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.

Defining cultural Christianity

There’s already a backlash against Dawkins and the New Theists.

“Richard Dawkins says he’s a cultural Christian,” I said over breakfast.

“What’s that?” she asked.

I had a stab at it. “Someone who doesn’t buy the Christian faith, but likes hymns and churches and to live in a nominally Christian country, because it’s decent. Apparently.”

“So what’s new?” she said.

She has a point. I’ve just completed a decade as a rural parish priest and plenty of people came to church because it’s a respectable, middle-class thing to do. It’s as comforting as it is comfortable.

But cultural Christianity is a thing of the moment not just because of the pop-atheist Dawkins. To be honest, he’s struggled to retain his increasingly embarrassed atheist flock over the past decade, so in the public sense he’s not much of a trophy. But there are those of higher and more surprising profiles, who have come out for Christianity as the very essence of our culture and the bulwark against something much worse (for which read Islam).

The backlash against New Theism has been swift. And, strangely, most of it hasn’t come from humanists and atheists.

A key text for cultural Christians is Tom Holland’s Dominion: The Making of the Western Mind. It posits, inter alia, that Christianity is the foundation of our civilisation, even the bits that try to destroy the faith. Holland has more recently experienced a miraculous cure from cancer through intercession (which sounds suspiciously like deal-making prayer, but never mind).

Then there’s Ayaan Hirsi Ali, whose journey from Islam to atheism to Christianity traces her developing conviction that secular humanism is a reed in the wind against the threat to the West from militant Islam. Holland and Ali, among many others, including women’s rights activist Louise Perry in her apologia for traditional Christian morality, The Case Against the Sexual Revolution, fuel the enthusiasm of Justin Brierley for a new renaissance in his joyful book, The Surprising Rebirth of Belief in God.

Collectively, these are called the New Theists, who ride against the four horsemen of the atheist apocalypse (more accurately, perhaps, the four hacks of the new millennium), Dawkins, the late Christopher Hitchens, Daniel Dennett and Sam Harris.

The backlash against New Theism has been swift. And, strangely, most of it hasn’t come from humanists and atheists, but from what one might call established Christians. I have heard the likes of Ali and Holland called cosplay Christians and their faith derided as Christianity-lite.

Dawkins still says the Christian faith is nonsense, but who’s to say the spirit isn’t moving in him?

Robert Thompson, a north London priest, has posted that “we will be in the midst of Christian revival… when we actually reorder our lives around the abused Christ and raise the abused Christ’s body”. He argues against Brierley’s championing of London’s oldest church, St Bartholomew the Great, because it’s “the gayest church in town” (no, I didn’t follow this line of argument either) and critiques Brierley’s account of Holland’s witness (if not conversion) by comparing it with “the worst Easter Day sermon I’ve ever heard”.

I accept that this is a savage paraphrase in its brevity. But it’s all there and it comes not from any of the (now old) New Atheists, but from someone ordained to the priesthood. Meanwhile, Chine Macdonald, director of the Christian think tank Theos, writes in relation to his claims of cultural Christianity that “Dawkins isn’t actually a fully paid-up follower of Jesus” and that she’ll save her excitement over New Theists until they start “talking about the ways in which their lives have been turned upside down by the radical love of Jesus Christ.”

Frankly, all this sounds a bit snobbish and patronising, as if there’s a minimum bar for Christian entry, as if it’s cosplay Christians indulging in Christianity-lite. Sure, Dawkins still says the Christian faith is nonsense, but who’s to say the spirit isn’t moving in him? Frankly, I have people at my communion rail who say the same thing. And, to be brutally honest, I can count on one hand those of my very many Christian friends who claim that their world has been turned upside down by the radical love of Jesus Christ.

To be clear, Thompson and Macdonald have important things to say. Thompson writes movingly about his pastoral experience of cystic fibrosis patients in hospital, to take theological issue with Brierley for writing about “an unbiblical God who simply does not exist” as he waited with his patients “until they died… generally well before their 40th birthday.” No Holland miracle cures, please.

Macdonald writes usefully about the difference between the word “Christian” as an adjective and a noun, the New Theists being Christian adjectives in action. She also speaks of Dawkins’ talk of Christianity as a “decent” religion (as opposed to Islam) and his feeling “at home” in a Christian country as code for “whiteness”. To my shame, I hadn’t thought about that.

This would all be an ecclesiastical spat, like arguing about angels on a pinhead, if it weren’t for a darker danger beneath it. I think of former nun Karen Armstrong’s work on the dangers of religious fundamentalism when outsiders are excluded. In that context, I worry even more about those who claim that the New Theists are the work of “the enemy”, or Satan, because they “hollow out” our faith more insidiously than atheists.

In contrast to that, Bishop Graham Tomlin gave a sermon at Lambeth Palace the other day in which he referenced Dietrich Bonhoeffer’s claim to a faith that proclaims Christ at its centre, rather than worrying too much about the boundaries of the Christian community, which are always a bit fuzzy. I like that, because with fuzzy boundaries it becomes harder to exclude New Theists.

It’s tough being a Christian, whether new or old. When a rich young man comes to the Nazarene and asks how he can acquire the kingdom of heaven, he’s told to sell all he has, give the money to the poor and follow him.

None of us can reach that bar. But the implication I hold on to is that he’ll walk alongside us anyway. And that applies to everyone in this column, without exception. Now that’s what I call radical love.
