It's our mistakes that make us human

What we learn distinguishes us from tech.

The distinction between technology and human beings has become blurry: AI seems to be able to listen, answer our questions, even respond to our feelings. It becomes increasingly easy to confuse machines with humans. In this situation, it is increasingly important to ask: What makes us human, in distinction from machines? There are many answers to this question, but for now I would like to focus on just one aspect of what I think is distinctively human: As human beings, we live and learn in time.

To be human means to be intrinsically temporal. We live in time and are oriented towards a future good. We are learning animals, and our learning is bound up with the taking of time. When we learn to know or to do something, we necessarily make mistakes, and we take practice. But keeping in view something we desire – a future good – we keep going.

Let’s take the example of language. We acquire language in community over time. Toddlers make all sorts of hilarious mistakes when they first try to talk, and it takes them a long time even to get single words right, let alone to try and form sentences. But they keep trying, and they eventually learn. The same goes with love: Knowing how to love our family or our neighbours near and far is not something we are good at instantly. It is not the sort of learning where you absorb a piece of information and then you ‘get’ it. No, we learn it over time, we imitate others, we practice and even when we have learned, in the abstract, what it is to be loving, we keep getting it wrong.

This, too, is part of what it means to be human: to make mistakes. Not the sort of mistakes machines make, when they classify some information wrongly, for instance, but the very human mistake of falling short of your own ideal. Of striving towards something you desire – happiness, in the broadest of terms – and yet falling short, in your actions, of that very goal. But there’s another very human thing right here: Human beings can also change. They – we – can have a change of heart, be transformed, and at some point in time, actually start to do the right thing – even against all the odds. Statistics of past behaviours, do not always correctly predict future outcomes. Part of being human means that we can be transformed.

Transformation sometimes comes suddenly, when an overwhelming, awe-inspiring experience changes somebody’s life as by a bolt of lightning. Much more commonly, though, such transformation takes time. Through taking up small practices, we can form new habits, gradually acquire virtue, and do the right thing more often than not. This is so human: We are anything but perfect. As Christians would say: We have a tendency to entangle ourselves in the mess of sin and guilt. But we also bear the image of the Holy One who made us, and by the grace and favour of that One, we are not forever stuck in the mess. We are redeemed: are given the strength to keep trying, despite the mistakes we make, and given the grace to acquire virtue and become better people over time. All of this to say that being human means to live in time, and to learn in time.

So, this is a real difference between human beings and machines: Human beings can, and do strive toward a future good.

Now compare this to the most complex of machines. We say that AI is able to “learn”. But what does it mean to learn, for AI? Machine learning is usually categorized into supervised learning, unsupervised and self-supervised learning. Supervised learning means that a model is trained for a specific task based on correctly labelled data. For instance, if a model is to predict whether a mammogram image contains a cancerous tumour, it is given many example images which are correctly classed as ‘contains cancer’ or ‘does not contain cancer’. That way, it is “taught” to recognise cancer in unlabelled mammograms. Unsupervised learning is different. Here, the system looks for patterns in the dataset it is given. It clusters and groups data without relying on predefined labels. Self-supervised learning uses both methods: Here, the system uses parts of the data itself as a kind of label – such as, for instance, predicting the upper half of an image from its lower half, or the next word in a given text. This is the predominant paradigm for how contemporary large-scale AI models “learn”.

In each case, AI’s learning is necessarily based on data sets. Learning happens with reference to pre-given data, and in that sense with reference to the past. It may look like such models can consider the future, and have future goals, but only insofar as they have picked up patterns in past data, which they use to predict future patterns – as if the future was nothing but a repetition of the past.

So this is a real difference between human beings and machines: Human beings can, and do strive toward a future good. Machines, by contrast, are always oriented towards the past of the data that was fed to them. Human beings are intrinsically temporal beings, whereas machines are defined by temporality only in a very limited sense: it takes time to upload data, and for the data to be processed, for instance. Time, for machines, is nothing but an extension of the past, whereas for human beings, it is an invitation to and the possibility for being transformed for the sake of a future good. We, human beings, are intrinsically temporal, living in time towards a future good – which machines do not.

In the face of new technologies we need a sharpened sense for the strange and awe-inspiring species that is the human race, and cultivate a new sense of wonder about humanity itself.

After the fall: the Post Office scandal and the search for justice

Falls from grace, like that of the Post Office’s CEO, prompt Graham Tomlin to dissect the problems of justice and mercy.

It was November, and I was in Rome. With the new year on the horizon, newsagents were displaying calendars for 2024. One in particular seemed to show up in just about every street vendor available: the ‘Hot Priest Calendar’.

It had pictures for every month of young, bronzed, good-looking priests, resplendent in brand new, ironed black clerical shirts, smouldering into the camera. I've no idea whether they were real priests or just models in clerical garb. I didn't buy one, but it did get me thinking of why they had produced it. Was this a recruitment drive for clergy in the Roman Catholic Church? Something for the nuns to put on the wall of the convent? It was hardly aiming to attract women by saying if you become a Catholic you could bag one of these hunky chaps, as priests are, well, supposed to be out of reach.

I suspect it was just trying to tell the world that the Church is cool after all. That the church is for good-looking, shiny people, not just the regular ones with wrinkles and expanding waistlines.

The embarrassment and shame are real and proper and yet there is, in my view, something at the heart of it which seems to be mistaken.

