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.

What have Easter bunnies to do with the resurrection?

As we emerge from the Easter weekend, Graham Tomlin unpacks why Easter is more than an illustration of new life.

the first signs of Spring breaking through

Bunnies, chocolate eggs, crocuses. It’s that time of year again. The dark bleakness of winter is giving way to life and colour as the soil warms. We finally feel sun on the skin, wake up to early dawns and longer days.

Across the world, festivals celebrate the coming of Spring. The Qingming Festival is a traditional Chinese carnival, also known as Tomb-Sweeping Day, observed by ethnic Chinese people across the world as a celebration of the new season. In the festival of Holi, Hindus across the world douse each other in brightly coloured powder or water, as a celebration of burgeoning love, and a prayer for a good harvest from the new growth in the land. The turning of the year, bringing new life, seems one of the most elemental forces in the universe.

In 1890, the Scottish anthropologist James Frazer published a book that was to become famous: The Golden Bough. It was one of the first works of comparative religion in an age which was gradually becoming more knowledgeable about the religions of the world. In it, he identified a motif in many of the world’s religions: the concept of a dying-and-rising god. He saw the pattern repeated in fertility rites connected to the annual renewal of nature from the ‘death’ of winter. Gods like Osiris, Tammuz, Adonis and Attis, Dionysus - and Jesus - were examples of the same pattern.

The turning of the year, bringing new life, seems to be one of the most elemental forces in the universe.

These days, you often hear a similar version of this account. Christianity, we are told, is another form of the same story found in so many religions. Christians just took over and erased the earlier annual celebrations with their own version. Christmas was just a replacement for Yule, the ancient pagan winter festival. Easter recalls Eostre, a spring goddess from western Germanic lands, whose festival took place in April, connected to the spring equinox.

Today, we have lambs, daffodils, young rabbits and eggs. All of them emerge at this time of year and are, for us, signs of the rebirth of nature. It always seems miraculous, that from the deadness of winter, life is reborn. No wonder the ancient pagans, and religions all over the world, for that matter, found ways to celebrate new life, and to endue this season with mythical wonder.

It was tempting for James Frazer to bracket Jesus as just another of these myths of the death and rebirth of nature, the dying and rising god. Bunnies, eggs, Osiris and Jesus were all symbols, pointing to the same thing – the annually repeated miracle of new life in the Spring.

Yet this misses the point of what the early Christians said about the Resurrection. St Paul wrote: “Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep.” His point was precisely not that this event was another illustration of the annual renewal of nature, the cycle of death & rebirth. It was something new altogether. It was the once and for all breaking of the cycle, spelling the end of death and its repeated power over us. Christ breaks through the dark wall of death so that millions of other can follow him through the breach into the light beyond it.

It was not another annual temporary suspension of the inevitability of death, it was the breaking of the power of death once and for all, pointing to its final defeat one day.

The Resurrection of Jesus was the ‘firstfruits’, like the very first crocus of spring, the first apple on the tree. It was like a man breaking the four minute mile, a human being walking on the moon. A barrier had been broken that had always seemed impregnable and nothing would ever be the same again. It was the beginning of an entirely new creation that will one day come into fullness. It was not another annual temporary suspension of the inevitability of death, it was the breaking of the power of death once and for all, pointing to its final defeat one day. The endless cycle of rebirth is suddenly folded out into a linear trajectory, pointing forward to the day when all shall be made new.

CS Lewis attributed his conversion at least in part to a conversation with JRR Tolkien which persuaded him that the story of Jesus – his incarnation, descent into death and resurrection to new life - was not just another example of the ancient myth of the renewal of the world, but was the thing towards which all the myths pointed – it was, as he called it in a famous essay, ‘myth become fact’. It’s worth quoting him to get the point:

Christianity is a myth which is also a fact. The old myth of the Dying God, without ceasing to be myth, comes down from the heaven of legend and imagination to the earth of history. It happens—at a particular date, in a particular place, followed by definable historical consequences. We pass from a Balder or an Osiris, dying nobody knows when or where, to a historical Person crucified (it is all in order) under Pontius Pilate.

Of course, there will be echoes of resurrection in the other faiths of the world. Of course there will be pagan figures who look like Christ. Rabbits and eggs are to be enjoyed not frowned on as they point to the one great miracle. They are to be welcomed, not disowned. Lewis’ point is that the Resurrection is both myth and fact – myth become fact. The Resurrection doesn’t just point to the rebirth of the world. It is the rebirth of the world.

Now of course, Christians can’t prove it. They can, to be sure, point to evidence that the tomb was empty, that the profound, world-shattering effect on the disciples and even the rest of human history can only be explained by something truly extraordinary. But you can’t prove an event that by its very nature breaks the normal cycle of cause and event, death and rebirth, proof and disproof. You can only believe it and then re-build your whole view of the world around it. As theologian Lesslie Newbigin put it:

“At the heart of the Christian message was a new fact: God had acted in a way that, if believed, must henceforth determine all our ways of thinking. It could not merely fit into existing ways of understanding the world without fundamentally changing them. It provided a new arche, a new starting point for all human understanding of the world. It could not form part of any worldview except one of which it was the basis.”

So, no, we can’t prove it. But we can at least do the early Christians the justice of acknowledging what they were saying and what they weren’t.

Because this is the central Christian claim – that the Resurrection is not a metaphor for something else – for the rebirth of nature in the spring, or for the fertility of nature. In fact, it’s the other way round. The rebirth of nature is a metaphor for the Resurrection. The Resurrection of Jesus is not an illustration of something else. It is the one thing of which everything else is an illustration. In the light of the Resurrection, the renewal of nature in spring is not yet another round in the endlessly repeated cycle of death, rebirth and death again, but it points forward to the day when “the trumpet will sound, the dead will be raised imperishable, and we will all be changed.”
