, falsely informing the police that the silverware was a gift and even adding two further candlesticks to the swag. Stealing is, objectively, still wrong, but the rule is temporarily suspended, or superseded, by the bishop’s wholly unruly act of mercy.   

Teaching his followers one day, Jesus stunned the crowd with a catalogue of unruly instructions. He said, “Give to everyone who asks of you,” and “Love your enemies” and “Do good to those who hate you.” The Gospel writers record that the crowd were amazed, astonished, even panicked! These were rules that challenged many assumptions about the “right” way to live – many of the social and religious “rules” of the day. And Jesus modelled this unruly way of life too – actively healing people on the designated day of rest, dining with social outcasts and having contact with those who had “unclean” illnesses such as leprosy. Overall, the message of Jesus was loud and clear, people matter more than rules.  

AI will never understand this, because to an AI people don’t actually exist, only rules exist. Rules can be programmed in manually or extracted from a data scrape, and one rule can be superseded by another rule, but beyond that a rule can never just be illogically or irrationally broken by a machine. Put more simply, AI can show us in a simplistic way what fairness ought to look like and can protect a judge from being punitive just because they are a bit hungry. There are many positive applications to the use of AI in overcoming humanity’s unconscious and illogical biases. But at the end of the day, only a human can look Jean Valjean in the eye and say, “Here, take these candlesticks too.”

You may never take the Salt Path but here's why the tale makes sense

Kindness runs deep in the architecture of reality.

Roger is a Baptist minister, author and Senior Research Fellow at Spurgeon’s College in London.

The Salt Path is a phenomenon.  

An internationally best-selling book and now a movie starring Gillian Anderson and Jason Isaacs. How is it that a memoir of a middle-aged couple walking the South West Coast Path from Somerset to Dorset, via Land’s End, has had such an impact? 

Well, it’s because it resonates. It rings true. It’s about life as we know it, even if we haven’t hiked the 630 miles of the path from start to finish. A journey that is also, incidentally, the equivalent of climbing Mt Everest four times over. 

In the events leading up to their walk Raynor (Ray) and Moth Winn are dealt a series of body blows. They’re left bankrupt and homeless empty-nesters, struggling to come to terms with Moth’s deteriorating health.  

It was just as the bailiffs were seeking to gain access to their farm and take possession of it that Ray spotted an old book, 500 Hundred Mile Walkies, and took inspiration. 

‘We could just walk.’ 

And that’s what they did. 

So, what are the truths about life and our human experience that this story opens up for us? 

Life is precarious  

Bad stuff happens. Sometimes we bring it on ourselves, the consequence of wrong or ill-judged decisions. Other times it is thoroughly undeserved. Life turns around and bites us, hard. We’re left with our heads numb and spinning round with the persistent but unanswered question, ‘why me?’ 

For the Winns, an investment in the business of a trusted, life-long friend failed. The deal he structured left them responsible for the debts of his company. The end of a prolonged legal battle meant they lost everything, their farm, their home, their business, and the life-long friend. 

The same week also found them in a hospital in Liverpool getting the diagnosis for Moth’s chronic shoulder pain. It was not the suspected nerve damage, but rather the fatal neurological condition corticobasal degeneration. CBD. A diagnosis that was untreatable and only finally confirmed postmortem. 

Whether it’s the South West Coast Path or the familiar details of our own life, we can never fully anticipate tomorrow. We do not know what lies behind the next headland or what unwelcome surprises life may spring on us. No, we need to live in the moment. It’s pointless worrying about tomorrow and we ought to let it worry about itself. We can only live in today. As Ray reflected towards the end of their time on the path: 

“This second in the millions of seconds was the only one, the only one that we could live in.” 

Who am I, really? 

Early in the book Ray recalls: 

“I once heard a lecture by Stephen Hawking, when he said, ‘It’s the past that tells us who we are. Without it we lose our identity.’ Perhaps I was trying to lose my identity, so I could invent a new one.” 

Who are we when everything is stripped away? What defines us? Homeless and jobless, questions about where we’re from and what we do are not only awkward, they also create an existential void.  

Often mistaken for tramps, Ray and Moth noticed people treating them differently. Some quietly moved away, others were more forthright, “disgusting!” But the judgement of others does not define who we are. Yet, who actually were they in this new world of theirs?  

And then there’s the impact of failing health. Each stage of deterioration promising to erode what can be physically done and requiring a redefinition until there is nothing left at all.  

Yet identity is deeper than that. It is at the core of who we are, at the very heart of us. It is the sum of our experiences and choices, our successes and failures, of what we have gladly embraced and that which life has unexpectedly thrown at us. We are unique individuals with intrinsic value, worth and dignity. People who love and are loved. 

