Thanks to the BBC radio show In Our Time, I’ve found a new pleasure in life. It is this: to learn about the enormity of outer space, and the absurdity of what goes on there, and to share what I find with anyone who’s interested. By ‘anyone’, I mean my wife. But now that Seen & Unseen have published this, I mean you too.

Or that mysterious cosmic rays from deep space regularly sail straight through the bodies of each of us, and scientists are baffled as to what might have created them? Did you know that a tiny, pale area of the night sky once named the ‘little smudge’, is now known to be the biggest thing anyone will ever see with the naked eye: the Andromeda galaxy? And did you know that the strength of gravity on Venus would crush you instantly? I could go on indefinitely.

The centrepiece of all this galactic trivia, however, is reserved for black holes. Almost everything about them fascinates, baffles and scares me.

Black holes are the remnants of dead stars that have collapsed in on themselves, creating a gravitational field so powerful that nothing – not even light – can escape. If you were to pass over its threshold, you’d be obliterated as you get pulled towards the black hole’s infinitely dense centre.

They get even stranger though. Inside them, astrophysicists say, the laws of physics break down completely. Time and space somehow swap places, they say. And even though anything pulled in by a black hole's gravity is crushed by unimaginable force, in some sense it may be preserved and – in theory – might end up elsewhere, in a new form. It is a death that might not in fact be the end of us.

There are many black holes – there’s one at the centre of our galaxy. But even though we can study them and develop scientific theories about them, we have not come close to grasping them in all their terrifying and monumental glory. What goes on inside them is, and perhaps always will be, an unfathomable mystery.

This is why I’d love to see them refracted through the eyes and hearts of poets and artists, philosophers and theologians. What might their strangeness tell us about their creation, their creator? What might they tell us about how to live our lives? And if gravity at its most intense can upturn the laws of science, bamboozle great minds, and maybe even turn death into new life, then might other forces of attraction that do not adhere to known laws of physics, like love, do the same?

Scenes from the Passion of Christ by Hans Memling.

In dwelling on questions like these, I have found this painting to be strangely helpful. It tells a love story that – in terms of its sheer intensity, its pull upon us, its utter strangeness, its death-defying endpoint – is not a bad match for a black hole. It’s called Scenes From The Passion Of Christ, it’s by the northern European painter Hans Memling, and when I first saw it I thought it looked silly.

Why cram onto one small canvas over twenty scenes from the final eight days of Jesus’s life on Earth? It’s like a cartoon strip without the white lines to divide up each scene. We see Jesus welcomed by a crowd, betrayed by Judas, denied by Peter, sentenced by Pilate, stripped by henchmen, humiliated by another crowd, crucified by soldiers, and buried by loved ones. We see him upending a table, praying for an escape route, sharing bread and wine, carrying a cross, emerging from the grave, and appearing to his followers.

It reduces the crucifixion to a few square millimetres at the top. It sidelines the heart of Jesus’ story – the resurrection – to the far right edge. It shrinks Jerusalem to a tiny labyrinth resembling an MC Escher painting. It is daytime and nighttime. It is disorientating. And it is claustrophobic. But I think it is also brilliant, and it’s made me look in a new way at the strangest of weeks in the story of the world.

By showing us so much convening at this moment in space and time, we sense how impossible it would have been for Jesus’s followers to compute anything that went on during that week. As each event unfolded, they would have had to rethink what might come next, whilst dealing with some pretty overwhelming emotions. They would have had no time or space to process any of it. It seems perfect, therefore, that in this painting, we don’t either.

But as I look at it now, I wonder: have we actually processed these events, two thousand years later? Do Christianity’s attempts to explain everything that went on here really do justice to a story in which divine love does some of the unfathomably strange things that a black hole does? Or do these explanations tell us more about our own way of thinking than they do God’s?

I think there is a tendency – which I see in myself and in most churches I have attended – to resist the weird, mysterious and inexplicable nature of this story. We draw heavily on logic and evidence to try and explain a story that defies both. But just as it is within the boundaries of a black hole, so it is within the frame of this painting: the old rules no longer apply. Divine love manifests itself in ways we cannot yet fathom. Pretending otherwise saps power from the story.

At the top right corner of the painting, there is a tiny dot on the seashore. It’s the last image of Jesus in this painting. And next to it, a church. Here, the baton is being handed over from Jesus to those who follow him. The church is now the ‘body of Christ’, tasked with embodying infinite love in a world that badly needs it.

What a daunting task. Frankly, it can be easier to believe in a bizarre series of events from two millennia ago, than in a church here and now, comprised of people as flawed as I am, that is meant to be capable of embodying a world-changing love.

And that is why I am so drawn to black holes, and to this painting. In them, I see that impossible things can and do happen; that unfathomable mysteries are littered throughout reality; that these mysteries are not so much problems to solve as they are wonders to revel in; that the narrow, rational mindset in which I too often dwell is small and limiting; and that an overwhelming force of attraction can and will overpower anything in its way.

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.
