It's our mistakes that make us human

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.

Put poppy politics in the past and give Remembrance a hopeful future

Memory without hope will lead us to a dead-end.

Remembrance Day is complicated. A nation shows its gratitude for the service and sacrifice of its armed forces and tries to connect to its history. Never far away, are poppy politics, along with anxiety about identity and forgetting, and fears about nationalism and militarism. Is this the way to remember?

Last November, protests in solidarity with Gaza dominated the headlines. On Armistice Day, hundreds of thousands of people marched through central London to demand a ceasefire. In the preceding weeks, there was vigorous debate about whether the march should be cancelled. There were several motivations for this: there were genuine fears of violence and extremism, and of disruption at the Cenotaph, but also questions of whether marching on Armistice Day was inappropriate or disrespectful.

The march itself was organised to minimise the risk of disrupting public commemorations of Remembrance. It started several hours after the two-minute silence and followed a route several miles from the cenotaph. It was mostly peaceful, although there were arrests for anti-Semitism, open support for terrorism and violent attacks on police officers. Armistice Day did see violence around the cenotaph, but this was from the self-described ‘Cenotaph Defenders’ who had organised a counter-demonstration against the Gaza march. The group of football hooligans and far-right EDL members gathered with poppy emblazoned banners declaring ‘Have some respect for British Heroes’. Within a few hours, the calls for respect had degenerated into violent attacks on serving uniformed officers, in this case the police.

The far-right’s adoption of remembrance symbolism can be seen as an extreme form of a wider entanglement of poppies and politics. The red paper poppy is a symbol of remembrance, but it has other connotations. For some it invokes patriotism and feelings of pride in their country, for others it represents conformity and militarism. Whether television news presenters are wearing them attracts disproportionate attention. In 2019, one Australian TV network had a very tasteless segment denouncing a rival station whose newscasters failed to wear poppies. The non-poppy wearing hosts were accused of failing in their duty to respect their country and to help preserve its culture and traditions. Regardless of the presenters’ actual reasons, this feels like a lot of baggage to load onto the delicate poppy, a symbol of quiet remembrance and gratitude.

Unsurprisingly, this has led many to question whether Remembrance Day has become detached from its original purposes. Twelve years after the death of the last British First World War veteran, there is little living connection to either of the two world wars. With this passage of time, there is a growing danger of mistaking the symbols of ceremonial Remembrance for the thing itself.

The focus of remembrance can shift away from the sheer horrors of war, from awe at the sacrifice of our forebears, and from the resolved ‘never again’ to fixing our gaze on the processed goods: the ceremonial silence, the poppies themselves and even the quality of our own emotional response.

Some commentators have suggested that organised Remembrance has served its purpose and is best forgotten, and that too much remembering is a bad thing, fuelling grudges and sectarian conflicts. Personally, I’m not convinced, but I do think our current Remembrance is missing something.

With a strong grounding in a shared past and a common hope, we would talk frankly about the times our country has fallen short without a sense of betraying our history or identity.

Reflecting on the importance and difficulty of memory, the writer and Holocaust survivor Elie Wiesel emphasised the importance of hope. Despite the horrific experiences of the twentieth century, for Wiesel it is hope that “summons the future”. Memory without hope would lead us to a dead-end, where we grip onto the past while feeling it slip like sand through our fingers. Many of the anxieties around Remembrance point to a hope deficit.

How can we remember with hope?

We need to broaden our perspective and engage better with our shared national story. We need to be grounded in our history, stories and myths but we also need to be drawn forward by the good things we have and will have. If this story is big enough then it will be a large tapestry of interwoven strands, and we will be able to generously incorporate new strands, other cultures with their own relationship to the past into it. We will also be better prepared for our remembering to deal with difficult questions about our nation’s history. With a strong grounding in a shared past and a common hope, we would talk frankly about the times our country has fallen short without a sense of betraying our history or identity. Hope would connect us better to our neighbours overseas and to the men and women who risk their lives to serve their country.

Last Remembrance Sunday, I helped our church’s under-7s make big paper poppies out of red paint and paper plates. The older children made origami peace cranes, and both the big red poppies and the peace cranes were placed by the altar. Here the focus is on remembering, but not just on our own memory. For me and countless other Christians, God’s memory is the real focus. God remembers us in our broken and war-torn world, and as Jesus, chose to join us in it, experiencing the worst of suffering while dying a painful death. All our personal and collective stories of pain, loss and sadness are met in this sacrifice. More than this, in the promises of restoration Jesus gave when He rose from the dead, they find a concrete hope.

What does Remembrance look like when it’s really grounded in hope? I think there would be a few noticeable signs. It would be less precious about itself. It would be more open to different emphases of remembrance such as the Peace Pledge Union and the white poppy, and excited about new creative expressions of remembrance like the ‘poppy walks’ organised by the Royal British Legion. More patient to the concerns of those who find the religious elements of Remembrance difficult. More integrated into our attitudes to current and ongoing conflict around the world. Most of all I hope it would make us really hungry for both peace and for righteousness.