At the end of the path Ray muses: 

“Most people go through their whole lives without answering their own questions: What am I, who do I have within me? The big stuff. What a waste.” 

I guess that’s one of the attractions of making space to walk. To lose the distractions and busyness of our over-complicated lives for self-discovery to break in. 

One step at a time 

How do you get your head around walking 630 miles? How can you appreciate the demands of climbing unknown hills and cliffs and navigating their gullies and ravines.  

On top of the terrain there’s the notorious English weather to negotiate. With little money and only a tent for respite: when it rains you get wet and stay wet, when it’s cold, you shiver and put on as many layers as you can. Even in August it can be challenging. 

Walk, eat, sleep, repeat. 

Sometimes the only thing to do is put one foot in front of the other.  

“Each step had its own resonance, its moment of power or failure. That step, and the next and the next and the next, was the reason and the future. … each day survived a reason to live through the next.” 

There is always agency. There is always the opportunity to choose today which path to travel and which attitude to serve. To give in or go on, to be a defeatist or hopeful, complaining or generous, those choices are always there, even when they’re limited. Even in the wake of unfair decisions and unexpected tragedy, we choose today the way we take. And sometimes that’s all we can muster. 

The kindness of strangers 

Ray and Moth’s story is littered with moments of kindness and warmth. From the lovelorn waitress who sneaks them the day’s leftover pasties to the generosity of a hippie commune there is a recurring theme that echoes an underlying goodness in the nature of people. And often it is those with the least who prove to be the most open-handed and thoughtful. 

On more than one occasion the Winn’s themselves share from their own meagre supply of food, especially their precious fudge bars, with those in a more uncertain state than their own. On another occasion they step into a tense and potentially violent situation with a young woman, Sealy, the subject of an abusive relationship. They offer her company and a way out, ultimately paying for her £5 bus journey to get away to family. 

There is something heartwarming about kindness, something elevating. Both the giver and the receiver feel encouraged, lighter, happier. The abiding truth continues to stand the test of time that it is ‘better to give than to receive’.  

Strangely, watching these scenes play out in my local Showcase Cinema was an uplifting and inspiring experience. You can never predict or properly anticipate when a tear will unexpectedly present itself to the corner of your eye. I suspect that kindness runs more deeply in the nature of things than we comprehend. It is part of the deep architecture of reality.

Love and relationship in tough times 

When it comes down to it, The Salt Path is about Ray’s relationship with Moth. How they face an unimaginably difficult set of circumstances and find a way through together. This is a profoundly hopeful story. And from it we can draw hope too. 

There was nothing religious about what they were doing, “It’s not a pilgrimage. Is it?”  

At one level it is purely a response to desperation. But in the midst of it all they have each other. Thirty-two years together, having begun their relationship when Ray was 18, they are still deeply in love. They epitomise the values enshrined in the marriage vows. 

“… to have and to hold from this day forward, for better for worse, for richer for poorer, in sickness and in health, to love and to cherish, till death us do part …” 

This is not slushy sentimentality but rather love that proves itself in the face of the onslaught of ‘worse … poorer … sickness … death’. 

The conclusion of their journey led Ray to a realisation: “I was home, there was nothing left to search for, he was my home.” As the ancient poet wrote: 

“Set me as a seal upon your heart,  

as a seal upon your arm; 

for love is strong as death, 

passion fierce as the grave. 

Its flashes are flashes of fire, 

a raging flame. 

 

Many waters cannot quench love, 

neither can floods drown it. 

If one offered for love 

all the wealth of one's house, 

it would be utterly scorned.” 

(Song of Solomon) 

That’s it then. The book and the movie work because they reflect back to us the life we know, the lives we live. Yes, they’re in high relief in the choices that Ray and Moth take, but that clarifies things for us. Most of us won’t ever find ourselves in the position they were in, but we can empathise. Most of us would never think to do what they did even if we were. But for all that, we see, we understand and it makes sense. 

If you get a chance to see the film, then do. Gillian Anderson and Jeremy Isaacs are exceptionally good in their understated performances. The visual experience of the South West coast is everything you would expect it to be, sounding as majestic and immersive as if you were there. A real treat. 

For me, the most poignant and telling moment of the story happens at Lyme Regis. Moth says: 

“When it does come, the end, I want you to have me cremated. …keep me in a box somewhere, then when you die the kids can put you in, give us a shake and send us on our way … They can let us go on the coast, in the wind, and we’ll find the horizon together.”