I was thinking of this recently while watching the story of the Post Office scandal unfold. This dreadful story is, to be frank, a bit of an embarrassment for the Church of England. This horrendous miscarriage of justice has its heart not just a Christian but a priest. I met Paula Vennells once. While I was Bishop of Kensington, we planned a big conference for all the vicars in the Diocese of London. At the time, Vennells’ star was rising in ecclesiastical circles. People had just noticed that the head of the Post Office not only went to church, but was also ordained, and so she was getting invited to speak at all kinds of conferences. She agreed to come and, to be fair, was gracious, unassuming, polite. There was nothing to suggest she was soon to become the object of public opprobrium that she is now.

She would definitely not go on a Church Calendar these days. But then who would? The last decade has seen a succession of scandals and falls from grace – Harvey Epstein, Huw Edwards, Russell Brand, Philip Schofield - and Christian leaders are not exempt. Jean Vanier, Ravi Zacharias, Mike Pilavachi – the list goes on – and now Paula Vennells. We Christians hang our heads, as it seems such a deep failure - how can someone profess to be a Christian – even a vicar - and yet do such things? The embarrassment and shame are real and proper and yet there is, in my view, something at the heart of it which seems to be mistaken.

Celebrities are celebrated because we believe they are different from us ordinary mortals. But sooner or later, it turns out they have the same temptations, their bodies sag, their flaws get exposed.

Helmut Thielicke was a German theologian who opposed the Nazis during the Second World War and somehow survived. His was a crucial voice in the German church and nation as it struggled to its feet again after the trauma and destruction of those years. The big question Germany faced at the time was how a modern sophisticated Christian nation had been so easily seduced by evil? They also struggled with the question of shame. What were German Christians to do with the guilt that hung over them after the Nazi years?

Thielicke was a brilliant preacher and drew huge crowds to his church in Hamburg. In one of his sermons he took as his text St Paul’s line, that Christians are “a letter from Christ, written not with ink but with the Spirit of the living God, on tablets of human hearts.” He asked his congregation the question: what kind of letter are you? Is a Christian meant to be an advert for God? Is the Christian a shiny product of divine handiwork so that God, like some marketing agent, says ‘Look at her – isn’t she is fine person? Wouldn’t you like to be like her?’

When she was being feted by all, we might have said that about Paula Vennells. But not any more. And that’s the problem of celebrity Christians, or celebrities of any kind for that matter. They are used as adverts for the brand they profess, religious or otherwise: “Use this shampoo, follow this diet, believe this religion, like this celebrity does, and you could be like them.”

Celebrities are celebrated because we believe they are different from us ordinary mortals. But sooner or later, it turns out they have the same temptations, their bodies sag, their flaws tend to get exposed in the extra scrutiny they face in a gossipy age like ours. The hunky priests in the calendar may look good but I suspect their lives are as shadowy and compromised as the rest of us. Every now and again you find a life that is remarkable, but even then there are dark corners. Mother Teresa famously said that she rarely experienced the presence of God and struggled with lifelong depression. If we are meant to be adverts for God, we’re not very good ones.

Thielicke’s point was that Christians are not meant to be adverts for God but letters from him. And the letter, written on the human heart, says something like this: “Here is a poor, weak human being with their own strengths and frailties, moments of courage and moments of great weakness, struggling to live a good life but failing much of the time. And yet, despite that failure, God still forgives, accepts, loves and stands by them.”

And forgiveness is not an excuse. It doesn’t say ‘it didn’t happen’, but it says, ‘it did happen’ and it was bad, but a new start is always possible.

It sounds scandalous I know. Hearing about the Post Office scandal, all we want is for the perpetrators to be found guilty and punished. And rightly so. Justice must be done. Paula Vennells and her staff seems to have stuck stubbornly to the laughable view that the Post Office had been infiltrated by hundreds of criminal sub-postmasters, intend on defrauding the public purse. They lacked the sense or courage to question their own IT system, despite being warned it was faulty.

Yet divine and human justice work in different ways. Not least because God, unlike human judges, sees the dodgy things we all do, not just those whose sins get found out because they are in the public eye. Human justice systems must take their course, crimes must be punished, and attempts made to turn around the lives of those caught in patterns of criminality. Yet underneath human justice lies divine justice, which promises an ultimate judgment, even for those who escape human justice. Yet at the same time, it offers not just justice, but mercy - the gift of a more profound and ultimate forgiveness, which, if accepted, does not override the penalties of human justice, but enables the possibility of redemption in the longer term.

Martin Luther often used a Latin phrase to describe Christians – that they are simul iustus et peccator - ‘at the same time righteous and sinful’. Like an alcoholic who is never encouraged to say that were an alcoholic, but that they are a recovering one, an honest Christian doesn’t say ‘I was a chronic worrier, greedy, someone who struggles with lust,’ but ‘I am such things, and yet faith in Jesus makes a difference in helping me not to be.’ St Paul once said: ‘Christ Jesus came into the world to save sinners – of whom I am the worst.’ Not I was the worst, but I am. I remember Frank Bruno once saying “I’m not much of a Christian – I’ve been a sinner all my life.” He hadn’t quite understood - Christians are only ever recovering sinners.

Paula Vennells and the others responsible for the Post Office scandal will have to face justice one day. It may, for some, even mean prison. But, as many in our prisons up and down the country know, lots of people find God in prison - not as a literal ‘get out of jail free card’ – the justice system doesn’t play Monopoly – but a realisation that however bad your crimes, however murky our misdemeanours or sly our sins, forgiveness is possible. And forgiveness is not an excuse. It doesn’t say ‘it didn’t happen’, but it says, ‘it did happen’ and it was bad, but a new start is always possible, and the love and forgiveness of God is available, even for the worst of people - for good-looking priests who struggle with temptation, for celebrities who fall from grace. Or even ordinary people like us.
