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.

“Shortening death” sidesteps the real battle

We need to do more than protest bad deaths, we need to protest death itself, it's more than biological.

What is “death”? It’s surprising the term has received little attention in the assisted dying discussion so far, because more hangs on the answer than one might expect. At a press briefing, Kim Leadbeater MP stated that the assisted dying bill she is proposing is about “shortening death, not ending life.” 

But what meaning does “death” have here? 

The current bill defines neither “death” nor “dying.” Granted, it implies a biological definition. The bill speaks of administering approved substances to “cause that person’s death” and of capacity and decision-making around “ending life.” These fit the understanding of death with which the medical profession operates—death is the point in time when the combined functions required for human life cease. It is a one-time event, the end of physiology, and so is recognised by a combination of physical signs.  

Death, then, is a diagnosis. 

So, too, “dying”—though here the waters are murkier. Setting aside sudden deaths, medical talk of dying takes us out of binary territory. Dying speaks of a process, of the “terminal phase.” Within medicine a diagnosis of dying heralds the expectation that a person’s death will occur within hours or days. And so, the focus shifts. The task of care is no longer the coordinated work of investigation, preserving life, and treating symptoms. Now attention is on bringing relief to the process of dying. 

The bill seems wise to much of this. Though definitions of death and dying are absent, the bill does define terminal illness—“an inevitably progressive condition which cannot be reversed by treatment” and from which the event of death “can reasonably be expected within 6 months.” And so, it clearly distinguishes terminal illness from biological death and, implicitly, from dying. 

Of course, terminal illness and biological death are related. Terminal illness is irreversible, and where terminal illness leads is death. Or, you might say, it leads to the end of life. Apart from the timescale of six months, the same may be said of ageing: ageing is irreversible, and where ageing leads is death. This is why Kim Leadbeater’s comment was puzzling to me. I suspect what she really meant was “shortening terminal illness.” If so, this is confusing because, within the framework of the bill, “shortening terminal illness” and “ending life” are identical. It seems she was getting at something else.

“It seems odd that in the name of eliminating suffering, we eliminate the sufferer.” 

Stanley Hauerwas

I suspect Kim Leadbeater was echoing a conviction at home in the Christian faith. That is, try as we might to keep death at a distance and restrict it to a faraway frontier, the life of human beings involves death. I don’t simply mean the biological death we witness—the deaths of friends, relatives, or even strangers. I mean death intrudes upon the way we experience life. Death is more than simply biological. 

The fear of death belongs in this category. For some, the impending loss of relationships and joys casts a shadow over life, giving birth to apprehension. Death is not simply a factual matter but something that exerts power and influence. Or take disease and illness. Built into the notion of terminal illness is the idea that the sickness borne by a human body will ultimately bring about that body’s death. That body already speaks of its death. Death is making itself felt in advance. 

And so, death is more than a biological event. Even living things can bear the marks of death. 

This is no novel claim. The creation account recorded in the Bible says that in the beginning, there was good. But an intruder appears. In the wake of humanity’s choice to go its own way rather than the way of its Maker, death arrives on the scene. And death is an imposter—not simply a physiological fact at the end of the road, but a destructive and alien presence in God’s good world. 

Understood in this way, death is not something that God intends humans simply submit to. Death is something to protest. This is why Kim Leadbeater’s comment gets at something important: this kind of death should be protested. The marks of death should not be accommodated, because they do not belong to the goodness of what God has made. 

At the heart of the Christian faith is God’s own ultimate protest against the force of death. Christians celebrate that God himself came in the man Jesus to “destroy death.” This is plainly more than biological. Jesus came to free humanity from the entirety of death’s grip. Hence why, when Jesus speaks of “eternal life” he means more than endless biological existence. He means liberation from all the havoc that death brings to bear within God’s world. To the Christian imagination, the power of death must be protested because God protested it first. 

The question is how to protest death. Within the framework of the bill, shortening death or terminal illness is identical with ending life. This is the only form protesting death can take. 

But the Christian faith makes a far more radical claim: God alone overcame death by dying. This is the point: Jesus was the one—the only one—who emerged resurrected victor in the contest with the power of death. In seeing his death and resurrection, an unshakeable hope emerges. Death is not the victor. And this hope stands above our present experience of death—in whatever form—and, at the same time, calls us to join the protest. 

Ethicist Stanley Hauerwas once wrote: “it seems odd that in the name of eliminating suffering, we eliminate the sufferer.” I have deliberately avoided discussing suffering, not least because it would take me too far afield. Yet Hauerwas has put his finger on what I’m getting at. Protesting death—in the big sense—belongs to the Christian faith. Protesting suffering and pain, economic and racial injustice, fractured relationships and broken societies, are all part of this protest. But can eliminating those who live within the shadow of death be part of this protest? I think not. The Christian faith believes there is only one who can overcome death in this way, and that is God himself—who has already done it.
