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.

The Advent poets who can’t wait until the world is sane

Tennyson to Eliot, Rossetti to L’Engle, find despair doesn’t preclude joy.

After his conversion to Anglo-Catholicism in 1927, critics began to notice a change in T. S. Eliot’s poetry. Some thought this was for the worse, that Eliot’s newfound faith dimmed his literary powers, making his usually impenetrable style more conventional. But there is a less cynical view. I think, instead, that his conversion brought a sense of clarity and purpose to his poetry. I think what really happened is that, like many Christian converts before and after him, he found a sense of joy.

Nowhere better can we find that distinctly Christian sense of joy than in Eliot’s ‘The Journey of the Magi’, an Advent poem recounting Jesus’s birth from the point of view of the magi travelling to meet him. Like many of my favourite Advent poems, ‘Journey of the Magi’ is not straightforwardly cheerful, instead dwelling on the idea of alienation. The last stanza of the poem in particular is devoted to the magi’s confusion at returning to their old life after witnessing the miracle of Christ’s birth:

All this was a long time ago, I remember,
And I would do it again, but set down
This set down
This: were we led all that way for
Birth or Death? There was a birth, certainly,
We had evidence and no doubt. I had seen birth and death,
But had thought they were different; this Birth was
Hard and bitter agony for us, like Death, our death.
We returned to our places, these Kingdoms,
But no longer at ease here, in the old dispensation,
With an alien people clutching their gods.
I should be glad of another death.

It’s hard not to read these lines and imagine that Eliot himself might have experienced a feeling of alienation, as a new convert, when looking back on his old life. And yet, the magi’s sense of being ‘no longer at ease’ in their old home, of being among ‘an alien people’, is not something that only converts experience. All of us, whether we are converts or reverts, whether we were brought up in the Christian faith or are still contemplating it with uncertainty, have a moment when we realise that believing in Christ’s birth, death, and resurrection radically changes the way we look at the world.

And conversion isn’t something that just happens once. Every year, during Advent, we are asked to meet despair with joy. For those of us living in the northern hemisphere, we’re specifically asked to do this in the darkest and coldest time of the year, when nature looks so gloomy and unwelcoming. As Christina Rossetti puts it in one of our country’s most beloved Christmas hymns, Jesus comes not at a time of flourishing nature, but rather ‘in the bleak midwinter’, when the earth is ‘hard as iron’ and water frozen ‘like a stone’. Just as we persevere in our yearly hope that spring will come again, so too we are called to renew our conversion of heart each Advent, waiting in hope for Christ’s birth.

But hope doesn’t have to mean blind optimism. The older I’ve become, the more I’ve come to think that rejoicing during Advent doesn’t have to involve unadulterated cheerfulness. Grief has its place within joy, as counterintuitive as that may seem. In fact, Advent is an opportunity to cultivate the virtue of hope in spite of grief, and in spite of the evils that we see in the world. ‘Were we led all that way for / Birth or Death?’, ask the magi. The answer is both. Each year Christ’s birth reminds us that faith requires us to die to our old selves. For some, this means having uncomfortable conversations with family or friends who don’t understand their conversion to the faith. For others, it means facing illness or death of a loved one or other kinds of trauma without giving in to despair.

None of this is easy, of course. Clinging to hope in dark times can truly feel like ‘bitter agony’, as Eliot writes. And yet, as one of the magi says in the final line of Eliot’s poem, ‘I should be glad of another death’. When we die to our selves, we also experience a new birth in Christ. Even as we celebrate his birth, we are reminded of his death on the cross for us, of the fact that he so loved us that he was willing to bear unbearable pain for our sake.

That kind of love, although it doesn’t remove all the sources of suffering in our daily life, does call for rejoicing. Another wonderful Advent poem, Madeleine L’Engle’s ‘First Coming’, emphasises the necessity of joyfulness in the face of a corrupted world. L’Engle begins by reminding us, stanza after stanza, that Jesus didn’t wait for humanity to become perfect before coming to us: ‘He did not wait till the world was ready’, she begins, before adding, ‘He did not wait for the perfect time’, ‘He did not wait till hearts were pure’. Rather, Christ came ‘in joy’, to ‘a tarnished world of sin and doubt’, right ‘when the need was deep and great’.

L’Engle ends ‘First Coming’ by encouraging us to imitate Christ not just in his patience, but also in accepting joy now, not when we world finally stops being rife with sin and pain:

We cannot wait till the world is sane
to raise our songs with joyful voice,
for to share our grief, to touch our pain,
He came with Love: Rejoice! Rejoice!

We can’t wait until ‘the world is sane’ to be joyful. Joy is remembering that Christ really did come ‘to share our grief’, no matter how seemingly unbearable it may be. Lord Tennyson expresses a similar sentiment in his poem In Memoriam, an elegy written after the loss of his dear friend Arthur Hallam. He admits that the pain at his friend’s death is so intense that, as Christmas is drawing near, he almost wishes ‘no more to wake’, and for his ‘hold on life’ to ‘break’. Then, he hears the sounds of bells:

But they my troubled spirit rule,
For they controll'd me when a boy;
They bring me sorrow touch’d with joy,
The merry merry bells of Yule.

Happy memories of Christmas bells from childhood are mixed with pain for Tennyson, bringing him ‘sorrow touch’d with joy’. That’s what all the best Advent poems, from Tennyson to Eliot, From Rossetti to L’Engle, show us: that sorrow doesn’t preclude joy. In the weeks leading up to Christ’s birth, it’s normal to dwell on both birth and death; Advent can be a season for both somberness and merrymaking. Most of all, Advent is a time for prayer, that our hearts may be filled with the knowledge that Christ loves us even in our sorrow, and that the very knowledge of Christ’s love may in turn fill our hearts with joy.
