The radical uniqueness of the Christmas story can be easily lost in a culture over-familiar with carols, nativity scenes, and Christmas cards. The birth of Jesus is not, for Christians, merely the birth of the founder of their religion, comparable to Muhammad, the Buddha, Guru Nanak, or Moses. The heart of the Christian claim is that in the Incarnation, the Almighty Creator of all things has irrevocably identified himself with the human race, standing in solidarity with every person who ever existed and ever will exist.

Imagine Tolkien being born as a hobbit in the Shire, or J.K. Rowling going to school at Hogwarts. The mind-bending notion of the author entering his or her own creation is far closer to the Christian idea of Jesus than any comparison between him and other great figures of history. For Christians, he was not just a moral teacher, not just an inspiring example – not even an object of adoration and love without further qualification. He was and is all these things of course. But all those things are put in the shade by something else, totally unique and unrepeatable: Immanuel, God-among-us.

The implications of this are staggering. Dorothy Sayers puts it this way (quote slightly adapted):

For whatever reason God chose to make human beings as we are – limited and suffering and subject to sorrows and death – he had the honesty and the courage to take his own medicine. Whatever game he is playing with his creation, he has kept his own rules and played fair. He can exact nothing from us that he has not exacted from himself. He has himself gone through the whole of human experience, from the trivial irritations of family life and the cramping restrictions of hard work and lack of money to the worst horrors of pain and humiliation, defeat, despair, and death. He was born in poverty and died in disgrace and thought it well worthwhile.

The Christian God is a God who plays fair, who keeps the rules he commands us to keep, who suffered the same pain, anxiety, and daily struggle that we all suffer in the world he created.

How is this possible? Only if we hold together two things that look like a contradiction at first sight: that Jesus is both fully God and fully human, at the same time, without confusion or separation. This is how Christian dogma has been enshrined in our creeds.

The early centuries of Christianity were a delicate balancing act. Theory after theory was tried and abandoned because it failed to hold the necessary tension between ‘fully God’ and ‘fully man’. The long councils with hundreds of bishops arguing over the precise wording of the creed may seem very remote to our daily concerns, but they were trying to protect something vital to the life of the Church. One word wrong could have upset the whole balance, and Christianity would have become simply another mystical apparition or set of moral guidelines along hundreds of others in the ancient world.

If we let go of the ‘fully God’ part, then we are left with a religious teacher who may inspire devotion, offer moral guidance, or even speak with the voice of God. But we do not have the Creator himself entering his creation to experience it as we do.

If we let go of the ‘fully human’ part, then we are left with a supernatural appearance of the one who made us. He might command us to live a certain way and punish us when we fail. He might leave detailed instructions about the right way to worship him. But he did not share our condition. He did not get sunburnt, jostled in the street, woken up, pinched, teased at school, or sold a dud.

The magic is in that combination of the two, almost impossible to grasp, that puts the source of all power, truth and beauty in a collision course with the deepest fears, sufferings, joys, hopes and longings of every member of the human race. The one who made us is not unaware of what it is like to live in this world. Whatever his mysterious purposes may be for his creation, they involve humanity in a prominent position. And whatever God destines for our race is a destiny he shares. As G.K. Chesterton writes of the Incarnation:

‘Since that day it has never been quite enough to say that God is in his heaven and all is right with the world, since the rumour that God had left his heavens to set it right.’

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.
