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.

The assisted dying debate revealed the real role of Parliament

MPs from areas where people are vulnerable and at risk were more sensitive to the dangers.

What would be the effect of allowing assisted suicide for those ‘people who lack agency, the people who know what it is to be excluded from power and to have decisions made for them’, asked Danny Kruger MP, as he wrapped up his speech? ‘What are the safeguards for them? Let me tell the House: we are the safeguard—this place; this Parliament; you and me. We are the people who protect the most vulnerable in society from harm, yet we stand on the brink of abandoning that role.’  

His words capture an important aspect of Friday’s debate: what is the point of Parliament? Do MPs meet to turn public opinion polls into policies? If the majority are in favour of something, do MPs have nothing left to do but to follow the public and sort out the fine details? We might instinctively say ‘Yes!’ It seems right and democratic to treat those whom we elect as people we select and send to do our bidding. And the polls do seem to show the majority of people supporting assisted suicide, at least in principle – although there are good reasons to be sceptical about those figures and about the conclusions drawn from them.   

But there are numerous times when the majority are known to be in favour of something but politicians refuse to endorse it. Polls repeatedly show that a majority are in favour of reintroducing the death penalty. Why might it be right for MPs sometimes to ignore what the purported majority thinks and to use their own judgement?  

Because Parliament is not just a debating chamber.  

An older way of referring to it was to call it the ‘High Court of Parliament’ because ‘parliament, classically, was where individuals could seek the redress of grievances through their representatives,’ as law lecturer Dr Robert Craig writes. It performed its function admirably in response to the Horizon scandal: a legitimate grievance was brought to its attention, and it responded to redress the wrongs done to the sub-postmasters by passing a law to ‘overturn a series of judgments that could only have been obtained, and were only obtained, by a toxic, captured and wilfully blind corporate culture’.   

Friday’s debate featured many MPs who understood what they were there to do. They acknowledged the ‘terrible plight of the people who are begging us for this new law’ as Danny Kruger said. But they also spoke up for those who were in danger of being harmed and wronged by the bill: the disabled and the dying, and all the vulnerable who were not there to speak on their own behalf.  

Many echoed the concerns expressed by Diane Abbott about coercion: ‘Robust safeguards for the sick and dying are vital to protect them from predatory relatives, to protect them from the state and, above all, to protect them from themselves. There will be those who say to themselves that they do not want to be a burden. …  Others will worry about assets they had hoped to leave for their grandchildren being eroded by the cost of care. There will even be a handful who will think they should not be taking up a hospital bed.’ And evidence of coercion is hard to find and trace: ‘Coercion in the family context can be about not what you say but what you do not say—the long, meaningful pause.’  

An analysis shared on X by law lecturer Philip Murray found an association between the level of deprivation in a constituency and how likely a Labour MP was to vote against the bill. He also shared figures showing that 2/3 of MPs from ethnic minorities voted against it. In other words, MPs from areas where people are vulnerable and at risk were more sensitive to the dangers of helping people to kill themselves.  

The second reading of the bill on Friday was a crucial moment for them to decide whether the bill would fix an injustice or whether it would itself cause harm.

But it seems that many MPs did not appreciate what the debate was about or what they had gathered to do. Layla Moran MP said: ‘The media are asking all of us, “Are you for or against the Bill?”, but I urge hon. Members to think about the question differently. The question I will be answering today is, “Do I want to keep talking about the issues in the Bill?”’ But James Cleverly MP intervened: “she is misrepresenting what we are doing at this point. We are speaking about the specifics of this Bill: this is not a general debate or a theoretical discussion, but about the specifics of the Bill.” He was right to be impatient. Unlike the Oxford Union, the vote has consequences. Parliamentarians are not there merely to debate. As the term ‘High Court of Parliament’ suggests, when MPs (either on their own initiative or as a government) propose bills, what they are often doing is conveying a plea to redress some grievance, and their debates are to decide whether to respond by making laws to grant justice to the wronged.  

The second reading of the bill on Friday was a crucial moment for them to decide whether the bill would fix an injustice or whether it would itself cause harm, because the scrutiny that the bill will undergo in the following stages is not likely to be as rigorous as with government bills. As a Private Member’s Bill, the assisted dying proposal is free to be scrutinised by a committee selected by the MP who has proposed the bill, i.e. Kim Leadbeater. When the bill reaches the stage for a final vote in the Commons at the third reading, no further amendments can be made and the time for debate is likely to be short.   

It is rare but bills are sometimes defeated at the third reading. With eighteen abstentions on Friday and at least thirty-six MPs claiming they might change their minds later, there is still hope.  

Each sitting of the Commons begins every day with a prayer by the Speaker’s Chaplain, who prays that MPs ‘may they never lead the nation wrongly through love of power, desire to please, or unworthy ideals but laying aside all private interests and prejudices, keep in mind their responsibility to seek to improve the condition of all mankind.’  

We can only hope and pray that at their next opportunity, MP will consider this bill in light of their responsibilities as the country’s High Court, charged with protecting the most vulnerable in society from harm.
